A stern mistress presents her bound sub with a chastity device, promising pleasure only after he endures the cruelest of teases. She locks the steel cage around his rock-hard cock, then straddles him, grinding her soaking panties against his trapped manhood. The sub, helpless and humiliated, watches as she fingers her wet pussy, denying him his own release. His torment continues, a test of his commitment to her dominance.
