A/N This is my first 221B. I'm happy, it's sweet, and I hope you enjoy it too ^.^

Disclaimer: I do not own Sherlock. If I owned Sherlock, and by default Benedict Cumberbatch, I would not be in my bedroom writing fan fiction. I would be in my bedroom doing other, more interesting things.

The Mistake - 221B

Mycroft had tried keeping them apart. He'd seen how trust in someone made Sherlock more reckless. When bribery hadn't tempted John Watson, Mycroft advanced to stalking him. Unnerving him. But John was an army officer, so when intimidation, and then blackmail also failed Mycroft decided to played dirty.

It was a small matter of calling in some favours that got John called out to a medical centre in Afghanistan; helping soldiers who were being invalided home and as far as Mycroft was concerned that was the end of things.

What he hadn't taken into account was Sherlock's genuine attachment, and the fact that his brother would never forgive him for this error in judgement unless he fixed it. Quickly.

It had taken Sherlock mere hours to find John's location.

Sitting at his desk, watching John's muscled arms wrap round Sherlock as they reunited in a tangle of legs, and sweat Mycroft sighed, shutting down the camera's for 221B.

Sherlock chuckled as the camera light flickered off, swiftly followed by a sharp groan as John thrust against him growling, pulling Sherlock's orgasm from him at startling speed. As they calmed and clung to each other, John heard Sherlock's murmurs as he drifted into a post coital daze.

"You really here, John?"

John smiled sadly, "I promise you, Sherlock... I'm back"
