When I was 18 I was a pretty big geek just avg looking. I decided against my beter judgement to go to a party with a few friends. As soon as I walked in I saw her there a girl from my class who had been making fun of me as long as I can remember so I igonored her most of the night. Near the end of the party she was drunk and started in on me in front of her guy and girl friends. "I bet he hasnt even hit puberty yet" and so on I went to leave but she stopped me and had her guy friends hold me down. she started teasing me and asked if I had ever seen tits before. I just looked away when she took her tits out. They were kinda big for her age. She got on my lap and started grinding her ass onto my dick.
