Yui, a diligent honor student and student council president, has a sexual fetish that she can't tell anyone about. She gets excited when tied up with hemp rope. She's a masochist who gets intoxicated by rope. Even during class, she keeps a straight face and doesn't wear underwear, getting excited when she tightens her body with hemp rope. The trigger for this was when her teacher almost forcibly tied her up and had bondage sex with her. After that, she was trained in bondage and her masochistic nature blossomed. The sight of the intelligent and beautiful student council president being tied up in front of everyone and squirting is overwhelming. #YoroP
