Suzuki, who is a habitual criminal with dirty underwear, had previously lent a helping hand to Ichika who was in trouble on the street, and his crotch was heated by the married woman's beautiful legs and scantily clad clothes. One afternoon, when Suzuki went to his usual laundry shop, Ichika was the previous customer. However, she seems to be dozing off because she's tired from doing housework and childcare... Suzuki takes advantage of her sleeping and takes out a married woman's panties from the washing tub and masturbates. The next day, when Suzuki goes there, Ichika is dozing off by his side, and Suzuki's abnormal behavior continues to escalate.
