Triple penetration (airtight)

Description: Vaginal, anal, and oral penetration held simultaneously by three partners on one receiver; genre vernacular names the state "airtight". Structurally it is the double-penetration stack with a further participant added at the mouth: the receiver rides the supine base, takes the kneeling partner behind, and turns her head to the third. Three independent rhythms must coexist on a single body, which places it at the top of the coordination scale.

Variations: Any double-penetration base can seed the arrangement; the oral partner stands or kneels at the head depending on the receiver's forward lean.

On camera: A four-body composition that demands wide framing to hold everyone, and a recognized gonzo milestone act.

AI design considerations: Four registered figures: supine base, forward-leaning rider, rear kneeler, and a standing partner at the rider's head. This is the most complex arrangement in the catalog, so verify each of the three contact points independently before judging the whole.
