It was Friday evening and I knew Jeff would be on his way home from work. The drive from his work to the house was a short one and I figured I could use the spell to change him into a girl and he would make it home before he even realized the change. This was going to be the greatest practical joke ever. The manly Jeff, a girl for 24 hours. I very carefully read the spell aloud three times. As I did I started to feel very strange. It felt like my insides were twisting and turning inside out. I blacked out and when I came to I felt a huge heaviness on my chest and no penis where my penis should be. Clearly the spell was wrong, it had changed ME into a girl!
At that moment Jeff entered the house and saw a hot girl in the living room. He didn’t care who this hot girl was, he was already starting to seduce me. I was thinking different as a girl, so turned on by him and I wanted his cock bad. It wasn’t long before we were naked and he was thrusting his throbbing cock into my new pussy. It was such an amazing feeling. Maybe it’s best that I don’t tell Jeff that he fucked his best friend.
