They didn't talk about "the incident" as John referred to it, and he was thankful that Sherlock had decided not to allude to his slip up. He couldn't believe he'd had his lips on Sherlock Holmes!
Still, that didn't mean that he wasn't thinking about doing it again. He berated himself for doing so as Sherlock was currently a patient under his care, and he should be more concerned about his health and recovery than his dark curly hair that framed his beautiful pale face.
Sherlock must not have found "the incident" to be disturbing or strange because he made no move to avoid John. In fact he seemed to move closer to him. One night while Sherlock was gripped in the pain of withdrawal he grabbed John's hand and refused to let go all night. When John woke up he was laying in Sherlock's bed while the detective slept, his head placed on top of the hand he had claimed.
John watched the pale man breathe in and out regularly and found himself entranced by that simplest of things. It was only when he realized that he was watching Sherlock sleep that he shook his head and pulled himself out of the bed. He didn't wake Sherlock as he went. Even though Sherlock very very rarely slept, when he did sleep he could hardly be woken by an explosion.
John stared down at his hand as though he could see some sign of Sherlock there. He could still feel the heat of Sherlock's cheek, and he realized that he wanted nothing more than to climb back into the bed and press his forehead against Sherlock's so he could feel his heat again.
