Beautiful Mistress Mercy is trampling her slave and as the camera moves up from her feet to her ass you get an amazing view of her perfect 'made for face sitting' butt. Plump and fleshy she says it's just one of the reasons slaves endure being stepped on by her, the anticipation that she might sit on their faces and even better fart on them. Mercy walks all over her slave, jumps on him and even stands on his head. To add some humiliation she rubs a sole over his dripping dick and then makes him lick the foot clean. She shares some humiliating ideas she has for this slave and the other locked in the cage. She has the slave turn his head sideways to step on it then gets off and tells him to turn it upwards and she gives him what he has been praying for, her ass on his face.
