In a dimly lit, cold asylum room, a defiant teen girl is led to a strange contraption, her wrists bound. The attending doctor, a stern woman with a sadistic glint, orders her to straddle the machine's phallic protrusion. The teen, defiant but curious, complies. The machine hums to life, its mechanical arm pushing a thick, lubricated dildo into the girl's virgin ass, making her gasp. The doctor watches, delighted, as the teen's body adjusts, her asshole stretching to accommodate the intruder. She's made to ride it, her tight asshole sliding up and down the silicone shaft, her moans echoing in the sterile room.
