I agree.
First of all, I think that a plot (any kind of plot including the one that is created as a background for a porn game like this) is coherent to the extent that the creator is able to produce his own world, with his own logic where the characters and events unfold following the same logic. For example, if the hypothetical scenario is a male-dominated society, I would expect the unfolding of events to reflect that type of world.
Second, I've seen a lot of people criticize some games for supposedly setting up scenarios that are too "unrealistic". Leaving aside the fact that a porn game does not have to be realistic, many tend to identify reality with their own obviously boring individual environment or at best with the average reality of the average individual. The real world, of course, is much bigger, and you only need to read the news to find out that things are happening, and often things much more horrific than those that occur in the darkest fictions.
Suppose the following plot for a game: a man builds a bunker in the basement of her house in order to lock up her daughter to rape her again and again and force her to have his children. And he is so successful that he prolongs that situation for 24 years... if anyone comes up with such an argument, I'm sure he will be quickly attacked by the "reality police" of the f95 forum. Well, I'm sorry to report that this actually happened. The man's name was Josef Fritzl...Who knows how many similar cases must have happened without anyone knowing? And in the world there are people with much more economic means and power than that guy.
So defining what is or is not realistic is more difficult than it seems.
