Probably a molten hot take here, but if you think about it objectively. There's no difference between your sisters body for instance, and a random girl you know who's similar. Ergo, in my opinion. Incest means fuck all, all that matters is if there's a connection there, it's legal where you are, and everyone is willing and not being coerced somehow. If that's the case, I couldn't care less if you sleep with the person down the road or a family member. As far as would I? It would depend on a lot of factors, including are they my type, are they truly interested? Is it legal etc. If everything checks out, family or not, bloodline or not doesn't matter. We only find Incest as disgusting because society taught us to be disgusted by it. Because think about, like really think about it. WHY is it you think it's not right or disgusting? What makes family different? Is it because they're family, or is it actually that those in your family just aren't your type?
