[Kaitou Yuuhi] 24H Kyouiku Shidou (Otokonoko Heaven's Door 4) [mysterymeat3]

After clumsy little Aoi shatters the principal's prized vase, the bespectacled old man decides the boy will pay with his body, coaxing him into anal fingering that leaves the petite shota moaning, hard, and shamefully tingly. Punishment snowballs into daily after-school 'teaching,' the principal's thick cock outclassing the toys Aoi already knows too well as he learns to love every twitching inch inside him. Weeks later Aoi returns on his own, nipples pierced and squeezed into frilly lingerie, a fully feminized pet whose masochistic girly ass now belongs to his kind instructor.
