Good news, everyone! After nearly seven years since tr_23456 first posted those three images, the search is finally over. The name of the book is "Human High-light Film V"; more information on the book is provided here:
http://doujinshi.mugimugi.org/book/1...-light-Film-V/
For the purposes of this part of the forum, there wasn't a lot of AP beyond what was presented seven years ago. However, one of the images was actually a two-page spread; these pages have been rotated and uploaded here for "closure". I lack the ability to properly merge the images together without making it look weird (matching up the lines resulted in a gap between the pics).
If you still wish to see the book for yourself (please refer to the link above for more details on the book's content before proceeding; there's nothing else noteworthy in the book aside from one or two non-offensive, non-process pictures like the, cover page) and you have access to ExHentai, you can check it out here:

[EDIT 07/07/2013]
In the event that you are suffering from Sad Panda Syndrome (unable to access the exhentai link above), please go to the link below. It might not be a solution for everyone, but it's a start for some:
