An adulterous sex film of Yuki Nanao with the laundromat owner. As a pervert who likes women’s panties, the laundromat owner is lucky to meet the lewd Miss Yuki – a woman who has married but always dissatisfied in bed. Because the washing machine at home was broken, when she brought clothes here to wash, she accidentally dropped her underwear without paying attention. The next day, after the laundromat owner’s request to go to his house to take care of her personal needs because the shop did not have a bathroom, she discovered her underwear on his bed. That night she came and insisted that he let him into the house to check about the underwear. He couldn’t hide it so he had to tell her the truth about his hobby of looking at underwear. Surprisingly, not only did she not scold him or feel disgusted, but she also continued to want to show him the underwear she was wearing on her body at that time, but on one condition: helping her satisfy her sexual needs.
