Thinking things over, Ty decided he was going to have a little fun with this and take it one step further. He was going to give them each other's bodies but the same faces.
The boy was checking out his enormous man sized dick in wonder at the same time his father was looking at his little boy pee-pee in abject horror, wondering if he was in a dream. If someone could see the two of them at once in a cross section they would have seen the boy outgrowing his clothes until he was well to the height of his father, at 6 feet 5 inches and his father shrink to the size of a small child. But their heads remained the same.
Gingerly the father stepped away from the toilet and tripped over his own man sized pant legs. Meanwhile, his son didn't fit inside any of his clothes anymore and had to strip down to his underwear. He scratched at his hairy chest. Hairy chest!
"Daddy! Daddy?" the boy cried out. He barely knew what to make of being tall all of a sudden. He and his father exited the stalls and looked at each other in horror. Well the father was horrified. He was now a practical midget. Only midgets at least have testosterone and dicks that could produce sperm. His little pee pee now couldn't even do that while his son was sporting a fit, athletic godlike body but with a cherubic angelic face of innocence. His son looked way down at his father.
"You shrunk! You look like a little boy! And...I have muscles! And armpit hair! Look daddy!"
"This isn't possible..."
"Oh, but it is!" Ty stepped forward. "And I also changed reality for everyone so that no one thinks it's anything unusual. Your son is now the real man of the house and you are just going to have to live with it. Now exchange clothes before someone sees you and your son's adult body with your dicks hanging out.
The boy, whose name was Tommy, took his dad's underwear and before putting it on, felt up his enormous shaft.
"I can't believe this! How did you do this! I have an adult body and..and..."
"I must be hallucinating. It's the only explanation! This sort of thing isn't possible!" said the father, whose name was Brant.
"Well see, for now it is. You will go about your daily lives only Tommy you will be the tallest kid at school and Brant, you will be seen as a freak midget. Tommy you technically have a man's body right now so you can get women pregnant if you should have sex with them. Make sure you use a condom when you fuck. And feel free to spank your dad if he gets out of line. Your son will call the shots at home, even if you are still going to work and if you don't like it, I'll exchange your heads and give him your life entirely. Got it?"
Ty and Dustin laughed at the two. Tommy now wore his dad's suit and smiled, loving the feel of his muscles and the fine fabrics. They made him feel so manly and his father was dressed like a little boy and felt totally humiliated.
"Do you really think we should leave them this way?" Dustin asked. "Maybe we should have everyone see Tommy as the adult and Brant as the kid."
"Hmmmm," Dustin thought about it and then decided...
