Source on this?
This is a short H-manga done by Orimoto Mimana, the same guy that draws the Bakuon!! manga.
The girl on this looks a lot like one of the characters from there, so it was a good material for jokes and shitposting back when the anime was airing.
Here's the link to it assuming you can go past the panda (you should)
