Chapter Two

Somebody take the pain away
It's like an ulcer bleeding in my brain
So send me to the pharmacy
So I can lose my memory

Itachi and Sasuke retreated to the forest after breakfast, Itachi never speaking to their parents. Fortunately, Sasuke didn't notice. It was a miracle he never noticed how distant Itachi was to his parents, how they never talked, or even made any contact whatsoever. It was better that Sasuke didn't understand the hidden tension in the house between the rest of his family. The one thing they all had in common was Sasuke's happiness.

Itachi and Sasuke traveled through the trees to the lake, Itachi in the lead, warning Sasuke of upcoming ditches and branches. They memorized the path, so it didn't take long to reach the lake. It was clear and still, like a sheen of glass instead of a pool of water.

"Ohh, nii-san, it's so pretty!" Sasuke marveled, kicking off his shoes so he could dip his foot in the soothingly warm water. A few small fish tickled his toes and he giggled, swirling rivulets in the lake, mixing the shadows of the trees that decorated the surface.

He pulled off his shirt and set it in the sun so it would be warm when they returned home. Itachi stared, though inconspicuously, as Sasuke undressed to his boxers, which, he noted with amusement, were his.

"Come on, 'Tachi!" Sasuke called, waist deep in the water. Itachi followed eagerly, gliding extra close to Sasuke so their legs were touching. Itachi brushed even closer, holding his breath at how smooth and soft Sasuke's skin was. Sasuke laughed, playfully pushing Itachi away. Itachi growled at him teasingly, and Sasuke spun around and swam from his older brother, who waded after him.

A simple game of chase soon turned into something much worse.

Itachi caught his Aniki very quickly, jumping on him as they rolled together under the water. Limbs tangled with limbs, flesh pressed against flesh. Once they resurfaced, Sasuke was panting, trying to catch his breath. He glared at Itachi.

"Don't do that!" He scolded breathily, still choking a bit. "You almost drowned me!"

"Sorry, otouto," Itachi apologized, but he knew Sasuke wasn't really that angry at him.

"Hmm…" Sasuke looked away, but Itachi could see he was grinning. "Okay!" Itachi draped his arms around Sasuke's bare shoulders, and Sasuke leaned backwards into the embrace.

"Mm…Sasuke…" Itachi muttered, snuggling his head into Sasuke's neck. Sasuke smiled even wider, taking Itachi's hand in his. They did this often; just cuddled. But Itachi felt a stone sink in the pit of his stomach, telling him this was going to go a lot farther than ever before.

But Itachi made no move to stop.

"Sasuke…" Sasuke shivered as Itachi groaned his name, for reasons he didn't understand. "Will you…will you turn around for me?

Sasuke complied, turning so they were face to face. He automatically wrapped his legs around Itachi's waist, not seeing the lust filled expression that flickered across his eyes at that motion.

Itachi sweetly kissed Sasuke's nose, then nuzzled his own nose against it. Sasuke closed his eyes and melted, just glad that his brother was paying attention to him in this way. It didn't cross his mind that it might be wrong, because he had never been shown what "sex" was. His parents protected him from it, since he had such a strong relationship with Itachi. All he felt at that moment was pleasure and contentment; true bliss.

Itachi then ghosted his lips over Sasuke's, not quite touching. A moan escaped without Sasuke's control, begging to be kissed. He had never been kissed like that before, and who better than to share it with than his brother, who knew him better than anyone? They had been so happy so far, but what could make it even better then if they kissed? Kissing meant you loved someone, right? That you wanted nothing more than to be with them? That's exactly what Sasuke wanted.

But in a different way that Itachi did.

But Itachi denied him, instead leaning down to kiss Sasuke's pale, slender neck. He bit down slightly, causing Sasuke to squeak in surprise, but quickly got used to it and let Itachi go on with his ministrations. Sasuke watched his every movement, whimpering as his neck and shoulders were covered with red and purple marks. It felt so good! Why hadn't they done this before?

"M-mo---" Sasuke tried to say, but his voice caught in his throat as Itachi lifted Sasuke out of the water and pushed him against the rocks surrounding the lake, his body almost completely revealed. Itachi gripped Sasuke's arms and licked at his small but pert nipples, and a cry erupted from Sasuke's parted lips.

"What was that?" Itachi said, his teeth closed around the bud. "Say it so I can hear, Sasuke."

"M…m-more…" Sasuke gasped, feeling more attached to Itachi than he ever had. Whatever Itachi was doing to him, it felt amazing, and he wasn't afraid to ask for more.

"As you wish…Sasuke." Itachi used one of his hands to pinch Sasuke's nipple, still energetically sucking the other one. He knew what he was doing was extremely wrong and dangerous; he could give Sasuke the wrong idea, he could make Sasuke grow distant from him because he was afraid of his older brother's advances.

But most of all, Itachi was worried that he wouldn't be able to stop before it got too intense. The sweet, delicious noises Sasuke was making was like music to his ears, the obvious husk of love and unacknowledged lust in Sasuke's voice digging into Itachi's heart, as well as, more even, his slowly ebbing self control. He had managed to restrain himself for so long, but strangely, it felt like all of him had just been drained. He couldn't hold on anymore. Sasuke was teasing him without even knowing he was doing it, and it was horribly mouth-watering. Somewhere, in the back of his mind, he was sure something terrible was going to happen, he was sure he wouldn't even think about stopping his touches on his beautiful brother.

And he tried not to care.

Sasuke yanked Itachi's wet hair, gripping it in an attempt to quiet his shrieks of delight.

His mouth gaped and his eyes widened as a new sensation rushed through him; his boxers tightened at the crotch and he suddenly felt hot, like he had just been fiercely burned all over his body. It was so pleasant, he didn't want it to end. He was immensely happy that Itachi was making him feel this way, giving him such enjoyment. It was more than he could have ever asked for.

"I-Itachi!" He screamed, arching his back, his chest touching Itachi's. The pleasure racked through him like a storm, making him tremble and shake with the very force of it. It was almost too much for him. "Itachi, i-it feels good! W-what…?"

"Shh, otouto…" Itachi whispered calmly, planting soft kisses over Sasuke's chest and stomach. "It's okay, it's natural to feel good. Don't worry." Sasuke nodded and took a deep breath, relaxing for his brother to take control. Even though Itachi was mentally deteriorating, he put on a mask of certainty and calmness, like he knew exactly what he was doing and how it was going to plan out, when really, he was bubbling with desire, worry, and sadness all the same time. It looked like he would just have to keep going and see what happened. Because he was absolutely positive it was too late to stop now.

Itachi bit gently around Sasuke's abdomen, then dipped his tongue into his navel. Sasuke gasped and screwed his eyes shut, breathing heavily as more unknown feelings shot through him. The tightness down below was unbearable, but it didn't know if he wanted it to stay or be released. It was so severe, he felt like he was going to explode any minute. But on the other hand, it was too fantastic for him to want it to end.

It was confusing, making his vision misty and his mind whirl. His stomach was in knots, but it wasn't the sort of pain he felt when he was sick, per say. It was more of a tightness, really, a rope being tied into unbreakable loops until it would simply rip into pieces. Would that bring him relief? Or disappointment?

"Whaa--? Itachi!!!" Sasuke screeched high and loud, tears pricking at the corners of his eyes as Itachi roughly palmed his dick. It felt hard, pressing against his boxers as if it was trying to escape. Water splashed around them as Sasuke writhed at the unfamiliar feeling; he had never been touched there, not even by himself. He didn't masturbate, as he had no idea what it was. Whether his ignorance was bad or good, nobody could tell.

"Sasuke, try not to scream so loud," Itachi said nonchalantly, though he just wished he could keep going, faster and harder, but Sasuke was too fragile at this moment. He would take it slow, at Sasuke's pace, until he got what he wanted. But it was so wonderful to be touching his obsession like this, and getting such a fantastic reaction was even better. His fingertips tingled every time he slid them down Sasuke's flushed skin. "Someone will hear."

"S-sorry, nii-san…" Sasuke blushed furiously and lowered his head, but Itachi titled his chin up so they could gaze at each other.

"It's okay," Itachi assured him, his voice low and sultry with affection. "It feels good, neh?"

"Y-yeah…" Sasuke breathed. Itachi hesitated for the shortest second before putting his hand back on Sasuke's member.

"This is your first time getting an erection…" Itachi said, more to himself than to Sasuke. He was so turned on by Sasuke's own arousal, that he was the one to cause Sasuke's first hard-on.

Sasuke didn't answer as Itachi began rubbing him again, all the while nibbling on his ear. Sasuke emitted such delicious noises, it was almost too much to bear.

"W-wait…Itachi…s-something…it feels like s-something's gonna…c-come out!" Itachi smirked, knowing his little brother was getting close to climaxing. He couldn't wait to see Sasuke's cock throbbing as it exploded in hot, milky cum, splattering over Itachi's face, screaming his name.

But it never happened.

They were interrupted by an outraged roar coming from the back of their house, and Itachi snapped his head around to see his parents in the window, getting a clear view of what they had been doing.

Shit.

It resembled a death sentence.

Mikoto and Fugaku paced the room relentlessly, their hands clasped behind their backs, their eyes lowered darkly and menacingly. They had dragged Itachi and Sasuke home, and planted them in the living room, side by side.

A death sentence.

They had even gotten dressed, and they were still wet from the lake and Sasuke was still sporting a rather impressive erection, that was very easily noticed. Itachi remained emotionless and rigid, keeping his eyes forward and his posture straight. As their parents paced, Sasuke's face was in his hands, and he was trying to quiet his sobs. He didn't understand what was going on, or why his parents were so furious. What was worse was that Itachi wasn't doing anything at all.

Itachi scowled invisibly to himself, watching Mikoto and Fugaku think of something to say to their disgraceful son. He had been caught. The terrible thing was this, the thing he had predicted. He had hoped it wouldn't be this bad, but he supposed he couldn't expect anything less.

But he would take it. He would take any punishment his parents would give him, as long as they didn't do anything to Sasuke. He knew this was coming, they had suspected something from the very beginning.

And they were finally responding to it. Itachi had always known he disliked his parents, since they didn't approve of him and Sasuke. If they got in the way, well, then, that would be a problem.

"Itachi…" Mikoto was the first to speak, and it was softly, coolly, her bird-like voice hardly raised even the slightest bit. This was like her; she never yelled, or got upset, or anything that required "stress." So seeing her with her face taut and her body tense was unpleasantly rare. "You know why we're upset with you."

"Yes," Itachi replied composedly, clenching and unclenching his fists. "I know."

"Itachi…I don't quite understand what you're trying to do here. Sasuke is…your brother."

"I'm aware of that."

"Yes, you're aware of it!!" Fugaku shouted, throwing his arms up in exasperation. Sasuke flinched backwards at the outburst, and Itachi unashamedly put his hand on Sasuke's lower back to comfort him. This made Fugaku angrier, and Itachi smirked. "Itachi, this is wrong and immoral and disgusting and I--I can't believe y-you would---" Fugaku trailed off in outrage, turning his back again to let Mikoto take over.

Sasuke was silently sniffling into his wrist as Mikoto took a deep breath.

"Sasuke, please go to your room," she said. "We need to talk to Itachi alone." Sasuke paused, unsure if he should listen. Itachi leaned down and whispered into Sasuke's ear,

"Go. I'll be there in a second." Sasuke flicked his wide, teary eyes from his fuming parents to Itachi, then nodded, and shuffled away up the stairs.

Itachi turned back, his face still uncaring, his arms folded.

"Well?"

"Itachi, you're going to hurt him," Mikoto said, wringing her hands together. "You're going to scare him. Do you want that? Do you honestly want him to drift away from you because of something like this?"

"He likes it."

"You want to believe he likes it," Mikoto sighed, obviously trying to control her temper, while Fugaku had lost his long ago, and was now pacing and grumbling to himself. "He's your brother, Itachi, you can't do this sort of thing with him."

"Why not?"

"We forbid it."

"I'm almost an adult. I don't have to listen to you."

"As long as you live under our roof, you live under our rules."

"What if I don't live under your roof?"

"Itachi, please don't do this!" Mikoto begged; she didn't have enough fight in her to argue with Itachi.

Itachi knew it was just eating them up inside. As the oldest son, they had big things planned for him, they wanted him to get a nice, well-paying job and marry a beautiful, smart, successful, decent woman and have lots of children. Very high expectations. When they saw that Itachi had no intention of following their blueprints, they knew they had to do something, or Itachi would be lost to them forever. Itachi knew he wasn't bluffing about running away, and they knew it too. He would leave in a heartbeat, and take Sasuke with him. But that's not what Sasuke wanted.

At least, not yet.

"Don't do what?"

"You don't want this, you need to think this over!"

"I've done plenty of thinking." And so he had. As soon as Sasuke was born, he had lots of time to think. He wouldn't be pressing this so hard if he wasn't completely and absolutely certain about what he wanted.

"You're still so young!" Mikoto tried, willing to make any argument to change Itachi's mind. "Even if you're sure this what you want, you're too young to make a huge decision! Try some other things out, experiment, and you'll see this isn't what you want after all."

"I'm not going to try sleeping around with women, if that's what you're implying," Itachi said robotically. "I think I'm old enough to decide just how gay I am." Fugaku made some sort of angry, spluttering noise and flung open the front door, holding it open and glaring at Itachi.

"Well, if you're so sure, then leave!" He roared.

"Fugaku…" Mikoto warned half-heartedly, but Fugaku ignored her.

"Leave our house, we don't want you here!" Itachi remained calm, not even permitting himself to speak, afraid he would say something awful if he did. He couldn't stay so nonchalant much longer, especially when his parents were being so foolish about the whole thing. They knew they couldn't change him, and yet they persisted on making a scene with him. Was it so bad? Really, was it that terrible? Itachi didn't think so. Maybe it would be better if he just left, making sure to come back and get Sasuke if he did…they could leave, and be happy together, and forget about their controlling parents for good.

"Fugaku, please…"

"Mikoto, I'm not going to be lenient with him any longer!" Fugaku was so mad, he was visibly shaking, and Itachi involuntarily took a step forward. "T-this…this faggot won't be living in our house anymore!"

Itachi lunged, flying past Mikoto and barreling into his father, tackling him to the ground with fury. They had never gone that far before, and now, Itachi was going to retaliate. He wasn't going to be denied his craving, no matter what he had to do.

Mikoto screamed as Itachi easily pinned Fugaku to the ground, flitting around them and shrieking at them to stop. But Itachi was deaf to her pleading and he mercilessly punched at his father, his eyes black with hatred. It was the first time he had actually wanted to kill Fugaku, his own father.

"Itachi, don't!" Itachi halted instantly as he heard Sasuke's sweet, frightened voice behind him. He turned his head to see Sasuke standing in the middle of the hallway, his hands brought to his lips in fear as he watched his family fight. There were even tears in his dark, milky eyes.

"Sasuke…" Itachi got up and left Fugaku to stand and brush himself off, his face twisted with pain and vehemence.

Itachi ran towards Sasuke, who met him halfway, sobbing loudly into Itachi's chest. Their parents didn't even try to interrupt; they didn't know what to do at this point.

"Itachi, I-I don't w-want you t-to be mad!" Sasuke wailed. "I-I'm sorry, I-I…"

"Shh, Sasuke, you didn't do anything," Itachi soothed. As soon as Sasuke needed him, he forgot all about his spat with his parents. As soon as Sasuke was in trouble, everything else wasn't important. "It's not your fault."

Sasuke's tears sparked even more detestation in him for his parents; they had made Sasuke cry, they had started everything. And now…they were going to pay.

"Maybe you two should…should just go," Mikoto suggested tiredly, her face gaunt. Fugaku wouldn't look at any of them.

Itachi didn't answer, just scooped up Sasuke into his arms and hurried upstairs, trying to replace his sneer with a comforting smile for Sasuke. He didn't want Sasuke worrying about anything, nothing at all, so he was going to do this carefully, stealthily. Sasuke wouldn't know, he would never find out. And they would finally be happy, finally not have to deal with Mikoto and Fugaku looming over them all the time.

It was going to end.

Sasuke gratefully let Itachi carry him, clutching his shirt for dear life. He didn't know what had been going on, and that's what scared him even more. What Itachi had done at the lake was wonderful! It made him happy, why should his parents be so disgusted? And what had his father possibly have said to make Itachi attack him like that? Sweet, loving, kind Itachi?

Well, whatever it was, he knew Itachi could take care of it. Itachi would make it all better, like he always did. He wasn't that worried, already feeling a bit more at ease with Itachi with him.

Itachi carried him into his room, setting him carefully down on the bed. He wiped off the tears on Sasuke's cheeks with his thumb, pushing back his mussed hair.

"It's okay, otouto," Itachi assured. "Nothing's wrong, I promise. Everything's fine."

"O-okay…nii-san…I-I believe you."

"Now come on, don't cry!" Itachi tried to distract Sasuke long enough until he fell asleep, then he would do it. He would destroy the one thing that was preventing their happiness. But he couldn't let Sasuke even suspect something, so he had to pretend everything truly was okay. "Tell me about that time in the winter, do you remember?"

"Y-yeah, I remember." Sasuke snuggled up to Itachi on the bed, their legs tangling together, their fingers intertwined.

"Tell me about it. You know how I love hearing it."

"B-but…you've heard it a million times!"

"Tell me a million and one."

"Well…it was two winters ago, you know…" Itachi stared behind Sasuke's head as he told the story of when there was a blizzard so terrible, their door was completely blocked by thick snow. But it was still a great day because they spent it in the dark with candles, eating week-old cookies and making up stories to keep them busy.

Sasuke told it the same way every time, but his voice was so cute when he spoke of the snow, just melting away into the memory of it.

Itachi could tell that, around the end, when the power switched back on, Sasuke was getting sleepy. His voice was getting slower, and he had to stop more often to yawn. Itachi stroked his back to speed it along, feeling Sasuke relax under his hand.

At last, Sasuke had fallen asleep.

Itachi picked his way out of Sasuke's grasp, surprised that he didn't wake him up, considering how tightly Sasuke had embraced him.

He watched Sasuke for a few more minutes, making sure he really was sleeping. He almost couldn't look away; Sasuke was probably the cutest when he was asleep, curling up tightly into a ball, though he was covered in two giant blankets. His bangs were in his face, his mouth open when he breathed.

But he had a job to do.

Itachi tiptoed across the hall to his parents' bedroom, pushing open the door as quietly as he could. He quickly adjusted to the darkness and snuck to the other side of the room to their dresser, opening the bottom left corner drawer. He sifted around inside before finding what he wanted, and pulled it out.

He ran his fingers over the sleek surface of the knife. It had never been used, and probably never would if this hadn't happened. Mikoto claimed she felt safe with it, in case some criminal broke into their house, or something…

He bet they never had to worry about their son using it.

He stood in the doorway, just stood there. Sasuke wouldn't hear a gunshot, or anything. Everything was perfect.

He turned on the light, but they didn't wake immediately. Mikoto stirred, and rubbed her eyes at the sudden brightness, sitting up and looking around.

"Itachi, what are you doing…?" She saw the knife in his hand and narrowed her eyes in confusion. Then she saw the deadly glint in his eyes, and it clicked. "Itachi, Itachi, no--!" But she never finished her sentence.

It was too easy. She was dead before she had time to blink, and that's when Fugaku woke as well, and as soon as his eyes were open, they closed again.

They didn't make a single noise, and neither did he.

Then, just for the fun of it, he stabbed them again, and again, even though they were long past dead. He wore a sadistic smile as blood splattered his face, hoping that they both went to hell, like what they said would happen to him if he continued this absurdity. That's where they would end up, for not letting him get what he wanted.

He even had figured out what he would say to Sasuke once it was all over. It was as if he had been planning this for a long time, waiting for the right moment to come along.

In a way, he had.

And now, as he stood in the dark, his eyes slits as he saw through the blackness, he reminded himself what he did this for.

He wiped the bloody knife on his hand until it was shining clean again, but didn't put it way just yet. He hadn't touched his parents, not leaving any fingerprints, or trace of him whatsoever. He washed his hands with soap a few times, then decided to douse them in bleach to get rid of the smell. His face was also clear of blood, the smell of it completely drained. He then put the knife in Fugaku's hand, deliberately his, more payback for starting this entire thing. He made sure Fugaku's hand was wrapped around it thoroughly, so it was covered in his fingerprints, not Itachi's.

He also changed clothes, stuffing the previous outfit into a paper bag and throwing it quietly into the crackling fireplace; it never went out, especially at night when Sasuke was the most cold.

It burned easily, the fire roaring up against the brick lining. Itachi watched for a while, making sure it was all gone before smiling to himself.

Done.

A/N: Well. There you go. Finally, an update. Happy birthday Kushina! I didn't know how to write anything for her...Naruto's mother...so I just posted something I really didn't want to post.
