After a spring transfer, married teacher Iyo begins working at the same school as her husband. Their careers and home life are going smoothly until her husband catches Takahashi, the school’s worst delinquent adult student in this school role-play, bullying someone. A heated argument ends with her husband shoving Takahashi and injuring his finger. When Iyo apologizes profusely on her husband’s behalf, Takahashi demands that she show him her breasts to prove her sincerity. Telling herself she has to protect her husband, she undresses and bares her breasts—but his demands do not end there.
