Twilight opened Flurry’s bedroom door, the room was dimly lit and the night sky was visible through the window. The purple mare made her way over to the filly’s bed, each hoofstep bringing a familiar crinkle as her slightly damp diaper moved with her body. “Flurry, sweetie, you overslept! Your nap should have been over hours ago!”

The Alicorn filly mumbled, slowly waking up from her extended nap. “Auntie Twilight?” She asked still feeling the gentle buzzing of a vibrator inside of her soggy diaper. “I think I need a change.” 

Letting out a small giggle, the mare’s horn lit up a brilliant purple as she gently lifted the filly out of bed. “Hmm, looks like you could use some fun first!” She said enthusiastically as she pressed a hoof into Flurry’s soaked diaper, pressing it firmly against her fillyhood.

Flurry Heart moaned, feeling the padding press firmly against her tingling nethers. “T-That feels good! Can you take the buzzy toy out of my diapee first? It’s starting to make me feel really funny…” The filly said with a small giggle, feeling the exploring hoof gently rubbing her.

“Of course sweetheart.” Twilight replied, laying Flurry down on a nearby changing table. She used her magic to turn the lights on in the room, more thoroughly examining the filly’s diaper. “You look like you had a lot of fun while you were asleep! I don’t think that’s all pee.” She teased  pulling open the tapes of the diaper; The soaked garment falling flat on the table with a thud revealing the wet, pink coated nethers beneath it. “Somepony enjoyed their new toy~”

The pink coated filly let out an excited breath, the cool air of her room brushed against her soaked sex making her shudder. She felt her aunt’s hooves running along her hind legs, slowly working their way towards her toy. “Mommy said little fillies should have special toys to put in their diapers!” She said shifting around on the opened diaper, her fillyhood winking at Twilight causing a small stream of fillycum to dribble out around the small vibrator. Flurry’s eyes fell on her caretaker’s diaper, noticing that it looked much wetter than before her nap. “Your diapee is all wet too~” She teased with a foalish giggle.

Twilight’s muzzle turned a faint red. “It’s only a little damp, thank you!” She said defensively. “Not nearly as wet as yours is!” She paused bringing a hoof to her rear giving her diaper a few pokes. “In fact I can’t even really feel it, And I know I didn’t pee yet!” She explained as she used her other forehoof to gently rub along the edges of Flurry’s slit; She gave a small tug on the toy inside of the filly, giggling at her response.

Flurry squeaked feeling the toy being tugged out of her, once the toy was safely out of her, she let out a sigh of relief. A small shudder ran up the filly’s spine, her hind legs quivered for a moment before a small stream of pee hit the open diaper. “O-Oops, I thought I had already peed…” She said sounding a little upset that she’d had an accident so blatantly.

“That’s okay, that's why you wear diapers! Because you can’t control when you have to pee~” The mare teased, lifting the vibrator up to Flurry’s muzzle. “Give it a kiss for good luck!” She exclaimed, watching the  filly doas she was told. The vibrator levitated to Twilight’s rear, her magic pulling her diaper aside before she slowly inserted the vibrator into her own moist slit and turning it to high before returning the diaper to its normal position. “There we go, I’ll let you play with it some more later.” She said, lowering her muzzle down to Flurry’s nethers and sticking her tongue out. “First let’s clean you up!”

The filly moaned loudly when she felt Twilight’s muzzle brush up against her fillyhood, she could feel the mare’s experienced tongue exploring her tight depths. Each thrust of her aunt’s tongue brough more squeaks, followed by moans. Flurry could hardly contain herself, her hooves grabbed onto the changing table as her orgasm rapidly approached. “W-Why’d you stop?” She asked feeling her aunt pull away, a sticky trail connecting the two. 

“We’re going to try something new that’s all~” Twilight replied, she grabbed a hold of her niece’s soaked diaper, examining it closely for a few seconds. Slowly she brought the padding to Flurry Heart’s leaking fillyhood, pressing it hard against her. “Doesn’t that feel nice? I bet we can make it feel even better!” She teased, rubbing the diaper up and down the foal’s slit. 

Flurry suddenly felt a jolt of pleasure move through her body, resuming the immense amount of pleasure that she had previously been experiencing. “Th-that feels really good!” She squeaked, her fillyhood winking under the soaked garment.

The alicorn mare smiled, feeling her marehood growing warm underneath her own diaper. She let out a soft sigh, feeling her bladder releasing into the slightly damp padding. “It’s not fair if you’re the only pony who gets to be all wet!” Twilight cheered happily, her horn glowed with magic, the filly’s diaper moving up and down her on its own. “I’ll help more in just one second.” 

Gasping in pleasure, the pink alicorn started to thrust her fillyhood into the diaper that was grinding against her, she now badly needed release and was getting desperate. “I-it’s hot and tingly Aunty Twily!” she managed, fillycum leaking out of her and beginning to further soak the already swollen diaper.

Twilight increased the speed of the rubbing, the squishing of sodden padding filled the spacious bedroom, along with the whine of a needy filly. “You can’t cum yet, sweetie, I still haven’t made my diapee sticky yet~” She gasped out, the vibrator buried deep in her marehood finally bringing her own release. Her hindlegs quivered as the orgasm ripped through her body, marecum flooded her now soaked padding, mixing with the residual fillycum of her niece. The mare clutched her hooves around the changing table, it was all she could do to stay on her hindlegs. 

Flurry stared in awe as she watched Twilight’s diaper grow darker and start to sag as it was filled with her marecum, the sight for some reason made her fillyhood tingle more as the diaper rubbing against her crotch started to slow as her aunt began to lose focus. “D-don’t stop! You gotta keep going!” She protested, her tail twitching from side to side and her body trembling at her incredible need to cum.

The mare finally came down from her orgasmic high, she knew it wasn’t fair to leave her niece hanging on the precipice like she had. “D-Don’t worry sweetheart, I’m not done playing with you yet. It’s not fair that I got to cum and you didn’t.” She soothed, stroking a hoof down the foal’s chest to her diaper. Slowly she pulled the diaper away, revealing the sticky mess that was Flurry’s fillyhood. “Oh my, somebody is a very sticky little filly!” Twilight teased giggling.

The cool air of the room suddenly hitting her fillyhood cause the filly to squirm, her slit was tingling and a great warmth had built up inside of her, all she could think about was how badly she wanted to move onto the next part of the ‘game’ and get her reward for being such a good filly. “Twily!” She managed as her vagina winked again, now in open view to Twilight, several small droplets of cum leaking down onto the changing table.

Twilight had teased the filly long enough, she licked her lips and dove back in. Her mouth closed over the foal’s crotch, her tongue slipping inside for a few tastes before she found Flurry’s clit. Now that she’d found her mark, Twilight suckled on the small pleasure nub, trapping it in her mouth until her niece couldn’t take anymore. She pulled away just in time for the first two squirts to land on the changing table, realizing the mess they were making she pressed the diaper against Flurry. “That’s it, good girl, let it all out~”  

Words meant nothing to Flurry at this point, she was riding out one of the more intense orgasms she’d had yet, the sudden wet warmth of the diaper being pushed firmly against her fillyhood made the feeling even better as she let out squirt after squirt into the open diaper, her body shaking and her horn sparking in pleasure as she released, soaking the diaper with so much fillycum that it began to leak out into the changing table.

Twilight continued to rub the diaper against Flurry, each rub more gentle than the last. “Somepony definitely needs a fresh diaper now!” She smiled, her maternal instincts overruling her foalish behaviour for a moment. Ever so slowly she pulled the now leaking garment away from her niece, taking a deep breath the mare planted her muzzle into the cum soaked diaper. She couldn’t help herself, the scent, and the taste was too much to resist. Her tongue lapped up the fillycum that had pooled on the surface of the absorbent padding. Slightly embarrassed at her actions she pulled the diaper from her face, which was burning with blush. 

The filly took several deep breaths as she came down from her orgasm, her eyes were closed as her body recovered, slowly she glanced to Twilight who had just planted her muzzle into the soaked diaper. “That’s silly Aunty Twily!” She managed, looking down at herself on the changing table. “I think I need a new diapee now.”

“Yes, you do.” The alicorn mare said rolling up the old diaper and placing it in the diaper bin. She reached down to the shelf below the changing table and grabbed one of the many thick purple pullups from the shelf. She smiled to herself, knowing just how much Flurry would love the idea of wearing ‘big filly diapers’. “Since you’re such a big girl now, why don’t we try Pullups? I can make them vibrate when wet so you know you’ve been a good filly!” 

The filly frowned for a moment. “Pullups? But I wanna wear diapers!” She paused; “Can they be big filly diapers instead? I can be a big filly and still wear diapees!” 

Twilight giggled nodding her head. “Of course they can! I’ll tell you a secret too, Pullups are just big pony diapers with the sides attached.” She explained, preparing to slide the garment up the filly’s legs when the door suddenly opened.

Standing in the doorway, Shining Armor stood, rubbing his head, his sister’s cum soaked diaper still taped tightly around his rear. “Twilight, I think we should really try to find out what’s wro-” His sentence was cut short as his body was enveloped in a purple aura. 

“And I know just the pony to help show you that they’re just big pony diapers!” The alicorn exclaimed as she concentrated on her brother. “We’ll just save this for later.” She said as the sodden garment was removed from him.

Shining Armor was unable to do anything, he wanted to protest what his sister was doing but for some reason he could no longer speak. The stallion could feel his body starting to turn into a plastic material and his legs turning into some sort of elastic. Before he could realize what was going on, he looked more like a pullup than a stallion. His last attempt to fight the change could be seen as his face was pulled into the seat of the garment, now becoming the interior absorbent core, conscious of everything going on and even still able to see.

The purple alicorn smiled as she observed her work, a purple pullup just like the one that she had originally taken off the shelf, the wetness indicators now included Shining’s cutie mark among the foalish designs. Slowly she started to slide the pony turned diaper onto the filly, her arousal level already rising knowing that her brother would be staring at Flurry’s fillyhood until she decided she had to go, and even then he’d have to wait until Twilight chose to change him back.

Flurry smiled, watching the diaper being slid up her legs and into place snugly. In truth these pullups were rather thick and were glorified diapers with easy open sides. “These are super soft!” She said with a giggle as she tried to close her hind legs. “Feels like a really thick diaper!”

“If we want to continue playing games, you have to prove you’re a big filly by staying dry for a couple of hours okay? I won’t be upset if you pee a little bit, I know you get really into playing with your dollies.” The mare explained, helping the alicorn filly down off the changing table. “We can change my diaper later~”

“But if I gotta wear big filly diapers so do you!” Flurry insisted. “You gotta prove you’re a big filly too! Cause you’ve been wearing diapees like me so you gotta prove it too!” She exclaimed with a squeak. “I can help you change! Mommy says I’m really good at helping change myself when she changes me!” She said, pushing one of her forehoofs firmly into Twilight’s padded rear.

“My diaper isn’t full enough for a change, sweetie.” Twilight said firmly, her body shuddered in arousal when the hoof was pressed into her nethers.  “W-why don’t you play with your toys for a little while? We’ll play our fun new game in a little while.” She said trying to ignore the hoof that was now rubbing her padding.

The filly frowned but removed her hoof from the mare’s padding and began to play with her toys, it wasn’t long however before she felt the need to go once again. “Aunty Twily! I gotta go potty!” She announced, her voice squeaking, bringing herself to her hooves quickly.

The Alicorn mare glanced at Flurry’s thickly padded crotch and smiled. “Well, does little Flurry want to use the potty like a big girl?” She asked, leaving the room for a few moments, only to return carrying a pink training potty. 

Flurry opened her mouth to reply before quickly closing it, taking a step back in hesitation. “W-well you said I had to so we could keep playing our game!” She said, clearly torn between going in her diaper and using the training potty. “Do we still get to play if I use my diapee?” She paused. “Uh, Big Girl PullUps!”

Twilight placed the potty in front of the young filly, seating her on top of it without removing her diaper. “I didn’t say you had to go in the potty!” She said giggling, “But if you hold it for a long time it’ll make it feel really good when you go~” 

Now struggling with holding her bladder, Flurry blushed deeply as she was seated on the potty, the shape of it pushing the padding against her rear differently than a normal chair would. “I d-don’t think I can hold it longer...” She struggled. “Mommy never had me hold it this long!”

“Did Mommy ever play this game with you?” Twilight asked, one of her forehooves snaking down to her crotch. She couldn’t stop herself from rubbing, the sight of her niece struggling to not soak herself was very arousing to her. “Soak your big filly panties for me, okay sweetie?”

Nodding, the pink filly let out a small sigh in relief as her bladder released in what could only be described as a voluntary loss of control as her muscles gave out. A loud hissing noise filled the room as her pullup started to swell; The training liner inside ensuring that she felt what she was doing in her diaper as the wetness spread over her fillyhood. The sensation was rather strange, the pullup was not only enforcing the wet feeling, but it was also starting to send small vibrations of pleasure into her slit. “Th-that feels... Good.”

“It’s going to feel even better soon.” The mare said lifting the filly off the training potty. Twilight set her down on the floor and closely examined her now soaked pullup, one hoof gently prodding the seat and crotch of it. “All squishy and wet! Now let’s have a little more fun.” She said unfastening the sides of Flurry’s diaper. 

Flurry let out a long moan as the pleasuring sensation was slowly pulled away from her fillyhood, her diaper now open and exposing her to the cool room. A small trail of sticky fluid connected the base of her vagina to the inside of the now vibrating pullup. “What are you doing? I thought you said that the diaper would make it more fun!”

Twilight lit her horn once more, slowly pulling the pullup away from Flurry’s fillyhood. She began unfastening the tapes on her own padding, sliding it away and replacing with the soaked pullup. “We’re just changing each other! I’ll wear your big girl diaper, and you can wear my little filly diaper.” She explained while refastening the sides of the pullup. Slowly her old diaper wrapped around the foal’s crotch. “We’ll put your special toy in there too.” 

The filly watched as Twilight pulled the toy out of her own slit, now covered in their combined fluids. She felt her, or rather Twilight’s old diaper being pulled to the side and let out a loud gasp as the toy was suddenly thrust into her slit, sinking deeply into her, still vibrating on the high setting that she had yet to experience. The vibrations were so intense that as soon as her diaper was pulled back into place her back arched and several squirts of fillycum shot into the seat of the already soaked garment, her slit winking as the sticky fluid started to pool, coming out of her faster than the soggy padding could absorb.

“Good girl!” The Alicorn mare praised, feeling Flurry’s old pullup beginning to vibrate intensely. She squeaked, her slit still incredibly sensitive from the powerful orgasm she’d had only a short while ago. “W-What are you doing s-sweetie?” She cried out, her hind legs beginning to shake violently. 

Flurry continued to convulse as her orgasm continued, the vibrating toy prolonging her orgasm as it sent more shockwaves of pleasure up her spine. Between breaths she managed a few words. “F-feeling good!”

Twilight struggled to comprehend what her niece had said, her orgasm was overpowering her body to the point of complete and utter bliss. Without realizing it, Twilight’s tail flagged and her hind legs bent, her control over her bladder and bowels failing her; The thought of filling the pullup like an unpotty trained foal sent her spiraling down into intense bliss with a stronger orgasm. Realizing that not even Flurry had that sort of accident. In her current mindset she realized she was acting more like a foal than her young niece. That was the most powerful, arousing thought she’d ever had. She came down from her orgasm, realizing she’d completely filled the garment like a foal. 

As both ponies came down off of their orgasmic high, Flurry let out a small giggle. “You went potty! I guess I am a big filly and you’re not!” The filly said, rubbing the front of her cum soaked diaper with a hoof.

“Sorry Shiny...” The alicorn mare said, simply blushing sheepishly as she looked back at her full pullup. “It was an accident!” Was all she could manage as she regained her breath.

The End!
