When some mares puff up to their new rubbery form in Rubberquestria, then puff UP, and immensely so. And then there’s the case of Fluttershy, who had been hiding in her cottage all this time during these events until finally, she decided to finally swallow her fears, and exit her cottage to try to visit her friends. And she did indeed find them….although by then, both Rainbow Dash and Twilight Sparkle easily towered over her as mini-giantesses and such shiny, rubbery ones too with goddess-like figures. A session full of lewd and puffed up antics later with the two of them, and Fluttershy was also beginning to puff up and UP like the others. Although unlike those before her, for whatever reason, something about her own body (or just pure dumb luck) caused her to puff up a LOT more than the others did. And for her, she was now a grand 15 feet tall, and more hugely stacked and curvy and BIG than those around her. Unfortunately for her own lower clothing, such did not survive the rapid inflation, so she’s going to now be walking around without such until she can get proper stretchy clothing on down there to cover up there.
 
One thing’s for certain though: something did change within Fluttershy after that, and from the sultry look in her eyes, it seems like she’s REALLY liking both how she looks now, and also who she sees before her. Still, do be careful when around her….both for obvious reasons for being gentle around such a gentle mare, and also because she may not be gentle to you if she has her way with you…especially if like other ponies, this new form ends up unleashing all of her pent-up sexual frustrations, needs, wants and desires at once within her in such an intense rush. And with Fluttershy, she likely has a LOT of that to spare to let out and go wild with on whoever she finds…which could easily be you if not careful.~
