I've always wondered how much of the action in JAV is a genuine expression of the moment and how much is it the director's instructions. For instance, when you hear an actress ask for more during a sex scene- is this her true reaction to the sex act, or has she been instructed by the director that at some point, she quits struggling and actually craves more? I guess the basic question is, are the actors given a basic plot outline(if any), or is each scene carefully plotted for them as to how that scene should be played? Any ideas would be appreciated. Thanks.
