"Mmmhmm," she answered.  He snapped the whip again, a little harder this time.  It stung a little.  He came to her, putting his hand to her throat as he had done earlier this evening, tilting her head back gently and forcing her to look at him.  "You still belong to me first, sweet," he said quietly.  She nodded, eagerly, as he walked around her again.  He smacked her ass with his open hand, and she whimpered.  She tugged at the restraints, and this time he snapped the whip at her lower back.  Hard enough to leave some faintly red marks.
