Baby Makes Two

Fluttershy had no plans tonight.

She had already finished her chores around the cottage. All her animals had been attended to, Angel had been given a bowl of lettuce and carrot slices, and overall, everything that had to be taken care of had already been taken care of. As a result, Fluttershy had an evening to herself, which was a common but always welcome occurrence.

She was already dressed for the occasion.

Fluttershy gently glided down the stairs from her bedroom to her living room, a fuzzy teddy bear firmly clutched to her chest. A chorus of crinkles echoed throughout the walls of the cottage, emanating from the large white diaper she had taped around her waist. A light blue pacifier, the same color as her eyes, covered her lips. She gave it a suckle as her hooves touched the floor, and she pranced over to her couch.

Fluttershy had spent a few nights like this recently. She had always been curious, idly fantasizing about what it would be like to be young again; to especially be a baby again. But she never pursued it out of fear of being caught. It was too taboo; what would ponies think of her? What would her friends think of her? Or her family? It was a side of her she had kept locked up for years, too afraid to let it out.

Only recently, within the last month, had she finally worked up the nerve to go for it and live out her dream. She had put in a mail order for some adult diapers and an adult pacifier, which promised discreet shipping and had delivered on that promise. She wanted more, but just getting that much was hard for her, and more only meant she would have more things to hide when her friends were over. She figured diapers and a binky would be more than enough to make her feel like the baby she wanted to be.

And it was, though even then she was still nervous to let herself “baby out” as it were. She’d only gone through a handful of diapers in her pack, afraid to let them run out too quickly. She opted to save them for special occasions. They were very comfortable, and the crinkly sound the made when she walked did wonders to sell that distinctly infantile feeling to her. The taboo of it, however, made it difficult for her to get into the headspace she wanted, as if fearing that somepony would walk in on her at any moment. It felt wrong, but she still wanted it…

She shook her head to rid herself of those thoughts. She wanted to feel little tonight, to not have to worry about anything. She plopped down onto the floor of her living room, just in front of the couch, and squeezed her teddy bear to her chest. She gave her pacifier a suckle, and let out a sigh. It’s okay to be little tonight, she assured herself. Nopony is going to find out.

That was the precise moment when Rainbow Dash let herself in the front door. “Hey, Fluttershy! You left the front door unlocked again. Are you… free… to… uh…”

Fluttershy froze, pupils shrinking to pinpricks as the voice reached her ears. In an instant, she swiveled around from her spot on the floor, instinctively holding the teddy bear in her lap in a vain attempt to cover up her diaper. Rainbow Dash stood in the open doorway, seemingly frozen in place and staring in shock at her. The blue pegasus’s mouth flapped noiselessly, as if trying to form words but unable to get them out.

“W-Wainbow Da’!” The butter pegasus cried out. With horror, she realized her pacifier was still in her mouth. In an instant she reached up, plucked it from her lips, and fruitlessly hid it behind her back, trying her hardest to suppress a wince. “W-what are you doing h-here?”

Rainbow Dash continued to stare, slack-jawed.

“I-I can explain!” Fluttershy pleaded. “It’s not… I mean, it is, but… I mean…”

“Fluttershy, you’re a… you…” Rainbow Dash trailed off, raising a hoof towards her friend with eyes continuously growing to saucers.

“I… I’m not… I’m sorry, I….” Fluttershy clenched her eyes shut and trembled, awaiting the words from her friend that would seal her fate. Laughter, maybe disgust, something.

“Ohmygoshohmygoshohmygosh!” Rainbow blurted out at last. Confused, Fluttershy opened up an eye to see Rainbow Dash looking positively ecstatic. She had hopped into the air, clutching her hooves to her chest. A bright and toothy smile was beaming on her face, and in an instant the mare was upon Fluttershy, engulfing her in a strangling hug. Fluttershy fell limp in her grasp, too stunned to reciprocate. Rainbow didn’t notice. Her diaper crinkled loudly from the contact, and she felt a distinct longing for the teddy bear that she had accidently lost hold of in the sudden hug.

“R-Rainbow?” She found herself saying. “W-what….”

“This is so cool!” the colorful mare cheered. “I never thought that you… or any of my friends… that they would…. Eeeee!” she squealed, buzzing her wings like a hummingbird. She let go, and suddenly Fluttershy felt her diaper exposed for her friend to see again. She quickly shuffled over to her fallen teddy, cuddling him close again and staring at the blue pegasus in a wary mix of fear and confusion. She shuffled, again hearing the crinkles that should have been damning her to mocking yet for some reason… weren’t.

“Um, R-rainbow Dash?”

“Fluttershy! Are you doing anything tonight?”

“Um, well, no, but-“

“I’ll be right back! Don’t go anywhere!” The mare zipped out of the house, leaving a rainbow trail behind her. Before Fluttershy could even register her departure, Rainbow zipped back in. “And don’t change either! I promise you’ll like this!” Before Fluttershy could question her, she was gone again.

Unsure of how to respond to what had just happened, Fluttershy simply whimpered. She retrieved her pacifier and reinserted it into her mouth, giving it a few calming suckles. She held her teddy bear ever closer, feeling her emotions wage war inside her. Rainbow didn’t laugh, she thought, trying to console herself. In fact, she looked… excited?

Her instincts told her that was a bad sign. Rainbow Dash would certainly tell somepony. That was exactly what she was doing now, no doubt about it. Soon all of her friends would know Fluttershy was a freak who liked to put on diapers and act like a baby. There was no way she would be able to show her face again. She felt her eyes start to glisten. What was she thinking? Why would she think this was something acceptable? She buried her face into her stuffy, holding it in a vice grip and suckled her pacifier ever more intently.

She stayed there for a few more minutes, feeling herself spiral deeper and deeper into despair. Worst case scenarios filled her head. She thought she should change out of the diaper and put away her toys, but what was the point. Rainbow Dash had already seen it, and soon everypony else would know about it for certain. Everypony would know just how much of a freak she…

“I’m back!” Rainbow Dash announced, cheerfully flittering back into the abode. “This is going to be so awesome! You’ll love…. This?” Rainbow trailed off. Fluttershy could feel her eyes on her, but couldn’t find it in herself to peal her face out of the fluffy head of her teddy. “Hey, Fluttershy, you good?”

Fluttershy simply whimpered in reply.

A moment went by in silence, Fluttershy’s cries being the only sound. The butter pegasus felt a weight touch down next to her, and suddenly a feathery wing was draped over her.

“Hey, Shy, I’m not going to tell anypony about this, you know.”

That was enough for Fluttershy to break away from her stuffy and look over at her friend. “B-buh… buh I…”

“Hey, no buts! I wouldn’t do that to you. In fact, I got something to show you. I promise you you’ll like it.” With a final squeeze of her wing, the mare took off down her hallway. Only then did Fluttershy realize that Rainbow Dash had a blue and yellow duffle bag with her, likely her Wonderbolts bag. She carried it off and down the hall, and the pegasus could hear the sound of her bathroom door open and close.

Fluttershy waited at her spot on the floor, still holding her teddy bear tight. The fear had abated somewhat, though it wasn’t all gone. Instead it was replaced by a sort of morbid curiosity. She didn’t have much time to dwell on that though before the bathroom door opened again, and Rainbow Dash emerged. She rounded the entryway and hovered before Fluttershy, holding her hooves out to the sides in a showpony manner that belied the blushing, nervous look on her face.

“Tada!”

Fluttershy’s breath hitched as she took in the sight of her friend. The blue pegasus was dressed in navy blue and yellow outfit that matched her duffle bag. It had the same pattern and logos as a Wonderbolt flight suit, but that was where the similarities ended. It resembled more of a T-shirt, though with a much larger collar that seemed to stretch to her shoulders. The bottom stretched down the whole length of her torso and came together at the crotch, a series of three buttons holding the flaps together and keeping her hind legs exposed.

Rainbow Dash was wearing a onesie.

But it was more than that. Fluttershy’s eyes caught on to the white plastic that was sticking out the legs of her onesie, and the slight bulge that surrounded Rainbow’s waste. She was wearing a diaper. Finally, Fluttershy noticed the magenta pacifier that was sitting in her friend’s mouth, and the blue strap clipping it securely to her onesie’s collar.

Fluttershy’s pacifier fell from her mouth as her jaw went slack.

“R-Rainbow Dash… you…. You’re….”

Rainbow Dash’s smile faltered a bit and she blushed heavier. Her hooves clopped down on the floor as she landed and sat on her haunches, her diaper making an audible crinkle as she did so. She sheepishly rubbed a hoof on the back of her head, and let her pacifier dangle from her lanyard.

“Y-yeah, I’m… you know… also a, uh…” she gestured to herself.

“An adult foal?”

“Yeah, that.” She shuffled, clearly embarrassed. “I’ve just been kinda, you know, keeping it to myself. Never planned on letting anypony ever figure this out, but…” She smiled, holding out her hooves to Fluttershy as if presenting her. “But clearly I don’t have to worry about that with you… right?”

Fluttershy continued to stare in amazement for a moment. Her jaw closed, and a bright smile appeared instead. In a moment, Fluttershy closed the distance on Rainbow Dash, wrapping her in her hooves. She squealed in excitement. Rainbow Dash returned it with a sigh. After a moment, the blue pegasus broke away.

“So, if you don’t have anything going on tonight, do you wanna have a… you know… a play date?”

“A… play date?” The idea was so infantile, so childish. She hadn’t had a playdate since she was a little filly. The idea of playing baby with one of her best friends was a dream come true. “I wouldn’t want anything else!” Fluttershy returned, radiating joy. She wilted slightly as she looked over to her meager pile of toys on her rug. “I don’t have much though.”

“That’s fine! I brought some extra diapers and stuff. I’ve even got an extra onesie that I think might fit you, if you’d like.”

Fluttershy felt a tingle in her stomach at that. She didn’t have any baby clothes besides her diapers. It had been on her wish list, but she never knew the right way to go about acquiring them, nor did she have the nerve to find out. “Can I?” she eagerly asked.

“Yeah, totally!” Rainbow Dash quickly wandered over to her bag, a distinct waddle gracing her gait. Fluttershy couldn’t help but giggle at the sight. The blue pegasus soon pulled out a white onesie, this one with paw prints on it in various pastel colors. Fluttershy’s eyes twinkled as she beheld it, and she let out a squeal of delight as she hungrily reached for it.

Only, Rainbow Dash ended up holding it away from her with a sly smile. “Woah there, Shy! Babies can’t dress themselves, right?”

Fluttershy cocked her eyebrow for a moment until it clicked with her. “O-oh, right!” With a cute giggle, she plopped down in front of her friend on her rump and held her hooves up to the ceiling. Rainbow Dash laughed in turn, then draped the onesie over the butter-yellow pegasus head and pulled her hooves through the sleeves. She then gestured for her friend to stand up. Fluttershy obliged, and soon found Rainbow Dash circling to her rear. She blushed as she felt her friend buttoning up the snaps around her plush diaper.

“Aaand there ya go!” Rainbow eagerly announced as she finished with the last snap. With a smile brighter than the sun, Fluttershy quickly waddled over to a nearby mirror to take a look at herself. The onesie fit almost perfectly, perhaps being only slightly on the snug side. Nevertheless, she could feel it hugging her diaper to her rear tightly, and as she looked into the mirror her jaw dropped. The way the white garment bulged around her waist, and the way her onesie snapped in the rear leaving her legs bare, was positively infantile. Just as she had seen on Rainbow Dash, her diaper peaked out ever so slightly from her legs, adding magnitudes to the foalish look. She felt herself mouth a quiet “wow” as she stared at herself.

“Hey, Shy, I think you’re missing something.” She turned at Rainbow Dash’s voice, only to be greeted by the mare placing her pacifier into her agape lips. Fluttershy gave it a suckle in surprise, then another, then noticed the other thing Rainbow had in her hooves. With a smile, Rainbow held out her teddy bear, and Fluttershy accepted it. When she next looked into the mirror, all semblance of adulthood had fled like a bat in the light. Standing in the mirror was an oversized baby, clad in a onesie, sucking on a pacifier, and clutching her teddy bear. Fluttershy took it in for a moment, then clenched her eyes shut and let out a delighted squeal. She danced on her hooves, her wings sprouted outwards in excitement.

Fluttershy was a baby again, just as she had dreamed of.

“I guess that means you like it, then. You look adora- woah!” In an instant Fluttershy was on Rainbow Dash, embracing her in a bone crushing hug. “Gah! Fluttershy!”

“Ish’ perfec’!” Fluttershy replied through her pacifier, continuing to hold tight. “Than’ you sho mush!” Rainbow Dash hesitantly patted her friend’s back, then pushed against her should in an attempt to pry her off a little.

“No problem, Shy. You, uh… you make a cute baby.”

“You ‘oo!” To Rainbow’s relief, Fluttershy then pulled away, but no before picking up Rainbow’s pacifier and placing it in the mare’s mouth with a cute giggle. She then picked her plush teddy bear back up, then eagerly head it out in front of her towards Rainbow. “Weh’s Pway!”

And so, with an eager nod from Rainbow Dash, the oversized foals played.
