It wouldn't surprise me if the Evangelions canonically included reproductive functions to the extent displayed here, given their base template.

It is a doujinshi, but it's categorized western because it was drawn by a western artist (and read left to right).

Also, the actual work was already posted here. The additional color images aren't part of the original post because they weren't part of the source; those are just images Typo's been posting on Twitter over time.

While you are absolutely right about images from Typo twitter (there is more btw, dunno why uploader choose those 3), previosly uploaded gallery https://e-hentai.org/g/1534762/719350420f/ missing 1 page (page 5 here) and seems to be out of order.
