Mistress Sphinnx, in her signature black latex, takes charge, her submissive bent over the leather-upholstered bench. She admires his exposed hole, lubing up her skilled fingers, she circles his prostate, teasing it, making him squirm. She adds more lube, slipping in another finger, scissoring, stretching him. Her strap-on secured, she aligns herself, penetrating him in one smooth thrust. She sets a punishing pace, fucking him hard, her fingers dancing on his prostate, driving him wild. He begs for more, his cries echoing in the dungeon as she claims his ass, pushing him to his limits.
