A girl taught me how to masturbate and gave me my first orgasm.
When I was eleven I lived next door to Kerry, a slightly older girl and we became quite good friends. We used to play games together, and she taught me how to play tennis. The second time we played, she hit a hard shot which caught me right in the balls. I doubled up in agony and she helped me to the side of the court.
She lay down next to me and put her arms around me, telling me how sorry she was. She kept asking me what the pain was like. She knew why it hurt of course, but didn't understand why the pain was so great. After about ten minutes, when I had recovered a bit, she asked if she could look at my balls. I reluctantly agreed, and she seemed fascinated by their vulnerability. She rolled them around in her fingers, amazed at how sensitive to pressure they were. Of course this gave me an erection which she insisted on examining.
Until that time I had got pleasure from playing with myself, but had never had an orgasm. I think she knew what she was doing though, because she started to rub me slowly up and down on the pretence of 'making me feel better'. After only a dozen or so strokes I had this unbearable rushing sensation in my penis, which was jerking around in her hand, my first orgasm! She continued stroking for a while until I started to go limp, and let go of me with a puzzled expression on her face. Of course, I know now that she had expected to see semen, and probably thought that my injury had broken me! She didn't know that I wouldn't produce any sperm for a couple of months yet.
What a shame that I was too young and inexperienced to follow up the situation and get into her pants. This experience has been the focus of my masturbatory fantasies ever since!
