Jeff smirked to himself, hearing this. He had to admit, the 17 year old girl would be the spitting image of a daughter if he had one. Still in his core, he was a teenaged boy and he had teenaged desires.
"Okay, 'daughter.' Since I am the father, let me have the chronovac please." he said.
"Aww, do I have to?" She whined.
Jeff nodded holding out his hand, "I'm in charge now...remember?" he winked.
His mom giggled, and stayed in character, pouting as she handed over the device. Jeff nodded and took it. "Alright now ...." as he held it he made subtle adjustments to them both. He first changed his mom's memories and her status....making her think she was naturally this age. But he erased all memories of her being his mother and replaced them with her being his girlfriend. Then he set his own age to 17. As he pressed the confirm button Jeff felt his body diminish, return back to the lanky teenager.
The girl opposite him blinked and then, smiling wrapped her arms around his waist. "Oh Jeff, you were so handsome being grown up...but...im glad your back to our own age. Maybe with this we could...you know...enjoy some alone time together?"
