I want to be 13 again. So I am still a teenager but still quite young said your girlfriend.
You knew you couldn't talk your girlfriend out of doing it. So you watched as your girlfriend think of becoming 13 and instantly she began to grow younger. Her breast shrank as so did her height. Her clothes became less mature. Then after a few minutes your girlfriend had become a 13 yr old. She had some freckles on her face and her hair was shorter. Her breast look like they were just starting to develop.
Oh my god it worked squealed your girlfriend which you and her both laughed of how high her voice sounded.
The single bed you had asked for in the room had changed into twin beds since a 25 yr old cant sleep with a 13 yr old. Your girlfriend quickly checked her suitcase and found that her clothes had been replaced with ones that a girl her age would wear. There were training bras, less sexy outfits and a 1 piece bathing suit instead of a bikini.
Thats when..
