Once my ex brought her female friend over. I was horny so I push them both to drink. I drugged my gf drink but not her friend. My gf was high and drunk in not time and her friend was drunk. With music playing, they both ended up stripping and dancing naked. My gf eventually passed out on the couch. While I kept talking to her friend. There came a point that she kept fingering herself and telling me she missed her bf's cock. I was already touching her whilst next to my passed out gf. We ended up fucking next to my gf's face. I came in her. she then went sleep in the guest bed room. I woke my Gf up and had her suck my cock until I was hard again. Eventually she passed out again. So I went to her friend who was now a sleep and didn't want anymore cheating as she felt bad. I fucked her anyway. Later found out she was pregnant. It's been now 2 years since then. Not sure if it's mine or not..
