"...you change that family's ethnicities, ages and genders?" she said, pointing in the direction of a couple and their children. That was Kevin Howard, his wife Lily and their children, 15-year-old Lou and 10-year-old Cole.
"I think they'd probably notice," Ty laughed.
"Then maybe change reality so we're the only ones who know anything's different?" suggested Rebecca. "Can you do that?"
"Yeah, I'm pretty sure I can," Ty replied.
"Don't tell me what you're wishing, though," Rebecca added. "I wanna be surprised."
Ty nodded, and figured he'd have his powers decide for him. Before their eyes, but unnoticed by everyone else, the Howards started to change. Lily's breasts receded into her chest, her blouse turned to a muscle shirt, her pussy sealed up and two balls formed inside it, and her clit swelled into a seven-inch shaft. He was now Liam Howard.
Meanwhile, Kevin's chest rapidly perked up into D-cup breasts, his figure turned slim and curvaceous, his shirt and jeans were replaced by a pretty sundress, and his penis receded to a tiny nub, while his balls sucked inside her new pussy. Her skin darkened to a dark black tone as her heritage was rewritten. She was now Kelly Howard (nee Nazani), Liam's wife.
Young Cole was the only one spared changing his gender; he aged through puberty, his balls dropping and his muscle mass and body hair growing rapidly until he reached 16. His ethnicity was changed to be Hispanic, and he became the Howards' adopted son, Cortez.
When Ty started to change Lou, his concentration slipped, so the boy was, unlike the rest of his family, entirely aware of the changes affecting him. He felt his balls move up inside him and his penis start to shrink, while his shorts shifted to a skirt and his T-shirt to a strappy top. He felt himself sprout soft B-cup boobs that filled out his new top, and saw his skin change from a pasty white to a brownish hue midway between his mother's and father's. He felt his cock recede into a clitoris and his pussy open... and SHE felt HER mind being filled in with her new life as Louise, the Howards' daughter. It was weird- she could remember her old life, but also her new life. She looked up at her family as the changes finished, and saw them continuing as if nothing was different.
"Wow, looks like it worked," Rebecca observed, surprised at how big the changes to the family were and that no one had noticed.
"Yeah, it went a bit weird for a second, but I think it worked out," Ty laughed.
"Nice," said Rebecca. "Wanna try another change?"
Ty nodded, not seeing Louise look over confusedly at him...
