Scootaloo Springs Up

Dash checked her Wonderbolts watch for the second time in twenty minutes.

Usually when alerting Scootaloo to come with her in the past the girl would come running (or scooting) over promptly. Way in advance most of the time. This was before summer; before her exercise regimen had kicked Scootaloo’s metabolism into overdrive and transformed the tiny teen into a six foot plus amazon with a powerhouse physique bigger than she’d ever hope to achieve herself. Dash was now looking up to Scootaloo these days. Despite the shift in height, Rainbow knew that the girl still (metaphorically) looked up to her for guidance and inspiration. Scootaloo could be fifty feet tall and would still hero worship Dash.

Fifty foot tall Scootaloo. Dash felt butterflies dancing in her stomach at the thought. How big could this girl possibly get by the end of the summer? This morning Scootaloo was over six feet tall. That was big. Six or seven inches taller than she was.

The thought of a literal giant Scootaloo persisted for a little while longer. Dash stretched out on her lawn-chair and turned over to get some more sun on her front. After that quick dip in the lake she figured that working on her tan and catching a nap would feel nice. Her breasts wobbled and settled a few seconds after adjusting herself – the thoughts wouldn't leave her and she was starting to feel horny again.

Right as she was going to doze off she felt the sun's rays disappear. Dash groaned. It was supposed to be clear all day. Dash flicked her shades up and gasped at what was blocking the sun.

“Hi Rainbow Dash! I thought you were asleep!” said Scootaloo brightly.

“Oh my –Scootaloo?!” Dash looked up, and up and up at the towering teenager standing above her, wearing the most revealing bikini ever. Inches of titflesh spilled over the side of the bikini and then some. The canyon of cleavage on display bordered on obscene, and a good bit of dark areola peeked out around the cups of Scootaloo’s bikini. They were impossibly perky- sticking out thanks to her beefed up pectoral muscles. Despite their increasing size they didn’t hang low enough to obscure her rock hard abs. There was no doubt in Dash’s mind that she had been getting bigger throughout the day in both sheer size and strength. Dash realized she’d been staring at Scoot and cleared her throat.

“Are- how- When did you get so big?! How big are you now?!” choked Dash.

“Siiiince this morning and through the day. I’m 6'9" tall now, so I grew like 6 or 7 inches,” Scootaloo said with an idle tone, as if she were reading a train schedule.

“You’re like, more than a foot taller’n me now!”

“I know right!” Scootaloo kneeled down slightly. Even crouched she was looking down at Dash. “You’re so much smaller than me!”

Dash tried very hard to keep her eyes focused on Scootaloo’s face and not her huge, watermelon sized tits dangling pendulously in front of her. “Yeah.. just, wow. I think I should like, send my workout plan stuff to a magazine or something.”

“Oh! Before I jump into the lake,” Scootaloo reached one beefy arm over and picked up a bottle of suntan lotion. She squeezed half the bottle into her palm and began to rub down her arms, shoulders and abs in front of Dash. “Get my back for me.” Scootaloo handed the bottle to Dash and turned around, presenting the defined muscles of her backside. It was more of a command than a suggestion.

“O-okay,” Dash cleared her throat and began rubbing the creamy lotion onto Scootaloo’s broad back. Those rippling muscles were hard as stone from her delts to her lats. Each was so clearly defined that Dash couldn’t help but linger here and there to feel just how hard they were. When Scootaloo sighed happily from the sensations she flexed her back muscles and pushed backwards slightly into Dash’s palm. Using one hand was taking a longer than expected. Dash finished rubbing in the lotion with both hands until Scootaloo’s entire back was thoroughly covered.

“Thanks Dash!” Scootaloo abruptly pulled herself up and stretched. “Thanks a lot!”

“Do you even burn?” asked Dash, ogling the fetching heart shaped calves staring her in the face.

“Sometimes, but better safe than burned. It hasn’t happened much this summer because there’s lots of trees blocking the sun in the woods where we’ve been running,” said Scootaloo reclining into the other tanning chair. Her long legs placed her feet firmly on the ground despite being flat on her back. She pulled the cap she bought over her eyes. “I’m going to tan for a little bit then jump in the lake, 'kay?”

“Sure, y’know, whatever you want, Scoot,” Dash settled back into her recliner and put her sunglasses back on. Even though she told herself that she wouldn’t, every few seconds she’d glance over to stare at Scootaloo’s big powerful body. The rise and fall of her big breasts (bigger than hers by a lot) with every breath, those perfectly defined legs, the powerful arms that bulged with muscle even unflexed and the amazing ass that spread out underneath what was practically a thong on her big body. Dash ogled the dark areola that wasn’t fully covered by the bikini. With her areola and her puffed out nipples they stood off her breasts a good two inches or more. Lulled by the heat and entranced by the body of the amazon next to her, Dash nodded off.

Scootaloo yawned and stretched, smacking her lips. It was hotter than before she fell asleep. A quick check of her phone showed she’d been out for fifty minutes. To her left Dash still snoozed away –her head was tilted towards Scootaloo. This got a smile out of her. The bikini Dash had on was a perfect fit for her size. It was a bright baby blue and really showcased her big bust. Or, her relatively big bust to be more accurate. Scootaloo now had tits to rival royalty and she knew it. She couldn’t wait till tonight.

For now, she had to take a dip in the lake. The sun had moved and put Dash mostly in the umbrella’s shade. Scootaloo could really use a dip. She got up and slipped into the lake quietly. Her plan was to wait for Dash to wake up so she could exit the lake and walk towards her dripping wet. Maybe she’d break right there just from the sight of her incredible body. Scootaloo submerged herself under the lake and floated around with her head sticking out the water. The cool water was just what she needed.

“Hey, Scootaloo!”

She turned her head around and swiveled. Sweetie Belle was approaching. holding a dark blue beach bag and wearing the most amazing one piece bathing suit that she’d ever seen. It was a royal purple number, with a diamond cut out revealing her belly button and another, slightly larger diamond revealing Sweetie’s creamy cleavage. It hugged her generous curves so, so tightly, and showcased her amazing body in a way that only something Rarity could design.

“Is that yours or your sister’s?” asked Scootaloo, realizing she’d been staring.

“It’s one of Rarity’s.”

Sweetie Belle approached the shoreline and slipped out of her flats, turning around and opening the beach bag to put them inside. There was a huge diamond cut out the back of the suit, from the bottom where the subtle swell of her ass was to the top by her neck –it exposed nearly every inch of her smooth, white back.

“You look dead sexy in that thing,” complimented Scootaloo with a low whistle.

“Stop, it’s too tight on me,” Sweetie Belle blushed, a smile creasing her face. “Rarity’s out of town so it’s not like I could get her to make me a custom something.”

“I like how tight it looks on you. You’re a total knockout.”

Sweetie Belle flushed an even deeper shade of crimson and gracefully dipped into the lake. Scootaloo paddled herself over slowly despite her feet touching the bottom halfway over to Sweetie. When they swam over and met face to face, they both stood up. Scootaloo rose up and above Sweetie Belle, who found herself staring up at Scootaloo’s glistening, overstuffed bikini, water running in streams off her body and dripping into the lake.

“Do you really think I’m… sexy?” asked Sweetie quietly.

“Yeah, I do. For a while now,” Scootaloo bent over slightly and, as if she were lifting up a kitten, picked Sweetie Belle up under her arms and lifted her in the air so they were eye to eye. “And I know you think I’m sexy.”

Sweetie Belle dangled in the air, completely supported by this titan of power. Her calves were just above the waterline she was lifted up so high. Sweetie curled her hands around Scootaloo’s tensed forearms and moaned lowly. Scootaloo had her thumbs pressed right below her breasts and it felt amazing.

“I dooo… oh gods. Scootaloo. You’re like,” she bit her lip and scanned her massive friend, “you’re like, everything I find attractive rolled into one person and it’s you, Scoot. I didn’t think it would be but, please, I need you right now before I explode from-”

Scootaloo leaned forwards and kissed her hard on the lips. It was electric. Sweetie Belle melted in her grip and wrapped her legs around Scootaloo’s midsection, squeezing hard against her. This was everything she had wanted. Since she had first laid eyes on her at the restaurant, an opportunity to see Scootaloo again was stuck in her mind. The size, the strength, the bountiful breasts pressed against her comparatively smaller own. It was intoxicating.

“OOH! Oh my-holy shit Scootaloo!” gasped Sweetie, breaking her frantic kissing. Scootaloo palmed Sweetie’s cushy rear with one hand and slipped her hand through the diamond cut around her bathing suit down to her pussy. Her finger felt huge! Sweetie convulsed in her grip, leaning backwards and shaking from the size of the digit penetrating her. When Scootaloo slipped another finger into those hot wet depths Sweetie all but screamed before biting her knuckles.

“Why’re you doin’ that?” asked Scootaloo, wiggling her fingers around and delighting in the reaction.

“Don’t –AH!” Sweetie squealed into her fist. “Want to wake up Rainbow…”

Scootaloo glanced behind to where Dash was still sleeping under the umbrella.

“Doesn’t matter if she hears. Maybe she’d even be down for a threesome!” she punctuated that by slipping a third finger inside Sweetie’s tight little cunt.

“OOOHFFFnnnnnnn-“ Sweetie Belle came again, hard, biting into Scootaloo’s shoulder to muffle her cries. There was so much stuffed inside her right now, the sensation was insane. Scootaloo was not letting up either –pumping her fingers in and out with gusto now as Sweetie pulsed and throbbed around her fingers. It was delicious –being able to pleasure her friend so easily, how she was completely enraptured by her new body, and how she was mewling in delight with her idol dozing so near to them on the show.

Five minutes in and Sweetie was rocked by her strongest orgasm yet, shaking and swearing and jabbering incomprehensibly. Holding on to Scootaloo wasn’t in her realm of motor control and Sweetie nearly fell back into the lake.

“You alright?” asked Scootaloo, withdrawing her fingers which were now thoroughly soaked in Sweetie’s warm juices.

“Awulgulah,” replied Sweetie Belle.

Scootaloo laughed, her breasts jiggling softly. Sweetie Belle exhaled loudly and rested her head against one of her massive beasts. It took a minute for her to get her senses together.

“That… was the second single most amazing thing to happen to me in my entire life… so far,” said Sweetie Belle, idly running her hand along the curvature of the huge heavy tit she wasn’t resting her head on.

“What’s the first?”

“You, by far,” said Sweetie, looking up at her intensely. “Just, oh my god Scootaloo. That was amazing. You’re so big and sexy and… everything.”

They stood in the warm lake water together for a few more minutes, holding each other in the afterglow of Sweetie’s sexual release and making out with each other deeply. Eventually they both slid down into the water to kiss face to face to alleviate the neck strain from kissing at that angle.

“I’ve got to go home,” Sweetie broke their kiss, swimming backwards towards the shore.

“How come?”

“There’s this music thing I have to do in the morning. Early. I need to be there to meet with this guy and-“

“It’s fine,” Scootaloo cut her off, “You’ve got to go do a thing. I’ve still got to go too. Dash might wake up soon anyway, she doesn't nap for very long.”

Scootaloo swam forwards and kissed Sweetie hard on the lips, taking her breath away with it.

“Are you going to… keep growing even bigger?” asked Sweetie tentatively.

“Yes,” Scootaloo replied confidently, eliciting an excited smile from her little lover.

Sweetie Belle walked out of the lake dripping wet. The bottom half of her bathing suit was twisted and exposed her pussy when she bent down to get her towel. Sweetie turned and blushed deeply when Scootaloo wolf whistled at the sight. As she left down the path Scootaloo followed the sway of her hips until she’d disappeared. Once she was gone, Scootaloo floated on her back in the lake and fondled her big tits. Man, life was amazing.

On the lawn-chair, a very wet and aroused Rainbow Dash watched in a daze, wracking her brain over the scene that just played out. She was more aroused than she’d even been in her life and it took every ounce of willpower to not touch herself.

The timer she’d set on her phone went off. It was time to wake up and go home. Dash made a big show of yawning and stretching.

“Hey Dash. Had a good beauty sleep?” Scootaloo asked brightly.

“Power nap,” corrected Dash with a grin. No matter how big Scootaloo would get, she’d still be Scootaloo after all. “Rarity takes beauty sleeps. Even wears this frilly thing on her face to block out light. Me on the other hand, heh, I can zonk out pretty much anywhere.”

“Mmm, yeah. I see whatcha mean,” Scootaloo swam towards the shore and walked over to Dash. “I’ve got a bunch of bags of stuff but I can help carry your other things. Did you take the chair with you?”

“Nah,” Dash patted the heavy metal bar. “I leave it parked here. Everyone knows it’s mine so you don’t have to take it if you-“

Dash trailed off when Scootaloo approached and openly gawked up at her. All the way up. Scootaloo had to be over a foot taller than her now. Now her eyes were level with Scootaloo’s shoulder. The bottom of her shoulder. This morning she was able to look her in the face at least. Over the course of a day she’d grown several inches taller. Every square inch of Scootaloo’s powerful, muscular body was on display and put her own physique to crying shame. Standing next to this incredible amazon, Dash felt positively tiny compared to her.

Scootaloo positively knew it.

“Are you sure?” Scootaloo lifted the metal seat up high in the air with two fingers with no difficulty. “Wouldn’t be any trouble for me.”

“Nuh- No! It’s totally fine where it is,” Dash said, her voice cracking, ”Summer's not over yet so uh, we’ll just leave it.”

“No problem, then,” Scootaloo remarked, dropping the lawn-chair with a heavy thud into the sand. “I’m actually pretty tired anyway. It’s probably the heat. Let’s split, Dash.”

Scootaloo turned around, raised her hands over her head and stretched, her muscular back rippling and flexing. The small bikini top strained against her bulging breasts. Not that she was actually tired. It was purely display.

“Sure. Let's split,” Dash said meekly, eyes taking in all she could. “L-Lead the way.”
