Zack thought about what he should do. He then said, "Every midnight, I will swap my body between one of two options: my body, and the body of a hot teenage girl version of me. No one but me will notice any difference. All of my possessions will swap to match the me of the next day."
Zack the said, "It is almost midnight, and I am the only one awake." Suddenly, the outside world got pitch black. There was no moon tonight, so Zack turned on the lights in the tree house. The clock on the wall read 11:59. Zack smiled.
A minute later, Zack's body started tingling. Then he started feeling squeezing, pulling, and stretching sensations. They didn't hurt, but they felt weird. Then Zack looked in a mirror. His body was getting slightly taller, his feet much smaller then the size 11s that they were before. Zack estimated his feet to be at size 5. The his legs got longer, his thighs inflated, and his penis sucked into his body. Zack's waist got mush narrower and his chest inflated to hold size DD breasts. Then Zack's face changed, becoming more feminine, and his hair lengthened to the middle of his back. It then lightened to be a goldish-yellow color.
Zack, now Zoe, walked into one of the bedrooms and fell asleep.
When she woke up, Zoe climbed down from the tree house and went into her bedroom. It was completely changed, his walls painted differently, his bed different, and his room was no longer messy. Then Zoe her her mom yelling, "Zoe, get up! Time to go to school!"
Zoe said, "It's now Saturday!"
Zoe's mom's voice was replaced with silence, and Zoe smiled. She said, "my parents are now my younger siblings, and my mom is an older version of me. She is the best mom in the world and makes the highest salary at work in the world."
Zoe then got dressed. Her clothes had changed to match Zoe's body. Then she walked downstairs and whispered, "My boyfriend is Nate, my best friend, who happens to be the star on the school football team. He is coming over soon."
