"I got you a present," she purrs, holding up the metal cage. His eyes widen in anticipation, then despair as he realizes its purpose. She makes him strip, his cock already hard and eager, then forces the cage onto him, locking it with a mocking laugh. She spends the day parading around in revealing outfits, rubbing her pussy in front of him, making him taste her juices, all while denying him the relief he craves. His cock strains against the cage, but she holds the key, and the power, leaving him in a state of constant, frustrating arousal.
