As much as Veronica knew there was almost no way of stopping Rachel now, she focused all of her strength into this last attack, hoping to overcome her daughter and retrieve the belt.
"You leave me no choice, I'm sorry." She declared as she dashed towards Rachel, stopping right in front of her. She rose her fists, gathering every last drop of power in them and punched Rachel's midriff as hard as she could with incredible speed. Every regular human would have been torn in a million pieces by such force, even superheroes would get hurt badly from this. But for Rachel it was... merely a tingle on her impossibly dense abs. Maybe even less than that, it was hard for her to tell.
While Veronica gave it her best, Rachel looked down at her struggling mother, shaking her head with disappointment.
"Mom, mom, mom... I really thought you'd understand me just now, but I think you don't leave me a choice here either, so..."
Calmly, Rachel brought up her right arm, just about where Veronica's head was and casually flicked her index finger against her forehead. What seemed to be a mere flick of Rachel's hand was something completely different for Veronica. It felt as if an entire planet had just been thrown at her at high speed. With what could be described as a sonic boom, Veronica was catapulted right back into the gap in the wall she just came from, only now she made that gap way longer than before. She should be glad that she was still conscious. If Rachel had put in the same amount of force her mother had just used, she would've blown off her head easily.
"Pff, corrupting belt." Rachel said to herself as she reached down to the belt. "As if that would be true!"
She pressed the buckle yet another time, the red light emitted, shortly followed by another spectacular growth. Her height increased by three inches, leaving her at 7'8". Her boobs and ass grew to even greater orbs of pure sexiness while her muscles aimed to strike utter fear instead. They expanded some inches all around while getting that much denser, and therefore, stronger. With the strength of 250 Veronica's in her, her body felt great, and it showed.
Meanwhile, her mother was on her way back to the basement, flying through the tight gap in the ground, still recovering from Rachel's astonishing feat of strength.
