"I'm sick of cleaning up your mess," the mistress snarls, pushing her slave to his knees. His cock twitches in its cage, eager for touch. She strokes him through the bars, her pace steady, her gaze intense. "You think you can just rub one out whenever you want?" She spits, increasing her speed. His breath hitches, his body tensing, but she stops abruptly, leaving him panting and desperate. "Not today, pet. Today, you learn patience." She smirks, holding his gaze as she denies him again and again, his humiliation her pleasure.
