I once had sex with a guy in the same room right next to three other couples. It was the only place we had so we turned off the lights to make it less embarrassing. Only did it because the other three girls were friends. The problem was that the four guys wanted to fuck us all. My girlfriends were game but I was so embarrassed about it, I had to be held down by my girlfriends so they could take turns fucking me. I admit I enjoyed it, but felt humiliated having a guy fucking me and another one shoving his dick in my mouth, while the rest of the watched with the light fully turned on. Turned into a three hour orgy and the next mourning felt like a dirty slut, but so many mind blowing orgasms I would do it all over again.
