Baby Makes Two

The two onesie-clad pegasi attacked the coloring book with abandon.

It was a Wonderbolts themed coloring book, though an older one if she had to take a guess as her friend was not yet featured in it. Many pages had already been filled, and what had stood out to Fluttershy was the quality of each page. Some pages truly looked like a foal had gone at it with one or two colors of crayon, paying no heed to the lines or color accuracy. Other pages, though, were colored in perfectly between the lines, colored to match the real-life ponies it depicted perfectly. Those ones weren’t bad even, as if Rainbow Dash was really trying.

She asked about it at the start while they were flipping to a fresh page, and Rainbow Dash blushed. “I like coloring,” she said, rubbing her foreleg. “But sometimes scribbling just feels, I dunno… right, I guess.”

Fluttershy hummed at the thought, then grabbed hold of a purple crayon and began coloring Fleetfoot’s mane. She started by keeping between the lines, but then stopped and looked at Rainbow’s progress. She was currently coloring her fellow Wonderbolt’s tail yellow, in stark contrast to the purple mane. She was scribbling excitedly, and so Fluttershy decided to follow suit. The lines were forgotten, and by the end they were barely noticeable in the miasma of waxy pastels.

“I do’n’ ‘ink ‘Fwee’foo’ wou’ appreshia’ dis” Fluttershy babbled around her pacifier with a giggle as they put on the finishing touches, namely a mustache that Rainbow was drawing on. Rainbow Dash giggled in response.

“I sheen worsh.”

The two continued to color page after page, suckling their pacifiers all the while. Occasionally, Fluttershy would let herself bounce on her rear, for no other reason than to feel her diaper squish under her again. Each time sent a wave of excitement through her, making the pegasus feel pride in her babyishness. Eventually though, the warmth of Fluttershy’s diaper faded, as did her enjoyment of the soggy garment. It began to feel clammy against her skin, and while the squish was still there it had lost some of its luster. Only now did she consider changing.

Only, she didn’t feel like she was done. She certainly felt as if she had more to give the swollen diaper. Something different. She was trying to be a baby after all, right? That’s certainly what babies do in their diapers, not just wettings. But for some reason, the thought still made her uncomfortable, like it was a step too far. A line that she shouldn’t cross.

But Rainbow Dash had alluded to that before, right? ‘Babies don’t care if they’re wet or messy’, she had said. What did that say about Rainbow Dash? It was hard to imagine the prideful pegasus doing that, but then again, so was everything else she had shown her tonight.

She pulled her pacifier out of her mouth. “Um, Rainbow Dash?”

“Hm?” her friend replied, still focused on her scribbling.

“How far do you like to go with, um…” She fidgeted with the crayon she was holding. “With your, uh, diapers.”

“Wa ‘oo you mea’?”

“Do you, um, do everything in them?”

Rainbow Dash spat out her pacifier. “You mean, do I poop in them?” Fluttershy blushed a bit at the blunt reply, and nodded. Only then did she notice Rainbow Dash was too. “Would… Would it be bad if I did?”

It was odd. This whole night, Rainbow Dash had somehow been exuding a sort of pride and confidence in her infantilism, which had come as a complete surprise and shock to Fluttershy. She would speak eagerly about her coloring books, her onesies, her bottles, and her diapers, going so far as to brag about her wet diapers. Amongst all that, it seemed weird that this would be the line for her.

But then again, wasn’t it the same for Fluttershy right now?

“N-no, not at all. I’m just curious.”

Rainbow Dash shifted uncomfortably, letting out an audible squelch from her diaper. “I do… sometimes.”

“Oh. Okay.”

The two sat in awkward silence for a moment, not looking each other in the eye. Rainbow was the first to break it. “Why do you ask?”

“I, um, sort of need to… do that.”

Rainbows ears perked up. “Oh? Well, okay! I’m cool with that if you are.”

“B-but that’s the thing. Do you…” Fluttershy twirled her hooves. “…like it?”

“Do I like it? Uh…” The blue pegasus picked up her crayon again and continued scribbling as she spoke, breaking eye contact again. “It depends. Usually, yeah.”

“Not always?”

“Nah. It’s almost always fun to do in the moment, but the cleanup usually sucks and so does the smell. Wetting is way easier.” She sighed. “It definitely makes you feel like a baby though.”

“Oh…” She rubbed her hoof awkwardly. “So… you don’t think I should?”

“Hay, no!” Rainbow replied instantly, perking up. “If you’ve never messed before it’s totally worth trying! Just, you know, you might or might not like it. It’s pretty gross.”

“Is that why me mentioning it is making you uncomfortable?”

“I’m not uncomfortable!” Rainbow stiffened as she replied, looking back up at Fluttershy. “I was just… worried that you would be, you know? I didn’t wanna gross you out. You seem pretty new to this, and I didn’t want to scare you off.” She sighed again. “I… never thought I’d get a playmate. I don’t want to lose that.”

Fluttershy lurched forward and pulled her friend into a tight hug, which caused Rainbow to yelp in surprise. “You don’t have to worry about that, Rainbow Dash. I never thought any of my friend’s would be like me either. I’m just so happy you are!” She squeezed tighter.

“Well… cool!” Rainbow Dash choked out, evidently struggling to breath. “You should probably let me go now so you can, uh, go!”

Fluttershy nodded and let go, blushing hard. “Oh, r-right.” She backed up from Rainbow and spread her legs slightly. “H-here I go!” Then, she closed her eyes, lifted her tail, and pushed.

Or rather, she tried to. Nothing happened for some time, and she nervously peaked an eye open to see Rainbow Dash staring at her expectedly. She flushed then, realizing her friend was watching her attempt to soil herself. “Um, R-Rainbow?”

“What’s up, Shy?”

“Can you, um, look away? W-while I do this?”

Rainbow Dash had the courtesy to blush at that moment, then stammered. “Oh, yeah, uh, right. I’ll just… color, some more.” Fluttershy watched as she shifted her position before the coloring book, putting her back to Fluttershy to give her some privacy. It would do.

Fluttershy decided to make another pass at it. Feeling like she needed something to comfort her, she placed her pacifier in her mouth and scooped up her teddy bear into her right foreleg. This time, she let her hind legs squat, giving her a more comfortable position for the act. She pushed again, and again, and again.

On the fourth time, she felt something move within her, pushing itself out slowly and steadily. Fluttershy’s heart raced, and she felt a tingle through her spine as she committed to her taboo and infantile act. She pushed again, and the weight finally settled into the rear of her diaper. Then she pushed again, then again. She continued until she was empty.

In the end, she could feel her diaper sag beneath her under the new load. She shuffled on her hooves, feeling the diaper jiggle between her thighs at the motion. It was an odd sensation. It wasn’t comfortable, though it wasn’t entirely miserable. Then the smell hit her. Her work with animals had made her accustomed to such scents, but she wasn’t used to it coming off of herself. It was a lot to take in.

But she had done it, she realized. She had fully used her diapers. Here she was, clad in a onesie, holding her teddy bear, suckling her pacifier, and wearing a wet and poopy diaper. There was no denying it now; she had crossed the threshold of adult babyhood. And despite her contrasting feelings of her diaper’s current state, she felt complete.

She practically squealed behind her pacifier and trotted in place in excitement. This made her mess jiggle around even more, drawing her back to the present. Taking another breath, she waddled back to her friend, attempting to not spread it around too much.

Rainbow Dash sniffed as she approached, and she looked up from her coloring with a smirk. “Smell’s like somepony made a poopy!”

Fluttershy blushed furiously, but couldn’t help but giggle at her friend’s cutesy tone. “I may’ a poopy!”

Rainbow Dash smiled and waived a hoof exaggeratedly in front of her nose. “No kidding. So, how was your first one?”

Fluttershy dropped her pacifier. “It was, um… it was fun. I think I want to change though.”

“Yeah, I get feel you. Sometimes it’s only fun for a few seconds. I know you have some of your own, but I’ve got some more Cloudies in my bag if you want to try those. And some wipes.”

That’s when Fluttershy got an idea; one that made her blush harder than she had all day. She bounced on her hooves nervously, looking at the bag Rainbow Dash had mentioned.

“You okay, Shy?”

“F-Fine,” she replied at a mouse’s volume. She hid behind her hair as if in instinct. “I-it’s nothing.”

“No way, something’s totally bothering you.” At that, Rainbow Dash got up and approached Fluttershy, looking at her sympathetically. “What is it?”

“I-I just, um… What if you, um….”

“Yeah?”

“What if you…. changed me?” Rainbow Dash’s eyes widened, and a wave of panic rushed through Fluttershy in an instant. “I-I’m sorry, that was too far, forget I said anything!”

“Ch-change…. Uh….” Rainbow Dash shuffled form hoof to hoof, clearly uncomfortable.

“I-I’m sorry!” Fluttershy’s heart raced, and she could feel a sweat start to build. She shouldn’t have mentioned that. She shouldn’t have even thought that. It was disgusting. It was too much to ask anyone. How would Rainbow Dash ever even look at her the same again?

Apparently, pretty easily, as she felt two blue hooves grab each side of her face and pull her towards their owner’s. “Hey, snap out of it, ‘Shy! I’m just surprised. You’re cool!”

“B-but I –“ she was cut off as her pacifier was shoved into her mouth. She immediately started suckling, desperate for comfort.

“I’m not mad! I just… never thought about changing someone else before. It’s a little weird.” Rainbow clammed up immediately. “Not weird! I mean, uh, different!” she sighed, looking down for a moment. When she brought her eyes back up to meet Fluttershy’s she said “Do you, you know, want me to?”

Fluttershy looked away, but nodded her head.

“A-alright. That’s cool. I mean, it can’t be grosser than changing myself, right?”

Fluttershy looked back in surprise. Her eyes practically sparkled. “Weally?”

“Uh, huh!” Rainbow nodded, looking as if she was more trying to convince herself. Nevertheless, she pulled on Fluttershy’s hoof, guiding her to the corner of the room with the bag of Rainbow’s supplies. “C’mon, lets get the baby out of that stinky diapee!”

Fluttershy’s heart raced as she followed her friend. She scooped up her teddy bear along the way, clutching it to her chest. At Rainbow’s request, she laid down on the floor on her back, making an effort not to squish her mess against her any more than she had. Rainbow Dash in turn sat down between the butter pegasus’s hind legs. She hugged her teddy bear tight, and suckled her pacifier anxiously.

Meanwhile, Rainbow Dash retrieved a new diaper from her pack. Unlike her plain white diaper she was currently wearing, this one had adorable cartoon clouds printed on the landing strip, each with a smiley face on them. Light blue clouds peppered the remaining plastic. It positively radiated foolishness, and Fluttershy’s eyes glimmered at the sight. Rainbow pulled out a bottle of baby powder along with a packet of wipes. She then unfolded the diaper, making sure to shake it around as she did so, fluffing it like a pillow. Fluttershy never considered doing that herself.

“Okay, then, let’s see how bad the damage is.” Rainbow Dash unfastened the buttons around Fluttershy’s crotch and pulled back the flap of the onesie, exposing the well-used diaper beneath. As expected, it had swollen considerably and the white shell had turned a subtle yellowish tint. A noticeable bulge stuck out near the bottom, providing evidence of Fluttershy’s latest infantile deed. Her blush deepened, feeling herself become more and more exposed before her best friend. “Heh, you really went all out, ‘Shy!”

Fluttershy squirmed a little at the tease and her heart beat faster. She tried to relax and let her head back, closing her eyes and thinking of just her pacifier. Meanwhile, Rainbow Dash slowly ripped the diaper’s tapes open one by one. Fluttershy hugged her teddy bear tighter as the soiled diaper was peeled away, putting herself in full view of her friend.

To Rainbow Dash’s credit, the pitiful whine the boisterous pegasus let out as she beheld the gross task ahead of her was brief. Despite that, she quickly got to work. At her instruction, Fluttershy lifted her rear up enough for Rainbow to remove the soiled diaper. Then, in a bit of a rush, she wiped Fluttershy clean. Fluttershy kept her eyes closed and head back. She was only mildly aware of the gagging noises her friend made as she performed her task. She then felt a prod on her backside, signaling her to lift her backside up again. She complied, and when she settled down again, she was resting on a fresh, fluffy diaper.

“Almost done,” Rainbow said more to herself than to Fluttershy. Fluttershy felt a sprinkling of baby powder land on her, and then heard the crinkle as Rainbow Dash brought the front of the diaper up and over her waist. Then one at a time, the blue pegasus pulled the tapes in, securing her into the fresh garment. “Aaand… done!” She announced as the last tape was applied. “A nice, clean diaper for the big baby! Now we just gotta snap this up…”

Fluttershy opened her eyes, smiling behind her pacifier as she felt Rainbow fasten the snaps on her onesie again. Once that was completed, she sat up and looked at her friend. Rainbow wore a smile, albeit one that was a little strained. “So, how’d I do?”

She let out a yelp as Fluttershy leapt forward, hugging Rainbow Dash tight. “Ih’ wah ama’ing!” she babbled. “T’ank ‘ou sho ‘ush!”

“Uh, no problem! What are friends for, heh heh.” She awkwardly patted Fluttershy on the back. “That may take some getting used to though.”

Fluttershy giggled. “I ‘an shansh ‘ou ‘nesht if ‘ou wan’”.

“Sorry, what?”

Fluttershy let her pacifier drop, catching on the lanyard. “I said I can change you next, if you want. That seems only fair.”

“Heh, naw, I think I can wait. But I’ll take you up on that in the morning. I’ll need to give you something to match!” Both oversized babies laughed at that, then settled into the hug again. They stayed like that for a moment until Rainbow Dash let out a mighty yawn.

“Tired?” Fluttershy asked.

“Kinda, yeah.”

“Well, it is getting late. It’s bedtime for us babies!” She giggled. “Come on, you can sleep with me tonight.”

Rainbow nodded, and Fluttershy took her friend’s hoof, leading her up the stairs into her bedroom. Rainbow followed dutifully, eyes half open. They reached her bed, and Fluttershy quickly directed her friend under the covers. Rainbow smiled as she was given her pacifier again. She was tucked in, then Fluttershy fluttered to the other side and slipped under the covers herself. As soon as she was nestled under the covers, she felt Rainbow cuddle into her, holding her tight. She relaxed, and turned to return the embrace.

“Thank you so much, Rainbow Dash,” she mumbled, feeling tired herself. “I had so much fun tonight.”

“Mhmm,” Rainbow Dash mumbled. “Gotta do dish… agai’… shometi’…”

“Uh, huh. But, um, you really should knock, next time.”

Rainbow Dash didn’t respond, her breathing falling into a steady rhythm. With a smile, Fluttershy put in her pacifier, cuddled further into her playmate, and let herself drift off into a blissful sleep.

She slept like a baby, and she wouldn’t have wanted it any other way.
