Description: A face-to-face position in which the receiving partner locks the ankles behind the penetrating partner's back and pulls, so the two pelvises stay clamped and the stroke shortens to almost nothing. The lock is the mechanism, and it converts a long stroke into sustained pressure.

Variations: Ankles crossed at the small of the back or higher between the shoulder blades; arms around the neck to add pull from above.

On camera: The clamp hides the contact point, so it reads as intensity rather than as explicit action, and productions use it for exactly that.

AI design considerations: Two stacked figures with the lower one's ankles crossed behind the upper one's back. The crossed ankles must sit behind the far body, which is the detail renders most often put in front.

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: 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 leg_lock is broader than this position: leg_lock fixes only that one partner's legs wrap another's torso; its wiki says the hold is frequently done during missionary sex, and its own examples add an upright straddle and a standing leg lock, so it covers the catalog's missionary-legs-wrapped entry as readily as this one. It discards the ankles crossed behind the penetrating partner's back on a supine face-to-face stack and the clamp that shortens the stroke to almost nothing, the mechanism that defines this entry. The wiki names pulling the partner closer only as a common purpose of the hold, not as a clamp that caps the stroke, and crossed_ankles restores the crossing but not where it sits.
