"This song is hard!" Jill screamed playfully.

"You're right... this has to be the hardest song I've ever seen played on medium" Matt added.

"I think I'm getting the hang of it, but- Ugh, I think I set the strap too tight"

Jill wiggled around a bit and felt better, but something wasn't right she felt bloated all over and her clothes felt tight. She was too focused on the game to realize that she was slowly raising higher though. Every muscle on her body slowly growing as if it was absorbing the blue glow around her. It wasn't till she had activated star power that she felt completely euphoric and her brother realized that she was growing, her stretchy long-sleeve t-shirt and sweatpants hugging her more tightly every second.

"Jill! You're Growing!" Matt yelled.

After that Jill immediately looked down at her swelling breasts, speechless. After Matt spit out the growing bit, he was quite speechless as well. Jill's first thought was to stop playing and see what was going on, but something told her that the game was causing it and she continued to play, for some reason wanting more. She was about 5'7 now and glad that she didn't really need to wear bras, because her breasts approached the size of large C's. Her muscle's were about the size of a strong teenage boy and still pumping larger, since her shirt was small the building bulges could be seen after every pulse. Her legs and hips were also growing somewhat disproportionately to the rest of her body, her legs grew longer, and her hips grew wider, she could also feel her sweatpants digging into what was her nice little bubble butt.

She activated star power a second time and another surge of growth hit, filling her breasts to D's and having her shirt and pants reveal her bare calves and well defined abs. She was an inch taller than her brother now at 5'10. The song ended, her scoring with 4 stars, leaving her the size of a small bodybuilder/large fitness model. She couldn't get any words out, even though she was in joy.

"It's my turn." Announced Matt promptly.
