II. (Naruto, Age: 16-ish)
"Naruto-sensei!" The chorus of voices yell from outside their hut, one tone outraged and the others seemingly half-hearted. Suddenly, the door slams open, and the sight of his three students greets him, Konan leading the charge. Her eyes narrow at him in anger, and Naruto absently wonders what he's done to upset his female student this time. Behind her, Yahiko is barely stifling his laughter, and Nagato keeps glancing between him and Konan nervously.
The bluenette brandishes a familiar orange book at him, and the entire situation becomes clear. "What is this, sensei? We've found a ton of these books in your stuff. Really? How can you possibly go on and on about Jiraiya-sensei being a pervert when you read his books? And you own every one of them?"
"I mean, really? What kind of respectable adult—shinobi, even—reads this kind of stuff? And you're our sensei. We're impressionable children."
"If you would just let me-"
"Have you no shame? It's completely deplorable, not to mention-"
"-explain, I'd tell you that Pervy Sage sends them to me without asking. I have no say in the matter."
"-you'll give Yahiko ideas..." His explanation pulls her up short, and Konan's anger quickly morphs into embarassment. She glances at him and then the others uncertainly before coughing into her hand. "Well, then... I apologize for making assumptions, sensei."
"That's alright. I'm not mad about that." His easy-going expression sharpens as he levels them with a Look. "I do, however, have a problem with you going through my things without permission. Not only do I dislike having my privacy violated, but I also have some rather dangerous scrolls in my possession. Do you have any idea what could have happened if you'd have activated one of them?"
Guilt-ridden and repentant, the trio apologize sincerely. Rubbing the back of his neck sheepishly, Yahiko admits, "It was my idea, sensei. I was just curious about what kind of cool stuff you'd have. Nagato and Konan tried to talk me out of it, but I wouldn't listen. And when Konan caught sight of your books..." He left unsaid the obvious aftermath.
Smiling again, he ruffles the boy's hair. "As long as you've learned your lesson..." He trails off expectantly.
As one, they reply, "We have!"
"Good." Noticing the slight tension remaining, Naruto cracks out a teasing smirk. "Aww, man. How awesome of a sensei am I? I don't even have to do anything to teach you life lessons." Clapping his hands together once and nodding, he declares, "Alright. That's it. From now on, my cute students, I won't teach you jutsu. I'll just wait until you guys mess up and then wring a lesson out of it."
Cue the groaning. "Sensei."
