The slave lays on the couch and Natalia bounces her big butt all over his head, she grinds her butt all over his head pining him to the couch he feels helpless and is unable to get up, her butt is twice the side of his head and when she puts all of her body weight on him he is totally at the mercy of her butt, all he can do is lay there until she has finished treating his head as her seat.
