Okay, I am pretty sure I know who the artist is. I used to have a bunch of pics by them but unfortunately don't anymore, though I could try scouring my computer. Some details I remember, if this is the same person:
They have a Pixiv gallery. They draw tons of monsterguys, and a lot of it is (unfortunately) loli shit. Big monsters paired with lolis and etc but a fair amount is monsters taking cocks. Can't remember their ID or name or anything. Maybe someone who knows moonspeak can search "monster" and "loli" or something? They had TONS of pictures in their gallery so it's bound to come up.
