After leaving her teaching job following marriage, Misuzu now works as a private tutor. She struggles with a disinterested ronin student who lacks motivation. One day, she jokingly suggests, "If you score well on the practice exam, you can do whatever you want with my body." Inspired by her words, the student's grades rapidly improve, eventually leading to situations where she spreads her legs in a vulgar M-shape, showing off her sexy pantyhose-clad legs.
