A/N: Day 16 at last! Fluffy K rated Christmas fic to round out the holiday season.
"Not this again." Sherlock rolled his eyes.
Molly smacked him lightly on the shoulder. "Yes, this again'," she said. "Sherlock, you promised-!"
He sighed. Yes, he'd promised. "Fine," he grumbled, pulling out the box of Christmas things she'd had him lug up from the basement. "But I'm not wearing the antlers, and that's final!"
The Annual 221B Christmas Party, aka 'This Again'
"I don't know how you make him do it every year, Molly, but good on you," John said with a laugh.
"What, make him have the party or make him wear the -" Molly gestured toward Sherlock's head, currently graced with felt reindeer antlers.
Sherlock grimaced at them from behind Rosie's back. "I'm Sherlock Holmes, nobody makes me do anything," he said haughtily. Then Rosie laughed and clapped her hands and grabbed for the antlers, just as she had the last two years in a row - and Molly clicked a lovely photo on her mobile, just as she had the last two years in a row. "I do it for Rosie," he tried.
John shook his head. "Not fooling anyone, mate," he advised his best friend. "Rosie, who does Uncle Sherlock do things for, love? Hm? Who's his best girl?"
"Me!" Rosie squealed. Just as Sherlock gave John a triumphant smirk, the toddler pointed over his shoulder. "An' Auntie Molly! Unca Lock does ever'fing for Auntie Mollie 'cause he loves her!"
Molly grinned and ducked her head, a faint blush coloring her cheeks, and Sherlock, after kissing Rosie on the cheek and plunking the antlers atop her golden curls (just like the last two years), rose to his feet and pulled Molly into his arms for a warm kiss.
Just like the last two years.
