>Pinkie giggles as she sticks the hose in her mouth, shivering slightly in anticipation.  
>The entire act seemed incredibly naughty and almost dirty, something she wouldn’t want to get caught doing but was so much fun.  
>The soft rubbery hose squeaks against her teeth lightly as she gives out an almost elated sigh.  
>A pink hoof reaches over to the cool metal nozzle on the cerulean blue tank next to the bed  
>There’s one final hesitation from the giddy pink pony before the hoof nudges the nozzle open, emitting a cold metal creak and the dropping hiss of cool gas flowing down the hose  
>Pinkie’s eyes open up wide as the first shock of air hits her. A rather sweet tasting gas rushes into her mouth and fills up her cheeks till they stretch out like a chipmunk’s.  
>The pony looks over to her mirror at her incredibly silly appearance, her cheeks blown up like balloons, making her giggle and snort a little before continuing on.  
>Pinkie opens up the nozzle a little more, causing her to snicker and snort as she gulps down the gas. It flows down softly into her body, slowly causing it to tighten and feel as if she’d swallowed a balloon.  
>She slowly dropped her free hoof down to her pink tummy as it started to push outwards, slowly filling up with the gas as it rushed into her.  
>Pinkie blinked and gave out the occasional giggle, the gas tingling every part of her body, making her feel even more excited as her belly and chest blew up like a pink beachball.  
>Her legs were pushed apart to make room for her swelling belly while her butt began to take on gas.  
>The party pony giggled and blushed as she felt her pink pony rump slowly swell with gas and lift her up from the bed, becoming a nice soft squishy seat under her and prompting her to bounce and rock on it playfully  
>Soon her four hooves began to swell up, each one quivering a little and jumping with a shock of gas, followed by the slow, hissing swelling. Each hoof became soft and bouncy to the touch like big inflatables.
 
>A barrage of different emotions and feelings began to fill the puffy pink pony as fast as the gas  
>Feelings of excitement, embarrassment, naughtiness, anticipation, nervousness, lust, and pleasure.  
>All while the hissing gas tickled and teased pinkie all over.  
>Her inflating pink form began to take on an almost rubber feel, becoming glossy like vinyl and incredibly squeaky  
>The pony giggled and laughed behind the hose as she tried to move around, waddling on her puffy hooves barely able to touch the ground, wiggling and bouncing her enormous balloon butt, making herself squeak and squirk loudly  
>The swelling pink balloon rolled back on her enormous rump, blushing deeply as she started to feel even more excited from the entire experience, loving the feeling of being a big, bloated pink pony balloon!  
>She rocked forward a few times, grinding into her bed lightly, emitting a creaking squeak with each motion and tickling her in just the right places.  
>Pinkie gasped and moaned lightly through the hose, closing her eyes softly  
>She squished her puffy hooves into her balloon of a belly, squeaking and bouncing against the bed, grinding rhythmically against the covers  
>The friction of the soft cloth tickled her sensitive rubbery skin as it slid against it with each push, making the pink pony go faster  
>The gas rushed in, the pony stretched and swelled, becoming puffy and bloated all over, filling up to be bigger then her bed!  
>Pinkie moaned and giggled, panting behind the hose as she gulped down more and more air like a hungry balloon
 
>Her ears puffed up, her nose swelling to become cute and squishy, her hooves starting to pull in, keeping her from moving them.  
>Even her tail swelled up and bounced behind her with each push and pump against the bed  
>The feeling was overwhelming, pinkie fluttered her eyes with anticipation, giving out even squeakier gasps and moans, whimpering a little as she began to lose herself in the pleasure of being a big blowup pony  
>She pumped and bounced, squeaked and moaned until gasping through her puffy nose and clenching her eyes shut, tensing up as she was pushed over the edge!
 
 
>Her tightened body began to loosen up as Pinkie gave out the occasional quick gasp of air, letting the hose drop out from between her teeth  
>She grinned and closed her eyes before bursting out laughing  
>The blowup pink pony giggled and snorted to herself, bouncing on her huge butt  
>She leaned back and sighed, looking up at the ceiling and losing herself in her thoughts for a bit.  
>Pinkie’s puffy ears suddenly perked up with a squeak as she gasped, an idea obviously filling her head  
“Oohh I can’t WAIT to show the girls this!”
