I remember walking to a room where my friend was with a girl. He texted me and told me he had had sex with her and sent a picture. When I saw the picture of the girl I recognized her instantly as being a coworker of mine who was very pretty and bodacious. When I walked into the room he lay in the bed naked with her. We made eye contact and confirmed he did indeed sleep with her and that it was amazing. I walked around the bed and lay next to them both on the other side and put my hand on her butt cheek. I was thinking maybe I can join in on part two but she got up shortly after and with an embarrassed smile left the room.
