Chapter Twenty Five

The Uchiha's True Curse

Sasuke stares at the ceiling of his prison cell in the hospital, drained of all his chakra by the seals they put on him, he can only fume about how it's not fair that he the great Sasuke wasn't allowed to do what he needs to avenge his family honor.

That bitch Itachi needs to die, die by his hands and his alone, only then will he feel any relief from this burning pain. He remembers that night before the massacre, when the pain started to eat at him, he goes back to that fateful night, he hears Itachi arguing with Father. Sasuke knows he shouldn't eavesdrop, but he hides outside the door to his father's study anyway, listening.

His father makes a sound that Sasuke might think was a laugh, if only he had ever heard him laugh before. "We are Uchiha," he says. "We have a bloodline to keep pure, the world's strongest Kekkei Genkai to protect. What would you have me do, Itachi? It is your duty to marry your bother like I married my sister to keep the blood pure." Knowing this to be true but hearing it spoken out loud still shocks Sasuke knowing this is a forbidden act in the village of the leaf.

"No farther! I will not, it's not right." Itachi's voice is low and full of anger. This old argument, years in the making has finally come to a head. She has spent years away from the clan on a thousand missions and the conditioning, some would say brainwashing has faded away.

"We do what we must Itachi, I know he is young but four years is not that much, it will get better as you both grow older." the older man says. To admit to her this was wrong would invalidate his whole life and that of his beloved wife and that he would not do.

"It would have been so much easier for you if he had been born first." she says with venom, "A meek little girl you can breed like a horse. Well I am not MEEK!", a sound that is almost crying reach Sasuke but Itachi never cries, she is the prodigy of the clan, the best of them all.

"I am an Anbu captain now, you can not force me." Itachi's voice is cold and strong once again. "I will marry Shisui and you can not stop me." Sasuke knows Itachi and those word are meant to put an end to this argument once and for all.

Fugaku was a strong man with strong convictions, it does not pay to go against him. Itachi knew this but she didn't know to what degree he would go to get what he wanted.

Sasuke hears the familiar squeak of his father's chair as he leaned back into the leather. "Itachi you know Shisui is not of pure blood. He is not even fit to marry back into the clan and especially someone as pureblood as you."

Sasuke feels a coldness flow through the door as Itachi chakra radiates from her form in waves of anger. He is now frozen in place with his ear pressed to the door unable to blink much less run if need be.

"Only someone of your pure blood will be able to calm Sasuke when he comes of age, if you deny him your touch he will suffer, is that what you want for him?", said father from behind his large desk.

Itachi knows the stories from the ancient scrolls, only those women of pure blood have the right chakra to prevent the chakra madness of a male of the same. That is why only her family is the last of the pure blood, all others having died out in battle or in madness. All other Uchiha married within the clan among the many branches, some more pure than others but none able to reach the pinnacle of power pure blood give their eyes.

Shisui being of the least of the blood, being a half Uchiha and whatever bastard raped his mother on the battlefield. She hide the truth from all until it became clear his father was not the fallen Uchiha she claimed him to be.

In a fit of anger, Itachi says, "I don't care about Sasuke, I love Shisui and I will bare his children." Unknown to her a small boy's heart breaks and a seed of anger grows within him. An anger that will soon grow into something all consuming in the coming years.

"No Itachi you will not, I received a report today that the S-rank mission I sent Shisui on was a failure and cost him his life." Sasuke hears the sound of a scroll hitting his father's desk in front of Itachi.

The wave of chakra blows Sasuke over as it rattles the house. Looking down Sasuke can see he pissed his pants like a small child untrained in the ways of an adult.

"You will pay for this father, you all will pay." Say Itachi in a voice filled with ice and rage, as she vanishes in a murder of crows. The pressure of her chakra fades and Sasuke rolls to his feet and runs away to hide in his room, confusion and anger fills his world as he pulls the bed covers over his head.

Remembering that day and the next full of blood and screams of the clan Sasuke renews his oath to kill that bitch and then end his own life as he could not stand the idea of being the father of unpure halflings.

Having fallen asleep Sasuke is jolted awake by a finger running down his cheek. His eyes spring open and he finds himself face to face with that murdering hateful bitch. When he tried to lunge at that hateful face he finds he can't move a muscle.

"I am going to KILL YOU.", he tried to scream but it come out as a whisper.

It has been almost four years since the last time he laid eyes on her. The wiry sixteen-year-old he remembers has been replaced with a more feminine form. Dressed from head to toe in a skin-tight black bodysuit the Anbu favored absent the armor, her lithe body and toned muscles didn't take away from her femininity but seemed to enhance it.

From her long black hair that hung down to her waist tied at the end with a black ribbon and a deadly steel ball, to her womanly bust, small waist, and flared hips she looked the part of an elite assassin or alluring spy.

"Now, Now, little brother don't talk like that." a smiling Itachi says as she draws an invisible line of chakra over Sasuke's face and down onto his neck. He struggles with all his might and can't move even a finger. He tries to call on the curse mark and finds it is gone but for a residue of tainted chakra throughout his system.

With a wave of her hand she draws the hospital sheets down to expose Sasuke's prone body. The sterile hospital gown covers his gray skin from neck to knee in a mockery of white. Using a kunai Itachi runs it down his body slicing open the gown to leave him naked for the world to see. The gray skin and black tattoo-like marks still cover most of his body from his fight with the looser.

As Itachi continues to play her finger down his neck and begins to draw intricate designs over his chest he grunts out.

"What are you doing, bitch."

"Such talk little bother, you should respect your older sister, after all, I am the last female of the pureblood you so desperately want to protect." she doesn't really look at him and has an air of casual indifference as she continues drawing her invisible lines.

"When I get out of here Orochimaru will train me to kill you in the most painful way," he says.

"Oh I think not, Orochimaru had already taken a body before you even left the village. He found a much more suitable host than a psychotic Uchiha with family issues." the small smile he sees on her face burns into his soul.

"Then I will find another way, someone else to train me." he was almost unable to finish his words as she had reached his pelvis and was now drawing smaller and small designs around his groin. Having never been touched by another human in this area he was totally unprepared for the erotic nature of the act.

His self-imposed isolation has left him vulnerable and he cursed his reaction to her touch.

Having finished her detailed work around his genitals she continued down each of his legs watching to see if there is any sign of arousal. Surprisingly it was the inside of his left knee that finally broke through his loathing for her, the emotional walls around his mind didn't control all of him it seemed.

It started out as a small movement and then slowly grew until he was more than halfway aroused.

Having finished the last line around his big left toe she stood tall next to his side running her eyes up and down his body checking her work for any flaws before continuing.

"Orochimaru did send his flunky Kabuto to the hospital to capture you so he could study your eyes before pulling them out. As I had other plans for you I sent his body back to Orochimaru piece by piece with a little note expressing my displeasure." the casual way she stated her protection of him, in almost a flirting way gave Sasuke a feeling he hadn't felt in a very long time. "Is this what being cared for feels like". He thinks.

"I visited the old Uchiha temple, I see you have been reading the ancient scrolls, looking for a solution to the pureblood problem I believe?" not waiting for a response she continued with her hand placed firmly on the middle of his chest focusing her chakra into the palm of her hand.

"It took ten generations of inbreeding to produce the first one and it would take ten more to do it again if you took a non-Uchiha wife." Seeing the look on his face she presses harder, " Yes, I see you know that but you haven't tried, even with girls throwing themselves at your feet."

Her hand burned his skin and his body was heating up every second she left it there as she pushed her chakra into him. He could feel a warmth spreading over his skin with a strangely exciting feel, he could sense he was getting harder, and as much as he tried, he couldn't stop it.

Looking down and seeing his current state put a different smile on her face as she leaned forward until he could feel her breath on his cheeks. Her musky smell filled his head, it pulled at him trying to draw him to her.

"I know farther told you about the need to keep the blood pure, about how the need inside you would drive you mad if you didn't join with me, that only another pureblood would calm you, but did he tell you how that same need deep inside you also affects ME!" yelling that final word she stands tall and drives a massive amount of chakra into the seal she had meticulously draw all over his body.

His world turns into a kaleidoscope of pain as the remaining chakra from the curse seal is forced out of every pore of his body. Arching his back so only his heels and head are still touching the bed Itachi holds him down and watches the black tattoos fad away and fall to the floor like slim from a swamp.

Kicking the discarded gown over it, the slim, sensing some residue of Sasuke collects into it. Using a wind jutsu to push it out the window and casting Amaterasu it turns to dusk long before landing on the ground.

'Now it's time', she thinks, to deal with her own demons, she holds Sasuke still until he comes to and once his eyes focus back on her, he sees a true smile on her face. "Wasn't sure that was going to work." she jokes running both hands over his now white skin and his strong pecs. The Nine-Tail killed the spirit but didn't seem to care to remove the remnants.

For some reason, her voice sounds seductive lacking any of the hash tones he heard before, she seemed brighter now and less threatening.

"The curse seal made you psychotic dear bother, clouding your mind so you could not see me or the world as it truly is." her voice resonated within him, and an unknown need fills him with unusual desires.

"Now to deal with OUR real problem," she says seductively placing a small kiss on his neck and working her way down his chest until finally, Itachi takes his cock in her hand, and just like that, unravels him into a mass of nerves.

She leans forward, kisses the blunt tip, and the softness of her lips has him biting back a groan. His father never told him about this part, only the duty and honor of the clan but when Itachi takes him into her mouth he can't help but gasp. Finding he can move Sasuke puts his hands in her hair, cradling her head as she sucks on him. It takes all of his willpower not to just thrust and explode in her mouth, but he finds strangely he doesn't want to hurt her. She grows more confident, taking him deeper, and it feels so good. After a life of pain he can't keep control much longer, not with her working him like this.

With all seven inches down her throat, she pulls back and does it again, the fire in both of them consuming any form of rational thought being replaced with only an all consuming need.

Losing any pride he has left he pushes her head down and firmly holds her there as he releases a lifetime of pent-up passion. All he can see are stars flashing before his closed eyes as he pumps everything into his sister's throat. Feeling her struggle he allows her to lift her head but she stops at the top of his manhood and sucks every last drop from him. Unknown to him her chakra network is on fire with his essence, like oil on a fire, it calms for a moment and then flares up again ready to consume more.

Still hard and wanting, he watches her remove her clothes and then straddling him, she lowers herself down, consuming him in one thrust. Unable to restrain himself he meets her every downward motion with an upward thrust of his own. Using his hands on her hips to help balance her they frantically move, trying to find ecstasy to replace a lifetime of pain. The wide eyed look on her face is a mixture of joy , lust and sadness as she knows she is fulfilling her fathers last request before he died.

She falls forward and kisses him and as their tongues duel he feels her spasm and tighten around him, looking him in the eye she moans out she is cumming. The feel of her lithe body shaking in bliss makes him join her until they are both spent. He can feel their combined fluids spilling out of her and down his balls. Her weight on his chest is comforting and feels so right he is torn between holding her and pushing her away. Her spasms around his member changes his mind to a third option.

Sasuke pushes her onto her back and settles on top of her. His weight is warm, heavy, pinning her to the bed. She runs her fingers through his hair and wraps her legs around his waist. He isn't trying to make love but it almost feels that way as he begins again to move within her. He kneels up and continues to move all the while looking down on her. She feels there chakra networks have aligned and the harmony they both have been seeking has been achieved, the old scrolls talked about this but she didn't believe it would feel like this.

There now bright red eyes lock together and he paws her breasts and pulls on her nipples enticing small cries of pleasure from her. Holding a breast in each hand he thinks in the back of his mind how small and fragile she seems. The force of his blows shakes the bed as he uses her as she is using him to satisfy their lust. He can see sparks of red star dust form around them as they get closer to completion, a glow of power and yet soft and gentle in its nature surrounds them.

Falling into her they lock lips once again but this time it's him who declares his climax by grinding into her and filling the void she has had for years. Hovering above her on his hands she sees for the first time a look of contentment and almost a hint of a smile. As the glow around them fades and then the world returns to normal it is the sound of there deep breaths gasping for air that now fills the room.

Slipping out of her he lays down by her side and stares at the ceiling again. "We are so fucked you know that," he said with a little grin at the edge of his mouth.

"I know little bother, Oh I know", is her soft reply.

Do we want more Itachi and Sasuke?
