Your ears already have a coat of white fur covering them and are starting to get longer. As they grow the they get softer as the cartilage thins out. You try desperately to tug at the collar again, worrying that it is the key to whatever is happening to you, but it yields no more now then it did before. It's then that you begin to feel something bulging between you and the chair you're seated upon. With dread you stand and look at your rear to confirm that a rather large tail is sprouting from your tailbone. You run your hands through the white fur. The sensation it gives you confirms that it very much is your tail.
"No no no no please I don't want this." you say, pleading with whoever or whatever may be doing this.
"Perhaps you shouldn't have entered my home. Slept in my bed. Used my shower." the nondescript voice whispers.
"I'm sorry." you say weakly, tugging at your now fully grown bunny ears.
"I'm not. Now I have my own pet bunny girl. If you behave yourself perhaps I'll set you free. But then again if you truly behave yourself then perhaps you won't want to be set free. Now then you may as well go back to sleep. I'll play with you in the morning. You try the door you came in through, now no longer caring that you're still nude. You just want to go home, changes or no. The door refuses to open, however. After sitting down at the edge of the bed, fretting for a time you decide you've no other option but to go to sleep, or at least crawl beneath the covers. You find it difficult to sleep as your body continues to change.
