"You are just flesh and blood, like the others!!!", Fiona yelled with her first attack, trying to sound confident. But her first very angry attack just hit Kathryn upper tight. Because the 'little vampire' was not able to reach anymore while the ashblond was standing. Fiona fist not even scratched a single scar into the steel hardened muscles of Kathryn's long and powerful legs. But exactly these legs should be the next thing that Fiona should feel.
After some more attempts to attack Kate, the giant huntress finally had enough. She dodged one of the tiny hits easily and finally go into the offensive. A quick spin, a few steps and a mighty, single blow of those godlike legs and Fiona was flying. Hurtfully screaming, the redhead fell to the ground shortly after, imprisoned by Kate's strong thighs. A rather short and simple fight, but the show wasn't over yet.
After Fiona seemed beaten, Victoria was coming out of her hiding spot, stepping right next to her former student with a victorious smile. If the blonde just was more careful. When the mage was sprinting outside again, she just loses the blue potion on the way, but without noticing. But there was one who noticed it.
"I think she had enough.", Victoria said, before Kathryn smiled also: "Seems so. Some last words, Fio?"
"Yeah. You should take better care of your stuff!", the redhead smiled and used the carelessness of the two too grab the potion and just swallow all of it entirely. And so the catastrophe was about to happen.
The even more powerful potion set in as fast as the last one. But on top of this, it seems that the potion combined itself with the one Fiona already taken and her own magical vampire blood. A combination so powerful that the out coming growth was behind words.
First the redhead was struggling between Kathryn thighs because she was threatened by it, but now she seemed to enjoy it, closing her eyes and started moaning as this extreme growing sets in. Kate tried to end it and pushed her legs together, but it was too late. Now it was Fiona who pushed, and that even without doing something, but only her growth. Her remaining clothes, defeated by a boob grow that even put Victoria to a shame. But also everything else expanded rapidly as muscles formed, and her body becomes more of a goddess than a human, or vampire.
The growth finally lifted Kathryn up, and that even while Fiona was still laying on the ground, just using her leg to carry Kate upwards like she was riding the redhead thighs. The growing just doesn't want to stop. It continued and continued. Fiona's gigantic boobs finally passed Kathryn face, while every single of these mountains must be twice the mass of Kate's entire being. And as the growth finally reached its peak, the small road of the village was no longer fitting the giant vampire. So she stands up and embrace the final push towards the sky as the power lifts her up to ~55m in size. (~180f)
"I'M A GOD!", the redhead yelled with a voice that mighty that even a part of snow makes itself loose at the near mountains. Now Fiona wasn't any longer a woman, or a vampire, or even a giantess. She was a power of nature.
And as such, she just kicked little Katy with a wimp of her might. The huntress not only reached a quarter of Fiona's height and so was defeated in a single blow. Now it was Kathryn that flied, but much more far away, and down the cliffs of the coast. She fell into the ditch and was beaten for good.
But who would stop Fiona now, the ever more growing force of nature, if not Kate?
