Bound and under her mistress's thrall, a submissive kneels, his eyes fixed on the floor. She towers over him, her naked form slick with sweat and cum. She's been riding him, using him for her pleasure, and now she wants to make him taste her reward. She straddles his face, grinding her cum-soaked pussy onto his mouth. He obeys, lapping at her, cleaning her, his tongue coated in their mixed juices. She moans, her body shuddering with pleasure, as he worships her, his own desire forgotten in her service.
