Celestia was standing still once more, her diaper was getting changed, again, just how often did this have to happen during the day? It was actually some time after she'd finished with court meetings for the day, Celestia hadn't wanted to bring up the subject of changing her diaper on her own, but she had hoped to be changed again right after they had finished, but no, it seemed Slushy didn't deem her diaper soiled enough for a change. Only once Celestia could have sworn she felt liquid running down her legs from her overly swollen diaper, did Slushy stop to change her again.

It was different to see, the diapers she had soiled with a more substantial 'offering' were balled up and looked like one might expect of an oversized dirty diaper, but to see one swollen with just her urine? It looked like the garment was doubled in size all around, and with her cutiemark emblazoned on the thing, it almost looked identical to some of the pillows on her bed. Celestia hadn't even been paying much attention to the world around her when all of a sudden.

"Oops, I seem to be interrupting." Twilight Sparkle was standing just a few steps away, Slushy was changing Celestia in the hallway like it was no big deal.

"I'd hardly call it interrupting, I could do her and Luna at the same time." Slushy mentioned.

Meanwhile Celestia felt her face melting, as if the power of the sun had manifested in her muzzle. Twilight was here to see this?! But once the shock wore off, Celestia realized this was perfect, she had meant to call Twilight to her at some point, and now Twilight was here!

"Twilight, I had wanted to speak to you." Celestia said, doing her best to sound as regal as ever, which was a lot more difficult when a mare was sliding a wet wipe across your nether region!

"Oh? What about?" Twilight asked, genuinely sounding quite curious, before looking over to Slushy.

"Don't look at me. This is all her." Was Slushy's only statement as she continued cleaning Celestia up.

"Well, I just wanted to ask.." Celestia found herself at a lose for words, how did she even broach this without sounding insane? "Ask why you aren't a Princess."

"Please dear, I don't need more work." An immediate response from Slushy behind the Princess.

"Right, I don't think I'd want to be in diapers Princess, or to have my magic sealed off, I know every filly wants to be a Princess when their little, usually right around the time to start being potty trained, but I've long outgrown that desire. Besides, I'm not sure my brother could handle changing three diapers whenever I go over to visit." Twilight replied, answering as though Celestia's statement were humorous. "Anyway, I was just dropping off some research notes Slushy, I'll get out of your mane and let you get back to diaper duty." Twilight said as she trotted off.

Celestia really didn't know how to process that. That entire short conversation really left her with very little to go off of, although it made her question Slushy quite a bit more.. Why was Twilight bringing Slushy research notes? Before Celestia could really process everything, Slushy was tugging her along.

"Come now Celestia, it's time for dinner with your sister!" Slushy stated excitedly, as if this was going to be 'fun' in some way.

Arriving at the room in which they would eat, Celestia came in to see Luna was already there, though before she came in the smell of something absolutely horrid smacked her in the face. It was like something had died in here, and it didn't take Celestia long to figure out what it was as she looked over towards Luna, the Princess of the night was hardly the regal figure Celestia remembered her as, even accounting for how she would always see Luna as her baby sister, she hadn't expected to actually see Luna as a 'baby' sister again, but the rather full looking diaper that was drooping off of the seat Luna was in hardly left any room to the imagination.

It seemed Luna had a handler as well, a unicorn with a pale pink coat and a mane done up in a tight bun that consisted of light pastel blue and neon yellow, her tail had the colors split evenly between it and the poor unicorn seemed to be having difficulty getting Luna to eat without food either bouncing off of her muzzle or just falling out of her telekinetic grip by being swatted by one of Luna's hooves.

"Apologies, Luna refused to let me change her until after she'd eaten." The unicorn woman spoke with a mousey voice.

"I suppose it figures, Celestia has been a delight all day, I guess it's Luna's turn to be a menace." Slushy stated as Celestia sat down and she began to feed her Princess.

Luna only seemed to smirk and giggle at being called a menace.

"Please don't encourage her." Luna's handler stated.

Celestia sat there, wondering if she should even acknowledge Luna. The Alicorn that sat across from her was not the sister she knew, and she doubted she'd get anything out of Luna other than rude sounds or bits of food. No, Celestia sat silently as Slushy fed her, she wasn't even paying attention to what she was eating, only knowing that Luna was clearly eating breakfast based on the scent of maple syrup that was blending with the scent of dirty diaper in such a way that made Celestia think she might never partake of the syrup ever again.

As such, Celestia ate as quickly as she could, wanting to get out of here as soon as possible. She didn't feel that tired, physically, but mentally? She was exhausted. Slushy seemed to pick up on it as well since she fed Celestia quite quickly and then escorted her out of the room without Celestia saying a thing to her 'sister' not that Luna engaged her in conversation either, clearly enjoying making her own handlers job difficult.

With that done, Celestia simply requested to go back to her own chamber. It would be time to move the sun soon anyway, and she was itching to be able to use her magic again, after a whole day of being without it, she would gladly move it, and the moon, several times over! Once she was back in her room, she went out to move the sun, feeling the magic flow through her horn as she connected with the celestial body, feeling a sort of normality wash over her that she hadn't felt since she'd moved the sun this morning. She briefly wondered why Luna didn't move the moon, but after seeing her sister, it was likely a good thing Luna didn't move anything.

With the sun moved, Celestia was happy to find that her diaper was not wet, or messy, it was still just clean, and Slushy had left her alone. Celestia simply threw herself onto her bed, there was no planning, not thoughts, she couldn't stand to think any more today, she just wanted to go to sleep, and wake up with things back to normal.

Only that didn't happen, she awoke, but she knew she wasn't awake, she was in a dark room, sitting on a wooden stool, no diaper, thank goodness, but there was a light bulb dangling above her, swaying slightly, with another cord connected to it, obviously the on and off cord. Before Celestia could say anything, a voice echoed all around her.

"Enjoy your vacation Princess?"

Celestia felt as though she was about to have a migraine as she heard Discord's voice all around her and then watched him materialize in front of her, before she could say anything, Discord held up a paw, but Celestia ignored it.

"You call this a vacation?!" Her anger was matched as her mane and tail briefly lit into fire in the dream-scape.

"Oh not a vacation for you no, but well, also you. Tell me Princess, are you aware of multiple realities?" Discord asked smugly.

"Yes, of course." Celestia said.

"Well, did you know that, despite their being an infinite amount of realities, there's only one of me, and I can't exist in all of them at the same time. Well, I could, but it wouldn't be quite the same. Which is to say, I sent you to a different reality, swapped you even, with another version of yourself." Discord explained.

"Why?!" Was Celestia's immediate response.

"Why because you asked me to!" And before Celestia could say that, no, she didn't ask him, he added. "The you from that reality asked me. She prayed to the god of disharmony, begged really, for something different, and I don't really blame her, you experienced her life right? You wouldn't wish that on anypony else."

Celestia hated that she agreed with him.

"I promise you nothing went off the rails, but your going to have some.. Interesting things to hear about when you wake up tomorrow." Discord said, which is when Celestia lunged off of her wooden stool, but at the same time, a disembodied claw pulled the cord on the light, and the entire dream went to black.

Celestia opened her eyes and saw her bedroom. It took a moment for her to remember the dream, she began to look around, was she really back? She sniffed the air and smelled.. Ugh.. Pee. Groaning internally, she thought Discord would have brought her back, she pulled the blankets back with her magic.

With her magic.. She was holding the blanket in her magic in front of her, her mind blanking for a moment as she tried to process what was going on, which is when she noticed the wet spot on her blanket, and then looked to see the wet spot on her bed. She'd wet the bed, or rather, she suspected the other Celestia had wet her bed.

Today was going to be a long day.

Author's Note

Kay so (queso haha), I sort of rushed this ending, originally I had envisioned a whole weekend thing, with Twilight being in charge of Celestia for a day, and Twilight just acting like everything is completely normal while Celestia tries and fails to convince her otherwise, and by the end, Celestia would have been more, beaten, in the sense that she was ready to be stuck living a life in diapers for the rest of her days, when Discord would poof her back like what happens in the end here, and then there probably would have been a short epilogue of Celestia getting the highlights of what her other self did while they were swapped.

But I just found myself unable to really stop and actually write all that, so instead I rushed the ending because if I didn't I think I was never going to actually finish this.
