Apparently, Arakure really likes to expand on this one year after year, as this is a revised and expanded re-release of a doujin he released last year, which itself had already been the expanded version of a previously released story inside an anthology. This one adds several pages to the story (including two coloured ones) and also improves on the art. Apparently, some dialogue also has been re-written.

The original version of the story in this collection: /g/2320519/44536be8b7/

The Raw stand-alone release from last year: /g/2738400/c9f85c64a4/
The english translation of the stand-alone release: /g/2820487/d6bd960af7/

If curious about the changes (besides changes in dialogue and added sound effects), look into page 26 and beyond.

I think that sometimes they are dissatisfied with some details in their works. Sanbun also did this with Gekkakou no Ori. What matters is that MILFs remain hot and naughty as always.
