Bound and helpless, a man is subjected to a humiliating cum-eating lesson by his femdom instructor. She jerks off furiously over his face, her moans growing louder as she nears orgasm. "Open wide, slut," she commands, and he dutifully parts his lips, catching her hot, sticky load. She grinds her pussy onto his mouth, forcing him to lick up every last bit of her juices, choking him with his own saliva mixed with her cum. "Swallow it, you worthless piece of shit," she hisses, spitting on him for good measure.
