Common camera framing
Description: The receiving partner lies on one side with the upper body rotated back toward the ceiling and one leg carried across the body, while the penetrating partner kneels into the resulting opening. The rotation runs the opposite way to the sidewinder, so the twist sits in the lower spine rather than the upper.
Variations: The crossed leg held high or dropped low, and the shoulder rotation held or released to change the depth of the wring.
On camera: The corkscrew line is unusual enough to be worth a shot in itself, but it is hard to hold and generally cut short.
AI design considerations: A side-lying figure with the pelvis rotated one way and the shoulders the other, plus a leg crossing the midline. Three rotations in one body is the hardest geometry in this batch to keep anatomically legal.

pelvis rocks forward and back through a short arc, contact never breaking, camera is locked on a tripod and does not move.
Motion only. The still you condition on must already carry the position, wardrobe and scene: restating them causes drift.
Identifiers in other vocabularies
How this position is denoted elsewhere, and what each mapping discards. Full table in the crosswalk.
twisted_torso is a bare posture tag for a torso turned to a high degree, which its wiki says artists use to show the front and the back of one figure at once, and it carries no partner, surface or penetration. It discards which way the wring runs, the pelvis on its side while the upper body rotates back toward the ceiling so the twist sits in the lower spine, together with the leg carried across the midline and the partner kneeling into the opening, so the tag cannot tell this entry from its mirror, the catalog's sidewinder. on_side and on_back in the support set carry the pelvis and the shoulders separately, crossed_legs the crossed leg and kneeling the partner.
Actions this position admits
The position fixes who is where. These are the beats that are physically possible in it, from the action catalog. Contact through the characteristic beat is maintained.
Camera moves that suit the geometry: Overhead descend, Arc (partial), Crane up, Push in.
