A/N: I'm sorry, I'm sorry, I'm sorry! It's been so bloody long. I didn't mean to go so long. I swear I was meant to have posted this ages ago, but...I guess I didn't. Meh.

Still feeling high from the previous afternoon's encounter with Jack, Kate stood at the doorway to her tent, watching Jack across the beach, a slight smirk written on her face. Every now and then, Jack would raise his head, and look around the beach. On seeing her, he would smile, nod and wink at her. To which Kate rolled her eyes, laughed and shook her head at him. She knew he was trying to tease and play with her, as he'd mentioned before, but currently, Kate thought all that winking at her was irritating.

It was when Jack walked along the beach, and as he passed directly in front of her, a mere few feet away and stopped to bend over and re-tie his boots that the games really began. Kate couldn't say she didn't like the view, she also couldn't say that she hadn't, even for the briefest of moments, wished that he wouldn't straighten and walk on, that he wouldn't sneak into her tent, and completely ravish her as he'd done before. Hell, maybe even slow, sensual sex would be okay, but slowly…and dangerously so, Kate knew she did actually, want to have sex with him again, and that maybe sex in a kitchen would be okay, as long as it was with him. As soon as Kate realised what she was thinking, she mentally slapped herself, stopping and muttering "It's just sex; it doesn't mean anything…its okay to want sex. Sex is fine…it's just sex. No strings…"

As Jack straightened and stood up, Kate shot him an 'if looks could kill' glare, and turned away from his, marching off down the beach in the opposite direction. Jack smiled, allowing himself to watch her walk away for a moment too; knowing that in fact, he was beginning to affect her.

By early evening Kate was pissed off at him. He was being so smug, and smarmy and…ugh! For two hours she'd been out in the jungle just to get away from him. As much as she hated to admit it, he really was doing something to her. He was winning this game, and she hated that.

It was infuriating, the looks and winks and smiles he gave her, like he knew she did want to sleep with him again. Kate sighed, he was crazy. And when he talked to her, he continually teased her, annoyed her, and acted so god damn cocky.

She'd had enough. She marched back to the beach and straight over to him. She gave him a glare before interrupting his conversation with various survivors.

"Hey, Jack?" She interrupted them.

"Kate? Everything ok?" He asked her, his eyebrows raised slightly.

"Uh…no." She told him. "Kinda had an accident earlier." She lied. "I slipped and fell, my back aches and I kind of scratched my stomach…I thought…maybe you could check me out." She shrugged. Jack grinned widely, holding back laughter at she'd just said.

"You want me to check you out?" He smirked.

Kate opened her mouth and closed it again before responding. "Not me." She rolled her eyes. "My injuries." She told him.

"Ok, right." He nodded.

"So?" He was really frustrating her today.

"So what?" He asked her.

"Get up." She grabbed his arm and pulled him up. "I need you to check out my injuries, in my tent."

"Oh, in your tent, huh?"

"Shut up, Jack." She sighed and pushed him into her tent. She sat down on her bed and looked up at him. "You've been really annoying, lately."

"I have huh?" He smiled. "So…" He put on a more serious face, "where are these injuries of yours?"

"Don't have any." She stated simply.

"You don't?"

"Nope." She smirked up at him. "I just needed an excuse to get you away from everyone else."

"Looks like it worked."

"Uh huh." She gave him a smiled and raised her eyebrows. "But since you're here anyway…you might as well check me out. Just to be safe."

"Just to be safe." He nodded, sitting on the bed beside her.

"So Kate…what needs checking out today?" He asked her and she pulled of her tank top.

"Sort of everywhere." She said lying down. "But here might help." She smiled at him, pointing to her collarbone.

"Here?" He asked his hands lightly brushing over her skin. She nodded. "So…I guess I should kiss it better, then?" He winked at her.

"You should…but stop the winking, kind of creepy." She laughed as he leant down to kiss her collarbone.

"Anywhere else?" He asked after kissing it a third time.

"Well…all down my front?" She looked at him. "That might need checking out."

Jack simply obliged and began gently kissing his way down her chest and stomach. "What about these?" He asked as his hands came to rest just beside her breasts.

"Well yes, they might just need checking out too." She smirked as he snapped off her bra and lowered his lips to her breasts. First one, and then the other, softly caressing them with his hands, as his tongue swirled around her nipples. She let out a soft moan as he did so. And he looked up to smile softly at her look of happiness.

"Feeling better?" He asked her, kissing his way up her neck and along her jaw.

"Yes." She breathed. "Much more relaxed, less tense." She smiled bashfully at him. "Although…it's not just my top that needed checking out." She giggled.

"Not just your top, eh?" He asked, kissing her softly on the lips before trailing his hands back down her chest and stomach towards the top of her jeans. "I'll have to see what I can do about that." He said pulling off her jeans, casually kissing her legs, as he revealed her skin, inch by inch.

"You missed a spot." She told him, as she pulled off his shirt after kissing him.

"Trust me." He smiled. "I know I did, I'm saving that to last." He chuckled as she laughed.

"I guess that's alright then." She said as their tongues met in a ferocious battle.

"I'd say so." He said, shifting down her body and kissing her hips before tucking his fingers around the sides of her panties and ridding her of them.

Jack traced his hand back up the insides of her thighs, and once again, kissed each hip, before moving his concentration somewhere else, somewhere more sensual. With his hands he forced her legs open, and ran a finger over her, before leaning down to kiss her somewhere he knew that would make her squirm.

She gasped, her eyes wide, as his tongue slid over her most private parts. She'd be lying if she said she didn't enjoy or even want it, it had been what she'd been hinting at, but she hadn't known he'd actually go ahead with it. And she definitely, hadn't imagined it to feel like this. She moaned softly, and he smiled slightly before continuing to love her with his skilful lips and tongue. "Jack…" She moaned as he pulled away and grinned at her.

"I told you." He said moving his attention up her body, caressing it with her hands. "I told you I would turn you on and that we would have sex again…and that you'd be begging me." He smiled remembering their romp in the jungle.

"I never said we wouldn't." She said with a soft smile, reaching up to bring his lips to hers, where she could taste herself on him.

"Ah, no not exactly, but you implied it." He said leaning in for another kiss.

"And," She paused for effect, "we haven't exactly had sex yet, have we?" She smirked.

"Well, I'd better see what I can do about that, then." He said kissing her forehead.

"You'd better." She told him, as her hands found the waistband of his jeans, and tugged on them.

Jack soon had the very naked Kate pinned down below him, as he hovered over her, equally naked. Jack lowered his mouth to her neck, softly kissing his way down, till he reached the bottom of her neck where he began to suck. For just a moment Kate had lost control of her mind, allowing him to do so just for a second.

She pushed his head away. "Jack…" she sighed. "You can't do that…you know we can't."

"Why not Kate?" He asked her.

"You know why." She sighed. "This is just sex. You shouldn't be trying to give me a love bite…besides, then, everyone would know what we've been doing lately. And I don't have anything to hide my neck with. You just can't." She said adamantly.

"Fine." He said, and then gazed down at her. "I'm sorry."

She reached out her arm, and ran her hand down the side of his face as he straddled her. "It's okay." She smiled, as she pulled him down so that their mouths could dance the tango they'd both gotten quite used to.

As they kissed, Jack manoeuvred himself, so that he was in just the right position above her. Mid-kiss Jack entered her, and swallowed the tiny gasp that came from her surprise.

As Jack thrust into her, in a slower more gentle speed than he had done previously, he kept his eyes focused on her face, observing the look of ecstasy splayed across her face. Without his eyes leaving her beautiful face, he managed to kiss and touch every inch of her skin, before gazing up at her face, his hovering just over hers, as he felt her reach her climax and cry out his name. He ducked his head, to give her a tender kiss, as he too came.

As he collapsed over her, he swiftly rolled them over so that he wasn't crushing her, but instead she was resting peacefully on his chest.

Kate sighed, with a slight frown. "You alright?" He asked her.

"Yeah…yeah, I'm fine." She told him and kissed his chest, as if to make a point.

"Kate." He sighed, knowing she wasn't quite fine. "Tell me, please?" He asked and kissed her hair.

"It's just…we probably shouldn't get too used to this." She told him.

"You thinking it's a stupid idea, again?" He asked squeezing her, as if to tell her it really wasn't.

"Not exactly…just not the best idea." She ran a hand up his chest. "It's just…" she sighed, "what happens when my pills run out, and the condoms all run out too…what happens when we have no protection at all, and you…or I…decide we'd like our sex fix?"

"Oh, Kate…"

"That's why I don't think it's such a great idea. We shouldn't have started this casual sex thing in the first place." She shook her head sadly.

"Well…" Jack ran a hand through his hair, as they both sat up. "How many months you got?"

"I dunno." She sighed. "Two or three…"

"Hmm…can't we just…cross that bridge when we come to it?" He asked her softly.

"I don't know." She shrugged. "We could…but…it's just…we shouldn't get used to it. This 'arrangement' can't last forever." She reminded him, after all, it was just sex. "And if you do want to…if we do decide to carry on this 'thing'…we shouldn't do it so often. I mean, twice in two days Jack." She sighed. "We shouldn't be doing this…at least, not so often. It'll only be harder when we stop…" She told him.

"Ok." He ran his hand through his hair. "Lets just see what happens? Hmm?"

"Okay." Kate smiled weakly. He shook his head slightly, as he smoothed down her hair.

"We should probably go out soon…before they think the monster's gotten us." He chuckled.

"Yeah…" She agreed as Jack passed her, her underwear.

A short while later the two friends emerged from Kate's tent, Kate still glowing, and Jack smiling smugly. They moved over to their friends and tried to inconspicuously slip into the circle, and failed.

"We were just talking about you." Charlie told Kate.

"Uhh…right…Why were you talking about me?" Kate asked him.

"Not you, Kate." He waved his fork between Jack and Kate. "You as in plural. You as in you and Jack."

"See…we wondering what you two were doing in Kate's tent." Hurley said. "Dude, we heard you scream." He smiled and nodded at them. "We know what happened in your tent."

Kate blushed, wishing the ground would open up and swallow her, whilst Jack just shook his head.

"We weren't doing anything like that." Jack told everyone.

"Yeah, right."

"We weren't, she fell earlier, I was just checking her injuries out." Jack denied anything had happened between them.

"Kate, dude?" Hurley turned to her.

"It's true." She shrugged. "I did fall, and he was checking out my injuries."

"So why the screaming?"

"Her muscles were tense…I put too much pressure on a bruise as I was massaging it." Jack informed the group. They seemed to believe him, but Kate was snickering behind her hand, how couldn't they see through him, he was such a bad liar.

"You're a crap liar." She whispered to him, and he just laughed, shaking is head.

"But they believed it." He whispered back.

"I don't." She smiled at him.

"That's because…" He whispered into her ear, "you know different. You know what happened in that tent, and why you screamed." Kate shoved his shoulder and laughed at him.

"Pathetic guys, absolutely bloody pathetic." Charlie said.

"Huh?" Kate asked.

"It's absolutely pathetic that you two," he pointed at them, "have been all over each other since day one; and how you're not actually 'together' officially. You're all over each other, it's pathetic. Bloody pathetic guys." Charlie told them, walking off in a huff.

Jack laughed and looked at Kate who smirked at him with her eyebrows raised. Oh, if he only knew…

A/N: You know what to do. Make my day. Let me know that you love/hate me. It's all good.
