Celestia woke up the next morning slowly rubbing her eyes. The odd feeling of her mattress made her hesitate as she slowly woke up. As her mind finally snap to attention she noticed she looked chubbier and meeped seeing the fluffy diaper. She quickly looked around in confusion. “Wha..what happened?”
She turned to see a chubby light blue coated filly who was sleeping right next to her snoring lightly. Celestia gasped recognizing the foal as Luna. She waddled over and shook her “Wuna wuna, wake up.”
Luna sneezed and stirred awake staring up into Celestia’s big eyes. “Huh Tia ?” She gasped at her voice having not realized her change in age. “why did I wisp!?” The little princess soon saw how much Celestia had changed too. ”Ya a foaw!?”
Celestia blushed “You one too.” She then pointed at Luna’s diaper. Luna looked down to see it was sagging and was stained yellow. Her cheeks flared as she tried to hide it with her hooves, “bu...but how did we turn into foaws!?”
Celestia shrugged as she patted her diaper. “I dun know but my diapee is dwy.”
Luna pouted, “so what!? I potty twain fastew then you.”
“Now now,” Discord peeked over the rails of the crib they been sitting in cooing. “No need to be cranky.”
The two gasp and blushed once more. Celestia flaring her tiny wings rather cute like. “Discord! What is the meanin of dis?”
Luna tried to hide her diaper with a foal blanket. “Ye-yeah why awe we in diapees.”
Discord snickers behind a pay at the adorable actions of the lunar princess. “Oh isn’t it obvious?” When the two shook their heads he continued. “Well you two were bickering like foals just the other day during the party, so little Whoovsie and I agreed that if you argue like foals then you should be them.”
“You can’t keep us as foaws we gots things ta do.” Celestia glared.
The chaotic caretaker just rolled his eyes.“Pfff, it only for today, you are so melodramatic. Surely a single day off won’t hurt?”
“You should have asked,” Celestia pouted, watching as Discord scooped Luna up and pat the diaper.
“You would have said no anyway so why bother.” He proceeded to the change table he set up layin the little blue filly down. “Now hold still Lulu.”
However, Luna was anything but still as she wormed about embarrassed the whole time as Discord was slowed by her squirming. He could even hear Celestia giggling a little from the crib. After finally getting the diaper taped up, Discord sighed. “Doing this by hand is hard but Derpy said it would be more genuine.” He patted the fresh black diaper cradling his little charge a little as she slid back the crib. “See she all clean.”
Celestia stuck her tongue out as if to brag but soon karma caught up too her as she squeaked hearing an hissss as the padding yellowed.
She tried untapping the diaper from her rump using her magic but the diaper didn’t bulge and her stubby horn just sparking harmlessly.
Discord laughed. “Sorry Tia but these diapers are magic proof. Can’t have little ones making a mess now can we?”
He reached down with his free hand and picked the filly up and took her to the changing table.
Luna laughing “haha who is ta soggy butt now?”
Celestia whined as she kicked about. “oh just wait wuwu. You gonna be cranky when you stinky.”
“Nu-uh, you gonna use way more diapees than me.”
“Well, I was potty trained first!”
“You were bedwetter till you were twelve.”
Discord snickered at their bickering letting them argue with each other as he used the distraction to tape up Celestia into poofy padding and even had a little sun printed on the rear. “Haha, you two do bicker like children.”
“Do not!” The two retorted in sync. Discord laughed again as he set the two onto the floor an nudged them along down the yellow hallway.
“Where are we?” Luna looked up only to the floor where the ceiling was which already made her dizzy.
“My house of course, where else would we have a playdate.”
“Someplace dat make sense?” Celestia said watching a fish fly through the air.
“Now that’s no fun at all. Now, I think Derpy should be alone any moment now.” He slid over to the front door snapping his fingers before opening it. A little flash later, and Derpy and little Whooves stood there looking dizzy. “Ah right on time.”
Derpy stumbled a bit before getting her bearings and came inside with Dr. Whooves who was in an adorable onesie with a teddy bear printed on the front. Derpy asked, “so Discord are our little fillies ready for breakfast?”
“Yes indeed, I’ve gotten them changed.”
Derpy smiled as Whooves babbled excitedly “oh wow they weawwy awe foaws! We gonna have so much fun!”
Celestia blushed. ”Wait we gonna be ya pwaymates?”
Whooves nodded. “Yeah we gonna buiwd bwocks, pway with pwushies, dwink babas have diapee changes. I dwoow sometimes but I tink we gonna gots wots of fun!”
Discord laughed seeing the princesses gulp and Luna babbled, “wew we don’t dwoow!”
Not noticing Celestia was chewing on her hoof as she took it out of her mouth blushing, “uh yeah we dun uh dwoow.”
Discord smirked, as he flicked a claw and a pink pacifier popped into the sun princess’s mouth. “well foals are well know to suck on things.”
Whooves waddled up and gave each a light boop on the nose. Luna eeped and covered her’s before involuntarily giggling. The three were soon moved to Derpy’s kitchen as they were set in their highchairs. Luna plays with the little stars she could move about on her tray which mimicked the night sky. Celestia kept sniffing her tray as it looked and felt like a real flower bed.
Whooves had little toys on his tray that he eagerly was batting them around and drooling. He used his hoof to rotated a plastic gear around and around in loop giggling at the other smaller gears that moved because of it. It was like a mini-workshop made for foals.
Derpy smiled, “oh I wish my little Whoovesy could be a foal for more than a year he’s just so adorable.”
She took the jars of foal food from the counter setting them on each tray. With a soft pop, she opened the banana one and spoons it up to Celestia.
As predicted, the little filly made a face sticking her tongue out “icky.” Mush ended up smeared on her cheeks as the magic spoon kept trying to enter her mouth only to get her muzzle dabbed in the foal food.
Luna was given mashed yams and carrots and smacked her lips making the foal food spray all over Discord. “Yum that’s good!” she opened up for the floating spoon letting each blob go in with care. With Discord shaking his head, “
Dr Whooves was eagerly chowing down on his oatmeal as Derpy fed him personally. Discord aww and can't help but chuckle at how messy the two sisters were getting. He took a quick picture for both cuteness sake and maybe a little blackmail /payback for later. “Come on Celestia, eat your num nums.”
“No,” she whined, some more splatting on her nose. “You getting me messy on purpose.”
“Mmm, maybe,” he snickered, hiding his smile behind a paw.
Derpy turned and scolded the filly. ”Celestia if you don’t eat your foal food you won’t have any cake for dessert.”
Celestia gasped. “I wan cake!” The spoonful flew in during her shout and she swallowed having expected some awful taste but was pleasantly surprised. After that, feeding her became much easier.
Luna clapped her messy hooves together and squealed, “yay! Tia wuvs hew foaw food.” She giggled and bounced on her diaper. The magic spoon slips more of her meal in and Luna eagerly ate at it not minding how messy she become.
Whooves was the first to finish his oatmeal and raised his hooves. “Aww dun Mama!”
Derpy daweed, “Aww did you just call me mama?”
He blushed realising at what he just said, “guess my foawish instincts awe kickin in.”
Luna was smearing mashed yams all over her face and Celestia was digging a hoof in her mouth with foal food also spreaded all over her body. Derpy laughed, “my I can’t believe the princesses were such messy foals.”
“Oh yeah and always cute,” Discord smiled. “Well I guess you all need a bath. How about a fun water balloon fight?”
“With soapy water, that sounds dangerous, what if it gets in their eyes?” Derpy mothered.
“Oh don’t worry i’d never let that happen. It be safe for foals.”
Derpy smiled “Well alright I suppose so.”
She looked over as Whooves diaper was starting to smell and the colt blushing. “uh...I poopy.”
Derpy sighed, “okay sweetie i’ll change you then it’s bath time.”
--------
Luna giggled as she held up a water balloon firing it at Whooves. The balloon popped splashing the to the pink soapy water. “Haha, gotcha.”
Whooves was quick to pick up one the balloon and toss it back only for it to hit the solar princess instead. Celestia giggles at the pink bubbles as her mane was drenched and discovered in bath soap. “This is fun.”
Celestia managed to pick one up as well with her magic and toss it a her sister. The battle of washtub was on. A rubber duck came out of some bubbles squirting the princes when she wasn’t looking. “Hey!”
Dr whooves was quick to get the plastic bubble gun and shot bubbles at the princesses. “Ya two fowgots aw about me!”
The fillies laughed getting hit with the bubbles Luna giggled, “that tickwes.”
As they laugh they don’t notice one large bubble encasing them causing the float up in the air a bit.
The rubber duck aims it beak at them again ready to fire its sudsy ammo at them both.
“Flap for it lulu,” Celestia tries to push the bubble as they float there buzzing her soaked wings.
“No we need to pike da bubble.” Luna stabs her horn at the edges of the bubble slipping about as she can’t get grip and ended up sliding tripping her sister in the process. The duck quacks as two mre ducks surround them.
“We will never surrender.” Luna shouted, even as the two slip about in the floating bubble.
whooves gasped and got out a foam sword, “iww poke ta bubbwe.”
He slips and slides his way over and tried poking his foam sword into the bubble but nothing happened. “Uh oh,” He turned looking the ducky general as it quacks. The other ducks inflate with water ready to fire.
The three eep as the torrent of water was shot out at the three as the duckie just laughed. After the wave of water the three stood there all squeaky clean. The ducks pick them up and onto their backs and ride them around the battlefield some like a victory lap. The foal soon giggling together.
Discord soon came in laughing “Oh that was adorable!”
Derpy picked up Whooves nuzzling him on the nose. “Yes it was. Oh my little hero trying to save the princesses.”
“Those ducks cheated,” Celestia pouts, shaking her head as water is send all over the place.
“I found it funny,” Luna retorted, as they were all wrapped up in towels to dry off.
“Yeah, okay it was fun,” Celestia admitted with a blush. A moment later her mane poofed up like a cotton ball causi the other to laugh.
Discord laughed. “Oh, I didn’t know you were into Disco, Celestia.”
Celestia blushed harder. “Stop laughing, it just does dat.”
While the two sisters teased one another, Dr Whooves squirmed, “mama! Mama! Diapee quick!”
Discord poofs a light blue plastic potty with a hourglass on it and Depry sat her little darling on top of it. “Might as well use this while we are in the bathroom.” She sang.
He giggled as he tinkled in the plastic potty his little face was filled with excitement. “I going potty wike a big colt!”
Derpy smiled and cooed, ”yes you are but we should keep you in diapers.”
He nodded, clapping happily. “Yeah stiww that fewt weawwy good.”
The group were soon all diapered back and set down in the living room with all the toys. Discord patted Celestia head. “Well princess, are you having fun?”
Celestia nodded embarrassed to admit that she was having fun on her day off like this.
Luna’s eyes were full of wonder as her foalish instincts over came her with all the pretty colors, “Wow wha do we pway with fiwst!?”
The lunar foal moved to a white patch of carpet and giggles as she jumped feeling lighter as if on the moon. ‘Weee!” she kept jumping up an down across the mat beaming wide as her tiny wings flap. Celestia looked over and giggled. “Lulu you not banished no more.”
Luna suck her tongue out “hehe den I Nightmare Moon hehe.” She jumped around mre on her luna play mat.
Discord smirked, poofing her into black footed pajamas with the darker blue mane coming down her. She giggled,”Wow I wook wike Nightmawe Moon baby.”
She couldn’t stop smiling. “I’ll get you sister, dat playtime shall wast foreva!”
Celestia giggled too as she found a flashlight that shines rainbows. “Haha I got da elements.”
“Nu uh, dat just a flashlight.”
“Oh yeah take dis,” Celestia turned it on and pointed it at Luna making sure not to shine it into her eyes of course.
“Haha, it not working.” Luna teased, as she kept bouncing.
Celestia sat down with a poof an thought about how to save the day sucking her pacifier.
-------
Dr whooves meanwhile went to his plastic workbench that was filled with plastic gears and tools and bowed his back legs as he turned the gears with the plastic screwdriver. Derpy giggled and lowered herself next to her little colt and asked,”what are you making sweetie?”
“I making pwesents fow my new fwiends.” He held up a rattle with little plastic moons inside and shook it about. “This is fow Wuwu.”
He then picked up a sun shaped teether. “I made this fow Tia!”
Derpy was amazed, “ho how did you make those?”
Dr whooves took out a plastic screwdriver and babbled, I dun know I just put this thing in ta pawastic geaws ten a toy pops out.” We turned the gears as it opened up and a bat pony plushie came out. Derpy turned to Discord who blushed,”what? I thought he needed a new foal workstation.”
Tia came waddling up and pointed ot Luna. Whoovie ya gotta help me defeat my sister. I need better elements.”
He turned the gears of his workbench one more time as a little dart gun popped out. “Otay I hewp.”
Tia was amazed and babbled, “I need somthin too!”
Whooves turned the gears watching as six plushies of the elements barriers popped out. He blushed, “uh I guess tey can hewp? But tey pwushies.”
Celestia giggled as the plushies rose to their hooves. “Alright girls let’s do this!” the dolls rushed over the moon mat’s glowing.
Dr whooves shrugged and used his dart gun giggling “take this wuwu!”
Luna giggled seeing that darts stick to her “ha tat does nothin siwwy.”
The colt whined, “nah uh, I hit ya I win!”
Luna stuck her tongue out “Nightmare moon I can be defeated by foam darts.”
Dr whooves shouting. ”Yeah huh.”
“Nah uh.”
As the two bickered Celestia go up the mat too wit her plushies “haha now I got the elements Nightmare, you going down.”
Luna hops into the air and looked at them. “Aww they so cute.”
“Blah blah blah friendship” The Twilight plush said in a squeaky version of Twilight’s own voice, before rainbows shot out to spin Luna around as her nightmare moon costume disappeared leaving Luna back in just her diaper.“Aww ya win.”
“So dizzy.” Luna plops onto her tummy eyes rolling around commercially as her sister gave her a hug.
Dr whooves poked her diaper “ta diaper gots wittwe moons on tem too.”
Luan giggled and kicked about. ”Stop it Whoovesy.”
The two other foals poke her diaper giggling as it grew bigger with each poke no doubt thanks to Discord magic.
Luna whined, “stop I can’t even get up now!”
“Hehe a diaper moon.” Celestia tease as she keeps poking it to make it bigger even as Luna pouts now sitting off the floor because of its large mass.
Dr Whoovesy got out a blue crayon and tried writing his name on the diaper but ended up just scribbling all over it “awww I fowgots how to write.”
Discord chuckled. “Aww good try,” he said using some magic to decorate the large diaper wit the mare in the moon pattern.
Luna pouts cutely. “Cut it out!” She wiggled more as the diaper just rounded out more. “I don’t wanna be inside diaper.”
Celestia giggled “tat sounds wike fun!”
Luan stuck out her tongue again annoyed and wiggled her hooves only to wobble and lose her balance. “uh oh.” She fell backwards with a loud crinkle as her massive plastic bottom swallowed up Celestia underneath it. Luna looked around once she stopped moving. “Huh where Tia go?”
Dr whooves gasped, “oh my” Celestia whined, “whoovesy help!”
He looked around “uh otay i’ww see what I can do?”
He found a baby bouncer shaped like a rocket and strapped himself in giggling. “Oh wow.” He bounced inside giggling as the magical smoke from the engines. “i a..a..astwothingy.”
Celestia wormed underneath th padding. “Mmm, i’m still stuck under luna stupid bottom.”
“Nu uh, you stupid”
“Yeah huh ya a stupid meanie pants! You betta not toot on me.”
“Nahuh.”
“Yeah huh”
Discord and Derpy snickers at the sight. They knew they should help them out, but the moment was just too precious to interrupt.
Dr whooves squealed as the rocket bouncer swerved in the air before pushing into the big diaper and deflating it. The two princesses crawled out laughing.
Dr Whooves crawled out and hugged the fillies. “Yay ya two awe otay!”
Derpy moved over and gave them all a big hug. “Oh im glad you three are having so much fun.scord makes good foalsitter”
Luna squirmed seeing her diaper was missing and feeling something coming “D...D...Derpy!” A puddle soon appeared under the poor filly causing her to blush.
Derpy pets Luna mane “Aww it’s okay accidents happen.” She took the princess to the change mat nearby and began to slip her into a fresh diaper.
Celestia turned to Dr whooves taking the opportunity to talk to him alone. “ya know I dun undewstand is why ya gots picked fow being baby new yeaw? Can anypony be baby new yeaw?”
Dr whooves shrugged, “I dun know weawwy it could be. All I know is it is a family tradition. I suppose extended family would count.”
Celestia giggled, “ya tink I couwd be baby new yeaw?”
She leaned closer to whisper. “I...I weawwy wike being a foaw it’s so much mowe weaxing and fun.”
Whooves blinked. “But who would raise the sun?”
She shrugged, “Lulu could do it. I waise ta sun and ta moon fow a..a..” She tried counting on her whooves, “I fowgots It was wots of yeaws.”
“Well you could just act foalish as a big pony.”
Discord leans down and teased, having overheard it. “Ask guards to change your soggy diapees. Maybe a maid to tuck you into bed at night.””
She squeaked, “no dun ya dawe Discowd! I wawning ya. Ya du tat ya going back into stone.”
“Aww is somepony cranky, must be close to nap time anyway.” He said, redirecting the conversation as he teleports the three to the large crib which just happen to look like a giant pirate ship.
Dr whooves rubbed his eyes at the sudden change and looked at himself seeing he had an adorable sailor suit on. He giggled. “oh this is nice.” His diaper had little anchors printed on it. “Ha cute.”
Luna smiled as she felt her eye patch and her blue and white shirt. “Arrr,” she wave the foam sword around
Celestia stared at herself seeing a parrot footie costume “hey I no pawot. Sqawk!” she covered her mouth at the sound.
Dr whooves giggled as he waddled to the front of the crib and grabbed on the little plastic wheel. “Otay time we sail to slumberland.”
Luna whined “hey I captain and its cawed dweamland silly. I watch over dreams after all.”
“Squak!” Celestia said, stomping her hooves on the plush planks.
Dr whooves turned “so what? I say it slumberland!”
“Nah uh”
“Yeah huh”
Dr whooves wanted to argue more but yawned sitting down and crawling underneath his blankets “otay wuwu ya win.”
Luna crawled over nuzzling him “otay sweepie head.”
She took ahold of the wheel and hummed as she spun it around sighing .”it does nothin why do we foaws have cwazy imaginations.”
Celestia giggled, “wew tat what bein a foaw is gweat we can pwetend and pway!”
Luna nods an tries playing with the wheel again but yawned. “Mmm,” she laid do2n next ot whooves curling up with another blanket.
Celestia didn’t want to nap, but found herself getting sleepy anyway as as soft jingle of a music box echoed through the air like a siren’s song. She snuggled up with her sister. “This has been fun.”
Celestia nuzzled her “I wish we could be foaws again maybe we can ask Twilight to do this with us next time.”
Luna yawned again. “Discord does fun events too can he be daddy?” Celestia nodded resting her head the soft desk o the ship.
Before they knew it the two were deep in deep sleep and Discord giggled thinking of s way to end their special day.
Celestia woke up with a bottle in her mouth as she looked around and saw in a mirror she was an adult but she was wearing a big white diaper and Twilight was in the room. “oh Celestia you’re awake?”
Celestia spat out the bottle blushing. “uh Twilight, Discord did this you see Luna and I were foals playing with Dr wh-”
Before she could finish Twilight lifted the bottle with her magic and plopped it back into the princess’s mouth. “Calm down Tia, Discord told me everything.”
She blushed as Twilight pat the diaper, “now relax and drink your baba. Luna should be up soon and you two can be my foals for a little bit longer.”
Celestia sighed and relaxed seeing Twilight smiling. For some reason I want to say thanks to Discord...
