New system for Jikage Rising?

I had some feedback that mentioned that the girls are corrupted too quickly, so I've been thinking on making a system that would make the pacing better and more enjoyable (hopefully).

Currently I'm thinking: 

level 1: When you have sexy time with them, it will default to the angry expression, cause you'll only be controlling their bodies. Max lust 25 

level 2: At this level you can seal off their minds, but when you do so, they will break free every now and then and show the angry expression. Max lust 50 

level 3: At this level, when you seal their minds, they will no longer break free, and when you do sexy time with them, their angry expressions will sometimes jump to aroused cause of their weakened wills. Max lust 75. You can command them to wear some outfits that aren't too exposing. Like the school uniform. You can also command them to not masturbate to build up lust. 

level 4: At this level, they will default to aroused. They are like 90% corrupted at this point, and if you bring their lust high enough they will have ahegaos when they cum. Max lust 100 (max) You can have them wear more revealing outfits like having no underwear on or the swimsuit in public.  

level 5: At this level they are completed bound to you. They will be aroused during sexy time, and you can command them to be not able to cum. You will be able to make them wear almost anything in public short of being completely naked. Also they will fight for you in missions and/or corrupting other people.   

Lust modifiers: 

<=25: x1 submission gained 

>25 and <=50: x1.2 submission gained 

>50 and <=75: x1.5 submission gained 

>75: x2 submission gained 

I think this way, it would be more enjoyable as you guys would be able to see the various dialogue variation as well as be incentivised to try out different things! This would also make the grind a bit more interesting I think!

So what do you guys think? Any opinions, suggestion or feedback about this system that I might implement?
