Applejack x Rarity Inflation

Applejack looked at her partner with a puzzled look in her eyes. “Yer kidding me…right?”

Rarity covered her face as her cheeks turned a slight red. “Yes, Applejack, really.”

It had only been a couple months since the two mares had started dating. Already having delved into the more private attributes of being in a relationship, the both of them agreed that it was time that they became more ‘open’ about their interests.
With a feint, “huh,” Applejack trotted over to the helium tank that Rarity had pulled out from the depths of her closet. She looked it over, intrigued enough to pick up the rubber hose that was attached to the metal valve on top. “So, where does this go, exactly?”

“I think you know exactly where that goes.”

“And then ya just… turn it on?”

“Yes, nothing more to it.”

Applejack stared at the tank without a word, scratching her head as she did so. “Listen, I know we agreed on not laughin’ or being judgmental or whatever, but this… this is more confusin’ then anything.”

Rarity lowered her ears and started to kick sheepishly at the ground. “For the record, I am aware of how strange this may seem-”

“May?” Applejack interrupted her with a raised eyebrow.

Rarity scrunched her face with a brief huff. “Alright, fine. I am aware of how strange this is, but honestly, Applejack you should have known to expect t something, well, out there. I did tell you that it would be rather peculiar.”

Applejack rolled her eyes. “Ah was expecting somethin’ like straps or gouges, maybe even a paddle. But never would ah have expected…” she drifted off and looked back at the tank with a hesitant glance, “that.”

Rarity began to rub at her temples. “You really are overacting, Applejack. Yes it’s weird and I admit that.  But nopony is ever truly normal. Besides, are you really willing to criticize my interest after what you showed me last night?”
Applejack’s entire face went beat red. “Y-you don’t got nothin’ on that. This is way weirder than anything’ ah could ever cook up.”

Rarity held up a hoof to her mouth and giggled. “Perhaps, but it does pay to remember not to throw stones while living in a glass house.”

Applejack paused and tapped at her chin. “Well anyway, how do ya usually go about, uh, usin’ it?”

A bright flash appeared in Rarity’s eyes and they widened with excitement. “Oh, if you’d really like to know then I’d be more than happy to give you a demonstration.” Rushing up to the confused mare she snatched the hose out of her hoof. “It’s very easy once you know what you’re doing.” Backing herself away from Applejack, Rarity dragged the rubber tube, making sure as to give herself plenty of room to expand.  Positioning her hind hooves further apart, she spread legs. Rarity’s eyes had become focused on the tube, the rising in her chest becoming more vigorous. Applejack’s gaze became intently fixed, like an observer at a freak show. Rarity then carefully inserted the hose from behind and into her gaping hole, every part her convulsing as it entered. “N-now, if you would be so kind. Would you mind turning the valve for me?”

Applejack did as she was asked to, turning the valve slightly to the right. An immediate hissing sound was heard as she did so, followed by the soft coos of an inflating pony. The air pressure was low, but sure enough Rarity’s belly was expanding. It started as a slight lump and continued to grow casually.  She pushed her hooves into the swelling mass, her whole body shivering. With only a few minutes of air time, it already looked as though she had just returned from the local buffet. “Ok, ok, that’s enough for now,” she said through wispy pants.

Applejack again obeyed and turned the valve in the opposite direction. With the hissing sound now ceased all that could be heard was Rarity’s heavy breathing. She looked up from her bloated belly and smiled. “Well, what do you think?”
The dazed pony remained silent. An awkward moment of stillness passed before she finally answered. “Well…it’s certainly different.” Applejack scratched behind her ears with a thoughtful look to her face. “What I actually want ta’ know is how’d ya even find out bout’ this?”

Rarity held up a hoof to stifle another giggle. “Oh, well, Pinkie was showing me a trick she had started doing for her parties and I just took some creative liberties with it.”
“Well,” Applejack paused. “It’s certainly different.”

Rarity shook her head, aware that this wasn’t going anywhere fast.  “Yes, yes, I think we both can agree that this is different.” She tapped her head, trying to figure out a way she could convince her partner to give it a try. Just once and that’s all it would take for her to understand. “But you know, Applejack,” she continued. “It certainly doesn’t hurt to delve into something different every now and then. Just think, we would never have gotten together without our willingness to try something new, despite our predispositions.”

Applejack timidly scratched the heel of one of her front hooves, altering her gaze away from Rarity. “Ya, but, being with somepony ya care about is different from recklessly shoving some rubber in yer…yer cooch.”
Rarity couldn’t help but blush. One of the hardest parts of their relationship was getting Applejack to become more open about her feelings. With a small smile she went on. “Yes, I won’t deny the truth to that. But being with another pony also means occasionally stepping out of line to make them happy. This is a two way partnership and I already stepped off the fixed path last night when you-“

“Ok, ok, ah got it.” Applejack looked to the air tank, her ears lowering at the thought of becoming a balloon. “Ah’ll indulge a bit in yer strange fantasies.”
Rarity’s smile turned into a wide grin which caused her entire face to gleam. “Oh, how happy I am to hear that. And look.” Her horn turned sky blue as the dresser behind her became shrouded in an aura of the same color. One of its drawers opened and another rubber hose flew out, landing between the two ponies. “I already got a hose just for you.”
Applejack looked at the hose reluctantly, kicking at it gently. She forced a shaky grin onto her face. “Heh, that’s mah Rarity, always prepared fer anythin’”

Rarity felt a fluttering in her chest and she knew it wasn’t from prodding her extended midsection as they talked. “Yes, well, I figured you would be more open to the idea if you had another pony to do it with.”
Applejack looked into the light blue eyes of her partner and felt a more genuine smile spread across her face. “Thanks, ah appreciate it.”

The hose once again took flight and seemingly attached its self into the conveniently present second air valve. The other end was then lifted towards Applejack where it landed in her outstretched hoof. She looked at it with only a sigh. Her face had already turned completely red by the time she spread her legs apart. With the dexterity of a seamstress she slipped the rubber in, like a needle through a thread.

“Are ya sure this is safe?”

“As long as you don’t overdo it.”

“Well… then ah think ah’m ready.”

Rarity chuckled to herself. The blue coloring returned over her horn and soon spread to the air valve. Slowly it turned on.

Both ponies began to expand, each one having a very different reaction from the other. Rarity simply closed her eyes and took in a deep breath. She rubbed her expanding stomach as it swelled out from under hooves, gasping with each poke and prod that made contact with her delicate tummy.

Opposite of her, Applejack watched with an odd combination of worry and amazement. Feeling the air flow through her was oddly refreshing, the cool substance making its way through her sensitive walls. The endless gas built up inside her gut and pushed it out just as it did to the more experienced mare in front of her.

She felt it swirl around her insides which reminded her of the feeling you get from drinking too much soda. She thought of the carbonation fizzing up from within until it had to be released in a one big belch. Only Applejack didn’t feel the need to burp, nor was there any way to release the inner pressure.

The both of them continued to expand at about the same rate. Thanks to her head start though, Rarity was always at a slight advantage in terms of size. With various squeaks and squelches her white belly grew, resembling a snow ball that had been rolled up along the ground.  Her eyes remained closed but her mouth hung open as she panted with pleasure, occasionally letting out a quiet “oh,” or, “ah.”

Applejack wasn’t quit as receptive to the whole thing but she found it to be an interesting experience non the less. She would
poke at her expanding midsection, watching as she left slight indents with her hoof. Although otherwise unimpressed, witnessing herself grow so large was a bit liberating in its own right. Big is what she liked and big is what she was becoming. Looking up from the swelling mass that was her body she watched the white mare with a peculiar curiosity. With their time spent together so far she had become accustomed to the petite and dainty pony that everyone else was familiar with. But watching her grow, and being so into it at that, was something that made her go hot between the legs. And that’s when it struck.

Applejack yelped slightly, trying not to make too much noise for fear of being heard outside the boutique. She bit her bottom lip and scrunched her eyes shut.  What was once plain and uneventful became lively and exciting over the course of one second. Rarity’s ear perked at the sounds of fulfillment. Opening one eye, she looked over at the trembling pony. “E-enjoying the ride?”  Applejack was unable to answer.

After a moment of continuous growth Rarity’s belly had finally reached the ground, encompassing her legs as it swelled. Feeling herself pushing against the floor, she let her body go limp. Supported by her own girth, she closed her eyes and let her mind drift off into nothingness, only focusing on her own pleasure.

Applejack was quick to follow up on forming a plush bed for herself. However, with a distressed squirm she was unable to become nearly as comfortable. Her hooves became useless as they rested on top of her body. She tried to wiggle them but found that any possible movement was severely limited. Dabbed in a cold sweat she watched as Rarity carelessly swelled more and more, oblivious to the fact of just how large she was becoming.

Applejack watched Rarity as her back arched outwards, her head becoming centered with the rest of her body as it inflated above her. She watched as her hooves became puffy and bloated. They began to swell out from the base and rounded out over time, leaving only the very tips of her hooves to be engulfed by the sheer volume. She watched as her head sunk inward, her ears being forced down as the rest of her body seemed eager to swallow itself whole. And as she watched she could feel it all happening to her.

She went through all the same motions until they were both big round balloon ponies. Applejack’s hat toppled over onto the ground, knocked over by her own swelling frame. She tried to move her body but could only muster a few hopeless rocks as she teetered in place. She felt her skin being forcefully stretched, an unfathomable pressure building from within.  “Uh…Rarity?” Her voice had become meek and quite, not usual for the robust farm girl who was accustomed to making a ruckus. Unsurprisingly, no answer was given. “R-Rarity, ah think ah’ve had enough.” Still no answer.

They both continued to expand gradually. Applejack could hear a feint creaking noise, a sound that made her blood run cold. Without magic she was helpless to stop the forceful binge of air. She again tried to move but could only wiggle the tips of her hooves. Even her head had become too entrapped to do much. Only her eyes remained free to wonder and with the ever mounting pressure both were scrunched shut with discomfort. She grit her teeth as more air was added, the creaking noise gradually becoming more present.
Rarity had long ago become lost within her own head. Oblivious to the world around her, the only thing she was aware of was herself and what she felt as she inflated. Her heart felt ready to explode in her chest, much like the rest of her body which began to tremble. The groaning she heard only added to the excitement, something was about to burst and she was more than ready for a round of chicken with herself.
Bigger and bigger. Tighter and tighter. Both ponies were nearing their limits. Applejack had tried to get her partner’s attention countless times but lost hope as not one garnered a response. Rarity, having a first crack at the hose, would be the first one to blow. Her skin turned from snow white to blood red. Sweat coated her fine hairs. She went crossed eyed with arousal, her tongue hanging out like a dog begging for more. Applejack had long since given up. She kept both eyes closed, all the while thankful that her ears were covered so that the resonating explosion wouldn’t be so loud.

“Ah…ah,” No words could be said by Rarity. She knew she was close to exploding but remained adamant in her growth. And then it happened. Her scream was ear shattering. Dribble trickled down from behind her, coating the hose in its wetness. Trembling violently, she barely had enough sense left in her to shut off the hose. With the tank turned off the room again went silent.
Applejack, noticing the cease in air flow, slowly opened one eye. Her heart skipped a beat when she saw that her lover was still intact. Opening the other eye, she couldn’t help but laugh nervously. If her hooves were available this would be the part where she would wipe her forehead while sighing a relieving, “phew.” However, being very aware of her immobility she knew that the relieved sigh would have to do for now.

Finally caught up with her lungs, Rarity looked timidly at Applejack. “So, uh, I presume you enjoyed it as well?”

Applejack grunted. “It was kinda fun up until the part my life was jeopardized. Oh, and being ignored? Always great to see in a relationship.”

Rarity felt her heart sink. “Oh, uh, yes, my, uh, my apologies, Applejack.”

They both remained silent, neither one sure as to what to say next. The piece was finally broken by a snorted laugh from Applejack. “Although, ah do gotta admit, ah’m sorta impressed by how big you got.” Rarity looked up and into the grass green eyes of her partner. “To think such a hussy pony like you could hold it together, ah’d never believe it.”

A bashful smile came onto Rarity’s face. “Heh, yeah. I suppose you could say there’s a lot more to me than you thought.”

“Somethin’ like that. Ah suppose ah never thought you had it in ya.”

“I'd say we both have a lot in us right now.” They both laughed heartedly, the previous tension merely slipping out of the room. After recovering from her giggle fit, Rarity looked sincerely at Applejack. “I really am sorry about this. I was hoping this would be something we both could enjoy and I guess I got carried away.”

Applejack grinned modestly. “Aw, it’s alright. Ah’m certainly no stranger to overdoing it.” They both shared one more laugh and then everything went quiet once more. As it turns out there’s not much that can be done when you’ve turned yourself into a couple of helpless blimps.

After a short session of silence a sudden knocking was herd followed by the sounds of a door creaking open and then being slammed shut. Rarity’s eyes went wide. “Oh no, I forgot to lock the door.” Neither one was able to do anything as they watched Pinkie Pie bounce into the room.

She looked at them with a hanging jaw, her eyes shining with wonder. “Ohh, Rarity I didn’t know you were practicing my new gig.” She trotted over to the white mare and poked a hoof into her taught body, laughing in as it sunk into the sensitive skin. “Very good, and just the right amount of firmness too. Not bad for a beginner.” She looked over to Applejack, skipping to the helpless bundle with a wide smile. “And you even got Applejack to give it a try. Maybe if we showed this to everypony, then we could all have a real blast.” Applejacks’ face went green. A blast is the last thing she was ready to have.

Pinkie continued to hop and skip about the room, rambling on about what fun turning the whole town into balloons would be. Caught up in her wild ideas she stopped mid-sentence when her eyes became fixed on the air tank that was responsible for it all. “Hey, so that’s where that went.” She trotted over to the silver container. “I’ve been looking all over for this. If you  wanted to use it you could’ve asked me first.”

“Oh, Pinkie, was that your tank? I had no idea.” Rarity’s face grimaced as she attempted to keep a straight smile.

“Ah, it’s no biggie. No harm no foul.” She unhooked the two hoses from the valve. “But I really do need this for a party. So if you don’t mind.” She began to drag the tank along the ground and towards the door.

“W-wait, Pinkie,” Rarity stuttered. “ You’re not just going to leave us like this?”

Pinkie looked at Rarity with a sheepish smile. “Sorry, but I’m almost late for today's gig. Just give it time, you should deflate naturally.” She opened the door and swung the tank outside. “By the way, good idea putting the hose in that way. If I try that, I’ll be able to tell jokes along with my act. Anyway, tootles girls.” She shut the door behind her, prompting her exit.

Applejack glared at Rarity. “You’ve done this before. How long does it take for us to deflate?”

“Well, on average it takes about a day for me. But I’ve actually never gotten this big before, so…”

“So, we’re gonna be here for quite a sometime?”

“Yes, yes, that seems about right,” Rarity finished. Applejack continued to maintain her previous glare. Rarity laughed nervously. “Well, let’s be positive. All of the most popular relationship experts say that turmoil like this is good for keeping the bond between to ponies strong.” No response was given and the room remained silent. And silent it remained, for quite some time.
