Evil Wrapped in a Fangirl Disguise

I think this is the first smutty fic that I've read, where Dean and Castiel are, well, Dean and Castiel. I've seen so many stories where you can just replace the names, pronouns, and features, and it is pretty much the same thing, but this is the exact opposite from that. This is absolutely perfect. I especially like "my angel can go 0 to 60 in no seconds flat, how about yours?" That should be on a t-shirt! :D
