Housewife Yumi was troubled by her only son's delinquent behavior. One day, she found herself forced into a sexual relationship with a student teacher—an unbelievable incident that left her overwhelmed with disappointment and guilt. That day, Yumi went to apologize to the vice principal. When she deeply expressed her remorse, he demanded not just verbal apology but physical sincerity, groping her seductive body and creampieing her. Later, she was summoned to a hotel, dressed in a gym uniform and bloomers, and tormented with a vibrator while drowning in pleasure. Lost in this surreal experience, she ecstatically accepted thick cum deep inside her vagina, transforming instantly into a masochistic, depraved wife.
