The femdom mistress, clad in leather and lace, commands her submissive to present his cock. He hesitates, but her stern gaze spurs him on. She produces a small, gleaming metal cage, its tiny size a stark contrast to his engorged member. With expert precision, she slides it over his length, her touch sending shivers down his spine. He gasps as she locks it, the cage now a permanent fixture, a symbol of his newfound status as her toy.
