Disclaimer: I don't own Naruto. If I did, there would be a lot more action, and I'm not talking about fight scenes.

A/N: Thank you everyone for the reviews. I'm glad so many people like the stories, since my sense of humour can be pretty out there at times. And here's the third person to walk-in on Sasuke and Naruto. Poor Sasuke and Naruto, will they ever get to finish what they're doing in peace? (Not as long as there are more people to walk-in on them, author thinks, once again chuckling evilly to herself.)

Constructive criticism welcome as always. Also, when you review, telling me what you particularly liked about the story increases the chances of me doing something like it again.

Warning: Crack Pairing Ahead!

Asuma was searching for Shikamaru and Choji. Having already checked all the spots they usually hung out (almost every restaurant and grassy hill in Konoha), he decided to go see if Naruto had seen them, knowing how they sometimes hung out with him.

Seeing Naruto's apartment door in shambles and hearing strange noises coming from the bathroom, he rushed to the bathroom. What he saw in the bathroom shocked him. Naruto was lying on his back on the bathroom floor with Sasuke kneeling between his legs and sucking on his cock.

Asuma didn't know what to do and bolted from the apartment like a bat out of hell. When he finally got over his shock and was able to think clearly, he realized he had to do something. Reasoning that they were Kakashi's students so he should be the one to deal with it (which was in no way an excuse not to deal with the situation himself (Right, author says to herself rolling her eyes)), he decided to go find Kakashi. He headed to the training grounds where team 7 usually trained, knowing that Kakashi liked to go there to read his book.

When he arrived at the training grounds he found that Kakashi was indeed there, perched in a tree and reading his perverted orange book. In his frazzled state Asuma didn't bother with a greeting and just launched into telling Kakashi what he had seen at Naruto's apartment.

"Is Sasuke doing it properly now?" Kakashi asked, ignoring the frazzled state the other man was in.

"What?" Asuma gasped in reply, as he gaped at Kakashi's reply to what he had just told him.

"Is Sasuke doing it properly now? I would demonstrate, but I just used the last popsicle I had to show Sasuke how to do it properly. But then again, I could think of something so much better to use than a popsicle to demonstrate what I mean," Kakashi said, an evilly perverted glint in his lone visible eye as it came to stare at Asuma's crotch.

Kakashi jumped down from the tree he was perched in, putting his book away and approaching Asuma, who was still doing a very good impression of a fish. Kakashi ran his hand down the other jounin's vest, and slipped it into the very stunned jounin's pants, fondling the placid cock until it became hard. He then pulled down the jounin's pants, so that he could proceed with his 'demonstration'.

A/N: Hopefully that wasn't too abrupt an ending, but I thought that would be a good place to end it. And don't worry, that's not the last I'll write about them, after all, the title of the series is Walk-in On Series.

I know some people are probably thinking why Asuma. It's because I wanted it to be a male sensei and I have plans for Gai (Author chuckles evilly to herself). I don't picture Kakashi as being quite so perverted, but him acting this perverted makes the series more…interesting.
