So the MC (uke) is the head of a mafia(or something like that) and he has 2 bodyguards (both are seme). In the past, the uke got kidnapped by another mafia and the both seme saved him and since then they have sex with the uke to satisfy his sexual needs due to the kidnapping (i guess he was raped ).
Looking for a yaoi where the main character (uke) is in love with a colleague at work. Someday he thought he had sex with a dude in his dream but it was actually a ghost. The ghost started following the uke, he took possession of the uke's crush at same point and later on another ghost sexually attack the uke and the main ghost help him after watching for awhile
