Sarah clutched her stomach as a sudden pain ran through her body. She felt like a heavyweight boxer had just punched her in the stomach. Dropping the basket, she fell to her knees, and stared in horror at her reflection in the well water. She saw hair- no, fur- sprout all over her face, and down her neck. Her nose's tip grew dark, and seemed to fuse with the top of her mouth, and both began to expand outward, the sounds of bones breaking and realigning filling the air. She spat out her now-loose human teeth and felt large and sharp canine teeth grow in their place. In seconds, her new muzzle was formed.
She looked down at her body as the pain continued. Her arms were now covered with thick gray fur. The fingernails on both of Sarah's hands grew long and pointed. Very deadly-looking. She saw dark pads growing on her palms.
Her chest was also growing, and threatened to bust the shirt wide open. She figured she was now at least a size 36DD.
Then a ripping sound brought her attention to her legs and feet. Sarah's feet, now more paw-like, had completely destroyed her footwear. The legs were just as hairy as the rest of her body.
Finally, a tremendous pressure began pushing at the base of her spine. Despite the awful pain, she realized it was a tail!
Then, as quickly as it had began, the pain stopped. Sarah slowly got to her feet, using the well for support, and looked again at her reflection. A large gray yellow-eyed female anthro wolf stared back. She hadn't even realized that she had also grown a good three feet taller. "Grandma's going to have a heart attack when she sees me," the she-wolf muttered.
Sarah picked up the basket, putting the fallen goods back in, and started walking wobbily towards her grandmother's cottage.
