Small and delicate, a lovely boyish beauty [Chibitori] has long suppressed his inner feminine feelings since childhood. But now, caught in the clutches of a middle-aged sadistic man, his mask of a model student is torn away as his sensitive body evolves into that of a perverted little demon. Subjected to one extreme training after another—cosplay pet play, humiliating diaper scenes, saliva-swapping kisses, forced orgasms through bondage, and anal sex—he lets out deeply masochistic cries, yet his cock only grows harder with each torment.
