Oh… Yes, you need the full version to work with DLCs. Sorry for confusing!
This is exactly that I have in my plans! All of it will be added in DLCs or updates, one or other way.
you know it is hard to find a game like this, glad your game show up in my recommendation and its was 10/10. i hope this game will continue receives update every time! also I suggest if you planning on more story, you should get some inspiration story from ATP Studio and Universal Spanking's channel, their videos are really good at it, might as well create several inspired model from ATP, US's models. :3
