Good question, it probably won't count because the MC wasn't involved at the time (Probably going to start a whole thread on the definition of NTR).
The game... You can leave NTR on and never see it unless you realllly fuck up by sending the girls into dodgy situations and you will ger sort of warned. (At least in the walkthrough) If you leave NTR on and loose a fight with Orcs or other things that kill you they will hump your women.
It's easily avoided and it won't trigger behind your back.
I play with it on and in two years of playing I never got NTR'd once
But be warned. If you play with NTR on and later turn it off, it won't work. The game still considers it on
