Me (24f) and my boyfriend (24m) were caught having sex in the living room by my mom. I still live at home, thought we had the house to ourselves. I didn’t hear my mom come in. I was on top riding him. I’m dying of embarrassment. She just left the room so fast, and of course we stopped as soon as we noticed she saw us. She hasn’t looked at me in the eyes since that day (3 days ago). Now to make things worse, my bf said he now has fantasies about people walking in on us. Particularly his best friend from high school, a girl. They were never a thing but they made out a few times. I do not know if I am open to this idea. Has anyone tried having a third person observe them and actually enjoy it?
