Over the next week, Sherry will slowly take over Jenny's life. By the time the week is over, Jenny will be living the life of Jeff's mother.
Mental Changes: Sherry will think like a teenage girl and Jenny will think like a mature woman and mother.
Reality Alteration: Sherry will not be aware of the changes. Jenny will be aware, but will be unable to tell anyone or take any action to reverse the changes.
"Are you 100% sure about this?" Jeff said.
"Yes...I mean...Being stuck and not knowing if I will go back to normal is half the fun for me. You could like her better than me," Jenny said.
"I doubt that," he said, kissing her.
She hit enter. "We'll see."
