You look around at the other mirrors. Perhaps one of them can change you back. The next on is a black mirror, but when you look at it, you can't see anything other than darkness.
Even when you are close enough to touch it you can see nothing. Pehaps this is the mirror who change you back. You want to risk it and touch it.
Again the black liquid engulfs you. When you look up again you see nothing other than the black mirror. Perhaps this one nothing happened.
But then mirror gets a bit brighter you see your body! Your face is now even more feminine and your short shag hair is a bit longer. Also you have two black signs in your face, like black intendet strips which come from your ears and ends on your cheeks.
But your greatest shock are the two small and curved horns on your forehead which break through your hair.
When you look closer you also notice that your breasts are even one cup-size greater and that you now wear only a snug and sleevles leather top which shows a lot, but hides nothing. So you can see your exposed belly and you mention that there is another black sign which looks like a intendet whirl around your navel.
You see that this time your lower body has also changed.because your legs are now hairless and it looks like you has lost a few inches in height. Also you wear now black high heels and a black leather skirt. These all fit perfect to your red skin, but another scary change which takes your complete attention is a hairless tail with a bunch of black hair at the end, which spreads out of your lower back under your skirt.
You can't see where it is connected to your body, but you doesn't want to lift you skirt because then you can see some subtile changes in your crotch and the missing of a bra says you that you probably doesn't wear panties.
When you look back at your mirror self you see that black wings spread out of your back. You turn around and see in the mirror that your top was only hold by a knoted band and, so it doesn't covers a lot of your back. Under your shoulders you see the places where the black wings changes into red skin. They are big enough to cover your whole back when you fold it on your body and they look a bit like bat wings.
You look at yourself for the next five minutes, but it seems like you can't deny it: You are a succubus now!
