Rarity treats Applejack to a lavish spa day in Manehattan! But what happens when the treatment is so good that they just can't get enough...?

Back again! This time with a VERY long overdue request from a friend about some Rarijack ballooning~

Hope you enjoy!

----

The bustling metropolis of Manehattan was as busy as ever, with carts running both ways on the road and the sidewalks jam-packed with earth ponies and unicorns rushing to get where they needed to go. Pegasi wisely took to the airspace above them, making much better time.

A sea of multicoloured coats and manes emerged from the train station and down the steps onto the street; two of which were an orange earth pony with a blonde, ponytailed mane and tail, green eyes, a cowpony hat on her head, and a trio of apples as her cutie mark; and a snow-white unicorn mare, with a beautifully curled, purple mane and tail, sapphire-blue eyes, and a trio of diamonds as her cutie mark.

"Aaah, dearest Manehattan," the unicorn sighed fondly, in a rather upper-class accent, "How I have dearly missed you! Your glitz! Your glamour! Your fashion!" She practically squealed the last word.
"How can y'all be excited to be back in Manehattan already, Rarity?" The earth pony chided playfully, smiling with a shake of her head, "Last time we were was fer the Midsummer Theatre Revival, and that was only a few months ago."
"How can you not be excited, Applejack?" Rarity chirped, her eyes practically glistening with excitement, "Doesn't all the hustle and bustle get you excited to hit the streets?!"
"Actually, it just makes it hard fer me t'cross the street," Applejack snarked quietly.

Rarity, either disregarding or not even noticing her friend's comment, turned her sights back onto the tall buildings and rushing pedestrians.
"Now then, my friend," she began, beginning a strut along the concrete path, "there is a reason for the two of us to be here."
"Y'all sure?" the farm mare asked sceptically, craning her neck to look down at the apples on her flank, "'Cuz Ah don't remember seein' mah flank glowin' before y'all came over."
"Oh, it's not that kind of important," Rarity smiled, waving her hoof dismissively, "You see, everything has become much calmer, and, between us, Canterlot Boutique has practically been booming with business! So much so, that I - get ready for this - have booked us the most prestigious spa treatment money can buy!"

Rarity squealed and pattered her hooves, while Applejack just raised an eyebrow at her.
"Riiiiight...and why couldn't y'all take Fluttershy or somethin'? She loves all that fancy-pants pamperin' stuff."
"Ah, but here's the thing," the unicorn went on, smirking, "I actually spoke to Fluttershy about this, and we both agreed that out of all of us, the hard working farmhoof deserved a day off the most!"

The earth pony opened her mouth to protest, but she began to think; it wasn't exactly a busy season, and harvests weren't huge around this time of year. Big Macintosh and Applebloom could handle it, she was sure. Besides, it was only for one day.
"Well," she muttered, putting a hoof to her chin, "Ah suppose Ah can take one day off..."
"That's the spirit!" Rarity giggled, and ushered for her friend to follow her as she began along the sidewalk, "Come, come! Our girls' day out begins now!"

Applejack could only blink and follow her friend's lead. She had no clue what she was getting put into, or if she was going to like it.

----

Being quite a shopaholic, Rarity had intentionally arrived into Manehattan early, to get a few hours of shopping done before the big spa treatment. Dresses, jewellery, hats, mane and tail accessories, if she could afford it, chances were she bought it. Applejack simply allowed her to do her thing, and occasionally model the odd dress for her. She wasn't big on the whole big spending thing, but she wasn't exactly having a bad time.

Plus, Rarity had gotten her a necklace with a stained-glass apple for a pendant, which reminded her a lot of her Element of Honesty, and she had to admit, it was quite pretty.

Eventually, the time had indeed come, and Rarity trotted her way through the crowded sidewalk, many bags hovering with her in a light blue aura. Applejack followed behind, only having that necklace. She kept offering to take some for her friend, but she kept insisting she could handle it. And she was proving herself right so far.

The duo arrived at a large and rather fancy looking place known as Marevana. Rarity tittered at the play on words, but Applejack, being a more simple pony, didn't get it.
They entered through the double doors, and walked up to the reception desk. A unicorn mare with a pink coat and dark purple mane sat behind it, and beamed a smile as they approached. Applejack couldn't help but notice that this mare, while looking incredibly healthy, was a bit on the plump side.

"Welcome to Marevana!" The mare chirped, cheeks dimpling from her smile, "Do you have a reservation?"
"That we do!" Rarity smiled back, and levitated two tickets toward the receptionist.
"Oh, wow," The receptionist gasped, gazing at the tickets and taking them in her own magic, "The Pampered Princess Package! It's not every day we get reserved for these."
"This is a particularly special girls' day out," grinned the Element of Generosity, giving her friend a playful nudge, "this workhorse needs a good break."

Before the earth pony could get a word in, the receptionist spoke up with a nod. "Oh, I can tell from here that she's rather tense! I'll let them know you're coming!" With that, she pushed a button on an intercom. "Soothing Incense, your three-PM is here."

Applejack just turned to her friend with a raised eyebrow. "What're y'all talkin' about tenses n' stuff for?"
"Oh, she's just saying you look rather overworked, dear," Rarity assured her, putting a hoof to the farm pony's upper foreleg, "Oh, she wasn't kidding!"
"Hey, Ah feel perfectly--" Applejack stopped in her tracks when she saw the concern on the unicorn's face. "...well, Ah suppose Ah've been kinda busy lately. Harvests've been pretty big n' all."
"Exactly!" The snowy mare nodded, "Trust me, you'll be glad you did this."

"Excuse me," the pudgy receptionist spoke up, "They're ready for you now. Take the lift to the top floor. Enjoy your stay!" She smiled.
"Thank you darling, we shall," Rarity chirped, and nodded for her friend to follow as she made for the elevator, "Come along, Applejack, we have some pampering to receive!"
"Pamperin'?" Applejack muttered under her breath as she followed, "S'at gonna hurt?"

----

The elevator ride took about a minute, which Rarity spent pattering her forehooves on the floor in excitement while Applejack wondered just what she was getting into. She wasn't into the whole spa treatment thing; it was something more Fluttershy's speed, really.
The plethora of shopping bags her friend stuffed into the lift with them made the earth pony fight them for standing room.

With a soft ding, the soft whirr of the elevator's motor ceased and the double doors split open. The two mares walked out, and entered the room. A tall, white shag carpeting brushed on their hooves, feeling like they were walking on the fluffiest clouds. The faint, pleasant aroma of lavender filled the air, putting the two at ease. Even Applejack was starting to relax.

An earth pony mare walked toward the two Elements of Harmony. She had a shimmering lavender coat, which quite literally sparkled like a jewel. Her fuchsia mane was brushed rather beautifully, enough to make Rarity give her own stylish hair a self-conscious adjustment. The glimmer in her light blue eyes had a jagged, hexagonal look to it. The final clue that this mare was indeed a crystal pony.

The two mares couldn't help but notice she had quite a curvaceous figure; nicely rounded, with a perfectly rounded flank with swayed side to side as she sauntered up to them. She was quickly flanked by a pair of unicorns who, while not as large as the crystal pony, were still quite nicely rounded.

"Welcome!" The glimmering mare smiled, her chipper greeting sounding almost unfitting with her mature voice, "You're the lucky mares getting the Pampered Princess Package, yes?" She held out a hoof toward them.
"That we are, darling," Rarity confirmed with a smile, taking her hoof in a shake, "I am Rarity, and this is Applejack." The earth pony in question just gave a meek tip of her hat.
"A pleasure," she larger mare smiled back, "I am Soothing Incense, the owner of this little salon. I'm sure you can't wait to get started."

"No, we certainly can't!" Rarity grinned, her curled tail swishing with excitement.
"Ah could stand t'wait a couple minutes," Applejack snarked under her breath.

"Splendid!" Incense chirped, and waved a hoof toward the massage tables, "If you'd like to make yourselves comfortable? Oh, and let my lovely mares here take your bags."
"Oh, why thank you," Rarity smiled, and allowed the two unicorns to take her shopping bags, "Shall we, Applejack?"
"Ah guess so," The earth pony shrugged, and walked over to the massage table.

When Rarity's things were set at the side of the room, the mares trotted back over, ready to go.
"Oh," one of them spoke up, and her horn began to glow, "Allow me!"
Applejack blinked, and glanced up as she felt her hat being lifted from her head. "What the-?!"
"Not to worry," Incense chuckled, "We're just hanging it up till you're finished. No need for a hat where you're going, hm?"
Applejack blinked and put a hoof to her head, feeling strange without her trademark hat resting on it. "Ah guess not...?"

The two guests got onto the massage tables and laid down on their fronts, faces peering at the floor through the holes. Incense's assistants stood behind them and got to work, pressing their hooves down between their guests' shoulder blades.
"Oooooh!" Rarity purred, stretching out her legs in comfort, "Oh yes, that's the way~"
Applejack didn't say anything, but she let out the slightest shudder from the massage. She had to admit, it did feel quite nice.

Thanks to the holes in the tables, the mares could breathe easily as they stared down at the floor. Both mares were feeling their eyelids get heavy when suddenly something was shoved into their view. It looked like a platter of fruits and desserts, and a rather generous one at that.
Their ears flicked as Soothing Incense spoke up. "I find a nice snack during a massage really puts the body at ease as well as the mind. A good blend of fruits and sweets always delights the palette, don't you think?"

The unicorns began working double duty, using their magic to levitate various treats to their guests' mouths while massaging them. Rarity happily accepted a grape, while Applejack sheepishly took a chocolate chip cookie.

Rarity swallowed and grinned, licking her muzzle. "Oh, I concur! I always love a good bit of ice cream, myself."
"I'm sure we have plenty of that as well," purred Incense, "If that is what you desire~"
"Oh, only if it's no trouble, darling," The snowy unicorn added, "I'd hate to be a burden."
"Nonsense," the crystal mare chuckled, "This is your day, ladies. It isn't called the Pampered Princess Package for nothing, you know~"

Rarity gave a little moan of delight, though whether it was from the massage or the thought of being treated like royalty, she wasn't so sure herself. "In that case, if you have any chocolate and mint, that would go down a treat right now!"
"Coming right up," Incense nodded, and looked toward the orange earth pony laying down, who had been quiet for a while, "And yourself, miss Applejack?"

Applejack was indeed quiet; she was contemplating whether or not she'd enjoy being treated like, well, a princess. All this massaging and being hoof-fed - or magic-fed, in this case - was so foreign to the country girl.
Then again, she'd feel bad if she turned down the offer; Rarity specially invited her to this, and she must have spent quite a bit of money on it. The least she could do was give it a shot. And besides, it was only for a day.

"...y'all got any apple fritters?"

----

As the hours passed by, Rarity and Applejack's pampering continued. The massage was followed by a soothing hoof soak; laying with their hooves resting in comfortably warm water while being hoof-fed more delicious treats. Next came a mane and tail wash, with the finest smelling shampoo Rarity had ever come across. And she has tried more than a few.
Leg massages, pedicures, mud baths, everything was at their disposal. And Rarity was more than happy to take full advantage of it. Even Applejack was starting to ease into it, really enjoying how gently and nicely she was being handled by Soothing Incense and her assistants. The two unicorns were giving most of the treatments, but sometimes Incense herself would take over to provide some amazing leg rubs.

One thing the mares never really clocked onto, was the large abundance of food. In every section of treatment, they were offered delicious fruits and treats to dig into while they were pampered. Grapes, apples, cupcakes, cookies, fritters, ice cream, even some mixed together at their request, all being fed to them by hoof or magic.

When the two had finally gotten some alone time in the sauna, it was time to reflect.
"Ah reckon Ah was bein' a bit silly," Applejack smiled to her friend, "Doubtin' this place and all. This was pretty fun."
"I knew you'd come around," Rarity giggled, returning the smile, "See what happens when you give new things a chance, dear?"
"Ah don't really get this sauna thing, though," The earth pony huffed, wiping sweat off her brow, "Are we supposed to be gettin' all sweaty?"
"Why, of course!" Chirped the unicorn as she stretched out her legs, "Ahhh, sweating out all that stress, you know~"
"Well yeah, suppose that makes sense," Applejack nodded, and copied her friend's stretching, "Hoowee...y'know, Ah wouldn't mind givin' all this one more round. All this gettin' massaged, and all that food!"

The earth pony rested a hoof on her middle at the mention of food, giving her muzzle a greedy lick. What she hadn't seemed to realise though, was that from all her being relaxed and fed, her stomach had gotten a cute roundness to it, making it look like she'd swallowed a hoofball.

"Oh, I know!" Rarity agreed, letting out a small squeal of delight, "The little treats are exquisite! I've never heard of a spa that feeds you during massages, but I'm not complaining!"
The unicorn hadn't realised Applejack's little bloat...or her own, for that matter. Having a much stronger sweet tooth than her friend, Rarity had gone for far more ice cream and cakes, leaving her belly with a moderately larger paunch. Even when she gave it a content rub, the snowball of a belly went by completely unnoticed.

"I'll tell you what," The Element of Generosity went on, a cheeky little grin on her face, "How about I get us scheduled for another session?"
"Really?!" Applejack gasped, grinning with excitement before it dissolved into a curious frown, "Wait, didn't this cost a lot? Ah'd hate to bankrupt ya or somethin'."
"Oh, perish the thought, darling," Rarity giggled, "Having two successful stores has left me with quite the disposable income. I could afford a session a week if I wanted!"

They looked each other in the eyes as they registered that last comment. A Pampered Princess Package session at this very spa, once a week. All that amazing massaging and delicious food, all for them.

"...should we?"
"We should."

----

And so it began. One day a week, Rarity and Applejack began meeting up for day trips to Manehattan for shopping and hours of relaxing at Soothing Incense's spa. Every time the girls visited, the crystal pony practically shimmered with delight each time, like she was getting happier and happier to see them. The massages grew more abundant and passionate, and the platters of treats grew larger and tastier.

Of course, those weren't the only things growing.

As the girls' visits continued, their bodies were becoming more used to the special treatment they were receiving. Rarity, once a svelte little thing, had gained quite a collection of curves. Her belly drooped down between her thicker legs in a round pendulum, with a nicely rounded rump to go with it. The diamonds on her flanks had expanded to fit along her larger rear, which had developed quite a sway to it when she sauntered around Ponyville and Manehattan. Her face had grown rounder, with a pair of pink tennisball-like cheeks and a slab of double-chin.

Applejack wasn't faring much different. Being a dedicated workhorse, her body was toned with muscle, but it was becoming lost in the onslaught of adipose that came with her new sedentary pastime. Her backside, already toned and rounded thanks to years of apple bucking, had gained quite a few inches of jiggle to it, stretching the three apples on its sides. While Rarity's growth was spread across more evenly, Applejack's went mostly to her backside, giving her quite the rump. Her belly, legs and face were still quite rounded, but not at her friend's level.

Mares and stallions alike would stop and stare at the two large mares as they sauntered down the street to the spa, their backsides bouncing and swaying side to side in their gait. Walking side by side, they took up almost the entire sidewalk, causing ponies to brush against them as they passed. Some frowned and tutted their annoyance, while others gave a meek double-take with redder faces. Some foals stare in sheer wonder at the biggest ponies they'd ever seen in their lives.

The only time they weren't side by side was in the spa building. They'd learned that by going in that way would cause their larger backsides to squish together and get stuck between the door frames, which they both chalked up to the doorway being too small. It was the same case with the elevator, which they now had to take one at a time. It was by then that they'd start feeling tired, and have to take a seat in the elevator to catch their breath. Even Applejack found herself huffing and puffing.

Once the two were in the prestigious spa room, Soothing Incense approached with a knowing and pleased smile. Almost as if she expected the sudden change in the mares' girth. Even she and her unicorn assistants looked larger than before.
"Good afternoon, ladies," she greeted them, "The usual?"
"Naturally," Rarity purred, her voice an octave lower thanks to the fat pushing on her vocal chords.
"Yup," Applejack grunted, her deeper voice breathy from huffing and panting, "and plenty'a fritters."
"Of course," the crystal pony smirked, and watched as her favourite guests lumbered to the massage tables and, with a bit of time and effort, flopped down onto them with jiggling thuds.

The unicorns grinned and got straight to work, pushing into each mare's body to start the massage. The increase in layers of fat meant they had to squish and knead into their blubbery forms to make an effect. Not that they minded of course; in fact, all that soft furry mass squishing against their hooves felt rather pleasant.

Applejack and Rarity weren't exactly uncomfortable either. Seeming totally oblivious to their growth, feeling the massages intensify only seemed to relax them even more, so they simply laid limp with content, almost drunk smiles on their faces, dimpling their cheeks and making slight squints in their eyes.
Another thing they hadn't clocked onto was the increasing sizes of treats offered to them. Whole cakes and tubs of ice cream were becoming offered to them by their massive hostess, as well as some apple pies and cobblers for Applejack. And naturally, the girls accepted them with gluttonous gusto. Manners seemed to jump out the window as they scarfed down the snacks, getting drops and crumbs on their chins and being lovingly dabbed clean with a napkin by Incense, who seemed rather happy about the whole situation.

The two Elements of Harmony were not only growing larger; thanks to getting used to being so pampered and spoiled, they were getting lazier too. Applejack's tree bucking was becoming far more lackadaisical, using far less effort and becoming more insistent on taking breaks for a snack or a nap. Rarity's dressmaking was taking double the time it normally would, taking days to finish what she might have had a few of done in hours.
Their friends and family, of course, noticed their radical changes, which were promptly shrugged off or excused as nothing a quick snack or nap - or both - wouldn't fix. Predictably, this outlook only worsened their habits.

Thanks to the constant spa visits, Rarity and Applejack had bonded and become much closer than ever before. Frequent meetups, whether at the local Ponyville salon or at their own homes, had become a regular activity during their waits for the big Manehattan day. They weren't nearly as good as Soothing Incense's heavenly treatments, but they would do nicely.
Sleepovers would involve them performing spa treatments on each other, including facials and massages. Neither of them knew why, but the latter was their favourite part. Getting to rub over each other's large, plush bodies was oddly soothing and exciting, in a way.

And thanks to Soothing Incense's treatment, there was no stopping them.

----

Days became weeks, which became months. And at last, the final nail was struck on the metaphorical coffin.

During one of their sleepovers, this one at Rarity's, the mares had worked together to splurge some money on a serious pile of treats, which they spent all night devouring while giving each other rather enthusiastic massages. Every last crumb and drop of junk food and cider disappeared into their gluttonous mouths.

It proved to be their downfall in the morning, when they both woke up to realise they had seriously grown.

Rarity was less of a snowball with legs and a head and more of a gigantic, room-filling dollop of vanilla ice cream with folds of what used to be limbs and a neck, with a blubbery mass of face at the front and an almost comically small curly tail at the back. Even her horn seemed thicker than before.
Her legs had become sucked in by rolls of white furred blubber, with tiny thick nubs for hooves that could barely wiggle. A plethora of chins spilled down her front, with a pair of pink, saggy cheeks that nearly caused her eyes and mouth to vanish. Her enormous thighs sat levitated, with her cutie mark stretched out into a trio of thick diamonds.

Squished next to her was the slightly smaller but still immense blob of orange and blonde known as Applejack. Her belly wasn't as large, and her legs weren't completely sucked into their fat, but her hooves still couldn't reach the floor.
Her rump had become much much larger than Rarity's, each flank about the size of a carriage with three big fat apples covering them.

Both mares were peppered in dimples of blubber, their once nicely rounded bodies more bloblike and squished out into creases and folds.

"Oh, dear..." Rumbled Rarity, her voice much deeper from the immense flab pushing on her throat, and slowed from utter laziness, "Shomething tellsh me, we might have overdone it a little..." Thanks to the cheek fat around her mouth, she had developed a bit of a lisp.
"Y'all think sho...?" Applejack mumbled, pausing for a long, lazy yawn, "Ah think, lasht night went pretty well..."
"Oh, ash do I..." The white mass chuckled, sending a bouncing, rippling wave through her blubber, "But, today ish our shpa day, darling..."

Applejack's squinted eyes blinked slowly as she thought about this, then scowled as much as her fattened up face would let her. "Aww shoot. What do we do...?"
"I have, an idea..." Rarity mumbled, and used her magic to lift the phone from a desk and dial a number, "Hello, Mish Inshenshe? Yesh, we have a problem. Oh, how did you guesh? ...you'll be here shortly? Oh, thank you, very much!" She smiled and hung up.

"Ah take it, it'sh good newsh...?" The fat farm pony muttered, sounding like she was about to fall asleep again.
"Great newsh, actually," Rarity chirped, "She will be coming to ush today! Pershonally!"
"Yeehaw...!" Applejack yawned, wiggling her massive flanks with joy, "Thish jusht, keepsh gettin' better...!"

It was only a few hours' wait until a familiar crystal pony emerged through the door of the mares' room, and she seemed to shine even brighter from seeing her favourite guests so enormous. She never thought they'd get this big, but it was a great sight to see!
"Well, maybe it's a good thing I brought some more help," she purred, and a small army of well groomed, but rather pudgy mares marched into the room, surrounding the two blobs, "Okay girls, you know what to do~"

The tiny mares nodded and happily got started, splitting into teams to massage each part of the mares' bodies. A small force was working on one of Applejack's flanks, another worked on the side of Rarity's blubbery belly, a group of pegasi eache massaged both mares' fat faces, and all the while, servings of cake and ice cream were floated up via magic to their mouths to devour. Deep, slow chuckles of pleasure rumbled from both mares, their quaking flab bouncing harmlessly against their servers.
Soothing Incense herself would sometimes get involved, massaging one mare after the other in different areas.

The crystal pony was more than pleased with how enormous and lethargic her guests were; after all, if they knew the common side effect of the Pampered Princess Package treatment was an addiction to being spoiled rotten, would they have gone for it?
She giggled at the thought and continued to knead Rarity's warm, blubbery belly side, smirking from feeling the small surges of chuckles.

The enormous mares, meanwhile, had temporarily lost themselves in a sea of greed and laziness.
"Thish ish the life~" They both purred.
