Nishikawa was warned by his homeroom teacher, Oda-sensei, who had a bad class attitude. After school, I was told to come to the staff room, but ... I can't see Mr. Oda. After searching for a while, I find a teacher who is struggling to stop the front hook bra in the locker room in the back. Breasts that can be seen and hidden from the brassiere, big breasts that shake every time you try to close the hook. When I was peeking into an obscene and overly stimulating scene ... I was beckoned by a teacher who noticed Nishikawa, "Can you help me fit the hook?"
