Scootaloo Springs Up

“FASTER! C’MON SCOOTALOO, PUSH YOURSELF HARDER!”

The shrill blast of Dash’s whistle rang through the air. She was standing at the finish line of the track, whistle in her mouth, stopwatch nestled in her breasts. The temperature had climbed into the eighties and both Scootaloo and Dash were soaked in sweat from their endurance day. Dash had gone first and completed her laps while Scootaloo hydrated, which also let them time each other for laps. Scootaloo was on her fifth and final one. Dash watched in anticipation as Scootaloo rounded the corner into the home stretch. She was barreling down the track as fast as she could, huffing and gasping with each step. Dash pulled the stopwatch out and, as soon as Scootaloo hit the line, punched the button.

“WHOO! You did it! Congratulations, Scootaloo! You broke your personal record by like, FOUR whole minutes!” Dash said excitedly, checking the notes on her phone.

“YES!” Scootaloo did a half-jump, and quickly resumed downing her bottle of water. In seconds she had drained it, and was cracking open her second.

“Glad I brought extra, huh?” Dash walked over and took a swig. “We’re done for today, so let’s head inside before it’s dark.”

“Mhm!” Scootaloo nodded eagerly, grabbing the water pack and strolling after Dash.

“Okay, that was great, Scootaloo, but I think you might have gone a little bit better on that run,” said Dash, as she walked into the house and kicked off her shoes.

“You think I should’ve had more water?”

Dash shook her head. “No, Scoot, it looks to me like you’re… what’s the word for it… Constrained.”

“My clothes?”

“Yep.”

Scootaloo looked herself over. In another twelve days she had grown three whole inches, putting her up to almost five foot-six. The T-Shirt she was wearing was tighter around the collar thanks to her growing body and enlarging traps. It was so tight that it was like a second skin, and the sweating made it even more so. Scootaloo’s breasts had continued to grow, putting her firmly into the C-cup range, and tented out the front of her shirt very noticeably. It also completely revealed her midriff, exposing three lightly defined rows of abs. Her widening hips and thickening thighs had pulled her shorts up so high they were clinging to her like spandex, and were stretched tight all the way around thanks to her plumping rear. Even her socks barely came up to her ankles now.

“But I like my clothes!” said Scootaloo.

“Bet you do, Scoot, but you’ve outgrown them,” said Dash, her eyes roaming over Scootaloo’s cut legs. “There’s a big difference between form-fitting and too small. Don’t tell me you like forcing your head through that tie-dye shirt you have on.”

Scootaloo sighed. “I don’t…”

“Nobody does. Listen, you’re getting close to my height now, so how about I let you have some of my older, kinda worn out but still okay clothes to wear? You can’t run in this stuff!”

“Alright…” Scootaloo peeled off her sweat soaked shirt, right in front of Dash, holding it in front of her like a dying pet. “I made this with Sweetie and Applebloom like, forever ago…”

“Right.” Dash blushed, looking Scootaloo over. She was going to have a figure as nice as she did soon, keeping this up. The sweat had soaked through to the straps binding Scootaloo’s burgeoning assets, and they looked like they were fighting to stay in those bandages, the two nubs of her nipples poking obviously through the tape. Her broadening shoulders flowed into her stronger looking arms, and her chest muscles were even developing well, the bigger pectorals pushing her growing breasts up and out, making them even perkier than they already were. Scootaloo now had a very tantalizing body and Dash wasn’t sure if Scoot realized it.

“Uh, this way,” Dash beckoned Scootaloo down to her bedroom, realizing that she’d been staring at Scootaloo a bit longer than was wise. Good thing Scoot had been lost in thought over her shirt.

“Okay, here we are. Buncha shirts and a buncha shorts I don’t wear anymore,” said Dash, pulling out clothes from a beat-up grey tub on the floor of her closet.

“These are nice!” exclaimed Scootaloo, examining the garments Dash had tossed her way. “These don’t look old. Most of these are good stuff.”

“Yeeeaah, they’re a little worn and faded in some spots. They should last you too. Also, the material they’re made out of won’t get you as soaked compared to the cotton tees,” Dash unfolded a bundle of her modified T-shirts, with rips going down the neck and also at the sides below her arms. “These oughta be okay too, even tho I kinda shredded them.”

“Cool! Thank you so much!” Scootaloo immediately threw on one of the plain white tees. They didn’t fit perfectly, a little loose around the stomach and a little tight in the arms, but otherwise, it was a good fit.

“No prob,” Dash tried to not look at the exposed cleavage. “We oughta get up and start lifting for today…”

“Okay!”

“Be sure to put all your old clothes away so they don’t mix with this stuff I just gave you. Putting on the wrong outfit and constricting yourself is no good.

“Gotcha!”

“Let’s go, Scoot.”

They both got up from the floor, Scootaloo bundling everything under her arm and leading the way. Dash followed closely behind, eyeing the outlines of Scootaloo’s back muscles rippling under her old shirt. It occurred to Dash that Scootaloo was getting really close to her height now. She was staring at the back of Scootaloo’s head. There’s no way Scootaloo was going to keep growing like this. Puberty had to slow down eventually. Right?

“Alright, Scootaloo, good workout today!”

Dash racked her thirty fives. Usually she picked her normal weight at thirty. Today though, Scootaloo had insisted her twenty two’s were no longer a challenge. The thirties had been perfect on the other hand. So, Dash had moved up five pounds and did more sets with less reps. Those weren’t a challenge challenge, Dash had told herself, but something she’d be moving onto anyway. Nonetheless, her arms were feeling the burn.

Scootaloo had already racked her weights, and was sitting patiently in her chair at the time. Arm-wrestling time. The boisterous girl was sweaty, but didn’t seem visibly tired from their exercising today. Dash held her breath for a split second. An extremely brief shadow of a doubt had just crossed her mind.

“We’re doing the run after this, right?” Scootaloo asked, stretching her arms and legs straight out, then relaxing them.

“You bet,” Dash said, taking a seat across from Scootaloo. “Right after this.”

They locked hands. Maybe it was just the workout, but to Dash’s eyes, Scootaloo's bicep looked just a little smaller than her own did.

One.

Two.

Three!

Dash went for the slam, only to be caught by Scootaloo resisting hard. She was holding her ground only a few inches away from the table’s surface! Dash clenched her teeth. She was so close! With some extra effort, Dash slowly brought Scootaloo's hand down to the table.

“WHEW!” Scootaloo stood up, shaking her hand. “That was awesome!”

“Yeah, it wasn’t a total landslide like usual,” there was a hint of concern in Dash's voice, despite her victory. “C’mon, let’s get jogging.”

“Last one to the door has to carry the bags!” shouted Scootaloo, slipping past Dash and charging up the stairs.

“We’ll see about that!”

Dash pursued Scootaloo up the stairs, hot on her tail.
