hah, that sounds like it was one hell of a time... the young rush, the climax as you let loose inside her.
i was 27 at my old friends (no longer friends as he slept my wife) bachelor party.
i was getting a lap-dance and i came inside my pants when she was rubbing her ass on my crotch, and she told me something i think like "hey, i'll show you where you're supposed to cum." so yeah i was sweating and all that shit, and she brings me down into the basement where there was a mini bar and a TV a few raggedy couches and all that. she takes off my pants and starts blowing me to get me hard again. it definately worked for a bit! then she got on top of me while i was sitting down and tried to fit me inside her. it was hard because i was going flaccid, but i did get it in for around 10 seconds before i went flaccid again. then for about 20 minutes she just rubbed her pussy against my cock.
it was really cool, won't forget that one! lol.
cheers
