Teaching at a school in Tokyo, "Morisawa" is a popular, beautiful, and serious teacher. However, she occasionally feels uncomfortable when the male staff members give her lewd looks. One day, as she's about to borrow a book from the library before a three-day weekend, a man sneaks up behind her... The teacher, overwhelmed by humiliation and pleasure, becomes a slave to twisted desires. "Kana Morisawa" delivers a stunning performance as this perverted teacher! #YoroP
