Bubbles in Rarity's Tub

"Hey Rarity," said Rainbow Dash. "Applejack and I are doing a Kart race tomorrow. Wanna race us?"

"I suppose that would be rather fun," said Rarity. She at least stood a chance if Rainbow Dash and Applejack weren't going to be running, or in Rainbow Dash's case, flying.

Next day, the ponies arrived at the Kart race and each picked out a Kart. The racing ponies were dressed up for the occasion. Rainbow Dash wore her Equestria Games outfit, consisting of a yellow tank top and skintight white shorts. Applejack wore jeans not unlike the ones Rarity wore in Simple Ways. And Rarity wore sparkling purple skintight shorts, and a matching midriff tank top. She looked absolutely stunning.

"So, Rainbow Dash," came a voice. Rainbow turned to see Lightning Dust, who was wearing a skintight teal outfit. "Ready to lose?"

"Lightning Dust!" said Rainbow Dash. "I didn't know you were gonna be in this race too."

"Well, too bad for you that I am, because I'm gonna kick your butt!"

"Dream on!" said Rainbow Dash.

The ponies drove their Karts to the start line, with Pinkie Pie as the announcer.

"Ready... set... and then go!"

The ponies took off, racing along the road. Rainbow Dash and Lightning Dust were neck in neck, ramming each other. Lightning Dust eventually missed and hit a post on the side of the road, spinning out and falling behind. Rarity got ahead of her before she recovered and drove forward at full speed. They were along the side of a hill now, and Lightning Dust was catching up to Rarity.

"Move aside," said Lightning Dust, and she rammed Rarity, who spun out and began rolling down the hill at breakneck speed.

Rarity squealed as her Kart moved faster and faster off the track. Finally, the Kart hit a rock, sending Rarity flying face first into a mud puddle. In seconds the pigs began tasting her.

...

Near the back of the racetrack, Rarity finished setting up a bubble bath and hopped into the tub. She didn't bother to undress, her outfit was as dirty as she was and she'd prefer it to be cleaner before washing it for real.

She hated the way the race had gone. There was no doubt about that. She hated not being able to finish a race, and she hated getting dirty, but this bath was very relaxing.

Until Rarity felt a gurgling feeling inside her. Was her stomach growling out of hunger? No, this was something else. It seemed that Rarity's breakfast before the race hadn't quite agreed with her.

Rarity looked around to make sure no one was near, and then she farted under the water. Bubbles appeared in the tub around her, accompanied by a smell. Rarity blushed. It was quite unladylike to fart in the tub, but no one was around.

Rarity farted again, more bubbles appearing this time than before, and she couldn't help but sigh of relief.

Why am I farting so much? Rarity thought as she farted a third time, the smell becoming easier to notice. She had never farted so many times at once. There must have been something about those oats.

Suddenly, in a flash, Rainbow Dash appeared. Rarity was startled and accidentally farted in the tub again. Rainbow Dash didn't notice the bubbles at first.

"I won by a landslide!" said Rainbow Dash. "Lightning Dust kept trying to screw me up, but I eventually caused her to crash so hard that she wet herself! She's gonna think twice about messing with me from now-" She noticed the bubbles a split second before they disappeared.

"Um, hi Rainbow Dash," said Rarity, very nervous. "Congratulations on winning the race. Now, maybe you should go and claim your tro-" She was interrupted by more bubbles in the tub as she accidentally farted again, for five seconds. Rarity blushed profusely, and Rainbow Dash fell on her back laughing hard.

"It's not funny, Rainbow Dash!" said Rarity.

"Yes it is," said Rainbow Dash. "Let's see you top this!" She lifted her leg and let out a loud wet fart that lasted seven seconds.

BBBBRRRRAAAAAAAAAAAP!

"Rainbow Dash, that is so-" She paused as she farted again for six seconds. Bigger bubbles appeared around her and this fart smelled worse than the others.

"Like you're one to talk," said Rainbow Dash, and Rarity blushed and hung her head in shame.

"Aw, don't feel ashamed, Rares! Here!" Dashie farted again, for eight seconds this time. She chuckled a bit. "We should totally have a farting contest! I think you'd come close to beating me!"

"I'd never engage in such a vulgar contest," said Rarity. More bubbles appeared around her for nine seconds.

"Such a shame, cause if this were a farting contest, you'd be winning it right now!" said Rainbow, and she couldn't help but laugh.

"That does it," said Rarity. She climbed out of the tub, sparkly clean and soaking wet, turned around so that her rear was facing Rainbow Dash, and farted as loud as possible.

PPPPPPFFFFFFFFFRRRRRT!

Rainbow Dash sniffed. Rarity's fart smelt far worse than any of her own today, but she didn't mind. She thought it was even funnier that Rarity would fart in her face, and started laughing even harder, while Rarity blushed. This was the most unladylike thing she had ever done.

"Well, it's my turn," said Rainbow Dash, and she let out an airy fart that lasted four seconds, looking amused but a little disappointed. "All right Rarity, your turn!" She slapped Rarity's butt with her hoof. Rarity was startled, and without even thinking about it, she farted again. This fart was loud, wet, and lasted five seconds.

"Not the longest fart, but it beat my last one by about one second," said Dashie.

"I don't know why I just did that... I'm going to finish my bath." Rarity jumped back into the tub. The heat was so relaxing.

Rainbow Dash jumped in the tub with her, not bothering to undress. "I need to wash up too."

Rarity wasn't entirely sure about that. Rainbow Dash looked clean to her. But then again, her outfit probably smelled like farts by now. But then why didn't she just take it off? Then, bubbles appeared in the tub around Rainbow Dash. Dashie giggled.

"Rainbow Dash, did you just break wind in the tub?" said Rarity, disgusted.

"Well, you were doing it and I thought it looked fun."

"I do not think it's-" Rarity paused, feeling a really big fart coming. She tried to hold it in. She didn't want to humiliate herself any more.

"Just let it all out," said Rainbow Dash. "You'll feel better in no time!"

"Fine," said Rarity. "But this time is the last time!"

Rarity took a deep breath and farted one last time. The sound could be heard under the water, and bubbles appeared everywhere in the tub. Rainbow Dash's eyes went wide with amazement as Rarity farted for 15 seconds. Rarity blushed beet red, but let out a sigh of immense relief.

"Wow, Rarity! I didn't know you had it in you!" said Rainbow Dash. "Looks like you win the farting contest!"

"We were never having a contest, Rainbow Dash!" said Rarity, still red in the face.

Rainbow Dash sniffed the air. "Phew, Rarity, what did you eat?"

"Just a bowl of oats, at breakfast with you and the rest of the girls," said Rarity. "They've never had THAT effect on me before."

"I bet Pinkie spiked it with fart powder," said Rainbow Dash. "That's one of her favorite pranks. I think she put some in mine, though not as much as yours. I remember she did it to Twilight once, but never Fluttershy. She thinks it's really funny, and so do I." She farted in the tub one last time, to which the bubbles appeared for three seconds.

"Well I don't," said Rarity. She hadn't farted again since the last time, and was sure the effects of the fart powder had worn off.

They climbed out of the tub and made their way to Carousel Boutique.

"Wait till I tell everyone you beat me at a farting contest!" said Rainbow Dash. She usually hated losing, but this was just too funny to her.

"Don't you dare," said Rarity, and she hit Rainbow Dash with her butt, sending her falling into the mud.

"Oh come on I just washed off!" Dashie farted again, and giggled, all frustration forgotten. "But I'll keep quiet about this if you want." She tried to fart again, to no avail.
