Momlestia comes to the rescue

Twilight was walking back and forth, looking extremely nervous as the day turned to night while shouting. “What do I do?! What do I do?!”

Spike was standing by with his claws crossed across his chest, rolled his eyes at seeing how Twilight was overreacting as usual. “Hey! Stop going crazy for five seconds, alright?! You need to pull yourself together.”

“I can’t, Spike! I don’t want my friends to know I wet myself at night! And if I go to the Grand Galloping Gala they’ll know for sure!” Twilight shouted as she stomped a hoof on the ground in frustration.

The young drake shook his head. “Look, you only wet yourself while sleeping so you’ve got nothing to worry about having an accident at the gala.”

The unicorn turned to face her assistant and with a worried expression on her face explained. “No, that’s not the case. I've noticed recently that I struggle to sense the urge to go at night!”

Spike slammed a claw to his face, seeing that the conversation was just going around in a circle and sighed. “Ok then...look, I asked Rarity if I could stay with her tonight to give you some privacy.”

Twilight paused with her eyes blinking as she asked. “Wait, seriously? You did that without telling me?”

Spike nodded and continued. ”Yeah. Look, I think you and Celestia need to talk about all this stuff, and you need to calm down. I think me being here will just make things weird. It’ll only be for tonight.” He then got up, taking a sleeping bag and some other things as Twilight looked down, feeling a bit disappointed in herself and how she treated her favorite little assistant.

Twilight murmured. “I’m sorry, Spike. Hopefully, this will be over soon.”

“Yeah, you’ll be fine without me, so have fun with Princess Celestia, ok? And please try to relax." Spike responded as he left.

As soon as the door closed behind Spike though, Twilight was just standing there and secretly wishing he wasn’t leaving. Now she was alone with thoughts of not only wetting the bed plaguing her thoughts, but the fact that she’d been given tickets to the Grand Galloping Gala, was now wondering how she'd tell her friends she wasn’t going.

The mare was walking back and forth shaking all over as she had all this anxiety and stress going through her. She then heard a hissingsound along with something hitting the wooden boards. Twilight paused as she slowly came to the realization she was peeing! The mare squeaked ,stepping backwards, her heart thumping in her chest at the fact she was peeing and wasn’t even asleep! This made her fears all the more real about The Grand Galloping Gala as tears filled her eyes.

This was a nightmare and the worst part was she wasn’t asleep.

At that moment, Celestia slowly came in through the front door and gasped upon seeing what happened!

Twilight stood there, whimpering. “I...I...didn’t mean for this to happen. I’m so sorry.”

The princess flew across the room and hugged the unicorn, allowing the mare to nuzzle her chest. “Oh, don’t worry about your accident, sweetie. Come on, how about I give you a bath and I'll mop this up?”

“What, no! I’ll mop it up! Yo-hey!” Twilight shouted as she was suddenly lifted up within the princess’s magic and floated upstairs while kicking and whining. “Stop! I'm not a foal, Princess Celestia!”

Princess Celestia chuckled at seeing how foalish her student was acting and casually explained. “Stop being so fussy, Twilight, I'm just going to help you get bathed.” As she entered the mare’s bathroom. The princess turned a faucet on the tub and tested the water with a hoof making sure it was perfect.

Twilight just looked down with her cheeks blushing as she asked. “You're not actually going to bathe me, right? I can at least do that myself.”

Celestia gave a nod and turned the water off as she responded. “Of course you can bathe yourself, Twilight. Now you relax and clean yourself up while I take care of the mess downstairs.” The princess then drifted Twilight down gently into the warm water with her face still pink from embarrassment.

The mare gulped nervously as she whimpered, “Celestia, please...let me clean it up. You shouldn’t be doing this, you're a princess for heaven’s sake!”

“Twilight, it's ok. Trust me, this isn't the first time I’ve cleaned up a mess like that,” The princess cooed as she kissed her student on her head. “Now relax and wash yourself clean. I'll be back soon.”

The princess of the sun then went back downstairs as Twilight just gave an annoyed sigh. She really didn’t like how Celestia was treating her like a helpless foal. But the mare began scrubbing her coat and mane down with soap and shampoo anyway.

By the time Twilight was finished rinsing her fur with water, Celestia was already back upstairs as she asked. “You all done, Twilight?”

Twilight turned towards the princess with a suspicious look and asked. “Yeah, why do-” before the mare could finish, she was lifted out of the tub and was covered in a fluffy towel and dried off, having all the water and fur soaked up in the fluffy cloth.

Once the towel was set aside Twilight looked over at her mentor and asked. “So...all my urine was cleaned up? There’s no trace of my accident.”

The princess of the sun gave a small nod and cooed. “Yes, of course. Now don’t worry about your accident, let’s get your teeth brushed.”

This time, Twilight put a hoof down. She was starting to get annoyed with all of this unnecessary babying. “Princess, I don’t mean to be rude but I can brush my own teeth.”

But Celestia seemed to ignore her student, taking the mare’s toothbrush and slathering it with toothpaste as she explained. “This is a part of your therapy to get you to stop wetting yourself. But I won’t fight you. I'll let you brush your own teeth if you want, it's up to you.”

Twilight paused as she thought things over. The truth was, deep down she was beginning to like Celestia babying her...though she wasn’t willing to admit it just yet. So the mare gave a deep, reluctant sigh and then grumbled. “Fine, just make it quick.”

The princess of the sun gave a nod as she popped the toothbrush in the mare’s mouth and scrubbed her teeth thoroughly. “There, now spit.”

Twilight did so, spitting the minty flavored toothpaste in her sink and asked. “So...why do you want to baby me?”

Celestia popped the toothbrush in her student’s mouth again and started to brush her teeth again as she pondered the question before responding. “Simply put, I just want to experience being a mother. But the chances of that for me naturally are almost none, and seeing you wetting the bed and needing somepony to comfort you at night has awakened something inside me...I mean, if this is too weird we can always stop.”

The princess then took the brush out, letting Twilight spit out the contents of saliva and toothpaste in the sink as she thought over what Celestia said. She hated being treated like this and having Celestia care for her in such a manner. But she was oddly comforted by the feeling of the pony she’d looked up to all her life caring for her.

Twilight turned and honestly answered. “Until this bedwetting stops...I...I would like it if you continue caring for me. Just… just a little, at night."

Celestia beamed a smile as she then took out a foam pink changing pad and laid it on the ground. “Alright then. Will you come lay down so I can diaper you?”

Twilight sighed but by now she had reluctantly accepted wearing diapers for protection at night. The mare laid down on the soft, padded, pink foam as Celestia then lifted the mare’s back legs with her magic, then took out some rash cream and slathered it on her student’s rump. Twilight eeped at feeling how cold it was, but as she got used to the creamy substance it actually felt really smooth and comforting.

Then the princess went about and poured a healthy amount of foal powder on Twilight’s rump. Twilight took in the aroma of the foal powder and it made her feel so light headed. Celestia smirked seeing the mare acting with the foal powder’s scent now heavy in the air and joked. “There you go, you won’t be getting any rashes tonight.”

Twilight’s face flushed red thinking about how her rump had felt so sore all day because of her diaper from the night before as she stammered. “Thanks… I’d rather not have another diaper rash.”

Celestia went about digging through her diaper bag and noticing Twilight’s nervous expression she asked. “Ok, what’s bothering you now, Twilight?”

Twilight looked up at the ceiling as she whispered. “I want to talk to you about The Grand Galloping Gala….I don’t want to go. I don’t want everypony to know about… the diapers.”

Celestia paused and turned with a surprised look on her face. “Oh dear, I know this whole night wetting is making you nervous but I think I have a solution!” The princess then pulled out a thick, plastic square with pink leak guards, and tiny moons and stars printed all over with Twilight's cutie mark printed on the seat of the padding as she proclaimed. “I had some custom diapers made for you.”

Twilight’s eyes went wide as she suddenly exclaimed. “Wait! You told somepony else about all of this?!”

“Oh no no no, of course not,” Celestia replied. “I had some commissioned in secret and made through dummy corporations. They make less noise, and they are still decently made to absorb liquids but don’t swell as much as other diapers. They can even fit beneath dresses while being completely discreet. I made sure your name never surfaced either." Celestia explained as she slowly pulled Twilight’s tail through the back hole of the diaper and slowly placed the mare’s rump on the seat of the padding.

The mare sighed, feeling the padding against her rump as she laid her head back, rubbing her hooves over her face and still so embarrassed and angry as she cried out. “I didn’t ask you to do anything, princess! Please stop! I don’t want to ruin your reputation for me!”

Celestia shook her head and continued as she folded the front of the diaper over her student’s belly, securing the tabs with a gentle touch of her hoof as she cooed. “Twilight, you have no idea what I would do for you. It was my decision to help you and I don’t care what it does to my reputation if it were to leak out, not that it ever would.”

Twilight kicked about in her padding, hearing the crinkles were softer than the diaper she wore the night before and the padding itself seemed to fit around her rump a lot more. The padding was still rather thick but it didn’t feel like it was. The mare blushed as she waddled out of the bathroom with powder puffing out of the leg holes, and she still had a cute, awkward gait as she broke into her new diaper.

She was actually loving how it felt. But the mare still felt odd as she replied. “Ok, even if you commission me special diapers I wouldn’t feel comfortable going. I only told my friends I was interested in not making things look weird.”

Celestia gave a nod, unable to stop smiling upon seeing Twilight walking around her padding. “That’s understandable, and trust me I won’t force you to go to the gala if you’d rather not...Now...do you want some milk before bed? It helped you calm down the night before.”

Twilight scrunched her back legs against her diaper as she turned her head towards Celestia, her cheeks flushed pink again as she gave a small nod.

Celestia came over to her student and asked. “Alright then, what do you prefer: Bottle or straight from my teats?”

The mare gulped as she had to admit the milk tasted better straight from the teat, but it was still too weird for her to say so out loud. So the mare instead bowed her head as she whispered, “Um...bottle please…”

Celestia giggled as she took out an empty foal bottle, placed it beneath her underbelly and used her magic to squirt milk into the bottle. She promptly screwed an amber rubber nipple on top of the bottle and shook it about. She then laid Twilight in her lap and shoved the bottle into her mouth.

Twilight blushed as she chugged down her milk, making cute suckiling noises as she did so.
Celestia waited as Twilight sucked down every last drop of her milk, then turned Twilight around and gave her back a few pats, making her give a small cute burp.

Twilight was quite surprised and squeaked. “I'm so sorry! I don’t know what came over me!”

“It’s fine, cutie milk makes foals gassy, now let’s get you to bed.” Celestia teased but Twilight's ears flattened against her head as she was feeling more like a foal by the minute.

The motherly alicorn slowly laid Twilight in her bed as the princess started to pull her blanket over the mare and cooed. “Hey...if it makes you feel any better Luna tells me she is making progress with your dreams. And my ‘babying’ as you called it earlier is working and making her job a lot easier. You see, the more stressed out about the bedwetting you are, the more nightmares Luna has to subdue within your dream bubble, making it harder to work on taking out the blocks in your mind that's causing these issues.”

Celestia pleaded. “Please be patient before making any rash decisions, maybe Luna will have you all fixed up before the gala and you'll be able to go without diapers. Won’t that be nice?"

Twilight was already feeling a lot better, with her rump well padded and Celestia's reasurances making her feel all the more comfortable. The padded unicorn gave a small nod as she whispered. “Ok, Celestia...I trust you...th..thank you.”

"No problem, Twilight,” Celestia smiled. “Now do you wish for a pacifier tonight?”

Twilight squeaked. “Ye-hmmm.” Celestia instantly popped a pink pacifier into Twilight’s mouth and giggled. "Sorry should've done that slower."

The mare was surprised at first, but slowly bobbed the rubber bulb in her mouth as it helped soothe her as she focused on the rythmic suckling. The princess then tucked Smarty Pants into the unicorn's hooves then took a hoof and checked Twilight's diaper as she whispered, "Only a little wet, no need for a change yet.”

Twilight eyes lit up upon realizing she hadn't even noticed going, but what was more crazy was the diaper blocked out the sound of her peeing. Wherever Celestia had gotten these diapers from they had to be enchanted and must’ve been quite expensive.

Celestia continued her routine as she then placed a baby monitor on her bed and plugged a nightlight in an outlet as it glowed purple in the dark.

Twilight watched Celestia slowly leaving her room and she suddenly felt scared as she rose up spitting her pacifier out and cried out. “Wait!”

Celestia turned around with a surprised look and asked, “yes?”

“May...maybe I’ll sleep better with you staying with me?” Twilight replied, feeling so embarrassed for even asking. She really felt like a little filly asking to sleep with her mom, rather than a full grown mare.

The princess of the sun’s eyes went wide as she was quite surprised by Twilight’s request and whispered. “Are you sure you want me to do that?” Twilight slowly nodded as Celestia walked over and cooed. “Ok, I’ll lay with you until you fall asleep. I have the baby monitor set up for a reason, you know.” She then slowly laid next to Twilight and snuggled right next to her student, who was kicking in her pampers feeling so excited and embarrassed.

Twilight then slowly laid her head next to her warm mentor’s chest, hearing her heartbeat with the motherly alicorn’s wings wrapped around her body.

The princess nuzzled her student close, laid the mare’s head against her chest and watched her slowly fall into a deep sleep. She was unsure of what to do, Should she leave? But if she did, would she wake Twilight up? Celestia blushed, laying down on her pillow and closing her eyes as she decided that it was probably better to just sleep here for the night. “Twilight might need help getting to the potty anyway with her new pampers.” She thought to herself.
