Julia-Eva steps over her slave and drops down, ass first, on his belly.
Riding reverse and sideward, should make him common with her weight.
Then she turns around and sits foreward on him.
She sits on his throat and clamps his head between her fleshy legs.
The it's time for pounding his face with her ass....
Under this mass of soft flesh it's a nice place to be, but hard to survife without airsupply.
