Part 1

There were plenty of dangerous things in the world, and rarely could you bypass their scrutiny by epitomizing the core of an idiot. And that was what Itachi's Otouto was currently. An idiot.

The rectangular tic tac looking container, which sat innocently atop Sasuke's nightstand, was proof of such idiocy. Upon closer examination, it was also full. Not a single pill removed for consumption. So why, if the purpose of receiving prescription medication was to take it, did his Otouto ditch it so irresponsibly?

Had Itachi not stepped into the boy's room to close his window that morning, the idea of danger could have taken a step closer to deadly in a matter of seconds. Itachi snatched the container and held it tightly in the palm of his hand, revved up his engine, and instead of making the usual right turn down the block toward his university, he turned left and headed for Konoha High School.

In a world overrun by raw instinct, power, greed, and lust, he'd be damned if he didn't keep a close watch on his brother.

H.J.

"Uchiha Sasuke, please report to the nurse's office. Once again, Uchiha Sasuke, please report to the nurse's office. Thank you."

The intercom message blared through the classroom loud and clear, and hardly needed to be repeated. Sasuke, who had been staring out the window from his seat at the back of the room, languidly stood up with a grumble and stuck his hands into the pockets of his uniform.

He strolled past the sea of giggling girls, envious whispers, and Kakashi-sensei's dull lecture on dominant and recessive genes and made his way down the hall. Sasuke made sure he took his time getting there to silently protest being called out for no reason. Even if it took the typical individual two and a half minutes to arrive at the destination, he managed to arrive six minutes after he stepped foot out of his classroom. A new personal record.

He hadn't even reached up to knock on the door when it swung open, the hinges rattling at the sheer force, and Sasuke was hit with a very familiar scent of a very angry man.

As always, there was only ever one reason he had ever been called to the nurse's office, and that one reason was tied to why his brother bothered showing up at his school mid-morning.

He peeked over Itachi's shoulder and noted that Iruka sensei, the school nurse, was not present. Probably due to the overwhelming amount of pheromones the man was emitting. It would have easily suffocated the average person. Itachi seemed to note this detail as he grabbed Sasuke by the wrist, dragged him in the room, and locked the door behind him.

"Aniki, you're stinking the room up," Sasuke said, shaking out of Itachi's grip. He ducked under the man's arms, which had been caging him against the door, and sat down on the infirmary bed. "You know your pheromones don't affect me, right? I've grown up next to you my entire life."

There was a large window facing the courtyard from the room, and Sasuke idly glanced out. It was a cloudy day with no ray of sunshine in sight. He wished he was outside right now. The wind would feel nice against his face.

The room smelled the same, meaning Itachi's irritation didn't let up. Itachi was staring at him again. Even at home, it was the same as usual. So ordinary and boring that it didn't bother him much.

Sasuke sighed. "Why are you here, Aniki?"

The man stuck his hand into his pocket and pulled out the oh-so-familiar white container and tossed it onto the bed. Sasuke's eyes flickered downward for a split second before he looked over at his approaching brother.

This again, huh?

"Take it, Otouto."

Sasuke palmed his face as a quiet laugh shook his shoulders. Leave it to his brother to deliver a command in such an eerily calm manner. As quick as the humor came, it disappeared in favor of indignation. "Why should I?"

"I wasn't asking, Sasuke." Itachi stood before Sasuke, his tall broad figure easily hovering over his sitting form.

"I don't want to," Sasuke muttered as he swept a hand through his spikes. "Why do I have to? I'm already 17 years old, Nii-san, and I've never shown any signs of going into heat or otherwise. My genes are dormant."

"Are you going to wait till the symptoms surface before you start taking your inhibitors?" Itachi growled. "Don't be ridiculous, Sasuke."

"That's easy for you to say! You were born an alpha, Itachi! How would you know what it's like on the other side of the fence?"

"You're right, Otouto," Itachi responded as he splayed a palm next to Sasuke on the bed and leaned over. "I don't know what it's like being an omega." He leaned in closer until their faces were inches apart and Sasuke could tell how serious he was. With his other hand, Itachi flicked the cap open on the container and dumped a single oblong pill into his hand. "But you know what? I sure as hell am not going to stand by and watch you make poor decisions that will ultimately determine your fate, Otouto."

Sasuke's wide eyed gaze followed his brother's movements as he tried to inch backwards away from the unoccupied hand that reached for him. He felt a hand clasp around his throat and felt his head bounce slightly against the mattress as he was shoved flat against it. His heart lurched in frightful panic against his chest as he glanced between the pill in Itachi's hand and Itachi's burning gaze.

"Aniki, what are you doing?" he nearly cried, but his voice came out in a hoarse whisper.

"I would rather kill you than have you go into heat in front of another alpha, Sasuke."

"W-What?"

"But it won't ever reach that point. I'll make sure of it even if I have to force it down your throat every morning."

"S-shit, Itachi. What are you saying? You're scaring me," Sasuke murmured, blurry eyes staring incredulously up at the man hovering over him.

"Open your mouth, Sasuke," Itachi commanded.

The younger Uchiha's lips parted slightly to ask why Itachi thought he would do such a thing, but as soon as he opened his mouth to speak, the pill disappeared between his brother's lips and then they came crashing down against his own.

He made a sound akin to a 'mmph' as Itachi forced his tongue into his mouth, passing along the pill with bruising force, before he pulled back, used a hand to close Sasuke's jaw, and demanded that he swallow it.

Sasuke did so, tearing the man's hand away from his mouth and throat as he turned sideways and began coughing loudly. The pill torturously made his way down his throat.

"What the fuck, Aniki?" he hollered, thrashing against the body on top of his. His lips tingled oddly and he held back the urge to touch them, and damn it that was his first kiss. That asshole!

Next thing he knew, he was scooped into Itachi's arms, flipped around, and perched onto his brother's lap. In a mere three seconds, the man had sat up and hugged Sasuke to his chest as if he hadn't force fed him mere seconds ago.

He stopped thrashing and placed his hands on Itachi's shoulders to balance himself. He was about to launch a stream of expletives at his brother until he felt the man's hands clasp desperately to his back and felt his Aniki's face dig into his neck.

Itachi was hugging him.

Sasuke's brows wrinkled in confusion. "Hey, you okay?"

The prior pheromones that showcased anger in the room had dissolved quickly after that, and all that was left was Itachi's personal scent, which was emitting from him in waves. Sasuke could easily smell him because he was so close.

"I know you don't want to be an omega, Sasuke," Itachi's muffled voice said. "But I've always been glad you were born an omega. I knew as soon as you were born you were one, and I've never been happier. But when you don't take your medication regularly, I worry about you. So if not for yourself, then for my sake, please take them. I want you to be safe."

Did alphas always have terrible mood swings? One moment, Itachi was talking about killing him and the next he was being sweet. Ugh, he could never understand what his brother was thinking.

Sasuke ran his fingers through his locks and grumbled. "Fine," he said. How could he refuse Itachi when he said those kinds of things? He grabbed the container and stuck it into his pocket.

"Good boy," Itachi praised, pulling away and kissing Sasuke on his forehead. He lifted the boy up and set him down onto his feet.

"Can I go back to class now?" Sasuke asked.

"You may, Otouto," Itachi murmured. "I'll come pick you up after school. We'll go get some sweets for you."

"I swear, Aniki, you still treat me like I'm five," Sasuke muttered, unlocking the door. "I'll see you when school lets out."

"Be good, Sasuke."

"Yeah, yeah."

When Sasuke returned to his class and took his seat, Naruto looked at him from his seat in front oddly.

"You okay? What took you so long?" his blond friend whispered.

"It was nothing. Don't worry about it."

"You smell slightly off. Were you talking to someone at the office?" A flying eraser hit the back of Naruto's head, causing him to lurch in his seat and yell. "Ah, Kakashi sensei! Whyyyy?"

Off? Sasuke thought. He brought his sleeve up to his nose to take a whiff, but he didn't notice anything off about his scent. Maybe Naruto was the one off… off of his rocker, that is.

H.J.

"You're late again, Itachi," Kyuubi murmured, gaze sliding over to the man who occupied the seat next to his. They were seated at the back of the lecture hall that housed over two hundred students, so tardiness wasn't a big deal, but the reason for it especially when it came to the responsible Uchiha was always a means to pry.

Itachi propped his elbow on the individual table and rested his cheek against his palm, nonchalance rolling off of him in waves.

Kyuubi cackled quietly to himself. If Kyuubi could guess, the man probably didn't look like that prior to attending the lecture. His behavior was so blatantly cyclical that it wasn't too difficult to read him.

"Chibi's not taking his meds again, eh?" he said. It was more of a statement really.

The huge sigh he heard in response tickled Kyuubi's senses even more and the corner of his lips quirked. The man was pouting. How cute.

"What are you going to do? It's not like you can be around 24/7 to play doctor."

"Maybe I should just lock him up," Itachi mused.

"I think there are laws that protect omegas against that," Kyuubi said. "Well, there are laws that protect all humans against that."

How tedious. But Itachi supposed it was necessary to be governed by rules that protected people like his Otouto. In a society where ninety percent of individuals were human, the remaining ten percent either identified as alpha, beta, or omega.

Betas were plentiful and hardly considered a rare breed compared to omegas and alphas. Alphas made up approximately two percent of the population of lycans whereas omegas were half of that. Alphas were born and bred of their kin as were omegas. Two betas couldn't simply give birth to an alpha or an omega at will. There were genes in play.

And Sasuke belonged to that one percentile. He was so rare a breed that the Uchiha clan thought it would be best to pass him off as an alpha to prevent lingering, unwanted attention. It wasn't unbelievable that Sasuke could pose as an alpha coming from an alpha father and omega mother. Besides, if the wrong individuals caught wind of an unmarked, defenseless omega, then the boy would be in trouble in a flash.

That was the other thing about omegas: whether they were male or female, an omega who had had their first heat was incredibly fertile.

The mere thought of Sasuke giving birth to another alpha's baby caused a growl to erupt at the base of his throat. There was no chance in hell that was going to happen. Not only did Itachi forbid it, but his Otouto had yet to have his first heat. In lycan terms, he was still a baby.

His genes had been laying dormant for years. Usually, puberty came between the ages of eleven and thirteen. Whereas Itachi had his first rut when he was twelve, Sasuke was currently seventeen and experienced no such thing. In human terms, he hadn't even reached puberty yet.

The bi-monthly checkups with Shisui at Konoha General never revealed anything threatening or different. He was just a late bloomer.

Whatever the reasoning, his Otouto's current behavior could lead to very devastating results. Itachi sighed once more, flicking his bangs away from his eyes and ignoring Kyuubi who seemed to be reading his thoughts quite joyously.

At the very least, it was helpful that Itachi knew that, when he was sweet toward the boy, he had a higher rate of success when it came to that unabashed, stubborn attitude of his. If that didn't work, he could continue to force those pills down Sasuke's throat.

If only his Otouto knew why Itachi had to do all of those things.
