Kakashi was hearing noises. Sexy noises.

Noises his keen ears had been trained to recognise.

Someone, was having sex!

Or, rather, two someones. Both male, by the sound of it, and very much involved and vocal.

Now, normally, it would take Kakashi a while to figure out the identities of the two love-birds…

But considering he was in Naruto's apartment that he had recently started to share with Sasuke for previously unknown reasons, he came to the most obvious conclusion…

So, what should he do? Simply finish his search for those scrolls that had gone missing and leave, or perhaps…investigate…?

Gleefully, Kakashi kicked open Naruto's bedroom door, revelling in the alarmed cries of the two boys, and the thump that came from the direction of the bed. He grinned at the sight of a dishevelled Sasuke sitting on the floor (where Naruto had shoved him), looking torn between annoyance and still lingering pleasure.

Though from the positioning the two had been in, he could tell who had topped…

He put on a shocked expression.

"What are you two doing?!"

"Err…" Naruto looked panicked, (he never had been good at telling lies) and he looked desperately to Sasuke for help, but the boy was too pre-occupied with clambering back onto the bed whilst covering his man-hood.

"We…we were wrestling!" The boy looked quite pleased with his lie. Fool.

"Oh, so that's what they're calling it these days..."

"No, no, really! Tell him, Sasuke!"

Sasuke glanced over at him, a glazed look in his eyes, and then mumbled, "Yep…wrestling…"

Naruto nodded triumphantly.

"Can we continue wrestling?"

Naruto glared quickly at him, a flush across his face. Kakashi held back a grin.

"You know, I think wrestling can be done with your clothes on too, you know…"

"Errr…" Naruto's face was flushed red. "Well, you see…"

Kakashi looked thoughtful. "I also think wrestling can be done without Naruto being inside Sasuke."

Before Naruto could say anything, Sasuke sat forward and said determinedly, "Hey! It's not always that way round! Last night-"

"Sasuke, shut up."

"No, no." Kakashi nodding assuredly at Sasuke. "Please, carry on."

Sasuke nodded back at Kakashi, and continued, "Well, Naruto came back from a mission, and he was tired, you see…"

"Shut up!"

"So, I decided to, you know, liven him up a bit…"

"Shut up!!"

"Well, let's just say after I was through with him, every part of him was very much awake, and alert…"

"Why haven't you shut up?!!"

Kakashi looked thoughtful, "So, do you wrestle often?"

Sasuke nodded, "Most nights. Usually, twice."

"Missions?"

"When possible."

"Wha…what…what…" Naruto tried to say something, anything, but he couldn't seem to form coherent sentences.

"Kakashi-sensei, could you leave now?"

Yes! Naruto thought. Sasuke was back to talking sense! Wait, he didn't look finished…

"Someone, hasn't finished what they started." Naruto noticed Sasuke glaring at him, and he glanced down at Sasuke's tent in the sheets.

"Oh yeah…"

Kakashi nodded, and waved. "I'll see you lot later!" He grinned, and poofed away, leaving Naruto to stare.

"Can you believe that? Ohhh, god, what are we gonna say tomorrow? Ahh, it's gonna suck! So awkward! I mean-"

Sasuke whacked him, glaring some more.

Naruto frowned. "What?"

Sasuke hissed out, "Finish what you started."

"Oh…" Naruto grinned at the boy. "Well, if you insist."

The two boys returned to their rampant love-making, unaware that their sensei was planting hidden cameras around their apartment, chuckling to himself.

Ah well, ignorance is bliss.
