This book is a sequel to Jiyunkyouju Asako. Check it out here:

English Translated - http://e-hentai.fbk.tokyo/index/g/2790909/2724f8ed56/

I couldn't find the proper Japanese raw files of the tankoubon on the web easily (only a compilation).
I do plan to work on a translation of this book in the future, but it may take a while, as usual.
