"I don't have detention today," Sherlock told John proudly.

"Wow, for once in this entire year?" John teased, reaching up to touch one of Sherlock's inky curls.

"Oh, shut up." Sherlock captured John's hand in his, intertwining their fingers together like ribbons on Christmas. John tugged silently at the sleeve of his jumper.

"You've never touched my hair before," Sherlock whispered.

"Its's...nice," John blushed as they made their way to the doors of the school.

"You're nice."

"That was such a witty response. Good job," John teased, dipping his thumb into the crevices between Sherlock's porcelain knuckles. He wondered what would happen if he kissed them instead.

"You're such a sarcastic bastard sometimes." Sherlock squeezed their palms together. Heat filled the tips of John's fingers and spread all the way down to his toes, igniting his bones with sparks he never wanted to extinguish.
