Sixty-eight (68)

Description: One partner lies face-up along the body of the partner beneath, head-to-toe, so the lower partner can reach the genitals above their face while the top partner simply receives. The stack runs back-to-front rather than front-to-front, making it the one-way counterpart of the mutual 69; the numeral name records the top figure facing up instead of down.

Variations: The top partner may arch the back to adjust contact or lie flat along the supporting body; because the lower partner bears the full weight, it is usually held briefly as a novelty rather than sustained.

On camera: A guide-book curiosity more than a shooting standard, appearing occasionally as a transition beat within a scene; side profile is the framing that separates the two stacked bodies.

AI design considerations: Compose two supine figures stacked head-to-toe with both faces turned upward; the top figure's upward orientation is the identifying cue and must not flip into a prone fold. Expect heavy torso-on-torso occlusion; keep the lower face registered beneath the upper pelvis and offset the top body slightly so the stack reads.
