Under the watchful eye of her Mistress, a submissive male learns the art of cocksucking the hard way. Strapped into a strapon, he's ordered to pleasure his Mistress' synthetic phallus, but his clumsy attempts only earn him a stern scolding. "You need to work on your cocksucking skills," she chides, pushing his head down forcefully. He gags and chokes, tears streaming down his face, as she face-fucks him mercilessly. His humiliation is complete when she spits on him and commands him to clean her shoes.
