If you enjoy this, I implore you to support the artist by purchasing the work here if you know your way around dlsite: http://www.dlsite.com/maniax/work/=/product_id/RJ128518.html or to support them when the work goes up on the English dlsite. By the way, I decided to romanize the title since I thought the title would translate awkwardly but it would be roughly something like "Record of Breaking the Female Teachers" (However, I find that 牝 seems pretty derogatory when referring to human women so that it might be more like "Bitch Teachers").
Note: Page 19 and 38 are exactly the same. However, one was included in the text version and the other in the textless. I just kept it as-is.
Pages 2-20: Text Pages 21-39: Textless
1/24/14: It seems that GFF had forgotten to include page 16 when uploading the set to DLSite. GFF then subsequently decided to publish the file publicly via pixiv and the file has been added to have a complete set.
eliana: Hmm... strange. The original file doesn't seem to include a page 16/16T. I wonder if the numbering is just off or if the dlsite version is missing those files.
Edit: Actually, the file was, indeed, missing. However, it was missing from the entire work in general and GFF has provided the file on pixiv. Added to the gallery.
