What I have to do to play chapter 1 part 2 as a superior being?
In Chapter 1 Part 1 there's a scene in the library if you're Cultured, where you learn more about Feren futanari. At the end of it, it asks if you'd be willing to touch and give pleasure to futanari anatomy, essentially. If you say yes, you get the Superior Being tag, which enables futa on male content.
