"Sherlock!" John shouted as he moved up the stairs towards 221B Baker Street. He side kicked the door open, still flicking through the envelopes that had arrived for the pair. Sherlock was perched on his usual chair, staring intently at a-
"Is that a severed head?" John exclaimed.
"Why are you so shocked you were with me when I got it." Sherlock said blankly.
"I've been out all morning." John said flatly.
"Oh. Well you were awfully quiet."
"No you were just playing the violin awfully loud." John said, chucking Sherlock's envelopes at said mans curly head.
"Not interested." Sherlock said, brushing them into the floor. John sighed and shook his head. He headed over to the kitchen and flicked the switch on the kettle.
"Tea?" He asked, turning back to Sherlock only to find that his friend was right behind him.
"Jesus! Don't do that!" John yelped, watching Sherlock carefully as the taller man stepped closer, now invading John's personal space.
"Uh- Sherlock?" John trailed off as Sherlock stepped closer again and reached to tilt Johns head up.
"Interesting." All of a sudden Sherlock was gone, sweeping his way back to his chair. John stood for a second and gaped at him before coughing and turning back to making the tea.

The incident in the kitchen was mostly forgotten in the next few hours as Greg Lestrade (or Graham as Sherlock said) came to them with a new case, leading to Sherlock and John going halfway across London as they tracked down the thief of some precious jewels from the National History Museum. As always, John was fascinated with the way Sherlock picked clues out of seemingly nothing and put them together to solve the case. However, when the pair stopped off at a small restaurant to get some dinner before heading home, Johns mind wandered back to the kitchen and the way Sherlock stood nearly pressed against him.
"Interesting?" John said, looking at Sherlock who was half eating, half drifting in his mind palace.
"Hmm?" Came the non-committal reply.
"Earlier. In the kitchen you said interesting. What's interesting?" John asked.
"Just a small experiment I am doing." Sherlock said, putting a chip in his mouth and once again drifting as he chewed. John rolled his eyes.

The nature of Sherlock's experiment was only revealed several days later, by which time, John had almost grown used to Sherlock invading his space. Almost. He didn't quite click on to what Sherlock was doing until he was in the kitchen (trying to put together some semblance of a normal dinner) and Sherlock pressed right behind him, his tall body completely touching John's shorter one.
"Uh. Sherlo-?" John was cut off as Sherlock very deliberately leant forward and pressed his lips to Johns neck.
"Sherlo-oh." He once again trailed off into a kind of happy him as Sherlock kissed further up his neck before turning his head gently and pressing their lips together. After a few moments John pulled away.
"Is this what your experiment was about?" He asked, trying to smother the wide grin that was starting to spread across his face.
"Yes." Sherlock said softly, smiling shyly. John shook his head slightly and smiled sweetly.
"For someone so clever you really can be stupid. Next time just lead with the kissing." John stated and leaned up to kiss Sherlock once again.
