You need the demo/free version of the DLC to enable the original 18+ scenes that were included in the base game. They were removed and turned into the 14 Nights With You DLC alongside the Day 5.5 update.
Thanks for the reply! I figured that out the next day, but I ended up buying the DLC since I had the money for it! Glad to support the game and to see more updates in the future! :)
