Rainbow's Curse

Fluttershy approached the door to the library, cautiously looking around. Nopony was there, but Twilight had warned her that she should be as discreet as possible, and so she wanted to be extra special careful that nopony saw. She wouldn’t want Rainbow’s secret to get out, that would be so embarrassing for her.

Tapping on the door with a hoof once she was sure nopony was watching, Fluttershy said, “Um, hello?”

No answer came, but that wasn’t a surprise. They were probably busy, she could come back later. Twilight had said to show up early, but maybe they were still asleep, or busy, or had changed their minds… She would wait a little bit and try again in a little bit.

“Now, Rainbow Dash, hold still!” Twilight’s voice was just barely audible through the door, but Fluttershy had keen ears, from years of talking with bunnies and beavers and other little forest creatures with their soft voices. “This is for your own good!”

“Ow!” Rainbow’s cry of pain was obvious and clear, as was the sound of a hoof smacking against something. “That really hurt!”

“That’s the point,” Twilight said, sounding stern. “If it doesn’t hurt, it won’t accomplish anything! Stop- Squirming!”

“OW!” Rainbow Dash yelped again, sounding really hurt. Fluttershy chewed her lip, looking from side to side and trying to decide what to do as Rainbow said, “I’ll stop squirming when you lemme up!”

“Your diaper leaked all over my bed, Rainbow Dash, I’m not letting you up until I’ve finished your spanking. Or don’t you want me to change your diaper? Because you’re not getting a change until this is over!” Twilight sounded stern and a little annoyed as she said it, and Fluttershy heard another collision of hoof against… Something. Probably Rainbow’s diaper. “Why didn’t you sleep in the guest room? I put a plastic sheet down just in case this very thing happened!”

“OW OW OW!” Rainbow Dash repeated, starting to cry. Fluttershy couldn’t take it any more. She didn’t like to invade their privacy, but Twilight was just being too mean to Rainbow Dash. Kicking down the door, she saw a bizarre tableau. Twilight was sitting in the center of the room on a low chair, a clothespin on her nose, and over her lap she was holding Rainbow Dash down with a hoof. Rainbow herself was wearing a blue and gold foal’s onesie, or at least something resembling a blue and gold foal’s onesie.

The sleeves were short, the neck formed a V shape,. A gold ribbon was pinned to the front, with a matching blue pacifier dangling from the end, and on the side the words ‘Wonderbolt in PottyTraining’ written on the side, the word ‘Potty’ crossed out by what was supposed to look like a crayon, as though the foal wearing it had tried to cover it up. Decorating the flanks, a similarly fake crayon drawing of a lightning bolt and pair of white wings were emblazoned, in a foalish redesign of the Wonderbolts logo. The onesie, altogether, looked quite like a Wonderbolts uniforn redesigned to be worn for a foal, albeit a foal the size of a full grown pegasus. Around Rainbow’s crotch the fabric was clearly wet, and Rainbow’s fur also seemed damp, no doubt from when her diaper leaked as Twilight had mentioned. Fluttershy also noticed that the flap on the onesie was unbuttoned and dangling open, revealing Rainbow’s rather disgusting diaper beneath. The smell wasn’t too horrendous, but it was bulging out visibly from its contents, and it was so soggy that Fluttershy was surprised that the diaper hadn’t simply given up and fallen off from the weight. Rainbow was bawling into her hooves, visibly shaking.

“Twilight Sparkle!” Fluttershy announced, eyes narrowing. Nobody hurt her friends, even other friends. “You let Rainbow Dash go right this moment!” She knew that the curse had put Rainbow into diapers and foalish clothing, but that didn’t mean Twilight had to treat Rainbow like a foal. Stalking forward angrily, Fluttershy gathered her will to give Twilight a stern talking to.

“Fluttershy!” Twilight said, looking a little surprised to see her. Pushing Rainbow off her lap, the pegasus just crumpled to the ground next to her, crying. “I didn’t hear you knock.”

“I’m disappointed in you!” Fluttershy said, now only a step away from Twilight, taking the unicorn by the shoulder and making her get to her hooves and leading her to the other room so they could talk in private. “This is no way to treat your friend! You know better than anypony that she can’t do anything about her accidents, you shouldn’t be mad at her for having an accident and leaking on your bed.”

“But- Fluttershy, wait!” Twilight said, trying to slow their progress as Fluttershy pushed her towards the kitchen. She even drove her hooves into the floor, but Fluttershy angry was not somepony who you could easily slow down. “I can explain! Stop!”

“No buts,” Fluttershy said, sternly pushing Twilight through the door and into the kitchen. “There is no excuse for hitting your friend like that, especially since she’s already so embarrassed about having accidents! Now, you are going to tell me why you are so mad, and then you are going to calm down a bit, go back in there, and apologize to Rainbow Dash for hurting her!” She finally stopped to take a breath, a little of the energy going out of her. Rainbow was safe now, Twilight had stopped spanking her once Fluttershy came in, so as long as they took a few minutes to calm down and Twilight apologized, things would be okay. Still… “And you shouldn’t make Rainbow wear her diaper once she’s had an accident, it’s bad for her. Threatening not to change her until she gets a spanking is just cruel!”

“Fluttershy!” Twilight exclaimed, glaring back. “I had to spank Rainbow Dash!”

“No you didn’t,” Fluttershy said, shaking her head. “Hurting somepony else never solved anything!”

“Yes, I did!” Twilight insisted, her tone nasally from the clothespin on her nose. “Because the curse won’t let me take off her onesie unless I spank her first!”

Fluttershy paused as she opened her mouth, hesitating as she registered what Twilight said."I- Um… Oh…” She mumbled, confused. “I’m sorry. I… I guess you should go change her, then, I’ll just w-wait here I guess. Sorry.”

Putting a hoof to her forehead, Twilight sighed. “Well I would, but I’ll have to start the spanking all over again.”

Things were starting to make sense, as Fluttershy realized why Twilight had been reluctant to leave the main room a moment ago. “Oh…” She mouthed, blushing and feeling a little stupid. “I’m sorry.”

“It’s fine, you didn’t know,” Twilight said. “We were about to have breakfast, can you set the table while I start this over?”

“Okay,” Fluttershy agreed, nodding quickly. She felt bad, and if she could help out at all then she would.

Twilight re-entered the living room, trotting back over to the sniffling Rainbow Dash and putting a hoof on her shoulder. “Hey there, Rainbow Dash,” she said, comfortingly, as she removed the pacifier from between Rainbow’s lips, letting it dangle from the ribbon. “How’re you feeling?”

Trying to bring up her snark shields, Rainbow said, “My butt hurts, whadya think? Can’t you just freakin’ change me already?” It was a little harsh, but Twilight understood why Rainbow might be a little sensitive at the moment.

“Well, er,” Twilight started, unsure exactly what to say. “When Fluttershy came in, she… Marched me into the other room.”

Rainbow raised an eyebrow, confused, aher eyes went wide in realization and she looked down at her crotch to see the yellow-gold flap buttoned squarely back in place, the loaded diaper bulging out beneath the fabric. “B-but…” She stammered, horrified. “We have to do that again?”

“Sorry,” Twilight said. “We can wait a little bit if you need some time, maybe get you changed after breakfast. How does that sound?”

Rainbow considered it. Her butt was stinging badly, she didn’t know if she could take another spanking like that right away, and as she sat up she felt a tingling that reminded her a messy diaper really wasn’t so bad. She could put up with the smell until after breakfast. “It can wait,” she said. “What’s on the menu, more applesauce?”

Twilight nodded sympathetically. “Sorry, but unless you want to go back to foal food it’s that or nothing.”

Tugging at the rubber collar around her neck uncomfortably, Rainbow commented, “Eh, applesauce isn’t bad. Gets a bit old, but I don’t mind.” Up to her hooves, she headed towards the kitchen. Her waddle was pronounced but more fluid than before, it looked as though Rainbow had gotten rather used to walking with padding between her legs, and even the mush between her thighs didn’t seem to slow her down.

Impressed to see the table set with napkins, silverware, and even little serving trays when they walked in, Rainbow whistled. “Nice job setting the plates,” she said, almost making a crack about how Fluttershy had made her need another spanking. Remembering what had happened with Pinkie Pie, though, she decided not to comment. She didn’t need to make two friends cry in the same week.

“I’m sorry,” Fluttershy said anyways, as though Rainbow actually had chastised her. “Here, you wanted the applesauce, right?” She asked, quickly dishing some up on Rainbow’s plate.

“I don’t know if ‘Wanted’ is the word for it,” Rainbow replied, as Twilight took a seat at the end of the table. “But yeah, that’s for me.” Following Twilight’s lead, then, she took her seat where Fluttershy had placed it.

The moment her padded behind was in the chair, though, there was a flash of light and the circumstances changed. The seat morphed, growing taller, a wooden tray appearing over Rainbow’s lap. Her forelegs were pinned beneath the tray, rendering her unable to move them much, effectively trapped in the high chair. The back of her diaper was pushed into the chair’s seat, causing the mess smush to the sides and making the leaky diaper to trickle a little more urine down the back of her legs. Even as she shivered in pleasure, Rainbow grimaced.

“Ew ew ew!” She said, squirming in the high chair, which only made both her arousal and discomfort more intense. She hadn’t even noticed the bib now pinned to her collar, hanging over the onesie so that it wouldn’t get any stains on it.

Twilight and Fluttershy both looked over in surprise, seeing Rainbow Dash in her newest predicament. “Well,” Twilight said, a little amused. She’d hate to be in Rainbow’s horseshoes, but the curse was certainly well design to embarrass its victim. “At least it’s obvious how to get you out of this one.”

“Yeah, how’s that?” Rainbow asked, trying to pull her forelegs free from under the high chair’s tray.

“I think you just have to eat breakfast,” Twilight said, shrugging.

“Yeah?” Rainbow Dash said, jerking and wiggling in every way she could think of, accomplishing little. The wonderbolt-styled onesie felt restrictive, and between it and the high chair she was feeling downright claustrophobic. “And how am I supposed to do that? I can’t even move my- Oh, you are KIDDING me!” She shouted, as she saw the spoonful of applesauce levitating in front of her face.

“It’s not that bad,” Fluttershy said, trying to calm down her friend a little bit. “You told me that you always wanted a sexy mare to hoof feed you, right?”

“Well- Yes, technically,” Rainbow admitted, “But this is totally not what I meant! I was thinking something chocolate while we’re lying in bed, not- Wait, besides, Twilight isn’t even sexy!”

“Hey!” Twilight protested, a little miffed. “I’ll have you know, some ponies find intelligence to be quite attractive.”

“Yeah,” Fluttershy added on. “And Twilight really is very pretty!”

Rainbow and Twilight looked at Fluttershy, raising their eyebrows almost in unison.

“Uh… What.” Rainbow Dash questioned, her voice deadpan.

The spoon tilted slightly in the air and the applesauce fell from it as Twilight forgot about her levitation spell, leaving the sauce to splatter on the high chair’s tray. Blushing, Twilight asked, “You… You think I’m pretty?”

Fluttershy looked down at her hooves, her face awash with pink as she blushed. “Well- I, you see… Ye-”

“HEY!” Rainbow Dash interjected, feeling a bit miffed herself. “How come when you think I’m coming onto you it’s all ‘Oh, Rainbow, we’re just friends’ but when Fluttershy does it it’s all blush and schoolgirly stammer-Mpthbhphhp!” She was shut up as the pacifier was jammed into her mouth by Twilight’s magic.

“Fluttershy… I c-can’t really think about this right now, sorry, I really need to help Rainbow Dash. If this curse keeps getting worse, well… We’ll talk about this later, okay?”

“O-okay,” Fluttershy said, blushing even more. “I’m s-sorry, I didn’t mean to cause any problems…”

“Mmmbmbph!” Rainbow Dash protested, annoyed. “Wemah ouda vis’ fing!”

Twilight’s horn glowed and she pulled the pacifier away from Rainbow’s muzzle. “Don’t make a big deal out of this,” She warned, refilling the spoon. “Open up?”

“Fine,” Rainbow said, feeling a little silly at being fed, but with her hooves pinned there wasn’t much else she could do. Opening her mouth wide, Twilight’s magic moved the spoon towards her mouth, hitting its target… Mostly. At the last second the spoon wobbled, getting a bit of the applesauce on Rainbow’s face. Swallowing and frowning, Rainbow said, “Uh, my mouth isn’t a hard target. What the hay?”

“Sorry, I think the curse is interfering,” Twilight said, as she refilled the spoon. Trying again, she got the food into Rainbow’s mouth again, but the third spoonful ended up more on her chin than in her mouth.

It was hard to enjoy the taste of the applesauce when the stink of her diaper permeated the kitchen, but Rainbow Dash choked down every bite Twilight fed her. Hindquarters still stinging, she squirmed in the high chair every so often, but that didn’t help much more than making her horny, so she tried to show a little self control. By the time the bowl of applesauce was empty, her face and bib were both splattered with applesauce, and she felt overfull, but the high chair was still in place.

“What gives?” Rainbow Dash said, a little annoyed. “I thought you just had to feed me?”

“Here,” Twilight offered, her horn glowing as she retrieved an empty bottle from the cupboard and a jug of milk from the fridge, filling it and snapping on the rubber nipple. “You probably have to drink this, too.”

Rainbow Dash rolled her eyes and opened her mouth, letting Twilight levitate the bottle in place and suckling. It took a couple minutes, but as far as it went it wasn't that bad. She was thirsty anyways, and nopony was teasing her. In fact, the only noise was her suckling and the other two ponies’ chewing, so the time passed quickly.

Still nothing.

“Now what? You said that would do it!” Rainbow Dash complained, jerking again at the high chair.

“Well, that’s what I thought. Maybe there’s some other trigger?” Twilight theorized. “Something more juvenile and foalish.”

Quietly, Fluttershy started, “Um… Maybe…”

“What’s more foalish than being fed foal food in a high chair?” Rainbow Dash shot, exasperated. “You want me to say ‘Goo goo gaga’ a whole bunch?”

“Maybe…” Fluttershy started again, but she was cut off just as quickly.

“Or should I just start crying for mommy? Suck my hoof? Twilight, this is so stupid!”

Fluttershy was about to speak again, when Twilight’s horn glowed, jamming the pacifier one more into Rainbow Dash’s mouth. “Fluttershy is trying to say something,” Twilight told her, disapprovingly. “If you’d let her talk, she might have a good idea. Go ahead?”

“Well… I was thinking, maybe, does she need to be burped?” She offered, quietly.

Twilight looked at Rainbow Dash, and then back to Fluttershy, and then at Rainbow Dash one more time. Trotting to Rainbow’s side, she took out the pacifier and gave Rainbow a couple pats on the back.

“This is stupid,” Rainbow said, after the first couple pats did nothing. “It’s not gonna-” She was cut off by her own belch, and as soon as the burping was done the high chair vanished, leaving only the regular wooden stool that had been there a moment before… Half a foot below where Rainbow had been sitting.

With a yelp, the pegasus fell the six inches and landed with a splurchy noise, gasping as she felt the diaper’s contents shift between her thighs. “Um… Can you just get me changed now? My butt’s feeling a bit better.”

“Of course,” Twilight agreed, getting out of her chair and extending a hoof to help Rainbow up. “We’ll just be a moment, Fluttershy, and then we can get going.”

“Going where?” Rainbow asked, before turning to Fluttershy to add, “And please don’t drag Twilight away again, okay?”

Fluttershy blushed and looked down, a little ashamed. “I… Uh, okay…” she said.

Realizing she had upset Fluttershy, Rainbow hung her head guiltily, feeling especially bad when Twilight shot her a glare. Sulking, Rainbow trotted to the living room to get changed. With Twilight a second behind her, the pacifier re-appeared in her mouth, but she didn’t bother having Twilight take it out when the unicorn followed her in. She wouldn’t have much to say during the spanking, and there was no need for her mouth to feel crappy the entire time. Besides, it wasn’t actually that bad, and suckling it helped distract her from the rest of her outfit.

Pulling over a chair with a quick glow of her horn, Twilight sat down and patted her lap with a hoof, waiting for Rainbow to hop up. “I’ll try and get it over quickly,” she said, sounding apologetic.

Rolling her eyes, Rainbow Dash climbed up, shutting her eyes and  trying to brace herself for the inevitable. A second went by, then two, and just as Rainbow was about to turn her head to ask what was taking so long she felt Twilight’s hoof smack the seat of the onesie. Even with the diaper absorbing most of the impact, her already-tender hindquarters flared up in pain at the impact, and Rainbow’s eyes started to water. The next spank was a bit lower, hitting more of the diaper and hurting a little less. That was almost worse, though, and she had to suck hard on the pacifier and jam her eyes shut in an attempt not to groan in response to the pleasure she suddenly felt. Crying was embarrassing enough, but she wasn’t about to make Twilight think she was enjoying this.

No, it doesn’t matter if I AM enjoying this. Mercifully, the next spanking was far more painful, and as she yelped into the pacifier and a tear ran down her cheek, all thoughts of any personal fantasies being fulfilled practically disappeared. Though, if Twilight were to keep me bent over once the onesie comes undone and go a little gentler with her hoof against the back of the diaper, maybe- No! Stop thinking about that! Blushing furiously, she sucked on the pacifier and whimpered as Twilight spanked her again. The onesie gave in, then, blue snaps undoing the flap with a little ‘pop’.

Cracking one eye open, Rainbow Dash tentatively waited for a moment to be sure that Twilight was done. “Coow?” she asked, looking over her shoulder and noticing that Twilight was blushing almost as much as she was.

“Er… Yes.” Twilight Sparkle got Rainbow off her lap with a small push, making sure that Rainbow would land on her feet, before quickly standing and clearing her throat.

Even Rainbow was able to pick up on the fact that something was up, and she said as much. “Awe ‘ou otay?” she lisped.

“You were, er...” Twilight blushed. “Well, you were moaning.”

“Wh-wha’?” Rainbow felt the color drain from her face, mortified, desperately trying to think of a lie.

Pulling out the pacifier with a hoof, Twilight Sparkle shuffled her hooves and chewed her lip. “Er, when I was spanking you, you started moaning every time I, uh, hit you.”

Rainbow Dash blushed, shaking her head. “N-no I didn’t!”.

Twilight dropped the subject. “Let’s… Just lie down, okay?” She had no desire to have an awkward talk with Rainbow Dash about her sexual preferences or fetishes, and that conversation was getting dangerously personal.

Rainbow Dash had no problems doing as Twilight said, not wanting to admit herself that she had been so obvious during the spanking. It was the curse, though, once they got this over with she would be back to normal.

Lying down, Rainbow stared at the ceiling with her hind legs raised as Twilight summoned the changing supplies. Untaping the diaper, Twilight’s magic raced to get her cleaned up. It was like clockwork after so many times, and Rainbow was in a clean diaper and buttoned back in her blue-gold onesie before she could say a meme-worthy catchphrase.

Rubbing her flanks as she got to her hooves, Rainbow winced. “So, what’s the plan, exactly?”

Twilight smiled, sure that she had a winning idea this time. “We’re going to see Zecora.”
