Moondiapers

Twilight was in one of the towers in Canterlot castle late one night, she was busy reading over a notebook by Princess Celestia labeled foal spells. The desk was a mess, with coffee mugs scattered all over the table and spell books stacked dangerously high on the right end of the table. But Twilight didn’t care as she was fascinated by the notebook. “It’s amazing! These spells are so advanced!”

She then paused in her reading and placed the book down and turned towards a letter near the left side of the table.

Dear Twilight

I found a old dusty book on how fun it is being a foal and I want to try some new spells with you and your friends. If you could, please review my notes; even though I was once your teacher your way better at translating powerful spells. Please be careful.

From Princess Celestia

Twilight gave a loud yawn as she sipped a cup a coffee and turned a page as she thought to herself these spells do look fun, but the question is what does Princess Celestia want to do with them? Then all of a sudden Moondancer stumbled into the room with a few notebooks stacked together with magic and placed them next to Twilight’s books as she exclaimed, “Wow looks like Celestia really went all out on these spells! I wonder why she’s so interested in diapers?”

Twilight shrugged as she took a quill and dipped it in red ink and began scrawling on a piece of parchment. “I have no idea, but some are extremely weird bordering what is known as chaos magic. I'm labeling the weirder transformations in red.”

Moondancer smirked taking a notebook and hoofing it to Twilight. “Here’s my notes on the inanimate transformation spells ”

Twilight took the notebook and placed it on the side yawning. “That’s nice, I guess we did enough for tonight.” She then turned to and stared outside seeing the moon setting.

Moondancer wasn’t ready to give up as she gulped and asked, “Tw..Twi...Twilight?”

Twilight turned with a tired smile. “Yes Moondancer?”

Moondancer gulped shuffling in her hooves and asked, “H...How...about we try a spell just a quick test.”

Twilight shook her head and began walking towards her bed. “No way we can’t risk it, besides a lot of those inanimate spells are extremely embarrassing and dangerous. I won’t allow anypony to use them. In fact i'll be sure to tell Princess Celestia we should end all research on diaper transformations. I just see no reason for anypony to turn into a diaper.”

Moondancer gasped shifting her glasses. “Bu...but Twilight! We made the spell! We created it over weeks of studying!”

Twilight was adamant shaking her head no. “There’s no way i’m going to test this spell onto anypony it’s to risky.”

Moondancer groaned crossing her forehooves over each other. “You were always like this back when we were study partners. You never did learn to take risks.”

Twilight sighed and continued, “Moondancer? I don’t know the reasons why Celestia has us research these spells. But I can't in the right mind have ponies turn into diapers. Your research wont be a total waste we can think of something better for inanimate transformations, trust me.” As she yawned and stretched her forehooves into the air.

The tired velvet coated mare began trotting to her bed as Moondancer hastily went to her personal notebook and flipped through the pages as she thought. Well if Twilight won’t help me perform diaper transformations i’ll do it on my own! There’s no way I will let all out research go to waste!

Later that morning as Celestia was rising the sun Moondancer held onto a finished page of incantations and diagrams describing the diaper transformation. But she groaned, “There’s no way I can pull a spell like this off. Only a alicorn like Twilight could.”

She turned to another book hoofing through it then giggled turning to a mind alteration spell. “This spell will make a pony acceptable to new experiences.” Moondancer smirked, “excellent all my research won’t go to waste.”

Moondancer turned to Twilight and hesitated watching the mare sleeping peacefully. She thought to herself, do I want to turn to a diaper? It will be super embarrassing but I can’t let all my work go to waste. So the determined mare lit her horn and sent a small bolt of light at Twilight’s head and the alicorn princess only shifted slightly in her sleep. Moondancer sighed in relief and whispered, “okay...um… Twilight you like diapers.”

Twilight mumbled in her sleep. “I like diapers.”

Moondancer giggled oh this is going to be good! and continued, “Twilight you love diapers they’re soft and poofy and they keep you warm and safe.”

Twilight gave a goofy smile and drooled a little as she repeated the words, “I love diapers they keep me warm..and safe.”

Moondancer smirked now for the kill. “Twilight we don’t have any diapers, so your going to turn Moondancer into a diaper."

Twilight whimpered struggling to fight the spell but Moondancer cooed, “it's alright I want to be your diaper.”

Twilight smiled at this and cooed, “I want to turn Moondancer into a diaper.”

She giggled then Moondancer cut off the spell panting. “Barely had enough energy to do that but it was worth it.”

Twilight kicked about and gasped sitting up. “Moondiaper what happened!”

Moondancer giggled at the name and cooed, “nothing Twilight I was going to go to bed just saying good night."

Twilight turns with her eyes peering at Moondancer and replied softly, “okay...uh Moondancer ...um I was thinking about what you said and well...maybe testing the diaper transformation isn't such a bad idea.”

Twilight got up and went back to her desk as Moondancer followed her and replied in agreement. “I agree one hundred percent remember Celestia wanted us to make this spell and she was adamant we succeed.”

Twilight gave a nod. “Right, now let me see…”

She turned through the notes of the spells and smiled. “Okay according to the notes you won't feel a thing in fact you'll still be alive as long as the diaper is intact. I'll wear you for three hours and i’ll try using you once for testing purposes.

Moondancer blushed using me? Well I don't know about that. “wow...um… maybe you don't need to use me please.”

Twilight eyed her and asked, “Moondancer? You said you wanted this so I have to use you to test the spell. If not then this whole thing is pointless.”

Moondancer groaned and asked, “okay so what happens if you use me?”

Twilight explained, “you’ll be cleaned immediately I found a spell to remove all mess and urine from you. But I promise to only pee. I'm not fond of messing myself or you.”

Moondancer gave a blush. “Fine, now that’s in order are we ready?”

Twilight looked over all the notes one more time and nodded, “were ready.”

The purple alicorn read the notes on the table as Moondancer gulped, “Twilight...uh be sure to only let Celestia know about this please?”

Twilight looked up with a smile. “I promise Moondancer in three hours you’ll be back to normal and only Celestia and I will know you were turned into a diaper.”

Twilight’s horn glowed and Moondancer closed her eyes and clopped her hooves in anticipation. This is it! This is when I make history!

The tendrils of magic wrapped around the yellow unicorn until they squeezed together and then a loud poof echoed throughout the tower. Twilight squeaked stumbling backward and landed on her rump. When Twilight finally got up all she could see was big purple clouds where Moondancer was. The purple alicorn gasped in horror, “oh my Celestia! What did I do!”

She ran over and blew the clouds away with her wings revealing underneath a neatly folded light yellow diaper. It had lines of purple and red for the waistband, Moondancer’s cutie mark with a big red moon and little purple star decorating the exterior, with wavy dark yellow leak guards lining the border. Curious, Twilight poked the poofy garment hearing it crinkle underneath her hoof she whispered in disbelief, “It worked.”

She poked the diaper again giggling more. “It worked.”

Than Twilight couldn’t hold in her excitement anymore as she hugged the diaper to her chest rubbing the soft padding across her fur hearing a symphony of crinkles and squealed at the top of her lungs. “It actually worked!”

She kissed Moondancer cutie mark and shouted. “You did it Moondancer! You did it! You crazy mare! We pulled it off!”

She took the diaper and gently stroked the padding and whispered, “its amazing, soft plastic fabric on the outside.”

Twilight then gently placed the diaper on the floor and opened it revealing the soft inner part of the diaper. She slowly pressed a hoof in the gel moaning a little as her hoof sank. “Oh Moondancer you're made of silicone gel.”

She then gently used her horn lifting it into the air and pressed it to her rump. The mare whimpered a little hearing the soft crackling that came after she pressed the foalish garment to her rump. The mare shivered all over before she continued thinking, I can’t believe i’m actually putting on Moondancer!

But Twilight continued to gently tape the diaper around her underbelly making sure to move her tail through a small slit in the back of the diaper. The mare then laid down on the ground and gently taped two sticky tabs over the purple and red front of the diaper and pressed them hard with a hoof creating another round of crinkles. Twilight finished by smoothing the tabs out perfectly over the front of the diaper and laid there admiring the leak guards pressed into her thighs with half of the tiny red moon coming over her crotch. She poked the bottom of the diaper feeling the soft gel mold into her hoof and whispered, “Moondancer you're made of a very high quality silicone gel. Maybe the diaper represents your personality you egghead.”

Twilight blushed with realisation that she was talking to a diaper. The mare then slowly got up and admired the foalish garment in a mirror blushing at how well it rounderd her rump. With the big red moon poking outwards and her tail trailing high above the padded rump. Twilight then began to waddle around smiling at how the diaper only gave her a slight waddle, “a perfect fit Moondancer not too much padding.”

Then the mare felt all the coffee from the night hit her bladder and the purple alicorn smirked devilishly, “well...Moondancer did say she didn’t mind.”

Twilight then let her bladder and sighed hearing the pee fill up the silicon gel and could hear the padding swell between her legs. When Twilight was finished peeing she sat down with a loud squish and pressed another hood into the diaper. “Super absorbent and durable excellent!”

Twilight scrunched her face as her horn lit up poofing the diaper as it went back to its original dry state and Twilight bounced on it making it crinkle. “Alright enough of that I better get to Celestia before she holds court and tell her the good news.”

Twilight got up and thought for a second. “But I need a way to hide the diaper…”

She went to her wardrobe and found she had a simple black dress and pulled it over her head. She blushed turning back to see the skirt of the dress round out where her diaper was. But the fabric of the dress was thick enough to hide the foalish garment, “it's not fashionable but it'll do the trick. Now I just I just need to walk slowly as to not make too much noise.”

Twilight practiced waddling around the room but it was difficult as the diaper made her back legs spread apart a little and created a awkward gait. She tried going slower and it worked making only slight ruffling sounds and her waddle was less pronounced and gave a satisfied nod, “alright that’ll work, I just need to get across the castle.”

Twilight cringed as she came out of the front door of her tower and trotted down the stairs making the diaper crinkling echo throughout the stairway. I better just get this over with!

So she decided to briskly walk down the rest of the steps despite the extra crinkles. The purple alicorn eventually reached the bottom where she looked down a hall filled with the royal canterlot guards standing at attention. The mare whimpered and gulped ok I can do this just go slowly.

Twilight then began her awkward waddle across the hall. With her forehooves going first and slowly moving her back legs. She continued onward with the guards turning towards her hearing the slight rustling she giggled nervously, “oh its uh..the dress it has... um...plastic in it.”

The guards all shrugged as she continued onward with her weird gait until one guard came up and asked, “uh...princess Twilight do you need assistance?”

She laughed nervously waving a hoof. “Oh no i'm fine, it’s uh...just that I uh...have to uh practice dancing!”

The guard chuckled, “oh yes you must be heading off to the garden part.”

Twilight's mouth dropped. “Gar...garden party?”

The guard nodded. “Yes in fact Princess Celestia is out there already.”

Twilight groaned as she screamed in her head. Oh no I completely forgot about that stupid garden party! There’s no way I can get to Celestia right now!

She started shaking with her back legs pressing into her diaper making a wheezing sound from her diaper. This made the entire guard turned towards her and Twilight's face turned a deep red Better think of something quick! Think what would Rainbow Dash do? Then a light bulb lit above the purple mare’s head. She threw a hoof in her face. “Wooh sorry must of been those beans I ate last night.”

The entire guard gave light chuckles as Twilight gave a few nervous giggles. Okay we can just perform the spell again. I'm not risking getting exposed in diapers in front of Canterlot’s elite! “Okay...well i'm clearly not fit for dancing. I better just head back to my room.”

She was about to run off when Luna appeared down the hall. “Twilight! I've been looking all over for you!”

Twilight cringed turning towards the giant dark blue alicorn. I don't have time for this Luna!

The princess of the night flew in and landed before the purple mare who stammered. “He- he- hey Luna I was going to just going back to my room.”

Luna rolled her eyes and scoffed, “oh no your not, My sister has been looking all over for you she said to take you to her personally.”

Twilight squeaked, “Oh I can’t i'm a bit gassy and i'm terrible at dancing! I just want to go back to my room!”

Luna rolled her eyes again, “no excuses we have a party to attend!” Then the dazzling dark blue mare lit her horn and the two teleported in a poof of blue smoke. As one guard sniffed the air and whispered, “is that foal powder?”

The two alicorns teleported right into a crowd of fancy looking unicorns in rich clothing dancing around with Celestia standing aside. Twilight was in complete shock as Celestia came up to her, “Twilight i'm so glad you could make it!”

Twilight scrunching the diaper between her legs and quickly exclaimed, “Celestia I need to talk to you I-"

Celestia interrupted, “Twilight stop being so shy I brought you out here for a reason not just for my little side project.” She gave Twilight a wink as the purple alicorn groaned and shouted, “yes I wanted to talk about that! Its-"

But then Fancy Pants with Fleur strolled up to Celestia who turned to the couple, “now I think you three have met before but were never been formally introduced. Twilight this is Fancy Pants my to go stallion on government in Canterlot.”

Fancy Pants bowed and asked, “How do you do Princess Twilight?”

Twilight gulped doing a slight curtsey making her legs bow, and creating a loud rustiling noise of the diaper her legs. “I’m doing well Fancy Pants.”

Fleur giggled and asked in a sweet tone,“what a funny looking and sounding dress. Is it a new style?”

Twilight who was now sweating nervously took a full wine glass from a table nearby I need something to calm myself this. I can do this I can get through this.

She sipped the wine while stammering, “yes it's a...um a uh new style called...um...a crinkle lacing its supposed to help capture...uh sweat from....dancing.”

She gave a sheepish smile and drank the rest of the wine. Fleur scrutinized over the dress with a steady gaze. “That's quite resourceful how many do you have?”

The purple alicorn stammered pouring herself another glass with her magic. “Oh only one Rarity made it for because I sweat alot when I dance.” She then gulped down another glass.

Fleur blushed, “well I must go and see Rarity and get one for myself I too love dancing but I hate it when sweat stains my dresses.”

Fancy Pants eyed Twilight. “Yes but why are your back legs spread apart? Is that the dress too?”

Twilight squealed gulping down the wine glass think! Think! Rarity always talks about fashion think of something! She explained “well...yeah...the...um...dress has a round bump like a petticoat. I was told their fashionable.” Twilight began pouring herself another glass of wine.

Fleur laughed waving a hoof. “Petticoats have been unfashionable for a hundred years darling, sounds like somepony gave you wrong fashion advice.”

Fancy Pants shrugged, “well it’s no matter that dress is fine and does its job. In fact would you care for dance with me?” Twilight slowly drank her last glass of wine and thought what do I do? If I decline they’ll keep asking questions about my dress. But if I dance there’s a more likely chance somepony will notices im wearing a diaper! But if I only do one dance I can easily excuse myself and get out of this party! Twilight just gave a nervous nod and squeaked, “ok why not?

Fancy Pants smiled and took Twilight by the hoof. “Excellent my dear, now just follow my lead.” Twilight trotted along to the dance floor. When they reached the center, she placed a hoof on his shoulder and grabbed the stallion by the waist. He then grabbed her on the side and they st started spinning around gracefully in beat with the music.

However the diaper also crinkled with every step Fancy Pants was no longer caring about the odd noise but other couples turned their gaze at Twilight who gulped and continued dancing. Calm down...you can do this...just swing to the beat this will be over soon.

Then she felt the wine do its work and she felt her bladder tense up. Fancy Pants chuckled, “Twilight you're quite the natural...did you take lessons?”

Twilight shook her head. “No...I...Well i've always been a free dancer.”

Fancy Pants laughed, “well your doing very well for a so called “free dancer”.”

Twilight felt a pang of needing to relieve her bladder when a odd thought went through her head. Soak the diaper. Twilight had to shake the thought out, gulping and accidently tripped on another mare’s hoof sending her to stumble and she felt a tiny drip of urine get soaked into her diaper.

Fancy Pants asked with concern in his voice. “Are you alright? You maybe a little tipsy from all that wine?”

Twilight laughed it off regaining her footing, “nope not me, I can’t get that drunk from a few glasses of wine.”

Fancy Pants shrugged and continued dancing with the mare as another thought invaded her mind. Do it again this time pee some more!

Twilight threw the thought out but lost track of where she was going and this time bumped her padded rump into another mare’s rump and the loud symphony of crinkles burst from the back making the other mare jump. “My goodness was that a diaper!?”

Twilight shook her head vigorously oh come on! How will I… She then blushed and whispered softly. “Nope no diaper...just uh...my...you know….the red river is flowing this month.”

The other mare blushed knowing what that meant and whispered, “oh sorry didn’t realise aunt flo was visiting. Please pardon me for my outburst earlier.”

Twilight threw a hoof, “it’s alright.”

The mare gave a nod and continued dancing with her husband as. Twilight sighed in relief that the lie worked.Fancy Pants strolled up and escorted Twilight back to the tables. “I think we both had enough dancing for today.”

Twilight sighed and rubbed a hood through her mane. “Sorry for being such a clumsy dancer.”

He laughed, “It's alright how about you sit down for abit you do seem quite stressed about something.”

Twilight could only scoff at the comment. You have no idea.
But as Fancy Pants was pulling out a chair for Twilight. A butler carrying a dozen glasses of wine didn't see the chair and fell over spilling wine all over Twilight's dress and into her diaper! The mare herself went tumbling down realising the loud hisssss of her bladder emptying into Moondancer.

The ponies around Twilight gasped at the commotion and started rushing over to see what happened. The purple alicorn herself was soaked in wine with her rump now expanding from being doubly soaked. The mare was cringing as she could hear her soggy diaper now squishing between her rump and the floor. Hopefully nopony has noticed the diaper I need to be careful about getting up.

Twilight slowly rose to her hooves sighing in relief that the smell of wine was besting the smell of her urine and that her diaper was still intact holding strong. I have to admit Moondancer makes one good diaper She then turned to all the worried guests and gave them a sheepish smile, “oh um...i’m ok just a little soaked is all.”

Fancy pants came up with a determined look printed on his face, “your far from alright, your petticoat and um...other thing must be soaked in wine. We should get you cleaned immediately.”

He clapped his hooves to call some maids as they came over Twilight squeaked no they can’t get anywhere near me! Twilight quickly pointed to the stallion was still on the ground dazed blurted out, “oh no help out the butler first he needs more help than me.”

The maids shrugged and as they helped the butler Twilight got up with her diaper making a loud plop between her legs and making squishy noises as she quickly started to waddle away back to the castle smirking, that butler may have actually saved me now I can get to my tower and change! But out of nowhere Celestia then swooped by snickering as she lowered her muzzle to Twilight’s ear. “Do you need a diaper change?

Twilight could only blush and turned to Princess Celestia who gave her a playful wink and with a glow of her horn the two princesses were gone.

Twilight was now in Celestia’s chamber who was blushing as the Princess of Equestria removed the purple alicorn’s soaked black dress like a little filly. Celestia finished taking it off and couldn't help but daww seeing Twilight in nothing but a light yellow soggy diaper with red wine stains and a yellow tinted bottom. The Princess’s former student could only think i'm standing here in nothing but a soaked diaper in front of Princess Celestia. If she wasn't the one who hired ne to make this stupid spell I would never be able to show my face in Canterlot again!

Celestia just scrutinized over the diaper eyeing the big red moon now sagging to the floor and asked, “so...i'm guessing that’s Moondancer?”

Twilight gave a nod blushing completely dumbfounded. “Yeah.. it is...I tried showing you that we finished the diaper transformation spell but I forgot about the dinner party.”

Celestia eyed the diaper circling Twilight like a vulture and tapped a hoof under her crotch making her squeak. “It's very functional even after all that there's no leaking. Im very impressed with the spell Twilight.”

Twilight gulped now a little scared. “I...I have to ask...wh...why would you want a spell like this?”

Celestia cooed tapping the soggy diaper. “Oh no need to worry about that. I won’t use it for anything devious a little harmless prank really.”

Her horn glowed and Twilight fell onto her back as Celestia hummed untapping the diaper but Twlight put her hooves on the tapes and stammered. “wa..wait I can just use a spell to make it dry again.”

The princess’s horn glowed and removed Twilight’s hooves from the front and cooed, “now now babies can’t play with their diapees.”

She then opened the diaper and removed it slowly and took a box of foal wipes and wiped Twilight’s bottom well with foal wipes and tossed them into a wastebasket.

Then all of a sudden The diaper made aloud poof and what stood was Moondancer drenched in wine and urine gagging, “oh Twilight why didn't you clean me before turning me back to normal!?”

Twilight squealed getting up “it's not my fault! I had to go through a dance party and I had wine spilt all over me!”

Celestia just hugged Moondancer and Twilight and shook them about, “thank you! Thank you! Thank you! for completing the spell!”

Moondancer blushed turning towards Celestia wow I don't think i've ever seen Princess celestia so happy before, “it was no problem really.”

Celestia put Moondancer down and explained. “Now that it works Moondancer you need to give me the notes for the spell and Twilight I need your help casting it.”

Moondancer giggled with excitement and exclaimed, “sure i'll help! Just let me get cleaned up first.”

Twilight shook her head and simply stated, “no way!”

Celestia and Moondancer both turned to Twilight and the princess of Equestria pouted a little and asked, “why not Twilight?”

Twilight growled at the two, “did you see what I had to go through? It was insane! Why on earth would anypony want to turn into a diaper! Sure I get Moondancer because she was psyched about all the research, but who possibly else would want to? I can’t do this Celestia im sorry.”

Celestia was stunned and looked down a bit disappointed, but Moondancer shook her head no way am I being peed on and turned into a diaper for nothing! Moondancer smirked andwhispered, “but you don't have a diaper Twilight.”

Twilight back legs instantly bonked each other as she felt like something was missing between them. The mare blushed, “so..so what?”

Moondancer gave Twilight a devilish grin, “so...if you want me to be your diaper agin were going to need the spell.”

Twilight shouted, “no I can buy my own diapers!” She squeaked putting hooves to her mouth and thought, why did I just said that! Why do I like diapers all of a sudden!

Moondancer just simply continued and asked,“but what if somepony sees you?”

Twilight glared at Moondancer and exclaimed, "i'll make my own using magic! That’s it! i'm not changing my mind!”

Moondancer got closer and whispered. “Ask yourself Twilight...will you ever have a diaper as comfortable as me?”

Twilight gulped, “I….uh…” As much as she wanted to fight the urge to say no she couldn't I really do deep down, want to turn Moondancer back into a diaper.

Twilight was now sweating profusely stomped a hoof and shouted, “fine! I'll give Celestia the spell on the condition you'll be my diaper again!”

Moondancer smirked, “deal."

The two shook hooves as Moondancer skipped off with a smile on her face aright a shower then I make history! Twilight eyed Celestia who cooed innocently, “Twilight trust me i'm only going to use the spell on one pony.”

Twilight still eyeing her former mentor simply asked, “who?”

Celestia laughed, “who do you think? my sister Luna.”
