Common camera framing

Side profileOverheadRear

Description: The receiving partner lies face down over a supine partner while a third works from above and behind, so both entries come from the rear rather than one from each side. It is the flattest of the double arrangements and the only one where all three spines run roughly parallel.

Variations: Hips propped on a cushion to open the upper angle, the base partner's legs spread for bracing, and the top partner kneeling astride rather than in a full plank.

On camera: Profile only. The three parallel bodies read as one mass from above and the arrangement disappears entirely from behind.

AI design considerations: Three horizontally stacked figures with parallel spines and staggered shoulders. Without the stagger the silhouettes merge into a single indistinct block.

Image to video (Thrust (shallow))

short-range reciprocating motion along the body axis, small amplitude, hips leading, 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: 3. 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 double_penetration is broader than this position: double_penetration records only the two simultaneous penetrations and carries no posture, so it covers this entry and the catalog's sandwich-dp, which the seed builds from the same three base postures, on identical terms. It discards the flat prone build that the record names: the receiver face down along a supine partner with the third partner above and behind, all three spines roughly parallel. prone_bone in the support set restores the face-down rear entry, but no live tag separates this record from sandwich-dp.
