A/N: Okay guys. I really hope this isn't too OOC; to me this is just another way Sherlock is curious and experimental, he wants to try and understand. Plus he knows John just loves all that dull sentimentality (except we all know nothing is dull with John...). Let me know if this is completely wrong. Next chapter will be uploaded later tonight, and it will have a bit of BAMF!John :D
Based again on experience; when you read this just imagine the teenage girl with wavy dark-blonde hair and the boy with curly black hair :)
Experiments in Sentiment – One
John Watson could accept a great many things about Sherlock Holmes, including the many traits others would love to see completely eradicated from the young detective's personality. His arrogance was bloody annoying at times but understandable given his massive intellect; his flair for drama was certainly tiresome but never boring; even his experiments were (usually) fascinating.
Something John could have done without was Sherlock's penchant for testing things and experimenting on him. They were invasive, degrading, and/or just plain mad.
Most of the time.
There were times when Sherlock's experiments were beguilingly innocent, like little questions you maybe heard from the mouths toddlers. For example, that time he decided to build an igloo in the living room to see how long it would take to melt, or when he honestly had no idea what the term 'French -kiss' implied… though honestly that last one ended up being anything but innocent.
Today, Sherlock's experiment was simple: Sentiment.
The blogger and the detective were walking the path of a park when the latter, drawn by the bubbling sounds of laughter, spotted a teenage couple nearby partaking in some strange behavior… the girl was atop the boys back, kissing the upper region of his neck. The boy was smiling as he ran in a quick tight circle, causing the girls diaphragm to again push out the elated sounds in the forms of giggles and guffaws.
Intrigued, the curly-haired man looked to the man at his side. Doing some quick calculations in his head, he decided.
"John, I'm going to perform an experiment and I require your cooperation."
The shorter man had only a few seconds to look up suspiciously but had no time to react as Sherlock dropped back behind him and proceeded to lie on his back. "Oi, what that hell do you think you're doing?" John tried to shrug the disturbingly light man off his well-muscled frame but the long legs had already wrapped around him like a vice.
Giving a quick kiss to the small space of skin between John's ear and his ashy-blonde hair, Sherlock instructed quietly: "now, spin around, and quickly; my trousers are stretching."
At that John gave a rueful smile… well if that's how it's going to be played…
Eventually the detective himself was reduced to a few quiet gasps (he'd never admit he actually laughed) as John spun in tight circles. That caused the air around Sherlock to tighten and his stomach knot gloriously; John laughed as his legs began to cramp.
Sherlock Holmes would never change anything about his counterpart, and many would agree with him; nothing needed to be changed. So as the younger man gave into the simple joy of sentiment, he relished in the discovery he had just made: John Watson had the surprising ability to cause the genius to forget his entire experiment.
