A character’s body gets puppeted by someone else, so they move and act without being able to stop it even if they are fully aware. The sex usually turns into forced stripping, involuntary masturbation, or fucking on command, with a heavy focus on helpless poses and “my body won’t listen” panic. Artists often play it like hypnosis, remote tech, magic, or possession, and the controller makes them perform for humiliation as much as for pleasure.
