I grew up with three sisters, my middle sister who was two years older than me was obsessed with me being a boy. she teased me, she block and tacked me and called me a sissy because I wasn't stronger than her. she would grab me by the balls and squeeze me until I said uncle. she would get in the shower with me and wash me. she would do anything to play and touch my penis. if she got an erection out of it, she would rub it against her cheeks, making noises. then one day, she put my penis in her mouth and she sucked on me like it was a lollypop. All this before I turned 10.

about that time, she decided it was time that a I learned about her, and she started having me touch her, she liked to have me take the palm of my hand and just rub her hard while she lay on her back. at the time I didn't know it, but I was rubbing her until had an orgasm, and soon as she did then she would tell me to get away.

I was 15 when she had me have sex with her, she was careful to make sure that I ejaculated on her, not letting me ejaculate in her. even then I didn't like that. I would guess we had sex several times a month. by the time I graduated from high school I knew more about sex than any of my classmates, I never told any one about what we did.

to my surprise, one Christmas, we were all together because my mother was sick, and my oldest sister told me to take care of my sister. I asked her what she meant, and she said 'you know, take care of her, like you did when you were at home'. that is when I found out my other sisters knew all about what my sister and I did growing up. I went up stairs to find out what was wrong, and I found out my sister was getting a divorce. I took 'care' of her.

My sister and I have an unforgiving relationship, we always have. I suppose we always will. She is the only woman that I can have meaningful sex with. I just don't feel anything with anyone else.
