My aunt, Ai, who returned from the United States, suddenly came to my nephew, Toshiya's apartment living in Tokyo, and decided to stay for three days. Toshiya's head is filled with lewd fantasies, which has become mellow with a gentle smile of love and a plump body! One night, an incident happened! Ai, who had taken a bath while drinking alcohol, became hot in her bathroom. Toshiya, who puts the unconscious Ai on the bed, can't stand it and starts messing with Ai's body.
