Did anyone figure out the reason why the family orgy scene with Kumiko etc. was so long and well done was because low-key it was another NTR scene? The dad is getting cucked. That's why it had effort put into it.
The guy only cares about the NTR plot, which is a shame because he had a good set up. If you're reading this dude, prove me wrong and write something decent for the next chapter involving the core cast, with some creativity, not Sex Olympics "the dialogue of Catherine is so cringe this isn't hot anymore" bullshit.
You're mostly right. But while "Sex Olympics" was filler and didn't really move the story, "Kumiko's house" had much more plot significance. As Sterling becomes a "Dio Del Sesso", he'll have sex with more women outside his own family, and some of those women will already be in relationships/married/etc. Yes this is NTR, but it's specifically
netori, i.e. our protagonist is taking someone
else's lover, as opposed to
netorare when the protagonist's lover is stolen. (Does the audience here have a problem with netori?)
My theory is that Sterling is following in the footsteps of Hunter and Drew; he was taking baby steps for a while, but he's practically become them now. Conquering Kumiko's family was a major milestone on this path. The other will be convincing the rest of his family to have sex on camera for money, which has been teased for chapter 13. This has all been setting up for a long time, Sterling is just finally claiming the DDS mantle. That's always been the story.
