a girl, 18 years old, young face, full body visible, She kneels on a foam mat in isolation, wearing only a thin latex harness and four active sensors at her hips and thighs. A small control pad is buckled around her neck, delivering vibratory corrections for posture, eye contact, and hand position. A chrome insert beneath her twitches silently. Her wrists are folded neatly in her lap. One false move triggers a full-body pulse.
