enarms:

john letting sherlock see his shoulder wound scar for the first time and sherlock’s fascinated, he spends twenty minutes inspecting it, running his fingers over it, tracing lines from the marred skin down along the tracks where the muscles connect, tracing the places where pain receptors would have lit up and blinded john, marking and mapping until he can understand exactly where john was when he begged god to spare him. john hadn’t been expecting to be the subject of sherlock’s scrutiny, paid closer attention than sherlock’s fleeting inspections of crime scene corpses. he doesn’t have the energy to muster up embarrassment. he stands, lets sherlock work, rolls his shoulder into his hand when it seems like it’ll be helpful, lifts his arm to shift the muscle when it looks like that’s what he needs, and if his fingers brush against a forearm or a leg when he lowers it again, quietly grateful to be the centre of sherlock’s universe, if only for an hour? well, that’s theirs. never anyone mind.
