You’re not talking about “survival in another world with my mistress” are you? He has minecraft powers and does fuck harpies, but i dont remember any rape or butt stuff. Although yeah, it was definitely a lot better before they started introducing a ton of new characters without filling them out.
World’s finest assassin gets reincarnated as an aristocrat is really good about that first point as well.
And creature girls: a hands on field study (or something like that) is really neat for that second point. It also discusses a lot of biology and politics, although the political discussion is dogshit. Its also super fucked up and basically porn.
