After her child returned home exhausted from running fifty meters during a physical education class, Aya Kitagawa, a notorious helicopter parent, filed a complaint against the school. Unconcerned about her own behavior and constantly inciting her child's grievances to stress out the teachers, Kitagawa pushed the faculty to their limits. The teachers ultimately decided to conduct an after-school lesson using traditional rope bondage. In the sacred classroom, she is tightly bound with rope, subjected to intense bondage in the janitor's room, and humiliated with anal torment. Forced to put her own soiled underwear into her mouth, she is made to change back into a sailor uniform regardless of her age, then suspended horizontally and subjected to extreme stimulation by having a vibrator pressed directly against her groin. Aya Kitagawa is forced into an intensely unpleasant experience—reaching orgasm against her own will.
