The world of videogames isn't averse to adult-orientated games – as our run-down of the best games to 'enjoy' over valentine's day no doubt proved, aroused 8-bit caricatures and all – nor indeed is it of frankly absurd add-on peripherals, such as Nintendo's Vitality Sensor (still yet to see a release) and bowling ball attachment for the Wii. Really. But even so, we struggle to come up with the words to describe what Japanese adult game studio TechArts 3D have come up with.

Simply put, it's a USB controller peripheral, named 'OnaCon', that allows players to put their member into, whereby it is said to be able to keep track of players' total time of masturbation, their 'play' frequency and their “average speed”.
