In the middle of the afternoon, the town known as Ponyville seemed relatively calm and mellow, whereas the Apple farm was busy working hard, Fluttershy's cottage was sound and all else seemed calm, even Rarity's boutique, to the fancy mare's displeasure.

"Oh dear me... we haven't had a single customer in ages! Whatever shall we do in such disarray?" Squealed the white unicorn from inside, where she laid upon her red Drama Couch in her usual exaggerated dramatic pose, with the back of her hood to her forehead and her hair flipped back. Opalescence slowly walked into the area and let out a demanding grumble, which could be associated with hunger. Rarity, being busy with her pouting, hardly paid any proper attention.

Opalescence screeched a bit, still to no response. "Oh why must it be so dull around here? Oh what I wouldn't do for something new to try out!" Opalescence hissed loudly, then walked off from being ignored and curled up somewhere while playing with a ball of yarn.

Then it hit Rarity. The white, bedazzling mare sat up in her chair and looked around, rubbing her chin in thought. She could remember a specific incident involving a scenario of Spike and Applejack a little while ago, where Applejack saved Spike's life and Spike had his dragon code to live by and preformed tasks for her until the debt is returned. Rarity could recall Spike doing a few spontaneous acts for her when she didn't have anything for him to do.

Rarity remembered that Applejack told her and her friends about the fact that a spike felt it was necessary to help Applejack breathe by puffing and inflating her up with a pair of fireplace bellows that he rapidly rushed air into her in an attempt to assist her in breathing, only for her to blow it all back out again and say that she didn't need help breathing.

Rarity rubbed her chin in thought, then stood up from her seat and begun towards the kitchen, deeply intrigued by her own thoughts that rushed in and brought a smirk to her muzzle. Dashing into one of the big cabinets, she begun to rummage through her things, spilling crafting materials and gemstones on the ground in the process.

A few moments had passed, and she squealed in delight. "Aha! Here it is!" The fancy unicorn said with a cheeky smirk that said, 'mischevious'. Using her magic she slowly drew the curtains inwards, and draped the blinds down to shield any view from the outside, while flipping her 'open sign' to a 'closed sign', closed the door to the boutique and locked the door to make sure no visitors were to come in.

A giggle escaped her vocals as she slowly dragged something big with a bit of effort, even with magic it was hard to pull such a weight. From under the cloth, she unvealed a large air compressor that sat there, with an on-off switch on the side, and grey in color. Rarity hummed to herself, and made sure every door was locked before proceeding.

Rarity grabbed the hose and examined the nozzle. It looked soft, and pointy though it looked relatively safe to what she was going to do. "Oh...I really shouldn't...but I can't help myself!" The white unicorn said, before placing the tube into her mouth, and used her magic to start the machine.

Instantly her cheeks begun puffing up,and begin traveling down her throat hole. Humming in thought and delight, her abdomen begun to fill up with this air, making her belly look like she's a little chubby. "Mmmmmm...i-it feels..." Rarity squealed out, attempting to nerf it a bit with her magic, though was lost in her own thought, which caused her magic to misfire and do the oposite.

"Mmmm!" Squealed out the white unicorn, as quickly air rushed into her body faster at double the speed, causing her midsection to quickly widen and expand out rapidly, already making it look like she swallowed a beach ball and begun puffing out her petite flanks wider and wider.

"Th-this is...Mmff...This is so unladylike of me, but I can’t get rid of that image of Spikey Wikey Inflating dear Applejack. Those puffy cheeks, those helpless legs, how round and big she got, gulping all of that air. This is so divine!" Rarity exclaimed between bursts of air that shot down her throat and into her ever inflating midsection. Already her hooves begun to lift up off the ground and she became more buoyant, all the while her growing petite plot cheeks grew so massive in a matter of moments.

The mare's belly, and her flanks, had to have reached around 40 inches in width, with her two white, diamond-cladded flanks bobbing up and down as she bounced up and down in the air. Rarity squealed in protest, as this was becoming a little much for her, so she attempted to turn it off, but in doing so she accidentally set it to automatically gradually blow more air out faster. She squealed and flailed her little hooves around, in futile attempts to stop the machine for now.

"Mmmm!" Rarity yelped out, unable to speak anymore as the tube took up much space at this point. She tried again to reach for the compressor, but the way her stumpy hooves inflated rapidly, and sunk into her body, made this impossible as her legs now resembled little nubs around her body. This turned from enjoyable to just torture as she wasn't sure how long her body could sustain this sort of thing, as at this point, as time went on, she went from 40 around 80 inches in diameter, bouncing up and down, stuck prisoner to her compressor until her body just couldn't take it anymore, or the machine decides to let her go.

Rarity let out a subtle groan, her eyes half-lidding as her body became more taut, her white flanks squeaking with every little movement, rubbing against each other and made a sound similar to what balloons make when they're rubbed together. The air compressor only kept pumping out more, and more air, filling up her puffy body and forcing her skin to tighten and her body to become shiny and squeaky. Until she heard a groan from inside of her.

The unicorn's eyes widened as she groaned in protest, her body rumbling slightly. "Mmff? MMFF!" Rarity protested, trying to free herself before it became too much for her body to handle, in more ways than one. Her body only filled with more air, increasing her size and increasing that grumble inside of her. She tried her hardest to hold back this urge that she was having, forcing the air to subside inside of her, and the pressure only to build up inside. Rarity squealed, almost whining, nearly crying as she mentally begged her body not to give in in which it eventually would, though she preferred on her own time in somewhere more private.

Rarity's stomach groaned, and grew in protest, wanting that release it so desired. Rarity could only clench her flanks as tight as she could, causing those two white, marzipan globes to bobble and rumble rapidly, even her tail tucked between her cheeks to prevent any air whatsoever from escaping. Little did she know, the air pump kicked it into high gear by itself, pumping out air ten times faster.

At this point, the mare went from 80, to 120 inches in diameter, bobbing and squeaking as her skin became rather tight and shiny, and somewhat transparent.Rarity had very little choice but to either hold it in, or release it all at once. She wasn't about to do the latter willingly, so she tried her very best to hold it in as hard as she could, to hard infact that her plot begun sweating, as well as her whole entire body. "Mmmmffff! Plsh dmph cugh ough!" Which would translate to, 'Please don't come out!' Of course, the machine didn't listen, and kept pumping.

Several thoughts raced through her mind,such as, "Oh, for the love of Celestia and Luna, pleaaaase don't do that!" Of course, the pleads were in vein as her flanks continued growing rapidly, meanwhile her tummy almost screamed, groaning, churning, and gurgling in discomfort, wanting to release. Rarity heard a little noise, the sound of a cat meowing.

"Ophlescenphe?! Sh-shwo!" Rarity tried to shoo her pet away, trying to reason with it, whom wanted food, and wasn't going to take no for an answer. Of course, it was hard to see her anyways, seeing as she was right behind the growing, unstable blimp of a mare. Her skin now begun to hurt, as her flanks squeaked, becoming unstably big, easily filling up the room. Opalescence, of course, was right behind her. Rarity tried to shoo her away with her nubby hooves frantically, trying to get her out of harm's way.

The cat just wasn't budging, and the elegent mare was mere moments away from said budging. Her skin was transparent and seethrough. She had no choice, otherwise she'd blow, in more ways than one. Rarity just couldn't hold it anymore, as much as she didn't want to release all that pent up pressure out her rear it had to be done. With that, the mare shut her eyes.

The white unicorn groaned, as she lifted up her curly tail instinctively, letting out a few light hisses of her built up gas. Opalescence looked up at the two massive globes of what was her owner in shock,and begun to back up, hissing loudly. It was far too late, and it couldn't run fast enough. Suddenly, a few small toots escaped her rear in short bursts, a few puffs of her wind came out. Rarity's cheeks were beet red. She had to do it, and now.

With one final grunt, Rarity's rear begun to enormously erupt in a gargantuan explosion of toxic gas that begun to violently rush out of her backside in one huge fart that quickly propelled her forward, making her faceplant into a nearby wall, and instantly blowing her pet cat away and against the wall with the full force of her explosive wind breaking.

FFFFLLLLRRRRPPPPRRRRRRRRRMMMMMMFFFFBPTTTT!!!!!!

Rarity squealed out, as her body begun to gradually shrink with the rapid deflation that both pinned her poor pet to the wall and polluted the whole room. With the force of her rump, the hose dislodged itself, making her deflate from both ends at once, her mouth in the form of one large belch, and from her rump in the form of one long fart, in which this would go on for quite some time, forcing her to spin around the room like crazy.

UUUUUUUUURP!!!!

AUUUUUUCK!!!!

BLRRRROOOUUURRRAAAAPF!!!!


After two hours of pure deflation, Rarity's body finally begun sputtering to a halt, and with one final push, she finally pushed out the remaining of the gas that was boxed into just her boutique and tainted the air so thick one couldn't even breathe in there, or hardly so. Once things had settled, Rarity flopped to the ground and almost passed out, panting heavily.

"Oohh...W-well...th-thankfully nopony got hurt..." Rarity said, hardly noticing a traumatized white cat besides her, her fur was all puffed out and frizzy. "L-let's get some air in here..." Said Rarity, opening up the windows and letting the smell pour out into the town, the stale air expelling out and begun polluting Ponyville...to which the town folks were not very fond of. The mare would worry about that later. For now, she needed rest.
