He has his friends concealing in closet (in the pipeline ahead of the intimate work can happen)and when he yells a code word like "tokyo" the friends breasts out from the closet, and te guy who is performing the intercourse act must try to stick to the surface of the girl similar to a Bull Riding Rodeo.
