As a pervert who likes women's panties, the laundromat owner is lucky to meet a prostitute Yuki - a married woman who is always dissatisfied with her bed. Because the washing machine at home was broken, during one time she brought her clothes here to wash, she accidentally dropped her underwear outside without noticing. The next day, after the laundromat owner's offer to go to his house to deal with personal needs because there was no toilet in the salon, she found her underwear on his bed. That evening she came and insisted that he let her into the house to check on his underwear, which he couldn't hide, so he told her the truth about his hobby of looking at panties. Suddenly, not only did she not scold and feel disgusted, but she also continued to want to show him the underwear she was wearing on her body at that time, but on the condition that she had to help her satisfy her sexual needs.
