"So what do you think?" Gibbs asked.

"Well I'm glad to see you have your priorities right," Abby teased, looking at the expertly crafted wooden bed frame in front of her. She ran her fingers over the engraved bedhead before moving to stand next to Gibbs and pulling him into her arms.

"I love it," she said, wrapping her arms around his waist. "And do you realize this is our first bed…like our first proper shared bed?"

"It's why I wanted it to be special."

The bed took up a good portion of the room, situated under the window at the end of the cabin it dwarfed the smaller cot that Gibbs had set up months ago for them to sleep on. They'd made do with it though. On the occasions they hadn't fallen asleep on the floor in front of the fire after making love they'd collapsed onto the small bed, Abby usually sprawled on top of Gibbs.

She was surprised the metal holding the bed together was still able to stay upright considering they'd given it a fairly intense workout. There wasn't much room to move on it but somehow it had held strong under their weight and a substantial amount of rocking and thrusting.

"So should we test it out to see how sturdy it is?" Abby grinned impishly.

Gibbs raised an eyebrow at her. "You questioning my woodworking skills?"

"Nope, I'm just saying that we can get a bit carried away sometimes and the scientist in me says we should test it's durability to make sure it can withstand the pressure."

Gibbs returned her grin, she was right, when they were alone at the cabin they did tend to let their hormones run riot. Sex during the week was much different than it was on their days off at the cabin. The majority of the time their cases influencing the where and when that they could be together. They didn't have that problem here, instead they were free to give into their needs whenever the desire struck them.

"You know, everyone will think this place is our dirty little hideaway when we tell them about us," Gibbs suggested, his fingers trailing down the side of her face.

"Isn't it?" Abby asked, her hands roaming over his back. "We do seem to be naked a lot of the time we're here."

Gibbs leaned forward to press his lips lightly to hers, mumbling, "Whose fault is that?"

"Well I can't help it, as soon as I see you working…your hands gripping and sliding over the wood, I want them on me."

In response to her words Gibbs settled his hands on her hips and smoothed them around to cover her ass. He patted her lightly and Abby thrust her hips forward, bumping her groin against his.

"Guess it's good we have a bed now then," he whispered, "we were starting to run out of surfaces to use."

Gibbs had built the pieces of the bed in his basement and then brought them to the cabin in the back of his truck, along with the brand new mattress now sitting within the constructed frame.

"So what do you say Gibbs, you prepared to put those hands of yours to use and take part in a worthy scientific experiment?" She asked, walking backwards several steps so they were standing halfway down the bed.

Turning their bodies Abby pushed Gibbs and he willingly let himself fall onto the bed. She gazed down on his prone form for a few moments before grasping onto the bottom of her t-shirt and drawing it up over her head.

Gibbs' eyes wandered over her exposed creamy skin and he groaned. It didn't matter how many times he watched her slowly undress or frantically rip the clothes from her body, each time sent a rush of deep love and arousal through him. And this time was no different.

It didn't matter that they'd been together just hours ago in his bed at home before leaving for the cabin. They made the most of every opportunity they got, and with the way Abby could quickly send blood rushing between his legs Gibbs wasn't about to turn down any attempt to seduce him.

His focus on the dark green material of her bra and the way it brought out her emerald eyes was interrupted when Abby slowly undid the button and zipper of her jeans. Gibbs swallowed as she lowered them, his own jeans suddenly feeling tighter at the appearance of her matching green panties.

He grinned up at her as Abby looked confidently down on him. She knew exactly what she was doing to him and she was loving every second of it. Gibbs fought the urge to reach down and massage himself when her eyes traveled the length of his body, stopping on the growing bulge in his pants.

Instead Abby did it for him, Gibbs moaning when her hand covered him. She cupped him gently and squeezed just once before seeking out his belt and with knowing hands she undid the leather strap and moved onto his jeans.

Gibbs lifted his hips when Abby slid them down his legs, his tenting boxers now the only thing keeping his hardening erection hidden from her. She could've easily removed them at the same time but Gibbs knew how she liked to tease him, so he wasn't surprised when she climbed on top of him, his boxers still in place.

"You don't wanna make the bed up first?" Gibbs asked, his fingers immediately seeking out contact with her bare skin.

Abby shook her head. "That would take too long and I'm kinda in a hurry."

As if proving her point she took hold of his t-shirt, pushing it up his chest and dragging it over his head. Her mouth sealed over one of his nipples, her tongue licking and her teeth tugging.

Gibbs' hands went to her sides, curving around to her back so he could unclasp her bra. Slowly he pulled the straps down her arms, Abby sitting up so he could slide them from her.

The second his hands were free Gibbs covered her breasts with them, shaping the plump mounds with his fingers and palms. Abby moaned and grabbed onto his wrists, Gibbs' thumbs rolling back and forth over her taut rosy tipped nipples as she settled herself in his lap.

Grinding down on the bulge in his boxers, Abby's back arched at the feel of his hardness rubbing against the aching flesh between her legs. With only her underwear and the thin material of his boxers separating them Abby leaned forward, changing the angle she rubbed against him.

She placed her hands either side of his shoulders and increased the friction between their bodies, instantly causing their breathing to become louder.

"Abbs…" Gibbs growled, gripping her hips "you keep going and I won't last much longer to test the durability of the bed."

When she stopped gyrating against him to try and remove his boxers Gibbs took the opportunity to roll them over. Abby squealed when she found herself underneath him, Gibbs hopping off her to hook a finger in either side of her panties and slowly drag them down her legs.

Gibbs' hungry gaze studied her as she was revealed to him, her underwear dropping to the floor to join the pile of clothing. As he looked at her he slipped off his boxers, his erection freed and hardening even further at the sight of her fully naked body.

His hands ran up the insides of her thighs and Abby raised her knees, her feet perched on the edge of the bed. Lifting her hips off the mattress, Abby panted and struggled to draw in each breath, her heart rate soaring in time with the racing beat between her legs.

"Gibbs…" she moaned, needing him to touch her.

He gave into her pleas, his thumb moving to seek out her clit and rub over it, his other hand continuing the motions on her inner thigh. Abby felt herself get increasingly wet under his ministrations, her scent unmistakable as it filled the room. She was already incredibly turned on and the sight of Gibbs standing at her feet, his swollen and curved hardness framed by her open legs, only served to make her more desperate for her release.

"Guess we better christen the bed then," Gibbs husked, "far be it for me to stand in the way of science."

Abby's grin of triumph morphed into a groan as he bent forward, his mouth hovering over her warm moist flesh for a moment until he pushed his tongue inside her. Abby's hands clutched at his hair, forcing her throbbing core up closer to his face as he delved in further.

"I love science," Abby moaned.

Her eyes fluttered closed when Gibbs focused all his attention on her aching clit. He rolled it, suckled it, every once in a while using his thumb to firmly swipe over the swollen bud.

All Gibbs cared about was making her scream, needing for her to completely come apart under his touch. He teased her, tasted her, his own arousal spiking at the feel of her under his mouth.

When Abby began to writhe even more restlessly Gibbs sped up his caresses, her muscles quivering as her orgasm drew closer. She cried for more, her entreaty echoing through the cabin and spurring him on.

Gibbs devoured her, Abby bucking up and down erratically, her fingers clinging onto his silver hair. Every sensation that rushed through her originated from the pleasure he was creating between her legs, her heart pounding in her ears and breathing coming in hurried ragged gasps.

"Oh…Gibbs…yes…yes…"

Abby's scream hitched on her last word, her hips halting midair when spasms rocketed through her body.

Gibbs continued to slide his tongue gently over her sensitive flesh as Abby's muscles contracted under his mouth, eventually pulling back when her shudders slowed.

"You know what I said about your hands being on me?" Abby gasped.

Gibbs stood up to his full height and grinned at the satisfied smile on her face. "Yeah…"

"Ditto on your mouth…god that tongue…" She sighed and collapsed.

Helping her shuffle around to the middle of the bed, Gibbs laid down beside her, his hand lightly smoothing over her stomach. His body was flush against her side, his erection digging into her hip as he pressed tender kisses over her face, neck and shoulder.

He heard her breathing start to slow, his own catching when Abby wrapped her skilled fingers around him. Gibbs' lips moved away from her face when she started to stroke him, his words escaping on a harsh groan. "You're not so bad with your hands either."

The bed started to shift slightly as he thrust into her hand, but Abby knew the best way to test the sturdiness of the bed was for him to be inside her. And if science was the excuse she was using to be on the receiving end of multiple orgasms then she would gladly use it as justification.

"Hop on top of me," she instructed, removing her hand from him and coercing him between her legs. "Need to feel you move against me."

Gibbs did as he was asked, anxious to feel her slick heat surrounding him. Propping himself above her he rubbed the head of his cock through her folds, nudging against her clit and making Abby gasp before he eased inside her.

Abby trembled as he pushed in, her still recovering body accommodating him as she took in every inch.

She lifted her legs higher up Gibbs' back when he settled against her, taking his face in her hands and pressing her lips to his. Their kiss was slow and gentle as he slipped further inside her.

"I don't think I wanna share this with anyone else," she whispered. "I kinda like it just being you and me."

"Wasn't planning on inviting anybody else in on this," Gibbs teased. "No way I'm sharing you with anyone."

Abby moaned as he started to slowly thrust inside her. "I meant the cabin…I want it to be our dirty little hideaway...and more."

"It'll be whatever you want it to be."

Abby felt her arousal build again as Gibbs described what he'd do to her in their bed. How they could make love whenever they wanted, how he'd make each time memorable, how they had years of catching up to do and this was only the beginning.

As he continued to move in her Abby met his thrusts with her own, clutching on to him like she never intended to let go. Gibbs was unbelievably hot and hard inside her, he felt amazing. And even though they sometimes joked about the amount of sex they had at the cabin, there was nothing that made her feel more complete or more loved than when they were joined like this.

It was about more than the physical release, this was about connecting with Gibbs on every level. As much as he turned her on and she wanted to be at the mercy of all the pleasures he could give her, it was about showing him how much she loved him as well.

"I love you Gibbs," she whispered, bringing his head down to kiss her. "Love you so much."

"Love you too, Abbs."

Kissing her one last time, he lifted his upper body weight off her again so he could make his strokes deeper. Abby hiked her legs further up his back, screaming out in passion as he hit the right spot and picked up speed.

Gibbs clenched the edge of the mattress, his fingers gripping so tightly it started to hurt. But nothing would stop him. As their bodies rocked together in a familiar dance all he cared about was Abby and the feel of her heated skin sliding against his.

Despite Gibbs moving faster and driving into her harder, the bed showed no signs of buckling under the pressure. Abby's rhythmic moans turned into cries of desperation, Gibbs grunting with each forceful plunge.

When Abby's climax slammed through her she didn't try to contain her scream of pleasure, her entire body tensing as Gibbs continued to stroke into her. She held her breath, strained whimpers escaping her lips as she let Gibbs draw out her release with each thrust.

Feeling her fluttering around him was enough to send Gibbs over the edge. With one last snap of his hips he arched over her and groaned Abby's name, spilling inside her.

For several minutes neither of them moved, their limbs heavy but completely satisfied. This was the type of ache Abby craved and she relished in every moment, knowing that it was all because of Gibbs.

Tenderly kissing down the side of her face Gibbs sighed next to her ear, causing a fresh wave of goose bumps to break out over Abby's skin. "I love science too," he murmured, his voice gravelly.

Abby couldn't help but laugh, her legs slowly falling from around him as she lost the battle to keep them locked in place.

Gibbs lifted himself off Abby, collapsing on the bed next to her, his body still hyperaware of her touch as she snuggled up close to him. Sprawling over his front, she threw a leg over his thigh and nestled it between his, her hand spreading out on his chest as it tenderly roamed his sweat slickened skin.

"You know for it to be a thorough experiment we're gonna have to use different positions?" Abby questioned innocently.

Gibbs turned his head, pushing several damp tendrils of hair from her face as gave her a boyish grin. "Something tells me that won't be a problem."

Abby knew at some stage Gibbs would get up and put his clothes back on so he could work on the cabin. And she was okay with that because she got to help him and watch him.

Spending time together like this, alone and with nothing to interrupt them, went beyond anything she had ever allowed herself to hope for. In between the mind blowing sex they could talk and just enjoy being with one another.

Here, Abby got to see Gibbs in a different light, he was still the man she loved at work, but there were so many more layers to him. And it was that which Abby wasn't willing to share with others yet.

She liked the secrecy of the cabin being somewhere that their more primal urges could run wild, but it was the part of Gibbs that was completely unguarded and comfortable here that Abby longed to keep to herself. She'd waited so long to get a glimpse into this side of him, and for once she was going to allow herself to be selfish.

Abby always did her best to put others first, but now her priority was Gibbs and what was best for their relationship. The bed that he'd made for them, that they lay together in, showed how important their future was to Gibbs as well.

Knowing he had as much faith and hope in their life together, that he wanted to fall asleep next to her, and share his body and heart with her was all Abby needed.

The cabin gave them a chance for happiness, the time and space to be who they really were, and the freedom to let go.

The End.
