I just recently read a dojin called Code Geachu, does anyone know of anything else like it (for any series)? I like reading funny parodies of my favorite characters but I don't like it when thy suddenly turn into porn.

Gensokyou only translates Touhou doujin, pretty much safe

Gaku gaku animal land translates quite a lot of doujin, so you might want to check them out. They also have warning (on theri website) on the content, so you can skip out those NSFW releases.

I just read One Day Yuno-san Found a Mysterious Notebook, its was hilarious.
