"Oh, Matt! Fuck me harder!"

My 18 year old, big chested, beautiful, horny cousin, Mia was screaming
with pleasure.

"Goddamn! I love feeling your cock in my pussy!"

We had been fucking like rabbits this weekend because we missed Emmy. Her
sister and my younger cousin, Emmy was out of town on a softball trip and
so our usual threesome was down to just two.

"Would you like it more in your ass?"

"Hell no!" Mia said, with mock indignation. I had been lusting after her
ass since I first laid eyes on it. It was big enough to notice, but firm
enough to drive me wild. I was plowing her pussy from behind and with her
ass right in front of me, it's all I could think about.

"Mmm! Nuhhh! Oooo!" Mia became a ball of animalistic grunts whenever we
boned. "Ok, ok. Do it!"

"Really?!" I was shocked.

"Hurry up and fuck my ass before I change my mind!"

I stuck my fingers into Mia's pussy, got some of our juices and spread it
over her virgin asshole. I very slowly slid my rock hard member into her
back door.

"Oh, Jesus! Oh, Fuck!" Mia yelped. I slid my cock in her inch by inch until
her ass was full. Mia brought her free hand down to her clit and started
rubbing herself. "Fuck my ass" was all she said. I obeyed.

I started easing in and out of her slowly, not wanting to hurt her. But
having this fantasy come true, I couldn't hold out for long. I started
hammering away at her ass and the feeling was incredible.

"Mia! Mia!" Was All I could say.

"Matt! Oh, Matt!" Was her reply.

"Ooooooooh yesssssssssss!" I groaned as ribbon after ribbon of my sticky
cum exploded into Mia's ass.

"Fuck!" was all Mia could say before I felt her ass and pussy clench
up. She started bucking like a horse and it was all I could do to stay in
her. She finally collapsed on the bed, I pulled out and spooned her.

"Oh, man. You cannot tell Emmy I let you do my ass" Mia said.

"Why not?" I asked.

"Because I told her never let a man do her in the ass unless she loved
him."

"Does that mean you love me?" I tickled her when I said it.

"Oh, fuck off!" Mia laughed. "You just caught me at my neediest time. Plus
I know you've wanted to do it forever, it's best to get that out of the
way."

"Well, it was awesome." I told her truthfully.

"Yeah, I hate to admit it, but it felt pretty good when you were that deep
inside of me."

We laid in silence for a while, until I asked Mia a question that had been
burning inside me for a while: "How did you and Emmy get...you
know...involved?"

"'Involved'?" Mia laughed. "You mean how did we get to fucking each other,
right? You want me to tell you so you can imagine it and store it in your
little spank bank?"

"Well, I don't have to imagine much. I've watched you two go at it a number
of times now."

"Well, alright." Mia said. And then she launched into it.

"Two years ago, when I was 16, I started having regular sex with my
boyfriend, Rob. I couldn't get enough. The sensation of fullness when he
was inside me was incredible, but I never had an orgasm. We would fuck
fervently in the back of his car, sometimes two or three times, but I never
could come. So when he dropped me off at home I would crawl into bed and
finish myself off with my hands. Soon Rob and I broke up, and I missed cock
so much I was fingering myself at least once every night.

I had to share a room with Emmy at our old house. One night I came home
late from a party and Emmy was already asleep in her bed across the room. I
started my nightly ritual of playing with myself and when I came I guess I
moaned or grunted too loudly.

'Are you OK, Mia?' Emmy asked. She was 13 at the time and hadn't developed
the body she has now.

'Uh, yeah, fine.' I replied, mortified.

'Then why were you making those noises?' She thought I was crying. I don't
know what came over me, but I decided to tell my little sister the truth.

'Well...I was masturbating, Emmy.'

'Whoa!' She sat up in her bed. 'I've heard girls at school talk about
it. How does that work?'

'Well, I guess I usually start by gently rubbing the top part of my
pussy. That's where the clit is.'

'OK' Emmy said. I could see her hand slip under the covers and I knew she
was touching herself for the first time. 'Oh. Oh! There is a spot that
feels good.'

'That's it.' I said 'But go easy on it to start. You don't want it getting
too sensitive.' Although I had just orgasmed, talking my little sister into
masturbating was having a positive effect on my clit, too. 'I also like to
grab my tits and play with my nipples a little.' Emmy stopped momentarily
and I could see her struggle and finally get her shirt off.

'Even if mine aren't as big as yours?' She asked.

'It will still feel good, Emmy, trust me' Emmy put her right hand back
under the blanket and her left stayed up to play with both of her little
tits.

'Mmm. This feels so good, Mia.' Emmy said softly. I was also getting
hornier and hornier.

'Ok Emmy, you can press down on your clit a little harder. If it feels
good, flick it or give it a pinch. Try the same with your nipples.'

'Mmm hmmm' was all I heard as a response. For a few more minutes, we didn't
talk, but we didn't soften the sounds of our individual pleasure. In the
darkened room, I could just barely make out Emmy's form. She seemed to
really be going at her clit.

Finally she squealed 'Oh! Oh! Oooooooh!' And her body twitched and
convulsed. The sounds of her first orgasm spent me off too.

'Oh yes! Oh yes!' I hissed as I felt the orgasm ricochet through my
body. We laid there is silence for a while, letting our breathing return to
normal.

'Thanks, Mia.' Emmy said.

'Sure thing.' was the last thing I said before I drifted off to sleep.

For the next year Emmy and I got more and more brazen with our
masturbation. We had even progressed to the point where a couple of nights
we sat across from each other with the lights on and let each other watch
while we fingered ourselves. We compared our experiences putting our
fingers, and other things, inside ourselves and how they felt, trading
advice on the subject. We never talked about it outside of our room.

One Saturday night when I was 17, I got crazy drunk at a party and let a
college guy fuck me on his parents' bed. When he finished, I asked him to
get me off and he just laughed. I got really upset, bitched him out, and
walked home.

When I got home I stumbled into our room and started loudly getting ready
for bed.

'Mia?' Emmy said groggily.

'Yeah, it's me.' I said

'I put a banana inside me tonight. It was awesome. You should try it
sometime.'

Something about having my baby sister say that to me that night absolutely
set me off. I jumped on top of her in bed and kissed her. She seemed
surprised at first, but gradually started to kiss me back. I broke the kiss
long enough to rip her sweatshirt off, exposing the 14 year old breasts
that had been growing steadily the past few months. I slobbered all over
her neck and breasts, making sure to pay attention to her rock hard
nipples.

'Mia! Mia!' was all that Emmy said while I performed on her tits.

Eventually, I kissed my way farther south and slid my tongue under the
waistband of her sweatpants. She jumped a little and I took the opportunity
to rip off the sweatpants and panties with them. I set her back down on the
bed and proceeded to gently lick her clit.

I could barely keep her ass on the bed she was squirming around so much.

'Mia! Oh, Mia!' Emmy kept up her mantra.

I gradually increased my attacks on her clit and finally stuck a finger
deep into her virgin cunt.

`Nnnnuuuhhh!' Emmy groaned and her body started convulsing. I didn't stop
my ministrations and Emmy's orgasm went on for minutes. Finally she
stopped, but her breathing was still ragged. I licked my way gently back up
her body and when I got to her mouth she grabbed my head and pulled me in
for a long kiss.

'Oh my God, Mia! I love you so much!' She said.

I laughed 'I love you too, Emmy. I always have.'

'Oh, I know' She said, but this...this is different.' We kissed a while
longer and then she said `Teach me how to do that.'

Emmy got on top of me and I told her 'First things first, suck my tits.'

Emmy went to work, gently but firmly tonguing my nipples.

'That's it baby! Oh yes!' I encouraged her. 'Now work your way down to my
pussy.' Emmy followed my every command. 'Now, tongue my clit not quite as
hard as my nipples.' Emmy obliged my silent sex slave.

'Oh, baby! Oh, Emmy baby! Yessss!' I hissed. 'Now put your finger in me.
Slid it in slow...oh!' Emmy had already anticipated me. A quick learner.
She was sliding her deft little finger in and out of my pussy just the way
I do when I go it alone. Under Emmy's increasing attacks on my pussy and
clit, I quickly came to an orgasm. 'That's it, Emmy. I'm gonna cum for
you. OH YES, EMMY! OH YEAH!'

My whole body convulsed and I got a warm feeling that coursed through my
veins. Then I went pleasantly numb. 'Come up her you sexy girl, you.' I
said to my sister. We slept together that, and every night we lived in that
house. We didn't always do each other, but more nights than not, we were
engaged in sapphic incest that made my toes curl."
