Spoiled Rich's Punishment

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!”
