Author's Notes:

CAUTION: This chapter was suggested by one of my Patrons by the name of QueenieChryssie, and is a prompt that involves a lot of intentionally gross content, which include slob-play, extreme diaper usage, and lots of other detailed parts that aren't for the faint of heart. Reader Discretion is strongly advised.

By the time the night came looming in from over the Equestrian horizons (and the two Discords finished creating a lot of chaos in the Netherlands), Twilight Sparkle was able to finish up all of her tasks and reconvene with Starlight and Sunburst. Fortunately for the Princess, Starlight didn’t seem too overwhelmed by her school counseling work, and was eager to get back to their research in the Surveillance Room again. Since Sunburst already informed her of his and Twilight’s successful findings earlier that day, the mood among all three of them was understandably high. So instead of wasting any time, the group made their way back to the hidden space after enjoying a quick dinner.

When the door to the Surveillance Room opened up, Sunburst was the first to enter while wiping his muzzle with a napkin. “Wow! I have to say, Princess, you made some really good stir-fry! I swear, I’ve never been able to get fried rice cooked that well myself.”

“Well, you can be sure to thank Spike for that,” noted the Alicorn as she and Starlight walked in tow behind the stallion. “He was the one who taught me most of the cooking skills I know.”

“Yeah, he really is great,” said Starlight in agreement, before she paused for a second and huffed in embarrassment. “Geeze, I can still remember how he acted when I tried to cook something in this castle for the first time. Even the garbage disposal had trouble holding it down!”

Twilight giggled from that reminder, and shook her head before glancing back at her protègè. “Yeah, I tried to warn you, remember? None of us liked that food back at your old village, but you were so insistent about how your own skills were better than Sugar Belle’s.”

Starlight sighed with a roll of her eyes, and tried to retort defensively with, “Well, I technically was before she got her cutie mark back! At least I tried to season that risotto I made.”

Sunburst looked back at the two while asking Starlight, “Wait, what did you season risotto with?”

The unicorn mare didn’t say anything, and just looked away from him with a notable blush on her muzzle. Meanwhile, Twilight chuckled to herself before answering for her. “She tried to use garlic powder and cinnamon.”

“Gah!” Sunburst couldn’t help laughing as he made his way towards that floating orb of blue magic. Unbenounced to any of them, there were already a couple prerecorded scenes of magic set in place with the aid of those mischievous Discords. But alas, that unfortunate detail wasn’t noticed by any of them as Sunburst gawked at his blushing friend. “Wow, really Starlight? Even I wouldn’t have tried that. And I once tried to make a ‘quesadilla’ with two frozen pizzas pressed against each other!”

“Hey, I did that too!” chirped Twilight with a giddy grin, before she quickly turned away from Starlight’s judgemental stare on her. “Uhhhh… heh heh heh… I had some bad snacking habits back when I was under Celestia’s teachings in Canterlot.”

Despite being slightly comforted by that relatable admission, Starlight still whinnied in annoyance while avoiding looking at either of her friends. “Well, I just want it to be known that I spent years out in that desert with nothing but a bunch of brainwashed ponies, and absolutely no way of knowing how to cook myself! And considering how I was able to actually make a risotto, that should say something about my abilities.”

“Trust me, Starlight,” said Twilight as she walked towards the couch, “what you made that night was not a risotto.”

While the Princess and Sunburst cracked up from that little quip, Starlight sat herself down on the couch with a bitter scowl and her forelegs crossed over her chest. Fortunately, while Sunburst gave that orb of magic a quick zap to activate its abilities, Twilight was quick to give her protègè an apologetic hug. “Sorry about that,” said the Princess with an honest shrug of her head, even though she had her sights set on Sunburst as he went to activate the surveillance spell’s alternate universe dimensions. “If it makes you feel any better, your cooking skills have improved greatly since you started living with us.”

Even though she appreciated that compliment, Starlight’s thankful smile was fairly weak as she nodded back at her. Luckily, since those swirling colors in the floating dome of magic were already growing brighter and moving about erratically, the group’s focus turned towards that while Sunburst sat himself down. Those colors slowly morphed to take the shape of that distinct white screen, and provided the three with their latest scene from an alternate world.

Or at least, that what they should have gotten. But instead, the ponies were met with a few seconds of greyish static reminiscent of an old television. After that, a monotone beep lingered on as a blank picture appeared over the screen, showing a cartoonish caricature of Discord while pouting and holding a broken vase. The caption underneath read in a bold font, ‘We are currently experiencing technical difficulties. Please wait for the next Alternate Universe scene.’

“Ugh!” Starlight threw her head back with a frustrated groan, while the other two sighed with their hooves over their faces. “Why am I not surprised Discord would pull something like this?!”

“Hmmmm…” Even though he was equally as peeved as his friend, Sunburst ended up humming curiously while brushing his goatee with a hoof. “Are we sure that this is our world’s version of Discord? I mean, we know there are alternate interpretations of us, so who’s to say he wouldn’t have alternates as well?”

Upon recalling that one scene she had witnessed alongside their Discord, Twilight grew wide-eyed as she looked back at the screen as well. “Actually… I think that might be the cas--”

“Oopsie!” shouted Discord’s voice in a sing-song tone through the magic screen. That still image the three were seeing was suddenly pulled away, revealing it to be a poster board that the Alternate Discord had placed over their point of view. “Sorry about that,” he said while grinning widely through the screen towards his viewers. “I just had to set up this scene correctly for the sake of your ‘research’~”

With the card pulled away, it was revealed that the setting happened to be outside of Fluttershy’s cottage; more specifically, Discord was standing out by the mud-pit where Fluttershy kept her pigs. Unfortunately, the three ponies watching through the magic feed weren’t able to see any pigs, or Fluttershy herself anywhere in the scene. Instead, the three were met with that universe’s version of the chaotic draconequus, who happened to be standing in front of some unrecognizable pinkish blob that was moving a little behind him. “Now, I’ve been informed by your dimension’s version of me that you three are conducting some… voyeuristic surveillance on your nation’s subjects for the sake of seeing examples of Friendship, correct?~”

Twilight’s head slumped down as she covered her face with both hooves, and she groaned hard in response to that question. Even though the scene itself was previously recorded elsewhere, the Princess had no way of knowing that as she answered the draconequus on screen. “Ughhh… You know, you don’t have to word it like that, Discord…”

Unfortunately, Sunburst and Starlight looked back at each other and shrugged silently, neither of them being able to argue against Discord’s accurate description of their experiments.

“Well, in that case,” said the draconequus, who clearly predicted that he would be able to give a well-timed response to the Princess’ answer, “allow me to assist you in your endeavours, and provide you a wonderful friendship lesson myself! For this lovely scene, I’d like to present to you three…”

The moment Discord stepped aside to reveal what was lumbering behind him, all three of the ponies gasped in absolute shock. Meanwhile, the draconequus continued his presentation as he said cheerfully, “Behold! Here’s what happens when a naughty pony tries to lie!~”

Pinkie Pie -- or more specifically, the bloated mass of cellulite-stuffed flesh that used to be Pinkie Pie -- was sprawled out across most of the pig pen with a dreamily intoxicated smile on her fat-swollen face. Twilight cupped her hooves over her mouth in terror, looking absolutely appalled at how slobbishly piggish that Alternate Discord had corrupted his universe’s version of her friend. Most of the bottom half of her bulbous, cottage cheese-like body was covered in mud, while the parts that showed her pink fur were riddled in nasty pustules of bulging zits. Thick droplets of sweat were constantly oozing down her fat rolls, which only made her swollen pimples grow oilier and risk popping randomly. Of course, despite how disturbingly gross the poor mare may have looked on the front, the three stunned ponies couldn’t look away from Pinkie’s backside; it almost looked like an oversized bean-bag chair was tied around the pony’s swollen waist, but the giant white garment was easy to guess given the massive staining of brown that took up most of the bulging and lumpy shape.

“Ugh!” Starlight turned away from the screen and heaved a little, luckily not throwing up anything just yet. Meanwhile, Sunburst could only gawk at the screen with his jaw dropped and quivering, and his face paled in disgust. Twilight couldn’t even look at the scene, and had her head perched low between her legs to keep from looking up. But through that magical screen, Discord was still grinning as giddily as ever while presenting the unholy abomination he created for their viewing.

“For you see,” began the draconequus in a casually cheeky tone, while an oversized clothespin was tightly clamped over his nose. “I decided to try a little experiment of my own to establish the importance of being honest, and how badly things could end up for somepony if they keep lying. For example…”

Despite how horribly Pinkie Pie must’ve smelt, the mare didn’t seem the slightest bit fazed while giggling with piggish snorts between her forced breaths. The pony tried to hop around, but her pudgy legs were hopelessly hanging from the sides of her bloated form to keep her from moving from the pen. And even if she was able to move, it was doubtful she could go very far while wearing that obscenely heavy diaper that was bulging from her excrement. But even with all of those horrible things shown through the screen, Discord still leaned in close to Pinkie’s sweaty and zit-ridden face to ask sweetly, “Oh, Pinkie Pie?~ Tell me the truth… did you go poopie in your diaper again?~”

That question caused Twilight to nearly gag from how optimistically the draconequus asked it, almost like he was caring for an unruly child. Of course, given what Pinkie was wearing, that comparison may have not been too inaccurate. Since both of the mares on the other side of the screen were trying their hardest to ignore the scene, only Sunburst was watching with a mortified look as the bloated Pinkie shook her head with a giggle. “Hehehehe--SNORT!! N-N-Noooooooo~”

Without warning, the mare’s poofy tail flagged right up, and a violently loud eruption of bubbling, oozing gas could be heard as the back of that diaper bloated out even more.

BBBBLLRRRRRRRTTTTTTT!!!~

“UGHHH!!!” Sunburst finally threw the back of his cape over his head, and he tried his hardest to clench his eyes and unsee that horrifying result of Pinkie’s lie. The massive expulsion of her thick, rancid mess stretched the rear of her diaper out even further than it already was. The brown staining against her white fabric deepened even more than it was before, and the lumpy mass expanded out to reach closer to the back of that pig pen. And during that lengthy moment of disgusting exhibitonism, Pinkie’s eyes were clenched shut while giggling like the brainwashed buffoon Discord made her.

“Whoooo!!~” Discord pulled himself away from the rancid pony, and fanned his face with a claw while chuckling in delight. “I must say! You’d think that after the countless chances I gave her, that she would understand the correlation between that and her little white lies!”

The draconequus then looked back at the screen with a shit-eating grin, and added, “Or should I say, her rather large brown lies~ Heh heh heh…”

“Discord,” muttered Twilight venomously through her hooves while she was still perched with her head pointing to the floor, “I swear to Celestia if you don’t stop this RIGHT NOW--”

“Hmmmmmmm~” Discord’s audible hum interrupted the Princess’ warning threat, and he continued staring through the screen while tapping the bottom of his chin. Sunburst tried to get up and make a beeline for the door, but he yelped in horror when he saw that a large cartoonish lock was bolted to the knob. Starlight tried to teleport out of the room, but her flash of magic only resulted in her falling back onto the couch exactly where she was. Twilight tried the same, and was met with the exact same outcome as her friend. Even with how frustrated and panicked the ponies were getting, none of them even tried to look back at that screen as they heard Discord say evilly, “Perhaps we should ask her again~”

Despite the trip of horrified “No’s” that echoed direly through the other end of that magic feed, the draconequus was grinning from ear to ear as he got back up towards that swollen mass of pure revulsion. Even though the stench permeating off of Pinkie was making the space around her ripple like she was under heat, the brainwashed mare was still giggling sweetly while blushing through her zits. The moment Discord got up close to her once more, an especially nasty bulb of acne right atop the mare’s forehead broke open. A thick glob of yellow puss landed right atop Discord’s forehead, but he didn’t even flinch while grinning down at his creation. Instead, the draconequus swiped up that disgusting pustule with his talon, and gave it an unnecessary lick with his tongue before asking, “Hmmmm… So, Pinkie Pie… Did you make another poopie in your diaper?~”

“Hehehehehehe! N-Nooooooo!~” Pinkie gave Discord another firm shake of her head while smiling giddily, with her sweat-matted mane flapping against the sides of her face and dripping incessantly. Of course, it was hard to focus on the mare’s front as another violent eruption caused the rear of her diaper to swell out once again.

PPPPRRRRRRRTTTTTTTT!!!~

That mass of browned, lumpy padding bulged out even further, and the grotesque pony shivered as her hooves curled up from the too-familiar sensation. Pinkie let out a relieved-sounding moan while filling up her diaper like it was nothing, not seeming to mind that revolting stench at all. And while that disgusting example of the diaper’s elasticity was being displayed on the screen, Starlight and Sunburst had to cover their faces like they were avoiding the sight of a nuclear blast. All three of the ponies were struggling not to gag from the unsettling display Discord was laying out, but Twilight had enough composure to scream at the pre-recorded scene, “DISCORD, YOU BETTER STOP THIS RIGHT NOW!!!”

“Oh, does this upset you, Twilight?~” asked the Alternate Discord while leaning his face back into the screen with a smug grin. “But I thought you wanted to see ponies out in their natural environments to better learn friendship. Isn’t this a fair example on why ponies shouldn’t lie?~”

Even though the draconequus was displaying the scene from a different dimension, the bloodthirsty glare that Twilight was shooting him through the screen was as intense as when she battled with Lord Tirek. Of course, since that Discord wasn’t able to see her reaction due to technically not being present, his shit-eating grin remain unfaltered in the slightest. In fact, the draconequus’ smile widened even more before he pulled away from the magic feed, and revealed something even more disturbing than Pinkie Pie’s horrifyingly bloated state:

A giant multi-story ladder meant for an Olympic-sized swimming pool was now perched above the pig pen. And at the very top of it was a diving ladder, which had that universe’s version of Princess Twilight standing on it with a mindlessly wide smile.

The Twilight on the other end of the feed gasped with her hooves over her mouth, and she reeled back from the screen while hearing Discord’s maniacal laughter.

“Ooooooh, this’ll be a fun thing to see!~” Discord then panned the magic feed back, which gave the group watching a full view of how high the Princess was perched above her disgustingly slobbish friend. Even with the Alternate Twilight’s wings being seen flapping excitedly, there was no doubt that any jump she made would send her falling straight down on top of that oversized padding. And down below on the ground, Discord was peering up at her while holding a cartoonishly large pair of binoculars.

The Twilight on the other end of the screen had her eyes as wide as dinner plates, and she was quick to throw her hooves up and light up her horn. “NOOOOOOOOPE!! Nooooooo, no no no no no no no no, NO!!!”

“Oh, yes, your Highness!~” cooed Discord on the other end of the magic feed. However, his childishly wide grin was still pointed up at the top of that diving board, just as the Alternate Twilight began to hop up and down in preparation. “It looks like we’re going to see a fantastic dive from the lovely Princess up above!~”

Beside the Alternate Discord was a long judge’s table, with three identical copies of himself seated to give their scores for the Alicorn’s jump. Meanwhile, the mindlessly smiling mare up above didn’t seem to care that a giant mound of fat and unmentionable excrement was waiting below her, and she made one last jump before hopping off the diving board. Discord was grinning ear to ear while watching through his binoculars, and he followed the Princess’ descent as she seamlessly soared down to the ground below. The Princess gave several impressive flips during her descent, which gartered some impressed hums from the judges. “Ooooh!” cooed the draconequus excitedly. “Here it co--”

ZAP!!!

Twilight Sparkle’s magic blasted the base of that orb of magic with a strong surge of electrifying, bright blue energy. The entire room shook under Starlight and Sunburst’s hooves, and the two nearly fell to the ground while the lights flickered all around. Twilight’s teeth were gritted in focus as she let out a profoundly strained groan, and encapsulated the entirety of tht orb within her aura of lavender magic. Despite how massive and powerful that containment of surveillance magic may have been, Twilight was able to lift it up high with her magic as she continued to groan, and that screen pointing at her started to flicker like a television with bad reception. And just as the Princess in that scene was about to make her ungodly landing, a superb surge of white light blasted from Twilight’s horn, and sent a surging pulsation of her magic across the orb to wipe the screen clean.

“Aaaaahhhhhhhhh….” Twilight’s eyes clenched shut while her body twitched from the amount of overexertion that spell took from her. With a profoundly relieved sigh, the Alicorn lowered the magical orb back down, which was still able to float on its own the moment Twilight released it from her own aura. The Princess slumped back on the couch with a defeated expression on her face, but still smiled when she saw that the surveillance magic was still glowing brightly with its colors swirling continuously. The scene may have been cut before it had a chance to end, but it was obvious that none of the ponies were upset in the slightest.

Since Twilight was sprawled across the couch and panting in exhaustion, Starlight went up to the floating orb to retrieve the recorded scene and destroy it herself. Meanwhile, Sunburst went over to the Princess with a concerned look of panic on his face. “T-Twilight! Are you alright?!”

Despite how wiped-out that surge of magic left her, with the tip of her horn sizzling a little with a plume of smoke stemming from the top, Twilight was able to nod with a gracious smile on her face. “Y-Yeah, I… I think I’ll be okay...”

After taking a couple more heavy breaths, the Princess got herself up so she could walk out of the room instead of teleporting. Fortunately, the oversized lock that the Alternate Discord placed on their door was gone, and she was able to exit the Surveillance Room without any issue. “I… I think I need to lie down for a little bit…”

Neither of the unicorns tried to stop her, and only nodded sympathetically while waving her goodbye. Luckily for the sake of all of their sanities, it didn’t seem like that draconequus’ presence was evident anywhere else by the time the moment fully died down. Starlight and Sunburst looked back at each other worriedly, but neither of them tried to say anything in response to what they just witnessed. With any hope, Twilight would be alright with trying a memory-wipe spell of some kind when she got her energy back up, just in case the things they saw became too damning to look past.

Sunburst was blushing fairly hard as he looked between Starlight and the floating orb, his muzzle skewed worriedly as he carried a look of contemplation. Starlight seemed equally as unnerved, but her muzzle remained tightly shut while looking between him and the orb as well. After what felt like an eternity of silence, Starlight was the first to speak up after giving a sharp huff through her nostrils. “Well, ummm… do you think that Discord had anything else done to this thing?”

Sunburst shrugged uncomfortably, and said back to her, “Well, ummm… if Twilight’s assumption that it was a different Discord from our own is correct, then… maybe it was just that scene he would intrude on?”

Starlight sighed with an affirming nod, but still seemed wary as she glanced back at the dome of blue magic. “Well… I certainly hope that’s the case…”

After another moment in thought, the mare closed her eyes before saying with a fretful sigh, “Although… maybe we should watch another Alternate Universe scene without her present? I mean… just in case he had something else planned involving her, you know?”

Sunburst looked just as worrisome about that idea as she did, but he still took a breath before nodding his head in agreement. “Honestly, I… I can’t say I’m against that idea. I mean… as long as Twilight doesn’t get involved like she had with this.” He motioned around the Surveillance Room itself, not needing to remind his friend of what just transpired a few minutes prior.

“Yeah, that’s what I was thinking.” With that, Starlight Glimmer sat back down on the couch, as did Sunburst without much hesitation. “Sooooo… if it’s something inappropriate, we dispose of it and not tell Twilight about it?”

“Agreed,” said Sunburst with a soft smile back at her, before the two shook hooves in agreement. After Starlight made sure that the door behind them was firmly locked again, she turned her attention back to the floating orb of magic alongside her friend. And with a joint effort of both of their illuminating horns, the two unicorns were quick to not only reactivate the dome’s surveillance magic, but also to input the Alternate Dimension settings with the best of ease.

Unfortunately, despite Twilight Sparkle’s efforts to cleanse the orb earlier, the Alternate Discord’s other prerecorded scene was still in place, and was quick to be activated as the next scene commenced without fail...
