Common camera framing
Description: The receiving partner's shoulders stay flat on the surface while the hips rotate onto one side, and the penetrating partner kneels into the twist. The torso is deliberately wrung: shoulders square to the ceiling, pelvis square to the wall.
Variations: Degree of the twist, and which side the hips fall to. Letting the shoulders follow the hips converts it into a plain side-lying position.
On camera: The wrung torso keeps the chest facing the lens while the hips present from the side, so it delivers two framings at once. That combination is why it survives in production.
AI design considerations: Deliberate counter-rotation between shoulder girdle and pelvis in the lower figure. Most renders align the two and lose the entire position.

Image to video (Thrust (deep))
long-range reciprocating motion along the body axis, full amplitude, torso following the hips, 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 the direction of the twist that defines this entry, the shoulders flat to the surface while the hips roll onto one side, and the penetrating partner kneeling into that twist. on_back and on_side are emitted together in support to carry the shoulder and hip orientations separately.
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 intermittent.
