Part 3: The Onset of the Unhinged (Part 2 of 4)

The kisses became a part of their lives as oxygen was to their lungs.

They were staggered throughout the week and only occurred when Sasuke came to Itachi and asked for them. This exchange came with a mutual bond of trust: Sasuke trusting Itachi to give him what he wanted, and Itachi trusting Sasuke to ask for what he wanted. After all, if the boy never gave permission, then Itachi would do his best to keep his paws off.

Their days remained the same save for this little fact, an action that began occurring more often than not to the degree that it became normal.

Emotions had swerved and spun out of control inside Itachi the first time Sasuke pressed his lips to his, and the mere thought of it being torn away from him from that very moment onward was unfathomable. So he was patient when he interacted with his Otouto, and he was loving.

Nothing different from his previous self.

Except for the dark shadow of the ravenous monster being held together inside his chest cavity by layers of epidermis and sheer willpower. It waited behind the bars with its claws gnashing, tail swinging, and eyes glowing bright with uncontained exhilaration. It wailed and it shrieked for comfort, pleas falling onto hungry ears.

Along with his newfound addiction, Itachi no longer sought the company of others. His once-a-week escapades disappeared completely without warning as soon as he realized they didn't give him the release he yearned for. They were empty exchanges, hollow substitutes for emotions that Itachi needed to feel. But no one gave him that emotional and mental high but Sasuke.

A man of logic, quite surprisingly despite his caveman ways, he ditched those nobodies in favor of Sasuke's kisses. The comparison between what he received between the two was so astronomical that it was hysterical. He had had a good laugh the other day in the shower about the irony of kisses feeling better than fucking (albeit fucking strangers).

Another glaring fact became evident when he abandoned his late night activities: the men who were his type were all young, dark-haired, lean built, and pale-skinned. They basically all screamed Sasuke in a large, neon green font.

When Itachi realized this, he didn't feel a sense of shame or guilt. Only pure, unadulterated amusement.

No wonder he always felt like the men he slept with lacked something.

How droll was his subconscious mind really?

Honestly, he didn't know if he should have been surprised with his little discovery. In fact, if anything, he chided himself for being a bit slow on the uptake.

With a sigh, he shut down his laptop and stood, stretching out his muscles as he padded down the stairs. Itachi flicked on the living room lights and turned on the TV, noting that it was almost nine in the evening and his Otouto had yet to come back.

This was another thing he'd been catching himself doing lately: counting down the minutes of Sasuke's return as if he was assigned the role of a dormitory leader. The anticipation for his Otouto's return wrecked his being from the moment the boy left in the morning; it hung heavily in the air like an unaired motel room, the stench causing one's distaste to fester and multiply.

His finger on the remote began tapping out of pure impatience while he checked his phone for any texts or miscalls. Itachi's eyes narrowed when there weren't any, and he set his phone face up on the coffee table.

He half-heartedly found a show on TV that looked mildly appealing and tossed the remote on the coffee table. Nine o'clock rolled around, and Itachi checked his phone again. Nothing. Not even a peep.

Had it always been this agonizing waiting for his Otouto to return? Sasuke's class ended over two hours ago. If he was going to be late, he could have told Itachi.

He'd never felt so anxious before in his fucking life. The more anxious he felt, the more irritated he became. Neither of those feelings made him feel good, and he had no coping skills for such pesky emotions when he'd never had to deal with them before. His it-is-what-it-is and I-do-what-I-want attitudes were inapplicable to this situation because, like he said, Sasuke was the exception to his rule.

And just maybe, just maybe, in that moment, Itachi felt a bit vulnerable, and he despised it. Was this what it felt like to care for another person? If it made him feel so shitty, he should just abandon it like he did with all things that he didn't care for.

However, that's where the tricky part laid. To abandon such a thing would be tantamount to abandoning Sasuke, his Otouto who gave him candy kisses and made him feel inside. Itachi would rather shoot himself in the foot than give that up.

He waited another fifteen minutes, the length of his patience, before he shoved off the couch, ready to grab his phone and keys and go to campus himself to pick up the boy.

And that's when he heard the jingle of keys and the lock turn with a click.

Itachi paused, gaze zoned in on the front door as it opened, revealing his Otouto in his oversized navy blue sweatshirt and dark jeans. A pair of thick-rimmed glasses framed his face, and his cheeks were red from the cold.

Sasuke must have spotted him first thing because he had paused briefly before shutting the door.

"Hey, Aniki," he chirped carefreely as if he hadn't intentionally made Itachi worry sick about his tardiness for the last forty-five minutes. The boy dropped his backpack next to the door and toed off his shoes before approaching Itachi in the living room.

Itachi was rendered speechless between his previous irritation and the boy in front of him, who was now smiling and greeting him. He had half the mind to blast the boy with the questions that had been bombarding him when he sat on the sofa previously.

Where were you? Who were you with? Why didn't you call me to tell me you were going to be late? Did you kiss anyone today? Did you break your promise?

He so badly wanted to ask these questions, but at the very last minute, he bit the inside of his cheek and pushed them aside.

Instead, he reached out to tuck a strand of the boy's hair behind his ear, and he bent down from his towering height to whisper in Sasuke's ear, "You should call me if you're going to be late."

Then, just like that, he pulled back, eyes immediately pinning down Sasuke's features to analyze his reaction. He had hoped his tone didn't come across as threatening; he had tried to lighten it a bit when he spoke, but his intentions and reality could have been different.

The boy pursed his lips and blew out a breath, causing that lock of hair Itachi had tucked away to whisk back into the air and land on his cheek.

"Were you waiting for me?" Sasuke asked cheekily in return.

To Itachi, it looked like he had inhaled one too many fumes because, instead of feeling sorry for making Itachi worry sick, Sasuke was teasing him.

No matter. It was the nature of their relationship anyway. Itachi almost wanted to sigh and forfeit.

"Yes," he answered seriously. His response seemed to have startled Sasuke.

"Oh. Sorry. I'll let you know from now on if I'm going to be late."

This answer should have appeased Itachi, but he found himself loathing it. It insinuated that there would be future instances when the boy would return after hours. What reason did Sasuke have to stay out late anyways? They had everything they needed at home.

He nodded his head and flicked the boy's forehead. "You look hot with glasses, Otouto."

The boy grumbled and flinched. "Shut up," he said, rubbing the spot between his eyes.

Then, without warning, Sasuke's fingers gripped onto Itachi's collar and pulled him down while he simultaneously pressed himself up on his toes. The man's eyes widened briefly when he felt a wet one placed on his lips, and any other concerning thought vanished from his mind.

Well, this was a surprise, he thought as their lips molded together. This was the first instance Sasuke didn't ask for permission before he kissed Itachi, and it was downright intoxicating.

Itachi was enraptured.

His Otouto had a set of big balls on him to do such a thing to him without his permission, but he didn't complain because Itachi loved it. He folded his arms around Sasuke's waist and picked the boy up only to settle them both on the couch with Sasuke in his lap.

"Good boy," he growled, hot and heavy against Sasuke's parted lips, as his Otouto flattened his tongue along Itachi's lower lip, begging for entry.

He noted Sasuke's brief pause followed by the small, tapered moan caused by his words. Sasuke remained slack-jawed against him for a mere few seconds.

Oh?

Did Sasuke like it when Itachi called him a good boy?

Sasuke finally snapped out of it and slid his tongue past Itachi's lips, just like the elder had shown him nights before. Itachi was patient, following Sasuke's whims as the boy toyed with his tongue and moaned quietly at his taste. He must acknowledge that the boy had gotten more enthusiastic in his actions as soon as those two words fell from his lips.

Hmm, Itachi must test it out. He must get to the bottom of this immediately.

He pulled back gently from the kiss with a peck to the boy's lips, but only far enough to open his eyes to see his Otouto. Sasuke stared back at him in a daze, chest rising and falling rapidly. His arms had ended up around Itachi's neck from their seated position and he had yet to snap out of his pleasure-induced haze.

"Did that feel good, Otouto?" Itachi whispered, licking his lips. They tasted like Sasuke, so sweet and tantalizing. The term of endearment fell easily from his lips, a word that burned Itachi's ears at how incredibly hot it was.

Itachi was going to Hell, but he'd gladly descend with a smile.

"So good," Sasuke's voice hitched. His hands had refused to let Itachi go.

"Can you be a good boy for Aniki and let Aniki –"

Suck your cock. Play with your nipples. Eat your asshole. Press you down on my cock. Cum so deep inside you that you'll get pregnant.

Ah ah ah, that was dirty Itachi. He needed to reign it in a bit. The man swallowed hard. This was Sasuke, not a one night stand.

"–touch you here?" he finished, fingers creeping underneath the boy's large sweatshirt to caress Sasuke's naked skin.

As soon as those two words were uttered, Sasuke swallowed hard and his entire body shuddered in Itachi's lap.

Unbelievable. Itachi thought he may have been overthinking it, but here was the confirmation in the form of a moaning, quivering boy in his lap.

The things that he could do with this newfound information. He'd have to store that away for safekeeping.

Itachi's hands laid still along the boy's obliques except for the minor caresses of the skin he found there. It felt too soft, too pretty not to touch. But the rest of him waited for permission like a loyal servant.

Sasuke looked unsure, yet curious. Interested, yet bewildered.

"Just t-touching?" he asked. Itachi nodded with a small smile and echoed his words. "Can I…" the boy bit his reddened lips, "still kiss you at the same time?"

Was Itachi dreaming?

This was too good to be true. He thought sinners were supposed to reap their karma, not rewards, but he surely wasn't complaining.

"Of course you can, Otouto."

"Okay," the boy whispered, and the chains wrapped loosely around the cage hidden inside Itachi jingled with delight.

Itachi's unhurried fingers stroked along Sasuke's sides as he received his second kiss of the evening from his Otouto. The sweet boy had the audacity to gasp and jerk his hips against Itachi's when Itachi bit down gently on his lower lip and tugged affectionately while he simultaneously brushed his fingertips along the peaks of Sasuke's nipples.

He must have felt Itachi's erection straining against his loose fitting sweats. There was no way he couldn't have. Quite frankly, there was nothing underneath them, and he could feel his hard cock threatening to peep out from underneath the waistband of his pants and make its grand entrance. If it did, it wouldn't just be the head. Itachi was much larger and longer than average.

Not that that predicament would leave him embarrassed, but he couldn't say the same for Sasuke.

Itachi tugged on Sasuke's lip again in another small bite, sucking the boy's pouting lower lip between his own for a small suck. His fingers pinched the nipples he had found, rolling and pulling them gently. The boy moaned and thrashed against his body.

"A-Aniki" came Sasuke's sweet, hesitant call, as if he was asking Itachi to stop.

But Itachi didn't want to stop. Far from. But he did, pulling away from his Otouto's lips while his hands returned to their original position against the boy's hips.

"What is it, baby?" he asked, his sex-induced voice accidentally allowing the term of endearment to slip by. It was coupled with a gruff tone that Itachi didn't hear until after it was uttered. Fuck.

Sasuke's chin drooped, as if he was unable to meet Itachi's gaze in fear of disappointing him.

This was it, Itachi thought. Sasuke was calling it. He was going to end things here, never to be revisited again.

"Tell me," Itachi uttered. His hands on Sasuke's hips clenched down, as if relaying the message that he wouldn't be able to run even if he wanted to. He refused to let go unless he heard the boy tell him to stop and get the fuck away from him.

"C-Can I also touch you?" Sasuke asked.

To say Itachi was floored would be an understatement. His mouth went dry and he had to clear his throat in order to speak.

"Where do you want to touch me, Otouto?" he asked as he released his hold and withdrew his hands from underneath the boy's sweatshirt. Instead, he unwinded Sasuke's hands from his neck and held them in his own.

Sasuke gulped at his question, causing Itachi's mind to go haywire.

"Do you want to touch me here?" Itachi asked, bringing one of Sasuke's palms up to cup his cheek.

The boy glanced up at him, almost shyly, and shook his head.

"How about here?" Itachi repeated, pressing the boy's palms flat against his torso. His pectorals flexed underneath the touch.

"Not there," Sasuke whispered.

Hmm, there weren't that many places left.

"Do you want to play with my cock, Otouto?" Itachi murmured, a hint of seductiveness weaseling into his tone.

Sasuke's face burned bright red and his gaze flickered to the twitching erection hidden beneath the flimsy cloth of Itachi's sweatpants. But he didn't say no.

"If you don't tell me, I won't understand," Itachi said, gaze tender and words coaxing.

That was pure bullshit.

He understood perfectly fine, but he wanted to hear the boy say it from his pretty, pouty mouth.

"Do you need me to tell you what to say?" Itachi asked, as he leaned forward slightly to press a kiss to Sasuke's cheek.

The boy nodded fervently.

"Say, 'Aniki, I want to play with your cock'. You can say that, can't you, Sasuke?" Itachi's eyelids lowered partially. He was getting drunk off this interaction, and it became hard to control his words and movements.

He heard the gulp before the words.

"A-Aniki," Sasuke whined, "I-I want to… play with your cock."

Itachi purred at those words, guiding one of Sasuke's palms underneath the waistband of his sweats, effectively popping out his swollen erection, before pressing both their palms against it. Itachi shifted his hips slightly, tugging his sweats over his bum to rest bunched up around his thighs.

"There you go, my sweet Otouto." Itachi could barely control the groan of approval and pleasure from feeling Sasuke's hesitant hand cup his length. Very slowly, he withdrew his own hand and allowed the boy free reign.

"We shouldn't be doing this," Sasuke whispered, large astonished eyes rooted on Itachi's very lively erection.

It had swelled so much that it had turned a newfound shade of crimson. The blushing head was wide and dome-shaped, silky soft to the touch and ever so energetic. Itachi couldn't remember the last time it had looked so needy, weeping droplets of precum like a leaky faucet.

"Why not?" Itachi countered, half-hooded eyes staring openly at Sasuke's blushing cheeks. He was mentally getting off simply from having Sasuke's hand cupping him. "Give me one good reason why not," he said.

"Because… we're brothers."

Oh… yeah. Inwardly, Itachi nodded. Well, there certainly was that little detail.

It was common knowledge not to fondle your own Aniki. Of course Sasuke would know this.

No matter. Itachi waved it off.

"But aren't you curious how it would feel?" the man asked, the steaming lust in his tone beaten down by the softness in his voice.

Itachi bit his lip. He almost lost it and laughed aloud. As if curiosity was somehow equivalent to the fact that they were pure, blood-related siblings from the same womb.

The answer to his question was evident on the boy's face. Even his hand, although frozen against Itachi's smoldering cock, had not pulled away. That was a good sign.

Itachi gazed fondly at Sasuke as the boy's brows furrowed as if he was battling an internal war. With just an itty bitty nudge, Itachi gently rocked his hips against his Otouto's palm, grinding his erection against it. The man bit back a growl when he did it again and again and again until a rhythmic motion began.

His Otouto gasped, poor thing, as if it was his first time palming an erection, and to be honest, it probably was given that he was a virgin who abhorred people. Itachi could not see Sasuke allowing anyone to touch his body nor vice versa.

Finally, as if the boy was too entranced to deny his wanton ways, Itachi felt delicate fingers wrap around the base of his thick cock, the erection, itself, too wide in girth to allow the boy to fully wrap his delicate fingers all the way around. He moved his hand up once and then again, and Itachi felt as though he had revisited his youthful days as a virgin. How embarrassing.

He tried to keep his groans to a minimum and bit his lip to shut his trap from spouting its usual sex-induced jargon. He'd save it for another time when Sasuke was more accustomed to him.

"It's big and hot," the boy whispered, leaning forward in Itachi's lap to get a better look. Itachi's cock twitched again in Sasuke's hold, and the head of his erection glossed over with copious amounts of precum. "Aniki, you're dripping."

Did his Otouto want him to fuck his mouth? He most definitely stated it as an observational fact, not in a 'come hither' tone. Either way, if he didn't want to end up with a sore throat, he should probably stop talking.

"Do you know why it's dripping so much?" Itachi asked, leaning his head back against the sofa. He let Sasuke play with him as promised and watched from the sidelines.

Sasuke moved his hand over the head and pressed a finger down against the leaking tip, eliciting a hiss from Itachi, before he got more comfortable in his movements and began spreading down the precum in his strokes. Itachi got an inkling the boy was attempting to replicate what he usually did himself late at night in bed.

He had yet to answer Itachi, and the man did not know if he would respond as he delved deeper into his movements as if mesmerized with Itachi's cock in his hand.

All of a sudden, the boy removed his hand from Itachi entirely, and the elder thought that was the end of that, except when he trailed his gaze after Sasuke's retracting hand, he noticed it was moving toward his mouth. That was when Itachi's pounding heart might as well have given up on him because it stuttered in disbelief as those slender digits met an awaiting tongue.

One lick.

Schluck.

As if he was licking honey off his fingers.

Cheeks still red and body still seated in Itachi's lap, Sasuke had tasted his precum.

That was a bold move. Very bold indeed.

When did his Sasuke get so bold? Or was he always this bold and Itachi just didn't know it?

Why was he eating his precum in front of Itachi as if he hungered to try it out, to taste the body fluids that his Aniki produced? Now a part of him was inside of his Otouto forever.

Why did he have to go and do that? Was he having fun torturing Itachi so?

"If you're having doubts, we can stop, and forget this all ever happened," Itachi found himself saying. He needed to put a halt to things before they went beyond his control.

Okay, no. That was a lie. Itachi needed to put a halt to things before he got out of control.

Sasuke paused mid-second-lick before his tongue coiled around the fingers that had just grazed passed Itachi's leaky slit and shoved two fingers in his mouth to collect the remnants.

"No" came Sasuke's adamant voice when his fingers withdrew. "I don't want to stop."

Good God, he was going to get blue balls soon if the boy kept spouting these lines at him. Where did he learn how to speak like that?

"Say that again," Itachi growled. He held the boy in place by his hips and thrust his hips forward to meet Sasuke's. "Tell me again."

He was giving Sasuke an out. A free pass to stop the madness before he, too, got roped into it. Itachi wasn't known for his gentle, kind nature in bed. In fact, he ranked on the opposite end of that spectrum.

It was always dirty, unrelenting, hardcore fucking. Itachi had a really bad mouth on him, and he was unable to curb it for the life of him. He took as much as he wanted in the bedroom and left no shred of dignity left for his partners. They all ended up a sobbing, cum-soaked mess, but they'd purr in complete and utter satisfaction.

Sasuke would need to take a day off school tomorrow, and he'd have trouble completing normal daily tasks. Did he understand that?

Well, then again, this was Sasuke he was talking about, his special, special, boy, so maybe he'd go easy on his Otouto.

"I don't want to stop, Aniki," Sasuke said. "You taste good."

Fucking hell.

Itachi had given Sasuke an out. He had given the boy the opportunity to clear the slate, but Sasuke rejected it.

Sasuke would never have another opportunity to reject Itachi again.

That was the boy's answer, and he was locked in for life.

H.J.

Oh. My. Jashin. What did I just write?
