A/N: This part came out sooner than I thought. I hope you thank me for that, lol. Actually this part turned out to be the shortest, which is why it's being uploaded earlier than I had previously planned. But it is probably the most intense chapter out of all of the others. So I hope you enjoy it just as much n_nb

Warning: NARUsasu and really not much else… Oh and this is the last smut chapter, the next one will most likely be a short epilogue.

Disclaimer: I am not going to even bother ¬¬…

UP AGAINST YOU: PART FOUR

Everything was a dark blur and Sasuke could only vaguely remember being carried into the bedroom. He did remember when Naruto threw him onto the bed and the blond had crawled up his body, blowing hot breath over his straining erection and flicking the tip of his tongue over one of his nipples, before pressing their lips together in a heated kiss.

A tan hand slid between pale thighs and without a second thought Sasuke spread them for Naruto. The blond slid his mouth down to his lovers pale neck, and stroked his hard member at the same time, enjoying the vibrations of Sasuke's moan against his lips.

Moving his mouth a bit lower he found the wound he had inflicted earlier. He licked it, the coppery taste making him shudder, as though in apology. But if he were to be honest with himself he wasn't guilty about it at all. The ring of puncture wounds made him feel proud, the only reason being that he had been the one to make them. A mark that was sure to scar and announce his claim forever.

"Moron, what are you grinning at?" His voice was barely a husky whisper but Sasuke could hardly find it in him to care.

Naruto's grin widened, "At how ridiculously sexy you'll look while you scream my name as I pound into you."

Ignoring the furious blush lighting up his pale face, Sasuke turned his head and grumbled, "Shut up and get on with it moron."

Naruto leaned forward licking a pale neck, "Hmmm, what do you want me to do?"

Sasuke growled and glared, "We are not going through this again, moron."

Naruto paused for a moment. He made a damn good point. Naruto didn't think he would last long if he waited any more. Shaking his head Naruto started groping the sheets as he started to move his hand over Sasuke's cock again and let out a small triumphant noise against a pale neck when his fingers closed around a small bottle. Ignorant of whatever his moron was up to, Sasuke grabbed a tan backside and ground their hips together, arching into the others body urgently.

Naruto groaned and braced both his arms on either side of Sasuke's body and almost forgetting about lube as the Uchiha bucked against him, creating delicious friction. His blood boiled unbearably when Sasuke spread his legs further and almost lewdly. Naruto knew that if he were to pull and look at how much Sasuke had just exposed himself he would surely cum like a shameless virgin.

Instead he ignored the primal urge and hurriedly slathered some lube onto his fingers. Pulling the Uchiha into a deep kiss, Naruto slipped a wet finger into his lover. Well, damn, if looking at the bastard wasn't going to make him cum prematurely than feeling the others warmth wrapped tightly around his fingers surely was. Not wanting to embarrass himself and put an end to the long night, Naruto withdrew his finger.

Ignoring the dark confused look, the blond started pulling his chakra downwards and slathered the excess lube over his straining erection.

"Na-Naruto…?" Sasuke's mouth stretched wide open when he suddenly felt Naruto entering him. But unlike the first time, it really felt like he was entering him. All of him. The jinchurikkis entire being, everything that made Naruto, Naruto, was slowly easing and pushing his way into him. Later, Sasuke would realize that it was actually Naruto's chakra that had concentrated itself in the moron's dick, making his muscles relax and contract, more than making up for the lack of preparation.

But right at that moment, Sasuke couldn't think. At all. He could only feel. Feel the way that shocking warmth push its way past his barriers as if they had never existed, igniting him and stroking the fire within him brighter and hotter than ever. Trembling thighs wrapped themselves around a tan body, groaning as Naruto seemed to slip deeper into him.

Naruto gritted his teeth and tried to think about dead puppies to keep himself from cumming. But it was nearly impossible with that unbearable heat gripping him tightly, almost lovingly. And the look on Sasuke's face wasn't helping any either. He found himself staring, wanting to brand that face into his memory forever and never let go.

"Na-Naruto…please, oh god…please, MOVE!" Not wasting any more time, Naruto did just that. HE pulled out partially before sliding back in a long hard thrust. Sasuke groaned and writhed underneath him, the foreign chakra inside of him shifting and burning through him. Sasuke dug his blunt nails into tan shoulders when Naruto started a steady pace, a teasing yet delicious push and pull that had him reeling from the pleasure. Naruto slipped a hand underneath pale hips pulling Sasuke up and closer to him. He knew he had struck Sasuke's prostate when the pale man started moaning louder and without giving it any real thought concentrated on that one spot.

Sasuke found himself spiraling into pure euphoric bliss when that cock started ruthlessly rubbing and grinding into his sweet spot. Naruto leaned down and licked a pert nipple that made Sasuke arch his oversensitive body unconsciously, a long moan spilling from his lips. That hot mouth traveled over his flushed skin, a sensation that was completely different from the exquisite grinding thrusts inside of him.

Naruto slid a hand over the arm that was sprawled over Sasuke's head, lacing their fingers together as he descended towards a whimpering mouth. Sasuke's eyes fluttered closed losing himself completely into the kiss and pleasure that was melting his heart. Naruto was the first to break away from the kiss and they ended up panting into each other's mouths. Or rather, Sasuke was moaning as Naruto's cock continued to push and manipulate his prostate, rubbing it from every angle and Sasuke didn't think he was going to make it any longer.

"Ungh, god Naruto…fe-els so g-good…ah, ah, ahn…OH GOD, NARUTO!"

A particularly hard jab had Sasuke careening over the edge. His body was pulled tight, arching and shivering under the onslaught of his orgasm that twisted and lashed through him. Naruto shuddered as he felt Sasuke's inner muscles flutter around him and bit his lip when he felt his lovers gasps and moans rush past his ear.

When the last blissful waves of Sasuke's climax washed over him, he finally opened his eyes again only to close them again and gasp when he realized that Naruto was still very hard inside of him.

"Shit…Sasuke…"

A loud cry echoed through the room when another surge of chakra flooded through Sasuke. He wasn't even hard yet and it still felt so good. Naruto couldn't hold back anymore. Sasuke cried out again and clawed at Naruto's back as he resumed his thrusts.

This time thought the thrusts were rougher and harder, almost urgent and Sasuke didn't think it could get any better. He could actually feel himself getting hard again and he was drowning, just drowning. In Naruto's scent, in the feel of his heated skin, in the sounds falling from that mouth, in the rhythm of his hips. Everything Naruto surrounded Sasuke and closed in around him locking him in a possessive embrace.

And he hated Naruto for that. For making him lose control like this, for breaking down every wall he had built around him, for getting him caught up in every emotion he had denied himself since he was eight. It was all too much in so little time and Sasuke honestly wasn't sure he was ready for that just yet, but he didn't care, couldn't care, because it was just so hot and ohmygodrighttheeeerree. And Sasuke loved it. Loved it because it was so hot, so good and too soon and so overwhelming, that his ears were ringing with how fast blood was rushing past them. And when Naruto kissed him, his heart swelled to aching proportions.

Naruto devoured Sasuke. Desperate to consume that sweet mouth (that might not have been sweet at all), and claim what was rightfully his. He didn't care if he was being selfish. He didn't care if Sasuke stopped talking to him. Hell, the entire village might go after his balls for perverting the last Uchiha, and he still wouldn't give a damn. Because Uchiha Sasuke was his damnit. And he won't let him go; never again will the bastard escape his grasp. No matter how much the jackass might scream and kick and try to castrate him, Naruto will only hold on that much tighter.

"Mine, mine, god damnit…all MINE!"

Sasuke had no idea what the idiot was going on about but he was screaming when Naruto started slamming into him violently. The bed was slamming furiously against the wall as Sasuke's ass was reamed into the mattress. They were both very close, and Sasuke twisted as orgasm number he-didn't-know-'cuz-honestly-lost-count started to coil inside of him. Naruto wasn't any better, his movements becoming erratic and deeper.

Finally the pleasure escalated and Naruto was more than willing to just let go. He buried himself deep between Sasuke's milky legs crying out just as the Uchiha arched up underneath him gasping for breath. The white hot surge shooting deep within him had Sasuke toppling. Every spasm, twitch and shudder was shared through their deep connection, prolonging the pleasure. Both their names spilled from their lips, deep and husky, following their cries of blissful completion. Above them their linked hands gripped tighter together.

It lasted for several more breathless dizzying moments before they collapsed under the shuddering aftershocks of release. Naruto rolled off of Sasuke's limp body, not wanting to crush the man and for several minutes they just lay there side by side panting heavily. Surprisingly, it was Sasuke who spoke first.

"Holy fuck…" Naruto didn't even have the energy to feel surprised at the uncharacteristic statement.

"Yeah…that was pretty…" Naruto actually struggled to find the word in his foggy brain.

"…Intense."

"Yeah…"

Sasuke turned his head to look at his friend lying next to him staring at the ceiling with a hand resting on his chest. His face was almost blank, but Sasuke couldn't help but notice that there was a soft sated edge to the angular features. Sasuke fought not to blush when it dawned in him that he had been the one to put that expression on the hyperactive ninja's face. He didn't think that now was a good time to get embarrassed after all they had done in the last several hours. Naruto shifted his gaze and ended up looking into dark eyes.

"Hey…" The tan hand that had been resting between them lifted up and brushed a black lock of hair from a pale moonlit face. Sasuke started, not having realized that he had been caught staring. Naruto noticed that the Uchiha had started to shiver, gooseflesh rising out of his porcelain skin.

"What's wrong?" Sasuke sort of wished his eyes wouldn't flutter as that hand stroked his cheek.

"'M cold." He murmured, sleepy despite what he had just said.

Naruto sat up and pulled the tossed coverlet over them while Sasuke just watched. Naruto seemed to hesitate for a moment before making up his mind.

"C'mere…" Naruto slipped his arm under Sasuke and grabbed a pale shoulder with his other hand and gently pulled the pale man towards him. Sasuke didn't protest as he was pulled onto a tan chest. He welcomed the warmth, convinced that the blond was a human heater. Not like he was complaining. He wasn't lying when he said he was cold. It seemed as though his body took the term 'cooling down' a little too literally.

Naruto idly stroke the black hair lying on his shoulder. There were so many things that he wanted to say, but he honestly didn't know where to start. Naruto supposed that "Uh, thanks for a night of wild monkey sex?" and "I had just as much fun shoving my cock up your ass like you did shoving yours up mine" were not good ways to breaking the ice. Then again, it was probably best to post pone the talk for some other date, because Sasuke had fallen fast asleep on his chest if the soft breathing ghosting across his skin was anything to go by, that is.

Naruto sighed deeply, finally feeling exhaustion wash over him. He pressed a soft lingering kiss against the dark haired head, pausing when he felt Sasuke shift, pressing their bodies closer while mumbling incoherently. With a small smile, Naruto settled back into the pillows and closed his eyes, letting a deep dreamless sleep claim him.
