Slice of Life
Coming back to Canterlot shortly before Cadance's wedding to Shining Armor, Celestia and Cadance soon grow bored on the train ride and decide to have a bit of fun...at the expense of a sleeping Luna. Needless to say, the princess of the night is none too pleased with this development and decides to enact some revenge of her own. Hilarity ensues, and bananas may or may not be involved!
Had this idea when I first saw LoCeri's comic, and finally have some time and enough ideas to make a proper story out of it. Just a bit of random fun, not meant to be taken seriously!
Picture used with artist's permission, and seriously, if you haven't already seen his stuff, LoCeri has some awesome and hilarious comics and is definitely worthy of a follow! (Or at least a cookie)
