Iyo, a married teacher, transfers to the same school as her husband in the spring. Work and home life remain peaceful until her husband witnesses Takahashi, the school’s worst delinquent in this adult role-play, bullying someone. A fierce argument ends with her husband shoving him and injuring his finger. When Iyo apologizes desperately on her husband’s behalf, Takahashi demands that she prove her sincerity by showing him her breasts. Telling herself it is the only way to protect her husband, she undresses and exposes herself—but his demands do not stop there.
