Greg's face lit up as Nick centred the tree in the stand. It hadn't taken much convincing for Nick to agree to get a real tree. Nick often caved when it came to Greg, especially when Greg flashed his childish grin. In fact, it was moments like those when Nick realized just how much he loved Greg. He watched as Greg poured some water in the stand and added sugar, swirling it around with his finger.

"It's a good tree," Greg commented, sliding back a few feet and sitting cross-legged on the floor. "Big, but not too big. Full, too." He admired the tree. "How did you ever live with that fake thing you called a 'tree'?" Greg asked. "I mean, really. It's a crime against nature."

Nick had to admit that Greg was right. He hadn't had a real tree since he was about seven and his family learnt that one of his sisters was allergic to the pine; having a real tree brought back memories. "Okay, I get it G. You were right. It's perfect." He sat down behind Greg and extended his legs on either side of the other man. "So do you want to decorate it now or what?" he whispered in Greg's ear, and Greg shivered at the sensation. He leaned back against Nick's chest and ran his fingers up Nick's thigh.

"We could," he murmured, pressing himself closer to Nick. "Or… we could wait a bit. I mean, the tree isn't going anywhere…" he trailed off as Nick's tongue slowly began tracing his ear. Greg groaned and rolled his head to the side, exposing his neck to Nick. The other man sucked at the skin there, leaving behind a red blotch that Greg wasn't sure he could cover with anything less than a turtleneck. And he didn't even own a turtleneck. But thoughts of his wardrobe were pushed to the back of his mind as he felt Nick move to lie back on the floor. Greg twisted around and stretched to cover Nick's body with his own so they were face-to-face.

Greg leaned downwards - or maybe Nick leaned upwards; he really wasn't sure. But he felt Greg's lips pressed against his and he didn't really care which of them started the kiss as long as it was happening. Greg parted his lips slightly, allowing for Nick's tongue to push its way into his mouth and lightly rub against his. Greg moaned softly at the sensation, grinding his hips up against Nick's body. His hand slid down Nick's torso and tugged the bottom of his shirt out of his pants. Sliding his hand underneath, he ran it up Nick's smooth skin and gently pinched his nipple.

Nick pulled away from Greg for a split second to rid himself of his shirt and then, clasping his hand around the back of Greg's neck, he drew Greg back down. He claimed his lips in a searing kiss, more desperate and needy than the previous. Greg's hands roamed Nick's chest, mapping the hard muscles underneath Nick's surprisingly soft skin. His had slid along the waist of Nick's pants as he trailed his lips down Nick's throat. Working the button open and the zipper down, he slid his hand down Nick's boxers to stroke his half-erect cock. Nick lifted his hips, grinding against Greg's hand as Greg sucked lightly at his collarbone.

Nick glanced quickly at the window to make sure the blinds were drawn before he reached down to push his open pants and boxers own over his hips and kick them down around his ankles. He gently pushed Greg's hand away from his erection and flipped them over so Greg was trapped underneath him. He sat up to pull his pants off from around his angles and then reached to slowly undo the buttons on Greg's loud shirt.

"I thought you got rid of all these shirts," he murmured, lips pressed against the skin he was exposing along Greg's chest.

Greg laughed softly. "Kept a few as sentimental pieces." He groaned as Nick bit lightly down on his nipple, his hips instinctively thrusting up against Nick's body. Nick snickered against Greg's skin at the other man's not-so-subtle hint and reached between them to undo Greg's pants. He trailed soft kisses down Greg's stomach, stopping just to slide Greg's pants over his arched hips, and he wasn't really surprised to see Greg not wearing any underwear. Greg thrashed his legs wildly in an attempt to kick off his pants, but stopped when Nick's mouth closed on the head of his penis. Greg moaned loudly and writhed as Nick held his hips down, his tongue swirling slowly - almost tortuously - around Greg's erection.

"Nick…" Greg ran his hand through Nick's hair, his fingers threading through the dark strands. He tugged lightly at his lover's head, watching as Nick looked up at him. "Nick… please. Now." Greg couldn't seem to remember how to string a simple sentence together at the time and that was another thing that Nick loved about him. There was no doubt in his mind that if anyone could literally talk someone's ear off, it would be Greg. Where some people would use four words, Greg would use at least ten. He loved the sounds of his own voice, and Nick had to admit that he loved Greg's voice as well. Moments like this, though, Nick loved even more. When Greg was too excited and aroused to even form a sentence - now that was a special moment, a special state that only Nick got to witness. It was his to hold onto and know that he knew the only real way to shut Greg Sanders up.

Nick leaned in and placed a quick kiss on the head of Greg's penis before getting up for a quick search for lube. When he reappeared, Greg had managed to get his pants and shirt off and was lazily stroking himself. Nick took a moment to watch Greg's hand caressing his own cock, mesmerized by the motion.

"Are you going to come back over here or am I on my own for this?"

Nick smiled to himself and kneeled between Greg's spread legs, his eyes still fixed on Greg's moving hand.

Greg brought his knees up close to his chest and Nick drizzled some lube on his fingers. He pressed a finger to Greg's entrance, and then another.

"Fuck… don't tease," Greg muttered. Nick laughed out loud and prepared Greg as quickly as possible before easing his swollen cock into Greg. He paused when he was fully inside, allowing Greg to adjust to his presence. When the other man started moving beneath him, Nick pulled out and thrust again, over and over with Greg moving his hips with every thrust. Nick's hand slid between their bodies to grasp Greg's cock and stroke it roughly. Greg gasped and ached into Nick's grip. He was close - closer than he should be - and it only took a few seconds for him to come, coating his stomach and Nick's hand. Greg was panting as Nick stopped moving, watching the relaxed smile spread across his lover's face. He felt Greg shifting under him, urging him to start moving again; he didn't need to be asked twice. Nick groaned and started thrusting into Greg, quick and hard and focused. A few hard thrusts later, Nick started to feel the heat building up in the pit of his stomach and it was a few moments later when he found himself coming hard into Greg. He collapsed on top of Greg, breathing heavily. He stayed there for a few seconds, lips pressed against the crook of Greg's neck, tasting the sweat-salty skin.

Greg wrapped his arms around Nick, pulling him so close that Nick was sure every inch of their skin was touching. He darted his tongue out to gently lick at Greg's skin.

"Do you have any tinsel?" Greg asked suddenly, his voice sleepy but seemingly unfazed by Nick's tongue.

"What?" Nick asked, slightly confused.

"Tinsel. Stringy stuff, generally put on a tree? Supposed to look like snow?"

Nick looked up at Greg. "No, man. That stuff's tacky."

Greg's eyes widen in mock horror. Or maybe it was real horror, Nick wasn't entirely sure. "Tacky? No way. This coming from the guy with the fake tree?"

Nick groaned and rolled off of Greg and turned onto his side to face him. "At least the tree sorta looks real. That stuff just looks like cheap silver plastic, not snow."

Greg scoffed. "Well technically it is cheap silver plastic, but it does look like snow. If it's put on right, of course."

"It doesn't even snow in Vegas, G. It wouldn't even be realistic if it looked real."

Greg turned his head to look at Nick and pouted. "Why does everything have to be realistic?"

Nick tried but couldn't hold back his laugh. "And this is coming from the guy who insisted on a real tree."

"Totally different," Greg argued. "See, a real tree isn't about the tree itself. It's about the smell of the tree and the pile of needles on the floor and all that sentimental stuff. A fake tree is about posing. It's a tree wannabe. Can't hack it as a real tree so they dress up like a tree but everyone knows it's not real."

"And how is this different from tinsel pretending to be snow?" Nick asked, trying to humour Greg.

"Well tinsel is also a poser, I won't deny that. But you can't bring real snow inside and stick it on a tree. So the tinsel makes up for what cannot actually be there. So really, it's doing the real snow a favour by saving its life." Greg flashed Nick his you-can't-resist-me grin. "It's a hero in its own right."

Nick rolled his eyes. "Fine, fine. You win. We'll go and shower and run out to get you some tacky silver tinsel to throw all over the tree and make a big mess. And you're going to be the one to clean up the pile of pine needles and tinsel, by the way."

Greg's grin widened, and Nick knew that he'd probably be the one to clean up the tree's mess but when the other man looked at him that way, he didn't much care. He leaned forward and pressed his lips to Greg's.

"Mmm… did you say 'shower'?" Greg mumbled against Nick's mouth. Nick chuckled and pulled Greg up off the floor and towards the bathroom.

"Whatever you want, Greggo."
