"Again."

Sherlock did it again.

Tiny giggles.

"Again."

Sherlock did it again.

Tiny giggles.

"Once more, pleeeease Daddy."

Sherlock did it once more.

Tiny giggles.

"Ok, no more."

"Pleeeeease."

Sherlock did it ooooooone last time.

Tiny giggles.

Ten minutes later, Sherlock and Ian were in Ian's bedroom when they heard John get off the couch. They paused and listened as John stood and stretched, marched to the bathroom, opened the door, clicked on the light, and yelled.

"Sherlock!" he called.

They scrambled as they heard John exit the bathroom, trot across the living room floor, lunge up the stairs, and storm into Ian's bedroom. John heard snickering from the closet, and instead of confronting them, he left them in there for forty-five minutes, then spent another hour giving them the 'half-playing-along-half-really-angry' silent treatment.

That was the last time Sherlock and Ian drew on John's face as he slept.
