Caitlin had never had sex like this before. Yes, the four of them experimented at times but it was nothing like this. She wanted Carson to push into her as hard as he could, even if it might hurt her. And with each thrust, Caitlin felt herself getting close to falling over the edge. But she wanted to hang on for a bit longer. She wanted to come with Carson as she pierced his skin with her fangs.
She gasped when his fingers started to rub her clit. Caitlin pressed down harder, her body covered in a sheen of sweat. It was hard to keep control anymore. She could sense Carson was close - she could smell it, too. Her fangs slid down again and just as Carson started to warn her, she dipped her head down and bit into the top of his shoulder.
The bite sent waves of pleasure through her and that, coupled with everything Carson was feeling, pushed her over the edge. Caitlin let out a muffled cry, her fangs still in Carson, as she came hard around his cock. She pulled her head up and slowly licked the bite, her body still trembling.
After several moments, she looked at Carson. "Are you all right?" she asked, hoping she hadn't hurt him.
