Nishikawa is warned by his homeroom teacher Oda for his bad attitude in class. After school, he is told to come to the staff room, but Oda-sensei is nowhere to be seen. After searching for a while, he finds the teacher in the back locker room struggling to stop his front-hook bra. Her breasts peeking out from her bra, her big tits shaking every time you try to close her hooks. When she was looking into the obscene and too stimulating scene, she was beckoned by the teacher who noticed Nishikawa, "Can you help me put the hook on?"
