I might look into adding more scenes for Lily in the future. But it'll probably be after I finish act 2/before I start act 3. Kind of like a polishing off act 2 update. And I was thinking about adding a scene when she's at work too and you visit her.
As for surprising the girls with the sex dungeon/what that room is, I kind of already started that in the next update/v0.12 where Lenya wants to know what that room is, but the MC decides she's not ready just yet to see inside
