Josephine gasped out loud. Her muscles bulge, veins burst to the front, pumping more and more blood around her body. She starts to pant as her hight increases and her body starts to spasm but with every spasm, her muscle's increase, she could hear her heart pumping in her ears. So strong it was making her body jolt in time with her heart beat. Each pump her muscles grew and slowly her skin darkened.
Her muscles tighted together, coiling tighter. Pumping bigger. Her boobs started to increase along with her muscles. Soon a deep pleasure hit her every time her heart beat.
"Uh, uh! Uh! Uh! UH!"
She couldn't contain it. Josephine trembled then watched as each pump of her heart her hands grew bigger and bigger, her nails longer and longer, reshaping into claws.
Her skin darkening, turning black. Josephine tried to contain it but it was clear the pain but deep pleasure she was feeling was overwhelming her.
"UH, UH! grr...UHHH!"
She started to feel angry and horny? Her teeth sharpened and she couldn't hold back a animalistic snarl.
"GRRAGHGRRR!"
The rage and pleasure Josephine was feeling proved to much as she through her head back and screamed.
"I...UH! cant...C-control my-Uuh! AAARG!! AAAAAAAAARRRRGGGG UUUH RAAUGRRRRRRRRRRR!!!!!!!!!!!"
That's when her transformation really picked up as Josephine's eyes tured a dark red, her pupils disappearing as her humanity disappeared.
