Mirrors Don't Tell Lies

Dean and Castiel share a similar problem. They cannot see their own reflections in a mirror. This is caused by them both having a certain... vampiric condition. *This is as fluffy as they come. Some nice, high school/monster AU with K plus for one minor swear and sweet boy kissing. I have to write something happy now because I know that after the season premier, I won't be able to.
