Solid update and a few points where I'll try to avoid spoilers. Overall the story is very well written and paced! Just a specific point or two about a certain event that was both hot and very important in the overall story of Anna:
First, I have been verbally supportive of this dev and game the entire time. IMO, it's in the top 3 best adult VNs currently out there. However, I have only verbally supported because I don't give a single dollar to a dev until I see the dev finish at least one good title and begin another. Too many flakes and milkers out there.
This update has reached a point of no return on the Chris path where we will now learn what this dev is about. It's hard, definitive line that even an average storyteller must know cannot be undone. The story will either progress realistically from here on between them or the dev will pull a milking, L&P-like move where Anna immediately backs away from Chris.
It's a bad sign if on the Chris path Anna suddenly wants to pull away or we just don't see those two for a while.
Why is this the case? Because you cannot do what they did in this update and go back from that. What he did, what she allowed and did...and then said...that's an absolute delineation line. There is no going back (good for us on that path).
The time to realistically back away or cool the situation off is, at the latest, the pictures. She sends some, she gets a dick pic and MAYBE wakes up the next day determined to not go further. You could maybe do it then and have it not make your eyes roll so hard they're looking at your own brain, lol.
Now? No. Can't go back. In fact, realistically they should have done more. IRL that gets to fucking real quick. They fuck IRL of in that scenario. Period, end of story. Yet, it's a porn story so I'll grant that it stayed at what it was.
Still, that's too far to go back. If the next update or interaction with them is Anna backing off or cooling it down for a bit...I can't say I'll trust this dev writing or plan for this story.
Secondly and very importantly, this does NOT mean Anna has to become the town bicycle starting in the next update. I'm not saying she and Chris did what they did and now Anna has to be the town slut or anything.
I'm only saying that her relationship with Chris (and David by proxy) is forever changed. You cannot do what they did and go back to anything like it was before.
On that playstyle/path, the story for those two from here out has to be set based on what just happened. EVEN IF Anna suddenly got some definitive proof that David didn't cheat or didn't get a BJ from that woman, you cannot do what she did with Chris and go back to normal. To do so is to have no idea how actual people behave and think.
To do so is L&P-level "Sophia acts like a slut for the 100th time before suddenly deciding she can't...only to do it again an hour later with someone else or even the same person" bullshit. To do it is to also make Anna a weird psychopath.
I hate to say it but I have cheated once and it's partially why I even found this site. I'm still paying for my fuckup as I lost someone I actually cared about over it (and other things I stupidly did, admittedly). I haven't even tried another relationship since. Anyway...
When you cheat it doesn't happen all at once. You slowly flirt for, in my case, months. Then you have a moment where it outright crosses a line, usually overtly going from flirting to talking about fucking. Presented as a joke or not, it goes from flirting to specific talk of each other hooking up. From there it's just a matter of time and when you finally fool around you don't just stop. The whole "stop...we can't..." before one of you turns and leaves is not how life works Iol. It just isn't. That's movie shit. It's not real.
In my case and many others I've learned about, when you're cheating with someone you've known a while it takes both parties over. You stop thinking of consequences and that's the problem. The excitement (and guilt) becomes part of the cheating. It's only when you've both lost the person you cheated on that you slowly become bored with each other and you stop...before trying to get the back the one you betrayed in the first place.
I get that "porn logic" is a thing but this story has been written very well so far and I'd hate to see it fall back to the stereotype BS just to prolong it.
Again and so I'm clear, her path with others can be whatever the dev still wants or will make up in the future. Anna and Chris specifically have crossed a line that cannot be uncrossed. The time to do that was before the latest event. It would be horrible writing to uncross that line.
Anyone else (Rob, Jake, Hank, etc) is fair game as that line hasn't been crossed yet.
Third and finally, in the cheating/unfaithful route Anna shouldn't even be thinking there could be some conspiracy with David. She has tons of people, strangers, showing her evidence and telling her that David cheated. Well, with common sense you'd reach that conclusion. No actual woman would get half as much proof and question if their man cheated. To her, realistically, it's a better story when she has those moments of "fuck it, he cheated so fuck him and I'm doing what I want"...because that's what actual women do. It just is. She shouldn't be confused or unsure if he cheated. She has seen and heard enough to be 110% sure he did.
So Anna has not just crossed that line with her husband's best friend but she did it largely due to believing David already cheated and doesn't find her as attractive anymore.
She has zero reason to want to even think about uncrossing that line she crossed with Chris. Realistically, the only thing left is to sed her slowly lose her desire to even lightly protest. Those weak, fake "but we can't...we shouldn't" replies as they're fooling around should slowly fade with time. That's how far it's gone.
Anna simply has no reason logically, emotionally or physically to suddenly decide to not go forward with Chris on the sneak.
TLDR:
You cannot do what Anna and Chris did and ever go back to what it was before between them. By "before" I mean before he stepped into the bathroom. That act and her act changed their relationship forever, in a story that makes any sense whatsoever.
It's a bad sign if the dev even tries to uncross that line between them. Others? Every path is still open for Anna to go any which way the dev desires. He's simply taken Anna and Chris to a place that cannot be logically withdrawn.
