Keep Looking For Water

Found on AO3: This is not the fic your prompt first made me envision, OP, and might not be the fic you want, but it's the fic I know how to write; there's less emphasis here on Dean's experimental period than on his relationship with Castiel. I would love to read a story that did real justice to the experimental period, and hope my fill doesn't dissuade anyone from writing it.
