Teacher Kuroe Fujisaki has always maintained strict discipline over her students, but she harbors an unexpected secret. She has been blackmailed by one of her students who discovered her weakness, forcing her to obey his every command. During class, she was provoked into humiliation and even photographed in compromising situations. Furthermore, she was drugged into unconsciousness and repeatedly summoned to the equipment room while defenseless, compelled to follow the students' orders. These acts included sucking a student's cock, being stimulated with a vibrator, being made to cum, and having a cock inserted into her. However, this secret was eventually uncovered by other teachers, leading to a new kind of party with the students beginning anew.
