It can be found as DLC for the game on the Steam Store: Anime And Your Life - Hentai (Uncensored)
If the Steam Store page isn't working, you may be able to install it by either clicking the following command or running it directly on your PC: steam://run/985860
Note that this will immediately run the game and start downloading the DLC if possible - you may need to close the game and wait until the DLC finishes downloading for the patch to work.
