Kakashi sighed in resignment as his student's fingers slowly crept over his scalp, tugging and pulling at strands right at the roots. Why Sakura was obsessed with his hair, he didn't know, but trying to stop her from obsessing was beyond his capabilities.

"Sakura, I think I need to tell Tsunade about this fixation of yours."

Wiggling fingers paused, and then her hot breath was on his ear. "You wouldn't dare, Teacher."

And then her fingers started again, pulling and tugging his hair with obsession, looking for something no one knew but her.

He sighed again, and closed his Icha Icha book. "Actually I would. I really think you need rehabilitation for this addiction of yours."

"You are going to send me to rehab for wanting to play with your hair?" There was that hot breath on his neck now, and he took a moment to banish the unbidden thoughts that really should not be thought about his pure little student.

"Yes, I am."

She laughed softly, and started to gently comb her fingers through his hair. "You know, Teacher, I think blue would look absolutely smashing on you."
