Why This Must Be Read: Absolutely, hands-down, the best Glee fic I've ever read. This takes the 'two characters are forced to share a bed and end up having sex' trope and does it better than I've ever seen it done before. It was written anonymously for the Glee kink meme, but it's 10,000+ words long and is absolutely worth setting aside some time for. The author writes these characters so skillfully and the whole thing is just incredibly absorbing.
