Unchain Me Sister

Cain awoke to something soft hitting him hard repeatedly in the head. His girl was relentless in her efforts to gain his attention. Over and over she hit him with that damn pillow. This was his wake up call this morning and every morning since she had given up on her operation jealousy. She tried a few more times while they were out to get guys to hit on her but she couldn't keep up the cutsy act. That was when she admitted to her operation jealousy and he reacted by laughing at her way of naming such a devious act. Of course he knew she felt he was laughing at her for her childish behavior.

"Get up you stupid nii-san." Finally she ceased her abuse to his head and he felt it was safe to roll out of his cocoon of blankets. A smirk played on her made up face. Furiously she smashed the pillow over his face and moved to straddle his chest. "Stupid!"

"What was I supposed to do, Setsu murder every man who looked at you then drag you here to have my way wiith you?" Cain's muffled bark came from under the pillow.

"If you knew what you were supposed to do why didn't you just do it," she raised the pillow to speak to him then slapped it down again.

Enraged Cain gripped her thighs and flipped them over. Setsu let out a scream that turned into a giggle when her brother attacked her sides. Her arms flew over her head as a sign of surrender. Cain grasped at his self control watching her arch up for his hands. Their position was inapropriate if not completely immoral. With her legs spread wide enough for him to fit perfectly between them and her back arching up offering her breasts to him. Lips hovering so dangerously close together that they breathed into eachother.

"Please," Setsu breathed drawing him slightly closer so their lips grazed. He ran his lips against hers a few times never adding pressure just barely making contact. "Cain, please," She pleaded.

Fingers dug into her hips which he brought up slamming them into his. A groan escaped his lips and he dove down to capture her mewls in his mouth. Losing his restraint he guided her hips into him again loving the vibration of her captive cries.

"Ah..." Her cry was cut short when a pillow hit him repeatedly in the face. It was all his perverted fantasy. Cain had never wanted to cry so much in his life. He wanted nothing more than to be savage with the girl above him.

"God dammit. Fucking shit child what are you doing to me?" He cursed and ranted not paying attention to her pained expression.

"I just don't know how to win with you." The pillow dropped covering his head so he could not see her breaking down. "I wish we weren't flesh and blood. But even then I'm much to plain right? I'm not your type of woman at all no matter how much I try." Sobs escaped her lips. She was tired of trying and being rejected by him even when it seemed as if he wanted her too sometimes.

Cain let out a long sigh taking her tear streaked face in his hands. This felt so familiar, tending to the wounds in her heart. Saying sweet brotherly words would be the right thing to do and Cain knew he needed to be her brother. But he also knew he could never love her like he ought to.

"You have no idea how attractive you are little vixen. You're not the only one who wishes for impossible things," he kissed her gently. "You make me wild. I am outraged at the thought of any man touching my sweet Setsu, but I do not understand why you cannot see the situation we are in." Caressing her face he wiped away the tears from her cheeks and eyes. "We share the same blood you and I. Nothing good can ever come of us being together."

"It feels good." She breathed turning her head and kissing his palm.

Recoiling his hand he gave her a slight smile tinged with sadness. "It does." He confirmed sitting up. Setsu slumped against his chest afraid to look at his face. He would tell her to go home again she knew it. Make her cease her childish attempts at seduction because this was wrong no matter how much they both wanted it.

"I love you, Setsuka Heel." Confused Setsu cocked her head at him. He kissed her hair holding her close. "Do you wanna go to hell with me Setsu?" He asked removing his shirt. His hands sunk into her hair bringing their lips together again. "We could make our own heaven. Screw society and our parents. All I want is you."

"Nii-san," she gasped at the feel of the fingers of his right hand creeping up her inner thigh. "You're not just teasing me?"

Cain pulled her hair back to gain access to her neck. He sucked hard on her pulse refusing her an answer. His right hand pushed her skirt up over her hips.

"Is it terrible to admit that I get excited when you call me that? I like it even more when you look so helpless." If she were being honest she had to admit that his wolfish grin scared her a little.

"Nii-san!" Throwing her fear aside she wrapped her arms tight around him. "I'll do everything I can to make you happy I promise."

Cain laughed seeing her overjoyed face. But a slight tilt of his head put the clock in his veiw. He had work today and he was already late. Not that Setsu and him had ever been early for a job or even close to on time. Still she went through the trouble of getting him auditions and job offers so he had no choice but to work. "Of course you will, manager. Now get off of me I'm already forty minutes late for my cm shoot."

"Who the fuck cares about a stupid cm? I need you now." A gentle pout that was too innocent and mismatched her curse had Cain laughing even more. Setsu huffed and got up to move away from him. "I knew it you were teasing me."

"Hold on, what's the rush? We have all night to do whatever you want." He took her hands and began to play with them. Running his fingers over the lines on her palms. He was really too exhausted to fight her anymore. Placing soft kisses on her palms he tried to reason with her more sensible side. Setsu was responsible for his health after all. "If I don't go to work how can I buy food for you to feed me? You insist on three meals a day."

"Mmm, but it feels good. Let's stay here." There was no compromising with her Cain concluded shoving her down on the bed. Stripping her of her tiny black skirt he layed his lips against her legs moving down slowly with the skirt until it was off.

"You know if you had been waking me up before you dressed for the day I would have had my way with you the first day." He said eyeing the sheer black panties she wore today.

Her lips twitched in a knowing smile, "liar. Ahhh." She looked down to see what had just happened that hurt so much to find him smiling up at her his tongue against her stomach. "Did you just bite me?" Her answer was another bite. "Ow, jerk." He licked away the pain effectively halting the hand she raised to hit him.

Cain moved up her body and molded his lips to hers nipping at her bottom lip until she parted them. "Virgin." Mocked Cain noting her lack of experience with kissing when they parted for air. "You make me so curious that I have to ask once more. How is it you came to be here?"

Instantly her expression shifted from pleasured and needy to cold and blank. It was always how and why with him but she did not want to tell him. In truth she had not done anything that bad in her mind. All those rumors were started about her by mean people and she felt it was justice to beat them up. And that thing with their mom was a honestly an accident. She hadn't meant for her mother to suffer and her dad over reacted by sending her to that dreadful place with that man and his girlfriend. His girlfriend wasn't so bad actually. It was her uncle and his incessant preaching. The whole truth was rather embarassing and she wanted to keep her facade of a cool independent and slightly scary tough girl.

Cain pinched her chin forcing her to look at him. "I won't try to send you back anymore. You have broken my will completely. So as your humble servant I beg you to tell me the secret." A secret between them bothered him more than anything. She always told him every detail of her day even the moments he was there for. It was refreshing to see things through her eyes and know every thing there was to know about her. "I really don't know what to think about it and that makes me curious."

"I have no secret to tell you."

Setsu closed her eyes in irritation and moved her arms to shove him off. Or at least that's what she meant to do. To her dismay she found he had her hands held above her head with one hand and his other hand was wrapping a neck tie around hers and the bedframe. What confused her most was Cain didn't own any neck ties. It occured to her too late that that was not the thing she should be worried about, by the time her mind registered what he was doing however he had her tied securely to the bed.

"I have to go to work because my manager gets on my case about money and food and taking care of myself properly. She's such a bossy angry woman that I think I'll give her a treat to make her smile when I'm done working. Until then stay put and think about what you've done."

"What the hell did I do?" Setsu yelled at his back as he made his way to the bathroom.

"You have lied to me on several occasions and you killed my mother. While I don't care enough to get revenge or turn you over to the authorities I feel you need to be punished. That is unless you want to own up to yet another lie. In which case I'll have to come up with a better punishment." He spoke from inside the bathroom stripping without bothering to shut the door. Setting the water to an almost unbearably cold temperature he got in just to rinse off from his Setsu induced excitement.

"Cain!" He continued to ready himself for work and leave with Setsu screaming at him and tossing herself around on the bed. "You fucking asshole untie me. Cain, this isn't funny." The door slammed shut locking with a deafening click. "Why couldn't I love a normal man? No I had to fall in love with a sadistic jerk."

She turned as much onto her side as she could to gain some comfort. "Better bring me a good present." She ordered forgetting no one was there to hear her.

A lavishly decorated office in a large warehouse full of umentionable illegal goings on a petite woman dressed in all black lit a cigar for the equally dark man sitting beside her. He grunted a thanks as he read over documents. The more he read the more agitated he bacame and he was biting down on his cigar so hard it broke in half.

"Honestly boss how many are you going to make me lite?" The woman asked opening an expensive hand carved cigar box filled with cigars.

"I've had enough woman. It's time to go get my wayward niece before that loser brother in law of mine calls asking for her again. I tried so hard to find her a way to be with Cain but Japanese law is clear on the issue of incest. Siblings cannot marry." He hung his head wishing for an easier problem to solve. There had to be some one around who needed to buy or sell something illegal.

"You stupid man just adopt her. Cousins are perfectly welcome to marry. Kill off Setsu and have your daughter take her place at Cain's side. Oh how romantic. Right in the middle of mourning the loss of his beloved little sister her twin cousin shows up to comfort him." An eye brow raised at the strange woman. She did know Setsu would still be the same person right? Not to mention he had already sent Setsu to be with Cain.

"Speaking of mourning beloved sisters I need to cry again." He swiped at his eyes removing his dark glasses. "Jelly hold me."

"Yes boss." Her slim arms wrapped around him and she craddled him close. "We will go see Cain and Setsuka tomorrow. Seeing their cute faces always cheers you up."

"Hm. Yes, hopefully my stupid nephew hasn't been too stuborn with that girl. Love is such a beautiful thing." He instantly perked up and pressed a button on his arm rest. It lit up and thirty men rushed into his office and another seemed to evaporate out of the shadows. "Love is the greatest..."

"God damn it I should have left with Setsu." A little girl wearing a royal violet lolita dress sulked as her grandfather preached to his subordinants about the greatness of love.

Hi again. I introduced my version of Jelly and Lori and little Maria. Sebastion too but he's just there to make Lori feel complete. The manga says Lori's an inhuman heinous black market broker when he's dressed up for Cain and Setsu so I played with that a little. Of course Lori is Lori so he loves love no matter what. I think Maria will still be Maria so maybe Lori can stay Lori. Doesn't matter most people call him boss. Bye now.
