I had to watch my ex fuck her new guy.Bad part was i stopped to see her her hoping i would fuck her.SHe had a guy over said just a "friend" they didnt kiss or act like they were together.We all go out come back hang out i go to bed they stat on the couch.hour later i hear some movement peek out and guy is deep in her pussy while shes riding him. and being we fucked before i know he was pleasing her.Next morning eating breakfast they act nothing happened then he walks by her gives her ass a good slap and says wanna fuck again. Was weird but seeing them have sex was great
