Author's Notes:

Requested as a sort of experiment, and not likely to be the longest.

She will be wearing her regular outfit of a blue shirt and purple skirt. With purple panties underneath

Trixie was putting on another one of her magic shows on her stage before an audience. Sunset Shimmer was helping her with it.

After Trixie finished one magic trick, her stomach growled and she groaned in discomfort. Her breakfast today didn't seem to settle well with her.

"Trixie, are you all right?" said Sunset, looking a bit concerned.

"Trixie is quite all right," said Trixie, and she retrieved a deck of cards for her next trick. "Now, witness the next spectacular trick of the Great and Powerful-"

PPPPPFFFFFFFT!

Trixie blushed beet red while the audience laughed. Sunset chuckled a bit.

Once the laughter settled down, Trixie regained her composure and started doing the card trick, but in the middle of shuffling the cards, she let out another loud, wet fart, which was longer than the first. The audience laughed again.

"Phew, what did you eat?" said Sunset.

"A breakfast that was..." FFFFRRRRRT! "most certainly undercooked." PPPRRRRRT! "I washed it down with some prune juice."

"Sometimes when I fart like that, it means-"

"The Great and Powerful Trixie knows what it can sometimes mean." She farted again. "But I can hold it for the rest of the show."

"I hope so."

She did her card trick, and then moved a box onstage.

"Now, the Great and Powerful Trixie is going to saw Sunset Shimmer in half!"

Sunset got into the box, and Trixie turned it so what appeared to be Sunset's feet were sticking out of the other side. Trixie bent over to start sawing, and as she did, she let out another fart, louder and wetter than the last.

As she moved the two boxes apart, she farted again, and felt a bit of poop slide into her underwear.

"Uh-oh! The Great and Powerful Trixie has to go!"

She ran off the stage as fast as she could. Sunset got out of the box and followed her.

Trixie ran towards her house. Though it wasn't that far from the stage, she could feel the pressure increasing the closer she got.

She let out several more wet farts along the way, one or two of which might have been more than a fart.

Once inside her house, she raced to her bathroom. As she got closer to the toilet, she could feel it coming out uncontrollably. She reached the toilet, pulled her soiled panties down, and sighed in relief as her bowels emptied into the toilet with a loud splash.

Once she was done, she dumped what was in her panties into the toilet, pulled them back up, and flushed. She didn't bother wiping herself because her panties were already dirty. She needed to shower.

As she was getting a spare skirt and pair of panties to change into after her shower, her doorbell rang, and she looked through the hole. Seeing it was Sunset, she opened it.

"Hi Trixie. Did you make it?"

"Mostly. I regret to say that the Great and Powerful Trixie might have made a bit of a mess in her panties."

"I'm so sorry. If it's any consolation, I've soiled myself before too. Would you like me to give you a bath?"

"Actually, Trixie would like that very much."

They walked into the bathroom, and Sunset started to fill the tub with water. All the running water made Trixie need to pee. Sunset already knew she soiled herself, and her panties were already really dirty, so what she decided to do next couldn't hurt.

Trixie sat on the toilet and peed in her dress. She sighed in relief as she felt the warm wetness soak her underwear. Her stream passed through the back of her skirt and into the toilet below.

After she was done peeing, Sunset finished the bath. Trixie stepped into the tub and sat down, submerging her wet skirt and soiled panties. Sunset poured a bucket of water over her hair and started to lather it with shampoo.
