BTW for better flavor despite walkthrough I recommend beating the shit out of Asha even though the walkthrough tells you to dis arm her as she absolutely loves being manhandled. in opening scene. (Note: dont forget to toss her away like the trash she is.
I'm a little weirded out by the way you did it, but you bring up something I noticed, too. Some of the recommendations from the walkthrough are actually just flavour choices.
Another example is, when Ain gets punished in the basement. The walkthrough recommends to spank her the maximum amount of times, but the only thing that does is turn her cheeks red. You won't really miss anything, if you decide to not spank her at all.
Also, the scene where Igor and Kateryna are over for a visit has multiple variations, but the walkthrough makes it seems like there's an ideal path. If you go for the recommended choice, you miss out on Zaton getting blown by Emilia and talking about impregnating her.
