Gumball, Darwin and Anais walked down the stairs and saw Nicole wearing a pair of tight, black yoga pants and a light blue tank top. "Mom, what are you doing?" Gumball asked.

"Oh hi kids!" Nicole waved. "Good news. The Rainbow Factory likes my rainbow farts, so you don't have to worry about that anymore."

Anais smiled a bit. "Well that's a relief."

"So what are you doing now, Mrs. Mom?" Darwin asked.

Nicole stretched her arms upward, holding a Wii Remote in her right hand. "I've decided to try this new Wii Fit program to help relieve my stress and anger. It's become more popular ever since the female Wii Fit Trainer became a smasher."

"Mom, that's not a program, that's a game." Anais mentioned.

"THAT DOESN'T MATTER!" Nicole yelled, clenching her fists in abrupt rage, causing her kids and Darwin to back away a bit.

"It seems you better start right now." Anais suggested, noticing how irritable her mom was.

Nicole wiped her forehead. "Yeah you're right." she pressed a button on the Wii Remote and started doing some stretches, her big butt in front of her kids and Darwin, sealed underneath her tight yoga pants.

Gumball shut his eyes, using his hands to block what he saw in disgust, being unable to handle the sight of Nicole's sexy ass because of his age. "Mom! Please cover up!"

Nicole groaned in annoyance. "Honey, I am covered up. Please let me do this in peace."

Anais also tried not to look at Nicole's butt while Darwin just stared directly at it, smiling as he felt a mild erection. As Nicole bent down to try to touch her toes, Gumball and Anais gasped as Nicole farted loudly, her butt cheeks vibrating as her jeans felt tighter, with Nicole sighing of relief.

"This feels nice. My farts are starting to fit with my spirit." Nicole stated to herself, bending herself back up and stretching upward, farting loudly again, this time louder than before, and for five seconds.

"OH GOD I THINK I CAN TASTE IT!" Gumball yelled at the smell lingered over to him, clenching his fingers in horror.

Anais plugged her nose with her right hand, picking up the box with the other. "What do you think the Wii Fit Trainer herself does?" she looked at the box, seeing a picture of the Wii Fit Trainer farting while doing a tree pose on it. "I read somewhere online that this is especially beneficial to gassy women who want their farts to be more fit. Still, it seems odd to put a picture of a farting woman on a box."

"Oh I'm sure that box is from Japan." Darwin mentioned, continually staring at Nicole's butt in her tit, yoga pants, which got darker and darker as Nicole continued farting away, feeling relaxed.

Anais took a closer look at the box, surprised to see that all the text was in Japanese. "It is! That makes sense, since Japan sometimes puts out pictures and context that Americans find disturbing or disgusting, or even reference things having to do with violence or torture, and so on."

"I'd love to go to Japan someday." Darwin stated, fully distracted by Nicole's big, gassy butt, which continued farting up a storm as Darwin's erection got stronger.

Nicole did the split pose, stretching her arms upward as another loud poot forced its way out of her butt, causing her black yoga pants to feel even tighter. "This feels great. I feel so relaxed, so fit, and so balanced."

"Yes you do..." Darwin uttered, his pupils fully dialated as he enjoyed watching Nicole's gassy Wii Fit session, feeling fully erected.

"Here we go again..." Anais sighed, still plugging her nose to keep from smelling Nicole's gas as Gumball's face turned green from sickness, causing him to run upstairs.
