===== SIS'S BUTT SOLVES OUR PROBLEM =====

	I can't remember exactly when my sister Nancy and I first began
masturbating in front of each other, but by the time we were in
high school, we would usually come home after our dates with
other people and tell all about what Nancy called "the juicy
details." My sister is a beautiful brunette with smallish-sized
tits.  I'd tell about dry humping my date in the front seat, or
touching some girl's tits; and Nancy would sit back against the
headboard of her bed and slowly bring her knees up, then open her
thighs. As she listened to me describe my sexual adventures,
she'd moan a little, and begin rubbing her pussy through the thin
cotton of her panties. 	While I watched, eventually she'd pull
her panties off, let her skirt slide up to her hips and expose
her naked pussy to me. By now my dick would be getting very nice
and hard while I told what I'd done with other girls. Nancy would
put her feet together, sole to sole, and spread open her legs so
they formed a diamond shape with her pussy at the top.
	Nancy's fingers would slide tantalizingly in and out of her wet
pussy until just staring at it made me so hard I'd have to take
out my cock and jack off. I'd lean back against the foot of her
frilly bed while she lay up at the top and we'd masturbate
freely. Both of us watched each other's aroused sex organs as we
played with ourselves.
	Nancy would pant and groan softly - our parents were always in
the bedroom next door - and stare at my cock while she teased her
pussy.  When she told about touching some guy's penis, I'd
straddle her single bed with my legs outstretched and play with
my cock, jerking it up and down faster and faster until I shot
off into a wad of Kleenex she'd hand me.
	For weeks we'd do stuff like that, until finally Nancy said it
would be more fun if we masturbated each other! I was kind of
shocked, but I liked the idea. So after our other dates, Nancy
and I always made a "brother-sister" date for later. 	Sometimes
I'd even take my girlfriend home early so I could meet up with
Nancy in her room. There I'd slid up next to her on the bed and
help her take off her panties as we "discussed" what we'd done on
our dates. We'd lay there with our clothes half off and I'd
unhook her bra and kiss and suck on her tiny nipples, making them
hard.  I'd slowly rub her pussy with my hand, then when she
started getting hot, stick two fingers into her cunt and
finger-fuck her slow and lovingly. Nancy would find a way to zip
open my fly and get my cock out and rub it good and hard while we
teased each other with our stories about sex with other people.
Then as Nancy would cum, she'd jack my cock off hard and I'd
shoot my cum into her wadded-up panties as she held them against
my spurting dick head.
	By the time we were both going to the City College, we were no
longer virgins except with each other. Oh, we'd progressed a lot,
though; Nancy learned how to suck cock, and I loved to slide my
head down between her thighs and lick and kiss her pussy until
she came. One night we got so carried away we found ourselves
naked and doing sixty-nine with each other for about half the
night. I was worried that if we kept it up we'd be fucking before
long, and that would be wrong. I loved the feel of her small
titties mashed against my skin as I sucked her clit.
	"What we're doing now," agreed Nancy "isn't incest. It's just
sucking and masturbating; but if you put your cock in my pussy,
that would be incest! I don't think either of us wanna risk
getting me pregnant!"
	"I wanna put my cock in your pussy, though," I grinned at her.
Nancy blushed and admitted that she wanted me inside of her, too,
even if I was just her brother.
	We had to agree that while we really wanted to fuck each other,
we would make a "contract" not to. If either one of us had a big
urge to fuck, Nancy said, we'd just make sure we'd make the other
one cum right away by oral sex or something. We both would cum a
lot.

going to teach her brother about fucking ...}
	After that usually Nancy and I kept our "brother-sister dates"
under control. Mostly I'd just lay on the bed with her and suck
her tits lovingly while my fingers went in and out of her snatch
as expertly as I could do it.  Nancy would french-kiss me and rub
my dick sweetly until I spurted cum into her hand. Sometimes
she'd slide down and kiss the head of my cock, then slowly lick
on it and suck it between her lips. I tried hard to hold off, but
sometimes I'd just have to cum in her warm mouth. Nancy would
groan and then swallow it!
	Then one night Nancy came into my bedroom, all breathless and
glowing, and I knew she'd really been fucked royally! "I've got
the answer to our 'problem', honey!"
	"Get your clothes off, baby brother!" she demanded, giggling and
helping me unbutton my shirt. "Boy have I got something to show
you! You're gonna love it! It's just like fucking! Actually it
kinda is fucking! And you don't have to be in my pussy!"
	Already my cock was throbbing to erection as Nancy pulled my
pants down and pushed me back on the bed. She laughed and tickled
me as we wrestled, until finally both of us were naked and
aroused and french kissing on my bed. Pulling my hands off her
titties, she rolled over and knelt in front of me, wiggling her
naked butt.
	"Come here!" she commanded, looking slyly over her shoulder as
she reached back and grabbed my hard prick and guided it up
between her buns. God, she was so sexy!
	"Nancy!" I protested. "We agreed not to...."
	"Shhhh!" she hissed, and pressed the head of my dick between her
soft buttcheeks, scooting her ass back until the tip of my prick
rested at the little puckered gray-pink ring of her anus. I
watched my oozing precum paint a little wet trail in the crack of
her ass.
	"Fuck my ass, honey, oh godd, it's wonderful!" she moaned. " 'N
it's soo nasty!
	Before I knew it my cock head was stretching the elastic flesh
of her anus and suddenly sliding inside her rectum. Her asshole
was slimy with some gooey lubricant. All I knew was that it was
an exquisite pleasure as my cock slid deep into Nancy's asshole.
The hot greasy tube of her butt seemed like the tightest, most
alive cunt in the world!
	"Awwww, yeahhhh!" I groaned, feeling my cock sink deep into her
hot ass. It was the most incredibly nasty, sexy feeling I had
ever treated my cock to.
	"Yeah, ohhh, honey yeah!" Nancy moaned. She shook her ass in a
trembling movement, and pressed back against me, kneeling on all
fours. She began ramming back until her ass was firmly pressed
against my thighs and my cock was seven inches up into her
wide-stretched butthole. She clenched her rectum and sent me into
heaven! God, the sweet way her anal canal gripped and squeezed my
cock made me want to cum immediately. I just groaned and lay my
chest across her back, stroking slowly back and forth in her
butthole as I reached around and fondled her swaying, naked
little titties.
	Nancy hissed and made oval motions with her pelvis as I filled
up her ass and fucked it harder and harder.
	In no time at all I was orgasming. "Ohhhhh, goddd Nancy, I'm
cumming! I'm cumming in your ass!"
	"Me too, unnngggg!" she panted, "I'm cumming too! Awww cum in my
ass!" 	Nancy had two fingers in her twat as she supported herself
on one arm. I went rigid and poked my cock deep into her
pussy-like ass orifice. Then I was spurting squirt after squirt
of sperm into my sister's guts; and she was whining and moaning
and orgasming as I shot!
	Later that night, Nancy rolled over where we were sleeping
together and slid under me, she got me hard again by kissing me
and feeding me her titties. When I was fully erect my sister
opened her legs and bent up until her whole crotch was open and
exposed under me. I died as she grabbed my peter and slid it down
to her butt hole.
	"I wanna see your face while you cum in my ass!" she whispered,
smiling lovingly up at me. She hooked the backs of her calves
high over my shoulders and kept her ass turned up enough so that
I could fuck her butt as easily as if it were her pussy. I had
never realized that you could ass-fuck a girl like that, but my
sister Nancy taught me how. I lay on top of her and fucked her
rectum until I came and came. Nancy stared up at me, delighted at
the expressions on my face each time I shot my wad!
	Her sweet pussy scrubbed against the hair over my crotch,
dripping silvery goo down onto my cock and her asshole when she
rubbed her clit with her fingers. Her juices lubricated us more
as I fucked and fucked her butt until morning.
	I guess after that night it was only a question of time before I
stuck my cock into her pussy and fucked my sister the way we both
had wanted to for such a long time. I mean, which is nastier,
fucking your sister's asshole or her pussy? Years later now; and
Nancy and I agreed both are just fine, and she still wants to do
it any time we can!
