Author's Note

Though it is technically unrelated, this chapter could be considered a kind of sequel to one of my other stories, Pinkie's Messy Walk.

[EQG, Pinkie Pie] Accident In Aisle Eight

Pinkie Pie wasn't sure she had ever felt more nervous before in her entire life.

The normally bubbly, outgoing, and energetic pink girl now stood alone and silent in the middle of a long shopping aisle, with her arms crossed awkwardly over her chest as she leaned up against a concrete pole that extended down from the ceiling. She was constantly checking either entrance to the aisle, all the while attempting to appear as casual and unsuspicious as she could in case someone happened to wander by. Unfortunately, it was a little challenging to keep composed while in her current getup.

She was wearing one of her older sleeveless white tank-tops which felt very tight as the thin fabric strained to bridge the substantial gap between her large and quite perky breasts. The visible lack of any kind of bra underneath was also apparent to see due to the prominent indentations poking out from her nipples.

Though, that wasn't the part that necessarily had her on edge. Her somewhat revealing top was paired with a scandalously short microskirt which barely stretched down far enough to hide most of her supple, round ass cheeks. Bending over even slightly would completely expose the cute little blue and white striped panties she had on under it, as well as the well-defined outlines of both her vulva and anus.

Yet despite all of this, her skimpy choice of clothing for this particular visit to the store was still not the primary source of Pinkie's anxiety. That instead came from what exactly she had come here to do in said outfit. Unlike every other person in the store right now, she had no intentions of shopping or working a shift. No, she had a far naughtier motive for visiting her local superstore today. One that, if she were not careful, could easily land her in a lot of trouble and more than a fair share of shame and embarrassment...

For what seemed like the millionth time, Pinkie quickly scanned the open space above the aisle for any of the orb-like cameras that hung around the store. Once she the naughty deed was done, it could technically be passable as having been a genuine accident but were she to be spotted in the act, there'd be little doubt that it was very much on purpose.

What was she planning to do? What could so deeply unnerve a girl who normally would feel little shame walking around in public looking like this? Well, in essence, it was actually quite simple. She was going to poop in her panties.

As bizarre as that might sound to the average person, that was indeed her reason for coming here today. In the past, using her own underwear as a toilet had always been a massive turn-on, but up until this point, she'd only ever indulged in her messy fetish while in private or at least at little risk of being found out. And certainly never in an outfit this revealing or in a place this public...

Yet, over the past few months, she'd become obsessed with finding new and more thrilling ways to enjoy her favorite taboo past time, edging closer and closer to the public eye with each 'accident.' The intense thrill of potentially being caught while indulging in her dirty fetish was something she had come to crave. And so, after much debating, she finally decided to do it. Right here, in the middle of CanterMart.

Almost every little detail had been planned out, from what times the store was at it's least busy, to her escape route once she'd successfully filled her panties. So far, everything was going as planned, and not a single person in the store was any the wiser to what she was about to do. Even wearing something this saucy, she'd failed to draw too much attention from those who did spot her on her way to this specific aisle.

Why this aisle? Well, one of the more difficult roadblocks to overcome had been the many security cameras scattered around the store. Customarily tasked with recording any potential shoplifters in the act, they could easily ruin her plan. With them being so high up, they likely wouldn't be able to see the results of her naughty act, though watching her do it would probably look pretty suspicious.

Yet, even so, she was thankfully able to find one specific aisle in the whole store that was entirely out of view of all of them. Better yet, it was one that rarely ever got visited, being stocked with random nick-nacks and items that a majority of people usually had little to no interest in buying. It was the perfect place for her to fill her underwear to the brim with shit.

Of course, once she'd had her 'accident,' she would need to quickly get out of here and get back to her car in the parking lot. Along the way, she'd inevitably be forced to cross through the sightlines of a few cameras, though hopefully whoever was watching them wouldn't take much notice of the skimpily dressed girl darting by wearing poop-filled panties.

Taking a deep breath, Pinkie tried to calm down her racing heart rate, closing her eyes as she tried to focus on the here and now.

'Come on Pinkie! You've got this!' She thought, trying to wash away the mountain of worry that was keeping her tensed up and antsy. Though she hadn't gone to the bathroom for a few days in preparation for today, she'd still struggle to get anywhere like this.

After looking around one last time and giving an audible gulp, Pinkie slowly turned around so that she was facing the concrete pillar that she'd been leaning against. Bending forward slightly, she slowly spread her legs apart. This caused her skirt to ride up a bit and expose her still pristine panties. This was it. It was truly now or never.

Her pussy was already wet from anticipation as her juices soaked through the front of her underwear. The intense heat between her legs was almost unbearable as she resisted the urge to start touching herself. Taking one last deep breath, Pinkie could feel the wall of solid waste pressing up against the inside of her anus, begging to be let out. It likely wouldn't take much to coax it out either as she'd been desperate to go for a while now and already almost had a genuine accident earlier this morning.

Closing her eyes and biting her bottom lip, Pinkie slowly started to relax her tightly clenched anus. Grunting softly as she tensed her bowel muscles, nothing seemed to happen at first. But then, she felt her waste begin to move. Her breath hitched as she felt her anus widening rapidly, making room for the girthy head of a massive log of shit which peaked out from within her puckered rim.

*Crackle, Frrpt!*

Balancing delicately on the point of no return, Pinkie gulped hard before giving one last decisive push. She gasped as the dense and bumpy turd finally started to emerge, slithering out slowly from her hole. She moaned quietly as it's thick length squeezed out through the rim of her sensitive anus, stretching it wider and wider.

Unable to resist reaching back with her right hand, Pinkie let it glide down over the smooth round curves of her ass, only to freeze as she felt the once sunken seat of her panties suddenly push up against her palm. A squishy warmth bloomed under her hand as her underwear was tented outwards from her cheeks.

*Ftpcchkt!*

The fabric stretched out as far as it could in an effort to keep the incoming log contained, revealing the still-growing brown column through the leg holes of her panties. As the fabric's resistance grew too much, the protrusion finally collapsed, falling down as more poop began slithering out of her at a much more rapid rate. It coiled and bundled up over itself inside her bulging underwear, smooshing and spreading up through her crack.

When the seemingly neverending log finally ended, tapering off from Pinkie's now quite filthy anus, she was left breathless and unable to move. Her eyes were wide as the heat of arousal emanating between her legs was far more intense than anything she'd ever experienced before. It felt like a massive pile of warm squishy clay was being pressed up against her, but as sticky mush was pushed through her crack and even began to seep up into the front of her panties, eliciting a muffled moan from Pinkie.

'I really did it!' She thought, feeling giddy as she finally musted the strength to push herself up from the pole to stand up straight.

With one hand still resting on the apex of the enormous bulge in her panties, she cautiously felt around its bumpy surface just as the pungent smell finally reached her nose. The realization of what, and even more so where, she'd just done suddenly hit her like a freight train. Though instead of filling her with feelings of shame or embarrassment, powerful shockwaves of arousal coursed all throughout her body. It took just about everything she had to not immediately force her free hand down into her crotch to stroke herself to a climactic finish right then and there.

But no, she needed to get out of here first. It would be far too risky to try anything when anyone could happen upon her at any moment. And while now she could maybe pass her bulging underwear off as the result of an accident, she couldn't afford to let anyone see just how wet the front of her panties were right now.

Quickly turning to check the entrances of the aisle, Pinkie was relieved to see that no one had come across her. With a heated sigh, she pulled her right hand away from the huge protrusion in her underwear, though not before giving it a playful little squeeze first. She'd definitely be having some more fun with it once she got out of here~.

Remembering the route she'd planned out ahead of time, Pinkie slowly made her way towards one end of the aisle, all the while she relished the feeling of the warm bulge brushing up against the back of her inner thighs as she walked. It was a constant reminder of the naughty thing she'd just done, and she loved it.

Reaching the end of the aisle, she peered out into the gap between shopping sections, almost forgetting to try not to look suspicious as she looked around for cameras. She knew a few would be able to see her as she made her way across the store towards the exit, but with no other potential witnesses anywhere in sight, she decided to make her move.

With a burst of speed, Pinkie darted across the gap between the aisle and the maze of clothing racks and shelves which made up the women's clothing area. Her heart raced a mile a minute as she quickly checked around but was relieved to see that she hadn't been spotted by anybody. She would need to cut straight through the center of women's clothing in order to avoid the more busy parts of the store.

With a gulp, she spared a glance up at one of the cameras before making her way between the many racks of clothing that thankfully shielded the lower half of her body. A few minutes of carefully making her way through the various racks of clothing, Pinkie was relieved to see one of her planned 'checkpoints' up ahead. It was one of those small changing room areas scattered throughout all the clothing areas in the store. She'd finally have a chance to stop and catch her breath inside one of them! Assuming that they weren't already occupied.

In fact, there would likely be a full-body mirror that would allow her to get a better look at herself...

Getting a little overexcited, Pinkie hastily ran across a small gap between two shelves before dashing through the curtains of one of the changing booths. Thankfully, there hadn't been anybody in it already.

The moment that the small booth's entrance flaps fell closed behind her, Pinkie let out a massive sigh of relief. Looking around, she suddenly gasped as she found herself standing side-ways onto a full-length mirror. Her eyes immediately flicked down to the incredibly obvious oblong bulge that was jutting out from under the rim of her tiny skirt. The once blue and white striped panties were stained brown at the peak of the protrusion too, making it nearly impossible to mistake what she'd done in them.

Anyone who saw her like this would instantly know that she'd pooped in her panties.

Unable to resist, one of her hands drifted down and pressed a few of her fingers over her pussy, forcing her to quickly stifle a loud moan as she realized how drenched with her juices the front of her underwear had become.

'Maybe... maybe I could just give it a few little teases in here~' She thought, slowly slipping one of her fingers up under the taut fabric covering her pussy.

"Pinkie Pie? Is that you in there?" A girl's voice suddenly called from just outside the booth, causing Pinkie's heart to skip a beat as she recognized the voice of one of her closest friends. "Hello? Darling, are you there?"

Pinkie was almost tempted to just stay silent but eventually decided to give a shaky reply.

"Y-yes, Rarity?" She answered back, gulping nervously as she realized that the only thing between them was two lengths of fabric that hung from the doorway.

"Ah, I thought it was you! My, when you sped past a moment ago, I thought for sure I recognized that pink blur, ha." Rarity laughed. "I must say though, I am a bit surprised to see you here today. Were you looking for something to wear?" She asked curiously.

"Y-yep! That's what I was doing! N-nothing else!" Pinkie yelped back awkwardly, thankful that Applejack wasn't around to instantly see through her lie.

"Oh, well, of course. So, ah, what are you trying on in there any- Ough!" Rarity suddenly gasped mid-sentence. "Oh my goodness, gracious!" She exclaimed, her tone of voice shifting as it was clear she was now pinching her nose. "I'm terribly sorry Pinkie but I, unfortunately, seem to have caught wind of something truly awful." Pinkie felt a droplet of cold sweat rolling down her spine as she knew all too well what the young fashionista was talking about.

She needed to think of a way to get out of here fast, or at least find some way to cause a distraction! Being seen after an 'accident' by a stranger was one thing, but she wasn't sure she'd be able to handle one of her best friends seeing her like this!

"Ough, you- *cough* -you'll have to excuse me for a moment, Pinkie Pie. I think I need some f-fresh air," Rarity gagged, followed quickly by the sound of her footsteps racing away.

Seeing her chance, Pinkie poked her head out through the curtains, just in time to see the fashionista racing off in the direction of the bathrooms before disappearing. She felt terrible, knowing all to well that most people didn't enjoy the pungent aroma as much as she did. She made a mental note to bring an apology cupcake the next time they met, preferably at a time when she didn't have a big pile of smelly poop sagging from the seat of her panties.

Thankfully, her planned exit route was not in the same direction that Rarity fled, allowing her to dart out of the booth and start making her way through the latter half of the women's clothing area. After this, she'd almost be home free. All that would remain was a quick trip through the candy aisle and then she'd need to make one last run for the front doors. With how little business the store usually had around this time, there likely wouldn't be that many people coming in or out that could see her.

Finally reaching the edge of the women's clothing section of the store, ironically enough in the underwear area, Pinkie breathed a sigh of relief. She could see the main doors now, and with the exception of a close scare with Rarity, things had so far been going just according to plan.

The rush of excitement and tension that came with rounding each corner was driving her pussy crazy, but unfortunately, she still had a little ways to go before she could safely make a break for her car.

Peering out from between two racks of fancy lingerie, Pinkie felt her heart sink as she saw the size of the gap that stood between her and the start of the adjacent candy aisle. It seemed so much wider now than while scouting it out...

Only once she passed through that aisle would she be close enough to make a run for the exit without a high risk of being caught out in the open. Thankfully, there didn't appear to be anybody in the aisle right now. However, from her current position, she couldn't fully see down either side of the lane she needed to cross without revealing herself too much to one side or the other. While it didn't seem like there was anyone there, they could easily be just out of view.

Pinkie gulped nervously as she reached back to cup the poop-filled bulge hanging down past her skirt, wincing as she realized that there'd be no way to hide it if she was spotted.

"Come on Pinkie, you can do this!!" She chanted quietly to herself, trying desperately to build up the courage she needed.

Checking to the best of her abilities that the coast was clear, she counted down in her head, preparing to sprint across the gap. Maybe if she was fast enough, just like with Rarity, anyone who was there might not notice her?

'3... 2... 1!'

Like a gunshot, she launched out from between the two racks, bridging the gap between her and the candy aisle in only a couple seconds. Immediately ducking into the aisle, she pressed herself up against one side, breaths rapid. After a few moments, she built up the courage to peer out around the corner. She was relieved to see that, as she'd hoped, there hadn't been anyone there to see her.

Her heart felt as if it was going to burst out of her chest, and she could feel a few drops of arousal rolling down the inner parts of her legs.

"Whew, alright Pinkie, you're almost there!" She mumbled, clutching her chest as she tried to slow her breathing. Unfortunately, she couldn't stay here for long, lest she arouses any suspicion from anyone watching the cameras.

Turning back, she quickly made her way down the aisle, again thankful for her luck as she was able to reach the end without being seen. The exit was a clear shot from here, but... even while sprinting, it would still leave her exposed for a few seconds. Once she got through those automatic glass doors, she'd be home free. Already, she could faintly see her car sitting in the mostly empty parking lot outside.

Taking a deep breath, she prepared for the final stretch. She could already imagine herself, a skimpily dressed pink girl sprinting for the exit, a huge bumpy protrusion hanging past her skirt and jiggling wildly with her every step. Her pussy quivered as the image was burned into her mind, begging for attention as the intensely aroused side of her mind secretly hoped that she'd be caught.

Then something wet brushed up against the back of her right leg.

"Eep!" Pinkie yelped, swirling around, expecting to find someone standing right behind her.

But rather than a person, she was instead met the curious muzzle of a familiar-looking pooch. It was a dog from her neighborhood, panting with its tongue out as it stared up at her excitedly, his tail wagging back and forth.

"W-wha?" Pinkie mumbled in confusion, looking back behind the dog as she notices that it was dragging around a leash that lay a few feet behind it.

"Sammy! Where are you, Sammy?!" A woman's voice called out from a few aisles down, likely the dog's owner. And she was getting closer. Turning back around, Pinkie peered out from the aisle again, biting her lip as she saw a few people had just entered the store.

She gasped as suddenly she felt a wet little nose shove itself up under her skirt as the dog investigated the odd smell that coming from this nervous girl's bulging underwear.

"No, no, bad doggy!" She whispered urgently, trying to push him away.

"Sammy? Where'd ya go, pup?" The woman called again, clearly from the next row over. She had to go now or else she'd be caught! But people were still around the exit doors!

The final straw was drawn as Pinkie heard footsteps rounding the corner at the other end of the aisle. With a burst of speed, she bolted for the exit of the store. She prayed that the dog wouldn't follow her as she stared straight ahead, feeling as if everyone around surely was staring right at her.

What was really only a few seconds felt like hours as Pinkie finally reached the automatic glass doors. Bouncing in place impatiently, she was forced to endure the roaring heat between her legs as she waited a couple of seconds for the doors to open. Her face felt so hot as she imagined every person in the store standing behind her, staring down at the evidence of her naughty deed.

The moment that the doors opened enough for her to fit through, she was gone, sprinting out into the parking lot at full throttle. She felt her already rapid breathing quicken as she found herself sprinting past a family who all looked at her oddly as she bolted past them. Pinkie didn't know if they noticed, but she felt like they had to have. Up ahead, she could see her car, parked partially behind a large pickup truck.

The moment she reached it, Pinkie ducked down between the two vehicles. Squatting behind the large truck, she finally took a moment to collect herself, heart thumping loudly in her ears as she panted as if she'd just run a marathon. It was over, she'd done it.

Had anyone really found out? She wasn't sure, but the heat and pleasure radiating outward from her crotch was almost too much to bear. Already a small clear puddle was forming beneath her as the front of her panties dripped with her juices. All the while, she could feel her mess balled up underneath her, the mental image this produced finally forcing her to drive both her hands down to start rapidly stroking her needy pussy.

"Ah~!" She inhaled sharply, her whole body trembling as her touch sent shockwaves of pleasure rippling from her clit.

She was already on the verge of cumming, but she'd need one last thing to finally push her over the edge. Standing up quickly, she leaned forward to pull open her car door, revealing the driver seat, pre-wrapped in a thin layer of clear plastic. Ducking down, she clambered carefully into her car, all the while keeping one hand pressed against her pussy, making her whole body spasm whenever the tip of one of her fingers grazed her inner lips.

Finally, she turned and slammed the car door shut behind herself, the noises of the outdoors immediately silencing as she was left with the intense heat of her own arousal. Her ass hovered almost a foot over the seat, the poop-filled protrusion in her panties hanging down towards it as if it knew what she was about to do.

Slowly, she began to ease herself down into the seat, gasping as she felt the peak of the bulge make contact. As she continued to sit down, she gasped as the densely packed poop inside her underwear start to squish and spread out from her weight coming down on it.

Soft poop began oozing out through the leg holes of her panties as the pressure grew to be too much for her underwear to handle, smearing her cheeks with brown filth. This proved to be the final straw for Pinkie, practically throwing her over her limit as she felt a massive rush of pleasure surge from her pussy.

"Aaah!" She cried out, biting her bottom lip hard as she rode the enormous pleasure high, convulsing as her hand continued to stroke and toy with her quivering pussy. Waves of intense pleasure continued to roll across her body, each one forcing a moan from Pinkie's strained lips. Eventually, the waves slowly grew less powerful until finally, she went limp in her messy seat.

Reclined in a pile of her own shit and wearing a thoroughly ruined pair of panties, Pinkie fell back against the headrest. That was easily the most intense orgasm she'd ever felt in her entire life.

"B-best... shopping t-trip... EVER!" She gasped, a broad smile spreading across her face as she bathed in the smelly afterglow stuffing her car.

She failed to notice a certain curious canine sniffing along the ground as it approached her car, it's owner scrambling after it as they approached the pink vehicle and its smelly inhabitant...
