I tried this game out and find it to be fairly good, but confusing.
The points to improve on, in my opinion, would be:
1) Have a clearer path to the goals, or even multiple branching paths that can be followed to reach the same goal. For example, the protagonist could take a route involving fetish costumes, group play, and/or NTR before moving to public display and beyond. "something is higher priority" is a poor message when one can't do something. Give a real reason.
2) There should be more gradiation in the expressions and responses of the heroine. If her expression/thoughts can reflect a range from "lay back and think of the empire" to "This is wrong, but feels so good that I just don't care", then first experience should vary from "think of empire" to "grudging orgasm", and gradually progress through "nervously excited" to "I can't believe I'm getting into this" to finally reach "looking forward to it" to "Feels good, don't care". And cumulative experience shouldn't reset for new experiences. If she has been corrupted enough, then new experiences might start out at "nervously excited" or perhaps "a bit anxious but not scared".
3) The money grind is pretty dreary, but only really if you are trying for both heroines. That 1500 for love potions is a killer. And those love potions would be interesting to use on the primary heroine as well. It would be interesting to see a "what the hell was I thinking last night" sort of scene after that.
4) Keeping the heroine around the apartment for 20 straight rounds of sex or so, or keeping her there for all day cycles, should elicit a scene that increases husband awareness and a shame-inducing scene either involving a phone call for an excuse or some face to face lie.
