A 20-year-old female college student from strict parents leads a strict ballet life every day. Before she knew it, she had become an excellent ballerina and grown into a person who everyone around her had high expectations of. She was happy that people had high expectations of her... but it also brought her pain. She had always had a strong sex drive and would secretly masturbate at home so her parents would never find out. She was perverted. One day, driven crazy by the rigorous daily ballet lessons, she secretly met an older man on a dating app and asked for bondage training. When ballerinas become excellent, they also become perverts.
