My 2 cents:
Now, I went ahead and supported on Patreon, because while I have a pet peeve about below's particular trope's usage, I am a huge fan of harem builders. And this one is pretty good. I like the characters. They are portrayed well by the visuals and dialogue. The story is kind of basic so far, but it's still fun to watch all the interactions play out.
Clearly designed with the (guy gets with sisters and mom) trope, (didn't want to call it what it is on here), But characters are redefined to not be by reader. But the problem is that If they are all just labeled friends and whatnot, why is there a taboo about any of them hooking up? That's what's wrong with using this trope in almost every AVN that doesn't stick to their guns. You should either go all in and call it what it is, (risking getting banned) or write the dialogue so that there is no taboo around it. It's ridiculous. It adds unnecessary, and not worthwhile drama. Just write the characters so that there might be one of those (I know we've ONLY been friends before, but...) conversations. But lose the crap like (I can't think of her that way, she's my xxx...) so dumb.
And if they are, in fact, not related, include some little 2 or 3 line paragraph that gives a 30 second backstory to how each character was introduced to the MC. That makes them being friends and not family more believable. Give them a reason for coming together. Also,
During the party how was Bo flashing her hoo ha all night, and then MC had to remove her panties later? She either wore them, or she didn't.
