Marcy has been told her boyfriend is still checking out other girls in the gym.

This time she makes it absolutely clear this will not be tolerated; she bounces her big ass on his chest and sits on his face over and over again smothering him into submission, at one point even smothering him for a count of 70 seconds.

He needs reminding that her ass is the only one he should be in love with; she makes him kiss and worship it.

Marcy is a natural born facesitter.
