In a drunken party mood we had a MFM sexcapade with a guy that lived in our building. One day she says she and he have been fucking while I was at work. I remember he has a nine and a inch cock.They both felt like I had seen them fuck and it was my idea yo let him party naked with us the first time. First I was pissed but I had opened the door by sharing her with a neighbor that was friend . I said if you want to keep fucking him, don't tell him I know. I as bare back? She said yes...........
