 Title: That's what Big Sisters are For


Summary: My older sister takes charge of my sex life.


Keywords:inc,fic,erotic,hot,epic





   "What the fuck are you doing?!" my older sister screamed as she threw
open my bedroom door.

   As if she really couldn't tell.

   I was lying back on my bed with my boxers around my knees.  One hand was
holding my iPad in front of my face, the other was on my bare cock.  I
froze in mid-motion, halfway up the stroke.  I didn't even have time to
cover up.  A loud groan came from the screen.

   "Oh, fuck yes!" it said - the exact opposite of my actual reaction.

   My sister, Darcy, stood in the open doorway, her hands on her hips. 
Face contorted somewhere between anger and opprobrium.  She was dressed
like she was about to go to work: a pink blouse over a white tank top, and
a knee-length black skirt with dark stockings and sharp heels.  Darcy's
makeup drew attention to her pink cheeks, thick lips and bright green eyes.
Her light brown hair was tied back in a long ponytail.

   "Well, Ethan?" Darcy asked.  She started to tap her foot.

   I took my hand off my dick and turned off the video.  I put the iPad
down on the bed next to me and drew my boxers back up to my waist.  All
under my sister's disapproving glare.

   "I was...  I mean," I gestured fruitlessly at my exposed fruit, still
quite erect despite my current predicament.  I was wearing an old, yellow
t-shirt and, now, a pair of tatty blue boxers.  My hair, tight brown curls,
were in their always uncontrollable state.  Like my head was permanently
frozen in mid-explosion

   "I know what you were doing, E," Darcy said my nickname like it was a
curse word.  "I just don't understand why."

   I had a hard time believing that my older sister didn't understand my
need for self-pleasure.  I mean, I was an eighteen-year-old boy - a species
best known for its hedonist habits.  I spent most of my waking hours
working my wiener in all sorts of ways.  I doubt I was much different than
any other living, breathing male at my age (and probably some dead ones as
well).  Though she was single at the moment, my sister was no prude.  There
was no way she was that naive about the inner workings of a teenaged boy.

   To be fair, Darcy had been away at college for the last four years,
visiting only briefly for holidays.  Even summers, she spent out at
internships or living with friends.  So, I suppose my sister was used to
the (relatively) sweet, young boy she'd left behind and not this masculine,
masturbating monster.

   Darcy, now aged twenty-two, had only been back at the house for a few
weeks.  After her four years of schooling were over, she'd moved in so she
could start her career without worrying about extraneous expenses like rent
and food.  My parents, hippy-dippy folks who both worked with computers,
didn't understand their daughter's career-driven lifestyle.  But the
benefit of people like that is, even if they don't get it, they're
supportive.  Darcy could have taken a decade off to follow the Dead and our
parents would have still been encouraging.  In fact, they probably would
have understood that more

   Myself, I was more like my Mom and Dad.  High school was over, and I
supposed I ought to get a job at some point, but for the moment I was
enjoying my newfound freedom.  I was a smart kid, good with computers like
the 'rents, and I had a scholarship waiting for me in the fall if I wanted
it.  But there was a whole summer out there, man, and I wanted to take
advantage.

   I spent the first few weeks smoking pot, goofing off, and doing, well,
this: looking at porn and pulling at my penis.  I didn't have a girlfriend.
All my friends were working.  Jerking off was the height of entertainment
for me at that age.
Meanwhile, even though Darcy was back to living at home, I never saw
her. We passed each other at meals, sometimes, but mostly she was like a
ghost who'd taken up residence in the spare bedroom.  A rumor, but nothing

more.

   Well, this morning my sister was very much real and staring down at me
like she'd caught me red-handed.  Which...  Yes, OK.  She'd done exactly
that.

   "Admit it, Ethan," Darcy said.  She leaned against the door frame,
watching me carefully.  Like studying a particularly strange-looking
beetle. Masturbationus Coleoptera.  "I want to hear you confess to what
you were doing."

   I stared back at my sister, eyes goggling.  My tongue and jaw worked to
move but no sound came out.  Only a few strangled susurrations.

   Darcy sighed, then stepped into my room.  Most of the time, I was
sleeping in when she left for work.  She must have been running late or
something.  But Darcy didn't seem hurried.  Instead she casually walked
around, looking at my space like seeing it for the first time.

   My room was still dressed for high school with light blue walls covered
in posters of supercars and superheroes.  I had two beat-up, fake-wood
dressers.  My bed was a tiny twin with Star Wars sheets and a denim
comforter.  I'd decorated the floor with discarded clothes from over a
series of months.  There was a small trash can on the side of my bed and it
was overflowing with dirty tissues.  Darcy's nose wrinkled and it occurred
to me that my room was probably quite ripe.

   Finally, after completing her tour, my sister took a seat down at the
edge of the bed.  She patted the empty spot next to her.

   "Come here, E," Darcy said.

   Warily, I rolled over and sat down next to my sister.  When my butt took
the spot where Darcy's hand had been resting, she simply put her palm back
in the same place, now resting on my bare, hairy thigh.

   My big sister looked me over, but I couldn't meet her eyes.  Instead I
stared down at my overlarge, pink feet.

   "It's not right, Ethan," Darcy said, "What you're doing to yourself. 
You know that."

   "Come on Darcy, what's the big deal?" I said, finally finding my voice.
It was whiny and oddly high but at least it was there.  "I mean, I'm sorry
you caught me and all.  I'm sure that was uncomfortable.  But everybody
does it.  Don't pretend that you don't."

   "You don't get it, do you?" Darcy said.  She slid her hand slightly up
my thigh, to the point where her pinky was actually touching the bottom of
my boxers.  "It's wrong for you to do that when your big sister is around."

   "I didn't know you were here," I said, "Usually you're at work by now."

   "Hm," Darcy said, as if considering my argument, "You know what?  That's
fair." Her hand slid up further.  Now her pinkie was actually under my
boxers.  The nail, painted a neon pink like the rest of her fingers,
tickled at my shaft.  I couldn't hold back my gasp as my sister's finger
made contact then dragged up and down my cock.

   Like I said, I didn't have a girlfriend.  In fact, I'd never had one. 
There were a few sloppy makeout sessions with Cara O'Brien during summer
camp my junior year, but that was the limit of my experience.  No one,
besides myself (and a physician, probably), had ever touched me below the
waist.  My sister's little finger felt fantastic and my cock responded in
kind, staggering upward till it poked through the fly hole of my underwear.

   I froze.  I expected Darcy to recoil.  To jump off the bed and start
shouting all over again.  Instead, she just smiled.

   "There's a good boy," she said.

   My older sister took her hand off my leg.  She daintily pulled the hole
of my boxers open, allowing my dick to fully pop free.  It pulsed in the
cold air.

   "You shouldn't be stroking your dick when I'm not around, either," Darcy
said.  "In fact, you shouldn't be stroking it at all.  Ever."

   My sister grabbed my shaft and gave it a squeeze.  She gathered the
loose skin around my dick and dragged it over the circumcised head, slowly
teasing, then pulled it back down, taut.  She reached into the leg hole of
my boxers with her free hand and cupped my balls.

   I'm sure all of this sounds hot.  My sister sitting on my bed and
stroking my cock.  But the truth is, it weirded me out.  My mind, my heart,
was racing.  My stomach twisted.  Really, my dick was the only one on board
with this and he was not an impartial observer.

   I just didn't find my older sister attractive.  That's not to say that
she wasn't good looking.  She very much was.  Darcy had a thin face with a
cute upturned nose and perfect Cupid's bow lips.  Her cheeks dimpled when
she smiled.  Her brown hair was long and thick and, when it wasn't tied up,
hung all the way to the middle of her back.

   And Darcy's body was, well...  I mean, she was a beautiful woman in her
early twenties.  Darcy was tall and thin with a flat stomach and long legs.
She had a perky butt and big breasts - I had no idea the cup size but I
could tell by the cleavage in her work outfit that there was a lot there.
Darcy always dressed well.  Her outfit that day - complimented by her
painted nails and diamond stud earrings - was that wonderful mix of
professional and sexy.

   So objectively, sure, this was a gorgeous woman working me off.  But it
was also my older sister and I couldn't get past that.  However, when I
asked her to stop, Darcy shook her head and kept stroking.

   "You have to promise me, E," Darcy said.  "Tell me you've learned your
lesson." She rubbed me up and down at that leisurely pace.  My breath came
out in little gasps and rattles.  My body was torn between disgust and
desire.  What was my sister doing to me?

   "You're a teenaged boy with raging hormones," Darcy said, "I get that.
You probably need to bust a nut at least twice a day, right?"

   "Uh huh." It was usually more than that, but I was lost for words. 
Darcy rubbed my dick, rhythmic, like rowing a boat.  Stroke.  Stroke. 
Stroke.

   "But there's no reason for you to do that to yourself when your big
sister is right across the hall and happy to do it for you, right?"

   And there it was.  Darcy's mission statement made clear.  She wasn't mad
about me masturbating.  She was upset that I didn't let her rub me off,
herself.  That made so much sense and yet was also completely insane at the
same time.  Like I wasn't discombobulated enough already.

   "So, from now on, if you need to empty your balls, just come find me and
I'll do it for you, OK?"

   "But Darcy, I mean.  Isn't it, like, wrong?" I asked.  I don't know what
I thought would happen if I argued.  Like, if I brought up a rational
point, did I really think my older sister was going to suddenly stop and
remember herself?  Yet I continued to debate her.  "You're my sister.  We
aren't supposed to do stuff like this."

   "Of course we are," Darcy said cheerfully, "That's what big sisters are
for.  To take care of their little brothers."

   "Darcy, please don't take this the wrong way.  I really really
appreciate what you're doing, and it feels really really good but it's not
right and I don't like it.  Please let's just stop, OK?  I promise you'll
never catch me jerking off again."

   "You're right I won't," Darcy said, "So we're agreed?" My older sister
looked me right in the eyes.  She was slightly taller than me, so she had
to scrunch down a bit to do it.  Her green eyes were gorgeous, whorled with
brown, and they seemed to swallow me up in an emerald undertow.

   "I..."

   "Like you said, this feels really good.  Right Ethan?" Darcy started
moving her fist up and down even faster.  My body was betraying me.  I
didn't want to like this.  But I couldn't stop myself.

   "Y-yes."

   "You can have this every day, anytime you want.  Just let me take care
of you.  OK?"

   I took a deep breath.  I don't why, but in that moment, I didn't feel
like I had much of an option.  It was either agree right then or argue more
until I eventually agreed later.  So, the choice seemed kind of obvious. 
"OK."

   Darcy's face broke into a broad grin.  She took her hand off my cock,
then spit in her palm.  She showed me, like a proud little girl, then
draped her drippy hand all over my dick.  Then she grabbed me in her
slippery grip.

   Darcy started stroking me.  At first, she used that same slow motion
from before, but she gradually gained speed.  Every movement made a wet
noise, like stirring mac and cheese.

   Squick squick squick.

   My older sister was jerking me off even better than I could do myself.
Just the foreign feeling of a strange hand working me was enough to take it
to a new level.  But Darcy also knew the exact pace and pressure to drive
my pleasure.  It was both horrifying and incredible at the same time.

   "That feel good?" Darcy asked.

   "Uh huh," I said.  It was all I could get out.

   Squick.  Squick.  Squick.

   "Of course it does," Darcy said, almost cooing.  She took her other hand
out from under my boxers and started to stroke my hair, lovingly.

   "Oh God," I said.  A bit of precum leaked out of my cockhead.  Darcy
gathered it and used it to lubricate me even more.  She was pumping me as
fast as she could now.

   Squick squick squick squick squick.

   "You going to shoot for me, little brother?" Darcy asked.

   I had been staring down at where my sister's hand met my dick.  Now I
turned to look at her face, all screwed up in concentration as she worked
me over.  She caught me watching and smiled back at me.

   "Yes, baby.  Do it.  It's alright.  Show your big sis what a good boy
you are and give me your cum."

   "Ah.  Ah.  Ah." It was the only sound I could make.  These weak little
gasps.  Suddenly my cock jerked.  My balls jumped upward.  The pleasure
raced up my shaft and exploded throughout my body.

   "Oh!" Darcy cried in surprise as the first thick rope of semen shot out
of me.  She slowed her strokes, drawing out my orgasm.  I spurted again and
again.  "Oh yes!"

   After what felt like minutes of constant cumming, I finally dribbled the
last of my spend onto my older sister's fingers.  Darcy patted me on the
back with her clean hand.  She took the other one and brought it up to her
mouth, lightly licking off my spend.

   "Thank you, Ethan," Darcy said.  My sister had just jerked me off,
tasted my sperm, and now she was thanking me?  This morning was only
getting stranger.

   Darcy stood up and straightened her outfit.  "That'll have to do for
now, I'm already running late to work.  Remember our agreement, OK?"

   Then, as suddenly as she had entered some twenty minutes before, my
older sister disappeared from my doorway.

   *

   I spent the afternoon in a funk.  I sat on the living room couch,
streaming Netflix, but nothing caught my interest.  I kept having the odd
sense that I was forgetting something.  That I'd planned something exciting
for the day but wasn't doing it for some reason.  Then I remembered what
happened that morning and sank deeper into the couch.  Not even my
afternoon pipeful of weed could perk me back up.

   My parents came home, and my Mom made dinner for the three of us.  Like
me, my Mom and Dad were small, skinny people.  Both of them had gone
prematurely grey.  They were former flower children (albeit born a decade
after actual flower children had existed), and they looked it.  My Dad had
long gray hair tied back in a ponytail.  My Mom wore concert t-shirts and
hipster glasses.

   If Darcy had been at dinner, she would have looked like she was adopted
or the mailman's kid or something.  She was the fourth Mendel square, the
sum total of all our family's recessive genes mixed into a singular being.

   Where my parents were laid back, Darcy was driven.  Mom and Dad were
both simple, lunch pail folks who spent more time on their record
collection than on getting ahead.  Darcy was a true professional, ready for
a world of high-powered businesspeople and the fancy toys that came with
that.  My parents cared about squishy things like feelings.  Darcy,
obviously, did not.

   "You OK?" my Mom asked, "You seem a little down."

   I looked up from where I was chasing my peas around the plate with my
fork.  "I'm fine," I said.  There was no way I could tell my parents what
had happened.  It was too embarrassing.  Besides, what argument did I have?
After all, I got hard when Darcy grabbed me.  I came when she stroked me. I
was just as guilty as she was.

   "Spending all day by yourself at home finally losing some appeal?" my
Dad asked.

   "Maybe," I said.

   "OK, well you let us know," Dad said, "This doesn't have to be your
life. That college scholarship is waiting for your signature." He patted my
back warmly, then got up to dig through the freezer for leftovers of my
Aunt Penny's blueberry pie.

   "We support you, no matter what you do," Mom said, "We just know that
you can make choices now that will have consequences for the rest of your
life.  Getting a job, going to college, you don't have to do both, but you
can't do neither."

   "I know," I said, but it came out as more like a whine, "Can't I enjoy a
little freedom before then?"

   "Of course, dear," Mom said.  She stood up to go help my Dad in the
kitchen.

   I followed her in, dumped half my dinner in the trash, and then loped
upstairs.

   I changed into my pajamas and climbed into bed.  I tried to read for a
bit, but I found I was looking at the same sentence again and again. 
Finally, I slipped under the covers and curled up, fetal, to fall asleep.

   *

   I woke up to the sound of my door opening.  My room was dark, but I
could see the shadow of my older sister from the light in the hall.

   "Hey E," Darcy said.  She sat down on the side of my bed again.

   "What time is it?" I asked.

   "Late," Darcy said.  "I hurried back as soon as I could.  I knew that
one this morning wasn't going to be enough.  It must have been so hard for
you to suffer through the day without your big sis.  Well I promise to make
it up to you.  You did wait for me to take care of you, right?"

   "Yes," I said.  I didn't tell her that I'd actually tried to rub one out
in the afternoon and couldn't, still shaken from what had happened that
morning.

   "Excellent," Darcy said and clapped her hands.  She started to pull back
my covers.  When she saw I was wearing pajama bottoms and a t-shirt, she
made a little pouty face.  "You didn't give up on me, did you?"

   "Honestly, Darcy, I just want to pass out," I said.

   "I know, baby bro, that's why I hurried back as soon as I could.  I knew
there was no way you could get to sleep without some release.  Jeez, I hope
the one will be enough.  I don't think I have the energy for a double
tonight.  You'll have to let me make it up to you, OK?"

   Darcy pulled at my shoulders until I sat up.  I was woozy, and I almost
tipped right back over, but she held me there.  Then she shot her hand into
the fly of my pjs.  My dick was curled up in a ball, like a sleepy little
mouse.

   "Oh, so cute!" Darcy said, "Don't be ashamed.  I know my brother has a
big, mean man dick.  We just have to wake him up, that's all."

   Darcy stroked my soft penis up and down.  Honestly, she didn't even need
her fist, I was so flaccid she could almost pinch it between her fingers.
My cock gave a half-hearted attempt to respond, but the rest of my body was
still in control and it didn't like the idea of my sister doing this to it.

   "What's wrong?" Darcy asked, "You feeling alright?"

   "I don't like doing this with you, Darcy, OK?" I said.  "You're my
sister and it weirds me out."

   "You sure didn't feel that way when you came all over my hand this
morning," Darcy said.  She got up from the bed.  Then she went over to the
wall and flicked on the light.  I saw she was wearing her same outfit, but
her blouse was unbuttoned halfway, revealing even more of the white cotton
of her undershirt.

   My older sister caught my eye, looking confused.  Then she gave me that
face-splitting smile again.

   "Oh, I get it," Darcy said.  "Boys all love boobies, don't you?  OK,
bro, you've 'tricked' me into it." Darcy reached down, unbuttoned the rest
of her blouse, and pulled it off.  Then she lifted the white tank top over
her head.  She had on a dark green bra underneath.  Her breasts, even
bigger than I'd first assumed, seemed to be bursting out.

   "Darcy," I said, "Please don't."

   "Is that enough?" my older sister asked, "Or do you need to see all of
them?" She looked down at my crotch.  Sure enough, my traitorous dick was
sticking proudly out of the fly, throbbing away.  "That's enough!" she
cried, happily.

   Darcy bounced onto the bed and grabbed my dick.  It was now so full, she
could barely wrap her hand around it, and a good three inches stuck up from
above her fist.  I guess I'm a grower, not a show-er.

   My older sister gave me a few strong pumps.  "I don't suppose you have
any lube in here?  I mean, I'm fine to use my spit, but I bet it'd be even
better with some moisturizer.  No?  OK, I'll go buy you some in the
morning. Trust me, it takes things way over the top."

   Again, Darcy licked her hand and slathered it over my cock and balls. 
She gripped me tight and started pumping.

   I tried to reach down and block her from doing it, but she shoved my
hand away.  "Don't worry, I've got this," Darcy said.  "You just look at
your older sister's big titties and enjoy."

   It didn't take long for my sister to milk my cock.  Somehow, she seemed
even more skilled than this morning.  It was embarrassing, realizing my
sister had more control over my body than I did.

   A moment later I was spurting.  This time, Darcy anticipated it and
caught it all in her hand.  She tipped my spend into her mouth with a
hungry grin, then wiped the remainder across her bare chest.

   "You like-y?" she said, jiggling her tits a little.  "Oh, I bet you do.
Maybe next time you can cover me in your cum straight from the source."

   Darcy stood up and grabbed her shirts off the floor.  She balled them up
and headed towards my door.  "I'm assuming you're going to need another go
first thing when you wake up, right?"

   I tried one last chance to plead my case.  "Please, Darcy," I said, "I
really don't like this."

   "Your dick seemed plenty hard a minute ago," she said, quirking her
lips, "Seemed like you 'liked it' fine then.  In fact, the only time I hear
you complaining is when I'm not stroking you off."

   I didn't have a response for that.

   Darcy sat next to me and patted my head.  My curls sproinged under her
touch.  "I get it," Darcy said, "You're a good kid and you don't want to
hurt me.  Well, don't worry, OK?  Just relax and enjoy yourself.  That's
more than enough to make me happy."

   Darcy leaned over and kissed my cheek, then she slipped out of my
bedroom, switching off the light as she went.

   "Sweet dreams," she said, her voice drifting through the bedroom door
and wrapping itself tightly around my chest.

   *

   I woke up to something warm and wet latched around my cock.  I went from
half asleep to fully awake in seconds.  I ripped the covers off and saw my
big sister making love to my dick with her mouth.  She grunted, then went
back to working me over.

   Darcy looked like she'd just woken up, herself, wearing only a light
blue t-shirt and a pair of pink hipster panties.  Her hair was tied back in
a tight bun.  Without makeup, without a minute of work to put herself
together, my sister still looked incredible.  Even I had to concede that.

   My older sister slurped up and down my hardness.  Her fist followed her
mouth, corkscrewing along the way.  I'd always thought of blowjobs as
something girls did because they had to, not because they wanted it.  But
Darcy made it look like she was getting the treat of a lifetime to lick my
dick.  It would have been wonderful, all of it, if only it wasn't my sister
kneeling over me.

   "Darcy," I said.  It was the only word I could say, and it carried so
much.  Desire and disappointment in equal measures.

   My sister pulled off my cock with a pop but kept idly stroking me with
her hand.  "Hey bro," Darcy said, cheerfully, "I need to get ready for
work, but I didn't want to leave you without your morning workout." She
winked at me as she said that last word, like I might not get the joke. 
"Anyway, I was thinking again about lube and I realized, duh, I can use my
mouth!  Your sister is such a dumb slut sometimes."

   I started to respond, but Darcy dove down and started sucking my dick
again.  Any hopes I had of forming words were swallowed in my sister's
sweet mouth.

   "Cum when you're ready, OK?" Darcy said, "Don't feel like you've gotta
hold back on my account or anything.  Just warn me when you're going to
shoot.  I want to be ready for it."

   If I'd thought my sister was giving her all before, I found I was sorely
(fantastically) mistaken.  Darcy cradled my balls with one hand while she
pumped my cock into her mouth with the other.  All the while she sucked on
my dick with a tightness I doubted even my own fist could match.  This girl
could pull a golf ball up a garden hose, I swear.  Getting me to cum was
almost nothing.

   "Darcy," I gasped, the only word of warning I could produce.  The
pleasure gripped my skull, squeezed at my eyes, as I exploded into my
sister's waiting mouth.  She gasped, then gulped.  Loud swallowing sounds
that I swear she was amplifying for my enjoyment.  I was so ground down by
ecstasy, I could barely hear them over the roar in my ears.

   When I finally recovered, I saw my sister perched over me.  She stuck
out her tongue to show the last of my sticky fluid.  Then she made a big
show of swallowing it down.

   "You are extra, super tasty," she told me, then patted me on the head.
Her fingers caught up in my curls.  "I know, I promised you could do it on
my big boobs, but that tastes so nice it's hard not to swallow it all."

   Darcy made those same gulping noises as before, then jumped off the bed.

   "Gotta go, little bro," she said, "Some of us have to work, you know."
She padded out of my room.  I lay back in bed, shellshocked at what had
happened.  My sister had sucked me off, right out of sleep, and all I'd
managed to do was say her name twice.

   *

   I woke up at around lunchtime.  I'd been keeping teenager-like hours,
but this was late, even for me.  I got up and showered, then dressed.  The
house was totally empty.  I made myself lunch, smoked a bowl, then sat down
and fired up my PS4.  I tried to lose myself in shooting zombies, but my
mind kept drifting back to that morning.  To the day before.

   I'm sure a lot of you think I'm an idiot.  After all, I had an
(admittedly) gorgeous woman getting me off at least twice a day.  Most of
you, I bet, think I should have been throwing a parade, not sitting around
sulking.  And look, I won't lie, doing dirty stuff with my sister felt
amazing.  So long as I didn't think about the fact that it was dirty
stuff with my sister.

   The truth is, I didn't want to feel upset about it.  I told myself to
let it go, to lay back and enjoy it.  I couldn't.  Some part of me wouldn't
let go of the fact that it was my sibling who was doing me.  I
didn't think it was wrong, I knew it was.  It was a gut instinct and,
appropriately, it turned my stomach sour.

   So instead of saving the world that afternoon, I went for a long walk
around the neighborhood and composed my thoughts.  Gradually, I put
together an entire monologue that would convince my older sister to stop
what she was doing.  It was respectful, well thought out, and inarguable. I
even plotted out what Darcy would say and developed possible responses. 
Our illicit congresses would end that night.

   My parents came home and made dinner.  Afterwards, I went up to my room
and forced myself to stay awake, waiting for my sister's return.  At around
ten, I heard her car pull up in the driveway.  The front door opened.  Her
footsteps went straight to my room.

   "You stayed up for me!" Darcy said, looking genuinely pleased.  "Oh,
poor baby, I bet you couldn't sleep at all without me here to help you. 
Well, let me get comfortable so I can take care of you."

   Darcy was wearing a dark, navy skirt with a matching jacket and a blue,
pinstriped blouse.  Her hair was up, her makeup was perfect, but her eyes
looked tired.

   "Long day at work?" I asked.  Empathy was part one of my master plan.

   "Usual," Darcy said, waving me off.  She walked across the hall and I
followed her into her bedroom.  She hadn't changed it all that much from
her high school days: there was a twin bed, a desk with a little laptop,
and several large dressers.

   "Ooo, naughty boy.  Trying to catch me changing?" Darcy said as she
undid her earrings.  I ignored her flirting and got back to the point.

   "I think it's unfair, the way they expect you to work all these hours,"
I said.  I sat down on Darcy's bed.

   "Of course it's fair," Darcy said, "It's my first job out of school and
I expect them to pay me a lot of money someday.  I'd be mad if they didn't
make me work for it." She kicked off her shoes - losing a couple inches of
height - and turned around, still in her dress shirt and dark skirt.  "Will
this be enough for you, or do you want me to take off more?" She licked her
lips, lasciviously.

   I took a deep breath and started my spiel.  "Darcy, you and I haven't
been close for a long time, so I know that you might see me as..."

   "Maybe I should lose the shirt," Darcy said, "And the skirt.  I don't
want to get any of your special stuff on these.  Pain in the ass to get it
cleaned." She unbuttoned her dress shirt and tossed it on the bed, then
unzipped her skirt and stepped out of it.  My older sister stood in front
of me in a lacy white, plunge-style bra, matching panties, dark nylons, and
nothing else.  She put her hands on her hips and tilted her head, like she
was actually listening.

   "...just don't want to make a mistake and do something we'll both
regret," I said.  I took a deep breath before moving to the next part. 
"That's why..."

   "Ethan, I know where you're going with this, so let me stop your right
there," Darcy said.  She sat down next to me and patted my thigh.  I was
wearing jeans and a t-shirt, trying to look as unappealing as possible.  "I
appreciate you speaking to me honestly.  And look, I get it.  I feel it
sometimes, too.  But no matter how much you want to, we can't have sex."

   "That wasn't..."

   "We're brother and sister," Darcy said, "It would be really wrong to do
that.  So, while I'm more than willing to help you out with your 'needs,'
we can't go any further than that, OK?  But don't worry, there's lots of
other fun stuff we can do together.  I promise."

   With that, Darcy slipped down off the bed and knelt between my legs. 
She undid my belt, and shucked my pants, underwear and all, down to my
knees.  I was so shocked at how quickly she moved, so bamboozled by what
she'd said, I didn't even realize I'd lifted my butt to help her get my
jeans down until my bare dick was pointing right up at me.

   It wasn't bare for long, though, as Darcy almost immediately engulfed it
in her eager mouth.

   Slurp.  Slurp.  Slurp.

   Again, my sister seemed to have learned how to please me even more
between sessions.  Her oral skills went from incredible to off the charts.
I closed my eyes and tried to picture someone else giving me head.  My mind
ran through images of old crushes, girls I went to school with, anyone. 
Nothing stuck.

   My eyes popped open.  Darcy was slurping on my cock.  She looked up at
me.  Her deep green eyes caught mine.  She dragged her hand right up my
shaft and that was it.  I didn't want to cum that way, but I blew my load
looking straight at my sister.

   Darcy took my first shot right down her throat.  Then she pulled off and
aimed me at her chest.  My cock blasted over her tits.  You'd think, after
all this stimulation, the volume of my seed would be less.  If anything, it
seemed to increase each time that Darcy did me.  My stomach twisted as I
splattered my sister's bra-covered breasts with my seed.  My body had
betrayed me again.

   Darcy stood up and pulled me to my feet.  She kissed my forehead, then
patted my ass, as if to send me on my way.

   "See you in the morning," Darcy said, then gently pushed me out,
shutting the door behind me.

   I stumbled out into the hallway.  My Dad was coming out of the bathroom,
and we both startled.

   "You OK?" he asked me.

   "Uh huh," I said, somewhere between shocked at what had happened and
stupid with post-orgasm bliss.

   "What were you doing in Darcy's room?" my Dad asked, warily.

   "Oh, you know," I said, trying to force myself to sound casual (which,
by the way, is the worst way to sound casual), "I had a problem she was
helping me out with."

   "You're not wearing pants," my Dad pointed out, oddly rational.

   "Yes," I said, "That was the problem."

   Dad raised his eyebrow.  I wandered back to my bedroom and shut the door
before my father could interrogate me any further.

   *

   I slept fitfully, wracked by erotic dreams of doing debauched things
with my sister.  I startled awake and saw, who else, sitting on the side of
my bed.  Darcy was wearing another t-shirt and panties combo, this one
royal blue on top and canary yellow on the bottom.

   "Hey little bro," Darcy said, "Or should I say big bro?" My sister
looked down at my crotch, meaningfully.  My dick stood at attention, like
it was a new recruit and she was a high-ranking officer.  I told myself it
was the dreams that had me hard.  Simple biology, right?  Morning wood and
all that.

   Darcy gave me her now-familiar wink.  "I need a shower," she said, "And
so do you."

   My sister grabbed my wrist and pulled me out of bed.  As we crossed the
hall, I saw my parents' bedroom door was open and their room was empty.

   "They left about ten minutes ago," Darcy said, answering my unspoken
question.  She dragged me straight into the bathroom.  It had been built in
the 1960s and it showed, with pink tile and gray grout.  We had one of
those tub-shower things with tinted, sliding glass doors.  Darcy reached in
and turned on the water.  It hissed and popped, then finally streamed out.

   Then, like it was nothing, my sister pulled her t-shirt over her head. I
couldn't help it.  I goggled as Darcy's bare breasts appeared before me. 
Somehow, we'd done all this, but I'd yet to see her completely topless.

   Darcy's chest was as impressive a sight as anything I'd witnessed in my
young life.  She had a pair of massive mounds that were at least two sizes
too big for her skinny body and topped with tight, cherry nipples.  My
sister saw my reaction and a smile crept across her face.  Her cheeks even
went a little pink.  Darcy shook her chest for me, and I swear my eyes
jiggled right along with her boobs.

   Then she straightened.  "Come on," Darcy said, "I have to get going or
I'll be late for work." She reached over and started pulling my shirt off
me.  I took the hint and got out of my clothes.  I was naked in front of my
big sister.  Strange that it was so casual, but I guess after someone has
sucked your dick a few times, them seeing you naked doesn't seem like that
big a deal?

   I mean, I guess I looked ok.  I had my high school body which could eat
for days and still look trim.  I had dark chest hair on my pecs and
stomach, though not enough to be a gorilla.  I looked like me, is what I'm
saying, which is neither a compliment nor an insult.  Still, my sister gave
me a smile of approval as she saw me totally naked for the first time.

   Then it was her turn.  Darcy pulled her panties off with a flourish and
tossed them off to the side.  My older sister had a small tuft of brown
hair over a pair of very tidy labia.  Her pussy split open slightly at the
top, revealing her little clit, but otherwise it was taut, almost demure.

   Finally, as if this was the biggest reveal of all, Darcy reached back
and undid her hair, letting her long, golden-brown locks fall free.  Her
hair hung down to slightly above her stomach, covering her breasts in a way
that almost made them more alluring.  Again, my sister caught me staring.
Again, she blushed at my attention.

   I'd seen plenty of naked women in my life.  OK, in pictures and video
clips but still.  I'd never witnessed anything like this.  Darcy was an
apex woman.  The feminine ideal with long hair, wide hips, flawless skin
and a sexy smile.  For a moment, for the first time, my brain shut down and
let me appreciate what I was looking at.  God damn I wished she wasn't my
sister.

   Darcy bent over to test the temperature of the water, giving me a good
look at her pert little butt and plump, purple pussy.  She did a little
shimmy and stood up.  "I think it's ready," Darcy said, "I can tell you
already are." She hefted my dick in her hand, then grabbed it and used it
to pull me into the shower with her.

   My older sister giggled as we got under the water.

   "You soap me first," Darcy said.  She handed me the body wash and a
loofa.  I figured I should take this seriously, so I started on her stomach
and legs.  Darcy watched me do this with a playful smirk.  Then she reached
down and put my hands on her breasts.

   They were soft, overflowing my hands, and lovely to touch.  I lifted
Darcy's boobs.  Pinched her deep red nipples.  Darcy gasped, then grinned.
I did my best to shout down that part of my brain that didn't like this. 
It was getting easier, which was almost worse.

   My sister turned around and let me soap her back and bottom.  That was
another new experience, squeezing Darcy's heart-shaped ass.  Again, I told
myself, there was nothing wrong with this.  It's fine to have a little fun.
Like she'd said, we weren't having sex.

   And that was the moment I had my revelation.  There, on my knees,
cupping my sister's buttcheeks in my palms, pretending to be cleaning them.
Darcy had said it herself: no sex.  Was this really so wrong, then?  I
mean, I was naked in the shower with a beautiful woman.  Who cared if she
was my sister, honestly?  And if we weren't having actual intercourse, was
it so bad to be together?

   I gave my sister a little kiss on her butt.  She play swatted at me,
then turned around.

   "Your turn!" Darcy announced.  She grabbed the soap, lathered it between
her hands, and grabbed right for my cock.  Holy fuck!  My knees wobbled,
and I almost toppled over, it felt so good.

   "See?" Darcy said, "Lube." She used both hands to stroke me up and down.
It took three pumps, maybe, before I was splattering the tub with my spend.

   I stood under the steaming water, panting.  I had my hand on the tile
wall to hold myself up.  Darcy hadn't so much jerked me off as she had
milked me.  Just ripped the orgasm out of my body.  Left me a hollowed,
exhausted shell.

   Darcy held up her hand to show me it was covered in cum.  The water
quickly washed away the thick strings between her fingers.

   "I know you've been struggling with this," Darcy said, "Twice a day
isn't enough for a boy your age.  But today is Friday and I promise, we'll
get some serious work done on the weekend."

   She kissed my forehead, very matronly, and slid open the shower doors. I
was still standing there - soaking in the hot shower and short of breath -
as I heard my sister's car race out of the driveway.

   *

   I spent the whole day enjoying my newfound rationalization.  All of this
was fine, even fun.  As long as we didn't have sex, I could (should!) be
enjoying my sister's attention.  How many guys would kill for this
situation?  I knew a lot of my friends crushed hard on Darcy.  If I told
them she was giving me two-a-day oral exams, were they going to be
disgusted?  I doubted it.

   Did my stomach twist a little, thinking about what my sister was doing
to me?  Sure.  But I told myself that I wasn't allowed to feel that way. 
Darcy was doing me a huge favor, a kingly kindness, and I was going to
enjoy it whether I wanted to or not.  Again, as long as it wasn't sex, it
was OK.  That was my new mantra.

   Feeling better about all of this, I had my first pleasant day since it
started.  I smoked up, played videogames, blared my music, and had fun. 
When my parents came home, they made dinner, and we had a lovely, chatty
meal.  If my Dad was worried about our encounter in the hallway from the
night before, he didn't say anything.

   That night, Darcy came into my room wearing black, thong panties and
nothing else.

   "You enjoyed my boobs so much this morning, I thought we could try
something different," Darcy said.

   She climbed on the bed and wrapped her breasts around my cock.  I was
already hard, of course.  My sister had my dick better trained than I did.
She moved her tit flesh up and down my dick slowly, looking up at me and
daring me to stare back.

   "Here, the angle's wrong," Darcy said.  She lay down on the bed, next to
me.  She held her boobs in position, squeezing them forward.

   I froze.  To this point, this had all been stuff my sister was doing to
me.  I'd never even moved, actually, unless you counted the spasms of my
shlong.  Now she was lying on her back, waiting for me, and it felt weirdly
like a big step.  As if this was some new threshold we'd yet to cross.

   My sister didn't move, she just lay there.  I got the feeling she'd stay
all night unless I did something.  So, I rolled over and spread my legs
over Darcy's torso.  Then I slid my dick into the tunnel between her tits.

   "See, much better," Darcy said.  She held her breasts tight around my
hardness and, slowly, I began to hump her chest.  Every time my cockhead
popped out of her cleavage my sister gave it a little kiss.

   This felt different.  It shouldn't have been, really.  In fact, it was
probably less invasive than the blowjobs I'd grown used to.  But something
about the way I rocked back and forth on my sister's body, it felt like way
more.

   Maybe it was how the movement seemed awfully close to fucking.  Or the
fact that I was the one now actively getting myself off, using my sister's
body to do so.

   "I want you to cum, Ethan," Darcy whispered, "I need you to.  Shoot
your stuff all over my face.  Mark me.  Do it.  Give your big sis what
she's begging for.  Pleeease."

   Darcy's body was incredible.  Fucking her tits was amazing.  But it was
her words that put me over the top.  As my soon as my sister started
begging, my sperm rocketed out of my shaft.  I did as she asked, spurting
on her face.  Long white drips hung off her nose.  One eye shut where I'd
accidentally splashed her.

   Darcy giggled and licked herself clean, like a kitty.  "I missed that
this morning," Darcy said.  She gave me a tight hug.  "Oh, I wish I could
stay in bed with you, too, baby.  But Mom and Dad would not appreciate
finding us like this."

   My older sister stood up, wiping the last of my cum off herself.

   "Thanks, Darcy," I said, plaintively.  It was awkward.  But in the
moment, I felt like I had to say it.

   "Of course, sweetie," Darcy said, "I'll see you tomorrow.  That's when
the fun can really start."

   *

   I was already awake when Darcy came in my room the next morning.  She
looked at me with glee, like we were going to Disney World, not doing our
now-daily ritual.

   "Today's going to be so awesome," Darcy sang to herself.  I couldn't
help but get caught up in her enthusiasm.

   I stripped off my boxers and let my dick spring free, somehow as hard as
I'd ever seen it.  Darcy was wearing her usual uniform: t-shirt and panties
(pink and blue, respectively) with her hair tied back.  She knelt between
my legs and slowly teased at my cock, dragging kisses up the shaft.

   Darcy slithered her hand around my dick and popped the head in her
mouth. She hummed, happily, vibrating in a very pleasing way.  Then she
began deliberately working me.  Every time was different with Darcy, and I
guess that's what made it so amazing.  I could never get used to one
sensation before being introduced to a new one.

   I realized how hurried my older sister had been with her oral
performances up till then.  I'd thought she was concentrating on my
pleasure, but, in fact, she'd been getting me off quickly so she could get
to work.  Now Darcy took her time, she edged me slowly forward, inch by
incredible inch, building me up to something that started to feel volcanic.

   My sister sensed me building and she increased her speed.  Made sexy
little slurps and chokes.  I was on the precipice now.  I could feel it
building.  My sister could have breathed on me and I would have blown.  But
she wasn't breathing.  She was sucking, stroking, slurping, and suddenly...

   Darcy stopped.

   My sister dropped my dick and sat up straight.  Her butt perched on my
knees.  I was already gasping for air.

   "So," Darcy said.  She reached up to play with her hair, twisting it
around her finger like a little girl.  "I've been thinking.  Since I've
been doing this stuff for you - you know, getting you off - that you might,
like, be willing to do the same for me?"

   Honestly, my sister could have asked me to leap off the Ben Franklin
Bridge at that moment and I'd have agreed without thinking about it.  And,
to be fair, Darcy asked for relief in a way that made it seem equally as
dangerous.  But I was honestly fine with it.  She was right, I should be
returning the favor.  In fact, I felt bad that she even had to ask.

   "Oh, I knew you'd understand," Darcy said, "Here, why don't you do me
and then I'll finish you off."

   My older sister fell next to me on the bed.  She stripped off her
panties and flung them across the room.  Then she spread her legs.  I
noticed that the patch of hair that had been there the last time I saw her
pussy was gone.  Darcy had shaved her snatch completely.

   "Use your fingers, OK?" Darcy said.  She grabbed my hand and put it in
the warm space between her legs.

   My sister was already dripping, and her sex felt almost hot to my touch.
I dragged my finger through her slit.  Darcy arched her back and sighed.

   "Oh God," Darcy said, "You are really terrible at this." She got up on
her side and fixed me with a very serious look.  "OK, little bro, don't
worry.  I'll show you."

   Very patiently, my sister took my hand and showed me what she wanted me
to do.  I got a guided tour of Darcy's cunt, where to touch, how, and when.
What to feel for, what to listen for, and what to avoid completely.

   "There's more stuff," Darcy said, "But I think that's enough for now."

   I put my hand back in my sister's pussy.  I teased at her slit, then
scooped her moisture up and bathed her clit with it.  I gradually rubbed
her little nubbin back and forth, then slid a finger from my other hand
inside her sex.  This time, Darcy groaned with pleasure.

   I started stroking my sister's clit faster.  I put my finger inside her
pussy and felt it squeeze down.  A lot like her mouth would do on my dick,
actually.

   "Oh, that's much better," Darcy said.  She gave me a self-satisfied
smile, then reached over and grabbed my cock.  It hadn't flagged for a
moment in all that time, though my orgasm was now less impending.  "We'll
get off together, OK?"

   I nodded, staying focused on making my sister cum.  I pumped her pussy
with my fingers and ground her clit with my thumb.  Darcy's breath hitched.
She grabbed my wrist and held my fingers in place.  Her back arched and she
made a low moan.

   Darcy's hand squeezed my dick so hard it almost hurt.  With a remarkable
quickness, she jerked me - one, two, three - and I reached my own orgasm.
My spend shot out.  I heard my sister continue to cum with me.  Both of us
lost in our own solitary pleasure, lying next to each other on the bed.

   My cock softened.  Darcy's pussy tightened, expelling my sticky fingers.
My sister took her sperm-y hand and licked it.  I took her hint and tasted
her own liquid from my fingers.  It was tart, salty, strange, but also
quite alluring. I'm tasting my sister's pussy, I thought to myself, and it
made me feel wrong and that, in turn, just turned me on again.  God, I was
so broken.

   I looked over at the woman who'd wrecked me, my own sister.  She was
stretching languid on the bed like a cat after a bowl of milk.

   "I came a little," she told me, "Don't worry, you'll get way better. 
This is important stuff.  You're getting older, meeting real women, you
need to know how to get them off.  I'm just happy I can be here to teach
you."

   "Thanks Darcy," I said.  I was doing that a lot.  Thanking my sister for
something I wasn't sure I wanted her to give me in the first place.

   "That's what big sisters are for," Darcy said.  She rubbed my head and
went to take a shower.  I tried to follow her, but my sister made it clear
that this would be a solo exercise.

   "Mom and Dad are both home," she said, "I don't want to take any more
risks than we already have.  You'll go after me."

   When Darcy was done, she pushed me back into the bathroom.  I didn't
usually shower more than twice a week at most, but my sister insisted that
I needed to clean off.  While I soaped myself, I smelled my fingers again.
My sister's scent became more pleasant, more exciting, with every sniff.

   *

   After the shower, I got dressed and went downstairs.  My mother was in
the kitchen, cleaning up after breakfast.  My father had run out to get
supplies.  They were going to spend the whole Saturday gardening in the
front yard.

   "We'll plant flowers, put in some stakes for the tomatoes, trim back the
bushes," my mom said, "You sure you don't want to join us?"

   I told her no, then heated up a pop tart in the toaster.  By the time it
was done, Darcy came down.  She was wearing a baby blue tank top and a pair
of black yoga pants.  Her hair was up in the usual ponytail.  She looked
like a woman going to work out or laze around the house.  She looked
amazing.

   "E and I are going to hang out all day," Darcy told my mother, "Get some
good sibling bonding time in."

   My mother tried to explain that we could have good sibling bonding time
by helping out around the house, but Darcy wasn't hearing it.  Eventually,
she drowned Mom out with the sound of the blender as she made herself a
smoothie.

   "We're going to a movie," Darcy said, more of a command than a
suggestion.

   My older sister led me out to her car.  Even though Darcy was working a
high-powered finance job, she still had college graduate money and her car
was proof of that.  It was a cherry red VW Jetta, one of the boxy ones,
with at least 15 years and over six figures of experience on it.  For a
woman Darcy's age, the car was relatively clean, which meant that it was
pretty damn dirty in the aggregate.

   The movie theater was over by the mall, but Darcy drove us downtown
instead.  I had my license, but the Jetta was a stick and I'd only learned
on my Dad's automatic.  Not that I thought my sister was going to let me
drive her car, even if I could.  Remember, she didn't even trust me to jack
my own dick.

   "We need to stop for something before we can see the movie," my sister
explained.

   We parked in front of the local barber shop.  Darcy fed the meter and
took me inside.  There was already a line of at least ten dudes.  My sister
was the only woman in the place.  We found two open chairs and waited.  I
found a Maxim magazine and learned all about how Jessica Alba likes to
please her man.

   Finally, one of the barbers called out that it was my turn.  He was an
older gentleman, wearing a plain white dress shirt with his name stitched
into the breast, and black slacks.  He smelled heavily of pomade.

   "Just a trim," I said, asking for my usual

   "Shave it all down," Darcy corrected me.  The barber looked at both of
us, like trying to decide who truly had the authority here.  I don't need
to tell you who won.

   I watched in the mirror in horror as the barber slaughtered my curls.  I
never liked my hair, it was way too unruly.  But it had become a part of my
identity over the years and seeing it clipped away was like watching a
piece of my personality getting shorn off.

   By the time the barber was done, my hair was cropped close on the sides.
He'd let it stay a little thicker at the top, but my curls were gone.  I
looked in the mirror and, dammit, Darcy was right.

   "Looking good," Darcy said.  She slapped my ass when I stepped out of
the barber's chair.  "Now we can head out for our day."

   *

   Darcy drove us down the highway to the multiplex over by the mall.

   "So, what are we going to see?" I asked as we accelarated.  Darcy gave
me a confused look in return, like I'd asked her something ridiculous.

   We parked by the theater and walked up to the window.  Darcy picked a
movie that was starting in five minutes, some dumb action thing I doubted
she could have much interest in.  She bought us a bucket of popcorn,
slathered it in fake butter at the self-serve, grabbed a handful of
napkins, and led me into the theater.  The previews were starting.

   It was a Saturday at 10am and this movie had not done well.  The
auditorium was only ten rows, stacked stadium style, and almost completely
empty.  An older couple was parked up in the second row on the far side,
but that was it.  Darcy walked up the steps and sat down in the back row on
the far side.  She patted the seat next to her with a grin.

   We watched the previews in silence.  The theater went dark as the proper
picture started.  Darcy's hand landed right in my crotch.

   I looked up at her in surprise.  My sister unbuckled my belt, unzipped
my jeans, and pulled out my dick, right there in the theater.

   "Darcy!" I almost shouted it and I got a proper shushing from the older
couple up front..

   Darcy's hand was slippery from the popcorn 'butter' and she began
stroking my cock.  I was already half hard and she got me the rest of the
way there.  Then she stopped.

   My older sister nodded expectantly at me, using her head to point my
eyes over to her seat.  Darcy had her legs spread as wide as they could go.
She gave me a suggestive smile.

   I was already uncomfortable having my own sex out at the theater, but
apparently Darcy needed me to do the same for her.  I reached across the
armrest and unbuttoned my sister's jeans.  She lifted up her butt to let me
pull down her pants and panties.  Her hairless pussy was now bare on the
movie theater seat.

   I slipped my finger into my sister and she resumed stroking my cock. 
Darcy took a long, slow approach.  Sometimes she would tease me to the
edge, then pull me back.  Others she would lightly trace and tease.  I was
in a constant state of near-orgasm.

   For myself, I lacked the skill to do the same for Darcy.  The first time
she came, it was a little one.  Her hips tightened and she let out a little
gasp.  I wouldn't even have known it happened except she leaned over and
told me.

   "You made me cum," Darcy whispered in my ear, "You made your big sister
cum in a movie theater."

   She settled in and we both got back to stroking.  The next time was more
obvious.  Darcy's hand shot down and held my wrist in place.

   "Ah," she gasped, "AH!" Her whole body stiffened, then wriggled.  Even
in the dark, I could see her face flush.

   Now it was a challenge.  Seeing Darcy screwed up in pleasure like that
was awesome and I wanted to watch it again.  But try as I might, I couldn't
get her back to that height.  I managed to drag a few smaller cums out of
her, I recognized them now, but nothing more.

   Then, with the final car chase on screen, Darcy pushed my hands out of
her pussy.

   "Time for the big finish," my sister told me.  She leaned over the
armrest and swallowed as much of my cock as she could.  I'd already been
building for two hours, it wasn't going to take much effort.

   When I came, it exploded out of me, bubbling and burbling like an open
fire hydrant.  One large blast and then one after the other.  I felt like I
wouldn't ever stop cumming but, slowly, I did.  Darcy popped off my cock,
showed me how full her mouth was, and swallowed.  Then she took a big
handful of popcorn and chased my semen with it.  She gave me a big,
happy-cat smile.

   As the credits came on screen, my sister pulled up her pants.  I did the
same.  We left the half-eaten bucket of popcorn behind and walked down the
steps.  Before we could leave, a theater employee caught my arm.  He was
middle aged, round around the middle, with nothing but a few brown wisps of
hair at the top.  His nametag said, I kid you not, Rod.

   "I got a complaint that you two were acting inappropriately in there,"
he said.

   "Those old bastards," Darcy said.

   "I can't tell you who it was," Rod said.

   "They were the only other people in the theater," Darcy said.

   "In any case, they claimed they heard you doing," and here Rod got
nervous, "dirty stuff."

   "This is my brother!" Darcy screamed, "Are you implying what I think you
are?!" She grabbed my elbow protectively and, ironically, painfully.

   "Um, no ma'am," Rod said.  He seemed to be shrinking with every second.

   "Are you accusing me of committing...  I can't even say the word!  Is
that what you're actually doing?" Darcy was loud enough that other people
were looking over at us now.

   "I'm sorry ma'am," Rod said, "They must have been mistaken."

   "Fuck right!" Darcy said, then stormed out of the theater, dragging me
in tow.  As soon as the doors hissed behind us, my sister started cackling
madly.

   I couldn't do the same.  I was mortified.  But she seemed to think it
was all a big joke and told me I was being silly for thinking anything
otherwise.

   "Come on, I want to go shopping," Darcy said, once her laughter had died
down.  We marched across the parking lot and up to the mall.

   It was afternoon now, and the shopping center was fairly crowded.  There
was a Chipotle in the food court and we both got burrito bowls for lunch.

   "I hate this fucking place," Darcy said as we ate.  We were sitting on
tiny chairs in the middle of an ocean of small tables .  It was loud, full
of surly teenagers and wild children.

   "Why did we come here then?" I asked.

   "Something to do," Darcy said, "Get out of the house.  Not get stuck
gardening or whatever.  There's nothing to do here.  This mall, this
town, this fucking state.  I hate all of it."

   "Why'd you come back?" I asked.

   "Don't sound too disappointed, brother," Darcy said.  She reached across
the table and took a handful of my chips.

   "No, I'm glad you're home," I said.  I saw my sister's dubious look, "I
really am.  And not only for the, you know, other stuff.  But you seem so
unhappy."

   "It was come back home or move in with, like, six other women in a
crappy studio apartment," Darcy said, "You don't get it.  You're still
fucking around." She waved her hand as she said that, a kind of upward
twirl that, apparently, meant 'fucking around.' "But life, once you have a
real one, it's not about making good choices.  Just taking the least bad
one."

   "Don't sound too disappointed, sis," I said to her.  I stole one of my
chips back from her pile.

   Darcy leaned over the table kissed my forehead.  "You're the best thing
I've got going, E.  Don't you worry."

   After we ate, we walked around the mall.  I assumed we would look for
clothes for my sister, but she plowed past every women's store, even the
shoes.  Instead, we stopped at a place with men's clothes.  Darcy dragged
me inside.  She picked out bright colored dress shirts and dark slacks,
things I would never wear, and made me try them on.  When I was done, she
picked three shirt and pant combos and brought them up to the register.

   "That will be $151," the cashier said.  He was a short, trim man with
perfectly manicured fingernails.  Darcy looked at me, expectantly.

   "I don't have that kind of money," I said, "Especially not for clothes I
won't even wear."

   "Yes, you do, and yes, you will," Darcy said.  She had on her 'you will
get this blowjob and like it' face.  I knew better than to argue with her.
I didn't have a lot of money, only a small bit of savings I'd squirrelled
over the years.  Maybe five grand in total.  I had a sinking feeling it
wasn't going to be mine much longer.

   "This is a great deal," Darcy said, "You'll be paying twice that at
other places."

   The cashier nodded enthusiastically in agreement.  I sighed, but I took
out my debit card and let the guy run it.  He gave me back my card and a
bag of clothes, neatly folded.

   We did that at three other stores.  Darcy picked out very professional
looking outfits - dress shirts and polos, khakis and slacks - and made me
pay for them.  After a couple hours, I was laden down like a teenage girl
on a shopping spree.  The only thing I had on me that was light was my
newly denuded savings account.  Darcy led me through the mall like she was
my shopping Sherpa.

   "One last place," Darcy said, and I said a silent prayer that it wasn't
a jewelry store.  Instead we stopped in front of a lingerie shop.  My
sister gave me a wicked smirk and went inside.

   The store wasn't the typical mall brand you're probably thinking of,
though it might as well have been for all they'd cribbed from their more
common competitor.  Darcy went through like she'd planned it all
beforehand, pulling down panties, bras, and other assorted items, and
marched to the changing rooms in the back.

   "Wait here," she told me.  I was very relieved when she said it.  Our
earlier close call at the movie theater had been enough excitement for me.
I found a small stool nearby and sat down.  The store wasn't busy, but it
wasn't well staffed, either.  There was an employee over by the registers,
but that seemed to be it.

   As soon as I got comfortable, Darcy skipped out of the back area.  She
was wearing a dark green silky slip with a plunging neckline.  She modeled
it for me, doing a little spin.  The outfit wasn't so revealing, but it
still felt strange to see my sister in it, showing off in public.

   "Well?" she asked, hands on her hips.  Apparently, I'd spaced out a
little.  I wasn't sure what to say, to be honest.  Did she look hot in it?
Absolutely.  Was I, her brother, supposed to find her hot?  That I was less
sure about.  Who was she trying these on for, anyway?  For a future
boyfriend?  It couldn't possibly be for me.

   "You look nice," I said.  Darcy made a frustrated grunt and stormed back
to the changing rooms.

   She came back out in a matching pink cami and shorts set.  Again, my
sister twirled for me.  She looked good.  Was I supposed to tell her she
looked good?  Mostly I wanted to get this over with.  Being caught in the
lingerie store with an erection over my sister seemed like a bad idea

   "Very sexy," I said.  Darcy shook her head at me and went back.  She
took a much longer time.  I kept glancing over at the registers, but no one
noticed us.  Maybe we would be OK.  What was wrong with trying on stuff,
right?  And Darcy and I didn't look so similar.  I could be her younger
boyfriend.  I'm sure this happened all the time.  But I kept looking over,
nervously.

   Just as I was about to finally relax and pull out my phone, Darcy
sauntered out.  She was wearing a fire engine red teddy this time, pushing
up her already prominent breasts and cut so tight at the crotch I could see
her pussy pressing through.

   "Wow," I said.  I hadn't even intended to speak.  It dropped out of me.
Darcy turned to show me her backside and I said it again.  "Wow."

   My sister didn't say anything, but she smiled big and blushed almost as
scarlet as the outfit she was wearing.  She ran back to the changing rooms.
The outfits were getting smaller and smaller.  Was she really going to come
out wearing less?

   Instead Darcy popped out less than a minute later, wearing the exact
same outfit as before.

   "No cameras," she hissed happily, then took my hand and led me back. 
This seemed like a tremendously bad idea, but my sister wouldn't let me
argue.  Instead we went into one of the changing rooms.  I saw Darcy's
clothes piled in the corner.

   My sister pushed me back against the wall.  She dropped to her knees,
taking my pants and underwear with her.  Before I could protest, my penis
was in her mouth.

   This was more like the standard Darcy blowjob.  Fast and hungry.  She
slurped up and down my dick like she'd been poisoned and my cum was the
only antidote.  It didn't take much for me to be close.

   I heard a set of footsteps heading our way.

   "Oh God," I said.

   "You close, baby?" Darcy asked.

   My whole body froze.  My older sister kept sucking.  The footsteps got
softer as they went in the other direction.  Either we were totally safe,
or someone was heading off to call the cops.  There was no in between.

   I was so worried, my cock actually started to soften, but my older
sister wouldn't take no for an answer.  She redoubled her efforts, rolling
my balls in her fingers and pumping me with her fist.  That got me back up
right quick.  A moment later and Darcy was making her trademark swallowing
sounds as she digested my seed, spurt by spurt.

   Gulp.  Gulp.  Gulp.

   She looked up at me with a supplicant smile, then stood.

   "Better?" Darcy asked, as if I was the one who'd demanded she do this in
the first place.  I couldn't speak, so I nodded.  "Good.  Go back so I can
get changed."

   A few minutes later, Darcy came out wearing her yoga pants and tank top.
She was holding the red teddy in her hands, but everything else had been
left behind.  She was about to head up to the register, when I noticed a
streak of my cum was still on her chin.

   "Oops!" Darcy said, "Thanks, E.  That would have been embarrassing." She
quickly wiped her face with her hand, then brought the teddy up to pay.

   "Did you find everything you needed?" the cashier asked.  She was
blonde, petite, and very pretty.  Her nametag said, I kid you not,
Victoria. I couldn't meet her eyes.  Suddenly, the fake wood floors were
the most interesting thing in the world.

   "And then some," Darcy said.

   "Your, um, friend got what he needed, too?" Victoria asked, eyeing me.
She said the word 'friend' in a hopeful way.  Like she didn't want Darcy to
correct her.

   My sister elbowed me in the ribs so I would respond.

   "Um, yeah.  I mean, yes," I said, "Thank you."

   "Next time let me know.  I'm always here to help.  You know, special
requests," Victoria said.  She looked right at me when she said it.  Then
she and Darcy shared a wicked grin.

   Again, Darcy made me pay for the clothing.  "To thank me for all the
nice things I do for you," she explained.  I didn't even bother to argue.

   When we left the store, Darcy reached into the bag and showed me the
back of the receipt.  Victoria had written her phone number there with the
words, 'Call me.'

   *

   We walked around the mall a little more, but when I found the video game
store, Darcy announced it was time to go home.  We went out to the parking
lot and found her red Jetta.

   "I'm really tired," Darcy said, giving me a big yawn while she tossed
our bags in the trunk.  "Drive us home, kay?"

   She handed me the keys.  They felt oddly heavy in my hands.

   "What's the matter?" Darcy asked, "You have your license, right?"

   "I can't drive stick," I told her, sadly.

   "Psh, it's easy," Darcy said, "You'll learn it in like, five minutes,
tops."

   She pushed me into the driver's seat and climbed in on the other side.
In a tone that was oddly reminiscent of my lessons from earlier that
morning, Darcy explained to me how to drive a car with three pedals.  Then
she patted my head and gestured for me to go.

   I got it started OK, but when I tried to accelerate forward, the car
juddered violently and stalled.  I gave my sister a helpless look, but
Darcy pursed her lips and gestured for me to try again.

   On the third attempt, I got the car out of the space.  Once it was
going, it was easier to shift into second, then third.  Then we got to a
stop sign.  I wanted to roll it, but there was a car in the other
direction, so I stopped fully.

   Again, when I tried to start, Darcy's Jetta cut out.  I swear, I could
feel the car's hatred of me, just begging to go back to its real owner.

   Darcy showed me no mercy though.  With a line of cars behind me honking
like crazy, I was finally able to get us moving again.  I said a prayer to
the driving gods for no more stops the rest of the way home.

   We hit three more stoplights (I stalled each time), but finally got on
the highway.  I shifted into fourth.  This was more like the driving I was
used to.  I realized my muscles were stiff - my biceps and thighs - like
I'd just done three hours of CrossFit.

   Darcy's phone started to sing, but she switched it off.  Then she
reached across the seat and started undoing my belt.

   "Um, Darcy?"

   "It's BJ o'clock," Darcy said, like this was totally normal.  I had
finally stopped freaking out in the car, but it started all over again as
my sister fished my dick out of my fly.  "Every two hours."

   "You have an alarm set?"

   Darcy shrugged like it was the most natural thing in the world.  She
dipped over and started sucking my dick.  That traitorous bastard stiffened
right up as she slurped up and down.

   "I don't think this is a good idea," I said.

   "Then hurry up and cum," Darcy said.

   A truck honked loudly, and I realized I'd swerved halfway out of my
lane. I did my best to straighten up, but I could either focus on the road
or my sister's blowjob and doing both was going to get us killed.

   We came up on our exit and I signaled over.  My sister hummed over my
dick.

   "Come on, little brother.  Be a good boy and give me all your cum,"
Darcy said.  She sat up, looked around, quickly flashed me, then dropped
back down on my cock.  She made happy little humming noises, like she was
eating the world's best burrito instead of her brother's dong.

   We got off the highway and stopped at a red light.  I prayed no one
would pull up next to us, or behind us, or anywhere.  Finally stopped, I
was able to give Darcy my full attention.

   "Here, hold my head," Darcy said, taking my hand and putting it on the
back of her skull.  "Like a good slut."

   I rested my hand there, but I didn't push.  Darcy did all the work
herself.  Right as the light turned green, I came.

   Gulp.  Gulp.  Gulp.

   My world went white as I filled my sister's waiting mouth.  The pleasure
was intense but short.  The next thing I knew, I was being treated to
another symphony of car horns.  I hit the gas and, of course, stalled.  By
the time I was able to get started, the light had turned red again.  As you
can imagine, the traffic around us was not happy with me.

   "Here, I'll take us home," Darcy said.  She jumped out of the passenger
seat and ran around the front of the car, waving apologetically to all the
other drivers.  I climbed into the passenger seat and my sister took the
wheel.  When the light turned green, we raced off with a roar.  Darcy
laughed hysterically as we peeled off.

   *

   "How was the movie?" my Mom asked as we got out of the car.  She and Dad
were both on their hands and knees in the front yard, putting in tulip
bulbs.

   "Good," Darcy said, "We went to the mall after and hung out.  Ethan
bought a bunch of clothes for work."

   "No, I..."

   "Oh, I'm so glad to hear that," Mom said.

   "Happy to see you're finally taking things seriously," Dad said.

   "I like the haircut," Mom said, "Very dashing."

   "I need a nap," Darcy said, then went into the house.  I shrugged and
followed her inside.  My sister wasn't kidding.  She went right to her room
and shut the door behind her.  I stood, staring at the wood grain dumbly
for a moment, then went back to my own room.  I took out all the clothes
Darcy had made me buy and put them in my drawers.  They looked odd lying
next to my t-shirts and jeans, like a dude wearing a tuxedo at a swimming
pool.

   An hour later, my parents came in the house.  I heard them taking turns
showering and working on dinner.  They called us down and the four of us
ate together at the table for the first time I could remember in years.

   After dinner, my parents announced that since they had cooked, it was
Darcy's and my job to do the dishes.  We both stood up and started
clearing. Darcy started the sink going and I stood next to her, towel at
the ready, to dry.

   Instead of handing me a dish, though, Darcy stood in front of me and
undid her jeans.  My eyes nearly popped out of my head.

   "Come on, E, I'm so worked up from today.  I did you twice in a row with
nothing in return," she said.

   I agreed that was fair, but I didn't think it was such a good idea to do
it now, with our parents in the next room.  Darcy wouldn't hear it though.
She let her bottoms fall to her ankles and turned around.  Bent over the
sink, doing dishes like it was nothing.  Like her pouting, purple pussy
wasn't being presented to the world right that moment.

   "The sooner I cum..." she said.

   I reached down around her ass and found her wanting slot.  I dipped my
fingers into my sister's sex, and she gasped.

   "You OK in there?" my Mom called out.

   "Water.  Hot," Darcy said.  She was down to one word at a time.  I
started sawing in and out of my sister's sex.  She wiggled her butt and
giggled.  She took one hand out of the sink and started to rub her clit. 
We worked together to bring her off.  The kitchen started to smell of my
sister.  I was praying to a lot of different gods that day, but whoever
oversaw parental distraction was definitely at the top of my list in that
moment.

   Finally, Darcy stiffened.  Her eyes rolled back a bit and her hand
stopped stroking her clit.  I slid my fingers out of her.

   Darcy reached down and pulled up her pants.  She started washing the
dishes more quickly.  But she looked right at me, expectantly.  I put my
cunt-covered fingers in my mouth and sucked.  I was getting more
comfortable with the flavor of my sister's sex.

   She laughed.  "I meant I need you to dry," Darcy said, nodding over at
the dishtowel.  "But that's nice, too."

   After we were done, Darcy went right up to her bedroom.  I was exhausted
from the day, so I followed her up and lay down in my own bed.  I picked up
my iPad to read myself to sleep.  I thought it was over, but then I heard
Darcy's phone ringing distantly.  A moment later, my door popped open and
Darcy slipped inside.  Her hair was up and off to the side, clearly
unsettled by sleep.

   My older sister yawned, pulled off my covers, gave me a quick BJ, then
left the room.  It was the most clinical sexual experience I'd ever had.  I
fell asleep soon afterwards.

   *

   I woke up to the usual sight of my sister, but she wasn't dressed in her
usual tank and panties.  Instead, she was wearing tight dark shorts and a
pink t-shirt.  She stood at the end of my bed and started to stretch.

   "Come on, bro, day's waiting," Darcy said.  I looked over at my phone.
It was 6am.  Even my parents would be dead asleep at this hour.

   "Don't care," Darcy said, "Time to go."

   I sighed and stripped off my pants.  My cock lolled lazily on my leg.

   "Not that!" Darcy said.  "That's for later.  Exercise first."

   I groaned and got up.  I saw Darcy had already gone through my clothes
and laid out a pair of shorts and a t-shirt for me, plus my socks and
sneakers.  I got dressed, unsure if I was awake or dreaming.  Then my
sister dragged me outside.

   "We'll start slow," Darcy said and took off.  I tried to keep up with
her as best I could.  Like I said, I wasn't in bad shape, but I wasn't
running every day (or every month) either.  After the first ten minutes, I
started panting.  After the first twenty, I started dying.  But Darcy
wouldn't let me stop.

   Finally, after we'd gone around the block about four times, my sister
stopped in front of the house.  I stood over our newly planted tulip bulbs
and retched.  Darcy stood next to me, bouncing happily on her heels.

   "We're doing this every day from now on," Darcy said, "It's part of our
routine."

   I nodded, defeated.  I limped up the stairs and into the shower.  Darcy
showered after me.  When she was done, she came into my bedroom wearing a
tank top and yoga pants, her hair up in cute girlie pigtails.

   My sister pulled me to the edge of the bed, then knelt in front of me.
She didn't even say a word, just sucked me off.  It was another one of
Darcy's weekend morning blowjobs, slow and sensuous, teasing and taut, till
finally I emptied myself into her waiting mouth.

   Darcy gulped it all down, then clapped her hands and jumped onto my bed.

   "My turn!" she announced and stripped off her bottoms.  She spread her
legs lewdly and lay back.

   I reached over to touch my sister's quim, but she pushed my hand away.

   "I think you've gotten enough oral to return the favor," Darcy said.  I
nodded.  She was right, of course.  I climbed between my sister's legs and
put my head up to her sex.  I could smell her from the source this time and
it was stronger, heady.  Yet also disturbingly familiar.  I wasn't supposed
to know this scent, and for a moment the old feelings of wrongness roiled
in my stomach.  I pushed them back down.

   Tentatively, I licked at my sister's pussy.

   "Not this again," Darcy said.  She sat up slightly and made sure I was
listening.  "You're eating my pussy, not painting the Sistine Chapel. 
Whatever you do with your fingers, do that.  But with your tongue."

   I went deeper and licked my sister, hard, from top to bottom.  I sucked
on her clit and tried to rub it back and forth with the flat of my tongue.
When I rolled up my tongue and slid it into her hole, Darcy jumped up like
she'd been shocked.

   Now, not only was I smelling my sister, but I was tasting her.  And, to
my shock, I found I kind of liked it.  I liked the way she responded to me
licking her even more.  I got a rhythm going.  Like my sister did to me, I
used my fingers and mouth to get her off.

   I'd been rubbing Darcy's clit with my tongue and pumping her with my
fingers for a while when suddenly my sister grabbed the back of my head and
held me there.  Her thighs closed around my skull so hard I thought she
might crush it like a grape.  Distant, through her thighs, I heard Darcy
scream.  Then she fell back, limp and weak.  I gave her pussy one last
little kiss and her body trembled.

   Watching my sister's orgasm was the sexiest thing I'd ever seen.  Full
stop.  Not sexy for my sister, as so many things had been before.  But
actually, totally hot in a way that no porn video could ever compare.

   I realized that, up till then, I hadn't actually made my sister cum. 
Not really.  Just little bursts of pleasure.  This time though, Darcy
actually did go over the top.  She lay back, distant, and stared up at the
ceiling.  She mumbled to herself and stroked my head.  Otherwise she didn't
move.

   "Thank you, Ethan," I heard her say.  That same strange, plaintive
appreciation I'd given her before.

   Gradually, Darcy rolled out of my bed.  She pulled her bottoms on and
got up to go.  Her legs gave out, but then she stood up straight and
stumbled out of the room.  I got up as well, my face sticky with my
sister's spend.

   When I came downstairs, Darcy was sitting at the kitchen table, staring
at her phone.  Our parents, miraculously, were still asleep.  Thank God for
lazy Sundays.

   "You should make breakfast," Darcy said, looking up from her screen.

   "I think I know how to make cereal," I said.

   "Pancakes," Darcy said, "With bacon."

   I gave her a confused look.

   "There's this new thing called the Internet.  Look it up and get to
work."

   I nodded, exasperated, and went into the kitchen.  There was an easy
recipe online and I realized we had enough in the house for me to make it.
I burned the fuck out of my first pancake and none of them came out in a
Euclidean shape, but by the time my parents came downstairs I'd put
together a whole, mostly edible breakfast for the family.  I even warmed
the syrup and filled little glasses of orange juice.

   "Wow, what's this for?" Dad asked as he sat down, eyeing the food warily
like he expected it to melt into a mirage at any moment.

   "Ethan wanted to thank you guys for putting him up for free all summer,"
Darcy said.

   "I did," I said.

   "He appreciates how much you both sacrifice for him," Darcy said.

   "I do," I said.

   "In fact, he's going to be making meals for all of us from now on,"
Darcy said.

   "I am?" I asked.  My sister gave me an ugly glare.  "I mean, I am."

   "We all work hard during the day, but since Ethan's at home it makes
sense for him to be doing the cooking," Darcy said, "Right?"

   "Ummm, yes."

   "At least until he gets a summer job," Darcy said.

   "Well I must say I'm very excited about this new attitude from you,
Ethan," Mom said.

   "You know we love you no matter what," Dad said, "But we're proud that
you're finally helping out with the family."

   "I don't suppose you're going to help us with the gardening," Mom said,
"As part of your newfound responsibility."

   Darcy rolled her eyes.  "We have important stuff to do today," she said,
ignoring Mom's glare.

   After breakfast, I did the dishes and went up to my room.  The morning
had been so crazy, I wanted to pack a bowl and play games.  But I found
Darcy in my bedroom.  She was sitting on my bed, supplicant.  I sighed and
started to strip off my pants.

   "Not yet," Darcy said.  "First, this place needs cleaned."

   I picked up all my laundry and put it in the basket.  I emptied my
tissue-filled trash can and sprayed out liberal amounts of Febreze.  I
cleaned off the tops of my furniture and made my bed.  In the process, I
uncovered parts of my carpeting that I hadn't seen in years.  All while my
sister sat there and watched.

   When Darcy was satisfied, she stood up and dug into my desk.  She held
up a large sheaf of papers, triumphantly.  Even though they'd been buried
in the bottom of my desk drawer for months, I recognized them immediately.
"You're going to fill these."

   "I don't even know if I want to go to college," I said, a whine creeping
into my voice.

   "I don't know why you think I even care," Darcy said.  She got up and
slapped the papers down on my desk.  "You have a scholarship.  Do you know
how many kids would kill for that?"

   "I'm tired of school," I said, "I want to be, like, free for a while."

   "You mean freeload off Mom and Dad," Darcy said.  "Look, you may not see
it now, but there's going to be a time you wished you did this only it'll
be too late.  Trust me, you're filling this out now."

   "Can I at least smoke up before I do it?" I asked.  Darcy gave me a
dirty look.

   I sat down at my desk and flipped over the first sheet.  I took a pen
and started to fill it out.

   "I don't know why this isn't electronic," I said.

   Darcy shook her head.  As I started to write, she climbed under my desk
and buried her head between my legs.  Before I finished putting our home
address down, my dick was deep down my sister's throat.

   Darcy took her time, coaxing my cum out of me.  She suckled happily and
only slowed if she felt like I wasn't doing the work fast enough.  Finally,
as I finished the last bit of paperwork, my sister finished me off.  By
that time, it was almost more of a relief to cum than a pleasure.

   Darcy slipped out from under my desk and kissed my forehead.  She took
the pile of finished paperwork, and then dropped it in an envelope. 
Apparently, I'd decided it was time to go to school.

   *

   That night, after dinner, my parents announced that they were going to
watch TV and invited us to join.  My Dad turned on some nature documentary
and joined Mom on the couch.  There was a big leather recliner off to the
side, so I sat down on that.

   "Cuddle time!" my sister cried out, then jumped onto my lap.  My parents
laughed as my sister snuggled over me, kissing my cheek for good measure.

   "I like that the two of you are getting along," Dad said.

   "I missed my little brother while I was at school," Darcy said.

   "Could've fooled me," I heard my Mom grumble, but no one else said
anything.

   Darcy reached over for a blanket and pulled it on top of us.  She
shifted, then settled, until her warm center was right over my dick.  I got
hard as a rock.  I was eighteen, and my dumb cock didn't know it wasn't
supposed to be erect after already cumming three times that day (the after
jog blowjob, the college application oral, plus a quick handy in my bedroom
before Darcy sent me down to make dinner).  My dick was ready for more fun.
Poking upward right into my sister's crotch.

   Darcy ground her puss down, clearly feeling the stimulation.  She
started rocking back and forth on my dick.

   "You comfortable over there?" my Dad asked, "There's space on the
couch."

   "Fine..." Darcy mumbled.  I noticed her face was pinkish, her lip was
trembling, and a thin sheen of sweat ran down her cheek.

   "OK," my Dad said, as if this was totally normal.

   My sister kept grinding down on my dick.  It didn't feel good to me,
through both our layers of clothes, but Darcy was having a different
experience.  She was breathing heavily.  Not even trying to hide that she
was humping up and down on her little brother.

   Suddenly, she stopped.  "Gotta go," she announced and leapt off my lap.
She scampered up the stairs and shut her door, loudly.

   "Gee, I hope her stomach isn't acting up," my Mom said absently, "While
I appreciate you making us chicken tonight, Ethan, it did seem a little on
the pinkish side."

   After the show was over, I got off the lounge chair and went upstairs.
Darcy's door was shut, and I didn't want to disturb her.  I washed up, then
went to my own bedroom.

   I nearly jumped out of my skin when I opened the door and found my
sister lying back on my bed.  She was in a matching pair of green underwear
and reading one of my comic books.

   "Took you long enough," Darcy said.  I shut the door behind me,
carefully.  We'd done so good to survive so far; I didn't want to get
caught now.

   "Sorry, I didn't want to set off Mom and Dad," I said.

   Darcy tossed the comic book to the side and slipped off her panties. 
She spread her legs.  I saw her thighs were shiny with her own lubrication.
I already knew what I was supposed to do, and I lapped hungrily at my
sister's snatch.

   This time, I had a good idea of what worked and what didn't.  I spent a
lot of time bathing my sister's clit before finally filling her sex with my
fingers.  Darcy didn't take nearly as long as that morning either,
clenching her legs around me and screaming, "oh FUCK!"

   "You two OK up there?" my parents yelled up.

   Darcy gasped, then giggled.  I looked up and saw her arched upwards, her
face bright red.  Mine felt just as cherry from being suffocated by my own
sister's pussy.

   "Fine!" Darcy yelled.  "Stubbed.  My toe." She was barely able to speak
as the pleasure raced out of her.  Finally, she fell back into the bed and
started giggling again.  "That was fun!" she told me.

   Of course, now I was so hard you'd think I hadn't been touched in months
rather than hours.  Darcy sat up and gave me a vigorous hand job.  When I
was close to cumming, she put me in her mouth and swallowed me down.

   "That was excellent," Darcy said, and I didn't know if she meant what
I'd done to her or what I'd put down her throat.  Maybe a bit of both.

   My sister kissed me on the cheek, then went off to bed.  Practically
skipping across the hallway.

   *

   Monday morning, I got the usual early wakeup from my sister.  Not even
the sun was up when she dragged me out of bed.  We ran again and, if
anything, this felt even worse.  Now, not only was I tired, but my muscles
hurt from the day before.

   "It gets easier the more you do it," Darcy said, "Like a lot of things."
She gave me a wink.

   When we got home, Darcy dragged me around the side of the house and
dropped to her knees.  We were surrounded by fencing, sure, but it was
still very exposed.  A neighbor could have stopped by any second.  Worse,
we were right under my parent's bedroom window.  But Darcy slurped me down
until I came down her throat.  Then we went inside the house and showered
separately.

   When I was done, I went back into my bedroom and lay down.  I have to
admit, I was looking forward to having the house to myself again.  I'd
grown to enjoy the sexy stuff with my sister, sure, but she was starting to
wear me out.  I stretched out on the bed, thinking I'd nap for a few hours
before smoking up and getting down to some serious gaming time.

   My bedroom door popped open.  I nearly fell out of the bed.  Darcy had
on a deep purple blouse and a slate grey skirt.

   "Hurry up and get dressed, bro!" Darcy said.  I had on a t-shirt and
boxers, as far as I was concerned, I was dressed enough.  Darcy groaned and
dragged me out of bed.

   "No, come on, real clothes.  Why do you think I took you shopping this
weekend?"

   Darcy stood and watched while I put on a sky-blue dress shirt and
charcoal slacks.  Then we went downstairs, and she made each of us a
smoothie.

   "I hope you watched how I did that, because this is going to be your job
from now on," she told me as she handed me a cup full of pureed green
liquid.  I barely had a chance to sip it before my sister pulled me down to
the driveway.  I had a momentary heart attack thinking she was going to
make me drive, but instead Darcy jumped behind the wheel.  I climbed in on
the other side.

   "You're going to do great," Darcy told me as we pulled onto the highway.

   "At what?" I asked, but Darcy just turned up the tunes.  Her car was so
old, the only option was terrestrial radio, but she seemed to enjoy it.

   Eventually, we got off the highway and pulled into the busy city
streets. Darcy navigated confidently through the gridlock and pulled into
an underground garage beneath a row of tall, mostly glass buildings.  Once
we were parked, Darcy grabbed her bag and her brother, then went to an
elevator bank on the far wall.

   The lobby was huge, airy, and made mostly of marble.  Darcy showed an ID
badge to a security guard and had me sign in.  We went over and got in
another elevator with a bunch of other people dressed as professionally as
my sister.  We got off on the fourth floor.  Darcy threw her bag down in a
tiny cube office at the back of a whole sea of them.  Then we marched off
again.

   The cube sea was surrounded by small offices with glass doors.  Most of
them were empty at this hour, but Darcy took me to one with an older
gentleman sitting in it.  He had on a blue, pinstriped shirt with navy
suspenders.  His full bristle mustache was grey.  He looked like he'd
escaped from the set of Mad Men.  His name was, I kid you not, Mr.  Cox.

   "This is my brother," Darcy said, poking her head in the door.  "He's
here about the internship?"

   Mr.  Cox invited us into his office.  We both sat down in flimsy chairs
facing his desk.

   "So why do you want to come work for us?" Mr.  Cox asked me, leaning
forward on his elbows and studying me like I was a newly discovered life
form.

   I froze.  I didn't even know what job I was interviewing for, let alone
why I wanted it.  In fact, I didn't want a job.  I wanted to be home, in
bed, half-stoned and fully immersed in video games.  But here I was in
these itchy pants and suffocating shirt and my sister was glaring me down
the longer I took to answer.

   "I, um, I'm looking for the experience?" I said.  I saw Darcy nod
appreciatively out of the corner of my eye.

   Mr.  Cox asked me a bunch more questions about myself.  He frowned at my
lack of work experience, but that went away as soon as Darcy mentioned I
had a scholarship for college.

   "Oh, that's right down the street from here," Mr.  Cox cooed.

   "Yes, Ethan's hoping he can keep interning here in his free time while
he goes to classes," Darcy said, "He's excited for the opportunity."

   Mr.  Cox asked me a few more questions, then explained that I'd be
starting in the mailroom.  "Yes, even these days, you'd be surprised at the
amount of paper correspondence we get that needs to be sorted and delivered
over all ten floors.  You'll be here from 8am till 2pm every day, starting
tomorrow."

   "I'll drive him in," Darcy said.

   "Excellent," Mr.  Cox said.  It was very clear that it was time to go.
We stood up.  Mr.  Cox shook my hand.  "You can call me Randy," he said. 
Randy Cox.  I shit you not.

   "I'll walk you out," Darcy said, taking my arm and leading me out of Mr.
Cox's office.

   My sister took me down a long hallway.  We passed a tiny room with a
copy machine in it and shelves full of paper.  She shoved me inside. 
Before I could protest, my pants were around my ankles and my dick was in
my sister's mouth.  I stared out at the halls, but while plenty of people
walked past, no one looked inside.

   "Holy fuck," I gasped as I shot rope after rope into my sister's mouth.
She stood up and wiped herself off with her sleeve.  "I don't think that
was a good idea," I said.

   "Really?" Darcy said.  "It felt like a good idea to me."

   *

   We fell into a routine.  Every morning Darcy would wake me up and we'd
go for a run.  After, we'd shower and dress, then I would make us both
smoothies and we'd go to work.  I'd go down to the mailroom and sort
packages, then deliver them.  I met all sorts of very strange, very rich
people who apparently stared at computer screens all day.  I honestly still
have no idea what those people did for a living, but they were all very
well compensated for it.

   Darcy and I would eat lunch together, then I would walk three blocks
west from the building and take the train back home.  When I got there, I'd
change into more comfortable clothes and make dinner, so it was waiting for
my parents when they arrived.  Darcy would come back much later and eat the
leftovers.

   Along with going to work every day, my sister would give me all sorts of
jobs.  Handjobs in the morning before our run (or after, or a few times
during), a blowjob in the men's room (or the copy room, or at Darcy's cube)
at work, then another at night after she came home.  Sometimes I would
finger or lick her in return, but it was usually 3:1 in my favor and Darcy
seemed fine with that distribution.

   By the end of the week I was exhausted.  As I passed out on my bed
Friday night, I realized I hadn't smoked up or even switched on my PS4 all
week.  Eventually, in my half-sleep haze, I felt my sister crawl into bed
next to me.  We didn't even bother with sex, just both slept there like the
dead.

   The next morning, a Saturday thank God, Darcy rolled over looking
positively bubbly.  Both of us were still in our work clothes from the day
before, but Darcy quickly stripped completely naked.

   "I don't want to run in the nude," I groaned.

   "We'll take a break day," Darcy said.  She started lifting my shirt off
me.  Through everything we'd done, completely naked sister remained a rare
sight.  But there she was in all her glory, golden-brown hair hanging down
over her chest.  Darcy saw me eyeing her and quirked her head at me.

   "Sorry," I said.  Some part of me still thought I shouldn't be perving
on my sister.

   "I like that you like me," Darcy said.  She climbed down and slurped up
my penis.  I settled back into enjoying my morning blowjob - one of Darcy's
slow-Saturday-specials - when my sister shifted.  She turned around,
putting her pussy right over my face.  Her scent overwhelmed me.

   "We can enjoy each other at the same time," Darcy said, mouth full of my
meat.

   Once again, I was surprised at another seemingly obvious variation on
our usual procedures.  I leaned my head up and started licking at my
sister, trying to match her pace.  We'd stroked each other off together
before, but this felt like a whole new level.  I tried my best to
concentrate on pleasing Darcy while she pleasured me, but it was hard. 
Darcy seemed to be having similar difficulties, but I realized that was
kind of the fun of it.

   Finally, Darcy's body tightened over mine.  Her legs and arms splayed
out and she shuddered.  Fortunately, having my dick in her mouth kept her
from making too much noise.  As the orgasm washed over her, Darcy grabbed
my cock and pumped me.  I responded immediately.

   My sister spun around with a goofy grin on her face.  We were both
covered in each other's cum.  She giggled and kissed me on the lips.  It
was a quick peck, but we both pulled back like we'd been shocked.

   There was a pause where we stared at each other.  That was new. 
Finally, Darcy relaxed and laid down, resting her head on my chest.  Idly,
she played with my cock, now lying on my thigh and quite soft.  In return,
I reached over and fondled her breast.

   "You like those, huh?" Darcy said.

   "They're kind of incredible," I said.

   "Boys," Darcy shook her head, "Trust me, the fun part is a bit lower."
She took my hand and put it on her pussy.  We both lay there and slowly
diddled each other.  Nothing came of it.  Eventually Darcy got up and left
my room.  I heard her turn on the shower.

   I got up and got dressed, happy to leave my formal clothes in the
dresser for at least a day.  My parents were already sitting at the table
eating breakfast.

   "Did Darcy sleep in your room last night?" Mom asked as I went into the
kitchen.  She offered me coffee, but I started to make a smoothie instead.
I couldn't believe my sister had me hooked on those awful things, but the
truth is I felt way better when I drank them instead of the usual crap I
put in my body.

   "Did she?" I asked, trying to seem confused.  Mom gave me her best
Mom-stare.  "Darcy came in early this morning, I remember," I said, "She
forgot it was a Saturday."

   My Mom continued to eye me as she sipped her coffee.

   "I think I'd remember if my sister was in my bed, Mom," I said.

   "Well, your father and I have errands to do," Mom said, "We'll be back
in about an hour." She stood up and kissed my forehead.  "You need a
shower," she told me, "You smell strange."

   I nodded, hoping she wouldn't press the issue.  A few minutes later, she
and Dad drove off.  Once they left, Darcy came downstairs.  She had on a
pair of jeans and a floral, sleeveless blouse.

   I handed her a smoothie and she took it, appreciatively.

   "Mom says I need a shower," I said.

   Darcy sniffed me.  "I like how you smell," she said, giving me a sultry
smile.

   My phone gleeped and I looked down.  There was a text from a bunch of my
friends.  They were all getting online to play Call of Duty.  I showed my
sister, but she shook her head.

   "I think we have enough entertainment right here, ourselves," she said.
"Besides, why do you need other people when you have me?"

   I didn't want to argue, so I texted and said I was busy.  I got some
mean looking emojis back, but I ignored them.

   When we were done eating, my sister decided that we should watch a
movie. I told her I doubted we'd be welcome back at the theater.  Darcy
laughed and went into the living room.

   She turned on the TV and found something mindless.  Then she sat down on
the couch and patted the spot next to her.  When I sat, Darcy climbed onto
my lap.  She pressed down, and I realized she was trying to recreate the
weekend before.

   My sister ran her butt up and down my rapidly growing shaft.  She made
little noises, but nothing else.  I stared at her back while she moved on
me.  It was kind of painful, kind of pleasurable, and I did my best to
focus on the good part.

   "Here," Darcy said.  She got off the couch and lay down on her back. 
Darcy directed me to lie down right on top of her so that my crotch covered
hers.  "Yes, like that.  Now push down.  Yes.  Yeah.  So good."

   Now I felt what Darcy had been enjoying.  Pressing into her like this
was nice, and I felt myself building towards something even nicer.  Darcy
felt it too.  Her face flushed.  We were so exposed, lying on the living
room floor on top of each other.  If my parents came back early, there
would be no denying what we were doing.

   That wasn't enough for Darcy, though.  She pushed me off and stripped
down to her panties.  She had on a pair of canary yellow underwear with a
bow at the top.  She motioned for me to do the same.  Now I was only in my
blue boxers.

   I lay back down on my sister and, wow, that was much better.  Darcy's
bare breasts pressed into my chest.  She wrapped her legs around my waist.
We moved back and forth on each other quite a bit like lovers.  Darcy was
breathing hard.  She ran her hands through my hair, over my back.  It felt
really good to grind on my sister.

   She paused again.  This time she pulled at my boxers.  I took the hint
and slipped them off.  Darcy took off her panties at the same time.  I gave
her a wary took.

   "Just.  On top," Darcy said.  Her breaths coming in gasps.  I lay back
down on my sister.  My cock nestled into her warm furrow.  We both groaned
as we made contact.

   We'd done so much.  This was something else entirely.  We humped against
each other on the living room floor.  My "uhn uhn uhns" mixing with Darcy's
"ah ah ahs." The heat of her slippery cunt on my rigid cock.

   Darcy squeezed my bare butt tight and I felt my sister cumming under me.
She squeaked.  Her back arched.  Then she shook.  On the Darcy Orgasm Scale
(or, as scientists refer to it, the DOS), she'd probably hit a 5 or a 6
there.  I rated the ones I'd given her orally as a 10, but honestly, I was
still calibrating the measurement.

   I kept grinding into my sister.  I hadn't gotten off yet, but I was
close.

   "OH!" Darcy cried out.  She arched her crotch upward and I felt my dick
slide back.  Suddenly, my very bare cockhead was resting right at my
sister's very bare pussy.  I could fall forward a centimeter and be
sheathed in her snatch.

   Darcy whispered in my ear.  "Put it in."

   What?

   I stopped in place.

   "Put it in me.  Please," Darcy said.  She looked at me with wide,
wanting eyes.

   The reality of what we were doing - who I was with - rushed over me like
ice water.  I was humping my sister.  My sibling wanted me to have sex.  My
dick shriveled down to nothing.  I rolled off to the side.

   Darcy seemed to immediately see the change in me.  She hugged me close.

   "We can't do that," I said, "That's sex.  You said we can't have sex."

   "It's alright," Darcy said, "I want it real bad and I know you do, too."

   "Are you even?  I mean, do you take the pill?  Or whatever?"

   Darcy bit her lip.  "I trust you," she said quietly.

   "We can't do that," I said, "You said it was wrong, Darcy.  It's wrong.
We shouldn't.  Fuck, we're not supposed to be doing any of this."

   My sister lay back shellshocked.  I grabbed my clothes and put them on.
I felt icky, literally gross.  I went upstairs and got in the shower.  All
the things we'd done came racing back to me.  I couldn't get them to go
away.

   When I got out of the bathroom, Darcy was waiting for me.  She was fully
dressed.  "Ethan, I'm sorry," she said.  "I got carried away in the moment.
You weren't ready for..."

   "Ready?  How could I ever be ready for that?"

   Darcy winced.  I'd clearly hurt her feelings.  She took a deep breath. I
saw her face go stony.  "You sure seemed ready for all that other stuff,"
Darcy said.  "You're supposed to be different.  But you're like every other
boy.  You only care if you get yours."

   "Darcy, I..." My sister's sudden change of tone surprised me.  I hadn't
expected her to fire back, and now I found myself unprepared.  "That's not
true," I said.  "I love making you...  Well.  You know.  It's amazing."

   "But it's wrong," Darcy said.

   "No!  Well, yes.  I don't know.  Fuck," I said.

   Darcy took a deep breath.  "OK, I know you're new to all this stuff and
it can be scary," she said, "But that's why we're doing it.  So you can be
ready for a real girlfriend.  Like Victoria from the lingerie store.  She's
going to expect you to take care of her and I'm showing you how.  I'll take
the lumps for now, but I expect you to learn."

   I nodded.  "I'm sorry, Darcy."

   "Me too," my sister said.  She kissed me on the forehead, then stepped
away.  We searched each other's eyes for a moment.

   I heard the front door open as my parents came home. At least we're
both dressed, I thought.  Darcy walked past me and into her bedroom,
shutting the door behind her.

   That night, after dinner, Darcy came into my room like always.  We acted
like it was all the same, but it wasn't.  She gave me what I can only
describe as a cursory handjob, then stood up stiffly.  I offered to return
the favor, but she waved me off.

   "I have to get up early for work," Darcy said, "So I probably won't have
time to help you tomorrow morning."

   "Tomorrow's Sunday," I said.

   "I know.  It's some emergency thing," Darcy said, "I'll be back as soon
as I can."

   I felt a strange sadness well up in my chest as my sister switched off
the light and left my bedroom.

   *

   The next morning, I woke up to my cell phone screaming at me.  I picked
it up and saw that my sister was calling.

   "Ethan, thank God," Darcy said when I picked up.  "I have a serious
problem."

   "What's wrong?" I asked, groggy.  My first thought was that she'd been
in an accident and it made me almost nauseous with worry.

   "My work computer crashed, and it wiped half my hard drive.  The techs
say they can get it back, but I've got a meeting in five and I can't wait
that long.  I need the Anselmo Case file.  It's in my backup storage on the
laptop in my bedroom."

   I popped out of bed and raced over to Darcy's room.  I opened the door,
phone in my hand, and went straight to her desk.

   "There should be a thumb drive in the laptop, you see it?"

   "You want me to bring it over to you?" I asked, "I could probably borrow
Mom's car."

   "Not enough time," Darcy said, "Just turn on the laptop." She gave me
her passcode and had me go into her e-mail and send her the file.

   "Thanks, bro.  You're a lifesaver," Darcy said when the message came
through, then hung up.  I sat back in her chair, exhausted.  I'd just
gotten up and I already felt like going back to bed.  If that was Darcy's
job on a Sunday, I was happy to be in the mailroom.

   I looked at her computer screen, dumbly.  It had the standard green
field and blue sky that came with Windows.  The desktop was almost
completely clear.  A few programs, the usual icons, and one folder dragged
to the middle.  It was labeled 'E.'

   I told myself to shut down the computer, but my curiosity got the better
of me.  After all, the folder had my name on it.  Right?

   I opened the file.  My eyes went wide.

   *

   I waited until Darcy came home.  It was another super late night for
her, and she didn't show up till well after my parents had gone to bed.  I
saw her headlights scan down our sleepy street.  Heard the door as she came
inside.  I stayed still, in the dark, sitting right at my sister's laptop.

   Darcy came upstairs.  I heard her check my bedroom, then she opened her
own door.  She saw me sitting in her chair and jumped.

   "Sorry, E, I didn't expect you in here," she said.

   I didn't reply.  I took the laptop off the desk and showed it to her. 
My sister looked confused, then certainty filled her face.  Anger and a bit
of fear.

   "You went through my private stuff," she said.

   "It was an accident," I lied, "When you asked me to go into your email,
I opened it by mistake."

   My sister stayed standing, staring at the laptop screen.  I knew what
she was looking at.  I'd spent all day going through it myself.

   The 'E' folder was porn.  Lots and lots and lots of porn, enough to
dwarf even my own comprehensive collection.  Unlike mine, though - which
had a variety of different fetishes and themes to fit my many different
horny teenaged moods - my sister's smut was centered around one specific
thing: incest.  Brother/sister incest.
She had videos of supposed siblings, movies, captioned pictures, audio
recordings, short stories, full novels - all of it.  Any kind of porn you
could imagine, she had it, and it all featured siblings doing the one thing
they're not supposed to do together.  The very thing I'd been doing with

Darcy.

   "How long?" I asked.

   "What?" Darcy asked absently.

   "How long have you had a thing for me?"

   "I don't have 'a thing' for you, Ethan," Darcy said, hotly.

   "This whole time you've been acting like it was a mistake, or luck, or
you taking care of me," I said, "But that's not it at all, is it?  This has
been about you fulfilling your weird fantasies."

   Darcy didn't say anything.  She was wearing a pink and white whorled
sleeveless dress.  Professional for her big meeting that morning, I
supposed.  The laptop was the only light in the room.

   "So, you've, like, always had a crush on me," I said.

   "No, Ethan," Darcy said, "This isn't about you.  I mean, not really."

   I gave her a dubious look.

   "I mean, you're cute.  Kind of.  Especially since you've started working
out and dressing up.  But if you were just another boy, there's no way I'd
be attracted to you."

   I had to admit, of all the reactions I expected, Darcy's personal attack
wasn't one of them.  I told myself it didn't hurt, but it did.

   My sister sat down on her bed and motioned for me to join her.  "Look,
I'm sorry that you found all this.  That it gave you the wrong idea.  God,
this is hard to explain.  I don't get turned on by you."

   I made that wounded puppy dog face again.

   "Look, the thing that gets me going?" Darcy said, "Is that you're my
brother.  That's what makes it hot for me.  That's what turns me on."

   "Incest," I said.

   "Brothers and sisters," Darcy said.  "Nothing else."

   I almost laughed, how she said it so casually.  Like what she was into
was totally normal and everyone else was the weirdo.

   "I don't get it," I said.

   "I don't either?" Darcy said.  "I can't help how I'm wired.  When I
found these things, I realized they turned me on.  Like, really.  And the
more I found of it, the more I liked it.  Look, Ethan, don't be hurt.  I
guess you're handsome in your own way.  I mean, that girl at the lingerie
store was really into you, I could tell.  But for me? 
It's because you're my brother that makes it hot."

   "So, if I was a dude on the street and some other guy was your brother,
you'd be into him?"

   Darcy shrugged.  "Probably."

   "Darcy, that's weird," I said.  Again, I was speaking before my brain
could vet the words.

   "I know," Darcy said, "But it's me." She stood up, took her laptop out
of my hands, and carefully put it back on her desk.  "You have to admit
you've been having fun."

   "It was," I said, "It is." I couldn't believe I was saying this.  Was I
actually trying to keep my semi-sexual relationship with my sister?"

   "See, you kind of get it," Darcy said, "You're acting all ashamed, but
the truth is you like it, too."

   I nodded.  I couldn't lie to my sister.  Maybe a week before I'd have
felt differently.  But in that moment, I wasn't going to let it go.  At
least, not completely.

   "So, you still want me to wake you up in the morning," Darcy said.  She
gave me a coy smile.

   "I want to wake you up, too," I said, accenting the word 'wake.' "But we
can't have sex."

   Darcy's face went from grin to grimace in a second.

   "That's a different line, Darcy," I said, "I don't think we should cross
it.  Even if we want to, it's too strange.  And dangerous."

   "Lots of other siblings do it," Darcy said.

   "Fool around?" I asked.  "Yes, I bet they do.  It's probably natural
when you're young and horny and there's a girl or a boy right there.  But
actual, total, full-on sex?  There's no way.  I mean, it's illegal."

   "Yes, they do," Darcy said.  She was pouting now.  "Brothers and sisters
have sex.  All the time.  And I can prove it to you."

   "I'm pretty sure those videos are fake," I said, "And those stories are
written by creepy, loveless virgins and old pervs."

   "I can prove it," Darcy said, "With real people that we both know."

   "OK, seriously?"

   "Sam and Dave," Darcy said, she sat back, arms crossed, like she'd won
the argument.

   "You mean the gay couple down the street that just adopted that really
cute Asian baby?"

   "No!  Samantha, my friend from high school.  You remember Sam?"

   I did remember her.  She was blonde and cute, though way less curvy than
my sister.  She had a real 'girl next door' look to her and I'd had a bit
of a crush.  Of course, I was 16 at the time, I had a thing for every one
of my sister's high school friends.

   "Right, so her and her brother David," Darcy said.

   "They fool around," I said.

   "They have sex," Darcy said, "All the time.  They could be doing it
right now for all I know."

   I raised an eyebrow, but I didn't say anything.  The 'prove it' was
implied.

   "Fine," Darcy said, crossing her arms under her breasts.  "I'll show
you."

   "Uh huh," I said.

   "I will," Darcy said, "I just need a little time to figure out how."

   "OK," I said.  I pictured her at a casting agency trying to hire actors.
Or forging a signed affidavit.  There was no way my sister was going to
convince me that Sam had sex with her brother.

   "And to show you, no fun stuff till I do," Darcy said.  Then she threw
me out of her bedroom.

   *

   The next morning, I woke up with the king of all hard-ons.  I lay back,
waiting for my morning appointment, but my sister never showed.  Worse, I
tried to stroke it myself and found that it wasn't even all that
satisfying. I gave up before I climaxed.  It wasn't worth it.

   I saw a text from Darcy telling me that she had to head out early and I
was on my own for getting to work.  I rolled out of bed and went for my
morning run, then showered and got dressed for work.  I took the train into
the city, not a bad ride, and was in the office with time to spare.

   I went over to Darcy's cube, but my sister wasn't there.  I had lunch by
myself, as well.  Then I went home and cooked dinner for the family.  That
night, again, I stayed in bed and waited for my sister to show up.  But
when she did, she went straight to her room without even saying goodnight.

   "Are you two fighting?" my Dad asked over breakfast the next day.

   "I don't know," I said, honestly.

   Three days went past like that, to the point where I started to wonder
if my dalliances with Darcy had all been imagined.  What made more sense,
that my sister had started doing dirty stuff with me and stopped, or that
it never happened in the first place?

   Then, in the middle of the workday on Wednesday, my sister came and
found me in the mailroom.  I worked with two other guys, both in their
fifties, who liked to listen to Howard Stern extra loud and talk about
girls they'd nailed at truck stops.  They nearly lost it when Darcy showed
up in the doorway.

   "That's my sister, guys," I said.

   "That's sex on legs, dude," one guy responded, even though my sister was
standing right there.  She gave him a tight smile.

   "We need to talk," Darcy said to me.  I nodded.  I braced myself for the
breakup speech.  How had I ended up in this place where I was actively,
actually worrying that my sister was going to stop forcing me to have sex
with her?  "Something's come up at home that we need to deal with.  I
already spoke to my boss and yours.  We need to leave right now."

   I looked over at the other two guys.  They shrugged and went back to
filing.  As soon as I was out in the hallway, I accosted my sister. 
"What's wrong?  Are Mom and Dad, okay?"

   "Pfft, they're fine," Darcy said.  She started walking down the hallway
to the elevators.  "I needed an excuse to get us out of here early. 
'Personal emergency' was both appropriate and accurate."

   "So, there's nothing actually wrong," I said, following my sister a few
steps behind.

   "I need to get laid," Darcy said, "That sounds like a personal emergency
to me."

   We went down to the garage and got in Darcy's car.

   "You want to drive?" Darcy asked.

   I was about to kneejerk a no, but I saw the look in her face and
recognized the peace offering she was giving me.

   "Sure," I said.  I was able to get us out of the garage without incident
and only stalled once on the way to the highway.

   "You're getting way better at this," Darcy said.

   "Thanks," I said, accelerating past a slow-moving truck.

   "You're getting way better at a lot of things," Darcy said.  I looked at
her body and gave her a saucy smile.  "Not that.  Well, OK, that too.  No,
I meant, like, the life stuff.  You've run every morning this week, haven't
you?"

   I told my sister that I had.

   "You're eating better.  Your cooking is almost edible.  You stopped
smoking pot.  You're turning into quite a catch, little brother.  Good
thing I've already got you in my net," Darcy said, "Although if you want to
call that Victoria girl from the lingerie store, I'm willing to let you. 
With certain caveats, of course."

   I decided that this was Darcy's weird way of trying to give me a
compliment, so I thanked her for it.

   "You're welcome," Darcy said, "You're the one who's doing all the work.
I had to give you a little nudge, that's all.  I know the last few days
have been hard for you, but I promise the payoff will be worth it."

   I looked at my sister and paused.  To this point, I'd assumed we were on
some mid-afternoon nookie run.  Suddenly it occurred to me that she might
have something more planned.  After all, since when did Darcy need to leave
the office to suck me off?

   "We can't have sex, Darcy," I said.

   "You're going to love this," she said, "You'll see."

   I felt my stomach churn a little.  Amazing how much a car, a vehicle
speeding down the road at 70mph, could feel so much like a cell.

   "And after?" Darcy said, "I've been thinking.  My office and your school
aren't far from each other at all.  If we live together, we could probably
spring for an apartment, you and me.  Wouldn't that be awesome?"

   I pulled off the highway and turned down the road to our house.

   "Turn left up at the light," Darcy said.

   "That's not the way home," I said.

   "We're not going home," Darcy said.  I tried to think of all the random
places my sister might try to give me a blowjob.  A convenience store, a
bar, a playground, a library...  They all seemed so implausible.  Which
only made them all likely Darcy sex sites.

   My sister had me turn us onto a suburban road and I realized I
recognized where we were.  This was the other side of town, one of the more
upscale neighborhoods.  When had I been here before?

   "Sam's place is right up on the corner," Darcy said, "So you should
probably park here.  Don't want to be too obvious."

   Sam.  Samantha.  As in Samantha and her brother Dave.  The ones my
sister swore were secret sibling sex buddies.

   "We're going to Sam's house?" I asked.  The knots in my stomach twisted
around each other.  I was running out of intestines to bend.

   "Duh.  This took a lot of doing, so don't screw it up," Darcy said.  She
took my hand and led me down the street.

   Sam's house was one of those McMansion places that were built in the
early aughts before the economy went down the tubes.  The whole
neighborhood was one big house next to the other till the scale got messed
up and you thought it all looked normal.  Like seeing a parking lot full of
Hummers, a relic from another era, yet no less impressive.

   My sister led me across Sam's well-manicured front lawn and around to
the back of her house.  There was an inground pool and a small patio with a
barbecue set that cost as much as a new car.

   Darcy pulled at the sliding glass door and it opened easily.  She put
her finger to her mouth.

   "Do they know we're coming?" I asked, staying outside.

   "Sam does," Darcy said, "Dave doesn't.  Come on, we have to hurry, or
all my work will be wasted."

   The house seemed empty.  Our footsteps echoed.  We walked through the
massive kitchen and up the stairs.  On the walls were multiple pictures of
a happy family through the years.  I recognized Sam in them and realized
that her whole family had the same exact nose and mouth.  They looked less
like relatives and more like strange clones of each other.  It was
unnerving.

   Down the hallway, Darcy led me back to a boy's bedroom.  It was painted
grey with walnut furniture.  A couple of sports trophies sat on one of the
dressers.  There was a closet on the back wall with slatted, white, wooden
double doors.

   Darcy threw open the closet and pushed me inside.  She followed after
me. We were covered in heavy coats, standing on old shoe boxes, but there
was enough room for both of us.  More importantly, we could both see out of
the slats and into the boy's bedroom.

   I started to ask a question, but Darcy shushed me.  We stood there,
silent, staring at the empty room.  The closet started to feel hot.  It
smelled of mothballs and old leather.  I felt like a criminal.

   I heard the sounds of heavy footsteps.  Then voices.  I recognized Sam's
immediately.

   "No, your room," Sam said.

   The door popped open and two twenty-somethings fell into the room,
wrapped around each other.  They were kissing like it was the only way to
get oxygen.  The room filled with the sounds of gasping mixed with wet
smacks.

   Sam was even prettier than I remembered.  Her body had filled out some,
but she was still straight as a board compared to Darcy.  There was no
doubt that the boy she was kissing was her brother.  He had that same
family face.  Their hair was even the exact same color.

   There wasn't a lot of foreplay or dirty talk.  The siblings were
comfortable with each other in a way that felt very natural between them.
Though there was nothing rote about their passion.  They kissed with the
familiarity of lovers, but they acted with the starving urgency of the
ravenous.

   "OK, you've made your point," I whispered to Darcy.

   She grabbed my wrist so tight it hurt.  "No, not yet," Darcy said, "Just
watch."

   Sam pulled her brother's shirt over his head and kept kissing him.  Dave
was well built, with broad shoulders, defined pecs, and only the very
beginnings of a gut.  He had a small amount of light blond chest hair that
formed a "T" over his chest and stomach.

   Dave reached over and pulled off Sam's t-shirt.  She wasn't wearing a
bra, and her breasts popped free.  They were as small as I'd imagined,
topped with light brown nipples that were screwed so tight they looked
ready to pop off.  I have to admit, there was something sexy about Sam's
tiny titties and washboard stomach.

   Dave trailed kisses down his sister's neck, taking her needy breast into
his mouth.  Sam gasped like he'd hit a live wire.  I didn't remember Darcy
ever being that excited about nipple play.

   My sister shrugged.  "Everybody's wired differently," she whispered.

   While her brother suckled at her teat, Sam reached down and started to
undo his pants.  For a moment, I saw Sam's eyes drift over to the closet.
The cute blonde gave us a little wink.  I don't know if knowing Sam knew we
were there was a turn on or if it made this whole thing worse.  Kind of
both, honestly.

   Sam pulled off Dave's pants and underwear in one go, leaving her younger
brother completely bare.  They were still kissing, but now Sam was pushing
Dave back onto the bed.  She had her hand wrapped around his hardness and
was slowly stroking him up and down.  I noticed Dave had a perfectly
serviceable dick, maybe a bit longer than mine but a good amount less in
girth.  Neither of us had anything to be ashamed of, certainly.

   Dave shucked off his sister's pants and now they were both completely
naked.  Their tongues danced in each other's mouths while their hands
plumbed at each other's sex.  Sam had a cute little bottom, pinkish.  In
her position I couldn't see her pussy, but I glimpsed a small patch of
curly blonde hair.

   I didn't need to see Sam's snatch to realize what was happening next,
though.  The blonde girl shifted her bottom and her brother's dick slipped
into her body like a magic trick.  Poof!

   Sam and Dave both groaned simultaneously as they made that most intimate
connection.  Darcy elbowed me in the ribs, pointing at the siblings.  As if
I didn't already see what they were doing.

   They settled into an easy rhythm, Sam riding her brother.  He leaned up
and kissed her breasts.  She reached down and strummed her clit.  Both of
them made lewd noises - their bodies squelching and sighing.

   "Fuck, brother, you feel so good," Sam said, "I love that big dick
inside me.  You going to do it?  You going to give your sister your load?
Make her cum on your cock?"

   She stiffened, and I recognized the telltale signs of a woman having an
orgasm.  Sam's body stumbled and her head fell back.  Like she lost control
of herself entirely for a moment.  Then she popped back up again and kept
humping at her brother.

   Dave cackled.  He grabbed Sam by the sides and flipped them both over.
Now he was between her legs, pounding her pussy mercilessly.  Reducing his
sister's words to nothing but cries and squeals.  The both of them seemed
to regress to an almost animal state, rutting on the bed.  Darcy and I
could have thrown open the closet doors and I doubted either would have
even paused.

   I'd watched plenty of people having sex on the Internet.  This was
different.  There was something raw about being right there.  Not just
seeing them together but smelling them.  Practically tasting it.  It wasn't
polished and perfect like the sex I'd seen online.  Dave's cock slipped out
a couple times.  Sam stopped him once because the angle was hurting her. 
All of that reality made it more arousing, not less.

   I could tell that both siblings were racing towards a climax.

   "I.  Love.  My.  Sister!" Dave said.  Chanted.  Again and again with
each thrust.  The bed slammed against the wall.  Sam slammed into the
mattress.

   "Dave I'm getting close.  Need you to...  Want you to..."

   Dave grunted.  His body went stiff.

   "Oh YES!" Sam cried.  Her brother buried himself in her body and went
stiff.  Sam, on the other hand, seem to come alive.  Arms and legs
flailing.

   Brother and sister flushed, then fell into each other's arms.

   "Oh God, baby, that was so good," Sam said with a sigh.

   Dave buried his head in his sister's shoulder, laughing.  "Man, what got
into you today?"

   "I missed my baby brother," Sam said.  But she was staring at the closet
when she said it.

   The two siblings lay languid together in bed.  Lazing around in post-sex
happiness and genuine affection.

   Gradually, Sam got up and got dressed.  She did it slowly, like she was
enjoying her audience.  She took her brother's hand and pulled him up from
the bed.

   "Want to nap," he said.

   "Mom and Dad will be home soon," Sam said, "They can't know we skipped
out of work for sex."

   Dave got up reluctantly and pulled on his clothes.  Then the siblings
left the room.  A moment later, we heard the front door slam behind them
and two cars drove off.

   Once we were sure the coast was clear, Darcy opened the closet door. 
The bedroom stank of pussy, cock, and cum.  My sister cracked one of the
windows before we walked out of the bedroom.  I guess it was a courtesy.

   "See?" Darcy said as we walked down the stairs.

   "Yes, you were right," I said, "They're having sex."

   "Have you ever had sex before?" Darcy asked, though she knew that I had
not.  Seemed kind of cruel of her to ask, to be honest.  "Well, I have. 
And let me tell you.  Sex is great, but it's never like that."

   "Maybe he's just, like, really good at it," I said.

   "No," my sister said wistfully, "He's not."

   "You and..."

   "My, um, thing?" Darcy said, "My fetish?"

   "The incest thing," I said.

   "Yes, well I lied before about how I got into it.  I can tell you the
exact moment I started seeing brothers and sisters differently.  We were
having a sleepover at our house and Sam told me she and her brother were
having sex.  Something about it...  I don't know it triggered something in
me.  That's when I started reading incest stories, watching videos, all of
it."

   "I guess that makes sense," I said.  Our voices echoed in the empty
kitchen.

   "Well, I told Sam how much it turned me on.  She let me watch her with
Dave sometimes.  Like we did today.  Then one day I couldn't help it?  It
looked so good and...  It wasn't the same.  It was kind of lousy,
actually."

   "So, Dave isn't the world's greatest lover?"

   "Not even close," Darcy said.  "What makes the sex so amazing for her,
for them?  It's this." Darcy tapped her hand on my chest and then hers. 
"That's what's different.  That's what makes it special."

   Darcy slid open the back door and froze.  I stepped out and saw it, too.
Sam's parents were literally pulling up the driveway while we exited their
house.

   "Fuck," Darcy said.  We crept back to the far side of the yard.  Hid
behind the barbecue equipment.

   "I think I saw someone in the back," we heard Sam's Dad say.

   "Fuck!" Darcy said it again.  We both looked around, frantically.  For a
moment, I thought about jumping in the pool, but I doubted I could hold my
breath long enough for Sam's parents to go away.  My eyes alighted on the
back fence.  It wasn't too high to scale.

   I grabbed Darcy's arm and we raced to safety.  I gave my sister a boost,
then I scrambled up the wood myself and toppled over.  I heard Sam's father
yelling after us.

   I sprawled onto the hard ground in a stranger's backyard.  Their house
was the mirror image of Sam's, but no pool.  Darcy grabbed my arm and
pulled me up.  We both sprinted out of the backyard and out onto the
street.

   "He's going to come around this side to look for us for sure," Darcy
said.

   We quickly made a run for it, traipsing through the neighborhood at
random.  I was even more thankful now that my sister had been getting me in
better shape.  I was almost able to keep up with her as we careened around,
trying to escape.  Finally, we got to the far side of the community.

   Darcy bent over, panting, resting her arms on her knees.  I mirrored
her. We shared a wild look.  No one seemed to be coming after us.

   "Well, that was an adventure," I gasped.

   My sister reached over, grabbed my cheeks, and kissed me on the lips. 
So hard our teeth knocked against each other.  We were dripping with sweat,
covered in grass from our fall.  I didn't care.  My breath caught in my
throat and I kissed my sister.  Holding her body tight to mine.

   *

   We waited a little while, then snuck back to Darcy's car.  She let me
drive us home and I didn't stall the whole way.

   "I think you're getting this, bro," Darcy said as we turned into our
driveway.

   Our parents were already home, so we ordered pizza ("Long day at work,"
Darcy explained when they asked why I wasn't home to make dinner).  We all
ate together, and it was nice, the four of us.  Darcy wasn't that different
from our family.  She had my Dad's sense of humor and shared my Mom's love
of music.  She stood out, of course, but that's only because she was
amazing.  For the first time in a long time, I felt comfortable in my own
skin, my own life.

   But Darcy didn't come to my room that night.  "I know it's tough, but
wait till the weekend," Darcy said.  "Promise me you won't do anything in
the meantime." She went to her own room to sleep.

   We went for a run the next morning and carpooled into work.  This was
nice, living our lives together.  I wondered if we could do it without the
sex.  My dick, in a constantly half-hard horny state, did not like the idea
of that one bit.

   That night, while we were doing the dishes, Darcy told me she'd gotten a
text from Sam asking if we'd enjoyed the show.

   "I still can't believe she let us watch them," I said.

   "That's her fetish," Darcy said, "Being seen."

   With all the blowjobs my sister had given me at work, at the mall, and
all over the neighborhood, I didn't think that turn-on was unique to Sam,
either.  But I didn't say anything.

   *

   I was on my way home on Friday afternoon when I got a text from my
sister.
Darcy: Don't make dinner tonight.

   I sent back a confused-face emoji.
Darcy: Trust me.

   She sent me emojis of an eggplant and a taco.
Me: We're getting eggplant tacos?!?!
Darcy: You're an idiot.
I was twenty minutes into my train ride home before I realized what she

meant.

   When I got to the house, I started to get out of my work clothes, but
something stopped me.  My old uniform of a t-shirt and boxers felt odd. 
Like they were someone else's clothes.  I resolved to ask Darcy to take me
shopping that weekend.  My job at her office paid me next to nothing, but I
had enough to splurge a little.

   Instead I went downstairs and did some chores.  I emptied the fridge and
cleaned it out, washed the bathroom, and vacuumed the carpet in the family
room.  The house wasn't sparkling clean or anything, but I had to admit it
felt way better that way.  When I was done, I felt dirty, so I went
upstairs and showered in the newly scrubbed tub.

   After I got out, I took out a clean, scarlet dress shirt and charcoal
pants and changed into those.  When I opened the drawer, I noticed my
little bag of weed looking up at me, lonely.  I smiled ruefully - it hadn't
even occurred to me to smoke up the whole week.  In fact, the idea didn't
appeal at all.  I wondered if I knew anyone I could sell the rest of it to.

   While I was getting dressed, I heard my parents' pull up in their cars.
First my Mom and then my Dad.  I went out to greet them, but they both went
straight to their bedroom.  I heard a shower running from the Master.  I
wondered what they were up to, but I went downstairs so they could have
some privacy.

   My Dad came down first, dressed in corduroy pants and a grey sport coat.
My Mom was right behind him wearing a long emerald dress.  It was weird
seeing my tomboy Mom dressed in anything but a t-shirt and jeans.  They
were both dragging small suitcases behind them.

   "Darcy got us reservations up at Mt.  Airy for the weekend," Dad said.
He rubbed his hands, very pleased.  "Plus, dinner reservations for tonight.
Your old folks are going to be living it up."

   "Wow, that's very generous," I said.

   "She said it was to thank us for letting her stay at the house while she
gets her career started," Mom said.

   "Honestly, the both of you have been such model children lately," Dad
said, "It makes me feel proud as a parent."

   "Make sure you thank your sister for us when she gets home," Mom said.

   "Oh, I will," I said, "As often as possible."

   My parents went outside, got in Dad's car, and drove off.  I stared,
stunned, at the door.

   A few minutes later, Darcy's car took my Dad's spot in the driveway. 
She bounded up the front steps.  I opened the door and let her in.

   "Did they leave yet?" Darcy asked.

   "They're long gone," I said.

   My older sister came into the house and tossed her bag on the couch. 
She leaned in and gave me a kiss on the cheek.

   "Don't you look nice," she said.

   "Darcy, hang on," I said.

   My sister gave me a wary look, but she stayed next to me.  Rested her
hand on my shoulder.

   "I know you did all this for us, and I appreciate it.  And after seeing
Sam and her brother this week, well, it definitely changed my outlook on
some things," I said.

   Darcy nodded.  "I'm glad," she said.

   "And while I want to move things forward with us, I'm not sure I'm
ready. For that.  I mean, I'm not saying I won't be, but right now it
still seems like a big change in our relationship and I don't want to jump
into it.

   "Darcy you're beautiful and sexy and amazing.  And I'm not saying we
shouldn't do, you know, stuff.  Not only for me, but for both of us.  But
the other thing, that's a big step.  I'm not saying never, I just want you
to know that it's probably not going to happen tonight.  Or tomorrow. 
Maybe not for a while.  If that's OK?"

   Darcy smiled at me and rubbed my head the way she always did when she
thought I was being silly.  "It's fine, E."

   "I mean, if you want to call Mom and Dad back or..."

   "The two things are unrelated.  I've been planning to do that for them
for a while.  And you can take all the time you need," Darcy said, "Our
alone time is special to me, to us.  We can do whatever you like.  I'm sure
you're backed up from nearly a week of no release.  I'm going to need, you
know, some stuff, too.  But that can be however, whenever we want.  There's
no pressure."

   My sister walked into the kitchen, leaving me behind, dumbfounded. 
There was always pressure.  Wasn't there?

   "I'm hungry," Darcy said.

   "You told me not to make dinner," I said.

   "We'll order Chinese," my sister said.

   We had a small feast in the kitchen, after which Darcy went upstairs to
get out of her work clothes.  I went into the kitchen and washed the
dishes.

   When I was done, I heard my sister calling me from upstairs.  I went up,
but both our bedrooms were oddly empty.

   "Down here," Darcy said.  I looked and saw a flicker of bare sister
flesh through the opening to my parents' master bedroom.  Oh boy.

   I slowly walked down the hallway.  The door to the bedroom was open. 
Darcy was lying on my parents' bed, awash in the bluish glow of their TV.
She was wearing the cherry red teddy from our day at the mall.  And nothing
else.

   My sister's hair was up.  Her fingernails painted the same red as her
lingerie.  Shining diamond studs in her ears.  She'd put on a little
makeup, pinking her cheeks and darkening her eyes.  Darcy smiled at me and
patted the other side of my parents' bed.

   "Keep me company," she said.

   I took off my shoes and climbed next to my sister.  My heart pounded in
my chest.  My dick stretched out, hard, like it was trying to reach for my
shins.  My balls were already aching.

   Darcy leaned over and kissed my cheek.  She dragged her hand down my jaw
line, keeping eye contact.  She didn't say anything.

   The TV was showing some reality thing.  For a moment, I thought my
sister had put on porn, but that's just the state of television these days.
Even the chaste stuff looks dirty at a glance.

   It didn't matter what was on, I couldn't stop glancing over at my sister
in her bright red lingerie.  Darcy noticed, too, and gave me a very warm
smile.

   "You lasted all week," she said, proudly.  "I don't know how you
managed. I barely made it, myself."

   "I wanted to wait for you," I said, "You're worth it."

   "Ethan, I know I said before that it wasn't about you," Darcy said, "But
I'm glad it is you.  I hope you know that."

   I nodded.  Still staring at my sister's chest.  Watching her breasts
rise and fall.

   "You sure you didn't like Sam's little tits better?" Darcy asked,
following my eyes.

   "You must be joking," I said.

   Darcy rolled over and kissed me on the forehead.  On the cheek.  Then
finally on the lips.  The third time was no less weird than the first, but
like a lot of things, I was getting used to it.  My older sister pressed
her lips to mine.  She slipped her tongue into my mouth.  We held each
other tight and I felt something overwhelm my fear, my instinctual disgust,
my raging desire.  Love.

   I loved my big sister.  I knew it in my heart.  But when I tried to
break our kiss to tell her, Darcy pushed me down with her mouth and made
sure I couldn't stop kissing her.  And then I very much didn't want to
stop, either.

   Darcy was the one who broke it.  She kissed down my neck and,
tantalizingly, started undoing the buttons of my dress shirt.  She pulled
it off me and kissed my chest.  I tried to return the favor, but Darcy
shook her head at me.

   She trailed wetly down my stomach, then undid my belt and pulled my
pants down.  I was naked in my parents' bed, my cock sticking up so
straight you could put a bulb at the top and prevent ships from crashing
into shore.  My sister, in sexy underwear, perched over me.

   "You sure you didn't like Dave's little prick better?" I asked as my
sister eyed my dick.

   "Oh, fuck no," Darcy said.  She wrapped her lips around my cock and
lightly sucked at it, just enough for a taste.  Then she sat up on her
haunches.

   My sister slipped off the shoulders of her bright red teddy, strap by
strap.  Her gorgeous breasts popped into view, her dark red nipples sharp
as I'd ever seen them.  This time, I wouldn't let my sister push me back. I
leapt forward and kissed her, hard, grasping her breasts and squeezing them
for all I was worth.

   They felt so good in my hands, so full.  The tips of her nipples
scratched at my palms.  Her ample tit flesh overflowed my grip.  I hefted
one up and put the nipple to my mouth.  I kissed, then nibbled, and my
sister squirmed.  OK, so maybe nipple play was a turn-on for her after all.

   I spent as much time as Darcy would let me making love to her perfect
breasts.  She hummed and held my head tight as I sucked, like cradling me,
safe.  I slipped my hand down her bare side and found the last of her
lingerie pooled at her wide hips.

   I pushed it down and Darcy lifted up to let me.  The underwear I'd
longed to see her in got tossed to the floor like it was worthless.  Next
to my naked sister, nothing was worth keeping.

   Finally, the big moment.  Not her ample breasts or her wanting pussy.  I
reached behind my sister's head and pulled out the tie.  Her light brown
locks came down in perfect rivulets over her shoulders and chest.

   I sat back and stared at my exposed sister.  Taking her in.  Her
breathing was shallow.  Her eyes flitted back and forth.  Was Darcy
nervous? I don't think I'd ever seen my older sister anxious before.  Not
like this, anyway.

   "You're amazing," I told her.  "I'm so lucky to have you as my big
sister."

   "Damn straight," Darcy said.  Now there was the older sibling I knew and
loved.

   I took my sister in my arms and we held each other tight, the warmth of
our naked bodies pulsing against each other.  I caught the hint of my
sister's arousal and it called to me.  I pushed her back on our parents'
bed and kissed my way up her legs.  Her thighs were already sticky with her
juices.

   "Ethan," Darcy put her hands on my head, but I pushed forward despite
her protestations.

   "You first," I told her.

   Darcy didn't say anything, so I took it to mean she accepted my
argument. I lapped at my sister's slit and she moaned.  She tasted slightly
different somehow.  Just as good, but a little stronger maybe?  I noticed
her lubrication wasn't as I remembered either - it was clearer than I
remembered and slightly thicker.

   Darcy ran her hands through my hair and kept suckling at her sex.  I
tongued deep inside her cunt and felt her body tighten to my delight.  Then
I found her clit with my finger and my sister shook like she'd been
shocked.

   "Oh wow," Darcy said.  She sat up and this time pushed at my head more
forcefully.

   "Did I do something wrong?" I asked.

   Darcy kissed me, tasting herself on my lips.  "No, you're perfect," she
said, "I just want to make you feel good, too.

   Darcy pushed me back by the shoulders.  She climbed on top of me.  I
waited for her to spin around so we could get each other off, orally. 
Instead, my sister kissed my lips again.  I felt her shift her hips, so
that my cock was pressed against her sex.

   "Darcy," I said.

   "It's OK," Darcy said.  "Just...  just rubbing."

   She made her point by grinding down on my cock.  We both groaned in
pleasure.  I arched my butt upwards to increase the contact.  Darcy's eyes
rolled back as another small orgasm coursed through her.

   My sister put her hands on either side of my arms and rolled her pussy
back and forth over my cock.  It felt amazing, the heat and lubrication of
her sex dripped down my dick.  I didn't think I could cum just from
pressing down.  Now I wasn't sure how I wouldn't cum from it.  But I didn't
want to get off.  Not yet.  I knew my sister had already orgasmed once, but
I could feel she had more to give.  I wanted to last as long as I could for
her.

   Darcy sat up for a moment and flipped my cock, so it was pointing
upwards.  Then she sat back down on it and draaaaaaggged her snatch against
it.  It didn't feel as good for me, but it seemed to do wonders for my
sister.  Her breath caught in her throat.  She smiled down at me, little
flutters of illicit pleasure popping off like flashbulbs behind her eyes.

   I rested my hands on Darcy's ass and squeezed at her cheeks as she
rolled back and forth.  The third time she did it, I felt my dick pop up
between her legs, and, for a moment, it kissed at her cunt.  But Darcy
lifted and guided my dick back into place.

   It happened again.  Darcy held me there longer.  Teasing me.  I could
feel the wet heat of her opening start to crown around my cockhead.  Then
she bounced back up and it was gone.

   The third time.  The third time my cock ended up right at her entrance.
Darcy tried to move but I held her hips in place.

   "Ethan you said you wanted to wait," Darcy said.

   "You feel really good," I said.

   "Ethan you said you weren't ready," Darcy said.

   "I know, I just..."

   Darcy started to move back.  For the first time in my life, I felt the
warm tightness of a vagina wrap around my dick.  My sister's pussy.  I
gripped Darcy's hips and held her there.

   "Condom," I croaked out.

   "I don't want to feel a rubber," Darcy said, "I want to feel you,"

   "Are you safe?"

   "I trust you," Darcy said.

   That was the second time she'd said that, in answer to that question. 
It wasn't the first time I wondered what she really meant by it.

   "It means I trust you to do what's right," Darcy said, "When the time
comes."

   She moved back.  It felt like being slipped into an impossibly tight,
incredibly slick, unimaginably warm place.  It was indescribable.  Imagine
spending your whole life incomplete, only not knowing it.  Then my sister
slipped my cock into her cunt and I realized what my life had been missing.

   "Whoa boy, go slow," Darcy said.  I hadn't realized I'd started
thrusting into my sister as hard as I could.  "It's been a while since I've
done this, I've never had a cock as thick as my brother's inside me, and I
want you to last.  OK?"

   I nodded.  I made myself put my arms behind my head and let my big
sister set the pace.  My dick inched inside of her, feeling better and
better.

   "Oh God that's GOOD," Darcy said.  "See I told you.  Something about
brother and sister makes it so much better."

   I couldn't speak from experience, only having been with one woman, but I
could confirm that nothing in the world had ever felt like this to me. 
Compared to being in my sister - my cock sliding inside as deep as it could
go - heaven would be a dim, dull place.

   Finally, I felt myself bottom out.  I looked down at where we were
connected.  My dark pubes sprouting up over her bare lips.  My cock, angry
and purple, sheathed in her pink snatch.  We were two separate beings
become one.  Siblings, connected in the one way we weren't allowed.

   Darcy gave me a nervous smile.  "OK?"

   "Amazing," I said.

   "Let me set the pace," Darcy said.  She lifted slightly off my cock,
then settled down.  As she did, her whole body stiffened, and her eyes
rolled back in her head.  My sister's chest and face flushed.  "Oh
fffffffFUCK!" she screamed.

   My sister slid back and forth.  Her snatch spasmed around my dick.  "Oh
fuck.  Oh fuck.  Oh fuck," she said.  Her fingers clenched white on my
arms. "Oh wow oh wow oh wow."

   I realized I was going to have to completely recalibrate my Darcy Orgasm
Scale.  What I'd previously labeled as a DOS 10?  That was more like a 4.5,
at best.  And we weren't even really fucking yet.

   Darcy leaned forward, her hair a silky curtain surrounding us.  She
kissed my lips.  Nuzzled my nose.  My sister came again, and I started to
wonder if I should dial 9-1-1 now or wait till she was done.

   "You OK?" I asked.

   "Holy fuck," Darcy said.  "I mean, holy FUCK.  You know?"

   I held my sister's hips as she rode me.  Every time she came, her pussy
got wetter, tighter.  I was already so far past the edge.  I had survived
nearly a week without cumming, after my sister had trained me to go
multiple times a day.  I'd never had sex, never experienced anything even
close to this feeling.  It was a miracle I hadn't already cum three times
already.

   "Squeeze my nipples," Darcy said, pulling me back to reality.  I reached
up and grabbed her cherry nubs.  "Harder."

   Darcy threw her head back and screeched.  Then she laughed.  Her
movements got faster.  More urgent.

   "Tell me," Darcy said.

   "What?"

   "You know what I want to hear so say it," Darcy said.  "You saw the
videos.  Hold my ass as tight as you can and tell me whose pussy you're
fucking."

   "Yours.  My sister's," I said, quickly correcting myself.  "Your
brother's cock is in your pussy."

   "Your bare cock," Darcy said, "Is in my cunt.  You're fucking your
sister."

   "You're cumming on your brother's dick," I said.

   "Yes," Darcy said, "Tell me.  Slap my ass."

   "You like fucking your brother?" SLAP.  "You love incest, don't you?"
SLAP.  "You're my sister slut, begging for your brother's cum." SLAP.

   "Oh YES!!" Darcy fell forward.  Her breaths came out in short, desperate
grunts.  "Huh.  Huh.  Huh.  Ohhhhhhhhhh."

   I wrapped my arms around my sister, remembering what we'd seen at Sam's
house, and flipped her over onto her back.  Darcy's eyes went wide with
lust and fear.

   I was in charge now.  I drove into my sister as hard and fast as I
could. Pounded her into our parents' bed.  She was no longer able to keep
even a modicum of control.  She screamed out, cursing and crying, while we
rutted together in bed.

   "Oh brother.  Oh bro.  Oh my brother is fucking me so good.  I don't
ever want to stop, E.  You're not going to stop.  Fucking.  Your.  Sister!"

   "Never," I agreed.  It was too good.  The woman beneath me too
beautiful. And then, finally, reality caught up with me.

   "Darcy?" I froze in place, buried deep in my sister.  One more movement
and I might...

   My older sister wrapped her legs around my waist and held me tight.  Her
pussy rippled up and down my shaft, hungry for what it knew it shouldn't
have.

   "You going to shoot for me, little brother?" Darcy asked, her voice
quavering.

   Just like that, I came inside my older sister.

   "OH!  OHHHHHHHH!  Oh fffffffffffffUCK that's so...  YEEEEESSSS!"

   I felt the pleasure explode out of me like nothing I'd ever experienced.
A gigantic burst of hot liquid that deluged her unprotected pussy in one
shot.

   "Yes, brother.  I feel it.  Your cum.  In me.  So hot.  So good.  Oh,
you're filling me UP!"

   I ejaculated again, an even longer gush.  My sight went dim.  An
incredible detonation of ecstasy blew through me from the bottom of my feet
to the tips of my hair.

   "YES!  Oh fuck I'm cumming.  Cumming so GOOOOOOOOOOOOD!"

   Distantly, I felt my sister thrash against me.  Heard her screams - a
running ramble of nonsense.  Our bliss was almost violent.  Both of us
battered down by the orgasm we shared.

   I shot inside my sister again and again.  Each time I felt it take me to
an ever-higher place.  Our bodies slick with sweat and cum.  Like riding
through an endless storm of ecstasy.  I felt my sister's pussy SQUEEZE my
dick.  Milk me for my seed.  Her nails cut into my arms.  Her legs crushed
the breath from my body.

   Suddenly the world went white.

   There was nothing.  No bed, no house, none of it.  Just this other
space. I felt oddly numb, like my nerves had overloaded.  I looked and my
sister was standing in front of me.  Her eyes as bright as I'd ever seen
them.

   "I love you," she told me.

   We were both back in the bed.  I covered my sister's cervix one last
time, one final burst of my fertile sperm, and both of us tumbled from the
peak of pleasure down a long, rolling hill, of warm delight.

   I slipped out of my sister, semen still leaking on her leg.  On the
sheets.  Darcy lay back, her thighs open like she was hoping I might come
back for more.

   I rolled to my side and rested my head on her chest.  Put my hand on her
belly.  Darcy turned and kissed me.  Her eyes searched mine.

   "Darcy," I said, unable to fathom other words in the universe.  "Oh
Darcy.  I mean.  Darcy.  Wow."

   My sister laughed at my nonsense monologue like she understood it
exactly.  She kissed me again.

   "I know," she said, "I know."

   *

   That was basically our weekend.  Occasionally we stopped to eat or use
the bathroom, but otherwise we banged pretty much nonstop until my parents
came home.  Oh sure, we did a little oral, just to change things up.  But
mostly it was my cock in my sister's pussy.  By Sunday night, there was
more of my seed in my sister's womb than some sperm banks will store in a
year.

   We did it in my parents' bedroom, on the kitchen table, and bent over
the living room couch.  In the backyard.  In the backseat of my sister's
Jetta.  In the back row of the movie theater (we went to a different one).
We were covered in rugburns, grass stains, and splinters (I did her up
against the backyard fence at one point).  My sister couldn't stand without
leaking like a busted faucet.

   Even at the end, with my parents' texting they were only ten minutes
away, I inseminated my older sister one last time in the shower.  We
couldn't stop.  We didn't want to.

   Finally, with my parents back home, though, reality seeped in.  I cooked
dinner and we ate (fully clothed for the first time in 72 hours) as a
family.  After, I did the dishes and went upstairs to my room.  I took out
my clothes and folded them on the dresser for work the next morning.  I
brushed my teeth.  Took out a book and read for a while.

   As my eyes started to droop, Darcy opened my door.

   "What the fuck are you doing?" she asked, playfully.

   "It's called education, sis," I said, "You should try it some time."

   "Moon Weasels from the Planet Mars is not education, just sci-fi trash,"
Darcy said.  She took the book out of my hands and tossed it across the
room.  What can I say, I still have a ways to go before I'm mature enough
for my older sister.

   "There's some stuff we need to talk about," Darcy said, sitting down on
the side of the bed.  I tilted my head, nervous.  "Sam texted me. 
Apparently, we owe her one for this past Wednesday."

   "And I guess I should tell you," I said, "Victoria's been texting me, as
well.  You want me to tell her to fuck off?"

   "We don't need to decide anything tonight," Darcy said, "Having an
'excuse' like Victoria could be handy going forward."

   "And Sam?"

   "I think you'll be happy with my solution, if it comes to that," Darcy
said, "Or, it may be something we never need to worry about." She let out a
big sigh and rubbed my head.

   "I'm going to miss having this time together," I said.

   "I'm not going anywhere without my brother," Darcy said, "In the
meantime, after this weekend, I doubt you need a goodnight workout."

   "How about a kiss?" I said.

   Darcy leaned in and pressed her lips to mine.  We didn't know it at the
time, but one of my more industrious little sperms had already broken into
my sister's waiting egg.  We weren't aware that life was subdividing itself
inside her womb.  We were oblivious to the fact that our incestuous union,
our shared sibling desire, had already been made real.

   I just reveled in my sister's touch.  Her scent.  The feeling of our
bodies connected.  Darcy snuggled up next to me.  I saw sleep slide across
her face.

   I kissed my sister's closed eyes and let her rest.  For a split second,
I was back in that other place, hearing my sister say those magical words.
"I love you."

   "I love you, too," I said.

   And only hoped that she could hear me.
