Under the watchful eye of their dominant mistress, a Roman slave and a visiting noblewoman engage in a heated threesome. The mistress, clad in leather and armed with a whip, commands the action. The slave kneels before the noblewoman, his face buried between her thighs, lapping at her pussy. She grinds against his tongue, her breasts heaving. The mistress joins in, her fingers plunging into the noblewoman's cunt, stretching her. The slave's cock, hard and ready, awaits its turn. The mistress orders him to fuck them both, her voice stern, as she watches, ready to punish any disobedience.
