Princess Peach and Bianca were both sitting at a campfire on logs, with both of the girls wearing jean shorts as they were eating beans together, with it being nighttime. Peach's shorts were pink, while Bianca's shorts were white.
"Mmm, I do love these baked beans!" Peach admitted as she lifted her legs, letting out a trombone like fart as she sighed of relief. "It's too bad Waluigi isn't at his taco stand to give me tacos on account that it's his birthday, but that's okay! Beans are the bomb!"
"Tell me about it! The way they make you let loose those soothing, brassy tunes..." Bianca stated as she bent over, letting loose a high pitched squeaky fart that immediately got deeper pitched as she sighed of relief, smiling and opening her eyes. "It's just empowering!"
Peach smirked as she then bumped butts with Bianca. "I bet I can accidentally poop myself more than you." She boasted as she raised her right butt cheek, letting out several small but brassy toots that puffed up the back of her shorts, giggling as each got more tuba like.
"You're on, Pootstool!" Bianca responded as she released a poot so brassy it turned the entire back of her shorts brown.
And thus, the two blonde humans girls tried to outfart each other, their brassy flatulence echoing throughout the forest, much to the Pokemon living nearby. One thing was certain, both were going to need new underwear.
