Common camera framing
Description: A face-up stack entered from beneath: the penetrating partner lies supine and the receiving partner reclines back on top of them, spine to chest, both faces turned toward the ceiling. Penetration comes from behind despite the open upward orientation, which earns the alias reverse missionary from behind. The upper body's weight rests entirely on the figure below, and motion is driven by the hips of the supporting partner.
Variations: The receiving partner's knees may bend with feet planted outside the partner's legs, adding some self-support, or the legs may extend fully along the partner's.
On camera: Overhead framing captures both faces at once, a rarity among rear-entry positions; side profile establishes the two-layer stack. Circulation is mostly illustrative.
AI design considerations: Draw two same-direction supine figures, both face-up, and give the doubled silhouette a clear vertical offset so the layers separate; without it, overhead views fuse the pair into a single body.

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.
Identifiers in other vocabularies
How this position is denoted elsewhere, and what each mapping discards. Full table in the crosswalk.
sex_from_behind encodes only rear entry and nothing about posture, so it covers doggystyle, standing doggystyle, prone bone, spooning, reverse cowgirl and, by its own closing clause, any other rear position. It discards the entire geometry of this entry: the penetrating partner supine underneath, the receiver reclined flat along their chest spine-to-chest with both faces to the ceiling, and the thrust arriving from below rather than from behind an upright back. The face-up stack survives only in the `lying_on_person` support tag, and the receiver-on-top polarity only in `girl_on_top`.
Actions this position admits
The position fixes who is where. These are the beats that are physically possible in it, from the action catalog. Contact through the characteristic beat is maintained.
Camera moves that suit the geometry: Overhead descend, Crane up, Locked off, Push in.
