A question.
Does the way "villain" abuse a girl correlates with amount of pleasure you as a player get?
SNIP
So does the upping of degradation of a girl actually adds the ntr-effect?
If I'm understanding your question right, not really, personally. I mean, the exact method / style in which the guy works the girl over can obviously get into other kinks, and I have my own preferences on those, so they'll appeal to me more or less on that basis. But I don't feel like they directly impact how I feel about the NTR aspect of it.
The one thing I'll say there is I do feel like it can impact how much my suspension of disbelief needs to be pushed. Like, for example, if it's a more extreme result of a girl almost completely changing within a matter of days, it's easier for me to go "yeah sure that makes sense" if it was achieved by e.g. constant sexual orgasm torture / denial and forced mantras about her new role and pain when she expresses resistance, rather than just a good ol' hard dicking from some magically good cock.
Kinda related, jumping to the 'writing' discussion going on:
There needs to be at least some story to it, otherwise u could also just jerk off to images on rule34 imo. Character relations are important, this can be achieved not by a wall of text but key moments that exaggerate that (Boy Hero Ken is a good example, some routes of scars of summer too). Of course, that is just my opinion at the end of the day everyone has their own, but I feel like NTR just really starts to hit when character relations are established, otherwise it feels just like normal porn.
Yeah, I'm definitely with Knight here (and it seems like others as well). I've said this before, but a (the?) critical part of NTR to me is the girl being stolen, or in other words, the bonds of an existing relationship being at the very least warped, usually outright broken. You don't really get to appreciate that without having at least some understanding of what those bonds were like at the start. (Generalizing way out, this is because well-done contrast can make things incredibly erotic!)
Similarly, NTR doesn't *always* need to involve 'corruption' / a noticeable personality change in the girl, but it often does, and that too really requires having a baseline to contrast against.
