I went hunting on /a/ archives for the Slavezaku and Slutzaku fics from 2008-2010. Posted what I found up on AO3 because pastebin said the text was NSFW when I tried. I have a feeling there's more to Slavezaku. If someone still has their old CG folders or files, may I please check if the fics are the last available versions?
