Rarity's new balloon.

“So what’s this all about sugarcube?” Applejack asked raising her eyebrows.


“Oh, nothing too serious my dear,” Rarity said, closing the last set of blinds in her boutique. She turned toward her guest and pointed her horn directly at the earth pony magically grabbing her limbs and holding her in place.


“Hey! What’re ya doing ya crazy mare?” Applejack protested. Rarity felt the stubborn pony’s struggling through her magic shackles and redoubled her effort bringing the strong earth pony under her control.


“You see, I saw something the other day, something that made me feel like nothing else has before, Rarity said, walking closer to her scowling captive. “When i saw my dear spikey take those bellows to you... well, let’s just say it had a rather profound effect on me. I found myself replaying that silly scene again and again in this mind of mine. The way your midsection bloated outward, Those puffy cheeks as the air rushed inside your expanding body, that huge bulging belly that made you look quite ridiculous, yet beautiful at the same time. I keep seeing it and wishing i could have done something other than watch the massive quantity amount of air force its way out of you.”
Rarity produced a set of bellows and gave them a quick pump demonstrating their efficient air moving power.


“Honestly dear, I wanted you to be bigger, much bigger, and I wanted you to be mine: my big billowing balloon,” Rarity said with lust in her voice as she started rubbing Applejack’s taut belly with her hoof. Just saying these words aloud made her marehood drip with excitement.


“Ya’ll cant be serious! Tweren’t fun and games for me! I don’t know bout ya’ll, but i dint fancy none being a party dcoration!”
Rarity pushed the earth pony to the ground belly up and straddled her muscular stomach. She aimed the bellows threateningly at the earth pony’s mouth.
“I assure you Applejack, I’ll make it worth the trouble.”

“Rar-OOMPH!“ Applejack was cut off mid-sentence by the bellows being pushed into her mouth. Rarity pulled the bellows apart letting them fill to their maximum capacity. Rarity stole a final glance at Applejacks face, an expression of impending terror clear on her face. With one smooth motion she closed the bellows. The effect was immediate as AJ’s eyes shut fighting the sudden influx of air, futilely of course. Rarity felt the slim taut belly beneath her puff outwards in a comical fashion, touching Rarity’s soft underbelly pleasingly. She felt her dripping marehood leak onto her precious new possession and pulled back on the bellows again.


Again she was rewarded with a steady increase in size and pressure as the soft cushion beneath her expanded again. Her mind lost to lust, she began pawing at her needy sex, feeling the fluids spreading everywhere. One thought  consumed the unicorn’s mind.


Bigger!


With reckless abandon, she started pumping the bellows even faster feeling the mare beneath her swell larger and larger. She began pawing all over AJ’s swollen parody of her normally muscular self, and even started grinding her needy lips against the tightening cushion of a pony.


It just wasn’t going fast enough though. Applejacks body, now larger than Rarity’s king size bed, just wasn’t blimping as fast as she desired. She thought of a way to accelerate the process. She ceased her grinding and hoofing long enough to turn around and head straight for AJ’s own marehood. Rarity’s mind, already addled by lust noticed AJ’s own dripping and winking sex, apparently she was somewhat enjoying this too!


Rarity took a deep breath in a final act of cognizance and pushed her muzzle deep into AJ’s already lubricated sex and exhaled inside.


A sudden and sharp moan let her know it didn’t go unnoticed by the earth pony. Better still, the expanding balloon-like belly of her friend noticeably puffed up in size beneath her bringing her excitement to a boil. Pleased with the results, she greedily gulped down more air and began expelling more and more of it into her friend. She continued breathing into her partner inflating her at a frenetic pace and occasionally licked at her friends dripping sex, stopping only when she felt light-headed. It was a slight shock to her system however, when she breathed yet another gulp of air into the earth pony and was rewarded with a spray of fluids directly in her face, in any other situation, she should probably be horrified, instead, she intensified her grinding against the earth pony’s blimping belly, her marehood making obscene wet and squelchy noises against skin which by now was making squeaking noises anytime she moved. Lost in the throes of self pleasure she barely noticed her flank hitting the ceiling. It dawned on her that she needed to finish her needs and soon or risk popping her new toy.


“Applejack.....hah... I never  imagined ... Hah. That this could be... so... so wonderful.” Rarity uttered between moans.  She had stopped blowing into her friend’s sex but kept the bellows pumping, she didn’t want to stop until she had finished herself off. Part of her screamed that she needed to stop, that her friend was in danger, heck, even her shop was in danger! But she was pinned to the ceiling and unable to grind any further, she simply squeezed a hoof beneath her causing a loud squeak of protest from her Applejack’s tight skin. The squeaking rose in volume driving her even crazier. She used her other front hoof and began slamming the earth ponies tautly stretched body. With each slam she was rewarded with a hollow drumming sound which echoed dangerously throughout the massive balloon pony’s skin. Finally pinned firmly against the ceiling, the skin of AJ’s belly conformed around her sealing her inside an air tight pocket.


With one last rub, she came dripping her mare juice all over her balloon. She gasped for air in the the tiny little pocket of taut skin around her and involuntarily bucked her hips in the throes of an orgasm causing Applejack’s balloon belly to creak dangerously in protest.
She felt her magic falter and dimly heard the bellows fall out of the earth pony’s mouth and clatter to the floor. The sound of rushing air escaping a balloon filled the air as the creaking subsided. Rarity felt herself get lower and lower to the ground as the air gushed out of the earth pony. Before she knew it, she was panting, out of breath on top of Applejack’s now normally muscular belly, the earth ponies dripping marehood staring back at her. She felt Applejacks hooves gently push her onto the floor. She didn’t know what was going to happen now, but she couldn’t do anything to stop it now. Applejack stood before her, soaked in Rarity’s juices and a dangerous gleam in her eyes.


“Rarity, I want you to know, I would break your spine right now if that hadn’t felt like nothing I’ve ever experienced in my life,” Applejack said, her face taking on a more sultry expression.



“I... I know darling... I just had to take that chance though,” Rarity said, a sudden pang of guilt in her voice


“Ya know, since ya’ll were so keen on blowin me up like ya’ll’s personal parade balloon, maybe you should get a taste of how it feels. I bet your fancy flank might take well to a garden hose, or maybe I could get Pinkie to part with a couple of them Helium tanks she’s got.


“Mmmm, that’s a nice thought dear. I’d love to consult with you more on the matter but I’m afraid I’m a bit too tired to do so at the moment,” Rarity said, through a yawn. Applejack flashed her a mischievous smile as she walked to the front door as Rarity succumbed to the darkness.
