Sherlock had John pinned against the wall, holding both of John's hands against it, above his head, while his other hand caressed his jawbone lightly.
"Sherlock... people are staring!" John hissed.
"Oh, let them stare." he chuckled.
He leant in and kissed the tip of John's nose, still holding him against the wall with his hand, and with his body.
The hand at John's jawbone slid down to his neck, and he caressed the crook in his neck, before moving back to just under his jawbone.
His fingers lightly tapped John's neck, making John shiver.
"Oh god Sherlock. Don't do that if you don't intend to do any more!" he whispered urgently, lust filling his voice.
"Who said I didn't intend to do any more?" Sherlock whispered into John's ear, his warm breath tickling his inner-ear. John shivered again.
His hand slid round the the back of John's head, and he leant in, kissing John lightly.
John could practically feel the hormones tearing through his body, accompanied by intense lust.
"I... nnngg..." he groaned.
John's head was tilted upwards, and his lips accepted Sherlock's as if they were two halves of a pair.
He spoke when their lips were apart for long enough.
"Oh god... Sherlock please... not heeeeeeere!" he tried to keep his voice down, and failed miserably.
"Oh, John, don't spoil my fun." he purred.
John could feel his erection straining against his trousers, and Sherlock ground against him, rubbing both their hard-ons together. John was still taking the kisses off Sherlock, but grinding in public? No; too far.
He pulled his lips away from Sherlock and pushed him away.
"That's too far. Grind all you want at home, but not in public!" John hissed.
Sherlock rolled his eyes, and stepped back to next to John.
"May I kiss you still?" he asked.
John nodded.
It seemed that Sherlock really needed this. He really needed the comfort of romance off of John.
John made a decision.
"We're only a couple of streets away from home... if we hurry..." he left it hanging in the air between them.
Sherlock grinned, and grabbed John's arm, pulling him along.
John grinned.
Tonight was gonna be good.
