Author's Notes:

This chapter contains a bath scene. Yes, soap/washing lovers, two chapters in a row!

"I win!" said Rainbow Dash as she crossed the finish line on a hot summer day.

Applejack crossed moments after, as exhausted and sweaty as Rainbow Dash was, but having had fun all the same.

"Good game, Rainbow," she said as she shook her hand.

Sunset Shimmer watched from the sidelines, enjoying the show. Rainbow Dash began wringing the sweat out of her hair.

Just then, a girl walked up to them. She was a similar shade of blue to Rainbow Dash, with fairly short orange hair. She was wearing a teal pair of short skintight shorts, and a matching midriff tank top.

"The great Rainbow Dash," said Lightning Dust. "I've always wanted to race you and prove I'm faster! The name's Lightning Dust."

She walked closer to Rainbow Dash, took one whiff, and recoiled.

"Ugh! You smell awful! Did you soil yourself or fall into a pile of manure?"

"Neither. I just don't wash much."

"Well, all right." She backed away, but got closer to Applejack and sniffed her. "Ugh, you smell almost as bad as her!"

"And I'm proud of it," said Applejack, wiping sweat from her forehead. "Wait till you smell Indigo Zap."

"I'd rather not! I'll just race Rainbow Dash!"

"You're on!" said Rainbow Dash.

They stood at the start line while Applejack and Sunset stood to the side.

"Ready... set... go!" said Sunset.

Rainbow Dash and Lightning Dust ran as fast as they could. They were neck in neck, occasionally one of them pulling ahead.

"Rainbow's gotta be plum tuckered from our race," said Applejack.

"She can do it," said Sunset.

Rainbow was slightly ahead of Lightning when they crossed the finish line.

"Rainbow Dash wins!" said Sunset.

Rainbow and Lightning were panting, dripping with sweat.

"Good game," said Rainbow Dash, holding her hand out for Lightning Dust to shake.

Lightning slapped her hand away. "I don't shake hands with smelly girls! I'll never get over the shame of losing to one!"

"Hey, lighten up," said Rainbow Dash. "Just have fun with the sports."

"I'll have fun beating you up!" Lightning Dust ran at Rainbow Dash, tackling her backward into Applejack and Sunset. All four of them fell into an empty trunk, which had been dumped at the side of the track. The door to the chest closed, and its flap fell down so that it could not be opened from the inside.

The four girls barely fit inside it. They were awkwardly positioned so that Rainbow Dash's butt was pressed against Lightning Dust's face, and Sunset's butt was pressed against Applejack's face. They tried to open the trunk, but it wouldn't open. Someone would have to open it from the outside.

"Get me out of here!" said Lightning Dust. "Or at LEAST get your stinky ass out of my face! I can't stand your smell!"

"I can't get out of this position!" said Rainbow Dash. "Trust me, I don't like having your face on my butt any more than you do!"

"Ah can't believe this is happenin' again," said Applejack, remembering her dare at the slumber party. Sunset had been gassy earlier this morning so her jeans smelled like farts, but Applejack did like the feeling of Sunset's butt.

An hour went by, and still no one opened the trunk. The inside of the trunk smelled REALLY bad now, with Rainbow Dash and Applejack stinking it up. Lightning Dust didn't know how much longer she could take this. Plus, she needed to go to the bathroom now, as did Applejack.

"Uh-oh," said Sunset.

"What?" said Applejack.

"It's happening again..."

"What is?" said Lightning Dust nervously.

BBBBBBBRRRRRRRRRRRRRRRRT!

Sunset sighed as she farted loudly in Applejack's face.

"Phew, Sunset," said Applejack.

"Excuse me..." Sunset blushed lightly.

"Ugh, that's disgusting!" said Lightning Dust.

"She's not the only one..." said Rainbow Dash.

FFFFFFFFFFFFFRRRRRRRRRRRRRRRT!

Rainbow Dash chuckled as she farted in Lightning Dust's face.

Lightning Dust struggled as best she could, trying to thrash around. "GET ME OUT OF HERE!"

PPPPPPPFFFFT! BRRRRRT! PPBBBRRRT!

Rainbow let out a few more boisterous wet farts while Sunset did her best to hold it in. Lightning Dust felt nauseated, and her shorts grew warm and wet.

The sound of Lightning Dust peeing made Applejack leak a little, and when Sunset accidentally released another explosive fart, Applejack lost control and started to pee full force in her dirty, smelly jean shorts. She couldn't help but sigh in relief as the sound of her peeing drowned out that of Lightning Dust.

"Whatever you do, DON'T soil yourself!" said Lightning Dust.

"No, it's just farts," said Rainbow Dash. "I don't even have to pee right now."

Rainbow and Sunset farted for another half hour straight. The inside of the trunk smelt so bad that Lightning Dust fainted twenty minutes before the farting stopped.

Lightning Dust woke up a few minutes later. She took one whiff of the smell of sweat, farts, and urine, and passed out again.

Just a little over half an hour later, the trunk finally opened. Twilight Sparkle stood over them. She held her nose as a foul smell came rushing out of the trunk.

"Thanks, Twilight," said Rainbow Dash as she and Sunset climbed out first.

"Any time," said Twilight, fanning the air with her hand. "I noticed movement in the trunk, so I knew someone must be locked in."

Applejack climbed out, and Twilight saw her wet shorts. "Are you all right, Applejack?"

"I'm fine. I'll just rinse off in the shower."

Twilight saw Lightning Dust sitting unconscious in her own puddle. "Poor girl, locked in there with your smell. Is she..."

"No, but she's out cold," said Sunset. "She's the one who locked us all in there, because she was a poor sport when she lost a race to Rainbow Dash."

"I know just what to do with her," said Rainbow Dash.

...

Lightning Dust woke up. She was being carried by Rainbow Dash and Applejack toward Applejack's house. She smelled of farts, and her shorts were drenched in pee.

"Let me go! What are you doing?"

"You need a bath, girl," said Applejack.

"Excuse me! You and Rainbow Dash are the ones who need baths!"

"True. But we like smellin' bad, and I'm sure you don't."

"Besides, you shorts at least need to be washed." Rainbow Dash chuckled, and Lightning Dust blushed.

They reached Applejack's house, and Applejack started to fill a round wooden tub with soapy water.

"I can do that myself!" Lightning Dust started to run, but Rainbow Dash ran after her and got her to the ground. She sat on her butt and, feeling gassy again, let out another loud fart. Lightning Dust groaned.

Once the tub was full, Rainbow Dash stood up, and she and Applejack picked up Lightning Dust. Lightning Dust struggled against them, but they threw her into the tub.

"Hey, you're getting me all wet!" Lightning Dust complained.

"You were ALREADY wet," said Rainbow Dash.

"I don't wanna take a bath!" Lightning Dust splashed around.

"We gotta get that fart smell out," said Applejack.

Lightning Dust sniffed. "You smell even worse than I do."

"Ah don't mind." Applejack let out a deep-pitched fart and chuckled.

Rainbow Dash and Applejack started scrubbing Lightning Dust's sides and armpits. Twilight put a dollop of shampoo on her hands and started lathering Lightning Dust's hair. Lightning Dust raised her feet out of the tub to kick in protest, but Sunset grabbed both of her feet and started to scrub her legs.

Lightning Dust had never felt more humiliated in her life. She had been farted on by the smelliest girl she had ever met, she had wet herself like a baby, and now she was getting a bath from two smelly girls, an extremely flatulent girl, and a nerd.

Once Sunset was done scrubbing Lightning Dust's legs, she started to scrub her feet. Lightning Dust was extremely ticklish, and she splashed around laughing, emptying half the tub and soaking all four girls.

"Thanks," said Applejack. "Ah don't have to shower now."

Lightning Dust sniffed her. "Yes, you still do." She sniffed Rainbow Dash. "You don't smell any better than before!"

"Good," said Rainbow Dash.

Rainbow and Applejack held Lightning in place, Sunset continued to scrub her feet while she squirmed, and Twilight got the hose and filled the tub with more hot water.

As Lightning Dust laughed harder, bubbles appeared in the tub around her. She blushed a little.

"There's no shame in farting in the tub," said Rainbow. "I do it just about every time I get a bath!"

"Since when do you take baths?" said Lightning Dust.

"Time to wash yer dirty rump," said Applejack.

The four girls set Lightning Dust into a position so her rear end was in the air, and they began scrubbing it at once, engulfing it in suds. Lightning Dust got her head and arms out of the water, hanging them over the side of the tub and feeling more embarrassed. She accidentally let out another wet fart, causing the girls to scrub harder.

Finally, they finished, and, after Rainbow Dash patted her butt lightly, they sat her down in the tub. Applejack and Sunset poured buckets of warm water over her for a final rinse.

"There, all done," said Applejack.

Lightning Dust stood up and stepped out of the tub. She was soaking wet and sparkling clean.

"Thanks, I guess?" said Lightning Dust. "That was awful, but at least I don't smell like farts anymore, and no one can tell I wet my shorts."

"So, no hard feelings about me smelling bad or farting on you?" Rainbow Dash held out her hand.

"Don't get too mushy with me. I will win next time."

"You know who would be good practice for your next race? Look for a girl named Indigo Zap. Sometimes she runs at that racetrack too."

"I will! Enjoy your ass-kicking the next time we meet!" Lightning Dust ran off.
