There is one with Lamia in the paid version; it was commission work.
You can watch it by using an item that you can find on the bookshelf in the player's home.
You can purchase here on Itch.io or in Steam you can view all the content without any issue. the patreon version difference is mainly gallery room and cheat related.
i want to have an equal amount of content for the girls so i dont think there will be more vore content since it were commisioned in the first place.
However in patreon i do accept content commisions for the game.
