Fionna's little problem

With heavy breaths coming out of her slowly rising and deflating chest, Fionna slowly mutters some self reassurance to herself before finally sauntering into the main hall of the candy kingdom, right into the largest party of the year in fact. She had gotten an invitation weeks ago but recent events had her having..second thoughts about actually attending it during this time, yet Cake of course wouldn't take no as an answer, quite literally donning her in an azure blue dress and shoving her out the door. It wasn't the dress choice, or significance that nearly every single one of her companions was attending this year, rather in fact, it was her appearance, since despite her humble good looks and personality were in order, her figure was certainly not. In fact, over the past few weeks Fionna soon came to realize that her physique was getting...somewhat chubbier in certain areas, nothing overboard at first but as time went on, she went from flat all over to , well, "voluptuous, curvaceous chub" , with her tummy now muffintopping every single skirt she put on, and her ass threatening to tear most of her clothes due to its substantial increase in girth. As a result, Fionna tries to look as inconspicuous as possible during the party, trying somewhat to keep to the sides and hang out near the punch bowl while others  take to the dance-floor posthaste. It certainly doesn't help her psyche though when she spies a number of smaller candyfolk ogling up her appearance with open-mouthed expressions, just completely taken back by the sheer size of those heft buttocks and doorway-brushing hips, those plump breasts and that chubby midsection all just more to gaze at in amor.

Thankfully for Fionna's sake, she manages to slip through the crowd and end up at the separate refreshments stand on the opposite side of the room, taking solace to herself while enjoying the thunderous cacophony of beats reverberating through the air and partaking in a few of the desserts and making smalltalk with a few of the patrons there. With her mood beginning to change for the best and body feeling more and more comfortable around others, Fionna starts to ready herself for a bit of dancing herself, patting down her dress and making herself look presentable.
That is
Until a gurgling churn at her tummy has her frozen in place while mouthing the words "oh no...not here"
Soon enough she's backed up against the wall with palms at her midsection, pressing against the lacy blue fabric and the influx of adipose at her waist as she blushes a stark red. All that time she had spent on the sidelines drinking and eating finally catching up to her it seems, with her gut rumbling and eyes watering from the sheer idea of doing such an unspeakably obscene act in public, let alone in front of this crowd. Looking away and biting her bottom lip, she 'tests the waters' by clenching her buttocks somewhat to judge how much of an embarrassing predicament she was truly in. Just one flex of her plush posterior is all it takes for her to gulp and feel her mouth run dry in response. She doesn't dare move from that spot either, just a few steps of her thighs rubbing against each other and her buttery soft rearend wobbling would have her unable to contain it any longer. With a glazed look over her eyes and mouth in an uneasy grimace, Fionna resolves herself to her fate and slowly, steadily, begins to widen her stance,  making sure not to do it in a noticeable fashion as her butt is swiftly planted solely against the wall. Gulping once more, and with palms at her waist, she haplessly gives into her destiny.

Within seconds, its begun. Her expression so flustered with beads of sweat appearing about her face, all while she releases her gaseous load right there and then, making sure to keep it at a constant, barely noticeable rate as she feels the humid bouts seep out between her plush asscrack and waft down below. It stays like this way for what appears to be hours to her, time almost standing still as she makes sure to keep it consistently gushing out of her so noiselessly yet in such immeasurable quantities, all while her palms meticulously, tenderly massage and knead against her tubby belly in order to get every pocket slipping out of her fattened bottom. Panting hard and feeling her heart thud against her chest, Fionna can hardly believe herself, she was actually doing it, she was actually farting here in public with no one noticing! Thoughts of hope spark through her mind as she realizes with joy she actually has a chance of getting through this unnoticed. With new hope coursing through her body, she smiles somewhat in happiness at avoiding being deemed "flatulent-prone" by all around her, getting especially comfortable in the process as she grins and slips her palms from her abdoment to her backside, looking as though she was leaning on her hands, when in actuality she's spreading those thick asscheeks as plumes of her own pent-up vapors escape her gaping pucker. Soon enough though after doing this, she realizes with joy that she's holding her asscheeks spread with nothing ebbing from her plush backside. She was victorious.

Breathing an impressive sigh of relief, Fionna stands up and wipes the perspiration from her forehead, overcome with happiness at both getting out of an especially sticky situation, alongside the fact that it..somewhat felt 'good', participating in such a public spectacle of pure depravity. She's quick to saunter to the very center of the dance floor though, both to get a taste of the action, as well as due to how she started to notice others around her sniffing the air..
For the rest of the night, she enjoys herself, dancing with a few princes, getting to know a few newcomers here and there, truly becoming the life of the party with her entire gassy ordeal not at all a hamper on her mindset. By the end of it, she's one of the last guests to leave, looking especially exhausted as she waves goodbye to Gumball upon walking through the doors, somewhat at peace with herself for having such an enjoyable night given the circumstances.
That is, until but a few steps forward later, a massive, gargantuan burst of flatulence sputters free of her juicy ass, blowing her dress up in the air as it erupts out her rump and has her face going completely blank. It comes out with such intensity that both of her asscheeks jiggle and wobble as it slips free of her rear, not to mention how it sounds out so loud and thunderous it even has her entire body shaking from the momentous blast. As she slowly rises her head, expecting the worst, she finds not a single soul in sight, in fact thanks to her all-night partying binge, no one else was around her at all. Not taking the chance to get caught with her dress ruffled up behind her, Fionna takes this opportunity to hightail it out of there, face somewhat reddened but with the biggest smile across her lips at such an unbelievable night such as this. as it slips free of her rear, not to mention how it sounds out so loud and thunderous it even has her entire body shaking from the momentous blast.
