SSIS-600 Every night, having sex non-stop until the laundry is done with a completely defenseless and full-of-flaws wife who falls asleep at the coin laundry. Hoshimiya Ikka.

Suzuki, a repeat offender who wears underwear outside his clothes, once helped Ikuka, who was in distress by the roadside. He had become aroused at the sight of her beautiful legs and how she looked in light clothing. One afternoon, Suzuki went to his usual laundromat and found Ikuka there as an earlier customer. However, she seemed tired from housework or child-rearing and was dozing off… asleep. Taking advantage of this, Suzuki took the married woman's panties out of the washing machine and masturbated. The next day, when Suzuki went again, he found Ikuka dozing off once more. Suzuki's abnormal behavior continued to escalate.
