Clothing is already fully underway now. Last update she showed some cleavage, this update she's wearing that tank top all the time, and even dressed up in a too-tight sexy nurse outfit.
Also, giving a deepthroat is... slutty... especially vacuuming that big dick - that falls into morality.
Finally, the exhibitionism she did in front of her husband, whilst a crime lord treated him like shit is immoral... and orgasming from it 13 times is even more immoral.
What she did, and enjoyed doing, was deeply immoral. It's not just the acting like a criminal that forms part of the morality, it's how depraved she was in this version that was immoral... and a big change.
Most of what you wrote there all play into her morality becoming corrupted sure. But most of it was still not by choice and is a part of this psuedo-blackmail / punishment that Vargas is inflicting on Luna, because of Aiden's failings. The exhibitionism and nurses outfit with both forced on her by Vargas, and if you read her mental status, you would know she was pretty opposed to it the entire time, thinking only of how to get Vargas to shut up and quit embarrassing Aiden. Her deepthroating Vargas was also a part of that ploy to get him, Vargas, to shut up. Obviously she wouldn't have attempted that before, but, in my opinion, that is tying into her physical corruption a lot more than her moral one.
The clothing thing has only really just started and I think will develop quite a bit more. Vargas didn't tell her to wear the tank top all the time. Just requested it and left it up to Luna if she would or wouldn't wear it. She then proceeded to wear just the tank top of her own volition. There is also the set up now for her to go back to the clothing store and change her outfit again.
Aside of all of that.
This is the first I'm playing this game and I've noticed a pattern with the choices, as rare as they are in the game. The top choice is always "voyeuristic." Basically Aiden getting the pieces to eventually put together that Luna has been having sex with Vargas. But they're also doing the most to inhibit the Nox Syndicate from progressing and Vargas from consolidating power. Whereas the bottom choices always seem to keep Aiden ignorant of what Luna and Vargas are doing, but also tend result in better outcomes for Vargas' faction.
So to me: the "good" ending is bringing down Nox, but Aiden ends up losing Luna fully. And the "bad" ending will be Nox thrives, Aiden probably dies, but does so in the belief that Luna was continuing to look out for him even if we know that isn't the case.
And now a quick little review. I really enjoy this game, the story has been engaging and thankfully most of the characters have, usually, good reasons for when they're stupid or incapable rather than stupid and incapable for convenience's sake. i.e. the poison for Aiden, Vargas' supreme ego, etc. I do wish however that since the choices are rarer, that they tend to have more impact on the story or dialogue. Only a few times was there a significant dialogue difference. Kama living or getting killed should probably have huge ramifications and I think it was only something like 10 lines of dialogue that was changed in how Nevin went about it.
