In a dimly lit dungeon, Mistress, clad in leather and latex, commands her submissive slave to present his cock and balls. She teases him with a cruel smile, running a sharp nail along his shaft. The slave's breathing deepens as she slips on a gloved hand and begins a ruthless fisting, her wrist disappearing into his eager gash. Mistress' other hand is busy tormenting his balls, rolling and tugging them with precision.
