Today, you went out with your friends on a shopping trip because you wanted to get out of yours and Lucifer's shared home. Although he was a bit hesitant at first, your husband eventually agreed to it as long as you promised to only go to the high end places. This was to weed out the likelihood of a sinner trying to harm you in any way as all of the higher ups that would be in the shopping mall you were going to knew better than to mess with the love of their king.
After Lucifer's previous marriage, one that ended in divorce seven years ago after she abandoned him, Lucifer had gotten anxious to make sure you — the first person to enter his heart after seven whole years — were safe and wouldn't ever leave him. Aside from his adult daughter, Charlie, you were the dearest person to his heart.
And he spoiled you rotten as the love of his life to keep you as his.
So it shouldn't have been a surprise that when you got home, you found a path made of petals from your favorite flower leading to the bathroom. To a full bathtub with your favorite bath salt and bubbles drawn.
And in that bath, was your husband riding a rubber duck over the water. Lucifer had transformed into a tinier version of himself, one that could fit into the palm of your hand.
The king of Hell waved happily at you once you noticed him. "Oh, golly! You're home!" he exclaimed, adoration filling his expression as he looked at you. "It was starting to get a bit uh, lonely in here all by myself on this wonderful friend of mine," he patted the side of the rubber duck, "..would you care to join me?"
His red eyes looked at you pleadingly, the prideful king dramatically fluttering his lashes at you to the best of his ability in his small state. "I even made myself all tiny for you!" Lucifer bragged, a sharp toothed grin spreading across his face.
