The Fourth Law of Robotics

This is the VR Tenga demo, a sex simulator prototype made for an Oculus Rift game jam held in Japan.
It uses some basic software, the Oculus Rift virtual reality headset and Tenga, a Japanese masturbation toy.
The user is supposed to insert his penis into the Tenga, which is synchronized to the visual stimulation given by the headset, in this case an anime character giving a handjob.
