David looked over his son's shoulder and stared at the screen with a bit of confusion. Jeff's statistics now read:

David took a step back, his mouth agape in surprise. He hesitated a moment, but stepped back to watch as the changes took hold of Jeff. The most shocking and dramatic was the tufts of hair that wove into place around his son's expanding chest and forearms, which seemed to ripple as muscle bulked out beneath his taut flesh. Almost as an afterthought, Jeff pulled his pants right off again - just in time as his own thighs bulked up with corded muscle and began to stretch him taller than before. His son's face changed shape slightly as the softness of youth was replaced with a hard jawline that was quickly covered by a forest of silken beard. David tried hard not to look, but at a certain point couldn't help himself from looking down as Jeff's already impressive cock grew downward and gained even more mass. The femboy was suddenly conflicted about what just happened.
"Uh, Jeff, what did you-" Jeff reached down to his much smaller father and pulled him up for a hard kiss, but David pushed away. "Hey, hey, what are you doing?" the femboy sputtered in his high-pitched voice.
Jeff looked confused and when he spoke, his voice had a new deep tinge to it. "You liked feeling small and you love the body you're in now. And I have to say that I do, too. I thought that we could make this more fun if I was really much bigger than you."
"And older," David added, suddenly feeling the difference in their age as he ran his eyes across his son's hairy body.
Jeff let his hand fall onto his new thick cock and let his fingers tease along it. "What do you say, David?"
