Nishikawa, who was reprimanded by his homeroom teacher Mr. Oda for his poor attitude in class, was told to come to the staff room after school... but he couldn't find Mr. Oda anywhere. After searching for a while, he spotted the teacher struggling to fasten her front-hook bra in the locker room at the back. Breasts peeking out from the bra, large breasts swaying with each attempt to hook it closed. Nishikawa was captivated by the obscene and overly stimulating sight... When Mr. Oda noticed Nishikawa, he beckoned him over and said, "Could you help me fasten this hook?"
