Oh I already gave her some items too and unlocked lust drafts.
Maybe I didn’t finish the baron’s mansion? I can go downstairs for the threesome and serviced all the customers upstairs and Baron. Am I missing anything else?
Hmm, looks like that's all of the main optional activities which I can remember at the moment. Baron's line will add a single clear point after you talk to the "manager" on the second floor and most likely you've already done it if you can access the basement.
Don't worry about it, you've already beaten the game.
