Common camera framing
Description: Both partners lie on their backs facing away from each other with the legs scissored at the hips, so from above the pair form a clean X with the heads at opposite corners. Neither partner supports the other and the movement comes entirely from the hips.
Variations: The crossing angle can be opened or closed, and either partner can prop up on the elbows to see the other.
On camera: A purely overhead position. From the side it is unreadable, and that limitation is why it appears far more in diagrams than in video.
AI design considerations: Two supine figures with heads at opposite ends and legs interleaved at the pelvis. The X should be obvious from above, which means the torsos need a wide angle between them, not a narrow one.

Image to video (Grind (rocking))
pelvis rocks forward and back through a short arc, contact never breaking, 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.

- on_backbroader
on_back is a bare posture tag, lying on one's own back, that carries no partner and no sex act, so it holds for any supine figure in any context. It discards the whole X: two supine partners with heads at opposite corners, legs scissored at the hips, and neither body supporting the other. The scissor tag cannot stand in, because scissoring is an active alias of tribadism, whose wiki limits it to female-to-female genital sex while this entry is MF, so only interlocked_legs and leg_between_thighs in the support set carry the leg weave.
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.
