Wow this was just amazing. Funny and super hot, there were so many parts in this that were made of win:

'Finally, Dean flung his arms out and declared to the air, "I know you think I'm sexy. So come on, baby."

Sam sprawled on his bed, hunched over a National Geographic he'd swiped from the motel office. "Sometimes, you really worry me."'

For some reason, that little scene made me laugh. So adding this to my memories to re-read it later :D
