Hideki's nephew visits the Tachibana family to celebrate Ayano and his wife's acquisition of their long-awaited home. That night, Hideki, who was supposed to stay at the house, accidentally witnessed the activities of Mr. and Mrs. Ayano. Hideki is at a loss for words when he sees Ayano's lewd appearance, which he can't imagine from the neat and clean Ayano he usually sees. The next day, Hideki, who visited the house again, witnessed Ayano, who was not satisfied with sex with her husband last night, masturbating with the receiver in one hand. Hideki can no longer control his forbidden feelings for his aunt.
