Ichika, a slightly impertinent honor student and student council president, had a habit of not telling anyone. It is to get excited by being tied up with a hemp rope. That he is a masochist who gets drunk on ropes. Even while taking classes, she looks serious, but in fact she is excited to have her body tightened with a hemp rope without wearing underwear. What triggered it was being tied up and having sex with the teacher. After that, she was trained in bondage and gradually blossomed into M sex. A lewd and masochistic bondage of the current student council president who is both intelligent and beautiful. #Yoro P
