The bound slave, gagged and helpless, feels the cold, unyielding floor beneath her. Her mistress, a vision of sadistic elegance, forces her onto all fours, her ass high in the air. A fake penis, slick with lube, presses against her lips, demanding entry. She struggles, but her bonds hold fast. The mistress uses her free hand to spank the slave's ass, leaving red handprints as she forces the dildo into the slave's mouth, fucking her face roughly in a degrading display of dominance.
