Married for 15 years, the relationship between the husband and wife Uno has gradually cooled off, no longer having sex with each other for a long time. At this time, Uno's nephew, Yuki, came to Tokyo to prepare for the university entrance exam and wanted to stay at his aunt's house for a few days. It has been a long time since they last met, and now he has grown up and become extremely handsome. Determined to pass this year, Yuki has been holding back and refraining from masturbating for a whole year. But his determination quickly crumbled when he saw the seductive body of his aunt. Uno's image kept appearing in his mind, his penis always getting hard, making it impossible for him to focus on studying. Uno accidentally caught Yuki masturbating, so Yuki had to be honest with her and asked her to help him masturbate. Out of love for her nephew and wanting to help Yuki focus on studying, Uno agreed. She used her hand to help him ejaculate, but as soon as it was done, Yuki's penis got hard again. Especially when he saw Uno doing yoga, he couldn't take it anymore and rushed to satisfy his sexual desire! Due to not having sex for a long time, Uno was extremely sensitive. Every thrust from Yuki made her body tremble, constantly moaning in pleasure. And during Yuki's stay, he repeatedly had sex with his seductive aunt, releasing all the stored-up sperm he had restrained and accumulated for a whole year inside Uno!
