>”So you’ll help?”
Pinkie Pie was bouncing in excitement as Rarity affirmed with a nod.
>”Certainly Pinkie! I wouldn’t be the element of Generosity if I didn’t help my friend with something as simple as an advertisement!”
>”Great! Follow me to my room Rarity! I’ve got everything we need there!”
As Rarity followed Pinkie up the stairs of Sugarcube Corner, she couldn’t help but wonder what a creative pony like Pinkie could be planning to use as an advertisement.
>”Pinkie, what kind of advertisement did you have in mind?”
As the two entered Pinkie’s room, the party pony replied with a little twirl and giggle.
>”Oh that’s an easy question! Mr. Cake said that I should put out some balloons! And I totally agree with him! I pretty much love balloons in every way conceivable!”
BREAK

Rarity huffed. While she didn’t much like the idea of hanging up balloons with smiley faces, she would persist on the behalf of her friend. But her hopes were renewed with Pinkie’s next comment:
>”But Mrs. Cake came up to me and said that I should set up something pretty for the AD!”
Rarity cracked a smile. Although she preferred ‘beautiful’, ‘pretty’ was another one of her specialities.
>”And I trust that you would come to me for help at satisfying Mrs. Cake’s orders?”
>”Yupparoonies! You’re pretty much the queen of ‘pretty’ in Ponyville! There’s was no other alternative, and being bestest friends helped even more with that decision!”
The duo trotted to the middle of the room beaming at each other, both thankful to have such a good friend.
Rarity sat, eager to begin making designs that would delight anypony who dared to trot past Ponyville’s premier bakery, while the Pinkster went off to grab supplies from her closet.
>”Pinkie, would you be a dear and bring me some stationery?”
BREAK

Pinkie didn’t answer, her head buried deep in her closet. After a while, she gave a squeal of delight as she seemed to have found what she was looking for.
Pinkie hauled out of the closet, an odd red canister, some string, a small silver loop of metal, and a hose with a strangely shaped nozzle… Somehow this whole arrangement gave an unsettling feeling to Rarity…
As Pinkie Pie set the canister down however, Rarity saw that the canister was labeled “Balloon Time: Jumbo Supreme Sized – Cheese Sandwich Approved – Triple-A Grade Helium!”
Rarity relaxed. Pinkie was just preparing to blow up the balloon. HOWEVER, she would still need a paper and pen to craft her masterful designs…
>”Pinkie, would you please bring me some stationery?”
Pinkie gave a little giggle, and a confused look:
>”No silly! We’ve got everything we need! Are you ready?!”
Rarity was greatly confused. Just what the heck was Pinkie saying?
>”Rarity! Are ya ready?”
>”Oh! Er, Um, yes?”
And that translated to ‘Green Light’ in the party pony’s ears, In more ways in one in fact. She would take first in any race with that kind of speed. To put it aptly- she’s off!
BREAK

Faster than exactly ten sixths the speed of sound, The Pink Menace places the ring around the Unicorn’s horn and inserts the hose between her friend’s soft bum!
Rarity fell to the ground, dazed by the blinding speed of her friend and the sensation of being plugged up.
>”Ooh! Pinkie! What ARE you doing!?”
Pinkie was struggling to turn the seemingly stuck wheel of the canister while she answered.
>”Nnnng! I’m making the -ngh- prettiest balloon in Ponyville!”
>”WHAT!?”
That was all Rarity could say before the wheel finally turned.
>*hissssss*
Rarity’s normally trim belly quickly swelled to the size of a watermelon, before Pinkie turned down the valve to slow the inflation. Pinkie trotted up to the now slowly bloating fashionista, who was splayed out on the ground.
>”Nnn… Pinkie… W-what?”
>”Don’t worry Rarity! The first time’s always a little scary, but as long as you have a friend nearby, there’s no danger of popping!”
BREAK

>”P-pop?! P-Pinkie! Shut it off, Please!”
>”You feel like you’re gonna pop?! Already?! That’s not good!
Pinkie dashed to the canister and closed the valve, stopping the helium. Rarity gave a sigh of relief, but Pinkie looked a little sad.
>”Where am I gonna find a balloon as pretty as you, especially one that can blow up big enough?”
>”I’m sorry Pinkie, but I’m afraid it’s not that I’m about to pop, it’s that… Well I just don’t want to be a balloon! It seems too strange for me!
Pinkie looked shocked, and then her mood seemed to deflate, as did her hair.
>”Oh, I understand. I’ll unhook you, sorry for wasting your time…”
As Pinkie slowly moved behind Rarity, Rarity frowned. She hated upsetting her friends like this. Looking at her swollen belly, she gave it an experimental push. The hoof sunk deep into her flesh, and it felt a little good…
Oh Buck it all.
BREAK

>”... Actually, Pinkie-“
Pinkie lit up, returning to her bubbly, frizzy-haired old self. Her smile could only grow more and more painful looking.
>”-Please continue. Even if it seems a little odd, I will do it simply for the sake of trying new things! And for you too, I suppose…”
Without another word, Pinkie was spinning the valve like a record player, causing the hissing sound to return, as well as causing Rarity to balloon further.
>”Ooooh…”
Rarity cooed, the sensation of swelling up and stretching out becoming quite pleasurable, as her belly grew to the size of a medium beach ball. She poked and prodded at it gently, causing cute little squeaks to sound out, followed by a wave of jiggles. She was starting to feel light…
>”Are you doing alright Rarity?”
Rarity said nothing, but nodded just a little, a blush growing on her face.
>”I know how nice it feels, Rarity, I’ve done this myself. Nearly popped the first time too, Gummy’s been my partner ever since. Too bad he can’t help me, y’know…”
BREAK

Rarity understood what Pinkie had meant. It felt really good to just bloat up, but it wasn’t enough. But Pinkie was here so…
>”Pinkie-”
Rarity’s voice came out high-pitched and squeaky, causing the Unicorn to stammer and the Earth pony to giggle.
>”A-as I was saying… Pinkie, you mentioned earlier, how much you loved balloons…”
The Pink pony felt herself blush as she took in Rarity’s words, blushing even harder as she stared at the unicorn’s enormous, round form, which was now at least six feet in diameter.
>”I wasn’t kidding when I said every way conceivable…”
Rarity, mind clouded with lust and pleasure, gave a sultry look.
>”Well, come on then! This big balloon is in need of loving!”
Pinkie Pie’s breathing started becoming shallow as she found herself nearly dripping already, more red in the face than pink.
BREAK

As Rarity waited for Pinkie to snap out of her stupor, she attempted to rub herself more, but found her hooves half sunken into her giant midsection. Instead, she bounced herself impatiently. Soon enough, Pinkie came to her senses and wiggled her rump in anticipation
>”OK Rarity! I’ll just need to get you tied down so you don’t float off while I’m playin’ with ya!”
After a short fiasco with some tangled up string, Rarity found herself snugly tied down, and nearly full…
At fifteen feet in diameter, creaks and groans were beginning to emanate from Rarity’s immense form, each one sending shivers down the party pony’s spine. Pinkie shut off the valve and crouched down, like a cat ready to pounce.
>”Ready Rarity?”
>”I’m definitely ready this time, Pinkie.”
With a squeal, Pinkie Pie leapt to Rarity’s midsection with and squeezed.
BREAK

Pinkie Pie’s soft hooves sunk into Rarity’s swollen hide, causing loud creaks to echo throughout the room. Rarity moaned, the pressure causing her to feel even the slightest breeze as an assault on her senses.
Pinkie giggled.
>”You are so soft Rarity! I wanna squeeze you more!”
Pinkie squeezed again, harder this time, causing Rarity to give a small belch. Rarity blushed in embarrassment, not used to such uncouth actions, but the slight decrease in pressure was both relieving and refreshing.
>”Oooh, how rude of me!”
>”Aww, It’s ok Rarity! I do it all the time!”
Rarity groaned, her fragile hide only barely able to take the stress Pinkie was repeatedly putting on her blimped up body. Suddenly, Pinkie hugged Rarity harder than ever before. Rarity felt a little bit of pain, but Pinkie let go quickly.
>”Mmmf, Pinkie not so har- OOH!”
Pinkie gave Rarity’s bouncy side a tough slap, marking the area in red and causing the swollen mare to quiver.
>”Sorry Rarity, but it’s high time I got a little rough with you!”
BREAK

Rarity was a little frightened by the way Pinkie had said that. Straining to see, Rarity saw that Pinkie’s mane and tail had gone straight, and her friend was wearing a teasing smirk.
>”Pinkie wha-“
Another slap caused the alabaster blimp to moan, interrupting herself. The mild pain of being abused as so was becoming unbearably pleasurable…
>”Quiet Rares’! I’m tryin’ to think of what to do with you!”
Rarity didn’t care. She just wanted to be toyed with, played with, batted around like a piece of cheap plastic and stretched to her very limits and then some. Maybe even getting popped would feel nice. Meanwhile, Pinkie seemed to be getting somewhat frustrated.
>”Guh! I can’t think of anything! Maybe the answer will come to me as I punish my dumb balloon for making me forget!”
Slowly, Pinkie began walking around the white sphere, licking her lips every few steps. Rarity shivered, Oh how she wanted to be touched! But alas! Her mistress would not! Rarity moaned impatiently, setting Pinkie off.
>*WHAP!*
Her hide reddened as she jiggled wildly from the impact, the rest of her body protesting with a delicate groan. Pinkie chuckled, moving on to the next spot…
>*WHOP!*
Rarity grunted, her fragile white complexion would be ruined from these blows! She struggled weakly, before slowly relaxing into horny bliss once more…
>*FWAP!*
Rarity squealed in pleasure, feeling her privates tingle and ache as the stress only grew, tenfold. She was starting to feel somewhat wet…
BREAK

Pinkie snorted cruelly as she continued her fourth circuit around her inflated friend, but stopped just behind Rarity’s bloated flanks, raising an eyebrow.
>”Huh, I don’t recall making a water balloon. It’s leaking too, such a naughty balloon…”
True enough, Rarity was already slick with fluid, dripping constantly and messing everywhere. A devilish smile spread over Pinkie Pie’s face. This was gonna be fun…
>”Aaaahahaha!”
Rarity screeched as Pinkie traced her hoof along her friend’s swollen lips. Making certain that she would not cause her friend to climax, she poked and prodded at Rarity’s vagina, causing it to emit a drawn out, rubbery squeak. Pinkie giggled.
>”This balloon is just the worst! It won’t stop talking, it magically changes helium to water and on top of all that, it leaks!”
>”I’m such a naughty balloon! I need to be punished oh so badly!”
In response, the Pinkster grabbed the white mare’s flanks, channeled her innate earth pony strength, and gave a mighty squeeze…
>*Creeeaaaaak…*
>*Grooooaaan…*
>*Squeeeaaak…*
BREAK

The pressure was incredible, Rarity’s delicate skin becoming taut and transparent. Despite the danger of bursting her friend, Pinkie only squeezed harder. The sounds of a full balloon became louder and louder, mixing with Rarity’s moans, wails and squeals, until an oddly out of place sound was heard…
>*POP!*
The pressure dropped, causing Rarity to sigh and Pinkie to stop squeezing. As Rarity felt Pinkie’s hooves disappear off of her massive ass, she felt herself being poked and prodded along her sides. Suddenly, Pinkie appeared right in front of Rarity.
>”What was that!?!”
Rarity did not answer. Pinkie grumped. Deciding to find out for herself, she pushed Rarity’s belly, causing her flanks to meet the ground. On the underside of Rarity’s belly did Pinkie Pie find her answer.
>”Hee hee! Look Rarity! You’ve got a giant outie!
True enough, Rarity’s navel had swollen to the size of a watermelon, most likely pushed out in reaction to the pressure. However, Rarity was somewhat concerned about Pinkie’s second change of demeanor. Looking to her friend one again, she saw that Pinkie Pie’s mane and tail had puffed up to their usual state. Rarity was unsure whether to feel relieved or disappointed with this change.
BREAK

Pinkie gave the massive belly button a carful prod, then a slow lick. Both actions caused Rarity to moan and shudder. Suddenly Pinkie lit up.
>”Rarity! I just got the bestest idea of what to do with this bellybutton of yours!”
Pinkie dashed into her closet once again, rummaging around in the garbage until she found what she was looking for: A totally nondescript leather belt (+4 Strength +4 Stamina!). Next, she disconnected the hose from the canister and brought the canister in front of Rarity, so she could watch.
>”I’ve never done this before, but I got a good feeling that it’ll work!”
And with that, Pinkie fastened the belt around her waist and placed the tank on its side, nozzle up. Cranking the valve up to max, Pinkie Pie did nothing more than sit on it.
The effect was immediate: Pinkie’s flanks swelled to the size of Rarity’s and then a little bigger, Jiggling and rippling as it blimped to impossible sizes. Pinkie moaned, swaying her hips from side to side, knocking objects off shelves and filling the room with a wall of pink. Once they were good and tight, Pinkie stood, turning around to shut off the valve, exposing her massive rear to the unicorn.
Pinkie cantered over to Rarity, looking oddly unhindered by her immense rump. Each step caused Pinkie’s buttcheeks to rub together, making sounds like rubbing balloons, and causing pulsing waves of pleasure to rock the party pony’s rump. With a giggle she pushed Rarity onto her back, leaving her giant navel atop a squishy white mountain. Pinkie clambered up, looking at the navel with lidded eyes, feeling horny as all hell…
>”What in Celestia’s name are you doing Pi-OH!”
BREAK

Pinkie sat atop the melon-sized bellybutton, grinding and bouncing her butt, causing both ponies to squeal in pleasure. Pinkie’s rump creaked and protested as she forced the navel inside of her, filling her perfectly and squeezing the navel from every angle. Both gasped as they felt stuffed tight, with Rarity’s body being squished by Pinkie. Pinkie gave each of her flanks a spank, causing her to moan in ecstasy as they wobbled.
>”Pinkie, I-I’m gonna-ah…”
And Rarity came, letting loose all of the pent up stresses and lust she had stored. Unfortunately, she let another thing she had stored loose too…
>*Hissssssss*
Rarity’s navel opened, causing the helium to leak into Pinkie, who’s flanks swelled up further. The Leather Belt strained, and finally broke, letting air into the rest of Pinkie, who moaned and jiggled as Rarity’s gas was added to her own. Pinkie’s body creaked and groaned, as Pinkie herself squealed with pleasure, her cheeks bulging out like the rest of her.
BREAK

Soon, Rarity’s navel had shrunken to the point that Pinkie could float off of it’ and up to the ceiling, where she continued to rub and grope her belly. By now, Rarity had deflated completely. Still red faced and sweaty, she removed the magical limiter from her horn and using her magic to give Pinkie an experimental poke. She was rewarded with a loud squeak and a shower of liquid. Rarity giggled. It seemed that was all that Pinkie had needed.
>”Well Pinkie, It has been a delightful evening, but I am afraid I did not expect to spend so much time with you! I really should be going by now, Celestia knows that I’m going to have to get cleaned up…”
>”Haaaaaah, haaah, W-wait Rarity, If you’re going to go, will you at least give me a kiss goodbye?”
Rarity sighed, but levitated the pink balloon to the ground in preparation.
>”Very well, Pinkie. I suppose after all that we’ve been through, a kiss goodbye is only customary…”
Pinkie beamed. What a Sucker.
BREAK

Not half-an-hour later, Rarity found herself once again fully inflated. Hanging from a street corner with the words “Special sale at Sugarcube Corner!” shoddily painted on her side, she wailed.
>”Oooh, oh! Somepony get me down! Somepony rub me! Oh Celestia, I look fah-ha-hat!
