When I was 11 years old I discovered my dad's stash of porn. He had tons of dirty magazines, some showing full insertion, something rare in the early sixties. The magazines got me horny and being a born pervert I went looking for satisfaction. That is when it occurred to me that my baby sister had a vagina. she was two years old and it occurred to me that my mother might let me if I volunteered to change her diapers and give her baths. I was right. In fact she was very happy and told me how proud she was that I was becoming so mature. What she didn't know was I was using it as an opportunity to play with my baby sister's body. At first I just jerked off while fingering her but then I put my dick in her mouth and made her suck me and finally I stuck my dick in her little vagina and fucked her. I fucked her almost every day for about three years. But then when I was 14 I got a girlfriend who was 11 and she had little boobs that started to sprout and she really wanted to mess around with me a lot and when I asked her to suck my dick she got excited. After a while I talked her into letting me fuck her. Since I now had a girlfriend I lost interest in my sister. We went steady for a few years but then she broke it off when I went to college. When I came back from college my baby sister cornered me one day and told me she remembered when I fucked her and kept our secret all these years. I was 22 and she was 13 and she insisted we mess around again and before I knew it she was sneaking over to my apartment to fuck me regularly. Fucking my baby sister was even better than I remember it. Our Mom is happy because my sister spends more time at my place than at home which means my mom doesn't have to do as much cooking and cleaning and can have dates over. A few weeks later my sister asked if she could move in with me and I said yes and my mother was even happier than we were. My mom got married to her boyfriend and moved out of state. I took custody of my little sister and we lived as husband and wife. Of course that was a long time ago. Now we are both married and have children and grandchildren but we never had children together. We would have but we didn't want to make any defective insest kids.

Every once in a while, mostly at family reunions, we get together for a fuck. After all these years, my sister is still the best fuck I ever had.
