This is fantastic; I snorted beer through my nose a half-dozen times. So good I made an account here just to say so. I see some readers who are getting stuck and thinking there are structure bugs. I think this is not the case, though there are a few places where if you do something too soon out of order, the trigger for that action doesn't register and must be repeated (recycle bin, for instance).
I found most of my issues were user error in doing things out of sequence, because I liked the exploration better than trying for a walkthrough. Follow the sequences (in the quests at top of the screen, not fishing for hints in the scene view menu) and I am sure it works great.
Spoilers, stop here if you like exploring: There are a few places where that doesn't seem to work: it seems if you wait for Lucy to bring the towels, you get another shot at that scene in replay view, but you can't ever get the hallway comment (presumably to Rachel, dunno, haven't seen); and if you let Debbie have Ms Newman as her disciplinarian, you can't get her to L6 (at least I have not been able to yet; Ms Newman can't use the cane, and the +1 weakness bonus to the two best pleasure options disappear, best I have managed is two 8s and a 7).
This is probably true in a few other places, but I absolutely embraced my inner cad. Well, villain, in the story line, and took advantage of Priti (twice) Ruth and Trixie. And likely some others. Did not replay final Lucy as a complete user, and have two Rachel scenes and the holiday events left to go, but 6 stars out of 5. Reminds me of a role play chatboard I was on 15 years ago. Which was a long time, unless you compare it to golden ear.
