Really liked the story, but lost it and haven't been able to find it. There's a guy who grew up with a twin sister and a wolf-girl as his servant. He has to escort a princess somewhere, they get attacked, and he uses his magic to save them. Then he goes to the capital and gets married to a noble girl who drinks a lot and has an attachable penis. Then he starts his own religion based on domination and submission. He impregnates his sister so that if he dies, which he does when he falls from a building, he is reborn that way. Any help?
