Students Tanaka and Yamada who came to the teacher's house for a study camp. I am fascinated by Maki, the teacher's wife who is beautiful and sexy. In the couple's bedroom that night, Tanaka looks into Maki's silliness as she masturbates after being rejected by her husband while asking for sex. Maki seduces Tanaka the next day and begins to play with her. I knew you were looking at me yesterday. The nature of the obscene Maki woman is exposed.
