The Dominatrix purchases two used male masochists from a servant market, choosing one to keep as her pet while returning the other due to poor performance. The servants must obey the Dominatrix's strict rules and endure various trials. They compete in diverse challenges such as shoe licking and polishing, catching snacks mid-air, guessing vibrator colors anally inserted, tug-of-war, and dropping weights using only their erect penises. Other contests include ejaculation races using Dutch wives and blindfolded bone-fetching like dogs, all of which greatly entertain the Dominatrix. They traverse endless human carpets and participate in horseback riding time trials. The Dominatrix uses a single playing card whip to test their luck, quizzes them, and punishes incorrect answers with candle wax torture. Desperate to avoid being returned to the market, each male masochist pushes his limits, faithfully obeying every command.
