A femdom enthusiast, locked in chastity, is made to watch as his mistress indulges in a feast of pleasure with another. His cock throbs painfully against its cage, his balls ache with unspent seed. She mocks him, "Is this what you want? To feel my heel on your pathetic dick?" She kicks him, her sharp heel brushing against his caged cock. He moans in agony, his humiliation complete. She laughs, "Good boy. This is your punishment for daring to desire me."
