One of my wife's current favorite fantasies is to have a regular bull (don't have one atm) that takes her home to his house and have a few of his friends come over.
She would get fucked in the bedroom by all of them one by one while the other are chilling in the living room.
In her perfect fantasy I would be there as well to chill with those guys in the living room as well, while listening to her screams from the bedroom!
I don't know about that last part though
