We will likely not going to dabble into niche fetishes like pregnancy, NTR or Non-con.
I am, DEEPLY, offended, you would pair it with Netorare. For shame. Niche? NICHE!? What are you, Friedreich Niche, author of Thus Spoke Zarathustra? How do you think your parents made you, huh? With some Nietzche practice???
In all seriousness, if you are aiming for a vanilla experience with your game, I don't blame you. Just don't compare it to more extreme fetishes like NTR. It's not even a matter of pride, it's just so much more generalized so as to not even be properly comparable.
I didn't compare anything in my comment, only gave examples of things that I consider niche enough (with no comment on HOW niche) and therefore, I will not do.
Furthermore, the only reason I even bring NTR or Non-con it's because they are requested enough for me to want to push that information out there every time I answer.
