Cloistered in the closet, the siblings, chastity belts of their religious upbringing still intact, succumb to the primal urge. The brother's throbbing cock strains against his pants, a beacon of his desire. Michelle, her piety wavering, guides his thickness into her virgin opening. They move in sync, their bodies slick with sweat and lubrication, as they explore the forbidden pleasure. Their gasps and moans fill the tiny space, punctuated by the creaking of the door as they push it open wider to accommodate their lust. Their bodies slap together, their climax approaching, before they're forced to freeze, their father's footsteps echoing outside.
