It was all Cas could do not to cry.
The warmth of it made Castiel realise how cold he'd been. How empty. It was too fast, much too fast, and he wanted to cry out when Dean broke away. If it had lasted forever it still would have been too short, left him craving more. The embrace, though short, was soft and sweet, and like nothing he had ever felt before. And they wanted more, so badly they could feel it in their bones. I burned at Castiel's soul, because they both knew this might never happen again.
