Great questions:
There will be a harem ending with all romances leveled up to maximum; this creates a big polycule of sexy and very willing women. I am interested in exploring a dynamic epilogue that responds to the events of your week, allowing you to see the eventual outcomes of various decisions. However, this is a potentially large effort to implement, so it will take a big back seat to main stories and expanding the library of sex scenes.
Once the more niche sexual content is developed, it will be at least labeled, although following suit on some other games, I may make game options to turn on and off some types of content entirely, or make it skippable.
