Minako, a mathematics teacher, is extremely popular with the male students on campus. On the other hand, in her private life, perhaps because she was not blessed with children, there was a misunderstanding with her husband, and she led an unsatisfactory sex life. At that time, "a certain rumor" begins to be whispered in the school. It is Minako who has an abnormal admiration for "older women", skillfully guiding her students to secretly have physical relationships, and having sex with a young man. It was a thing that eliminates daily dissatisfaction.
