EDIT

For some whatever reason I can't link the reference/inspiration for this draw, not sure if DA is buging for links or because it redirect for Hentai Foundry ( but the image is acceptable for DA ) :/ but the image belongs to DrGraevling, I couldn't find it on his gallery here on DA, oh well ....
