It basically started when my little sister Erin caught me masturbating. She
was ten, I was twelve. I yelled at her to get out and I was mad and
embarrassed. But after a while, I started to think about her watching
me. And then I fantasized about it. So I started to leave the door cracked
when I was jacking off, hoping she'd barge in, and one day she did. I just
looked at her and she looked at me, so I continued doing it. After a while
she said she was going to tell Mom and I said I'd tell Mom she was watching
me. She ran out of my room and I shut the door and locked it.

After that I got real worried. I thought she'd tell on me but she never
did. It was about two weeks later when she knocked on my door. I wasn't
jacking off or anything. When I let her in she looked real disappointed.
She asked if she could watch me play with myself again. I said only if she
didn't tell and she said she wouldn't. So I pulled my dick out and played
with it until it was hard, then I sort of stroked it for a while in front
of her. She would stare at my dick, then glance up at my face, then stare
down at my crotch again. I couldn't cum yet so nothing really happened.
Finally I asked her if she had enough and she shrugged, so I said that if
she didn't want to leave she could play with it. I think my exact words
were, "Why don't you beat me off." Then I stuck it in her face and she
played with it, and it felt really great. She was smiling and blushing and
everything.

So then we'd do it when we could after that. I told my friend Gary about it
and he wanted to see it happen, and he also wanted her to do it to him. The
next time he spent the night we were all in the basement together and I
nodded at Gary and we pulled our penises out. It was the first time I'd
seen Gary's dick. It was like mine, but redder and a little thicker. She
played shy and shocked at first but then Erin sat between us and played
with both of our dicks at the same time for like a really long time. Then
Gary asked if she ever sucked me and I didn't really know what he was
talking about. So he told Erin to put his penis in her mouth and she was
like Ewww, no way. And he said it was no big deal and then he got down on
his knees and put MY dick in his mouth! I was like, holy shit. But it felt
great. He let Erin try it on me and she kept biting and scraping with her
teeth, so Gary kept showing her and telling her what to do. Then it was her
turn to suck him. They both wanted me to do it to him but I was like no
way. I held him and beat him off a little, and that was actually pretty
cool, but I didn't want to put it in my mouth.

Then Gary said we should take off all our clothes. Erin didn't want to but
we both said it was unfair that she could see us and we couldn't see
her. So she undressed and we did too.

Gary made Erin sit back and spread her legs so we could see her thing. He
called it a pussy and she called it a vagina. I knew both words. So Gary
and I looked at it for a while and then we all sat back and sort of played
with ourselves. Then we scooted a little closer and played with each
other. It was neat to feel Gary's fingers next to mine in Erin's pussy. It
was even cooler to feel both Gary and Erin's hands on my dick and balls.

I was so hard that my dick was sore, really sore and aching. I told them
I'd have to stop because my dick hurt. Gary said his hurt too. So we got
dressed again and Erin went to her bedroom and Gary and I went to mine.

Gary would spend the night at my house about once a month after that and we
would always mess around with Erin. When we wasn't there Erin and I would
mess around too. It never went beyond touching and sucking until I was
fourteen.

I started cumming when I was fourteen. Then it was just sucking, all the
time. Erin would go down on me whenever she could and drink the cum. And
when Gary came over she would do him too. There was a couple of times when
Gary would spend the night and Erin would be gone, spending the night at
her friend's house or something, and Gary would want to mess with me and I
would let him. He never made me suck him but he sucked me all the time.

When Erin turned thirteen she acted like she didn't want to do it any
more. I would come into her bedroom and pull my hard dick out and she would
be all, Eww, get out, I'm telling Mom. But she never told. And she would
come into my bedroom at night and get in bed with me and actually make out
with me, with kissing and everything, before she would suck me.

We had sex for the first time when I was sixteen and she was fourteen. It
was kind of an accident. We were both completely naked in my bed, making
out, and she was on top with both legs around me and we were grinding our
hips together. And suddenly it just went in and I was inside her. We both
froze, and then after a second we both started moving, and then we were
fucking. We both knew better than to have me cum inside her so I pulled out
and she sucked me when I came. After that I stole a bunch of condoms from a
drugstore near my school and we would fuck a lot.

I had girlfriends most of this time, but even when I had girlfriends that I
messed around with I would still fuck Erin and let her suck me. Erin had
boyfriends too but she didn't mess with any of them, or at least that's
what she told me.

One night we were fucking and the condom broke and we didn't know it until
it was over. Then we both totally freaked out and were worried for
days. She made me shoplift a pregnancy test from the drugstore, and man,
when we found out she wasn't pregnant, we were so relieved. We were scared
of sex for a while, and then around Christmas she came in my bedroom one
night for sex. I told her I didn't want to fuck any more because I might
get her pregnant if the condom broke again. She was mad but I said I would
show her something new I had heard about.

That was when we started 69ing. She really loved for me to lick her pussy
while she sucked me. It was easy for both of us to cum that way. I had
heard about pussy licking before this and I didn't want to do it, but when
she was mad I thought that I could try it and maybe she wouldn't be mad if
she liked it. And she loved it.

So now I'm nineteen and she's seventeen. I'm in college and I don't see
Erin much. She's a senior and she'll be graduating soon. She applied to the
same college I'm in, so maybe we'll be able to do it more when she gets
into this school. Right now we can only do it when I come home to visit,
and we have to drive out somewhere and do it because my parents moved into
a smaller house when I moved out and there's no place to hide and no locks
on most of the doors. So Erin and I get a hotel room, or if the weather's
nice we just go to a corner of the park with a blanket.

I love having sex with my sister and she loves it too. I guess that's all I
have to say.


THE END
