Atsushi, the nephew of the Tsukikawa couple who live in Tokyo, came up to the city from his uncle's countryside home for an exam. Although the couple welcomed him kindly, Atsushi, being at a horny age, secretly borrowed his aunt's underwear and masturbated in hiding. When his aunt caught him in the act, she calmed down the flustered Atsushi and said, 'I see, Atsushi... Directly is out of the question, but if you wrap it with the underwear, then Auntie can help you...'
