This absolute gem was amazing when it was first released and now that it's been put into English, anyone interested in the fetish or even just curious needs to check this out. It may not be an all-inclusive textbook, but it covers almost everything important and is a great thought piece beyond a valuable resource.
Enjoy, my friends, and may this lead to even more believers! Cheers!
Hooray! Almost there! For anyone who has not done their research, there are eight chapters and a ninth spin-off chapter in this series, and 2D Market has done 1-6 with the recent ones being released about once per month. It's been a bit since this came out so chapter 7 should be done soon then we just have to wait for fakku to pick it up and post it, then (assuming all goes well) two more releases until we have the whole collection to hold us over a few months until Futa-bu drops.
