You drank a vial with a Vulpine with multiple tails an after you do snow white fur spread across your torso. As the fur reaches your hands they alter becoming dainy, your fingers fused together giving you four fingers, your nails sharpened and reformed to provide traction for slick surfaces, and finally you grew pads on the palms of and on the bottom of your fingers. You stared at your hands in awe at your new hands, but then you saw the same thing happened to your feet. You walked around some to get used to the feeling, but then your legs snapped and changed form to match that of a vulpine causeing you to trip. Surprisingly you stood up just fine, and then your skull reshaped to form a muzzel, and your ears became pointed and moved up your head, and became movable. As the fur moved down your hips you felt pressure in multiple areas in your hind area, and then eight furry tails grew all at once above your rear. Then you looked down to find your dick was replaced by a clitoris and your form was feminine, wide hips, slender form, and a notable rear. As the fur finished spreading to your new feet you felt pressure build up in your chest and you grew a pair of D cup breasts.
You cupped your breasts in curiosity, and turned around to see a mirror. As you cupped them pleasure filled your body, but in the end you were ashamed and stopped. You then felt like you could do more so you followed your instincts and focused energy on your hand, and as you did a small fireball appeared. You were shocked but at the same time you expected it, and as you focused you discovered you could manipulate matter, or use magic with your mind and body. You then turn around and see three doors a temple, a forest, and a book.
