Daisy let out a bassy fart as she panted, fanning the air with her left hand as she could feel how hot it was and smell how bad it could stink. "Woo! I got a load of fart gas in me!"
"Wanna bet that you can beat me?" Toadette laughed as she let out several different farts, ending on a wet one as she laughed while placing her hands on her face in a playful manner. "Ooh, I'm so glad I have extra diapers!"
"...I thought you were wearing pants," Birdo commented as she was blocking out the smell due to her nose... well, being her mouth basically somehow. It's better to not question the way Birdo's body worked, which can be true of most creatures in the Mario World anyway.
"Silly Birdo! Don't you realize that dresses don't match up well with pants?" Peach laughed as she let out several raunchy farts of her own, holding her right leg up with her hand as she stuck her tongue out in delight.
Peach, Daisy, and Toadette all laughed as they continuously farted different farting tones of farts while wearing fart filled jeans, with Birdo groaning as she was the only girl in the elevator who was incapable of being gassy due to her weird bodily functions not matching with the others. Not like she needed to even if she could, as her three girlfriends provided more than enough pooting toots to last a stinky eternity.
"So how much do you think we'll be stuck in here?"
"I hope not for much longer. I can't stand tight spaces..."
"Why not? You didn't have a problem when it came up to certain race courses..."
"Those are different from an elevator. You should know that!"
