Didn't they have that eyeball licking fetish some time ago? Japanese seems to be into licking all kind of things... They seems to have evolved one step from enjoying all kind of liquids and dick growing jelly monsters to taking a taste of more solid forms of things. Now it's going to be only a matter of time until they figure out what to do that thing between their legs. This might be the downside of spending too much time with high technology and robots and slowly try to move back to reality.
