 Title: Sibling Revival-ry Ch.  01


Summary: My sister's a bitch, until that day in the shower.


Keywords: inc,fic



   My sister.  What can I say about my sister?

   Blonde.  Pretty.  Striking, huge blue eyes.

   Yep, that's my sister.  At eighteen, she was about 5'4", 120 pounds. 
Pretty athletic looking.  Actually, she looked just like Mom, although
Mom's tits were bigger, but not by much.  I looked more like dad, sort of.

   Yeah that's her.  My sister.  I loved her, of course, like a sister.  An
older sister.  Two years older.

   Yeah, that's my sister, Natalie, all right.

   What a cast iron bitch.

   For as long as I can remember, Natalie treated me like shit.  She took
sibling rivalry to an entirely new level.  If I did something to deserve
it, I could understand it, but I never went out of my way to be mean.  I
know you'd expect me to say that, but it's true.

   Really, it's true, because my earliest emotional recollection of my
sister is that I loved her.  Not brother-sister love, but real actual love.
I was five when I told my parents I wanted to marry my sister, which they
thought was cute, but I meant it, as much as a five year old can mean
anything.

   All of that, while she treated me like something stuck to the bottom of
her shoe.

   As we grew up, she was a constant thorn in my side, but it took a very
long time for my feelings about her to change .  Even when they did, they
never went all the way over the loathing line.

   ***

   The real trouble began when I turned eighteen.

   I'm a pretty big guy, carrying 215 pounds on my 6'3" frame, and I played
football in high school.  Since I was an athlete, I managed to get my share
of cheerleader attention, going out with several, and getting lucky with a
couple.

   I was trying to increase the score to three one afternoon.  The parents
were at work, and I had been able to convince Brenda, a cute little
brunette, to skip class and join me at home.  Things were getting pretty
hot and heavy, as I had divested her of most of her clothes.  Her bra came
off next, revealing a nice little pair of tits, which I was feasting on
when the shit hit the fan.

   "Well...  Isn't this interesting?" It was Natalie, being a bitch as
usual, standing in the doorway.  I hadn't heard her come home.  "Mom's
going to shit kittens when I tell her this!" She turned and left.

   "Come back here!" I yelled, chasing after her.  Brenda had been busy
working on me, as well, so I was down to my underwear, but couldn't just
let her rat us out.

   I guess Natalie hadn't expected pursuit, because I caught her not far
outside my door, tackling her to the ground.  I got the upper hand easily,
pinning her down under me by laying on her, and getting her flailing hands
under control by grabbing her wrists.

   "You're not going to tell anyone anything!" I threatened.  "I'll kick
your ass!"

   Natalie was on her back, looking up at me hatefully.  She struggled to
get free, but I was stronger, and heavier.  She was huffing and puffing,
her big boobs crushed under my chest.  I didn't see her next move coming.

   She craned her neck up....  and kissed me!  Hard, right on the mouth,
and since I was breathing hard as well, her tongue had no problem making
its way into my mouth.  I tried to pull back, but didn't want to let her
loose, so had to stay within range of her lips.  It took about fifteen
seconds before I decided I had to stop her, and released one wrist.  I
pushed her down, breaking away, and wiping her saliva off my mouth.

   She took advantage, grabbing my hair and managing to wriggle free.  I
let her go, stunned at the feel of her lips on mine.

   That's when I saw Brenda, standing there, watching.  She was clutching
her clothes in front of her mostly nude body, a look of horror on her face.


   "Ewww!" she gasped, "she's your sister, you pervert!" She pushed past,
and ran away.

   Oh shit, I thought, she saw Natalie kiss me!  And she thinks I was
kissing her!

   ***

   Just like that, I was screwed.  The next day, I had gone from somewhat
desirable jock to pariah in record time.  The sole consolation I had was
that the school year was almost over, only a couple of weeks remaining.  My
sister had successfully outed me, without even saying a word.

   I was furious.  Wouldn't you be?  My bitch sister had just ruined my
life, and I had to hide everything.  It's not like I could tell my parents,
could I?  Worse still, I couldn't even give her an appropriate punitive
response, because that would bring Mom and Dad into it.  I had to bide my
time.

   There was nothing I could do to explain away my problem.  No one would
believe me, anyway, as the first story always carries the most weight.  So,
if I was going to be damned for something I hadn't done, I might as well
let the crime fit the punishment.  Someone once said, 'there is no one so
free as someone with nothing to lose'.

   My opportunity came a couple of weeks after 'the kissing incident'.  I
was just getting home, and Dad was leaving, going out with the guys.

   "Your Mother will be home in about an hour.  Held up at work, I'm
afraid, but she said she's bringing pizza, so you're in good hands," he
briefed me, jumping in his car.

   "So, no one's home?" I asked, thinking I might get in a little Internet
porn before dinner.

   "Just your sister.  She's in her room."

   Ah....  So much the better, I thought, the time of retribution is at
hand!

   I went inside very quietly, creeping up the stairs.  Outside Natalie's
door, I could hear music inside.  I turned the knob, very carefully, happy
that it wasn't locked, and pushed it ajar, just a hair.  I stepped back.

   Bursting into the room, I surprised her.  She was trying on clothes, and
I caught her mid change, wearing just a bra and panties.  I hadn't seen her
in a bathing suit for quite a while, so I was astounded by her body, so
lean and lithe.  She screamed, of course.

   "Get out of my fucking room, you little bastard!"

   Right, I thought, almost a foot taller than you and nearly a hundred
pounds heavier.  'Little bastard' indeed.  You really need to update your
material.

   I closed on her, pushing her over on the bed.  If not for my previously
exemplary life, I would be treading on dangerous ground, invading Natalie's
privacy like this, but even if she told them, my parents wouldn't believe
it.  I pounced on her, and she struggled, but again, she was outmatched. 
During the struggle, her boobs peeked out of her bra, and since I had her
arms pinned, she couldn't remedy the situation.

   "Not so much fun when you're the one getting spied on, is it?" I asked.
She screamed again, and I put the pillow over her face, muffling the sound.
She struggled more.

   "Natalie....  Listen to me....  I'll move the pillow so you can breathe,
but you need to be quiet.  Okay?" What I took to be 'okay' came from
underneath.  I moved the pillow.

   She screamed again, and I buried her again.  Finally, she realized she
would have to cooperate, or learn to breathe through her toes.  I removed
the pillow again.  When I did this time, I saw her right breast was almost
completely out of her bra, and her left nipple was out in the open as well.
She had much nicer tits that I would have thought, with perky, erect
nipples.

   "You really fucked me up with that kissing stunt, you know?  Now I'm
'the guy who kisses his sister', and no one will talk to me, let alone go
out with me."

   "Get the fuck off me!" she snarled.  "What do I care?"

   I noticed her phone, within reach on the edge of the bedside table, and
picked it up.

   "Tsk, tsk, you left it unlocked, Does the camera work?" I threatened. 
"Selfies of your tits, sent from your own phone.  Definitely not socially
acceptable.  Mom will shit kittens..."

   "Okay, I give...  I'm sorry about what happened.  It wasn't my intention
to have it ruin your life.  I just needed to get you off of me, and it
seemed like the best way.  Can I cover up now?" she asked, glancing down at
her chest.

   "Um...  No," I replied.  "Your little stunt cost me a chance to get
laid. The least you can do is let me check out your tits." She struggled
again, only succeeding in making her situation worse.

   "Fine," she grumbled, resigned to her fate.

   "I gotta say, Nats...  They're pretty nice.  How big?" She glared at me.
"How's this camera work, again?"

   "Shit!" she cursed, "34DD." Her response was embarrassed, but also
proud.

   "Wow!  Really nice rack!  Seriously, Natalie," I said, honestly.  I let
her up, and she immediately grabbed the pillow to cover herself.

   "Thank you?  Am I supposed to take that as a compliment?"

   "Take it any way you want," I replied, walking out.  "We're not done
yet, Sis.  You still owe me."

   "The only thing I owe you is a knee in the balls!" she growled, slamming
the door, and locking it.

   Thus began the battle, with each of us trying to get to upper hand.  She
had spied on me, then I had seen her tits, which were really, really nice,
by the way.  I didn't expect her to give in, and the ball was in her court,
so I knew she would pull something.

   It took about a week.  I was in the shower, and felt the temperature of
the water change, going cold very quickly.  I exited, drying off and going
to investigate.  I found the washer running, full hot, with nothing in it.
Also the kitchen tap, and downstairs powder room tap.  Little wonder I
didn't have any hot water, and no question whose handiwork it was.  Natalie
was reading a book in living room, trying to hide her delight.  Fine.  My
serve.

   Her room was right next to mine, and our windows were side by side.  One
day while she was out, I rigged her window with some fishing line that
would allow me to slide hers sideways, opening it, from my window.  All I
needed to do now is wait for the weather I wanted.

   Two weeks later, clear nighttime skies made it very cold overnight, near
freezing.  The weather forecast had publicized it, so all I had to do is
unlock her window, and let her go to sleep.

   I would have liked to see her face when she woke up in a meat locker,
but her reaction when I did see her was worth it.

   "I don't know how you got into my room through a locked door," she
laughed.

   It seemed to signal a change in the course of events, as there was less
malice in the pranks.  There were lots of stolen towels during showers. 
She stole all my underwear once.  I tied all her bras in a knot.  She
short-sheeted my bed.  I hot glued her phone to the ceiling in her bedroom
and called her at two in the morning.  We were nothing if not creative.

   Then things kind of settled down for a while.  I was expecting her to
retaliate again, but nothing happened.  Days went by, then weeks, and she
did nothing, even treating me with more kindness than usual.  She was
lulling me, and it worked.

   I was in the shower, and my mind was filled with images of a hot blonde
getting ploughed by a black guy's huge dick, the last thing I'd seen on my
favourite Internet porn site.  There was a corresponding increase in blood
flow to my dick, and once it was good and hard, I conscientiously cleaned
it.  Okay, that's just a happy by-product ; I soaped up my cock and was
jerking off like a madman.  I didn't hear her come into the bathroom.

   Suddenly, the shower curtain flew open, and Natalie stood there with her
cell phone, recording video.  She caught me with a handful of soapy
erection.

   "Gotcha!" she laughed, but she got a surprise as well, arriving just as
I was spewing my thick load on the shower wall.  "Holy shit!" she hissed,
her eyes locked on my cock as I stroked it, unable to stop.  "I....  What
are you?....  I mean.....  Shit!....  I'm sorry!" Throughout it all, my
dick kept blasting white goo onto the wall, and she kept recording, finally
prying her eyes away and bolting out of the room about the time I was
finished cumming.  I was so stunned, I didn't even say anything, and my
knees shook in the aftermath of my climax, so it took me a few minutes to
rinse, dry off, and follow her.  She wasn't hiding, and I found her sitting
on her bed, the door to her room open wide.

   "Natalie," I began, planning a threat, but she held up her hand.

   "I know....  I'm so sorry.  I wanted to catch you naked, but not.... 
um....  doing....  that thing you were doing.  I apologize," she whispered.
Her demeanour led me to believe she meant it.

   "Okay, Nats.  Apology accepted," I replied, sitting next to her.  I was
still only wearing a towel, but no one else was home.  "I take it you'll
delete the video?"

   "Yeah," she said, handing me her phone, "go ahead." She smiled.  "Too
bad....  It's pretty hot.  I'd almost like to keep it....  Just for me....
For when I feel the need to....  you know."

   You watched it?  Again?  Already?" I asked, incredulous.

   "Oh yeah!  You've got a real nice cock, baby brother!" she laughed. 
"How big is it?" she asked.

   "You don't really expect an answer?" I retorted

   "Hey, you wouldn't let me off the hook until I told you my bra size,"
she said, snatching her phone back, "so tell, or I'll show!"

   "I don't suppose you'd believe 'I don't know' as an answer?"

   She shook her head.  "Not a chance.  Every guy I know has measured his
dick, so I'm sure you're no different.  Spill it."

   I sighed, beaten.  "Nine inches."

   "Yowza!" she gasped, "That'll do the job!  Pretty thick, too, from what
I've seen," she continued, thumbing her phone to start the video again.

   "Okay, that's enough," I growled, yanking the phone from her fingers.  I
saw my dick squirting on the screen before I hit the delete command.

   "Party pooper!" she giggled, pouting.  She caught the phone as I tossed
it back on my way out.

   ***

   "By way of an apology for my indiscretion the other day, I left you a
little something on your phone," Natalie said.  "Just keeping the field
level." She smiled at me and left.

   I fumbled with my phone, eager to get a peek at.....  whatever.  There
it was; a 45 second video recorded today.  I pressed play.

   Oh my god!  I thought, as the screen was filled with a view of what I
assumed was Natalie's crotch.  A landing strip of blonde pubes peeked out
from between her closed thighs , but the thighs didn't stay closed, parting
slowly until a very pretty pussy was revealed, pouting open like a flower.
Bright pink showed from inside, before two fingers entered the frame, and
opened the lips wider, giving me a view of her clit as well.  Just before
the screen went black, another finger moved in, and dipped into the wet
opening, trailing strings of moisture as it withdrew.

   "Holy fuck!" I groaned, immediately rock hard.

   I walked silently to my sister's room, where I found her laying back on
the bed, reading.  I said nothing.  She looked at me, and I kissed my
phone.

   "Why, thank you for the compliment," she laughed, before whispering,
"Now erase it.  I had to.  Now you do too."

   "Okay," I begrudgingly relented, doing so.  "Really nice, though. 
Really nice."

   I went back to my room, and closed the door.  My dick was still hard,
and I couldn't get my sister's pretty pussy out of my head, so I did what
most guys would do in this situation.  I pulled it out, and whacked off.  I
admit to feeling a little weird about doing it to thoughts of my own
sister, but it was either cum or explode, so I blew my wad into a tissue. I
did it again in the middle of the night, too.  Natalie's cunt had me
obsessed.  It was as I was stroking myself for the third time that night I
had an idea.  A way to get more.

   The next day, just after lunchtime, Mom went out to run some errands,
leaving Nats and I home alone.  She was sitting in the backyard, reading
one of her textbooks, when I walked up.

   "Sis, you you have your phone?" I asked, not really needing and answer.
I could see it sitting on the table beside her.

   "Yeah," she answered, handing it over.  "You're not going to glue it to
anything, are you?"

   "Oh no, I promise.  No glue," I said, taking it from her and turning
away.  I reevaluated that response and looked back.  "Maybe sticky, but no
glue."

   The look on her face was priceless.  Surprise gave way to confusion,
then outright lust as she pieced it together.  "Ooooooo!  Go bro!"

   Upstairs in the bathroom, I propped her phone up on some towels, facing
into the mirror, angled down slightly to keep my face out of the video,
since I didn't intend to force her to delete this one.  I took a deep
breath, and pressed record.

   I had stripped down to my underwear, so I began by peeling them down.  I
was still mostly soft, but the thought of my sister watching this while
playing with her slippery gash, was more than enough to get me hard
quickly. I gave her a profile view, as well as a front view, then got down
to it, squirting a little bit of Mom's hand lotion onto the head and
starting to stroke myself.  It wasn't long before I began to ooze a little
pre-cum, and I made sure she could see the drops as they appeared.  Despite
last nights abuse, I was pretty horny, and it didn't take long for me to be
on the verge of cumming.

   Part of me wanted to prolong it, showing how long I could last, but I
couldn't hold out much longer.

   "Gonna cum, Natalie," I growled, stroking faster.  "Uhn!  Yes!"

   A long rope of semen shot forward, nearly two feet, across the bathroom
counter, landing like a freshly painted highway line.  Another followed,
and a third, before the final drops left the counter looking like a Jackson
Pollock original.  Suddenly, a thought occurred to me, and I decided to
ratchet the lewdness up a notch.  I rubbed the head of my cock around the
counter, ploughing through the glop, smearing it about, and scooping up a
big dollop, which I let drip back off.  Finally, I turned the recording
off.

   I sat down heavily on the toilet seat, trying to catch my breath.  It
took me a few minutes to regain my composure.  I cleaned myself up, then
dealt with the countertop, even using Mom's spray cleaner to do a good job.
I dressed and left the room.

   When I walked out into the yard, Natalie was waiting impatiently,
watching me approach her.  I tossed her the phone.

   "Here you go.  Enjoy yourself....  I sure did," I laughed, flopping down
into the chair next to hers.

   A smile like none I'd ever seen crossed her face, a mixture of joy, lust
and anticipation.  She held out her hand expectantly.

   "Your phone please," she laughed, "tit for tat, as it were."

   "Yes Ma'am!" I gasped, quickly fishing my cell out of my pocket and
handing it to her.  She wasted no time, virtually running inside.

   Twenty minutes later, she was back, looking a little unsteady on her
feet, and a bit dishevelled.  She plunked down beside me.

   "Whew!  That was good!  I haven't cum like that for months," she
laughed. "Thanks, little brother!  Although, I guess...  given what I've
just seen...  I need to drop the 'little' part." She smiled and handed me
my phone back.  "Don't hurt yourself."

   This time, I was the one racing into the house, and up the stairs, into
my room.  I ripped my clothes off, jumped on my bed, and pressed play.

   The screen went from black to blue.  It took a few seconds for me to
realize that the blue was a big towel, spread out on Natalie's bed.  The
camera readjusted as thighs appeared on both sides, then again as the rest
of her body came into frame.  She was naked, laying on her back, with my
phone looking up her body from between her legs.  I could see her pussy in
the centre, her yummy tits at the top of the frame, but, as I had, she had
carefully positioned herself to exclude her face.  Her phone was in her
hand.  I was getting to watch her get herself off while she watched me
getting myself off, and got myself off.  If you think that's confusing, how
do you think I was feeling?  I was caught in a vicious cycle; lusting after
a very attractive woman, with a spectacular body, that just happened to
have my sister's face attached to it, hence the conflicted feelings.

   She was surprisingly vocal, commenting on what she was seeing on her
phone, and most of the comments were complimentary.  While one hand was
busy holding the phone, the other was visible pleasuring her juicy little
snatch, mostly rubbing tight circles over her excited clitoris.

   "Oh fuck, yes, stroke that big cock," she whispered from off camera, "Oh
yes, I'd like some of that!  Shit....  Yes!  Shoot that hot cum all over
me!" Her body twitched as her fingers went into overdrive, and she grunted,
stifling a scream of joy.  She finally wilted, and I was stroking my
rejuvenated erection as I watched her big tits quiver with her ragged
breaths.  I figured the show was over, and was just about to restart it
when her fingers dipped deep into the pink crevice that dominated the
frame, coming out visibly wet.  The fingers disappeared, and a moan of
delight was heard, along with what were obviously sucking noises.  The
fingers went back several times, repeating the process as my sister licked
her own pussy juice from her fingers, and I jerked furiously.

   One more surprise awaited.  Her left hand started to circle her clit
again, while three fingers of her right hand ploughed her gaping wide cunt.
She plunged them, full length, into herself, slowly at first, then in an
ever increasing rhythm that made her big tits jiggle wildly in the
background.  She was moaning, quite loudly, and her fingers were soaked
with her juices, making slurping noises as she frigged herself like a
maniac.  Somehow, her left hand kept doing the circles on her clit, the
masturbatory equivalent of patting your head while rubbing your stomach.  I
had no idea she was so coordinated.  Then she did something else I had no
idea she could do.

   Natalie squealed, her fingers an absolute blur on screen....  and she
squirted!  Drops of presumably delicious pussy juice flew about as she kept
fucking herself, having added her pinky finger as well.  A final, guttural
moan of orgasmic agony signalled her peak, and she yanked her hand out of
her abused cunt quickly.  This time, the squirt wasn't a flurry of
drops.... It was a gushing stream, that almost inundated my phone!

   Seeing my sister's cunt spasming and squeezing out a stream of sticky
ejaculate was more than I could take, and I came too, sending arcs of my
own white goo flying through the air.  It landed everywhere, and I kept
stroking, until the chamber was empty.

   Back on the screen, Natalie's naked body, soaked in sweat, had resumed
normal breathing, and she sat up, her beautiful breasts vanishing from
view.

   "That's for you, little brother," she whispered, "and thank you for my
gift, as well.  I'll cherish it." Fade to black.

   Cleanup took a while.  I hadn't been as proactive as she had, so I had a
bigger mess to deal with, but I managed, flushing the evidence, a luxury
Natalie didn't have.  Rifling through the laundry hamper, I found the blue
towel that she had used.  Since she usually did the laundry, I guess she
wasn't too concerned with someone else finding it.  She'd buried it at the
bottom, but that was the extent of her camouflage.  It wasn't really
necessary to give it a close sniff, as it was soaked with pussy juice in
several spots, and had quite the scent, but I did sniff it....  and taste
it!  She was delicious.  I almost wanted to keep the towel as a souvenir,
but put it back where she'd left it.

   I admit, I wasn't very steady on my feet as I rejoined her in the
backyard, in much the way she had been.  She looked at me and laughed.

   "Did you cum again?" she giggled.  "Already?"

   "Watching that?" I asked, rhetorically, "Oh yeah.  Probably later, too.
It was pretty impressive!" Suddenly, talking sex and masturbation with my
sister was normal.

   "And exhausting," she laughed.  "Satisfying, but exhausting."

   We heard Mom inside the house.  She was back, and we had finished just
in time.  We looked at each other and smiled, both of us rising wearily
from our chairs and heading inside.  Natalie went on laundry duty, while I
helped with dinner.

   I guess you could say that Natalie and I had worked out our differences.
Somehow, I don't think our parents would approve of our methods, but what
they didn't know wouldn't kill us.

   ***

   The next few weeks were fun.  We didn't do anything else, each of us
seemingly satisfied with our respective video voyeurism.  What we did do
was give each other subtle little compliments that indicated our delight.

   For example, one day, we passed each other in the hallway, just outside
her bedroom door.  She stopped me, leaned against the wall and rolled her
eyes, silently mouthing "Wow" and "Thank you".  Another time, she was
walking into the den, where the whole family was watching TV.  I wagged my
phone at her, and smiled.  She surprised me by sitting next to me on the
couch, and actually snuggling against me a little.

   "Today?" she whispered.

   "Twice," I whispered back.

   "You're welcome," she smiled

   Eventually, the appeal began to wane, or maybe we just wanted more of
the same.  Either way, I didn't know what to do.  It seemed like we had
reached the end of what we could do, without crossing the line.  I had to
admit though, 'the line' was getting a little blurry.  Every time I watched
my sister's pussy spraying in orgasmic bliss, it got a little fuzzier.  I
had no idea at the time, but I wasn't alone in this feeling.  I was the one
that brought it up, however.

   I walked past Natalie's room.  Our new relationship meant that our doors
were often open, unless we were otherwise occupied, and this was no
exception.  She was in there, reading, as she usually was, when I stopped,
leaning in her door frame, gazing at her.  She stared at me for a few
seconds, finally speaking.

   "You have something to say, or are you just going to stand there?"

   "I was just wondering what was next," I said quietly, as there were
older ears around tonight.

   Natalie smiled, and sat up, waving me in.  I sat next to her.

   "How about a live performance?" she whispered.  "Obviously, not now, but
maybe the next time everyone else is out?  No touching, just, you know, in
the same room.  Or would that be too weird?"

   "Nats, I think we passed weird a while back," I laughed, as quietly as
possible, "but I'm game if you are.  Deal?" I asked, holding my hand out.

   Natalie looked at my hand and giggled.  "I've seen what you do with that
hand, remember?  Have you washed it since the last time?" I threatened to
rub her face with it, and she laughed again.  "Okay, okay," she relented,
taking my hand in hers and shaking it.  "Deal.  Ooooooo, your hand is
soft....  I guess Mom's hand cream is working!"

   She got me with that one, I had to admit, and I laughed, leaving without
a return volley.  My sister had just agreed to finger her pussy for me,
live and in person!  I wondered how long I'd need to wait for the
opportunity.  Until then, I'd make do with the video version.

   ***

   Three days.  Three long days.  That's how long we waited.  Finally, both
Mom and Dad were out for the evening, separately, but gone.

   Dad had left about twenty minutes ago, and I was watching Mom's car pull
out of the driveway when Natalie walked up beside me.  She watched silently
for a few seconds.

   "Where?" I asked.

   "My room.  Five minutes," she said, high-fiving me and racing upstairs.

   My hands were shaking, I was so excited.  I stared at the clock until it
finally, mercifully, indicated the requested time had elapsed.

   When I rounded the corner into Natalie's room, she looked as nervous as
I felt.  She also looked beautiful, having changed, brushed her hair, and
even put on a little makeup.

   "Hi," she said.

   "Hi," I replied.  The silence was awkward.  "How do we start?"

   "Well, how about we strip for each other.  One piece at a time?" she
offered.

   I did a quick inventory, coming up one piece short of what she was
likely wearing.  "Okay, you start."

   "This was a lot easier on video," she laughed, slowly peeling her tight
t-shirt up over her head.  Victoria's Secret in blue supported her boobs,
holding them up and out.  "Your turn."

   I pulled my shirt off, having got the better of round one, as I often
went without a shirt anyway.

   "I have a feeling I've been had," she giggled.  "I've seen that much
before, but I've got to say, you're built pretty good, little brother.

   "Thank you, Natalie," I replied, putting my hands behind my back.

   "Me again?" she asked, unsnapping her shorts.  She grinned, and turned
her back as she wriggled out of them, bending from the waist.  A thin
string of matching blue divided the cheeks of her firm ass, and I couldn't
suppress the groan that slipped from my lips.  She stood again, stepping
out of her shorts, and turning to face me again.  She looked incredible in
her matching bra and thong.  "I'll take that as a compliment!" she smiled,
rocking on her toes nervously.

   My shorts hit the floor, leaving only my jockeys to contain the erection
that had started to grow.

   Natalie licked her lips.  "No turning back now," she whispered, reaching
behind to undo her bra.  She let it slide off her shoulders, leaving me
awestruck.  My sister was built!  I know I'd seen them before, when I first
retaliated, and again on my phone, but somehow, the fact that she was
showing me her tits voluntarily made it better.  She had some really nice,
round, full DD titties, and I was staring.  "Ahem," she laughed.

   "Okay," I said, skinning my underwear down.  I wasn't fully hard yet,
but I wasn't soft either, hanging heavily.

   "Wow!  It looks bigger in person!" she gasped.

   "So do those," I laughed, waving to her big boobs, which now had very
tall, erect nipples on them.  Whether it was cold or my cock on display,
something had perked those points up to impressive heights.

   She dropped her thong without a word, moving over to the bed, where she
had spread the blue towel out again.  She sat back against the headboard,
and pointed to a pile of pillows on the foot of the bed.

   Take your place," she said, tossing a tube of lubricant over to me as I
did.  She spread her legs.

   Well, that did it!  As soon as I saw that pussy again, my dick stood up,
rock hard in seconds.

   "Whoa!" she gasped.  "Now that's what I call a cock!  Holy fuck, little
brother...  If I'd have known you were packing that, I never would have
interrupted you with that little brunette, what's her name?  "

   "Brenda, " I answered.  "Don't remind me."

   "Yeah, well, I'm sorry about that....  She probably would have loved
that thing in her pussy!" she giggled.  Her fingers were now busy diddling
her clit.  "Come on...  lube up and stroke that big fucker for me!"

   Apparently, when Natalie gets excited, she's a dirty talker.  Hearing my
sister discussing my private parts with such obvious lust was a new one,
and I have to admit that I liked it.  I squeezed some gel onto the head of
my dick, and started to flog myself.

   We went at it in silence for a minute or so.  Well, relative silence,
anyway.  She was moaning and her pussy was squishing, and that started me
moaning too.  She scooted down a little, raising her legs higher, then
hooking her elbows behind her knees.  Her cunt gaped open wider.  She had
taken some ballet when she was younger, so maybe that accounted for the
flexibility.  Whatever the source, this position drove me wild.

   "Fuck, Nats!  Your pussy is beautiful!" I grunted.  "Seeing you like
that is so hot, you're going to make me cum!"

   "NO!  Not yet!  We have to cum together!" she cried.  "I'm getting
close....  Stroke it good for me, little brother.  Let me see you jerking
that big cock, all shiny and wet!"

   I slowed down, trying to stem the tide, while she sped up, now jamming
four fingers into herself while trying to set her clit on fire.  The
fingers in her cunt were hooked deeply.  As close as I was, maybe two feet
away, I could see her juices oozing up around her intruding digits.

   "Oh fuck yes!  I'm gonna cum!  Stroke your big cock for me!  Shoot it
while I cum!  Do it!  Ahnnnn!  Yes!"

   Natalie shrieked.  A trickle of pussy juice ran out of her cunt, and
dripped down her ass crack, before she wrenched her hand out.  I was
pounding my cock mercilessly.  She watched me and shrieked again, spraying
her juices like a garden hose.  Because her pussy was angled up, in this
position, cum bubbled up like a drinking fountain, some of it landing on my
cock and stroking hand.  That set me off like a firecracker, and a long
rope of jism flew out, reaching just far enough to drip down her ass. 
Another followed, but didn't have the range, landing on the towel to mingle
with her copious discharge.

   Both of us gasped for air, winding down from our respective
earthshattering orgasms.  Natalie un contorted herself, her legs landing
either side of me.  I watched her pussy drip onto the towel.  It was
minutes before either of us could speak.

   "Natalie, do you always squirt like that?" I asked.  She brushed the
hair out of her eyes and took a deep breath.

   "God, no!  It'd kill me if I did!  Not to mention the mess.  No, it only
happens when I'm really, really excited.  I squirted on one guy, and he
left....  Just got up, and walked out.  Maybe he thought I was pissing on
him or something." She dipped her fingers in her pussy, then licked them
clean.  "His loss," she smiled.

   I licked the spray from the back of my hand.  "Mmmm Mmmm." I moaned.

   "More?" she giggled, dipping her fingers again and holding them out for
me.  "There's plenty?  "

   She was right about that, and it was delicious.  She fed me several
fingers full.

   "We'd better clean up," she said, sitting up.  She clenched her pussy,
forcing the last excess juice out onto the towel.  "Whew, it smells like a
brothel in here.  Open the window, will you?"

   Just like that, it was over.  Sure we walked around naked for about
another hour, washed the towel and sheets, had separate showers without
closing the door, that sort of thing, but as soon as my dick began to rise
again, from watching her wiggle and jiggle around, Natalie shooed me away
and got dressed.

   Just before Mom was due home, Natalie found me watching TV.  She plunked
down next to me on the couch.

   "Thanks, bro....  That was fun.  Obviously, we can't go crazy like that
all the time, but I'd like to do it again.  How about you?"

   "Shit yes!" I gasped, a little more enthusiastically than I'd planned.
"I thought you were pissed at me, the way you chased me out of your room."

   "Men!" she laughed.  "No, I wasn't pissed.  Pooped, yes....  Pissed, no!
An orgasm like that takes a lot out of a girl, you know?  Besides," she
whispered kissing me on the cheek, "you were getting hard again, and I
couldn't trust myself around that big dick.  I might have done
something.... wrong." She smiled, and left.

   I sat there, digesting the last bit of the conversation.  Did my sister
just say she wanted to fuck me?  My dick was like steel.  But that's wrong.
But my dick was like steel.  I can't have sex with my sister!  Sure you
can...  Did you see that pussy?  Those big tits?  And what about the
squirting?  Don't you want to drink your fill of her sweet, sweet nectar?

   My brain was short circuiting.  I knew which way my dick was voting, but
my other head was having a hard time with the whole 'incest is taboo'
thing. Maybe I misunderstood her.  Yes, that's what must have happened.  A
simple misunderstanding.  Boy, I'm glad I figured that out.  Could have
been really embarrassing.  Case closed.

   Then why was my dick still hard?
