Generally patreon frowns pretty heavily on incest stuff, and considering a few of the characters were meant to be... "smaller" before, I'd say it's probably because of being on patreon that it's out of the picture.
I'm not in favor of incest so much, unless we're talking milf and shota type of scenes together, then I'm not against it at all lol
..but I really don't understand the world in instances like patreon's moral stance on that.. I mean I can understand opposition to rape and other IRL morally reprehensible actions that are real crimes.. ( although I don't mind them and like them sometimes in fantasy land(read also as hentai games, porn stories, etc)
..it's just very strange that they are acting it's like somehow morally wrong,(so much so that they make it against the policies). I do agree you probably shouldn't fuck your family IRL, but I don't see it as a moral problem.. more of a choice problem. So I really can't understand I guess. Anyways, thanks for clarifying
