"Harder Kakashi, harder!" Iruka exclaimed.
Some of the elderly people shook their heads and tsked. The younger academy children wondered what was going on. Naruto and Sasuke ignored the disturbing noises while continuing their own shenanigans. Sakura and Ino had discontinued their routinely squabble.
"Ow," Iruka made a small compliant under his breath.
"Do you want me to stop?"
"No, I've needed this for a while now." Iruka hissed slightly as Kakashi finished popping his fingers for him.
"Thank you Kakashi-san."
"No problem Iruka." Kakashi ruffled the younger man's hair a bit, as he had stolen the hair tie, and walked off to find his team.
