No one knows for sure.
On the author's Discord he did have a potential NTR prototype, but there hasn't been any news about it for a long time.
NTR is quite a polarising topic in AVNs, some people love it, some people loathe it, other are okay with it depending on the type. My personal feeling is that "most people" are okay with sharing their girl with another girl, particularly if you are allowed to join in and make it a threesome. People seem to be a lot less keen on real cheating and/or being cucked out (although there are plenty of people who like that too, and if you do, more power to you). Personally it doesn't do a great deal for me, but I don't hate it.
Graphically, I think what you have (in the current game) is about as good as you are going to get, you might get incremental improvements, if models are updated from one version to another, or the creator improves their skill at posing, or if they can afford better hardware which make rendering scenes quicker.
Of course sometimes someone will play a blinder and pull something out of left field, one creator (Novel) made a game called Void's calling, it was pretty basic stuff, maybe even a little on the primitive side, but now they are making Boundaries of Morality, which is visually stunning by comparison, so we will have to wait and see.
