Have you heard about Custom Maid 3D? It's a game where you create your own custom maids and then do things to them. Sexual things. And you do these sexual things by using the Ju-C Air Support controller. It resembles a PlayStation Move controller, with the slight difference being that you actually stick your dick into the device.
Once you've strapped yourself in, you can, uh, well, masturbate with it. The peripheral will respond to your stroking, speed, and even depth. It also features an analog stick and buttons so you don't have to take your hands off the thing.
Okay so this is a bit of old news as the game and device came out in February in Japan. So why are we bringing this up today? Because it just got Oculus Rift support. The developers have released a beta patch to enable the harmonious union of virtual reality with virtual masturbation. This also makes it the first sex game with Rift support, beating out Wicked Paradise. Uh congrats, I guess.
