Author's Notes:

They're still wearing their usual outfits. Always unless otherwise specified.

It was spring, and the girls were now in their early twenties. They still looked and dressed the same as when they were 18 or 19, and nothing had really changed with them. They still retained their unusual quirks.

Rainbow Dash and Cherry Fizzy were getting married at the park. Among the guests were Rarity, Pinkie Pie, Fluttershy, Applejack, Sunset Shimmer, Twilight Sparkle, Wallflower Blush, Sonata Dusk, Aria Blaze, Adagio Dazzle, Indigo Zap, Lightning Dust, Sunny Flare, and Flash Sentry. Indigo sat a bit away from everyone else.

"Here is your wedding dress," said Rarity, handing a beautiful white dress to Rainbow Dash.

Rainbow Dash put it on over her usual smelly outfit. "How do I look?"

"You look lovely." Rarity sniffed her a little. "You smell quite the opposite, of course."

Rainbow chuckled. "Hey Rares, can I get this dress dirty?"

"I would prefer for a beautiful dress to stay clean. But, it's your dress, so if you want to play around in manure, knock yourself out."

"I wouldn't go THAT far, but thanks Rarity!" Rainbow was excited about what would come after the wedding.

Rainbow Dash and Cherry Fizzy, who was wearing a tuxedo, walked up to the altar while Fluttershy had some birds sing a song. Mayor Mare pronounced them husband and wife and they kissed.

"Now it's time for the party!" said Pinkie Pie.

Vinyl Scratch put on a rock song, while Rainbow Dash and Cherry sat at the table next to the others.

"Rainbow Dash, this cake is for you," said Pinkie Pie, setting a chocolate cake in front of her.

"What's wrong with the wedding cake?" said Rainbow Dash.

"It doesn't have a secret ingredient. This cake does!"

Rainbow suspected she knew what the secret ingredient was, and chuckled.

"I hope she eats it soon," said Pinkie Pie, sitting back down next to Sonata. "I held it in all day waiting for her to fart!"

"Me too," said Sonata, fidgeting in her seat. "I don't wanna have an accident BEFORE we start laughing at her farts!"

"I know, right? It would just ruin this running gag!" Pinkie crossed her legs tight, desperately trying to keep her jean shorts dry until it was time.

"I don't know, the audience is probably getting tired of us wetting ourselves every single time someone farts."

"Here's two six packs of my finest cider," said Applejack, setting them on the table.

"Thanks," said Rainbow Dash. She turned toward Cherry. "Do you want any?"

"No, I'll drink the punch. You go ahead and drink all of them."

Rainbow ate her cake messily and noisily, getting bits of chocolate frosting on her dress. Rarity winced slightly, but also giggled a bit. This was the Rainbow Dash she had always known, and while she didn't really like how dirty and messy she was, she was used to it and could put up with it forever.

Once Rainbow finished the cake, she downed each cider as fast as she could, spilling a little down her front for the second pack of cider.

"Ahhhh," sighed Rainbow Dash. BUUUUUUUUUUURP! "That tasted awesome!"

"The cake or the cider?" said Applejack.

"Both!"

It wasn't long before the fart powder Pinkie had put in the cake and its frosting began to take effect. Rainbow grinned as she felt that familiar feeling.

PPPPPPPPPFFFFFFFRRRRRRRT!

Pinkie and Sonata burst out laughing and wet themselves.

"Rainbow Dash, how dare you befoul my beautiful dress?" said Rarity.

"But you said-" Rainbow began.

Rarity winked, and Rainbow Dash understood. Rarity was only acting offended to keep up her ladylike image. Rainbow winked back, and farted again.

PPPPPRRRRRRRT! BBBLLLRRRRT! BBBBRRRRRRT!

Cherry chuckled with each of Rainbow's explosive wet farts.

"Nice one, Rainbow Dash," he said after a particularly loud and wet fart. "Uh, are you all right?"

Rainbow felt her butt. "Yeah. I didn't make a mess this time."

"Too bad I'm not gassy right now," said Sunset. "We could have a farting contest."

Rainbow Dash kept farting for a half hour before her gas was gone, much to her disappointment.

"It was fun while it lasted," said Cherry.

Rainbow nodded, and then felt a sudden urge to pee, for all the cider she drank had gone through her.

"I gotta go to the bathroom." She stood up and ran toward the outhouse.

"Rainbow, wait!" said Cherry, walking behind her.

Rainbow turned around, holding herself and fidgeting slightly. "Yes?"

"I have something to tell you first," said Cherry.

"Make it quick! I really need to go!"

Cherry leaned in as if to whisper something in her ear... and then he started to tickle her smelly armpits.

Rainbow Dash started to laugh hard. She didn't try to resist but fell into a sitting position while Cherry kept tickling her.

"You'd better stop," said Adagio. "She's gonna pee herself."

"Oh, I'm sure she doesn't mind," said Rarity.

Cherry paused for a few seconds to let her catch her breath, and then he tickled harder.

Rainbow laughed harder, and soon a hissing sound was heard. The crotch of her white dress turned yellow and wet, but she didn't stop laughing.

Everyone was amused and giggled a bit, even Rarity.

Cherry kept tickling for about fifteen seconds after Rainbow finished peeing, and then he helped her up. "Did you like that?"

"I loved it," said Rainbow Dash. "And now I don't have to go anymore!" She chuckled, blushing lightly and remembering their first date.

"Well, Flash, now you know what to do at our wedding next month," said Sunset. Flash Sentry chuckled, also looking forward to it.

"You really needed to go, didn't you Dashie?" Fluttershy giggled, finding it highly amusing that Rainbow Dash peed in her dress, and by now feeling very little embarrassment whenever she did the same. Sometimes she'd even pass up a bathroom so as to not hold the other girls up, perfectly fine with using her dress as a toilet if she didn't make it to the next one.

Rainbow Dash continued the party in her wet dress, and once it was over, she and Cherry climbed into her car, Rainbow Dash, not caring that she was getting her pee on the driver's seat. Besides, the seat was already dirty from her sitting on it in her grungy outfit. The car said "Just married" on the back, and they had already packed what they would be taking with them, including a plastic cover to protect the bed from Rainbow's grunginess.

"Are you going to wear your dress on our honeymoon?" said Cherry.

"We'll see how dirty and stinky it gets after a week straight with no washing," said Rainbow Dash.

"I look forward to it. And we can drive with the windows closed if you want, Dashie. I REALLY don't mind."

"Even with the pee smell?"

"Especially with the pee smell. And don't be shy about farting either."

Everyone waved after Rainbow and Cherry as they drove away.

...

A week later, they returned, parking at Applejack's farm. As they got out of their car, Cherry was looking very clean and wearing a white T-shirt and a pair of jeans. Rainbow Dash was still wearing her wedding dress, which was much dirtier than before and smelled as bad as her.

It had bits of coffee, cider, soda, hot chocolate, gravy, sauces, and frosting splattered all over it from eating and drinking messily. It was hard to tell by looking at it, but it also had traces of whip cream on its butt because Cherry had pranked her by making her sit on a whip cream pie, which she found hilarious.

And its skirt was stained yellow at the front and back because she had wet herself twice more on her honeymoon: Once when Cherry tickled her, and once when Cherry put her hand in warm water to make her wet the bed.

Plus, once more on the way back earlier today.

...

They had gotten stuck in a traffic jam. Rainbow Dash had drank a lot before the drive and was fidgeting hard in her seat.

"Hurry up!" she said. "I REALLY gotta go!"

"You already peed in that dress three times," said Cherry. "Just let it all out. You know it'll only make me like you more."

Rainbow giggled slightly and started to pee full force. "Ahhhhh..."

...

"Howdy, Rainbow," said Applejack, walking outside. She sniffed her. "Yup, you smell as bad as ever!"

"I'm due for a rinse today," said Rainbow Dash. "But I wanted to have fun trashing this dress for the last time."

Applejack looked at all the stains on the smelly wedding dress. "Ain't it trashed enough already?"

"Not nearly as much as it's gonna be now," said Rainbow. "All right Cherry, do it."

Cherry picked Rainbow up and threw her into the pigpen. Rainbow splashed butt-first into the mud. She immediately started rolling around in it. Before long her dress was saturated brown.

"She looks like she's enjoyin' herself," said Applejack with a chuckle.

"That's my Dashie," said Cherry.

After a few minutes of playing in the mud, Rainbow sat upright and started to pee.

"You just went," said Cherry, more amused than anything.

"That was an hour ago, and I still had a lot left to go through me," said Rainbow Dash. She laughed as her dress grew wetter and wetter. She could only imagine the state of her shorts and pink panties underneath.

...

Rainbow showered off, still wearing her dress, but not using any soap besides shampoo for her hair. When her shower was done, she removed her dress (which was still stained in many places), revealing her white shirt, blue jacket, and black compression shorts, which were now completely soaked but still smelled bad. She had left her dress on all week and only pulled her shorts down to go to the bathroom.

She blow dried herself and stepped outside.

"How do I look?"

"Cleaner than before," said Cherry. "And very beautiful."

"How do I smell?"

Cherry sniffed her. "Just the way I like you."

Rainbow let out a loud fart, and she, Applejack, and Cherry laughed.
