author's summary: It's late, Arthur is drunk, and Guinevere is gone. In the cover of night, Merlin and Arthur share what can never be.
why I rec this: Scratch UST, replace it with wonderful, eternal longing. This fic might not have the usual happy they-get-together end, but, boy, I could have read so many thousand words more of them not being able to give in to their desires!
