Chapter 4

Kate quickly walked through the jungle and sighed in relief when she saw the entrance to the caves. It had been a dark and cold walk and she was glad to be here. She frowned when she walked through the entrance, it was pitch black. Surely if Jack was here he would've made a fire, it was too cold and damp to sleep here otherwise. She wondered if she had guessed wrong about his whereabouts. However, as she crossed the threshold and entered their old dwelling place, she sensed his presence. It made her sad to think he was out here all alone and in the dark. Suddenly she heard a noise behind her and gasped when she felt an arm grasp her around the waist and pull her back against a hard body, while the other arm wrapped around her neck. On impulse Kate gasped out his name. As suddenly as she was grabbed she was just as quickly let go.

"Kate?" she heard his raspy voice whisper near her ear. She felt shivers dance down her spine and she quickly turned to face him. She couldn't see him in the pitch black except a general silhouette of him.

"Oh Jack, I'm so glad you're here I've been so worried" with that she launched herself at him wrapping her arms around him tight. She could feel him relax for a slight second and then he stiffened and tried to move back. No way, Kate thought as she felt him try to disengage from her. Taking a deep breath Kate took the plunge and for once in her life took the big risk. She grasped Jack and lifted her face up and kissed him. It was pure dumb luck that she actually made it to his mouth in the complete darkness. She felt his resistance so she gently ran her tongue across his lips begging for entry. She pressed her body against him and was pleased to feel his hardness through his jeans. Kate continued to kiss and lick at his mouth trying to break down his defenses. She was rewarded kindly for her efforts when she grinded her pelvis against his. Suddenly his arms were around her waist grasping her tight against him. His mouth opened and their tongues engaged in a duel. Kate felt heat, lust and passion sweep through her body as she tried to push against Jack even harder. She wanted to just be enveloped by him.

His hands were sliding down her body being followed by her own chills of want. He grasped her ass and pulled her tight against him. She groaned against his mouth, kissing him harder wanting to taste all of him. She ran her hands underneath his shirt touching every part of his bare back she pushed the shirt up and gasped for breath as he tore his mouth away from her to discard his shirt. As he was doing that Kate quickly ripped off her own and was soon back in his arms his mouth on hers, his tongue intertwined with her own. His hands burned against her bare flesh, and she whimpered when she felt him moving her backwards without breaking contact. After walking a bit he pulled her to a halt and slowly pushed her to the ground. Kate was pleasantly surprised to feel an airplane seat underneath her. She stretched out and whispered his name as he settled on top of her. She quickly wrapped her legs around his waist and pulled him close feeling his pelvis rub right against hers. She ran her hands across his bare skin but it was driving her nuts to not be able to see his face. She wasn't sure how Jack seemed 100 at seeing in the dark. As if sensing her frustration she felt Jack pull away from her slightly, still attached to her by her legs wrapped tightly around his waist. She heard some clicking noises and suddenly the cave was softly lit. She saw that Jack had a battery operated lantern from the hatch. She then looked up and realized he was staring down at her with awe, confusion and lust in his eyes. There she was pinned under Jack his bare chest pressed against hers. Her legs were tight around him and suddenly everything seemed to stop.

Kate looked into his eyes and saw in him the Jack that she loved. She smiled and gently grazed his cheek with her fingertips.

"What are we doing Kate? What are you doing here?" Jack said not taking his eyes off of her.

"Well you're about to make love to me" she whispered huskily and happily felt his hardness now pressed against her own center only separated by a couple layers of denim. She knew that if she didn't play it right she would spook him so she lifted herself off her back and put her face right up to his their lips only slight inches apart. "And I'm here cause I've been looking for you all day Jack Shephard. I know you want to ignore whatever this is between us, but it isn't going to work." She said bravely.

"Yeah, how can you be so sure?" Jack asked his voice hoarse.

"Because I want you, and I want the man that I love to make love to me. I want him to finish what he started against a tree outside the hatch, except this time when he makes me come I want him inside me coming too." Kate said seductively. Unfortunately the seduction didn't work as she planned. Jack's eyes flashed black and he quickly moved away from her and stood up.

"No Jack," she whimpered just as quickly jumping to her feet and standing in front of him. She could feel how tense he was and she could sense he was becoming agitated. Kate gently stroked his face and hair as if attempting to tame a wild beast. "Stop it Jack, stop pushing me away" Kate said with force in her voice.

"Oh right, I'm supposed to take advice from you about pushing people away?" Jack said his voice cold and bitter.

Kate sucked in a breath as she heard the words leave his lips, but she also saw him avoid her gaze as if the words were hurting him as well. It dawned on her that Jack was trying to push her away on purpose and that he was going to try to be cruel about it, but that they were just words and that there was no feeling behind them. If that's how he wanted to play it that was fine with Kate, she wasn't going anywhere.

"What the hell do you want from me Kate? I'm sure there are better things you could be doing with your time right now, I'm sure Sawyer wouldn't mind the company." Kate could almost hear him choke on those last words.

"I'm here because I'm worried about you, I'm scared for you. You're obviously not well right now Jack; I just want to make you feel better." Kate said trying to get him to look at her.

Jack let out a harsh laugh, "Oh I see you think I need a pity fuck huh? Well that's real kind of you Kate but no thanks I think I'll pass."

Kate felt the anger boil inside her at that one "A pity fuck? You think I'm here for a pity fuck?" her voice raising. "If I wanted to give you a pity fuck I would have crawled into your bed a long time ago Jack," she said exasperated. If he wanted to fight she would fight, as long as it made him feel better and got the job done. She was rewarded by Jack's head snapping back to her and his glare met her with fire in his eyes. There it is Kate thought, she was making progress, it might be ugly but it was progress nonetheless.

"So is that what you think Kate? Poor Jack, he must be so lonely I'll just crawl into his bed and give him something to shake up his world a little." Jack sneered in Kate's face but she held her ground. "I am so fucking sick and tired of everyone assuming that they know me. If something goes wrong, Jack will fix it, got a problem? Jack's your guy, it's not like he has anything going on in his pathetic, miserable life so he'll jump at the chance to help you out. I'm sick of it, what the hell would you people do if I had died huh. Everyone on that god damn beach acts like they couldn't tie their own shoes if I didn't tell them how to do it! Do you know who I am? Do you Kate, cause I'm pretty sure if I unloaded all my dirty little secrets on you and them, you wouldn't be able to get away from me fast enough. You act like you are some horrible person because what Kate, you killed someone? Hell Kate I've done worse than that on a good day!" he shouted at her and then quickly turned away his shoulders moving quickly up and down as he tried to regain his breath.

Kate felt her heart leap in her chest as she watched Jack try to regain control of himself. The fact that he had just said he had killed people, possibly numerous people, made her pause for a second, but it didn't matter to her. She loved him and if he was the next Ted Bundy then the hell with it, she would love him anyway and they could easily spend the rest of eternity burning in hell together. It may be sick and twisted but Kate didn't care as long as they were together. Shit, even Bonnie and Clyde go to go down with one another. She quickly moved to his back and wrapped her arms around his waist and pressed her face against his bare shoulder blades and just breathed him in. He stiffened at her touch but she just squeezed him tighter.

"I can't do this Kate, I can't please let me go." He asked her softly.
"No" she said into his back

"Kate, please, I'm too wired and I'm going to snap and I need you to leave because I don't want you to get hurt" he pleaded with her.

"I'm cold" she said, "And since you didn't have the decency to make a fire for us, it's up to you to make me warm." With that she walked around to face him. He was watching her with guarded eyes. "If you're going to snap Jack then do it, I'm not going anywhere though." She pressed close to him "You're wired Jack and that's ok, you need release baby and I'm here for that."

Jack groaned in frustration and tried to move away from her but she followed his every move, "Kate I can't, you're right but I can't...not like this. I don't want to hurt you."

"Jack I'm not going to break, whatever you want I'll do. I love you Jack, more than I've ever loved everyone in my life and I guess if I have to let you screw my brains out to prove it then I guess I'll just have to make that sacrifice." She said with a smirk, she saw his lips twitch slightly before he frowned again. More progress, she thought to herself.

"I love you too," he whispered, "You deserve candles and romance and silk sheets not a hard, fast paced fuck"

Kate shivered at his words, he loved her too. She stroked his face. "Did it ever occur to you that I don't care what it's like as long as it's us together? I'm here Jack because I love you and I want to be there for you. Guess what? You are going to have plenty of time to make love to me slow and easy. Cause buddy this is definitely not a one time deal we're together after this and if you have a problem with it too bad." She said her hands on her hips. He smiled at her tone. "There you go a real smile, I knew you had it in you. I'm not going to shatter Jack I'm not some innocent school girl, though I would totally dress in a uniform and put my hair up in pigtails if you wanted." She smiled as he laughed at that. She had him and it was time, she could still see how tense he was and she wanted to take that away for him. She slowly slid her hands up his chest gently tugging at his chest hair and moved her hands up to wrap around his neck. She felt his arms wrap around her. She stood on tip toe and whispered in his ear, "Fuck me Jack, I want you to take me right here and now I'm yours" she felt his arms tighten slowly so she rubbed against him. "Finish what you started this morning, take me against the wall and screw the living daylights out of me. Do it Jack I want it, I want it hard and fast." She licked at his ear and gave a moan and with that Jack finally snapped.

Kate found herself pinned against the cave wall as Jack furiously wrestled with her jeans, getting them undone they slid to the floor and Jack lifted her off the ground and out of the garment he gripped her thighs and led her legs to wrap around his waist as Kate clung to him, scratching her nails down his back being held by his arms and the wall. He supported her with one arm pressing her back against the wall as he undid his own jeans and Kate let out a groan when she realized he wasn't wearing any underwear. He pulled his hard member out of his pants and didn't even bother pushing the denims down. He slipped his hands between her legs and pushed the crotch of her panties to the side and felt her wetness. With no warning Jack thrust inside of her causing her to cry out his name as she tried to adjust to his size. Kate was sure she had never been with a bigger man. Before she could even gather her thoughts Jack was thrusting in and out of her at a hard pace slamming her back against the wall. The feel of her back rubbing against the wall surprisingly only hurt a little. Kate couldn't think of any pain as her mind was wrapped around the fact that Jack was inside her and literally screwing her senseless.

She hugged him tight to her and stroked his hair and his back whispering and whimpering encouraging words into his ear, telling him everything she felt. Everything he was making her feel. She could feel her own release coming up on her and was surprised at how soon it was. She clung to him and just felt as he thrust in and out, in and out. Soon she came with a shout, clenching her inner muscles round him screaming his name and how much she loved him. When she came back to Earth she rested against him as he moved hard and fast inside of her. She shifted so she could see his face and saw raw determination on his face as he loved her.

"Jack," she moaned "look at me"

Jack's eyes snapped to hers and she held his stare as he moved within her.

"I love you" she whispered, refusing to break the stare even to close her eyes in ecstasy. "I love you, I love you so much"

With that Jack grabbed her legs and hoisted her higher on him Kate could feel the new position throughout her body and could feel another release coming.

"Oh god Jack Oh god" she said still staring into his beautiful eyes, "I'm going to come again, please come with me please oh god please." Unable to keep her eyes open any longer Kate threw her head back and felt Jack attach to her neck with his lips thrusting into he relentlessly. Kate had never been fucked this hard and she couldn't stand it as the next wave of pleasure hit her. She screamed his name as tears poured down her face. It was the strongest orgasm she had ever experienced. As she was still writhing in ecstasy she felt Jack shout her name against her throat and release inside of her. His release was hot and she could feel him fill her up.

Kate wasn't sure if she blacked out or not but when she came to she was being cradled straddling his lap as he sat on the floor still inside her. She wasn't sure how they got there but she didn't care. Using all of her strength she lifted her head off his shoulder and looked at him face to face. His eyes were closed and he was breathing heavy. She leaned forward and nuzzled his face gently. He stirred and opened his eyes and they looked at one another. She smiled at him and met his mouth with a sweet and sloppy kiss. His grip tightened on her and he pulled her close. Breaking the kiss to breathe he kept one arm around her waist and with his other hand ran his fingers through her hair and cradled her head against his shoulder. He felt as a sigh of contentment ran through her body.

"I want to tell you what I've done" his words almost an echo of hers not so long ago.

She moaned against his shoulder, "Tomorrow baby we will talk tomorrow right now I just want to feel you." With that she sat up and let out a surprised whimper as she felt him harden again inside of her. She smiled slyly at him. "We'll talk later right now we have other things to take care of" she said kissing him passionately. She quickly moved to fully undress as he did. When they were both naked Kate took her place back in his lap enveloping his hardened member inside of her and began moving slowly up and down feeling the pleasure run through her.

"Thank you" he whispered into her ear and the love and affection in his voice nearly broke Kate's heart.

"You don't ever have to thank me for loving you' she whispered back. No more words were spoken except the words of passion as the two made love into the night the cold around them completely forgotten.
