A/N - I couldn't help myself, I just fell in love with these two over the past month and well I was trying to get a hold of good lemon Finnick/Katniss fics and there weren't as many so just yeah, here's my input :) Rated M for a reason (there's a whole pitcher of freaking lemonade in here. I warned yah). I adore reviews. Enjoy!

Insatiable

"Untangle it", Finnick said without sparing a single glance at her as he hurled the knotted rope in her direction. She caught it with one of her hands and examined it without asking any farther.

"Look for the weak spot", he instructed a couple of moments later, reassuring her it's solvable. And then the knot was undone with a single pull and a smirk spread lazily across her face in triumph. He finally glanced at her, an approving weak smile on his face. Encouraging.

"Not bad, Katniss. Now tie a knot that will take me more than five whole seconds to untie", he dared her. She looked at him and nodded, accepting the challenge with her eyebrow raised.

They used to just sit there for hours each and every day, ignoring the tight schedule etched on their arms. This was them, mentally unstable together, balancing each other out with knots and untangling them like each untangled rope solves their endless issues. From Coin, to Peeta, to Annie and then back to Snow and the games. This was them, avoiding, yet dealing with everything at once.

"Done", she announced loudly whilst tossing the rope back at him. He moved like the wind and caught it with his teeth, winking wickedly at her. She merely rolled her eyes at him.

"Why look at that", he said while examining the knot, untangling it with a single pull of his teeth. "That was almost worthy of my admiration, Girl on Fire", he noted and gestured to the now straight rope. She refrained from snorting.

"I'll never be as good as you", she shrugged, slumping against her corner of the room.

"With enough practice, you might", he simply replied, gazing over at her while mastering another knot.

"Here", he said, tossing the rope back at her, "my father taught me this one. Should be quite a challenge."
She grabbed it quickly and twisted it between her fingers, around and around.

"You have got to be joking. This is impossible", she said, narrowing her eyes at him.

"Keep going. Look for the-"

"I know, I know. The weak spot", she replied impatiently.

"You may want to lie down. It helps", he instructed, looking at her every move.

Katniss cocked her head with a questioning look, but decided to follow his instructions, resting her head on the hard concrete floor. The coldness of the stone reminded her of where she was, and there was no mistaking it really. Disctrict 13 was a much grimmer replacement to her old life, and even less free.

"Focus", Finnick said when he sensed she's got lost in thoughts again.

They do that once in a while, get lost in their own nightmares and dark thoughts. The faces of the deceased and the captives, of their loved ones and the mutual enemies, floating around, refusing to leave. And then they send this thick lifeline, helping each other rise above the surface back to their ugly grey reality in which they're helpful as nut shells, not able to save whoever is still alive. They both agreed this was the worse feeling of them all.

"I can't find the damn spot", she ranted as soon as she got back to reality, using Finnick's voice to trail back up.

He moved over to her and rested his chin on the caps of her lifted knees, careful not to hurt her.

"Put it just above your nose and look at it until you can't hold without blinking anymore. It's there." He guided her. She used his guidance, and huffed with frustration when he hovered over her, tracing the lines of the knot, making her focus on his hands instead of the actual rope.

She realized he was trying to give her a hint, yet his gentle, large hands mesmerized her as she completely forgot about her initial challenge.

She looked right back at his emerald sea eyes, the same ones that kept searching hers.

She opened her mouth in order to say something, but all she could focus on were his fingers, moving from the rope to trace the lines of her jaw, up to her lips, his thumb slowly caressing her lower wet, plump lip.

"You found it", Finnick whispered, his brows furrowed in realization.

"I found it", she repeated silently.

Finnick tilted his head and looked at her like he was seeing her for the very first time, the vulnerable and beautiful woman behind the fierce and feisty image of hers. He must have missed it at some point. How?

He moved closer to her and reached for her ear, his nose slightly buried in her hair. He found her scent intoxicating. "We found it", he murmured. His hot, musky breath on her ear sent a violent shiver up her spine.

With his nose still buried along the crook of her neck, teasing her soft skin, he reached for the rope and untangled it with a swift, single motion. A groan left Katniss's throat as she watched the rope coming undone under his fingers, feeling the urge to become that rope in an instant. To feel his heated hands all over her body, awakening her sensitive nerves.

His lips widened into a knowing lustful smirk as he kissed her neck just once, tasting her skin, her raging pulse flattering right under his lips. Katniss's breath hitched as she cupped Finnick's face with both of her hands, bringing him back to where he was, back to where he should be. She nodded briefly and pulled him down for a mesmerizing kiss, tasting the sea salt yet sweet lips of his. Finnick sighed heavily into her lips. He couldn't help himself and deepened the kiss quite immediately as he brushed his tongue across her lower lip, requesting for entrance. Her own tongue darted out without hesitation, greeting him with utter hunger.

He traced his fingers over her quite visible cheek bones, a reminder of her former life in district 12, where she would starve for the sake of her sister's health. He wanted to tell her how much he admired her. He wanted to tell her she managed to ignite a fire in the pit of his stomach the first time he saw her on the television screen while lying in bed with another woman who was using the services he was ought to give. He wanted her to know how much he needed her right in that moment, and that's the one thing that has become possible due to their current position. She started tugging at his grey shirt, lifting it up a little, exposing his muscular abdominal skin for her hand to touch. Her fingers gingerly traced his abs, appreciating the hard contrast of his muscles against her palm.

He pulled away from her, breathless, and pulled his shirt over his head, never breaking their intense eye contact. Katniss immediately seized the moment and spread her palms all over his chest, feeling his muscles come to life under her touch, his back contracting beautifully as he moved like a wave on top of her, his hips thrusting upwards and grinding against her own pelvis. She gasped with every thrust, feeling how hard he was.
He moved his hand to lift her shirt a bit, tracing the lines of her belly button. They didn't kiss; they just touched one another and watched the tender expression in each other's eyes, testing the friction between their heated bodies. Finnick's hand trailed up, his fingers tracing the sides of her breasts before cupping them both, gently squeezing them beyond the offending material of her bra. Katniss softly moaned and shifted in order to push him off of her towards to floor so she could straddle him. It took him by surprise, but her allowed her on top.

Finnick grabbed her waist and watched her as she removed her shirt. He stared at the swell of her small but firm breasts, his fingers immediately making their way to unclasp her bra. She tossed the material aside, her heated gaze boring into his eyes. She made it harder for him to breath by grinding on top of him and he could feel his lower regions twisting in agony. She put her hands on his, guiding them to her breasts. He responded rather quickly and squeezed them, groaning when he felt the soft skin filling his palms completely, her soft nipples becoming rock solid and seeking for attention under his touch. She reached down to kiss him once again.
She wanted him to lose control, to get lost in her and leave the witty, perfect attire of the 'Capitol heart throb' behind. He pinched both of her nipples in appreciation, eliciting a long moan from her parted lips.
He took over and flipped them over so he was on top again, kissing her with more passion than before if even possible, his hands restless on her breasts.

He glided down to her jaw and neck, sucking on her skin, leaving a wet trail of red hot spots for tomorrow to be seen. He licked down her collarbone as she moaned. It was like a beautiful melody to his ears. He closed his mouth on one of her nipples, sucking lightly and grazing his teeth just a little bit in order to get a reaction from her, and he did. She arched her back and practically forced his mouth to continue by doing that, whilst releasing a couple of loud, soft moans. She never imagined it would feel that good. Finnick gave her other breast the same treatment and slid his hand down her stomach, tucking his hand inside her pants securely, but just a little, teasing her for not going any further.

She pleaded between moans, the tight knot in the pit of her belly threatening to burst.

"Now, now", he lifted his head and looked at her as he pushed his hand farther down, to rest just above her already soaked panties. He groaned as he watched her mouth form an 'o' as soon as his hand pushed the material aside, running his fingers up and down her slit. He took the opportunity when she lifted her hips out of sheer excitement and slid her pants and underwear down. She was now completely exposed to him.

"You're beautiful", he murmured and kissed her stomach once, a grin creeping on his lips when her bashful face softened into a genuine, appreciating smile. He was as honest as he could be. She was truly beautiful to him.

He spread both of her legs wide enough for him to lick a line down her centre, putting extra pressure on her throbbing, swollen clit. She moaned more loudly this time, on the verge of screaming, unable to control herself especially when he thrust a finger in her, being as careful as he can get, yet mildly aggressive as the need of hearing her beautiful moans grew in him with every passing second. She felt so tight and wet around his finger, it was close to insane. He wanted to bury himself in her, and it took every bit of control he had within him to not do just that yet.
The sensation was over the top for her, and she felt an aching throb for more. She tugged on his hair gently and he lifted his head, looking right back at her when he licked his moistened lips. She groaned and brought his face back to hers, eager to taste herself on his lips. He nibbled on her lower lip playfully, his finger still pumping in and out of her.
He growled when her hand found her way to his lower regions, tucking it inside his pants securely, wrapping her fingers around his fully erect cock. She pushed him down on the floor and climbed on top of him again, forcing a groan of protestation from his mouth for having to stop his ministrations inside of her. Instead, he started moaning silently when her hand started rubbing his erection firmly up and down. His reaction got her going, since she wasn't really experienced in any of it before. She studied his expression, his eyes thrown back, eyes tightly shut. Finnick lifted his hips and helped her remove his remaining piece of clothing, leaving nothing but his bare skin to be seen. She glanced down at his erection, her cheeks suddenly flushing at the size of it, thinking there's no way it's going to fit.

As she straddled him, he gently pulled her closer to his lap and flipped them back again, cradling her in his arms, making her partially sit on his lap. He nibbled on her ear, licking her earlobe.

"Are you sure?" he asked seriously, his eyes burning on hers. His self control was slipping away from him. He had the deepest of urges to have her right there and then, and he could honestly not remember the last time that has happened to him. She slightly nodded, giving him the green, much needed light.

"Find my weak spot", she whispered in his ear as he pushed into her slowly. A low groan escaped his throat when he felt how tight and warm she really was around him, thrusting all the way in as slow as he could. Katniss gasped at the unfamiliar feeling. She couldn't quite call it pain, but it wasn't as pleasant. He searched for her gaze as he began to move inside of her, and the feeling slowly faded into pleasure, creating a whole new knot in her belly she's never felt before. Finnick buried his face in her neck, pumping in and out of her in a slow rhythm.

"Deeper", she demanded weakly in his ear. He obliged and lifted her hips a bit, changing the angle so he would be able to go deeper. His thrusts became more urgent and faster as her moans grew louder. He slipped a hand between them, finding her clit. He pinched it between his thumb and forefinger with ease, using her natural lube to his advantage. She bucked against his hand, grabbing his ass with both of her hands, pushing him even deeper inside of her. Her inner muscles started clenching around him when she was about to come, making it impossible for him to hold back any longer. He came inside of her, thrusting a few more times so she could reach her own climax. They both screamed and kissed fervently, swallowing each other's moans, both of them unable to see beyond the white bliss in their minds.

Finnick collapsed on top of her, spent, both of them breathless. He kissed her neck directly on her pulse point which was still raging.

She caressed his cheek in response, a lazy smile across her face.

"You... untangled it", he whispered to her in that very moment when he realized it's been far more than forgetting and losing everything they've got in each other. It was here to stay.
