First, I would like to thank Sanmas-chan , Tomas the Betrayer and Coatl – their inputs were all very valuable while betaing this for me.

As you probably guessed from last chapter, this chapter contains smut/lemon or whatever you want to call it. This story is M-rated for a reason after all. Don't tell me I didn't warn you! This is not for kids! *shoos away* I think this is one of the smuttiest pieces I have ever written. u.u Now for the smut-fans… this is for you, I hope you enjoy it. ;)

As the shoji door was opened, Rukia knew she was doomed – there was no turning back now. He was there! She tried to control her panic and breathing while hiding her face from the clarity outside, once again doubting her sanity for staying there. For not running away. For… choosing this.

Who was she trying to fool? Yes, she chose this. Perhaps even before coming there – why else would she bother going home, taking a bath, putting on a beautiful kimono and her favorite perfume, as if she was going to a furtive meeting with a lover? Yes, she had thought of this possibility all along. But it was hard to admit it, to think further than that, with her heart racing so fast and her fingers trembling from anxiousness while her most feared and desired possibility became reality.

The dim light that managed to find its way through the open door behind her increased her nervousness and she was relieved when it was closed again, relishing in the darkness, blessed darkness that would hide her from herself, from her choices, from admission of what she was about to do, and from her reasons for doing so.

Rukia gulped as she heard his steps moving oh-so-smoothly towards her and breathed deeply and soundlessly, trying to calm herself.

But it was him. Him! There, just behind her!

She could not let him know. It would be her secret. He would never know. Just this one more time.

He came as well, didn't he? It was not as if she was forcing him or anything… At that moment her mind had to stubbornly remind her that she was still deceiving him, for she knew something he did not, but she tried to ignore the thought. Was he not the one that went there and asked for a girl with… 'her profile'? She blushed at the remembrance, and the possible implication of it. What difference would it make, then, that it was really her? He would get what he asked for. She was almost sure he did not know, and she would keep it like that if it depended on her. It would be just this once, just one time for her to treasure it, in full awareness this time. Her secret. Hers.

Yes, maybe she had indeed gone insane.

#####

Byakuya entered the room and looked around. It was a different one, with richer furniture, but he easily recognized the lady on the bed, timidly sitting with her back to him, just as in their last time. Good.

He admired her a little longer before closing the door – the frail structure, short height, dark short hair slightly wet - probably from a recent bath. His imagination didn't need to work hard to place the right features on her face.

Satisfied, he closed the door and as he got closer he felt a delicious, luscious scent coming from her. He wasn't expecting it, but it did not spoil the image he had in mind – it fact, it rather matched it – so he decided to just enjoy it.

The head gueisha's explanation about this woman was weird, but he didn't want to dwell on it at the moment – it was irrelevant. Rather, he added it to his own tale, imagining his little adopted sister with a double life, going there to meet him.

He was past the time of self-admonishment for indulging in this act, something that he pondered enough for the whole week. While it was not ideal, it was still preferable to the constant temptation of having Rukia under his same roof, so close; to have his improper eyes roaming over her figure, while her eyes were cast down in his presence, and his mind cogitating feelings and situations that could not be. Hopefully this would make it something banal and uninteresting and soon he would forget it all, reigning over his mind and conducting it to more useful subjects. For it to work, however, he should better make good use of his time there.

#####

Rukia felt his weight unbalancing the futon she was sitting on and half-turned to his direction, still not exactly brave enough to turn to him entirely, even if the darkness protected her identity.

She was trembling. She did not know for sure if he had recognized her – or if he would give out any signs if he did - but Rukia was almost positive he hadn't. Yet, he had asked for someone that looked like her...

No, maybe he asked for someone resembling her sister… yes, that was more probable. Yet, it was her name he called in his time of abandon. Rukia…

He desired her. It was her name that he called in that moment. Even though she had concluded that before, the thought took a new meaning now that they were there, alone, only the two of them, in a darkened room. It was him. Really him. With no kenseikan or scarf or anything that would distinguish him from any other man of flesh and bone, dreams and desire. Despite their previous encounter, she felt shy, and yet unavoidably and inexplicably drawn to him. She felt the urge to hold him, to kiss him, but her fear was greater. He did not know it was her, and that was how it was supposed to stay. She knew what her role was there. She was there to serve him, and nothing else.

But her heart started racing uncontrollably when he pulled her by her waist, this time from her front, and started to kiss her neck, like he had before. Her head fell to the side, giving him space, and she closed her eyes, relishing at the touch of his warm lips. She hoped he wouldn't notice her nervousness.

Rukia felt light bites mixed in the lazy kisses, his hot breath on her neck, his hands roaming over her body, and she knew she was breathing heavier than she should as an answer to his caresses. She tried to control it – she shouldn't make any sound, especially with his neck and ear so close.

So… close…

so… tempting…

Would it be ok if she just…

His skin attracted her like a magnet and her nose involuntarily touched his neck, breathing in his manly scent, and her lips were lured by it, unconsciously grazing over the skin that they didn't dare to kiss. She shouldn't…

His hands slithered through her body until her waist, reaching for her obi, slowly opening it, almost reluctantly. Almost… as if he knew.

Rukia gasped as his hand touched the skin of her abdomen, no longer hindered by the clothing. His lips were still traveling from her neck to her jaw, and at that very moment they brushed her lips lightly, and she could feel his ragged breath.

She closed her eyes at the feeling – was she really the one causing such a reaction in him - her marble-stone, glacial-cold brother? Was it possible that she would have such an effect on him? That it was really him, Kuchiki Byakuya, touching her, tasting her, desiring her? The mere thought stirred her instincts, clouded her mind, weakening her body with desire. The longing was almost unbearable…

His right hand moved upwards, tracing the surface of her smooth skin and bringing the opened yukata with it, brushing her breast in the way until it reach her shoulder, exposing the whole left side of her torso by removing the yukata from it.

Rukia felt naked and exposed, much more than she had in their previous time there. Because this time she knew it was really him, and for some reason… it mattered.

She felt his kisses on her shoulder, and her hand reached for his hair, tangling it in her fingers, the other hand reaching his back for support. The kisses were slowly taking whatever was left of her sanity away, tantalizing her – it was hard to form coherent thoughts. His left shoulder was just in reach of her lips, and this time she didn't resist it – she started trailing a path of light kisses on his shoulder as well.

It felt so good to be able to touch him.

Rukia felt his breath deepening and realized he had liked it, so she allowed herself to continue responding to him. His left hand grabbed her hair while his right one moved from her waist, to explore her back, brushing her breast occasionally. His kisses had traveled from her shoulder to her ear and he bit it lightly. She suppressed a gasp, but she was sure he heard it regardless. It was then that his lips moved to her jaw and again they brushed her own lightly. But this time… she moved forward and kissed him.

#####

Byakuya was surprised by the kiss, but was too soon lost in it, kissing her like there was no tomorrow. He had long indulged in his fantasy of Rukia. It had not been hard – everything she did was exactly like he had imagined. He had touched her like he would if it was really her, and she had reacted exactly like he expected… at first reluctantly, but then, reciprocating his desire.

He had always imagined she would be a little more passionate than Hisana. In the tempest that was his mind that week, he had even dared to imagine how she would show it, just like now, her breathing heavy as he abused her tantalizing nape that was just a torture to look at on their daily meetings. Trembling, shyly showing her desire… And now kissing him like this…

Byakuya felt her hands reaching for the collar of his kimono, pulling him to her, loosening it, and he was slowly losing control. He wanted her, very much, and his kiss showed it – it was passionate, possessive, a mix of deep exploring and bites on her delicious, luscious lips – he wanted to punish them for tempting him so much until they would be reddish and sore in the next day.

She was kissing him just as intensely, and delightful moans were filling his ears. His hand was now traveling under whatever was left of her opened yukata, and the moans would turn into suppressed gasps whenever he caressed her breasts more directly. It was delightful to hear it.

He felt her small hands opening his kimono, untying the obi and pushing it over his shoulders, until he was only in his hakama. As soon as he was free, his hands resumed their work, harshly grabbing her hips and pulling her to him, then feeling her rear and her legs and then reaching for her core.

#####

She gasped as he touched her intimately, and he was not surprised to find her very wet, confirming his suspicion that her moans were not only to please him. He pulled them both to lay on the bed, her body over his.

They resumed the kissing, but he took her hands firmly and guided them to the hem of his hakama, and Rukia understood what he wanted. She shyly obliged, taking off his hakama and sandals for him, and then reassuming her previous position, on top of him.

It did not take long, though, for he held her firmly and rolled on top of her, and she was once again trapped underneath him. Her body was trembling with desire and anticipation. She could feel how much taller and heavier he was, feel his hair falling over her face, his scent in the air, his breath in her mouth, the feeling of his skin burning on hers, his arousal very obvious, pulsating against her nether regions.

She just couldn't believe it.

But he felt very real as he moved in-between her legs, compelling her to open herself for him.

#####

He needed to have her now, and that was what he did. He thrust into her, feeling the wonderful sensation of her warm petite body contracting at his invasion. He heard her gasping delightfully and felt her adjusting to him, soon meeting his movements in their passion.

Rukia, Rukia, Rukia, it was all he could think of. Yes, she would feel exactly like this. She would sound exactly like this. She was driving him insane.

If only he could hear her saying…

Byakuya felt hands holding him, nails scratching his back slightly as her hand grabbed his hair and imagined for a second her beautiful deep voice… saying his name… saying whatever she wanted…

Byakuya…

nii-sama…

#####

Rukia felt him releasing himself inside her just as she reached her own peak, a characteristic warmness filling her as she surrendered in her bliss.

She was still dizzy as she felt him relaxing on her arms. She kept her hold on him, not wanting to let go.

But she couldn't hug him like that, she couldn't let him know. She had given up too much already.

That was why as soon as he moved, she released him, standing up to get dressed. She needed to collect her clothes, she needed to collect… herself.

It was with surprise that she felt his hand reaching out for her and, as finding her arm in the dark, it slid to her wrist and pulled her back to him.

"I am not finished," she heard his husky, commanding voice - it was the first time he addressed her in their chambers. His voice... just hearing him like that ignited her fire all over again.

She demurely obeyed, following his tug on her arm and going back to the bed on her knees due to the way he was pulling her. What else should she expect? Had he recognized her?

Not daring to move or ask, Rukia merely lay back on the bed, on her belly, waiting for him to say or do anything… until she felt him moving over her, one leg in between hers, his weight on her back, his arms on each side of her, covering hers. She was trapped.

#####

Byakuya could almost feel her reluctance and doubt as she stood unmoving underneath him. And that was exactly what he wanted – obedience. It was unacceptable that she would leave his side without his permission, and he certainly did not give it. And he would gladly punish Rukia, was she to behave in such an inappropriate manner… but all in due time. Firstly, he wanted to indulge in something that had been haunting his thoughts for a while…

She was still waiting expectantly when he brushed the short strands of raven-black hair off, exposing her neck, and his lips grazed the smooth, delicate skin, kissing it, licking it, biting it, testing by touch what the darkness would conceal from his eyes. Flashes of the porcelain flesh crossed his mind, in all its feminine allure, sometimes in the rare exposure of a kimono as she served him tea, in others as a gentle reminder of her delicacy in the plain shinigami uniform… ah, how that particular piece of skin had tempted him, first as a reminder of Hisana and everything he lost, and then, in a way that was unique and inappropriately hers. And yes, such inadequate temptation certainly deserved some punishing.

After abusing her neck, his lips traveled to her shoulders and then to her shoulder blade and downwards, exploring all her skinny back. He could hear delicious moans coming from her, and gasps as he bit her harder from time to time. By the arching of her body, he knew his ministrations were having the intended effect.

#####

Rukia was trying hard to control herself, but his licks and bites were creating strong sensations in her body, making it vibrate of tension and desire. It seemed he wanted to explore every piece of skin, leaving none untouched. Then she felt his hands traveling from her waist to her derriere and then searching for her core and now she knew what to expect…

She closed her eyes as she felt him positioning himself again, his weight over her, his lips on her neck, leaving marks of his desire… and realized she wanted him again, like that. She wanted to belong to him, to please him… it was as if he was reminding her he was her lord… the lord of the Kuchiki house. She remembered the many times she thought of this when she joined the Kuchiki family, if it would be required of her to please their lord in this way…

His arms would hold her underneath him, hands covering hers, his weight pressing her against the bed and soon they were one again, burning, minds absorbed in thoughts of each other, oblivious to everything but that moment, giving in to the unnamed desires that consumed them.

#####

It took long for both of them to recover from it. This time, she waited for him to dismiss her or leave the room, which he did after a while, in silence.

Silence… she had gotten used to his silence by now. No, in fact, it still exasperated her sometimes, but this time, she was glad for it. First, because it meant he had not recognized her, so it all had gone according to plan. And second… because that silence was echoing in her soul now. After such a sinful act, and yet, such a deep, meaningful one… she knew something had changed inside her. And she did not want to approach that abyss…

After so long, at least a long chapter! My time to dedicate to the fandom is limited, so I haven't started new stories (albeit the ideas keep coming u.u) or read or commented because I am dedicating all my free time to finish the ones I have. I hope you enjoyed this chapter, please leave a review with your opinion! =)

See ya!
