   It was Christmas Eve and as we have done every year since I can remember
my immediate family gathered for a small dinner.  The big shindig is
tomorrow at my Aunt Stacy and Uncle Jim's house, but we've got this
tradtion where each of the children gets to pick one present from under the
tree and open it up after dinner.  Tonight mom made a small glazed ham and
mashed potatos.  There are some veggies, but I have no intention of eating
them.

   Oh, I suppose I should tell you about myself and my family before I get
too far into the story.  My name is Aaron Kentwood and I'm the second of
four children my parents had.  I'm 17 and a senior in highschool in case
you were wondering.  My oldest sister Amber is 20 and in college on the
other end of the state.  My youngest brother Andrew is eight years old so
he's still in elementary school.  He's a handful, but still a pretty good
kid.  He has more energy to burn than the sun, I swear.

   That leaves my little sister Alyssa.  She's 15 and a bit of a pain, but
a nice girl otherwise.  She never gets in trouble, but that's mostly
because she's definitely daddy's little girl.  She's in 9th grade right
now. She's not what you'd call beautiful, but with her light skinned face
and long curly chestnut hair flowing halfway down her back she is by no
means unattractive.  Her average looking body is about five foot four and
if I had to wager a guess I'd say she has generous B cup breasts and will
probably wind up with large C cuppers when she's all done developing. 
Tonight she was wearing a pale yellow knit sweater of some kind, her school
uniform skirt and a pair of white socks.  None of us likes wearing shoes
when we can help it and at home it's rare to see even one of us in anything
more than a pair of socks.  Our school's girls uniform is a blue and white
tartan skirt with a white blouse.  Most girls accesorize like crazy and
Alyssa is no different.  She usually sports a blue or white scrunchie and
whatever jewelery she feels like wearing that day.  Today she didn't bother
with either since we are on vacation after all.

   I know I'm her brother and I'm not supposed to notice these things, but
I can tell you that by far her best asset is her ass (pun intended).  It's
not as skinny as most girls in her class, but it doesn't have an ounce of
extra fat on it.  She's on the cheerleading squad so she gets plenty of
exercise.  Years of that and advanced gymnastics has left her with a very
strong, but soft rear.  I know I'm certainly not supposed to notice things
like this, but I occasionally help her and her best friend Julia practice
cheerleading One of the things required of me is to lift them both into the
air every now and then and steady each them individually with a hand on
their ass.  As such I've had plenty of opportunities to feel both of their
firm young behinds and I can tell you there is no comparison.

   I'm getting carried away here, now where was I?  Oh right, dinner.  Our
family sat down for dinner at 6:30PM and it was a nice enough meal.  Most
of the conversation was between my parents and Amber catching up on what
happened during her first semester of college.  Occasionally either Alyssa,
Andrew or I would get a few words in, but it quickly went back to mom, dad
or Amber doing the yaking.

   Dinner finally ended and mom went into the kitchen to do the dishes
while the four of us kids headed into the living room to watch TV or play
games.  Alyssa, Amber and I just chilled and played a few hands of Gin at
the coffee table.  Andrew was definitely getting antsy about opening up a
gift when mom finally finished the dishes 15 minutes later and came into
the living room to announce time to open gifts.  Andrew jumped at the
chance and more or less threw himself at the tree.  He came back holding
the gift I had gotten him and shreaded the wrapping befor anyone even said
go.  He went nuts when he saw the pair of little battle robots I had bought
him.  They were twelve or so dollars and all of their joints were magnets
so they could take battle damage, lose limbs and such.  I don't think he
was even aware of the fact that I bought them for him till I told him so
and offered to open the overengineered packaging.

   After finally liberating the contents he went about playing with the
robots while I turned towards the tree and grabbed a present at random.  It
was labled "From Amber" and was wrapped in snowman wrapping paper.  I shook
it because I sure as hell didn't want to waste my Christmas Eve gift on
clothes.  Sure enough it rattled so I went ahead and opened it.  It turned
out to be an Airsoft pistol and its accessories.  I thanked my sister and
went about checking it out.  It was a pretty nice one with a decent enough
FPS rating.  It had to cost her at least $20-30.  Sadly though my parents
wouldn't let me use it inside and at 16 degrees it was far too cold to go
outside just to try it out.

   While I was opening my present Amber and Alyssa both picked out and
opened their own gifts.  Amber grabbed a gift from mom and dad and Alyssa
picked out the one from grandpa.  Ambers gift was a rice cooker which she
thanked my parents for profusely.  Being a student she can't use a real
oven in her dorm so her diet went to shit during her first semester so she
said during dinner.  Alyssa's gift from grandpa was a new hair
straightener. After opening it she must have sat on the couch and started
going through the box.  She had been hinting about wanting one of those for
the past two months so obviously mom had bought that one for her and just
stuck grandpa's name on it.  I'm sure it was bought with his money though
so that's all good.  Do all grandparents do that?

   I got a little bored looking at my Airsoft gun so I went ahead and
joined Andrew on the floor and grabbed one of the robots he was playing
with.  I started attacking his robot while he made his robot run away.  His
robot retreated towards the couch and mine followed.  After making a quick
attack on his robot I happened to glance up and saw, not three feet away
from me, Alyssa's legs were just barely parted and the slightest hint of
her red and white striped panties were peeking out from between her legs. I
quickly looked up to her face to see if she saw me, but her nose was buried
in the instruction manual for her new straightening iron.

   Being as distracted as I was I didn't notice Andrew attacking my robot
till he had knocked off one of its arms.  I made my robot run away from his
and picked up the broken arm.  Then I spun around to see if anyone else
noticed what I had seen while pretending my robot was repairing itself. 
After I made my robot whole again I returned him to the fight and attacked
Andrew's robot.  Every time I had a chance though I stole quick glances at
Alyssa's parted thighs.  After my third or fourth peek she shifted in her
seat and moved the straightening iron's box off of her lap.  This had the
effect of lifting her skirt slightly farther up her thighs and when she
finally settled down again to continue reading the manual her legs were an
inch or more farther apart than they were before.

   Andrew had moved around and it was hard to get him back to a place where
we could keep making our robots fight while I could sneak looks up Alyssa's
skirt, but after a couple of minutes I finally managed it.  I sure as hell
wasn't dissapointed with the results.  I could see clear up to where the
panties reached the rise of her legs.  I could also see some large red
pieces of fabric at the side of her legs and wondered what the heck those
were about.  I held my gaze a little longer than I should have, but if
anyone noticed me they didn't say anything.  I directed my eyes to the spot
where her shapely thighs met and I could swear I saw a spot on her panties
that was darker than the rest.  Just then she squeezed her legs closed and
I quickly looked to her face to see if I had been caught.  Luckily she was
still reading that manual.  How the heck complicated can that thing be?

   I turned my attention back to Andrew and his robot, which was winning
the fight.  Considering how little I'd been paying attention to it that was
hardly a surprise.  With my focus back on the fight though I made some
decent offensive moves and had his robot reeling.  I continued monitoring
Alyssa and her skirt, but for the next five minutes at least she had he
legs pretty securely shut.  Out of the blue though she hopped up and
started walking past Andrew and me towards the kitchen.  As she passed by
us she asked the room in general if anyone wanted a snack.  I sure as hell
did, but I hardly think she would want to give me what I was really hungry
for.  I took what I could get though and glanced up her skirt as she passed
me and inhaled through my nose as deeply as I could.  I saw those pieces of
red fabric again and realized that they were christmas bows.  My sister's
pussy was wrapped up like a present and I desperately wanted to open it! 
After she made it to the doorway I finally caught her scent.  I smelled
whatever deoderant/perfume stuff she usually wore to school plus another
very faint scent.  At the time I wasn't sure what it was, but when I
smelled it I instantly became hornier and I could feel my cock growing in
my pants.

   "Yeah, I'll take a Coke" I finally uttered, lust coursing through me.

   "Can or a glass?" Alyssa said from the dining room.

   "Can" I replied as I continued pondering the aroma that so intrigued me.

   "No prob, Adam" she called back as she entered the kitchen.

   A moment later she was back in the living room and as she walked past me
again she handed me the drink.  I looked up as she passed and tried my best
to get a quick look back up that skirt just in case she didn't provide a
view when she sat back down.  Luck was not with me on that front, but I did
draw in another deep breath through my nose as she was right there.  Since
she had stopped momentarily to hand me my soda I got a stronger dose of her
alluring teenaged scent.  the perfume was slightly flowery, maybe lilac or
something.  That other scent though.  I still couldn't place it.  It
definitely smelled organic, like her body was producing it in fair
quantities, but it wasn't a sweaty smell or anything like that.  It smelled
sweet and sour at the same time with a hint of creaminess to it.  Whatever
the hell it was I wanted to find out.

   As I continued pondering that hypnotic odor Alyssa sat back down on the
couch and began drinking her soda.  I told Andrew that I was really thirsty
and that we'd play again later then I got up and sat in the chair across
from Alyssa.  I casually sipped from the can as I pretended to look over my
Airsoft gun again.  What I was really doing of course was trying to get
another look up my sister's skirt again.  As luck would have it she sat
down with her legs crossed a bit and I could once again see the fabric of
that interesting little bow as well as Alyssa's smooth creamy thighs.  I
enjoyed the sight while I could, but she quickly finished her drink and got
up.  "I sure am getting tired" she said "I think I'll take a shower and hit
the hay.  Mom just sort of mumbled something or other about not using all
the hot water.  Alyssa promised she wouldn't and left the room.

   "Does anyone mind if I take the next shower?  I asked the room. 
Everyone seemed to be OK with it so I just sat back in my chair, closed my
eyes and pictured Alyssa taking off her shirt and skirt then peeling her
panties down her legs and getting into the shower.  I thought of her
stepping into the steaming shower and lathering herself up.  She'd scrub
her legs then move up to her crotch.  It was a nice image, but try as I
might I couldn't help but wonder about those panties.  They were probably
in a little ball on the floor or in the hamper all lonely.  Surely they'd
rather be wrapped around my little sister's waist than stuffed away with
all the other unworthy denizens of the hamper.  Shaking that thought out of
my head for the moment I went back to picturing Alyssa bathing herself.  I
was thinking about her carefully washing her nipples and breasts when I
heard the shower upstairs finally turn off.

   I waited the customary five minutes or so to let Alyssa finish up in the
bathroom, all the while thinking about her pussy and those sad little
painties sitting with the rest of the dirty clothes waiting for their next
chance to hug my younger sister's glorious assets.  As soon as I heard the
bathroom door and then Alyssa's bedroom door close I rushed up to the
bathroom, but not too quickly as to arouse any suspicion.  I grabbed a
towel out from the closet, took off my own clothes and opened up the
hamper. There sitting atop her knit top were those beautiful little red and
white striped panties, their elaboratly large bows proudly attached to each
side as if to proclaim that what they held was so magnificent it deserved
two bows.  I reached in and grabbed them then tossed my own clothes into
the hamper.  I suddenly felt very naughty and reflexively checked to ensure
I had locked the bathroom door.  It was a good thing I did, too because I
had not.

   Now that I was safe all by myself in the bathroom I casually flipped
Alyssa's panties over a few times in my hands.  They were still warm and
smelled very strongly of that odor I had noticed before.  I knew it, I just
knew that scent had come from her pussy.  I turned the panties inside out
and looked at them.  There in the little white cotton panel was a
significantly large damp spot.  I raised my sister's panties to my nose and
inhaled deeply.  Oh my god, this was the strongest, richest thing I had
smelled in my life.  my rational brain told me that it was not a very good
smell, almost as if it were some kind of food just barely past its prime,
but my instincts told me that no, this was the most glorious thing I had
ever smelled.  My brain and my urges had a little fight just then.  I say
it was a little fight because there was no chance that my conscious mind
could have ever won out.

   After a couple of deep inhalations I started to lose my breath.  I had
to exhale at some point, but I didn't want to.  Finally I did exhale and
when I did I found myself unconciously shoving my little sister's dirty
panties into my mouth.  When the taste hit my tongue I just lost it.  My
penis, which was already fairly stiff shot to full attention and my free
hand unconsciously moved toward it while my mind did loops.  I was in
heaven and as soon as I grabbed my dick I launched a load of cum across the
room.  "Holy shit" I thought, "I barely so much as touch myself and already
I have an orgasm?" I usually can't even get off in under five minutes while
jacking it liker a mad man.

   Feeling completely spent I sat down on the toilet and gasped a few times
till my heart and lungs finally caught up to me.  I pulled Alyssa's dirty
panties out of my mouth and looked them over again.  Now the entire cotton
panel was not just damp, but soaked with my saliva and what was left of my
sister's secretions.  Again I shoved my nose into the wet morsels and
inhaled deeply several times.  I received the second shock of the past few
minutes when I felt my just spent cock start to once again stiffen. 
Determined to enjoy it this time I wrapped my hand around my shaft and
slowly pumped it as I continued sampling the addictive aroma of Alyssa's
pussy from these little red and white striped treasures.  As I pumped my
cock I laughed to myself at the idea that for who knows how many years I
have been living with a pair of sisters who left the most alluring
substance on earth just lying around for the taking.  Right then and there
I decided I'd be doing a lot more taking in the future.

   My cock was fully hard once again so I went ahead and shoved Alyssa's
panties back into my mouth.  The strong flavor once again assaulted my
palate.  This time though I decided to take it easy and enjoy what I was
tasting as well as what I was feeling.  My little sister's flavor was like
nothing I had ever tasted.  It definitely had a creamy flavor to it just
like what I had smelled earlier, but there was something else to it. 
Almost as if someone had added honey or something to the mix.  But what
became overpowering was an almost putrid flavor.  Once again my mind was
screaming at me to take the panties out of my mouth, but my penis was
firmly in control now and I easily stifled that thought.  This was such a
strange experience.  I was literally disgusted, not only with myself for
what I was doing, but for what I was tasting.  For it being such a sweet
inviting smell Alyssa's pussy sure did taste...  not so good.  In fact yes,
I decided it tasted downright bad and bordered on sickening, yet there was
no way I could possibly tell myself to remove the panties from my mouth, so
I continued sucking on them as I pounded my penis with a force I'd never
used before.

   I felt my orgasm rising once again and a twisted thought suddenly
entered my mind.  I pulled my sister's panties out of my mouth and held
them out in front of my cock with my left hand while I continued to abuse
myself with my right.  In no time at all I felt the familiar spasms and
came for the second time in less than ten minutes.  I blasted a thick gob
right onto the wet spot my mouth left.  A second, then a third blast soon
followed and in no time Alyssa's cute little panties were filled with cum.
I don't know what came over me just then, but I found myself licking my own
cum out of my little sister's dirty panties.  I was suddenly overcome with
disgust again and finally, now that my lust was spent my mind won out and I
disposed of Alyssa's thoroughly used lingerie.

   Just then I realized that I actually had a purpose for being in here, so
I went ahead and stepped into the shower and cleaned myself up, thinking to
my self that no amount of scrubbing will ever clean away the sickening
person I had become in a matter of an hour or two.  Oh well, c'est la vie
as the frogs say.
