Heaven and Hell Be Damned
Castiel had done a lot of bad things in his day but of everything he had ever done, down to rebelling against heaven and God, this had to be the worst of it. Guilt ripped through him in a massive wave and Castiel's muscles clenched. He had not imagined his first time touching Dean would have ever played out the way it did, but it had happened and that was that. He had shamelessly pleasured Dean as he was restrained and flicking back and forth between demon and normal Dean. It had been surreal. The worst part about it though, was that there was truth to everything Dean said, even as his eyes flickered black. Demon Dean had known what real Dean wanted and had even gone as far to allow Castiel to see the real Dean in between pleasure wracked sobs. Real Dean had begged and looked like he wanted it too.....so why was Castiel feeling so guilty?
