"Two to four weeks delivery, my ass"
Mary took out the vials, and looked at each one, one by one. Nothing had broken during their transit, and all that she had ordered was there. Most of the vials held some kind of animal serum, but there were some for body modification thrown in as well.
Seeing that all was well, she took the "return" vial out of the box, and placed it on the kitchen table. ((the "return" vial makes whomever drinks it return to their original form))
Reaching into a cabinet, she took out a small dog dish. It was bright red, and it still had the price sticker on it. She placed it on the table, and poured the "Return" vial's contents into it. As the thick fluid spilled onto the bowl, it hissed and foamed like a can of soda. It had a rather pleasing aroma, also. She placed the vial back into the container, and it re-filled in a matter of seconds.
After placing the bowl on the floor, she went to the front door and locked it. She walked to the bathroom, and took off her dress, and wrapped a large towel around her chest and waist. As she closed the blinds she muttered,
"Great day for a little fun".
Before she really got going, she decided to have a "test run". She picked up a random vial and took a swig. It didn't smell anything like the "return" vial, it smelled more like stale wine, and tasted like it, also.
She raised the vial to her eye level to see that she has just drank half of the bear vial. She quickly placed the vial back, as she didn't know how long the transformation would be.
Almost as soon as she put the vial back, her hands quivered. She watched in fascination as the fingers shrunk, and the skin on her palm hardened.
"This is a lot better than my old kit!" Mary said enthusiastically. she wouldn't be speaking for much longer, however, as she felt her face tingle. She couldn't see for a brief second as her eyes morphed into amber eyes of an animal. the top half of her face began to recede, leaving her mouth and nose in the shape of a crude muzzle. Her nostrils began to flare outward and began to harden into a black wet nose. He mouth changed, also, as her teeth sharpened and lengthened.
Next came her hips. They began to widen and shift so that her legs came out at ninety degree angles, so she could walk on all fours.
As soon as they started, the changes finished. Mary was now a hairless woman with bear forepaws, muzzle, and hips. She walked over to the dog dish and lapped up the "return" serum, and she began to revert. By the time she was done, she had no bear features left, only she stood, naked. She picked up her towel, and thought about what to do next...
