Well I have to say overall this is a very enjoyable story. The lemon scenes are great. Although it would be nice if you included more interaction between characters, along with action scenes. But meh can't really complain on that part since this is basically a porn story, a good one at that.
I look forward to seeing more of this story good luck on writing it.
Also lol by the time of the fourth shinobi war arc Naruto will be god pretty much.
