By the you are at your house you hair is down at your shoulders and Maddy's is just above the neck.
Once you are inside you give her a tour and show her your room.
"Do you want to watch the changes happen?" you ask.
"Yes" she replied.
Both of you strip, you, realizing you were becoming a girl changed your room to that of the girl you were becoming. Instead of boxers there were panties and you guessed that those were C cup bras. Looking at Maddy you saw her short hair looking closer you saw some stubble. Her face had become less round, and her curvy body had become less round.
You then looked at yourself. You had long brunette hair and a soft round face. The rest of your body had lost all its hair. Your hips had become rounder slightly and your waist had contracted slightly, giving you a good hourglass figure.
You look at Maddy, she looks like a hot boy but with breasts and a vagina. You then have a feeling in your nipples, looking at Maddy's breasts disappear you know whats coming. You look at your nipples and see breast buds, then they push out and grow until they become full, round C cups. You are about to cup them when painfully you cock gets sucked into your body to be replaced with a vagina.
After its over you look at Maddy. She is a sexy 16 year old boy and you are a sexy 16 year old girl in the same room naked.
What happens?
