In a dimly lit, private dungeon, a muscle-bound man, arms bound behind him, awaits his Mistress's pleasure. She, clad in leather, teases him with a belt, running it over his quivering body. She commands him to kneel, his eyes locked onto her heels. She unbuckles the belt, doubling it, and brings it down on his ass, leaving red welts. She orders him to lick her boots, her cunt, her fingers, he complies eagerly. Then, she lubes up the belt, pushing it into his ass, fucking him with it, as he groans in pleasure and pain, his cock throbbing.
