The sub, bound and gagged, squirms as her dominant master trails a melting ice cube along her spine. He pauses at her ass, letting the cold water drip onto her exposed pussy. She gasps, the sensation making her clench. He smirks, bringing the paddle down hard, the sound of flesh meeting leather echoing. She cries out, her body tensing as he continues, the sting intensifying her arousal. He rewards her endurance with a vibrator, her wetness coating the toy as she bucks against it, her orgasm a beautiful, brutal symphony of her surrender.
