Reiko is now the sex slave of her step-son, Sota, who she remarried. When her husband goes to work today, her son plays with her as he pleases. She is forced to deep throat a vibrator and moans silently as her husband sleeps next to her. Sota then goes even more out of control and calls his friend to give him sexual service. She is intimidated by her son's intimidation and her body becomes increasingly sensitive, trembling with fear.
