Fire.
Sunset Shimmer was used to a lot of weird things since coming to Earth from Equestria. The very idea that using only two limbs to walk instead of four threw her off for a while, but after a few too many drunk homeless people began whistling at her strange behavior and a few stray dogs gave her some curious sniffs, she realized that no, she was in the wrong.
So then she stood up, and all was right in the world.
Well, maybe not her world, but the world in which she now resided. And just as she was getting the entirety of Canterlot High under her control, who came to spoil shit?
Princess Twilight Sparkle and her damn dog, too.
Granted, it was kind of her fault cause she took her big crown thingie, but really, how was she to know that the pony princess would follow her through and try to take it back?
So bla bla bla, friendship lessons, magical rainbow powers, and bam, Sunny Buns here was now a good guy.
Well, sorta.
She was good in the sense that she was no longer beating up Snips and Snails for lunch money because she couldn’t afford food, yet rode around on her bike and paid the insane insurance for a teen riding a bike.
No, instead, she participated in sports.
Rainbow Dash called it awesome. Applejack said it was good for her. Even Fluttershy said that, um, you know, it would probably help with that bit of a muffin top you had going on… please don’t hurt me.
So this is where we found Sunset Shimmer, in the girls locker room, after a long day of running around in circles, yet they were oval shaped.
“Good job today, Sunset! You did awesome!”
Sunset Shimmer gave a thumbs up to her rainbow haired friend, and then promptly collapsed onto one of the benches, face up, glaring at the slightly blinding fluorescent lights above her.
“Sunset, darling, are you alright?” Rarity was next to speak, asking with a hint of worry as she removed her stinky, sweaty work out clothes.
“Yeah, Rares, I’m fine. It’s just… I’m still getting used to focusing on two legs instead of four, and after a while, I try to go back to the old ways and I end up hurting myself.”
“Oh, right, the pony thing.” Rainbow shrugged, tossing her exercise bra into her dirty clothes filled locker. “You’re doing fine out there, girl. Relax.”
“I agree with Rainbow, darling. You’re doing fantastic! And you’re losing that muffin top!”
Sunset rolled her eyes. “Gee, thanks Rares.”
“Yeah Rarity, gosh, don’t bring that up. You know she’s trying for a bod like this!” Rainbow proceeded to run her hands along side her body, motioning to her bare chest and six pack clearly on display.
“Yes, although flat chests are so last year.”
Rainbow blinked. “Wait, they’re what?”
Ignoring Rainbow, Rarity walked over to sit beside Sunset on her bench, still laying on her back, clothes soaked with sweat.
“Darling, don’t fret so much. You’re getting there. I’m sure it is a lot harder on two legs instead of four, but just think of all the extra work you’re putting into it! Why, I bet if you went back to Equestria, you’d be the most beautifully fit pony in all of the land!”
Sunset blew a raspberry. “Yeah, except most stallions want a thicker mare so she can handle their weight when mounting.”
Rainbow threw on a simple T shirt, ignoring any semblance of needing a bra. “Mounting what?”
“Oh rest assured, darling, so long as you’re here, you have no worries for anything like that.” Rarity patted Sunset on her shoulder, then stood to finish removing her sweaty clothes.
“Yeah, I know all that, it’s just… frustrating, you know? Back in Equestria, I was so used to using my nose to smell all kinds of things, to identify who it was, what it was, and even find a good lay. Now, most everything is broken into three categories: Good, bad, and really bad.”
Rarity, with grace fit for a lady, put on her bra. “Well of course, that’s how it is here. We only strive for the best of smells, and most of those are pleasant and artificially made. Save for a few flowers, but even then we had to breed them into submission of the perfect smell.”
“No, seriously, can we go back to what she meant by mounting?” Rainbow asked, slipping on her shorts.
“No, I’m afraid not. You see, we’re trying to help Sunset with what is bothering her.”
“Yeah, and what exactly is bothering her?”
“These smells!” Sunset shot her hands up in the air towards the ceiling lights, then let them fall gracelessly to her stomache. “I just don’t understand any of them. I thought I had some figured out, but every time I come here-”
There was a sound of a locker slamming closed, bare foot steps walking along the tile floor. Both Rarity and Rainbow looked curiously off to the left, while Sunset ignored it, sitting up finally, and motioning to remove her top.
“It’s just, I’ve been coming here for as long as I could remember since leaving Equestria, and the smells always threw me off. I don’t get it.”
Then Sunset removed her sticky, sweaty shorts, showing nothing but bare skin.
It was at that time the mystery foot steps walked into view, causing Rarity to gasp and Rainbow to sigh with dejection.
“Good grief, what is that smell!?”
All three girls looked to Thunderlane, standing in the room naked, confused, and slightly agitated.
“Oh dear, we’re in the men’s locker room again, aren’t we?” Rarity asked.
“Oh, right…” Rainbow said.
Sunset sighed, hiking her pants back up and grabbing her gym bag to find the ladies locker room. “Oh, that’s probably what it was. Damn do I need to get laid.”
