According to Maniac, the Japanese developer Tech Arts is working on a title called 3D Custom Girl, which will be released at the end of October. The women present in the game cover pretty much every single Anime cliché in the book. The eroge will come with a USB-peripheral, shaped like a vulva, called the “USB-Onacon” that allows you to control your more intimate interactions with the virtual characters of the game.
Are you done re-reading that last sentence over and over again? Good! As you may have guessed by now, that controller has the form of a vulva. The game together with the peripheral costs around 90€. You can check out the slightly not safe for work website and give the game's demo a try -- minus the motion controls of course.
