It's titled "Lustful Desires". I think it was intended to cover the majority of people's fetishes and whatnot, whether it be mild or extreme. And I'm pretty sure the developer didn't intend this to propagate taboo sex stuff. Just trying to appeal to people's pleasures.
So... yeah. I still and would still enjoy this game even the developer decides to put in necrophilia or... whatever over-the-top/wierd kink stuff people enjoy. The suspense of where the story is taking us is more than enough to ignore those not-for-me/distasteful details. But that's for me, in my opinion.
