Sasuke knows that his brother isn't dead. No matter how good Itachi is with genjutsu Sasuke has a second sense for his older brother.

"Wake up," Sasuke is holding Itachi's hand and the twenty-one year old opens his eyes.

"Sasuke," Itachi murmurs.

Sasuke smirks down at the bloody face of his brother, "I've learned a lot since you told me to hate you. I've learned that you didn't kill our family just because you wanted to 'test your abilities'. Naruto has been behind me the entire time. I'm not 'missing-nin', Aniki. Just like your mission to infiltrate Akatsuki, my mission was to help get rid of Orochimaru. Now I've done that. And now I have you here, under me." Sasuke straddles Itachi's hips gently, making sure that he doesn't hurt the man.

Their fight was, as Naruto would call it, 'epic'. But now he has Itachi under his control, under his thumb, under his body.

"Hn." Itachi smirks back and gives his hips a little thrust up and Sasuke's eyes darken.

"What are you doing?" He asks his brother and Itachi licks his lips.

"I think you want something," Itachi tilts his head a bit to the side and Sasuke stares at the long line of flesh that has been bared to him.

Itachi's hips thrust again and Sasuke smirks as he grounds his body down against Itachi, "You think to disgust me by coming on to me?" He asks, his bangs hiding his eyes from his brother, "You don't know how depraved I actually am."

Itachi's eyes widen and Sasuke leans down and licks the offered neck. Itachi refuses to let the moan leave his lips and Sasuke shoves the Akatsuki cloak from his brother's shoulders.

"Sasuke-kun," Itachi shuddered when Sasuke kissed down Itachi's chest, massaging his chest with his calloused hands.

"What?" Sasuke hissed, "Are you saying you don't like this?" Sasuke brushes over Itachi's nipples and they pebble under his harsh ministrations.

"Sas-Sasuke," Itachi gasped.

Sasuke continues de-robbing his older brother of his Akatsuki cloak. He pushes the black and red material down his brother's arms and pulled the cloak from under the man. Itachi's mesh bunched up around his chest as Sasuke pushed the mess of clothing out of his way. Sasuke flicks open Itachi's button on his pants and shoves his hand down, under Itachi's underwear. Itachi groans when his little brother palmed his half hard cock and stroked hard.

"How's that, Aniki?" Sasuke purrs into his brother's ear. Itachi's hips stuttered against the force that Sasuke was using on his cock and his took several deep breathes to try and calm himself.

"Don't, Sasuke, you don't want to do this," Itachi begs his little brother and Sasuke laughs hoarsely.

"Yes I do, Aniki," Sasuke slithers down Itachi's body, yanking at the pants in his way. He engulfs Itachi in his mouth and Itachi can't help but thrust up into the wet, hot suction.

"Sasu-Sasuke!" Itachi cries out as Sasuke lathes his tongue over the throbbing organ and Sasuke thinks that his older brother is better than him at everything. He even has a better lust-filled voice than Sasuke.

Digging into his weapons pouch Sasuke withdraws a kunai and while he concentrates on working Itachi's cock into full hardness he cuts the pants away. He is too impatient to be waiting around for his brother to get with the program.

Itachi can feel the sharp bite of the blade against his tender inner thighs and he has to stop his hips from moving.

Sasuke drops the kunai next to them and against enters his hand into the weapons pouch. This time he takes out the knife oil and is thankful that it is bio-degradable. Not only is bio-degradable oil good for the blades that he oils, it is also safe for skin contact and relatively safe to ingest so he knows that it won't hurt his brother when he uses it as lubrication.

His hand is dripping with oil and Sasuke smirks up at Itachi around the cock in his mouth and shoves two fingers through the tight muscles under his hand. Itachi arches up with a cry and Sasuke deep throats Itachi with very little trouble. Sasuke is finally thankful for his time with Orochimaru.

Itachi is panting and tears are pouring down his face and his cock is rock hard because Sasuke is massaging his prostate and he's humming and Sasuke knows that a vibrating throat around a hot cock is always wonderful.

"Sasuke!" Itachi cries out again when Sasuke adds a third finger to his ass and Sasuke is careful that he doesn't tear anything. He wants Itachi to hurt, to despise him, but he doesn't want to make his brother bleed. After all, Itachi hurt him, made Sasuke despise him, but never made Sasuke bleed.

The things of the past can be forgotten, but never forgiven.

Knowing that Itachi is ready, Sasuke pops his mouth off of Itachi and flicks open his pants so he can scoot into the vee of his older brother's legs. He is hard already and he grasps himself, lining up to Itachi's entrance. Itachi watches him with wide eyes and Sasuke pushes in.

The tear tracks on Itachi's face are beautiful and when more tears come, Sasuke feels himself get harder. "Gods, Aniki, you are so fucking tight."

"Sasu-Sasuke," Itachi's hips are moving without his permission and Sasuke grins sadistically at his brother.

"You want this, don't you?" He mutters as he ruts into his older brother, "You want me to hate you, to use you, to fill you with my cum. You want to be used like a whore; used like Madara wants to use you, like Orochimaru wanted to use you." Sasuke leans over his brother and whispers dirtily into his ear, "You saved yourself for me to defile, didn't you? You saved yourself so that I could take revenge on you for hurting me. You wanted me so bad when you were thirteen that you had to leave. You wanted to fuck me into the ground when I was eight and you think that you deserve this, don't you?"

"Gods, Sasuke," Itachi thrashes back and forth and he can't push his little brother away. He never could and that was the problem. Having Sasuke in him, having Sasuke dominate him so thoroughly is everything and nothing like what he imagined for the last six years.

Sasuke is fucking him like there is no tomorrow and Itachi can't help up start to fuck back in time with his little brother's thrusts.

"You left me alive so that I could fuck you, didn't you?" Sasuke breathes into his ear and Itachi wraps his arms around Sasuke and holds his brother as close as possible. "You've wanted this for so long that I'm finally giving it to you and you can't stand how it feels, it's like finally having everything you ever wanted, isn't it?"

Itachi lips open in a moan against Sasuke's neck and he feels one of Sasuke's hands encircle his prick and his eyes close. The words that Sasuke is whispering into his ear as though they were gentle words for a lover are undoing him and he just can't stop wanting Sasuke deeper. "Please," He stutters out and Sasuke smirks back at him.

It isn't a nice smirk and Itachi gulps in deep breaths of air.

"Please what, Lover?" Sasuke taunts him, "Please more? Please deeper? Please cum? Please fill me?" Sasuke asks, each question punctuated by a thrust of his hips.

"Yes, yes, yes, oh gods, Otouto! Yes, please," Itachi has never felt this hot before and he jolts when he feels a finger press into his ass next to Sasuke's cock. He looks over Sasuke's shoulder and sees a clone smirking at him and he throws his head back with a howl when the clone adds another finger and it's not long before Sasuke's cock and three fingers are fucking him and he can't help but scrabble at Sasuke's back with his nails, wanting it to stop, wanting more.

"Aniki," Sasuke grunts and leans back, pulling Itachi with him until they're both sitting upright and Itachi is crying into Sasuke's shoulder and he feels less than full when the clone removes his fingers. He doesn't notice what's going on until he feels Clone-Sasuke at his back and the scrape of open pants on his thighs and he realizes what's going to happen only a second before both Sasuke and the clone are thrusting deep into him at the same time.

"Sasuke!" Itachi throws his head back and he feel so full, so stretched and he knows that it's his brother that is fucking him and he can't stand it and he cums thick streams of white onto his chest. Sasuke kisses him and keeps fucking him hard.

Itachi is limp in his brothers hands and he can't lift his head from Sasuke's shoulder and he wonders how Sasuke could possibly keep up this punishing pace.

"Aniki," Sasuke growls into his ear, "My clone is going to come in you," He licks Itachi's neck and bites down hard, but not enough to bleed. Itachi is panting and he nods against Sasuke and he feels a burst of heat fill his ass and he clenches around the liquid and he wonders idly what a clone would cum and then he's too busy being fucked by Sasuke to worry about it.

The cum in his ass is thick and slick and he can feel Sasuke squishing into him and the cum being forced deeper into him. He moans and when Sasuke starts to masturbate him again it hurts but he starts to harden. Itachi sobs into Sasuke's shoulder and when Sasuke speeds his thrusts he thinks that maybe it will be over soon and then he feels more fingers at his ass and tears are crawling down his face because he's sure that he can't handle a second double penetration but there it is and more warm flesh is splitting him apart and Itachi's mind wildly tries to think of who Sasuke could have learned so much self discipline from.

"O-Otouto," Itachi mutters, his head resting against his brothers shoulder, tears soaking the open white shirt that the boy, no, man is wearing, "Please, oh gods, I can't- This is too-"

"Nothing is too much for you Aniki," Sasuke snarls and grabs Itachi's hair, pulling his head back, forcing Itachi to look him in sharingan red eyes, "You're my Aniki, you've always been better than me. In everything. And now you're mine."

Sasuke snarls again and his thrusting is quick and fast and the new clone is matching his pace and Itachi feels like he's going to rip open wide by the two cocks but it's so good and his body is racked with pleasure and he cries out as a second orgasm is forced from him. His mouth his dry and his body is sweating and Sasuke is licking his neck and then the second clone violently cums burning him with the heat from the liquid and he thinks that he can't handle anymore cum in him, he feels so full and it's all Sasuke, all his little brother and he sobs in pain as his cock twitches against his stomach and tries valiantly to harden for a third time.

Sasuke laughs roughly at him and presses in deep and then Sasuke does something with his chakra and his dick seems to grow longer, going deeper into him.

"Sasuke!" Itachi screams as the cum in him feels like it's being pushed all the way into his stomach and he imagines that he can taste his brother in his mouth and Sasuke laughs again.

"Chouji was kind enough to show me a minor body modification jutsu," He says to Itachi and Itachi is far too out of it to realise that Chouji is an Akimichi and that the Akimichis are known for being able to enlarge any part of them that they want.

A chakra infused hand grabs his flagging cock and runs over it down to his balls and Itachi can feel Sasuke caress his testicles brutally, raw chakra jolting into his balls and coursing down his cock. He cries with pain but it's pleasure and Itachi is confused and doesn't know how to react and Sasuke is twice as big and twice as long as he was originally and he can feel Sasuke all the way up into his body and Itachi's chin falls to his collarbones and he stares at his lower belly, which is slightly swollen and he knows that it's the combination of cum and Sasuke's unnaturally huge cock in his ass.

Itachi is sobbing still and he can't stop his dick from jerking with pleasure and it's too much and he's cumming a third time and the pleasure is so much that Itachi almost passes out but can't because Sasuke is still fucking him and running burning raw chakra into his balls. "Please- oh gods, Sasuke, please, no more, I can't, it's too much, I-" Sasuke buries himself deeply into Itachi one last time and it's the furthest that Sasuke has been in him and Itachi thinks that he'll never survive having a cock that deep in him.

"Aniki," Sasuke growls into Itachi's ear and suddenly Itachi is full past bursting with cum and he cries out with the pain. His lower belly swells just a little more as he is filled and he knows that he'll never get his brother's cum out of him. It's gone too deep, there's too much.

Sasuke lets go of Itachi and the older brother of the pair falls to the ground on his back. Sasuke is still inside of him, though he is softening, and Sasuke sneers at him.

"You want my cum. You want it all."

"Yes," Itachi moans brokenly, hands cradling his lightly rounded lower belly. He wants that burning hot cum in him forever and ever and he never wants to lose it.

He was prepared to die on this day. Sasuke has broken him instead.

"Keep it then," Sasuke snorts, "I have no need of it now," He pulls out of Itachi and stares at himself critically. There is no blood and Itachi feels cheated. He should have been ripped open during their encounter.

He wanted the pain.

Itachi can feel his brother's cum slipping out of his ass and he clenches his muscles, trying to keep the cum in him. "Otouto," He breathes, "It's coming out," He's sad and there are new tears because he doesn't want to lose any part of his brother.

Sasuke shakes his head at his older brother and barks out a laugh. "You want to keep it that badly," He says to himself and sighs. "You can't let go of it, can you?"

"No," Itachi whispers, "Please, Otouto, help me keep it in."

"Do you think that I carry a plug around with me?" Sasuke tsks and rolls his eyes. He reaches out and presses a hand over Itachi's, forcing them down on his belly. The cum is forced out of Itachi and the elder of the pair is sobbing, trying to tell Sasuke that he wants it, that he can't live without his brother in him anymore. He's lost everything else, he doesn't want to lose this.

"Oh shut up," Sasuke backhands him nonchalantly with the strength one would use with a civilian, just enough to get his point across, and Itachi chokes back a sob, "If you want it so bad that you can follow me back to Konoha. I can fill you with all the cum you could possibly want there. You can get a fucking plug and keep it in all day. I don't care, but stop being so fucking whiney. Gods, where the hell did my old, stronger Aniki go?" He mutters to himself and Itachi can't bring himself to care.

He's been broken, after all.
