Traitor -- Chapter 1

Ichimaru Gin let out a long, heavy sigh, running a hand through his silver hair. It had been a long day, and he was sore, tired, and coming down from a rather severe caffeine high, which all left him in a rather bitter mood. It also didn't help that it was nearing 3am…or rather, what would be 3am, if Hueco Mundo actually had a set time-zone. Gin was still basing his activities on the guidance of the watch he'd brought with him from Seireitei.

Finally, Gin reached his quarters, and with a soft sigh of relief, he entered. Stripping out of his soiled uniform, he collapsed on the Western-style bed, pulling the covers right up to his chin. Aizen had been quite rough with him tonight. Of course, Gin liked it rough, but tonight was taking it a little too far. Not that he would ever complain, though. No…he was not a fool, contrary to popular belief. He was here for a reason, and damn it all if he failed!

Feeling his mind begin to numb, Gin rolled onto his side and curled up, deciding it was time to sleep.

Flashback – About Three Months Earlier…

"Ano…could ya repeat tha', Yamamoto-taichou?" Trademark smile gone from his face, Gin openly stared at the leader of the Gotei 13, clearly hoping his ears had deceived him.

"I said, I want you to go with Aizen-taichou when he departs," Genryuusai-dono sighed, rubbing his brow. "He already trusts you. This way, we can have someone on the inside keeping an eye on him. You will do whatever it takes to stay on his good side, while learning as much as you can about his plans, and how he will carry them out. There will be a war, Ichimaru-taichou. And when the time comes, you will need to use the knowledge you've gained, and take him out…permanently."

"…Yes, Sir."

"Tell nobody about this meeting, Gin, or anything that we have discussed. No one may know except for us. All will be explained to the others when you finally return to us."

Ichimaru nodded solemnly, and left the room…

Gin awoke with a start, his face covered in sweat. Go figure, he would remember that day in his dreams. Seeing as he was alone, he let a deep scowl take over his face. He used to wish that the old man had sent someone else. But it wasn't long before he decided, that he was glad it had been him. Few of his friends back in Seireitei would have been able to handle the emotional and physical trauma that Gin endured on a daily basis. Deep down, he had always known he was the only one who could get the job done. But now….that didn't seem like it would be so easy anymore. Of course, Gin had known from the start that killing Aizen would be a difficult feat in itself. But he never expected his own emotions to get in the way of his mission. Now…now he wasn't sure if he could do it.

Heaving himself out of bed, the ex-taichou adorned his yukata, and left the safety of his room. The hall was dim, only slightly illuminated by the faux moon casting its light through the windows. Within a few minutes, Gin had reached the kitchen. He flicked on the light, and put on a pot of coffee. He wouldn't be able to fall back asleep, he knew, so there was no harm in filling himself up on caffeine. It would calm his nerves, at least. He didn't see how Aizen could stand to drink tea all the time. The stuff was gross.

Pouring the dark liquid into a cup, Ichimaru sat himself down in a chair. He sipped it absentmindedly, not caring that the substance burned the tip of his tongue. He needed to reorganize his thoughts, before things got even more out of hand than they already were. He was losing his resolve, and he couldn't allow it to diminish any further. It would only hurt him more in the end. He needed to reflect; remind himself of the reason he was here, of what he needed to do, and why he couldn't let his conviction falter. He was here to keep an eye on Aizen. He was here to gain information. And most importantly, he was here to kill the man, when the time came to finally put an end to this madness.

But despite knowing this, Gin had gone and fallen in love with the bastard. Maybe he really was a fool, after all, as everyone had always thought. Aizen treated him horribly, so why did he always feel so compelled to be near him? Sure, when they were around others, the man treated him with respect, and more like an equal than he treated anyone else. The others were all fooled, thinking that Gin was nothing more than an extremely loyal friend to their leader. But when no one else was around to see or hear, Gin was a slave. A slave to the bloodthirsty tyrant who showed him nothing but alternating feelings of extreme pleasure, and intense pain….and a slave to his own heart, which told him to follow this man to the ends of the earth and back, no matter how much suffering he himself must endure. Every night, Gin would be called to Aizen's private chambers, and the two would partake in…less than innocent activities. Sousuke loved to humiliate him, and though Gin would never admit it, they both relished in his pain. The silver-haired man still remembered the first time they had fucked; every detail of it. And while he had hated it then, he now wished things had stayed that way. That time, despite the obvious fact that it was rape, Aizen had been gentle; actually acting like he cared about him…

Flashback – First Night in Hueco Mundo…

With a heavy sigh, Gin raised a hand to knock softly on the door, forcing a typical carefree smile on his face. He had been called to Aizen's private rooms, and he instantly knew exactly what the older man wanted from him.

"Come in," came the deep voice of his Lord, and Gin could practically hear the smirk that he knew would adorn the man's face upon his arrival. Cautiously, he slid the door open, and walked in, pulling the door closed behind him without a sound.

"Ya called fer me, Aizen-sama?" He normally would have replied with a 'What can I do fer ya, this late at night?', but he didn't want to make this any more humiliating than it had to be.

"Come closer, Gin," Aizen beckoned him forward. The brunette was lounging on a sofa-like contraption; not quite a bed, but cushioned and blanketed all the same. Hoping his fear was undetectable, Gin walked forward with a calm air about him, and stopped only when he stood within an arms reach of the man.

"Do you know why I've called you here this late, Gin?" Aizen sat up straight and leaned forward, hooking a finger under his subordinate's chin to pull his face closer. Gin gulped, but kept his aloof smile in place.

"I can imagine, Aizen-sama," the silver-haired man stated simply, refusing to grace Aizen with a proper reaction. The ex-taichou smirked, and with a flourished movement, pulled Gin down into his lap. Ichimaru, who had not been expecting a move such as this, couldn't help but let out a soft gasp. The instant his lips had parted, Aizen crushed their mouths together, pushing his tongue deep into the cavern of the younger man's mouth. Gin let out a strangled groan as Sousuke flipped them over; now kneeling above him, legs on either side of his lithe waist, and hands pinning his wrists above his head. And still, their lips had remained sealed together.

Gin pulled at his wrists, testing the strength of Aizen's hold on him. There was no chance in all of Hueco Mundo he could break out of that grip. Sousuke flared his reiatsu, indicating his displeasure with even that small sign of resistance. Gin whimpered softly, and he could feel the older man smirk against his lips. Finally, just when the silver-haired male thought his lungs were about to burst, Aizen pulled away.

"Hmm…you taste even better than I'd imagined, Gin-chan."

Ichimaru raised an eyebrow at the feminine addition Aizen had placed on his name. "So ya've imagined how I taste, have ya?"

"Oh yes." The self-proclaimed King of Hueco Mundo grinned, and leant down to lick the shell of Gin's ear, eliciting another soft gasp from the younger man. "And not just your lips…but all of you."

"An' what if I dun want ya ta taste me?"

"What you want doesn't matter. I am the one in charge here, Gin. Do not forget that!" Aizen snapped, his eyes narrowing dangerously. "I have waited far too long for this opportunity. Now I finally have you right where I want you. You will do exactly as I say. You will not disobey me. You will not fight me. Every inch of skin on your body belongs to me, Gin. Is that clear?"

Gin shuddered, and nodded his head in resignation. Why fight it? There really was no point. Aizen was much stronger than he was, and even if that hadn't been the case, the brunette still had complete control over them all. He had no hopes of getting out of this unscathed, so he might as well try to make things as easy for himself as possible.

"Good boy…" Aizen smiled, obviously pleased with himself. "Now, if I let go of your wrists, will you stay still and behave yourself?"

Once again, Gin could do nothing but nod. Slowly, as if unsure of whether or not he could be trusted, Sousuke released the firm hold on his wrists. He waited a moment, but Gin continued to lay silent and compliant beneath him, so he moved on. Aizen's hands found their way to the zipper of Gin's coat, and ever so slowly, he began to pull it down, revealing the pale flesh underneath. Once the offending material was out of the way, Aizen ran his hands slowly over the exposed skin, admiring the smooth contours of Gin's body. Suddenly, and without warning, he pinched a nipple harshly, earning him a cry of surprise from his subordinate. Removing his hand, he leant down and took the small, hardened nub in his mouth, swirling his tongue around it, and sucking gently. Meanwhile, his hands moved down much lower, and swiftly untied Gin's hakama. Tugging the material down, he ran his fingers along the underside of Gin's length.

Gin arched his back and cried out sharply. The sensations - however minute - were too much for him. Sure, he'd touched himself before, but he'd never had a real sexual encounter. There was a huge gap between what could be accomplished by the two.

"Hmm…you're quite vocal, aren't you, Gin-chan?" Aizen smirked, and palmed Gin's erection.

Wait…erection? When the Hell did that happen!? Ichimaru groaned, and turned his face to the side. Damn it, why did he have to get aroused so quickly? It wasn't fair!! He heard Aizen chuckle, and a light blush spread across his cheeks.

"It seems you aren't as opposed to this as you would like me to believe…" Aizen leant down and ran his tongue along Gin's jaw, up to his ear. "Tell me, Gin-chan…am I turning you on?"

"N-no!!" This was so humiliating! Gin still couldn't fully believe what was about to happen to him. What had he ever done to deserve this? He almost felt inclined to cry. Almost.

"Hmm...well, your body is telling me otherwise," Aizen murmured, and Gin could hear the rustling of fabric. "Gin, are you a virgin? Tell the truth, now."

Gin merely nodded, unable to bring himself the say it. Aizen was obviously pleased with this answer, as the brunette bent down to place a gentle kiss to his lips.

"In that case, I will be gentle with you," he whispered, moving to kneel between Gin's legs. He pressed a finger against the younger's entrance, before slowly pushing it in. Gin gasped, automatically clenching his muscles. "It'll only hurt more, if you don't relax, Gin-chan..."

Ichimaru took a deep breath, and exhaled, willing his body to relax against the odd sensation. He barely had the time to get used to the feeling, before another finger was pushed in. Gin couldn't help but whimper, as Aizen scissored the two digits inside of him. He was definitely not used to being stretched this way, he decided right then that he didn't like it. Suddenly, Aizen added a third finger, and Gin cried out sharply, squeezing his eyes shut tightly. Sousuke continued to thrust his fingers for a few more moments, before pulling them out. Gin sighed softly, in relief, not realizing fully the implications left by the removal of the older man's fingers, until he felt something else pressing against his hole. Something hard, wide, and wet.

"Relax, Gin-chan. It'll only hurt more if you struggle," Aizen whispered into his ear, as he slowly began to enter him. Gin let out a guttural scream, attempting to twist his body away. It felt like he was being torn apart, from the inside out. Although Aizen was being gentle, the pain was still unlike anything he'd ever felt. Finally, after what seemed like an eternity, Aizen became still, having fully sheathed himself inside the younger man. Gin breath came in heavy gasps, but he was grateful for this chance to allow his body to adjust. Maybe Aizen wasn't so terrible, after all… No!! What was he thinking!? Of course he was!! Whether he was being gentle with him or not, the man was still raping him! But Gin didn't have time to continue down that train of thought, as Aizen had begun moving again, slowly pulling out, before driving himself back in. Gin choked back a sob, and bit down hard on his bottom lip. It hurt! Oh, it hurt so bad…!

Sensing the immense pain his subordinate was in, Aizen leant forward and captured Gin's lips with his own, in an attempt to distract him. The brunette ran his tongue along Gin's bottom lip, before pushing it into his mouth, caressing the sliver-haired man's tongue with his own. Meanwhile, he gradually began to pick up the pace of his thrusts, also angling them deeper.

Gin moaned loudly into the kiss, as his vision suddenly went white; all pain turning swiftly to pleasure. He felt Aizen smirk triumphantly against his lips, but paid it no mind. It just…it felt so good! What was only minutes before making his wish for death, now made his mind soar in ecstasy. Once again, Aizen sped up his thrusts, hitting harder and deeper, and Gin raised his arms to wind them around Aizen's neck, unintentionally pulling the man closer.

Aizen pulled away from the kiss, much to Gin's dismay, and began to suck and nip harshly at the man's collarbone, earning himself a soft squeal of delight from the ex-Shinigami beneath him. For the next while, he continued to pleasure Gin in this fashion, loving every sound the younger man made. He took pride in knowing he was the first man to have ever made Gin feel this way. And he would make sure he'd be the only one, as well.

Gin could feel the pressure in his groin building, and though he'd been trying to hold it back, he knew release was close. No sooner had he thought this, did his world explode in a burst of pleasure, his vision registering nothing but bright white light. He felt his seed spurt out of his body in short bursts, as he expelled his essence all over both their stomachs. Naturally, his muscles tightened considerably, clamping down tightly around Aizen's member, and sending the older man over the edge. His eyes went wide as he felt Aizen's seed pour into him, filling him completely, some of the sticky fluids being forced to leak out.

Aizen collapsed against him, not bothering to pull out.

"You may sleep here tonight, if you wish," he muttered, running a hand through Gin's soft, silver hair. "Just be ready to perform your duties come morning. And I will expect you here again, same time tomorrow night. I assume I have no need to explain why?"

Gin merely nodded, curling up against the brunette's side, and falling asleep…

xoxox xoxox xoxox

Gin awoke with a gasp, sitting up completely in the chair. He looked around for a moment, confused, before realizing that he had fallen asleep in the kitchen. He groaned, and thumped his head down on the table. He had no idea how long he'd slept, but it must have been quite a few hours, as sunlight was already starting to pour through the window. He thanked Kami-sama that no one else had decided to come into the kitchen yet. How embarrassing that would be! There was no point in going back to his room to sleep now. People would be getting up soon. With a sigh, he picked up his mug, and took a large gulp. He'd need as much caffeine as he could get.

Well damn! His coffee was cold!
