"In the morning, I go to the apartment where I'm assigned, stop by the supermarket on my way home in the evening, go home and make dinner... I repeat that every day."Yuko Matsuda, 42 years old. She is a condominium concierge who has been married for 14 years and has two children who are in elementary school. She finally got married to her husband, who was her classmate in school, after dating for six years. Although they still have sex three times a week, Yuko feels unsatisfied with the "stimulation of the brain" that she cannot get by just inserting it in her vagina and shaking her hips. "When I usually work in this outfit, some of the residents become friendly and ask me out. Personal contact is prohibited by the rules, and I know they're joking, but when I think about it, I get excited thinking about what would happen to me if that happened." This wife decided to appear in an adult video on the condition that she be given an alibi, and this is her first experience of infidelity.
