The free 18+ DLC is hidden in Steam for me and I even can't install it with the direct install link, Steam tells me that the item is not available in my country :( Is it possible to get the DLC somewhere else or get a Steam key for the DLC?

Does anyone now the secret code? I tried to find it but there's no hint

I went through the whole game, but for some reason they didn't give me an achievement Catgirls
