Theres also something to be said on the fact that "Futa" as we know it, especially futa ntr, is a simple fetishization of trans womanhood, with futa in particular angling on the idea of the trans woman as an invader. (Probably not the place to have this discussion, but oh well.) Dominant trans women do exist, but that is kind of watsonian in this case. This story does have that fetishizing element (of course, its a porn game, its practically about fetishes) but you could charitably read it more in the light of Lily approaching them with actual friendship on a more equal playing feild, (both, arguably, on account of being a woman herself) as opposed to Kane's treating of them like servants, who he never feels any need to actually understand as people beleiving he is inherently owed their admiration. But, again, a bit watsonian, as this can also lean toward the invader concept.
