A/N: Hello lovelies! So I thought this might make a good oneshot, but I could extend it if you want. If you read this I'll pay you in kittens. (Or cookies, whichever you prefer.)

Disclaimer: If I owned Sherlock then Johnlock would be a serious, serious thing by now. All credit goes to the BBC and the incredible Sir Arthur Conan Doyle.

Yo Ho John Watson

"John, look! I'm a pirate!" the boy hanging upside down from the (thankfully) sturdy-looking tree branch yelled. "Look, look at my costume!"

John chuckled delightedly, his laughter ringing through the grounds of the Holmes manor, and reached up to pull himself onto his friend's perch. "No no, John! First you need some pirate clothes!" the boy gasped excitedly as he scrabbled at the branch and manoeuvred himself into a more gravity-friendly position, his flushed cheeks returning to their usual ivory pallor. "A, a scarf, and a hat, and a pirate sword just like mine!" He jumped down, landing as always with grace and agility, and stood up to face his best friend.

"Do I not get an eyepatch?" John queried, his face falling slightly. Everyone knew that the eyepatch was the best part of being a pirate.
"Well, I only have one in my dressing-up box… but John, here! You can have mine!" The boy leaned in eagerly, his dimples presenting themselves on either side of his rosebud lips and eyes crinkling like a starburst as he held out his treasured eyepatch. "It's okay, I don't mind one little bit."
"Oh no, Sherlock, I can't. It's yours; you love your pirate eyepatch."
At this, Sherlock looked him right in the eyes and said solemnly; "Yes, John. But I love you more."

John's eyes widened and he leaned in even further until he was almost nose-to-nose with the older boy. So close he could count every single one of those sooty lashes as they cast a beautiful and delicate shadow across his perfectly smooth cheeks. Sherlock blinked slowly and bit his plump lower lip. "John, I…"
"Shut up, Sherlock." John murmured, resting his flushed forehead on his friend's inexplicably cool one. "You keep it. I love you more than eyepatches." Sherlock's dimples deepened as his mouth spread into an impossibly wide smile. John raised a hand and brushed a rough thumb over Sherlock's lips. "Now let's go and get me some pirate clothes."
