They say curiosity killed the cat, and to many that was a major understatement, one of which included Rarity, the fashionista of Canterlot High herself. At least after this day she would think so.

It began like any other, after getting dressed and having breakfast, Rarity exited her home and began to head on her way to school. Her sister Sweetie Belle had already gone on ahead of her and her friends lived in separate parts of town, so it almost looked like she was going to be walking to school alone. Luckily though, there was one friend that lived a bit closer to her, that friend being Rainbow Dash.

As she walked down the pathway of her house, Rarity spotted her jockette friend at the other end of it, waving to her.

"Hey, Rarity!" she said.

"Morning Rainbow Dash." Rarity smiled. "Ready for school?"

"You know it!" Rainbow nodded.

"Let's go." Rarity declared.

"Right!" Rainbow agreed as the two began to walk down the sidewalk together in the direction of the school.

"Thank you again for walking with me to school again." Rarity told her. "Honestly, walking alone can be so terribly… what's the word?"

"Dull?"

"Yes! 'Dull' indeed."

"How come you don't just drive to school? You know how, right?"

"I can, but like Fluttershy said; everyone must do their part for the environment."

"Yeah, I guess so…" Rainbow admitted.

The two of them were quiet for a moment, the only sound between them was their footsteps as they walked. After a minute of no one talking, Rarity decided to break the silence.

"It's nice to breath in the fresh morning air when walking, plus it's good exercise."

"Hey, can't argue with that." Rainbow replied.

"I personally prefer exercising my brain and my bare hands then legs, but that is just me." Rarity stated.

"You sure about that?" Rainbow inquired.

"Yes, why?" Rarity responded.

"Nothing, just…" Rainbow Dash started to say.

"Just what?" Her fashionista friend pressed.

"Well… you might wanna do a bit of running… you know, to work off that thing." Rainbow answered, gesturing to behind Rarity for a brief second.

Rarity looked behind her back in confusion. "What? What thing? Is there something on me?"

"Uh…" Rainbow muttered, trying to think of the right words.

Rarity suddenly froze, her eyes filled with concern. "Rainbow, is there a bug on my skirt?"

"Oh… not exactly…" Rainbow told her. "It's more like… what's under it that's the problem."

"Under it?" The fashionista questioned, confused.

"Yeah… something that's kind of… well, big." Rainbow finally said.

"Rainbow, just what are you trying to-" Rarity paused, her cheeks flushing a little as realization hit her. "You're not saying that…"

"I didn't say anything!" Rainbow Dash denied, nervously.

"But you were thinking it!" Rarity pointed out. "You were thinking that I have a large derrière, weren't you!?"

"Well… I mean, it kind of is." Rainbow smiled with worry.

Rarity gasped and looked back at her skirt. "It is not!" She denied as she held the back of it down, protectively. "Why would you even make such an accusation like that!? I guess a better question would be why were you even thinking about my derriere in the first place!?"

"I wasn't!"

"Oh really?"

"Yes! It was just an observation! That's all!"

"You were trying to hurt my feelings!"

"Without meaning too you mean." Rainbow pointed out before she noticed something. "Oh, and speaking of observations…"

"Oh, what is it now?" Rarity responded, still pretty fumed at having her figure insulted. She turned and saw a bus beginning to head their way. "A bus?"

"Yeah, a bus for Crystal Prep." Rainbow revealed.

Even at a distance, Rarity was able to see that it definitely was a bus from Crystal Prep, it's black base color and purple insignia giving it away.

"Oh yes, I see." Rarity acknowledged.

"You know… they still haven't apologized for gloating all the time at the Friendship Games." Rainbow reminded.

"So?" Rarity questioned, not getting it.

"So, I think it's time to give them a little payback." Rainbow replied, a grin on her face.

"What are you saying?" Rarity asked, suspiciously

"What I'm saying, is it's time for them to have a taste of their own medicine." The athlete girl turned around, her back toward the street.

"Umm, Rainbow Dash?" Rarity started, while her jockette friend leaned her upper body slightly forward. Rainbow continued to grin as she put her thumbs underneath the waistband of her pants and underwear.

The bus was drawing near, and Rarity gulped as she realized what her friend was planning to do, and it horrified her.

"Rainbow please, if you're about to do what I think you're going to do. So help me…" she started to say, but it was too late.

Rainbow looked behind her with a smirk, watching as the bus was almost about to pass them, sticking her skirt clad butt out a little further. Then, without hesitation, she quickly whisked her pants and underwear down to her knees. Her bare blue butt was right in full view for the crystal prep students as their bus approached.

Rarity was shocked and gasped sharply while she watched her friend moon the bus. "Rainbow Dash! Pull up your pants immediately!" she exclaimed.

"And miss a chance to moon some Crystal Prep wannabes? Never!" Rainbow declared as she impishly wiggled her rear.

Some of the students in the bus who were looking out the window were unfortunate enough to witness Dash's big blue butt mooning them. One of the students glowered furiously as Rainbow shook her rump at them while others were disgusted and covered their eyes as they turned away.

Their voices were unheard but most of them indeed looked like they were yelling 'Ew!', 'Yuck!' and 'Gross' at the top of their lungs.

Rainbow laughed as she mooned the passing bus. "There's a blue moon out today! Haha!" She laughed while shaking her rear, making the flesh on her cheeks jiggle with each shake.

Rarity was still horrified as she watched Rainbow shaking her tush at the passing bus, she wanted to turn away and she almost threw up in her mouth but at the same she couldn't stop looking.

"Rainbow, this has gone on for far too long! Now pull up your pants right now, young lady!" The fashionista proclaimed, angry, but also partly feeling strange. A feeling she couldn't really describe at the moment.

It was only until the bus finally left that Rainbow finally began to listen. "Alright, alright, don't be such a prude…" The Athlete rolled her eyes as she pulled up her bottom clothes.

Rarity breathed out a little sigh of relief as it was finally over, watching as the bus headed away from them. "I can't believe you actually did that." She said, her tone voicing her displeasure.

"What's the big deal? It's not like I'm gonna see any of them soon and it's not like there's a law against it." Rainbow pointed out.

"Actually there is, it's called 'indecent exposure', look it up!" Rarity told her.

Rainbow looked over with an unamused look at her annoyed friend. "You really need to lighten up Rares."

"Are you calling me uptight!?" Rarity accused.

"No… I mean thinking it but…" Rainbow began.

"Well! I never!" Rarity huffed, insulted before she started to walk away. Rainbow quickly ran over and caught up with her.

The athlete decided to try and brighten the mood a little. "Come on, you've gotta admit though, their reactions were priceless. I mean, did you see the look on some of their faces?"

"Did you see the look on mine?" Rarity shot back.

"Yeah… that was a totally different shade of red for you." Rainbow pointed out.

Rarity simply sighed. "I can only imagine the many other times you've done that."

"More than you think…" Rainbow confessed with a grin while she rubbed the back of her head.

"Let me guess… were they other rivals of our school?" The fashionista asked.

"Oh, not just them." Rainbow Dash admitted.

"Who… Wait, no, forget it, I do not want to know." Rarity stated, firmly as she turned her head away.

"Yeah… I figured you were gonna say that." Rainbow grinned, cheekily.

"Honestly, how could you possibly get so much excitement from something so immature and distasteful?" Rarity questioned.

"Hey, don't knock it till you've tried it." Rainbow told her.

The purple haired girl gasped, almost sounding insulted. "Please! You would never see me doing something as crude and indecent as that!" she proclaimed.

Rainbow gave her a sly grin. "We'll see about that," she said with an almost knowing look before she went on ahead.

Rarity gave her a suspicious narrow glare, before glancing at the back of her own skirt and rear. She thought for a moment about what her friend just said, before huffing in annoyance and following her.
