The Tanihara family decided to stay with their brother-in-law Kenzo for several days during a job interview. In the meantime, her wife, Nozomi, was a little nervous that her husband was not on a business trip, but before she knew it, she was enjoying her evening drink alone. However, Nozomi, whose body aches because she drank alcohol, indulges in masturbation because of the loneliness of her sleeping alone. Unaware of anything, Kenzo visits the room and finds himself in a lewd appearance that cannot be imagined from a normal sister-in-law.
