...Celestia yawned, shifting in her bed, then kicked the covers off and yawned again.

“Mrfphle,” she said, regally, then took her pacifier out of her muzzle and let it dangle on her necklace.

“What should I do this morning?” she asked.

Her horn lit up, and she moved the Nightwear plush sitting on her bedside table up and down a little.

“You should show me your diaper,” she said, in a different voice, then blushed. “Okay…”

Standing up and turning away from the bedside table, Celestia undid the flaps of her onesie, and her soggy Nightwear-diaper stuck out a bit.

“Wow, you’re soggy! That’s a good princess… go and get changed,” she said, making the Nightwear plush move again, and nodded before picking up the plush, putting it on her back and waddling for the door. “Yes, Nightwear…”

Luna had got up just before her, but that wasn’t a problem, because they had a big enough changing room in their house to change both of them at once… and, of course, easily enough Nightwear diapers to supply all the changes they could ever need.

It was funny how that worked out, but Celestia didn’t notice anything strange about the idea. She simply didn’t see anything unusual about having an infinite supply of diapers, because there was nothing strange about it.

Once they were freshly changed, into puffy new diapers (one of the best kinds of diapers, along with the other kinds of diapers), both sisters took their seats at the breakfast table and began eating tasty sugary cereal.

Luna wiggled her diaper in her seat, enjoying the feeling of it and blushing a bit, then looked up at her sister.

“Did we have a plan for today?” she asked. “I don’t recall precisely.”

“Of course we have a plan,” Celestia replied. “You remember how you enjoyed our game of golf last month?”

“You don’t need to remind me,” Luna blushed, remembering how she’d grasped the idea of hitting the ball very hard a lot sooner than she’d grasped the idea of aiming.

“Well, I’ve invited some of the other Princesses out to a game of golf,” Celestia reminded her. “Gilda, Ember and Chrysalis will be there… though I think we’re going to need to loan most of them golf clubs.”

Luna frowned. “I hope at least one of them isn’t obviously much better than me.”

“That’s for us to find out, isn’t it?” Celestia asked, winking, then took another mouthful of Sugar Moons.

"Can you get them the clubs?" Luna asked her sister as they finished breakfast. "I've got to see what Nightwear wants me to do today while you do that." She giggled bashfully.

"Of course!" Celestia said. "I'll get some cupcakes while I'm out too!" she added, always having a sweet tooth.

"Good idea! Extra sweetness can't be bad for Chrysalis, it's great she's turned over a new leaf lately," Luna beamed.

"I'll be sure to get plenty of sweets and clubs!" Celestia said as she waddled out to get the clubs and sweets, diapers crinkling the whole way.

Heading to her own room, Luna waddled up to her Nightwear plush. "What should I do today? We're playing golf!" She said.

"Make sure to bring lots to drink!" Luna said in a different voice, making the plush move. "And every time you get a ball in the hole, you need to have a victory wet."

Luna blushed, giggling. "Okay! Anything else?" She asked the plush before responding to herself in a different voice, "Of course silly! You need to wear your princess plush suit!"

"Sure thing, Nightwear!" Luna beamed, waddling to her closet to get out the Luna Plush suit with a big, bulky Nightwear diaper on it, and wiggled her way into it. She then did some chores to clean the house and sort the poofy diapers into nice neat piles at the changing table, just in time for Celestia to arrive, wearing her own Celestia plush suit with thick Nightwear diaper and carrying the extra golf clubs and cupcake treats.

"Perfect timing! I just got ready." Luna beamed, both princesses waddling towards the golf course.

Nopony even gave them a second glance. After all, it was normal for princesses to waddle around in puffy pampers and plushy princess suits.

And, as far as anyone was concerned, it always had been...
