"You don't like this size?" asked Joe. "Fine, then. I'll change you again."
Again, Melanie rapidly grew larger. Her legs stretched out long and thick like tree trunks as her whole body grew in scale. This time, her breasts and her ass swelled well out of proportion to the rest of her growing body. When her growth abruptly stopped she looked down at a pair of gigantic breasts bouncing in front of her, which she couldn't even see past to look at her body below. She looked behind herself to see she had an equally gigantic pair of buttcheeks and hips to match her tits.
Bellow her, Joe just smiled at the marvelous thing he had created. His sister Melanie was now 11 feet tall, naked, and showing off an exaggerated hourglass figure.
She glared down at Joe.
"YOU LITTLE ASSHOLE!" she shouted, her voice sounding deeper and louder than before, almost mannish. "LOOK AT ME." She gestured to her huge tits. "I'M A FREAK! A GIANT FREAK!"
"I think you look beautiful," said Joe, but she didn't appear to agree. "That body is very sexy. And, anyway, you said you didn't want to be as big as you were a minute ago, so I made you a different size. I made you bigger. You don't like it?"
She took an angry step towards him, heavily stomping her giant foot on the ground near him, which would have been intimidating if all of that moving hadn't started her ass and tits jiggling out of control. Joe suppressed a chuckle. Even though he had complete control over her body size and shape, he had to be careful. Melanie was now twice his size and capable of doing some real harm to him if he let her.
"You listen to me," she said after her body had calmed down its jiggling. "Either turn me back to my normal self now, or I kick your tiny ass down the street until you beg for mercy."
She rested her hands on her huge hips and stared at him, furiously.
"Well," she said. "Which one will it be?"
