Interesting find...

Cool! A book that's a collection of wet and messy Japanese art, a collaboration between several artists. Several stories about ladies having fun in deep mud. At the back it's got details about the various artists, with links to their twitters and other sites online.
Turns out that is the second collection/issue, same person has uploaded the first issue as well: https://e-hentai.org/g/1134772/491e9cc1c6/
There's a few pages of stuck and sinking stuff in that one, a story starting on page 26.
And the comments on that page have a link to a pixiv page linking to all the artists' pages.
