Okay, my gorgeous ones... the results of the poll thus far are in, and it seems you would like another chapter... It was pretty close between more lemon and a happy ending. Sorry, but I'm not a huge happy ending fan, and its just not my style to write... So I've gone with the number one choice... lemon ;) I can only hope this satisfies the ByaRuki urge :D

It had been 2 weeks since their encounter after the promotion ceremony. Much as both Byakuya and Rukia longed to see each other (and dare it be said, for a repeat of what had happened last time), duty and common sense told them that they had to be cautious in order to avoid drawing any unwanted attention to their relationship. Byakuya had been distracting himself with work, as usual. Rukia had found it a little harder to avoid thinking about her adoptive nii-sama, mainly due to Renji's persistent inquisitiveness: "Rukia, what did Kuchiki-taichou want to talk to you about the other day?", "Rukia, why were you and taichou talking in private at the dinner?", "Rukia, why did Kuchiki-taichou get so angry with Ichigo that one time?", "Rukia, is something going on with you and him?"...

Rukia had no satisfactory answer to any of these questions, and was as a result, doing her best to avoid Renji and a few of her other friends who were also above averagely nosy. Today, her retreat was the Kuchiki manor library, used mainly by Byakuya, occasionally by her, and now and then by Ginrei and a few other older Kuchikis. She figured this would be a good spot to hang out for a few hours without running into Renji or Ichigo and without causing anyone to question what she was up to, as reading had always been one of her hobbies, particularly when it involved reading up on useful shinigami training manuals. Certainly no one could criticise such a passtime. Rukia was beginning to get engrossed into a large kidou manual when a voice from close behind her startled her.

"Looking very studious today, Rukia," a cool and authoritative voice greeted her.

"Byakuya!" she gasped, realising he had managed to sneak up on her without her even slightly realising that anyone was there. Typical of his immense skill with shunpo that he would be able to sneak up on most lesser shinigami, even a newly appointed fukutaichou.

"Don't turn around, Rukia," he said in a low voice, unlike his usual business-like tone. It was still matter of fact and calm, but had a different quality to it, that sent shivers down Rukia's spine. "I believe you should call me Nii-sama in public, would that not be the polite thing to do?"

Rukia blushed, her innate sense of hierarchy never failing her. "Sorry, Nii-sama," she said hurriedly.

"Much better," Byakuya said softly, his voice in her ear, his breath tickling the side of her face and her neck slightly, sending a tingling feeling down her neck. Stepping a little closer to her, his body touching hers, he began to lightly caress her neck and stroke her hair. Rukia gasped in surprise and shock.

"Nii-sama!" she exclaimed. "Surely we can't do such things here. Anyone could walk in!"

Byakuya gave a slight, uncharacteristic smirk. "Rukia, do you know how often anyone but me comes into this library?"

"No..."

Byakuya did not reply, but continued to caress Rukia, moving his hands lower to touch and stroke her arms, moving his lips to the back of her neck, kissing her and whispering softly against her skin, sending shivers of pleasure down her spine.

"Nii-sama," she gasped, feeling his large erection pressing against her from behind. Her cheeks flushed a little in embarrassed excitement.

He moved his hands lower, to her waist, then to her hips, then sliding them underneath her kimono and hitching it up at the back. Rukia wriggled nervously. "Byakuya... I don't think we should do this here!"

Byakuya kissed the back of her neck and took her earlobe playfully between his teeth, tugging slightly and nibbling gently, making Rukia moan very quietly. He slid his hand up the inside of her left thigh, noting to himself with pleased amusement that she was already quite wet between her legs, allowing him to easily insert a finger, simultaneously circling her clitoris gently but persistently with his thumb, eliciting harsh, panting breaths and causing Rukia to bite her lip trying to stifle her moans.

"Bya...mmmhh," she groaned.

Satisfied that Rukia would not complain any further, he withdrew his hand and moved it to his own already aching member, easing himself into her in a swift, graceful movement. Rukia's eyes widened with surprised excitement. Half of her was terrified someone would walk in on them, doing something which was certainly very much against the laws of the Seireitei, regardless of who they were, which was an additional fact that would only make matters even worse. Nonetheless, Byakuya's expert touches were making her weak at the knees, and every nerve in her body pleaded for a repeat performance of the last time, silencing her conscience, at least temporarily.

Groaning softly in Rukia's ear, a sound that she would never have thought she would hear, Byakuya gripped the shelf in front of her for leverage and began to thrust. He had thought that nothing could feel better than the last time, but the added excitement of the slightly dangerous setting, and the different position seemed to increase the pleasure and excitement even further.

"You've no idea how long I've wanted to do this to you, Rukia," he growled softly in her ear, panting as he thrust hard but at a controlled pace.

Rukia didn't say anything. She didn't know what to say. She too had had more than her fair share of fantasies since the last time she had seen Byakuya, but she did not know how to voice them; she was inexperienced and even slightly shy when it came to sexual matters, and felt a bit uncomfortable about letting him know that she too had sexual thoughts and fantasies.

Byakuya moved his right hand to her waist, gripping her hard and pulling her back against him as he thrust, getting in deeper and harder as the nagging need for release built in his stomach and the overwhelming pleasure spread throughout his whole lower body. Every movement was one step closer to ecstasy and he struggled not to groan aloud with how good it felt. Nonetheless, he couldn't allow himself to come until he had given Rukia the pleasure that he wanted to show her; pleasure he had never been able to give Hisana, but that he knew he was more than capable of giving a woman. Slowing his breathing a little and controlling his thrusts, he moved rhythmically against Rukia, responding to the quickness of her breath and the quiet moaning sounds she was trying not to make, but making nonetheless. Every gasp and sound she made told him where she liked to be touched, how quick or slow she liked him to move and exactly how hard she liked to be fucked. Trouble was, the more pleasure he gave to Rukia the move she moaned and squirmed, and the more turned on he became, thus making it harder and harder for him to keep himself from just coming hard inside her.

He had to finish Rukia off soon, as he certainly wasn't going to last much longer himself. His heart pounded and his cock ached and throbbed, his balls tightening, ready to climax. "Do you like that, Rukia?" he muttered, his voice low and gravelly with arousal.

"N-n... ahh, I... ahh," Rukia muttered, struggling to make any coherent words.

"I can't hear you, Rukia, I asked you if you liked it?" he growled, roughly massaging her breasts as he maintained the steady pace of his thrusts, keeping his body at the exact angle he knew Rukia liked.

"Mmmh, I... ni-sama... I... oh yesssssss," Rukia moaned, as he finally pushed her over the edge, the sensation of his cock inside her, coupled with the rough stimulation of her breasts more than enough to send her into spasms of ecstasy.

Byakuya couldn't hold himself back any longer, gripping Rukia by the waist he pounded into her hard and fast a couple more times, allowing himself the friction he needed to push him over the edge, sending lightening bolts of pleasure and satisfaction through his lower body. "Ahh," he groaned, leaning heavily against Rukia, catching his breath, before pulling away and pulling his robe back into place, while Rukia did the same.

Gently, tenderly, he kissed Rukia on the back of the head, "I love you, Rukia," he whispered, almost inaudibly.

Rukia turned around and looked him in the eye for the first time in their whole encounter. "Byakuya... I... I love you too," she stammered back.

Byakuya sighed momentarily and ran his hand through his hair. "Rukia, I'm going to find a way to make this work, I promise you. I care about you and love you too much to treat you like this. It make take me some time, it may even cost me my position, but I will make things right between us, I promise you."

Hope you liked it. I can be persuaded to write more, presuming you didn't all hate that chapter :S A short one I know, but I had that scene in mind for a while and thought maybe it would give you lemon-fans something to enjoy ;) hasta pronto
