It's a porn game so it doesn't need to be realistic. It just has to make sense in the context of the world and story. I hope there'll be no rape at all. It's the most boring and lazy way to write a story. But seeing how Vallabelle is much stronger than Durrak I wasn't worried about it. Now that you mentioned drugging her I hope it wouldn't come to that. But I have to admit it would be an easy way for Durrak to fuck her.
About being a game, ofcouse, thats why i said its impossible to do in realistic way! and yeah im sure its not rape either but about how to do it, if u do remove drug and drunk then be ready for two of most overused and stupid ways which 90% of NTR games go with either:
1. blackmail her somehow and then she suddenly turn to a slut.
2. dev makes her so stupid where the guy can trick her to fuck him for a ritual or to cure a cruse or something (which she is not that stupid "FOR NOW" since she does know what sex and sexual boundary is).
I do just hope whatever path the devs take doesnt suddenly turn her to a slut who let the guy do anything to her in her right mind! if its make her drunk/drugging her it should be done multiple times not just for the first time.
For me personally its more enjoyable when the wife is not a slut and the second guy has to work for it and need to come up with different plans in order to slowly dominate her instead of just seducing her and turning her to a slave to get what he wants from there onward, i think drunk option and drug make more sense since how else can he remove her guard and trick her with his bullshit stories or even seduce her! i dont want her to let her guard down after first sexual interaction and become an slut, it would be fun to watch her get tricked different ways multiple times!
But this is just my taste and we have to wait and see what the dev will do! so far he has done good!
Btw whats ur guys best scenario for her corruption?
