EroKas! ~The Class Rep’s Secret Fetish~

Synopsis

The protagonist sets his sights on Yoshino Keiko. After discovering she’s been bringing erotic doujinshi to school, he uses this secret along with her feelings for him to seduce her. While pretending to be her boyfriend, he exploits her passive nature and has his way with her. But Keiko proves far more lustful than he imagined and seems quite willing.

The protagonist’s original plan was to slowly make her obedient through their fake relationship, but seeing her true perverted nature, he realizes there’s no need for such careful conditioning. When he learns that Keiko harbors exhibitionist and non-consensual fantasies, he brings her to a crowded train to fulfill her desires and reveal her true self. He declares she will become his sex slave, promising to fulfill all her perverted wishes.

Though naturally serious-minded, Keiko is shy about embracing her role as his sex slave. To free her from these inhibitions, the protagonist brings her and her friends to situations where they can fully express their desires as women—being used by students and having sex with older men in public. Through these experiences, Keiko learns to accept her perverted nature.

Grateful to the protagonist for giving her this freedom, she confesses her desire to become his personal pleasure toy. And so, Keiko begins her happy new life as a woman.
