Teacher Waka is reduced to the role of a submissive pet, completely at the mercy of her students, enduring forced sexual acts between classes. Before lessons begin, she is compelled to perform oral sex, and during exams, she's dressed in lewd outfits and secretly tormented with a vibrator. Her big breasts are constantly groped, and her body is repeatedly abused. Even the student council president scolds her for her indecent attire before forcefully taking her. Further tormented by verbal abuse and consumed with jealousy, she is repeatedly raped by her "master," the student. Crushed both physically and mentally, she is forced to endure it all without resistance.
