Potty Training Tales

Princesses in Potty Training (Royal Sisters)

It had only been a week since the princesses of Equestria had returned to being toddlers after Discord’s curse. Unfortunately that meant they had to undergo potty training for the first time in over a thousand years, which was most humiliating to both of the royal sisters. 

Late one night, Princess Celestia groaned as she slowly woke up in her bed, yawning and stretching her hooves. Something inside her had stirred her from sleep. Hearing her pull-up squish under her rump, she squeaked as the sun princess could feel some cold liquid against her rump. She looked down with a blush. "Oh dear, not again."

Celestia groaned, getting up and leaving the bed to see a large wet spot on the sheets. This made the princess quite flustered just as she heard her sister walk into her room in a crinkling pull-up.

Luna snickered in a mocking tone. "Looks like little Tia peed last night. You’re such a little piddle pants."

"Stop being such a pest, Lulu! Besides, why didn't you wake me up if you knew I had to go?!" Celestia cried, showing off her sagging pull-up.

Luna reared back at the smell of urine and snapped. "You don’t help me go potty, sister. Why should I help you?!" 

"You're so mean,” Celestia retorted. “You're just trying to look better than me at potty training!"

However, both princesses squeaked as they turned to see Twilight appear in their shared bedroom, giving them a stern glare. Her mane was frazzled and the bags under her eyes made it clear she’d just gotten up. "What is the meaning of this bickering?" She asked, feeling a bit groggy.

Celestia blushed and scrunched her soggy pull-up between her legs as she asked in a nervous tone. "Wh..what are you doing here, Twilight?"

"Well, I put a baby monitor in both of your rooms in case you need me. You and Luna are still toddlers, after all,” Twilight explained. “Now what is going on? This is a lot of bickering, even more than normal." The way she responded made her sound like a concerned mother. A few weeks ago she probably would’ve felt that way, especially when she’d been an alicorn like Celestia and Luna.

Luna pointed a hoof at her sister. "I was just trying to wake Celestia up to use the potty."

"Nah, uh! She just watched and let me pee in my pull-up like the poopy head she is!" Celestia shouted back.

"That’s enough, there’s no need for arguing,” Twilight scolded in a flustered tone of voice. “You two are both doing your very best to be potty trained. You’ve already made a lot of progress this past week. I know you’re not happy with having to re-learn due to Discord's chaos magic, but we just have to make the most of it until everything is back to normal," Then she came over and took Celestia by the hoof. "Now come on, let's take you to the potty, Celestia."

"But I just peed my pull-up!" Celestia whined, now feeling even more embarrassed at being led to the bathroom. It was hard to accept that she was dependent on her faithful student when it used to be the other way around.

"That's ok, sweetheart. You can still try. You probably aren’t done, that’s why you woke up." Twilight gently cooed as she slowly tugged down Celestia's soggy pull-up upon entering the bathroom, and then helped the toddler princess onto the toilet. 

The princess of the sun blushed as she ended up tinkling into the toilet.

Luna snickered at the sight, before Twilight turned her attention to the younger sibling. "Now now, Luna, you should try to go too. But since Celestia has the big potty, you'll use the training one."

Twilight took out a pink plastic potty made for an alicorn of Luna’s size. Pulling Luna’s pull-up down with her magic, Twilight plopped the princess of the night onto the training potty. 

Luna blushed as she also tinkled, making Celestia burst into laughter. But Twilight snapped, "Stop it right now, you two! You're both sisters and should treat each other with respect while you're cursed like this. Instead of fighting each other, you should both assist in each others’ potty training."

"Yes, Nana." Both princesses whimpered. They suspected this sort of name for Twilight wouldn’t go away until they were fully trained and hopefully returned to being big ponies.

"Now, if you’re done going potty, I'm going to tuck both of you both into bed with a fresh bottle of milk." Twilight declared. 

Luna blushed as she replied. "Bu...I dun need to go to be-" Then she squeaked as she was cut off. 

Twilight just used her magic to fix pull-ups around both princess' rumps (a fresh one in Celestia’s case). "I know you don’t think so, but you can watch over your sister and help her go potty during the night. Okay?"

Luna meekly nodded in agreement, unsure if she should try fighting back.

Twilight simply lead both alicorns to Celestia's bed. Then with her horn flashed new sheets onto the bed as the old, wet sheets were thrown into a laundry tub. Tucking the princess under the sheets, Twilight placed a bottle into both of their mouths. 

Twilight watched Celestia slowly suckle on her bottle and kick about under the sheets, making her pull-up crinkle as she drifted off to sleep. Then Twilight faced towards Luna. "So, Luna, will you watch your older sister and make sure she gets to the potty during the night?"

Luna slowly nodded as she responded. "Yes, Nana."

"Good. And when she wakes up and you're asleep, I expect her to do the same with you. You both need to work together, ok?" Twilight cooed, all the while Luna was so embarrassed even as she nodded.

Twilight then disappeared, leaving both princesses alone.


Celestia woke up the next morning, squeaking as she felt a sharp pang in her bladder. She never had as much trouble controlling herself during the day (Luna, she remembered, had always been the opposite). Still, the toddler princess rushed to the bathroom only to find that Luna was already in there! Furiously, Celestia knocked on the door and shouted. "Why are you using my po- I mean toilet!"

"Because I was going to wake you up, and I had to go too!" Luna shouted, followed by a tinkling sound.

"Well hurry up! I don't want another stormy cloud on my potty chart!" Celestia whined while doing a potty dance. Her chart was already filling up fast with them.

"You can hold it. I'm almost done!" Luna abruptly responded. 

"No I can't, I’ve held it long enough! Now open up, or I'm going to tell Na.. I mean Twilight on you!" Celestia snapped scrunching her pull-up between her legs and doing everything she could to hold in her need to pee.

Luna finally came out, her pull-up already back around her rump. "Fine, whatever go ahead and use the potty, you big baby." She grumbled.

Celestia flew into the bathroom as Luna stood outside, hearing her sister grunt and whine with a cacophony of crinkles. "Need some help, sister?" Luna asked with a snicker.

"I can pull down my pull-up myself, thank you very much." Celestia snapped! 

Luna just snickered more as she heard her sister plop onto the toilet. As she waited outside the bathroom she asked. "So, since we’re neck and neck with our potty charts. I wonder who's going to be fully potty trained first, sister?"

"Well, I won't if you keep using my potty!" Celestia snapped back. “It’s not yours!”

"Don't blame me! I was trying to wake you up and I had to go potty! You know you’re such a bedwetter!" Luna retorted. “Don’t drink so much before bed.”

Celestia’s face turned red as she stammered. "...Fine, whatever! But you should've asked first or something…" And she went back to trying to go potty.

Luna rolled her eyes and snapped. "You’re hopeless. No wonder Bucket Bridle soaks his pampers, he gets it from you."

"Take that back! He’s much better at potty training than Cannon Feather! Cannon Feather always messes himself before he can make it!" Celestia argued. “You let him eat sweets too much!”

"You take that back, that isn’t true at all!” Luna retorted. “Cannon Feather does just fine whenever I’m helping him. You must be having a bad influence on him.”

"Girls!" The familiar voice of Twilight snapped. Both princesses squeaked, hearing Twilight's voice from the baby monitor. "What did I say about fighting? Didn’t I tell you to stop?"

"Sorry, Nana." Both alicorns meekly responded.

"It's ok,” Twilight sighed. “Just stop fighting and I’ll give each of you a sunshine sticker on your potty charts. And Luna, if you have to use Celestia's bathroom you’re to use the training potty, understand?"

Luna blushed and whimpered. “Yes, Nana. I’m sorry. I just really had to go and I didn’t want to waste time trying to find my potty."

"It’s alright, I should’ve told you where to find it,” The voice of Twilight responded. “Anyway, once you and Celestia are done, I left you both a bottle of milk on the nightstand, and packed extra pull-ups in your dressers just in case. Let me know if you need anything, ok? I’ll be there soon."

"Okay, Nana." Both princesses responded.

Celestia emerged from the bathroom a short time later, relieved to have just made it. She took the bottle designated for her into her magic. In between gulps of the milk she said to Luna. "Well, since I went potty I'm going to start my royal duties." The sun princess promptly left with a humpf as she walked off, making her pull-up crinkle. 

Luna took her bottle and suckled on it. "Well, I'll go get our foals changed and ready for preschool." She declared, even though her sister had already left.


After tending to both Bucket Bridle and Cannon Feather and sending them off to preschool, the Princess of the Night reluctantly went back to the bedroom and went to sleep. 

She was woken up a short time later by Celestia, who had a rather goofy smile on her face. “Time for a potty break, sister. Come on, you always did have trouble during the day.” 

Luna yawned. “Couldn’t it have waited until I was done with my nap?”

Celestia refused to take no for an answer as she took her tired younger sister to her bathroom and plopped the alicorn down on the training potty. 

Luna blushed as she pushed out a mess and peed into the plastic potty.

Celestia couldn’t help but tease in an overly exaggerated voice. “There, see? That's how you do it, sister. Keep this up and you’ll fully trained in no time."

Luna blushed, feeling quite odd as she sat there, peeing in the potty. "Sorry…I should've done a better job helping you earlier." She apologized to her sister.

Celestia just hugged her sister and warmly replied. "It's ok, we're both learning how to use the potty together. It's quite enjoyable, actually!"

“Even if we’re being babied by your faithful student,” Luna teased. “She’s never going to let us forget this, even when we go back to normal.”

Celestia just grinned. “Well it’ll just be our little secret. But we can worry about that once we’re fully trained and everything is back to how it should be. For now though, let’s try to make the most of this situation.”
