This edition cuts the opening short story from original edition but includes extra illustrations and an additional chapter of 30 pages published in another doujin.

此版本删去了原版开头的短篇故事，但是包括了额外的插图以及在另一本同人志中发表的30页番外篇。

Thanks for uploading this @valerria_f.

I see the additional chapter contains futanari on female anal action with cumflation, so that's pretty cool. I wonder where this chapter was originally published.
This Superior Edition has lower resolution, and uses pixelated censorship, sadly.

There's a page in the original edition that references the doijin: https://e-hentai.org/s/38a5355e58/3312745-189, so it probably came out around the same time.
