A/N: For today's prompt: Opening presents on Christmas Eve.
"But we've always opened presents on Christmas morning, aside from when we're busy catching bad guys," Deeks protested mildly as Kensi dragged him into the living room. "It's our tradition."
"All I'm asking you to do is open one present," Kensi replied, ignoring his complaints as she directed him to sit down in front of the Christmas tree. They'd already had dinner-their best attempt at roast chicken with mashed potatoes-and usually they'd be genially bickering over what movie to watch.
Apparently Kensi had other plans as she flicked off the main lights, leaving the room bathed in the dim, twinkling glow of Christmas tree lights. She was practically vibrating with anticipation.
"I'll be right back," she told him and then disappeared upstairs. She reappeared a couple minutes later with a small, thin box cradled between her palms. It was perfectly wrapped in silver paper with a shiny red bow and tiny ribbons dangling over the sides. He'd never known Kensi to wrap anything so carefully; he was definitely curious.
Kneeling down in front of him, Kensi laid the gift on his knee. Her expression was filled with a mixture of anticipation and nervousness.
"What's in here, the keys to a fancy schmancy new car like on all the TV ads?" he guessed, turning the box from side to side. "Oh, I know one-way tickets to a nude beach resort." Kensi snorted at that and couldn't seem to resist leaning forward to kiss him.
"You are so ridiculous. Open it," she instructed him. He slid a finger under one seam, pulling the tape loose with one swift movement.
"Vouchers for rock climbing. My own ski jet." He continued listing off items of varying ridiculousness while he removed the wrapping paper. Underneath there was a plain white box and he lifted the lid off with the tips of his finger, watching for Kensi's reaction. She leaned forward on her knees slightly.
"If this isn't a-" he started to say, looking into the box. There was a small, oblong object nestled in red tissue paper. He lifted it out slowly, glancing back up at Kensi, his mouth open slightly in surprise, and found her with her hands pressed over her mouth. "Is this a-?"
"Mm-hm," Kensi answered.
"Oh my god, you're pregnant!" he shouted, reaching for Kensi. She crashed into his arms, grasping the back of his neck as she kissed him desperately. He felt moisture on his cheeks and pulled back enough to look at Kensi.
"Why are you crying?" he asked, breathless with happiness. Swiping at her cheeks, Kensi laughed, the sound shaky.
"Ugh…because I've been dying to tell you for five days," she answered.
"We're pregnant," he repeated, almost unable to believe it.
"I'm sorry it wasn't the keys to a new car," Kensi said playfully and he crushed her back against his chest.
"Are you kidding me, this is the best present ever." He was still holding the pregnancy test and he held it up, tilting his head. "Admittedly a little gross since you peed on it, but still the best present."
"Idiot," she said fondly, leaning in to kiss him again. Deeks tossed the pregnancy test back in the box, dragging her down to the floor with him. As Kensi settled on top of him, haloed in twinkling lights, he couldn't imagine being happier.
"Merry Christmas, baby," he whispered.
"Merry Christmas."
