It was high noon in the village of Ponyville and all seemed well. Ponies were preparing for the evening and opening up their shops, mingling and walking around; all seemed well for the time being. Inside one establishment was the frantic clattering of pots and pans of which can only be described as a barrage of clattering, which was coming from inside the compounds of Sugarcube Corner. Inside, the pink party pony with a frizzy mane and tail begun to frantically search for something, seemingly misplaced whatever it was.

“I know it’s around here somewhere...” Mumbled the pink mare, discarding plates and cake pans alike. “Where is it?!” She exclaimed before throwing her hooves up and flopping on her back. “With the Cakes gone for the day on their honeymoon, I have no idea where anything is!” Exclaimed Pinkie Pie, exhaling sharply before throwing her limbs to the side. Perking her ears up, Pinkie noticed something hidden underneath the cabinets. Slowly, she would begin pulling out this cylinder-like object, her eyes going wide once she knew what it was.

Pulling it out and standing it upright, it appeared to be a red container that simply read “Air” on it. “Aha! Here’s that air compressor I need!” She exclaimed before smirking slowly. She looked around a bit then set the air compressor down. Pinkie Pie quickly dashed to the front door and locked the door, closed the blinds and hid herself inside the bakery. She had business to attend to right now, and she could not be interrupted right now. Rushing back to the air compressor, she would examine the hose with a wide smirk, grasping the end of the hose firmly and examined it for a moment, knowing exactly what she would do with it.

The pink party pony slowly turned the nozzle and flipped a switch, of which was previously set to manual, is now set to automatic so she would have little trouble preforming her next actions. Pfssss!! The air pump was now automatically pumping air out, which shot from the hose at a consistent rate. Pinkie then firmly grasped the hose and, without much else, plunged the nozzle between her flanks quickly, wedging the hose’s rubbery tip right up her pink plot. Instantly, Pinkie Pie squealed in delight at first, her flanks begun to inflate, steadily growing from her normal size, slowly they begun to gradually inflate. Pinkie was rather thrilled with the sensation, to which she shrilled out. “Wheeee! This is so much fun! Why didn’t I think of this sooner?!” She exclaimed, her eyes lit up like stars twinkling in the night.

In a matter of moments, her pink plot had grown from her original size, to the likes of two twenty-five-inch overinflated beach balls, her butt cheeks starting to rub against each other. Still, this was not enough for Pinkie Pie and as such, she would turn the nozzle so it would pump air into her butt at twice the speed, prompting a moan from her. “G-getting a little full...but that won’t stop me!” She exclaimed as she felt the air rushing into her more, causing her butt to grow twice as fast. In little time, her flanks reached well over fifty inches, per cheek. Pinkie Pie was completely flabbergasted at what she was witnessing, as she had no idea her bum could get so big. “Woah! My butt sure is big! Much bigger than any party balloon I could make!” She exclaimed with her mouth open in awe, watching her bum get bigger, speed slowing down significantly as her butt begun to get really tight, clenching together and made noises similar to two big balloons rubbing together.

Worry begun to set in as she groaned, the pressure beginning to feel rather uncomfortable, since she was only getting bigger and her butt was getting rather taut to the point where the skin on her butt begun to look shiny. Still, she would wait until she was the size she wanted to be. Thanks to the elixir of a certain zebra friend nearby, she can stretch to limits far beyond normal, so she was not worried at all about permanent damage to herself. Groaning loudly, her flanks had reached a size of sixty-five inches per plot cheek. “J-just a little-Mmff...m-moooore...” she mumbled to herself, her butt now rather shiny and taut. It would seem that the air begun to travel to her tummy, inflating that to about thirty inches.

“Sixty-six...sixty-seven...sixty-eight...s-sixty...n-niiiine...seventy!” She yipped out before grasping the hose and crinked the hose so no more air could enter inside her. Her belly was now a large fifty inches in diameter, with each one of her flanks seventy inches each, making her entire behind a whopping one-hundred-and-forty-four inches wide, counting her belly makes almost two-hundred wide. “I did it! That was so much fun!” She exclaimed happily before switching the pump off.

Failing to see the massive bulge in the hose, she quickly let go of the hose and inflated an additional twenty inches in her belly, making her sweat and groan, her skin now rather tight and sweaty. She would quickly remove the hose and try to walk around. “O-okay...m-minor step-back...” she said with a grin before setting the hose down. Walking around was easy enough, if one can call waddling around the floor and bouncing up and down walking. Soon enough, her stomach started rumbling, indicating that she was feeling hungry, despite her stomach literally being filled to the brim with air. “I better grab a quick bite before having more fun.” She said before bouncing to the fridge and opened it up. There sat an opened can of spherical-shaped pieces of brown food in some sort of sauce. She then shrugged before downing the whole can, can included, letting out a small burp.

Urp!

“Excuse me!” She said before looking down at the shelf, noticing a ripped piece of paper. She picked it up and widened her eyes, instantly figuring out what she just ate. The label read the following. “Farm’s Fresh Baked Beans cooked in Cabbage Juice and sweet sauce, salted to perfection!” Pinkie Pie stares at the label for some time before she discarded it, hoping nothing would happen. Pinkie Pie would somehow crawl into her bed and begun to drift off into sleep, her tail twitching. Just for good measures, she corked her plot up with a spare cork she had in her mane to prevent any mayhem.

Hours passed and Pinkie Pie was fast asleep, her tail twitching as the pressure built quickly inside her over the course of her slumber, growing more buoyant as the natural gases begun to lift her up towards the roof, butt first, somehow crashing through the ceiling. In her slumber, Pinkie Pie’s belly groaned as pressure continued to build, wanting that release it desired. Still, she failed to wake up.

Two more hours had passed, and she finally woke up to the painful sensation in her belly. She looked down and was shocked to find out what she did. Pinkie Pie’s plot had swelled up to the size only previously claimed by parade balloons, slowly shifting over the buildings and would then cast a thick shadow across the lands. Many of Ponyville’s residents had hunkers down in fear for their lives upon viewing the massive twin pink flank-balloons, hearing her belly churn away and stormy bubbles gather inside her butt only seemed to make matters worse. “I-I...gotta find a way out of this mess...” Said Pinkie, the cork in her rear end just barely holding on due to the pressure, as the pressure was becoming too great for her to handle as it was. As such, her frizzy tail wrapped around this cork and gave it a hard pull, quickly yanking it out in an effort to alleviate the discomfort, not quite realizing how big of a mistake that was.

Plop!

"Oooohhhh...I...can feel it coming...” She groaned as her gut gurgled more vigorously. The beans were the catalyst and there was little she could do at this point. She had no choice but to release all the pent-up gas inside, mixed with air and natural gas. There was then one short moment of silent tension before the floodgates give in, sending out a raunchy-sounding noise.

KRACKOOOOOOOOM!!

FRRRRRRRRRRRRPLOOOOOOM!!

A torrent of pure Pinkie methane blasts through town, tearing windows from their hinges and tossing produce like fruit and vegetables from carts with enough forced to propel Pinkie Pie around the town like a deflating weather balloon.

PLRRRRBLBLBLBLRRRROOOOMPH!!!!!!!!

Anypony unfortunate enough to be in the vicinity finds all air replaced by damp, heavy pony fumes that reek of baked rancid compost heaps piled over heaps of concentrated sugar. The unending sound of cheek-clapping fury can be heard all the way from Canterlot in a massive flatulence not seen by anypony for a long time. As Celestia casts a glance over Ponyville from her balcony, she watches it engulfed in a rust-brown mist in complete shock and disbelief. Nothing Twilight Sparkle could not fix.

“I...can’t...stop! Heeeelp!” She exclaimed, to which, of course, she could not be helped at this point. What could really be done, help her deflate faster? She had no choice; she had to get rid of it all. Blowing down small houses, uprooting trees and tearing mailboxes from the ground, she could only just fly around like crazy. “M-my booty is very tooty! W-watch out-!” She exclaimed, blasting through a tool shed and projected herself towards the woods, leaving Ponyville covered in a thick cloud of her stink. In the Everfree Forest, Pinkie Pie got stuck in a tree, farting as hard as she could with enough force to destroy the trees behind her and fling rocks around. She groaned as her belly deflated, only for her butt to only deflate slightly. Over the course many hours, Pinkie Pie had farted so much, deflating down to a manageable level, her butt now a mere twenty inches wide and around her normal size, her skin was now loose and saggy “Oohh...mmhh...that...felt...great! Let’s do that again sometime!” She exclaimed excitedly, letting out a couple of ending toots.

Frrt!

Frrt!

“Hehe! Excuse me!” She said with a cocky smirk. She still had to go home to the chaos of which she created and her stomach still hurt, both the Everfree Forest and Ponyville’s air tainted with her stink thick enough to cut with a blade. Pinkie would worry about that another time, as now it was time to hide for a bit.
