I remembered watching a JAV that has this storyline:
Japan's birthrate is at a dangerously low level. So the government came up with this policy that men can grab a girl anytime anywhere and do as they please, with the justification of "making more babies". The women have to comply, else they would face harsh punishment. Needless to say, the video shows the male porn stars randomly grabbing the JAV stars in an office etc. and doing them there and then.
I really like the setting of this JAV. But too bad I can't remember what's the code or who acted in it. Anybody have knowledge of this JAV or any other JAV of the same genre?
