Intergluteal (hotdogging)

Description: An outercourse act in its own right: the penetrating partner thrusts along the prone receiving partner's gluteal cleft with no penetration at any point. The register is deliberate tease: the act frames the buttocks and the contact while withholding penetration, and in scene structure it most often serves as a build beat before penetrative positions. The receiving partner lies flat, legs together or slightly parted, while the partner rides above with the hips doing the work.

Variations: The receiving partner may stay flat or prop the hips on a pillow to lift the cleft toward camera; the act also transfers to standing, with the receiving partner bent against a counter.

On camera: Rear and overhead angles dominate because they read the cleft contact directly; side profile shows the stacked bodies but hides the defining detail.

AI design considerations: The visual evidence of the act is subtle, so tagging matters as much as geometry: render the penis resting along the cleft, not disappearing into it, since any occlusion at the midline reads as penetration.
