There are only a few scenes. And the ones that exist, I'm not even sure if the definition is really correct.
I think that's all the scenes. If I've forgotten anything, please feel free to add it. As I said, it is doubtful whether this is really NTR. The forums the definition and the real one outside the forum... let's not discuss this once more.
But I haven't played the current built yet. Maybe there are new scenes that I don't know yet.
In generell, Peasants Quest is not designed for NTR, never was, never will. If you are into NTR, like me, I recommend the game "A struggle with Sin". It's is not unlike Peasants ques but has a solid and good NTR core. This game, as well as Peasants Quest, are still among my absolute favorites to this day. Both games are great, in their own unique way
