Common camera framing

Side profileOverhead

Description: The complete fold is the pose: the receiving partner draws both legs back until the ankles cross behind their own head, self-locked, rotating the pelvis fully upward while the penetrating partner presses down over the top. This is an extreme-flexibility named position; the receiving spine rounds completely and the body compresses to roughly half its supine length, so the penetrating plank meets a compact, tilted target rather than a long one.

Variations: The legs can be pinned by the penetrating partner instead of self-locked behind the head, and the depth of the fold scales with the receiving partner's flexibility.

On camera: Rare outside flexibility-showcase scenes, it survives mostly in illustration. Overhead framing reads the fold best; side profile confirms the pelvic rotation.

AI design considerations: Place the receiving figure's crossed ankles beside the head, an arrangement that inverts normal limb logic, and verify every joint chain, since generators readily produce anatomically impossible legs here. The top figure's plank should clear the fold, not flatten it.

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.

Expected figure count: 2. Global pose conditioning does not make a diffusion model count bodies. Count figures and limbs at full size before judging quality, because thumbnails hide the failure. The tag legs_over_head is broader than this position: legs_over_head is a bare flexibility posture carrying no partner and no penetration - it is used for solo folds and non-sexual contortion - so it drops the ankles crossing behind the receiver's own head, the self-lock, and the penetrating partner pressing down from above face-to-face.
