(1) Scootaloo sat at the edge of the pool kicking her legs back and forth in the water.  
As she did, the girl closed her eyes and focused on the strange wobbling sensation coming from her chest.  
It was a strange feeling to say the least.  
She supposed she would get used to it but it would probably take a while.  
Certainly the changes the teen had experienced over the Summer had happened so quickly that she was still a bit disoriented.  
Thinking back to the end of the school year she remembered shooting up several inches.  
Suddenly, she had gone from one of the shortest kids in her class to one of the tallest.  
Not that she was complaining!  
Training with Rainbow Dash had become much easier with her longer, stronger legs.  
Then school ended and Scootaloo found another part of her body getting in on the puberty act.  
Her breasts.  
It was funny, she didn’t think of them as ‘breasts’ anymore.  
Breasts were something that almost any woman had.  
You could hide them under a sweater or a thick shirt and walk around without drawing too much attention to yourself.  
Scootaloo sighed as she opened her eyes and looked down at her extraordinary torso.  
No, the twin glands barely being contained by her overstretched bikini were at the very least ‘boobs’, although calling them ‘sweater stretchers’, ‘bazookas’, ‘juggs’, or even ‘tits’ wouldn’t have been inappropriate either.  
Over the last few months Scootaloo had gone from mosquito bites to mountains, each jumbo jubbly growing to a size quite a bit bigger than her head.  
They weren’t just big, they were full too.  
Despite their enormous girth, her chest rockets stood proudly off her ribcage.  
When she walked around topless her torpedoes would bounce enthusiastically, the soft flesh jiggling wildly.  
Then, when she came to a rest, they would snap back into a fulsome teardrop shape that proceeded her by well over a foot.  
Ms. Fluttershy had told her that her pegasus magic helped make them buoyant and lighter, for which she was glad.
 

 
(2) It was actually Fluttershy that suggested that to Rainbow Dash that they have a little getaway with Scootaloo.  
Fluttershy had gone through this before when her own gigantic chest came in and confided that it was one of the reasons she came to Ponyville all those years ago: the anonymity of being in a new place.  
That had led to Scootaloo, Fluttershy, and Rainbow Dash heading out to a beachside resort that Rainbow knew from being a Wonderbolt.  
It had been a fun distraction for Scootaloo and it gave a chance for the two older women to teach her a thing or two about her new body.  
Fluttershy had shown her how to handle her boobs.  
How to walk, how to keep from bumping into things, how wash them properly. (That had been only slightly awkward.  
Fluttershy had been so kind and open with her fellow big boob bearer that Scootaloo had even opened up with more personal questions.  
One night, in a giggling fit, the curious girl asked Fluttershy if she ever sucked on her own nipples.  
Blushing as red as a tomato, the busty woman admitted that she did on occasion.  
She even confessed that, sometimes, she would lay down, hoist both of her tits up to her mouth, and suck on both nipples at the same time.  
Scootaloo was shocked but intrigued.  
That night in bed she followed her mentor’s instructions and with a lot of shifting and jostling managed to wrestle her bloated baps up to her face.  
It had been a few weeks sine she had examined her nipples and they had gotten quite a bit bigger than she remembered.  
Licking each one in turn caused them to swell and stiffen until they were they were the size of her thumbs.  
Craning her head forward slightly she grabbed on teat with her teeth and chewed on it lightly.  
It felt good, but not quite how she expected it.  
Using her teeth, she tugged the turgid tip over to her other nip.  
Wrapping her lips around both cherry red targets she sucked down hard.  
Her nipples responded.
 
The burst of pleasure from her tits was so unexpected that she almost released them.  
Instead she doubled down, sucking harder than before.  
Jolts of ecstasy electrified her tits.  
Over the past few months as her breasts had gone from baseballs to basketballs Scootaloo worried that they were becoming too erotic.  
Now, as her pussy twitched in sympathy with her nipples, Scootaloo knew that was the case and she didn’t care!  
She continued to pull on the teats in her mouth, working her tongue in between the stiff nipples, biting them lightly every few pulls.  
At this point her slit was begging for attention but both of Scootaloo’s arms were occupied holding her boobs in place.  
Deciding to risk it, the randy girl dropped her right arm while keeping the suction up with her lips.  
Slipping her hand down her stomach she found her aching womanhood and gave it a hard stroke and came immediately.  
As orgasm ripped though her body Scootaloo almost cried out, but instead she clamped down on her pulsing nipples.  
She couldn’t be sure but it felt like they swelled even larger as she thrashed around on the bed.  
Exhausted and content, Scootaloo drifted off to sleep.  
The next morning, as she put on her bikini, Scootaloo hissed in discomfort.  
Her boobs were sore.  
She half expected it, with the way she had mauled her tits the night before, but the soreness wasn’t limited to her nipples.  
Both juggs were sore all over.  
Sure that the pain would pass, she went about her day.  
The next day the soreness had changed; her boobs felt tight and swollen.  
Her poor erect nips were flushed red and felt hot to the touch.  
Suddenly, Scootaloo recognized what was happening from previous experiences.  
Her boobs were having another growth spurt and compared to the previous times this one felt like a doozy.
