So, after all the happy fluffy johnlock, I wrote a dark little fic:

Night Dark Like Bruises: John’s been rescued, but he’s badly beaten. Sherlock comforts him, then seeks to release his anger in the night.

Stuck a graphic depiction of violence tag on there, I don’t think it’s that bad, but if you’re sensitive, you might want to skip this one.

Sherlock stopped in the doorway to Johns room. He lay in just his pants, mercifully asleep after the night he’d had.  A gash showed along his temple and his bare back and shoulders were covered in bruises, trailing down to his thighs and even a couple on his calves. The wrists were still raw from where he’d been bound. Sherlocks fists clenched as he remembered finding John

All the evidence showed John had been beaten after he was bound. Lestrade made no comment when Sherlock had quietly broken the kneecap of one of the men. He’d insisted on taking John home to rest, deducing most of the wounds were superficial.

Raising his head, John regarded Sherlock. “Just going to stare?”

Sherlock dropped his dressing gown and crossed the room. Crawling across the bed he nudged John’s legs apart and leaned over his battered back to kiss his neck. John groaned, then whimpered as the kiss turned into a bite.
