In a cramped closet, M-kun and Ayumi, haunted by religious guilt, maintain their virtue by steadying their breaths. Ayumi gently pushes M-kun's massive cock inside her, lubricated by their innate arousal. They move slowly, their tight, untouched vaginas rubbing along the hard cocks. Falling into a heated rhythm, they fuck, bodies entwined, until they collapse in post-coital remorse, their taboo lust sins staining the closet floor.
