The devil's hand creeps up on a girl who is muddied and crouching by the side of the road. When the girl wakes up, she finds herself imprisoned and tied to a bed as a lab subject by a man in a white lab coat. The man approaches the girl, licking her face, giving her a nasal enema, and giving her a hard deep throat before finally having sex with her. The man's sexual torture, called an experiment, continues, as he bandages her and ties her up with a toy to make her cum. The girl wails and falls into despair... or so you'd think, but when she is released from her restraints, she suddenly rebels against the man. Her true identity is an incredibly hardcore slut!
