It has nothing to do with NTR being in the game, or the girls becoming 'slutty'. It has to do with the inconsistency, and the girls becoming more and more slutty without player input. If it was like this from the beginning of the game, no one would bat an eye. I'm not even talking about revealing clothes, I don't really give much of a shit about that. It's more-so their behavior and attitude. Neither Kari, nor Lois, were anything like they are now at the start of the game.
I have no problem with an OPTION for the girls to become more liberal with their outfits, or becoming whores, or whatever the case may be. I just wish it was optional, since for the most part all content like this was optional at one point, then it just suddenly wasn't. I have no idea if this is due to workload, or pressure from patreons, or whatever the case may be. I do know though that, it sucks for those of us that were enjoying a game that was once something fun and full of choice, that is slowly devolving into a sudo kinetic novel full of increasingly slutty "love interests" and paths that hardly matter for certain characters anymore. Where our choices don't matter all that much, and things are being forced by the plot.
At this point, might as well just default all love interests to a slut or whore path, and turn it into a full fledged sharing extravaganza, where the MC just let's them do whatever the hell they want, and they can run around wearing nothing at all.
