In the dimly lit dungeon, Mistress commands her trembling slave to stand before her. She admires his quivering body, his cock already hard, knowing it will be the last time he experiences such freedom. With a wicked grin, she produces a gleaming chastity cage, cold and unyielding. She expertly secures it around his desperate cock, locking it with a resounding click. 'You will never cum again without my permission,' she purrs, her eyes sparkling with sadistic pleasure. The slave, now truly hers, is sent to his room, his new life of enforced chastity and humiliation beginning.
