Masturbation (supine)

Description: The default solo scene position: the performer lies supine, knees drawn up, one hand working between the thighs while the body rocks with the motion. Unlike the static display poses this one is built around continuous action, and the hand is the narrative center of the frame.

Variations: The legs raised toward vertical or spread wide; a toy substituted for the hand; the free hand brought to the chest.

On camera: Covered from the foot of the bed, at a low angle, or in profile, with close-up inserts on the hand; penetrating-style POV framing is also conventional.

AI design considerations: A supine figure with the knees up and one wrist registered at the pelvis. Hand placement is the focal detail, so finger articulation and wrist angle must survive close-up scale, with manual insertion occluded plausibly by the thighs.
