Summary: Sara had no idea what she was talking about.

***

It started off innocently enough. They were talking about the case, eating at the place where the three of them always eat – Sara carping about tradition and marriage, Nick unknowingly repeating Sara and defending tradition, and Greg wondering why they were questioning their choice of eatery.

But it really started when Nick said the word love.

Yet, it wasn't what he said because even though they didn't say it often, the words I love you had already circulated more than once or twice. But it was the fact that he said it while staring at Greg, an endearing look on his face, emphasising that Texan drawl in his voice and smiling that dopey smile – the one that never failed to make Greg gush even when Nick had a piece of bacon hanging off his lip.

It was as soon as the waitress left that she said it.

That's when Sara said they acted like an old married couple and Greg didn't truly know if he felt bothered when Nick didn't try to deny it. Sure, they lived together, were definitely beyond the status of friends with benefits, practically did the public declaration aspect even though they didn't have the legal documentation, but maybe it was the old in old married couple that made him think about it and possibly feel bothered by it.

But Nick was quick to reassure him that old married couples probably didn't share their stamina.

He was struggling with the keys, trying to open the door, but Greg couldn't help but be distracted by Nick, who was in the process of plastering his body to him while gently nibbling on his earlobe. He knew it was the right key in his hand, he'd felt it, memorised it, and had a spare somewhere he couldn't remember. But it just wouldn't go in the lock, wouldn't fit like Nick was trying to do – impossibly close, rubbing denim clad cock eagerly into his ass, lips moving from Greg's ear, sucking the back of his neck and sure to leave a mark Warrick would tease him about later.

He felt Nick's warm breath against his skin, the smell of Nick invading his nostrils and he wasn't sure what Nick was complaining about earlier because he didn't really mind it that much – even if it was preventing them from getting into their house.

But it seemed Nick couldn't wait anymore, breath haggard as he urged Greg against the door, one hand holding the younger man by the hip and the other taking the key and putting it into the lock.

Greg took that as his cue to open the door, Nick still against him, hand still firmly gripping his hips and pushing Greg through the threshold. He turned Greg around while he closed the door, propping the other man's chest against it. His arm went around Greg's waist as he reached to lock the door, satisfied at audible click, mouth attacking the back of Greg's neck with a new fervour and leaving a soft bruise.

Nick rolled his hips into Greg, enjoying the short gasps elicited by the younger man with each small movement, holding him close, involuntarily loosening his grip while he kicked his shoes off.

But it was all Greg needed as he turned to face Nick, grabbing the older man's face, feeling a trail of saliva on his neck as he crushed his lips to Nick, pushing him toward the couch and landing on top of him.

He took a hold of Nick's shoulders, straddling the other man and trying figure out how to get his jacket off without letting go of Nick because it would mean moving his hands off Nick. His hips were moving on their own accord, fuelled by something beyond his knowledge as he began to grind against Nick's groin, moving slowly and creating a burning friction between denim, feeling his cock constricted, confined against his jeans.

Nick arched up; trying to pace himself because they were moving ridiculously slow and he wasn't sure how long Greg could use his weight to keep him down. He hit his head against the armrest of the couch, moving it to the side as Greg made those soft little noises, the ones that came from the back of his throat that stirred something in the bottom of Nick's stomach. He was trying to wait because he promised Greg he would wait it out and take his time, but he just couldn't do it right now.

He wasn't in the mood.

Especially not after being holed up in the station for more than fourteen hours.

Greg could tell Nick was getting anxious, impatient and too eager for his own good, but he kept his hands steady on the other man's shoulders, using his weight as a counter measure in order to hold Nick in place. Then Nick grabbed his arms, arching up and taking Greg by surprise, causing him to tumble. And he was falling over with a small yelp and finding Nick pressed flush against him, whispering into his neck. "You all right?" His voice was ragged, rough, and full of concern Greg knew was in Nick's eyes.

And he wanted to answer, was going to answer until Nick answered for him, his hand sliding in between their bodies and grabbing the bulge in Greg's jeans. His body jerked upward, sliding against the carpet and for once Greg was glad he had his jacket on, imagining the carpet burn he didn't want.

Nick loosened his grip on Greg, fingers playing with the button of Greg's jeans as he moved his body down, resting his face in between Greg's thighs and rubbing his cheek against the soft denim. Greg's whinges were in the background; music to his ears as he pulled down the zipper, grabbed the waistband of Greg's pants and tugged it down slowly.

Greg lolled his head back, wondering why Nick was suddenly taking his time as he lifted his hips; helping Nick take his jeans off. He made the attempt to remove his jacket, struggling out of the sleeves and throwing it somewhere in the room as the other man's hand was on Greg's thigh, fingers barely touching, slowly dancing upon it.

Nick looked up at Greg through lowered eyes, watching Greg's head fall back, exposing his neck and tempting Nick, enticing Nick and he couldn't stop from attacking it again.

"Ugh...Nicky..." Greg moaned pitifully. Nick was sprawled on his body once more, holding his arms down as he sucked on the other side of his neck, hungrily and greedily while crushing their groins together. "You and my neck..." He gasped when his cock brushed against Nick's pants, Greg's underwear a thin and obstructive barrier as he felt a familiar wetness between them and Nick's body becoming limp on top of him.

Nick didn't even make a grunt and Greg would have been surprised if he didn't know better, if he didn't expect more and if he didn't notice that Nick was still hard and his cock was pressing into Greg's thigh.

Because then Nick raised his head to look down at him, a lecherous grin on his face before he leaned in to capture Greg's lips, sucking on his bottom lip, holding it in his lips and caressing it with his tongue – murmuring into Greg's mouth. "Where's the lube?" he asked, thinking about the condom in his pocket.

"In...in God." Greg took Nick's hair in his hands, running his fingers through Nick's scalp, grateful he had something to hold on to when Nick began thrusting into him again, forcing his body into the carpet. And Greg was almost afraid Nick would cause him to make a hole in the floor or make him fall through it. At the rate Nick's hips were pounding into him, Greg wasn't sure if it was safe not to be concerned. "...in the car."

"You didn't bring it?" Nick hissed as Greg's hands moved down his neck, sliding down his back, grabbing the fabric of Nick's shirt and trying to pull Nick closer.

"I was thinking about something else," Greg growled as he rolled them over, his tone almost admonishing as Nick seemed to conveniently forget he was the one who dragged Greg out of the car, almost wouldn't let him lock the door in his haste to get in the house.

"What about...what about the bathroom?" Nick asked, licking his lips. Greg's hands were on his shirt, moving up and down and distressing the fabric.

"Guest bathroom," Greg answered, his hands moving under Nick's shirt, trying to push it above the other man's head.

Nick didn't even bother to wonder why they still had lube in the guest bathroom. He thought he cleaned the last of it out but he wasn't going to argue because Greg's mouth was now on his skin, lightly touching his navel, following the fine hairs on his stomach, tracing in between his nipples and he was trying not to give into the urge to rush things, but he was too far gone to care at this point.

Greg should have known when Nick became still, no longer bucking beneath him – that should have been his first clue. But like Nick told him and like he already knew, he didn't think well during these moments – couldn't function well. Greg knew that even though he didn't, the only reason Nick thought it was cute was because he always had the advantage and Greg never expected things like being pulled off the floor, weight completely on Nick, and forgetting whatever it was that they were doing.

Nick was taking off Greg's shirt, inwardly smirking when Greg lifted his arms, trying to latch on to Nick's mouth through a foggy mind, ending up kissing the thin material of the shirt. He seized Greg's lips, pushing the young man forward, making it easy on them both as he manoeuvred them into the bathroom, kicking the door open with his foot and turning the light on with his elbow.

Greg shivered when Nick's hands attached themselves to his sides, rubbing against his skin and pushing him against the sink. He took his shoes off against the edge of the cabinet, feeling lighter when they fell on tiled floor. He heard Nick kick them side but it moved to the back of his mind as Nick was pushing him closer and closer until Greg felt his feet leaving the floor. His toes were curling as he sat on top of the sink, his bare back brushing against the mirror and skin tingling against the cool surface. And Nick was in between his legs, holding Greg still as he rubbed against the younger man.

Nick lowered his head onto Greg's chest, taking one hand off the other man to open a drawer, fingers searching frantically for a small bottle distractedly, not paying attention to his slackened grip on Greg's side.

Feeling Nick's hold loosen, Greg took the chance to put all of his weight upon Nick, forcing the other man to take a step back as he pushed him out of the bathroom and toward the kitchen.

Nick frowned when he found himself being forced out of the bathroom. The lights were still on and that was electricity being wasted at ten in the morning. But the frown was only temporarily as he found himself with a mouthful of Greg and quickly forgetting about the electric bill.

"Oh, god." Greg pushed Nick past a counter, rushing by pots and pans and making them crash loudly to the floor. "Can't...bed too far..." Greg tried to move Nick toward the kitchen table, wanting no more than to situate them on a flat surface. He couldn't wait to make it into their room, didn't think he'd be coherent enough even if they did make it to the bed.

Nick moaned, the edge of the table digging into the back of his legs before he pushed Greg away, forcing the younger man against the wall beside the refrigerator. "Not the..."

"The table's...and I...." Greg tried speaking, finding it hard to focus when Nick began pressing into him, one hand creeping down his bare thigh, resting under his knee.

Nick gritted his teeth, raising his hips against Greg. They were not having sex on the kitchen, no matter how much he wanted to. They ate in the kitchen, had guests in the kitchen...it was bad enough they already had sex in the living room...and he ended up cleaning their semen off the wall. But Nick tried to clear his head from that time because thoughts of pounding into Greg against the wall weren't really helping his resolve – especially since his jeans were the only thing preventing Nick from doing so again right now.

But no matter how much Greg mewled and made those noises or however tempting he looked with his neck arched beatifically and face flushed, they were not having sex in the kitchen.

Greg's bit his lip, preventing himself from crying out when Nick pinned his leg against the wall, twisting as he thrust into Greg. He was hard, so achingly hard that it took every ounce of effort not to scream when the older man's hand disappeared into his underwear, grabbing his ass, moving the side of his hand in between his cleft. Nick was toying with him, painfully squeezing and kneading his cheek as his motions forced Greg up and down the wall.

Nick grunted when Greg hung his arms around his neck, pulling Nick closer and holding on to his hair – running his hands through it, over it, and pulling so hard that Nick had to close his eyes to bare the pain.

"Nick...Nicky...I."

"Not..."

Greg gasped, eyes widened when Nick made a particularly sharp thrust.

"In..."

Panting harshly, he wrapped his leg around Nick's waist.

"The..."

He tightened his arms around Nick's neck, taking a sharp inhale.

"Kitchen." Nick buried his face into Greg's shoulder, desperately trying to refrain from giving in. He was so close, so incredibly close that he almost wanted to rethink his rules about where they were allowed to have sex in the house.

Greg growled angrily...Nick and his stupid rules. But if Nick didn't want to do it in the kitchen, that was fine – just fine. But he didn't want to wait any longer, couldn't wait any longer as he used the wall as leverage to push off.

Nick almost fell back when he Greg jumped on him, not giving him time to react and covering Nick's lips. He found himself moving backward and praying he wouldn't fall. He tried to keep up with Greg's pace, holding on tightly to the waistband of Greg's underwear, pulling as much as the younger man was pushing.

Greg used his height to his advantage; arms still around Nick's shoulders and lip-locked with the older man as he pushed Nick toward the bedroom, their momentum opening the door and carrying them to the bed.

Nick grunted when Greg fell on top him, the springs of the bed squeaking beneath their weight. He moaned when Greg removed his lips, nuzzling his head in Nick's chest. He wrapped his arm around Greg's waist, his other hand on Greg's head, fingering the now damp hair curling at the nape of Greg's neck. Feet flat on the sheets, he lifted his knees as Greg began to wriggle in between his legs, sharply inhaling when Greg's mouth found its way to one of Nick's nipples, tongue circling it.

Greg smiled when he felt Nick clutch his hair, knowing what he was doing to the older man. He reached behind his waist, taking from Nick's hand the bottle of lube that was digging into his back. It was fun for him – teasing Nick – but he enjoyed it while he could because he didn't know how long until the other man could hold out.

Nick sighed impatiently, inwardly cursing Greg for being a such tease as the younger man made his way to Nick's stomach, lips never breaking away from his skin. He lifted his head, looking down when the younger man's mouth was nearly at his pelvis.

Greg looked up at Nick from beneath his eyelashes, smirking as he placed a kiss on Nick's navel, using his hands to unbutton Nick's jeans. He pressed his face into Nick's stomach, the hairs tickling his skin as he slowly pulled down the zipper.

Nick found himself loosen his grip on Greg's hair, fighting to keep himself still as one of Greg's hands found its way into his briefs, fingers cupping his balls, completely neglecting his cock. He moved his head to the side, absently reaching to a table beside the bed – forgetting the condom in his jeans as he blindly searched through the drawer for one, groaning when Greg pulled away.

Greg opened the bottle of lube with one hand, his other holding the waistbands of Nick's jeans and underwear, pulling them both down when Nick lifted his hips.

Nick hurriedly kicked off his jeans, the sound of them falling to the floor neglected when he heard Greg moan. The other man was now sitting up, body curved outward, resting his weight on one hand and fingering himself with the other. Nick saw the sheen on Greg's body, reflected in the dim light peeking through the blinds. He wanted to reach up, bring Greg down from his self-induced high – wanted to be the reason that Greg made those noises.

Greg let out a small cry, his hair damp and falling into his eyes as jumped at his own touch, cock bouncing against his stomach. He bit the inside of his cheek, quivering when he felt his finger hit prostrate.

Nick looked up eagerly at the wanton figure above him, ripping opening the condom as he continued to watch Greg writhe, the younger man closing his eyes and seemingly lost in the sensation of his own ministrations.

Greg was forced to open his eyes when Nick took his hand away, lubrication sliding down his fingers as Nick pulled him forward, the other man's hands around Greg's waist, sliding down to massage his cheeks.

Nick moaned when the Greg placed himself on Nick's cock, hands resting on either side of Nick as he began rubbing himself against it – moving slowly and only further enforcing Nick's notion that Greg was nothing more than a damn tease as he almost felt his cock breach Greg, moving in between his ass and the younger man pulling away too soon.

Greg felt the perspiration drip from his face, Nick moving up against him as he tried to hold on to some semblance of coherency. He moved away from Nick's cock, griping it tightly an attempt to keep Nick from distracting him. Leaning over, panting and almost out of breath, he repositioned himself, somewhat grateful when Nick's hands helped to guide him.

Nick groaned, keeping his body pressed against the bed when he felt a slight pressure at the tip of his cock. He kept his hands steady, careful not to rush Greg and fighting the urge to thrust upward. Still cupping Greg's cheeks, he didn't think he'd ever get tired of this feeling. Even after four years, there was nothing more he wanted than to push into Greg – be surrounded by that tight, familiar heat.

Old married couple, his ass.

Greg scrunched his face as he slowly lowered himself, gasping when Nick's cock was halfway in. He was resting on his knees, Nick's legs between him as the other man moved his hands – stroking Greg's thighs and trying to calm him.

Clenching his muscles, he began to take in more of Nick's cock; slightly beginning to rock forward when Nick started making those deep, guttural noises from the back of his throat – urging Greg to push Nick further in. He sighed when felt Nick fully inside of him, closing his eyes and taking a deep breath as he tried to relax, hands tightly gripping the sheets besides Nick.

Nick stared at Greg, watching and waiting for the younger man to adjust as he felt the sheets rustle around him. He had no problems with waiting, never where it concerned the younger man, but then Greg lifted himself up and slammed down hard against Nick.

Greg knew he took the older man by surprise when he heard Nick's groan. He released his hold on the sheets, seizing Nick's wrists, moving Nick's arms above his head and leaning forward as he raised himself up again – feeling the tip of Nick's cock before tightening his muscles and pushing back down.

For once, Nick didn't mind that Greg was holding him down. Right now, he even encouraged it because he was too preoccupied with the feeling of his cock in Greg's ass. And even though the feeling was already overwhelming, he wanted more. He craved more when Greg leaned further, closer and closer until his head is lowered and almost touching Nick's shoulder.

And then Nick remembered that Greg is holding his arms above his head, wishing that Greg was close enough so that his lips could roam over Greg's skin. But the man above him seemed to sense his urgency and Nick found his thoughts interrupted and mouth engaged in a kiss.

Breathing heavily, Greg broke off from the kiss, lips enticingly pink and swollen as he looked down at Nick. He rested his head in the crook of Nick's neck, pinching the skin in between his lips as he pushed down once more.

Nick felt the hold on his wrists loosen, Greg still on his cock and the younger man slowly gyrating his hips. Greg's was still hard against his stomach, murmuring something unintelligible in Nick's neck. He moved his hands from above his head, arms moving to encircle Greg as he made a small thrust into the younger man.

Greg felt his body jolt, breath hitching when Nick pushed into him for a second time. He didn't the forget the fact that he was still hard or the fact that Nick was still hard, but all he could comprehend was the fact that Nick was hitting that spot right there, moving faster and faster until Greg wasn't sure if he was moving up or down or even some way in between.

Nick strengthened his hold around Greg, hearing the other man babble into his skin. But as much as he enjoyed one of the few instances where he could actually make Greg incoherent, he wasn't in the right mind to fully enjoy it.

Greg's eyes widened in surprise; unintentionally biting Nick's shoulder when the other man suddenly sat up and held Greg on his lap. His mouth was captured in a kiss, muffling any protest he had as Nick rolled them over, pushing Greg down on the bed.

Nick ignored the small pain on his shoulder, wasting no time as he repositioned himself over Greg, going in slowly and not hesitating to quicken the pace, feeling Greg's long legs encircle his waist and crossing behind his back – pulling him further into Greg.

Greg rolled his eyes back, arms holding onto Nick as he was taken over by the array of emotion, he vaguely heard the sound of the headboard banging against the wall, some part of his mind wondering if furniture marks would be easy to clean, too, but not really because Nick was leaning down, mouth sucking on his ear, and Greg wasn't sure if he was screaming or not. And then he decided didn't care because he could only concentrate on the feeling of Nick ramming into him like there was no tomorrow.

Nick continued to move, not sure if he would ever reach the point where he'd be able to stop. Because it seemed that each time he thrust into to Greg, felt the other man's muscles clench around his cock, it never seemed to be enough. Even when Greg's fingers grazed his scalp, when he felt the other man's hard cock rubbing against his stomach, heard Greg yelling out his name, head thrown back in ecstasy like some kind of porn star – not that he would ever tell Greg that – he still couldn't seem to get enough.

He was teetering on the edge and painfully waiting to let go.

Greg squeezed his legs against Nick's back, compelling the other man to move faster, push harder, anything as he grabbed a handful of the other man's hair. His head was bobbling up and down and he didn't care if Nick still thought he looked like a porn star when he did that because he was on the brink of something and it felt too good to worry about how he looked.

Nick grabbed Greg's sides with enough force to leave a mark, but he'd apologise later because he was close, so close and light was appearing in the back of his eyes as he took one last thrust, angling himself into Greg, and praying that the condom didn't break when he fell on top of Greg.

And he sighed deeply, trying to catch his breath in the brief silence that followed; arms by his side and resting languidly on the bed.

"God..." Greg whispered as he lightly fingered Nick's hair. He was too tired to move, shocked he could still feel parts of his body and hoped he didn't have to do anything that involved sitting for work. Nick was flaccid inside him; the older man's semen trailing down his thighs...his own semen trapped in between their bodies. Not to mention that Nick was squishing him. Greg would normally be complaining about it, but under these...extenuating circumstances, if he had to pick how he'd go out in life, he wouldn't mind this at all.

"Yeah..." Nick replied softly, resting on Greg's chest and listening to his quick breaths as his head moved softly. His body was completely lax and his weight was fully settled on the younger man, but even though he knew Greg didn't like it, he couldn't move.

Not that he wanted to, anyway.

"Told you...old married couples don't do this."

"Then do me a favour, Nicky..."

"As long as I don't have to...I don't have to move."

"Never ask me to marry you."
