Shiranui's Impregnation 2

After the events of Shiranui’s Impregnation 1, Mizuki Shiranui became the servant of the Incubus King, his lover and the mother of his child. But Incubus King has very specific tastes and doesn’t appreciate the fact that Shiranui has been reduced to a cock-hungry slut. Thus he gives her an ultimatum: if she is to remain his lover, she must be able to satisfy him completely. But are all of her ninja arts enough for that?
