She felt the sting of being slapped on the breast so suddenly and she growled her displeasure at him as she ripped up her insides.  The slap had made her inadvertently tighten her ass which dug his barbs into her flesh again as he pumped himself up deeper into her, but the more she took, the less pain she felt and the more heat she felt from her pussy as she started leaking down around her ass, his cock being coated with her fluid as he pulled out and pushed back in.  It wasn't much longer before she was ready to explode again, just a little tweak of her nipple or clit and she'd be screaming in ecstasy again.
