A character gets put under hypnosis and slips into a blank, obedient trance, often shown with spiral eyes, swinging pendulums, or glowing rings and swirly background effects. The sex usually turns into mind-controlled fucking where the victim follows commands, forgets what happened, or gets “rewritten” into being eager and submissive. A lot of scenes play up the creepy contrast between a calm, dreamy face and a body getting used hard while their will is basically switched off.
