Holy cow I am bad at remembering things. Sorry, mods!

First of six to be made… This will take a while. Poor Celestia is locked out the bathroom by Luna.

_“Lulu, please let me in!” Celestia whined as she gently struck the door with a hoof. On her back side was a large, fluffy, night-printed diaper. With the moons and stars, the diaper screamed that it belonged to Luna.

“Nope.” the moon princess replied from behind the door.

“I said I was sorry for taking!” Her voice more high pitched and whiny, much like a young foal’s.

“You’ve got a potty on. Use it.“

Celestia gave a soft whine as she clawed at the door.

“If it’s on, you won’t be wasting it, sister.” Luna stated very sternly, almost motherly._
