With her friends gone to their parents with the knowledge that they'd probably get some sort of punishment Nina was on the couch as her father had her laptop open. "So... I have no idea how you got this nor how exactly it works. I do feel however that what occurred last night was inappropriate. As such I feel like a proper grounding of sorts is due. One that I've talked to your mother about."
Nina mumbled "No internet?"
Joseph thought for a second and said "You'll probably not really be using the internet much yes, but if I just said no Internet I couldn't use it either. Even if I did unplug the router no doubt you'd find ways to access the internet anyways. You are just so independent at your age, and it's really hard to properly control a teenager of your age with your agency." Nina felt a chill down her spine as her father grinned and said "However you just got something that can change that so..." Joseph hit the enter button and his pre-recorded changes started to occur. The immediate thing being that the laptop was changing to be more professional as it was becoming his. "Well then the changes will be complete in an hour. Feel free to use your agency however much you want while you have it." Joseph got up and started to walk away and by his calculations 9/60 every 6 or 7 minutes she'd be losing a year till she was a 4 year old. Much easier to take care of. Meanwhile Joseph was going to fully prepare himself for his own changes.
Nina pouted a bit as her changes went through. It was interesting in a way to see how much you've grown. Somewhat slowly as her body took back it's gifts of puberty. Thankfully her clothes shifted with her, and the younger she got the more she didn't like this change. Heck her idea for her change was to be able to enjoy having giant breasts without destroying anything. Here getting younger got rid of most of her freedom and sexuality. Nearing the end of her change the chair in the living room she sat in was a small princess designed one, and she could barely even peer above the sofa table. She just ended up pouting in her chair unsure what would happen.
Joseph however was enjoying his change. His wife would probably also enjoy her change as both decided if their only child would be younger they may as well also get younger... plus that other change.
