Common camera framing
Description: Both partners recline back on their hands facing each other, hips pressed together with legs interleaved past each other's torsos — bodies forming an X in profile.
Variations: One partner more upright than the other; rocking rather than thrusting drives the motion.
On camera: The mutual recline reads in profile; more common in position guides than in shoots because faces sit far apart.
AI design considerations: Two reclined seated figures joined at the pelvis with interleaved legs — the mirrored back-lean is the signature geometry.
