Input: Text: so is happend a while ago
happend last year while i was having a "thing" with this hot girl i knew (smart as a cracker but who cares).
anyway there were a lot of partys at the time and each time i ended up at her place totaly drunk. we started kissing each time but that was about it.
so this one time she promised me beforehand that we do some "stuff" today. i got as excited as i got drunk (a lot) so at around 2.00 i went over to her and told he to hold up her promise which she did so we went back to her place whilst kissing.
fast forwarding a bit. so were in her bed topless and she starts grinding me furiously. she was so good at it that i though i might just stain my pants white but to stupid to realise that we also just could have had sex.
so the gloriously stupid me stopped her since i didn't want to ruin my pants. we went out for a smoke and then went to bed. with clothes on.
