In a voyeuristic POV, a femdom enthusiast teases her submissive with his new chastity device. She runs her tongue along the edge, her breath hot on his trapped cock, before locking it in place. She guides him to stroke himself, his movements restricted by the device, drawing out his pleasure. She whispers dirty promises of future release, her voice laced with power and control, as he groans in eager anticipation of his eventual, explosive orgasm.
