Rin and I promised to get married once we got a job. However, Rin was assigned to the DQN class where the class collapsed. The homeroom teacher who normally supports the trainees also sexually harasses Rin. The students who were watching ignited their sexual desire, saying, "This woman is crazy." They were taken to the bathroom and overwhelmed, or they were forced to pee in the corridor. Eventually it will be used as a teaching material for sex education, and it will be vaginal cum shot to all the class in turn.
