The mistress, a vision of dominance, commands her sub to assume the position. He obeys, his body trembling with anticipation. She runs her fingers over his naked flesh, igniting goosebumps. She picks up a wicked-looking chastity device, her eyes gleaming with mischief. She fits it onto him, her touch gentle yet firm, before locking it in place. His cock twitches, eager for release, but the device holds it captive. She smiles, her voice a purr, "You're mine now, to use as I please." She picks up a remote control, pressing a button that sends a jolt of pleasure through him, only to cut off just as suddenly, leaving him yearning for more.
