Right now there's technically only one path. It's the sharing path. There is dialog for the Netori path, but it's sparce and text only. That's what you're choosing at that point.

The futa thing is even more insidious than just addiction when you think about it. If it ONLY works on girls then it's possible to come back, but if it works on all humans, it's basically an extinction level event. It also depends on how benevolent the futas are. If they are straight up NTR addicts, then it's game over for the binary human race.
Then there's genetics and what happens in breeding.
Do futa genes trump all genes? If so, how does the ovum work in a futa. Is the gender data simply snipped away during conception? Or does the futa ovum allow for all genders the same way a female ovum might? If so, then females are pointless in the setting beyond their futa use.
Male spermatozoa contains the final gender markers. If a futas sperm works like that, then does that mean a futa can have male, female, or futa children? Does it mean that futas only have futas like donkeys can only have donkeys? If futas can have all three, then males are basically pointless in the setting unless futas like males too. If they can only have futas then males are the only way females can be born.
The best head cannon solutions I've come up with is to make binary humans special somehow. But then there's the, 'do futas only want girls' question. Why keep males if they only want females. Making just males special to keep them from going extinct can have story telling advantages, consequences, and chilling results. After all if males are only needed for creating more males and females, it could end up like a chic farm in which most males are simply culled due to not measuring a standard. If males are special, then what about females. Are females only destined to be used by futas? The only way to keep males special without making females not special is to make males super rare. Which leads to commodity (slave) trading. Even fully benevolent futas would become super protective to the point of incarceration.
The best solution would probably to make futas like both males and females. Then they'd have a vested interest in making sure both are around. Then it's just a matter of time before both are extinct if no one bothers making efforts to keep that from happening.
Thankfully, no one has ever bothered writing a realistic futa story. I've made several false starts and I slam into the biology/ethics wall every time. It's easier if gods are involved since most gods are jerks to begin with. Plus 'magic' is a common way to keep world ending consequences from being a possibility.

For a full scene release, I made a gallery viewing room a few posts back. The MC does currently have 3 penetration scenes. The first is if you decided to take Elli's virginity. The second is the Hell Hounds Den. The third is the second phase of the 3 some even. That's all. It's possible to skip all three.
Edit: Wow, I was super confusing. Fixed it!
