I Can Has ROFL Nyao? Or, The ROTFLMAO of the Catgirl

[K sai]

After Iruka realises that there's no way he can avoid having Naruto taking him out during the genin test, he contacts his old team-mates for help...

Iruka shrugged. "I have no idea. But that's not the issue. I have to face my students tomorrow for their final exam. I can handle them, but – one of them has a highly unusual technique that – immobilizes me," he said in a defeated voice. He gulped his sake.
Kotetsu shrugged. "Is that it? What? You want us to help you train or something?"
"In a manner of speaking," he said as a dangerous light glinted in his eyes. Iruka's fist clenched and the saucer in his hand shattered. A drop of blood escaped his clenched fist. Izumo and Kotetsu looked unnerved by his actions.
"Uh, Iruka—?" Izumo began to ask hesitantly.
A large wallet was dropped onto the table, making a heavy thud that announced it was all but overflowing with money.
"In there is a significant part of my life savings. You have permission to spend every single coin in order to properly prepare me for this technique," Iruka said in a deadly calm voice.
"I still don't know what you want us to do," Izumo said, while Kotetsu picked up the wallet, hugged it to himself and began cooing to it.
"Sexy-no-jutsu! It is a powerful but flawed technique. I know how to defeat it!"
"Sexy-no-jutsu?"
"Yes! A technique developed by Uzumaki Naruto. Its purpose is to defeat perverts by overwhelming them with unexpected lust therefore producing a sudden lack of blood pressure to the brain, causing faint and/or dizziness. I am ashamed to admit that it can defeat me. But no longer will I allow it to do so. I will surpass my limits!" he said finishing in a loud yell that startled Izumo and Kotetsu.
"In order to defeat this technique I must surpass every single shred of prudishness I have. I will become the ultimate pervert!" His eyes turned dangerously to his comrades. "And you will help me. You will take me to every tavern, brothel, strip club, geisha house you can think of! You will expose me to the most debased, vile, kinky acts imaginable! You will immerse me in levels of sin and debauchery heretofore unthought-of!"
There was a deadly quiet power in the air that was shattered by the sobbing of one Hagane Kotetsu.
Izumo turned to his friend. "What the hell is wrong with you?"
"I have waited – so long – for this day!" he managed to say in between bouts of sobs.
Iruka merely looked down in disgust at his comrade.
"Idiot."

The rest of the omake is just as amusing... Iruka Sensei - Chapter 3
