Gianna Michaels is an amazon and uses her height and weight to dominate a slave and smothers him with her tits and ass. She aggressively rides his face to orgasm and then finally she sits on his face and makes him suck her pussy til she cums.

Part 2 has Jamie Elle as a bratty femdom who rides her slaves face and cums on his tongue over and over, dishing out verbal humiliation. She bounces on his tongue and grinds on his face.

A great video
