A personal friend of mine, Anatares, is having some financial trouble at the moment, so I thought I would give her a bit of a signal boost to help her out. Not that I have much range as far as that goes but still, I can try. She mostly does writing; with her biggest work being an undertale fanfic.
She doesn't do much, if any, mind control themed writing that I know of, but I have heard more than a few people who like Adventure High mention that they also enjoy Undertale so if you like fanfiction and Undertale who knows, you just might like what she's got so far.
You can find what she's written here: http://archiveofourown.org/users/LadyAnatares/pseuds/LadyAnatares
