Chapter Four

I think they found another cure
All broken hearts and feeling insecure
You'd be surprised
What I endure
What makes you feel so selfassured?

The next day, both Itachi and Sasuke were supposed to go to school, but they slept in, and Itachi just didn't bother. He didn't think Sasuke would like going to school anyways. They slept extremely late, until about one in the afternoon. The curtains were tightly closed, so they weren't woken by the high sun. It was dark and cool, so they slept soundly for a rare, peaceful night. Itachi awoke randomly, not really sure why he didn't sleep well. But every time he did, Sasuke would be curled up in his arms, his forehead pressed hard against Itachi's chest, his face twisted up as he dreamt. Itachi sometimes considered waking him from his nightmare, but he never did.

So finally, when his limbs were beginning to ache from staying in bed all day, Itachi picked his way out of Sasuke's grasp and tiptoed to the bathroom.

But Sasuke was already awake, rubbing his eyes sleepily as he sat up and stretched, his hair tousled. Itachi had to smile at the pure cuteness of his little brother.

"Where're going?" Sasuke asked sleepily and Itachi held out his hand to help Sasuke off his tall bed, since Sasuke was a bit too short for his feet to touch the ground.

"A bath. Want to take one with me?"

"Yeah…" Itachi led Sasuke into the bathroom and started the bath. They hadn't had breakfast yet, but it was a little late for that. Besides, Itachi thought pleasantly, it was just them now. They could do whatever they wanted, whenever they wanted. He was sure that would speed along Sasuke's consolation process about his recently deceased parents.

He watched Sasuke undress before he did himself, staring at how…innocent he was. Innocent in every way possible. He didn't know anything other than what Itachi told him. Itachi could tell him he was going to grow a tail when he turned 18, and he would believe him. He shouldn't be so ignorant and gullible at his age, but Itachi wanted to shield him from the truth. Reality was too tough for sweet, fragile little Sasuke. His small, secluded world with Itachi was fine.

They slid into the hot water together, and Sasuke sighed, leaning his back against Itachi's chest.

"So how are you doing?" Itachi asked, and Sasuke shrugged.

"I guess…sad…"

"I know otouto, it'll be okay," Itachi promised him. "I'll take care of you."

"I know…" They sat there like that, motionless, silent. No words were needed at first. Then, Itachi picked up a bottle of shampoo and poured some onto Sasuke's head, kneading it into his silky hair. Sasuke hummed in satisfaction as Itachi massaged his scalp, dusting off the dirt that had stuck there from a few days ago, when they were at the lake.

Ahh, the lake. Itachi grinned darkly at the memory. It was bittersweet.

Itachi moved his soapy hands to Sasuke's shoulders, rubbing them softly as well. He saw Sasuke's muscles trembled under his nimble fingers, and he pressed a little harder, loving the tiny moan that escaped. He went lower and lower, until his hands were under the water, massaging Sasuke's lower back. The flesh got softer as he went downward, Sasuke's moans louder. He teased a bit more, before forcefully grabbing a handful of Sasuke's ass. Sasuke squeaked, jumping slightly, causing the water to splash over the side of the tub.

"N-nii-san…" He breathed. "D-don't do that so suddenly…"

"Sorry…" Itachi said, but he wasn't really paying attention. He kept groping Sasuke's rear, while he started nibbling his neck. Now he could do this. Sure, he'd have to take it slow, since Sasuke wasn't used to it, but they had all the time in the world. Sasuke had obviously shown he wanted it as well, though probably not the same way Itachi did. He wanted it because he loved Itachi. Itachi loved Sasuke too, but he also wanted to connect with him on a deeper, more passionate level, skin to skin contact.

But…was it really that far off?

He moved his hand around to touch Sasuke's member, and he jolted in surprise, but let Itachi stroke him. Now that there was no way they could be caught, Itachi let himself go insane.

He stroked and rubbed until Sasuke was in tears, pressing up against him, whining and moaning. Precum leaked into the cloudy bath water, and Itachi ground his own arousal against Sasuke's back.

They could do this whenever they wanted! Itachi realized wildly. Sasuke belonged to him and him only!

With is eyes shining with lust, Itachi squeezed Sasuke dick until he cried out in pain, and told Itachi to be a little bit more gentle.

At first, Itachi figured he should listen to his little brother and go slower, but suddenly, that little voice was extinguished by a bigger, hungrier desire.

The desire to mark Sasuke, to claim him as taken.

It was the one thing on his mind, and he was so driven, he thought Sasuke would get used to it and love it just as much as Itachi did. Of course he would! They were brothers, they loved each other! Sasuke wanted this too!

So Itachi grabbed the back of Sasuke's head and forced him backwards, so his neck was exposed. Itachi leaned down to suck on the pale column, and Sasuke squeaked, wriggling a bit at the sudden pain. Then, he went limp as Itachi bit down roughly, sinking his teeth into the soft, pillow-like flesh, blood dribbling down Sasuke's shoulder. It felt so good to mark Sasuke, to bite down and feel the coppery taste of blood fill his mouth. Part of Sasuke was inside him now, his own blood was sliding down his throat, and he swallowed, licking his lips. What he wanted for so long was his at last, and there was nothing anybody could do to stop him!

Sasuke clenched his fingers against Itachi's arm, gritting his teeth as Itachi continued to nip at his neck. It felt good, sort of, but it hurt more. It stung, and his erection wilted a little, even in Itachi's heated hand.

Itachi oddly didn't seem to notice this. He kept leaving big red hickeys on Sasuke's skin, until it looked almost disfigured, like Sasuke had some sort of disease. Sasuke didn't look down to see for himself, but he could feel the throbbing everywhere.

He didn't think about this. Itachi was just showing his affection, and this was the way he did it. Itachi was a…physical person. Itachi loved him.

Right?

Finally, it seemed like Itachi was satisfied with the damage, and focused on bringing Sasuke to orgasm. Sasuke's neck ached, and he couldn't breathe so easily. But he thought, as long as Itachi stayed with him and took care of him, he could take it.

This time Sasuke would come, Itachi decided. This time, he would have his first real orgasm under Itachi's hands. This time, they would not be interrupted.

"I-Itachi!" Sasuke cried, trying to thrash his head, but his neck forbade movement. Itachi's body felt so hot behind him, his hand burning his flesh, melting him. His parents were dead, but he had Itachi, he had this. As long as Itachi kept his promise, things would get better. He would heal.

Even though Itachi was creating new wounds.

"I-I'm…Itachi!!" Sasuke arched his back and came, and a huge crooked smile twisted onto Itachi's face. His hand became covered in Sasuke's seed, connecting them, binding them.

Forever.

Not much else happened the rest of the day. Exhausted, Itachi had carried Sasuke from the bathroom to their room and dressed him, admiring his naked beauty. This perfect boy was his. The puncture holes on his neck had stopped bleeding and were accommodating to the sting, but they were still so obvious. Red and glaring, it was as if Itachi had written his name all over Sasuke's flesh. So the world could see that Sasuke already had a brother, a master. A lover.

They ate breakfast and lazed around, cuddling, talking. Nothing much.

But that night, Itachi was in the mood again.

Sasuke didn't know what to say, really. He didn't want to refuse his brother, but he also really didn't want to come again. Once was enough for him in one day, he was still young and inexperienced. So he said something.

He expected Itachi to just shrug in disappointment, but not do anything Sasuke didn't want to do.

But that's not what happened.

Itachi had pinned him on the bed and straddled him, leaning in close to lick his jaw.

"Itachi…"

"Shh, otouto," Itachi said quietly. "Everything will be fine." And for Itachi, it would. He could see the confusion in Sasuke's eyes, but confusion was natural. He would have to learn that being with Itachi meant multiple orgasms at a time. He could understand why Sasuke couldn't do that, but that thought wasn't on his mind, strangely enough. Before, he would have done anything Sasuke had asked. But now, he felt in control, and Sasuke was powerless. He could do anything he wanted! At last!!

He stripped off Sasuke's shirt and attacked his chest, pulling at his nipples until they were red and perked.

Sasuke whimpered in discomfort as his body was slobbered over, but he reminded himself that it was Itachi. It was okay.

Itachi abruptly bit down on Sasuke's nipple, and he cried out in pain as blood trickled down his chest and then his hip. He placed his hands on Itachi's head and tried to push him off, but of course, Itachi was stronger, and did not budge.

Itachi's mind was being clouded by his own scent of arousal, and he hardly heard Sasuke's cries of disapproval as he marked and bit at his skin.

Tears spilled down Sasuke's cheeks, pain making his fingers tremble. Why was Itachi hurting him like this? Was this the way he showed his love? If it was…Sasuke didn't know if he could take it. This was the third time he had been ravished by Itachi, and already, he knew it would get more forceful. He reminded himself that Itachi was his brother, and they shared a bond that normal lovers did not have.

Itachi moved down from Sasuke's chest to his stomach, scraping his teeth along his flat abdomen. Then, he tugged down Sasuke's pants, ripping them off his ankles and throwing them aside. Next came his underwear, and Itachi stared at his flaccid cock with narrowed eyes. Sasuke swallowed nervously, hoping his discomfort didn't offend Itachi.

But after a few moments of silence, Itachi bent down and devoured Sasuke's member into his mouth.

Sasuke threw his head back, biting his lip to hold back a scream. Itachi's mouth was hot and wet, slicking up Sasuke's cock until it began to grow and throb. Sasuke whimpered, laying limp as Itachi's sucks got faster and harder. Sometimes, he would bite down, getting Sasuke's attention once again. He didn't know he could bleed there, but he found out soon enough.

"I-Itachi…" Sasuke sobbed, tangling his fingers into Itachi's hair. "P-please…b-be gentle…" Itachi paid him no mind. Instead, he reached his hand around Sasuke's thigh and slid his hand between soft pale cheeks, searching for the bud he wanted.

Sasuke gasped as cold fingers touched him, and he shook his head frantically.

"T-that's--! I-Itachi, that's…weird!" Itachi still ignored him, circling the tiny hole with his fingernail, memorizing its location so he could access it easier in the future. The feel of Sasuke's skin drove him mad with desire, and he felt his erection give a painful throb, longing to be inside his little brother. One way or another, he would get what he wanted.

Before Sasuke could register it, Itachi's finger was shoved inside him. Pain shot through his spine, and he wriggled wildly, trying to get Itachi to move away. Itachi popped his mouth of Sasuke's shaft and licked his lips.

"It's alright Sasuke, just relax," he said quickly, his voice sounding high with pleasure. "Just relax, I'll make you feel good! I promise, just lay back." Sasuke's eyes shone with fear, not recognizing Itachi as his brother anymore. He was different. Crazy.

He was breaking his promise.

Itachi moved his finger around, thrusting it, scraping against thin muscle. Sasuke's face was red and glistening with tears, wanting it to be over.

It was, as Itachi brushed something inside Sasuke with the tip of finger. Sasuke screamed until his lungs burst, coming in just a few, weak spurts. It squirted onto Itachi's chest, while he gazed at Sasuke with his eyes glittering with something Sasuke had never seen before.

As Sasuke panted, slowly returning from his awful high, he realized something.

Itachi changed.

A/N: Well. This is as far as I've gotten. I have an idea on how to continue this, but it's going to be really difficult...
So now you understand what it's really going to be about. Sad and angsty. I'm not going to tell you what happens [what's the fun in that??] but I will warn you that it gets scary. So prepare yourself.
This is where Itachi's perspective ends. For the rest of the story, it's going to be mostly in Sasuke's perspective.
I've had Prisoner by Jeffree Star stuck in my head for the past few weeks, so...I'm a bit hyper XD I'll give a cybercookie to anyone who knows that song ^^
