A perverted man sneaks into an empty classroom at a girls' school, deeply inhaling the scent lingering on the desks and chairs, indulging in solitary pleasure. Suddenly, a schoolgirl wearing boots, YAYA, appears. He is locked inside a gym storage locker, bound all over, anally tormented, and violently dominated by YAYA's thick strapon. The eerie atmosphere and intense tension between them heighten the pleasure even further.
