There's a Boned Mod, which (in my opinion) only exists to turn the game into an extremely unbalanced mess, and I do not recommend it.
Then there's the Ero Mod, which you can customize freely to suit your preferences in both game difficulty and other stuff, it also does adds more breeding/pregnancy content, meaning that you get pregnant after being creampied by any enemy, and you will give birth to a slime later (unless it was updated to allow for a different monster birth). I believe that
this is the latest release, though i'm not completely sure.
Lastly, there's a discord server specifically for NoR modding, I never joined it but there might be something in there. Here's the
link to the post with it.
