Flitter Outgrows Her Sister

“You really don’t have to come you know,” said Cloudchaser as she fixed her hair in the mirror.

“Nah, it’ll be fun!” replied Flitter as finished off her makeup.

“No, I mean you actually really don’t. A plus one isn’t required.”

“So you’ve told me. But you know I can’t pass up the opportunity to meet some of your friends. If you really didn’t want me to go with you then why’d you bring it up?”

“It seemed like a good idea, but the more I think about it the more I just feel like it’ll be super awkward. It’s all going to be athlete talk and you’ll look and feel out of place. Why don’t you just sit at home with a book or something?”

“I’ve already got myself all dressed up so if you really felt that strongly you should have told me. Too late now.”

“Yeah. Too bad your dress looks like it does.”

Flitter put down her mascara. “What’s wrong with this? This is my usual ‘fancy going out to a nice place’ dress.”

Cloudchaser stopped fiddling with her hairspray and turned to her sister. “Is it? Well I don’t know what you’ve done with it because it looks pretty bad.”

Flitter played innocent, but she knew that Cloudchaser saw what she had realized herself when she took it out of the closet earlier. It had only been a couple days since their little jog turned footrace but the changes continued to progress well. Perhaps not enough for her arrogant sister to take immediate notice, especially now that she was wearing heels, but her clothes had begun to protest her increase to 5’8.

Her dress was a light blue colour and was supposed to cling to her curves but now it did much more than cling as her body had lengthened and broadened. She kept finding herself pulling it down as her increased height and larger, firmer butt didn’t fit as well as it should under the already short hem. As much as she appreciated it showing more of her growing body it did give a poor impression of her taste in clothing as it bordered closer to slutty club wear than elegant formal wear.

The one part that did look much better though was her stomach region. The dress was designed to flow around that area to leave it open and reveal a small amount of her smooth torso. With her changes the effect was only improved. The increased height stretched the fabric to show more of her abdominal area and with her muscle increase it no longer looked soft, but instead had definition that you could see in the light. She could only imagine how her little abs would look in time.

“Really? I like it.”

“Of course you do. I’ll give you style tips another time, I guess.”

Flitter looked at Cloudchaser and as happy as she was with herself she couldn’t deny that her sister looked really good. She wore a classy red dress that had a low back and a high front allowing you to see her well defined legs and up top it framed her arms allowing for a good view of her biceps and strong back muscles. She looked even more impressive in six inch heels making her seem to be a towering six foot four and- oh dear she was staring at her again. Focus on yourself, girl.

“Nice trick with the abs though. Where’d you read that?”

“Hmm?”

Cloudchaser prodded Flitter’s stomach. “Those. You know, working out a bit beforehand to make your muscles more defined. Nice work. I don’t bother, but I guess it’s a good idea for someone like you.”

“Wow, ‘Chaser. I’m impressed. You’ve managed to insult everything except my face and feet so far!” She said it sarcastically, but she’d been a little surprised by her sister’s attitude toward her recently. There had always been a sibling rivalry that came up as teasing once in a while, but the past few days Cloudchaser been quite regular with the attitude she was giving her. Flitter could only assume that even if her sister had yet to really acknowledge the changes happening part of her must have noticed and been bothered. Or she was still very annoyed by being nearly beaten by her a couple days ago. She could see that remaining a sore spot for her.

“Oh well your make up is fine, don’t worry. You’ve always had a knack for it I haven’t. Really, how do you get that swoosh by your eyes so smooth?”

“It just requires some practice. Do you want me to do it on you?”

“Nah, I’m good. I’ll let you keep the cooler looking eyes. Might keep them from looking at your feet.”

While Cloudchaser had sexy scarlet pumps Flitter was wearing sandals. They were nice sandals, but they were still not entirely what one would expect with this sort of outfit. It’s not that Flitter had planned to wear something like this since she certainly had more than enough pairs to choose from. It was her sister who was the type to have just one nice pair and one workout pair. Flitter took pride in accessorizing, but earlier that evening she had found that the one downside to her increased size was her small shoe collection becoming obsolete.

She had tried several pairs that would work with what she had planned, but each were far too tight for her feet. Too narrow for her broader feet, her toes stuck out the front, and her heel slipped off at the back. In a fit of frustration she had even forced herself to try wearing a pair only for the thin, elegant straps to loudly crack apart after a few steps in them. It was upsetting to have something she enjoyed ruined like that, but at the same time she got a thrill she’d never felt before watching something that used to fit her so well be destroyed by her sheer size. She’d have explored it more if there was time, but had to instead hurry and settle for an old pair of sandals that had been oversized, but even now she could feel her toes on the edge and the straps digging into her feet.

“The heel broke on the pair I wanted and this was the only other one in the right colour.”

“Whatever, your choice. You need the bit of extra height when you can get it, but I’m not gonna tell you what to do.”

Flitter hid the smug smile she felt coming on. Cloudchaser was right since she certainly would get the extra height when she could. She was glad her sister agreed.

*****

Their walk together through town to the central building was done largely in silence. They had sniped at each other enough when getting ready that neither particularly felt like talking by the time they were out the door. After the short walk and cool evening breeze they felt a little better though, and seeing the banner that hung up outside the town hall made Cloudchaser giddy.

The building had been taken over by the Wonderbolts for the evening as they did a circuit around various major cities and towns. The point was to draw attention to their recruiting season, celebrate those that had made it to the final round and, more importantly, sell tickets to the big event. The Wonderbolts were such an important team that many were interested in seeing who would make it through the final trials and it certainly helped that it was made into a partial showcase of the current team’s abilities as well.

“Are you excited? Please, don’t be nervous, because I’m not nervous, but, Flitter, I swear, please just don’t embarrass me in front of them. I can’t afford to mess it up. Them liking me is part of the competition so please don’t be weird.”

“You’re the one practically vibrating so just chill.”

“It’s just important okay!?”

They stepped inside and found the large open room ringed by various buffet tables with well dressed people mingling with each other. Most Flitter recognized from town, but she was sure that others must have come from nearby for a chance just to shake hands with such famous athletes. Cloudchaser left her briefly only to come back with a bolt shaped pin for on her dress which she took to mean that the finalists were marked somehow. She had tried to tell herself that it was unimportant, but seeing that on her sister just burned her up. She made an effort to distract herself instead and fiddled with the contents of her purse to act uninterested in Cloudchaser.

She then scanned the room to see if anyone else made it in, but the only one she could notice was Thunderlane. Really? Him? She thought he was a bit of a doofus, but good on him. What was most noticeable to her though was the one person who was very conspicuously missing.

“Did Dash seriously not make it through?”

Cloudchaser shook her head. “She was easily my toughest competition too. But you know how she is; made it to the third round then slept in and missed it. She’s probably at home still sulking.”

Flitter was about to say something more when Cloudchaser leaned down to her and started nervously nattering in her ear. “Okay shut up it’s them so don’t say anything, okay? Don’t screw this up for me.”

Approaching them were two people that Flitter could immediately recognize. One with bright orange hair that stuck up seemingly without the aid of hair gel and the other with wavy navy coloured hair that was almost certainly not combed since he got out of bed that morning and yet somehow still made him look handsome and stylish.

“Oh well hello there! It’s so nice to see you. Love the dress, Spitfire. Very good taste!” said Cloudchaser with a laugh that creaked just a little.

Spitfire smirked as she looked between their two dresses. By sheer chance the two were wearing one of the same colour and style.

“I take it that we both shop at the same place in Canterlot, eh? Sorry Rookie, but you’re gonna have to change.”

Cloudchaser hesitated to react until Spitfire laughed at her joke and only then did she follow suit. Flitter wanted to roll her eyes, but instead continued to smile politely at her sister’s side. Even if she had lost out physically she was much more adept socially and almost felt bad for Cloudchaser’s lack of innate ability when it came to this sort of thing. She’d cut her some slack.

It also helped that she felt like she had to impress these two. She felt her heart beat a little faster looking at them. Just Spitfire’s legs alone were more than enough to get her attention with their defined muscle along their significant length making her just want to hug them and not let go. At 6’2 and looking looking like 6’5 in her heels she enjoyed looking up at the gorgeous woman.

Spitfire nudged her companion. “Finish your mouthful of pie and stop being rude, Soarin.”

He gave an earnest attempt to respond, but only succeeded at mumbling incoherently through his full mouth. Not that Flitter really minded since she was happy enough to just look at him. At 6’6 and covered in dense muscle it looked like his suit was close to bursting. What seemed even closer to tearing though was the bulge in his pants. She could only imagine what he was packing under there, but tried to save those thoughts for another time as she looked expectantly at her sister to say something. Looking at her eyes, however, it seemed that she had failed to file away those same dirty thoughts.

Fine then. If her sister wasn’t going to be polite then she would.

“Hi there, I’m Flitter. I’m Cloudchaser’s-”

“-she’s just my little sister!” she said with a forced laugh, “Just figured I’d bring her along, you know, see what it’s like to hang around with so many talented athletes like us!”

Cloudchaser would never just say ‘younger’ sister, would she? Always ‘little’ sister. There was even a bit of extra emphasis and bite in that one. Alright, fine, so much for being nice for the evening.

Flitter tried to think of a good way to strike back at her sister, but Soarin, having swallowed his pie, unwittingly did better it better than she ever could. “I dunno, looking at her I’d say it runs the family, huh? I bet you have some competition, eh?” he said with a friendly humour in his voice.

The effect was immediate with Cloudchaser’s smile faltering for a moment then tightening. “Oh nooo, I wouldn’t worry about that. She’s an alright amateur, but it’s not quite the same.”

“Oh I’m not so sure, ‘Chaser,” said Flitter, “I thought that race was pretty close the other day.”

Cloudchaser turned to her with a ‘why in the fuck would you bring that up right now of all times’ stare. The other two, for their part, seemed to enjoy the rivalry.

“Ooh, is she giving you trouble on the track there, Rookie?” said Spitfire, “Maybe you oughta get her to sign up next year.”

Cloudchaser laughed uneasily. “I-it was just a little jog thing. It wasn’t a big deal. I haven’t lost to her in years.”

“...Seven years...” Flitter muttered loud enough for them all to hear.

“What was that?” said Cloudchaser, leaning towards Flitter and narrowing her eyes.

“It’s been seven years since I totally beat you.”

“You didn’t beat me.”

“But I actually did.”

“Arm wrestling isn’t a sport, so it doesn’t count.”

Flitter cocked an eyebrow and gave a smirking sidelong look to Spitfire and Soarin. “Can the experts weigh in?”

The both nodded in agreement.

“Mmhmm, shport,” said Soarin through more pie.

“It’s true. We even keep track of wins through academy records.” said Spitfire.

“I had the flu! That has to invalidate it.”

“You were also thirteen and I was twelve which you seemed to think was fair until you lost.” said Flitter.

“Fine! You think you’re so great let’s do one right now! You can put that in your records then.”

“Ooh, I love your spirit, Rookie! Lemme clear a table for ya.” Spitfire and Soarin went off together to find a table for them to compete on.

Flitter froze. She really enjoyed getting Cloudchaser all fired up over nothing like this, but she hadn’t considered actually competing with her here. She was much improved from what she was just a few short days ago, but looking at Cloudchaser’s arms she knew she still wasn’t quite a match. It wouldn’t be humiliating, but it would be a loss. Unless...

She arched her foot up against the top of her sandal until she heard the small metal ping sound of her strap snapping undone.

“Oh, shoot. Give me a sec,” she said as walked off to the side and crouched down to fix her shoe. Cloudchaser ignored her as she did so, still too unreasonably upset to do much more that stretch her arms while the other two moved a table in from the perimeter of the room.

With no one paying attention to her she opened her purse and fished out what she needed. The headband. It would look so stupid and obvious to wear on her head, but she hoped that looking like an idiot with it on your forehead wasn’t a requirement for it to work. She twisted the band around to make it a smaller loop then lifted her foot and slid it up her leg until it rested high on her thigh like a garter. She had a moment to ensure that it was hidden by her dress when a wave of energy hit her. Oh yes, this was working just fine.

She stood up resolutely with a new vigour she hadn’t had before. She walked over to the table that had been cleared and looked at Cloudchaser with a confidence that her sister was not used to seeing. That didn’t deter her though, and she faced Flitter with her own look of determination. She put her arm on the table and Flitter grasped it.

Spitfire reached out and held their clasped hands to keep them steady in the middle. Cloudchaser certainly looked like she had the advantage just from the difference in bicep size, but it was close enough that it didn’t seem like a sure thing.

“You two ready? Okay. 3... 2... 1... Go!”

As soon as she took her hand off the two began to go at it. Their muscles flexed as they both put all they could into bringing the other’s hand to the table. They grunted and their faces tightened in exertion. If Cloudchaser was surprised by how well Flitter was holding out she certainly didn’t show it. Her mind was too focused on winning.

Still, as much as Flitter tried, her arm began to be pushed back. She still had that familiar warm feeling throughout her body and her muscles burned in that way that felt so good, but it wasn’t enough. It almost angered her. After all this and she was so close but still not yet there!

Then her arm stopped descending. The two held this 45 degree angle for a few seconds, arms quivering as they stalemated. Flitter took her eyes off their hands to look at her own arm. Her bicep had definitely not looked like that before. She shifted her position and found that feet now felt uncomfortable from the sandal tightening around it and her toes resting just past the edge of it.

She could do this now.

Her grimace of effort turned into a smile, strained as it may be, and Cloudchaser’s arm began to be pushed back. It was slow, but it was happening. Flitter barely paid attention to the few whoops from the others who came to watch since her eyes were fixed on Cloudchaser’s face. She didn’t want to miss the mix of emotions that kept flashing across her. Surprise, then shock, then anger, then panic as her arm went past the midpoint and began to fall down to her side.

“Ow! Ah, stop!” Cloudchaser cried. She let go and withdrew her hand. “Ah, I must have pulled something the other day when working out. Something in my side just twinged.”

Flitter knew it was a lie. Cloudchaser had taken it easy the past couple days. Still, it would be more fun to just salt the wound than humiliate her in front of her idols.

“That’s right. You have worked so hard lately. Sorry, that was totally unfair of me. Are you alright?” Flitter said as she approached and put a concerned arm around her sister. The others believed the honesty of her words, but Cloudchaser knew the mockery they hid. She glared at Flitter as she approached, but didn’t push her away. She couldn’t when she looked downward and became more concerned with how Flitter’s stomach area looked so defined all of a sudden.

They didn’t stay long after that. Cloudchaser made her excuses and the two left with Spitfire telling her not to overdo it before the final competition and telling Flitter to see about trying out some time. That last comment did not go over well with Cloudchaser who stalked off ahead of her sister as they walked home in silence.

When they walked through the front door of their home Cloudchaser angrily kicked her heels off.

“Thank you. Thank you so much for making me look like an idiot in front of them.”

“I dunno, you seemed to do that just fine without my help.”

She walked into the living room practically tearing her dress off. “I’m going to bed. I don’t know how you did that but it won’t happen again.”

“Are you sure about that?” said Flitter who followed in after breaking the straps of her sandals rather than taking them off, just to see that she could.

Cloudchaser whipped around to face her sister. “Yes I-” she paused and stared, “W-why am I looking you in the eyes?”
