This seems really promising. Nice set up and good English. I'll leave a critique about the full POV version, and you can decide if it's worth taking into consideration.
This could perhaps be a personal preference kinda thing, but I think having too much redundancy in different POVs messes with the pacing. I can see that you made efforts to cut down on showing the same stuff in its entirety, but it's still doing too much "tell, don't show."
We can pretty much already tell what the girls are thinking, more or less. You are already doing this to an extent, but you can use visual cues and the male MC's thought process to give clues on what's going on in the girls' heads. Obviously, since there is a mystery NTR version, you took steps to make these things apparent even without the female POV.
I think the female POV should be mostly for things that are happening outside of the male MC's POV and when it pertains to any lewd stuff. Going over the same scene 3 times when all of them are just talking to each other has pros and cons. On one hand, it can be nice to see exactly what they are thinking. On the other hand, it can lead to pacing issues when the information being expanded upon is not part of a corruption progression or set up AND it's not really giving us new insights on the characters.
There are other games that do basically what you are doing, but with a more measured execution. Watching My Wife, A Promise Best Left Unkept, Swing and Miss, A Perfect Marriage, and various other NTR titles. What they do is to not dwell on the same scenes that we saw in the male MC's side and opt to show new scenes where the female protag goes about their business away from the male MC. They can still do their introspection and monologing about what transpired with the male MC in their respective novel scenes. You don't have to do a play by play all the time showing what they are thinking in that exact moment while talking to the male MC.
Let me just make an example about what I think would happen in the coming update based on what we saw so far in the first release. MC is gonna talk to the black dude in the presence of his two girls. Black dude is probably a bully during his school days or whatever, and there will be some ominous shenanigans. Switch to wife's POV. Same room. Black guy and male MC is talking. She has some internal monologues about why he seems shaken, etc etc. Switch to intern POV. Same thing.
Now let me offer a different way this could be executed. You just see this scene from the male MC's POV. Give some visual cues on the wife being confused or picking up that something isn't right. The intern can do her MC simping thing and try to make him feel better if she witnesses MC being flustered. That can all be done on the male MC side. Then they part ways and when we switch the to wife's POV, it's not showing that same scene. It's showing what happened before or after that scene. She can reflect on what happened during this time.
I'm not saying you didn't playtest or go over your own script, but try to really get into a player's perspective when checking over your work. It gets pretty annoying if we constantly just see the same scenes, even if you shortened it. You can still do scenes like this where we get a shortened version of whatever happened on the male MC side, but it should be used sparingly and only when it's really important.
