Newly appointed female teacher Sakura, aware of her own dark desires, secretly engaged in sexual teasing with her male students. Whenever her arousal made it impossible to focus on teaching, she would quietly give them blowjobs, convincing both herself and the students that it was a harmless way to relieve tension. However, her actions were discovered by the vice principal, who had long harbored feelings for her. Using this secret against her, he blackmailed Sakura into becoming his sex slave, forcing her down a path of submission and depravity.
