Rainbow Dash has to go to the bathroom while running a long race. In both ways. But winning the race means more to her than keeping her shorts dry and clean.

Contains: Wetting and messing. With a bit of farts and soap/washing

This is actually a plausible scenario for her. I've heard people sometimes do this in real life, so for someone like Rainbow Dash it's really not such a stretch.

I know I said I wouldn't write anymore but I'll give this a shot to see if things have changed since I was last here. I doubt it, though.

Rainbow's Wet and Messy Race

Rainbow Will Do Anything To Win

Rainbow Dash was ready to run a big race. This would be her longest racetrack yet to run on. She was not one bit nervous about it, she was very excited. She made a mental note to run on this track with her geode sometime, but she left it at home today because she wanted to win fair and square. She was wearing her usual white T-shirt and her old skintight black shorts. She had drank a big pot of coffee this morning, and also drank lots of water and cider to stay hydrated for this race.

"On your marks... get set... go!"

Rainbow Dash immediately started running as fast as she could. Even without her geode, it wasn't long before she took the lead.

"Go Rainbow Dash!" said Pinkie Pie, for she and the rest of her friends were in the audience.

"Yay," Fluttershy cheered quietly.

Rainbow was able to maintain the lead. She was really enjoying this race so far. The feeling of running fast, the wind in her hair, the long track ahead of her, and so far, she was winning, and she loved winning.

About ten minutes later, she had to go to the bathroom. All her drinks today had gone through her. There were bathrooms on the side of the track, but she decided not to slow herself down by using one of them. Instead she kept running. If anything her desperation made her run even faster.

Another ten minutes later, she really needed to go. She could feel waves of pee sloshing around inside her. So, she decided she would go to the bathroom during this race - but not the traditional way. There had been many other races where she needed to pee mid-race, and rather than slow down and use a bathroom, she would just go in her shorts, or let it flow, as Twilight had said the first time she did it. Many would consider it embarrassing to pee yourself, but Rainbow found it preferable to risking losing the race.

Besides, it did feel kind of nice.

So, Rainbow let go and peed her shorts, which were already soaked with sweat. The pee flowed down her legs as she ran and left a trail of urine behind her. She maintained her speed as she peed, not slowing down even a little.

Fluttershy blushed and giggled quietly at the sight of her girlfriend peeing herself yet again.

"Looks like Rainbow let it flow," said Twilight.

Once Rainbow finished wetting herself, she continued running in her wet shorts, which now not only smelled of sweat, but pee. She didn't mind one bit as long as she won.

About half an hour later, Rainbow reached a sign saying she was halfway done. Only a few seconds after she passed the sign, she let out several dirty wet farts. She chuckled a bit as she ran, for she found farts to be really funny. There was no sound on the TV screen so the audience couldn't hear her.

Soon her farts got wetter and stinkier, and about three minutes after she started farting, she let out a particularly wet fart and felt a bit of poop plop into her shorts. She recognized the signs and realized she was about to have a bad case of diarrhea. Messing herself could be far more unpleasant than wetting herself.

But, she wasn't going to stop running, even to avoid making a mess. If she soiled herself, so be it.

Several wet sharts later, Rainbow reached her limit. She noisily filled her shorts with explosive diarrhea. A big bulge appeared on the seat of her shorts, and some diarrhea ran down her legs.

Everyone in the audience either laughed or exclaimed in disgust.

Fluttershy blushed beet red. "Oh my." She couldn't stop staring at Rainbow's soiled rear.

"I do hope winning the race is worth it," said Rarity. "I could never do... that."

"I'm sure she thinks it's worth it," said Applejack. "She doesn't seem to mind."

Sure enough, Rainbow kept running in her soiled shorts. As with when she peed, she didn't slow down at all. She chuckled a bit at what she had done, and it almost felt kind of fun having messy shorts, kind of like playing in the mud, but stinkier and only on her butt and the back of her legs.

Rainbow kept running, slowing down slightly when she got a bit tired, but staying in the lead, though a few of the other racers were starting to catch up. When the finish line came into view, Rainbow sprinted as hard as she could, and finally crossed the finish line.

"And Rainbow Dash wins!" said the announcer.

Rainbow was panting and dripping in sweat. She walked over to the grass on the side and sat down. She felt the mess in her shorts squish under her tush, but she didn't mind. She drank a large bottle of water and watched as the other racers crossed the finish line. She couldn't tell but she had a feeling some of them had wet their shorts too, but she was the only one with poop in her shorts.

After Rainbow was presented her trophy for first prize, her friends walked up to her.

"You rock," said Fluttershy. "Woohoo."

"Congratulations on winning the race, Rainbow," said Sunset.

"Even if you had to go to the bathroom in your shorts to do it," said Applejack.

"Applejack!" said Rarity.

Rainbow Dash laughed. "It's all right. I don't mind. I do really need to change, though." A sloppy wet fart made its way out of her.

"How about we give her a nice bath at Sweet Apple Acres and then give her some cider?" said Applejack.

Everyone agreed with this, and they got into Twilight's van, with Twilight putting towels and a garbage bag on Rainbow's seat so she didn't get it dirty. They drove with the windows open. Fluttershy sat beside Rainbow Dash, and while she was the only one who could get a whiff of her, she didn't mind it coming from Rainbow.

As they drove, Rainbow wiggled her butt around in her seat, feeling the mess squishing around in her soiled shorts.

When they arrived at Sweet Apple Acres, Applejack rinsed the mess out of Rainbow's shorts with the hose, and then they gave her a bath in a wooden tub, still in her racing outfit, washing her all over. Rainbow really enjoyed this bath.

"Now, let's wash your dirty rear end," said Twilight.

Rainbow smiled and got on all fours with her behind in the air.

"Can I be the one to wash her tushie?" Fluttershy asked with a blush and a smile.

"Go right ahead," said Applejack.

Fluttershy smiled, poured a large dollop of soap onto Rainbow's arse, and rubbed with both hands, coating her stinky shorts in suds. Both Fluttershy and Rainbow really enjoyed this. Once Fluttershy was sure she'd gotten the smell out, she patted Rainbow's butt lightly. "All clean."

After washing her legs and feet, which tickled her, Rainbow got out of the tub and Applejack rinsed her again. Rainbow stayed in her wet outfit until she got home to change. She was not one bit ashamed of using her shorts as a toilet. She won the race, and that made it worth it.
