When I was in eighth grade whenever I wore sweat pants to school I would get a hard on. I would always have it covered up with a book or sport shorts. One day in the hall I was talking with some friends but not looking where I was walking and bumped into a girl. She turned around quickly and her hand touched my hard on before I could cover up. She looked down, smiled and walked away.
After school while walking home I passed the girl who I had bumped into. She stopped me and asked if I was ok. I looked at her and she looked down at my crotch. I said I was sorry but I can't control it. As she was looking at my crotch I started to get a hard on. My sweatpants pointed out and she laughed. I told her it happens when I look at a pretty girl. She told me to come into her house. We went up to her room and she asked if she could see it. I asked if I could see her breasts in exchange. She told me ok.
I took off my sweats and underwear and her mouth dropped open. She asked if it hurt. I told her only if I don't play with it. She told me to play with myself. After a few minutes I started to shudder and came all over her shirt. She was amazed and told me it was the first time she saw a penis and a guy cum before. She looked at me and took her shirt and bra off. She had perky breasts but big nipples that were hard. She then took off her jeans and panties and I saw her vagina and hair. I got hard again in two seconds.
We touched each other and she massaged my penis to another orgasm. I played with her vagina until her body started to shake and she had an orgasm. We both lay there catching our breath. After a few minutes she looked at me and said getting the point from you was great.
