First, she has to look the part

"Kim, when I snap my fingers again you're going to wake up. However, you will still be in a trance. In order to play the part of a teenager, you need to look the part. Your eyes will open, and you'll mindlessly go out and shop for some clothes for today. Buy what you think Teens today wear, then come back with it." he ordered "If you understand, say 'yes daddy'"

"Yes daddy" she replied.

John smiled and snapped. Kim's eyes opened, but still looked blank and empty. She quickly turned and walked off, going to get the appropriate attire for her journey into her teenage years.

John gave her a nice smack on the ass as she walked away.
