As she stood in front of the tree, red tinsel held firmly in her hand, the consulting detective stormed into the apartment. Huffing and puffing after what she could only guess as another "boring" case.
"You're home early." She said, with her back turned to him as she wrapped the tinsel around the middle of the tree, making sure it was sitting right before returning to the box of decorations that she had placed on the table.
"How was the case?" She pulled out a long train of silver tinsel and began to continue her decorating while Sherlock ranted about how tedious his recent case was.
"..It was obvious the daughter had done it, no one noticed the pack of cards." He stated, collapsing onto his chair once he removed his scarf and jacket, hanging them in their usual place behind the door.
"Only you would notice something like that, Sherlock." She mumbled, tucking an end of tinsel onto a branch and making sure that it wouldn't fall off.
"Where is John?" She asked, finally turning around to face the detective.
His hands were clasped in front of his face in their usually praying style, his eyes blankly staring at the empty chair opposite him.
"Oh he went to bed, complaining that he was tired."
"Seems a little early doesn't it?"
She closed over her almost empty box of decorations that she used for the tree. All she had to do was finish hanging some colourful lights on the mantelpiece and some tinsel around the mirror.
"It's half past eleven, I wouldn't say it was that early would you?"
It's half past eleven? She hadn't been decorating the apartment for that long had she? She had completely and utterly lost track of time she had been so busy.
She had been out for the entire day, gathering the presents, assisting Mrs Hudson in baking some cakes and retrieving the decorations from the loft.
"Oh my god." She muttered, pinching the bridge of her nose.
Now that the hour of the evening had hit her so did the lack of energy she had left.
"How long have you been decorating for?" Sherlock removed his eyes from the chair and stared at the exhausted woman before him.
"Not long," She sighed. "But I've been on my feet all day and I hadn't bothered to check the time."
It was now Sherlock's turn to sigh and he soon pushed himself off of his chair. He walked over to the cardboard box, removing the lights from them.
She watched him with curious eyes with a mix of fascination. She placed her hands on her hips.
"What are you doing?" She asked, watching him as he began to pin the lights along mantelpiece.
He hummed, finished the second pin before turning his head to face her.
"Helping you finish decorating so you can go to bed. In my defence, you look exhausted." He stated, returning to the task at hand.
She gratefully sighed and made her way to pins, carrying them to Sherlock. She patiently stood next to him, handing him a pin whenever he needed one.
Once the lights were finished he began to stick the tinsel around the mirror - since he was clearly taller than her and would require a chair or a stepladder to reach it. All she could do was watch him, her eyes trailing over every little detail.
From each curl atop his head to the way his eyes narrowed in concentration.
She would never confess to him, but she already had a crush on the consulting detective. Sure, he was arrogant and a little mean from time to time but that didn't stop her feelings from growing.
He finished the tinsel and sighed contently before returning to the box. He pulled out the one piece of ornamentation that she had never used for Christmas in her life but it was clear Mrs Hudson had kept it at the bottom of the box for a while.
He held it above his head and smiled curiously at it. And she couldn't control the blush that was slowly creeping onto her cheeks.
"What are you doing?" She asked, nervously.
"Nothing." He smirked charismatically.
"S-Sherlock," She stuttered as he held the small plant above their heads, twirling it around between his fingers. "Whoever stands underneath the mistletoe has to kiss the other-"
She didn't have a chance to finish her statement before a set of lips were carefully placed onto hers. She was in a state of shock but soon, she relaxed and eased into it, wrapping her arms around his neck and tip toed ever so slightly.
He lowered his hand and placed both of them on his hips, sharing sweet and anxiously placed kisses as the heat increased rapidly.
As quickly as the kiss began it slowly came to an end. Sherlock gingerly pulled away, gazing into her (e/c) eyes as she watching his.
"Merry Christmas, Miss (F/N) (L/N)." He whispered, pecking her lips one last time.
