Twilight makes Rainbow Dash argue her case for why she isn't a nerd.

Rainbow Dash has maybe been a little too enthusiastic in her pranks and now Twilight keeps calling her a nerd in revenge. Now she's challenged Rainbow to convince her to stop.

A story I wrote in response to the absolutely amazing art I got from Kammy in the Ponysuits discord server's secret santa event. Features hypnosis, nerdification and wedgies, as is appropriate.

Rainbow Dork

“Look, Twilight, I get it. And I’m sorry and stuff. Now can you knock it off and just give me the new Daring Do book so I can leave?”

Rainbow grumbled but definitely didn’t pout. So maybe she’d been going a bit overboard with the pranks in the last weeks and maybe she’d made a slightly unflattering comment about how much of an egghead her friend was when she’d confronted her about them. But even if Twilight calling her a nerd had been kinda funny and maybe deserved the first time, in context, it was totally old and played out by now.

“Oh? You want a new book, like a neeeeerd? Do you need some reading glasses, too?”

Rainbow glared at her friend’s stupid smug smirk, as if she thought that running a single joke into the ground made her hilarious. The unicorn was even waving an actual pair of glasses around in her magic. Where did she even get those? Nopony their age in Ponyville even wore glasses, had she bought them just for her stupid running gag?

Rainbow huffed and crossed her arms, turning away to show how annoying that routine was getting. “For the last time, Twi… I’m not a nerd!”

“Hmm… tell you what, Dash. List all the reasons I’m wrong, and I’ll reverse my claims.”

Rainbow paused, frowning as she needed a second to remember what ‘reverse my claims’ meant. Ugh, of course Twilight would even make proving that she was not an egghead sound egghead-ish. And demand she make a stupid list like a nerd to do it, too. If Rainbow thought that the unicorn had it in her, she’d suspect some kind of gotcha in that, but the joke was starting to annoy her enough that a stupid gotcha couldn’t make it any worse, and was worth the chance of actually getting Twilight to stop.

“Fine!” Rainbow turned her head to look at Twilight again. “I’ll do your stupid list, but that doesn’t mean tha- ahhh!”

She yelped and nearly fell over backwards in surprise as something landed on her muzzle, blocking her vision. Or… not actually blocking her vision, just making it look kinda funky? Rainbow scrunched as she realized that Twilight had dropped those stupid glasses on her. And they weren’t even good glasses! They were smudged and blurry with some kind of spiral pattern of colored glass or something that caught the light every time she moved her head the slightest bit, forcing her to squint to see through them and making it hard to focus on glaring at her friend’s stupid smug purple face. She reached up with her forehooves to take them… reached up to… to… uhm…

“W-what was, uhhh… what was I…?” She blinked and shook her head with a groan, dropping her hooves again for balance as doing so made her dizzy, trying to remember what she’d been doing before that weird dizzy spell.

“You said you were going to list all the reasons why you’re not a nerd, remember?”

“Huh?” Rainbow squinted at Twilight, or at least at the Twilight-shaped purple blob she could make out, almost shaking her head again to clear it but catching herself just in time before she could make herself too dizzy again. She paused to sit still and blink rapidly until the room stopped ~~swirling~~ spinning, eventually giving it up as good enough.

“R-right, I was…” She focused through the dizziness, very carefully nodding to herself. “The reasons why I’m not a nerd, right. Well, first off, I’m the best flyer in town. I exercise every day and I bust more clouds than the rest of the town’s weather team combined.” She started to pose proudly, only to stumble and nearly faceplant as the sudden movement made her dizzy again. “T-that’s, I mean. That’s not something any nerd would do. They all sit inside with their books all day.”

The purple probably-Twilight blob nodded. “That’s a good point. But there are some nerds who exercise. I mean, I beat both you and Applejack at the Running of the Leaves, remember?”

“That didn’t-!” Rainbow stumbled and wobbled again as she’d instinctively jumped up to defend herself. “I-I mean, me and AJ tripped each other up all race, that was just a fluke!”

“But I still came in fifth place. That’s objectively a good showing.”

“F-fine! I guess!” Rainbow grumbled and gathered her scattered thoughts again, eyes flitting back and forth for a moment as she looked for a better argument. Which wasn’t easy, because she’d thought that was her best. “Uhm… I don’t read much. I had to be stuck in a hospital to even start reading Daring Do. And I never study! You sit me at a desk in front of a blackboard and I’ll be fast asleep in less than a minute.” She crossed her forelegs and grinned perhaps a bit too proudly at that point.

“Hmmm… I suppose that’s a point, but when was the last time you tried studying? Or reading any other books. You didn’t think you’d like Daring Do and we know how that turned out.”

Rainbow grumbled and glared at Twilight. “You can’t just say that maybe I’d like it if I tried. That’s one of those hypowhatsits. I don’t read and I don’t study, period.” She huffed and crossed her forelegs again.

“Fine, fine, I’ll give you that one.” Twilight giggled. “So that’s one. Got any other arguments?”

Rainbow had been having an argument with her for over ten minutes now. She chuckled at her own pun before quickly biting her lip with a squeak. Rainbow Dash didn’t do puns, wordplay was for nerds. She groaned and rubbed her cheeks with both hooves, trying to focus through the increasing dizziness to find some other reasons for her list. That was the problem with being so focused on one thing all the time, she supposed. She spent so much time flying and training that the only other things she did most days were normal stuff, and since they were so ‘normal’ it made it harder to remember specifics when she was put on the spot. Rainbow blinked and squinted again. Maybe instead of thinking of things she did she should think of things that were typical for nerds, to prove that she didn’t do those.

She ran her tongue over her teeth as she thought. Wait… teeth? Wasn’t there some joke about nerds and teeth? She perked up and opened her mouth to show her pearly whites. “Oh yeah! I got perfect teeth! Nice and white and straight and-” Her vision flickered and flashed as the spirals in her glasses suddenly lit up, glowing and spinning and changing colors as they filled her vision. Her mind blanked and her mouth went slack, hanging open as she sat there dumbly staring into the swirls. Somewhere behind the spirals, the purple blob was coming closer and something glinted in the light, before suddenly she felt something pushed into her mouth and pressing against her teeth.

“...”

“...”

“...ai…ow? Rainbow? You were saying something?”

“Whu…?” Rainbow blinked, staring at Twilight in confusion ~~through the dimly glowing swirls filling her vision~~. She blinked again, her brain rebooting and going back to the last thing she remembered “I wath… uhhh… nithe and white and… r-right! My teeth are nithe and thtraight thankth to my big ththiny bratheththth.” She blushed and wiped the drool off her muzzle with a foreleg. “Thorry…”

“It’s alright.” Twilight blushed as she wiped her own face dry. “It was my own fault for standing so close. A-anyway, you were saying?”

“Uhh…” Rainbow ran her tongue over the shiny smooth lengths of wire covering her teeth and the little gemstones bedazzling them in all the colors of her mane. “That’th right! Nopony but a big nerd would have big ththiny brathethth like thethe.” She sat up straight and puffed her chest out proudly, ignoring the bit of dizziness it caused.

Twilight snickered. “Oh, that’s a good point. Anything else?”

“Of courthe! I got lotth more points for my litht of reathonth why I’m a nerd.” Rainbow paused. “Ackththththually-” She paused again to wipe her muzzle. “Nerdth love making lithtth, so that’th another point, write that down too.”

Twilight snickered again, pulling a scrunchie out of a bag and walking around Rainbow to get behind her. “I’m not writing these down for you, silly.”

“Well, you ththould.” Rainbow pouted, still staring at the spot where Twilight had been and ignoring as her friend started to bundle her mane up to pull it into a ponytail. “Anyway, I altho got these big dorky glathththeth.” She wiped her muzzle again before adjusting her glasses. “They’re definitely totally nerdy. You can’t wear glaththeth like thethe and not be a big dorky nerd.”

“Hard to argue with that.” Twilight giggled, stepping in front of Rainbow again and changing the front of the pegasus’ mane style to look like hers with a flash of magic. “I can certainly say that I haven’t seen glasses as dorky and nerdy as these since my friend Moondancer. Lift your hoof please.”

“And my mane!” Rainbow pointed at her head before putting her hoof back down so she could lift her left hind leg, letting Twilight pull a pair of stretchy latex briefs over it. “I got the thame manethtyle ath the nerdietht pony I know!” She lifted her other hindleg for Twilight, swishing her tail as the briefs were pulled up into place. “And thith totally dorky ponytail to go with it, too.”

“I’m flattered.” Twilight huffed a little at the insinuation, stepping back in front of Rainbow. “Anything else you’d like to mention?”

Rainbow blinked and straightened up. “Of courthe! I even wore my geekietht Power Ponieth briefth today!” She turned around to wiggle her butt at Twilight, showing off the shiny underwear with pictures of the Power Ponies scattered across them.

“Oh my, those certainly are geeky.” Twilight smirked and pointed at the floor next to Rainbow. “But you didn’t have to take off your pants to show them off, did you?”

The pegasus followed her hoof, squeaking and blushing as she saw the pair of baggy pants with extra big pockets discarded on the floor. She quickly picked them up, struggling clumsily to put them on. “I-I jutht wanted you to get an eththtra good look at them, ith all.” A rustling of fabric made her look to the other side to find her nerdy office shirt left on the floor as well. She grabbed it without question, squirming into the sleeves and fumbling with the buttons while Twilight used her magic to tie the bright red bowtie around her neck and adjust the colored pens in the shirt’s chest pocket.

She finally closed the last button and relaxed, sitting back down with a proud smile and a light blush. “T-there. B-but don’t ththanthe the point again. The important thing ith that I’m wearing all of thethe nerdy clotheth becauthe I’m a total nerd.”

Twilight giggled at her before putting on a serious face. “Wow, Color Theory. I guess I was wrong, you really are a nerd.”

~~Rainbow Dash~~ Color Theory blinked before smiling wide enough to show off her shiny braces and dimple on her cheeks, tapping her hooves together. “That’th right! I’m the thmartetht, dorkietht nerd around~!”

Twilight nodded. “I’m glad we cleared that up. Let’s get back to equations, shall we?”

“O-oh gothth, I can’t wait!” Color Theory gasped and nodded excitedly, following after Twilight as the unicorn led her around some bookshelves to a corner where a desk and blackboard were set up.

“I already prepared some worksheets for you. I know how much you love studying.” Twilight pointed at the sheets of paper left on the desk, full of equations… mostly simple addition and subtraction along with some basic multiplication, since even turning her friend into a nerd had some limits. Color Theory didn’t seem to mind or even notice though, staring at the equations like Hearth’s Warming had come early and immediately sitting down to get to work, pulling one of the pens from her chest pocket.

“That… and that ith… gothth, thome of thethe are difficult… p-perfect for a big thmart nerd like me.” Color giggled, squinting through her glasses and sticking her tongue out in concentration.

“Oh, but we almost forgot the most important part of studying~” Twilight grinned and trotted around the pegasus.

“The motht iiiieeeeeeee!” Color Theory squeaked and squealed in surprise as Twilight’s magic grabbed the back of her underwear and yanked, the rubber briefs easily stretching out enough to be pulled all the way over her head and face.

“Mmmmf! Mmmh mmmmpf!” Color yelped and flailed, almost falling over as she fought with the briefs, tugging at them until she managed to pull them off her face, leaving them still stretched over her ears and forehead. She looked around dizzily, blinking and squinting in confusion at the way her vision was clear and crisp instead of blurry and swirly. Finding her glasses on the floor in front of her she quickly picked them up, fumbling to get them back onto her muzzle and relaxing as the swirls filled her vision again. She blushed and pouted, turning her head to glare at Twilight. “T-that wath mean, Twilight!”

“Hmm? What’s wrong? Nerdy dork students like you get wedgies, don’t they~?” Twilight snickered at her.

“T-that’th… I-I mean…” Color blushed and squirmed, unable to think of a good counter to that. Nerdy dork students did get wedgies. She reached up to try and pull the briefs off her head entirely, but a nerd like her wasn’t strong enough to do that. “O-okay, you gave me a wedththie. C-can you at leatht help me take them off again now? Thitting like that ith embarraththing.”

“Hmmmm… I might consider it once you finish your worksheets.” Twilight smirked at her.

“B-but… but I…” Color whined and blushed, cheeks red as she leaned forward to try and focus on her equations again. She bit her lip when the movement made her briefs stretch a bit more, the feeling of them stretched over her head and the way they pulled at her crotch and her flanks reminding her of what a huge nerd she was.

Twilight watched her while she worked through all of the equations, taking the sheets away once the pegasus was done. “There we go~! That was some nice nerdy fun, wasn’t it? Now did you want me to help you with that wedgie or did you want to move to today’s lecture right away?”

Color blushed and wiggled her flanks, biting her lip at the way her stretched out briefs were pressing and rubbing against her wet and heated marehood. “W-we can t-thtart the lecture firtht. I-I wouldn’t want to hold up clathth…” She sat up a bit straighter and bit back another moan, excited to listen to a lecture like a total nerd and smiling as the spirals on her glasses spun a little faster.

“Wonderful~!” Twilight grinned as she walked over to the blackboard, picking up a piece of chalk in her magic and writing “AWESOME” on the board. “This is the first in a series of lectures about coolness. If you pay attention, even a total nerd like you might be able to become cool someday.”

She smirked as ‘Color Theory’ perked up and leaned forward attentively. A few days (or weeks) as a nerd should help fix Rainbow’s attitude, but in the meantime she had a lot of lectures prepared for the pegasus.

~~~~~

Rainbow Dash grumbled to herself as she slipped into the library, closing the door behind her and locking it just in case before taking off the coat she’d been wearing to cover her distinct mane and tail.

“Oh hello Rainbow Dash. What brings you here today?” Twilight stepped into view with an innocent smile.

Rainbow glared at her. “I’m only here because I finished the book I borrowed.” She pulled a primer on statistics out of her coat before blushing and pulling out a pair of dorky Ogres&Oubliettes themed boxers as well. “And because I found another one of those stupid things you made me wear during that week and wanted to get rid of it.”

Twilight giggled before quickly covering her mouth. “Sorry, sorry. I shouldn’t laugh at that.”

Rainbow glared a little harder. “It’s not funny! Ponies are still laughing and calling me a nerd because of that stupid prank you pulled. I’m not a nerd, I’m supposed to be the coolest pony in Ponyville!”

“I know I went a bit overboard with that. I apologize, again.” Twilight hummed as she took the book and the boxers from her friend. “Did you just want to return this or do you want to borrow a new book while you’re here? I have a textbook on pegasus history that I think you’d love.”

Rainbow blinked and paused. Reading a history textbook sounded incredibly boring but cool ponieth alwayth read the bookth their thmart friend Twilight recommendth to them. That was the reason she knew about statistics now after all. “Fine. I guess I’ll take it with me, but that doesn’t make me a nerd.”

“Of course, of course.” Twilight nodded quickly, floating over the thick book for Rainbow Dash to stash in her coat. “I really am sorry about that, promise. In fact, I bought you an apology gift!” She pulled out a small box, holding it out to Rainbow.

“An apology gift? This isn’t like those glasses, is it?” Rainbow gave Twilight a suspicious look before carefully opening the box, holding it away from her. After a few seconds of nothing happening, she fully took the lid off, gasping at what was inside.

“A pair of Wonderbolts panties?!” She quickly pulled out the panties and dropped the box, stretching the blue and yellow rubber between her hooves and grinning because Wonderboltth merthth ith alwayth awethome! She immediately bent down to pull the panties over her hindlegs because cool ponieth alwayth immediately try out any giftth their friend Twilight giveth them, pulling them up until they sat snuck against her flanks. “These are awesome! It doesn’t make up for that stupid prank, but it’s a start.”

“I’m glad you like them.” Twilight smirked as she sat down on a pillow and slowly spread her hind legs with a light blush.

Rainbow blinked and stared at the unicorn presenting herself before nodding and trotting forward. Etiquette leththon #4: if Twilight giveth you a gift, it’th only right to properly thank her. She leaned down to push her face between Twilight’s hindlegs and dragged her tongue over the other mare’s marehood. “This doesn’t mean I’ve forgiven you for that prank, I’m only being polite.”

“O-of course~!” Twilight moaned and giggled, leaning back a little to give Rainbow better access. She looked down at the pegasus for a moment before smirking and lighting her horn, grabbing the back of the Wonderbolts panties and giving them a yank.

Rainbow yelped and stumbled forward as her butt was yanked up and the panties stretched out. She made to say something when the fabric was yanked and stretched again, snapping over her eyes and covering the top of her head. She whined and wobbled, blushing at the tight rubber over her head, making her feel like a total… like some sort of…

Color Theory moaned, squirming against the wedgie as she wiggled her flanks to make the rubber stretch and pull.

“Is everything alright, Color Theory? You seem a bit distracted~”

“N-no Mithth Twilight!” She squeaked and quickly leaned down again, blushing and moaning as she continued eating out her friend to thank her. She continued to squirm and drip against the panties, the tight rubber over her head making her feel dizzy and giggly by the time she finally pulled back with Twilight’s juices dripping off her muzzle.

Twilight smirked as she lazily cleaned the pillow with a spell, panting softly. “You’re getting better at that, Color Theory. All those etiquette lessons must have really helped.”

“T-thank you, Mithth Twilight. I’m alwayth happy to learn.” Color giggled and squirmed at the compliment.

“Oh, but did you get mixed up this morning? That doesn’t look like your usual underwear.”

Color blinked and squinted against the light as the rubber was pulled off her head, moaning as it snapped back against her flanks. She looked down and gasped at what she was wearing. Real Wonderbolt panties? Those were way too cool and awesome for a dorky nerd like her! She quickly squirmed out of them, gratefully taking the bootleg Supermare boxers Twilight offered her instead. The unicorn was soooo thoughtful to keep a spare set of underwear around for her dorky nerd friend.

She sighed and relaxed as she pulled the boxers up over her flanks, making sure they sat right. Now she looked properly nerdy again.

“There we go. That fits you much better.” Twilight giggled, walking around Color and slapping her flanks with a hoof, making the pegasus yelp and jump. “But we still need to do something about those super cool panties you were wearing, don’t we?”

“What do you- eep!” Color squeaked as the shiny blue and yellow panties floated up and pounced at her face, moaning when they pulled themselves over her head until her ears were poking out of the leg holes and her muzzle was filled with the smell of latex and her own earlier arousal. She squirmed and tugged weakly at them, blushing bright red under the fabric. “I-ith thith really…?”

“It’s perfect~! You look like you just got away from somepony bullying you.”

“Nerdth get bullied…” Color blushed and moaned, nodding along dizzily and taking deep breaths of the rubber.

“Exactly. Now, was there anything else you needed, Rainbow Dash?”

“Wh- huh?” Rainbow Dash blinked and wobbled, shaking her head dizzily. “I, uhhh… I don’t think so?” She blinked again before remembering that she was still mad at Twilight and giving her a glare. “R-right, yeah. I’ll just be taking my book and heading back home.”

She wobbled back towards the front door, pulling the cloak over herself before stepping outside and taking flight. She’d just head home, make some dinner then read some chapters of her new book before bad. She took a deep breath and blushed, moaning softly from the strange smell in her nose. Maybe she’d spend a few minutes masturbating to the thought of getting bullied. Not because she was a huge nerd or anything, but to remind herself to pay attention and not fall for any of Twilight’s pranks again.
Huffing and puffing ~~into the latex over her nose~~ as she landed in her home with a flush on her face and nodded to herself, one hoof reaching over to yank at the back of her dorky boxers. She’d just have to remind everyone that Rainbow Dash was the coolest, most awesome pony around, and cool ponieth bully dorky nerdth like Color Theory. She giggled to herself and moaned as she pulled the boxers over that dumb nerd’s head. “T-that’th going to ththow Mithth Twilight…”
