Author's Note: Taito. Though, be warned, Taichi and Yamato are half-brothers here – therefore, it is INCEST. Gasp. There are also acts of cruelty, abuse, rape, and the like – so please don't read any further if you think you can't stomach that. This is definitely an "M" rating.

As stated, this will end a Taito. But the other major coupling – or rather the coupling acting as an obstacle before (between?) Taito – is Kenato. Ken is the same age as Taichi, and they're a year older than Yamato. There are also three "main" original characters . . . they're Taichi and Yamato's older brothers. They exist to cause problems! (I didn't want to use other existing characters for the "roles".)

So this is AU, of course. Taichi and Yamato will seem out of character because they were brought up differently – but hopefully their "real" characters will emerge throughout future chapters as the story progresses . . . at least I am hoping to flesh out their characters to mirror similarities between their canon selves. Yay! (I will probably fail. orz)

Disclaimer: I don't condone incest or any of the acts written (except homosexuality, of course). Thinking that they actually occur in real life makes me sad. Well, incest doesn't make me sad . . . just disturbed. So why did I write it – especially considering Taichi and Yamato aren't brothers in any way in canon? Well, because incest in fiction is kinda sorta hot. And it makes the story emote better, I think. Or I just felt like writing it. Ahem.

(Again I stress the "M" rating. You might be disturbed.)

Onwards!

1. XY: One

Taichi Yagami observed his younger half-brother from his view on an adjacent couch. The television was tuned to some mindless soap opera, though like Taichi, it didn't seem as though Yamato was paying much attention. His eyes were directed at the screen, but they were dull and glossed over, allowing Taichi's eyes to roam freely over the other boy without being noticed.

Yamato's mother had been Caucasian – at least in part – because Yamato had light skin that seemed to glow; the result of an oriental mixture with their father's full Japanese blood, Taichi guessed. Half-casts were always so striking, and Yamato definitely wasn't an exception. Unless, of course, he was exceptionally more beautiful.

He had silky blond hair that seemed to change in varying shades and tones depending on the light they were under – as if his hair somehow knew instinctively how best it would look in any situation. His eyes were an intense sea of blue; dark, and yet they seemed like glass almost – crystalline. Taichi didn't know how that was possible. They were framed by lashes just a slice thicker than most boys; and in direct opposition, his eyebrows were just a shade thinner than those of the same gender. His perfect features contrasted heavily with his pale, radiant complexion.

He looked exotic.

But Taichi didn't know why he was so fascinated with the way Yamato looked. Was it because he was so different?

Taichi and his older brothers all had dark features like their father – dark hair, dark eyes, dark skin. And here Yamato was, created by the very same father, all fair-skinned and pretty – he obviously took after his mother.

Gorgeous.

Taichi sometimes wondered why Yamato's mother hadn't wanted him, apart from obvious reasons such as his being the child of a married man. Were her decisions on leaving Yamato in his best interest, or her own? If it was the former, Taichi noted, she had made a grave mistake.

Natsuko Takaishi had abandoned Yamato shortly after he was born, forcing their father Susumu to reluctantly take him in. Taichi's mother Yuuko had tried to cope with the fact that her husband had fathered a bastard child during a drunken one night stand, but ultimately couldn't – she took her own life after only a few months, aghast at her husband's infidelity, and the existence of a child they had not together created.

Their father had turned to alcohol as his escape. He had loved their mother deeply, and heavily regretted his alcohol-induced night with Natsuko – Yamato was his biggest mistake, and it had cost him his wife. He had five sons to raise by himself.

Yamato was only a few months old, Taichi barely a year old, Eito two years old, Toru six, and Hideki ten. Hideki, being the oldest, took on the role of parenting his younger brothers amidst his father's break down, with some help from Toru. Like their father, Hideki and Toru regarded Yamato coldly, even though he was just a baby – Yamato was, after all, the cause of their mother's suicide.

Their father had soon developed a violent side to himself, with the aide of alcohol no doubt, but Taichi could not recall a time when his father had ever hit him or his older brothers. Just Yamato. And he recalled a lot of them.

The earliest memory Taichi had of his father's abuse on Yamato was when he was about four. Yamato was only three, and he had spilt some apple juice on the table. Their father had grabbed Yamato up by the hair, and slapped him hard across the face. Yamato had cried, and sobbed for hours.

Once, Toru had gotten into a fight at school. Their father had yelled at him, then called for Yamato. At five, he got the beating meant for Toru. Another time Taichi had dragged Yamato with him to the park after school, and they had only started for home when it was getting dark. Since they were only eight and seven, that was too late a time. Only Yamato was hit.

On Hideki's nineteenth birthday, their father had gotten slightly drunk, and had decided to show his sons how to have sex – never mind the fact that he knew Hideki was already sleeping around.

He had grabbed a few condoms and some lubrication, and gathered his sons in his bedroom. He took hold of eight-year-old Yamato and plopped him down onto the bed, before removing his youngest son's clothes. Yamato knew what was coming – his father had been doing this to him for some time, though never in front of his brothers until then.

Hideki, Toru, Eito and Taichi had watched as their father opened the front of his pants and rubbed his penis to gain an erection. He had placed a condom onto his shaft, then slathered lube up and down all over his length, then grunted at Yamato.

Yamato knew what to do – he placed his hands up around his inner thighs to spread his legs further apart, then made a bowel movement in preparation for his father's large penis.

Taichi and Eito had looked astonished that Yamato knew what to do from a mere grunt, but Toru and Hideki had looked less impressed – they had suspected for quite a while that their father had been sexually abusing their youngest brother.

Yamato had whimpered loudly when their father inserted only about half of himself inside. He told his sons that considering Yamato's age and size, any more would be too much for him, and that he didn't want to break him – but girls their age would certainly be able to take their entire length.

The other boys had watched as their father gripped the bottom half of his penis with his hand, to stop further than four inches going in, as he moved in and out of his son. Yamato was whimpering and panting and trying not to cry, his cheeks tinted red from the new audience.

After their father had finished, to Yamato's dismay, he had let Hideki and Toru fuck him. Eito and Taichi did not, however, as they were only nine and ten. But they had observed, and Taichi couldn't forget the overwhelming surge of emotions running through him.

Of course at the time he had no raging hormones, so the experience of watching had been in no way. . . sexual. But Yamato was obviously in pain, and the act had been different to just physical abuse, so Taichi didn't know how he felt about it exactly. He was torn between being intrigued, and confused as to whether it should have happened in the first place. He never said anything though.

Three years after that their father had crashed his car whilst driving home intoxicated. He was killed instantly.

Because Hideki was twenty one, and considering the ages of the others, the courts had given Hideki full custody of his brothers, as opposed to sending them to different foster homes. Yamato had been eleven, Taichi twelve, Eito thirteen and Toru seventeen.

Since their father was gone, it would seem like things would look up for Yamato – but he had always clung to their father, regardless that he had physically and sexually abused him on a regular basis. Yamato knew no other way of life – their father had always treated him like that, and he knew his place.

In rare instances, their father would treat Yamato like the others and even tell him that he loved him. That was enough proof for Yamato to think that their father did love him, in some twisted way. Yamato didn't know it before he died, but their father had acted as a sort of barricade between Yamato and his brothers – Hideki and Toru in particular.

They had all been mean to Yamato growing up, as their father allowed that, but they weren't allowed to cross certain lines – their father was the authority figure, and he had final say in everything. Yamato was protected from what Hideki and Toru could've done to him during those years.

But after their father died, Hideki was the alpha male, and no one was there any more to restrict his actions. He was free to do what he wanted.

When their father had beat Yamato, it was maybe a few swipes to his face, and a couple of kicks and punches to the stomach. When Hideki and Toru beat Yamato, it was more alike rough street fighting – grabbing him, pulling him, pushing him into walls – with numerous kicks and punches. And their beatings lasted longer.

They raped him more often, too. Eito and Taichi were both now old enough to join in, though very rarely did Taichi participate, and even then he'd just make Yamato suck him off. He had never anally penetrated Yamato. Taichi didn't know why exactly, since it was no big deal to the others – it was just another way to hurt and humiliate the blond.

Taichi figured he was satisfied with just hurting Yamato with words and cruel treatment, and didn't have to sexually abuse his younger brother just to make it clear how powerless Yamato was against him.

But why had he always been so fixated on staring at Yamato since they were little?

Yamato diverted his gaze from the television screen as he felt eyes on him, and glanced at Taichi, of course catching his eye. He quickly turned back to the screen, before glancing back at Taichi a moment later to see if he was still looking at him. He was.

"What are you staring at?" Taichi accused, even though it had been he who was staring at Yamato.

"Nothing," was Yamato's quick, unassuming reply, not wanting to start something.

Taichi liked Yamato's voice, even when it sounded so small and hesitant. He imagined it would sound smoother, silkier – when Yamato wasn't so on guard.

"Oh yeah?" Taichi retorted in a familiar challenging, gruff tone he so often used on Yamato. "What's been happening on the show, then?"

He didn't think Yamato would know – though, neither did he. He had been busy staring while Yamato's mind had been off in space. Yamato could lie about what was happening, and Taichi wouldn't know – but Yamato didn't know that.

Yamato opened his mouth slightly, then swallowed, before attempting to answer. "I . . . I don't know . . . sorry." Yamato ended his lines often with an apology. Taichi had always found it slightly amusing.

"So you were staring at me," Taichi stated, knowing this was untrue, but not caring. Yamato's face scrunched up in confusion, as he had thought he had caught Taichi staring at him.

"No . . ." Yamato started, though unsure of what to say next without stepping on Taichi's toes. "I was just thinking about stuff . . ." He chose not to imply that Taichi was the one staring, hopefully letting the subject drop.

"Why did you look at me whilst thinking of 'stuff', then?" Taichi didn't let it go, curious as to what Yamato would say.

Yamato raked his brain to think of something unoffensive, though that was pretty tough since his brothers always managed to twist something completely innocent into an insult. He came up with nothing, since he figured if he lied about what he was looking at, Taichi would turn around and say he was the one staring at him after all – and thus he would have had just lied to Taichi. In which case, Taichi would probably hurt him. So he stayed silent.

After several more seconds of silence, with an unimpressed eyebrow raised, Taichi spoke, "What were you thinking of?"

"Just . . . school stuff . . ." Yamato replied slowly. He really wanted the conversation to end before Taichi got the chance to get really annoyed.

"Oh, yeah?" Taichi figured it was valid, as tomorrow would be the first day of the new school year. In fact, Yamato was going to be starting his first year of high school, while Taichi would be starting his second. "What about it?"

Yamato didn't know whether Taichi was genuinely trying to have a decent conversation with him, or whether he was humouring himself. He wasn't used to holding conversations with his brothers, as they often kept him out of their discussions.

"Just . . . worried, I guess. About starting a new school . . ." Yamato trailed off. It was true, but he excluded his main thoughts – that he had actually been thinking about how much he wished he wasn't going to the same high school as Taichi and Eito, and how much they were going to no doubt torture him during school hours with their friends on top of what he endured at home.

"Oh," Taichi replied, looking bored. His attention then turned to the front hallway as a sound of a lock, and subsequently the front door opening and closing, were heard. A few seconds later Toru came into their view.

"Hey Taichi," Toru greeted, ignoring Yamato's presence.

"Hey," Taichi replied, flicking his eyes to what he hoped was boxes of pizza in Toru's arms. "Pizza?"

"Yeah," Toru confirmed. "To celebrate the start of another year of college. For me. And high school, for you and Eito. I guess."

"Thanks for the enthusiasm," Taichi replied dryly.

Toru grinned, then frowned as he glanced at Yamato. "Get off the couch," he ordered, eyes narrowed.

Yamato quickly did as told and sat on the living room floor. He disliked how they always tried to make him feel like he was doing something wrong – it wasn't like there was a written rule that he wasn't allowed to sit on the couch. Sometimes he would be sitting there without Toru or anyone else saying anything, and other times – like now – they said something. He disliked how their rules changed based on their moods.

"Did Hideki or Eito fuck you today?" Toru asked casually, as if it were a normal everyday question. Then he added with a snigger, "I know Taichi hasn't."

Taichi gave Toru the finger as the elder smirked back. Yamato shook his head lightly, hoping Toru wasn't going to rape him because of his negative answer.

"Hmm," Toru pondered slowly, studying Yamato's face, who had his head lowered so as not to look him in the eye. Toru smiled as he thought of an idea. "Go get the biggest vibrator. And some sticky tape."

Yamato's hopes died as he got up and slowly headed to Hideki's room to retrieve a vibrator twelve inches in length and five inches in circumference. He grabbed a roll of sticky tape, and a small tube of lube as well, before returning to the living room.

"Take your time," Toru said sarcastically, then looked at the KY Jelly in Yamato's left hand. He raised an eyebrow. "I don't think I said to bring any lube. Did I, Taichi?"

"Nope," Taichi replied, looking half-bored and half-amused.

"W-well, I figured . . ." Yamato stuttered in a tiny voice. Toru always managed to intimidate him just by being there – Hideki had an even worse effect on him.

Toru slapped Yamato hard and sharp, surprising him and making him drop the sticky tape and lube onto the floor. Yamato's right hand instinctively gripped the vibrator tighter, afraid it would fall too, especially if Toru decided to hit him again.

"Don't think for yourself, moron. We think for you." Toru glared at him, then shifted his gaze to Taichi. "You wanna insert it?"

Taichi shrugged. "But it's your area of expertise . . ." Truth be told though, he didn't really want to . . .

"Come on," Toru pressed, smirking. "You've never even inserted your own penis, at least insert this, eh?"

Not wanting to seem soft in front of Toru, Taichi rolled his eyes and held his hand out towards Yamato. "Fine. Give it here." Yamato handed him the vibrator. "I turn it on after, yeah?" he asked Toru, who nodded. "OK. So . . ."

"Pull your pants down and get flat on the floor," Toru barked at Yamato, who did as told, releasing his lower confines and laying face down on the floor obediently.

Toru then sat down on Yamato's back, facing Taichi who was on his knees before Yamato's buttocks. Toru spread Yamato's arse cheeks apart, making the puckered hole of his anus more visible to Taichi.

"It's not gonna go in easily without lube," Toru told Taichi. "But it should be fine. Just ram it in there real hard – don't worry about him."

Toru and Taichi exchanged chuckles as Yamato squeezed his eyes shut, awaiting penetration. Taichi pressed the tip of the vibrator – sculptured like a penis – into Yamato's arse, and felt resistance right away.

"Just keep pushing," Toru urged as Taichi seemed to be struggling to push more in. "There's ten inches left. Come on."

Yamato's anus was so tiny, Taichi observed. It looked so microscopic compared to the large vibrator in his hand – could it really fit? Then again, he had been awed whenever he had watched Hideki, Toru or Eito shove their eight inch cocks completely inside Yamato with relative ease.

Taichi grunted lightly as the head of the vibrator disappeared inside with a strong push. Yamato made some kind of strangled noise, obviously trying to hold back on yelling.

"That's it, since the head's inside it should be easier getting the rest all the way in," Toru smirked. "Especially considering how many times we've broken him in." He laughed, receiving a grin and a nod from Taichi.

Taichi pushed further inside, noticing that Yamato's anus was bleeding, but Toru didn't seem to care, so he didn't say anything. He kept shoving, prodding and twisting the vibrator's way deeper inside, receiving different noises from Yamato.

At last all twelve inches disappeared, and Yamato lay their whimpering with his eyes still closed.

"Well done," Toru clapped Taichi on the shoulder, before grabbing the roll of sticky tape and began securing the vibrator with it, adding to Yamato's discomfort. Yamato didn't even think the tape was needed, for he was sure the vibrator wasn't at risk of falling out, what with being as big and wedged up so far . . .

Toru then got off Yamato and flipped him over, grabbing Yamato's penis and pressing it against the inside of his right thigh, sticky taping them together, supposedly to stop Yamato from gaining an erection or properly relieving himself.

"You can turn the vibrator on now," Toru grinned at Taichi.

Taichi placed his hand at the bottom of the vibrator and pressed the switch on as directed, causing Yamato to jump slightly, making them laugh.

Another sound of the lock and front door opening and closing, and Hideki and Eito had come home, making their way into the living room.

"What . . .?" Eito questioned with a smirk on his face as he saw Yamato on the floor with sticky tape covering his penis and buttocks area.

"Vibrator," Toru answered, mirroring Eito's smirk.

Hideki observed their handiwork with a raised eyebrow, commenting, "What a waste of tape."

The brothers laughed amongst themselves, as Yamato struggled to keep calm from the constant vibrating movement in his lower body.

"OK," Toru pulled Yamato's pants up, before standing up himself. "If you behave we'll take it out tomorrow morning. If you don't . . . you can go to school with that thing buzzing inside you. But then, you'd enjoy that, no?"

Laughter ensued as Yamato got onto his feet awkwardly, trying to center his mind off thinking about the vibrator working inside him. He waited for commands with his head lowered.

"Has he cooked dinner yet?" Hideki queried Toru and Taichi, indicating Yamato.

"No," Taichi replied. "But Toru bought pizza. Do we still need him to cook dinner?" Taichi didn't know whether he was just asking a simple question, or trying to help Yamato out with his duties . . .

Eito sniggered, "If we let him cook with a vibrator up his arse he'd probably sperm all over our dinner." The other boys laughed.

"OK," Hideki decided, "Yamato, you're not cooking dinner tonight, so you can forget about having dinner as well. Get lost."

Yamato nodded, avoiding eye contact as per usual, and left to his room that he shared with Taichi. After their father had died Hideki had gotten rid of Yamato's bed, so now he slept on a thin mattress on the ground, with a stuffed animal as his pillow. He also had a cardboard box in the corner of the room where he kept all his clothes – hand-me-downs from his older brothers. Hideki rarely bought him something new.

Yamato closed the door behind him gently, leaving it unlocked as he wasn't allowed to lock it unless one of his brothers, usually Taichi, was in there with him. He went straight to his mattress that he had long since outgrown in size, laying face down as that was the most comfortable position, considering what was up his backside.

He sighed sadly, tears threatening to fall from his eyes – he hated that. He hated how he seemed to cry so easily, how it never took more than a few words from his brothers to crush him emotionally, how he still depended on his brothers regardless –

And he couldn't ignore the vibrator. It was starting to feel good. He moaned softly, his right hand unconsciously going down towards his penis to caress it – only to feel the undesired surface of sticky tape. He groaned, both frustrated and ashamed that the vibrator Taichi had lodged up his arse was making him hard.

He looked at the door. Taichi would be a while eating pizza, wouldn't he? He could turn the vibrator off until Taichi came in, and turn it back on before Taichi noticed it had been off . . . right? He stared harder at the unlocked door, as if it had the answers.

Clenching his fists in sexual frustration, he decided he'd risk it. The vibrator was making him feel so hot, and as it was so large, making his stomach feel like lead, as if something huge had ploughed into him; though he guessed that was what had happened . . .

He reached down and turned the vibrator off. The soft buzzing stopped, and he waited with baited breath, as though his brothers would notice that the vibrator was no longer emitting any sounds from rooms away.

Nothing.

He relaxed a little, but knew he had to keep his ears focussed on the door for any sounds of Taichi's footsteps approaching. He was less eager to turn the vibrator back on now that it was off, but he knew he had to for the night before Taichi came back. He only hoped he'd manage to drift into a deep sleep, and hardly notice the thing.

Apparently he had thought too much of sleep. Staring at the door for what seemed like hours had made him bored and tired, and he had slowly drifted off. But he awoke with a start as Taichi shook his shoulders.

"Taichi . . .!" he exclaimed, alarmed.

Taichi nodded, then beckoned at Yamato's lower body. "Is it off?"

It was an unneeded question, for they both knew the answer. But as Taichi had posed it, Yamato felt forced to voice an answer.

"Yes . . ." he replied, barely above a whisper. He lowered his eyes and waited for Taichi's reaction, be it verbal or physical – or both.

Taichi stared at him silently for a while, before finally stating, "You must've accidentally switched it off from tossing and turning so much in your sleep." And with that he had gone to his own bed, his back facing Yamato.

Yamato was frozen. Was Taichi being serious? No, his brother had known he had turned it off himself . . . right? But then why did he say it must've been an accident? Surely he wasn't making up an excuse . . . for him? It seemed like it . . . but that made absolutely no sense. Yamato had to be sure.

"Taichi . . .?" he spoke through the darkness, looking at his brother's silhouette. Taichi didn't respond, which would usually deter him, but not this time. "Taichi?" he repeated.

It took a long silence, but Taichi finally grunted in response.

Yamato took a deep breath. "Did you want me to turn it back on . . .?"

Back to silence.

And then, ever so slowly, Taichi pulled his covers up over his head, and burrowed himself closer towards the wall, and further away from Yamato.

He was ignoring Yamato's question.

It was hard to tell who was more surprised and confused – Yamato, or Taichi?

End of Chapter

. . . If you've made it this far, congrats! I've had to use this first chapter to set the background, so it was slow at the start . . . and I lost momentum as it went on, so excuse the ending. But the fun bits should be in the next chapters! (Note: My definition of fun may not be the same as yours.) Yamato meets Ken, and Taichi's all confused about whether he should hate Yamato or not, leading to him being nice to Yamato one minute, and mean to him the next. Ooh. Cough.

Review, please?
