I've been looking for this Hentai doujinshi ever since Fakku changed their system. I recently found out the parody of the doujin is from the hentai Black Bible but I still haven't been able to find the one doujin I've read a whole ago. It's a more recent doujin probably draw in the past 7-8yrs if you look at the art style. I don't remember the characters that were involved but there were some gang banging race/action between this blond girl and this blue haired girl.
