It'd be slow. A few anonymous images in lingerie. Than maybe have you make some solo videos and send them to random people. Little by little you'd do more degenerate things. Eventually I'd use the app to make you a slut in your personal life. Have you write on yourself things like 'Free Use', 'Cum Dump', or 'Rape Toy' where anyone could see it. Your mind would be warped so you think walking around in nothing but a micro bikini is okay to do. Finally sending everyone in your contacts a message asking to be fucked senseless, and posting your address asking for anyone to come have their way with you online. Your mind would tell you to make videos of it all, and post it on every porn site with your real name and address.
