Anvil

Description: A lift defines the anvil. The penetrating partner kneels upright and raises the receiving partner's hips off the mattress and onto their thighs, so the receiving pelvis angles upward while the shoulders and head stay grounded. The legs hook over the kneeling partner's shoulders or arms, closing the structure; the receiving body becomes a ramp from grounded shoulder blades to elevated hips, with the kneeling torso as the support column.

Variations: The hips can rest on the thighs or be held in the air by a waist grip, and the legs can ride on the shoulders or in the crooks of the elbows; each choice changes the tilt.

On camera: The upright kneeling torso keeps the frame open in side profile, and a low angle reads the hip elevation directly; the pose circulates mainly in video.

AI design considerations: Anchor an upright kneeling figure, raise the partner's pelvis onto its lap, and register the ankles at its shoulder line; the grounded upper back separates this from a full fold.
