Chapter One

Don’t Eat Strange Gems
Chapter One
By Scribe Feather

Clawed footsteps echoed through the castle hallways as Spike walked down the long stretches of carpet and tapestries. Even after weeks of living in Twilight’s new castle, Spike found that there were still new rooms to explore, enticing his curiosity to find them out.

His more recent exploits led him down into a quiet room that was well off the beaten path of the castle’s extensive floorplans. Going through a simple wooden door opened things up to a small private study.

The room contained all the essentials one would need to write a letter or study an old map. Wide shelves on the far wall contained small stacks of loosely tied up scrolls and parchment. A large, tan tinted globe sat beside the papers, displaying the various continents of the world. Beside the globe and shelves sat a dusty looking couch.

The couch itself particularly caught Spike’s eye after spending the better part of the day walking around without sitting down once. The three cushioned furnishing had a crystal like backing, matching the other various furnishings found around the castle. The dark blue cushions were dusty and their padding rigid from lack of use.

Before he did anything else, Spike hopped on top of the couch, resting his tired legs for a moment. However the very instant his rump met with the rigid cushion a hard lump pushed back. Closer examination revealed a strange gem hidden underneath the cushion.

The dark green gem was far from a perfect specimen. It’s color and cut was oblong and lopsided, containing a cloudy center that prevented any sort of light from bouncing off of it’s many faces.

And yet despite the imperfections, Spike couldn’t help but lick his lips. Feeling a bit munchy, the imperfect gem seemed all the more tantalizing. Without stalling another second, Spike took a big bite out of the oblong gemstone.

The gem had a delectable and fresh crunch to it, absolutely tasty to the last bite. Despite its rather lackluster appearance, Spike found the gem’s taste to be unusually good. Down to the last bite, he finished his find with a satisfied smile.

For a moment, the dragon stood there, rubbing his belly as the mundane gemstone seemed to sit oh so well in his stomach. The satisfaction only seemed to last a few minutes however as Spike’s stomach suddenly began to growl.

His stomach began to churn and knot, making the dragon wince in slight pain. He could only take a few steps out into the hallway before the pain became too strong to ignore.

However, as quickly as it appeared, the pain suddenly melted away. Before he could even enjoy the sudden relief, a softness grew between his legs. Out of nowhere, a thick, green diaper had suddenly appeared between his legs, nearly tripping him as he walked.

The sudden discovery made Spike squeak a startled, “how the-,” before hastily tugging at the diaper. The magical garment refused to budge, showing to be heavily resistant to Spike’s advances. Even his claws seemed to be dull compared to the deceptively resistant plastic.

Confused and put in a state of panic as he worried about how things could get worse, Spike made a mad dash out of the hallways. The diaper crinkled with each step as the padding bowed his legs out a tiny bit, forcing his stride into a waddle.

He quickly found Twilight, who was spending her time closely examining the large map of Equestria in the throne room.

“Twilight!” Spike squeaked out, rushing to the purple alicorn with heavy pants.

“Spike?” Twilight said, raising her head from the map to see the diapered dragon, “what happened?”

“I don’t know!” Spike exclaimed, “I was just eating a gem I found in one of the castle rooms. I didn’t think it’d do...THIS!” Spike pointed towards the thick diaper for emphasis. In his panicked state, it took Spike’s troubled mind a while to notice a warming sensation that grew around his crotch.

“I told you to never touch strange objects you find, let alone eat them,” Twilight lectured, “you could seriously hurt yourself if you’re not careful.”

“I know I know!” Spike groaned. “Is there anything you can do to fix this?”

“Hm,” Twilight simply stated, tugging at the diaper with her magic. “I’m not quite sure. This is a strange enchantment we’re seeing here.” Twilight tapped her chin in thought, “perhaps it’s some kind of cursed remnant left over by some incorporeal beast. It might need further study before we can truly narrow down possibilities for a cure. You said you found the gem in one of the castle’s rooms?”

“Y-yeah,” Spike stammered, “i-it didn’t look all that magical. I was just hungry!”

“Perhaps if I could find some sort of counter spell, we may be able to reverse the gemstone’s effects on you. As for the diaper, I’m not sure what we can do other then let it leave the same way it appeared.”

As she continued to speculate, Twilight failed to notice a green diaper that was magically materializing around her waist.

“Uhm...Twilight?” Spike tried to interject, but still the pony continued.

“Perhaps we’re over thinking this and it’ll just pass through your system eventually,” Twilight continued, too involved in this intellectual puzzle to give notice to the thick diaper. “There might be a book about it in the castle’s library-”

Her words were cut short as a tight knot grew in her stomach. Her back legs instinctively began to bow out as her diapered rump raised in the air. Involuntary grunts started to come from the pony’s mouth as she was frozen where she stood.

“It’s affecting you too!” Spike exclaimed, realizing that Twilight was soiling herself.

Twilight didn’t respond, too involved with filling her diaper up where she stood like a foal. Her diaper began to bulge profusely behind her, filling up with an unnaturally large mess. The magic infused diaper began to sag as it grew to make room for the sizable mess.

With nothing more then a quick wave, Spike left Twilight to her fate in a fit of panic. He quickly dashed for the next pony who might be able to help.

Spike weaved through Ponyville through the cover of alleyways and bushes. He did his best to keep his humiliating state out of sight, too embarrassed to be seen this way. Through clever movements and well timed distractions, he managed the make his way through town with little to no incident. Just having one pony see him in a diaper would have been too much.

Eventually, after he traveled what felt like miles, Spike arrived at his destination, the Carousel Boutique. Not wanting to risk another second of being seen out in public like this, he quickly let himself in.

Rarity was already hard at work in her various projects when he entered. Rolls of fabric and sewing supplies floated from one end of the room to the other as she multitasked. Assorted mannequin clad in different dresses circled the busy unicorn as she continued to work hard.

Finding himself in the presence of the beautiful pony made Spike realize just how humiliating he looked. He wasn’t hiding the diaper from random strangers anymore, now he was only ten feet away from the one pony he had a deep crush on.

Fast thinking, Spike quickly pulled a length of fabric from a nearby stack, using it to blanket around his lower half as a shield. “Uhm...H-hey Rarity,” he started.

“Oh yes, Spike, hello,” Rarity answered, rushing around the room. “I’m afraid I’m quite busy. Is this urgent?”

Spike’s face flared up as his grip on the cut of fabric tightened. “Y-yeah...it’s pretty important...”

“Well can you make it quick?” Rarity asked as she raised her head from her work, “did Twilight want a dress made of that material?”

“Uhm...no...actually it’s...” Spike took in a big breath of air before suddenly letting go of the cloth. His swollen diaper, now visibly yellow from front to back, hung there in plain sight. “I-I need your help...”

Rarity frozen, completely taken back by the sight of the diaper. All her work was put on pause as she walked up to the dragon. “Uhm...Spike,” she started, “I’m afraid I don’t...do nanny work.”

“What? No no! This isn’t suppose to be here!” Spike’s voice became shaky as he tried to defend his case. “I found this gem in the castle and it turned out to be magic and when I ate it I magically got a diaper on!”

“Does Twilight know about this?”

“She was the first one I ran to,” Spike continued to explain, “but she...it affected her too.”

“So she’s also wearing a...”

“Y-yeah...”

“I might have something that can help,” Rarity answered, “oh but I do hope I still have it.”

“C-could you check now? Please?”

“Yes yes, of course. One moment,” Rarity trotted into the back of the store, disappearing from sight.

Spike was left to his own devices, pathetically squirming from one foot to the other in a nervous dance. After what felt like hours, Rarity finally reappeared.

“D-did you find it?!”

Rarity looked to the dragon with a blank stare. She paused for awhile before blinking once and finally speaking. “I thought I told you to head to Fluttershy’s.”

“Wh-what?! But you said-”

“Ah ah, I will have no back talk from you, mister,” Rarity shooed Spike’s protests, slowly nudging him out the door. “Off to Fluttershy’s. Off you go!”

Regardless of what Spike had to say on the matter, Rarity pushed him out of the Boutique and into the public eye once more. The slow walk through town was agonizing for the diapered dragon as he was practically paraded around by Rarity.

As he walked through town he noticed a few ponies staring. Some wore thick green diapers that magically appeared around their waists not moments before. The magic was spreading.

Spike continued to waddle along as the two made their way out of the main part of town. Their journey eventually took them to Fluttershy’s cottage, a quaint little house that bordered the edge of the dense Everfree Forest.

Rarity did the honors of knocking on the door which was quickly answered by the yellow pegasus, Fluttershy.

“Oh there’s the itty bitty Spikie,” Fluttershy cooed with a warm smile. She gave Spike’s cheek a little pink, absolutely losing it over his cute.

“Hello Fluttershy,” Rarity said with a graceful bow, “a certain baby dragon is in need of a diaper change and I’m fresh out back home.”

“Oh I have plenty of his diapers here. I can change him,” Fluttershy smiled.

“I’m relieved to hear it, Fluttershy,” Rarity answered, “I’m absolutely swamped with work and I haven’t the time to go shopping for more diapers. Would you mind watching him for a bit while I work?”

“No trouble at all, Rarity,” Fluttershy replied, “he’s certainly a well behaved baby dragon.”

Spike tried his best to contribute to the conversation with what he could quickly force out. “But I’m not-”

“Oh thank you, Fluttershy,” Rarity gratefully bowed her head, “I’ll be back later to pick him up. Ta-ta!” She swiftly left, leaving Spike alone with Fluttershy.

“As for you, little Spikey,” Fluttershy finally said, lowering her head to match Spike’s eye level. “Best get your diaper changed before you leak.”

Spike’s cheeks warmed at this comment, noticing that his diaper was thoroughly soaked from only the short hours he had been in it.

Fluttershy gently lowered Spike onto the ground, splaying out his legs to give easier access to the diaper. She gathered a tub of wipes as well as another green diaper that seemed to appear out of nowhere.

“First let’s get this soaked thing off of you,” Fluttershy cooed.

“Good luck,” Spike scoffed as he crossed his arms. “I’ve been trying forever to get this thing off. It’s not getting loose!”

With little effort at all, Fluttershy pulled off one of the diaper’s tapes. This caused Spike to look at the diaper in disbelief and in shock. Fluttershy met his eyes with a knowing smirk. “I think some little fibber just didn’t want his diapee changed.”

Spike didn’t dignify that with a response and instead crossed his arms and pouted. He allowed Fluttershy to pull the diaper off completely and didn’t bother saying a word she pulled out a tub of moist wipes. He was just thankful that each wipe meant less of the smell of urine that hung around him from the diaper.

It wasn’t until Fluttershy brought over the new green diaper that Spike began to protest. “Not another one!” Spike exclaimed, batting the pony’s hooves away.

Fluttershy responded in the same tone one would expect from an understanding mother. “Spikey, you need your diapers so you don’t have accidents on the floor.”

“I’m not GOING to have accidents! I’m not a baby!” Spike quickly exclaimed, “that diaper was just a fluke! It won’t happen again.”

Fluttershy sighed, “well alright. If you promise to be a big boy and not have any more accidents I won’t force you into another diaper.”

“Good,” Spike simply stated, pulling himself off of the ground. “I still need to figure out how to fix all this!”

Without another word, Spike ran out of the cottage, leaving Fluttershy behind. He made a mad dash back into town. With that little detour there was no telling how much worse the infectious magic got. He didn’t have any time to waste.

Suddenly another diaper appeared around Spike’s waist, this one noticeably thicker than the one before. The change of wardrobe caused Spike to panic once more. His destination didn’t matter anymore, now it was just a matter of finding somepony sane whom he could get to fix this mess. He ran further into town, desperate to find anypony who would listen.

His run degraded into a brisk walk and then into a slowed down waddle. Suddenly he couldn’t see the point of running for dear life. Pausing in the middle of town, he couldn’t quite remember why he was running.

His stomach began to growl once again and in an instant he felt his bowels begging to be released.

Thinking nothing more than about relieving the pressure that grew in his bowels, Spike began to squat. In the middle of Ponyville, for anypony to see as they passed, he began to grunt, pushing out a heavy load into the waiting diaper. The already soggy diaper, began to bulge in the back, sinking down as a heavy load was added. The mess was unnaturally large in it’s bulk, nearly doubling the size of the diaper as Spike continued pushing.

After he finally finished publicly soiling himself, Spike slowly opened his eyes. The first thing he saw was Pinkie Pie staring back at him mere inches away from his snout.

“Hi Spike!” the excitable pink pony yelled, nearly knocking Spike off his feet.

“Pinkie! I don’t have much time! I need you to...” Spike’s words quickly trailed off as he leaned to the side and inspected Pinkie closer. There around her waist rested a green diaper, already rather soggy from the looks of it. “But...how could that be?”

“I saw you over here having so much fun using your diapers and I figured I could help ya change!” Pinkie wore the biggest smile.

“I-I what?...No no, no way! I don’t need a-” Spike’s protests were quickly cut off when Pinkie took hold of one of his arms.

“To the nursery!” She exclaimed, zooming off in one direction, pulling the dragon along with her.

In a blur of pink Spike was suddenly whisked away from his spot. At breakneck speeds he was transported to Sugarcube Corner and pulled upstairs into an open room.

The room started out as Pinkie’s room it seemed, but somehow new furnishings popped up around the room. Other then her bed and dresser, Pinkie’s bedroom now had a large toy chest and a sturdy looking changing table that was big enough for a full sized pony. Shelves underneath the changing table were stocked full of the same green diapers that Spike was wearing, varying in size.

Before Spike could fully comprehend what was going on, he was whisked away and deposited on top of the changing table. Pinkie began the diaper change by effortlessly untaping the straining diaper tapes. The diaper released a strong, foul odor into the air once it was opened, but Pinkie’s unusually experience made quick work of it. The heavily used diaper was rolled up into a tight ball and deposited into the nearby diaper pail.

With cheeks still burning hot with embarrassed blush, Spike’s legs were hiked up into the air by a hoof as Pinkie wiped his rump clean of the smelly mess. He could do nothing but cover his eyes in shame as the pony continued to change his diaper.

Suddenly there was a knock at the door, causing Spike to raise his head. Twilight stood in the doorway, still wearing the same green diaper from before. She bashfully looked towards the other two, surprisingly embarrassed about the ordeal.

“Hey Pinkie Pie,” Twilight said with a slight blush, “I was wondering if I could trouble you for a diaper change.”

“Sure thing, Twilight! What are friends for!” Pinkie chirped back, slipping a new green diaper underneath Spike’s butt. “Soon as I finish up Spike over here I can get you changed in a jiffy!”

The new diaper was pulled up between Spike’s legs, delicately taped up snuggly around his waist. Out of the corner of his eye he could see the tapes glow a dark green, likely locking themselves into place until he needed a diaper change again.

He was trapped and the only pony who might have been able to help him was standing in line to get her diaper changed next.

Don't Eat Strange Gems
Chapter Three
By Scribe Feather

✶✶3✶✶

Sweetie Belle rushed out of the Carousel Boutique with a fresh, white diaper crinkling loudly behind her. Scootaloo and Applebloom, donning their own pairs of thick diapers waited impatiently outside.

“What took you so long!” Scootaloo exclaimed, “we were waiting out here for hours!”

“Blame my sister!” Sweetie Belle exclaimed, her voice squeaking in frustrated fumes. “She wouldn’t let me leave the house until I got my diaper changed.”

“Sisters,” Applebloom grumbled as she rolled her eyes, “always ruining our fun.”

“Well whatever! You’re dry now so we can get started,” Scootaloo added as she pulled out a hand drawn map. The map crudely charted out the town of Ponyville as well as small sections of land surrounding it. Certain buildings were circled in red with a thick dotted line connecting them like a treasure map. “I’ve got a number of stops in mind that are sure to have SOMETHING we’re good at!”

“Then less get started!” Applebloom exclaimed, dashing down the street with the other two waddling close behind.

Wasting no time at all, the three diapered fillies quickly set off to find their cutie marks. The adventure led them all over Ponyville, picking up odd jobs wherever they could. Whenever they were fortunate enough to find a pony who needed a task done, the three happily applied themselves, hoping this task would be the one that earned them their cutie marks.

The three friends ventured deeper into the new, diaper centric world without a care in the world. The only thing they seemed to have been worried about was getting their cutie marks. They seemed completely blind to the fact that everypony in town now wore diapers twenty-four seven.

Among a long list of things to try, synchronized swimming was one that seemed the most promising. Applebloom and Scootaloo were certain that something that involved teamwork would be easily conquered by the three friends. In their excitement, the three made a mad dash to the public pool.

The diving board bowed down a bit as the three filles peered off the edge into the deep blue water. The deep end of the pool seemed to stretch for miles as the water grew darker and darker the further down it went. It was difficult to see the very bottom in a pool so deep.

Sweetie Belle was the first to raise her head up, wearing a look of uncertainty on her face. “Are you sure about this?”

“Yeah of course I am!” Scootaloo exclaimed, backing away from the edge to do some quick leg stretches. “Rainbow Dash says swimming is just like flying! It’ll be easy!”

Sweetie Belle wasn’t so convinced. “Yeah...B-but our diapers-”

Scootaloo suddenly interrupted, “You first!”

A sudden shove pushed Sweetie Belle over the edge, causing her to fall into the pool with a big splash. Her thirsty diaper quickly swelled up in the pool, drinking up the chlorinated water. In mere seconds her diaper bloated up to four times its original size, threatening to burst with overfilled gels.

“Scootaloo!” the unicorn filly exclaimed, her face growing red with frustration and embarrassment.

It took all of her strength to keep herself afloat. The overly saturated diaper weighed her down, threatening to pull her to the bottom. She quickly pulled herself into shallow waters, eyes locked onto the large steps that led to dry land.

Sweetie Belle struggled out of the water, pulling with her her swollen diaper that dragged against the ground.

“Anything?” Scootaloo asked.

Sweetie Belle turned towards her flank, raising her back leg a tiny bit to survey the area. Much to her disappointment, her flank remained blank. Nothing was there aside from her diaper’s leg gatherers that now strained against the near bursting diaper.

“Nothing,” the filly unicorn said defeated.

“Hey! You kids can’t be here!” A lifeguard pony suddenly entered the conversation. “Swim diapers only. Those are the rules!”

Scootaloo rolled her eyes at the bossy teenaged pony. “Whatever, we were on our way out anyway.” She stuck her chin into the air and marched past the lifeguard. “Come on, girls.”

Applebloom copied Scootaloo’s pose, raising her chin as well and marching past.

Sweetie Belle was not as graceful. Considering the heavy bulk of her diaper bowing out her legs, the young unicorn struggled as she pulled herself past the lifeguard. The heavily saturated diaper trailed behind her as one heavy, squishy lump.

With synchronized swimming crossed off the list, the three fillies moved onto other things. Immediately next on the long list of things to try was bird watching which had mixed reactions amongst the three fillies. Sweetie Belle seemed the most excited about the idea, looking forward to the beautiful songs of the various local birds..

The three journeyed into the local woods, the thinner parts of the Everfree Forest where the trees were young and spread out. A simple nature blind was set up, allowing the three friends to watch from the privacy of the tent.

Things started out on a strong note for the most part. Sweetie Belle kept the other two invested with her enthusiasm as they spent the following couple of hours watching the world around them. Various birds fluttered by during this time, chirping their little songs on tree branches or foraging for twigs and grass to make their nests.

Sweetie Belle found joy in keeping track of the various birds of the region with their wide range of colored feathers. Even Applebloom kept herself busy by writing down the long list of bird names that Sweetie Belle called out with glee. Scootaloo, on the other hand, couldn’t have been more bored.

The orange pegasus spent most of the time pacing around impatiently. She quickly lost interest in the birdwatching and was sure to tell the other two how disinterested she was. She tried to kill time by drinking the water bottles the three brought with them, but that quickly turned into a mistake.

“Come ooooon!” Scootaloo said in a harsh whisper as she squirmed from one hoof to the next.

“We can’t rush this one, Scootaloo. Bird watching is all about patience,” Sweetie Belle said as she peered through a pair of binoculars. “And quit squirming! Your crinkling’s scaring all the birds away!”

Scootaloo followed directions and quickly slowed her body down. She had hoped that she could hold back her growing urges mentally. Sadly mere moments passed before she regretted standing still.

Bird tweets and faint flapping of wings were suddenly accompanied by a harsh hissing. Scootaloo’s straining bladder had finally lost the fight, emptying into the waiting diaper. The already soggy padding swelled up with the yellow liquid, sagging profusely down between her legs.

The sudden rush of liquids was too much for the diaper to handle. Soon urine began to dribble out of Scootaloo’s leg gathers, beading down her legs and down onto the grassy floor. In a matter of minutes, the young pegasus was surrounded urine soaked, muddy ground.

It was only then that the other two pulled themselves away from their binoculars.

Sweetie Belle blinked, “why didn’t you tell us you needed a change?”

“I-I just needed to go a little bit!”

“That ain’t a little bit,” Applebloom commented, taking a step away from the moist ground.

“We’re gonna have to change you before you make a bigger mess,” Sweetie Belle casually added, digging out the group’s diaper bag.

“But Rainbow Dash usually-”

“Rainbow Dash isn’t here. Now come on. Don’t be such a baby,” Sweetie Belle said as she spread out a changing mat.

After that much needed diaper change, suddenly bird watching didn’t seem as fun as it was to the three fillies. As a group, they decided to move on to other things.

Further down the list of things, rock climbing stood out as one of the more extreme attempts at getting their cutie marks. Rock climbing gear was easy to acquire and the valley town of Ponyville had plenty of cliff faces to scale. Applebloom was the most excited for this, knowing that a bit of physical labor could achieve a lot.

In their inexperience, the three didn’t last long once they began climbing. Rock climbing was surprisingly labor intensive and even with all the required gear, the three friends struggled to get very high off the ground.

Very quickly the three fillies grew tired, fueled only by determination. However it only took a few more feet of travel before even that wasn’t enough.

“I think we should turn back!” Sweetie Belle called up the cliff side. “It’s getting really close to lunch time!”

“We’re almost there!” Applebloom called out, wiping some sweat off her brow. She swung a pick deep into the rock face, pulling the group up a few more inches. “We just...Gotta!” She only managed to pull them up another half inch before something gave way.

The sound of passing gas sounded around them, almost completely drowned out by the mountain winds. Applebloom’s eye’s flung open as her bowels began evacuating into her diaper, tugging down the padding with the heavy weight.

“NOW can we head back?!” Sweetie Belle asked, craning her head away from her friend’s messy diaper.

Applebloom huffed. “Fine...”

Defeated once again, the three regathered at the bottom of the cliff and opted to moving on to the next thing on their list.

“Well okay, so rock climbing isn’t our thing. We’ll just have to try somethin’ else!” Applebloom commented, tugging off her climbing harness.

“We’re not going anywhere until you change out of that dirty diaper!” Scootaloo answered, plugging her nose with a hoof.

“Here, let me help,” Sweetie Belle said as her horn glowed, “at least if I do it I won’t have to touch...well you know...”

Supplies were gathered and Applebloom laid down on the ground on top of the changing mat. Sweetie Belle took in a deep breath as Scootaloo fled to a safe distance. Time to change another diaper.

✶✶4✶✶

Meanwhile Sugarcube Corner was bustling with activity. The packed shop saw an endless stream of diaper clad customers, a long line of them stretching out the front door. The small staff that worked there rushed from station to station to appease the large mass of customers. Sweets and money were exchanged as the crew moved quickly and efficiently.

Pinkie Pie was on cash register duty, cheerfully accepting orders from customers and trading money for freshly baked goods. She stood behind the counter with a big smile, handling the job with zeal. She paid no mind to the moist diaper that lightly slapped against her crotch with every happy bounce she made.

“Here ya go!” Pinkie Pie cheered, sliding a large, pastry pastry box across the front counter. “One dozen of Mrs. Cakes super delicious, double chocolate fudge brownies WITH sprinkles!”

“Excellent!” the stallion patron said with a lick of his lips, “my wife’s gonna LOVE these!” The required amount of money was exchanged for the delicious and decadent sweets and the stallion left without another word.

Amongst the buzzing activity of the busy sweet shop, Pinkie failed to notice a low grumbling that swelled from her belly. As she zipped around the front room, tending to the various customers, her bowels began to send signals, telling her that they were full and needed release. Too involved in her work and friendly banter with customers, Pinkie barely noticed the signals.

Idly, the pink pony rubbed her belly in an attempt to ease the tightness that had grown there. “Who’s next?!” Pinkie called before a mare came up to the counter. “What can I do ya for?!”

“Yes hello, I’m here to place an order for some lemon cake,” the mare answered, “I have a garden party to go to and the ladies have been raving about your delicious...” Her words trailed off when she began to notice Pinkie’s attention start to fade. “Uhm...ma’am?”

Pinkie remained silent, turning red in the face as quiet grunts began to slip out of her muzzle. Her back legs began to bow out as her forehooves hooked the counter for support. A heavy load slipped into her diaper, tugging down the padding, and creating lumps. She shamelessly filled her diaper behind the counter.

Pinkie Pie was never one to hide the fact that she used her diapers for their intended purposes. Where some ponies would excuse themselves, Pinkie happily soiled her diapers whenever the need arose.

Once finished Pinkie let out a sigh, straightening back up and carrying on with the conversation like nothing happened. “Sorry about that. I needed to take care of business,” Pinkie said so casually.

“It’s quite alright,” the mare said equally as casual, “It’s been a long day.”

“I’ll put your order in right away!” Pinkie chirped before trotting out of the room. Her loaded diaper bounced in her stride with each step.

The next handful of customers went by much like this as Pinkie openly waddled around in her messy diaper. Not a single pony found it strange nor did anypony seem to notice. Even Pinkie seemed to be unaware of the extra weight tugging down her diaper.

It was then the front door opened, a tiny bell at the top announcing the arrival of new customers. In walked the three fillies Applebloom, Scootaloo, and Sweetie Belle, each wearing looks of exhaustion and disappointment. The only thing sadder than their expressions were the heavy, yellow diapers that hung on each of their waists.

“Oh hey, girls!” Pinkie Pie cheered from behind the counter. “How’s it going?”

“Terrible, Pinkie Pie,” Applebloom answered with an exhausted huff. “We’ve been at it all day and we STILL don’t have our cutie marks.”

“We tried hang gliding, mountain climbing, interior decorating,” Sweetie Belle listed off.

“Gardening, falconry, photography,” Scootaloo added to the list.

“But no marks!” Applebloom exclaimed.

“Well, how about you help out here? There’s lots to do around the kitchen. Maybe you’ll find something you’re good at!”

Sweetie Belle was the first of the group to raise her head in peeked interest. “You sure Mrs. Cake will let us?”

“Sure! You can even ask her!” Pinkie smiled before turning towards the back kitchen. “Mrs. Cake!”

A few minutes passed before the motherly, blue mare peek her head out through the doorway. “Yes, Pinkie Pie?”

“Can Applebloom, Scootaloo, and Sweetie Belle help us out?”

“Well...I suppose they can man the counter,” Mrs. Cake started, tapping her chin in thought, “but it’s a big responsibility. Are you girls up to it?”

“Yeah!” the three fillies exclaimed in unison.

“Alright then,” Mrs. Cake responded with a single nod. “just stand behind the counter and take the customer’s orders.” Her nose then scrunched up as she sniffed the air, “and uhm...Pinkie?”

“Yeah?”

“Would you mind getting changed? Your diaper’s a bit distracting to the customers.”

Pinkie chirped with an energetic “Okay dokie!” before bouncing out of the room. The lumpy diaper bounced in her stride, tugging at her waist.

The pink pony happily dashed for the steps that led to her bedroom. Mr. Cake caught her halfway as he trotted down to the first floor.

“Hello, Pinkie Pie,” Mr. Cake said in passing, “off to change, I see.”

“Yep!” Pinkie chirped back, “Mrs. Cake said it was distracting the customers.”

“I would have to agree with her,” Mr. Cake answered with a nod as he scanned Pinkie’s diaper. “You really filled that up!”

“I’ll be back in no time!” Pinkie Pie said with a bounce before zooming up the steps to her room.

Her bedroom door was opened and closed in mere seconds as every fiber of her being vibrated with anticipation. It was now in the privacy of her room that she could indulge in her naughty desires.

A big grin grew on her face as a hoof slowly lowered itself onto her lumpy diaper butt. The hoof gradually pressed into the mess, squishing it about inside the diaper, making her shiver with pleasure.

She then plopped down on the ground, landing squarely on the large mess that hugged her rump. “O-oopsie,” Pinkie’s voice quivered as a big grin grew on her face. Her body playfully wiggled in place as the squishy sensation sent shivers down her spine.

The front of the diaper, already yellow from an afternoon’s worth of bathroom breaks, beckoned the naughty pony’s hoof to explore it further. Pinkie ran her hoof down across the length of the diaper, rubbing gentle circles into the swollen padding. She bit her lip as her body flared up red with arousal.

She wanted to enjoy the wonderful sensations, but knew simply rubbing the diaper wouldn’t be nearly as fun. It took every ounce of self control to pull her hoof away from the tantalizing diaper, but the sexually charged pony managed to stand back up. With legs that felt like jello, Pinkie pull herself inched her way to her bed.

The diaper sloshed and sagged about as the energetic and aroused pony hopped onto the mattress. Every fiber of her body quivered as the squishy sensation surged pleasure through her body. She continued to edge herself further by prodding the swollen padding, letting out low moans each time.

In the midst of her arousing playtime, she shoved one of her pillows deep between her thighs, giving her diapered crotch some support. The compressed pillow pressed firmly into the swollen diaper padding, pushing against the soiled garment.

Pinkie Pie moaned, biting her lip as she thrusted against the pillow some more. She slipped into a rhythm, humping the fluffy pillow with aroused enthusiasm. Tiny, cute grunts accompanied the humps as Pinkie’s diaper thrusted itself into the pillow.

Her panting became heavier as her thrusts became stronger. The rhythmic humping inched her closer and closer to that sought after climax she so craved. Her body heated up as her heart beat faster and faster.

Finally one final hump pushed her over the edge. Her body quivered as her legs shook with pent up energy. Her moist sex became slippery and warm as she finally achieved the wonderful climax that vibrated her body with pleasure. Her hips twitched and bucked against the pillow as she rode out the orgasm. Squeaky moans slipped out of the pink pony’s mouth as she quivered with wonderful bliss.

Pinkie remained frozen in place for a few minutes after the fact. The constant waves of pleasure filled her mind with sexual satisfaction as she was finally able to catch her breath. The pillow remained tightly pinned against her diapered crotch, providing fluffy support.

Slowly at first, she regained her breath as her body slowly recovered from the wonderful orgasm. She pulled herself up from the crushed pillow, her back legs still feeling like jello.

She hopped off the bed with a satisfied smile. Her diaper bounced with her, sagging and tugging at her waist.

“Guess I gotta change you now,” Pinkie said as she looked at the swollen diaper between her thighs.

For a minute or two, she just stood there, eyes locked onto the diaper that remained scrunched up between her thighs. Even with the afterglow fading away, Pinkie still enjoyed the feeling of the messy diaper. She just didn’t want to part with it just yet.

After staring at it long enough, Pinkie made the executive decision and waddled over to her dresser. A single, pink diaper was pulled out of the top drawer.

She plopped down on the ground where she stood, spreading out her legs in preparation of the diaper changing. Not wanting to part with such a great feeling diaper, Pinkie just taped the new one over it, doubling the thickness between her legs.

She smiled at the naughtiness as she stared at the double diaper. “Now I can wet it TWICE as much!” Pinkie chirped with a happy giggled.

On the outside, the diaper looked pristine and clean. It’s bulky shape made it look unusual, but it appeared fine on looks alone. There still remained a lingering scent of sex and waste that followed Pinkie’s rump wherever she went, but that was only a minor drawback.

Pinkie regained her happy sproing, the diaper only interfering a tiny bit. She hopped back out of her room with a satisfied smile. She could hardly wait till her next diaper change maybe she’d add a third to the mix.
