Chapter 1: Confusing Nights

"Hikaru, hello… Earth to Hikaru…" A determined, and slightly annoyed, Kaoru waved his hand in front of his brother's preoccupied face. 'He's been distracted a lot lately, what's going on with him? Why won't he tell me?' The barely elder twin had spent most of the evening staring out the large windows in his shared bedroom gazing at the gardens covering most of the grounds of the Hitachiin estate. It was not the first time the more easily sidetracked boy had wasted a whole evening daydreaming and it was starting to worry his mirror image. 'Sometimes I think it's worse when we're alone, like he's avoiding me for some reason. Does he know?'

"Oh, sorry Kaoru, what did you say?" Smiling at his younger brother the older sibling turned to face the homework he had all but forgotten in his unfocused state. 'What are you doing baka? Stop spacing out you're making him worry about you. Do you want him to start asking questions? FOCUS!'

Hikaru had been distracted more than usual for the last few months, but in the recent week he had begun to drift so far into his thoughts that even Kaoru's voice could not always reach him. The understandably concerned and mildly annoyed more sensitive twin was becoming genuinely concerned about his big brother.

'Are you sick?' –no

'Am I snoring again?' –no

'Is someone in class spreading rumors again?' –no

'Did mother threaten to disinherit us again for using her good dress form to pull that prank on Tono?' –no

Every time Kaoru tried to decipher the mystery of what had such a hold over his brother's preoccupied thoughts the results were the same. Hikaru would shake his head, shrug his shoulders and answer with a curt 'no'. In truth, it was really starting to get on the younger's nerves, but any irritation it might have caused was quickly outweighed by genuine concern for his beloved twin's wellbeing.

The very tolerant, but apprehensive teen tilted his head and stared at his mirror image. "What's wrong? You haven't heard a word I've said all day. You almost tripped down the stairs at school, you forgot the math homework you worked so hard on last night, and you even ignored Haruhi's invitation to cook you dinner… again. What IS it that has all of your attention lately?" Concern filled his eyes as he took his brother's hand and caressed it reassuringly. 'I can't say that I'm all that upset about him, ignoring Haruhi's invitations, but I know he has feelings for her, he always has, and now she seems to have them for him so why…'

Kaoru's thoughts were cut short by a sudden and unexpected, but completely welcome, hug from his clearly upset brother. "Please, I know you're worried about me, and part of me really DOES want to tell you what's going on but it's… complicated… and I just need some time to deal with it on my own first. It's not that I don't want your help or that I don't think I can trust you with it…" 'Far, far from it. You could actually solve the whole problem quite easily, but that is a truly BAD idea.' "… it's just… as soon as I have it figured out I promise I'll tell you, okay?" The pair just held each other in silence as the younger shook his head. 'I don't want to hurt you Kaoru and I can't lose you. I'll fix it and everything will be right again. You'll see, just be patient a little longer brother.'

"Ok, whatever you say. I'm going to go take a bath, here…" After pushing the homework he had completed only minutes ago across the shared table the more mature of the two stood and placed a hand on his troubled twin's shoulder. "… at least copy mine, so you don't get called out in class tomorrow, k?" Walking away without waiting for an answer Kaoru was relieved that he at least had a legitimate reason to bathe alone. 'It's just such a bad idea to have him in there with me. The mere thought of him… no shirt, no pants, naked, dripping wet, his skin so… NO. If I could come up with a non-suspicious reason to sleep in my old room, I think that might would be a good idea too. But if I did would I be able to sleep? Would he? What am I talking about; of course we can sleep without each other… right?'

Seeing the door close behind Kaoru's adorable backside singled that it was time to get down to business. 'Wait, when the hell did I start thinking of his ass as adorable?' Snapping himself out of his thoughts Hikaru once again shook his head and began to diligently scribble down his own version of the modern Japanese history homework being careful to reword the short answer responses. 'Can't have Sensei accusing us of cheating now can we.' Smiling at his own inside joke the busy teen overheard what he was sure was his brother's voice coming from the washroom. Both boys loved music and whenever one of them bathed alone, they would use their waterproof player to help them relax.

The soothing tones of some unknown Johann Sebastian Bach Aria wafted from the room along with... soft moaning? 'He's not… no… he's not in there doing THAT is he, with me right out here? Like I'm one to talk about self-pleasure in such close quarters, I'm glad he doesn't know about that.' The sounds of his twin's voice were soft and would have been undetectable to anyone else. Hikaru could easily discern that the younger boy was doing his best to not be heard but it was no good. The soft melody of the music could do nothing to mask the absolutely sinfully arousing noises he was emitting from the overly attuned ears of his other half.

The elder cautiously approached the closed door and rested his forehead on the cool wood. Closing his eyes, he listened wantonly to the delicious sounds of his brother's pleasure filled keening. 'Why am I doing this to myself? All I have to do is put on my headphones and pretend I never heard anything so why aren't I? Why am I just standing here picturing his… NO NO stop it! Don't think about his soft skin, or those mesmerizing lips, or how badly it turns you on when he…..' "GRRR" The completely frustrated doppelganger turned on his heel and went to his book-bag to retrieve his headphones. Putting them on and turning up the volume as loud as he could tolerate he tried his best to focus on homework. His hand now copied down the words without stopping to consider their meaning in an almost frantic attempt to block out any impure thoughts about his dear sibling. Concerns over accusations of plagiarism by their bitter and grumpy Sensei completely forgotten as ink met paper.

Within the washroom a very flushed redhead stroked himself gently but firmly as pictures of his brother flooded his mind. "Mmmm" In this rare alone time the younger of the Hitachiin boys had decided to give-in to his constant mental obsession with his twin and relieve his body of some of its tension. It was not the first time he had done it, but it was the first time knowing that the object of his fantasies has been just a few feet away in the other room. 'Oh, Hikaru! I wish this was your hand, or better yet your mouth. Why can't I get rid of these feelings? They just keep getting stronger, but I know they're wrong. I can never tell him, he can never know. But he can't REALY read my mind so a little fantasizing is safe, right?' His climax began to build as his mind formed pictures of his naked brother engulfing him whole and demanding his release. With one final firm tug he muddied his bath water with a sinful white cloud. Biting his lip, he stifled a load lust-filled moan as his world turned white with pleasure.

After cleaning both himself and the tub the youngest boy wrapped a towel around his waist and opened the door to his shared bedroom. He couldn't help but smile at the sight that greeted him. 'I wasn't in there that long, was I? Well, at least I know he didn't hear anything.' Walking over to his sleeping brother Kaoru turned off the music player and removed the headphones from his twin's ears.

Hikaru stirred at the sudden change and looked up at his sibling instantly blushing as a result of the dream that had just been interrupted. Shaking his head and standing to stretch the older teen quickly worked to draw attention away from himself. "Man, this was boring; I don't know how history could possibly be your favorite subject." Turning away from the desk he made his way to the washroom. "I'm gonna take a quick shower then we can go to bed." His copy nodded with a small smile as he closed the door behind him. 'Damn, why does he look so sexy when his hair is all wet like that?'

Never imagining the truth behind the situation he had walked into Kaoru organized the school papers and crawled into bed after drying his hair and donning a pair of baggy sleeping pants. Desperate to avoid his mind wandering into forbidden territory again, he reached for a book of Shakespearian plays and began reading. Twenty minutes later a clean and smiling Hikaru emerged from the washroom in a cloud of steam. The younger twin pretended not to notice as his nude sibling strutted across the room towards the wardrobe and dressed for bed. 'Damn it Kami-sama! Does he have any idea just how hot he is?' Quickly returning his eyes to the pages of the book he attempted to sound casual as he spoke to his now clothed older half. "Ready for bed?"

"Yeah, but you look like you're busy so should I go sleep in the other room?" Without knowing it both boy's had the exact same thought. 'That would probably be better, but neither one of us would actually sleep.'

'I took care of myself earlier so I should be able to sleep next to him without a problem shouldn't I? I don't want to sleep in this big bed all alone without his warmth next to me. I'm not ready yet.' Forcing a grin to his lips Kaoru took a calming breath before he addressed Hikaru. "No, that's ok. I'm not really into this right now anyway." Closing the book and placing it on the nightstand, he moved over making room for his brother in their king sized bed. "Come on, I'm getting tired and I know you are too. You couldn't even stay awake long enough to copy the homework." Giggling at his taunt the younger boy dodged the pillow thrown at his head with practiced precision.

"That's just because it's such a dull subject." After turning off the light Hikaru lifted the blanket and crawled in next to his adorable twin. The two siblings faced each other and intertwined their fingers like they had done every night since they were children. "Good night Kaoru."

"Goodnight Hikaru." Each closed their eyes and slowly their breathing became even and steady as sleep claimed them both. What had become a torturous and secrete nightly ritual between the two began not long after.

It was about an hour later that Hikaru woke up sweating and plagued by another nightmare so similar to the rest. Breathing heavily, he looked over at his sleeping brother to reassure himself that it was just a dream. 'That makes the fourth time this week. Maybe I should talk to him about them. No, I don't want to worry him… or worse. I can't lose him. Maybe Haruhi then. Yeah, she's a good listener and I bet she might even have some advice too. I bet I could talk to her before clubs tomorrow.' As the elder boy's thoughts drifted towards a hopeful solution to his own tormented thoughts the younger twin in the bed beside him began to show signs of his own tortuous dreams. However, Kaoru's dreams were less nightmare and more… wet.

"Hika… mmmm" The unconscious boy's voice was soft. It always was when he slept. The younger Hitachiin had no idea he talked in his sleep because his brother didn't dare tell him. It started about eighteen months ago when the twins started year three of senior high at Ouran. At first it was just sounds, rather evocative sounds, but simply sounds without words. After a few months the sounds became moans of obvious pleasure. Eventually recognizable words had slipped through the sleeping boy's lips. Most recently, in the last three months, was the addition of his older brother's name. At first Hikaru was confused by the noises coming from his twin and would often wake him just enough to force him to roll over and be quiet.

When the moaning started the older twin developed an unexpected and problematic response. One night his little brother was keening particularly loudly and when Hikaru went to rouse his twin and put an end to the odd musings he noticed that his body was reacting in a rather unexpected way. The first time it happened the confused boy just ignored the sensations and struggled back to sleep. After a week he made a conscious, but controversial decision to sit on the floor next to his large bed to 'dealt with the problem' as quietly as possible. He was extremely careful to not wake the unknowing source of the arousing sounds. It began happening often enough that the older boy started hiding a small towel and luxury hand lotion under his side of their shared bed.

The mental pictures that accompanied Hikaru's nightly ministrations became more detailed as Kaoru's unconscious utterances turned into words. Images of a forbidden familiar figure taking him in their hot mouth and stroking him with their skillful hands. He would never admit to himself the face in his fantasies until one night when everything changed. Nothing could have prepared him for what he heard that night three months ago. His name dripping from his twin's lips with all the lust he could never express in his conscious life. It was the single most provocative thing the unknowing boy could have possibly said. Without him knowing anything about his brother's self-relief to his soundtrack of arousing moans the younger was playing right into his elder sibling's deepest most secret desires. It had become more than just Kaoru's voice that ignited the lustful fire in Hikaru. It was Kaoru himself.

Whenever Hikaru would close his eyes and take hold of his hardened and needy member it was his brother's voice, his brother's face, his brother's touch that he pictured. He would never tell Kaoru, or anyone for that matter, that he had these thoughts and feelings, but when he heard his own name articulated by his brother's desirable mouth that night he nearly fainted. 'Wait, is he having these dreams about ME? All this time I figured it was Haruhi, but he's been having erotic dreams about me this whole time? Oh Kami-sama what does this mean? Is he in love with me? Am I in love with him? No, no, that's impossible. It's just because we spend so much time together. We just need to get a little distance and these feelings will go away. It's just hormones. It's not worth mentioning to Kaoru. I'll go sleep in his old room that way we can have some space and this will all blow over in a couple of days and he never needs to know. Right?'

Since that night the plagued older ginger had tried several times to sleep away from his brother only to fail each time. Either he would be utterly unable to fall asleep or he would wake up with Kaoru having joined him during the night. He had even gone as far as convincing his little brother that he snored so he wouldn't raise suspicions by sleeping alone. After a week he had given up on any attempt to sleep without his unknowing seducer only to start having nightmares. They were always basically the same and always terrifying.

Hikaru's Dream: The two boys were standing in the third music room where they used to have the Host Club. He would look to his brother, who was holding his hand and smile before saying "I love you." Just then one of the doors opened as Kaoru dropped his hand and started walking into the darkness outside the room. He turned and blew Hikaru a kiss just before dissolving into the black. Hikaru called to his brother and took off running, but there was only blackness. He never found his twin, and he always woke up in a cold sweat.

Rolling over and putting his feet onto the uncaring wood floor Hikaru turned his head to watch his twin's lips as he continued his unknowing seduction. "Kiss me… Mo… more Hika…" The older boy's cheeks turned an even deeper pink as he reached under his side of the mattress and retrieved what he needed to take care of the situation his brother was creating.

'Maybe it's better if I don't tell anyone. I should just try to be normal and get a girlfriend. But all the girls in our school are so flaky and annoying.' After a few timid strokes an idea struck him that he had never considered before. 'Why was Kao always trying to get me together with Haruhi when we first met her? Maybe he saw something I didn't. Would Haruhi even go out with me? I need to try SOMETHING; I can't just keep fantasizing about my twin… my brother… my Kaoru… mmm Kaoru…' His struggle to focus was lost as his mind swam with images of his other half in the shower, smiling seductively, the taste of his lips, the feel of his touch. "Mmmm… Kao…" He quickly slapped his unoccupied hand over his mouth to stop his voice from waking his sleeping sibling only three feet away. After a few more strokes his ministrations picked up in intensity and before long he was falling over the edge with pictures of his orange haired desire flooding his mind.

After cleaning himself with his secret towel the conflicted teen carefully crawled back into bed with a new found confidence stemming both from finding his release and deciding on how he would fix the delicate situation he found himself in. Feeling comfortable for the first time in months he reached out and encompassed his adorable little brother tightly in his arms as he buried his face in Kaoru's hair. 'He always smells so amazing. I know we use the same shampoo, but I never smell as good as he does. No… AHHH… stop thinking about him like that. He's just your twin, your other half. You don't want to kiss him. You don't want to touch him like that. You like Haruhi, you like Haruhi, you like Haruhi…' As if reciting a mantra Hikaru gradually found sleep chanting his 'solution' over and over in his head.
