Takashi is a nephew who has just graduated from university in a new town. He went to stay with his aunt and uncle to prepare for an upcoming job interview. As a director with a lot of money, his aunt not only looks young and beautiful but also has an attractive figure. However, this comes with a downside as her body has never been satisfied in her relationship with her husband due to his erectile dysfunction. Takashi, on the other hand, has been impressed by his aunt's firm and perky breasts since their first meeting. That evening, he pretended to be his uncle and secretly entered his aunt's room, sliding under the blanket to her sensitive area, which made her so aroused that she didn't try to stop him when she realized he wasn't her husband and was about to engage in inappropriate behavior with her. After that incident, she tried to overlook it and pretend like nothing happened, but Takashi became more and more daring, always trying to seduce and arouse her to satisfy his own desires, leading her to engage in the act a second time. Their feelings became deeply intertwined from then on, and both decided to continue their illicit affair behind the backs of her husband and his uncle, even though they knew it was completely wrong.
