A dominant woman, clad in leather and lace, commands her submissive to kneel before her. She grabs his chin, tilting his head up, and sneers, "You've been a bad boy, haven't you?" He nods, eyes downcast. She smirks, "Then you know what's coming." She takes hold of his testicles, her grip firm yet careful, not to damage but to control. She begins to squeeze, slowly at first, then harder, relishing his groans of pain. She alternates between gentle caresses and harsh squeezes, maintaining her power over him, his pleasure and pain entirely at her mercy.
