Let me get this straight, so PK gives her porn a on-going story? What's the purpose of that? I mean that means people who don't read potn but read the basic plot are missing chunks of the story?
I don't think Floraverse has a basic plot anymore, it's literally a collection of shitty short stories that PK makes for herself.
And these three stooges weren't even the 'main' characters to begin with, they were side-characters that the original mains, Min and Cress encountered. But then, you know, PK got a massive boner for Beleth and the original plot ("these seeds will save the world...for some reason") was basically dropped like a stone.
So now you get these 'character building' comics which offshoot from the sfw comics (somewhere I think) that are also porn. This would be fine, you can have comics that are porn. But the issue here is PK is doing both sfw and nsfw stuff, with the characters from both sides cross over with no limit. (Reminder of PK and company's shady viewpoints and handling over minors and exposure to sexual content.)
But as you've said, PK's 'model' can cause people to miss out on chunks of "story" if they don't want to read the porn. It's almost like she's punishing people for it: "Oh you want the full (sordid) experience, WELL, you have to read my personal wank material for that. Oh you don't want to? Too bad, no refunds,"
And speaking of wank material:

We have an update. Amdusias suddenly has a massive and rather terrifying rape-face. I feel no sympathy or attachment to Beleth whatsoever, but this is still a child (piloted) character being offered a role in a BDSM fantasy by an adult. God PK is fucking disgusting.
