How Iruka Found Out...

So, here's how I see this happening...

Iruka and Kakashi have kinky sex in which Kakashi uses the Sexy No Jutsu (because we know Iruka is just too uptight to do that technique). Kakashi ends up preggers but doesn't know quite yet...and then Iruka has to go on a diplomatic mission...or something...that gets him out of Leaf. When he comes back...

KAKASHI IS FAT! Joke, he's preggers with Nei. And so they have da bebe.

.....By the way, this whole picture was a joke. So. Yeeeaahhh...
