some girls spanked in sanwa's new mook

I found a sanwa's new mook focused on spanking (and peeing) published at May 25,2015 .

I guess in this book,some girls wet her bet get punished mainly by a spanking like pics above and below...

And an official blog post says this issue comes with a 2 hours DVD which includes movies (on spanking and other punishment ?) .
