A dominant woman, Mistress, takes her new slave through rigorous face-sitting training. She mounts his face, her ass engulfing his nose and mouth, cutting off his air supply. He gasps and chokes, but she commands him to stay still, enjoying the sensation of his helplessness. She grinds her ass onto his mouth, forcing him to lick and kiss her pussy and asshole. The session ends with her climax, her juices dripping onto his face, marking her dominance.
