Rarity hummed happily watching the needle dance across the fien blue fabric as she made her latest dress. She held it up to the light once it was done staring at the simple design. The soft sky colour and skirt reminded her of something, but she couldn’t quite figure out where this nostalgia was coming from. “Ah perfect, now let see how it fits.” She entered the main room seeing her sister Sweetie belle by the full body mirror platform. “Alright Sweetie Belle, just hold still” she smiled.
Sweetie Belle rubbed her head a bit confused on how she had gotten to Rarity’s shop but put her hooves up for Rarity anyway. It seemed her sister had asked for her help and she was more then willing to do so. Her eyes scan the simplistic pattern. “Uh isn’t it a little simple for you?”
Rarity pull it down over Sweetie making sure the adjustment were right. “Perhaps, but it meant to look simple helps draw the eye more.” Her hoof patted down the skirt blinking when she saw an odd addition that happen been there before. The white mass of plastic was hugging her sister bottom puffing out form the skirt in a cute manner. “Sweetie Belle, why are you wearing a diaper?”
Sweetie belle squeaked in horror. “diaper!? What do you mean diaper!?” She let out another gasp feeling the pillowy fabric between her legs. “Hey! Rarity what did you do!?”
Rarity squeaked stepping back “what I did! I didn’t put the diaper on you!” She feel back suddenly feeling the strange pillowy substance between her legs as well hearing faint crinkles as she scrunched her legs together. She looked down let out another squeak seeing the white mass around her rump. “What’s going on.” her cheeks redden.
“Aww are my little darlings playing dress up?” The two stare back into the shop seeing their mother in al her glory.
Sweetie blushed trying invane to hide the diaper with the familiar baby dress. “Mom, what’s going on?”
“It’s simple Sweetie Belle, it’s some mommy and daughter time.” she strolled over pulling both into a warm embrace before giving each a kiss on the forehead.
Rarity scoffed. “Well this is very uncouth and foalish please take this diaper off.”
“And what about the time you had us at that ice cream shop, or photos taken.” Sweetie retort oddly not minding her mother soft hugging.
Rarity whined “that was different! I didn't dress you up in diapers!”
“Oh hush rarity poo, you should just relax.” Cookie happily booped her daughter nose watching a cute green dress appear on Rarity’s form, showing off the white padding.
Sweetie giggled admiring the dress. ‘Oh hey i remember that one from the family album.”
Rarity tried to tug at the fabric but it didn’t budge. To top it off matching booties appeared on her hooves too.. “Get this thing off me right now!”
“Rarity stop being fussy or mommy will have to give you a time out.
“But i’m not a foal mother,” Rarity stomped her hooves rather childishly.
There mother giggled ignoring her daughter’s whining.. “oh I know what will make you happy how about we do a foal style fashion show!”
Rarity squeaked “what!? No way the dress is embarrassing enough!”
Sweetie’s mind was regressing as she seemed to giggle and babbled, “Rarity cranky she needs a nappy nap.”
Cookie crumbles ruffled Sweetie Belle’s mane. “Maybe she does, but I think Rarity will grow into her new foalish attire.”
Rarity’s didn’t notice as she started to cloud forgetting what she been upset about. she whimpered. “Mommy I scawed of stages gots stage fwight.”
Cookie pulled Rarity in close to her chest and patted the filly’s diaper. “There, there, it’s alright It's just you, me and Sweetie Belle. Don’t you want to be pretty.
“Uh huh gem sparkly,” Rarity nuzzled into her mother looking around the changed room. It was now a large playroom with a toy runway.
Sweetie Belle crawled around the changed room cooing at the pink walls and runway. She climbed up the steps on it and giggles waddling around on top of it shaking her diaper bottom. “Me model mama”
Rarity can’t help giggle as she gather up the various plushies to make their audience out of. Even sitting them in plastic chairs. She clapped slipping back to her mother. “I wanna be pretty.”
Cookie nodded at Rarity taking both of her daughters to the nearby mirror and brushing their manes and curling their tails.
Sweetie Belle seemed more fascinated by her diaper casually poking at it with a foalish sense of curiosity letting out laughter at how it crinkled and bulge between her legs it felt soft too.
Once the manes were done Cookie thought of some of their old foal clothes making them appear on her daughters. Rarity spun around cooing at her white dress with pink trim along the back and little pink shoes to match.
Sweetie Belle stared down seeing an adorable little bumble bee costume with a foam stinker sticking out on the diaper cover. She snickers feeling the little antenna on her head and the little wings. “Hehe buzz buzz” she nuzzle her mommy again as thanks.
“Oh you both make me so happy, yes you do.” Cookie grinned ear to ear hugging them both once more before nuding them up the small steps on the stage. The plushie animals started to move an clap as they waddle.
A plush Photo Finish blinked sitting in one of the many chairs She held up a large camera focusing on the stage with a smile.
Cookie Crumbles came by “oh thank goodness you’re here I need you to take pictures of my daughters.”
“Of course, we make da magics of da foals.” She gesture her stuffed hoof around dramatically.
Rarity squeaked peeking through the curtains “uh what do I do?”
Cookie cooed,”just come out and do a cute dance you’ll be fine.”
Rarity nodded as she slowly came out blushing waddling across the stage shaking her padded rump.
“Oh, that adorable blush is perfect yes,” Photo snapped a few photos while the foal kept blushing trying to keep her pose but still shy about it.
Rarity came up to the front of the stage and did a cute curtsey “hewwo, I waiwty I thwee and wuve gems and candy!”
Cookie clapped “oh that's so cute what are you going to do for us Rarity?”
She paused for a second. “Um...wana do a dance.” She started to skip around stage with a big smile on her face and Photo finish took a few photos while Cookie smirked: “I hope I can somehow make those appear in real life?”
Sweetie belle peeked out next her little antenna jiggling on her head. She skips out without a care making buzz sounds “buzz buzz me bee, me like honey” she zips about the stage in her yellow and black striped onesie giggling carefree.
Cookie awed clapping her hooves.”Sweetie honey, stay still so Photo can take a pitcure of you.”
Sweetie came up to the front of the stage with some plastic flowers beaming. “Buzz buzz” she stuck her face into the flowers as the plush took a few more photos.
“Yes perfect, so adorable,” Photo plush cooed, making sure not to flash the light in the foal’s eyes.
Cookie couldn’t help stop smiling watching her children pose and waddle around . She soon moved over to Rarity and with care took off her nice dress before sliding a bear onesie on her instead. Matching the brown onesie were large paw booties which Rarity loved as he rubbed them on her cheek.
Sweetie made bee sounds again while holding her flowers. “No, my honey.”
“Rawr” Rarity paws in the air similar to how her cat would before chasing after her sister. The room was soon full of laughter as the two ran around block towers and huge plushies. It wasn’t long until Rarity manage to grab her sister and tickle her fluffy tummy. Sweetie swiftly became a squirming ball of giggles as she tried to stop the ticklish onslaught.
Sweetie pushed her hooves on Rarity’s chest squealing. ‘No hehe pee pehehe.” It took no time at all for the regressed filly to start wetting herself a faint blush on her cheeks.
Cookie let Rarity back up before she scooped up Sweetie in her hooves cradling her in a gentle sway. Her daughter latched her hooves around her mommy’s neck cooing and nuzzling into the neck smelling the vanilla scent. “Aww, my little darling had an accident, yes she did.” The foal laughed a little more as the soggy pamper was given a gentle pat.. Sweetie was slid into her mom’s back as they head over to the changing table.
Rarity giggled following her mommy to the table. “Hehe, Sweetie peed.”
“Yes she did Rarity, since you caused it would you like ot help mommy change her?”
The older foal nodded eagerly “Uh huh, me big sis.” Letting her mommy wipe her sister bottom, she went about making faces at Sweetie. The foal kicked around some during the change booping Rarity’s nose as she cooed.
Once Cookie has slid the fresh diaper under Sweetie she held up her bottom. “Okay Rarity gently sprinkle foal powder onto her bottom.” ‘
Rarity grabbed the bottle of foal powder and poured far too much onto Sweetie Belle’s rump making Cookie squeaked as she drifted the container away from Rarity’s hooves, ”Rarity that's too much!”
The mare blushed “uh sowwie mommy.”
Cookie sighed as Sweetie Belle giggled kicking about poofing foal powder all over. “It’s alright, I guess i’ll just finish the change.”She quickly wiped the excess foal powder off with a foal wipe and taped up the diaper all snug. Rarity feeling bad started to cry a little. Cookie leaned over to her filly cooing softly at her. “it’s okay sweetie you did good. Just next time gently sprinkle the foal powder.”
Rarity smiled and nuzzled her “oaty mama.”
Cookie lowered Sweetie to the floor and pat the bee onesie once more. “Now that is taken care of, how about we have a nice tea party.”
Rarity gasped, clapping her hooves. “tea pawty! Tat sounds wike wots of fun!”
Sweetie Belle seemed ot have regressed a little further unaware of what Cookie was saying. Sehe babbled gibberish bouncing on her rump some more with litle tufts of powder drifting out.
A giant pink plastic table appered in the middle of the room with matching foal safe chairs. Rarity clambered onto one not even caring she was showing off her padded rump to the world. Cookie materialized plushies of Celestia and Luna into their seats all dressed in thick pink diapers and cute dresses. Next to them were a few teddy bears wearing fux with fancy monocles as well.
Sweetie Belle giggled clapping her hooves as her mother lifted her into a booster seat and buckled the regressed filly in. Cookie then went around pouring lukewarm tea into tiny white cups.
Rarity looked around the table, “now tia gots to say you wook cute in ya dwessie and diapee.”
The plushie Celestia bent her head down into her wing as she threw a hoof acting embarrassed.
The Luna plushie tried to drink her tea as it simply soaked into her belly. A button appeared upon her belly that read “push here” Sweetie Belle intrigued leaned over to the princess and pushed the button making the plushie kick about as it peed it’s diaper. The filly giggled, “wuwu peepee.” she managed to say drool running donw her cheek
Rarity gasped “oh that’s so coow!” she then pushed Celestiua’s button causing her to pee the diaper as well.
Cookie laughed “aww guess our plushie princesses drank to much tea.”
Rarity snickered and clapped her hooves. ”can we change their diapers please!?’
Cookie patted her daughter on the head, “A little later Rarity, besides your going to probably need a change too after this.”
Rarity blushed already feeling a little tinkle “uh yeah maybe.” she sipped her cup of tea talking to the plushies about how much she loved her dresses and how she wanted to make the prettiest clothes in all of equestria. Sweetie Belle just took her empty tea cup and began to chew on it.
Luna poked her head in aweing at the adorable little tea party. “Oh is that a plushie of me, that so cute.” She trolled up to the group giving Sweetie Belle a hug before giving Rarity the same ruffling the little one’s mane.
Cookie giggled “sorry for making a plushie version of you, hopefully it’s not like a vodoo doll.”
Luna blushed “well I don’t need diapers if that's what your saying but it’s quite alright. That doll is just adorable. It’s your dream after all”
Cookie nodded. “Oh yes i’m loving it. Mother daughter time make me feel happy.”
Luna took a cup sipping some of the drink. “that’s wonderful to hear now when your ready were having all the foals meet up in the playroom. Come whenever you feel like it. I know you probably want to spend more time with your daughters,”
Rarity turned and asked,”hey wuna? Do ya and tia have to weaw diapees too?”
Luna thought it over for a second before giggling matterizing a pink diaper on her flank to humour the foal. “Yes we do we alicorns princesses work so hard we don’t have time for bathroom breaks. But don’t tell anypony it’s a secret.”
Rarity gasped. “Otay wuna I keep ta secwet.”
Cookie couldn't help herself as she moved up to Luna and tied the cutsie bib to the princess’s neck. It even had a moon on it similar to her reglia. She sat Luna at the table patting th diaper.
Luna’s cheeks reddened. “thanks Cookie can I have some more tea?”
Cokie poured her some of the tea into a sippy cup. “of course drink as much as you want.” Luna smirked knowing Cookie just wanted to have a chance to change her diaper. “Oh I bet you can’t wait until I need a change.”
Cookie booped her nose. “If you do have an accident i’l be here to clean you up. Now no more big pony words.”
Luna blinked letting Cookie control the dream for now to humour her. “uh otay mama/
Rarity giggled again. ‘Yay princess party.”
Oh there an idea,” Cookie beamed as she swapped the outfits on her children for silly frilly ball gowns with pointy hats to match. Sweetie babbled and plays with it some enjoy the feel of it.
Rarity stood up swishing the dress around. ‘Oh me pretty,” she beamed before skipping around the table. She stopped by Luan tugging on her leg. “Dance with me?”
Luna stared into the big puppy dog eyes and gave in standing up with a crinkle. “Oh why not.” she sees the filly beam as they move to an open spot before music began to play The two wiggle about shaking diaper bottom around as they spin and do rather silly moves. Cookie was reminded of the time Rarity took up dancing when she wa young, and it was just as adorably awkward as now. She watched the two swirl for a bit longer before jumping up and joining in helping ot spin rarity around and have fun. Sweetie Belle bobbed her head to the beat banging her cup on the table seeming to enjoy it too.
After what felt like an hour of shenanigans, Luna poofed away the foalish attire on herself and opens the door leading to the joined dream. “Are you ready to go?”
Cook hugged both her daughters close, letting them hold onto her as they move to the door. “Oh yes, let go see how Rarity’s other friends are doing.” The foals cheer following their mother close as they head off through the barrier.
