English Erocas! -Gakkyuuiin no Kakureta Seiheki | エロキャス！ ～学級委員の隠れた性癖～

The protagonist decides to target Nagasawa Karen. By chance, he learns that Karen has been bringing erotic doujinshi to the school and uses that and her fondness for him to have sex with her. The main character takes advantage of Karen's weak pushiness and fucks her as much as he wants, while pretending to be her lover. However, Karen was more erotic than the protagonist had imagined and did not seem to fully satisfied her. The original plan was to pretend to be a lover and gradually subdue Karen. Looking at her skankiness, I feel that there is no need to corrupt her so carefully.

Just then, the protagonist discovers that Karen originally had a desire to be molested. We call her to the molestation train to expose her true nature in a single step and fulfill her desires. The protagonist also reveals his true nature and tells her to become his own sex slave. He said, "Become my own female and I will fulfill all your dirty desires"

Karen, who is serious at heart, longs to be a sex slave, but remains shy. In order to remove the fetters from Karen's mind, Machiko and Haruka take her to a place where she can expose herself as a female respectively. Through being a student's meatbag and getting fucked on the street by her daddies, Karen has learned to forgive herself for being a dirty girl. She thanks the hero for doing such a thing for her and confesses that she wants him to be her masturbator. She then went on to live a happy life as a female.
