Geoff grinned evilly as Squeaky laid on his bed changing, mentally patting himself on his shoulder for his acting skills. Oh, he had been honest about the reset option and also for the change him back later part. But he would have been able to change Squeaky back to his old self, as the chronivac created a back-up file for anyone who is changed with it. Therefore they would only have needed to use that for turning Squeaky back.
There had been a reason why he had wanted Squeaky to hit the submit button himself. While the chronivac could affect reality and change peoples memories and minds, that only worked for the people directly affected by the users changes. It was a safety reason, so you couldn´t change someone without them accepting the changes, at least in theory. So it had been a lie that nobody remembered Aidan´s human life. If Geoff had hit submit himself that fact wouldn´t have changed, as it wasn´t changes to his mind or about him.
Also Squeaky hadn´t noticed a collapsed part in the program labeled mental changes. Geoff had edited them before Squeaky had looked over his shoulder, so he didn´t know. And this changes wouldn´t have worked if Geoff hit submit, either.
Thanks to Squeaky´s trust he had effectively killed his old life himself. Nobody beside Geoff, as he had excluded himself, remembered Squeaky´s old life now. So Geoff and Squeaky were the only ones knowing Squeaky used to be human. And when Squeaky was finished changing he himself wouldn´t know anymore, too, leaving Geoff alone.
Next to the "forgotten by everyone" part hidden in the mental changes were changes for Squeaky´s mind. Squeaky wouldn´t remember ever being human, but be Geoff´s living demon style sex toy. While he would gain control of himself, to him it would be normal, and he had no reason to leave Geoff´s side. Squeaky would be eager to please him and others Geoff had allowed to use him, and never complain or getting angry.
Squeaky moaned in pleasure while he changed. He was shrinking, slowly vanishing into the rubber underwear he had been wearing. At the moment he was making plans for what to do after he was free to go, plans that were slowly vanishing afterwards again unnoticed.
Half a minute later Squeaky´s changes finished, the last of his body was absorbed into his new default form, the rubber underwear. In the same second the mind changes took effect on him, erasing Aidan Starns completely out of him. He was Squeaky, Geoff´s loyal rubber sex toy. He used to be just a mindless pair of rubber underwear and Geoff had gifted him a mind on his own, as well as a more animatic form than his original one. He would be grateful forever and do anything Geoff could ask him to do.
Geoff grinned as the chronivac showed that the changes were finished. Most entries cleared themselves out or changed, as Squeaky did no longer need a gender, an orientation or an age. Instead the settings changed to fit his new default form as rubber underwear, adding his demon form under additional forms with many settings Geoff could edit later. Another message popped up, resigning and reserving all rights to change Squeaky, both physical and mental, to Geoff alone. Now Geoff could change Squeaky´s mind however he pleased without his help.
Geoff got up and took Squeaky off his bed to put him on. Squeaky instandly started to suck on Geoff´s cock, another point he had added before to Squeaky´s mental changes list, to be always sucking the cock of his wearer. He would also absorb the cum, as well as any piss or shit his wearer pressed into him.
If not in his default form he would only absorb what he was told to, like Geoff had spoken about with Squeaky before, not that he remembered their deal anymore, as it vanished with his old life. Geoff would need to test the other edits as well later on the party. He had lied about that as well, as it was just a normal party with some other students Geoff was invited to.
Now he had two options for the back-up file for Aidan, either he could save it and maybe use it later to change anything into a new Aidan without any memories from after his first changes, or he could simply delete the file, erasing him truly completely. But that decision could be made later, as he had a party to go to.
