A/N: This story doesn't take place during or in between any of the episodes. This is a few years after Sherlock comes back with established Johnlock. Reviews are nice, unexpected kisses!
John sat in his usual chair in the living room of 221b Baker Street. It was cold outside and it was going to snow, so John planned to spend his day indoors, in his favorite chair, with a hot cup of tea and a good book. His new husband, Sherlock, was out using the bad weather to his advantage in some experiment. Something to do with the freezing rates of multiple liquids in different containers. They had recently gotten a case from DI Lestrade about a missing woman. When the police came to her flat two days ago, as per request from her worried co-worker, they found it to be ransacked. A ransom note was left on the table. Sherlock had been called in almost immediately to investigate, and as soon as they got home Sherlock had gathered his materials and gone outside to start his experiment. John didn't complain about this; after all, this one was outside and didn't involve any dead carcasses that John was aware of. It was a welcome change. The only thing John had asked of Sherlock was that he wore his coat outside. You would think that a grown man would not need reminding about something as simple as wearing a coat when it's cold outside, but then again you don't know Sherlock Holmes. John looked up as he heard the slamming of the door and Sherlock's heavy footsteps on the stairs. The tall man walked through the door and John smiled at him.
"How did your experiment go?" He asked chuckling to himself as Sherlock shook his head to dislodge the snow that had made its home in his hair.
"The blood froze at the exact time I thought it would! This just proves my theory!" Sherlock didn't bother to explain what his theory is, and John didn't ask as Sherlock had pulled out his phone and was texting Lestrade. Sherlock smiled in satisfaction as his phone sent the message. John smiled in response but then frowned in confusion.
"Sherlock, where are your gloves? And your coat for the matter?" Sherlock shrugged in answer.
"I didn't think it was necessary for me to have it." John blinked and Sherlock walked briskly into the kitchen to check some of his refrigerator experiments.
"Didn't think you needed – Sherlock! It's barely 0° out!" Sherlock grunted, his head in the fridge and his attention elsewhere. "Sherlock you must be freezing. Do you want me to make you some tea?" John tried hard to focus on keeping Sherlock from getting hypothermia instead of on his growing annoyance at Sherlock's surprising idiocy. Sherlock waved his hand and said: "Don't bother."
John sighed and put the kettle on to boil anyway. Sherlock shook his head but smiled. When the water was boiled John pulled out two mugs and the tea and poured them both some of the steaming liquid. Sherlock took the mug from John and drank from it, heading towards the living room to check his website for new cases. He set the mug down on the oak table and opened the laptop. John followed Sherlock quietly into the room and as Sherlock sat in his chair he stood behind him.
"Hey, Sherlock?" Sherlock kept his eyes on his computer screen, but turned his head towards John.
"Hmm…?" John leaned in quickly and placed a chaste kiss on his husband's lips. Sherlock looked at him curiously.
"I was warming you up." John explained smiling. Sherlock nodded in understanding, and then bit his lip in thought.
"I'm still kind of cold." Sherlock complained, looking expectantly at his husband. John rolled his eyes and just barely held back a smile.
"You are so needy." John said, before leaning in to kiss Sherlock once more.
