A horny sub, hidden in the corner, is caught jerking off by his dominant mistress. "I see you over there, wanking like a pathetic little puppy," she scolds, approaching him. He tries to hide his throbbing cock, but she snatches his hand away, forcing him to stroke it in front of her. "Now, listen up, little pet. You're going to learn to follow my instructions," she demands, guiding his hand with her own. She teaches him how to edge, how to slow down, how to beg for release. When he finally comes, she makes him lick every last drop off his own hand, teaching him the art of humiliation and domination.
