Two of my friends and me took turns fucking a girl back in highschool.
We were hanging out at this friend's house, I was talking to this girl and she came over after school.
I knew she was into some freaky shit, long story short, I asked my friend to use a spare room,went to the room with her, we had sex, then I came out and she called one of my friends, and when he was done the other one.
I had sex with her a couple more times after that.
