Misaki and Mana attend the same school and work at the same part-time job. One day, Misaki sees Mana's huge dick in the toilet and becomes aroused, attacking Mana. Mana, who originally had a fetish for perverted fantasies, starts to enjoy the pleasure as Misaki rapes him. Thus, the two start dating, and their perverted acts escalate to the point of fistfucking! They end up ejaculating endlessly.
