You drank the vial with a dragon on it and began to grow purple scales on your back with red on your under side. Following that your spine cracked putting you on all fours making it impossible to stand on two feet again. Next the scales worked their way up your arms tranforminh your hands into 4 digit claws with one in the back for a thumb.then the scales transformed your head. Your skull reshaped and horns s grew out of the sides of your head. Next you felt pressure in your back and you screamed as the wings grew in crackling bones all the way next you notice pressure in your hind end and a tail exploded out and you roared in pain. Your feet then reformed to having 3 digits and gained the trait of claws.
Just as you thought it was over you feel stabbing feelings in a straight line down your spine to the tip of your tail, and then spikes bursted out cousing blood to go everywhere.
A mirror then appeared and you took a look at yourself and you looked good besides the blood. But then you saw that you looked slender for what you imagined as a dragon, and then you felt a tugging sensation on your dick so you rolled onto your side to investigate by the time you did you notived that you didn't have a dick anymore you were female.
"Oh fuu...." you said relizing your feminine voice.
You then noticed 3 doors and you need to choose one.
