Both women collapsed in pain, their eyes tearing up.
"Tiffany...what's...h-happening?" Katie asked, whimpering as pain lanced through her stomach.
"I..don't...I don't knowrrrrrr..." Tiffany replied, letting out a decidedly inhuman and deep growl.
The girls stared at each other in shock as slowly whiskers began to pop out above Tiffany's upper lip.
Katie began to panic, seeing her own hands beginning to blossom white fur along the backs, and feeling a tickling pressure above her lip as well. "No..." she whimpered, fighting against the changes, causing the pain to intensify.
When Tiffany saw her own fur blossoming, a lighter shade of orange, however, a smile crossed her face. A heat raced through her, and she began to tear at her clothing. "Soo...hot...rrrrrr..." she growled, tugging her shirt off, fighting to get her pants down as well.
Katie continued to struggle in vain, her body spasming as it continued to try and force the new shape upon her. Her nails were lengthening, blackening, and the fur was now growing on her arms, pure white, save for black tiger striping.
Tiffany quickly realized that if she didn't fight the change, it didn't hurt...even more importantly, it felt GOOD. Her own changes were happening much more quickly, as mentally she gave into them, urging them forward. Her eyes were amber and bright, her body gradually becoming covered in the light orange fur, dappled with black spots all across it. Her breasts swelled a full cup size, straining at the fabric. She tore the bra away, twisting at the buds of her nipples as she moaned, now fully acutely aware of what was happening, and wanting it.
