As Rainbow Dash trotted into the changing area of the Wonderbolts locker room something dwelled in her mind. Something didn’t feel right. Why had she agreed to wear a diaper even after telling Spitfire she never had accidents? She wasn’t actually going to wear them, was she? She’d just said that to get Spitfire off her back. Yet now her mind was drifting to the infantile undergarments she’d been given.
The brash speedster stopped in her tracks before she could reach the designated changing area. “What am I doing with these diapers?” She pondered aloud. “I don’t really need them. It’s not like Soarin who wet himself mid-flight, he probably just drank too much and forgot to go to the bathroom,” Then she started thinking about Spitfire earlier. “And why was Spitfire acting so off? That bulge in her diaper looked suspicious, but there’s no way she actually did what I think she did, did she?”
Nopony was around to answer, so reluctantly Rainbow pushed them aside. It was stupid of her to dwell on this. If wearing them was the only way she could still be a Wonderbolt, then that’s what she’d have to put up with at least for now. Maybe once Spitfire saw she didn’t have accidents, she’d be diaper free.
Strangely, when the cyan coated mare opened the door to the changing room, she was surprised by the sight that greeted her eyes:
The room was now sort of like a mini nursery, it had cabinets fully stocked with foal changing supplies like powder and wet wipes, several packs of diapers, and a changing table with a strangely comfortable and inviting surface. The room smelled heavily of lavender and cornstarch, along with the occasional stench of ammonia or manure.
But most surprising of all was Thunderlane, the newest member of the Wonderbolts. It was clearly obvious from the bulge in his flight suit that he was wearing a diaper, but it didn’t look as big as Spitfire’s. That didn’t stop the stallion from nervously prancing in place as beads of sweat worked their way down his face. He seemed to be concentrating very hard on something.
“Thunderlane?” Rainbow called, catching the stallion’s attention.
Thunderlane almost eeped as he turned around to face Rainbow Dash without taking a step forward. “Hey, Rainbow Dash,” He greeted as he seemed to be almost dancing back and forth on his hooves. “Have you seen Spitfire anywhere lately?”
“I saw her in the locker room a few minutes ago, looking quite uncomfortable for some reason,” Rainbow commented. “Why do you ask?”
Thunderlane continued to trot in place as he seemed to be sweating harder. “I have to go to the bathroom really badly, but I can’t get out of my flight suit. For some reason I can’t get the zipper to unzip. I figured since Spitfire was the one suggesting we all wear diapers, she’ll know how to take them off.”
Almost on instinct Dash seemed to reply. “You could just use your diaper, you’re already in the changing room and it’s not like anypony will be around to see it.”
But Thunderlane shook his head. “No, I absolutely refuse! Now tell me where I can find Spitfire, I think I’m about to burst!”
“Maybe try her office.” Dash suggested.
Thunderlane bolted out of the room a second later, all the while shouting. “Thanks a lot, Rainbow Dash! You’re a lifesaver!”
“That was odd,” Rainbow thought to herself. “First Soarin wets himself, then Spitfire starts acting strange, and now Thunderlane can’t get his zipper off. And why did I tell Thunderlane to just go in his diaper, that’s gross! I would NEVER do that if I could help it, everypony would know!”
The cyan coated speedster couldn’t find a satisfying answer, so she turned her mind to other things. That changing table looked so comfortable for some reason. She didn’t technically have to use it, she could just put her diaper on here and now and then put her flight suit on over it. But something about the table fascinated her.
“It’s kind of nice, really soft,” The brash mare thought and pondered. “It kind of reminds me of the changing table I had as a foal. Whenever I was getting changed out of a diaper or having one put on, my parents always put me on the changing table. It always felt… comforting. No matter if I wet my diaper or messed it, my parents were there to care for me and clean me up. No worries, no fuss.”
She could even faintly recall a memory from long ago of her childhood nursery, laying on a changing table not unlike this one as her mom changed her dirty diaper. Windy was cheerfully whistling a tune while Rainbow played with her mom’s mane.
“It’s okay, Rainbow Dash, sweetie,” Windy cooed as she wiped her daughter down. “Everypony has accidents at some point. It’s perfectly natural. And that’s why you wear diapers.”
“Do even mommies and daddies wear diapers?” The toddler Rainbow asked (she was almost two years old and was slated to begin potty training in a couple of months).
Windy nodded. “Oh yes, when they were foals they certainly did. And everypony was a foal at some point or another. Some ponies even wear diapers to bed long after they stop needing them during the day.”
“Why is that, Mommy?” Rainbow inquired.
Windy just smiled and explained. “Because sometimes they have troubles with wetting the bed. But that’s okay, it’s a perfectly natural part of growing up. And regardless of whether you’re one of those ponies or not, Mommy will always be there for you. Even after she stops having to change your dirty diapers.” Then she nuzzled her daughter, who giggled in delight.
“You’re the best Mommy ever!” Rainbow happily exclaimed.
While dwelling on these memories, almost on instinct Rainbow climbed onto the changing table and lay down. She had already taken a diaper out of the package and was currently clutching it in her hooves, delighting in how soft it felt. Almost like having a miniature cloud in her grasp.
“I guess this isn’t so bad,” She thought to herself. “I wore diapers to bed after I was potty trained, even though I never once used them. Nopony but my parents knew then, and nopony’s going to know now except my fellow Wonderbolts. It’s better than having a mid-flight accident and embarrassing ourselves during a show or gala. I’ll just make sure to take them off afterward.”
Just then Soarin came in decked out in a flight suit and a diaper that poked through the opening in the back (he hadn’t yet zipped it up). When he saw Rainbow Dash laying on the changing table with her diaper in hoof, he gave her a puzzled look. He’d expected her to a lot more hesitant about this new policy, since she hadn’t suffered an accident like he had.
“Dash, you want me to help put you in your diaper?” He asked her and was surprised when she nodded back. “Well, okay. We Wonderbolts have to help each other from time to time. And since Spitfire’s currently unavailable, I guess it falls to me to do this for you. Now just hold still, okay?”
“Huh?” Rainbow responded, having zoned out for a moment. Yet strangely, she only offered minimum resistance when Soarin diapered her and then put her flight suit on, zipping up the hatch in the back.
Soarin smiled, giving Rainbow’s diapered rear a firm pat. “There we go, all nice and snug,” He giggled, before he then reached over and zipped up his flight suit. “So, whaddya think? Comfy, right?”
The cyan coated speedster frowned as she tried to shift her weight and felt the diaper force her legs apart. The added bulk was difficult to adjust to. “It’s kind of thick,” She complained. “I don’t see how I’m supposed to fly with something this heavy weighing me down.”
Soarin only giggled. “Trust me, it’s nowhere near as heavy as a wet flight suit. And far less of a hassle to change out of, I might add,” Then he encouraged. “It actually doesn’t slow you down that much once you’re used to it. In fact, before long it’ll be like it’s not even there and you’ll forget you’re wearing it. But if you don’t believe me, why not go out for a few test laps? Every bolt’s been doing since they got diapered.”
“I… guess I’ll do that.” Rainbow blushed as she waddled out of the changing room, still wondering why she’d felt the way she had earlier. Were the diapers a sense of nostalgia for her, or was something else involved?
Soarin only chuckled. “I can tell she’s gonna like ‘em. Pretty much every Wonderbolt already does. And I’m super jealous of her, Spitfire gave Rainbow Dash the best ones. The extra thick ones that you could wear all day with no bathroom breaks, and they still wouldn’t fall apart.” He thought to himself.
