I@M not sure its real, in that they were paid. If its a real event they could only be under arrest if the police were called and someone made a complaint . As long as there are no police involved and no complaint they would get away with it.
Its probably a private party and everyone knows everyone else, except for the male strippers.
So it would not involve public decency!!
I can't believe it happened for real, I mean strangers, looks like a set-up for a video.
