Warnings: If a 7 year gap with a 23/24yrs and 16/17yrs old is something you don't feel okay about, please skip this fic!

I do not have a beta for this fic: If you would like to fill that role please send me a PM. Most of the fic is written. (like 3.75/4 of the other chapters for this arc, there might be more way in the future)

Disclaimer: This was of course inspired by the Naruto Manga, which I do not own. I'm not sure about what the legal stand on is owning a name, or a grouping of names. Though some characteristics of their name sake are similar, the characters are different than in that Manga. Also I will not be making any money of this, so there is also that.

Forward:

1) thanks for tuning in again. Many of you requested a long angsty fic. My initial intent for this was to make a one shot, but when it comes to telling a story vs a quick sexy thing it made more sense to put it out in a few chapters. Warning: this is significantly different than the other two chapters.

2) I'm less into the overbearing use of demeaning words like "slut" so FYI it gonna be way less when we do get back to smut, but it's something they are into so it wont be absent. I already know my characterization is a bit OCC to begin with, but idk if you will feel they are OCC from the first two chapters also. We didn't really get to see much so there isn't much to go on. Moving into full story mode changes things... so oh well...

3) This comment has a story spoiler maybe read after?: I also know I made some conflicts that could have been fleshed out more, but I decided to focus on the primary issue, the age gap instead of letting the story get outa hand complicated. Also about the age. After I was nearly done, Sasuke's age still bugged me at 16, so I decided to send him abroad for a year to help close that gap, hence this chapter. Hiding a relationship(or whatever the thing they have is) for 1 year vs 2 years is more feasible for the two. FYI, though I've written the legal age as 18, many states in USA only have 16 as age of consent. I guess it's up to you have you feel about certain age gaps.

4) I apologize for my spelling errors. Hopefully I have caught the sensei vs sensie, if not let me know and I will try again.

5) There was a student in my school who did take AP chemistry as a Sophomore or maybe it was AP bio? Either way, he had to get special permissions, I don't recall the exact detail of how he worked it out but he did. Since it is so rare that's why Naruto didn't even consider it possible Sasuke could be so young.

~Junior year~

-n-n-n-n-n-n-n-n-n-

It didn't take the young science teacher long to figure out that his sexy student was a bit younger than he anticipated when the boy neither lined up nor had his name called at graduation. Aside from the electronics teacher, who Naruto had a ton of dirt on, no one else in the school was the wiser about the two incidents of the previous year. The summer had gone by fast. He had taken a brief trip with a good buddy down to New Orleans, the shops were fun and the night life great. But the few one night stands he had managed didn't satisfy him the way his student had.

Naruto hated how his curiosity about the Uchiha had gotten the better of him when his name wasn't called off at graduation. He immediately had logged onto the school website and pulled up his record. Not only was the kid just starting his junior year now, but he had a summer birthday, making him one of the younger kids in his grade. Few seniors graduated at seventeen as there would be only a few with summer birthdays. So it had been a safe bet that Sasuke would have been eighteen and legal had he been a senior. As it were, even if he had been a senior there tango was illegal, not just a risk to Naruto's job.

In this school year he asked the students to state their grade level while he did the first roll call, not because he had plans to hit on any of his students, but more so because he clearly had not realized the demographic in his class in his first year of teaching. There weren't any sophomore's only a few juniors and mostly seniors which left him wondering how Sasuke had managed to be in the AP class the previous year. He couldn't exactly go around asking the office staff without piquing their interest.

The first week past and then the second. The young Uchiha hadn't bothered stopping by. As much as Naruto would like to see him, he also dreaded such an interaction. There wasn't anything there emotionally, but there was definitely something there sexually. It wasn't a barrier easy to put back in place once breached. It had to be done, now it had to be avoided. At least until the kid was a legal adult.

Naruto accepted it for what it was after the blow job. Sasuke was clearly under a lot of pressure to get good grades. While, Naruto was a horny teacher who was being an momentary idiot. He was also under the impression it was only likely his job was on the line, not a prison sentance for being a pedofile. No matter how many times he replayed it in his mind, he couldn't excuse his actions the second time. He had found himself having zero self control even at the hint of desire from Sasuke. Hell, he knew he had goaded Sasuke on for it after the first one, and secretly had hoped that Sasuke would infact, 'put his ass on the line.' The first time was clearly out of desperation of Sasuke to get an A. When the second interaction was so artfully staged by Sasuke, Naruto didn't see the point in resisting something they both wanted. This yeah, as Sasuke hadn't shown up in his home room, it was clear Sasuke had already had everything he already wanted.

Naruto had never had any complaints. If any of his former lovers were unimpressed they had kept it to himself. As for Sasuke, it wasn't like the kid had anything to compare it too. That or he had been lying about it being his first time. At fifteen, it was likely true he had been a virgin. It wasn't like other gay friends of him hadn't had a little one time thing with a gym teacher or a priest. Sasuke's curiosity had clearly been fulfilled and he moved on. Given how vocal and needy the teen had been, he had likely found someone else to fulfill those needs during the summer, meaning he didn't need or want Naruto anymore. Who was Naruto to keep the school's heart throb's attention? Being rejected sucked, but that didn't mean Naruto could turn off his attraction for the guy, But now that he knew how dangerous it was, even to just have a little fun, he would have chosen to forgo any future possibilities even if the opportunity presented itself.

The biggest issue was that Naruto kept letting his mind wander back to the interaction. He spent every day of the week in the same room. Imagining his young Uchiha student stretched over his lab bench wasn't a difficult fantasy to muster up, nor the one against the door, or on the floor, or back on the desks, by the windows, despite being a small room there were too many fantasies to flesh out in his mind. Though he felt guilt after every time he touched himself at night to the fantasies, at least a fantasy was legal and wouldn't land him in jail. In time it would pass. He knew he was prone to long term crushes, he had held onto his crush for Ino for 8 years. But finally as he matured and explored his sexuality he realized that he was more interested in males than females and they were able to build a close friendship.

As the school dances approached he volunteered to monitor the young kids. He had expected Sasuke would have found a date, but never spotted him. The staff generally wasn't caught up in the student drama, so it wasn't until mid year when he caught Sakura passing a note that he had a clue as to why he had never run into Sasuke.

'Rumor has it Sasuke will be back home for winter break.' The note went on in some detail of where he would likely be spotted and which days, but Naruto wasn't about to go chasing the guy around town. He crumpled up the note and tossed it in the trash.

"Gossip is for outside of the class room, miss Haruno. I'd think my TA would set a better example. If I catch you or Aoi passing notes again it will be detention for a week."

-n-n-n-n-n-

There was a light snow on the last day of classes for the year, but nothing to worry too much about. Mostly it just made his class room cold so he kept on his astronomy club jacket throughout the day.

The majority of the students had rushed off to drive, catch their ride, bus, or walk home ready for the break. Naruto took a peak out of the large bay of windows in his classroom. The parking lot had calmed down for the most part. He needed to grade the classes finals and get the final grades posted before he left, but he also needed to watch that the snow fall wouldn't force him to stay the night. He was about half way through the tests, having done a good many of them already during lunch, but the after noon classes were still to be graded.

Grading tests was not particularly fun. To start with it was tedious, next it was frustrating figuring out what the failing students had been thinking and trying to get them some points, and third they made him think of Sasuke. The majority of Sasuke's test were perfect, or near perfect scores in the second semester. Since Naruto didn't reveal the exact number of points each test would be worth it made it more difficult for Sasuke to target the 95% he needed to barely stay out of the A range. Instead the student had skipped out on turning in some homework assignments. It irritated Naruto, the level of manipulation the teen had accomplished. The utter complete understanding he had had of the content to do so. Naruto had always been good at the subject, which is why he perused it in college, but Sasuke's level was just irritating.

Naruto flicked off the last number on the page he was grading and wrote 'three sig figs!' He tosses a 14/16 grade on the page and then grabbed the next test.

"Hn." The noise from the door drew his attention away from the equilibrium question. Was he hallucinating?

"Sasuke?" Naruto felt an instant rush of panic and lust.

"Sensei." Sasuke stayed casually leaned against the door allowing Naruto take in his appearance: a black draped t-shirt which had a large cowl neck and a odd fan like symbol near the left pectoral, off white pants, fancy gold watch, two studded belts with one hanging from the other.

"You about to walk down a runway?" Naruto teased.

Sasuke tossed the heavy coat he had been clutching in his right hand onto a desk. "Got in from the airport earlier, thought I'd see if I could catch some classmates before they headed home."

"Everyone is pretty much gone, except a few other teachers. I doubt you forgot classes ended at 2:35. It's already. So what might you be doing here?"

"Hn." Sasuke stepped into the room, making his intention to stay obvious.

Naruto hating the silence desperately searched for a question to fill it up with. "So uhhh, flight.. Where have you been this year?"

"Did you miss me, Dobe?"

"I noticed you weren't around. Close enough."

"Europe. Not like it matters where. It's not here." Naruto felt a panic as Sasuke started to walk over closer.

"Nah, that's like super amazing. Had you signed up for a student exchange program or something? Where in Europe was the school?"

Sasuke seemed a bit uncomfortable at the simple questions.

"What you get in trouble for something and you were sent off to boarding school?" Naruto regretted his phrasing, had Sasuke gotten in trouble for them having sex? No that couldn't be it, he would be in a jail cell by now if that was the case. Had Sasuke been caught during the summer fucking someone else? Naruto's stomach flipped over with nausea at the thought. It wasn't like Naruto hadn't found some warm bodies himself, he had no right to feel jealousy.

Naruto's lab stool was high but not so much that Sasuke didn't tower over him when Sasuke reached the desk and stood in front of him. Naruto took in the new height Sasuke stood at wondering how much taller he would still grow. The kid had likely been working out too or had joined a sports team at his other school.

"It's family related, so it's personal. Could we skip the questions and go straight to the sex?" Sasuke's eyes linked up with baby blues pleading with desperation. 'Ok. Naruto, keep it cool. Do not grab him and and smash your mouths together. Jail is a super shitty place to spend Christmas.'

"My dick being in your ass is a little personal don't you think? I usually like to get to know a guy before, take him out to dinner. .. check his ID" Naruto mumbled the last part.

"Hn"

Naruto wanted to get off this topic as soon as possible. "Your classes going well this year?" .

"Are you offering to tutor me if I need some help? I wouldn't mind some extra help with sex ed." Sasuke's lip curled up. It was clear Sasuke had a single purpose in being there and wasn't about to get distracted.

"That's not gonna happen." Naruto spoke very slowly making sure his meaning was clear.

"Really?" Sasuke was about to reach out to touch Naruto, but his phone started to ring. "What?" He answered the phone a bit harsh. Sasuke's eyes grazed over Naruto body several times as he listened to the caller. "Tonight? I have plans." A sparkle glinted in Sasuke's dark eyes as he took into Naruto staring at him, then he winked. 'Who the hell is this cocky bastard? what happened to the needy asshole?' "Father, already making a ton of other demands on my time, he can stay out of my personal business." Sasuke huffed out. "Mother insisted? Fuck." His dark eyes seemed to flash red with anger. "Fine. I'll be there." Another short pause. "I'm on my way now. I hate you."

Sasuke grabbed a sheet of paper and then grabbed the red pen out of Naruto's hand..

"Uh, everything ok?"

"Idiot."

"I may not be your teacher, but you still owe me some respect." Naruto stood up clenching his fists. He now stood higher than Sasuke and used his larger size to try and get Sasuke's calm facade to break.

Sasuke only grabbed lightly at the button second from the bottom of his shirt contemplatively. "I've been looking forward to showing my respects to you for months, but I'm afraid it's gong to have to wait a bit longer."

Sasuke penciled down a few numbers onto the paper. It wasn't a mystery that it was Sasuke's phone number. The raven haired kid grabbed Naruto's waste and made to kiss him, but Naruto turned his face to the side and found Sasuke's hot mouth sucking on his neck instead. His stomach coiled and his groan perked up. Seriously, Sasuke left for six months and he was suddenly so different, so demanding, so much sexier. But that didn't change Naruto's resolve. "Woah, Sasuke, slow down."

"Can't, have to leave." Sasuke pressed soft kisses over the skin he had been abusing moments before. His eye gleamed with pride, Naruto was pretty sure he had a hickey now. At least he had the next week off so he wouldn't need to hide it from his students. "Call me, I'll have some free time over the weekend. If you're lucky I'll answer some questions after."

"Fuck you Bastard. You're sixteen. Why the hell would I bother with you?"

"Hn." Sasuke tightened his grip and pulled their bodies flush. Naruto wished he didn't have on this stupid jacket so he could feel the contours of Sasuke's chest. His breath got heavy. "Because you like a bad bad boy, and you know I am one and I'll let you fuck me however you want." Sasuke leaned back in fortifying his marking as he sucked on Naruto's neck. Naruto closed his eyes and soaked in the feeling. Sasuke groin pushed into his own and he could feel exactly how much Sasuke wanted him. But he had to stop. Naruto firmly grabbed Sasuke's hips stopping them. Sasuke pulled back looking at Naruto with questioning, glaze covered eyes.

"You're sixteen." Stressing the importance to Sasuke.

"Hn" Sasuke leaned in for another attempt to kiss Naruto, but found firm hands keeping him from doing so.

"You are sixteen." Naruto firmly spoke leaving no question as to where he stood on the issue.

"You didn't have a problem fucking me when I was fifteen. What am I too old now?" Sasuke waited a moment for the answer, he wasn't going to like what he heard next.

"You are such a fucking asshole." Naruto slammed his hands down on the desk, breaking Sasuke's hold.. All he wanted to do at that moment was punch Sasuke. How dare he? "For your information, I've found plenty of older experienced men to fuck in the past year. I barely even remember our time together."

"Bullshit."

"GET THE HELL OUT."

Sasuke's face clearly soured at the mention of Naruto fucking anyone other than himself. "Fine. I have family matters to attend too." Sasuke removed briskly walked over to his coat to grab it. Naruto stepped out from his desk a little, almost chasing after the Uchiha, he still wanted him. It didn't matter how much of an asshole the kid was. Maybe it even turned him on a little. It took all of his sanity but Naruto crumpled up the paper and tossed it into the waste bin. He was sixteen, there wasn't even a choice in humoring this fantasy. Sasuke's eyes narrowed. "I've learned a great deal about getting what I want, Mr. Uzamaki and I want you... inside me again and from the look of you, you want it too, legal or not. I'll be seeing you." Sasuke left the room.

Naruto looked down at the front of his pants . "Shit."

Bonus~ how Sasuke met Karin

-s-s-s-s-s-s-s-s-s-

Sasuke looked over the white table cloth to his date, 'Karin.' He was only sixteen it wasn't like his mother could seriously marry him off already.

"So Karin," a smooth baritone voice asked, "I understand your family is in medicine? Any interesting new developments we should be aware of?"

Sasuke glared at his brother, Itachi.

-10 min ago-

"Thanks for the ride." Sasuke got out of the black mustang and slammed the door.

"Tsk. I'd think you would treat your future ride kinder."

"You keep saying that, but I haven't had those keys in my hand since my birthday. What the hell are you doing getting out of the car?"

"Otouto, Mom told me I had to make sure you actually went on your date."

"Ok so I'm here, so leave. "

"And let you bail out so easily. I'll introduce you to her."

-the present-

"Looking for some insider trade tips? Sorry Itachi, I'm not so privilege to know such things, nor did I think this date was about espionage. ." Sasuke rolled his eyes.

"Otouto." Itachi smiled. "It's your turn to ask her something."

"Hn."

"Don't let that bother you," Itahci smiled. " Sasuke tends to have his own language of grunt. I'll teach you how to interpret. First make an accusation. Otouto, if you don't speak to your date she might think you are too entranced by her looks and have clammed up."

Sasuke's eyes rolled then looked off to the side.

"Well, Karin, I hate to tell you this, but I don't think my little brother is really into you. Our mother I'm afraid doesn't understand his romantic tastes."

Karin didn't seam distressed in the least. "It's, alright, I'm more interested in someone else than your brother." Then again he was always over shadowed when his older brother was involved.

This was why at all cost he needed to keep Naruto away from Itahci. Sasuke understood the score. Though his brother was far harder to read, and Sasuke assume he was asexual, a good many people could make that assumption about himself. Their interests rarely diverged, so if Itachi got a glimpse of his chemistry teacher it would likely be game over for Sasuke. "In this case Itachi had one huge advantage, that was he was four years older. Aka the right dating age for Naruto. There was little chance Naruto would resist such an offer from Itachi. The only comforting thought was that Itachi would resist the temptation if Sauke asked. But that would mean confessing his interest to his meddling brother. Despite his constant teasing and butting into Sasuke's business, Sasuke knew Itachi was a true brother. They wouldn't hurt each other on purpose. Itachi, though in an odd way, looked out for Sasuke.

"Sasuke. Are you into someone?"

"Hn."

"Oh..hohohoho. I like her, she's direct. Also, I didn't know you were into someone little brother." Sasuke and Karin's eyes both snapped to Itachi.

Karin gleefully looked at Itachi. "What I didn't see anything, he didn't do a thing!"

"He blinked."

"Every one blinks, all the time." Karin protested the evidence.

"But you gave a 'yes I am into someone' blink." Itachi smirked.

"Itachi." Sasuke gave out a warning glare.

"And you really hit the nail on the head. So otouto where is this crush from? England?"

Sasuke took a calm breath out.

" From Konaha then."

"Karin, is your hair naturally that red color or do you dye it?" Sasuke introjected.

"Konaha it is. Is the girl at the school?"

"OMG he nodded his head back and forth, that was a no?"

"You saw it, good good." Itachi smiled. "It means we got something wrong. Oh and there is the warning glare." Of course Itachi already knew,but he had to share.

"She's not from the school."

"Oh, otouto, still scared of that little thing?"

"Itachi I'm leaving." Sasuke got up.

"Sit back down and I'll give you the keys."

Sasuke sat down and pulled out his phone. The hell he was going to let Itachi unravel all his secrets in front of a stranger.

"Oh my god, Sasuke you're gay." Karin burst out.

"Itachi, I swear I'm going to kill you." Sasuke kept scrolling through his facebooktryingto will the other two people at the table away.

"Sasuke don't worry about it." Karin's lush voice put him at easy a bit. "It's not like I wanted to come out tonight either, but since I attend Konaha high, your mom thought it would be great for us to meet. I won't give away your little secrets."

Two pairs of midnight black eyes flashed over to her. Neither expressed much much, but the older one seemed to have a great amount of joy, while the younger a good deal of fear.

"So," Itachi started but Sasuke cut him off.

"So she likely knows the person. Fuck."

"So little brother, do you want to continue the guessing game, or are you going to tell us?"

"How about this, Karin I'll tell you my crush so long at you keep it a secret from my brother."

"Deal." Karin nearly shouted drawing the eyes from every table around them.

"Tsk." Sasuke smirked, finally feeling he got one over on his brother. Maybe Karin could be a good partner for him after all, just not in the way his Mother envisioned.

-s-s-s-s-s-s

After the traumatizing dinner with his brother, kind of revealing his deepest secret to a stranger, and Itachi then asking her to go with them to a movie next week Sasuke needed some serious distressing. He flipped up the lid on his laptop and clicked on his favorite website, The Kohnah astronomy page. He went to the events tab, then over to Birthdays. Under it was a bunch of pictures. Next to October 10th one of Naruto. It was his favorite picture available on the web of his teacher. Shit, he should have taken some with his cell phone this afternoon, but that might have been pushing it.

Naruto was standing with his hands in his pockets. His favorite this was how the blonde's blue eyes seemed to almost glow, he often found himself staring at them for hours. The photo was well framed, cutting Naruto off just below the groin, making it close enough his facial features were still easily viewable, but there was enough of his body to appreciate the man's hard muscles. The photo was likely taken during the summer rather than on his birthday since he had on an orange wife beater. There were blue jean at the bottom but Sasuke didn't know if they were pants or shorts. If ask Sasuke would say the clothing choice insulted his eyes, but somehow Naruto looked good in orange. Then again Sasuke was Biased, he liked his blonde in anything, or preferably in nothing. He had searched around, but hadn't found any evidence of his teacher paying for school via nudy pics. On one hand, he would have loved to have found such a treasure trove, on the other hand he was glad the old trope wasn't too common. That man's body was for his eyes only.

Sasuke got up, went to his bathroom and grabbed a hand towel then went to checked the lock on his door. The towel was placed carefully onto the beda bit below the pillow. Sasuke grabbed his laptop from the desk to placed on his night stand making sure the coconut oil he kept there was still in easy grabbing range. Tossing his clothes into his tall laundry basket as he took them off, he then went to the bed laying backside down. He put some of the oil onto his hand and started stroking his near limp cock while turning his face to the side so he could look at the photograph. He concentrated on the way the tan skin tasted in his mouth, how he had left a mark. A gasp parted his lips as he remembered Naruto's reluctancy to push him away. In his mind deep blue eyes watched him as he touched himself. The restrained older man still fully dress would watch with hungry eyes, goad him on in his miniterings. "That's it long strokes, you know I like to watch you touch yourself." Sasuke gave himself slow firm pumps. The blue eyes would grow hungrier and hungrier. Naruto would lower his hand, unable to contain himself touch his own erection through the taught fabric of his blue jeans.

Sasuke imagined himself getting up. "Please can I suck it?" He would plea.

Naruto would fick his fly open and the long appendage spring free. Sasuke immediately would take it in his mouth. Imagining himself sucking hard while letting Naruto shove in and out of his mouth, "Aaaa..." Sasuke stroked himself faster.

He sat up, glazing his fingers in the oil before flipping over, his ass in the air, the towel directly below his cock, his head pushed into the pillow. Naruto was patient but Sasuke wasn't . "Please I need you inside me now." He could hear Naruto give a husky laugh. "You are so greedy, little slut. " Naruto, however, would cave as he always did. Sasuke traced the familiar circle around his entrance and slide a finger into it. He quickly replaced it with two, then added a third. He pushed up onto his shoulder slightly and shoved in a bit more to hit 'that; spot. To him is twas Naruto's thick cock shoving in and out. "Nnggg..." Fuck he wanted it, he wanted, "Naruto." His panting voice was barely heard by his own ears. He kept the pace up as his stomach coiled his other hand reached his cock and out splurt a constant stream of white liquid.

-n-n-n-n-n-

Naruto tossed his keys on his nightstand. He was happy to have made it home in the snow, but also needed to go out. Grading tests while having a boner was hard. He pulled his phone out of his back pocket and sat on his bed. He pulled up his messenger and found the last conversation he had with Ino.

'club tomorrow?'

'I''pick you up at 9?'

'I'll pick you up.I don't want to be seen in your minivan.'

'Fine. This time you leave the dark haired boys for me. Not fair that you suddenly started targeting them,'

'No promises.'

He lay down on his bed and popped open the button on his pants and pulled the tab down. He reached into his pants and grabbed out his cock. There was really only one dark haired guy who he wanted, the rest were bandaids trying to cover up a flooding damn. Sasuke was right in front of him, and he let him go, even pushed him away. "I am an complete idiot." He stroked his cock more remembering the lips on his neck. Yeah, there was zero percent chance Sasuke wouldn't be able to get what he wanted. For now Naruto imagined giving in, and it felt so good, but so unsatisfying. What he needed was the real thing. Sasuke.
