The serious and excellent student, the student council president 'Yui,' had a secret fetish that she couldn't tell anyone about: getting aroused when tightly bound with hemp rope. She was a masochistic woman who got drunk on ropes. Even during class, she maintained a serious expression while not wearing underwear and tightening her body with hemp rope to get aroused. The trigger for this was being half-forcefully tied up by a teacher and subjected to bondage sex. After that, she was trained in bondage and developed her masochistic tendencies. The sight of the talented and beautiful student council president being bound and squirting in front of everyone was breathtaking. #YaoRP
