Chapter 3

A Brother's Love

It was well over a month since Rukia's close brush with her brother and tension had run rampant throughout the Kuchiki Manor. Rukia had been on constant guard, "Nii-sama watch" as she called it. This basically entailed checking all corners for his presence so she didn't have to run into him, going to bed early, eating dinner quickly, very late at night or sometimes not at all and begging Kiyone and Sentaro to run her errand instead of her when papers needed to be delivered to squad six.

It was safe to say that after a month and a half of this she had run herself into the ground. It was now mid winter and she often shivered from the freezing weather, however she had become thinner and the cold was getting to her. Byakuya had taken notice of her ways; he frowned when he saw her scuttling around the house, avoiding him. He felt like shaking her for her stupidity around him, eating less and looking gaunt with worry. He wanted to rub away the dark circles under her eyes and tell her how much he loved her. If he didn't do it soon, he was afraid he was going to explode, go insane, insane for her, he kinda felt like he already was.

Byakuya picked up the pile of papers and shuffled them as Renji cleared his throat as he stood by the desk. Byakuya handed the papers to him, with his usual disdainful persona before capping his inkbottle and placing his brush down.

Renji bowed before slipping out of the office to deliver the papers to squad one, leaving Byakuya alone with his thoughts, he thanked Kami that there were no such things as mind readers.

Two hours later, Renji returned with a letter from squad one. He entered the office quietly, to find Captain Kuchiki as his usual aloof self.

"Kuchiki-teichou," he addressed his captain, "A Letter from squad one."

Byakuya nodded before dismissing Renji as he took the firm letter from his vice captain. He looked it over and scowled at the urgent stamp on it and quickly opened it, hoping to throw it to the side for later so that he could think of ways to seduce Rukia instead.

"Shit!" Byakuya cursed to himself as he read the formal letter, this was not happening, it couldn't! God damn it! He pulled a face that could make milk turn sour as he scrunched up the letter and hurled it at the bin, it landed in perfectly but he didn't feel like celebrating his amazing shot.

He banged his fist on the table, full of stress and anger; there was no getting out of this one. He would have to accept the mission, whether he liked it or not, and in this case, definitely not. He just couldn't get up and go to the living world for three weeks like he could before; there were other complications in his life. Who would make sure Rukia ate properly, not that she was at the moment, but who would make sure that she was cared for if she got sick? Who would make sure that she was sleeping at night? Who would be there to care for her if there was a thunderstorm?

He stood up quickly, deciding suddenly on his situation and how he would get himself out of it. He slammed the door behind him, his captains coat swishing malevolently as he went before flash stepping to squad number one.

Rukia sat by the brook that had cut its course by running through the squad thirteen barracks. She stared at it idly, barely having the energy to sustain herself. The wind bit through her Shihakusho and made her shiver all the more. She hugged her knees tightly and rested her head on them, conserving what little energy she had.

She felt close to tears, what was happening to her? She hadn't been right since that incident with Nii-sama. She tried to avoid him, yet relished in the idea that he might track her down and have his way. She closed her eyes; she wanted to be at home, in a nice cosy bed, preferably Nii-sama's with his arms around her and his muscular body pressed against her own fragile frame. She allowed herself a weak smile before some loud friends interrupted her.

"Rukia-chan!" Kiyone smiled, a little tipsy, as usual.

"How are you Rukia-chan?" Sentaro asked, also less than sober.

"I'm ok," she replied weakly as she lifted her head.

Kiyone frowned as she saw the girl's dark eyes and bags to match, she looked thin and weak, and not the Rukia she was used to at all. She was almost afraid that if she exhaled, she would blow Rukia over.

"You don't look ok, Rukia," Sentaro pointed out.

"Yes, I fine," she lied, "I'm just tired."

"You're awfully thin," Kiyone said sympathetically, "I've never seen someone so skinny!"

"I'm the same as always," she lied, even though she knew she wasn't fooling anyone.

"The captain is worried you know!" Kiyone revealed, as if she didn't already know that!

"Yeah," Sentaro said casually, "He said something about contacting captain Kuchiki about you, you know, just to make sure you're eating and sleeping well…"

"WHAT?!" Rukia yelled with all the strength she could muster, making Kiyone and Sentaro jump backwards in fear, "He's talking to N-Nii-sama?!"

"Is t-that a p-problem?" Kiyone whispered.

"N-No," Rukia said quickly, trying to hide her crimson face and her obvious change in attitude when contemplating him, "I was j-just a little put off guard is all!"

Kiyone scowled, something was definitely up, she just didn't know how complex the problem was, and wouldn't know for a very long time.

"Well," Rukia dismissed herself, not wanting to get caught off guard again, "I'm gonna go home, I'm kinda tired."

"Bye Rukia," Sentaro waved her off.

"Get better soon!" Kiyone added after her.

As Rukia walked away she only just realised how hard her heart was beating and how nervous she felt, she was short of breath and felt as tired as ever. Home was the last place she wanted to go, but her throbbing head told her otherwise.

"Yamamoto-teichou," Byakuya addressed the wise old captain as he bowed in respect, "I have just received your letter and I am delighted to be accepted for the mission, however, I am concerned for my sister who I feel is not in good health and would not benefit from my absence as I cannot be sure whether she is recovering or worsening her illness."

"Kuchiki-teichou," he said seriously after a while, "I understand how you care for your sister however, your duty as a Shinigami comes first, and you are needed for this mission as you are decisive and sagacious."

Byakuya inwardly groaned before Shigekuni continued, "I am certain your sister is capable of taking care of herself for a few weeks and if you are concerned, I will have her captain check up on her to quell your anxieties."

"Hai," Byakuya said reluctantly, there was no getting out of this one after all, "Arigato-gozaimasu."

Shigekuni gave him the details he already knew, how long he was to stay in the living world, where he was to stay and what he was to do, in other words, three weeks, at Urahara's, vanquish any Arrancar, and when not busy, laze around in a Gigai. He sighed inwardly, he knew where he'd rather be doing instead, spending an eternity in his bed with Rukia, making love to her, and when tired, pulling her close and sleeping with her tucked into him.

He bowed and dismissed himself so that he could prepare for his immediate departure in the morning. He scowled all the way to the Kuchiki house, not bothering to get his finished paperwork and file it, what was the use? He would make Renji do it while he was away. He allowed himself a small smile at his lieutenant's misfortune before pulling his sour face and flash stepping home.

Rukia gasped when she felt it, it was Nii-sama. His reiatsu was strong, she could feel it as soon as he entered the estate, powerful and violent and she heard the door slam hard soon afterwards, making her jump in shock, she had never felt his reiatsu this intense before. It made her shake with both fear and desire.

After half an hour of cleaning out her old stuff in the wardrobe she braved a peek outside, just to check Nii-sama was ok and wasn't slicing up all and sundry with Senbonzakura. The coast was clear, she gingerly tiptoed around the house, keeping as quiet as possible, anything to stay out of the firing line.

She sighed in relief as she went to the supply closet to retrieve some tape to bundle up her boxes of stuff she had. She spent a few minutes rummaging through the draws and checking along the shelves until she found it.

"Here it is!" She exclaimed to herself, smiling in her efforts.

However, her smile was soon wiped off her face as she half turned and felt that reiatsu from behind, it was Nii-sama. She froze on the spot, completely unsure of what to do. Her heart had begun to race and nervousness ran rampant through her body, heating up her veins.

"N-N-Nii-s-sama," she managed to whisper as she clung to the tape tightly.

He smiled, not to himself however, to Rukia, making her flinch at the strange action. Normally he wouldn't even think bout doing this, but this was an exception, as he knew that starting from tonight, she would never say the words Nii-sama to him anymore.

"Rukia," he replied, saying her name slowly, teasing her and making her crazy with desire.

Rukia stayed firmly rooted to the spot as Byakuya stepped further into the small closet. She let his essence wash over her, making her weak at the knees and liquefy inside.

"I'm afraid I've got some news," Byakuya said after a while, Rukia's eyes opened further as she realised the bitter edge to his voice, "I will be on a mission for the next three weeks in the living world, so you will be alone in the house until I return."

Rukia held her breath as she heard the words, making her exhale loudly and quickly as he finished. She almost shook her head, as much as she had been avoiding him, she loved that he was there, loved his scent, she loved everything, she loved him.

She gasped loudly as he suddenly pressed her against the wall. She hadn't even seen him flash step up to next to her, never mind about doing this. His palms were flat against the wall on either side of her, pinning her to him. She could feel his heart against her chest; his was beating just as hard as hers. She buried her head into his chest and closed her eyes as she inhaled, there it was, better than she had imagined, that scent, his scent.

"Will you be alright by yourself?" He asked quietly after a while, refusing to release her, she wasn't protesting after all, on the contrary she looked like she was enjoying it.

"Hai," she whispered, even though she knew she wouldn't be, three weeks was three weeks too many.

Neither of them spoke for several minutes unsure where they could take the conversation to, even though Byakuya knew where he wanted to take Rukia, and Rukia knew where she wanted to be taken.

"Nii-sama," she carefully whispered again, making him desperate to correct her all the more.

"Don't…call…me…that," he said slowly as he hoisted her up and onto his hips so that they were now eye level. She gasped as she stared into his dark eyes and tried to make sense of what he had meant.

"Nii-" she started to say but stopped herself as she obeyed his command. She was unsure what to call him, if she couldn't call him big brother then what should she call him? Not that they could hardly call themselves brother and sister; they had crossed that fragile line ten minutes ago.

Byakuya nodded his head a fraction, willing her to go on and giving her an answer.

"B-Byakuya…" she whispered making him explode inside, she sounded better than he had imagined she would at saying his name. He leant in quickly and captured her lips with his, kissing her expertly and making her freeze, she had never kissed before.

"Relax," he pulled away to whisper in her ear.

Rukia nodded and tried to relax a little as Byakuya nibbled her ear and began to kiss her exposed neck, sweeping over her skin and nipping her in places, making her jump and squeak small noises. Byakuya chuckled as he stopped for a few seconds, she was so innocent but he knew she was enjoying is as she had closed her eyes and had a look of sheer pleasure on her face.

He lifted his head and caught her in a kiss again, except this time she was relaxed and ready for him. She kissed him back after a while and didn't care to realise that her hands were threading through his hair. He nibbled on her bottom lip, asking for entrance and relished inside as she deepened the kiss and allowed him.

She had already begun to remove his blasted Kensaikan, which were getting in the way, when he brought her away from the wall and started to make off with her into his room. She was filled with both nerves and lust, trusting him to be gentle with her, as she didn't complain as to where he was taking her.

"Be gentle with me," she whispered as he kissed her collarbone hard but soon opened her eyes as she heard the emergency bell ring.

"The bell…" she said reluctantly.

"It can wait," he murmured, "You come first."

The pair froze as they heard footsteps approaching; Byakuya panicked and set Rukia down before sorting his ruffled hair while Rukia tightened her already loose sash, thanks to Byakuya, and sorted her marked neck out by pulling her Shihakusho around her closely.

"Kuchiki-sama," one of the servants called from around the corner as Rukia backed away from Byakuya. Byakuya scowled at being interrupted, he was so close. His lust turned to anger and it wouldn't have surprised either of them if steam had come out of his ears.

"Kuchiki-sama," the young man called again as he turned the corner and came across a furious Byakuya and a backing away Rukia who was walking down the corridor rapidly.

"Nani?" He asked gruffly, desperate to dismiss the man and seduce Rukia like he wanted to, kami he could kick himself for not doing this sooner, now he knew that Rukia was as desperate as he was, it made him all the more angry.

"You are needed at the tunnel gate Sir," the servant explained quickly, "An order has been issued from the head captain, and you are to attend to your mission as of tonight. The head captain has allowed ten minutes to get ready for the mission."

Byakuya watched in fury as the young man bowed and excused himself as the bell continued to ring. He turned on his heels and sped after Rukia who was already standing outside his room, waiting to help him get his things together.

She had a look of both guilt and disappointment, giving him mixed signals, so she was full of shame for what had just transpired but she was disappointed and wanted more? God women are so difficult! He brushed past her deliberately and took her hand quickly, pulling her in his room with her before letting go again and leaving her in the middle of the room. He hurried around, trying to drown out the bell with his thoughts which carried on in its monotone noise. He took Senbonzakura quickly by his side and searched for his Gikongan and became all the angrier as it has disappeared.

Rukia cleared her throat and held out the soul candy with a small smile as Byakuya continued to rummage around in panic.

"N," she started but stopped herself with a bigger smile, "Byakuya-sama, Hai."

Byakuya turned suddenly and faced her before taking it off her carefully. He placed it in his pocket and stood in front of Rukia who was trying to keep warm as she found it freezing tonight. He bent down and cupped her face in his hands before kissing her gently. The bell prompted him, making him pull away reluctantly. Rukia frowned as he did so, she equally didn't want him to go, and three weeks was a long time.

"Rukia," he said making her look up at him, "Please take care while I'm gone, and I want you to get well. You're awfully thin and tired, eat and sleep is my advice and if you don't, you will be punished."

He had a cheeky smile and a cheeky sparkle in his eyes, making her smile as hard as she could, which was still pretty weakly.

"Farewell," he said quietly before bending down again to kiss her forehead, "I'll see you in three weeks."

"Be safe," she begged as she embraced him tightly and in taking his scent for the last time, well until he returned anyway, tears were beginning to form, "Please come back alive."

"I couldn't leave things like it is Rukia," he assured her and he stroked her raven hair, "We still have to carry on our alone time, and don't think your getting out of it."

Rukia let go of him and wiped her eyes on her sleeves but gave a small laugh at his words.

He gave her a genuine smile, something she had really never seen, before flash stepping away, out of the Kuchiki estate and into the pitch-black night. Leaving her resting against the doorframe, cold and alone.
