"Why do you watch anime all the time, even at school? Is that fun?" Seiichi Kushikawa was an ordinary student. When Rio Saeki, a popular girl in his class, and popularly known as a slut, suddenly started chatting to him, it was the spark that led to an unexpected and lurid affair.

"Hey Kushi. Wanna do it with me?" True to the rumors Rio was a loose and eager slut. The unexpected part was that she was faking her sluttiness. In fact, Seiichi almost had more experience.

Seiichi found himself taking the initiative. He would mold Rio to suit his fetishes. His wants would be her wants. The idea was to turn her into his personal fuck object. And he in turn would become hers.
