Jack looked at the scared parents watching their suddenly grown kids not only making love, but their daughter had a penis and their son had a vagina. Jack decided that those two needed to get in on the fun and decided to age their new genitals so it matches their adult bodies. "I wish that Ben and Morgan's new genitals would age to match their adult bodies and both would get as horny as their children."
As Morgan tried to comprehend what was going on, she felt a tingling in her tiny crotch. Her little pecker was growing.
"Ben, my my my...pppenis is growing!"
Ben stopped looking at the kids and at his wife's rapidly growing junk. Morgan's penis was not only growing in length but girth as well. Her little balls also dropped and grew. Soon she had the dick and balls of a teenage as pubic hair grew all over. Looking at his wife's growing genitals was making him moist. 'Wait, moist?!' he thought. Ben looked down at his once tiny little slit as it had now grown and his pubic hair had grown back as well. He touched his clitoris and it sent shock waves through his whole body. He never felt that way when he touched his old penis.
"Morgan! Mine's aging too!"
Morgan looked at her husband's pussy and instantly got horny. Her now adult dick started stirring as new gained her first erection. They both looked at each other and then quickly grabbed each other as a make out session began. Completely forgetting about their twin kids fucking right next to them, Ben and Morgan were quickly undressing each other as they were as horny as teenagers. It didn't take long for Morgan to grab her erect cock and stuck it into her husband's eager cunt.
Jack looked as he now had two couples fucking like rabbits. This was getting him hard as well and soon he cummed in his own pants. Wishing his pants clean, he then thought about what to do next.
