"Blarp, finished another one of my old sketches from last year. This is one of the many I have of Varia (the purple haired one) and Queen Mayla (the other one) who is also Mo's mother :O (which is why it's no1, as if I continue to finish these sketches, I won't be able to name all the varia/mayla pictures something witty, so might as well just number them :O )
In one episode of season 2, Varia gets left behind with Mayla and they just have a very nice and touching time togeather... so ofc I started shipping it, and needed to make it touching in other ways aswell! >:D "

Picture n°9 is nowhere to be found afaik, but DontFapGirl has a habit of drawing sex scenes with horses, and such pictures have been removed from HF and InternetArchive, so this may explain that.
