"Oh Iris!" Cilan shouted, with him, Iris, and Ash Ketchum in a random route somewhere in the Unova region... most likely by the Pokemon League because why not.
"What is it now, Cilan?" Iris sighed as she had her arms folded. "I'm not in the mood for stupidity..."
"...but I bet you'll want this!" Cilan exclaimed as he then revealed a pair of white tight jeans. "Isn't it just... incredible?"
Iris stared blankly at Cilan. "Don't know what's incredible about pants."
"Oh try it on. Trust me." Cilan stated with a creepy smile.
"If it'll make you not as annoying..." Iris mumbled as she swapped out her regular white pants for the white jeans, struggling to put them on. "How the hell do you expect anyone to fit in these damn-" She finally got the jeans on, pulling them up. What she didn't expect, or want for that matter, was that she felt her butt balloon to be bigger than normal, burping out a bassy fart. "...Cilan, where did you get these fucking jeans from!?"
Cilan chuckled as he twirled around. "Oh, I made them myself. Used plenty of fine ingredients in my cooking to cook up a splendid-"
"You... MADE THESE OUT OF FOOD!?" Iris exclaimed angrily as she punched Cilan in the face, glancing back at her farting big butt in dismay as she clenched her fists. "Argh, no wonder I suddenly felt gassy! It's another one of those stupid fart fetish fanfics!"
"Jeans making a girl fart... where have I seen this before...?" Ash mused to himself as he rubbed his chin, eating a bouquet of food along with his other Pokemon.
Pikachu just shrugged as Axew had a panic, not knowing what to do since he has never seen or heard Iris fart up a storm of flatulence before. Not like this.
