Why this must be read:
This fandom has the best kisses. This is an odd one. It's Sherlock watching John kiss Sarah, from the shadows, and thinking.
Just thinking, mind.
It works wonderfully as a Sherlock POV story, too, which also enrich the fandom. He's such a fascinating character through whom to write.

***
There was nothing for Sherlock in that kiss. There was nothing to deduce; it was all so painfully apparent, writ boldly, like a grave or like an infant, like more than six billion people Sherlock was often trying to forget. There wasn’t any hint in John of Sherlock, some mark Sherlock had made, some reluctance Sherlock had elicited, some second thought or hidden longing. There was nothing in that kiss of Sherlock under the streetlamp, of Sherlock’s heart, beating so hard it should have bruised the ribcage, if such things were possible, of the way he couldn’t seem to breathe right—straight up through the nose; that was the way these things were done, Sherlock; any living human brute could do it, and animals too; ants did it through their bodies because what they needed was in the air, the air, the oxygen’s right here, right here, can’t seem to get it; there was nothing of John taking away Sherlock’s oxygen with his mouth and breathing it back into him, breathing life back into him, making everything okay.

There was nothing of the way John and Sherlock would have kissed.

I could make him, Sherlock decided. If I wanted to.
