To Dan's horror the blast hit the bully squarely in the back!
The bully, called Michael, felt something warm hit him in the back but shrugged it off, tormenting his neighbour Max was too entertaining.
"Come on Michael, please give it back." Max jumped up again trying to grab the bag and barely missing. Michael laughed louder.
Then he felt a rumble. From inside of him. "Woah..." he said, wobbling on his feet a little.
Max stopped and looked up at his bully neighbour. He loomed above him usually, but he seemed extra looming now.
Michael started to feel warm and like he was pushing outwards, almost flexing. And then he began to expand.
Max looked up in horror. Michael closed his eyes and clenched his fists, clearly enjoying what was happening.
"Oh, wow... this feels amazing!" Michael said, his voice deeper than it was a moment ago. The bully was now passing 6 feet, now two feet above his victim.
"You're... growing?!" Max stuttered.
Michael finally opened his eyes and looked down. "Holy shit I am!!" And he still was inching upwards.
"I'm taller than my dad I think?" Michael mused out loud. Looking down he noticed that Max was almost waist level... that meant he was closing in on 8 feet! He was gonna be the biggest boy... no biggest man ever! And it felt amazing!
He finally peaked out at 8 feet and 9 inches. He looked down at the shaking boy.
"Bet you can't reach it now, he said holding the backpack out again, now dangling a good 6 feet above the boys head. He noticed the backpack seemed to have grown too, and his clothes.
