Intrusion

"Don't go."

"I don't have a choice…" Naruto said solemnly.

"You always have a choice; you don't have to listen to what he wants."

"I have to go…" Naruto glanced at Sai square in the eye. "I want to go…"

"It's too dangerous…you shouldn't go just because he wants you to. It could be a trap or a ploy to get you alone so he can kill you." Sai said in complete seriousness.

"I don't care. I would gladly die by his hand…" Naruto looked downward. "In fact…it would probably be better if he did…"

"Don't say that…" Sai voiced calmly.

"Why not, it's the truth." Naruto started to gather his few possessions into his bag, "there is no point in living without him here…"

"I'm here; your other friends are here…you're no longer alone." Sai tried to reason even though he knew that there was only one person in Naruto's eyes.

"It doesn't matter; no one else matters…" Naruto swung his bag over his shoulder and headed out the door. He was going regardless of what anyone said. It was one of those 'over my dead body' situations and Naruto felt at the moment that was exactly what it would take to keep him from seeing Sasuke…they would have to kill him and he sure as hell was not going to go down without a fight.

"Figures…I don't understand you…I don't understand either of you." Sai mused as he followed Naruto out of the village. "I guess I don't have much of a choice…I'm going too."

Naruto stopped and fixed Sai with a stern glare. "Go back" he ordered darkly.

"No, I'm going with you." Sai said confidently. "You don't have much of a choice you know. I can easily alert others of what is going on and they will stop you, or at least make you pretty damn late…and I doubt you want to take the trouble or waste the time."

Naruto twitched and swallowed hard. He hated the fact that his new team mate was inescapably right and had so easily grasped his mind-set and personality. "Fine" Naruto muttered as he continued to walk.

Sai smiled and followed quietly. It would not be long before he was face to face with the very person he replaced…the one that was bonded so tightly to Naruto, the one that was…and remained…his lover…

Uchiha Sasuke.

They traveled as if time had no meaning…and Sai was sure that for Naruto it didn't. For him it was probably like traveling through a tunnel…desperately trying to reach the light. He had one goal, one mission, one path that would lead to Sasuke. It was obvious that nothing in this world could stop him from seeing that one person.

Sai noted dully the mounting tension and building desperation apparent in Naruto. It was like he was running to the very elixir that would save his life. For the first time in ages, Naruto beamed with life and not the false pretense of normalcy that was his status quo. It was nice to see his expression so genuinely conflicted…Sai couldn't say he was happy or anything near it for that matter, but it was the first time in a long while that he was actually showing genuine emotion.

"He's waiting for us…" Naruto suddenly whispered as they silently moved through the dense forest.

"Sasuke is?" Sai questioned skeptically. He didn't feel the presence of anyone nor the tell tale chakra signal that anyone had even been in the area.

"I can feel him…" Naruto affirmed. "This way…" he motioned down to a cliff face. They moved in closer and soon they both stood before an opening in the stone.

"In there?" Sai looked into the abyss. He didn't feel anything…

"Yep, no mistake." Naruto tilted his head up and sniffed the air softly. "I can smell him!"

With that the blond quickly dashed inside...oddly enough stripping as he went. Sai found it rather peculiar but followed anyway.

Deep within the cave, bathed in firelight, Naruto stood passionately kissing Sasuke. His hand pulled at the dark haired boy's clothes while his other laced through his hair. Sai looked on, intrigued at the greeting. Was that how it worked?

Without too much further thought, Sai pulled off his shirt and joined in…it seemed that was the correct course of action after watching Naruto.

Sai pressed against Naruto's exposed back, dipping his head between his shoulder blades. Sasuke's hand grasped possessively around the back of Naruto's neck but he did not resist when Sai grabbed at his free hand pulling it towards him. Sai used his remaining hand to reach around Naruto's chest and fondle his hardening nipple.

Naruto broke free from Sasuke's kiss long enough to moan and pant out a plea for Sai to stop, but it fell upon deaf ears. Sasuke reclaimed his lips aggressively and he and Sai both worked his pants off his hips. Soon all three boys were standing with the absence of clothes fighting for dominance on every front.

Naruto wanted Sasuke. He wanted him so badly it was driving him mad, but the feel of kisses being traced down his back and the clear feeling of Sasuke's hand being guided by another was driving him over the top. He wanted to top Sasuke as soon as possible, but he didn't really like the position he was stuck in…literally.

Sai had quickly found his way to Naruto's already hard erection and it seemed that Naruto had already found his way into Sasuke who was pressed tightly up against him, his face that of discomfort and wanting. Sai momentarily thought about playing with Naruto's ass that was directly before him, but then again he didn't want to be decapitated by either a fuming red-eyed demon or a Sharingan wielding psychopath so he decided against it.

Sasuke's idle hands had found their way to his own backside and to Naruto's chest. Sai wondered aimlessly if he should do something about it, but then again…it didn't feel all that bad…

"S-sai…" Naruto breathed out heavily. "Stop…with…your hands…"

Sai grinned and moved his hand quicker, nipping at his collarbone as he went. Naruto inhaled sharply, his body tensing. He didn't want to come, he didn't even know what the hell was going on or why Sai had decided to join them…but he didn't have much of a choice now, he was just going to have to go with it.

And go with it he did…Naruto came hard, splattering his product onto Sasuke's abdomen in the process. Naruto rested his head on Sasuke's shoulder as he tried to catch his breath and his composure. He really didn't know what was going on or why Sasuke was not making any effort in stopping the strange three-some. It almost seemed like he was encouraging it since it seemed his hands were busy with Sai while he was busy with Sasuke. It was weird to say the least…

Naruto flushed as he felt Sai rubbing against him from behind and Sasuke moving against him from the front. Inpatient bastards.

Naruto couldn't take it anymore…with a quick tug Sasuke found himself propelled into Sai's chest with Naruto at his back. Before he had much time to protest, Naruto had already pushed him down and thrust into him forcefully. He gasped at the sudden incursion, but soon found out that was a poor decision considering a rather eager Sai was at the ready directly in front of him. With no hesitation Sai pushed himself into Sasuke's awaiting mouth.

Sasuke was not really prepared for such a thing, but he didn't really care. He wanted Naruto to the point of madness. His lust was getting the better of him. He was a jealous and possessive person normally but the intrusion of his replacement didn't bother him as much as it probably should have. It was sure different and more interesting than their norm and it didn't feel all that bad either. As long as it satisfied him and his yearning then he could put up with it for this one time…

Naruto tugged at Sasuke's erection causing him to twitch and tighten his mouth. It was nice that Naruto was making an effort to please him too but if it continued he was going to come sooner than later not to mention the effects it was having on the other pale boy present. Sai clamped onto his head tightly intertwining his fingers in his hair, pulling him forward into him repeatedly. From the feel of it, the speed and vigor…it seemed they were all nearing their climax.

Sasuke came first, clenching as the sensations ran through his body bringing his love to climax as well. He felt as Naruto filled him with warm liquid before sliding out of him gently, his hot breath and labored breathing filled the air and for some reason Sasuke felt much more at ease. In a matter of moments, Sai came too filling his mouth before pulling out. For some that action would have been disconcerting, but Sasuke was used to it. He swallowed easily and finally let himself flop to the cool ground beneath him, exhausted.

He was used to going multiple rounds with Naruto in the past, doing anything but soft sex so his endurance was top notch…but it was completely different when another person was tossed into the mix. There was more surface area to explore, more things that could be done, and much more service to be given.

"Go again?" Naruto finally muttered out from his resting place next to Sasuke.

"In a minute…" Sasuke breathed out hoarsely. "I need a moment to catch my breath you idiot."

"Sorry…" Naruto said barely above a whisper. "I was too rough…I was excited…"

"I could tell…" Sasuke deadpanned. "It's been awhile so I just need some time to recover a bit." If Sasuke had been looking he would have seen a glowing happy Naruto next to him, but he didn't look nor did he notice.

"Was it really that good?" Sai finally spoke up with his head tilted in question.

Sasuke glared and Naruto looked as if he had forgotten Sai's presence altogether, which he probably had all things considered. "Why don't you see for yourself? I'll gladly do you a round and you can please Naruto from the front while you're at it."

Sasuke smirked, pleased with his confrontation. Just because he was allowed to participate didn't mean that he couldn't still hate him. In fact, Sasuke still thought of the other pale boy as an annoying intrusion on his time with Naruto. He went through all the trouble of calling Naruto out so that they could be alone…

"Okay." Sai smiled his normal smile and proceeded to crawl forward positioning his head at Naruto's lap while he practically waged his ass in Sasuke's face.

Sasuke stared at the blatant invitation. For some reason this kid pissed him off more than he could ever say. Wordlessly, he grabbed Sai's hips and pulled him close thrusting into him in the process. Sai jolted a bit but it didn't take him long to adjust and he was surprised that it actually didn't feel bad at all…

Naruto moaned and sucked in air sharply as Sai started to suck him. He fleetingly wondered why Sai was so good at something like that but then Naruto decided he didn't really want to know the answer. He weaved his hands through Sai's short black hair since he didn't really know what else to do with them.

"Sasuke…ah…hmm…" Naruto tried to speak even though he was failing at it. "I…I love you!"

"I know." Sasuke replied sternly as he concentrated on moving. He knew…how could he not? Sasuke desperately wanted to return those feeling, the feelings that he knew he held deeply and securely in his heart. But he couldn't. He was in no position to be able to love Naruto freely. He was a missing nin and the enemy. Naruto would just have to wait…he would come for him; he loved him more than even he himself could imagine. Sasuke just hoped that Naruto would continue to wait…continue to hang in the balance and continue to fervently follow him.

Naruto flung out his free hand and grasped onto the back of Sasuke's neck, pulling him close over Sai's back. "I love you and I always will…" Naruto voiced as he pulled Sasuke into a bruising, passionate kiss. Sasuke returned the gesture, removing one hand from Sai's hip and locking it behind Naruto's head.

"I…love…you too…" Sasuke whispered almost inaudibly as they broke for air before plunging back in, their tongues in a desperate battle for dominance. It couldn't hurt to say it just this one time…

Sai laughed inwardly. He didn't really understand everything clearly yet, but he felt that he had a much deeper understanding of the bond that Naruto and Sasuke shared. It was something that no one, not even death, could break…

An unbreakable love…

Sai decided that it wasn't so bad being the intruder after all...he could get used to the intrusion…in more ways than one…
