It is a beautiful day in Ponyville today. Princess Celestia’s sun shines brightly over all of Equestria and Ponyville. The weather is warm out but not particularly hot. A bunch of ponies are already out and going about their day. Businesses are booming with business. Young fillies and colts are running around laughing and playing as their parents look on. Other ponies are shopping or talking to other ponies. Some ponies are enjoying a delicious meal either by themselves or with somepony. The day was so beautiful that there was barely even a cloud in the sky. 


        There is a particular cyan Pegasus mare that can be a little lazy at times despite how she athletic she is. This so happens to be Rainbow Dash, a Wonderbolt and the Element of Loyalty of the Mane 6. It is sometime after noon and she is still sleeping soundly on her bed in her cloud mansion making loud snoring sounds. She is wearing a purple robe with some green slippers on. Eventually she woke up with a groggy feeling. Rainbow Dash slowly adjusting her eyes Celestia’s bright sun. She rolled over to see what time it was. Her eyes widened and completely panics when she saw the time. 




Rainbow Dash is a part of the Wonderbolts afterall and today Captain Spitfire of the Wonderbolts had called all of the Wonderbolts for a special and very meeting today about the future of the Wonderbolts moving forward. The meeting was scheduled for 1:30PM and it was already 1:07PM. Rainbow Dash throws her robe and slippers off and quickly squrims off of bed. She flies- well more like… Zooms to her kitchen and pours an entire box of cereal down her throat. With a loud gulp, she quickly flies out of her cloud mansion and flies directly to the Wonderbolts Academy. As she gets there, no pony is seen anywhere, no pegasus is in the air flying or anything either. Rainbow checked various places for the rest of the Wonderbolts crew including trying to look for Captain Spitfire in her office but to no avail as she wasn’t there. There is still one place that Rainbow Dash hasn’t checked yet and that is the locker rooms. As she reaches closer she finally hears voices and sighs of relief to have finally found everypony. Though for some reason she also heard various groaning noises, sounds of disgust and more. 


        As Rainbow Dash walks into the locker room, she freezes, her jaw drops and she is so much shock by what she is seeing before her very eyes. Dash is clearly very taken aback by what she is seeing. She sees Spitfire laying on the ground, sitting ontop of a diaper and getting baby powder powdered onto her by Angel Wings. She looks around the room and sees Thunderlane touching Fleetfoots rear end as Fleetfoot has a look of caution and embarrassment. Rainbow Dash can see the outlines of their poofy diapers inside their Wonderbolt uniform. Rainbow Dash gets a whiff of the scent of urine and looks to see a trash can full of used diapers sitting in the corner. Dash quickly stuffs a hoof into her hoof to prevent herself from throwing up. 

        
As she turns her head to face towards Spitfire again, she gets startled as Spitfire is standing right in front of her with her fresh diaper on. It is clear that Spitfire doesn’t look too happy with Rainbow Dash. She yells at Dash with a very loud voice that it even startles some of the other Wonderbolts.

        “What happened to you, Rainbow Crash? Why are you late today? I told every single Wonderbolt that we had a very important meeting about the future of the Wonderbolts about a new rule we have have added and you just decide to show up late and miss it?! On your hooves, explain yourself! Spitfire yelled in frustration. Rainbow stands in formation.
        “Yes! Captain Spitfire, ma’am! I apologize for being late. I accidentally slept in and I will it will never happen again! But could you please tell me what the buck is going on?! What is with the diapers?! It is disgusting, no offense… Rainbow Dash said with a gulp. 


        “You better not sleep in again! You know if you were here on time then you would know! Well since you are finally here I will explain to you. I explained to you before that the Wonderbolts are very competitive and we waste no time making sure we flying correctly and practicing and pushes ourselves so far to the point where we feel like our wings are going to fall off! I have made a discovery that we our wasting our time and losing time we could be using for practice when we all stop to use the bathroom! Well this will end today as the new Wonderbolt rule is a dress code rule which in order to be apart of the Wonderbolts, you will wear and use diapers! It is more efficient if we want to save time!” Spitfire yelled in a stern tone.


        “B-but w-what?! That is so gross and weird! I am sorry captain, but I refuse to smell like a trashcan with my pee and you-know-what else against me as I fly around doing tricks in the air! This is so not cool or awesome!” Rainbow shouts back.


        “Okay, Rainbow Crash. Well it is either put on your damn diapers or leave the Wonderbolts Go lay down on the changing mat or walk out of the door and leave. I will keep it that simple.” Spitfire says in frustration, shaking her head.

        
Rainbow Dash had to give it some thought which lead into deeper thoughts. This was her dream, she couldn’t leave the Wonderbolts because of some silly diapers. She gave in and laid down on the changing mat. Spitfire ordered the rest of the team to leave the locker rooms and to meet them outside. It was a very embarrassing, quiet and intense between Spitfire and Dash as Spitfire diapered her. Dash had to cover her eyes to avoid looking Spitfire in her eyes. After she was diapered, she put on her uniform but it was on a little more tighter than usual because of the diaper. 


        The diaper had spread her legs apart to the point of her having to waddle behind Spitfire towards outside. After several hours of intense Wonderbolt training, Spitfire gave them a small water break. Dash felt that familiar sensation in her bladder and bowels that she had to go to the bathroom. Unfortunately for her, it wasn’t just going pee either. She also had to poop. She nervously walks up to Spitfire and to ask;


        “Captain Spitfire ma’am? I would like permission to use the bathroom.” Rainbow says a bit worried and shyly.

        “Toilets are off limits are being removed as we speak. Use your diaper and you can get changed at the end of the day.” Spitfire says with a stern and commanding tone.

Rainbow Dash couldn’t believe her ears. Spitfire was actually serious about this whole diaper thing. The pain was increasing more intensely in her bladder and bowels. Rainbow Dash actually shed a tear when she gave up and lifted up her tail. Dash’s face became as red as a apple as she messed and wet herself. After a while she stood up with a look of digust. She then gets startled as a flash appears and she sees Soarin taking a picture of her in a freshly used diaper. This was going to take a long time to get used to…
