Mistress Kara, a fetish goddess, ties her submissive to a chair, his arms and legs spread wide, his body trembling in anticipation. She teases him with a strapon, rubbing it against his mouth and cock, before moving to the Sybian. She turns it on, the dildo vibrating and thrusting. She forces her slave to mount it, his asshole stretching to accommodate the massive toy. Kara watches, her eyes gleaming with sadistic pleasure, as he's brought to the brink of orgasm, only to be denied. She slaps his face, laughs, and increases the Sybian's power, intent on driving him to the edge of madness.
