would be nice to see more content with Tia and the Orcs on NTR path...This kinda monster NTR is very rare(it's rape but the way it is written...the girl comes to acknowledge that the orcs are superior stock by herself which is pretty hot corruption(inevitability is big part of NTR as a whole genre and here this point is very strongly accentuated by the fact that Tia is presented as someone that is probably naturally predisposed to liking Orcs because of the story behind her birth and orc genes, ergo no matter what MC does she will always prefer the orc deep down, it is unavoidable). like a hostage falling for the kidnapper, really dark and very depraved.), the only game that comes to mind is Noxian Nights minotaur ending. Her and her mother seem to be into that too.
@Chyos Dunno if you wrote entire subroute with this in mind but if you haven't...this is the reason why it's hot. I have a feeling you nailed it completely by accident though, no offence haha. Just that most people don't really understand all these NTR flavours, it's already a lot if they know the distinction between netori, netorase, netorare etc, but the ideas behind these fetishes are too much to understand for most.
Penny's route was also dony pretty well, you could say it was just classic netori, nothing over the top, kinda like vanilla ice cream, it's pretty basic but everybody likes it. If there was one thing lacking that would probably be the scenes themselves, the corruption is largely unfinished.
Frisha's NTR route could be a classic father figure NTR, where the wife/girlfriend of the son gets stolen by the father, how good it actually becomes would depend how well you emphasize the difference between the son and the father, comparing the cuck with the bull is also big point of NTR, which as a genre is often very devoid of logic, because, there is little reason for the young healthy woman to prefer an old man over young dude, so there must be some well written reasons for her to sway that way. Usually it's the difference in sexual prowess in one way another. Materialistic reasons aren't that great, it makes everything more seem like a business transaction, no emotions or any depravation involved so that ain't very erotic, just plain and simple.
Didn't think much about other routes...as for love routes they are dumb and simple as they always are, you help out the damsel in distress most of the time, she falls in love and happily ever after with some escalating dirty talk. Now that I think Imarwyn is pretty much the same as Tia but another way around, she likes superior human stock deep down as opposed to an elf, it could be written in such a way too. For her corruption NTR path I guess it would be natural if at some point that elf lord showed up. But unlike Tia where Tia prefers orcs, here Imarwyn would prefer the protagonist of course.
The girls at the monastery are pretty basic, the one with the southern accent is just kinda cute and stands out writing-wise. Her corruption and NTR probably would be best if it was some basic cliche...maybe childhood friend from southern parts coming over and it can be done like Penny's? The young blonde imo, the best way to proceed with her route would be giving her impregnation fetish, since she was so averse to getting married and pregnant....her having that kinda fetish seems like a natural corruption. In case you had no good ideas for her...
The old gilf woman though...there were so many different subroutes but she seemed like a natural for some sort of BDSM, domination route because of her oppressive behaviour towards her daughter she was presented as natural sadist, so that kinda thing seems like a natural way to write her.
Other girls and routes are pretty basic for the most part too. Who else worthy of note was there...Mia's NTR route is in general rather weak, Aidalyn should have been written as way more appealing for her than our protagonist. Because of her not being written as someone that seriously attracted to Aidalyn the NTR with him is extremely bad and the Netori also feels weak because it just don't feel like there is that big emotional connection between Mira and Aidalyn so what sort of NTR? They also just become friends with benefits no big deal about anything. In my view something should have happened during the ritual and Aidalyn should have been made more menacing for the NTR or Netori to work here. Her pure love route on the other hand is plain and simple, not much to point out there.
Gwen and Sabrina's NTR route would probably need to involve some heavy futa action, I never understood that very well but this also seems like a natural development.
The stuff with Dasan, probably best to play with the hierarchy aspect, since he is the tribal chief and all. Maybe a Corruption/NTR centered around some shamanistic rituals and strange customs makes most sense. You can really go crazy with the customs, can come up with anything, like dunno a custom where chieftain selects a woman and breeds her for a whole week until she gets knocked up, pretty obvious(for scenes could just peek inside the tent every day or two, could do that any girl and it would be good netorare wrap up. For netori protagonist could have some sort of breeding competition with the chieftain and win by large margin breeding all the girls...ideas are plenty.
I only wanted to mention Tia in the post but ended up writing such a long wall, sorry
Right...there would also need to be a lot said about the animation and sound department but I will give it a rest...just that audio tracks and climax are very important in porn. Good audio can affect how the scene is received big time and climax speak for itself. In many scenes climaxes are spiritless and no special audio during important scenes(only anal scene with Mira at home comes to mind, not gonna say the audio is on point there but as an example, that important turning points in the route would be better off with some nice audio to accentuate the vibe better)
