Flannery was in the back of the Lavaridge Town Pokemon gym, trying to place on her tight blue jeans as she was struggling to get it on. Her Torkoal yawned loudly as he woke up, slowly turning around to face Flannery.
"Ooh, I had a bit too much hamburgers while I went to Slateport," Flannery groaned as she squinted, feeling how painful the tight jeans were. "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 as a noticeable red blush appeared on her face, her blue jeans puffed up and darkened with flames as Torkoal dropped his jaw in disbelief.
"Well... I guess I had to let out some steam eventually..." Flannery laughed nervously as she was embarrassed, zipping up her jeans.
However, she felt a stomach rumble as her eyes widened, closing her eyes shut as she bent over and released another deep pitched fart, the flatulent flames spurting out of her 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 as she continued farting flames that began burning off her panties, eventually leaving her gassy big butt exposed. "Maybe I need to lay off the meat for a while!"
The combined smell of rotten flatulence and flames was strong enough to knock out Flannery's Torkoal, with Flannery gawking as 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.
