My Sister Cheryl (sibling incest, cross dressing, panty-pooping, light
scat) ADULTS ONLY copyright: 2005

   My sister Cheryl and I had always had a close, if not precisely
traditional sibling relationship.  Growing up without a father-figure, I
had no-one to model masculine behavior for me to imitate.  Added to this
situation was the fact that our mother had to be gone on business most of
the time, in order to support the private tutors who educated us.  From an
early age, we were each others only real playmates, living on a secluded
farm in up-state New York.  Cheryl was my principal role-model, and my
mannerism developed with a decidedly feminine slant.  Eventually I began to
be bothered by the fact that I wasn't biologically female, since females
were the only others around it seemed.  Cheryl reassured me though that I
didn't have to alter my behavior in anyway-in fact she said she even
thought of me as her little sister.  From this point on, my relationship
with C was sealed, I wanted nothing more that to be her cute little sister,
and was overjoyed when she began dressing me each day, in the clothes she
had out grown.  My favorite was her old school uniform, and that is still
my favorite outfit to this day, when combined with a pair of cute white
satin panties, with just a touch of lace at the waistband.

   Together we played dolls and doctor, horsie and house, often taking long
walks and picnicking in the pleasant green countryside.  One day when you
were fourteen and I was ten, after a nice picnic, we both began to feel the
need for the toilet, however there were none anywhere near.  I began to
squirm around in desperation, with my hand pressed between my legs, and my
legs pressed tightly together.

   "What's wrong baby sis?" you cooed, lightly and playfully tugging on the
curly pig-tails that you had put my hair in earlier.

   "I have to go potty," I whispered urgently as though people could hear
"and I can't hold it much longer!"

   "I do too," you replied and then after a moment to think "tell you
what...there's nobody out here, so why don't we just go in our panties like
when we were little?"

   I giggled in spite of my urge, and then without really even considering
it said brightly "O.K." In fact though, I had no choice.  My bladder let go
and soon there was a warm stream running down my legs.  I quickly assumed a
squatting position so as not to soak myself completely, allowing my piss to
run straight down out of my panties.

   The look on my face must have been obvious and enticing, and soon you
too are squatting down in front of me, hold my hand as you wet yourself. 
"Ooh it feels nice doesn't it sis?  Just letting yourself go ahead and wet
your panties is so nice." you sigh.  I later realized of course that you
were old enough to truly be turned on by this, and although I was too, my
capacity to understand just wasn't yet there.  "I have to poop as well."
she whispered, and so did I.  My little sissy-girl ass was indeed quite
full, so much so that my tummy was bulging a little.

   "Let me go first." You said breathlessly.  "That way you can see me do
it and it will be easier." That was my sister, always looking after me.  I
felt so loved that she would intentionally push a big load of stinky poo
into her panties for me.  I told her this and she smiled at me, still
holding my hand, as she began to push.  "I can't believe I'm doing this
Wylie, I'm going to shit my little panties right here with my little sister
watching me!" Indeed I was watching.

   "Sis, turn around and lift your skirt up so I can see you do it!" I
said, breathless too now with the dirty act we were both about to willingly
commit.  You bottom looks so pretty to me, encased as mine are in a pair of
very feminine satin panties, although yours are bright pink.  My fingers
travel to touch your ass lightly and you gasp as I do.  Now however, the
time has come for you to fill your knickers with shit.  You pass a little
gas that wafts up to my nose, but I am so entranced by our actions that it
doesn't smell bad at all.  In fact, I like it.  A lot.

   Now I hear a strained grunt as you push down hard.  There is a soft
crackling, squelchy noise as your panties suddenly balloon outwards in a
large mound.  Your mess is just dry enough not to soak through instantly,
but soft enough that I can see it squeezing into every contour of you body,
down into your crotch, and up into the cleft of your ass.  "Oh god..." you
hiss urgently as your mess fills your pants "this is so good...feels so
good...."

   I am now bursting with need to poo, and having seen your reaction,
bursting with the desire to dirty my own sissy pants.  In my own case, no
straining is necessary, and soon the air is filled with the scent of two
dirty girls who intentionally poo-ed their panties.  My tender young anus
stretches suddenly and then I can feel nothing but a soft warmth in my seat
as I helplessly shit myself.  You gather your little sister into your arms,
smiling as you inhale the strong smell of shit we have produced together.
As we embrace, our hands instinctively find their way to each other's
bottoms to press our poop up higher between our cheeks and out across the
globes of our asses.  Then, hand in hand, we make our way home, savoring
the warm messes that caress our bottoms as we do so.  Catching Up

   To celebrate my ascendancy into young adulthood, I went to visit you in
you the place you now call home, southern California.  I've learned to
guard my true nature, but I am overjoyed to find that once we are home from
the airport you want nothing more than for me to be your little sister
again.  "This is California sweetheart, you see all kinds of things here."
Without another word we dash upstairs for you to dress me, and do my hair
and makeup.  I love the way you pamper me like a little doll, making a fuss
and telling me what a cute sister you have.  There's no need for blush, as
I am positively glowing with your praise.

   "I go to a nightclub where there are always lots of boys in skirts!" you
grin.  "Tonight, I'm going to take you there." With a head full of ganja we
head out the door.  You've dressed me a little more adult now I realized,
pleased that your outlook on me has matured a little, even though I know
I'll always be your little sister-pleated skirts are my favorite you know.
That thought makes me smile as you drive us downtown, my head swimming with
the glow of the city lights.

   The dark and noise of the club is a little intimidating, but you take my
hand in yours and give it a gentle squeeze to reassure me.  "It's a little
more quiet in the back." you shout, and so we make our way to a secluded
booth.  For the first hour, we simply catch up on our lives, paying no heed
to the fact that we have been downing drinks continually.  Eventually
however the drinking catches up with us and I realize that I need to pee
desperately.

   "Cheryl I can't use the guys, I just can't and they won't let me use the
girls!"

   "Sweetie, with this thick carpeting, the noise, and the dark, we could
piss our panties all night and no one would ever know!" you smile
lecherously, and I giggle in spite of myself!

   "Piss my panties in public?  Are you serious?"

   "As a heart attack sis.  How about if I do it with you?  I'll be just
like old times!"

   With that, my mind began to wonder back to that day long ago when we
deliberately pissed and pooped ourselves.  With my skirt pulled back, I
scooted to the edge of my seat, and began to let go.  You grasp my hand and
pull it between your legs, and I am rewarded by the feel of your hot urine
soaking you pants crotch.  My cock instantly springs to life, although not
enough to inhibit my pissing, knowing that I'm touching my sister's wet
panties and willfully pissing my own.  You press my hand hard into
yourself, and gaze into my eyes as my fingers begin to feel wet with
something other than your warm pee.  You have never looked more beautiful
than now, and I realize that I am truly an adult, with an adult's passions
and needs.  With your other hand, you gently begin to caress the stiffness
that presses out into my knickers, and your face leans closer.  I can smell
your girlish scent, so achingly familiar and wonderful and as our lips come
together, we release our bladders completely in a hot searing panty-pissing
kiss that has been coming our whole lives.

   My head is spinning with desire and there is no doubt that we should be
leaving.  I sigh.  "Can we go?  I have to do more than just pee."

   "Of course baby sis.  Let me take you home where we can play."

   We are both a little tipsy as we head out the door, leaning on each
other for support.  As we walk the few short blocks to the car however, my
intestines flex with need, and I realize that a huge column of poop has
slid down from my colon to completely fill my little rectum.  I squirm and
walk gingerly, trying to keep from pooping my panties in public.  I am so
wrapped up in my own pressing need that I do not notice your own actions,
which mirror mine.  As we approach the car I hear you hiss "Oh sis, I can't
make it!  I'm going to mess myself!"

   Finally I realize I can't hold it either.  I look into your eyes and
wrap my arms around you.  "Let's just give up Cheryl...let's not even
try...." And with that we lean against the car and our lips come together a
second time, only this time, we relax completely into each other, the
simultaneous anal release causing us to gasp with desire as we begin
shitting great stinking brown messes into our panties.

   The drive home is a blur.  It probably wasn't a good idea for us to be
driving at all, but neither of us was about to chance a taxi with our
panty-bottoms sagging with so much hot shit.  The hot poop squeezes
delightfully against our bottoms as we settle into the cool leather seats
of your car.  For the duration of that short ride I lay my head in your lap
and you stroke my curls as I inhale great lungfuls of your sexy shit scent.
"Oh sis" I cry out helplessly "Your poop smells so good!  Can we stay like
this for awhile, please; I need to smell your poop!"

   "Oh you are a dirty little sissy aren't you?" you smile, without a hint
of malice.  It's true, I am your little sissy-girl, and I now know that's
all I want to be.

   We burst through the door from the garage, and head straight inside,
dashing up to your bedroom.  Before you can utter a word I have dropped to
my knees behind you.  "Please..." I cry desperately "Let me see and smell
your poo!"

   "You can do more than that." you smile, as you lift up the hem of your
skirt to display the bulging brown mound pressed against your gorgeous ass.
I have never seen or smelled anything as wonderful, as I bring my face in
close to you ass.  Soon my pretty sissy face is pressing into your mound,
and I can feel the moisture of your shit beginning to seep through the
satin and dampen my face with your filth.  The smell is almost
overpowering, but my desire for you is even more so.  "Yes, baby girl, push
your face into your sister's shitty panties..." you hiss, "Here's some
more!" And with that my face is momentarily pushed outwards as you force
more shit into your panties.  Crazy with lust and love I open my mouth and
begin to drag my tongue across your shitty panty ass, tasting for the first
time, my own sister's stinking shit.

   "Yes...yes...lick my pooped panties..." you moan obscenely, making a
gentle circling motion with your hips, to gradually smear your hot poo all
over you ass against my slut face.  Slut.  Yes, that's what I am...a sissy
slut, for my sister, an incestuous little shit-slut for my big sister.  I
sigh happily burying my face into you, listening to the squelching noises,
delighting in the way your panties conform to the shape of my face as I
press it into your shit.

   "Does that taste good baby sis?" you smile adoringly down at my face,
which by now is faintly tinged with a thin sheen of brown, my make-up
having smeared rather whorishly on my face.  I notice a cute red lip print
right in the center of you panties, right over your anus.

   "I love your poo taste sis!" My voice shrill with my sissy desires.  At
this point I just want to be your toilet slut...anything to show you what I
sissy-shit girl I am for you.

   Soon however, you want to join in our filthy play, and without a word
you pull me up onto the bed with you.  Our hands find our way immediately
into each other's pooped panties.  We no longer care about the smell or the
fact that we haven't even undressed, although we now begin fumbling to get
naked.  Our hands however, are already covered in shit though, so our
clothes are quite soiled.  Our shitty fingers play in each other anuses,
massaging our shit into our asses, and finally bringing them up to rub
against our bellies, our breasts, and across each others faces.  We finally
orgasm together as we share our first shitty French kiss, exchanging our
shit lovingly in each other's mouths.  Finally, stripped down to nothing
but panties, we roll into the satin sheets, making your bed filthy, knowing
that we will sleep tonight, bathed in each others shit, as we were always
meant to.
