Description: A rear-entry chain: the receiving partner on all fours with one partner behind, and a further partner behind them — successive same-direction links.
Variations: Partners rotating through the rear role in sequence rather than a literal chain; longer chains in group scenes.
On camera: Wide profile framing reads the repeated silhouettes.
AI design considerations: Repeated nested rear-entry geometry — each added figure copies the same offset pattern down the line.
