Wet Flutterdash

Rainbow Dash and Fluttershy had been wetting a lot more since their first wet day/night, and told their friends about it. None of them minded one bit.

Twilight Sparkle had said it wasn't that unusual and given a lengthy description about "omorashi", a fetish for wetting oneself.

Sunset Shimmer had said something like that would never affect their friendship, especially after all they'd forgiven her for.

Pinkie Pie, naturally, had found it funny and would sometimes tickle Rainbow Dash and Fluttershy into wetting themselves, which they liked, and in turn, sometimes when Pinkie really needed to pee, Rainbow Dash would either tickle her or let out a loud fart, both of which would make Pinkie pee her jean shorts, teal romper, or pink skirt from laughing too hard, and she would always find this funny as well, to the point that whenever she had to pee around Rainbow Dash, she looked in her direction as if asking her to induce a laugh wetting.

Applejack had taken advantage of this opportunity for friendly competition and challenged Rainbow to holding contests. Sometimes Rainbow won, sometimes Applejack won, sometimes they tied and wet themselves at the same time. Sometimes Fluttershy would add an extra challenge by wetting herself in front of them, after holding alongside them, and sighing of relief. Whoever won the holding contests would let go and wet herself shortly after. Applejack usually wore tight jeans or short, tight jean shorts for this.

And Rarity had said that she didn't care how unladylike her friends were, and that it wasn't a big deal. She was a little surprised that Fluttershy found it to be fun but was glad she didn't have to worry about a humiliation factor in wetting anymore. Furthermore, after witnessing a few wettings, Rarity revealed that she wet the bed, and knowing Rainbow and Fluttershy wet for fun made her feel less ashamed of it.

"If that's why you don't wanna sleep in the same bed as me, don't worry your pretty li'l head about it none," said Applejack. "Ah don't mind if you pee all over me when we sleep. In fact, whenever you wake up wet, I'll wet my pajamas too."

"Awww," said Rarity, hugging Applejack. "You don't mind that I sleep in my underwear, do you?"

"Not even a little bit." Applejack smiled and slapped Rarity's butt. Rarity giggled.

...

Soon, the day of Rainbow Dash and Fluttershy's wedding arrived. Rarity had made wedding dresses for both of them. By their request, while still looking fancy, the skirt wasn't overly wide.

"If you have to go to the bathroom while wearing the dress, you can just go right there," Rarity had said. "I don't mind."

Rainbow Dash and Fluttershy stood at the altar in their wedding dresses. Underneath, Fluttershy wore pink panties, and Rainbow Dash wore pink boyshort panties. She planned to give Fluttershy many upskirt views on their honeymoon and would enjoy whatever comments she made about her cute underwear.

Both had also drank lots of water, ice tea, and, in Rainbow's case, cider today. So they needed to pee rather badly. They could have used the bathroom before the wedding, of course, but they had their own little plan for this.

"Do you have to pee as much as I do?" Rainbow whispered to Fluttershy.

Fluttershy nodded with a cute smile on her face.

After they exchanged their vows and I do's, Rainbow and Fluttershy kissed. As they did, a hissing sound could be heard emanating from both of them as they peed in their dresses. Their panties took most of the damage and pee flowed down their legs and made a big puddle at their feet. Pee also dripped off the skirts of their dresses.

"That's nothing to be ashamed of," said Mayor Mare. "Wettings are not uncommon at weddings."

Rainbow and Fluttershy just giggled.

After the reception was over, Rainbow and Fluttershy got ready to leave for their honeymoon.

"Have a fun, wet honeymoon," said Applejack, winking at them.

"Don't worry, we will," said Rainbow.

In addition to the punch they drank at the wedding, Rainbow and Fluttershy also stopped at the convenience store for a soda and an extra large slushy for each of them. They had barely hit the road when they had to pee again. They had fun holding it for a bit, and when the urge got intense, they let it out in their wedding dresses again. This time the front of the skirts were tinted yellow, and they were sure the same applied to the butt of their dress, given that they were peeing in sitting position. Their panties were absolutely soaked. They giggled at the contrast of girls in fancy dresses doing something so dirty.

Then Rainbow Dash let out a short, loud, wet fart and chuckled.

Fluttershy giggled, and then a long, loud, deep-pitched fart made its way out of her. BBBBBRRRRRRT!

...

A week later, Rainbow and Fluttershy returned. They had not washed or changed out of their dresses since the wedding, so they smelled bad and their dresses were dirty, especially the skirt parts of them, because although they never messed themselves, whenever they needed to pee they would go in their dresses. Sometimes they would give each other golden showers through their panties, which they both enjoyed. So their dresses were stained all over. Sometimes they would pee on each other while being spanked with their skirts up.

They met up with their friends at Applejack's backyard.

"Welcome back... Good heavens, have you washed since the wedding?" Rarity asked.

"Not once," said Rainbow proudly.

"Or changed out of these dresses," said Fluttershy with a cute smile.

Rarity sniffed them and recoiled. They smelled strongly of urine and body odor. "I... hope you had a fun honeymoon."

"You bet we did," said Rainbow. Fluttershy nodded.

"But right now you really need a bath."

Fluttershy sniffed her armpit. "Yes, we do. We really stink."

"How would you like to take a bath in our wooden tubs here?" Applejack asked.

"Sure, that'll be fun," said Rainbow.

"We can stay in our wedding dresses, right?" Fluttershy asked.

"I don't see why not," said Rarity.

Applejack filled two wooden tubs with warm, soapy water. While they waited, Rainbow and Fluttershy wet themselves one more time. Still in their dirty, smelly, pee-soaked dresses, Rainbow Dash climbed into one tub, and Fluttershy climbed into the other. Applejack and Rarity poured a bucket of water over Rainbow Dash and Fluttershy, respectively, and then lathered their hair with shampoo. Once their hair was covered in suds, Applejack scrubbed Rainbow Dash hard with soap while Rarity scrubbed Fluttershy more gently. Both Rainbow and Fluttershy enjoyed taking a bath like this. Rainbow farted in the tub at one point, which made Pinkie giggle.

Then, Rainbow and Fluttershy positioned their butts in the air and Applejack and Rarity scrubbed them. Rainbow and Fluttershy didn't really mind anyone other than each other doing this, not even when they lifted their skirts and washed their dirty underwear, but of course they found it most fun with each other.

Finally, Rainbow and Fluttershy were mostly clean, though their dresses still had pee stains on them. They went home and changed into their sports outfits again, which hadn't been washed since the last time they had wet them so, while dry, their shorts smelled of pee. Not that it mattered. As they headed to Pinkie's house for a welcome back party, after rubbing their butts together, Rainbow and Fluttershy knew they would go into their sleeping bags wet tonight!
