A/N: This is a tiny smutty two-shot (with enough plot, I hope), cause I like the idea of an older Naruto and a younger Sasuke who pines after him. Also, shout out to all KisaIta fans out there, it's not going to be explicit, but just to let you know that I enjoy the pairing just as much as I do ItaDei, cause Itachi can be versatile okay. Again, this is an omegaverse story, so if you absolutely don't like it, don't hate on me, tastes differ.

Warnings: A/O/B dynamics, cycles (heat/rut), masturbation, perhaps some OOC.

Disclaimer: I don't own Naruto and make no profit.

A rapid tap came from the entrance door, making Sasuke pause in his step, as he was exiting the kitchen with a glass of water to take it to his room. School sucked and he had a ton of papers to complete for tomorrow, so he sighed irritatedly at the distraction and stomped to the door to see who it was. As soon as he opened, however, his unhappy scowl all but vanished.

"Oh, hey, Sasuke! Is Itachi in?" it was Uzumaki Naruto, his brother's childhood friend and classmate, who went to the same college as Itachi, but studied journalism instead of business. He was five years older and absolutely stunning in a dark green unzipped parka, bright orange sweater and dark blue jeans, his brown leather backpack hanging off one shoulder.

"Hello, Naruto. Yeah, he's in his room," Sasuke felt his face heat up and tried to look casual, leaning on the door frame but slipping along the edge and almost spilling his water.

"Great! Mind if I come in? I just really need to get something from him," Naruto didn't seem to notice his blunder, and now that Sasuke looked at him closer, he saw how flushed the blond was, his breath coming in short pants as if he'd been running to get here. Only Sasuke knew that wasn't the case, and one discreet sniff confirmed his suspicion. Naruto was starting his heat.

"Yeah, sure," he moved to the side in a daze, letting Naruto pass, and felt his own body ignite when the omega's breath touched the skin of his neck as he brushed past him, saying a hurried "Thanks, man," and disappearing into the house. He knew the way all too well, having spent numerous nights at the Uchiha residence. He and Itachi had epic sleepovers, judging by his loud bouts of joyful laughter and his brother's more contained but mirthful chuckles that Sasuke heard from his room across the hall.

The two omegas used to be inseparable, Sasuke often being their inevitable companion, a small energetic kid at that time, who couldn't get enough of their attention. With time, however, he realised that if Itachi's scent had taken on a rather thick, unapproachable note to it, Naruto's had become so heady and intoxicating Sasuke couldn't think straight when he he was close. When he had his first rut last year, he had a very particular image in his mind, while desperately rubbing it off and moaning a certain name into the pillow.

What really frustrated Sasuke, however, was that Naruto still saw him as a child, and he was already sixteen. He was a grown up alpha alright, tall and fairly broad-shouldered (the growth spurt he conveniently hit last year as well seeing to that), with a fully-functioning cock and a thick knot. And he was damn smart, almost as much as his genius brother, Fugaku's pride and joy. Sasuke was perfect boyfriend material, but Naruto somehow failed to notice that, still attempting to ruffle his black locks as he did when he was a child (and Sasuke loved the touch of the delicate sun kissed hand, but he would rather prefer hair play in a completely different context).

He shook his head to clear the lusty mist clouding his mind, and followed in Naruto's step to finally get to his room. Just as Sasuke was going to close the door behind him and concentrate on his studies (despite the hormones he was still a diligent student), he caught the blond's words, as he practically flew out of Itachi's room, "You really are a saviour you know! I'm so absent minded these days, I would've literally leaked all over the bus seat if I went home like this," and he chuckled self-deprecatingly, while Sasuke felt his heart starting to beat a mile a minute, and his face burning with the heat of thousand suns. The mere image of Naruto, warm and slick down there, wet and dripping, all ready for him, so deliciously ravishable, and just across the hall, made his mind go into instant overdrive and his cock grow half hard in a moment.

Sasuke took three deep calming breaths and a sip of water from the glass he was still holding, while his hand trembled a little. This was insane, one of these days he would simply attack the blond if he obliviously kept up this nonchalant enticing act any longer. As he slowly came back to his senses, Sasuke realised that Naruto's light quick steps were going in the direction opposite from the stairs, and the only room that could be his destination was the bathroom. Sasuke's heart missed a beat when he heard the door at the end of the hall open, then close softly. He listened with bated breath to the movements in the small tiled room for a little longer, and after a couple of minutes of shuffling came the sharp sound of the shower curtain being drawn, and then the water was turned on. Naruto was definitely taking a shower. Sasuke's breath now came in short pants but he willed himself to calm down. Itachi was too close and his brother always made Sasuke want to show how well he could handle difficult situations. And this one was really tough.

He reached his swivel chair and sank into it heavily, trying to think of anything but the wet naked body he was dying to taste just steps away. He needed to control himself and get rid of the all consuming desire that was coursing through his system. The memories of great uncle Madara at the bath house that the family visited every month effectively did the trick. But just when Sasuke was ready to get back to his books, a soft knock came on the door.

"Come in," Sasuke knew it was Itachi, but was glad nonetheless that he always knocked before entering. He was just the perfect older brother.

"Sasuke, could you get Naruto a towel from the laundry room, I really must be going now," Itachi looked at his wrist watch, clearly in a hurry. He was going to meet that blue haired burly alpha Kisame no doubt. They met at college and Sasuke was clearly not amused by how fast their relationship progressed, and it was one of the few things he and his father agreed on. Fugaku, while being a fairly reserved and stern man, doted on Itachi like he was a little prince, and seeing him with another alpha put him on edge, especially since Kisame was Itachi's first long lasting suitor. It wasn't that the guy was bad, if anything he had a nice dry sense of humour Sasuke could totally relate to, but he could never be too sure of his real intentions, and he didn't want his brother to get hurt the first time he finally decided to give dating a try.

"Alright, Sasuke?" Itachi called impatiently, ready to take off any moment, pointedly ignoring Sasuke's scowl of disapproval.

"Yeah, whatever," Itachi nodded in goodbye and left quickly. Only when Sasuke heard the front door click shut, the sense of Itachi's words sink in. Get Naruto a towel. Another thing dawned on him then: there were just the two of them in the house. An overwhelming wave of excitement rushed through Sasuke and he practically ran down the stairs, fetched the biggest fluffiest towel from the rack in the little laundry room (never minding that it was his mother's), and rushed back up. When he got to the shut door at the end of the hall, the water behind it roaring in his ears, or maybe it was his blood, Sasuke reached for the door knob and stilled for a couple of moments. Judging by the soft out of key humming Naruto was still showering. But maybe he didn't close the curtain properly and Sasuke would be able to get a peak.

With a loud exhale he pushed the door open, announcing his arrival immediately so as not to spook the blond, Sasuke knew what a scaredy-cat Naruto could be and didn't want him to slip and fall by accident.

"It's me, Sasuke, I brought a towel," he shouted, perhaps louder than was needed, but he was nervous, alright.

"Huh? Ah, thanks, Sas'," came Naruto's distracted reply. The smell of Itachi's shampoo was overpowering and Sasuke guessed he was rinsing he suds from his hair. The only thing that was visible behind the light blue curtain was the shower head and Naruto's left calf, which was glistening wetly and very alluringly, but was nothing new, cause in summers the blond often wore shorts and Sasuke could always feast his eyes on the vast expanse of smooth tan skin.

He turned towards the rack and his eyes travelled to the stool where Naruto's discarded clothes lay in a heap, but what caught Sasuke's attention were his brother's midnight blue knickers and a purple package Sasuke guessed was a male omega blocker. When he was ten he got curious and stole one from Itachi's room, opening it and studying the little device carefully. It had a peculiar curved shape, was rather small in size and had an unusual rubbery texture with a firmer flat round base. At that time he was confused as to how it was supposed to function, but now Sasuke knew that it absorbed omega slick and was like a tiny butt plug, which effectively kept the excessive lubrication all omega produced during heats from leaking and seeping into the underwear. Sasuke flushed hotly at the mental image of Naruto putting the thing in and then pulling it out several hours later, swollen with the deliciously smelling fluid. A shudder came through his body, but he stubbornly ignored it, hanging the towel on a vacant little hook.

Suddenly, something green entered Sasuke's line of vision. He craned his neck curiously and saw a pair of panties lying rumpled on the floor behind the stool. He would've missed them if it were not for the obnoxious colour, they had almost got under the sink and were completely hidden from view from any other angle. Sasuke felt a strong wave of raw need crush over him, practically making him tremble with its intensity. He had to have these panties. He knew they were Naruto's for sure, as his brother detested the colour green, especially one so bright. And seeing them lying there innocently, totally forgotten and knowing that they would hardly be missed, Sasuke acted on impulse, bending quickly and snatching the delicate undergarment from the floor. Then he literally fled to his room, shutting the door a bit too forcefully behind himself.

He could hear his heart pounding heavily in his chest, and for a moment thought he heard Naruto getting out of the bathroom to catch and shame him for his daring deed. But nothing happened. Sasuke stood with his back pressed to the closed door for a couple more minutes, the soft material of Naruto's panties tightly clutched in his fist, then heard the water turn off and the shower curtain rustle, and that put him into action. In a flash Sasuke hid the stolen panties under the mattress and got into the swivel chair, taking the first book he got his hand on and flipping it open at a random page, trying to look as if he had better things to do than carefully listen to Naruto's every move.

He became so absorbed in pretending, as wild thoughts raced through his head, that he almost jumped out of the chair when Naruto opened the door to his room as he knocked, far from being as discreet as Itachi. For a moment Sasuke thought the blond had found out about what he had done, and grew a little pale, while his palms became all clammy.

"Hey, it seems Itachi left already, so I'll be going as well, it was nice to see you. I'll shut the door, good luck with your studies," and with a short wave and a sweet grin he disappeared as suddenly as he came in, not even giving Sasuke time to say goodbye. Still, he breathed out in relief, glad that he hadn't been discovered.

For the rest of the day Sasuke immersed himself in his books, barely acknowledging his mother when she came to say hello - she and Fugaku just returned from their trip to the mall because Mikoto insisted that he needed a new coat and she wouldn't stand another week seeing him parading in the old one. And when she called Sasuke to dinner he only mumbled something unenthusiastic in return, coming down to the kitchen in a kind of trance and sitting at the table uncharacteristically quiet.

"So Itachi's not going to grace us with his presence today?" Fugaku asked sternly, displeasure clear in his voice.

"Give him a little freedom, dear, don't you know how prudent he is?" Mikoto said placatingly.

"I'm giving him all the freedom he needs, but I would rather prefer him having dinner with his family, and not with that-"

"Fugaku! Not at the table," Mikoto looked at the fuming alpha deprecatingly.

"What? It's not like Sasuke is a child any more, and he agrees that that Kisame character is not good enough for Itachi, don't you, Sasuke?"

"Huh?" Sasuke blinked, looking up from his plate to Fugaku, who had his sharp gaze on him, clearly waiting for support. "Yeah, that blue ass brute better crawl back to where he came from and leave Itachi alone," he drawled on autopilot.

"Sasuke! Give Kisame some credit, Itachi chose him after all," Mikoto said disapprovingly.

"He could choose better," Fugaku grumbled but dropped the topic for the evening. "You seem distracted, Sasuke, is something the matter?"

"What?" Sasuke jerked his head at the sudden question.

"That's true, you're not quite yourself today, did something happen at school?" Mikoto looked at him genuinely concerned.

"No, I just... have a lot to do for tomorrow," Sasuke answered, nervously sweating under his parents' scrutinising eyes. Talk of a guilty conscience.

"Just make sure to tell us if there's a little omega we have to be welcoming into the family, alright?" Mikoto said cautiously, and that made Sasuke's eye twitch.

"Mom! It's nothing like that," Sasuke pouted, but would never admit it. He was a grown alpha after all, even his father said so.

When he finally went back upstairs, his heart was already pounding with anticipation. All the time while he was writing boring papers and learning useless subjects his eyes kept wandering to his bed, where he hid his precious trophy. He went to shower, washing at high speed, restraining from touching himself, even though his member already started to demand attention when he ran soapy hands over his body. But Sasuke wanted to save it for when he was in the safety of his room, for the little tiled bathroom had immense resonating capacities (something he had to learn the hard way, and couldn't look his brother in the eye for a whole week).

The moment the door closed shut behind him, Sasuke set his determined gaze on the bed and, turning off the light, went towards it with eager strides. It took him just a couple of seconds to retrieve the hidden treasure. The fabric now became even more rumpled but Sasuke didn't care. He held it in his hand and studied it in wonder, blindingly pulling the bedspread aside and getting comfortable on the mattress. Finally he dared to bring the fabric closer to his face and draw in a deep breath. The rich omega scent immediately invaded his senses, and Sasuke almost moaned, but caught himself in time, biting his lower lip harshly.

He got hard in record time and, rolling to the side, tugged at the washed out sweatpants and boxers to free his stiff length, while pressing Naruto's panties to his face and inhaling hungrily. The moment his slightly trembling fingers closed around his cock Sasuke let out a low groan and started pumping himself savagely, his dry hand rough against sensitive skin, but he didn't care to pause to get the lube. The bottle, stuffed in the lower drawer of his desk, was Sasuke's personal achievement, as he managed to buy it for the first time two weeks earlier with a perfectly straight face, as if he did it all the time (and he was forced to, because hand lotion was a bitch on the bare skin of his head, and he hated how his nether regions constantly smelled of aloe).

The jerks of his hand were erratic but as Sasuke increased the speed and added a little twist at the base, where his fully formed knot swelled to life, he started leaking precome, which finally lubricated his movements, making them more smooth and fluid. All the while he had his nose buried deep in the cotton fabric, and as he took short loud intakes of breath, opening his mouth to be able to taste the inebriating scent better, he held the mental image of Naruto clear and bright in his head. The way he smiled, the way he laughed, the way he looked though hooded eyes when hot or tired on a humid summer day, his brow covered with a thin sheen of sweat, the way he opened his plump lips and ran his tongue across them to gather the drops of ramen soup he loved so much, the way he smelled in heat, oh God the way he smelled was simply divine. Sasuke felt he couldn't hold back any more and had to press his face into the pillow to stifle his desperate moans of pleasure that now escaped him uncontrollably. The green panties became trapped in between, as he let go of them to fist the sheets instead.

Sasuke rubbed his nose and mouth against the source of Naruto's heady scent, while picturing him acting like an omega in heat would in front of their mate. Lying naked and relaxed on his bed, spreading his gorgeous tan legs invitingly and caressing himself to please Sasuke's eye, spreading his butt cheeks, glistening wetly with slick, to show that he belonged to him whole and was eager to take him in. Sasuke shuddered, gripping his knot tightly and squeezing it with steady rhythmical motions to imitate the way an omega's channel would constrict around him when they reached the point of utter bliss. Oh how Sasuke longed to see Naruto look at him at such a moment, to look into his eyes, warm blue clouded with lust, love and adoration, while he shot his thick potent cum deep inside, making sure the omega was full with it to the brim. And then, when Naruto would be riding his high, Sasuke would mark him, placing his claim on the stunning and most kind blond in the whole world, so that their scents would mingle and become one.

At the beautiful picture Sasuke saw so vividly in his mind the alpha came with an intensity that was beyond what he had ever experienced before. As he was slowly coming back to reality, he became aware of the rumpled panties that he bit at when he orgasmed. Sasuke closed his eyes for a moment and drew in the last deep breath before rolling to the other side, and bringing his sticky hand up to eye level. He came so much. Luckily, he brought a roll of paper towels with him from the kitchen, taking it stealthily when his mother wasn't looking. The moment he wiped his hand off and tucked himself in, Sasuke felt a sharp pang of guilt and disappointment with himself. What kind of alpha he was if he couldn't even pursue the omega of his dreams, jacking off while sniffing at his underwear instead, all alone in his room, his parents speaking softly downstairs. This was pathetic. He really needed to take action. To do at least something before it was too late and Naruto got stolen by some low class jock. Oh if only Sasuke wasn't sixteen, he'd surely be able to sweep him off his feet.

So, how do you like it so far? ;)
