We sat watching the CCTV when a couple stood in the middle of the park, kissing quite passionately. I tried not to watch, finding it awkward. I cleared my throat. Sherlock twisted his lips. I avoided his gaze.

"I've never been kissed," Sherlock said suddenly.

I looked at him for a moment.

How was that even possible?

"Never even for research?" I asked.

"I understand the function," he said, defensively.

I looked at the ceiling, "It's quite an amenable state," I noted.

He looked at me curiously. I leaned into him and pressed my mouth against his. His lips were twice as soft as I had considered. He pressed them cautiously against me. He tasted precisely as he smelled. I was terribly pleased by this. I slid my tongue across his lips gently. He did not respond, so I nipped at his lower lip. He continued to be non-responsive. I pulled away.

"That means for you to open your mouth," I said huskily.

His beautiful eyes were still closed, and his lips were pinker from my kiss. I enjoyed viewing my effect on him. He was flushed and beautiful. Sherlock's pale skin only looked more delicious in contrast to his reddened skin. I kissed him again. As I bit his lower lip, he opened his mouth for me. He placed a hand in my hair, gripping it between his fingers. I traced his cheekbones with my fingertips. He brushed his tongue against mine.

He angled his head to penetrate my mouth deeper, and I slid my tongue across his teeth. He pressed his tongue to the soft pallet of my mouth. Our tongues met once more. I returned to biting on his lips, sliding my tongue across the indentation of my teeth. He moaned and crawled into my lap. I slid my hands to his thin waist, pulling him closer. I wrapped my arms around him, holding him tightly. I could feel him growing hard against my chest.

Oh god.

Sherlock's lips were soft and smooth against mine. The lack of friction was beautiful. And christ, it was stupidly arousing. I could feel him breathing into me, as though he was taking me inside of him. That thought was vulgar. I wanted more of it. I wanted more of him.

But our kiss broke.

"You fucking liar," I said, my voice heavy with arousal.

He grinned.

"I've never performed intercourse either," he said, his breath short.

I didn't believe him, but I was willing to change it if it were.
