Cheating the Cycle of Life- A Padded Pony Collab

For Princess Luna, being banished to the moon for 1,000 years was one of the worst things that had ever happened to her in her entire life. And that was saying alot considering how long she had been around.

There were a lot of reasons why Luna hated being banished to the moon. The most obvious was that she had no friends, and nopony to talk to but her own shadow, which did nothing to help her feelings of insecurity.

But what really made being banished to the moon for such a long period of time so horrible, was what happened to Luna’s body when she finally returned to Equestria.

“Why must we wear these hideous under garments? We are not some little foal that needs adult supervision!” Princess Luna complained, as she currently lay upon the padded surface of the changing table in her bedroom. Her wet and messy diaper squishing uncomfortably against her rump, as she waited for her big sister to change her.

It turned out, that being stuck on the moon for so long had caused Luna’s body to adjust to the lower gravity there. And when she returned after 1,000 years, the change in gravity from the moon to Equestria resulted in parts of Luna’s body no longer working properly. One of them, was her ability to control her bodily functions, much to the Princess of the Night’s embarrassment and displeasure.

“Luna, we’ve been over this a hundred times already,” Princess Celestia said with a sigh, as she used her magic to pull down her little sister’s used diaper. It had been a long time since she’d had to do this, but she just didn’t feel like trusting the care of Luna to the royal guards. She knew how much they liked to trade secrets about the princess, including Celestia’s not so secret love, or rather, addiction for cake “You need to wear these, so you don’t have an accident in front of our subjects. Until your body fully readjusts to Equestria’s gravity, you need protection.”

“We do not need protection, we are the Princess of the Night!” Princess Luna bellowed in her royal Canterlot voice “We have no such problem, we just need to make some adjustments to our lifestyle, that is all!”

“You say that, but you and I both know the truth,” Princess Celestia sighed again, as she tossed the used diaper into a diaper pail, and retrieved some wet wipes and foal powder “Now, hold still. I don’t need you to get a rash.”

“Sister, we can change ourselves! We do not require your services!” Luna shouted defiantly “Stop treating us like we’re still a little foal!”

Princess Celestia couldn’t help but chuckle “Considering the way you reacted to our subjects not appreciating your night, I would say you’re already quite like a foal. You didn’t have to throw a temper tantrum and threaten to plunge Equestria into eternal night just to make a point.”

“We told you already, sister, it was not our doing,” Princess Luna protested, as she wiped and powdered “It was those vile nightmare creatures. They lied to us, promising us respect and love.”

“And yet you chose to believe them,” Princess Celestia said with a shake of her head “You have no idea how much it tortured me to have to banish my own sister.In my years of reign, a number of them were done in a....less than mentally healthy state.”

Princess Luna was surprised “Sister, we had no idea thou were in such great pain. When the creatures of nightmares showed us the world of Equestria, it seemed like you and everyone else had forgotten and moved on. We did not want to believe we were forgotten so easily, yet it seemed like such was the case. Why did thee see fit to not tell us when we first returned?”

“I tried to reason with you, Luna, but you were not in control,” Princess Celestia said seriously “A fact I kind of clued into when Nightmare Moon had to take a bathroom break after defeating me. I suspected it was you fighting against her influence, in more one ways than one it would seem.”

“Arst thou trying to imply that Nightmare Moon took away our self control as a punishment for not helping her?!” Princess Luna asked furiously “Because if so, should we ever meet Nightmare Moon again, she shall endure a pain far worse than anything seen in even the gates of Tartarus!”

“It was just a joke, Luna,” Princess Celestia chuckled “You really should lighten up and look on the bright side.”

“And what would that ‘bright side’ be oh dear sister?” Princess Luna asked sarcastically, as a new diaper was taped to her rump.

“There are many children in Equestria who have a problem similar to what you’re going through now,” Princess Celestia explained “If you were to model for one of the diaper companies, it could go a long way towards improving your image. Who knows, they might even name a brand of their products after you.”

“Model for a diaper company, arst thou insane?!” Princess Luna bellowed at the top of her lungs “Such a move would make us the laughing stock of our royal subjects for decades, perhaps even generations. And all because we were stuck on the moon for 1,000 years!”

“It was just a suggestion, Luna, you don’t have to take it,” Princess Celestia said calmly, as Princess Luna climbed down from her changing table “Though I think you’d look pretty cute. It’s your decision whether or not you want to take up the offer, but I think if you supported them, they’d be willing to help you with your problem. I can’t keep buying diapers for you without the general public becoming suspicious of something. But for right now, I need to dispose of your dirty diapers, before they stink up this castle.”

“We do not stink! It is you who stinks!” Princess Luna complained, pouting, even though she knew that was a lie.

“Luna, if you’re going to keep acting like a foal all the time, then you’re going to end up getting treated like one,” Princess Celestia threatened “And believe me, sister, I rarely  lie.”

Luna gulped, feeling a few droplets dampen her new diaper.
