Exactly how it happened you have no idea. Of course. It's an impossibility, right? At first you thought it had to be some especially peculiar dream, and it was only as you climbed out of bed and prowled around your bedroom that you realized, no, this was very real, regardless of how strange it seemed. But when you wandered into your bathroom, sleepiness giving way to unease, you saw for yourself in the mirror.

A tail. A tail growing from your backside, just above the cleft of your ass.

It had actually pushed your panties down to the point they were drooping along your thighs, to be irritably kicked off as you took stock of your new appendage. This wasn't some pink stub of flesh, some vestigial tumor -- this was a full-fledged tail. Long, sleek, adorned with lustrous golden fur, and swaying over your ass in a way you might consider seductive, if you didn't know better.

How did it happen? Who knows? Does it matter? Maybe a voodoo curse because you crossed the wrong oddly witchy shopkeeper. Maybe a coworker called you a cougar at the Christmas party and after you got over the annoyance of it part of you decided to embrace it. Maybe it's just something that's been waiting to reveal itself all your life, a bit of wildness bursting out to break up the tedium of everyday life.

But as you sway it from side-to-side, feeling the amazing clench of muscles deep inside your body (my goodness, you have impressive control over it already), you find yourself wondering a couple of things...

Is a tail all there'll be to this?

And more importantly ... what will sex feel like with this thing?
