Natsumi, a former female teacher, gives yoga lessons to her student, Akira. Akira indulges in masturbation and delusions of sluts irresistibly to Natsumi's ripe plump body. Natsumi is also stimulated by Akira's young body and writhing in a violent 3P delusion. One night, when Akira confesses his feelings to her, Natsumi pushes up her hips and asks for a bag, even though she refuses, and ends up lividly.
