Growing Contest Overdrive!

"Ha!" Serenity scoffed. "You're not stronger than me, you purple pussy. You never will be!" Serenity smirked and prodded Ultra's chest with her finger. Ultra slapped her hand away and stomped her foot in anger, shaking the ground and cracking the sidewalk. People were already giving them a wide berth, but now they started to turn and leave.

"I'm stronger than you, and BIGGER!" Ultra shouted, performing a crab flex as her muscles bulged and swelled to even larger proportions. She flexed even harder, and they began to grow, pulsating and engorging, then her entire body began to grow, stretching upward until she was more than double Serenity's height, roughly 25 feet tall.

"Peh, big deal. I can do that too!" Serenity said, waving her hand dismissively. Serenity clenched her hands together and flexed every muscle in her body. They bulged, rumbled, and then swelled like they were being inflated. Then, just as Ultra did, she began to grow taller as well. Within seconds, she reached the same height as Ultra, and then she began to rise even higher. Ultra was cast in shadow and stepped back as Serenity towered twice her height at 50 feet tall. "Well, well, well... how's the weather down there, shrimp?" Serenity laughed.

"Ugh, you..." Ultra gritted her teeth and clenched her fists.

"Girls, girls. I can do that too." Luft interrupted as she stepped forward. Luft closed her eyes and focused on the nano-machines in her body, switching them to overdrive. Her muscles quivered and engorged as she grew bigger and taller. Within moments, she towered over both of them at 100 feet tall, looming over Serenity and Ultra, casting both in her shadow.

"You too?" Ultra stepped back again, gawking.

"You cocky..." Serenity growled.

"See? We can all do that, so..." Luft started to say.

"Oh yeah?! You won't beat us!" Serenity and Ultra shouted in unison. They both began to flex and grow again.

"Oh boy, that didn't help..." Luft muttered as she placed her hand over her face.

A short time later...

"Yes! I told you I'd win! I'm the biggest! I'm the best!" Ultra bellowed as she flexed both of her mansion-sized biceps. They bulged as she flexed them, and her breasts bounced up and down as she flexed her pecs one after the other.

"Yeah, yeah, I'm still stronger than you." Serenity said as she leaned against a building, carefully examining an expensive-looking sports car with a flame-pattern paint job. It looked like a toy in the palm of her massive hand. "Sweet colors." Serenity muttered as she admired the glossy paint.

"Uh, I think we went a bit overboard." Luft sighed. "Still though, who knew we could get this big? I wonder how far we can really push it?" Luft stood next to another building, comparing her height to it. She moved her hand from the top of her head to the skyscraper, measuring how much taller she was than it. "Well, at least we know we can fight a kaiju if one ever shows up..."

On the ground, most people ran away in fear, though a few men and women stared up at them with awe, and maybe even envy.
