Anilingus (from behind)

Description: The receiving partner holds an all-fours posture or bends forward at the hips while the giving partner kneels close behind, face lowered to the rear. This is the standard rimming arrangement; the receiver's raised hips and sloped spine set the working height, and the giver bows into it.

Variations: The receiver can also lie flat with the hips propped on a pillow; the giver's hands spread the cheeks or brace at the hips to steady the contact.

On camera: Mostly a video beat inside a longer scene rather than a scene in itself; shot in side profile with close-up cut-ins at the contact point.

AI design considerations: A kneeling figure bowed into the raised rear of an all-fours figure. The read depends on two cues: the giver's dropped head disappearing against the receiver's hips, and face-to-hip contact with no gap. Because the giver's face is largely hidden, silhouette accuracy in the bowed neck and shoulders substitutes for facial detail; keep both figures' knees on one ground plane.
