Common camera framing
Description: Grinding replaces thrusting in this missionary refinement, usually abbreviated CAT. The penetrating partner rides high, shifting bodyweight up the receiving partner's torso until the pelvises stack in direct alignment, and motion becomes a small rocking oscillation instead of withdrawal and return. The geometry keeps continuous clitoral contact through every phase of movement, which is the technique's entire purpose: depth stays constant while pressure does the work.
Variations: The receiving partner's legs may lie together or wrap the partner's body; either way the defining elements remain the upward ride and the rocking rhythm.
On camera: This is a sex-manual staple more than a shoot staple, so its record is largely illustrative. Side profile is the informative angle, showing how far the top figure has slid toward the partner's head.
AI design considerations: Build the standard missionary stack, then translate the top figure headward so the pelvises coincide and the shoulders overshoot the partner's. Bodies stay pressed full-length; any daylight between torsos breaks the pose.

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.

- Q2044941exact
missionary covers the entire face-to-face penetrating-on-top family and discards everything that defines CAT: the penetrating partner riding high up the torso, the two pelvises stacked in direct contact, and the small rocking grind that replaces withdrawal-and-return thrusting.
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: Push in, Arc (partial), Locked off.
