Common camera framing

Side profileRearWide / full body

Description: The receiving partner lies face down with the torso on the bed and the hips out past the edge, feet toward the floor, while the penetrating partner stands behind. It is the prone counterpart of the standing edge positions and it gives the standing partner the same solid footing.

Variations: Feet on the floor or hooked back around the partner's legs, torso flat or propped on the forearms, and the hips at the edge or further out.

On camera: The change in plane at the mattress edge gives the frame a clean line and puts the action at standing height without a lift.

AI design considerations: A prone figure whose pelvis extends past a surface edge with the legs descending toward a lower plane. The edge has to be visible, since it is the only thing that explains the geometry.

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 sex_from_behind is broader than this position: sex_from_behind encodes only rear entry, and its wiki names doggystyle, standing doggystyle, prone bone, spooning and reverse cowgirl inside it and closes with any other position from behind, so it covers every rear arrangement on or off a surface. It discards the edge geometry that defines this entry: the receiver lying face down with the torso on the bed and the hips out past the edge, legs descending toward the floor, and the partner standing behind at that height. bedside restores only nearness to the edge of the bed, and no live prone tag places the hips beyond it, since prone_bone and on_stomach both want the crotch down flat on the surface, while bent_over_furniture fits only the feet-on-the-floor variation, where the receiver stands bent over the bed.
