these are archived from several places from yahoo groups and other sites i have tens and thousands of these arcived images and all i can say is some are far too interesting to let myself hoard them
37 is an artist "Spark Utamaro" - you can search for him here. 33, 34 and 36 are D2-Girls, a guy whose site is closed now. 22, 25 and 40 is... Kokuyosha, I think, run a search for "Slave Asuka" or "Slave Slave Slave" and you'll find the artist.
11 is lilish, 26 is Girltaker formerly of Deviantart, is 27 is NickLaw-Arts/NickDraw of DA, 28 is DeaArt also on DA, and 42's artist is sometimes known as b. b. or amiba00. D2 girls' real name is Tatsuya Shingyouji, some of his stuff on the net is under that name.
1 is from メタルK (MetalK) by Maki Kouji, 2 is from cowcaw by yaseuma-roll(loru) 9 is from uzusio(http://uzusio04.h.fc2.com/uzusio04_index0_0.htm), his older stuff can be accessed through wayback machine
I'm 99% positive that #30 is by an artist that goes by KonnyKon or Sitryon. It's the same guy. he has 2 DA pages: http://konnykon.deviantart.com/ and http://sitryon.deviantart.com/. He also has an FA page at http://www.furaffinity.net/user/sitryon/ and http://www.furaffinity.net/user/konnykon/. lastly there's a rule 34 page for him http://rule34.paheal.net:82/post/list/konnykon/1 . hope that helps
