@&@&@&@&@&@


Nick thought he was going crazy. That had to be the only explanation. No other reason seemed to fit why he thought Warrick was flirting with him. Constantly.

Fortunately, evidence was stacking up on his sanity's side. Little touches on his wrist, one of his hot spots, a broad hand against the small of his back. Brushes against his side, intermixed with 'accidental' full body collisions, too many times to be by mistake. Unless Rick had lost all hand-eye coordination and his feet had grown two sizes too big.

And then there were the other touches, the ones they always shared. Like an arm slung around the shoulders, the thumps to the stomach and back, even the deliberate shoulder bumps when they passed each other by. They were the same, but Nick still felt something was different. It was like he was playing a game when all of a sudden the rules had changed. And he was the last to know.

He did his best to ignore the feeling and carry on the same by hanging out after work to share an occasional breakfast, or to Rick's place to watch daytime talk shows and court TV. They still bickered like an old married couple, and the banter was strong as usual. Only now, every little touch set off a little flip in his belly. One that started the day he found Warrick tied up on a table.

"Hey, man. We still on for tonight?" Warrick said behind him, a breath of warm air caressing his ear. Nick turned to hide a shiver and grinned, if a bit strained, at the good-looking man. And if the sparkle in Rick's eye meant he was deliberately teasing him, or flirting for that matter, he might have throttled him then and there.

"Yeah. It's not everyday we get told to take a vacation. You bet I'll be there."

Warrick smiled sweetly, a flash of his dimple causing Nick to break out in a sweat.

"Good. Don't forget, 7:30. The game is on at 8:00," Warrick said as he turned to his locker and began stripping. Nick swallowed and then clapped his hands together, too loudly in his ears, and backed out.

"You bet, man. I'll, ah, catch ya later," Nick said and was out the door and to his car, arriving faster than he thought. Resting his head against the SUV, he sighed and banged his head twice. It made his head hurt, but it didn't erase the sight of Warrick slowly sliding a tight black t-shirt out of his ass-hugging chinos. The more he thought about it, the more uncomfortable his own pants were getting.

"He has to know what he's doing to me," Nick muttered to himself, subtly adjusting himself before climbing into the drivers seat. Putting his keys into the ignition he hummed when the car smoothly turned over. Turning on the heat against the chill of morning dew, he sat back in his seat as something niggled in the back of his mind.

"He has to know..." he said again, slowly, drawing it out, running it through his mind. Rick had to know what he was doing. The man wasn't ignorant in the least, and Nick knew he had a couple of bi friends, him included.

Nick still remembered when his own bisexuality had come out one drunken night at a bar, and Warrick hadn't even blinked. He had spilled all about his repressed sexuality in Texas, his dry streak with, well, anyone, for some time. And how good it was to be able to just *acknowledge* his preferences when he moved to Las Vegas. Even if he didn't go crazy and hook up with people left and right. He was a bit of a homebody, and he liked that lifestyle just fine.

The next day he was uncomfortable, but Rick had let him know he would never say a word unless he approved, and that nothing would change between them. And he meant it, because their relationship was as steady as it had always been, even closer. Rick was so supportive about it, Nick knew he had found a real confidante, a close friend he could count on.

But, Rick never said anything about his own preferences. Now something was going on, and Nick was getting a feeling that it had to do with his confession...And last week in that lab. He was pretty sure he hid his reaction, but Rick was an observant guy.

"Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth," he murmured. Doyle had a good point.

Chuckling, Nick shook his head in amusement. Weeks of torture when the man could have just said something. Or maybe Rick thought he had to seduce him. Though, if he had eyes, he had to have figured out that Nick was attracted to him by now.

It was funny that it took this long for him to figure out what was going on. But, now Nick was on to him. And once Nick was on a case, he liked to get his man.

Putting the car in reverse he slung an arm over the passenger headrest and bared his teeth.

"Game on, Ricky..."

Warrick darted one last look around, and found everything ready. The food was heating in the oven so they could eat dinner, snacks were in front of the TV, and desert was in the fridge and freezer. He thought candles would be too much, a dead giveaway, so he decided to just dim the lights after they got comfortable. He didn't have a lot of practice seducing men, but Nick was worth the effort.

There was a knock, and Warrick checked himself out one last time in the mirror by the door, smoothing over his green polo shirt and dark jeans. Opening the door, his eyes lit up when they landed on Nick, a tight, clean white sleeveless t-shirt and jeans with sunglasses making him look sexy as hell.

Holding up a six pack he grinned, that warm, sweet smile that Warrick felt down in his knees.

"Hey Rick. I brought the beer."

"Hey man, come on in," Warrick said, carefully stepping close to the side so that Nick had to squeeze by. He glanced up and thought he saw a smirk, but it was gone before he could really tell.

"Smells good. What are we eating?" Nick asked as he set the cold beer down. Chips and dips were scattered on the table in front of Rick's big screen, one of the reasons Nick loved coming over, and the pre-game show was on.

"Some Buffalo wings, greens, and potato salad," Warrick said, grinning when Nick's stomach growled loudly.

"Man, when can we eat?"

"Soon, soon. Sit down, take a load off." Nick sat down on Rick's plush couch, the kind that you don't want to get out of, and watched as he walked into the kitchen. Coming back with plates and an ice bucket, he put the beers in to keep them cold. As Nick leaned forward and grabbed the remote, he couldn't help but check out Rick's ass when he bent over to get a runaway ice cube.

Smiling to himself, he took the plate Rick handed to him and filled it up with assorted chips, and mixed the nacho cheese dip and salsa together on his plate. Warrick sat next to him, his own plate quickly filling up, and leaned back to watch the hosts go on about the players. Nick finished mixing his dip and cleared his throat, knowing it would draw Warrick's attention. Bringing his hand up, he licked up and around his messy fingers before sliding them in all the way, and letting go with a wet pop. Glancing over, he raised his eyebrows at Warrick, who swallowed with some difficulty before turning back to the TV.

Nick grinned and swirled a tortilla through the dip. Ready for round two, he reached down and grabbed a beer. Popping the top off he leaned his head back and took several swallows. Seeing Rick looking at him in the corner of his eye, he mmm'd loudly as the cold, bitter liquid splashed down his throat. Putting the beer down he wiped at a small trickle that escaped off of his jaw, and licked his fingers. Warrick made a little noise before suddenly jumping up and mumbling something about food. Nick nodded, holding in a quiet chuckle until the tall man was out of earshot. He could finally get some of his own back after two weeks of torture. This was going to be a lot of fun.

Warrick quickly walked into the kitchen and grabbed a bottle of water out of the fridge. Pushing it in his pants, he gritted his teeth as the coldness worked on his throbbing erection. He knew Nick was hot, but damn, the man was driving him crazy! It was only half-time and he thought he'd bust just watching him drink the beer. If he hadn't walked out just then he might have just grabbed Nick and went at it on the couch.

Sighing, he put the water bottle into the freezer just in case, and pulled out the food. He had almost forgot about dinner, his attention solely on the stimulating presence in his place. The wings and collards were pulled from the oven and, getting the potato salad out of the refrigerator, he placed them all on the counter.

"Hey, Nick! Dinner's ready," he called over his shoulder, as he put out silverware and plates. Grabbing a couple of spoons, and some tongs for the food, he didn't hear Nick sneak up behind him.

"Looks great Rick," Nick said, head peeking over his shoulder. Warrick jumped at his closeness and froze when Nick boldly put his hands on his waist.

"You okay?" Nick asked with an innocence they both knew was false. Shaking his head, Warrick, turned at the waist to look at the man behind him, raising an eyebrow like a dare. Nick just grinned at him a touch of evil dancing in his eyes.

"Yeah, just fine," Warrick said, forcing himself to remain calm. It wouldn't do to just grab Nick, even if he was close enough to feel body heat all along his back. He wanted to ease Nick into the idea of them together, but it was becoming harder to keep control. Turning back around, he carefully put the utensils down before he dropped them.

A shudder escaped him when Nick leaned against his back, and inhaled. Heavily. Right against his neck.

"Mmm. Yep, sure does smell good."

'Or on second thought,' Warrick thought, 'control is overrated.'

"Well I hope it tastes just as good. Help yourself man," Warrick said, his voice steady, if a little deeper than usual.

"Don't mind if I do," Nick murmured. Leaning in, he wrapped an arm around Rick's narrow waist, and kissed just below his right ear, and up to suck on the lobe. Warrick sighed and tilted his head back as Nick continued up to mouth at his jaw. Sucking until Rick began to stir, he tongued his ear, in and out until Rick moaned and pressed his ass back against his hips.

"Who'd you think you were fooling?" Nick whispered in Rick's reddened ear, and kissed it once before letting him go and stepping back. An arm shot out to the small of his back when he swayed, but Rick got his limbs to solidify and hold him up.

"Hey, I didn't think I was fooling you about anything. I just...wanted to take it slow," Warrick said, his back bent over the counter as he leaned on his hands to steady himself.

"Yeah, and that's by not once mentioning you were gay or bi?" Warrick turned around and leaned against the counter as he watched Nick tap his foot on the tiled floor.

"Come on, Nick, all those parties we went to? How do you think I knew all those people?" Warrick said, an arm waving in the air between them.

"How was I supposed to know? They could've been friends of a friend. I thought you were just trying to find me a boyfriend or something."

"I guess I should have known you'd have to be hit over the head to get it. Especially after that time you asked me how I was so 'comfortable' dancing with those guys. It never occurred to you that I was just like you?"

"Well, no. I guess not." They stared at each other for a long moment, before Warrick cracked a grin. Nick snorted and then they both laughed good and hard.

"Yeah, okay, sometimes I can be a little slow, but give me some slack man, you can be kind of hard to read," Nick said, and reached out to grab Rick's hand, and tug him close.

"Next time I'll try to be more obvious," Warrick said as their arms wrapped around each other, holding on tight.

"So what's next?" Rick asked as they grew comfortable and warm in each others arms. Nick's stomach growling interrupted the moment, as they both grinned in amusement.

"Well I guess that answers that," Warrick said, and bumped his hip against Nick's, before stepping away. Turning to the counter he started to pile the still warm food on his plate. Nick grabbed a plate to do the same, letting their arms brush and occasionally bumped his hip against his...well boyfriend he supposed. The thought gave him a little thrill and he couldn't help but chuckle and whistle a little when Rick glanced at him in question.

"I've got a treat for dessert, Nick."

Nick's lip curled in a leer, his eyes dancing at the thought of 'dessert'. One look at him and Warrick laughed outright.

"I mean real dessert, so get your mind out of the gutter."

"Did you bake something? One of your grandma's recipes? Hey, you think you can get her to bake me her famous brownies?" Nick said, the thought of her warm, gooey brownies making his face light up like a kid on Christmas morning.

"Way ahead of you Nicky," Warrick said with a chuckle, enjoying the broad grin that spread over his face. Moving around the counter, he walked into the livingroom and grabbed two trays before sitting down. Opening one up he pushed it at Nick, who placed his food down and settled in.

"No kidding?! You made some?"

"Nah, she sent me some last week. I just store it in the freezer and heat it up when I want some. Since I know you like them so much, I saved some."

"Rick, where's the love, man? You've been keeping the brownies for yourself all this time? What happened to bringing some to work and sharing?" Nick said, a solemn look crossing his face, a hand pressed against his chest.

Warrick snorted, and took a swig of his beer.

"Be glad I saved you some at all. I know you would've gone through my supply once you knew I had it."

They sat in companionable silence, yells and shouts occasionally breaking it as the game wore on. Chatting through the commercials, soon they were done with dinner. Warrick heated up the brownies, and put a heaping spoonful of butter pecan ice cream, Nick's favorite, on both bowl fulls.

During a commercial, Warrick took their empty, licked clean bowls into the kitchen and started to wash the dishes. He was the kind of person where if it didn't get done, it would sit there. He heard Nick puttering around in the livingroom and looked up as he came in with the snack bowls and dip. Two remaining beers and the last of the dip were put in the fridge and the leftover chips into a bag. Nick wandered back into the livingroom when Warrick turned down his help, and was quickly done the dishes. Wiping his hands on the dishtowel, he turned off the lights and the main lamp before settling back into his seat as the game was winding down to an end.

Sated, he couldn't help but stretch out a little, his legs widening as he slid down the couch. When his leg bumped Nick's, he started to sit up, but a hand on his arm kept him still. Looking over at his friend, he saw Nick smile lazily and reached over to pat his stomach.

"Relax man. And thanks, this was a good idea."

"Yeah, it was. I don't think we're going to win this game," Warrick said sighing when the scores flashed over the screen.

"I don't know, I think this game was a success," Nick said, his knee pressing against his thigh. Warrick looked over, and his eyes widened slightly at what he saw. Nick was staring at him intently, eyes dark and heavy-lidded as the glow from the TV made them glint. Fingers made pale in the light brushed over his cheek, sliding down to press his thumb against his lips.

"Nick..." Warrick started, moaning when Nick pushed in over his tongue and back until Warrick swallowed around the thick digit. Moaning at the salty sweet taste, he shifted on the couch to accommodate his arousal.

Sliding his thumb out with a wet pop, Nick held his hand against Warrick's jaw. Sitting up and moving over, he placed his other hand on his hip.

"Were you gonna tease me to death?" Nick asked, a small smirk crooking the corner of his lips.

"Nick, I, didn't mean to. I just wasn't sure, and I didn't want to rush it," Warrick said, trying to breath evenly as Nick started to rub his thumb against his hipbone.

"Do I look like I'm a blushing virgin? I can handle going a little faster, Rick. Besides, you owe me for making work a very difficult place to concentrate."

Warrick stared up into his eyes and fondly shook his head, a hand coming up to pull down on his neck, joining their lips together. Soft exploration of the surface soon deepened as Nick sucked at his lower lip pulling until he opened up.

They kissed until Nick started to get light headed, and pulled up to stare down at Warrick.

"So. Did this great seduction have any action at the end?"

Warrick chuckled and couldn't help but grin. Nick in turn couldn't help but tongue at the resultant dimple. Moaning, Rick turned his head to capture his lips.

"Yeah. Come on."

Clothes came off and landed on the floor, as the two men stumbled onto the large bed. Shifting up, panting and groans filled the air as healthy, toned bodies strained against the other. The stockier, shorter figure rolled over the tall, lean form, thighs tense as they rocked back and forth.

Pushing at Nick's chest, Warrick reached over yanked the side table drawer open to grab the oil and condoms. Dropping them on the bed he pulled Nick back down and entwined their legs.

Nick thrust hard, months of celibacy driving him with need. He came out of the haze encompassing his vision when Warrick opened his hand and poured oil in it. Reaching down, he grasped them together in his large callused hand. Nick mouthed at Warrick's neck when he arched up with a groan, and got a firmer grip.

"Shit. Nick. Almost..." Holding Warrick's hair in one fist, his other tightened and twisted up, gliding quickly and smoothly with the warm, musky scented oil.

"Fuck me," Warrick moaned loudly as he jerked, his body straining as his cock jumped in Nick's hand spilling white fluid. The musky smell and the sight of Warrick groaning and coming against him, hit Nick in the gut. His stomach tensed, and his breath hitched as white heat flowed from him, spots dancing in front of his eyes as his body quaked with orgasm. Taking care not to collapse on top of Warrick, he shifted and melted back onto the damp sheets, panting to catch his breath.

"Damn."

"Yeah," Warrick agreed as his arms stretched over his head. Rolling over he threw an arm over Nick's muscled torso.

Nick grinned, and yawned as his body cooled off. Soon Rick got up and left the room, quickly returning with a moist towel to wipe them off. Throwing it on the floor, he returned to the bed and plopped down on his stomach.

"Was that an invitation, earlier? You really want me to fuck you?" Warrick's head turned on the pillow and beautiful sated green eyes stared into his. Neither of them spoke for a minute, and then Rick rolled onto his side, leg moving over his hips and an arm wrapping around his chest.

"Do you want to?"

"I'd like to, yeah, but you know, no pressure or anything," Nick said huskily, turning so that they fit together. He leaned forward to nuzzle Rick's neck, his hand sliding up his thigh to cup his ass. Rick shivered as his fingers lightly dipped in the crease and sighed happily against his lover.

"I'd like that, too. In fact, if you stay, we can have a morning play-off," Warrick said with a smirk, his eyes sliding shut, losing the battle of staying awake.

"Night, Rick," Nick whispered, and quickly followed his companion into unconsciousness.

*

Warrick woke up to wet heat surrounding his cock. He lifted up his head and saw Nick bobbing up and down, sucking hard. He gasped when Nick looked up, eyes twinkling as Warrick wrapped long legs around his head.

Pulling up with a soft pop, he pushed Rick's legs open and licked down to his sack, sucking it in to tongue for a brief moment. Kissing down, he nibbled down his cheeks and tongued into his hole without warning. When Warrick jumped with a shout, Nick grabbed his hips to keep him still and went to town.

Hoarse cries filled the room, migrating into moans and whimpers as Nick tongued him open, a thumb pressing firmly against the hot spot behind his sack.

"Condom," Nick rasped as he reached over to grab the oil. Warrick leaned over the side of the bed and grabbed the ones that fell from the night before.

Nick was busy finger-fucking him, fingers thrusting deep, curling up until Warrick yelled. As Nick stroked over the small nub, fingers twisting and pumping, he fisted Warrick's cock. Soaking in Warrick's cries and desperate humping, he pulled back to slip on a condom.

Warrick moaned softly when Nick spread him open, cock resting against his spasming hole. Pressing in slowly, he tweaked Rick's nipples, switching back and forth with one hand. With the other he rubbed a thumb over his seeping head, before closing his hand around the silky flesh.

He kept up the steady pressure and held Rick firmly in his hand, squeezing and jerking him off until he was all the way in. Holding still, he let them rest, and moaned as Rick began to clench around him. Rocking gently, he pulled back and pushed in slowly.

Soon Nick lifted his legs, hands holding them behind the knee, and with a nod from Rick he started a steady rhythm.

Rick twisted and gyrated his hips, milking his cock with his muscles. Nick groaned from the sweet pressure, and started to slam into him hard. Shifting, Nick thrust up and had to hold Rick down as he spasmed with each thrust into his prostate. Nick let him go and leaned over Rick's torso, sweat dripping down onto his chest as the slap of flesh meeting flesh intensified. Rick reached up and pulled Nick down for a kiss, tongues mating and lips clinging as heat engulfed their bodies and made them mindless to reach the pinnacle of pleasure.

Suddenly Rick gasped and convulsed around Nick, come spraying up to hit him in the chest with each pulse. Nick's hips continued to move raggedly, even as he came, a long moan drawn from his lips. Rick wrapped his arms around his neck and held on as his thrusts slowed and stilled. Nick sighed as he carefully pulled out of his lover, and threw the condom in a nearby trash bin. Grabbing the discarded towel from the night before, he wiped them down. Settling back into the bed, he rolled to his back and pulled Rick around with him, until he was resting against his chest.

Sliding a hand up and down Rick's spine, he bent his head down to kiss his forehead. Rick looked up and smiled, sated and boneless, he reached up and pulled Nick's head down again for a sweet kiss. Putting his head back down he got comfortable on his breathing pillow and began to doze off.

"So...I guess I can call you my boyfriend now, right, honeybun?"

Warrick's eyes opened as he snorted with laughter, a lazy hand slapping against Nick's chest. Eyes drifting back closed, a smile touched his lips.

"Sure thing...Sweetcheeks."

"Hey, Nick, man, what's with the grin? You win something?" Greg asked as Nick sauntered into the lab, little hiding his good mood.

"Yeah, Greg. I won *big-time.*"

Greg grinned, and lifted his eyebrows in a dance.

"Would that, by chance, have anything to do with Warrick walking funny?"
