Bound by femdom's whims, the submissive's cock is about to face its harshest sentence yet. In a POV perspective, he watches as his mistress presents the chastity device, her voice laced with sadistic delight. She orders him to pleasure himself, her commands echoing in the silent room. As his cock hardens, she snaps the device onto him, his moans of pleasure turning to groans of frustration. She tightens the screws, sealing his fate, before leaving him alone, his cock imprisoned, his mind filled with fantasies of release that will never come.
