Melanie shuddered as she suddenly fell involuntarily onto all fours. In shock, she attempted to reason with Beth.
"Arf! Ruff! Arf!" Was all she could managed. Though still fully human, Melanie now found herself forced to act as if she were a dog.
"Hmm, what strange behaviour, Mel" Beth mocked "I assume you must be doing this of your own free will, since any claims I have to possess magic powers are merely the delusional ramblings of a mad woman?"
"Arf! Arf!" Melanie attempted to apologise, to little avail.
"I think having you here may be more fun than I thought. You can stay, but there are a few ground rules. Firstly, you are to be my live in servant - that means you do as I say or face the consequences. Secondly, you must not attempt to leave the premises at any time or you will transform. I shan't tell you into what, I'll leave that as a surprise. Thirdly, you are no longer permitted to wear clothes. I think being permanently naked should remind you of your lower status. My cats see no need for clothing and you are certainly below them."
Before Melanie had time to bark in protest, her clothes had vanished. Beth observed her shapely, large breasted figure for a few moments and a smile seemed to play briefly on her lips before she turned serious again.
"Well, I suppose you aren't totally unsightly" Beth told the buxom, dark haired beauty "But you do need to keep out of sight when I tell you. I often have guests here. In fact I shall be entertaining a very important visitor shortly - a gifted sorcerer who is less kindly disposed than I am to annoying outsiders. Still, seeing as there's no such thing as magic you shouldn't have anything to worry about. Now, scamper along like a good girl, I might let you walk on two legs again later if you do as you're told"
