I occasionally see references to fanfiction, that curious do-it-yourself genre. "Fans" write their own takes on favorite characters, usually from TV shows. It IS a world of its own, evidently, and I always figure there's so much ELSE to turn me on.
BUT some of it is wonderful, sexy and amusing. Anyway, I just discovered there's a whole sub-genre to the obviously popular "House" fanfic -- namely, imagining Cuddy and "Thirteen" (the amazingly hot Olivia de Wilde) fucking. Well, certainly, I'd like to be there for that scene -- maybe even make it a threesome!
So, anyhow, pretty much by chance, I found an LJ person who writes in that sub-sub-category, and she's pretty artful about it. Have a read --
