For a moment, Kelly thought about Katie. She was still her mother. She had responsibilities, even if the girl was in college. Those thoughts suddenly subsided however, as a new and much more mischievous thought came into focus. "What would it hurt to just ... let go a bit, have some fun?" As she thought this spaded appendage lightly flicked in the air as she looked about, eyes focusing on a nearby vending machine.
She was thirsty. She wasn't before but she was now. And she wanted a drink, badly. Racing up to the machine she put in another quarter, almost desperate for something to quench her sudden and all consuming thirst. "Please provide desired species." the machine droned, a light female voice, mechanical and curious.
"Imp" said too quickly as Kelly began tapping her foot, a little fidgety as a clear bottle of pink soda dropped down into the receiving slot. Without a second thought, Amy opened the top and began chugging.

She had shrunk, a lot, finding herself barely over 4'9 now with only the faintest swell of a chest and, as she looked at her torso, a lack of a belly button.
But her tail was the same. Bigger now. Or at least it looked it. It didn't shrink, at least not as much as the rest of her body. As she watched though, she could see the light blue color beginning to spread, a wave of surprisingly delightful pinpricks happening all over her skin, going from a nice normal human color to a light blue, the same color as her tail.
The feelings, the absurdity of it, caused her to giggle. A musical sound, innocent on the surface with a deep undercurrent of mischief and malice. "This is awesome!" grinning bright and broad. Eyes scanning, the changing imp fixed her gaze on a....
