In a dimly lit room, a dominant woman sits, her eyes gleaming with anticipation. Her submissive kneels before her, a chastity device firmly in place. She runs her fingers through his hair, a cruel smile playing on her lips. "You've been a good boy, waiting so patiently," she purrs, "But now, it's time for your reward." She reaches into her lap, pulling out a small key. With deliberate slowness, she unlocks the device, freeing his throbbing cock. "You may touch yourself," she commands, "But do not come until I tell you to." He obeys, his hand moving tentatively at first, then with increasing urgency. She watches, her own arousal evident, until finally, she grants him release, his body convulsing as he spills onto the floor.
