"No."
"But dad, it's just for a week!"
"No, Hamish. I know how incompetent your public school teachers are and I don't want you in the middle of Scotland without me or Sherlock nearby. Who knows how many more mass murders your school has hired? My decision is final," said John and turned to his paper.
Hamish resisted the urge to scream. "It was one time! Besides, father caught him before he killed anyone," he said dismissively. He tried to be cute. "Daddy please-"
"No and don't act cute with me."
Hamish huffed and turned away, sulking. At that point, Sherlock came into the room looking thoroughly distracted.
"John, we have a case-," Sherlock paused to look at his usually cheerful son. "Hamish, what do you want that John is refusing? Is it about that trip to Scotland or the expensive bicycle?"
Hamish smiled sheepishly. "Trip to Scotland."
Sherlock gazed at him, unblinking. "You can go if you promise to clean your room every day and convince your teacher to stop hitting on John. If the woman is too stupid to understand that he's married then she's too stupid to teach you." Ignoring John protesting and choking on his tea in the background, he continued. "Go pack, you leave in two days. I'll give you the money and sign the permission slip tomorrow."
Hamish lit up like a Christmas tree and jumped to hug Sherlock. "Thank you father, I love you." He stuck his tongue out at his dad and ran out of the room.
"Who would believe that boy is thirteen?" grumbled John. "And Sherlock you can't undermine my decisions like that, who knows what trouble he'll get up to in Scotland. For Christ's sake, he worries me enough in London."
Sherlock scoffed. "You underestimate our son, John. He'll be fine and besides I have friends in Scotland that will keep an eye out for any shenanigans. At least he'll leave us alone for a week."
John choked on his tea one more time as Sherlock ran a hand down his leg, suggestively. He let out a strangled groan when his hand wandered too close to his crotch.
"Not when Hamish is home," gasped John.
"Oh yes, please. I'd like to go through my life trauma-free, thanks," snickered Hamish from the door.
"Son, you better stay at a friend's house tonight if you want to be 'trauma-free'," said Sherlock and kissed John gently once, twice, before John pulled him down for a real kiss.
Hamish wrinkled his nose and left mumbling something about 'horny fathers' and 'if Alex Lestrade would let him stay over.'
