It never ceases to amaze me that these women never fight back when they are being molested and/or raped on a train. I can see if they were drugged, bound or unconscious, but these chicks had ample time and means to defend themselves. It's like they just collectively say "oh well, its going to happen anyway, might as well let it happen".
@Dropbear: You have to understand, in Japan causing a scene is very, very embarrassing. And they fear embarrassment above all else. Yes, it's unrealistic that they wouldn't do anything when molesters go this far, but the fact is, train molestation DOES happen, and often they just let it go rather than making a scene, as long as it doesn't go too far. And that is probably what gave birth to this rather popular genre of porn in Japan.
