When I was 13 I found a dirty movie my parents owned. I watched it when they weren't around and it was my first bit of sex education. I learned to masturbate by watching one of the girls in one of the scenes, and I watched the video and diddled myself every chance I got.

There was a lesbian scene in the film that I eventually showed my sister. She was 12. For the next couple of years she would go down on me while we watched the movie and I would go down on her afterwards.

We stopped when I got a boyfriend, and it's something we've never talked about. We're very close and I don't feel that way about her anymore. Otherwise, our lives are completely normal.
