The habitual underwear thief Suzuki had once helped Ichika, who was in trouble by the roadside, and had been aroused by the sight of her, a married woman who suited thin clothing and beautiful legs. One afternoon, Suzuki went to his usual laundromat and found Ichika there as a customer. However, she seemed to be dozing off, possibly due to fatigue from housework and childcare... Taking advantage of her sleep, Suzuki retrieves the married woman's panties from the washing machine and masturbates. The next day, when Suzuki arrives, Ichika is still drowsing, and Suzuki's abnormal behavior continues to escalate.
