Meet Milly Madison. She's a 16 year old girl with nice friends and loving parents. But she longed to want more. She wanted to see what it was like as a guy. She always thought that guys had it better and she needed to prove that to herself. So one day, she found a potion that would do just that. She took of her clothes and drank the potion and waited for the transformation to begin. Yet nothing was happening. "What the heck?! I though this potion was supposed to turn you into a guy!" She was completely disappointed to say the least, but suddenly a bout of drowsiness came over her and she fell asleep. Without her knowing it, the transformation began. Milly grew a few, turning from a 5' 2" to 6 feet. Her hair stayed the same though. She would need to cut it when she woke up. Then muscles started to form and her body pushed in the bed. Her breasts were the next to go. They went from B-Cups to flat and became replaced by flabs of muscle. The next change came to her groin area. Her vagina turned into balls and came down in between her legs. They then proceeded to get hairier. Then the clit started to come out. It slithered out of there like a snake and formed a penis that was 1 foot erect. It was already starting to leak, when she started to unconsciously cum. The warms substance from her package spraying all over her naked body. Her feet then changed to size 12 and the transformation was complete. A few hours later, Milly woke up. She felt like her skin was chapped, but this was courtesy of the cum. She walked up and went to the bathroom blissfully unaware and went to use the toilet. She expected to go in it, but her new dick would only let it hit the wall. It was then that she had realized what happened. "Holy shit! I'm a guy now!" Milly screamed with her new male voice complete with cursing. She got up and admired her new body. The breastless chest. The increase in height and most of all her dick. She looked at the meaty thing and slowly went to her room. She decided to get it erect again and stroked it up and down. "Ah... That's the stuff," Milly thought to her self as she exploded out the dick again. Acting like she didn't care, she drank it as it came out. It wasn't as disgusting as she thought it was. She then decided to stay with this new life and would name herself... Willy.
