Rainbow Dash, Rarity, and Pinkie Pie groaned in extreme discomfort.
They had been hanging out on the beach. Rainbow Dash was wearing her usual dark pink miniskirt with skintight black shorts, Rarity was wearing her purple shorts, and Pinkie Pie was wearing her jean shorts, all perfect for a summer day at the beach. Rarity and Pinkie's shorts were shorter than Legend of Everfree would sometimes show. They had been drinking a lot of water and other beverages, as it was a hot day out, and now they needed to pee very badly.
All the beach bathrooms but one happened to be closed, and there was line of five girls for the only remaining one (they were all single bathrooms). Rainbow Dash stood at the front because she thought she needed to pee the most. Rarity stood behind her, and Pinkie Pie stood at the rear, though she had to pee even more badly than Rainbow Dash.
All three girls held themselves and fidgeted hard. It only took a minute but it seemed like hours, for the girl who was inside to get out, and the girl at the front of the line to enter the bathroom.
Aria Blaze was walking by, wearing her usual outfit that included purple jeanlike pants, when she noticed the three desperate girls at the back. The other four girls in front of them didn't look like they had to go nearly as bad as her three enemies did. She remembered how they had taken away all her power, and quite conveniently, the opportunity had presented itself for revenge.
Aria quietly tiptoed behind Pinkie Pie, and then, crying out very loudly, she grabbed Pinkie hard from behind.
Pinkie was startled, let out a high-pitched shriek, and immediately began peeing herself. Rainbow Dash and Rarity were a little startled too, and turned around to see Aria looking smug as Pinkie flooded her jean shorts, blushing a little. The sight made them both uncomfortable, and Rainbow Dash felt a bit of pee leak into her shorts.
Aria shoved Rarity into Rainbow Dash, knocking both to the ground as Pinkie kept peeing, sighing of relief at this point. Aria kicked Rarity hard in the butt, causing a bit of pee to leak into her underwear. She whimpered and shot her hand between her legs, but Aria kicked her again, and again. Rarity lost control and began peeing her shorts, blushing profusely.
"Hey, what's the big idea?" said Rainbow Dash, who was feeling more uncomfortable watching Rarity pee. And Pinkie was still peeing.
Aria only began tickling Rainbow's armpits. Rainbow Dash started to laugh hard, desperately trying to hold it in, but Aria tickled harder.
"HAHAHAHAHAHAHAHAHAHAHA! STOP! HAHAHAHAHAHAHA! I'M REALLY TICKLISH! HAHAHAHAHAHA"
Aria tickled harder. Pinkie was still peeing.
"STOP! HAHAHAHAHAHA! I CAN'T TAKE IT! HAHAHAHAHAHA! I'M GONNA PEE! HAHAHAHAHAHA!"
Aria tickled as hard as she could, and before long Rainbow was wetting her shorts, still laughing her butt off.
Rarity finished peeing, and got to her feet, ashamed beyond belief.
Aria stopped tickling Rainbow once she had finished peeing. "Ha! That'll teach you to mess with the Dazzlings!"
Once Rainbow stopped laughing, she blushed, feeling embarrassed that she, the best athlete in the whole school, and popular singer of the Rainbooms, had wet herself.
Aria walked away, satisfied at what she had done.
"I can't believe she did that to us," said Rarity. "She's so vile."
"We'll get her back for this," said Rainbow. "Somehow."
Pinkie finally finished peeing. "Ah, that's better."
...
The next day, Aria walked back to the beach, again wearing her usual outfit. It seemed a bit of a long shot that they would show their faces here again after what had happened last time, but she hoped she'd get the chance to do this again.
To her delight, she saw them. Rainbow Dash, Rarity, and Pinkie Pie, in the same outfits which had been washed and dried nicely. There were no girls in front of them this time, but they were all holding themselves and squirming. They must really need to go.
Aria quietly sneaked up behind Rainbow Dash, who stood at the rear, while Pinkie Pie was at the front, looking as though she were about to burst. Aria raised her hands to startle Rainbow Dash...
And then Rainbow turned around and kicked Aria in the face, knocking her to the ground.
Pinkie got out some ropes and tied Aria's feet together while Rarity tied her arms behind her.
"How did you know I was behind you?" said Aria as Rarity set her down so she was laying on her back.
"We knew you couldn't pass this up again," said Rainbow Dash. "And just so you know, we didn't even need to go!"
"Speak for yourself, Dashie!" said Pinkie Pie, who had resumed holding herself. "I really do have to go!"
"I told you not to drink too much before we got her," said Rainbow Dash.
"I couldn't help it! I drank five sodas, three slushies, eight ciders, and a glass of water!"
"Try to hold it until it's time." Rainbow Dash opened up a bag they had brought with them and pulled out some large bottles of soda. Rainbow and Rarity each drank one each rather quickly.
"Hey, I want some too!" said Pinkie, downing a bottle in one gulp. "Oops! Bad idea!" She fidgeted even harder.
"Why do you get all the drinks?" said Aria. "Give me some!"
"As you wish!" said Rainbow Dash, and she held out a bottle for Aria to drink. Aria guzzled it down at a shocking speed.
Rainbow Dash bought some slushies from the nearby shop. She and Rarity each drank one. Pinkie drank half of hers, but a twinge from her bladder made her drop it next to Aria, who drank the rest of it.
"Oooh, how much longer?" said Pinkie Pie half an hour later, desperately squirming as she felt the pee sloshing around inside her. "I REALLY need to go!"
"You can hold it, darling," said Rarity. "Wait for me and Rainbow first."
"Wait for... what are you talking about?" said Aria.
"Our revenge!" said Rainbow Dash. "We're gonna pay you back!"
Aria didn't know what they were planning, but she had a sinking feeling it wasn't going to be very pleasant. Not after what she did.
And why wasn't Pinkie using the bathroom? Aria was sure it wasn't occupied at this point. Now that she looked around, the other bathrooms were no longer out of order.
It was then that Aria felt a sudden urge to pee. In addition to the soda and slushie she'd drank, she had also drank a few cups of coke, a glass of milk, a box of juice, and some water before coming here. She fidgeted against her ropes. "Untie me now! I have to go to the bathroom!" It suddenly hit her what their revenge might be. They were going to make her wet herself. Or was it? She had been the one who demanded the soda, and they couldn't have known how much she had to drink before their trap.
"Just hold it," said Rainbow Dash.
"This is a rather unexpected bonus," said Rarity.
Fifteen minutes later, Pinkie leaked a bit into her underwear. "Oooh! I don't think I'm gonna make it..."
"Come on, just a little longer Pinkie!" said Rainbow Dash. "It shouldn't be much longer."
"What shouldn't be?" said Aria, struggling against her ropes for the twentieth or so time, her need to pee growing greater.
"You'll see," said Rainbow Dash, giving her an ominous smirk.
Fifteen more minutes went by, and Aria became even more desperate. In her current state she couldn't even hold herself or cross her legs, so she could only fidget hard and try to take her mind off her very full bladder.
"I need to pee really badly," said Rainbow Dash, who had started holding herself. "Rarity?"
"So do I," Rarity said, seeming unusually composed in spite of this.
"Pinkie Pie?"
"I'm about to burst over here!" Pinkie was sitting with her legs crossed, fidgeting hard and a pained look on her face.
"Then it's time!" said Rainbow Dash.
Pinkie Pie stood up, leaking a bit more into her shorts, which were now damp, but she barely managed to hold the rest of it in.
Rainbow Dash, Rarity, and Pinkie Pie walked over to Aria and stood directly above her, with each foot on either side of her so she was positioned directly between their legs.
"I didn't think you'd want to do this part too," said Rainbow Dash to Rarity.
"It is the perfect revenge," said Rarity. "It's worth sacrificing a little dignity to give her karma. And we can just go for a swim when this is over."
"What are you doing?" said Aria, becoming even more nervous, and feeling like she was seconds away from wetting her pants.
"You made us wet ourselves," said Rainbow Dash. "And now we get our revenge on you... by wetting ourselves again!"
"Is it time now?" said Pinkie Pie, who was incredibly desperate and dribbling a bit.
"Now!" said Rainbow.
Rainbow, Rarity, and Pinkie let go all at once. In seconds their shorts became soaked, and streams of urine poured from between their legs all over Aria, drenching her within five seconds.
"Aaaah! What is this?" said Aria. She had never imagined anyone would ever do something like this to her. She cringed at the feeling of the warm liquid as it splashed over her, soaking her shirt, her purple pants, and her underwear, and she was helpless to stop it. The air around her was thick with the smell of pee.
"It's called a golden shower," said Rainbow Dash, still peeing. "It's a way of humiliation. But to some people, it's a fetish." She blushed lightly. "You wanted us to pee in our shorts? You got it!"
"I never thought I'd stoop to such things, but it's worth it!" said Rarity.
"Ahhhhhhhhh," sighed Pinkie in relief, allowing her stream to go harder. She had to pee the most and felt the most immensely relieved. Plus she really enjoyed the feeling of peeing her shorts.
It wasn't long before the warm shower of pee made Aria lose control. She began peeing her pants, although this was impossible to notice because of the waterfalls raining down on her.
About a minute into the golden shower, Rainbow Dash and Rarity finished, but Pinkie Pie was still peeing, and so was Aria. With only Pinkie's stream remaining, Rainbow Dash and Rarity could see that Aria was peeing herself, and laughed. Aria stopped peeing 30 seconds after Rainbow and Rarity.
Pinkie peed on Aria for a total of two and a half minutes, sighing in relief once she was done, but also looking a little disappointed that it was over.
Aria had never been so humiliated in all her life, even though no one else was around at the moment. She was completely soaked in urine, some of which was her own.
Rainbow Dash flipped Aria facedown with her foot and patted her butt lightly. "If I were you, I wouldn't think of another revenge plan."
"Aw, don't say that!" said Pinkie Pie. "If she does, we get to do this to her again!" She was so excited she peed again.
"It was kind of fun," said Rainbow, who had also enjoyed it.
"Now, I suggest we go for a swim before someone comes and notices us," said Rarity.
The three girls ran toward the lake.
"Hey, are you gonna just leave me here?" said Aria.
"Relax," said Rainbow. "We'll come back for you, after we wash off and splash about for a few hours."
"A FEW HOURS?" said Aria. She did not want to be in this state for that long, especially if someone noticed her. There was the chance they'd untie her early, but chances were high they wouldn't want to touch her in her wet state, or that they'd be unwilling to do her a favor after all she had done. There was always Adagio and Sonata, but she shuddered at the thought of Sonata finding out what had happened to her.
"Oh no... I really have to pee again."
Author's Note
I hope it was adequate for my first golden shower story, even though it's probably still inferior work. And I know Rarity would never actually do that, but like I said, stretchy scenarios, and there's been stretchier fetish stories.
