I didn't understand the reasoning for the 2 separate versions of the game before, but I've since seen a thing someone linked where the dev said the ntr version contains the full game and both routes... though I still don't get why then the option to double-team the mother at the start of the game has been removed from the NTR version if there's an alternative version specifically for more vanilla players that don't want to see that kind of stuff.
As for my sig, no it's not black girls, haha... it's not really darker scenes either there's very few games I'd really count as being at all dark anyhoo... I guess games that still feel a bit pervy despite having being fairly desensitised to it all / ones that are just great or something, might cover it, but it doesn't really... and I'd ignore it anyway, it needs swapping up but I've been waiting for stuff to come along that would inspire me to do so and I could unreservedly put in there to replace some stuff.
