Prompt: How about a jealous!Sherlock Sherlolly fic? Like, when Molly starts getting close to John [as friends of course] and it sparks a jealousy inside Sherlock that he hides under his usual Sherlockian indifference. I love jealous!Sherlock! But somehow, this became slightly possessive!Sherlock... Anyway, hope you like this! :DDD

To be honest, Sherlock was not liking what he was seeing.

True, he had not liked seeing anything that involved two people laughing and chatting in high spirits since his school days.

But this was John and Molly.

And his dislike went tenfold at the sight of them together.

Watching John say something amusing was pretty much normal. Sherlock enjoyed his quip about the different ways he would dump the detective's body if he ever saw another human arm on the dining table. Too ambitious, he had said to John, chuckling. The doctor had then wanted to show him one of his 'bad days'.

But seeing that what he said had made Molly giggle…well, he was somehow wishing John had told her where he would dump her body instead.

Sherlock could not take it anymore when another laugh erupted from the pair. He stomped over to them and was slightly livid when John held on to Molly's arm for support as he was laughing as hard as her.

He stopped by their sides and yanked his flatmate's hand away from her. "I believe this is a breach of a rule we've agreed on," Sherlock hissed through gritted teeth.

John's laughter subsidied to be replace with bafflement. "I did? Since when have I breached a r-"

His eyes hardened suddenly, realising something. "You did not just make the rules while I'm away again, did you?!"

"I don't know. Were you away?"

John rolled his eyes and decided to humour his eccentric friend. "So what 'rule' have I broken this time?"

Sherlock got between them and grabbed Molly's shoulders. She let out a soft squeak at the contact and he spun her around to lead her to where he was working earlier on. Before they moved away, Sherlock looked over his shoulder and growled at the blond, "Molly is my pathologist. You're not to touch anything that belongs to me, remember?"

John shook his head and gave a wry smile as they both walked away. Sherlock certainly was very protective about what was deemed his.
