Welcome to the successor of the multporn image downloader v1 & v2 and most downloaders out there regarding "NSFW" material. The NN-Downloader or Naughty-Naughty-Downloader (yes very creative I know) supports multiple sites with their official API (if available), and proxies and it's also portable.
[!NOTE] This projects windows exe is built using Github Actions for full transparency on the build process.

Further sites can be added. Just open a support ticket with the URL to the site.
I am not in any way affiliated or working with these Sites. This is an unofficial project.
*I would suggest you use a customized Terminal.
