If you take away my subjective opinions, then yes, basically there is no point in having a good story in a “fuck game”. But then again, there are plenty of “fuck games” out there that don't have much of a story. But yes, you're right that in the absolute sense, in the basic genre that this game is, the story is not important for the average user. But personally, I think that trying to release a game like this in this genre is quite courageous from the creator.
And I totally support him, because he wants to tell his story no matter what the users think. I think it's important that the creator doesn't let himself be influenced (from what I know, I wouldn't want to say that he's never been influenced, since I'm guessing from what I've heard) by those who would like his story and his game to be treated like any other game in the same genre, and that he adapts to their different expectations.
Which to me again makes it more unique and more appealing. The creator wants to tell his story, and maybe his personal vision for games in this genre. And not the story and style of play that anyone would expect. You can't compare it to other games in this basic category, for me, it's radically in the category of adult games, but not in the category of porn games.
But yes, unfortunately you can't satisfy everyone, some will love it, like me, and others will hate it, it's ineluctable.
