Mei, a model honor student and student council president, has a sexual fetish that she cannot tell anyone about. It's the excitement of being tied up with hemp rope. That he is a masochist who gets addicted to ropes. Although she usually has a serious face, she is excited to have her body wrapped in hemp rope without wearing any underwear. The trigger was that the teacher tied her up semi-forcibly and had sex with her. After that, she was trained in bondage and gradually developed her masochistic nature. The talented and busty student council president falls into the swamp of lewd and masochistic bondage. # Yoro P
