Not much out there that’s chose your own or interactive. Closest thing you’d get to that type of content since choose your own adventure porn in and of itself is fairly rare would be H-game content. One of the things I wish the HANDY manufacturers would have done is develop some kind of API for use w/ the unit that developers for H-games and similar content could easily hook into.
There are tons of projects as simple as something like Fapqueen up to full scale 3d projects w/ scenes / renders like Project Helius or Subverse that could easily implement something like this (Especially Helius since its ALSO VR focused)
The virtual blowjob project shows this kind of thing should be possible to do, but I don’t think anyone’s trying to push the bar forward.
