This film depicts Sumire Kuramoto, a new teacher, being ordered around by the men in her room, obeying their orders, and getting lost in pleasure. Sumire, a very erotic and fresh type of girl, gets soaked by finger-fucking and finally comes with a crumpled-up funny face. Although the degree of devilishness is weak, we are fascinated by Sumire's dominatrix perversity. The final act is a masterpiece, in which she collapses her rationality and repeatedly arouses herself to death.
