Okay, so this is really pretty dark. I had gotten this stuck in my head and I needed to write this.

Basically, Itachi became addicted to Heroin because he just couldn't handle it anymore. The pressures from the clan, his parents, the village. He was 4 when he first started seeing death for goodness sakes. But the straw that broke the camel's back was the death of his lover, who is Shisui. He began his drug addiction at 19. Only recently has it gotten out of hand. His parents don't know, nobody knows. Just Sasuke. Always Sasuke.

Addiction

Diacetylmorpine, diamorphine, Junk, Hell dust, Thunder, China white. It is all the same. It is all the big H; it is Heroin. It is a semi-synthetic opioid drug that is synthesized from the ever lovely lady morphine, a derivative of the opium poppy. Heroin really came into her beauty when Germany's company, Bayer, put it out as drug to combat morphine. Those fools didn't know what they were making. If the higher ups made anything that was perfect, its name would be Heroin.

Itachi quickly made his way to his bedroom and quietly shut the shoji door behind him. Striding towards his bookshelf, Itachi fingered each in turn, looking for a specific title. Taijutsu Basics seemed to jump out at Itachi's shaking hand. Tugging the book out of its place on the shelf and hugging it to his chest, Itachi glided his way towards his impeccably clean desk. Letting the book fall open on the desk, Itachi sat in his chair, itching his inner arms through the long sleeved shirt he was wearing. Dipping his hand into the hollowed out book, he brought out a rolled piece of cloth. Moving the book away, Itachi slowly began unrolling the cloth, exposing its contents to Itachi's stormy gray eyes.

Spoon. Lighter. Water. Syringe. Rubber tubing. And one lovely stamp of heroin. Itachi threw a glance over his shoulder at his door. Good, Sasuke hadn't noticed that he was he was gone yet. By the time his otouto came to find him, Itachi would already be gone. Hopefully.

Turning back to his desk, Itachi set to work. He began rolling up his sleeves, well past his elbows, hardly taking in the scars, rashes, bruises, and needle bumps that littered both inner arms. Itachi scratch his arm without a thought. It was just the "itchy blood" symptom that came with withdrawal. It had been two weeks since he last shot up; Sasuke had made sure to attach himself to Itachi at any time he could, preventing Itachi from getting what he needed most. Like a professional, Itachi placed a small amount of water onto the spoon and carefully place a few small crystals of the Heroin onto the spoon. Being even more careful, he picked up the spoon and lit the lighter, placing it under the spoon, moving it slowly to evenly heat up his beautiful concoction. Itachi could only become inpatient as he watched the crystals slowly melt in to his liquid life. They just couldn't understand!

There! It's done and it is beautiful.

Setting the lighter aside, Itachi snatched up the syringe and sucked up the beautiful liquid that lay in the spoon. The colour of his liquid lover was that matching of his once real lover's eyes; dark brown, almost black. Once the syringe got every last drop that it could, Itachi set it down like a precious item and tied the rubber tubing around his upper arm, the veins already popping for what they so dearly missed. Reaching for his escape, Itachi lined the syringe's needle up with a vein that ran through his inner elbow.

Just as he was about to plunge the needle into his arm, Itachi's door broke open and an angry Uchiha flickered to Itachi's side, grasping his now fragile wrist in a bone crushing grip. The syringe was ripped from his clutches and a stinging smack made its way across his cheek. Itachi could feel the blood that was pooling in his mouth, but he didn't strike back as his attacker. Instead, he slowly turned his head towards Sasuke and gazed into the fiery, angry, scared, and tear filled eyes of his younger brother.

"I-I'm sorry Aniki! I didn't mean to hit you!" cried Sasuke softly as he backed away from Itachi. Turning from his brother, Sasuke walked out of the room for a moment with the syringe in hand. When he returned, Itachi had moved to the center of his bed, sitting cross-legged and staring out the window of his room. Sasuke made his way over to the edge of the tatami mat and stood there for a moment, before he went to his knees and crawled to his brother. Shyly, Sasuke looked through his bangs and moved to sitting on his knees, placing a hand on his brother's slowly hollowing cheek.

Itachi leaned lightly into Sasuke's hand. Sasuke was his solid ground now; keeping him up and out of the darkness that threatened to consume him. His otouto was determined to break Itachi's habit, even if it meant Sasuke getting hurt in the process. He would do anything to stop Itachi from going back to Heroin. Itachi could only sigh at the look Sasuke held. Reaching out his own thinning hand, Itachi wrapped his hand around Sasuke's pale wrist and tugged the boy onto his lap.

"Aniki! I can't sit here! I've gotten much too big!" said Sasuke furiously as he tried to pull away from his beloved older brother. He pulled back as hard as he dared while sitting in his delicate brother's lap.

"Sasuke, I only look fragile," smirked Itachi as he wrapped his arms tightly around the struggling boy, "You should know better than to think that I may be delicate." Sasuke stopped his struggling, if reluctantly, and allowed Itachi to pull him against his chest. Itachi rested his chin atop Sasuke's head and let out a sigh that ruffled the unruly locks. He slipped his hand under Sasuke's shirt and rubbed tiny, comforting circles along the jutting hipbone.

"I'm sorry for putting you through this Sasuke," whispered Itachi, squeezing the hip slightly. Sasuke only pressed himself closer to his Aniki. "You hid the syringe well this time, right?" Sasuke nodded slightly and shifted in Itachi's lap, grabbing his left wrist subconsciously.

It had been when Sasuke first realized what was going on with Itachi. Sasuke was 17 at the time and Itachi was 22. It was a year ago that Sasuke stole Itachi's Heroin and hid it in his room; their mother had found it when she was cleaning the younger's room. She took it to their father. Neither of them had ever seen him so upset in their lives. Sasuke was sure he was going to die that day. Itachi was sure he was going to see Sasuke die that day. Luckily, Sasuke just got away with a severe beating and a broken wrist. Every time Itachi tried to speak up and say it was his, Sasuke only shouted over him, claiming to their father that the drugs were his, no; Itachi didn't know anything about it, yes; he had just started using them, that's why there weren't any bruises, no; he wouldn't tell them where he got them from, no; he wasn't scared of the consequences because it would look bad for the Uchihas, and yes; he'd quit or be denounced from the Uchiha clan.

Itachi pulled away from Sasuke and clasped the boy's chin with the hand that wasn't rubbing Sasuke's hip. Tilting his otouto face towards his, Itachi slanted his lips over Sasuke's, taking in his essence. Sasuke sighed and relaxed into Itachi's grip, grasping the front of his brother's shirt.

Shifting around quickly, Itachi laid Sasuke's back against the tatami mat, all without breaking the kiss that was becoming heated. Settling himself between his brother's thighs, Itachi grasped the bottom of Sasuke's shirt and began to slowly work it up the boy's body. "Promise me that you'll try your best to always stop me?" The shirt was off and thrown to the side, while Sasuke let out a whispered, "I promise."

Trailing his hands down Sasuke's pale torso, Itachi arrived at his pants and began to unbutton the bottoms. "Promise me you that you'll always be there for me when I come down?" The pants were thrown aside, landing some place near the shirt. Sasuke arched into his brother's touches, a whispered, "I promise," falling from his lips.

Curling his fingers in his brother's boxers, Itachi placed a light kiss on Sasuke's stomach as he pulled down the underwear. "And do you promise to always love me?" Sasuke whimpered, "I promise," as Itachi flung the boxers away from them to land amongst the gathering clothing.

Sitting up, Sasuke grasped the bottom of Itachi's shirt, "Do you promise to try to stop?" Itachi said nothing and the shirt was gone. "Do you promise to think about me when you go for your shot?" asked Sasuke as his breath ghosted against Itachi's collarbone and his fingers worked the buttons of Itachi's pants. "Do you promise to get better?" Sasuke dragged Itachi's pants and boxers down to his knees, and Itachi kicked them the rest of the way off. Wrapping his arms around his brother's neck and legs around his brother's waist, Sasuke laid back against the mat, pulling Itachi to cover his body. "And do you promise to love me forever and always?"

Itachi placed a kiss onto his Sasuke's lips and whispered against them, "That I can promise."
