Sherlock's eyes fluttered shut as he surrendered to the sensation of John's thumbs stroking across his cheekbones, the feel of John's lips still imprinted where they had blazed a trail across his, and the warmth of John's breath as his spoke.
"Have you fallen asleep down there?" There was a huff of laughter in the question as John's thumbs lightly caught at the edges of Sherlock's lashes.
The doctor gently pulled him close once more, and this time a questing tongue edged between cupids bow and full lower lip begging entrance, then once granted, tasting and teasing.
Sherlock groaned, leaning into the kiss, his limbs feeling heavy as he let his hands slide along John's thighs, blindly groping for the other man's hips.
"Shhh, gently. We need to get some rest if we are to find Greg and Sally, and help your brother."
"Sorry, I'll….. I'd better turn in." He started to pull away.
"Come back here you git! We need to rest, but that doesn't mean separately." John stood and pulled Sherlock to his feet. "Your room I think, nearest."
In silence they entered the room, and stripped down to their underwear. Slipping under the duvet they naturally gravitated towards each other, wrapping around each other as if from habit, and in the warm darkness forgot about the trouble beyond.
