In a dimly lit dungeon, a leather-clad Domina awaits her lesbian submissive. The sub, crawling on all fours, approaches her Mistress, who presents a metal headbox cage. The sub, trained in obedience, allows her Mistress to secure the cage around her head, leaving her mouth exposed. The Domina, dominating and cruel, uses the sub's face for her pleasure, grinding her pussy against the sub's eager tongue, while the sub's muffled moans echo in the room.
