I say skip to whatever part you feel like writing. If it be the NaruSakuIno, so be it. (smut? WHERE?!) It almost sounds like this'll turn out to be a 'Naruto x everything with two (4) legs', though I doubt that it'll go that far. As for how to fix it, DAMN THE OOC, WOMAN! GET TO THE PORN! not that i am for even a second saying that you must/should sacrifice plot for porn. Erm, we know that Kyuubi is a horndog (fox), so who's to say that he'll go on a rampage when he takes over? Or, does Neji have to seduce him into not attacking Suna? (He should get a medal for that. No, really!) Would he need Gaara's aid? (One doing his duty to his village, the other honoring a mutual-aid treaty...)
A thought: If the Bijuu are gods on earth, what would Yamoto's ability to control them be considered? and what would Danzou be, a wolverine? (wait, they regenerate. scratch that) If daddy-dearest is the Godslayer, I'm guessing that he offed the last Kyuubi incarnation. Who did he off, some random KyuuAvatar? or someone specific, like Sarutobi-sensei?
