Working with The Wonderbolts at times could be very hard for Rainbow Dash, especially that time her parents watched her. Once Rainbow Dash had finished with her flips and tricks, it was time for her to wrap up her performance. Deciding to end with a bang, she attempted to do a Sonic Rainboom. Spitfire may have preferred something a bit less dramatic, but it wasn't like Rainbow was trying to intentionally upstage anypony, this was her own solo performance, and she wanted to give it her own level of style and flare.
But, as Rainbow began to build up speed for the signature trick, her mind started to wander. She was a little distracted thinking about the things she planned on doing when she got back to Ponyville the next day (despite being a Wonderbolt, Rainbow Dash had some promises she vowed to keep). Among her plans, she intended to set aside time to help Scootaloo train to fly, and help Twilight with a few things at the castle. Not to mention the fact Starlight had said she needed help with picking out kites, which Rainbow found weird. And that didn't even begin to cover what Rainbow was looking forward to doing the most. "It's been such a long time since I've had some me time. There's this new relaxation technique I've been itching to try." She thought to herself.
Rainbow was so distracted with her thoughts, that she didn't notice until too late that she was veering off course! She tried to correct her position and realign herself properly, but couldn't stop herself and crashed into a pile of trash! Rainbow was fortunately dazed but unharmed, and she quickly tried getting the food off of her. To think that this was the second time this happened to her since becoming a Wonderbolt. "I really need to stop getting distracted. I've got a job to do. But at least none of the other Wonderbolts saw that." She said to herself, but her assumption turned out to be premature. Spitfire approached the young Wonderbolt with a bit of an annoyed look on her face.
"Rainbow Dash this is the second time you've crashed into something!" Spitfire lectured. "You seemed to be distracted by something. Mind telling me what was on your mind?" She asked.
"Oh no, what do I do?! I can't tell Spitfire what I was thinking about, she's sure to laugh at me, or worse, kick me off The Wonderbolts!" Rainbow Dash thought to herself, trying to resist the urge to fly off and attract unwanted attention. "Come on, Rainbow. Think, think, think!" Fortunately, she didn't have to think long for a convincing "excuse" to present itself. "Sorry, Captain," She apologized to Spitfire. "I was just thinking about the fact you're giving me the rest of the week off. You really sure I deserve it? I mean, I'm still the newest member of the team."
Spitfire bought the excuse hook, line, and sinker. "That may be so, Crash, but I've seen for myself how skilled you are," She replied with a knowing smile. "You've more than earned your place on the team, and ever since that crash landing during your big debut, your career's been going nowhere but up. Besides, I know how important you and your friends are. Princess Twilight specifically told me to give you time off in case any such situations arises. Don't tell me you're saying you'd rather I give your time off to somepony else?"
Rainbow Dash shook her head. "No no no, I'm fine with having the rest of the week off. Guess you're right, Spitfire. Besides, I have been feeling a little overworked. Maybe sometime alone at home will do the trick." She tried her best to look unhappy, but the truth was Rainbow was actually looking forward to going home. She'd been looking forward to trying that new relaxation method all week, even if it seemed a bit "unusual" and even "childish".
"Just be sure to wash off your uniform before too long," Spitfire advised, flying off while holding her nose. "Trust me, you DON'T wanna know what some ponies throw out with their trash." With that command given, Spitfire left Rainbow Dash.
Deciding it was best to end her performance before anypony could smell where she'd been, Rainbow flew back towards the crowd and just finished with a quick aerial signature. As she finished her performance and touched down, a smile slowly started to form on her face.
Rainbow just barely struggled to keep herself from squealing like an excited school filly, as she quickly zoomed to the private showers to hose off her soiled flight suit. As the warm spray removed any traces of stinky garbage, Rainbow mentally finalized her plans, while glancing at the clock resting outside the shower stall. She frowned a bit, as she saw what time it was. "Scootaloo should still be in school by now, and I doubt her folks would approve of her ditching, even if it is to get flying lessons from an awesome flyer like me," She thought. "I guess I'll have to help her later, or maybe the next day. But I guess I can visit Twilight, and then help Starlight with her kites. Then I can probably head home and relax. I mean Scootaloo can miss a day of training, especially if she's one of those unlucky fillies who's got curfew. We'll have all day tomorrow and the next day to work on her flying." Once she had properly showered off, and her flight suit was clean and smelling nice again, Rainbow Dash left the compound, lifted into the air, and took off back to Ponyville.
Once Rainbow Dash got back to Ponyville she immediately began thinking about her relaxation plans and what they involved. She'd read that diapers were a big part of it, which the brash speedster found odd. The only diapers she knew about were the kind foals wore, and the kind older colts and fillies wore to help with bedwetting. There had been rumors circulating in certain circles that the Wonderbolts wore diapers for long flights, but as far as Rainbow knew that's all they were, rumors.
Even so, Rainbow found that she couldn't stop thinking about the soft, crinkly, disposable undergarments. And although she'd already privately ordered and recieved a package of them she thought to herself. "l actually should pick some more up once I'm done helping Twilight and Starlight. I don't have as many as I'd like. I'll need to put a disguise on though first. I can't let anypony catch me buying diapers, that would be way too hard to explain."
The very thought of somepony catching her terrified Rainbow Dash to no end. She'd had nightmares about Scootaloo catching her and losing all the respect she had for her honorary big sister. Rainbow worried so much about this and many other possibly "What If?" scenarios, that she forgot to pay attention to where she was going. The next moment she looked, she had crashed right into Twilight's crystal castle, which hurt badly. Unlike Twilight's old house, she wasn't able to fly through the windows and crash into books.
Twilight immediately walked out and dusted Dash off. "Rainbow Dash, are you alright?"! Twilight asked with concern.
"I'm fine, egghead," Rainbow replied with a groan. "It's not like I broke anything."
"No, but you or somepony else could've hurt," Twilight commented and lectured. "You know, after all those lessons you gave me about paying attention to your surroundings, you could stand to practice what you preach. What if somepony got hurt because of your recklessness? What would you do then?"
"Hey, I'm not reckless!" Rainbow protested, even though she knew Twilight had a point. "I was looking where I was going, or at least I kind of was. I just…." Then she paused, realizing that if she mentioned she'd trailed off Twilight would surely ask why, and Dash was in no mood to provide details. "...Had some things I was thinking of and they distracted me," She quickly answered, then diverted attention before Twilight could ask any questions. "Anyway, what was it you needed help with? You didn't exactly tell me what you needed my help for." She asked, as she and Twilight walked into the castle.
"You'll see in a minute." Twilight said with a wink, leading Dash to the library. When they entered the library, Rainbow Dash saw that it was quite messy, and she could tell immediately what Twilight needed help with. She sighed. "This is going to be a long day."
"Oh, don't act like it's going to take so long, Rainbow Dash," Twilight giggled. "It'll probably only take us three hours exactly. It's not like you have anything important to do.. Right?" She asked, her tone of voice making it clear she was concerned that her friend had any sort of plans, that would be interrupted by library reshelving.
"No!" Rainbow quickly answered, perhaps a bit too quickly as Twilight seemed to become suspicious. Hastily, Rainbow added. "I mean, I do have some plans, some things I'd love to do at home. But I suppose they can wait while I help you put the books away." And he started to pick up a few books and place them on the appropriate shelves. "I don't see why you couldn't have asked Starlight for help instead of me." Dash thought, but didn't dare to say it outloud. Like it or not, she'd agreed to help Twilight, and she wasn't the Element of Loyalty for nothing.
Within exactly three hours, the two had finished. And without a second's hesitation, Rainbow left the castle. The day seemed to be almost over already, as the sun the was slowly going down in the distance. This didn't look too good for Dash, especially since she knew she still had to go to the store to buy more supplies. She decided to skip going to Starlight. If she helped one more pony, the shop she'd always gone to would likely close, and her plans for the evening would be ruined. She felt a little bad about not helping Starlight, or even seeing if she could help Scootaloo, but sometimes you gotta make a sacrifice. "Starlight's got Maud and plenty of other friends to help with kites, and Scootaloo… well I'll be sure to get her something to make up for not teaching her today." She thought, and zoomed across town as fast she could.
Soon Rainbow got close to her destination, a simple and discreet looking building known as "Foal Emporium", a store most ponies didn't even bat an eye at. It was too far out of town compared to the local foal store and Barnyard Bargains, both of which sold foal supplies for far less expensive prices. Only a hoofful of ponies knew what was really sold within the store's walls, and Rainbow Dash was one of them. Touching down lightly and glancing around to be sure the coast was clear, Rainbow decided to quickly put on her disguise. She didn't need anypony knowing she was buying diapers for herself. If somepony saw her, they would be sure to laugh at her, possibly even take a photo to publish in The Ponyville Express.
Dash quickly changed her mane a bit, styling it to look more like Pinkie Pie's. Then she pulled out a trench coat she had stuffed in her saddlebag (she'd picked it up on a quick stop to home after helping Twilight) and put it and a pair of sunglasses on. Content that she now looked completely different, she walked into the store, relieved that it hadn't closed yet. "Sure wish this place stayed open longer, it'd be more convenient to do this in the dead of night when nopony's around." She thought to herself, and made her way to the diaper aisle.
But as she strolled down the aisle, the cyan speedster noticed they were completely out of the diapers she'd gotten before. But they did have a new brand that interested her. "Enhanced diapers: Perfect for those who prefer more poof in their padding." Rainbow read, taking care to adjust her voice so nopony could recognize it. They were on sale, which was a big plus for Rainbow as she was a bit tight on money (who knew diapers could be so expensive) and she admit they looked cute, plus, maybe they would hold more than the ones she already had?
Rainbow didn't hesitate to scoop up a pack of the diapers, and then instantly made a mad dash for the checkout counter to pay for them. The less amount of time she had to spend in the store, the better.
Once Dash had paid for her new diapers, she dashed right on home! She was so excited, aside from work and helping Twilight with reshelving, she was happy at how things had turned out. Now she could just go home, relax, and act like a foal. But at the same time, she felt like she might of forgotten to help somepony. She couldn't put her hoof on who it was, but decided to not think about it, and once she was home she shut her blinds (but in her eagerness to indulge, she forgot to lock her front door). Her hooves trembling with excitement, Rainbow ripped open the package of diapers, unfolded the first one she could get her hooves on, and grabbed some foal powder and put it all over her area. Then she taped the diaper on, and she then put her mane in a ponytail, as she wanted to look more like a filly. Finally, her foalification was complete!
Rainbow took a moment to admire her diapering job, and how little she felt sitting in nothing but a poofy diaper. "Wow, these feel really comfy," She said to herself, no longer worried that somepony might hear her. "I wonder if they can hold a lot in them too?" She thought out loud, as she grabbed her stuffed Spitfire plushie and played with it. But while she was playing about, Dash had no idea that somepony was right outside, worried sick about her.
Fluttershy stood outside Rainbow Dash's cloud home, the door was open just a little, which made her think somepony might of broken into her friend's home, or worse! She decided to investigate, just to be sure her friend was okay. Once she pushed the door open all the way and had trotted inside, Fluttershy saw that everything seemed normal. Nothing was out of place. Her eyes scanned the living room and she saw her friend Rainbow Dash playing with a plushie, seemingly unaware that Fluttershy was nearby. But as Fluttershy was turning to leave, she noticed a diaper on her friend's rump. Needless to say, she was shocked about this and gasped (though not loudly enough for Dash to overhear). She quickly walked in, turned on a light, and asked with concern. "Rainbow Dash? Why are you wearing a diaper? What's going on?" For a moment she considered that Discord might be doing this as some kind of prank, but she didn't see him around or seen any traces of influence. But that just made her feel even more confused, she knew Dash didn't like diapers, so why was she wearing one?
Rainbow Dash gasped as the light flickered on and she heard the familiar voice of her childhood friend! "Horseapples, I must've forgotten to lock the door!" She realized, then out of shock she screamed. "FLUTTERSHY! Uh… I can explain! You see I was…. was…. just testing the diaper, yeah, that's it! I was testing it for... for… Surprise! She said she likes wearing them and… and.." But Dash stopped, she could tell Shy wasn't buying it for a second. "Ugh, fine, you caught me! I like to wear diapers sometimes, especially when I'm alone. The soft feeling makes me feel safe and small sometimes, plus they help me relax," She said truthfully, trying not to cry or look upset. "Uh… why are you here anyway?" She asked her friend.
"I just came by because you forgot to help me with my animals," Fluttershy explained, blushing slightly at how cute her friend looked. "I thought I should come and remind you, Dashie. But after seeing you in this, I can't help but find you cute in your new clothing," She cooed, then an idea struck her. "Hey, Dashie? How about I take you to my place and you can let me be your mommy?"
"Uh, I don't know, Fluttershy," Dash commented, nervously laughing. "I've never even thought about having somepony to do this with me."
"Well let's try it just this once, okay?" Fluttershy suggested. "It seems fair after I just caught you in this little predicament. After all, don't all little ones need a mommy to care for them and feed them and change their diapees?" She asked sweetly.
Rainbow put a hoof to her chin, as she pondered the offer. "Hmm.. ok," She said at last, and sighed."Guess I'll go," Then she immediately added in desperation. "But you have to promise me you won't tell ANYPONY! Especially not Scootaloo! If she found out I like this stuff, she might not even want to be my sister anymore! Do I have your word that you won't tell anypony?" She asked, the last thing she needed was her friends or fellow Wonderbolts finding out.
"I Pinkie Promise," Fluttershy nodded, and repeated the motions. "Cross my heart and hope to fly, stick a cupcake in my eye."
"Okay, just give me a second to get uh… 'changed'," Dash nervously replied, as she took off her diaper and reluctantly threw it into the trash despite it being unused. Putting the opened diaper pack back in the bag it had come in she added. "Ok, lemme just carry this to your place, Fluttershy. I'm sure your home will be a better place to let me be a baby anyway." And with that, the two flew off to the cottage. Dashie was actually quite interested in how Fluttershy would handle her role as a mother. She knew her friend was good with animals, and had taken care of the Cutie Mark Crusaders once, but she'd never actually seen her friend care for any kind of babies (except baby birds, but baby birds didn't wear diapers).
