This story takes place in an Alternative Established Caskett Universe where Kate and Rick have been living together for a while. I don't think I will write about how they got together in this one. That's really not the point of this story.

Warning: This story is smutty! If you are not comfortable with that (or not yet) - turn around and leave NOW!
For all the others: Welcome to my smut-and-tease-fest! This just came to me out of nowhere. I hope it has at least some class. I try to be tasteful.

Also: This is NOT the Ignition sequel that I promised. It's in the works, though! Remember; if you have any wishes concerning that, leave a review or PM me!

Anyway, I hope you will all enjoy this. Let the teasing begin!

DAY 1

"That was…" Rick trailed off, still out of breath.

"Yeah," Kate agreed, her sweaty body sprawled on the sheets next to him.

"God I love you so much" he said and pressed a kiss to her bare shoulder.

She chuckled. "Don't I know it, Mr. Castle."

She rolled over and snuggled into his embrace, feeling his chest rise and fall and his heart thunder beneath her hand. He released a very audible breath and she laughed.

"What?" he asked.

"You sound as if you just ran a marathon!" she teased. She took in his ruffled hair and flushed cheeks. "You look like it, too."

He sighed and pulled her closer. "What can I say, Miss Beckett. You wore me out. But in my defense, I bet we just had enough sex to last us a whole year."

A corner of her mouth twitched and betrayed her otherwise perfectly blank face. "Can there ever be 'enough' sex, Mr. Castle?"

His eyes lit up and he turned his upper body towards her on the bed. "There was this one time in college when…"

Kate shut him up with a firm hand across his opened mouth. "Besides, I wouldn't want to bet on that. You couldn't possibly keep your hands off of me for that long…"

"Me?" he asked mock-innocently. "Are you talking about me? Really? Clearly you are the nymphomaniac in this relationsh…"

"Nymphomaniac! Oh, no! Now you're pushing it! The bet is on!" she declared, a challenging gleam in her eyes that he was eager to match, their faces just inches apart. A different kind of passion was now captured in the air between them.

"If we were to go without sex for a longer period of time, you would be the first to break" Kate dared him, an evil grin etched into her beautiful features.

"Oh, you have no idea what you're getting yourself into. I bet 50 bucks that I can outlast you by a week!" he countered.

She arched an eyebrow teasingly. "First of all, I find that hard to believe. You're not exactly known for being Mr. Celibacy and from what I've experienced in the last ten months or so, you are going to lose that bet."

Rick opened his mouth to respond, but Kate raised a finger to his lips in the international signal for 'shut up I'm not done yet'.

"Secondly, you cannot 'outlast' me unless - in the highly unlikely case that I break first - you would rather I sleep with some other guy."

His face fell. "Right" he said, his eyes wide as saucers at the thought of that. "So how are we going to determine who wins?"

They both thought quietly for a second.

"No kisses" Kate determined. Rick's head shot up at that.

"No kisses?" he questioned, almost pleadingly.

She smiled at him and nodded her head. "No kisses."

He pouted. "But kisses are not sex! No kisses at all? I mean, not even…"

"Okay, if you keep your mouth shut" she gave in and rolled her eyes.

"As in…?"

"As in 'hello - see you later - good night'-kind of kisses!" she explained. "Absolutely no tongue!"

"What about cheeks?" he queried and she sighed.

"Kisses on cheeks are exceptions, but no other body parts."

"Forehead?"

"Alright, forehead too."

"Neck?" he asked, his head already angling towards her exposed neck, deliciously bare for him to taste, right under his nose…

"No!" she declared, stopping his body's motion towards her with a firm hand to his chest.

"Why not?" he begged, lips so cutely pouted that she almost kissed him on instinct. Instead she rolled her eyes once more.

"Because kisses on necks are romantic and sexual kind of kisses" she explained impatiently.

"Do I get a last kiss before we officially start this?" he wanted to know, his sparkling blue eyes pleading with her. She leaned into him and let her tongue run along her lips, intending on teasing him. His eyes darkened and his lips parted slightly. He could feel her hot breath on them and inhaled the luscious smell of her skin.

"No" she whispered, but leaned closer still despite her words. He let one finger trail down the curve of her neck and she couldn't suppress the shiver even though she really tried. "This doesn't count" he whispered back and finally closed the distance.

His lips worked hers gently, tenderly until he sucked her bottom lips into his mouth and let his tongue glide over it. Suddenly she was kissing back furiously, their open mouths clashing and colliding, his tongue sliding over hers. He swallowed her helpless moan as her hands found the back of his neck, holding on to him, pressing her pert nipples more firmly into his chest. They savored the moment, fully aware that they had just vowed to live without this for a while. Rick tried to commit the taste of her to his memory, already wanting to call off the bet before they had even started it.

With a last slide of her tongue against the roof of his mouth and a small bite to his top lip, she pulled away. They both took a couple of deep breaths and then Kate got right back to business.

"Whoever gives in first and isn't able to keep their hands or lips off of the other, apart from those exceptions we just mentioned, loses the bet. Now to the most important part…"

"Wasn't that the most important part?" he asked seriously.

She shook her head and worried her kiss-swollen bottom lip between her teeth. "What are the stakes?"

A/N: This is not a 'build your own story' kind of fic, but I haven't actually decided what they are playing for yet. So if you leave a review and tell me what you think should be the winner's prize (besides honor), I will definitely consider it and possibly work it into the story!
