Bring back the huge 'uns

Stacey asks "Are you sure don't want them even bigger anyway?"

"I don't know, I kinda like...", you start to stammer.

"As big as in Thick Chicks on Dicks 2?", Stacey interrupts you cheekily.

"What, how do you know about..."

"You really ought to learn to hide your porn stash better, Finn", Stacey sneers at you.

Wow, she sure is frisky and confident.

"Fine, but how about your back...?"

"Just write 'no back pain' with the marker, isn't that obvious?"

You pick up the marker and scribble "NO BACK PAIN" in Stacey's back. After you're done, she grabs the marker and crosses out the "DD" on her breasts. They promptly return to her natural size. Then she writes "K cup" on her breasts, saying "That should be about correct". Again her breast starts expanding rapidly until they're bigger than her head.

"And... my back is fine! How do I look?" Stacey asks.

"Huge!", is the only word you can produce to describe her.

"I wanna see myself", Stacey says and gets up, nearly falling on her face from the unusual frontal weight.

"Amazing!", she gasps. "But it's still not quite right, is it? I don't look like a thick chick, I look like a skinny chick with huge gazongas!"

Stacey pops off the cap from the marker again and writes the word "CHUBBY" on her stomach, thighs and buttocks. They all grow simultaneously, gather fat from nowhere and stopping when she has a fully rounded body that fits proportionally to her enormous natural looking boobs.

Your jaw drops. She looks exactly like the main actress from your favorite BBW flick, only more beautiful since she retained her young skinny face that you've grown to love.
