"I sure do!" Jess exclaimed. She uncorked the vial in her hands, noticing it had mysteriously refilled itself. She guzzled what she assumed was the amount that Mary had drunk, then put the vial back in the box with the others.
She felt the tingly-warm sensation, and shivered with excitement and fear. "Did...did you feel funny when you started changing?"
"Yeah," Mary replied. "You'll get used to it. Just enjoy."
Enjoy she did. The growing fur across her body felt exhilarating. She saw that it was coming in gray instead of Mary's orange. She felt other changes as well, such as the growth of her claws and her feet. That's when she realized she'd never removed her shoes. She scrambled to untie the laces, but soon realized she didn't need to, as her foot slipped out of it without much difficulty at all. I must be shrinking already, she guessed.
On her head, her ears enlarged. Growing to points, they traveled up to the top of her head. She found that she could move them with a bit of concentration. Her face elongated very slightly, making a small muzzle like Mary's. It too became covered with short gray fur. Her hair, which didn't lose its deep black color, shortened from her mid-back to only three inches long. It was even shorter than catgirl Mary's blond hair.
Jess felt a bulging in her lower back, and guessing that a tail was growing in, removed her skirt. She watched as a gray and black-striped tail grew out several feet, dancing in the air behind her.
Four extra breasts grew on her chest just below her other ones, and Jess noticed she didn't have a white furred chest like Mary. It was as gray as the rest of her, however she began to notice black stripes were appearing along her arms, legs, and back.
Short whiskers grew from her cheeks, her eyes turned yellow-green and her pupils became thin vertical cat's eyes. Her rough tongue ran itself across her new sharp teeth. She had been shrinking during this time as well, and was now at eye-level with Mary.
"Welcome to the club," Mary smiled. "How does it feel?"
Jess rubbed her hands down the curves of her body. "Purrrr-fect!" she joked. The two women giggled.
"So," Jess said, flicking her tail expectantly. "Now what do we do?"
