Breakfast in Bed
Maybe it's a first time situation, or perhaps an established relationship. A reward for a rough week or just to say 'hey, I care enough to drag my butt out of bed on a Sunday and cook for you.' Maybe your characters are home sweet home, or could be they're in mortal danger - and can only dream/discuss how sweet next Sunday's going to be once they dig their way out of this cell /net /dungeon /interstellar worm hole.
This is a prompt for all genres and ratings, really: Fluff, smut, hurt comfort, AU, canon-compliant - you decide, and give us some breakfast in bed!
