This sucks.  I shouldn't have even come to this.  I sighed and slumped
against the wall, music blaring and the loud, but calm buzz of chatter that
symbolized the start of the party.  I squinted in the faint light at my
watch, 10:30.  I should have at least come at 11.  The worst part was, that
I couldn't even complain to someone because all my friends bailed on me,
leaving me not only bored, but bored and alone.  Trying to pick out people
I knew in the crowd was impossible, every single one of them had shown up
wearing a costume, masking their identity.  They weren't very extravagant,
well, some were, but even a little bit of makeup can drastically change

someone's appearance.

   I was one of the many people who dressed as a pirate, which is probably
the worst, most cliche costume in the history of Halloween, but to be fair,
I did a fairly good job at it.  I managed to scrounge around the house and
find a bandanna, a pirate hat, and a toy sword, I'm lucky that I had a
childhood to help me out on this one.  My makeup was done by none other
than my older sister, who promised that she would do it for me If I went to
the Halloween party and it was god damn frightening how good she was at it.
She'd spent an hour delicately painting on my new face while I twiddled my
thumbs and spent an hour staring at her cleavage.  I of course tried to
look away, but she'd just re-adjust my head so I was right back where I
started.  It was torture.  The way she's been teasing me recently is a
whole new level of brutal.  Always finding an excuse to bend over, leaving
her panties on the bathroom floor, having the door just a little bit open
when she's having a shower.  To make matters even more worse, she was one
of the hottest girls I have ever seen in real life with an impeccable body
- nice tits, great ass, and whatever else a man would want.  I sighed
again. It's time to leave.

   Just as I had made up my mind, the party seemed to be picking up.  Some
random pop song was turned up a notch louder than it already was, and those
who were drunk enough - the majority of the people there - started dancing.
It was dark, hot, and it already smelled like vomit in the room, but
despite how badly I wanted to leave, my sister was suppose to be driving me
back home and would freak out if she thought she lost her 'baby brother'.
My major roadblock, however was the fact that I had no clue what her
costume was, as I was out of the house before she had put it on.  I sighed
for the third time this night and wondered how I was persuaded into this
for the fourth or fifth time this night.  I wandered around for a couple of
minutes until I saw the girl with long brown hair, and great ass I was
looking for dressed as what appeared to be a vampire.  I grabbed the back
of her arm lightly.  "I'm leaving, take as long as you would like here" I
shouted over the music in her ear "Wha- oh" I heard behind me as I walked
to the bathroom of the house to rinse my face-paint off.

   I felt guilty listening to the drain gargle as I washed the last bit of
my sister's precisely painted canvas off my face.  Oh well, at least I
filled out my part of the deal.  I turned the tap off, then the light, then
made my way out of the bathroom.  I walked straight into a delicate frame
and bounced backwards a couple feet.  "Oh, sorry!" we yelled at the same
time.  Nervous laughter followed.  "I'll just get out of your way" She said
something that I couldn't exactly hear.  'Are you making your way out'
maybe?  "Yeah, I'm leaving, something came up" I quickly lied, flashing a
smile she wouldn't be able to see anyways.  "Same, this party's a drag."
Wow, bold "Agreed." I replied, nodding unnecessarily once more.  She was
closer.  "I'm a little bit disappointed, these are usually good, you know?"
I really didn't.  She said something that I didn't hear, but she was closer
than before.  "Party's are great place to make memories, I find, but I
don't think I'll make any out there" She said gesturing.  She was as close
as she could be without bumping into me again.  Her hand touched my chest
and slowly made its way down to my crotch she cupped her hand and put her
lips by my ear.  "But I might be able to make some in here."

   My skin was on fire and my blood was rushing.  Am I really just going to
fuck this random stranger that I haven't even known for a minute?  Well,
she did have a good point about the memory thing and jerking off to this
would be better than jerking off to my sister every night.  "Well not, you
know, in here here" I grabbed her hand and she navigated us to the master
bedroom, stealthy avoiding the suspicion of any of the party goers, not
that it would have mattered.  The progressive silence was music to my ears
the farther we ventured into the house.  She jumped on the bed and was
attempting to tear off her skeleton costume, but it proved more difficult
than she thought.  I fumbled around for a light switch, but found none. 
Hearing her cute noises of frustration at taking off her costume further
aroused me, and I gave up on my task, locking the door and jumping on the
bed.  I'll certainly help her take off her costume.  Our lips met and we
were locked in a kiss as my hands unzipped the back of her costume.  She
blossomed out from it and pushed me back until our positions were reversed,
while on top of me she undid her bra, still never breaking the kiss.  I
grew even harder feeling her massive breasts against me.  I took one in my
mouth - then the other.  My ears perked up as the girl spoke in a desperate
whisper.  "Please" I needed no further encouragement.  My hand reached to
her damp panties and lingered there for a moments before slipping them off
and throwing them behind me.  I laid a trail of kisses down her stomach to
her shaved pussy.

   I quickly pulled off my pants and my member lept to attention.  I slowly
entered her, my hands clenching her shapely ass and slowly moving up to her
sides.  This time, I let out my breath in pleasure not in pain.  I began a
slow deep thrust trying to savor the warmth I hadn't experienced in far too
long.  To the edge of my vision was a lamp on the nightstand, I reached for
it eagerly with one hand, the other on my lover.  Turning it on was a bad
idea.

   Considering neither of us had experienced full light for many hours.  We
grunted and waited until our eyes adjusted, but I picked up my pace
slightly, the wet slapping of skin at a nice rhythm.  I opened my eyes and
my cock jerked dangerously in excitement.

   Was I seeing this correctly?  Was something slipped in my drink earlier?
Because here I am fucking my older sister.  Is this the best luck of my
life?  Or the worst?  A few seconds later, she opened her eyes too and
matched my face of confused horror, but it slowly melted into a face of
smug satisfaction.  She bit her lip and began to move her hips with my
thrusting.  I'm still fucking her...

   I sped up further, seeking the satisfaction of watching her tits bounce.
"Oh..it's you, it's you, baby brother.  Fuck me...fuck me, brother!" This
was too much.  I could feel my cum beginning to rise.  "Fuck yeah, sis" I
said breathlessly.  I tried my best to think of something else other than
my cock inside my older sister's vagina until she spoke up.  "Please, can
my little brother fill me up with his hot cum?" Hearing her saying that
made me cum regardless.  Pleasure filled me to the bones and I shot long,
sticky ropes of cum inside her until my well ran dry.  I slumped forward,
and felt my cock soften and pop out of her pussy.  Panting heavily I bathed
my sister's large breasts with my tongue and sucked on her nipples,
something I'd wanted to do since I found out my sister was also a girl.  I
rested my head on her sweat slicked chest and we both sat there, naked, and
breathing deeply for while.

   "How did you like fucking your older sister?  Fun right?" She said
cheerfully, stroking my hair slowly.  "Mhm" I said lost in my thoughts, the
comforting petting motion further deepening my state.  "Later can we -" "Of
course we can, any time you want, little brother, but first..." She began
to sit up, and I reluctantly did the same.  She took my soft cock in her
mouth and tenderly, but thoroughly cleaned off the cum.  I played with her
hair, enjoying the feeling of my cock being licked clean.  My sister slowly
moved her mouth off of my cock and gave it a farewell kiss.  We put on our
costumes again and kissed deeply my hand smoothing the costume across her
ass.  She made for the door.  "Wait, you forgot your panties!" I called
out, gesturing to the sky blue pair on the floor.  "Those are for you, but
I don't know if you'll need to, you know, use them anymore." She said,
leaving me momentarily stunned with that thought in my mind.

   "I don't think she'll need these anymore either." I tossed them behind
me and went to catch up with my beautiful sister.  It's true what she said
earlier, party's are a great place to make memories, and I certainly won't
forget this one, or rather, my sister won't let me forget this one.
