Sorry pal I don't know about the artist, i found these pages in a Aco thread on 4chan while looking up for updates on chapter nine, apparently they're leaked or something.
Looking at other parts of the comic, it is VERY common that the sex scenes end up being a dream, or somebody's imagination, or simply not happening at all. So, what's up with that, why does the author dislike the characters fucking at all? Why even offer the option, then?
@AlexDKZ I do not think the author has something against sex scenes. As there are some that are apart of the story. Though yes most are imaginary and never really happened. As the Space Drow story is a story within a story. As one of the characters is spinning a sci-fi tale. If I recall right. Though each time they go off being rather dirty. They get punished.
So it is in other ways. It is a bonus part of the story. It can be skipped and nothing be lost from the plot. Though do keep in mind. Sex does happen still.
