Description: A rear-entry position on all fours with one of the receiving partner's knees lifted out to the side. The asymmetry opens one hip completely while the other stays planted, which is both the mechanical point and the source of the name.

Variations: The raised leg held by the partner or held under its own power, lifted to the side or carried forward. Swapping legs mid-scene reverses the angle.

On camera: The lifted leg opens the contact point in a way that a symmetric all-fours position cannot, which is why it appears so often as a variation beat within a longer rear-entry take.

AI design considerations: An all-fours figure with one hip abducted to roughly ninety degrees and three limbs still planted. The lifted side pulls the pelvis with it, so the hips should not stay level.
