Again written for a drawing. It's that one of John and Sherlock pressed against a wall in the moonlight - if you know what I mean.
"No, Sherlock." John hissed. He could feel the wall press up against his back as Sherlock forced him against it. He didn't have room to move with the detective in such a close proximity. Skin almost touching. It could feel the air escaping Sherlock's lungs. "The case!"
"The case is basically over, John." Sherlock whispered. His voice carrying only as far as John's ears. John's heart rate increased. He wasn't sure if it was from fear or excitement. Not just yet anyway. Again, Sherlock was correct. The case was basically over so there no point trying to use that as an excuse. Something within him was worried.
"Sherlock. Please." His eyes firmly clamped shut to avoid giving Sherlock the terrified expression he no doubt would show.
"You're afraid. Of this. Let me tell you something, John." Sherlock leaned in closer. John could feel the slight shake in his body. Sherlock never shook. He could sense Sherlock face nearly touching his. The noses just slightly brushing. "So am I."
Quickly Sherlock leaned in and placed his lips firmly upon John's. For a few small moments there was no reply. John stood there in bewilderment until he felt a warm pass through him. It felt pleasant. Not like he expected it to be. His worst fears weren't coming true. This was real and normal and there was something that made him want more. John began to kiss Sherlock back with mutual affection until the oxygen in their lungs had completely disappeared. For a second they remained there silent, noses touching and hearts bounding.
Finally opening his eyes again John became aware of the dark London city around them. Cars honking and street lights hidden. Sherlock was looking down at him. A smile tugged at the corner of his mouth. "We should get back, Sherlock."
"Later," John felt his hand interlock with Sherlock's. "Let's go home. We can get to the case tomorrow."
The only thing John could do, as he was felt himself being dragged through the oddly quiet London streets, was silently agree. The case could definitely wait.
