Ok this is one of the wildest forms of movie out there and I've only found a few that push to kink to new levels. A gloryhole is just a hole, cut between two rooms, where a guy enters one and the woman is on the other. He sticks his cock thru the hole and the woman mounts his cock until he squirts off a load of cum inside her pussy.

Well a gloryhole is just a hole, cut between two booths a bathroom stall or some other type of wall. The hole is located at a point equal to the distance from the floor at a mans cock is so that he can stand at the hole and be serviced from a person on the other side. The hole is normally only large enough for the mans cock but some are large enough to allow a hand thru but never any bigger. The ways its used is obvious, a guy would stand at the hole and put his cock through so that the person on the opposite side could have fun with it through some form of creampie sexual activity.
