He saw a couple nearby with a pair of strollers. They were a young couple in the mid-20s and each stroller had a baby, supposedly twins. One was a boy and other a girl. Jack got hard when he thought about what to do. He wished himself invisible and that he could not be seen or heard unless he indicated it. He approached the couple and kept following them. As they reached their home, he made his wish.
"I wish the man and woman would have their genitals swapped with their babies."
He felt the ring warm up. The world seemed to shift and the folks felt a little dizzy. Both babies started crying and the young couple took them into the house. Jack followed. He watched as the couple took both babies to the nursery and placed them on the changing table. Ben (the father) had his daughter Melina and Morgan (the mother) and her son Nick. Both were taking the babies' diapers off when they both were shocked by what they saw. Melina had now a huge cock between her legs and Nick had an adult vagina. 'Whoops' Jack thought, 'this should make things more interesting.'
"Oh my God. Ben, that's your cock!"
Ben looked closer at his infant daughter and if he saw a row of dicks he could easily pick out his and there it was sitting in his daughter's crotch. He immeditately pulled down his pants and was shocked to see a little slit in between his legs. Morgan took her jeans off as well and was surprised to find a little baby pecker where her lovely vagina once was. She had balls the size of grapes as well.
They both looked at each other shocked as the babies kept crying.
