510 Post-"I love you" Gapfiller or AU

[deviant_queen]

I know there's a 510 gapfiller in Missing Moments, but I vaguely recall reading one where Justin goes to the loft with Brian and they have sex as a way of comforting each other after the bombing.

I'm interested in any gapfiller after Brian says "I love you," as well as any fic that goes AU after that, series or standalone. Nothing super fluffy and/or OOC.
