>She could feel the helium building up inside her
>Isabelle knew that it would be trouble
>Knew that she should put down her work an get drained
>She couldn't bring herself to do it though
>The Mayor's orchard initiative could bring the municipality 'Perfect Town' status
>That alone made it worth a little discomfort
>Not that it hurt
>On the contrary it felt really good
>She couldn't let that distract her though
>There was a checklist to be completed for each of the new saplings
>Only once they were done would she allow herself some time to vent
>Granted, her growth *was* making it harder to finish the paperwork
>She couldn't get her arms around her breasts or her belly at this point
>Instead she had to reach under her bulging bust, rest the bottom of the clip board on her gut, and then peer over her cleavage to see it
>Frustratingly her view continued to degrade as her tits continued to swell
>Even the growth of her belly lifting the clipboard didn't help much
>At least her blouse and sweater stood firm, keeping pace with her filling figure to protect her modesty
>Not her skirt though
>That was busy riding up her inflating ass, leaving her almost totally exposed
>For the sake of her posterior she'd have to leave forms unfilled
>As she turned to walk away she found her steps uncertain and wobbly
>There was enough lighter than air gas in her to noticeably alter her weight and throw off her gait
>Her hips and thighs were increasingly in on the growing action too
>She could feel the rubbing intensifying as she walked
>Another problem
>That kind of stimulation could adversely affect her by accelerating the helium buildup
>She'd have to hurry if she was...
>Isabelle tripped, landing on her boobs and belly, derailing her train of thought
>She struggled to stand and found she couldn't
>She was beached, unable to find purchase to get up with her arms or legs
>Her clipboard had slipped from her grasp too
>Still had her pen though, as if that would help
>A stray thought crossed her mind, could she puncture herself with the pen and deflate?
>Not worth the chance she decided
>She didn't feel overly full, but there was no reason to risk exploding like that
>Not when she could simply call for help
>Taking a deep breath, she called for the mayor
>Or tried to at least
>Once again the helium in her body conspired to thwart her, raising the pitch of her voice and rendering her unintelligible
>Maybe the pen wasn't such a bad idea after all
>She tried to aim it at her ballooning belly, but met with rather more resistance than expected
>The swelling was creeping down her arms and legs, hindering her range of movement
>Creeping might be putting it mildly
>They were thickening before her very eyes, and her bosoms and belly were still expanding beneath her as well
>She could feel them lifting her as they spread across the grass
>It felt really good
>Snug fabric rubbing against her
>A gentle breeze playing across her
>The sun's rays gently warming her
>Being a blimp like this wasn't so bad

***ALT POP END***

>Part of her wanted more
>With nothing to do but wait for rescue that wish was being granted
>Her pen dropped from her paw, forced from her grips as her digits puffed up like little balloons
>She was starting to round out, engorged limbs slowly sinking in as her body pushed out
>A pleasant fullness spread through her cheeks, and a plumpness through her footpaws
>Not a single creak or groan she noted
>Still plenty of room
>Running short of weight though, as a little gust of wind lifted her
>She swallowed nervously as she failed to descend
>At least she'd be more visible this way
>The ground receded
>No villagers in sight
>She swallowed again
>The view of the town was nice, and the sun was still shining down on her
>Now that she was rising that sun was going to be an issue
>Warm gases expand and rise
>Warm gases inside Isabelle make Isabelle expand and rise
>Rising Isabelle encounters lower atmospheric pressure which makes her expand even further
>Repeat ad nauseam while adding more helium and thus more lift
>She shuddered
>Only one way for that feedback loop to end, and she could already feel it kicking in
>Her limbs continued to sink in, becoming divots of disabled digits in her blimp like body
>Even her head sank in, leaving her bulging cheeks resting upon her body
>The sound of tearing fabric and snapping strands began to issue from her clothes
>Modesty was about to become a casualty
>Would anyone in those little homes below actually see?
>Her skirt replied by blowing its seams and falling away, releasing the tension it had placed on her
>This put additional strain on her panties, which promptly lost their battle for integrity too
>Valiantly her sweater held the line
>It had ridden up on her, containing and restraining her gargantuan chest like a great fuzzy bra
>Isabelle groaned
>Where once her sweater was merely snug, now it was uncomfortably tight
>She could feel it pinning the scraps of her blouse and brassiere against her
>She also new it couldn't hold much longer
>Her ascent was unimpeded and she was still swelling larger and larger
>With a crack the sweater retreated, losing a button and freeing some of her distended body
>Another crack followed as a second button gave and released another outwards surge
>Before a third could sound, it capitulated, tortured fibres succumbing to corporeal integrity failure as her breasts burst through it to freedom
>Isabelle watched the scraps dropped away from her, and felt a smidgeon of satisfaction
>Who has the bigger bust now Cherry?
>It was short lived
>Fullness was beginning to pervade her body, accompanied by the sounds of an overfilled balloon that had thus far been absent
>Pressure welling in up the back of her throat and the few remaining extremities of her spherical body
>A crackling creak from her pelt as it tried to find more give
>She felt it spreading unbidden to sensitive regions, leaving her clit and nipples swollen and throbbing
>Still she rose
>Still growing bigger
>Her head was slowly sinking again, body squishing against her rounded features
>The pressure was becoming a deep breath inside her that she couldn't release, instead pushing her outwards in any direction she could still go
>Thoughts jumbled in her head
>How much larger would she get
>She knew the answer, she could feel the overbearing tightness peaking, the aching of taut hide at it's limit
>Isabelle whined, sharp, almost inaudible
>Finally she burst, the pressure wave pushing back clouds, a roaring blast heard on the ground turning eyes skyward
