Goddess Si transforms her dungeon into a birthday paradise for her cuckold, King Calvin. She presents him with a chastity cage, a symbol of his submission, before ordering him to his knees. Si, clad in a corset and stockings, sits atop his face, her heels digging into his back as she smothers him with her pussy. She then takes him to the edge, her skilled hands stroking his cock through the cage, before denying him orgasm. The session ends with Calvin, red-faced and panting, a beacon of his mistress's dominance and his own submission.
