What's your worst one night stand experience?

this is so embarrasing but here goes.. so last night I was at a club with some of my friends, and i've seen this friend-of-a-friend around a few times.. we were clearly attracted to eachother but never did anything because I was in a relationship.. well, I was hoping for a rebound and he was the perfect choice (lol no). anyway, after a while on the dance floor we decided to go to his place. so everything was fine at first; we made out a great deal and things escalated quickly. we ended up doing sexy time for maybe 2 minutes until his dick slipped and he shoved it up my bum! I seriously felt like I was going to die. I cringed in pain and actually cried because it hurt so much. After the initial shock of what had happened we just laid on his bed awkwardly saying how the mood is totally killed and how fucked up that was. So after the pain subsided enough we began kissing again but I had to pee, so I got up to go to the washroom accross the hall and I was scared shittless by some fat hairy man in tighty whities wearing a flashlight on his head! It was his father, and it was mortifying. I went pee and then left abruptly after that. Too much awkwardness in one night.. We both promised not to say anything about it to anyone though.. Oh and I forgot to mention we go to the same school so from now on every time I'll bump into him in the halls all I will think of is his penis intruding my asshole and his hairy father. yup. my butt still fuckin hurts. now your turn..

TL;DR he stuck it in the wrong hole.

yeah, my story-telling skills are kinda lame.. I shared this because I was horrified by my experience and wanted to read some equally horrific one night stand stories.
