Jess popped the cork off the Human vial and held it up to Mary's lips. "How much do you want?"
Mary thought for a second. She just wanted her hands back for now. "I guess just a little." She opened her mouth to take in the vial, and Jess tipped it over. Mary attempted to cup her lips around the vial to make it easier to swallow, but Jess was so busy watching Mary's paws for a sign of change she failed to realize what had happened. To her, it felt like the vial was falling out of her hand, and she moved the hand to grab on tighter. Doing so, however, caused it to tip even farther into Mary's mouth, making her choke. As she moved her head around, the vial completely emptied into her mouth. Jess pulled it out as Mary gurgled, clutching her throat with growing hands. After a couple more chokes, she said it was all right. "I think I just--gah--need some water."
"I'm sorry," Jess said as blond hair bloomed out of Mary's head.
"It's fine, it's not like that was poison or anything." Mary filled a cup with tap water and swallowed carefully. She began to get taller, no longer at eye level with Jess. "Besides, this is what I'm supposed to look like anyway, right? Now that I think about it, I've had enough of being a cat for a while." As her hair proceeded to her shoulders, her fur disappeared. She watched her two lower pairs of breasts shrink back into her and her tail get shorter and shorter.
Within a minute, Mary had changed back into a human. Apparently, however, the Female vial changes she had before changing into a cat were reversed as well. Her body lacked a perfect hourglass figure, though she still looked quite attractive, and her hair stopped at her shoulder blades.
"Now that I think about it," the six-foot woman said to the four-point-five cat, "Maybe this is my chance for revenge."
Jess saw a sparkle in Mary's eyes that indicated she was joking, and thus let out a giggle. She saluted Mary. "Aye aye, my master! Your pet obediently obeys!"
Mary laughed. "Okay, then!" She said. "Got a collar around here?"
Jess went to her bedroom closet, pulling out a black collar she used to wear during a short-lived goth phase. The belt buckle on it was shiny silver, and Jess found she had an unusual attraction to its sheen.
Mary looped the collar around her neck and barked orders. "Let's clean up this mess." The two straightened fallen chairs and disposed of the torn girls' clothing. Jess even vacuumed the rug for shed cat hair. Even as she worked, she enjoyed the feeling of a cat body. Her fur felt so soft, and she absolutely loved the sensation of having a tail.
Once they were finished, Mary called Jess over. "I'm about ready for another change. What about you, my pet?"
