Title: Tight
By: Serenity
Pairing: Nick/Greg
Summary: Greg helps Nick out. Written for the clothing challenge at live journal.

Greg sniffed as he walked into the locker room, his nostrils tickled by a sharp tang. An overwhelming scent of lemons hung in the air, which could mean only one thing. Someone had been on a decomp case.

Nick was standing in front of his locker, a white towel fastened tightly around his waist, his skin still glistening wet from the shower. Droplets of water ran from his hair, down over his muscled chest and sharp sculpted abs, soaking into the thick fluffy cotton.

"Hey Nick." Greg greeted him after mentally counting off five seconds for an obligatory ogle. "Bad decomp?"

Nick spun round and blushed when he saw Greg watching him. "Oh... hey. Yeah, it was a stinker all right." He sniffed the back of his hand, his nose wrinkled in a cute, endearing way. "Can you still smell it?"

Greg shook his head and smiled. "Nah, I just smelled the lemons and I figured." He hung his jacket up in his own locker and turned to leave Nick to dress in private. After a moments hesitation, Nick shot out a hand and grabbed Greg by the wrist.

"Greg, wait. You wouldn't happen to have any spare clothes I could borrow, do you?" He shifted uncomfortably from one bare foot to the other, biting his lip in embarrassment.

Greg turned and opened his locker again. "Sure I do." He flashed him a megawatt grin. "What happened to your mantra of always having spare clothes for any occasion?" He pulled out a pair of black jeans and a dark red t-shirt and handed them to Nick.

Their hands brushed slightly as he passed the clothes over, and Greg felt a shiver of excitement run through him that was impossible to ignore. If Nick had noticed, he didn't mention it, instead he remained focused on the clothes in his hand.

"Yeah, well, I usually do, but I must have forgotten to bring them today. Talk about bad timing." He tossed the clothes onto the bench and the flush on his cheeks grew deeper. "I don't suppose you have any... underwear." He briefly met Greg's gaze, then went back to studying the clothes intently, like they were going to do something amazing any minute.

Greg shook his head, sucking air in through his closed teeth. "Sorry man, looks like you'll just have to go commando for the rest of the shift." His eyes twinkled with mirth. Feeling suddenly bold, he leaned close to the near naked Texan and whispered conspiratorially in his ear "I won't tell if you don't. It'll be our little secret."

Fighting an almost irresistible urge to smack Nick on the ass, he raised one eyebrow in what he hoped was a suggestive way, smirked, and left the room.

He spent the rest of shift trying not to think about Nick wearing his clothes. If he let his mind wander he knew he ran the risk that he was also going to need to find himself a new pair of jeans from somewhere. Nick had been called out to another crime scene just after the locker room incident, so Greg hadn't had the chance to see how he looked in the hastily borrowed clothes.

The fates soon blessed him though, as Nick's voice could be heard drifting up the corridor towards the evidence room where Greg was sorting through some trash. He was with Grissom, discussing some insects that had been found at the scene.

He saw Grissom walk past the room, his glasses perched at the end of his nose as he looked into the small tub he was holding. Nick made to follow him, but he steered off when he saw Greg and came into the evidence room.

Greg let out a clearly audible gasp when he saw Nick walking towards him. The red t-shirt was strained across his pecs, his sharp nipples evident through the thin cotton. But it was the jeans that really blew his mind. They were so tight on him that the denim looked like it had been spray painted on, his muscular thighs moving and shifting as he walked. From what he could see without staring, they looked pretty damned snug around the crotch too.

Even though Greg had made it his favourite hobby to check Nick out at every opportunity, he never realised how much body mass the older man had over him until now, and just how tight the borrowed clothes would be on him. His hands started trembling, making him drop the piece of trash he was holding. As Nick bent over to retrieve it, Greg was treated to an unrestricted view of his ass, hugged by the tight black fabric, like a peach wrapped in cellophane.

Greg's head began to spin at the sight, knowing that there was nothing between the denim and Nick's hot skin beneath. He swallowed hard and put both hands against the table to steady himself. He tried in vain to fight the hardness developing in his pants, thanking every god he could think of that he was wearing his lab coat, which would hide any tell-tale bulges.

"You feeling alright, G'?" Nick asked as he straightened up again, depositing the trash on the table. A smile danced across his face as Greg nodded dumbly, his throat suddenly dry, his eyes wide like saucers. Nick ran a finger down the side of Greg's face, collecting a bead of sweat. "You're just looking a bit....hot and bothered."

He realised he'd been holding his breath and he exhaled sharply as Nick moved closer. "I'm fine." he stammered, his voice cracking and betraying his lie. Nick leaned in and whispered in his ear, his voice low and seductive, his hot breath making the hair on the back of Greg's neck stand on end.

"Listen, why don't you come back to my place after shift and I can give you your clothes back." His tongue darted out and swiped a hot line over the sensitive spot behind Greg's ear, making him squirm with pleasure. "I won't tell if you don't. It'll be our little secret."

Greg could feel the heat radiating from Nick's body as he moved to stand behind him, still smell the sharp scent of lemons lingering on his skin. To any casual observer who happened to pass the lab, it simply appeared that the two CSI's were deeply engrossed in the trash that lay before them on the table. The reality couldn't have been more different.

Nick pressed his chest against Greg's back, his mouth still close to Greg's ear. "Well?" he murmured. "What do you think?"

Greg's brain had gone on an unscheduled leave of absence, these sudden developments too much for it to process. He remained silent, unwilling to even breathe in case the illusion was shattered and he woke up from yet another vivid Nick dream, hot and panting and wrapped in sticky sheets. So he froze, his senses overwhelmed by the close proximity of his crush.

"Greg?" Nick's voice was more hesitant now, and he took a small step backwards, breaking the physical contact between them. Mistaking Greg's continued silence for an embarrassed disinterest, he put more space between them and began to stammer apologies.

"Oh. Oh, God. Listen, Greg, I'm sorry, I just thought..... I don't know what I was thinking." He stumbled backwards to the door, the evidence table now a barrier between them. "I'm so sorry, man." His face was shadowed by the mortified blush that matched the t-shirt he was wearing, as he bumped awkwardly into the perspex wall of the room in his haste to leave, wildly grabbing for the door behind him. "Do me a favour and forget this ever happened, OK?"

He had slipped through the door and raced down the corridor before Greg was able to comprehend the events that had just taken place. Suddenly his brain chose that moment to form coherent thought and it screamed at him that this wasn't a dream, this was real, and he'd better move his ass and find Nick and try to explain how he felt before he screwed things up completely.

He made a left turn from the lab, running to try and catch up with the Texan, who had disappeared around the corner and into the men's room. He took a deep breath and gently pushed the door open to find Nick leaning against the sink, his reflection in the mirror showing the pain and dismay in his face. His eyes were screwed shut, his brow crumpled in a deep frown.

He squeezed the cold porcelain in his fists, the movements causing the muscles in his back to shift and contract under the skin-tight cotton, and it occurred to Greg that he looked like one of those statues carved out of marble, all hard flesh and sharp angles.

Nick was still unaware that Greg had followed him, and he began muttering softly to himself, so quietly that Greg could barely hear him, but he could pick out the words "idiot" and "never be interested" and "ruined everything."

The walk across the bathroom to reach Nick seemed to take an age, his feet felt like he was treading through sticky cloying mud. Nick became aware of the movement behind him, his eyes snapping open, his gaze landing on Greg's reflection in the mirror.

Without speaking, Greg reached up to Nick's right shoulder and spun him around so they were face to face. They stayed that way for a few seconds, Nick's puzzled face only inches away from his own, their breath coming in quick ragged gasps heating the air between them.

Greg didn't remember either of them moving, but suddenly their lips were pressed together, like magnetic forces had driven them, the kiss causing a million tiny fireworks to explode inside him. Nick parted his lips and Greg slipped his tongue between them, tasting the mouth he had dreamed of so many times.

Nick's lips were soft, his mouth warm and so welcoming that Greg felt like he could get lost in it for hours. He tasted slightly of the lemon's he'd used, and Greg decided that this was his new favourite flavour and he'd never be able to taste it again without remembering this moment.

Nick's tongue joined the union, twisting and duelling with Greg's in a delicious rhythm that made them both whimper in delight. They gave themselves over completely to the sensation, sinking into the kiss.

Greg's hands snaked around Nick's back, running them up and down his spine and then down to cup the firm denim-clad ass, eliciting a deep moan from Nick as he worked to open the buttons on Greg's lab coat, hands moving beneath the shirt to explore his chest.

It was the most intense kiss that Greg had ever experienced, six years of hidden passion finally bursting forth and engulfing them both, spiriting them away to their own private world where nothing mattered but the feel of their hands on each other and the heat of their bodies burning as they shifted to try and be closer, try to crawl into each others skin and become one person.

Greg's head was spinning, his knees threatening to buckle under the weight of Nick surging against him. He stumbled backwards, but Nick had pre-empted this and had gathered him up in strong arms, holding him as tight as humanly possible without crushing the breath from his lungs. He could feel Nick's erection straining through the too-tight jeans, like it was seeking him out. He reached down to free it, desperate to finally touch, but Nick broke the kiss and stopped him.

"Not here, G'." he panted. "We're in a public bathroom at work, and we're gonna end up getting caught." Greg couldn't speak, could only form needy little whimpers as Nick's arms disappeared from around him.

Nick placated him with a quick kiss. "Just figured you don't wanna get fired." His voice was low and throaty, his lips swollen and bruised a deep red. Greg caught sight of his own face in the mirror. His lips matched Nick's, and he had a slight rash from Nick's stubble.

"How long 'til the end of shift?" he asked, adjusting his clothes and buttoning the lab coat over the telling bulge in his own jeans. "Just over an hour." Nick replied, leaning over the sink to splash cold water on his face. "Why, you got plans?"

Greg slipped behind him and ran his hands over the denim globes. "Yeah, I do." He moaned into the back of Nick's neck. "If that offer of coming back to your place still stands."

Every second of that last hour felt like a lifetime to Greg. He spent the majority of it praying that no new leads would come in with Nick's case, forcing him into working overtime. His own case, a missing teenager, was long since wrapped up after the 'victim' had sheepishly come home.

Grissom told him he could head home whenever he wanted, not understanding why an obviously fidgety Greg was still hanging around. Instead of taking him up on the offer, he made his way to the break room for a coffee while he waited for Nick. His mind was a million miles away, replaying every second of that amazing kiss. He threw his jacket on the chair and poured himself a cup of the hot, bitter liquid, checking his watch. "Ten more minutes, that's all." he sighed to himself. "You can do that, right?"

Suddenly he felt the back of his neck tingle, and he turned to find Nick standing in the doorway, watching him intently. "Hey." he nodded to him, trying to keep his face neutral in case anyone else passed the break room. "Have you finished?"

Nick moved to stand in front of him and took the cup from his hand, making sure to 'accidentally' brush his fingers over the back of Greg's hand as he did so, making them both shiver in anticipation of what those fingers might touch later. He took a sip of the strong black coffee and set the cup back on the counter.

"I'm ready.... If you are." He replied, his voice little more than a growl. Greg had just opened his mouth to answer when Warrick strode into the break room and helped himself to some coffee, not realising what he was interrupting.

"Yo, whattup Sanders. Hey, Nicky, I got a major lead in my arson case, I was hoping you might feel like pulling a little overtime to work the evidence with me." He stopped to blow on the surface of the liquid before taking a sip. "I could really use the help."

A look of abject horror passed across Greg's face as he waited for Nick's answer. Nick just smiled and clicked his tongue against his teeth. "Sorry, 'Rick. No can do, I'm outta here."

Warrick rolled his eyes and chuckled. "Hot date?" Nick punched him on the shoulder and unabashedly looked Greg right in the eye. "The hottest. Gorgeous blond." With that, he turned on his heel and left. Greg stood blushing, every cell in his body wanting to rush after Nick and go home with him in the same car, but he knew that was a very bad idea. Warrick was still watching him over the rim of his coffee cup. "What about you, then?"

"What? No! I don't have a hot date.... I mean, I could..... If I wanted....." Greg stuttered, his nerves causing his 'babble-mode' to kick in. Warrick let out a booming laugh. "No, man! I meant do you wanna help me? Good experience for you." Greg shook his head. "I can't. I do have plans actually." He picked up his jacket and flashed Warrick what he hoped was a casual smile.

By the time he'd made it to the parking lot, Nick's SUV was already gone. He jumped into his own car and drove to Nick's place, keeping just the right side of the speed limit. Last thing he needed was to be stopped by the cops and try to explain why he was driving with a hard on so massive that it threatened to obstruct his view of the road.

He pulled up to the house just as Nick was arriving behind him. They both got out of their cars and walked to the door. "What kept you?" Greg asked, bouncing up and down a little with excitement and anticipation. Nick pulled a small bag halfway out of his jacket pocket. "Just had to make a stop at the drug store."

He turned the key in the door and pushed it open, gesturing for Greg to enter first. He followed close behind and had barely shut the door again before Greg was claiming his lips, slamming him up against the wall. "Do you want me, Nicky?" he breathed into the open mouth. Nick ran his hand down the side of Greg's face and gently pushed him back to look into his eyes. "Always."

They kissed again, Nick moving his hands down the younger man's entire body, ending at his thighs. He cupped his hands underneath and pulled him up, Greg wrapping his long legs around his waist. They moved to the bedroom, the contact between their lips never wavering, and Nick was glad that he knew the way to his bedroom with his eyes closed.

Nick sat Greg down gently on the bed and stood back for a moment as he removed his jacket, wanting to drink in every second so he never forgot it. Greg looked nervously up at him, sucking in his bottom lip. "Nick, before we go on.... there's something I need to tell you." Concern flashed across Nick's face and he knelt down until their eyes were level.

Greg played with the stitching on the navy bedspread. "I've never done this before. With a guy, I mean." Nick's features relaxed and he placed a small kiss on Greg's forehead. "Honestly, Greg, neither have I. We're both flying blind here. But I know one thing." he smiled reassuringly at him. "I want this."

Greg visibly relaxed, and grabbed the front of Nick's t-shirt to pull him in for another hot kiss, scrabbling to get the fabric over his head without losing too much contact. Nick made short work of Greg's shirt and they tumbled back onto the bed, kicking off their shoes.

Nick moved his lips to Greg's neck, sucking and biting until the smooth pale flesh was marked. "I've branded you." He murmured softly against the hollow of his collarbone as he moved down to the small nipples, worrying one of them into a hard swollen nub with his teeth, then soothing it with his tongue. Greg's hands gripped the dark hair as he moaned his approval.

Nick blew a puff of cool air across the wet area, goosebumps forming on Greg's skin. "Fuck, Nick." he gasped, arching into the sensation. "That's the plan." Nick growled, mouthing his way down the toned abdomen, his tongue twisting into the small strip of hair under his navel. He unbuttoned the blue jeans and pulled them and the stripy boxers slowly over Greg's slim hips, the young CSI's erection bobbing up to hit his stomach as it was freed.

He tossed the clothing on the floor and went back to kissing the smooth skin before him, breathing in the musky scent of Greg's arousal. He looked up into Greg's eyes, as if asking permission to continue. Greg nodded and Nick took hold of the hard cock, running his hand up and down the shaft in the same motion he used to jerk himself off. The flushed tip was wet with precum and he swiped at it with his tongue, which drew a deep rumbling moan from it's owner.

Spurred on by the reaction, he took the length into his mouth, swirling his wet tongue over the ridge, Greg gasping and gripping his hair almost painfully. He took him as deep as he could without gagging, then slid him all the way out again. He repeated the action, increasing his speed as Greg began to writhe on the bed, white heat flooding his belly as fireflies danced before his eyes. He tried to thrust upwards, but Nick held his hips firmly, maintaining control.

"Nicky!" He gasped. Being hard all day meant he'd easily lost control when he was finally touched. "Nicky, I'm gonna...." he arched into the willing mouth, spilling his hot, sticky seed in several urgent bursts, Nick swallowing it like it was an elixir.

Greg drifted on the high of his orgasm, watching Nick through half closed eyes as he stood up and peeled the oh-so-tight black denim off his body. If Nick in tight clothes was a visual delight, then Nick out of tight clothes was wet dream come true. His body was just the perfect amount of muscular and his skin had a sun kissed appearance that only served to accentuate the toned lines. Greg could barely take his eyes off Nick's long thick swollen penis. For a second he panicked, thinking it would never fit, but lust soon wiped that thought from his brain.

Nick reached down to his jacket, grabbing the bag he'd shown Greg earlier. He pulled out a box of condoms and a small bottle that Greg guessed was lube. He lay back down on the bed and brought their lips together for another searing kiss. "Are you sure you want this?" He asked. Greg nodded, his brown eyes flashing with desire. "I need it."

He snapped open the lid of the bottle and drizzled the liquid over his fingers. Greg's body stiffened when he felt the whisper of Nick's finger swirling over his balls and down towards the tight opening, but the warm mouth kept kissing him until he relaxed enough for Nick to gain entry. After gently working him open, he added another finger, Greg gasping as the tips brushed over his prostate.

Nick pulled out again and ripped open the condom wrapper with his teeth. "I think you're ready." he panted, rolling the rubber down over his thick shaft. He poured some more of the lube on to it as Greg began to roll onto his stomach. Nick put a hand out and stopped him. "No, baby. On your back. I wanna see your face."

He manoeuvred himself so he was between Greg's legs, biting down on the young man's neck to try and distract him from the pain elsewhere. He pushed in, Greg's muscles automatically tensing around him, trapping him in place. Nick looked at his new lover, realising his eyes were screwed tightly shut. "Look at me Greg." he said, his voice soft and tender. Greg slowly opened his eyes. "Do you trust me, Greg?" He nodded, his face flushed and moist with sweat.

"Say it Greg." Nick's voice was insistent now. "Do you trust me not to hurt you?" Greg moved his arms up around Nick's neck and pulled him down for a kiss. "I trust you, Nick. I'm OK, I promise." He relaxed enough for Nick to begin moving, slowly at first. Greg ran his hands down the solid back and grasped the firm ass pumping into him, urging Nick to go faster now that he was used to the sensation. Nick complied and began thrusting harder and deeper.

Greg's cock twitched to life again, growing hard under Nick's stomach as he began to brush that delicious bundle of nerves with each thrust. Their bodies were sticky and slippery with sweat, the bedroom becoming hot and steamy, the air tinged with the smell of sex. Nick's thrusts grew more erratic, hips pumping and jerking wildly, his orgasm imminent. Greg groaned loudly, his own arousal growing uncontrollably. Nick grabbed his hardness and stroked him in time with his thrusting, keeping eye contact continuously.

"Fuck! Greg!" Nick called out, his voice strangled. He closed his eyes and threw his head back, his release powerful and surging. Hearing Nick call his name like that was enough to tip Greg over the edge for a second time and he shot all over Nick's chest and abdomen with a grunt.

Nick pulled out gently and tossed the condom into the trash can beside his bed. Greg lay still, wondering what Nick expected of him now. Did he want Greg to leave? He decided no, when Nick flopped down beside him, wrapping the bedspread around them like pigs in a blanket.

"How do you feel?" Nick asked him, his voice gentle and soothing. He nuzzled into the pale neck, breathing in the unique way Greg smelled. "A little stunned." Greg replied honestly. "But good. Really good." He turned so that every inch of their bodies were pressed together. Sharing soft, sweet kisses, they both sighed with complete satisfaction.

"You know, I thought I'd totally screwed up our friendship today." Nick's voice wavered, and Greg noticed that his eyes were shining slightly.

"I'm sorry about that." Greg kissed him lightly on the nose. "You just fried my brain, standing close to me like that in those jeans. I didn't know what the hell was going on. I thought I was dreaming again."

"Again?" Nick sat up on one elbow and looked down at him. "You've dreamed about me before?"

Greg blushed slightly. "Maybe, once or twice..... OK, a lot. But you got that out of me while I was naked and vulnerable. It'll never stand up in court."

A smile that could only be described as smug flashed across Nick's face. "I never thought you'd be interested in me, I mean, being friends was great but...." he trailed off. "I never once thought that you might be gay, I know you flirt with everyone, but I just figured that was your personality."

Greg turned and lay on his stomach, propping himself up on his elbows. "I don't think I am gay. I've never been attracted to men, only women. I wouldn't have even classed myself as bisexual until we met, but.... It's you, you know? You make me feel like this." He reached across and twisted his fingers through his lovers, intertwining them. "I think I'm just Nicksexual."

Nick laughed and pulled him in for a breath-stealing bear hug. "I can live with that. I feel the same way, I never thought about guys until I met you. You just do something to me that I can't explain, and I was never going to do anything about it. But when you made that commando remark, the way you looked at me...." He released Greg, letting him drop back down onto the bed. "I couldn't get it out of my head the whole shift. So, this.... us.... it's not just going to be a one time thing, is it?"

"Not if I have anything to do about it." Greg grinned in that heart stopping way, his tired chocolate brown eyes full of love. "Oh, and another thing." he shifted until he could reach around and grab Nick's backside, closing his eyes drowsily. "You should hang on to those jeans. They definitely look better on you."

Nick kissed him one last time before they fell asleep in each others arms, feeling complete at last.
