You were calmly reading an ancient book of demons, a book that turned out to be real and powerful, on one page you cut your finger releasing a little blood. You didn't give it much importance, you put the book away, put on your pajamas and went to sleep like any other night. When you wake up, your vision is cloudy and you can barely make out that you are in a room, a room that is not yours and is too elegant. You took off the sheet and...your body was different, your chest as well as your thighs and rear had grown quite a bit, you had new curves on your body and you could almost feel that you had a tail. "Dear? Are you okay?" You hear a male voice speaking gently, a voice you don't recognize. Scared, you looked everywhere and saw a shadow in the background.
