Mary shrank down just a little bit more and finished her transformation into a small yellow canary. This wasn't going well. She was a canary! And her best friend wanted revenge! Mary hopped around in panic. She didn't notice or see Jess pick a vial up and drink half of it down.
The vial began to work on Jess. She took off all of her clothes, she didn't want to ruin them. She folded them neatly onto Mary's bed. Already the changes were becoming noticeable on Jess. A small nub had appeared at the base of her spine and lengthened into a long tail.
Mary had hopped around so that she was now looking at Jess. She hopped backward in shock. She was naked! Mary felt a sinking feeling, again. Jess would only take her clothes off if she was wanted to become something else. Sure enough, Mary saw that Jess was indeed changing. There was something about the look of Jess, she was changing into something that canary Mary didn't like.
Jess let out a sensuous deep-throated growl as she ran a hand over one of her large hips which was now showing signs of new fur. With her other hand, Jess picked up wire cage and turned toward Mary. Jess grinned, but her grin was odd. As Mary watched, she saw Jess' face push out into a muzzle, her nose darkening. Fur sprouted in quickly, a dark dirty brown, but looking very soft.
Jess' ears next moved to the tops of her head, becoming pointed. Jess started walking toward Mary with the cage open and her body still changing.
