William's training is frequently painful and often humiliating. Whenever he chooses the wrong answer on his Slave Assessment Programme, a steel strap strikes his ass. He learns how to pleasure breasts by nibbling and licking latex tits; the better he does, the fewer paddle strokes he gets afterwards. He's forced to cum on command, sometimes while being humiliatingly milked. When his wife, whom he now calls "Mistress Penny", comes to visit, he begs her to take him home, but she insists that he isn't nearly submissive enough yet. The meek little dishrag that he married has now become a strong and clever Domme. She's even taken over his job, and is doing it better than he ever did. Impulsively, William loses his temper and shouts at her - big mistake! As his first punishment, a small, spinning wheel throws weighted knots at the head of his cock faster and faster until it's a blur of motion. His dick is in agony! 109 pp.
