A/N: Happy first day of December and Densi-mber!

This story takes place in the last couple years. For Densimber Day 1 prompt: Densi buying a Christmas tree.

"How about this one?" Deeks asked, reaching in between the fragrant branches of a large spruce tree and grasping the trunk.

"I liked the last one better," Kensi commented, craning her neck to see the very top of Deeks' pick.

"But the top branch was crooked."

"I know. I like things with imperfections." Kensi slanted a mischievous glance his way and turned to look at another tree that was less massive and almost perfectly straight.

"You should get the big tree," a soft voice said from behind them. Kensi glanced around until she saw a little boy with dark brown skin peering at them from between two trees.

"You think so?" Deeks asked, turning to face him. The little boy nodded, eyes wide.

"It's the best one here," he said, lowering his voice as though someone else might hear and decide to snatch the tree up. Deeks grinned and sank into a crouch.

"I agree, but my wife likes Charlie Brown trees." He bobbed his head to the side in Kensi's direction.

"Hey, I saw that movie!" The boy said excitedly, squeezing between the trees. "Do you know Rudolph the Red Nose Reindeer?"

"I do." Deeks stood again with a groan, brushing off his knees as the little boy came to stand between them. "My name's Marty, by the way," he added. "This is Kensi."

"Hi! My name is Bobby. I'm five years old." He proudly showed them five fingers.

"It's nice to meet you." Deeks offered him his hand to shake, which seemed to delight Bobby even more. His hand looked ridiculously small engulfed in Deeks'.

He turned to Kensi, his chin tucked down by his chest, and shook her hand without looking at her.

"You're really pretty," he said shyly. Kensi grinned, completely charmed.

"Thank you," she said and he ducked his head again.

"But not as pretty as my mom. She's the prettiest."

"Did your mom come with you?" Deeks asked, managing to make the question sound casual. "You look pretty strong, but I'm not sure you can carry this tree without a little help."

"You're silly. I came with my mom," he said with another giggle. Kensi noticed that one of his bottom teeth was missing.

"Do you know where she is?" Kensi asked, crouching a little and Bobby nodded.

"Uh-huh. She's over there, looking at the little trees. I wanted to get a big tree, but she said they're too espensive." He pointed to a section of trees that were decidedly less impressive.

Kensi felt her heart clench as his smile faded a little bit.

"Hey, you can still put presents under a small tree," Deeks pointed out and Bobby's grinned returned in full force.

"Santa's gonna bring me a Spider-Man bike this year!" he exclaimed excitedly. "I guess if it's too big to go under the tree, he can put it next to the tree."

"That sounds amazing and I'm super jealous." Kensi rolled her eyes as they started debating who the best Avenger was.

"We should probably go find your mom before she starts to worry," Kensi interrupted after a couple minutes.

"I guess..." Bobby sounded a little disappointed, but didn't resist when Deeks put a guiding hand on his shoulder. They started to walk towards the spot Bobby had indicated.

"Ooh, I think I dropped my phone somewhere," Deeks said suddenly, patting down his pockets. "I'll be right back." Kensi eyed him suspiciously as he turned around and went in the completely opposite direction.

"C'mon, Bobby. I'm sure De-Marty will be back in a minute."

They found his mother, a woman who looked maybe in her late 20's, looking a little harried and worried as she craned her head around two medium sized trees. She caught sight of them and ran over, her expression turning to one of relief mixed with exasperation.

"Bobby, I told you to stay close by," she said, grabbing his shoulders and giving him a quick once over.

"Mommy, this is Kensi! She's married to a guy with hair like the guy who sings about country roads. And he likes big trees too!" Bobby told her excitedly before Kensi could explain the situation.

"He was just giving me and my husband some of his expert Christmas tree advice," Kensi clarified.

"Well, thank you for bringing him back." She hugged Bobby against her side, bending to press a kiss to his head. "What would I do without you? I hope he wasn't any trouble."

"Oh no, he was perfectly charming." Kensi smiled at Bobby, who was fiddling with his mom's jacket now.

"He's definitely that," she agreed with a slightly exasperated smile.

"Ma'am, we have your tree ready," one of the farm employees interrupted, directing his statement to Bobby's mother. He pointed several feet away where another employee was carrying a mesh wrapped tree.

"Hey, I think that's my tree, mommy!" Bobby shouted excitedly.

"No, Bobby, it's not ours," she said, resting a restraining hand on his shoulder. She turned to the employee "I think you made a mistake. I didn't buy a tree yet."

"No, someone else bought it for you."

"Who?"

"They want to remain anonymous, but said they saw you checking out that tree and figured it was in the spirit of things to make someone's Christmas brighter." He shrugged. Bobby grew steadily more excited and in a few minutes managed to convince his mother than the tree was indeed theirs.

Glancing around, Kensi saw Deeks emerge from the store at the center of the tree farm, two foam cups balanced in one hand as he slipped his wallet back into his pocket. Kensi narrowed her eyes, walking over to him with her arms crossed.

He grinned and offered her a cup.

"Hot chocolate?" She took it, but didn't take a sip.

"That was a pretty slick move, Mr. Deeks," she commented. Deeks took a healthy gulp and scrunched his nose.

"I have absolutely no idea what you're talking about," he said lightly, looking over at Bobby. He was practically jumping up and down in excitement while two men helped strap the tree to his mom's car.

"You made that little boy's day. Possibly his entire Christmas." Deeks sighed, seeming oddly embarrassed.

"It wasn't much," he said with a shrug. "I've been that kid, you know? I hated the way it made me feel when we couldn't afford something. And I know it killed my mom. Now Bobby's mom doesn't have to choose between making her son happy and paying the bills. And Santa has somewhere to put that Spiderman bike."

Kensi wrapped her arms around him, careful not to spill hot chocolate down his back, and leaned up to kiss his lips. Not caring that there were dozens of people surrounding them, she gently cupped his cheek.

"You are such a good man, Marty Deeks," she told him, overwhelmed with love and affection. He bobbed his head.

"Sometimes."

"Always." She shifted back and looped her arm through his. "Now let's go find you the second biggest tree this place has."
