That would just be Spoiling him

Mistress Kassy looks like the girl next door but don't let looks deceive you, she loves nothing more than seeing men suffer for her. This scene opens with her sitting on her slaves face. "I'm testing his endurance to see how long he can hold his breath" she says. She gives him a breath and then sits down again. She counts the seconds until she says she has lost track of time but by that point it has been over a minute. The slave is now kicking. She gets up casually and the slave gasps for air. Pleased with him Kassy removes her skirt revealing a sexy pair of black panties with her ass fully exposed. She stands over him and tells him he is so unworthy. "Are you ready to hold your breath some more?" she asks. Naturally he is, what fool could resist that sweet young ass on their face.

She sits on his face and says "I love feeling a slaves nose right on my butt." She strokes his cock a bit and notices that it's leaking. "Too bad he can't see my butt" she says, looking at the camera and adding "But you can." It looks amazing sitting on a face.  She sits firmly until he struggles for air but then starts bouncing on his face. She likes seeing how erect he is and tells him to stroke it. "I bet you'd love to cum under my ass, wouldn't you?" she says and suddenly after just a bit of masturbation the slave blurts out that he is about to cum. She pulls his hand away and says "Not today." Poor sap doesn't even get a ruined orgasm out of it. She lays back on the bed and tells him to worship her feet. "He got my ass and my feet, surely he doesn't need to cum as well, that would just be spoiling him" she says with a smile.
