Common camera framing

Side profileWide / full bodyRear

Description: A bank of cushions is built into a slope and the receiving partner kneels forward over it with the chest supported, while the penetrating partner kneels behind and leans back onto their own heels. Both partners are supported, which is the point: it is a position built to be held for a long time.

Variations: Height of the bank sets the angle, and the rear partner can sit fully back on the heels or rise up to change depth.

On camera: The cushion bank is awkward set dressing and reads as domestic rather than staged, so this appears far more in illustration than in production.

AI design considerations: Two figures both supported at an angle by a wedge of soft mass between them. The prop is structural here rather than decorative, and omitting it leaves the pair floating.

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 covers every rear-entry arrangement, and its wiki names doggystyle, standing doggystyle, prone bone, spooning and reverse cowgirl inside it. It discards the cushion bank built into a slope that carries the receiver's chest, the receiver kneeling forward onto that slope, and the penetrating partner kneeling behind and settled back onto the heels, so that both bodies are supported for a long hold. doggystyle was passed over because its wiki rules it out unless the receiver is on all fours or close to it, and here the chest rests on the bank rather than on the hands.
