Katie gets her turn

With a mere thought, Katie went back in time. Riley was back at 7'5", and Heather was at 7'8". Katie decided to make it so they were as big beforehand as they just were at the end.

Starting with Heather, Katie used her powers. Heather started to grow, and this time, her clothes couldn't keep up quite with her. Her bra quickly snapped off, and her panties got destroyed. Passing eight feet tall, Heather could easily touch the ceiling. She stopped at 8'1", fully naked. She looked down at Riley and smiled.

And then Riley grew. Her breasts popped her bra off, and her panties got torn to pieces. Her breasts were huge, bigger than medicine balls. She quickly passed Heather's height, and for fun, Katie made Riley grow more, to 8'5" - three feet taller than she was before Katie started messing with reality. Then Katie changed reality. Heather looked like she was wearing a bra and panties that actually fit her, but they looked like they were made from shower curtains. Riley had panties that were torn, barely on at all, and her chest was... bare.

"Just so you know, I WAS wearing a DD bra, but my growth caused it to snap off." Riley said.

"Wow, Riley! What were you this morning, eight foot one?" Heather said.

"Yeah. I'm growing so much! I'm the biggest girl in the world! Two weeks ago I was only six feet tall! In a few more weeks I'll be so tall I won't even be able to fit in here anymore!" Riley said, jiggling her boobs.

"I can't believe what teenagers are taking these days... and Riley, why don't you put a bra on?" Zoe said.

"Pfft. When a girl is this pretty, you don't hide the goods!" Riley said, winking at Matt.

Well, Katie had had enough. It was time for her to grow. Suddenly, she started to inch upward. Her breasts started to enlarge, filling up her B-Cup bra past its limits. Her butt grew firmer and rounder, and started to swallow up her panties. Katie quickly passed Zoe's height, and then her bra snapped off, leaving Matt to stare at his girlfriend's amazing body. And then Katie's panties snapped off. She turned around to give Matt an amazing view of her butt, which was also still growing. Soon Katie was higher than Heather's breasts, and to Heather's surprise, Katie grew taller, and eventually surpassed Riley as well. Katie decided to keep growing. By now her once small breasts were larger than Heather's, and as Katie passed nine feet tall, they grew bigger than Riley's! Katie was growing more and more beautiful. If she was of normal height, nobody would be able to look away from her perfect boobs, butt, and slim waist. But then Katie encountered a problem. Her head hit the ceiling, and she was now ten feet tall! Matt got a raging boner just from looking at his goddess of a girlfriend (well, considering Katie's abilities, she really was a goddess). Katie smiled, and then changed reality.

She wasn't wearing much, but she had the cups of her old B-Cup bra attached to some rope, so the cups barely covered her nipples. Katie was wearing nothing down below, but considering her size, it wasn't like there was that much she could wear.

"Ugh... I don't know why I even bothered coming here. There is obviously something in the water affecting girls!" Zoe said.

"Wow, Katie, you're like... huge!" Heather commented.

"You know, ever since you found that radioactive meteor, you've been growing like a weed! A weed with Super Extra Powerful MiracleGro! And now, when ever someone speaks about your body, you grow! Speaking of which, it looks like your vagina is level with Matt's face!" Riley said.

Katie looked, and then walked straight up into Matt's face. He was shocked that Katie was standing up and he was staring straight at Katie's vagina!

With that, Katie's head hit the ceiling, even though she was stooping down. Her frail makeshift bra quickly snapped.

"Uh, guys... maybe don't say so much about my body! I don't have a lot of room here! Katie said.

"Oh, come on! Wait, how about we talk enough to make you burst through the ceiling? But man, your butt is so big! Imagine if it was bigger!" Riley said.

With that, Katie's butt did grow bigger, and Katie's neck was **** to the ceiling.

"Hey, Katie! Her breasts are absolutely huge for a eighteen year old! Bigger than the biggest porn star!" Heather yelled.

Katie's breasts enlarged even further, and she was grew big enough that her shoulders were at ceiling level. Cracks started to appear.

"I can't believe your vagina is going to be taller than me in a few minutes..." Zoe said.

That comment gave Katie a big push in growth. Her back pushed into the ceiling, and then it gave way to Katie's growing figure. Now Katie stood up to her full height, her bouncing boulders above the roof of the building. Passerby looked at the young goddess in all of her beauty. Zoe looked, dismayed, at Katie's vagina above her.

"Well, Matt, you can start to judge who's the biggest, but I think it's pretty obvious." Katie said, looking down.
