It was my birthday and for couple days already before, my ex and I had her co worker over and we had been drinking and fooling around between the 3 of us. But on my birthday i left work and my ex was super drunk and tired and i wanted to play, so we were all in the room and my ex was falling asleep and told us to go ahead and have fun. So long story short, i ended up fucking my exes friend/coworker next to her in bed. I fucked her doggy style, and she was moaning. Then i pulled out and made her swallow my cum. All while my ex slept a foot away.
