One day, she helps a male student who is being bullied on her way home from work, and learns that a senior teacher is involved in the bullying. Yuria pursues a senior teacher, but on the contrary, when her sense of justice is taken advantage of and her weakness is grasped, she is raped in front of a student who was being bullied by devouring her plump huge breasts. In addition, the senior teacher calls the students, and Yuria is circled with huge breasts and her body and her reason collapses.
