Summary: Byakuya knows the trust that those eyes demand is not warranted, but he simply cannot break the spell that they have on him.

---

Aizen-sensei was a difficult man to read.

It wasn't that he explained anything overtly difficult or that he went out of his way to confuse him, but his personality... it was something he couldn't grasp even though he'd tried very hard. He considered it a failure on his part for not finding the source of his confusion because, as the sole heir to the Kuchiki Clan's great legacy, it was his job to search through the lies for that little truth that preserved honor.

Still, in Aizen-sensei's presence, there was sense of tranquility and a trust that he struggled with. A person that was difficult to read usually meant doubt and Byakuya could safely say that it left an uncomfortable feeling in the pit of his stomach because he hadn't bothered to question it. It was a fact that was simply accepted, like one might with a close friend or family member. Byakuya couldn't say that trust was well- or ill-placed, but he knew that it wasn't right to place it so haphazardly.

He glanced up from his work to the front of the class room, listening to the lecture being given and the soft giggles of the girls from across the class, as restrained he supposed giddy school girls could be. He didn't really know what constituted as handsome and he never really cared. It wasn't Aizen's kind, 'nerdy' look that he admired, but his proficiency at maintaining a classroom full of giggling girls and his beautiful calligraphy. Aizen-sensei was a man who deserved respect for his talents, not for some new fetish spreading around.

The characters on the board were simple and Byakuya had no issues imitating that hand, careful and precise, but not in the realm of hesitation. Most of those who joined these lectures in their free time only did so to witness Sousuke Aizen up close and personal. Talentless idiots who were so worried about what he'd think of their hair rather than their work.

But to his astonishment, Aizen-sensei never complained. He never scolded. He told them they just needed practice, that he'd make more appearances and they should come and join him again, that they had no reason to be down because no one was perfect on their first try. He was much more patient than Byakuya would ever be...

"Perfect as always, Kuchiki-san," Aizen-senseii's soothing voice sounded in his ear.

Byakuya was never a nervous wreck, but something about him being so close, without his knowledge, sent a shiver down his spine that was almost enough to make him drop his brush. This was a person he trusted? Someone who could sneak up on him without a moment's hesitation and kill him if he so desired? But the Kuchiki heir didn't question it and grinned a bit more proudly than he intended. "Thank you, Aizen-sensei."

It wasn't a problem that he wasn't regarded with importance. Byakuya attended the academy solely to prove that he didn't need his heritage to make it into the Gotei 13, that he could surpass his fellow students with his hard work, not a title and a bit of favored treatment because he was a noble. Aizen-sensei had never gone against his wish to be treated like any other student like most teachers had. He pointed out flaws when he saw them and assured him that everyone had troubles and with his talent, he could master it without too much trouble. Byakuya didn't have to be special in these optional lectures... he just had to be himself--a kid aching to learn and grow.

Aizen-sensei gave him that gentle smile and moved onto the next and so, Byakuya went back to the characters on the board, concentrating solely on it rather than those jealous stares on his back. He wasn't there to make friends. He was there to enjoy his hobby of Calligraphy and if it just so happened that Aizen-sensei liked his better than theirs, then so be it.

The lecture finalized with a quick reminder that Aizen-sensei wouldn't be available for a few weeks due to some training in his division he needed to be a part of and to keep an eye out for a notice, but Byakuya didn't pay much mind to it. There had been no need--there was always Calligraphy club he could try and sneak in on. He gathered his things quietly as other students shuffled out around him, trying to decide what to do with his free time. Callirgraphy and training were nice and he strived to be perfect in any form, but maybe a bath would have been nice...

"Kuchiki-san, would you mind staying behind for a little bit?"

Byakuya glanced towards Aizen-sensei, a little confused, but gave a curt nod and finished gathering his things, waiting for the last of the lingering students to file out, disappointed, perhaps, because they weren't asked to stay behind. It wasn't as if Byakuya liked school so much that he stayed behind in classes unless it was necessary...

When the last girl was reluctantly escorted out and the door shut behind her, Aizen-sensei made his way back to his desk and Byakuya was right behind him. "Is something wrong, Aizen-sensei?"

"No, of course not, Byakuya." The noble heir didn't flinch as he normally might have from such blatant disrespect regarding his station. A teacher was a lot different than a silly woman who gave nicknames and he could still hear the polite tone. Nothing ill was meant and thus, he let it slide by without a word of complaint. "I was thinking about compiling the works of my best students and publishing them. I'm sure you've seen the journalistic views of Seireitei in your household. It would be an honor if I were to be given permission to include yours."

Pride swelled within again and Byakuya did his best to make sure the satisfied grin on his face was less haughty and more of a respectful and appreciative one. "Really?"

Aizen-sensei smiled and Byakuya was not going to lie. Sousuke Aizen had a nice smile, one much like Captain Unohana's, that made a warm feeling banish that uneasy one in his stomach. He couldn't remember the last time he had received such a thing that held no remorse, no fear, but familiarity. "Of course. Very few within the Gotei 13 show as much promise in the art of Calligraphy as you do. Would you be willing to submit something?"

"Of course!" He answered, perhaps a little more quickly than he intended, worked on reigning in that enthusiasm and did his best to hide it like Grandfather Ginrei may have done. "Yes. When will you need it by?"

"Oh, by the next lecture is fine. If you have something before then, you may give it to your grandfather. I'm sure he'd be willing to send it over to fifth division."

Burdening Grandfather wouldn't do. If it was important, he'd do it himself, but a few weeks was enough time to work on some more complicated characters that didn't seem quite perfect just yet. The harder it was, the better it'd be when it finally came out. "I will be sure to have it by then, sensei."

He wasn't sure when it happened, since Byakuya was never so wrapped up in his thoughts that he missed any sign of movement, but Aizen-sensei had gotten inexplicably close in those few moments he wondered what he'd be submitting. Or maybe he had been steadily approaching the whole time and his level of trust betrayed him, left him open for yet another one of those potentially dangerous things. Anyone could be an enemy, Grandfather had told him. Anyone, even those you may trust the most, could rip you apart within seconds if you aren't careful. Byakuya took a step back, grin fading just a little as sensei took another forward.

His gentle smile was still there, his brown eyes still so very open and kind... Byakuya couldn't see any ill will within, though he knew it wasn't right to be caught so off-guard by someone who worked in the Gotei 13.

Long fingers reached out, brushed across his cheek softly, like the brush of wind--there, but almost impossible to detect. "Is something the matter, Byakuya? You look almost... frightened."

"No, of course not," he replied stubbornly, standing his ground though he averted his eyes from the ones just begging for his trust. It was as if it were some sort of spell, impossible to resist if one stared long enough into those chocolate eyes. "I... should be going."

"There is one more thing I wished to ask of you, but if you must be going..."

Byakuya couldn't resist. He was compelled to seek out those eyes and the slight disappointment reflected there was enough to make him cease all thoughts. Disappointment was the last thing he wanted to see from anyone he respected enough not to bear a grudge against. He hated to see it in Grandfather's eyes, he hated to see it in any of his teachers and, even though it was optional, he regarded Aizen-sensei in the same light. "What is it? I can spare a moment longer..."

He almost wished he hadn't said it, ignored that strange compulsion to simply believe in Aizen-sensei's soft voice and kind demeanor and run from the classroom, with or without his tools. He'd buy more--they weren't that important.

Before he knew it, his back had found the wall and sensei was no further away than when he started his retreat. If anything, he was closer. He had never realized how grown-ups like Aizen towered over him or how warm it was starting to feel trapped between his favorite Calligraphy lecturer and the wall. Aizen-sensei's expression was still kind and understanding, his lips up in what seemed to be a perpetual smile of benevolence. The hand on his cheek remained, incredibly warm and so much bigger, stronger than his attendants, even his grandfather. So much bigger than his own. He never allowed any touch that was unnecessary--there was something about his space being invaded that put him on high alert, that reminded him that many people could have many uses for the heir to one of the four great clans.

"Aizen-sensei..." He said with no inflection, as little emotion as possible, but was certain his message got through loud and clear. He had been warned about the people outside of the household and that if he was not prepared, that he could easily be taken advantage of. He'd never thought that the polite and trustworthy man before him was the type. He'd never get away with it... the full extent of Seireitei's law would be brought down upon any transgressor--as worthy bait he was to bring the clan to its knees, he was certain that whatever Aizen may have gotten from it was not worth his death.

But Aizen didn't move, away or any closer. He seemed to regard him, but remained silent, as if he was trying to think over the consequences of not heeding to the heir's apparent threat.

"If you have nothing to say to me--"

"Do you trust me?"

Panic and irritation made way for surprise and though he'd worked hard on schooling his expression to please the household, he couldn't do it quite as well as he hoped. "Why would you ask such a question?" He countered instead. No matter what, he did still have some semblance of trust because, if he had wanted to, he could have easily struck him, killed him, whatever it was that people did with little heirs. Aizen-sensei had only invaded his space with the same affectionate smile on his face.

"Have I shaken your trust in me, Byakuya?"

The noble heir shook his head slightly, defiantly. "No. My confidence cannot be shaken so easily. I'm just..."

"Has no one held you? Embraced you? A young boy with your duties must seek release somehow."

Byakuya tensed at the uncomfortable shift in the conversation. He didn't... need those things. Didn't need silly things like physical contact because those didn't make a strong leader. Maybe it was kinda nice when Yoruichi stepped out of her boundaries and did what she liked, no matter how badly he reacted to it. So what was sensei even trying to get at? "Calligraphy is enough, sensei," he replied coolly, much more than he intended."Is this... what you wanted to talk about?"

"It's unhealthy to leave things like this repressed for too long." Aizen-sensei kneeled down and Byakuya had no where to turn, forced to gaze into those eyes that just demanded trust, a hint of sympathy and something much heavier, thicker... darker, even, lurked within. He'd never seen it before and couldn't describe any clearer than that, but it sent an unpleasant shiver through every fiber of his being when his Calligraphy lecturer leaned in closer and pressed his lips so very gently to his open cheek. "It's all right to trust people. It's not a sin to let yourself go."

"Sensei..." Byakuya wanted a little distance, that bubble of protective space that was his, that helped spare him from those unpleasant things in the world. He loved his cushion, his lack of social skills, his lack of desire for the company of those he deemed unworthy because it meant there could be nothing to shake his confidence, nothing to embarrass him or his family name... nothing to disappoint.

But his sensei's free hand grasped the sash about his waist and his hakama with gentle little strokes, as if musing what they'd do next. He squirmed, finally willing his hands to press on the shoulders of the man before him, looking away from those manipulative eyes. "I'd like to go now, sensei, if I'm not needed."

There was no hesitation, no fear, but he knew that it was a front. He wasn't quite sure how he'd managed to keep his voice so steady, and he was sure it would not last unless he got away. This wasn't orthodox behavior. He was pretty sure that no teacher was supposed to do this with a student.

"It's all right to be a little afraid, but if you trust me, you know I won't hurt you."

"This isn't... about trust. Remove yourself. I won't ask again!"

The more he spoke, the more obvious it was becoming to himself that he was feeling something. That anxious knot twisted tighter and tighter each moment he allowed this invasion of space to continue. His trust had dwindled, his need to get away from such an uncomfortable moment doubled and yet... he was pretty sure he had more strength in him to push away the passive man in front of him.

"It's normal to be fearful of what you don't understand."

"I..." Gingerly, the knot in his sash was undone and his fingers curled in the haori of his sensei. "I"m not afraid! I just don't think it's appropriate!"

Aizen smiled innocently and pressed another little kiss to his cheek. Something a father or mother might do, something slow enough to leave a reminder, but chaste enough that it left no hidden agenda. "Actions speak louder than words, Byakuya-kun."

He was right... he could yell until he was hoarse, but it wouldn't make a difference if he didn't put any force behind it. A lesson, perhaps? A test he was being given? Would the House really go so far as to push him into such a situation, to bring an outsider who could turn the tables on them and could really do harm... it was impossible. They weren't irresponsible. But what could Aizen-sensei possibly get out of this...?

The cheap fabric was slowly pulled away, his fists curling tighter, reminding himself that it would be so very easy to get himself out of this unpleasant situation with a simple push. Aizen-sensei wasn't trying to hold him there. He was on unsteady ground, moving slowly, reminding him that he had a choice.

It's all right to be a little afraid, but if you trust me, you know I won't hurt you.

But... what could he want? If he wasn't trying to hurt or humiliate him, what could he possibly want? "Sensei..."

Aizen's hands trailed down his thighs, following the path of his hakama. He never noticed the one on his cheek had disappeared. "You want to ask 'why', is that right?" Just as liesurely as they moved downward, they moved back up to rest gently on his hips. "It isn't to punish you or to humiliate you. It must be incredibly difficult for a boy to grow up with the weight of a family on his shoulders. No one to play with, no one to question you... no one to show you the wonders of the body."

Byakuya had never been interested in things like 'wonders of the body' because that just didn't seem important in the grand scheme of becoming the Head of his Clan and he wasn't sure a demonstration in the middle of a class room where he came often was his ideal place to start such an exploration.

Apparently, when he didn't reply, his sensei took it as 'go right ahead' and as those warm fingers grasped a special area he'd never grasped himself, his hips bucked in surprise and the air was shocked from his lungs. His cheeks burned with embarrassment at the soft chuckle from Sensei and he put a little more resolve in trying to squirm away. "Sen-Sensei... this isn't..."

"Did it surprise you?"

He did his best to hide his scowl. How could he be so amused about something like this? And mocking him, too! Very few had ever done so to his face--Yoruichi and the Shiba clan had been the few who'd ever approached him in a less than formal manner. He'd been embraced by Yoruichi and punched 'playfully' by Kukkaku, but he'd never been touched like this before. He'd never been so... vulnerable.

But Aizen-sensei's eyes glittered with that look that said he meant no harm and in spite of himself, in everything he knew to be wrong about it, he did nothing to push him away. Once it was over, he'd never speak of it again, never worry about it. He'd go back to their student/teacher relationship and that would be the end of it. He had never done it himself, but there had been times when his resolve would waver and he was more than tempted to do so. Yoruichi had once told him it was a natural thing, but anything Yoruichi said was never taken seriously. Her nature was perversion and he wanted no part of it.

But if he wasn't commiting that perversion himself... it didn't taint his hands, was that not right? He shuddered as the hand grasped softly but firmly around him and moved carefully, an agonizingly slow rythym that set his blood on fire within mere seconds.

It seemed so terrible, such a dirty deed, something that one needn't have any knowledge about until it became necessary later on when choosing a wife. His skin prickled with shame as the twisting feeling swirled with the fire, the knot in his stomach no longer an unpleasant anxiety but a fire that hurt and burned, and yet felt so nice.

But Aizen-sensei looked at him with nothing but some sort of understanding he didn't think belonged, a glitter in his eye that forced him to swallow a whimper around the pants he was having trouble repressing. He didn't dare look down, didn't dare seek out the perversion going on below his waist. If he bothered to accept the fact it was going on, he probably would shove his teacher away and dart off, left to wonder and repress these inexplicable feelings racing through his blood at that very moment.

The fire danced and glowed brighter. Beneath the flesh his blood was pumping, heart racing to keep up with his mind as everything from how wrong it was to how amazing it felt, and as it flowed harshly through every vein in his system, it burned. On the outside, goosebumps had attacked, as if he were in some sort of freezing atmosphere.

He glanced toward the doorway, trying to figure out how long he'd been standing there, pride refusing to allow his legs to tremble, no matter how much their muscles wished to. No one had come in to drag Aizen away and no one had come searching for him. Every second he stood there with his pants down was another second that could have gotten them caught.

... and Sousuke Aizen didn't seem to have much of a care for that. The pace was driving Byakuya mad and all he could do was take deep breaths so as not to throw all his pride away and thrust into that big, inviting hand grasped around his slender cock.

He was faintly aware of the other hand trailing over the insides of his thighs, dragging more involuntary shivers from him. His head swam, like it might if he were in a room with burning incense for too long. His heart pounded mercilessly at the embarrassment he might have suffered if someone should walk in, at himself for being so weak and the glorious feeling he was certain he'd never allow himself to experience again. Emotions... emotions were worthless and as this was such a private act, it was also something unnecessary.

He closed his eyes and bowed his head, the hand caressing his inner thighs disappearing completely and the hand groping stopped its strokes, though those fingers tapped one after the other, like an undulating snake. "You're a very pretty boy, Byakuya-kun."

He grit his teeth in annoyance. "Don't insult me. Assaulting my person is one thing... that is no fault but my own, but don't you attempt to trample my pride!"

Aizen chuckled softly, a merry sound that he made him realize he was under a spell when his knees went to buckle. "I meant no such thing. I wouldn't lie to you. Perhaps you'd care for 'handsome' then?" Fingers pressed gently to his lips and he looked hesitantly, staring into those eyes that had trapped him from the moment their gazes locked. The pit of his stomach continued to emit that painful fire, so tightly wound that he was certain he'd explode any moment. "Go ahead. Do as your instincts tell you."

By all rights, if he listened to his instincts, he would have aimed a Byakurai right between the brunette's eyes. There was nothing telling him to stay there and suffer this humiliation but a dark voice that was nothing like the one who sought him out in his dreams. It was a sinful one, the one that usually told him to break his resolve and commit such horrible acts upon himself. Resisting it had become so difficult and as it sighed in pleasure when he gave into it's calls, it seemed as if one burden had been lifted and another had been put in its place.

"You must not..." He ground his teeth, swallowing his pride. "You must not utter a word of this to ojisama..."

Aizen's expression changed slightly to reflect surprise, he supposed. Byakuya hadn't gauged whether it was a good or bad reaction. It really didn't matter, as long as the Head of the family didn't hear a word of his disgrace to the Kuchiki name for allowing himself to be pinned so easily, brought to such a miserable state. It would ruin all the respect he'd worked so hard to get all these years if a word was breathed. He still placed so much trust in Aizen, even though anyone else may have found it a terrible decision, but a part of him enjoyed the attention, this 'lesson' of sorts had been the most affection he'd received in a long time.

"Of course not. I see no reason why he would need to know."

That smile again and those lingering fingers... he was aware of the flush that creeped into his cheeks at the situation, that warm smile that caused butterflies to flutter in his stomach and as his instincts dictated, he wrapped his lips around the intrusive digits, eyes never wavering from the gentle brown in front of him. Aizen's expression never changed, but he was faintly aware that there was something churning in his mind as Byakuya's tongue made hesitant strokes on those fingers as sweet as the man's smile.

"You really do learn quickly, don't you?" Aizen mused softly, scooting in just a bit closer than Byakuya had anticipated. "Your ojisama is very keen to point out your faults, but I can see he's very wrong about you."

His... faults? His hands curled tight in the fabric of Aizen's haori again, suckling gently on those fingers, his reason far beyond what he could comprehend. Grandfather Genrei was supposed to be critical, but to everyone, even those outside the household? It wasn't a stretch. He expected he hadn't met with his grandfather's expectations and it didn't seem at all wrong he might criticize him to others or in front of others. It only meant that he had to improve in every aspect of his life, whatever it may have been.

So distracted with the fingers in his mouth, he'd forgotten the ones wrapped around him as they began their careful strokes again and his pride was no match for the moan that slipped through. He wasn't quite sure how, but his cheeks were hot with more than the rush of adrenaline as Aizen pulled his fingers away, his lips twitching just enough to catch Byakuya's attention.

"A delectable sound, Byakuya -kun."

He really wished he would stop calling him that and he'd do more than those simple touches that weren't enough (even though he was so close), so the humiliation would be over, but just as he went to complain, that hand wrapped tight around him, painfully so as the fingers the teen was sure he spent most of the time licking and sucking moved down to caress a particular orifice of his body he was sure nothing was to go in.

He moved to pull away, deciding that he'd lowered himself enough, that no feeling was worth that perversion and that the trust he had in Sousuke Aizen shattered in that moment. Hiding seemed to be the best course of action, the only way to make up for his lapse in judgment. Aizen leaned forward, that sickeningly sweet smile never disappearing, as he leaned up and brushed his lips over his cheek again. That feeling of parental guidance returned and for a split second, his defenses fell and that intrusive finger slipped through. "If you don't relax, it'll be more uncomfortable for you," he chided gently, as if scolding some child for running in the house.

"This is going to far...!" He countered stubbornly, trying to find that ledge where his pride was stable enough to banish those pooling feelings of anxiety and hot, painful pleasure circulating below. It collapsed as soon as he got a foothold and that finger sank deeper, wriggling, much to his displeasure, for something... "Aizen, I can't allow--"

Something, as if a button had been pushed, clicked inside and he, for once, stopped thinking entirely, his cry of surprise, pleasure, it didn't matter what it was, but it certainly felt very, very nice. His nails scratched at the cloth covering the powerful shoulders in front of him, his legs trembled and if it weren't for that restraining hand, Byakuya was quite sure he would have lost himself completely.

Somewhere in his mind, he was aware of his lips moving, his hips twitching insistently, but his pride had long since shut down and he didn't bother to scramble for it. He wanted it over, not for the humiliation he'd suffer, but for some sense of completion that he knew would come once it was.

He wasn't aware of Aizen's smile any longer, or that feeling of losing control. He didn't care if anyone walked in, or if the Head of the Clan found out. He didn't care that he had a sense of falling, that his chest actually burned from his shallow breaths, that it was certainly inappropriate to be finding something attractive enough about his teacher, someone he looked up to, to feel this way. All that mattered were those hands working against each other, giving him no reprieve from the aches and the need burning inside. The acts of sex... how much different would it feel if Aizen's hand were something else... something slicker, tighter, something that would moan like a wanton whore? Or the fingers (he was aware that another had slipped in without his consent, but couldn't find the will to care) inside, knowing where that spot was, but avoiding it? If it were something bigger sinking in, something filling, something offering a connection he had never had before--

Again that button clicked, once, twice and Byakuya's heart stopped. His hips jerked into that big, warm hand, against those fingers, hands grabbing desperately at the suddenly comforting presence of the man who had spent these past moments molesting him in a classroom.

That white flash, the spark of pleasure reaching its peak and as suddenly as it happened, it faded away. He was aware of his erratic breathing, of the man holding him on his shaky legs, those hands pulling away and that cursed grin that he wanted to blame for everything and yet nothing at the same time.

He sank to the floor, guided by a single hand he wanted to push away, but had no will to. He shuddered to think how horrifying it would be if it ever got out and how incredibly vulnerable he must have looked, but the only thing he could do was grope blindly, eyes glazed and unfocused, for the hakama he was sitting on.

Aizen's shadow appeared and left before it returned again with a warm, wet cloth that skated over his face, leaving behind a cooling trail that his body eagerly greeted before it sank lower, touching still very sensitized skin and eliciting a slight gasp. He glanced up, fully intent on shoving him away, reminding him of his place and whatever else he could think of when he caught the soothing, caring look and a tongue darting out to lick one of the fingers covered in a white, creamy substance he could only guess was his release. "You are such a beautiful boy, Byakuya-kun. You even taste delectable."

The haze broke and he glanced away, cheeks burning... but from what? Was it flattery? Maybe it was embarrassment someone could say such a dirty thing and yet still sound so sincere and serious? "Aizen..."

He watched as Aizen wiped the remnants away and crouched down, giving him the little shove to right his appearance he needed, though all he wanted to do in that moment was sleep the last of his day away, in that very spot where he'd surrendered for a moment of pure bliss that he enjoyed and craved a little bit more than he probably should have. "Sensei," Byakuya started again, still content with his position on the floor. Though he had confidence in his ability to maintain a steady voice, the same could not be said for his legs at the moment.

"You want to know why?" The towel was tossed aside and Aizen's undivided attention was on him. That wiggling feeling in his stomach returned, something in him not wanting to see the look of appraisal after something so... wrong. "I wanted to show you that you're a boy with needs. There is nothing wrong with it. You can come to me anytime, Byakuya-kun. Wasn't it nice to let go, for just a little while?"

The young noble pursed his lips, turning away to hide another slight flush. It was nice. It was nice that he could do something without being looked down upon. It was nice to be simply Byakuya once in a while. "I had better be going."

"I won't keep you."

He climbed to his feet, checking their stability before pulling away from the wall and going back to gather his things before, after a final look and a weak grin of what he considered appreciation, he left the room. No one needed to know. He trusted Aizen to keep it to himself and he never intended to speak of his fall from grace.
