Cute girl I had met

up with a couple of times with groups of friends and I decided to go out and have some drinks ourselves. Things are going really well and we end up going back to her place. We are on her couch and watching a movie and stuff and we continue drinking. Her rommate comes home, interrupts us for a few minutes, and we basically just pass out. I was laying on the floor on a pillow and she on the couch. About an hour or two I'm awakened by rustling only to look up and see the girl pulling her pants down and peeing on her own couch. I went to her roommates bedroom door, knocked on it, told her that they had a cleanup ahead of them, and left.
