Yeah, and I've been looking through the game files to see when she does it
You know, until you brought this up I'd never noticed it.
The renders tend to have odd lighting issues — note the number of times it's day/night/day/night outside — so my gut says it's just a mistake. But on the other hand, as an old hand at over-interpreting random occurrences into meaningful and deliberate choices, I like the idea. There is
no question that, in both versions, Anne prefers her extramarital encounters to be MC-free when he's present. The scenes are
always hotter, reddening or not.
BTW, it most definitely happens post-first mall visit. The MC fucks her on the couch and her cheeks (actual cheeks, not her ass) flush dark red.
And it happens to Fernanda if they have intercourse on his second massage visit.
Where I'd differ (already abandoning my arcane theories) is that I don't think this is as much an Anne-driven difference as it is a
Mircom3D-driven difference. I've never felt his heart was in a swinging game; I think he wants to see Anne get fucked by as many people and as often as possible. I think player-insertion (wordplay intended), via forcing the MC into sex scenes involving Anne, is "punished" by the resulting scene being less outrageously erotic than the alternative. I don't think that's an accident. And I have a suspicion this would've been made crystal clear during Dre's next visit, which I hope we'll get in 11.
