MKON-006 Classroom Collapse: The girl aspiring to be a teacher was taken by DQNs during her teaching practicum and used as sex education material in the class.

Rin and I promised to get married if we both got a job. However, the place where Rin was assigned for teaching practice was the DQN class, which had collapsed. The homeroom teacher who normally supports the trainees also ends up sexually harassing Rin. The students who were watching ignited her sexual desire, saying, "This woman is going to fuck me." She is eventually used as a teaching material for sex education, and is vaginal cum shot by the whole class in turn.
