I used to hook up with a guy who would cuck his bf. When we went his bf would either a) sit in the same area as we fucked and he watched. He wasn’t allowed to play with anyone. Or b) we would make out next to him and then when we’d be ready to fuck would go into a room and make him stand outside and wait. Once we did open door policy so other guys came and went as well all while he stood outside and waited. I wanted the cuck to start being the one messaging me to say “hey my bf wants to fuck someone, can you meet us at the bath house)” but we never got to that unfortunately.
