The housewife Sumire is in her second year of marriage. She lives with a kind and hard-working husband. The only thing that is not satisfactory is that her gullible husband is not very positive about their night life. From that week, the house renovation work began, and a middle-aged craftsman, taciturn, quiet, and tough-looking, came to work at the house. A craftsman who only responded with a curt and unfriendly answer when approached. The smell of male sweat that he emitted made the married woman wet her crotch. And then one day, because she was so horny, this slutty wife did something no one expected.
