The game is not completed yet, it has another year at least of development.
This Demo is very outdated, everything has been improved since then including graphics and even the "scene" itself.
Every girl should have 2 lewd scenes for them for final release, some may have more than 2.
Demo 2 which is a huge build of the game will show many scenes and give a very good idea of what the game will be like will be out before the end of the year publicly for free.
There is many builds on the creators patreon right now with very good content that you can access for at least 5 dollars.
