Rarity was at the spa with Fluttershy, getting "the usual". It seemed like another normal day at the spa, until...
"So, Sapphire Shores is doing a musical play this Tuesday," said Rarity.
"Sounds lovely," said Fluttershy.
"The main character is a bunny, and she wanted me to design the costume."
"Sounds cute. I'd like to see it."
"How would you like to be the bunny instead?"
"Oh. Um... I don't know..."
"I'm sure you'd pull it off far better than I could."
"I don't think so. Remember that time I was modeling for you? It's really not for me."
"You were able to do Hearth's Warming Eve just fine."
"That was a little different. The spotlight was on all of us, not just me."
"But this time you get to be an adorable bunny rabbit!"
"Well... if you really want me to." Fluttershy didn't want to let Rarity down, but she was feeling very nervous about this.
...
Rarity designed a pink bunny costume. Fluttershy felt a bit better at how cute the costume looked. Also the fact that it would hide her mane and tail, and Rarity would put pink makeup on her face to go with the costume, so there was the chance that most ponies in the audience wouldn't recognize her.
Fluttershy spent the next few days wearing the costume and singing the songs. She practiced singing in front of the animals, though this was always easy for her. By the end of Monday, she was sure she was as ready as she was ever going to be.
...
Tuesday morning, at the time of the play, Fluttershy stood backstage, in her bunny costume and with pink makeup on her face. She was starting to feel nervous again, but she took a deep breath and tried to remember to relax, and imagine everyone in the audience were animals.
Rarity stood next to her. "How are you feeling, Fluttershy?"
"I don't know if I can do this."
"You'll have to, it's almost time."
"And then," said Spike, the narrator, "in came the Pink Bunny!"
"Break a leg," Rarity said quietly.
Fluttershy gulped, and walked onstage. The spotlight shone on her. She froze, looking at all the ponies whose eyes were on her.
A pony in the audience coughed. Fluttershy tried to sing her first song, but she couldn't get the words out.
"Oh no, I think her stage fright's getting the best of her," said Rarity.
Try as she might, Fluttershy couldn't start singing. She tried to imagine they were animals, but her stage fright was too intense. All the ponies looking at her onstage was too much for her, and she wet her costume. The ponies started laughing, and Fluttershy became aware of the warm wetness that was spreading through her crotch and running down her legs. She blushed beet red and ran off the stage in tears.
Rarity felt awful for Fluttershy. How embarrassing, to wet oneself onstage. She ran out, determined to make things right.
Fluttershy ran for about a minute before she stopped, and sat under a tree in her wet costume, sobbing. She was never going to live this down. She had just peed herself in front of an audience. In Rarity's costume, and let her down, at that. Her tears and hooves washed the makeup off her face.
"Fluttershy!" Rarity ran up to her. "Is everything all right, darling?"
"N... no." Fluttershy sniffled. "I peed in my costume in front of all those ponies. They're gonna make fun of me forever."
"No they won't," said Rarity. "I don't think anyone else even knows it was you, with the makeup on your face and your mane and tail hidden. I'm the only one who knows, and I won't think any less of you." She patted Fluttershy on the back.
Fluttershy felt a bit better at this. But... "I'm so sorry I ruined the play for you."
Rarity thought for a minute and boldly made a decision. "The play can still be salvaged. I shall take your place. Step out of your wet costume."
Fluttershy removed her costume. "How are you going to make a new costume before the audience gets restless?"
"I'm not." Rarity put on Fluttershy's costume. She cringed a little at the warm wetness on its crotch and legs, as well as the pee smell, but was willing to put up with it for Fluttershy.
"Oh my," said Fluttershy. "I... I can't ask you to do that."
"This is what I want to do," said Rarity. "Everyone will think it was me, and I'll perform to the best of my ability, so hopefully they'll forget about my supposed accident."
"I wouldn't wish an onstage pee accident on anyone."
"I insist. It's the least I can do for getting you into this."
"Well... if you're really really sure..."
"Go home and wash up and spend some time with your animals. Then when the play is over I'll treat you to the spa, and you can put this whole day behind you."
"O... okay... I really hope you'll get through this all right." Fluttershy walked back towards her cottage.
Rarity returned to the stage. She noticed that Fluttershy's puddle had been cleaned up. "I am dreadfully sorry for the delay. I drank too much and desperately needed the bathroom, and I couldn't hold it. But I came back because I want to give you all a good show, wet or dry."
She started singing the first song. Spike thought she looked extra beautiful singing in a pee-soaked costume, but he had a feeling she wouldn't appreciate this.
The other ponies in the audience felt along the same lines, and were more eager to show it. They stopped snickering and chuckling at random moments and cheered whenever Rarity finished a song. Rarity was becoming more and more comfortable with her current state as the play progressed.
When the play was over, Spike said "Let's hear it for Rarity, the Pink Bunny!"
The audience applauded loudly, cheering and clapping their hooves. Rarity started to tear up, not with embarrassment, but joy at how the audience loved her even though she had seemingly peed in her costume. Speaking of which, she crossed her back legs and fidgeted slightly, for she had to go to the bathroom herself.
"That was sensational!" said Sapphire. "And, unless I'm much mistaken, do you need to pee again?"
"Yes." Rarity blushed lightly.
"Would you mind wetting yourself for us again? You make wetting look stylish."
"I couldn't. It's so unladylike." Rarity crossed her legs tighter.
"You already did it once, so what's a second time?"
Rarity thought for a moment. She hadn't been the one to pee in this costume, but everyone thought she did, plus it was already soaked in Fluttershy's pee, so surely it couldn't hurt. Rarity took a deep breath and let go and peed, sighing of relief and blushing beet red as the crotch and legs of her costume grew even wetter. She couldn't believe that she was deliberately peeing herself in front of a crowd of ponies. Another puddle rapidly formed on the stage.
Instead of laughing, the audience cheered. Rarity felt less ashamed and foolish at this and did a hair flip so that her mane came out from the hood of her costume, striking a pose as she finished wetting herself, trying to look fabulous.
"If there's one pony that can wet in style, it's Rarity!" said Sapphire.
"Way to go, Rarity!" said Spike.
...
Rarity met up with Fluttershy at her cottage. "Are you ready to go to the spa, darling?"
"Yes. How did everything go?" Fluttershy braced herself.
"They loved me singing in my wet costume. They thought it made the show even better. Not in a 'making fun of me' way either, but in a 'I make wetting look stylish' way. Sapphire actually asked me to wet myself again, and I did."
"Really?" Fluttershy felt even closer to Rarity now they had both wet themselves.
Spike walked up to Rarity. "So many ponies are saying they want a bunny costume like that, and calling your performance "Wetting in Style".
Rarity blushed lightly. "Tell them I'll get on it after a trip to the spa."
After a relaxing time at the spa which both Rarity and Fluttershy thoroughly enjoyed, Rarity made more pink bunny costumes and sold them at Carousel Boutique.
The next day, mares all around Ponyville were wearing these costumes and peeing in them. Among them were Lyra, Sweetie Drops, Derpy, Amethyst Star, Golden Harvest, Berryshine, Roseluck, Cherry Berry, and Pinkie Pie. Most of them did hair flips trying to imitate Rarity, except Pinkie, who was clearly just wetting her costume for fun. Rarity wasn't surprised, she had laughed at wetting her exercise shorts on more than one occasion.
"Looks like you started a trend," said Fluttershy with a light blush and a smile.
"I didn't know such a thing could happen with... that... but it looks like they love it. I'd say it all turned out. How are you feeling?"
"Much better." So many ponies were wetting themselves now because they thought it was fun, because Rarity made it look good. And no one but Rarity knew who had originally peed in that costume, and not only was Rarity still by her side, but she had also wet herself for real, and come out of it without any shame or ridicule. She agreed with Rarity, it did all turn out.
