Succubus Lord 8 by Eric Vall

Jacob and his succubi have defeated Azazel, and now Jacob is the Demon King of the Fourth Circle. But that doesn’t mean the war’s over yet. Now that he’s king, Jake has to figure out how to rule in Hell, keep from being stabbed in the back by the other Demon Lords and Kings, and somehow stay under Lucifer’s radar. There’s no rest for the wicked, and certainly no rest for a Succubus King.
