In a sleek, high-end dungeon, a domme initiates her sub into the world of cuckolding, pushing his boundaries and desires. She brings in a handsome, well-endowed stranger, making her sub watch as she bossily orders the man to strip. He complies, revealing a stiff, eager cock. She commands her sub to worship it, making him lick and suck, before turning to the stranger. "Fuck my mouth," she demands, opening wide. He obliges, thrusting deep into her throat, while her sub looks on, humiliation and envy etched on his face, yet helplessly aroused.
