Common camera framing

Side profileWide / full body

Description: The receiving partner lies at the edge of a bed or table with legs raised while the penetrating partner stands between them. The height offset gives a standing partner full range of motion.

Variations: Ankles on the standing partner's shoulders or held wide; hips lifted by a grip at the waist.

On camera: A production favourite — the standing partner leaves the sight-line to the contact point clear in side profile.

AI design considerations: A supine figure on a raised plane with a standing figure at its hips; the surface height difference is essential to the read.

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 records only that the receiver lies on their back and the partners face each other. It discards the edge-of-surface geometry that defines this entry, hips at the very edge of a bed or table so the pelvis clears the mattress, and the resulting height offset that lets the penetrating partner work standing rather than kneeling. the permitted vocabulary has no edge-of-bed, bed-edge or furniture-edge tag (verified absent; on_table is present but denotes being on a table, not at its edge), so support can only assert that one partner stands while the other is on a bed, never that the two meet at its edge.
