Flannery was in the back of the Lavaridge Town Pokemon gym, trying to place on her tight blue jeans and pooting out muffled toots that were quire embarrassing because she was struggling to get it on. Her Torkoal yawned loudly and woke up alongside her Camerupt who was filling the gym with fire using the fire type attacks that the fiery Pokemon had, slowly turning around to face Flannery.
"Ooh, I had a bit too much hamburgers while I went to Slateport," Flannery groaned and squinted, feeling how painful the tight jeans were since it made her poots more egregious. "Ugh, I wish my stomach wasn't so pudgy!"
As Flannery tried once more to fit the jeans on her butt, she succeeded but released a massive deep pitched brassy fart that echoed throughout the entire gym, with the various gym trainers hearing it as they were all shocked. Flannery's eyes widened for a noticeable red blush appeared on her face, her blue jeans puffed up and darkened with flames as Torkoal dropped his jaw in disbelief with her Camerupt rolling his eyes and heading to the secret room nearby.
"Well... I guess I had to let out some steam eventually..." Flannery laughed nervously for she was embarrassed, zipping up her jeans that made her toot.
However she felt a stomach rumble that caused her to close her eyes shut and bent over and released another deep sounding fart, the flatulent flames spurting out of her brapping butt being strong enough to burn off the back of her tight jeans. Flannery glanced behind her to look at her charred butt, gawking in disbelief as her red panties clad butt cheeks vibrated with another fart, more red and yellow flames spewing out as the low pitched flatulence continued to echo within the gym, much to Flannery's overall embarrassment as all she did was wanting to put on her jeans, not fart flames.
"Dear Arceus!" Flannery remarked while continuing to fart flames that began burning off her panties, eventually leaving her gassy big butt exposed in an embarrassing display. "Maybe I need to lay off the meat for a while!"
The combined smell of rotten brimstone like flatulence and flames was strong enough to knock out Flannery's Torkoal, with Flannery gawking in disbelief upon which she placed her hands on her face, half of her jeans and panties burnt off.
Speaking of the Pokemon God, Arceus was watching this as he would given that he's a divine being, shaking his head at the flatulent redhead.
"Her fuel tank is as explosive as the fire type she represents." Arceus commented with a chuckle as he was eating spicy food while watching to make the heat more intense so he could feel what it would be like to deal with even more hot butt fumes. "Perhaps now it's the best time to change things around here."
And thus without delay Arceus proceeded to do that while Flannery accidentally did her duty of having to doo-doo her work in the literal sense.
