The game looks interesting and the graphics very nice, so I wonder.. is there at some stage a Linux version, or if not an online version planned? Good luck with further development!
Newgrounds adult games are kept separate, you have to first search 'adult', or 'porn', or 'nsfw'. Then it will ask you if you are looking for adult content and redirect you to the NSFW side of newgrounds. As for finding it in newgrounds https://www.newgrounds.com/portal/view/763159
