Sometime around 2008-2010, I read a rather long erotic mind control story, I believe on Literotica.
A young University student was doing a class project with a rich female classmate. During the course of testing her for ESP, he discovered her could access her brain, like a connected external hard drive. He experimented from there, eventually discovering he could make her body change as well as her mind. She becomes his devoted girlfriend, buys him a car and furniture for his apartment. Her mother eventually gets involved, and he has to control her. He discovers that the mother had been secretly seeing the dean of his University, and begins to control her as well. It had several parts, culminating in the college Dean going rogue and the main character having to copy his brain into her body to stop her plans.
It wasn’t any of the Master PC stories. I don’t think so, anyway. It certainly never used the phrase ‘Master PC’, but he was using a computer to edit people.
A few other details I can remember:
-he had a favorite pornstar, and watched a lot of her videos. Near the beginning, the rich classmate has fallen asleep with the brain scan helmet on. He played one of these videos, and noticed the sleeping classmate was mimicking the pornstar
-he eventually made a smaller version of the mind control helmet using some kind of mobile device, like an iPhone, I think.
-he edited himself as well, mostly to make him smarter and more attractive, but only went under for short bursts at a time.
I once looked for it(again, years ago) and it had been taken down from the site I originally found it on, but after some googling, I found a copy for sale online. Now, of course, I can’t find it at all. Can’t remember the name or the author.
Good story though, if you’re into that sort of thing.
