Who wouldn't want to have tea with the Princess of the Sun herself, Celestia? Not Lucifer, who decides to take a break from tormenting the Earth to have a nice, relaxing chat with the alicorn ruler. And to drink tea. Though he prefers coffee. Then one thing leads to another and now he's kicking it back in Equestria, spending his vacation in the land of ponies. This will not end well.
Inspired by Regidar's story Celestia Meets God.
