In a dungeon of shadows and chains, a master's command echoes, "Kneel, dog." The servant's body trembles as he's bound in intricate, cruel ropes, every muscle taut, skin glistening with sweat. The master's crop flicks against his nipples, his ass, leaving red welts that pulse with heat. He's made to lick the master's boots, then her pussy, her clit, until she comes with a growl. Finally, she attaches a spreader bar to his legs, leaving him wide open, completely at her mercy. She fucks him hard, using him for her pleasure, until he collapses, spent and marked, a true servant of her desires.
