 Title: My Sister's Potion


Summary: My sister and I test a love potion with unexpected results.


Keywords: inc,fic



   I never expected to catch my sister masturbating.  It was crazy, as if
she wanted to be caught, which didn't fit her personality.  I found her
lying naked on the couch in the family room with her torso twisted so I
could see everything she was doing.  She had two fingers deep inside her
pussy.  Reaching behind herself, she used a finger of her other hand deep
inside her ass.

   Standing at the end of the couch, I gawked at her.  "What the fuck are
you doing?"

   "Getting off," she gasped, furiously fingering her two holes.  Her
clothes were in a pile on the floor.  The TV was off.  I didn't see her
computer, tablet, or phone.  What she was doing felt wrong.  The lack of
any reason for her to be doing it felt even odder.  It felt inexplicable.

   I followed one stupid question with another, "Why?"

   The desperate expression on her face chilled me as much as the helpless
tone in her voice.  "Because I have to."

   "Says who?" I asked, unable to stop staring at her nudity or the
explicit ways she fingered herself.  She didn't stop or try to cover
herself like you would expect when getting caught in a compromised
situation.  It felt surreal.  Was she high?  Drunk?  None of it made sense.

   "The voices," she groaned as a wave of pleasure contorted her face.  Her
eyes fluttered and her mouth hung slack as she began moaning.  She wiggled
and squirmed against her fingers, forcing her fingers deeper inside her
pussy and ass as she shivered with an obvious orgasm.  "Oh God," she
groaned and began sucking on the finger that had been up her ass.  She
instantly replaced it with the two fingers that had been in her pussy as
she blushed deeply.  Finally, it looked as if she was done.

   Carol sat upright without trying to cover her nudity.  I suppose it
didn't matter at that point but it felt strange seeing her sitting naked in
the family room.  Her face was beet red with how embarrassed she felt, but
she didn't move.  I became aware of the hard-on growing inside my shorts. I
did my best to ignored it even though it felt kinked and I would need to
reangle things if it decided to keep growing.  "Do you want to get
dressed?"

   "Yes," she said without moving.

   How she sat there blushing without moving made no sense.  Her nipples
were clearly hard and I watched her chest rise and fall as she continued to
breathe deeply following the thrill of her orgasm.  I ran through the only
list of conditions that made sense to me.  "Are you drunk?  High?  On
drugs?"

   Looking mournful, she shook her head.  Her eyes moved directly to my
crotch.  In a pitiful voice, she begged me, "Please don't get hard and if
you do, don't let me know it."

   I struggled with ignoring where she was looking, but I couldn't stop
looking at her open nudity.  While I would never admit it out loud, Carol
was hot in that unattainable, untouchable way.  She had always maintained a
prim and proper attitude that shut down lecherous comments before they were
ever spoken.

   The joke was that my sister had "resting pleasant face" instead of a
"resting bitch face." She radiated goodness and wholesomeness.  Her
naturally golden blonde hair never needed the addition of lowlights or
highlights.  The sun would kiss her hair with extra color.  Her straight
teeth glistened white from good oral hygiene.  She ate like a bird and
claimed that working as a daycare teacher was more than enough exercise for
her.  She radiated an aura that made people want to sit up straighter, mind
their manners, and be nice to animals.  Seeing her naked and glistening
with perspiration from her frenzied orgasm felt as wrong as painting a
mustache on the Mona Lisa.

   I resisted the growing need to adjust my junk.  Carol might be a sweet,
innocent angel to the rest of the world, but she was my big sister and my
frequent tormentor.  I had grown up as the shadow to her radiance.  Where
she could do no wrong, I seemed to be a constant sad sack.  I felt like the
runt of a two dog litter.  Unlike the rest of the world, I had seen her at
her worst.  I had heard her belch, whine, and complain like a snotty brat.
I had felt her wrath as she laughed at me for being a loser.  Still, she
was my sister and despite our history, I could tell she was in distress. 
"What is wrong with you?"

   "Nothing," she said, still staring at my crotch as she replaced her
lost, worried expression with an impish smile.  She clutched at her
breasts, pulling and tugging on her swollen nipples.  She glanced up at me,
flashing that pretty smile that could make the grouchiest stranger smile
back.  "Pull it out and I'll suck it." Her voice sounded funny as if she
was being forced to say the words through a smile she didn't want to
display.  The difference was in her eyes.  She looked at me with her big,
blue eyes held wide open in shock and surprise.  The look in her eyes
didn't match her smile or her words.  She went back to staring at the front
of my shorts, licking her luscious lips with her tongue.

   "Not until you tell me what's going on."

   After blinking, she gave me a look of genuine appreciation.  It took me
a moment to recognize the expression, I had seen it a few times on her
face. "It's a spell," she said in her voice.  "Technically, a potion.  I
can't help myself."

   "Cut it out," I snapped, rolling my eyes.  "Tell me the truth."

   "I am," she moaned.  "And I can prove it." She glanced mournfully at her
clothes without moving to collect them before she stood.

   "Do you want to get dressed?"

   "Yes," she said in a flat tone, once more sounding drugged.

   "Why don't you?"

   "I can't, not yet.  The potion." She sounded like Carol, but I could
tell the words were difficult for her to say as if she had to force them
out of her body.

   "Right, a potion.  I thought you said it was a spell?"

   "The potion is the spell," she said, moving towards the stairs to the
basement.

   Playing along, I followed her.  "And how long does it last?"

   "I don't know yet," she said in her forced Carol voice.

   While I had no idea why she was acting like this, I wasn't going to
start believing in spells and potions, not one word of it.  I couldn't
explain her nudity or open masturbation, not yet, but what the hell, right?
Walking behind her, I took the time to adjust my prick without her seeing
as I stared at her tanned, bare ass.  "Is it fading?"

   "I think so," she said, dropping a bit of the forced tone in her voice.

   Our basement is divided down its middle.  At the foot of the stairs,
it's finished and furnished with a wet bar that's always locked, a big
screen TV, and a massive sectional sofa for movie nights.  Our parents
referred to this room as the Media Room.  Carol and I referred to it as the
Party Room.

   A single door in the dividing wall opened into the unfinished part of
the basement.  In that dark, damp space was meticulously labeled boxes
filled with decorations for every holiday and old treasures too valuable to
the family for the trash.  A single fluorescent light fixture illuminated
the space.  Carol flipped the switch after opening the door and revealed
her handiwork.

   Boxes were pushed against the walls, leaving a large open area of bare
concrete.  In the center of that open area, she had drawn a double circle
and pentagram that looked like something out of a cheesy horror movie. 
Black candles stood at each point of the five-pointed star.  Three TV tray
tables were set-up with a variety of little bottles lined up in a row.  I
recognized the bubble-shaped bottles.  They had come from that goofy
witchcraft store near the edge of downtown.

   "Nice try," I laughed, walking around the circle within a circle to
inspect the bottles.  None of the bottles were labeled, but she had Post-It
notes in front of each with instructions written in her tight, tiny
handwriting.  "Which one is Eye of Newt?"

   "Ha-ha," she deadpanned, sounding more normal.  "None of them." Moving
behind the row of tables and pointing left-to-right, she listed off the
names of each one.  Most of them held spices or herbs.  A few were
supposedly filled with the essence of various weeds.  Nothing she listed
sounded like a drug or poison.

   "So you mixed these together and got high?  Like some sort of herbal
Viagra?"

   She shook her head.  "There's a spell, too, and can you stop looking at
me like that?"

   "Hey, you're the naked one."

   "I told you, I can't help it."

   I spied a clear flask sitting in the middle of the center table. 
Picking it up, I swirled it around and examined the translucent amber
liquid.  Flakes of something floated in the mixture.  It was easy to guess
this was the finished product.  "How much of this did you take?"

   "One drop beneath the tongue."

   "And then what?"

   Shrugging, Carol self-consciously draped one hand across her breasts
while holding her other over her pussy.  "Can I get dressed now?"

   "Are you asking me?"

   She shook her head, looking as if she was listening for something. 
Seemingly satisfied, she moved to the open door.  I followed her back
upstairs.  Fishing through her clothes, she kept her back to me as she
pulled her panties, shorts, bra, and tank top.  When she turned back
around, she looked like my sister again.  "You can't tell anyone about
this."

   "About what?"

   "Any of this," she said, collapsing on the couch in a heap.  "I can't
believe I did that."

   "Me neither," I said, sitting on the far end of the couch.  "Though it
was pretty hot.  I didn't know you were into anal."

   Her cheeks turned red.  "I'm not.  I've never done that before."

   "Uh-huh," I scoffed.  No one shoves a finger that far up their butt if
they've never done it before.

   "I'm serious," she insisted, clearly distressed.  "That stuff, that
potion, it made me do it." I reminded her about hearing voices and she
seemed confused.  "Not voices, exactly.  More like urges, like unspoken
suggestions.  Like when you start craving chocolate and you can't stop
until you get some."

   "And you suddenly craved masturbating where I would see?" I asked.  I
shook my head, unable to believe a word of it but unable to explain a
moment of what I had witnessed.  "You know, if you want to be a perv, go
for it.  I promise I won't tell Mom or Dad, but damn, Carol."

   "You don't believe me," she pouted.

   "How can I?  I mean, I always suspected you were secretly a freak, but
this is crazy talk."

   "Fuck you," she groaned in a very Carol voice despite using a phrase few
would believe she knew.  "Which is easier to believe, that the potion works
or that I wanted you to catch me doing that?"

   Oddly, she had a point.  Like I said before, Carol had an aura that kept
people in check around her.  Maybe it had something to do with her resting
pleasant face, I don't know, but I knew my friends could say the rudest
things about her until she was in the room and then it was as if a spell
came over them.  Being her brother, I had always felt immune to her aura.
Like I said before, I had seen her at her worst.  While the world thought
she was a virgin princess, I knew she could swear, fight, scratch, and be a
real bitch.

   "Then prove it," I suggested.  "Take some more and let's see what
happens."

   "You do it," she said.  "It supposed to work equally on men and women.
You do it and let's see what happens."

   "No way," I said, marveling that she thought I would be that stupid. 
"What did you really put in that bottle?  Jalapeno?  Cayan Pepper?" Carol
knew I hated hot stuff.  Once, when we were kids, she dared me to put a
handful of Red Hot candies in my mouth for sixty seconds and I couldn't
last longer than five seconds.  While this felt an extreme set-up for a
practical joke, I still didn't trust her.

   "I swear it's not hot," she promised.  "It doesn't taste like anything.
You just put a single drop beneath your tongue, that's all."

   "What's it going to do to me?"

   "I don't know.  Maybe it'll make your clothes fall off like mine."

   "That's what I'm afraid of," I said, more afraid of her pranking me into
putting something hot and spicy in my mouth.  Unless you know me and the
number of times she'd had pranked me during the years you can't appreciate
how much of a phobia I had about that.

   "What if we dissolve a drop in a glass of water or something?  Then,
even if it is hot, you won't taste it."

   "I thought you said you had to put it under your tongue?"

   "I should still work," she said with an easy going shrug before turning
on her charm.  "If you do it, I'll do it again and who knows what will
happen if I do?"

   Seeing her in full perv mode did sound enticing.  I shook away that
thought because I knew nothing would happen.  While I couldn't see it yet,
she was pranking me.  While I couldn't figure out how she was doing it or
why the pay-off at the end had to be damn big if she was willing to
humiliate herself as she had done.  In spite of my skepticism, I found
myself asking, "How long did its effects last?"

   "About an hour," she said with a smirk.  She had already worked out that
I was going to do it.  While I hemmed and hawed about it, she ultimately
turned out to be right.

   Before I would do it, I made her show me everything from the book where
she had found the love potion (lust potion is more like it) to carefully
revealing the contents of each bubble bottomed glass jar.  Working my
tablet as she described each one, I searched for side effects and any
flavor profiles each ingredient had.  Finally convinced nothing had a spicy
or heat profile, I opted to try a single drop without dissolving it in
water.

   Holding the pipette with my finger over the open end, I had more
question before I risked it.  "How long did it take to kick in?"

   "Almost immediately."

   "What if I try to do something to you?"

   "Plu-eeze," she groaned, rolling her eyes.  "I think I can still take
you." Regretfully, I knew she was probably right.  Carol might be a girl,
but she was stronger than she looked and I'm a bit of a wimp.  Could I help
it if we had the same genes?  Isn't it funny how being lean could translate
into strength for her while I was just skinny and weak?

   After sniffing the end of the pipette, I opened my mouth, lifted my
tongue, and released exactly .05 milliliters beneath my tongue.

   I know she said it would take effect immediately, but I didn't feel
anything except relief that it wasn't spicy hot.  As she had described,
there didn't seem to be a taste to the liquid.  Offering her a shrug, I put
down the pipette and went upstairs to the family room.  I didn't feel dizzy
or foggy headed and I certainly didn't hear any voices in my head, though I
did feel sort of horny.

   With each step upstairs from the basement, I felt my prick growing
harder and harder.  Okay, so that felt sort of strange, except I'm a guy
and I'm used to having erections happen.  Guys understand that we can't
always control them.  I dismissed the sensation as being triggered by the
memory of how I had found Carol naked on the couch with fingers buried in
her pussy and one up her ass.  That's all it was, right?

   Walking into the family room, another idea occurred to me.  If Carol was
a believer in this potion, didn't that give me the ability to prank her? 
What if I showed her my hard-on?  Would it matter or did the bullshit of
taking her potion give the perfect cover for doing it?  Facing her, I
gripped the front of my shorts and showed it off to her.

   "See?  It's working!" she giggled.

   "Yeah, it is," I said, rubbing my hard cock.  Damn, that felt good,
really good.  So did sticking my hand inside my shorts and really touching
it.  So did pushing down my shorts and underwear so she could see it.

   Carol laughed at me getting naked.  "What are you doing?"

   "It's the potion," I assured her, playing along as I pulled off all my
clothes until I stood in front of her completely naked with my massive
hard-on throbbing in front of me.

   "Damn, bro, you're hung."

   "You never guessed that?" I asked, proudly displaying my fully erect
cock to her.  I wasn't porn star sized, but when I got this kind of hard, I
knew I was close to eight inches in length.  Showing it off to her felt
good, really good.  I still didn't see the payoff to her prank, but it felt
good believing that I was pranking her back.

   "I bet if you shaved you would look even bigger."

   Leaving my clothes on the floor of the family room, I walked upstairs to
the bathroom in the hall that we shared without a second thought with her
following behind me as if I was the Pied Piper.  I felt the big smile on my
face as I entered our bathroom, fished in the drawer for the scissors she
used to trim her bangs and began snipping away at locks of my pubic hair. I
trimmed away as much hair as I could before using her razor to shave my
cock and balls while she giggled and watched me do it.  I even shaved my
ass which made her laugh even harder.  I laughed with her, enjoying every
moment of trying to make this is awkward as possible for her.

   Shaved smooth made every touch of my cock and balls feel even better. 
Glancing down at myself, I did look bigger.  As a matter of fact, it looked
sexy as hell seeing myself shaved.  Why hadn't I done this sooner?  Being
smooth felt good, really good.  So did being naked and hard in front of my
sister.

   "How's your butt feel?" she asked, clearly enjoying seeing me naked and
bare.

   Licking my finger, I experimentally caressed my smooth ass and
discovered that felt good, too, really good.  Wrapping my hand behind my
back, I pushed the tip of my wet finger in my ass.  Mm, that felt good, but
my finger needed to be slippery.  I sucked on my finger for a moment,
enjoying the shocked expression on my sister's face before pushing my
finger deeper inside my ass.  Yeah, that felt good, really good, but I
needed more spit.  I repeated the gesture, licking and sucking on my finger
once more before working it all the way inside of me.

   My cock ached and throbbed as if I had just spent two hours playing
kissing and groping games with my girlfriend.  I felt like I had the worst
case of blue balls in the history of mankind.  I needed to get off really
bad and told her as much.

   The suggestion she made felt funny.  Deep inside, it felt wrong, as if
her prank was being revealed to me, but I was helpless to refuse the idea.
"You should try to cum in your mouth." I blinked hard, remarkably excited
by the idea but unsure how to do it.  She must have seen my confusion.  She
suggested I lay on the floor and put my legs over my head.  "Then it will
be aimed right at your mouth."

   Moving to the floor, I lay on the soft throw rug in front of the bathtub
and curled into a ball as my sister had suggested.  I made sure my head
faced the doorway so that once I had my knees over my head, she would see
my upturned ass and see my finger fucking my puckered hole.  Tugging and
pulling on my hard cock, I wished I could suck it.  I tried reaching it,
sticking out my tongue without getting close enough.  Fuck.  I wanted it.

   Glancing upwards, over my head, I made sure Carol still watched.  For
some reason, her watching me felt very important.  Staring upwards at my
cock, I wondered why I had never thought to try this on my own.  My cock
throbbed with its need.  I could feel a massive orgasm welling up inside my
balls as I realized how much I wanted to do this.

   Carol had described hearing voices, but it wasn't a voice like someone
talking to you.  It was more like an internal dialog of thoughts, ideas,
and suggestions.  She had described it as a craving, but that didn't come
close to describing the sensation.  It went past craving and into feeling
like a need I couldn't control.  I had to get off.  I didn't have a choice.
I had to get off or I might die of sexual frustration.  I needed this as
much as I had ever needed anything else in my life.

   Helpless to stop, I stroked my cock while alternating my gaze.  I kept
looking at her and then my cock aimed at my face before looking back at
her, too.  She was going to see me do this.  She was going to see me
jerking off, fingering my ass, cumming on my face, and eating it.  I
already knew I would do that.  I already knew I was going to eat my cumshot
in front of her and I couldn't stop myself.

   My mouth stretched open and I stuck out my tongue all the way as the
first massive spurt erupted from my aching cock.  The long, thick, ropey
glob of creamy white cum splashed directly on my tongue and began rolling
slowly down my throat even as it followed with another splash of ejaculate.
This was the orgasm I craved, the one I needed.  I felt my asshole clamping
down on my finger, encouraging me to cum more.  Spurt after merry spurt of
cum flew from my cock in copious amounts I had never generated before that
moment.  The first couple went inside my mouth before my jerking hand had
the rest pasting my face from forehead to chin.

   When it was all said and done, I scooped up a final droplet clinging to
the slit of my prick and licked my finger clean.  Next, I licked the finger
that had been in my butt, feeling wildly empowered.  Finally, I stood and
looked in the mirror to admire my cum-splattered face.  I smeared the cum
across my face before realizing what I really wanted to do.  One fingerful
at a time, I scooped it off my face and ate it.

   Carol had moved behind me, grinning wildly as she watched me cleaning my
face.  "Told you," she giggled.

   I tried to say something to her and couldn't, I was too busy cleaning my
face for words, but I saw the look of panic in my reflection.  My eyes
looked as hers had, desperate and panicked while the rest of my face looked
like I was scooping ambrosia off my cheeks, the bridge of my nose, and my
forehead.

   Turning to face her, I clutched at my still hard cock, inviting her to
look at it.  "Let me eat your ass," I said in a voice that felt strange,
foreign, and far away.  "I want to stick my tongue as far up your sweet ass
as I can."

   "No," she said and the sensation to lick her ass vanished as quickly as
it had appeared.

   "Can I drink your pee?" my mouth asked, horrifying me.

   "Ew!  No!" she said and again the idea vanished from me.

   "Thank you," I croaked.  It took every bit of will I had to say those
words, too.

   "But I want to watch you pee," she said.

   As if she had flipped a switch, my cock immediately began spraying her
as the sudden need to evacuate my bladder overtook me.

   "What the fuck?  Stop!" she squealed, dancing out of the way of the big,
healthy stream of piss.  "Do it in the toilet!"

   I moved in front of the toilet, raised the seat, and released the rest
of my bladder's contents.  "Sorry," I sheepishly told her while I peed.

   "Dick," she said, blotting at her clothes with a towel.  Leaving me, she
went to her bedroom as I stood naked in the bathroom and wondered what had
just come over me.

   Remembering what she had said while we were in the basement, I moved to
the mirror and asked myself, "Can I get dressed now?" Without feeling an
objection to the idea, I went back downstairs and collected my clothes as
my head cleared a bit more.  I could remember everything I had done, every
second of it.  I could even remember why I had done it, how I felt like I
was doing it to prank Carol.  In the moment, every action I had taken had
felt logical and justified.  Was this how it had felt to her, too? 
Dressed, I sat on the couch and pondered what the fuck had just happened to
me.

   Dressed in clean clothes, Carol passed me on her way to the laundry room
with an armful of clothes.  "You should probably clean up the mess you made
in the bathroom."

   "Yeah," I said, pausing for a moment to see if I felt compelled to do
it. As near as I could tell, I didn't feel compelled to do it beyond the
acceptance that I had made a mess up there.  Stepping into the bathroom
felt like I had returned to the scene of the crime.  Snippets of pubic hair
were everywhere on the floor and counter.  The same with shaving cream and
her well-used razor.  At least my ass had been clean before I sucked my
finger.  I shivered thinking about how nasty all of that had been.

   When I was done, I found Carol sitting in the family room.  The TV was
on, but she wasn't looking at it.  Instead, she stared blankly into a
corner until she noticed me.  "Believe me now?"

   "I guess so," I admitted, unable to come up with a different explanation
for what had just happened to the two of us.  "So, what now?"

   "I don't know," she said in the most honest and genuine tone I had heard
from her in years.  "I can't believe I did what I did." With a tiny smile
on her face, she quickly added, "Or what you did.  Have you ever done any
of that before?"

   "What?!  No!" I emphatically assured her.

   "None of it, right?"

   "Right," I said, just as insistently.  "I have never shaved down there,
fingered myself, or . . .  you know, tasted myself."

   "Yeah, that part was pretty crazy," she giggled.

   I felt embarrassed and ashamed.  If I hadn't discovered her masturbating
the way she had been, it would have been worse.  "Did you know any of that
would happen?"

   She shook her head.  "I didn't think any of it would work."

   "Why do it?"

   "It's stupid." She shrugged before staring into the corner again with
that faraway expression on her face.  "I just get tired of being good all
the time."

   "Ha!" I snorted.  I had spent too many years being the victim of her
cruelty.  The rest of the world might see her as a goody-two-shoes, so prim
and proper, but I knew how bitchy she could be.  Carol was a chronic rule
follower who never drove a single mile over the speed limit for fear of
getting a ticket.  Back in high school, she always handed in her projects
early, studied before every test, and took details note in every class. 
She never went without a bra and never wore anything scandalous.  While all
her girlfriends had looked like high-class call-girls in their
tight-fitting, skimpy prom dresses for their senior prom, Carol's dress had
looked like something out of the Victorian era with its button up front and
long sleeves.

   "Don't be hateful," she corrected in her typical way.  "I know everyone
thinks I'm an uptight b-word."

   "Bitch," I said, filling in the word she didn't want to say.  While I
knew Carol could swear, it was rare for her to do it and some words were
always off limits around her.

   "Yeah," she allowed with a scowl since that was one of her off-limit
words.  "Don't you ever wish you could be really bad?"

   "Who says I'm not?"

   Carol rolled her eyes and snorted.  "Because you're not," she insisted.
"I've seen you in public.  Around here, you act like a moody gamer, but in
public, you're the sweet, nice guy everyone wants as their friend."

   "Fuck you," I growled, dismissing her accurate description of me as
forcefully as I could, except we were cut from the same cloth.  Just like
her, I couldn't leave the house unless I looked nice and I was wearing
clean underwear.  While I knew I had a dark side, it never showed.  If
someone offered me an alcoholic drink at a party, I would set it down
without drinking it because I still had two years before I turned
twenty-one.  I knew Carol was the same way because she had taught me that
trick.  Wait until they aren't looking and then set it down.  If they hand
you a bottle, block the opening with your tongue because it was better to
lie a little to your friends than it was to break the law.

   "How often do you jerk-off?" she asked.  Just hearing her say those
words startled me.

   "I'm not telling you that!"

   "Once a week?  Once a month?"

   "I don't know," I said, refusing to reveal such highly confidential
information.  It was none of her business how often I did that to myself.
"How often do you do it?"

   "Hardly ever," she said with a sweet smile even as she blushed a bit. 
"And, whenever I do, I feel so guilty afterward, like I just broke a
promise to my boyfriend or something."

   "You don't even have a boyfriend."

   "I know, but I still feel that way."

   "Why not?" I asked, wondering about why she didn't have a boyfriend. 
"Are you still a virgin?" The way she blushed told me she wasn't.

   "But I've never had an orgasm with a man," she said in a very quiet
voice.  "I mean, I want to, except I can't.  It doesn't matter how good it
feels, I can't do it.  It's like I can't let go or something."

   The idea of not being able to have an orgasm felt like such a girl
problem.  I couldn't imagine having that difficulty although I knew how
hard it was for me to get excited more than once or twice with my
girlfriends.  The first time was always the easiest because I would usually
get hard from all the kissing and making out before we got naked, but after
we did it, I always felt a little wrong for having sex.  Sometimes, I could
do it a second time, but that second time never felt as good as the first
time.  "Can you do it by yourself?"

   Carol gave a single, shy nod.  "That's the only time and it feels good,
but I know it should feel better with a guy."

   "What about earlier?" I asked without needing to describe when I meant
more than that.

   "Best orgasm ever," she said with a wistful smile.  "Like really good
and I don't even feel guilty about it.  Isn't that weird?"

   Thinking about how it had felt for me, I searched for the usual sense of
guilt I felt after getting off by myself and realized it wasn't there.  "I
remember feeling embarrassed that you were watching but also loving it that
you were there," I said, still working it out.  "And I can't believe I peed
on you."

   "Me either!" she giggled.  "But didn't it feel like I made you do it or
something?"

   "Yeah, it did," I realized.  "I mean, you said you wanted to see me do
it and just started doing it."

   "That's how I felt when you were asking me questions!  It was like I
couldn't lie to you."

   We mulled over our experiences, talking through them with a candor and
openness that felt as strange as the effects of the potion.  After what we
had witnessed each other doing, it made sense.  What else did we have to
hide?

   "Do you think it's a drug of some sort?" she asked.

   "I don't see how." I reflected on the ingredients.  None of them were
known for their hallucinogenic properties.  "Did you say something about a
spell, too?  Did you try it without doing the spell?" She shook her head
and I understood.  I'm not sure it would have occurred to me mix up a test
batch.  Like her, I would have followed all the instructions.

   "I didn't think it would work until it did." She smiled.  "How do you
feel?"

   "Normal," I said, doing a quick mental assessment.  "Actually, maybe
better than normal.  I feel good.  Clear-headed.  Nothing feels weird. 
What about you?" Her smile growing bigger and I could guess her thoughts.
"You first," I insisted.

   "We should try it again."

   "Together?" I asked, immediately discard the idea.  "What if something
crazy happens, one of us needs to be straight and sober.  But what if you
tried twice as much?  What would happen then?  Do you think you would go
crazy?"

   "Or maybe it just lasts twice as long?"

   "We should find out," I said, feeling like an intrepid explorer or a
scientist on the brink of an important discovery.  As we returned to the
basement, I looked again at the encircled pentagram on the floor.  "Mom and
Dad will freak out if they see this."

   "It's why I waited until they were gone, moron." Her insult didn't sting
in the least.  It had been a stupid comment since Mom and Dad were on a
ten-day cruise, that left plenty of time to clean it up.  Picking up the
flask holding the finished product, she swirled it before carefully sucking
on the end of the pipette.  Holding it up to the light, she released a bit
until only two drops remained.  She hesitated before putting it to her
mouth.  "Don't forget, I'll remember everything even if I can't help
myself. So, if you do anything funny to me, payback is a b-word."

   "Deal," I said, eager to find out what was going to happen.  The first
time, the effects seemed to have lasted about forty-five minutes for both
of us.  "Wait," I said, stopping her before she had released her finger on
the end of the pipette.  "Maybe I should go first this time."

   "Why?"

   Looking down at my feet, it took me a moment to admit the truth. 
"Because it was hot watching you and I'm worried what might happen.  It's
not like I can control it if I get excited."

   "But I really want to do it," she insisted.

   "I know, but what if instead of lasting twice as long, it's twice as
powerful?  Last time, you wanted to blow me."

   "And you didn't let me do it," she pointed out, opening her mouth and
releasing the liquid beneath her tongue.  "I trust you."

   "Fuck," I grumbled, unsure if I trusted myself.  "How do you feel?"

   "Fine," she said, eyeing me like a piece of meat.  "For the record, I
thought it was really hot watching you shave."

   "I did it because you told me to do it," I said, following her as she
left the unfinished part of the basement.

   "It was still really sexy seeing you do it," she said, still sounding
like Carol as we moved upstairs.  The stairs opened into the family room.
She paused at the top and began undressing.  She never turned around.  It
wasn't a striptease, either.  It looked much more methodical than that. 
Her voice sounded different when she said, "Get naked with me."

   "I don't think that's a good idea."

   "Sure it is," she said with that same faraway tone in her voice as if
she knew what she was saying, but couldn't stop herself from saying it. 
She tugged on my shirt.

   "Stop it," I said, stepping away.

   "You're no fun," she pouted, instantly releasing me.  Instead, she began
caressing her tits, pulling on her nipples and making them hard.  "Do you
think I'm sexy?"

   "Yes," I confessed, feeling awkward admitting it to her for a couple of
reasons.  First, because I knew there was a chance she would remember my
answer after the potion wore off and I would never hear the end of that. 
Secondly, when she asked that question, she had sounded like Carol again.
Had I not experienced the strange effects of the potion, I might have
believed she was playing me.  Except for being naked, she still looked like
Carol.  Nothing in her expression suggested that she felt out of control.

   "Get naked with me and I'll show how sexy I can be." That time, her
voice had that odd sound as if she wasn't really saying that.

   "Show me how sexy you can be without me getting naked," I replied,
already struggling with a rising sense of excitement.  She might be my
sister, but she was still pretty and naked and obviously horny.  I'm not
sure I would have had the same willpower if she hadn't been my sister.  I
ignored my rising lust.

   "Okay," she said, leaving her clothes behind and heading upstairs.

   Following her bare butt, I tried not to stare and couldn't help myself.
Seeing her all over tan had surprised me the first time I saw her naked and
then I remembered that her nail salon included a tanning bed.  "Does Mom
know you tan naked?"

   "Mom told me to do it," she said, sounding normal.  "She said it was
stupid to use a tanning bed and wear a bathing suit, too."

   "Does Mom know you shave your pussy, too?"

   "I waxed," she said with clipped syllables as if she didn't want to tell
me.  "A dare.  From Susan." Turning to face me, her voice changed back into
that other voice.  "Want to feel how smooth?" She tried pulling my hand to
her bare pussy.

   "No!" I said, pulling my hand away.  The truth was, I wanted to feel,
but I couldn't.  One of us had to be strong.

   "Mm, but it feels soooo good," she said, caressing herself for me.  "And
I'm so wet, too." She raised a glistening finger to her lips and licked it
clean before burying her finger inside her pussy and holding her hand there
as she walked towards her bedroom with its pink walls and frilly bed cover.
Shelves running about her bed displayed a mix of trophies won from a
variety of speech and debate tournaments.  Mixed between the trophies were
her favorite stuffed animals.

   Still holding her pussy, she pulled open her underwear drawer with her
left hand.  After fishing around beneath the tangle of cotton, silk, satin,
and lace, she surprised me by producing a lifelike dildo.

   "Oh my God, does Mom know you have that?"

   "No," she replied in her voice as a smile grew on her face.  "But you
wanted to see how sexy I can be." Sitting at her desk, she opened the lid
of her laptop and the dildo flopped as she typed in her password.  Being
very right-handed, she giggled when it took her two tries.  Looking over
her shoulder at me, she asked, "Are you sure you don't want to get naked
with me?  We can have a lot of fun."

   "I'm sure."

   "Please?" she asked, still talking in her Carol voice.  Oddly, it looked
and sounded like she was begging me to do it.  Shaking my head, I stood my
ground.  The funny smile that appeared on her face was unlike any smile I
had ever seen her wear before that moment.  Something about that smile
looked sinister.

   Pausing to lick her finger clean, she decided she needed her right hand
to work the mouse and I watched as she opened her web browser and typed
with both hands while holding the dildo in her mouth.  I watched as she
entered the address of an adult cam site.  She surprised me a second time
by logging into it with a username and password.

   "You've been here before?"

   She pulled the dildo out of her mouth long enough to say, "Just to
watch." Still holding the dildo, she clicked on the button in the corner
that read, "Broadcast yourself."

   I freaked out.  Even without knowing the site, I could guess what that
button did.  "What are you doing?  You don't have any idea who's on the
side?"

   "I know," she said, pushing back her chair, parting her legs for her
webcam and caressing between her legs with the dildo.  Even as she got
started, I saw a counter in the corner of her preview screen beginning to
advance.  It quickly increased from one to two, to dozens of people eagerly
clicking to watch her.  I couldn't blame them.  If I had been on the other
end of the internet and saw someone as attractive as her displaying
herself, I would have clicked on it, too.

   There was a chat window to the side of her preview window and I watched
as the comments began to flow.  Rude, crude and outrageous comments.  "Fuck
it, girl!" "Suck it!" "Fuck your ass!" One demand after another showed up
along with compliments.  "Hottest ever!" "100 Stars!" Snatching her mouse,
Carol deftly opened a second window.

   "This is why I really come here," she said, clicking the tab that
offered to show the cams of any guys online.  Within moments, she had
arranged different windows on her screen until she could see several guys
at once along with her preview window.

   "Have you done this before?"

   "Not broadcasted, but you said you wanted to see how sexy I can be." Her
voice sounded normal, not forced as she settled back to enjoy the show.

   "But what if someone we know is watching?"

   "I know," she said, flashing me that sinister grin below a look of
wide-eyed panic and I could tell it was the potion working its magic on
her. She was well aware of the risk and unable to prevent herself from
doing it just the same.

   "Stop it," I said, hoping my words would have some pull on her.

   "I can't," she groaned.  "Too hot."

   "Is that why?  Because you're too turned on?"

   She managed to shake her head.  "Because you wouldn't," she managed in
that clipped tone from earlier.

   "This is so wrong," I gasped, helpless to stop her as she stood, turned
and poked her ass towards the camera.  It took a second for me to realize
she was reacting to one of the comments in her window telling her to show
off her ass.  The words were small in that window, but one horndog had
typed in all caps so she could see it.  I saw what he said next.

   "FUCK THAT ASS!"

   As if she was nothing more than a puppet on a string, Carol pulled the
toy from her pussy and began trying to shove it in her ass.

   "Lube first," I said, genuinely afraid she was going to hurt herself. 
Her gaze darted in my direction, I saw the fear and panic in her eyes, but
her hands didn't stop trying to poke the toy in her butt.  Fuck, I thought
as it occurred to me that she couldn't help herself.  Glancing around her
room, I spied a bottle of lotion and grabbed it.  "Use this," I said,
reaching over and squirting it between her legs.

   "WHO IS THAT?" the person with cap lock in place asked.

   Typing with her bad hand, Carol still managed to reply, "my brother."

   With the addition of the lotion as a lubricant, Carol began experiencing
greater success with working her dildo inside her ass.  I heard her gasp as
it found purchase.  Furiously rubbing her clit, she had a huge orgasm
before she began coating herself with the extra lotion I had squirted
between her legs.  She rubbed her stomach, chest, and thighs until she was
glistening.  The entire time her eyes flickered across the screen and I
knew she had to stop noticing the comments from that prick with the caps
lock on.

   "Show me the cams you like best," I asked, taking control of her mouse
and pointing to each of the windows showing men doing stuff.

   "Yes," she gasped as the mouse passed over a cam showing two guys naked
guys sitting side-by-side.  Double-clicking brought the cam to fullscreen,
hiding the chat window while still showing her preview window.

   "Really?" I asked, startled by her choice of cams as the two young men
began stroking each other's pricks.  My sister liked gay porn?  She nodded,
still working over her body as she thrilled at the visual.  The two guys
looked close to my age.  Both were shaved and hard as hell.  Quite
unexpectedly, one of them flopped over and began sucking on his buddy's
hard cock.

   "Yes!" Carol cried out, experiencing another huge orgasm.

   "For real?"

   "Yes!" she insisted, licking her lips as she watched.

   "What else are you into?"

   After clicking the ESC button on her keyboard, she took the mouse away
from me and double clicked on a different cam.  In the new cam, another guy
around my age and build sat facing the camera with a dildo up his ass. 
Carol mimicked his positioning and rubbed her clit while watching him
stroking his cock.  It took me a second to realize she was also matching
his dildo strokes with her own stroking.  Once again, she shivered with an
orgasm from the thrill of it.

   "You like seeing him do that?"

   "He looks like you," she said, flashing me a big smile.

   I ignored her comment.  That felt too weird.  "Does that toy feel good
up your butt?"

   "Yes," she said in her voice.  I stared in her pretty blue eyes, trying
to find the lie inside her eyes and couldn't.  "Get naked," she insisted,
except I could hear the difference in her tone.  It might sound like her
voice, but it didn't sound like her vocal pattern.

   "Why?"

   "Suck you," she said with a smile.  Oddly, her voice sounded like a mix
between the strange tone and her normal voice.

   "Fuck?" she asked in that same mixed tone.

   "Later," I said, very aware of how turned on I felt.  Once it felt like
she was out of danger of hurting herself, my arousal had returned full
force.  Knowing people still watched her, I needed to get her away from the
computer.  "Come into the bathroom with me.  I want to watch you pee."

   Without a word, she stood and I shut the lid of her computer, ending the
show.  If we were lucky, no one we knew had caught her show.  I followed
her into the bathroom, confused when she straddled the toilet, facing
towards me.  Bending her knees, she splayed her pussy lips while holding
the toy up her butt with her other hand.  Looking down and giggling, she
released her flow, peeing from a mostly standing position.

   After the last drop, I suggested we go back downstairs, anywhere except
near her computer again.  I had no idea how much longer the potion would
keep hold of her.  Back in the family room, she crawled on the coffee
table, pointing her filled ass directly at me as she watched my reaction.
Suffering in silence, I sat with my legs crossed as my sister got herself
off again and again.  Each of her orgasms seemed as mind-blowing as the one
before it.  Part of me felt envious at her endurance, stamina, and ability
to keep getting off.  I kept the lump in my pants well hidden from her.

   Eventually, she seemed to regain control over herself.  Following one
more orgasm, she eased the toy from her butt and stared at it.  "Did that
feel good?" I asked.

   "Yes," she said in a faraway voice, but in a tone that belonged to her.

   "Does your ass hurt?"

   She shook her head, looking a bit puzzled.  She glanced at her clothes
near the basement door.

   "Would you like to get dressed?"

   "Shower," she said, managing a tiny smile.

   "That's a good idea," I said, sensing that the potion was at its very
end.  "Why don't go upstairs and shower?  I'll wait for you here." Looking
grateful, she nodded, walking past her discarded clothes on the way
upstairs.  While she was gone, it was everything I could do to stop myself
from jerking off in her absence.  I didn't risk it.  Besides, wasn't it my
turn to go next?

   With one towel wrapped around her head and another around her body,
Carol returned to reclaim her clothes.  She flashed me a sheepish smile
before stepping around the corner to get dressed.

   "Do you feel okay?"

   "You mean aside from feeling embarrassed as hell?" she asked.  "Other
than that, I feel good."

   "Sore?"

   "Not even a little," she said, stepping back into the family room.  She
eyed the coffee table as she walked past it, surely remembering what she
had done while kneeling on top of it.  She sat on the opposite end of the
couch again.  "Thank you for staying dressed."

   "It wasn't easy," I confessed.  We sat in awkward silence for a couple
minutes before I broke it.  "I didn't know you owned a sex toy." Carol
instantly blushed deeply.

   "It was a joke gift from Susan."

   I laughed.  "Susan is a bad influence on you."

   "Don't be mean," she said.  "Susan is just more open than me, that's
all."

   "Do you remember everything you did?"

   Her blush returning deep and dark, she nodded.  I asked about the
website she had visited and why she had an account.  "It times out if you
don't have one," she said.  "I can't believe I was on cam." I told her
about how she was following the instructions from that one guy.  "Oh, I
know!  I couldn't stop myself!  It was like, because you wouldn't do
anything, then those words became the best idea."

   "I was afraid you were going to hurt yourself."

   "That lotion costs thirty dollars a bottle."

   "Sorry," I apologized.

   "No, you're fine," she said with a quick, forgiving smile.  "Just wish
there had been something cheaper nearby." She shrugged away the expense. 
"You're a good little brother."

   "No, I'm not," I said, knowing how close I had come to taking advantage
of her.  We talked about the potion.  Apparently, twice as much meant it
had lasted twice as long instead of being twice as intense.  "What if you
had done a shot glass full of it?"

   "Oh my God," she gasped, revealing how close she had come to doing it.

   We did the quick math.  If one drop equaled .05 milliliters and lasted
roughly forty-five minutes, then a shot glass amount would last nearly a
month.

   "Would it really be a month of needing constant orgasms?"

   "I don't know," I said, unable to imagine how a person could function
like that.

   "Do you still want to take another turn?"

   "Yes," I said, immediately standing, which revealed the lump I still
sported.

   "Do you even need it?" she smirked.

   "Pervert," I said, already heading downstairs.  There were no two ways
about it, I definitely wanted my turn.  After enduring my sister's
lustfulness, I needed it.  As I filled the pipette, I considered the need I
felt.  "Do you think stuff is addictive?"

   "Maybe." Her eyes following the flask and then the filled pipette, as if
it was token held by a hypnotist.  As I tossed back my head and opened
mouth, she stopped me.  "Wait, any conditions before you try it?"

   "Just don't let me try to rape you." It was the same concern I had the
first time, too.

   As I released the pipette beneath my tongue, Carol asked, "What if you
want to jerk-off in your face again?"

   Deep in the back of mind, I felt an instant stab of regret for not
mentioning that.  Instead, I heard myself tell her, "It's all good."

   "Are you sure?"

   "Yeah, I'm horny as fuck," I said, already rubbing the front of my
pants. Damn, this shit worked fast!

   Smiling, Carol suggested we go upstairs so I could show her how horny I
was.  As I walked upstairs, I thought about how I felt.  Aside from feeling
remarkably horny, I felt in control of myself.  Well, except for how
eagerly I got naked as soon as I reached the top of the stairs, that felt
out of character.  Then again, was it really?  I was horny before I took
the potion.  Downing it meant I was free, didn't it?  Just like before, I
could say or do anything and later I could blame to potion.  I felt free.

   "Do you still want to touch?" I offered, waving my naked naughty bits at
her.

   Carol looked apprehensive as she eyed my hard cock and freshly shaved
balls.

   "Aw, come on," I chided, daring her to do it.  "Just because I didn't
touch you doesn't mean you can't touch me, does it?" I wondered how I
sounded to her.  Did I sound like me or did I sound slightly off like she
sometimes did?

   "You look so hard," she said, looking tempted.

   "And you can do anything you want to me," I assured her, desperately
hoping she would try touching me.

   "I want to see you get off, first."

   "Like before?" I asked as if jerking off again was the greatest idea I
had ever heard.

   "Sure," she giggled, looking delighted at my enthusiasm.  "Did you like
doing that?"

   "Yes," I said, feeling the answer flying out of me unforced and
unfiltered.  "I tasted good."

   "Show me how much you love it," she laughed as I got on the floor in
front of the couch.  Carol climbed on the couch, tucking her legs beneath
herself while I used the front of the couch to hold myself curled into a
ball with my dick pointed at my face.  Leaning over, she looked down at me
and asked, "Aren't you forgetting something?"

   Oh yeah, I thought, remembering how good my finger had felt up my ass.
Sucking on my finger, I got it good and wet before reaching around my thigh
and poking it deep inside my ass.  Damn, that really did feel good.

   "Maybe you should use two fingers," she suggested, smiling down at me.
What a good idea!  Pulling my hand back, I slobbered over my index and
middle fingers, not even caring where my one finger had been.  If anything,
knowing it had been up my butt made it feel sexier.

   I pushed two fingers inside my ass and moaned.  If one felt good, two
felt so much better!  It felt really good!  My cock twitched and throbbed
with its pent-up need from watching her.  Seeing her watching me made it
even better.  A clear droplet of precum appeared on my cockhead, oozing
from the slit of my dick until it built up enough presence to turn into a
real drop.  Opening my mouth, I caught it directly on my tongue as Carol
delightedly giggled.

   "Do it," she cooed.  "Make it cum a whole bunch like last time and eat
it all!"

   As if her words were my trigger, my mouth gaped open as my cock exploded
in my pumping hand and spurt after spurt of my creamy cum began pouring
from me.  My previous orgasm didn't seem to matter one bit.  Like before,
my orgasm felt porn-star big with one solid ejaculating pulse after another
pumping out my cream directly into my mouth.  As I came, I wiggled my
fingers inside my ass, coaxing my body to keep going.  In a strange way,
the arrival of orgasm felt much like when I had accidentally peed on my
sister as if her command was all it took to make it happen.

   "So hot," she groaned.  "I'm not even potioned-up and I'm hot as hell
watching this."

   "Do you want to touch me now?" I asked, remembering her earlier
condition.  "I came, just like you wanted."

   "In a bit," she said, filling me with frustration and disappointment.  I
ached for her caress and she all she did was smile at me.

   "Cunt," I said, trying desperately to hold back the abrasive word and
failing miserably.  "That's all you are, a stuck-up, good for nothing cunt.
It's no wonder you need a friend like Susan to buy you sex toys.  It's no
wonder your frigid with your boyfriend.  You don't know the joy of sex. 
Have you ever tasted a man's cum?"

   The abusive tirade poured me unabated.  I couldn't stop myself.  I saw
my sister recoil as if she had been slapped in the face.  Her smile
vanished as her mouth gaped open and her eyes went wide with shock.  When
her face turned red, I assumed she was blushing.  I couldn't be farther
from the truth.

   "Let's go upstairs," she growled with anger.  "Back to my bedroom.  We
can have some fun, I promise."

   I uncurled from my ass-up position against the couch, eager to follow
her.  "You should get naked with me."

   "Maybe I will," she teased, leading the way.  Following behind her, I
pulled on my still engorged prick, caressing that magnificent rod of
pleasure.  When I fondled my balls, they felt heavy and ladened with
another orgasm as if none had happened.  I stared directly at her wonderful
ass, fantasizing about seeing her naked again and all the things I could do
to her.

   Sitting at her desk, Carol reopened her computer, bringing it back to
life.  The multitude of windows she had opened were blank.  Standing very
near, I watched as she signed back into the webcam site.  I pushed as close
as I could until I felt the heat of her body against the tip of my prick.

   "Don't you dare touch me with that," she cautioned and it felt as if her
body heat had become an impregnable shield to me.  With her session
restored, she opened a couple windows of naked men.  In the first, a man
had his webcam focused directly at his hard prick, filling the view with
nothing more than his cock, balls, and his stroking hand.  "Does it excite
you to see that?"

   "Yes," I whimpered, trying hard to hold back the word, but unable to
keep it to myself.

   Carol's smile returned as she invited me to sit in her chair.  Leaning
close, she whispered in my ear and I felt her breath hot and wet against
the side of my face.  "I believe this potion works as some sort of truth
serum.  I think it releases our innermost desires and brings them forward,
even the things we're sure we could never do."

   Her words felt true to me, but meaningless at the same time.  I kept
staring at the large prick displayed on her screen.

   "Tell me what you would do to him if he was here in the room this very
moment."

   "Suck him," I confessed, feeling the thrill of my confession at the same
time that I felt the distant horror of saying it.  "I want his cum."

   "You love cum, don't you?" she asked, giggling.

   "I do," I whimpered, wishing I could hold back the words coming out of
my mouth.

   After clicking the "Broadcast Yourself" button, she handed me her dildo.
A small preview window opened in the corner where I could see myself
sitting naked and hard.  "Show me.  Show the world what you want to do."

   I began sucking on the latex representation of a man's cock.  I
slathered the smooth head with my tongue between bobs of my head as I
stared at the cock on screen.  Though the toy was fake, the sensation felt
real to me.  I couldn't distinguish between the toy and the cock I watched
onscreen.  My mouth felt filled with the flesh and blood of a real cock
swollen and straining for release.

   With my other hand, I stroked my cock.  I tugged and pulled on it as I
sucked on the not-quite-real cock in my mouth.  One sensation fed the
other. In a very strange way, I had the stranger's cock in my mouth along
with my own.  I felt as if I was sucking every cock I had ever seen and I
liked it.

   "Fuck, that's hot," Carol said, standing next to me and watching.  In
the preview window, I could see the panic in my eyes before I glanced at
her.  Even without the potion's help, she looked flushed and excited. 
"Suck it, bro.  Suck it good.  Make him cum in your mouth."

   I felt helpless to resist the sensations of joy inside of me.  Despite
never having a gay thought before that evening, my mind filled with the
possibilities of being with another man in the sickest, twisted, and
delightful ways.  I wanted this.  No, that's not how it felt.  I needed
this.

   "Can you cum again?" she asked.  I nodded, immediately feeling the need
within my balls.  "Cum on your toy and lick it clean.  Let the world see
how much you need it."

   I heard myself moaning as I lowered her fake cock between my legs. 
Taking careful aim, I allowed the joyful sensation of another orgasm to
overcome me.  Once more, I erupted with spurt after spurt of sperm filled
cum.  It splashed on the toy, coating it like mayonnaise on a Fourth of
July hot dog.  Carefully bringing it back to my mouth, I began licking
clean the toy.  I sucked on it.  I made sure to ingest every drop of my
orgasm and found myself wishing for more.

   "Now let him fuck you," she suggested, tapping the keyboard and bringing
a pair of men into view.  One man straddled the other, facing the webcam as
he impaled himself on his friend's massive cock.  The cock of the man
getting fucked was hard, too.  As I watched their union, I filled my
asshole with her slick toy.  When I needed more lubricant, I licked at it
and tried again until I had the toy buried deep inside my ass.  My cock
danced and throbbed in time with my thrusts.

   "No way," she gasped, laughing at me.  "Cum again for me.  Cum for all
of them."

   My eruption happened immediately.  I magically came in another round of
huge spurts that felt as good as my first orgasm.  In the back of my mind,
I knew it didn't make sense.  I shouldn't be able to do that.  Repeatedly
cumming that hard defied the workings of my body as I understood it.  But
the proof rolled down my chest and stomach.  I had cum again and loved
every second of it.

   "Clean yourself up," she said and I did so without removing the toy from
ass.  Feeling filled felt too good.  Instead, I scooped up one rivulet
after another and fed it to myself.  Closing her laptop, Carol leaned close
to say one more thing.  "Now the whole world knows you love cock."

   Rather than complain about what she had said, I smiled at her.  "Will
you touch me now?  You know you want to."

   Glancing down at my swollen cock and balls, I watched Carol consider the
proposition.  I could tell she was curious how my shaved parts might feel.

   Instead of touching me, she asked, "Are you done with my toy yet?"

   "Almost," I said, starting to feel the effects of the potion wearing
off. The toy still felt good, but not quite as good as before.  After I
slowly eased it from ass, she suggested we go back downstairs.  I stood up
and led the way.

   Back in the family room, I sat slouched on the couch and watched as I
caressed my hard cock.  It did look good shaved and touching it felt good.
However, I became increasingly aware of my sister sitting on the far end of
the couch and how she was watching me.  The longer I sat there, the more
awkward that began to feel.

   "Why don't you get dressed?" she asked and that felt like a very good
idea.  Picking up my clothes, I stood to the side of the opening to the
family room and got dressed.  The potion had worn off and I was left with a
hard-on, a pleasant feeling deep inside of me, and the shameful memory of
everything that had just happened.

   "Welcome back," she said with a gleeful smirk.  "Did you have fun?"

   Struggling to find an ounce of anger, I found I couldn't.  Was the
potion still wearing off?  "I can't believe you did that to me."

   "Did what?" she asked if she was as innocent as an angel.

   "Put me on cam," I said, still unable to feel outraged.  I did feel
ashamed and embarrassed, but not angry.

   "You said I could do anything except let you rape me."

   "I guess so," I mumbled.  "But you went too far."

   "Really?  After what you said to me, you really think I went too far?"

   "That wasn't me," I said.  "I don't really feel that way.  I was just so
pissed off that you wouldn't touch me."

   "I know," she said, leaning over and touching my arm.  "I could tell
because you sounded different.  Not completely different, but different
enough."

   "That happens to you, too," I said, describing how her voice was the
same, but different, too.  She nodded the entire time.

   Sitting on opposite ends of the couch, we analyzed everything that had
happened.  She wanted to know if I felt like I had latent gay tendencies. I
told her I thought it had more to do with seeing her watching cams.

   "I think I wanted to get you excited." That explanation made better
sense to me than imaging that I was secretly gay.  There was another part
of the experience that really bothered.  "I can't believe how much I came.
I mean, every orgasm felt as strong and powerful as the first one." She
looked confused and I explained to her how guys needed recuperation time
between orgasms, especially to rebuilt their spunk.  While I didn't quite
understand the physiology behind it, I knew it was true.

   "Maybe it's magic," she suggested and I laughed long and hard.  No, I
take that back.  I laughed until I remembered the pentagram drawn on the
floor of our basement, the black candles, and how she had said it all
required reciting a spell, too.  Smiling patiently, as if I was the slowest
student in the class, she asked another question I couldn't explain. 
"How's your butt feel?"

   "Fine," I said, immediately realizing that I should be sore.

   "Mine, too," she said.

   "How do you think it would feel if we didn't use the potion?"

   "Try it and find out," she joked.  I shook my head.  That would be a
mystery for another day.  "What about feeling tired?"

   "I'm more hungry than tired," I realized even though it was nearing
midnight.

   "Me too," she said, heading into the kitchen where the two of us took
turns heating up food in the microwave.  By that time, it was after
midnight and bed sounded like the reasonable suggestion.  Following her
upstairs, I admired her ass without fantasizing about it

   "Good night, Carol," I said from the top of the stairs before turning
towards my room.

   "Night, bro," she said and for a brief moment, I thought we were either
going to hug or kiss.  Instead, she turned and headed to her room, too.

   Sleep eluded me for hours as I laid in bed and tried to make sense of
the evening.  My mind flickered from one improbable event to another,
starting with how I had found my sister naked and masturbating to the
number and copious volume of my orgasms.  None of it made sense unless I
allowed for the possibility of magic.

   My cock swelled and throbbed until I couldn't stand it anymore. 
Climbing out of bed, I stripped down and began pleasuring myself to
memories of my sister naked and fingering herself.  Touching the smooth
flesh around my cock felt naughty and good.  It took a while before I
reached my climax.  Cupping a hand in front of my prick, I spewed my seed
into my palm.  The orgasm felt good but not as good as when I was on the
potion.  My orgasm came out as little more than a dribble as if my body had
nothing more to offer.  On a whim, I licked my palm clean.  My cum still
tasted the same.  I refused to acknowledge if I thought it tasted good or
bad.

   That familiar sense of vague guilt crept over me as if I had somehow
cheated by masturbating.  I knew that feeling and brushed it aside. 
Feeling normal felt good and a bit disappointing.  Back in bed, I curled up
and eventually found sleep.

   In the morning, I felt good despite my limited sleep.  Being shaved bare
still felt strange.  Unable to take all my classes online, I had to venture
out into the world.  While I ate cereal in the kitchen, Carol came
downstairs dressed for work.  We gave each other sheepish smiles.  "How do
you feel?"

   "Good," she reported.  "In fact, remarkably good.  You?" I assured her I
felt the same way.  To my eyes, she looked better than good, she looked
radiant.  It felt funny seeing her as a woman, as attractive as any woman I
knew.  I considered telling her about jerking off last night and how it had
felt normal.  Instead, I kept it to myself.

   After my last class, I drove straight home.  When I opened the door to
the unfinished section of the basement, I was greeted by the pentagram
encircled twice.  Seeing the arcane symbol felt strange.  I didn't feel
filled with dread, more with the fear of the unknown.  I gave the diagram a
wide berth.  I wanted to explore the ingredients, trying to apply logic and
reason to the inexplicable events of yesterday.

   None of it made sense.  How could combining these simple ingredients
have such a profound effect on libido and physiology?  I made a list of
them and headed to my room for more research.  I found a number of sites
devoted to the black arts and magic spelled with as "magick" as if that
changed the word.  I couldn't go there.  Believing in magic held
implications I couldn't consider.  Instead, I choose to believe Carol has
somehow stumbled upon an herbal version of Viagra.

   With the house to myself, I realized I had the opportunity to conduct
another experiment.  Stripping naked, I surfed to one of my favorite porn
sites and began stroking myself.  I'm a lotion sort of guy and kept a
bottle of unscented lotion hidden in my room for just such an occasion.  As
I worked the lotion across my smooth flesh, my body welcomed the attention
as much as my libido did.  Being hard felt as good as ever.

   Reaching beneath my balls, I ran a slippery finger across my butt and
shivered with unexpected pleasure.  I wasn't expecting that.  I had never
considered my ass an erogenous zone, but I guess I had been wrong.  I
experimented with inserting the tip of my finger inside that tight,
puckered opening and discovered that felt good, too.  Really good. 
Recalling yesterday, I experimented with a second finger.  That felt more
filling.  Before I knew it, I sprayed my stomach with my orgasm.

   Looking down, I noted the amount of my cumshot.  It looked normal. 
Except for the two fingers I had pushed inside my butt, everything about my
orgasm felt normal.  Wiping lotion off my finger, I tried tasting my orgasm
again.  It tasted vaguely salty.  Perhaps more revealing, I realized it
tasted the same as it had when I orgasmed directly into my mouth.  I made
mental notes about the experience as I cleaned up.

   Checking the time, I saw that I still had over an hour before Carol
returned from work.  I considered the flask of potion two flights of stairs
away.  Should I risk trying it alone?  There hadn't been any ill effects
from using it.  I had the time, especially if I limited myself to a single
drop.  Throwing caution to the wind, I decided to give a try.

   Oddly, nothing happened.  I even tried to jumpstart its effect by
returning to my room and getting naked again.  I got hard and that felt
good, but I didn't feel that same urgency as before.  I tried jerking off,
but plateaued somewhere before my climax.

   Shortly after discovering the joys of masturbation, there had been a day
when I had decided to see how many times I could get off.  Hidden in my
room, I had jerked off over and over again.  The first three orgasms had
happened relatively quickly.  On my fourth try, it had taken a long time to
push myself over the edge.  On the fifth try, I never did it.  I had gotten
excited, hard, and close to an orgasm, but had never quite managed to find
the extra thrill required to push me over the edge.

   That's how I felt, excited, hard, but an orgasm felt out of reach.  That
didn't make sense.  Had the potion stopped working?  Did it only work on
the day it was created?  Did I need more of it?  Remembering the math of
how long it lasted, I dismissed the idea of taking a second dose.  After an
hour had passed, I gave up trying.  I probably could give myself an orgasm,
but it would be forced and I didn't want that.

   When Carol came home, I told her about my experiments, starting with
jerking off last night.  Admitting that I had masturbated felt embarrassing
as hell.  Carol did her best at keeping herself in check, but wouldn't stop
grinning.  "What?" I demanded.

   "It's just funny hearing my brother telling me that he played with
himself."

   "Do you want to hear about this or not?" She nodded and only giggled a
little as I described the reduced emission from last night's final orgasm.
I left off tasting it, that was none of her business.  When I told her
about that afternoon, I left out the part about fingering my ass, too. 
Despite yesterday's events, admitting any of it to my sister felt too
embarrassing.  Finally, I reached the part where I had tried self-dosing
and its lack of effect.

   "Are you crazy?" she asked, chiding me for doing something ask risky as
taking it alone.  "What if something bad had happened?"

   "That's just it, nothing happened at all," I insisted.  Her point wasn't
lost on me, except I couldn't change what had already happened.  She made
me promise not to do it again before we could talk about anything else,
including the lack of any effect on me.  "Do you think it has an expiration
date?  Maybe it's only good for a single day."

   "Maybe," she allowed, thinking it over before coming to the obvious
conclusion.  "I guess there's only one way to find out, right?" I followed
her downstairs and watched as she carefully mixed the elixir with the
pipette before filling it.  Before releasing her dose, she made me promise
I wouldn't let her broadcast herself on that cam site.  She released her
finger on the end of the pipette and we waited to see what would happen.

   "How do you feel?"

   Carol shrugged.  "The same as always."

   "Do you want to get naked?"

   She shrugged again.  "Not especially.  I mean, I like being naked.  It
feels sexy being naked, but it's not like yesterday when I felt like I
needed to be naked."

   "Maybe it needs more time to work?" I asked.  We went upstairs to the
family room.  Yesterday, that was as far as we had to go before it had
clearly kicked in.  I waited for her to do something and nothing happened.
"Still don't want to get naked?"

   "Not like yesterday.  It's like I said, it's fun being naked, but I
don't feel a need to do it."

   "What about play with yourself?"

   Carol smiled.  "I've wanted to play with myself all day.  I did it last
night, too, like you did, and it felt good."

   "But what about right now?"

   "Sort of?" she said as if asking herself.  "I mean, I feel really horny,
but like I said, I felt horny all day.  I kept thinking about you and
seeing you naked again.  I like seeing you naked.  I like being naked in
front of you and I really liked watching you jerk-off." Smiling, she
squirmed a little and I wondered if the potion was beginning to take
effect.

   "What else?"

   "I just like you," she said with a faint blush pinking her cheeks.  "I
think you're sexy.  It's why I have to be mean to you so you don't know how
much I like you.  Did you notice all those guys I picked out yesterday? 
Did you notice how they were all built like you?"

   "Interesting," I said, referring more to how open she was being.  "Tell
me more."

   "It's why I wanted you to finger your ass and cum in your mouth because
that's what they do."

   "Wait, because that's what they do or because they remind me you of me?"

   "Both," she said with a big smile.  She tucked her heels beneath her
butt, getting comfortable and I saw the sparkle in her eye.  She leaned
towards me, touching my hand.  "They remind me of you.  You remind me of
them.  So why wouldn't I want to see you do the same stuff they do?"

   Her logic made sense.  More importantly, I detected the effect of the
potion.  While she didn't feel the uncontrollable desire to get naked, the
truth serum part still worked.  What about the suggestion part?  What if I
told her something to do, would she do it?  "Stand up," I said.

   "Sure," she said, untangling her legs and standing.  "What's up?"

   "Turn around and let me see your ass."

   "Um, okay," she said, turning to show me her backside.  She looked at me
over her shoulder.  "See something you like?"

   "Maybe," I said, unsure if she was following my directions because of
the potion or just because.  I needed to be more direct.  "Get naked."

   "Why?"

   "Because I want to see you naked."

   "And then what?  Are you going to get naked with me?" She sat back down
and smiled at me.  "I'll do it if you do it."

   "But you don't feel like doing it just because of the potion?"

   She shrugged.  "Maybe a little, but I don't feel like I have to do it,
does that make sense?"

   I nodded, racking my brain for something outrageous to ask.  "Do you
want to fuck me?"

   "Yes," she blurted out, immediately covering her mouth with both hands
and giving me a panicked look.

   "Did you want to tell me that?" She vigorously shook her side-to-side.
"But you really do want to fuck me, don't you?" With the same wide-eyed
expression of panic in her eyes, she nodded just as vigorously.  I peppered
her with more embarrassing questions.  "Are you wet?" She was.  "Are your
nipples hard?" They were.  "Did you think about me when you masturbated
last night?" She had.  "Did you finger your butt last night?"

   "I'm not answering that," she said even as her head bobbed up and down.

   "Did you use your toy again?"

   "No," she said without the head bob.  Either the potion was wearing off
or she was telling the truth.

   "If I got naked right now, would you suck me off?"

   "Are you going to potion-up first?"

   I glanced at the clock and saw forty-five minutes had passed.  "I think
the potion has worn off."

   Considering that for a moment, Carol smiled before saying, "I didn't
mean any of those things I said."

   "Wait, that's unfair!" I complained, remembering how the potion had made
me feel like I had a ready excuse for doing and saying stuff I would never
do under normal circumstances.  Either her answers had been lies or the
comment she had just made was a lie and I couldn't tell the difference.

   "Guess it's your turn so I can ask the questions," she said with a sly
smile.  She was right, too.  If I was willing to take another dose, then I
would know if first hand if I could lie under its influence.

   "Fine," I said, leading the way downstairs.

   Carol didn't start the questions until we had returned to the couch in
the family room.  "Do you want to show me your dick?"

   "Yes," I answered, learning nothing.  Wanting to do it and being willing
to do it were two different things.

   "Then go for it.  Let me see it." Though I felt sorely tempted by her
invitation, I found it easy to resist that temptation.  She looked
disappointed and that made me smile.  It felt good being in control.  "Did
you like eating your cum?"

   My single word answer flew uncontrollably out of my mouth.  "Yes." I
heard myself saying it.  I felt myself admitting it.  I also felt
embarrassed admitting it.

   "Would you ever do it for real?"

   "Do what?" The question felt too ambiguous to answer.

   "Suck off another guy for me."

   "Yes," I said, blushing deeper.  "I would do anything for you."

   "Then get naked."

   "No," I said, remaining in control of that part of myself.

   "Are you hard?" she asked.  I nodded.  "Show it to me." Though tempted,
I didn't.  Again, she looked disappointed.  Her disappointment didn't last.
A sly smile appeared on her face before she asked, "Do you love me?"

   "Yes," I confessed.

   "But you never tell me that."

   "You're my sister.  I have to love you."

   "Do you want to make love to me?"

   "Yes," I said, frustrated that I couldn't withhold that single word.

   "Did you ever check me out before seeing me naked?"

   I managed to reduce my answer to only a nod, but that was still an
answer.  When she asked me to explain, I had to use words as I told her
about getting excited at seeing her in a bikini.  Blushing madly, I
confessed to jerking off while thinking of her tight ass and perfectly
shaped tits.

   "Do you really think my tits are perfect?"

   After I nodded, she asked why and I explained how I thought her tits
were the perfect combination being a handful without being too big and how
much I liked her nipples.  Unable to stop myself, I added that I wished she
wouldn't wear a bra so often because I really liked seeing her nipples
poking through the fabric of her shirt.

   Reaching behind herself, Carol undid her bra.  Doing nothing more than
fishing beneath her t-shirt, she worked one strap off her left arm before
pulling her bra out of her right sleeve.  It looked like an amazing magic
trick.  After smoothing down her shirt, I saw her nipples stiff and hard
against the thin fabric of her shirt.

   "Does this make you want to get naked?" I nodded.  "Then do it," she
told me and I resisted.  As much as I wanted to do it, I didn't feel
compelled to do it.  I did ask if I could see them and she just laughed at
me.  "Get naked and I'll get naked."

   "See?  That's really tempting," I said, recognizing that she was testing
the potion.

   "If I brought a boy home and wanted you to suck his cock for me, would
you do it?"

   "Maybe," I said.  "Depends on who it was and how excited I was."

   "But you wouldn't be mad at me for making you do it, would you?"

   "No," I said, marveling at my candid reply.

   "If it got me really excited, would you let him fuck you, too?"

   "Maybe," I said, excited by the idea.  Seeing her squirm made me feel
even more excited at the idea.

   "What if we each brought a friend over and gave them the potion?"

   "My friends wouldn't need the potion to fuck you.  They all think you
are hot."

   "I don't want to fuck your friends," she said.

   "Do you want to fuck me?" I asked.

   She only smiled.  Instead of answering, she turned the question around.
"Do you want to fuck me?"

   "Yes," I said.

   "Get naked and I'll let you."

   I stared at her for a long moment.  I could feel the pull of risking
nudity for such a great reward while sensing a trap.  "You get naked
first," I said.

   "I thought I had you," she said with a big smile before spending the
final fifteen minutes peppering me with lots of questions and not all of
them were about sex stuff.  She asked if I had ever cheated on a
girlfriend, if I had ever been in love, and if I had ever cheated on a
test. She received a series of negative answers.

   The effects of the potion faded exactly on time and I found myself able
to lie to her again.  None of the lies were about important things.  I even
admitted to lying so she would know the potion had worn off.

   "Is it wrong that I was hoping it worked on you?" she asked.

   "I am hard, if that matters," I said, even letting her see the lump in
my shorts.

   "I'm horny, too, but it's not the same, is it?"

   I agreed.  While it felt good admitting my arousal to my sister, the
idea of acting on it felt like a step too far.  "I wish we had done
something last night."

   "Like had sex with each other?" she asked.

   "Maybe," I hedged.  "What about you?"

   "Let's eat," she suggested and I wasn't sure how to interpret that. 
That wasn't a hard "no." Did that mean part of her wished the same thing?

   Together, we raided the freezer for crappy comfort food.  She ate a
couple pizza rolls while I scarfed down a couple White Castle sliders.

   "I could try mixing a new batch," she suggested.

   "Or maybe you just need to say the spell again?"

   Back in the basement after dinner, we explored her remaining supplies
and vetoed the idea of mixing a new batch when she pointed out how little
she had left of some of the key ingredients.  "If we use them tonight, I'm
not sure I can get more."

   "Let's try the spell a second time and see if that restores what you
already have."

   We agreed that was a good place to start.  After lighting the candles
again, she shooed me out of the room.  When I asked why she said it was
because she had to get naked to cast the spell.  I pointed out that I had
already seen her naked, but it didn't matter.  Knowing that if it worked, I
would see her naked anyway, I agreed to wait in the Party Room.

   Less than fifteen minutes later, she opened the door and I saw she was
dressed again.  "I guess you didn't take any yet?"

   "I did," she admitted, smoothing down her shirt.  "But I still felt
funny about being naked." That answered the question about whether reciting
the spell was enough to recharge it or not.  "I think you should take some,
too."

   "Really?" I asked, wondering what the point would be.  What would be
magical about both of us being truth tellers for another forty-five
minutes?

   "Just do it, okay?" she pleaded.

   "Sure," I said, stepping around the drawing on the floor and filling the
pipette.  When she told me she had taken a double batch, I did the same.

   "Anything?" she asked.

   "Not that I can tell," I said, feeling normal.  I tried to think of a
good question to ask her.  "Do you want to get naked?"

   "Yes," she said, although she blushed, too.  "What about you?"

   "I do, but I don't think it's because of the potion."

   "Same here," she said with a cute, shy smile.  She darted upstairs and I
followed.  I found her on the couch staring at me with a big smile on her
face.

   "Are you thinking what I'm thinking?"

   In a small, tentative voice, she revealed that she was.  "That maybe we
should get naked and see what happens?"

   I nodded.  "I mean, we've already seen each other naked, right?"

   Nervously biting her bottom lip, she nodded.  "Do want to see me naked
again?"

   "Yes," I said, giving an answer that didn't require the effects of the
potion.  "What about you?  Do you want to see me naked again, too?" Wearing
that same shy smile, she gave me a curt nod.  I took off my shirt and
paused, waiting for her to do it without me asking.  A moment later, she
pulled off her t-shirt and my eyes moved directly to her bare breasts and
her stiff nipples.  Hooking my thumbs into the waistband of my shorts and
underwear, I whisked them both off at the same time.  Giggling, Carol did
the same thing.

   "This feels so wrong, doesn't it?"

   "Yeah it does," I admitted, very aware that I didn't need the potion to
reach that conclusion.  "But good, too." I rubbed my cock, felt
self-conscious about it, and stopped.

   "I like seeing you do that," she said, still staring at me as I sat on
the couch.

   "You mean this?" I asked, caressing myself again.

   "Yes," she cooed, sliding a bit closer for a better look.

   "You do it, too," I said in a hoarse sounding voice.

   "Touch you or me?"

   "Me," I said, not realizing that had been an option until she had asked.
"I mean if you want to."

   "I am curious," she said, putting her hand on my knee.  Her touch felt
electric and my cock throbbed.  "Are you making that happen?"

   "It sort of does it on its own."

   She slid her hand a bit farther up my thigh and it happened again.  She
giggled.  "You have such a pretty penis."

   That made me laugh.  "Cock," I corrected.  "It's called a cock.  I have
a cock and you have a pussy."

   "Cock," she giggled as if saying the word for the first time.

   "Your brother's cock," I pointed out as her hand moved still farther up
my thigh.

   "Oh God," Carol said, jumping a little.  "That made me tingle!"

   "Made your pussy tingle," I said, feeling my cock throbbing again.

   "My cunt," she said, instantly turning a deep, bright red and laughing
like a crazed woman.

   "Have you ever said that word before?" I asked.  She shook her head. 
"Say 'bitch,' another of her taboo words.

   "Bitch," she recited, over-enunciating every sound to the word.  She
squirmed again after saying it.  "Ooo, it feels good talking dirty!"

   "Did you say it because you felt like you had to say it?"

   She shook her head.  "I said it because I wanted to say it." Moving her
hand the rest of the way up my thigh, she grabbed my cock.  "And I'm doing
this for the same reason."

   "Oh my God," I groaned, amazed with how good her hand felt.  I felt my
heart pounding against my chest and my balls felt like they might burst
from a single touch.  "I can't believe you're doing that."

   "Me either," she said, staring at her hand as she caressed the
smoothness around my cock and fondled my hairless balls.  "This feels
really good all smooth."

   "Can I touch you?" I asked, staring at her heaving breasts.  She nodded
and I cupped her firm, supple breasts, raking my hand across her perfectly
shaped swells and admiring the way her stiff nipples raked against my open
palm.  "I want these," I blurted out.

   "They want you," she said, guiding my head to her chest.  Arching her
back, she fed me one excited nipple and then the other.  I slathered both
of them with my tongue, delighting in their perfection.

   "This is getting me too excited," I said, pulling away and looking at
her wet nipples glistening from my tongue.  I fingered one of them,
remembering how she had tugged, pulled, and slightly twisted on it.  I did
that and smiled when she squirmed.

   "Can I try to make you cum?" she asked, sliding her hand up and down my
cock.

   "Yes," I gasped, already feeling the sensation welling up in my balls to
a fevered pitch.

   "I can't believe I'm doing this to my brother," she cooed, working me
harder and faster, apparently learning a thing or two from watching guys
jerking off online.

   "Say that again," I groaned.

   "My brother?" she asked, sensing the impact that had on me.  "My
brother's cock feels soooo good."

   That was the extra encouragement I needed to explode.  Seeing her naked
again and having her touch me was too much.  Add to that her words and
there was no way for me to resist the thrill of an explosive orgasm. 
Gasping, groaning, and moaning, I shot my creamy load in big arcs that
reached all the way to my chest.  Laughing like she did on a roller
coaster, Carol kept pulling and jerking until the final spasm leaked one
last spurt along her fingers.

   "Care to taste it?" she asked, putting her cum-coated fingers against my
mouth.  Without hesitation, I licked and sucked at her fingers as she
gleefully giggled.  "Here, have some more!" she said, scooping it off my
body and feeding it to me.

   "You like this, don't you?" I asked between her finger feedings.  "You
like seeing your brother eat cum."

   "Yes," she gasped, squirming as if she was sitting on a row of tacks.

   "Can I touch you, too?" I asked, my hand already on her knee.

   "God yes," she said, pulling my hand up to her pussy.

   I barely noticed the smoothness of her waxed pussy as my fingers dipped
between her lips to feel the warm wetness inside.  My fingers zeroed in on
her clit, marveling at how easy it was to find hers.  As soon as I began
caressing her clit, Carol came with huge groans while grinding against my
hand.  At first, I was afraid she would going to pass out from the strength
of her orgasm as her breathing hitched for a long moment.

   "That's the first time someone else has made me have an orgasm," she
sighed, looking at me with stars in her eyes.

   "Can I try again?"

   "Yes!" she said, slouching down on the couch, parting her legs and
giving my hand full access to pussy.  I leaned over and sucked on her
nipples as I played with her pussy.  At one point, I filled her pussy with
two fingers and she squirmed.

   "Careful or I'll want something more." I felt her hand tugging on my
cock and felt a thrill as I realized that's what she meant.  For the
moment, I kept doing what I was doing since I sensed she was close to
another orgasm.  A few seconds later, I discovered I was right.

   Carol went limp on the couch, panting to catch her breath.  Her face and
chest were flushed from the thrill of her orgasm and she looked so
beautiful to me.  That's my only explanation for what I did next.  Without
asking, I leaned over and kissed her lips.  As soon as our mouths touched,
she clamped a hand on the back of my head and insisted on kissing me back.
As our tongues met, there was no mistaking this as the sort of kiss shared
between a brother and sister.  I was actually the one who broke our kiss by
pulling away.

   "Too much?" she asked, looking worried.

   "No, not enough," I said, kissing her again as our hands freely roamed
each other's naked bodies.  It didn't seem to matter where she touched me
because every caress felt as divine as her lithe, supple body felt to my
roaming hands.  I felt a passion I had never known and in the back of mind,
I became increasingly aware that it was because she was my sister.  Pulling
away again, I asked her, "Do you think this feels even better because I'm
your brother?"

   "Yes," she admitted.  "But I don't care."

   "Me neither," I said, going back to kissing her until she tapped out.

   "You're still so hard."

   "Because of you," I said, enjoying the touch of her hand on my cock.

   "Are you sure?"

   Glancing over my shoulder at the clock, I gave her the best answer I
could.  "Ask me again in twenty minutes."

   "I want to suck your cock before then," she demanded, slipping to the
floor and between my legs.

   Looking down at her, I smiled because I knew how she felt.  If we were
only able to do this because of the effect of the potion, she wanted to get
as much in as she could before it felt strange and awkward.  "And my ass,"
I urged her, going all in.  If this was because of the potion, I wanted to
try it all.  "Finger my ass."

   "Such a naughty brother," she grinned before sucking on two fingers. 
Right after she replaced those two fingers in her mouth with my cock, I
felt her slippery fingers pressing against my asshole and I welcomed them.

   "Deeper," I groaned, meaning her fingers, but she seemed to think I
meant both.  I watched as she forced my cock farther inside her mouth.  If
I had pubic hair, her nose would have been buried in it.  Meanwhile, I felt
the fingers in my ass going as deeply as she could reach and it felt good,
really good.  "Do it, Carol," I said, thrilling at the intense combination
of sensations.  "Suck me.  Suck your brother's cock.  Fuck my ass.  Fuck it
good!" I saw her ass wiggling as she sucked and fucked me and I could guess
that she was dire need, too.

   "I'm going to cum!" I warned her.  "I'm going to cum in your mouth!"
Carol never moved away.  Instead, she redoubled her efforts, pounding my
ass with her probing fingers, and getting me off as strongly as ever as I
exploded inside her mouth.  "Fuck, that felt good."

   Carol smiled up at me.  "So you're saying your sister is a good
cocksucker?"

   "Stop it or you'll have to do it again," I laughed, surprised by her
crude choice of words.

   "I will," she said, sucking me again.

   "No, it's my turn," I said, pulling her over me.  After we kissed again,
I rolled on top of her before sliding to the floor.  I put my hands beneath
her knees and forced them up to her chest.  "I wanted to do this
yesterday," I said, burying my tongue against her asshole.  I couldn't
guess why or where I had developed the craving to do something like that.
It felt as weird as getting off on the idea of sucking dick, but as I did
it, the answer came to me.  What could possibly be more wrong and intimate
than this?

   "Yes!" Carol cried out, squirming against me.  "Eat my ass!  Eat it!" I
did for a bit longer before moving to taste her sweet, smooth pussy. 
Without her asking, a put a finger in her ass as I ate her cunt.  She
whimpered, squirmed, and came repeatedly from my tongue lashing and I
didn't stop until she went limp.

   Weak from her orgasms, she still urged me on top of her.  Resting on top
of her, we kissed over and over against.  That she could taste herself from
my tongue, lips, and cheeks didn't dissuade her in the least for welcoming
my kisses.  As I rested on top of her nude body, I felt the effect of her
flesh so close to mine and the impact it had on me.  Cradling her face, I
stared deeply into her eyes and felt my heart fill with affection for her
that I couldn't withhold.  Stroking her cheek, I smiled and said, "I love
you."

   "I love you," she replied, kissing me again before reaching between us.
Her tiny hand grabbed my swollen cock.  "Now prove how much you love me." I
felt her placing my cock against her pussy.

   "Carol, we can't," I said, rolling off of her with a start.  "How do we
know this isn't the potion?"

   "I don't care," she said, crawling on top of me.  She sat on my thighs
and pulled on my hard cock while looking down at me.  "What if it's not?"

   "Say the C-word again," I requested as a test.

   "Cunt?" she asked, giggling a bit.  "Or cock?" She giggled again.  "Or
maybe you want me to ask for your cock in my cunt, is that better?"

   "You're brother's cock inside his sister's cunt, right?" I asked,
laughing with her.  It did sound funny being that explicit, but it also
felt like the potion's effect.  Looking past her, I glanced at the clock
and saw we were well past the time limit of the potion.

   Carol followed my gaze, immediately guess where I was looking at why. 
"Hm, it's past time and I still want your cock in my pussy."

   "And I still want to fuck you," I said, guiding her forward on my legs
and inviting her to take me for a ride.  Moving with me, Carol held my
swollen cock and guided me deep inside her warm, wet pussy.

   "You realize the potion had probably worn off before you said you loved
me."

   "Shut up and fuck me," I said with my hands on her hips gently urging
her to move up and down.  As she did, my hands slipped to her perfect
breasts and I felt the joy of fucking filling me with lust.  "Damn, your
pussy feels good."

   "Mm, your cock feels better," she moaned.  "My brother's cock," she
added and her eyes fluttered as a wave of pleasure surged through her.  I
felt that pleasure between her legs as a series of contractions around my
cock.

   "That's getting you off, isn't it?" I asked with a smile.  "You like
that you're fucking your brother, don't you?"

   "Yes," she gasped as her pussy clenched around me again.

   "And what if your brother cums inside of you?  Can I do that?"

   "Yes!" she cried out, squirming hard against me.  "Cum for me.  Cum
inside your sister!"

   Feeling like those were trigger words, I couldn't hold back.  Holding
her hips, I pressed her against my cock as I thrust upwards, filling her
pussy with my cock and my seed at the same time.  In counterpoint to my
explosion, I felt her orgasm, too.  In every way possible, our combined
orgasm felt better than any of the orgasms inspired by the potion.

   Afterward, we showered together, needing to rinse the mix of sex and
perspiration from our bodies.  My cock fell limp, spent from the multiple
orgasms, but she didn't seem to mind and neither did I.  After drying off,
she was the one who suggested we stay naked for the rest of the night.  As
we moved farther past the last dose of the potion, I grew more confident
that we remained naked because we were that kind of comfortable together.

   "Let's make a promise," she said after we had watched a movie together
on Netflix.  "No matter what, let's promise that we'll never lie to each
other, okay?"

   Holding her tightly against me, I kissed the top of her head and made a
follow-up suggestion.  "And that we tell each other things, too.  Like, if
you want to do something, you tell me you want to do it and I'll promise to
do the same."

   "Deal," she said, sealing the arrangement with a kiss on my lips.  "I
want to sleep with you tonight, like this.  Naked.  I want to wake up naked
with you, too." I couldn't think of a better test than seeing how it felt
waking up naked next to her.

   As the morning light filtered through the slats of my blinds, I opened
my eyes to find Carol's naked pressed up against mine.  Her eyes fluttered
and she smiled.  "Good morning," I said, kissing her tenderly on the lips.

   "Still love me?" she asked, caressing my nakedness.

   "More than ever," I said, hugging her tight so I could feel as much of
her naked body against mine as I could.

   Knowing the potion couldn't have last this long, we started our first
together as a brother and sister who truly loved each other in every sense
of the word.  I couldn't imagine a better beginning.
