There is some variation, but given there aren't many direct relationships that the MC has, alot of it is more NTRS, unless you have that weird mentality where anyone not fucking the mc makes it pure NTR.
Bilia can be forced and suggested into doing sexual acts with a rather brutish guy, tavern owner who does you sexual favors, can start doing sexual favors for others, you can bring I think it's now 4 women from the village to the orc with a dick, you can with enough progression find said orc fucking a harpy female that it is established it is natural that the "strong beat the weak", but it does suggest the harpy feels some shame being found fucking the orc by you. There's a housewife you can watch have sex with her husband, there's an incredibly ditzy friend who basically does free use as a form of marketing for her shop. There is a holy woman you can either make completely into, or have her "feed" off of other males.
All in all there are at least about 12+ incidents of NTR/NTRS, but again out of all of them, I'd consider only 3-4 scenes super into the fetish, while the remaining use the fetish, but in a fun/sexual sort of gag/consequence rather than something to necessarily get off on. If anything the NTR is usually an accompanying tag to a greater tag like sub/dom play.
