A Thin, Blurry Line

A Thin, Blurry Line
By Scribe Feather

Sugarcube Corner was unusually lively this afternoon as the ponies inside hastily gathered last minute luggage for the journey ahead. Bags were packed and pastries were stored into a taxi for the trip to the monthly Baker's Market, a gathering place for local chefs and bakers to sell their goods in an open market styled setting. Mr. and Mrs. Cake had missed the last couple events and it only seemed fitting to bring the twins with them to this one.

This month's Baker's Market would be the Cake twins' first. It always felt like a milestone that Mr. and Mrs. Cake looked forward to. Of course, that would mean Pinkie Pie would be left alone till the night.

"Now you're sure you got everything handled?" Mrs. Cake asked, pushing a baby pram with the excitable Pumpkin and Pound cake inside. The two babies were wrapped in blankets to keep them warm during the cooling day.

"It's not the first time I've closed shop, Mrs. Cake," Pinkie said with a big smile.

Mrs. Cake blinked once at the pink pony, not entirely convinced. "Are you sure? Know what you need to do?"

"Yes, Mrs. Cake," Pinkie said as she counted out a mental list of tasks. The same tasks she was told about about ten times now. "Lock the front door, turn the open sign to close, lock the register, pack away the sweets. Easy peasy!"

"Well alright," Mrs. Cake said with an uncertain sigh.

"Don't worry about me! You four have a good time!"

"Come on, lemon pie! We need to go!" Mr. Cake called out as he carried two bags to the taxi.

"Coming!" Mrs. Cake called out before turning back to Pinkie, "last chance to come with us, Pinkie. We could always use an extra set of hooves."

"You have the twins to help you out!" Pinkie joked with a laugh, "besides, somepony's gotta hold down the fort here."

With some coaxing from Pinkie Pie, Mrs. Cake pushed the pram to the taxi and climbed in with the twins in tow.

"Goodbye Pinkie," Mr. Cake called out before the taxi pony pulled away from the house.

"Bye Mr. Cake! By Mrs. Cake!" Pinkie waved excitably to the passing taxi, steadily yelling louder as the carriage got farther away, "Bye Pound!! Bye Pumpkin!!!"

The excitable mare kept waving until the taxi was well on it's way, barely visible to the eye. As soon as the waving was done, Pinkie bolted into the shop, locking the door behind her and changing the open sign to closed.

She could barely contain herself. An entire evening home alone! An opportunity like this only came once in a million!

But before she could have her fun, she had to do her tasks as quickly as possible. The cash register was locked before the sweets were hastily put back in the fridges for safe keeping. Pinkie decided to keep a tray of brownies out in case she got a sweet tooth later on.

With all her tasks done, Pinkie switched to her own agenda. Her ears twitched as she strained to hear for any kind of movement. She listened closely to the upstairs for any floor board creaks, conversations inside the building, and any other sign that she wasn't alone. She wanted to be absolutely sure she was alone to let her subconscious rest from worrying. She heard nothing.

To better ease her paranoia, she did a quick inspection around the house. She checked the kitchen, which was clean, neat, and tidy as a result of Mrs. Cake's 'pre-trip clean up'. The store front was empty and free of any customers. Finally the upstairs were void of any sign of life. Pinkie was alone and it was time to really enjoy it!

A big smile grew on her face as the pink pony bounded to her bedroom and opened a nearby wardrobe. The items found inside were nothing out of the ordinary. A couple dresses hung on hooks to the left and a number of drawers lined the right wall of the wardrobe. While most of the drawers were filled with boring items like socks and pajamas and her super secret, emergency stash of candy, Pinkie was only concerned with the bottom most drawer that was held closed with a sturdy, silver lock.

After extracting the drawer's key from her super secret, ever so hidden hiding spot (inconspicuously taped to the bottom of her bedside lamp), Pinkie unlocked the drawer. She turned the key as the lock clicked open before pulling out the drawer. Inside the drawer was a collection of things. A pack of diapers and an adult sized pacifier were among the secretive stash. Pinkie pulled out each item, pausing a bit to enjoy the sensations and fantasies that each item alone brought to her tingling body.

The last item, buried underneath the infantile items was something that Pinkie had been saving for a special occasion. A powder blue dildo was pulled out of the drawer and joined the pack of diapers and pacifier.

Pinkie Pie carried all the needed items down to the ground floor where she planned to have most of her fun. She grew tired of doing everything in her bedroom. Visually, it wasn't the most interesting and doing everything down here, even if she was completely alone, made the pony excited and aroused just thinking about it.

To start her night home alone, she tied the adult pacifier around her neck with a ribbon, popping it in her mouth. She passively suckled on the soft rubber nipple as she pulled out a diaper from the pack. The pink hued diaper crinkled loudly underneath her touch as she pressed it against her nose to smell it's foalish scents. A chill rolled down her spine as she spread it on the floor. Time for a diaper change.

Doing her best to steady herself, Pinkie positioned herself on top of the diaper, giggling as the soft, plush fabric nestled her rump. She wiggled on top of the pillowy diaper before pulling out the foal powder. A large amount of the foal powder was poured over her rump and front before the powder white inside was pulled up between her legs. It took a few adjustments involving her lifting her rump a bit and moving the diaper around under her, but eventually the pink mare had a fresh, thick diaper taped around her waist.

In one hyperactive, excitable move, Pinkie hopped up onto her feet, reveling in the thick padding that squished between her legs. She smiled as she wiggled her legs a bit, taking in the million different sensations that coursed through her body every instant. She looked back at the diaper to view it from all angles. Especially enjoying the view from between her legs. She felt like a real foal!

'But what's a foal without her bottle?' Pinkie thought as she bounced into the kitchen, a waft of foal powder trailing behind her. Pinkie pulled out a bottle of milk from the fridge, spat out the pacifier that dangled around her neck, and instantly latched onto it. Mrs. Cake would have never let her have a bottle if they were home. "That's for the babies," she'd always say. The act of going against the rules made Pinkie tingle with excitement. She was being a naughty little filly for breaking the rules.

She idly suckled on the bottle as she trotted around the kitchen, exploring it with a new found curiosity. Her diaper crinkled loudly as she waddled from spot to spot, taking in the sights like a curious little foal. She prodded at fun looking, shiny things that littered the kitchen, playfully giggling as the objects reacted to her touch.

Mixing bowls were cool and made funny noises when dropped and banged on with a spoon. Pots and pans made funny hats for the curious pony as she would often play 'dress up' while sitting on the ground with some of them. All the while making a mess of the kitchen, pulling out the utensils and kitchen ware like a real toddler. Pinkie giggled at the metallic mess she made. Just like a real foal!

As she played and suckled her warm milk, Pinkie let her bladder go without giving it a second thought. As she played loudly on the kitchen floor, her diaper warmed underneath her, swelling up and darkening with a wet, yellow hue. Pinkie pretended not to notice like a real foal, but in the back of her mind she smiled big at the squish sensation that grew underneath her.

Just as her bottle was near empty, leaving only a few more suckles of milk in it, she felt her tummy start to tighten up. "Uh ohs," Pinkie smiled as she rubbed her tummy with a big grin. "Baby gotta make poopies!" In the middle of the kitchen that was littered with silver pots and pans, Pinkie lowered her head, the diaper around her waist rising up in the process.

"Mmf!...Hmf!" Pinkie's body tensed up as her diapered rump raised high into the air. "A-ahhh..." Pinkie grunted loudly as she felt her tummy tighten. Her head hugged the wooden floor as her body obeyed her naughty command. The diaper began to bulge as her rump rumbled. The mess pulled at garment as it filled up, bulging out the fabric and advertising the mess inside. "Naughty filly, loading her britches..."

Her pink body relaxed after the last of her mess entered the diaper, gathering around her rump in a gooey bulge. She craned her neck back and tested the mass with a rubbing hoof. "Heehee, no Mr. Cake, I have no idea what stinks." She said to herself as a playful fantasy painted itself in her imagination. "I think one of the twins need a diaper change."

She wiggled her rump a little to really take in the sensation of soiling herself. In her fantasy, Mr. Cake fell for her playful teasing of a ruse and she imagined him walking off to find the twins. Her hind legs quivered at the thought of getting away with such a naughty deed. She wouldn't be able to hide the smelly act in real life, but to pretend, just for a moment, she was able to enjoy the messy diaper. The fantasy made her cheeks flare up in arousal.

With shaky legs, Pinkie trotted about the kitchen. She took in the soft rubbing of the crinkling diaper, the weight of the mess inside, and the smell that wafted around her like a big neon sign that ratted her dirty deed out.

But that wasn't enough for the imaginative pony. Now she wanted to pretend what it'd feel like if the DID know she messed her diapers. "No Mrs. Cake, I don't need a change yet." Pinkie said as another fantasy quickly replaced the last seamlessly. "What's that? You want to check my diaper yourself?"

Pinkie stuck her rump into the air into the face of her imaginary Mrs. Cake. She pressed a firm hoof into the center of the stinky lump, imagining that Mrs. Cake was checking her diaper like she would a real foal. "O-oh! Mrs. Cake! Please don't squish my poopy mess around!" With a big, naughty grin on her face, Pinkie began to smush the messy lump around inside her diaper. She pretended to cringe as if doing such was gross and repulsive to her. However, she could feel her arousal climbing as her back legs quivered. "M-mph...Yes Mrs. Cake, I'm sorry for lying about not needing a diaper change."

Pinkie looked at the imaginary pony with her best, fake puppy dog eyes. "Could you pwease change me now?" Pinkie looked behind her to the imaginary Mrs. Cake who didn't seem all too pleased that Pinkie soiled herself. Pinkie paused before her expression changed, "Please don't make me go out there! There are other ponies there!"

Pinkie Pie did her best to pout, but it only barely hid her excitement in the fantasy. She imagined Mrs. Cake shooing her out of the kitchen and into the front room where the cash register and a line of ponies waited for her. Pinkie pretended to shyly look at the ground, avoiding eye contact with the staring ponies who looked at her, mouth agape.

Pinkie hopped up onto the counter, resting her belly on top of the cool, wooden surface next to the cash register. Her sagging, diapered rump faced the store's main door. In her fantasy, she imagined a group of pony patrons standing in line to buy something. Now they had front row seats of Pinkie's 'punishment'.

"Mph! Don't leave me here, Mrs. Cake!" Pinkie pretended to whine as her legs dangled off the edges of the counter, "everypony can see my diapers!"

The fantasy made Pinkie feel vulnerable and unbelievably aroused. Her heart raced as her mind conjured up this playful story with vivid detail like a waking dream. She imagined so much detail that little by little the dream seemed to take life of it's own. And before she knew it, she was living the dream like it was actually happening. Characters took life of their own and for a moment, the fantasy felt real to the day dreaming pony.

"Yes, I'd like a half dozen of your lemon cupcakes," a male patron's voice said, eyeing Pinkie's diapered rump, "and a spank of that diaper butt."

"Right away sir." Pinkie could hear Mrs. Cake's cheerful voice beside her. "That's ten bits for the cupcakes...And the spank's on the house!"

Pinkie's body lurched forward as the fantasy pony's hoof slapped her diapered rump with a firm 'smack'.

"What do you say to the nice customer, Pinkie?" Mrs. Cake leaned over to the diapered pony who squirmed on the counter helplessly

"Th-thank you, sir." Pinkie whimpered weakly.

"Next!" Mrs. Cake called out as Pinkie cringed, preparing herself for the unknown. "Can I help you?"

"A tray of your finest, brownies please," this time it was a female's voice. She spoke with a regal, well trained dialect.

Pinkie could see a tray of brownies being pulled onto the counter beside her. The brownies were already cut up into even rectangles for easier consumption. "fifteen bits, please."

"Ah, these look exquisite! Here's your bits," the lady patron said. Pinkie suddenly felt the back of her diaper being pulled away from her rump. She felt something being dropped in before the waist snapped back. "And a little something for you, sweetie." Pinkie felt the lady pony tap a soft square bulge on the rump of her diaper. "I hope you enjoy your brownie."

"Th-thank you, ma'am."

"Oh such manners!" The mare said with a happy chuckle. "I think that deserves ANOTHER brownie!"

Once again, Pinkie's diaper was pulled away from her and another brownie was dropped into her mess to mix in with everything else, leaving an unnaturally square bulge on Pinkie's diaper.

"Thank you for the second brownie, m-ma'am."

"You're quite welcome, young filly!" And with that, the mare trotted off with the tray of brownies in tow.

"How much for the diapered filly?" Another stallion voice said.

Mrs. Cake chuckled, "oh, I'm afraid she isn't for sale. But you can change her if you'd like."

"I would love to! Oh, but only if SHE doesn't mind."

"I'm sure she doesn't mind. Isn't that right, Pinkie." Mrs. Cake sternly looked at Pinkie. Pinkie silently shook her head. Mrs. Cake looked like she meant business.

The stallion leaned in with a firm press of his hoof. Pinkie cringed as her diaper squished against her, mashing up the brownies into the rest of the mess. "What do you think, diaper butt? Do you think you need a change?" The stallion spoke into Pinkie's red ear as Pinkie nodded furiously. "Want to be changed out of your poopy diaper?" Again, Pinkie nodded with a whimper.

Pinkie could hear a few murmurs from the other customer ponies who stood behind the stallion. Some laughed at her sagging diaper, others called her cute, or even admitted seeing her like this was hot. All of this happened while the stallion's hoof could be felt rubbing Pinkie's rump, drawing playful circles into it's brown padding. Pinkie's breathing shivered as her arousal stacked on top of more arousal.

"I think she said she wants to be changed right here on the floor." The stallion said out loud to Mrs. Cake.

The motherly mare smirked and nodded in agreement. "That's what I heard."

"What a naughty filly," the stallion said as he leaned in close to the pink pony. "But first, I think somepony's gonna get a little fun in."

She felt the back of her diaper being pulled away as bolts of arousal tingled her body. She felt the stallion's member teasing her tail hole. The stiff member teased her, making her gasp in pleasure. Slowly, the stallion slipped his stallionhood into Pinkie, occasionally pumping out before continuing the rest of the way.

Finally, the stallion's cock slipped it's full length into Pinkie, moist with his pre-cum. Pinkie bit her lower lip as the sensations of the throbbing stallionhood slid in and out of her, causing her to moan.

Pinkie shivered in arousal as she was forced to enjoy the stallion's lustful thrusts. The other customers stared at the sight as Pinkie covered her eyes in embarrassment.

The stallion's stiff cock pumped into Pinkie before her body quickly erupted into a wonderful orgasm. Her tense body spasmed harshly as her body grew warm. She moaned loudly as she rode out the orgasm with a lout pant.

"Good...Girl," the stallion said with a pant as he slowly pulled out of Pinkie's rump. Pinkie could barely answer, her mind clouded by the intense orgasm. Her body was left frozen on the counter as she panted heavily.

Pinkie was left to dangle there either out of sympathy for the panting pony or out of embarrassment for her exposure. Her diaper bunched up to one side as the mess inside was rightfully squished about and mixed together. For a moment, her world melted away. Nothing existed for a moment as Pinkie felt like she was floating in space. Nothing but her and her diaper.

She was finally brought back down to earth by the stallion's voice, "Let's get the naughty baby changed out of her poopy, stinky diapee!"

Pinkie was forcefully pulled up from her counter top perch and pulled up to her feet. Her legs quivered as her diaper sagged. She was pushed down onto the ground where her diaper squished loudly, causing a couple of the customers to laugh loudly. With some coaxing from the stallion, Pinkie was posed into the diaper changing position, her well used diaper clearly seen.

"Phew!" Mrs. Cake called out loudly from behind the counter, waving a hoof in front of her. "So glad I'M not the one changing that diaper!"

The stallion looked at the diapered pony. "You're lucky you're cute!" Her smirks before slipping the pacifier into Pinkie's mouth who happily suckled on it.

The diaper change proceeded as usual. Her well used diaper was untaped and opened, releasing a foul smell for any customer that was foolish enough to smell the air. Her rump was wiped cleaned thoroughly with an old rag before the diaper was pulled out from under her.

"Just LOOK at that diaper!" The stallion smirked as he gave the old diaper's sagging middle a firm pat to demonstrate the weight of the garment. He taped it up securely before placing it on Pinkie's chest as a constant reminder.

A new diaper was slipped under Pinkie Pie before a nice sprinkle of foal powder replaced the foul smell with a light and fluffy one. Quickly, Pinkie was taped securely in the diaper, a couple pats on the front to declare she was done.

"There we go! A fresh new diaper for the naughty filly to make poo poos in!" The stallion cooed the pink pony before helping her up to her feet. It took Pinkie a moment to remember how a diaper felt without her own waste stuck to her butt. "Thank you for letting me change her," the stallion said not to Pinkie, but to Mrs. Cake.

"You're quite welcome, sir. Come back anytime. I'm sure she'll have a big stinky diaper waiting for you," Mrs. Cake smiled and teased.

"I count on it! Until then..." And with that, the stallion bowed his head before walking out of the store's front door.

The rest of the ponies merely lost their color, becoming monochromatic for a moment before fading out of existence. Their voices faded shortly after. Mrs. Cake followed as well, leaving Pinkie alone with her diaper and thoughts.

The pink pony shivered as her imagination replayed the highlights of tonight's play. She'd have to do it again sometime. But for now...Clean up time. With the fresh diaper crinkling between her legs, she proceeded to clean up the area. She didn't want to leave any hint of what she did tonight for the Cakes to find.

Pinkie spent the last half hour she had alone cleaning up. She double checked, triple checked, and QUADRUPLE checked all the rooms she was in that night and even some of the rooms she never stepped hoof in. She made sure every room was how it was when the night started. She was sure to dispose of her diaper deep in the trash outside so snooping eyes wouldn't find it.

She even gave her blue dildo a good cleaning after that night's fun. She smiled as she looked at the thing, hoping to use it again some other night.

The pack of diapers, the pacifier, and the dildo were packed back up into the locking drawer. The drawer was locked and the key hidden once again underneath her bedroom lamp.

And not a moment too late. "Pinkie! We're back!" Mrs. Cake's voice could be heard from downstairs.

Pinkie took a deep breath before trotting out of her bedroom with a faint crinkle. Suddenly the pony stopped when she remembered what she was wearing. The diaper! She was still wearing the diaper!

Stifling a gasp, Pinkie quickly pulled off the diaper, not caring how loud the plastic tapes ripped. She balled up the still dry diaper and tossed it underneath some blankets on her bed. A temporary hiding spot until she had time to properly hide it.

She steadied herself, taking another deep breath before trotting down the steps in her best natural way. "Oh hey Mr. and Mrs. Cake. How was the Baker's Market?"

"Busy, glad there was two of us so we could keep an eye on the twins." Mrs. Cake chuckled as she pointed towards the two sleeping ponies inside their pram. "Pumpkin would have teleported onto the rafters if we didn't keep an eye on her."

"Sounds like it tired you out."

"It did. How about you? How was it holding down the fort?"

"Oh you know...Quiet...Not all that happened."

"Ah, I see you helped yourself to some of the brownies," Mrs. Cake nodded towards the metal tray that sat on the counter, a couple of the squares were missing.

"Mhmm, don't worry though, I put the money in the cash register."

"How were they? Carrot was trying out a new recipe."

"They were...Soft...And squishy." Pinkie answered, holding back a shy giggle.

"I need to change Pound. He pooped himself during the taxi ride back." Mrs. Cake gently pulled the pegasus colt out of the pram and held him in her hooves. "Didn't even wake up from his nap, can you believe that?"

Pinkie shrugged, "guess he didn't mind the feeling."

"I suppose so. Thank you for watching the shop," Mrs. Cake said with a nod before carrying the sleeping colt upstairs.

"No problem. I look forward to doing it again some time!" Pinkie called out with a smile. 'I hope that stallion comes back for a visit soon too,' Pinkie teased herself. She looked forward to the next time she'd have the house to herself.
