In a dimly lit dungeon, a stern mistress commands her new slave to kneel before her. She forces his head down, grinding her heel into his balls, a sadistic smile playing on her lips. The slave whimpers, but she silences him with a sharp slap. She sits, pulling his head into her lap, her fingers dancing cruelly over his most sensitive area, causing him to squirm. Her laughter echoes as she uses his balls as stress toys, squeezing and twisting until he's a panting, begging mess. She relishes her power, her eyes gleaming with dark satisfaction.
