Kanna Kamui's best effort at taking care of a bed-ridden Kobayashi results in Kobayashi drinking a magical potion of dubious origins. The potion does little for her health, and instead endows her with an oversized, reeking, and super-potent dragon cock designed for the impregnation of lesser dragons.
Being one of them, Kanna takes it upon herself to have as many of her children as she can-- even if this means blowing out her holes with a cock larger than a torso and having her uterus totally clogged with jizz.
