Summary: Wherein Greg wants to surprise Nick...

***

The keys felt heavy in his pocket; Greg still wasn't used to the idea of having keys to someone else's apartment -- and the fact that they were Nick's was even more alien to him. Nick had given him the spare set just two days ago and the newness of it all was still a little much. Of course, they had been seeing each other for months, but he hadn't really expected anything this permanent from Nick. He slid his hand into his pocket and wrapped his fingers around the smooth brass keys, just the feel of them sent a little rush of blood pounding through his veins; Greg grinned foolishly as he pulled open his car door.

Greg slid in behind the seat, his mind still on Nick and what had been developing between them. Nick had been adamant about the fact that no one could know about what had been going on with them. Greg wasn't entirely comfortable with the secrecy, but he could understand Nick's reasoning. As usual, it was, if nothing else, logical. Nick was ambitious where his career was concerned and Greg knew that if their relationship had become common knowledge around the lab both of their jobs could be jeopardized. For that reason, Greg was willing to continue the charade -- that they were just friends. Besides, if it kept him in Nick's bed, Nick's house, Nick's life, than he was willing to compromise a little when necessary.

Now, however, something was changing. Greg didn't want to put too much stock in the fact that he now had his own set of keys to Nick's apartment, but these were the thoughts that were tumbling around inside his head as he drove down the sun mottled streets towards Nick's building.

Greg knew that Nick wouldn't be home when he got there. The CSI had been stuck on a case that still needed to be wrapped up when the shift had ended. Greg was sure he would have at least an hour before Nick got home. He wanted to surprise him; Nick had no idea that Greg was planning anything that morning. As a matter of fact, Greg had bumped into him right before he left and had told him that he thought he was just going to go home to his own place to crash. Nick had seemed a little disappointed and the memory of his reaction made Greg smile as he drove past the garish casinos dotting the Las Vegas Strip. Nick's flicker of chagrin was short-lived; his pager had gone off and after he checked the message, he admitted that it was probably best if Greg went home. Particularly since Nick wasn't even sure how long he was going to be tied up ironing out the final details of his latest case.

Greg remembered the way Nick looked as he had walked away. The broad expanse of his shoulders stretching the thin cotton of his shirt taut across his back, his perfectly-shaped ass covered in worn denim, and his casual stride as he walked the length of the hall. Even though Greg had promised not to do anything that might raise anyone's suspicions, he couldn't stop himself from staring at Nick's back until he rounded the corner, disappearing from sight.

Caught up in the mental image, Greg didn't even notice that the light he was stopped at had turned green until the motorist behind him started honking his horn impatiently. He shook himself out of the daydream and proceeded through the intersection. Greg continued on, weaving through the early morning Vegas traffic. Finally he reached the turn leading to Nick's apartment building. He drove around to the back, parking in the designated visitors lot. Greg was positive that Nick wouldn't see his car since the numbered spot reserved for his apartment was right in front of the beige-stuccoed structure.

Eagerly, Greg bounded out of his car and engaged the lock. He couldn't wait to get upstairs and prepare for the surprise.

An Hour and a Half Later...

Nick pulled into the parking space in front of his building. He had been tempted to look around into the rear lot for Greg's car, but he stopped himself. He wished now that he had told Greg he was more than welcome to sleep at his place, but he hadn't. Instead, Nick had told Greg to go home and get some sleep -- it was too late to take that back now.

Nick got out of his vehicle and crossed to the opaque glass doors. He entered the small lobby and methodically checked his mailbox -- junk mail and a bill. Nick dropped the flyers and ad circulars in the trash can as he folded the bill envelope and stuffed it into his back pocket. He would look at it later; right now all he wanted to do was get into his bed and sleep for a few hours. Maybe, he thought to himself as he climbed the stairs, it had been best that he hadn't invited Greg over.

Wearily, he stepped onto the landing in front of his door. He slid the key into the lock and entered his apartment. Nick flipped on the light switch and immediately noticed that a few things seemed to be out of place. The realization smothered the tiredness as a rush of adrenaline coursed through him. Nick surveyed the living room and kitchen, there was a cup sitting on the counter and the LED lights on his stereo were glowing -- Nick was sure that he hadn't left any dishes out and that he had turned the stereo off. The hairs on the back of his neck prickled and a chill shuddered up his spine as he pulled his gun from its holster. Someone had been, or still was, in his apartment.

Ever since that incident with the stalker, Nick had been keenly aware of his personal surroundings. Holding the gun at the ready, he quietly moved down the hallway. Nick ducked his head around the door frame of the bathroom -- nothing. Slowly, he crept further down the hall towards the closed door to his bedroom. He pressed his ear up against the flimsy wood door, listening for any sound that was out of the ordinary. Nick could hear some muffled noises but he couldn't make out what it was. Gingerly, he twisted the brass doorknob, the metal cold against his palm, and he felt his body tense as he threw the door open.

Nick stepped over the threshold, his gun held out in front of him. The door banged loudly against the wall as he scanned the room quickly. A startled yelp came from the direction of his bed and Nick jerked his head at the sound.

The noise of the banging door woke Greg and he sat bolt upright, a strangled cry escaping his lips. His eyes widened as he saw a flash of sunlight reflect off the steel of the gun barrel. Slowly, his sleep-crusted eyes focused on the man holding the weapon.

"Nick," he called, wanting to be sure Nick realized it was him before he did something he would regret.

"Goddammit, Greg," Nick barked, lowering the gun. "You're lucky I didn't shoot you."

"I'm sorry," Greg offered, feeling a little silly as he sat there in Nick's bed, naked, minutes after a gun had been pointed in his direction. "Really Nick, I'm sorry. I just
wanted to surprise you," he added sheepishly, self-consciously pulling the sheet across himself.

"Shit," Nick tried not to smile. He set his weapon atop the scarred dresser and crossed over to the bed. "You're crazy," he commented, perching on the edge of the mattress.

"You're just now noticing that?" Greg asked, teasingly.

"I guess so," Nick grinned that perfect smile. The smile that made Greg's heart flutter and his crotch tighten.

"Damn, Nick...I didn't mean too...it was just supposed to be...surprise," Greg replied, fumbling over the words.

"I'll get over it," Nick joked. "And, although I'm glad you're here. Don't. Do. That. Again," he added, joking aside as a serious expression masked his face.

Cautiously, Greg lifted his arms and began to soothingly massage away the tenseness that had settled in Nick's shoulders. "I promise," he swore, his fingers tracing an ‘X' across his chest.

Nick smiled, he couldn't help it. Greg was just too...too...Greg, and that was just one of the things that attracted him. He leaned back slightly, twisting his head to the side as he dropped a gentle kiss across Greg's full lips. Unhurried, he sat back up, savoring the feel of skilled fingers pressing into his muscles. Nick felt the bed shift beneath him as the other man moved behind him. Greg's teeth nipped at the tender skin below his ear, warm breath grazing his cheek.

"Nick," Greg whispered, the word hissing past his ear. "The gun was a little much, but I'd love to see your handcuffs..."

Nick could feel the blood rush to his face, a crimson stain flushing his cheeks as he turned to look at Greg. "Wha..." the question stuttering from his mouth.

"Handcuffs," Greg repeated, the word muffled as he traced the edge of Nick's ear with his tongue.

"I don't have any," Nick mumbled.

"You're not fooling me," Greg coaxed, continuing to blaze a wet trail down the side of his neck. "I've seen them," he admitted, nibbling at the smooth skin hidden just below Nick's collar.

Incredibly, Nick blushed even hotter; he lifted Greg's chin with his fingers so that they were now looking directly at one another. "You're unbelievable, you know that?" Nick muttered, unable to keep himself from pulling Greg closer.

Nick bent forward, crushing their mouths together as they tumbled backwards onto the bed. He didn't break contact with Greg's mouth as he straddled his slim, naked hips. Nick moaned, the sound low in his throat, as he felt Greg arch beneath him, a hard cock brushing against his thigh.

Nick bore down a little harder and their kiss intensified. The sensation of tongues sliding against one another, slippery and wet, as they writhed together atop the rumpled bedding.

Greg's hands scoured Nick's body, eagerly mapping out each muscle in his back. Finally, he slid his hands beneath the waistband of his jeans. Reluctantly, he pulled his mouth away from Nick's; Greg needed to feel Nick's skin against him and the only way to accomplish that was to get the man out of his clothes.

"Too many clothes," Greg panted. "Too many," he repeated, tugging impatiently at the hem of Nick's shirt.

Obligingly, Nick began to strip. He knelt over Greg as he pulled his shirt off while the other man worked on the buttons of his jeans. Nick playfully slapped Greg's hands away and stood up. Wriggling, he slid the pants down over his hips, letting them puddle at his feet. "Stay right there," Nick ordered him before Greg had a chance to move. He kicked off his shoes and bent over to pick up his clothes. Nick crossed over to the closet and disappeared inside.

Greg was holding his breath; he could hear rustling in the closet and wondered if Nick was really going to take his suggestion seriously. He closed his eyes, hoping he wasn't going to have to wait too long before he found out.

"Is this what you were talking about?" Nick asked, standing at the foot of the bed.

Greg opened his eyes, his breath expelled in a rush as he saw the chrome handcuffs dangling off of Nick's fingers. He couldn't believe this was happening; he had never mentioned this particular fantasy before and now it was being played out before his eyes. "Uh huh," Greg answered, unable to form anything resembling a coherent sentence. He couldn't move, he was afraid if he did anything he'd wake up from a dream.

But this wasn't a dream. Nick was crawling back onto the bed, pinning Greg's arms above his head as he locked the cuffs onto his wrists. He dug his feet into the mattress and scooted further up onto the bed; Greg wrapped his hands around the slats of the headboard, waiting to see what Nick was going to do. His mind was still struggling to grasp the idea that Nick was actually doing this, that he was willing to set aside some of his own inhibitions...for him.

Nick watched with rapt attention as Greg situated himself on the bed. He had never done anything like this before and he wondered why he was doing it now. But, Nick already knew the answer to that question. Greg. It amazed him, the things he was willing to try with Greg. And that was yet another reason he was so attracted to him. Nick knew that Greg wouldn't have laughed at him if he had been too embarrassed, and that knowledge was what gave him the boldness to do this now.

Nick smiled; a naked Greg, sprawled wantonly across his bed, trusting him with his body was a sight to behold. He sucked in a breath, inhaling deeply. His body reacting to the sight, erection throbbing as he lowered himself over Greg, covering him completely.

The heat between them as their skin touched was like fiery combustion. Nick dipped his head, engulfing Greg's mouth with his own. The kiss was all-encompassing -- warmth and wetness mingling with undeniable hunger.

Greg mewled, the sound almost swallowed in the kiss. Unwillingly, Nick pulled away and began to shower his already sweat-slicked skin with his tongue; he could taste the mixture of salt and that thing was the essence of Greg as his mouth sought out every inch of exposed flesh.

Greg moaned, eyes closing, as Nick's lips fluttered along the length of his cock. "Oh, Jesus," he sighed.

Nick's tongue slipped out, skimming the tip and lapping savagely at the sticky pre-cum that dripped from the slit. Opening his eyes, Greg watched as Nick wrapped his lips around him, carefully sliding his mouth down the entire length. Just the sight of Nick as he began to move his head up and down was almost enough to push him over the edge. Greg gripped the slatted headboard behind him, his knuckles ghostly white with the effort, as Nick's teeth barely grazed the sensitive flesh.

"Fuck," Greg panted. He began to move his hips, thrusting into Nick's willing mouth as the wet strokes sped up. Suddenly, his whole body tensed as his climax swept over him. Bright points of light exploding behind his eyelids as he felt Nick swallow the last drops of his orgasm.

Greg thought he was going to hyperventilate as Nick pulled away, the movement agonizingly slow. His breath came in heaving gasps and his head felt as if it were floating in an ocean of hazy mist. Greg sensed Nick's hands on his chest, his touch calming the overheated skin.

"Breathe...slowly," Nick instructed soothingly.

Gradually, Greg's shallow breaths evened out and he opened his eyes. His throat felt ragged as he tried to speak, "That was..." His voice failed him and, instead, he leaned forward slightly capturing Nick's mouth in a kiss. A kiss that conveyed everything he was feeling -- all of the passion, the desire, the love -- in that one simple gesture. Greg was sure that Nick felt it; he was sure because he felt the same things in the way Nick was kissing him in return.

The kiss seemed to last forever before they finally separated, their breathing labored. Nick's fingers gently traced the curve of Greg's jaw.

"Let me take these off," he said, indicating the handcuffs that still bound Greg's wrists.

He reached behind him, fumbling for the key he had left on the bedside table. With practiced dexterity, Nick slid the key into the lock, freeing Greg's arms. Tenderly, he massaged the bruised skin where the steel cuffs had bit into Greg's flesh.

"Shit," Nick muttered. "I hurt you," he added, frowning as he looked into the sated eyes of the other man.

"It was worth it," Greg answered, voice thick with the memory of what had just transpired between them. "Besides, it's just a little red," he said, examining the chafed skin. "It'll give me something to remember this by."

"Are you serious?" Nick asked, his voice uncertain. "I hur..."

Greg cut him off, placing a finger against his lips before he could repeat those words. Affectionately, he caressed Nick's stubbled cheek. "Nick, you would never hurt me, of that I'm sure," he quieted him. "What you did was perfect, everything I'd imagined..." his words barely above a whisper. Greg watched as Nick's expression shifted, the anxious frown slowly melting into a smile. "Besides," Greg began, a teasing lilt to his voice. "Maybe next time we can discover on of your fantasies..."

Nick blushed. Greg laughed gently, leaning in for another kiss.
