Spoiled Rich may have had quite a reputation around town for her bad habits, but Princess Twilight was the only one willing to put her in her place. Unfortunately, her method of punishment might be a bit much for Spoiled to handle...

Spoiled Rich, wife of the wealthy entrepreneur Filthy Rich, was no stranger to being in the spotlight. Whether it was for positive reasons or otherwise, the mare relished being the center of attention if it meant having control. And over the years, Spoiled made sure to build up quite a reputation for herself as the head of Ponyville's PTA, as well as a participant for other community and charity events.

Unfortunately for Spoiled Rich, it seemed that a certain Princess was keen enough to notice the many, many discrepancies in the mare's personal records. In most instances, Twilight Sparkle wouldn't have hesitated to prosecute the mare for her countless offenses. However, despite how justified it would've been to go the legal route, Twilight decided to enact a more... unorthodox method to teach Spoiled Rich a lesson.

More specifically, Spoiled Rich would learn the consequences of actually having no control.

Chapter One

“Ummm… Hello? Princess Twilight Sparkle?”

Despite how triumphantly the castle doors opened at the front, the grand space was eerily dark due to how early it was. The sun hadn’t risen yet, so only the candlelights within the Castle of Friendship’s main entryway served as a source of illumination. An older pink mare cautiously entered the castle with a look of apprehension, unsure of whether or not it was alright to arrive so early. She sighed tiredly and rubbed her eyes with a hoof. “Ughh… this notice better be important…”

-SLAM!!!-

“EEP!!” The mare shrieked and leapt off the floor for a moment, right as the doors behind her slammed shut. She looked back wide-eyed in a panic, but a large metal chain had already wrapped around the handles to ensure she couldn’t leave. Her blue eyes widened in worry, as if she just found herself inside of a stereotypical haunted castle. Just as she was about to hyperventilate, a familiar voice from up above caught her attention:

“Spoiled Rich?”

“AAAHHH!!” Spoiled jolted up again, and turned around to stare up at the grand banister overlooking the room. Princess Twilight Sparkle stood at the top of the spacious twin steps, the candlelight illuminating her like a vampire being introduced in a horror story. Spoiled tried to keep a gracious smile, but was obviously nervous when she was met with a firm and unrelenting stare from above. The Alicorn took her time as she walked down the stairs by herself, obviously choosing to meet with the mare alone.

“I take it that you received my letter, Mrs. Rich?” Twilight didn’t look down at her as she descended down the stairs. Regardless, Spoiled Rich bit her lip in trepidation before nodding her head.

“Ummm… yes, I have?” She looked a little annoyed as she pulled the parchment out from her blouse. She took a moment to read the notice while Twilight made her way down the stairs:

Dear Spoiled Rich,
A very important issue has come to my attention, which involves your presence at the Castle of Friendship at 5a.m. sharp. For your personal sake, I would prefer that you come alone. After our discussion, I promise I’ll leave you to continue any errands you already have planned for the day.
-Princess Twilight Sparkle

Her muzzle wrinkled from how vague and uninformative the letter was, especially considering how studious and detailed Princess Twilight’s letters usually were. Nevertheless, Spoiled sighed and rolled her eyes as she tucked the letter back in her shirt. “So… would you mind telling me what this is about? I usually don’t wake up this early, you know!”

Spoiled knew it was inappropriate to be so pert with ponies, especially a Princess, but having to wake up at 4:30 in the morning wasn’t exactly an appropriate request. But instead of being given an answer, Spoiled Rich was surprised to see the Alicorn walk right past her with her horn lit. “Follow me,” stated Twilight in a surprisingly cold tone, while her lavender magic illuminated the way for Spoiled to follow. The mare paused for a brief moment in contemplation, but breathed out with a flat look on her face. She awkwardly followed the Princess out of the main room of the castle, and down a spacious hallway towards one of the ground floor studies.

Spoiled tried not to look around the lavish abode, which was easier than expected due to how dark the castle was. She had to wonder where Twilight’s little lizard pet went, but she could only assume he was either still asleep or back in Canterlot. Twilight’s glowing horn led the way into a comfy little office, where a desk and two chairs were already set up for them. Twilight sat down in the plush office chair behind a desk, and her horn remained lit to open up a couple drawers. Spoiled Rich silently sat down on the more modest chair across from the Princess.

“Now, before we begin this session…” Twilight looked around the room briefly, and used her magic to light up some more candles and give the office a somewhat comforting glow. She even lit up the fireplace with a flash of her aura, before turning her focus back towards Spoiled Rich. “... I’m going to give you the benefit of a doubt, and allow you a single opportunity to atone for your actions.”

Spoiled’s eyes widened in surprise, before shooting the Princess an offended look. “E… E-Excuse me?!”

“Do not test me.”

The mare let out a silent gasp and reeled her head back, acting like the Princess’ slightly firm voice was akin to being spat in the face. “What the!? P-Princess, this is HIGHLY inappropriate behavior! Especially this early! Do you have ANY idea who I am?!”

Twilight huffed in annoyance, her flat expression growing more miffed. “I suppose I should’ve expected that kind of reaction…” She then floated out a large manilla envelope in her aura, and placed it on the desk. “Nevertheless, considering what I have on you, I don’t expect you to say I didn’t warn you, Mrs. Rich. I gave you the opportunity to be honest with me.”

“H-Honest with you about WHAT?!” By that point, Spoiled Rich was just looking pissed. “Twilight, what the HECK is this all about?! Why did you have to wake me up in the middle of the night, and have me come all the way out here by myself!? Was this just to… to berate me or something?!?”

“No, I haven’t.” Twilight’s tone was growing as cold as her unamused glare on the older mare. She then opened up her envelope, and pulled out one of the documents inside. “And to answer your question, I indeed DO know who you are, Spoiled Rich. You’re a member of the Ponyville School Board and PTA, am I correct?”

Spoiled Rich paused and stared at her for a moment, blinking a couple times before nodding. “Ummm… Yes?”

“Then maybe you can explain this to me…” Twilight floated the document onto the desk, but remained leaned back in her chair in wait. Spoiled leaned in to inspect the paper, but her face paled the moment she recognized the itemized form. Her eyes widened, and her pupils shrunk for a split-second. When she looked back up at Twilight, her firm voice carried an obvious hint of fear. “Wh… W-Where did you get this?”

“Get what?” asked Twilight with her head tilted. “Do you mean the school’s annual budget forms that you blatantly forged for your own benefit? You are aware that I can acquire many forms like these as Princess, right?”

She then picked the document back up, and read some of the highlighted sections out-loud to make Spoiled squirm in her seat. “Last month, over five thousand bits weren’t counted from the charity drive where over twice that was donated by Ponyville citizens. If I recall correctly, you had purchased a necklace valued around that amount shortly after the event…”

Spoiled Rich crumpled a little in her seat, although she tried her best to keep her face frozen before the Princess. Meanwhile, Twilight just kept reading. “And in this budget form, your lunch and dinner expenses were over quadruple any of the other PTA members or school staff. Not to mention, there are many sections in the forms I collected where edits were obviously made with white-out, and somepony else’s name written down in your place…”

She floated out several of the other documents and receipts, while a strong aura of her magic made sure to latch Spoiled’s hooves to the legs of her chair. The mare yelped out, but she was helplessly trapped before the increasingly pissed Princess. “You even overinflated the estimated budget for necessary school repairs, only to CANCEL said repairs in Cheerilee’s name before pocketing all the money yourself! Mrs. Rich, do you have ANY idea how many federal laws I have proof of you breaking?!”

Spoiled tried to avert her eyes from Twilight’s glare, but she could only bite her lip while met with so much damning evidence in the Princess’ aura. “... uhhhh… I… I don’t know what you’re talking about?”

“Spoiled Rich, no matter how much you try to deny things, this folder alone has more evidence than you’re able to talk your way out of.” Twilight showed what looked to be a couple inches worth of papers that were tightly stacked in her magic. She ruffled through them while glaring more intensely at the writhing mare. “Thousands… upon THOUSANDS of bits were depleted from the school budget, various town-organized charities, and even your own husband’s donations without his knowledge! And before you try to say otherwise, I have photographs from the Ponyville bank confirming that YOU were the one who made these withdrawals!”

She then tossed several high-quality pictures from the bank’s security camera, which showed Spoiled Rich clear as day strolling into the bank with a checkbook, and coming out with large bags of bits. Spoiled Rich may have been trapped in her seat, but she was left frozen in shock. Her muzzle hung open for a moment, unsure whether or not this was meant to be an interrogation or a setup for a major sting. Regardless, the older mare tried to smile nervously back up at her livid stare. “Uhhh… heh heh heh… it… i-it must’ve… been a changeling?”

Twilight just sighed with a very unamused look. “Oh, really now? Is this ‘changeling’ also the one using your husband’s business to solicit other stallions around town?”

“WHAT?!” Spoiled nearly fell back in her chair from that reveal. “H-How do you know about that?!”

Twilight huffed with a smug little smirk. “Well, thanks for confirming it with that answer alone. But since you asked…”

More pictures were pulled out of the folder through her magic, and laid out across the desk for Spoiled Rich to gawk at. All of them were from the exact same position outside Filthy Rich’s business, clearly after-hours as evidenced by the clock shown through the store’s window. Each photograph was nearly identical, with Spoiled Rich opening the door to either invite somepony in or wave them goodbye. The only major differences were the dozen or so stallions shown in each photograph, as well as the disheveled look Spoiled had on her face as she let them leave with a satisfied grin on her face.

Spoiled Rich’s face had now turned ghost-white, while her purple mane became straight and hung down heavily. Twilight didn’t say a word for a moment, and just marveled at the mare’s stunned expression with a waiting smile. After what felt like hours of deeply uncomfortable silence, Spoiled Rich’s eyes closed before she hung her head in shame. Despite the various excuses that could’ve come to her head, she knew that she was caught with her hoof in the cookie jar. Her career, her wealth, her reputation, and even her marriage were all on the brink of jeopardy because of the Princess sitting before her.

“... Okay,” she muttered under her breath in absolute shame. “... you win.”

“Oh, no,” clarified Twilight as she tilted her head, and shot the mare a cheekier smirk. “I don’t believe you understand Mrs. Rich. I didn’t ‘win’ in this scenario. At least, not yet~”

Spoiled Rich threw her head back up, her reddening eyes wide-open in surprise. “W-What?”

“If you allow me to explain…” Twilight finally pulled herself from her seat, leaving all her evidence on the desk as she walked around it to better face her captive mare. “Spoiled Rich, given all that I learned about you and your exploits, I would want nothing more than to take you to the proper authorities, and have you held accountable for your deplorable actions…”

As she walked behind the bound mare, Spoiled’s muzzle scrunched in confusion while trying to turn her head. “... but?” she tried to guess.

“But, given my standing as Princess, as well as my close friendship with your husband, I wanted to try my own method of punishment that won’t completely break his heart.” Twilight walked around the mare completely before facing her once more, this time with a slightly sympathetic smile that made Spoiled even more worried. “And if you agree to comply with my method of discipline, I’ll consider it a fair alternative to whatever Ponyville’s authorities might impose.”

Her eyes widened in shock, not expecting for the Princess to issue such an ultimatum. While she may have been rightfully unsure about what to expect, the last thing she wanted to do was deal with major fraud charges. Not to mention, Spoiled still kinda loved her husband enough to avoid being divorced by him. So despite the apprehensions and red flags going off in her head, she took a deep breath before accepting the Princess’ offer. “Ummm… W-Well, I… I’m willing to hear you out then… Your Highness.” She even shot Twilight a fake smile to show her graciousness.

“Oh, you don’t have to be so formal with me…” Twilight let go of the magical grip she had on Spoiled Rich’s hooves. “Besides, I have a feeling you’ll learn your lesson pretty quick with the punishment I have planned~”

Spoiled Rich remained in her chair for a moment, but her smile weakened immensely when she saw the peculiar grin Twilight had. She squirmed in her seat a little, her cheeks blushing from the realization that she was still alone with this Princess in the middle of the night. “W… What… W-What kind of punishment were you thinking?”

“Oh, it’s just a simple piece of attire I learned about in some history books…” Twilight walked away from the mare to head for one of her massive bookcases. She pulled out a particularly old, dusty book that looked to have King Sombra’s insignia engraved on the leather binding. “I actually found this in the Crystal Empire after my friends and I helped reclaim it for my brother. This book was actually printed before Sombra went insane from Dark Magic, so I would consider this fair for my research.”

Spoiled Rich wasn’t too keen to hear where this was going. While Twilight scanned through the brittle pages for her place, Spoiled tried to slowly lift herself up from her seat. As soon as she got her hooves back on the floor, the scared mare carefully walked backwards towards the office’ doorway. Unfortunately, she could only take two or three steps before a new aura of magic tightly clasped her hooves to the floor. Twilight’s horn was lit up a little brighter, while her muzzle grew a more devious smirk.

“Aha! Here we go…” She peered in closer to read the ancient Ponish and double-check its legibility. “A spell developed by King Sombra himself… Public Indecency Nullification~”

“P-Public WHAT?!” Spoiled thrashed a little against the magic holding her in place, but it was obviously to no avail. Despite how badly she was starting to panic, the mare was no match for a skilled Alicorn’s magic. The Princess turned back towards her, not paying any heed to her protests as she walked up casually. “W-W-Wait! Twilight, please! It… I-It was just a mistake! Y-Your Highness, you have to believe me! I promise I won--GAHHHH!!”

That magic binding her hooves moved upward, and grabbed hold of the bare’s backside. Her tail was abruptly lifted up, exposing her bare nethers for a brief moment while Twilight was grinning. Spoiled Rich shrieked and spasmed against the aura, even as the lavender magic glowed more brightly around her waist and hips. Twilight closed her eyes for a moment, and pointed her horn directly at the mare to leave her in a panic. “Oh, no… T-Twilight, please NO!!”

-ZAP!!!-

With a bright flash of magic, Twilight hit her mark directly. The surge of magic struck that highlighted aura around Spoiled’s backside, turning the translucent glow into a physical shape that took form around her waist. The mare didn’t feel anything at first, leaving her to assume that the Princess could’ve possibly missed that shot. However, after freezing for a second or two with her eyes clenched shut, she slowly reopened them before glancing back at her rump. As soon as she saw what was latched onto her, she gasped in absolute horror. Her mouth hung wide-open, while her pupils once again shrunk at the sight of a steel belt tightly clasped around her hips and privates. “WHAT THE?!”

“Hehehehehe~” Twilight was standing behind the mare at that point, and giggled when she admired her handiwork. “My goodness, it seems that my chastity belt spell worked exactly as expected!”

“C-C-CHASTITY BELT?!” Spoiled Rich did a couple spins to try and get a better look at the metallic belt. The item looked to be one single piece, without any moving parts to emphasize its overall strength. Heck, considering how snugly it was latched around her waist and hips, anypony would’ve assumed it had to be welded onto the mare if it wasn’t magically conjured. Right over Spoiled’s marehood was a large golden emblem, which appeared to be a sturdy lock behind a keyhole akin to something from an antique door. Unfortunately, considering how small the keyhole itself actually was, Spoiled wasn’t sure if it could even be picked open.

Spoiled had to lie on her back, her legs ungracefully spread apart to even get a good look at the belt. Her expression was nothing short of mortified, especially when Twilight had to cover her muzzle from the precarious pose her captive pony was in. “... oh Goddess,” muttered Spoiled with a growing look of dread on her face. “Oh Goddess, this can’t be happening.”

“Well, think of it like this…” Twilight used her magic to house the mare back onto her trembling hooves. “As long as you last a week with that belt on, I’ll cons--”

“A WEEK?!?” Spoiled Rich’s panic instantly turned to furious anger. She stormed right up towards the smirking Princess with a livid snarl. “YOU PERVERTED LITTLE BITCH, UNDO THIS RIGHT NO--”

-BZZZZZZZT!!!-

“EEEEPPPP!!!” With just a single zap of Twilight’s horn, which struck the belt’s keyhole directly, Spoiled Rich fell to the floor with her rump and tail raised high. She let out a harsh, lumbering moan while convulsing on the floor. That belt around her waist buzzed rather loudly against her nethers, instantly tingling her marehood in a way her hitachi wand back home never could. She felt like an industrial-strength motor was turned on between her legs, right up against her unexpecting clit. She wasn’t sure what in Equestria’s name Twilight did to her, but the buzzing continued on after the Princess turned off her horn. Meanwhile, Spoiled Rich was left writhing on the floor, with her hooves curled up tightly, and her teeth gritting in an attempt to muffle her overwhelmed moans. “MmmmmMMMMMmmnnnghhhh…”

“Hehehehehe~” Twilight just giggled with a hoof over her muzzle, and stood behind the mare’s presented stance with a perverted blush. While it may have been extremely inappropriate, her punishment felt the tiniest bit vindicated in the case of Spoiled Rich. Nevertheless, the Princess made sure to take a couple steps back while Spoiled was quivering on the ground. “What’s the matter, Mrs. Rich? Considering how many of Ponyville’s stallions you serviced behind your husband’s back, I would’ve figured you’d appreciate feeling that kind of titillation all day~”

“AaaaaAAAAHHH!!!~” Spoiled Rich tried her hardest to get back on her hooves, but the surging waves of magic coursing through her nerves was leaving her knees wobbling like gelatin. If she was able to glance back at that enchanted belt, she likely would’ve seen the bright purplish glow of manic emanating from the keyhole in the middle. Unfortunately, Spoiled was obviously too overwhelmed by the constant pulsations from that belt, which seemed to focus directly on the most sensitive parts of her marehood. She could already feel herself winking repeatedly, and there was no doubt that she was going to soak through that belt if those tantalizing surges didn’t let up soon.

“NNNNFFFF!!!” After nearly a minute of groaning and stumbling beneath her own weight, Spoiled Rich was able to miraculously stand on all fours somewhat competently. But alas, her shaky posture was exacerbated by her knees continuing to tremble from the belt’s incessant buzzing. Her head suddenly lurched down in an attempt to stifle a moan, but the giggling Princess could still hear how badly she was straining already. Spoiled had to bite down on one of her hooves as she whimpered shakily. “Mnnnnghhh… Ohgoshohgoshohgosh…”

“Oh gosh indeed!” Twilight had to fan her face with a hoof while getting a prime view of the mare from behind. Spoiled’s purple tail was still lifted high out of instinct, although that belt did wonders for concealing her arousal from view. The metal garment certainly stood out like a sore hoof, but it didn’t seem to affect the mare’s gait too badly. If anything, the biggest concern Spoiled would have to endure would be leaking herself. After only a couple minutes of the belt’s effects, Twilight could already see the fur along the sides of that crotch-lock beginning to dampen from Spoiled’s pussy getting riled up. That made the Princess smirk with a more mischievous look while tapping her chin. “Hmmmmm…”

“Wha… W-What the FUCK is wrong with you!?! NNNNFFFF!!~” As soon as she belted out that expletive, an especially sharp surge of magic hit Spoiled Rich right against her needy clit. The mare nearly fell to the floor from how brutally that wave of titillation struck her nethers. She had to hold onto the side of the desk while her knees buckled, and her voice came out in a shakier groan. “OoooOOOooohhh~”

“You know what? Wait right there, and I’ll be back in a minute.” Twilight casually left the office without any concern in her voice. Spoiled was panting like a mare in heat while hugging the desk, unsure whether to beg for mercy or chase Twilight down for a beating. It took her a moment to realize the Princess left the room, not that she could’ve given much of a response while convulsing on the desk. After panting out several rapid breaths, she finally managed to stumble away from the desk and waddle towards the doorway.

“Aaahhh!!~” Spoiled Rich fumbled with every other step, her breaths coming out in cute little moans more akin to something heard from an X-Rated film. She wasn’t sure how long she was left alone, but she could barely walk a quarter of the way down the hall while her legs were tingling all over. Her face was already getting as red as a tomato, with beads of sweat appearing on her forehead. She wasn’t sure where she could go, or even how she could function for the rest of the day; but at the same time, Spoiled knew that she had to leave this place before that pervert tried anything el--

“Oh, there you are! Don’t worry, I’m not going to let you leave with that thing showing~”

Spoiled tried to freeze up in a panic, but that buzzing belt kept her shivering with a bitten lip. The mare was standing somewhat-still, but had to lean against the wall while shuddering with a heavy groan. Her tail was flicking back and forth, and that belt’s buzzing was causing her hips to buckle back and forth involuntarily. Twilight Sparkle didn’t seem the slightest bit fazed, and walked up from behind with a couple items floating in her aura.

“First of all, I have a pair of fitness shorts here to cover up your belt. I even had it specially made so it won’t show the bulge of your belt, so you won’t have to worry about getting too many stares.” Twilight smiled while showing off the black spandex shorts hovering in her magic. Of course, when Spoiled tried to turn around with a livid glare, her eyes shot wide-open the instant she saw what else was in the Princess’ aura. Her sharp gasp seemed to make Twilight’s eyes narrow on her more devilishly, and she took that moment to present the other garment in her magic.

“Oh, and since you’re already getting wet in that thing…” Twilight tried not to snicker while showing Spoiled Rich the white, frilly piece of plastic padding. “I was lucky enough to keep a few of these training shorts from when Spike was learning to use the potty. They’re not full-fledged diapers, but I’m sure they’ll be effective enough to protect you from leaking~”

Spoiled’s jaw dropped to the floor. Unfortunately, her attempt to be stunned speechless was accompanied by a long, shivering moan that escaped her open maw. “Mmmnnnghhhhhh~”

“Good to know you approve.” Before Spoiled could try to defend herself, Twilight kept a chipper smile as she lit up her horn and grabbed hold of Spoiled’s flailing legs. The mare yelped out in a panic, but was helplessly pinned in place while Twilight pulled her hind-legs through the holes of the training shorts. The thin padding slid up with relative ease, completely covering the buzzing belt so the mare’s rump and nethers were hidden behind the plastic. Twilight then got the spandex shorts in place, which thankfully covered the padding completely.

By the time her legs were let go, it merely appeared that Spoiled Rich was wearing a stylish pair of athletic shorts that matched her aesthetic surprisingly well. If anything, the mare’s heavy blush and lust-stricken expression was far more telling than anything else. Her tail was still lifted high, and her hind-legs were trembling like a fallen leaf while she tried to stand upright. She took one look back at her shorts, and had to bite her tongue to keep from snapping at the Princess.

“You don’t have to thank me,” assured Twilight with a smug, shit-eating grin. “I certainly can’t have you walking around outside with the belt or training pants showing, can I? You might be getting punished, but I still want to give you some dignity~”

Spoiled tried to turn herself around, which was easier than expected considering she was wearing three different layers over her rump. If looks could kill, her furious glare on Twilight would’ve given Spoiled Rich a high-class trial for murder by decapitation. Unfortunately, her buckling legs and twitching tail prompted her to merely growl through her clenched teeth. “Y…Y-You won’t get a-away with this…”

“We’ll see about that,” stated Twilight in a matter-of-fact tone. She used a flash of her magic to teleport the folder full of evidence in her aura, hovering right over Spoiled’s head as a visible threat. “Now, unless you want me to prosecute you the normal way, I would suggest you spend this week thinking over your actions. Maybe then, I’ll decide whether or not you can take off that belt.”

Spoiled Rich’s glare faltered with a couple of twitches, before she hung her head and whimpered pathetically. She couldn’t even say a word, mostly because she was afraid of opening her muzzle and blurting out another heated moan. That belt was still striking her marehood relentlessly, causing her whole body to tingle and her fur to stand on end. She wasn’t sure how she could be able to handle such a fate for an entire week, but she could only hope this was better than being thrown in a jail cell.

“Nnnnnghhh…” Spoiled didn’t say anything, nor did she even give Twilight a courteous wave goodbye. The mare merely wobbled her way down the hall, breathing out in shaky moans as she tried to make her way to the front door. Twilight didn’t say anything, and just let the mare go with a cocky grin on her face. The only thing she did to assist Spoiled was using her magic to undo the metal chains on the door so she could walk freely.

Spoiled tried to run out of the castle, but it looked more like she was hobbling over hot coals. The more she tried to move her legs, the more she could feel her buzzing belt rubbing up against her clit and getting her wetter by the second. She was grateful it was still dark outside, since she wanted to get back to her mansion before the sun rose so she could try to situate herself. But as her teeth clenched tightly, Spoiled could only imagine how long she could stand being edged without mercy.

Twilight chuckled as she watched the mare from the open doorway, now holding a freshly brewed cup of coffee in her magic. She took a sip in satisfaction, just as Spike came waddling down the stairs tiredly.

“Ughhh… wh… what are you doing up so early?” Spike rubbed his half-lidded eyes with a clenched claw.

“Oh, nothing. I just wanted to get a good start to the day.” Twilight already had a full pot of coffee ready for the dragon, which she floated to him to make his face light up. “Here you go! Just the way you like it.”

Chapter Two

A Couple Hours Later

“AaaaaAAAAHHH!!!~”

Spoiled Rich felt absolutely horrible. Titillated and pent-up beyond comprehension, but still horrible nonetheless.

She tried her best to remain “normal” when she returned to the house and pretended to wake up. Although as soon as she slipped into bed, it didn’t take long for her fidgeting legs to stir her husband awake. Spoiled had to bite into her pillow in an attempt to muffle her moans, but she still caught Filthy Rich’s attention when he saw her humping into the mattress. He tried to lean in with a couple perks of his brows, but a firm smack of her hoof kept him to his side of the bed. While Spoiled squirmed uncomfortably against her bedding, Filthy just grumbled facing away from her.

She eventually waddled off into the bathroom, wincing when she heard the belt’s buzzing (not to mention the soft crinkling of her training pants) from her backside. Spoiled had no idea whether or not her spouse could hear it, but it felt almost deafening to her own ears while the bedroom was so quiet. It was fortunate that she and Filthy Rich had separate bathrooms, since she spent nearly an hour inside her own trying to get herself off. She tried everything from a hot shower, a cold shower, grinding against the bathtub, and even trying to shove a q-tip through the keyhole. But alas, all that the mare did was leave herself thoroughly exhausted while her pussy was given constant stimulation.

Nothing could’ve been done to undo the belt’s lock, or even loosen it from her waist. And despite how furiously she tried to rub herself through the belt, that incessant buzzing wasn’t intense enough to set her over the edge. It was almost as if the magic within that belt was synced up with her arousal, knowing exactly how much pleasure to deliver to her overwhelmed nethers without actually bringing her to climax. The constant edging was becoming quite maddening, even an hour after being forced to wear it by that sadistic Alicorn. By the time she finally left her bathroom, still wearing the shorts and training pants underneath, it didn’t seem like her husband was suspicious in the slightest; although, Spoiled was aware that she usually spent that long in the bathroom most mornings anyway.

Spoiled only spent about ten minutes with her family in the kitchen eating breakfast, which was thankfully prepared by their personal butler and not herself. She tried to sit upright in her chair with her legs tightly pressed together, but she had to keep her hips from thrusting while her breathing was so faint and rapid. She wasn’t sure how in Equestria she was able to maintain her composure, since her hooves were constantly crossed and fidgeting underneath the table while she chewed her toast. Luckily for the mare’s sake, being seated right beside her daughter was just enough to keep herself in control for that brief moment. Although, given how badly she was squirming in her chair, she was sure that the filly overheard some of the muffled crinkles of that plastic between her belt and spandex shorts.

Diamond Tiara and her Dad remained strangely silent, mostly because both of them were able to see the flustered blush that was radiating from Spoiled Rich’s cheeks. The two shared a puzzled look, but neither of them bothered to ask what was wrong. If anything, they were probably assuming she was in one of her “moods” that could ruin a pleasant day in an instant. Luckily for Spoiled’s sake, her frazzled expression and uncomfortable squirming proved to be a good distraction for the covering she was wearing.

Eventually, Diamond had to bite the bullet as she tried to get her attention. “Uhhh… Mom?” she asked somewhat cautiously. “Is… everything alrigh--”

“Y-Yes! Yes!” Spoiled frantically nodded her head as she straightened up in her seat, like she was a student almost caught sleeping in class. Her lips tightened up with a light groan, while her crossed legs tensed up briefly under the table. Her muzzle twitched into a tight wince when she saw both Diamond and Filthy staring at her so peculiarly. That constant buzzing from her belt was ringing in her head without pause, keeping her from thinking too coherently. She could only hope that neither of them could hear those pulsations against her clit while she tried to blurt out a response. “S-Sorry, sweetie. I… I-I think I just… c-couldnt get off--OUT! O-Out of bed right…”

She closed her eyes and cringed internally. While she couldn’t tell them the truth, she couldn’t ignore how lousy that excuse sounded. Filthy Rich narrowed his eyes on her in suspicion. “Uhhh… Are ya sure you’re okay, hun? Maybe you should stay home an--”

“NO!!!” Spoiled Rich wasn’t thinking coherently when she jumped out of her seat, leaving her breakfast mostly untouched. If she wasn’t being edged over an hour straight, she likely would’ve realized how smart it’d be to stay home and avoid as many ponies as she could for the week. However, Spoiled was already being thrown into an absolute whirlwind of tantalizing torment, and the idea of being locked alone in her mansion would only intensify that feeling she couldn’t sate by her own hooves. She needed to get out of the house, just so she could do anything possible to get her mind off that belt buzzing her clit. Her legs tried to lock up with every frantic step she made out of the kitchen. “Uhhh!! I-I have a lot of errands to run! I need to flick my bea--B-BUY SOME BEANS! C-Coffee beans! And, and, and other things I need to doIjustgottagetoutofthehouseIgottagoGOODBYE!!!”

Spoiled barely had any time to grab her purse before rushing out of the house in a frenzy. Filthy Rich, Diamond Tiara, and their butler stood frozen in the kitchen with confounded looks on their faces. None of them said anything for a moment, and tried to process what the heck was wrong with that mare. Eventually, Filthy Rich just shrugged his shoulders and went back to his plate. “Well… alright then.”

Diamond shrugged as well, not minding being away from her Mom sooner than usual. Even the butler let out a silent sigh of relief as he took her plate from the table. It was probably a good thing that Spoiled Rich left so quickly, otherwise she would’ve been upset to learn how easily they accepted her hasty departure.

“Nnnnnnffffff…” Spoiled Rich was speed-walking down the lengthy driveway from her mansion, shivering each time she felt a distinct squishing between her clenching legs. Her shorts appeared to still be dry, much to the mare’s relief; but underneath that tight spandex, Spoiled could feel the distinct dampness of that padding pressed up against her locked crotch. She had no idea how much she was leaking in forced arousal, but it already felt like she pissed herself while her pussy was continuously winking and convulsing. The warm, soggy padding was bunched right up against her without any give, which made every sharp pulsation and throb of the belt that much harder to ignore. If this wasn’t some twisted punishment with no climax, Spoiled wouldn’t have minded such a taboo sensation that badly; but in her current state, all that the training pants were doing was leaving her feeling worse.

“Aaahhh!~” Spoiled Rich barely made it past her mailbox before she stopped dead in her tracks. A couple of harsh pulsations from her belt delivered an intense stimulation right to her poor clit, which nearly knocked her to the ground. There may not have been that many other houses in that upper-class neighborhood, but Spoiled still tried to lean against her mailbox and bite her hoof to keep from shrieking. While one of her forelegs was wrapped around the mailbox, her other hoof went down to dig against that soggy padding against her crotch. The harsh rubbing wasn’t even close to effectively getting her off, but the additional pressure (as well as the warmth of her arousal soaked into her training pants) provided the briefest amount of pleasure to counteract those harsher pulsations hitting her without mercy. Her head lurched down while her eyes were shut, and she panted heavily while rubbing herself in an attempt to get the slightest semblance of control. “Mmmmmffffff…”

Spoiled Rich soon became lost in her unending arousal, hugging the mailbox and trying her best to rub her personal box. But even while pressing her hoof up against that pesky lock, the vibrations hitting her marehood weren’t intensified enough to sate her. She wasn’t sure how long she spent outside her home rubbing her crotch like an absolute pervert, but she wasn’t able to think coherently while shuddering between brief groans. Her eyes eventually reopened with a flutter, her face deeply blushed and her muzzle agape. “AaaaAAAAHHHH!!!”

Spoiled’s lustful moan instantly morphed into a packicked shriek the moment she realized she was no longer alone. She was still hunched over her mailbox, her hoof now stuffed into her shorts to confirm the shocking sight her mailmare was witnessing. Derpy Hooves was standing in stunned silence, her off-center eyes wide-open and a couple envelopes clutched in her shaky hoof. Spoiled Rich was frozen in place like a kid with their hoof in the cookie jar, her hips still writhing from that belt vibrating beneath her padding. Derpy didn’t say a word, which meant that Spoiled’s feeble response could be heard clear as day. “... uhhhhhhh…”

Her blue eyes darted between the shocked look on Derpy’s face, and down at the mailbox she was hugging for support. With her blush deepening, Spoiled Rich opened the front of the mailbox. Derpy slowly leaned in, avoiding eye-contact with the mare as she stuffed the envelopes inside. Then without saying a word, the mailmare quickly flew off to get away from the embarrassing situation. Spoiled remained in place for another minute or so, before she sheepishly pulled her hoof out of her shorts.

“D-Dammit…” Spoiled shuddered in a mixture of shame and forced titillation, and hobbled away from the mailbox to walk her way into town. She hadn’t even left her own neighborhood, but she knew that this was going to be a long day…

On a normal day, Spoiled Rich’s trek from her mansion to Ponyville’s town square would usually take less than five minutes. But on that particular morning, the mare’s current predicament caused her trip to take more than fifteen. Her slow trot down the main road, accompanied by her shaky steps and widening gait, were more than enough to catch the attention of ponies passing her by. She tried her hardest to keep a cordial smile to appear normal, but her heavy blush and twitching muzzle made it painfully obvious something was off. Not to mention, most of Ponyville’s citizens weren’t used to seeing her smile, unless it was after she made some poor retail employee cry.

Spoiled Rich could only hope that her shorts weren’t too obvious to her affliction, even though the padding underneath that spandex remained rather slender and form-fitting. It helped that she was still wearing her blouse and jewelry, so the garment covering her backside didn’t stand out too badly. If anything, her strained and blushing face was a much bigger tell than her outfit that something was amiss. Unfortunately for Spoiled, she became more paranoid through her forced pleasure when ponies tried to avert their eyes or keep their distance from her.

“Mmmnnnghhh…” The mare gritted her teeth, and shuddered when she felt more of her arousal trickling through her belt to soak her padding. She was afraid to look down and inspect her shorts, not wanting to see a puffed-out bulge to emphasize she needed protection. The warm, soggy padding continued to press in tightly against her marehood, which in turn altered the vibrations from the belt just enough to keep her from cumming in her shorts. The edging was growing more relentless by the time she entered town, much to her growing dismay.

Spoiled Rich shakily pulled out a small notebook from her blouse, which she had actually written up the night before, Her muzzle wrinkled tightly as she scanned the list of errands she had to do today, silently cursing herself for the first item which was already crossed off: Visit Twilight Sparkle’s Castle. Below that were several more things that had to be done that day:

-Buy groceries from the market

-Purchase two bottles of wine for Filthy Rich

-Pick up the dress from Rarity’s store

-Get constipation medication from Pharmacy

“Ugh!” That last entry really got to her, mostly because of the padding she could feel against her rump. If it wasn’t for that stupid belt, the constipation meds would’ve been the most embarrassing part of her day. However, due to how badly she was writhing in her tingling attire, it was hard to think about that concerning pressure building up in her gut; while it was manageable earlier that morning, she could only hope it wouldn’t add anything to her already taxing day. Or at least, perhaps it could be ignored for the time being.

She closed her eyes with a sharp sigh, and paused long enough to plan out her options accordingly. She cursed herself for not bringing her saddlebags with her, which meant she would have to get a bag for her items as well. She knew that Rarity had complimentary tote-bags for the dresses, so there’s a chance she could get a spare for groceries and other things. So with a bitten lip, and a harsh shiver that made a pony do a double-check while walking past her, the blushing mare made a beeline for Carousel Boutique.

“Mnnnghhh… Please be open, please be open, please be open…” She whimpered to herself out-loud, which was the only way she could think to walk briskly without focusing too much on her winking cunny. The tingling pulsations to her pussy were droning on mercilessly, which made those titillating waves feel more painful than pleasurable. She wasn’t sure how much more she could take, but she hoped that she wouldn’t leak through her shorts from how badly she was convulsing inside of her training pants.

Spoiled ended up bumping into several different ponies on her way to Carousel Boutique, although she tried to scurry past them with a quick “Sorry” without moaning. She was sure she still did, since every other exhale came out as a pent-up groan. Her tail was raised up high, which caused a couple of those ponies to turn around and see the tight shorts emphasizing her backside. While the belt and training pants couldn’t be seen, Spoiled still felt horribly exposed by the time she wobbled to the shop’s front entrance.

‘TAP! TAP! TAP! TAP! TAP! TAP! TAP!’

With how frantically Spoiled knocked on the doors of Rarity’s shop, anypony who walked past merely assumed she had to go to the bathroom. It didn’t help that her legs were bunched in tightly together, which made the pressure more intense as her hips writhed from the belt’s harsh vibrations. Her head reeled back with her eyes clenched, and she took several deep breaths to try and keep herself in control. But alas, by the time the doors finally opened, the first thing to come out of Spoiled’s muzzle was a slutty moan. “AaaAAAHHH!!~ Nnnffff…”

She winced and kept her eyes shut, not wanting to see the puzzled expression on Rarity’s face. It was still early in the morning, so the prim unicorn was wearing a stylish red kimono while holding an espresso cup in her aura. Rarity narrowed her eyes on Spoiled Rich in confusion, but she tried not to say anything about the mare’s clearly overwhelmed blush. Instead, she cleared her throat before speaking cordially. “Err… Why hello there, Mrs. Rich. Is… Everything alright?”

“Y-Yeah! Yeah…” Spoiled nodded frantically alongside that lie, but needed to let out another shivering breath before she could look Rarity in the eyes. She was still squirming with her bottom lip tightly shut, and she breathed in before blurting out, “S-Sorry for coming by so early! I just… I-I was hoping to check up on my dress?”

“Hmm? Oh, of course! Please come in.” Rarity didn’t seem to mind her early arrival, and stepped aside to invite Spoiled into the shop. “I actually finished most of the final touches last night, although I was hoping to ask about some possible alterations. If you’re willing to wait in my main room, I’ll freshen up and be with you shortly.”

Spoiled nodded with an embarrassed look, and waddled over to the main showroom of the shop without saying a word. The mare quickly sat down on one of the fashionista’s fainting couches, but she took her time settling in as she grinded her ass against the plush cushioning. Rarity had already disappeared into the kitchen, which allowed Spoiled to let out a slightly relieved sigh. But while she closed her eyes to compose herself, Spoiled didn’t realize that both of her front hooves were nestled between her legs, right up against her crotch. And after a couple heavy exhales, she seemed to be too distracted to feel her hips grinding up against her forelegs softly. “Nnnnnnnn…”

Before she could try and stop herself, Spoiled Rich was moaning under her breath while humping her hooves on Rarity’s couch. She was lucky to have padding between her marehood and the shorts, otherwise she likely would’ve left a stain of her arousal on that expensive piece of furniture. Her hips started to thrust more strongly, eliciting muffled squishes and crinkling each time it pressed up against her hooves. Her belt kept her from reaching a proper climax, but the natural feeling of lust was too strong for Spoiled to stop herself. Her mind was growing more clouded the longer her pussy was being stimulated, which made her grind harder against her forelegs without even realizing it. “Aaahh! Mmmphhh~ Aaaaaahhhhh…”

“Oh, do you need anything, Mrs. Rich?”

“NNNGHHH!!” The sound of Rarity’s voice in the other room managed to jolt Spoiled out of her temporary state of inhibition. She tensed up hard on the couch, and nearly pissed herself in fear. She tightly crossed her hind-legs and pulled her hooves away from her crotch, but that strong surge of pressure still struck her crotch badly enough to make her shudder in her seat.

Since that belt was buzzing so incessantly against her nethers, it was hard for her to guess how much of that pressure was from her punishment, or from her own swelling bladder. Unfortunately, the urge to piss was the last thing on the mare’s mind, and she was too pent up to even realize it.

Luckily for Spoiled, the sound of Rarity’s hoofsteps was loud enough to make her sit upright and force a “natural” pose on the couch. In reality, the mare looked unbelievably stiff and blushy in her awkward pose, like a teenager trying to avoid distraction from what was hidden in their backpack. Rarity paused and had to do a double-check when she returned to the showroom, her eyes narrowed in suspicion. However, the unicorn merely sighed with a shrug before walking up to her. “Well, thank you for showing up so… enthusiastically? To be honest, I’m quite grateful you arrived earlier than scheduled.”

“O-Oh, ummm… i-is that so?” Spoiled Rich tried to give her a gracious smile, but her lips were far too tense to keep it from looking off-putting. Her legs continued to tense up with her muscles spasming, despite how badly she tried to keep herself still in front of the dressmaker. She could feel hot her cheeks were getting, but it was nothing compared to her marehood that continuously winked and leaked into her padding. Nevertheless, she hoped that the skew in Rarity’s muzzle was more from puzzlement than disgust.

“Err, well I… I was wanting to double-check your measurements to ensure the dress was a proper fit.”

Spoiled froze in place, her locked smile just barely serving as a mask for the horror she felt in that moment. Rarity lit up her horn to float out a long measuring tape from her workspace. “Now before you say anything, I’m aware that you sent me your measurements before I made the dress. But considering it’s for a charity formal, I wanted to verify things in case I needed to make any alterations. Is… that alright with you?”

Spoiled wanted nothing more than to say no to the mare’s face, and storm out with her dress in tow. Given how badly she was handling that belt buzzing at her pussy, she couldn’t imagine standing still long enough for Rarity to measure her correctly. Not to mention, she really didn’t want to risk the unicorn getting in too close and smelling the arousal wafting from her shorts. But alas, even in her predicament, Spoiled knew that she needed to try and get an extra bag for her errands. So despite her extreme apprehensions, she closed her eyes with a pained wince and shrugged begrudgingly. “W-Well, ummm… I-I suppose that could be a-aranged…”

She reluctantly stood up from the couch, shivering with a flustered groan when she got back on her hooves. Her nethers were flaring up from the new position, now feeling the belt’s relentless vibrations without any added pressure from her forelegs. All she could do was close her eyes, and try her hardest to stay still for that measuring tape. Spoiled could only hope that Rarity was professional enough to keep her composure, or at least to not say anything if things go awry…

“This will only take a moment…” Rarity went around to Spoiled’s backside, most likely to avoid looking the mare in the eye. Out of Spoiled Rich’s line of sight, Rarity allowed a more confused-looking wince to be seen on her face. She wasn’t sure what was up with her, but she wasn’t one to ask any prying questions if it meant getting her out of her already taxing schedule. So instead of trying to figure out why Spoiled was acting so weird, Rarity quickly began to get her measurements; her horn was lit to hold both the measuring tape, as well as a clipboard in her aura. “Alright, let’s see…”

Spoiled Rich had her eyes tightly shut, her muzzle clenched like she just sucked on a lemon. She could hear the buzzing from that belt quite audibly in her head, but she had no idea if her shorts were thick enough to conceal it from Rarity’s keen hearing. Her thighs kept twitching from the convulsions of her wettening marehood, but her knees locked up steadily enough to remain in place. She sucked in a deep breath when she felt the tape wrap around her waist, just above the hem of her shorts and training pants. That additional touch made it feel like a pair of lips were sucking her clit right then and there, which caused a light whimper to escape her muzzle. “Mnnnghhh~”

Rarity paused cautiously. “Is something wrong, dear?”

“N-NO! No, uhhh… p-please keep going…” Spoiled cringed when she heard how frantically her voice sounded. It may have been from the desperation of getting this over with, but it also sounded very obviously horny. Rarity didn’t say anything, but she replied with an awkward nod before moving the tape elsewhere. Another sharp gasp came out of Spoiled’s muzzle when she felt the tape wrap around one of her fidgeting thighs. She could feel her pussy leaking more into the training pants, which were getting increasingly heavier within the confines of her shorts. Her marehood was convulsing hard inside of that vibrating belt, stimulating her like mad and causing her to bite her hoof. “Nnnnffff… Hnnnnghhh~”

“Mrs. Rich, are you sure everything is alright?” Rarity’s voice was bordering between worry and annoyance when she paused once more. “I only have a couple more measurements I need to double-check.”

“I-I’m okay, I swear!” she blurted out with her head hung low. “S-Sorry, just… just a little too much coffee…”

That lie may have been faker than her charity donations, but the mention of fluids caused her to freeze up with her eyes wide-open. She had been under so much strenuous teasing, that it wasn’t until then that she finally realized how long it had been since she peed. Her muscles continued to twitch and spasm in place, but the terror Spoiled Rich felt helped her immensely in that moment. Sure, she was still feeling those sharp pulsations hitting her clit like crazy, but she was also able to notice that growing pressure from her bladder. Even though she was adequately prepared for any accidents, her pupils shrank in dread nonetheless.

“Hmmm…” Rarity was becoming more uncomfortable, but she took advantage of Spoiled’s stoic state to get the last of her measurements confirmed rather quickly. Much to her relief, it seemed that all of the numbers sent by Spoiled weeks ago were still accurate to her form now. She needed less than a minute to complete Spoiled’s measurements, and smiled softly in satisfaction. “Alright, I think everything is in order, Mrs. Rich.”

Her magic then grabbed hold of the back of Spoiled’s waistband. “Although I might need to double-check your waist…”

Rarity’s eyes shot wide-open, while Spoiled gasped silently in shock. She hadn’t expected the unicorn to pull back her spandex shorts, which in turn exposed her training pants just underneath. The unicorn blushed profusely, and snapped the waistband back in place less than a second after seeing the padding on Spoiled’s rump. That elastic slap was more than enough to make the older mare moan out deeply. She crumpled on the floor in a moment of weakness, her knees quivering and her pussy getting wetter behind her belt.

“O-OH! Ummm… N-Nevermind! I have your measurements!” Rarity quickly scurried out of the room, her face a beet-red to hide her shocked expression. Spoiled was trying not to panic while hiding her face, unable to even look over at the pony who saw her padding. She hoped that the mare wouldn’t say anything about this, but her winking marehood and swelling bladder were keeping her from dwelling on those thoughts for too long. From the other room, Rarity blurted out, “D-Don’t worry, Mrs. Rich! I have your dress right here! Uhhh… I-Is there anything you need? I promise I won’t say a word!”

Spoiled may have been overwhelmed while hunched over on the floor, but she threw her head back up to try and regain her focus. Since Rarity sounded a bit panicked, she could only assume that the unicorn was trying not to get in any trouble for seeing her training pants nonconsensually. After a harsh shudder, the mare struggled to get back up right and speak somewhat confidently. “Nnnfff~ I-I, errrr… I might need a… a second bag, please?”

It was impressive she was able to remember that detail, as well as the fact that she actually asked politely. Although, given how badly her mind was being frayed by the torture to her clit, it was obvious she wasn’t entirely herself. Spoiled was halfway to the front doors when Rarity ran up behind her, and floated the two bags atop her back. “Umm, please have a nice day!” said the dress-maker with a flustered smile, her eyes repeatedly darting down at that more noticeable padding beneath Spoiled’s shorts. “Your diap--DRESS! Your d-dress and second bag are right here! Your husband already prepaid, so uhhh… have a nice day.”

“BYE!” Spoiled barely noticed the bags on her back when she waddled away from the shop as fast as she could. Rarity remained at the doorway with a confounded look, and stared at the mare’s rump as she rushed off. A couple of ponies passing by paused to see what was up with Spoiled Rich, but Rarity was the only one who noticed that faint bulge in her shorts…

In addition, she also saw something else that made her ask herself, “Was… Was she… leaking?”

Chapter Three

The spandex shorts may have been a rich shade of black, but they weren’t completely void of hiding Spoiled Rich’s predicament. The mare’s odd behavior certainly helped to detract focus from her backside, although that also meant that she could see the odd stares ponies were giving her directly. Unfortunately, while she walked down Ponyville’s main street with her bags in tow, her shorts seemed to be getting thicker the more her training pants soaked up all of her arousal. And to make matters worse, the bottom hems of her shorts were getting a little damp along her inner thighs.

Spoiled had to keep her head lowered in shame while waddling down the road, even though she could feel various ponies’ stares among the sea of awkward silence. The Ponyville Pharmacy was the closest place in her list of errands, so she went right towards it without stopping. By the time she walked through the glass doors and entered the modest shop, she could no longer hear the crinkling of her padding between her legs over the sounds of the belt’s buzzing; instead, she could sense the distinct wet squishing of her thighs pressing up against her soaked training pants. She wasn’t sure how badly she was leaking in forced arousal, but her poor marehood couldn’t stop winking and sending merciless shivers up her spine. Because of that, she was starting to feel like a warm dish-sponge was bunched up against her pussy.

“Mmmfffff~” The mare stumbled down the aisles with a heavy blush, and tried not to glance over at the pharmacist nearby. She went right towards the dietary aid section, where various fiber supplements and constipation remedies were available. Spoiled wasn’t paying much attention, and just grabbed the first thing she saw so she could get her second errand over with. All she noticed was a bright purple bottle, and not the labels marking it was “Extra Strength” and “Instantly Effective”. Although to the mare’s credit, that concentrated laxative would certainly aid with her constipation.

Speaking of bottles, Spoiled Rich was lucky enough to see a display of wine bottles by the register. They were insultingly cheap compared to the usual brands she and her husband bought, but by that point she wasn’t feeling too picky. She took two of the pricier bottles from the stack of boxes, which were less than forty bits total combined with the laxatives. While she was at the register, Spoiled was constantly shuffling between her hind-legs while darting her eyes anxiously. The cashier didn’t say anything about it, but it was clear that she took notice of the mare’s behavior. Since Spoiled was the only one to hear the buzzing beneath her shorts, the cashier could only assume that she needed to go to the bathroom; of course, considering how badly her bladder was starting to strain, that assumption wasn’t exactly inaccurate.

After completing two of her errands at once, there was only one last task Spoiled had to complete for the day: Buying Groceries. Sure, the mare should’ve been grateful she was completing a day’s worth of tasks in the span of a single morning; on any other day, she would’ve used that spare time to indulge herself at the spa or “double-check” her daughter’s test scores at the school. But with what she was currently wearing, Spoiled would’ve preferred not to have that much free time after her shopping was finished. Her marehood was being stimulated so hard, the only reason she hadn’t completely broken down yet was because she was trying to focus on other tasks. Unless she could find an effective means to ignore the torment on her aching clit, Spoiled could only dwell on how badly this afternoon was going to get for her.

“Aaahhh!!~” While both of Spoiled Rich’s tote bags hung against her sides, she ended up stumbling into an alleyway when her arousal wouldn’t let up. She was only a block away from the Ponyville Marketplace, but she had to do something to quell that heat ruminating in her nethers. Spoiled rushed behind a filthy dumpster, and leaned up against the wall so she could press her hoof up against her padded crotch. The rancid stench of the dumpster was more than a little distracting, although it didn’t keep her pussy from convulsing behind her belt. Regardless, the mare was too riled-up to even care while rubbing herself in such a depraved manner. “Mmmnnnghhhhh~”

Her hips were humping against her hoof, while the squishiness of her training pants became more audible with each crinkly rub. The warm arousal soaked into her padding was matting the fur around her crotch, but she didn’t seem to notice it was also dampening her legs past the hem of her shorts. The black spandex was growing darker between her legs, rendering her training pants completely useless after being used so thoroughly throughout the morning. If anypony were to see her from behind, they likely would’ve thought she pissed herself if they got in close enough. Although in that alleyway, they’d probably be more distracted by the posh mare trying to masturbate behind a dumpster.

“Nnnnffff!! C-Come on…” Spoiled Rich gritted her teeth, and tried to keep her voice fairly muted while grinding against her belt. She could feel those sharp pulsations hitting her marehood at a steady pace, keeping her lips winking and her clit throbbing just barely out of reach. The edging she was going through was intense enough to basically feel painful by that point, not that it kept her from trying to sate herself. She desperately grinded her crotch with a heavy groan, and leaned against the wall so she wouldn’t stumble to the ground. As her knees wobbled beneath her weight, and her head hung down to hide her blushed look of shame, the mare didn’t seem to notice when small rivulets of her trickling arousal were dribbling down the inside of her legs.

“Aaaahhhh!!~” Spoiled couldn’t keep her lustful moans to herself, and could only hope nopony got too close to the alley’s entrance to overhear them. Her voice echoed out between the brick walls, along with the distinct squishes of her crinkly padding. The glass bottles in Spoiled’s tote bag clinked around inside, which only made her debauchery even louder and harder to contain. But alas, despite how brutally her hoof tried to press in against her crotch, all she could feel was that smooth metal buckle that kept her from touching her aching pussy.

Well, that and the painfully intensifying pressure of her bladder.

“Aaahhh!!” Spoiled Rich’s eyes rolled back, and her head reeled up as she tried her hardest to focus on the pleasure her clit was going through. Since she was “alone,” the best she could do was at least think of something hot enough to set her off. She had no idea if it was even possible to counteract Twilight’s sadistic magic, but at that point it was all she could hope for. Spoiled clenched her eyes and tried to think of any lewd, kinky ideas that might tip her over the precipice.

‘Hot, throbbing cocks… getting a facial from that stallion up the street… taking it up the ass in ways Filthy never could manage… mnnnnghhh, come on!’

Spoiled was panting heavily, but ended up whimpering when she felt the belt’s pulsating waves lessening in intensity the longer she thought of dirty images. She was close to sobbing by the time she stopped rubbing her belt so hard, realizing too late that she wasn’t going to reach climax that easily. She wanted to just pull her hoof away completely, but the vibrations went right back to their regular intensity before she could do so. It was obvious that she was stuck enduring the magic, which kept her hips thrusting and her training pants thoroughly soaked. Spoiled eventually lowered her head again, but kept rubbing her crotch blankly like an impulsive action. In that state of defeat and frustration, all she could do was try to ignore the muffled squishes and clinking bottles that echoed in the alle--

“HEY!!!”

“AAAHHHH!!” Spoiled fell to the ground in a panic, not expecting to hear a stallion’s voice right behind her. She stumbled face-first in the alley, pointing her soggy rump right at Mister Cake who was at the back entrance of his shop. Spoiled was frozen in a panic, unable to think of any excuse for why she was unsuccessfully masturbating behind Sugar Cube Corner. She couldn’t even look back at the stallion in shame; although, considering how deeply the yellow stallion was blushing, it was probably for the best she couldn’t see his baffled expression.

Mister Cake was still holding the garbage bag in his hoof, but his bulging eyes were glued to the view of Spoiled Rich’s swollen and damp backside. By that point, the back of her spandex shorts were obviously wet from the training pants soaking completely through. And since the stallion was a father, he was able to see the bulge of her padding without much question what it was.

“... uhhhh…” Mister Cake’s muzzle was slightly agape, but his voice was audible enough to make Spoiled Rich wince in horror. Her ass was still sticking up, so it trembled a bit when she shuddered under her breath. She shakily tried to pull herself up in an attempt to make her escape, but the damage had already been done. She didn’t even turn her head, and just clumsily took her bags before stumbling her way out of the alley. All the while, Mister Cake just stared at her without a word from his mouth, or even a blink from his eyes. It wasn’t until she disappeared from sight and returned to the streets, that the stallion was able to say something to nopony in particular. “... Jeeze, she could’ve at least gone to a bathroom or something for that…”

He shrugged with a slightly disgusted look on his face, and tossed the trash into the dumpster before returning to work.

The poor mare was looking absolutely disheveled, with heavy bags under her eyes and her mane notably unkempt. She was still twitching from the belt’s relentless teasing, which made her overall appearance resemble a junkie more than the posh socialite she tried to be. The training pants had gotten so bloated from her leaking arousal, that the thick bulge of the padding stuck out against her spandex shorts. And speaking of leakage, the crotch and back of her shorts were noticeably darker than the rest of the garment, matching the matted fur along the inside of her thighs.

Spoiled Rich tried to keep her composure with a forced smile, even as she walked awkwardly through the marketplace. Many of the ponies and vendors were staring at her without much subtlety, although most of them kept to themselves and refrained from bothering her. It was clear that something was off with the mare, but it wasn’t like her reputation gave her many allies in that situation. In fact, she could’ve sworn she heard a few guilty snickers from behind, even though she wasn’t aware of how badly she was soaking through her shorts.

“Nnnnghh… F… F-Five onions, please…” Spoiled struggled to get all her shopping done without much issue, which resulted in many of the vendors experiencing the mare acting strangely nicer than usual. Instead of her usual passive-aggressive remarks or unnecessary haggling, she paid full price and remained cordial while purchasing her produce. A few of the ponies glanced at one another in befuddlement, unsure whether to feel relieved or concerned about Spoiled’s behavior. Of course, due to the obvious dampness between her legs, nopony felt brave enough to point it out and ask if she was okay.

“T-Thank you…” Spoiled Rich tried to quietly make her purchases through her twitching state, thankfully not receiving much back-talk from any of the ponies selling produce. Even though her face was blushing a deeper shade of red than the tomatoes she stuffed into her bag, she maintained her resolve just enough to keep from moaning out loud. Her tail was still lifted up and spasming behind her, basically beckoning anypony’s eyes towards the sorry state her borrowed shorts were going through. Her breaths were faint and rapid, even when she tried to grit her teeth and complete her shopping list. “Uhhhh… I-I’d like to ge--NNNGHHH!!!”

The mare jolted up with a frozen look of terror on her face. It wasn’t the belt’s constant titillation that struck Spoiled Rich in that moment, which caused about half a dozen ponies to glance over at her puzzledly. Her legs clenched up and tried to cross together, all while her tail flagged up even higher in anticipation. Despite how much her rampant arousal was overtaking any other impulses, Spoiled wasn’t able to ignore a certain biological impulse any longer. Her poor bladder, which had slowly been building up since the previous night, appeared to have reached its absolute limit. The warning signs struck her like a brick to the face, even though she should’ve realized she was hitting her peak hours ago. Her blush quickly dissipated to reveal a paled, horror-stricken face with her pupils shrinking immensely. She only froze for a couple seconds, but it felt like hours when she realized the floodgates were just about to burst.

And to make matters even worse, she knew there was no way to run towards a bathroom soon enough.

“... oh no… oh no, oh no, oh no, oh no…” Her breathing became more forced and rapid, almost sounding like she was about to go under labor. Her head lurched down, but it did nothing to hide the fear that was plastered across her face. She could only take a couple steps forward before clinging to the side of a vendor cart, and she cried out briefly from the intense pain. Unfortunately, that was when the belt vibrated especially hard against her aching pussy, turning her yelp into a hearty moan halfway through. “Aaahhh!! Mmmnnnnnnnffffffff~”

Her eyes were so tightly shut, and her muzzle was clenched with such intensity, that she didn’t notice somepony walking up behind her. She was clutching that vending cart for dear life, while her knees tried to bend inward and keep the inevitable from happening. Unfortunately, even with the protection she was wearing, it was all for naught when she felt a hoof rest against her back.

“Ummm, Mrs. Rich?” asked Roseluck, as she and about a dozen other ponies had paused their shopping to see what was up with the disheveled mare. “Are you oka--”

“GNNNAAAAHHHHH!!!~”

Spoiled Rich couldn’t take it anymore, and her body finally gave out in public. Her knees bent down to get in a squatted stance, while her tail remained lifted to keep her shorts fully exposed. Due to how soaked her training pants already were, there was nothing to stop that monsoon that erupted out from between her legs. As the mare cried out in a mixture of agony and forced lust, she could hear a symphony of gasps and yelps from behind her when her bladder let loose. A gushing torrent of hot urine erupted out, quickly seeping through her padding and practically squirting from her spandex shorts. Her head hung even lower, while her voice lumbered out in a deeply mortified moan.

“AaaaaAAAAAaaaahhhh…”

Spoiled Rich spent nearly a whole minute pissing herself, completely soaking her hind-legs and leaving a puddle between her quivering hooves. Her muzzle hung agape while crying out feebly, hoping to any higher powers listening that she could leave that marketplace with the slightest semblance of dignity. But alas, while she unloaded in her shorts like a toddler, the vendors and townsponies could only gawk with mixed looks of shock and pity. A mare covered her child’s eyes and diverted them away from the spectacle, which left others slack-jawed and blushing in stunned silence. By the time she finally finished her shameful expulsion, her padding had bloated out to something that more resembled a diaper bulging through her soaked shorts. Meanwhile, the rest of her body was trembling from the sheer horror of what she had just done, as well as that blasted belt that still stimulated her pussy without pause.

“NNNGHHHH!!!” Spoiled couldn’t take it anymore, and she took a deep breath before bolting off. The mare ran at top-speed through the marketplace, leaving nothing but her piss-puddle and a dozen gobsmacked ponies to reflect on what they just saw. A couple of her groceries fell out of her bag due to how frantically she tried to escape that shameful display. Unfortunately, before she could leave sight of the town’s marketplace, Spoiled Rich could’ve sworn she heard a few guilty giggles and murmurs from the ponies she refused to look at. Tears were building up at the corners of her eyes, and she ended up crying out while running. “AAAAAHHHH!!!”

Chapter Four

In less than five minutes, the older mare managed to make record-time running from the market back to Twilight Sparkle’s castle. Even though she was running like a prisoner escaping Tartarus itself, her soaked legs and sagging shorts caught many ponies’ eyes when she rushed past them. A couple tears had strayed from her welling eyes, leaving her mascara ruined with black lines trailing down her face. By the time she returned to the castle, she looked like an absolute wreck while banging on the front doors. “TWILIIIIIIGHT!!! Twilight, PLEASE OPEN UP NOW!!!”

Much to her surprise, the doors opened up rather quickly. She was met with the sight of Twilight Sparkle once more, who stood by herself with a smug grin on her face. If it was anypony else standing outside the castle, the Princess likely would’ve showed a bit more sympathy for the guest’s disarranged and piss-soaked state. But in the case of Spoiled Rich, Twilight merely narrowed her eyes on her and tilted her head cheekily. “Oh, hello there, Mrs. Rich!” Her voice was just as cheerful as it was full of pure malice. “Did you have a fun morning?~”

“PLEASE, YOUR HIGHNESS!!!” Spoiled Rich didn’t care about her ruined dignity, and instantly fell to the Alicorn’s hooves while outside the castle. It was fortunate that no ponies were nearby to see the mare groveling to Twilight’s hooves so pathetically, especially while her rump was still raised to expose her soaked shorts. Twilight could see how badly the mare’s muscles were twitching, undoubtedly from the chastity belt and its fabulous edging effects. It hadn’t even been half a day, and Spoiled was already begging for mercy like a lowly peasant. “AAAHHHH!!!~ Mnnnnghhh… p-p-pleeeeeease, Twilight! T… T-T-TAKE THIS OFF RIGHT NOW!!!”

“No.”

Spoiled looked up at the Princess’ grin in shock, her quivering muzzle doing nothing to deter Twilight’s sadistic glee. She even giggled with a hoof over mouth at the sight of Spoiled’s appalled expression. Instead of giving the struggling mare any mercy, Twilight decided to bring her torment inside the castle before any townsponies could see them together. With her horn brightly lit, Twilight dragged the groveling pony inside and locked the door behind them.

“Oh, my goodness!” Twilight had a faux-surprised smirk on her face when she took notice of Spoiled’s urine-soaked clothes. “Yeesh, you only wore training pants for a few hours, and you already soaked through them? Hmph~ Maybe I should’ve given you something thicker…”

She sat down on a nearby chair, and bent Spoiled Rich over her lap like a child about to get spanked. Twilight’s magic quickly slipped off the shorts, which were completely soaked and reeking of the mare’s acrid piss. She grimaced a little from the smell, and used a poof of her magic to teleport the shorts into the laundry room. Meanwhile, Spoiled Rich was grimacing with a twitching sneer while hunched over the Princess’ lap, her yellowed training pants still wrapped heavily around her waist.

Twilight looked over at a nearby mirror, and giggled when she saw how they looked together. Spoiled could only close her eyes with a shameful sob, and she tried once more to beg for the Princess’ relent. “P-Please, Princess Twilight… P-P-Please make it stop…”

Twilight could feel the vibrations of that belt while it was pressed up against her thighs, and could only guess how badly Spoiled was feeling it on the receiving end. She was sure if either of her mentors were to see her doing all this, they would’ve had her wearing the belt and nothing else for a whole month straight. Of course, that idea only made her shiver quite antsily while biting her lip. “Nnnnfffff… I must say, it’s a nice change of pace to see you acting so humble. Even if it did make you pee yourself like a foal~”

Spoiled Rich had no idea what was going on with this Princess, but she had to bite her tongue and keep from saying anything she would undoubtedly regret. She was trembling so hard on top of the Princess’ lap, that she didn’t feel her two tote bags being floated off her back by Twilight’s magic. The Alicorn hummed curiously and inspected the bags, but didn’t invade the mare’s privacy too inappropriately. But when she discovered the concentrated laxative bottle alongside the purchased wine, her brows raised up rather curiously. “Ooooh~ What do we have here?”

She panted with a shiver, and glanced up at the bottle now in Twilight’s hoof. Spoiled wasn’t able to get a good view of the bottle, especially when Twilight was covering most of the label from how she was holding it. The Princess snickered devilishly down at her and asked, “Were you planning anything special with this bottle this week?~”

“Ugh…” Spoiled Rich hung her head with a look of annoyed disdain. “I… I-I needed something for my… c-constipation…” She grimaced from how easily she made that confession, but it wasn’t like she had much of a reason to protect her dignity by that point. Her answer seemed to really pique Twilight’s interest, as her face lit up excitedly.

“Oh, well if that’s the case…” With her mischievous smile widening by the second, Twilight decided to uncap the bottle and smell the contents inside. After taking a couple sniffs, she reeled back with a surprised “Whoo! That’s a strong grape flavor!”

While she recapped the bottle for later use, Spoiled Rich groaned and spasmed atop the Princess’ lap. “Nnnffff… T-Twilight, PLEASE! I ca… I c-can’t take it any mo--OOHHHH!!!~”

Her head reeled back like she was being exorcized, just as the belt beneath her padding buzzed exceptionally hard. She jolted hard enough to fall off Twilight’s lap, and plopped ungraciously onto the floor. She was still shivering as her ass stuck up from the floor, her yellowed padding swaying back and forth between her legs. Since she wasn’t outdoors anymore, she was able to moan more openly without trying to cover her muzzle. She grinded her face against the floor while thrusting her hips, but it did nothing to stop her quelling pussy from winking and drooling so obscenely. “AaaaAAAAaaahhh!!~”

“Mmmmmm~” Twilight took a moment to marvel at the older mare writhing so pathetically before her on the floor. If she was more villainous, she likely would’ve considered leaning back in her seat and using Spoiled Rich’s back as her personal hoof-stool. However, her recent find prompted her to decide something more devious for the overstimulated pony. While Spoiled Rich continued to squirm and drool from both ends, Twilight took that moment to pull down the mare’s padding with her magic. The soggy mass of plastic dropped down around Spoiled’s trembling hooves, which she barely noticed. She was still moaning weakly while her rear was sticking up, her fur thoroughly matted in a mixture of her own piss and pussy juices. Of course, even more of her arousal continued to dribble out from her belt uncontrollably, with a couple droplets hitting the floor.

“Alright, just a moment~” After a quick zap of her magic to teleport the used training pants out of sight, Twilight conjured up a fresh piece of padding to replace it. Unlike the faulty garment Spoiled Rich was previously wearing, this one was a legitimate, full-fledged diaper large enough for an adult. She used her magic to quickly flip over Spoiled’s body, causing her to yelp as she was thrown onto her back. She tried to thrash and squirm against the Princess’ aura, but it was to no avail. As she kept groaning through her gritted teeth, she was completely helpless to stop Twilight from sliding the unfolded diaper underneath her body.

The Alicorn quickly slid the mare’s tail through the small hole alongside the diaper’s waistband, before folding the front of the thick padding securely over her locked crotch. Once again, that chastity belt was hidden away as Twilight studiously taped the diaper shut. Spoiled tried to wince with a humiliated groan when she looked down and saw that thick, poofy garment she was being forced to wear. But alas, she wasn’t able to process the foalish attire before her hooves curled up tightly, and she tensed up with another slutty moan. “Aaahhh!!~”

“Heh~ Seems like you enjoy it…” Twilight yanked the mare back up on her hooves, forcing her to stand upright with that thick diaper widening her gait. Spoiled Rich was still trembling with a shaky moan, and was barely able to stand while her belt kept her marehood convulsing wildly. It was doubtful that her trickling arousal would soak up the padding as soon as her training pants did, but after that humiliating experience back in town, the worry was already lingering in the back of her mind. However, judging by the sadistic grin on Twilight’s face, it seemed that she was wanting that diaper to be used in a different way.

“You know what? I think I’ll just leave you be for now~” Much to Spoiled Rich’s horror, Twilight smugly turned around and began to walk away. She was still holding that bottle in her magic, but she was more determined to make Spoiled squirm a little more. While the mare’s jaw struggled not to touch the floor, Twilight began to make her way down the hallway. “You know where the door is, so I’ll jus--”

“N-NO!!!” Spoiled lunged in in pure desperation, skidding across the floor so she could grab at the Princess’ back hooves. “PLEASE DON’T LEAVE ME LIKE THIS!”

Even in her terrified and humiliated state, her padded hips were grinding against the ground while lying belly-first on the floor. Due to the Alicorn’s immense strength, her pace was unchanged while dragging Spoiled behind her. She held onto the Princess’ ankles for dear life as she skidded across the floor. “PRINCESS, I’M BEGGING YOU!!!” Spoiled wailed out in agony. “PLEASE TAKE THIS BELT OFF OF ME!!! I’LL DO A-A-ANYTHING!!!”

“Hmph… I’m sure you would~” Twilight was fully relishing in the mare’s torment while dragging her down the hallway in that currently clean diaper. The two eventually made their way back to the Princess’ office, where she finally stopped and turned around once more. Spoiled was still lying on the floor in her padding, looking absolutely pathetic in the Alicorn’s eyes. Her body was still convulsing, but it was clear that she was getting weaker in apathy despite the belt’s strength. When she looked up at Twilight, tears were bulbing at the corners as she struggled not to cry. Her muzzle was quivering badly, and she tried to blubber out, “I-I… I’ll d-d-do anything… p-please…”

Twilight’s smug smile down at her was nothing short of vindictive. She narrowed her eyes on Spoiled’s defeated state, waiting a moment to let her humiliation really sink in. “... Weeeellllllll… I suppose you could do something for me~”

“ANYTHING!” Spoiled Rich bowed her head frantically enough to smack the floor. “PLEASE! I’ll--OoooOOOOoohhh… Mmnnnnghhh~ Oh god, MAKE IT STOP!!”

“Well, I won’t do that, but…” Twilight uncapped that bottle of laxatives again, and held it out for Spoiled Rich. “If you want the intensity of that belt to be lowered, maybe you can have some of thi--”

Spoiled Rich snatched the bottle with both hooves, and sat up to frantically chug the mixture without thinking. Twilight gasped with a hoof over her mouth, her eyes widened with genuine shock and concern. Despite the bottle’s labeled strength and warnings, it wasn’t like Spoiled was going to read it when she was so desperate to cum. While her marehood winked and quivered in endless lust, she held the bottle high over her head and downed the entirety of the medication in several audible gulps. “GLK! GLK! GLK! GLK!”

“Oh my…” After the shock of the moment settled down, Twilight regrew her devious grin to match her blush. She grabbed the empty bottle with her magic, while Spoiled Rich hung her head and gasped frantically. Remnants of the purple mixture were still on her lips, and her breaths were laced with a strong grape flavor. Of course, Twilight’s eyes quickly trailed back to see the mare’s diaper in wait. “Hmmm… before I hold up my end of the deal, I’m curious to ask…”

Spoiled tried to stand back up, but froze when Twilight asked with an eager smirk: “... How long have you been dealing with that little… constipation problem?~”

“... uhhhh…” Her blush quickly deepened in realization, especially when she noticed the bottle floating freely in Twilight’s aura. Her pupils shrank when she finally saw the warning labels without obstruction. Even if it wasn’t extra-strength and instantaneous, Spoiled knew that chugging the whole bottle put her in serious trouble. But alas, even as her heart began to race in fear, her muzzle shakily opened to give an honest answer. “I… I-I haven’t… I haven’t gone in three days…”

“Ooh, perfect!” Twilight tossed the empty bottle aside, and lifted up Spoiled Rich with her magic. She quickly turned the mare around, and placed her right in the middle of the room with her padded rump facing her. Twilight used a quick teleportation spell to settle back in her seat, and she leaned back behind her desk gloatingly. “Oh, this is going to be good~”

“W-WAIT!! Mnnnffffff…” Spoiled Rich groaned and hung her head, but she couldn’t move her hooves while Twilight’s magic planted them to the floor. Since the belt was still going without pause, she ended up thrusting the air and twerking her diapered ass in front of the Princess. Due to how frantically she was convulsing, that bottle of laxatives was basically working the same way as an unopened carbonated drink being vigorously shaken. Even with her lumbering moans and crinkly padding, Twilight was able to overhear the distinct sound of some muffled, gut-churning gurgles already…

“Aaaahhhh!!” Spoiled tried to lurch down, but all she could do was instinctually squat her ass closer to the floor. “Oh no… Oh no, oh no, oh no, oh no…”

“Hehehehehe~” Twilight propped her hind legs on the desk, and sat comfortably to contrast with Spoiled’s current state. Even from a few feet away, she could tell that the bottle she chugged was putting her in some massive intestinal distress. Spoiled Rich clenched her eyes shut, but the same couldn’t be said for her bowels while that diaper was keeping her legs spread apart. She lowered herself as much as she could, but her trembling hooves remained standing so Twilight could see every inch of that white padding. The Alicorn bit her lip with a pent-up groan, and she shivered before purring out, “Come on, Mrs. Rich… I know you wanna do it~”

“Mnnnghhh!! N-NO!!” Spoiled sounded legitimately offended that she would even claim such a thing. Unfortunately, she couldn’t say much before another harsh growl erupted from her stomach. The mare’s belly visibly ripped beneath her shirt, while her tail flagged up instinctually. She tried her hardest to clench, but it was basically fruitless when she could feel those floodgates crumbling already. The laxatives were taking instant effect, making it feel like a power washer was about to go off inside of her. And even as she cried out in horrified dread, Spoiled Rich’s body got into an undignified squat. “GnnnnNNNAAAAAHHHHH!!!”

After days of constipation, Spoiled Rich felt an instant wave of relief and intense pain at the same time. Without even needing to push, the mare’s bowels erupted without mercy as she unloaded into her new diaper. The sounds of her disgusting squelches and gas were covered up by her lumbering shriek, which then turned back to a forced moan while the belt continued to vibrate against her nethers. The back of her padding instantly began to balloon out, swelling from the hefty mass that pushed the diaper to its limits within seconds. That white plastic quickly began to morph into a deep, lumpy brown as she kept going, unable to stop the mudslide that left her face pressed against the cold floor.

“AaaaaAAAAHHHH!!!~” The mare was still convulsing in arousal while messing herself, but not enough to actually reach climax from the ordeal. The belt was still edging her beyond reprieve, leaving her fur standing on end and her face visibly sweated. Her diaper continued to bloat out, soon becoming heavy as the sagging mass dangled between her legs. The mare was left shaking intensely as she kept moaning under her rapid breaths, and her bowels emptied out without pause into her padding. And all the while, Twilight Sparkle watched with a smug grin as she relished in the mare’s comeuppance; the sight of her messing was so satisfying, that she even conjured out a camera to take several candid pictures of the action in progress.

“Mmmmmm… that’s a good girl~” After sighing in vindictive pleasure, Twilight lit up her horn so she could hold up her end of the bargain. Spoiled Rich was still soiling herself rather badly, but that wasn’t enough to deter the Princess as she sent a small zap to the mare’s nethers. “There you go… The belt is still going, but I cut it down to half its intensity~”

She also used that moment to undo the mare’s bondage, allowing Spoiled to fall to the floor. She was unlucky enough to fall back on her ass, eliciting a nasty squish as she landed right atop that mound of filth inside of her diaper. She cried out with a disgusted wince, but could only shudder as she felt that mushy warmth spreading across her ass and privates. By the time she managed to roll onto her side, she groaned when she looked down and saw that garish brown had spread towards her crotch from the back. The back of her diaper was visibly flattened, but there was a lot of lumpiness and uneven coloring all over. While the mare was sprawled out in embarrassment, unable to even open her eyes or speak, a couple more flashes went off from the camera floating in Twilight’s magic.

“Ooh, these will make wonderful additions to my collection!” Twilight giggled cheekily as she watched the photographs develop out of the camera instantly. In a matter of minutes, the candid pictures of Spoiled Rich’s diaper usage were laid out on the desk beside that large folder of blackmail. She could hear Spoiled groaning to herself weakly on the floor, but she focused more on placing those lewd pictures in the dossier. “Don’t worry, I won’t share around these pictures yet… in fact, if you can manage to handle the rest of this week with that belt, I might consider tossing this whole folder in the fireplace in front of you.”

Spoiled tried not to groan while averting her eyes from the Princess’ cocky smirk. Despite the plethora of horrible names and insults she had brewing in her head, it wasn’t like she could sound too intimidating while wearing her used padding. So instead, she merely sighed and muttered in defeat. “I… I’ll be sure to… r-remember that… T-Thank you.”

“Hmph~ You’re welcome.” After spending years in Ponyville, and witnessing the mare’s Karen-esque behavior for so long without repercussions, Twilight didn’t feel too bad about the messy aftermath she forced her into. In fact, while Spoiled Rich remained lying in her own filth, the Princess took that moment to add another rule for the mare’s punishment. “You know what? If you want that belt’s intensity to be lowered even more, I would consider it in exchange for you doing another show like that~”

Spoiled cringed and gritted her teeth, clearly not wanting to add to whatever sick fetishes the Princess was imposing onto her. Unfortunately, even after being given a gracious lowering of the belt’s vibrations, she was still writhing with string twitches each time her pussy convulsed inside the confines of that belt. The stimulation was notably weaker than earlier, but that didn’t mean too much when she was still being edged so mercilessly. Spoiled hated to admit it to herself, but she had a feeling that this very arrangement would have to be considered if she had any chance of making it to the end of the week unscathed.

“Hehehehe~ Of course, I should warn you right now,” said the Princess with a malicious grin on her face. “If you do decide to use another diaper in front of me, I’ll be sure to have some outfits on the ready to inclu--”

“Hey, Twilight?” Without warning, Spike opened the door to the office and walked in. He was staring at a clipboard in his claws while addressing her. “I just wanted to clarify about a meeting with the Hippogriffs next Tuesday. Did you want your apology to Queen Novo to be in public, or in private face to…”

The dragon’s words trailed off as soon as he looked up from his clipboard, and saw the pandemonium before him. Spoiled Rich was still lying on the floor with her eyes bulged wide-open, looking like a deer in the headlights in mortified silence. Twilight was equally frozen while seated at her desk, with a massive blush that practically exploded across her face. Since Spoiled was lying in her own mess with her muzzle agape, the Princess could only try to giggle nervously at what her assistant just caught them doing. And judging by the wide-eyed, confounded stare he had on her, it was obvious that he wasn’t supposed to see any of this going down.

“... face?”

Twilight’s forced smile turned to a shameful wince, and she had to look away from Spike guiltily. Spoiled Rich couldn’t move an inch, but she tried her best to shoot the dragon a pleading look in hopes that she could be saved from this torment. Spike stared between them for a few seconds, and eventually face-palmed with his claw.

“Uggghhhhh… Darnit, Twilight! Not again!”
