Common camera framing

Side profileLow angleClose-up

Description: Both of the receiving partner's legs are contracted and held tight against the stomach while the penetrating partner kneels into the resulting gap. The classical name comes from the folded limb shape rather than any movement.

Variations: Knees held wide or squeezed together, the penetrating partner taking the ankles in one hand, or the receiving partner clasping behind the knees to hold the fold without help.

On camera: A deep-angle position that reads best low and close. The folded body compresses into a small area of frame, so wide shots waste most of the picture.

AI design considerations: Extreme hip and knee flexion with the thighs pinned to the torso. The pelvis rotates up, and the lower spine should curve rather than stay flat against the surface.

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 missionary is broader than this position: missionary fixes only that the receiver lies on the back facing the partner, with a folded body named as one option among several, so it holds equally for flat, leg-locked and folded forms. It discards the defining fold, both legs contracted tight against the stomach with the pelvis rotated up, and the partner kneeling into the gap rather than lying over.

    Attested source name. Both legs contracted and held against the stomach. Burton fixes only the legs, so the kneeling partner is the catalog's staging.
