"So I was thinking," John began, licking at the mint ice cream he had in his hands.
They had just returned from grocery shopping on the cloudy Saturday afternoon.
A smirk twitched at Sherlock's lips. He vaguely tried to contain his snide comment but could not stop it from slipping his mouth: "This should be good," he chided. He was searching something related to old-style unicycles on his cell phone, but he let his smirk fully develop when he saw, from the corner of his eye, John glaring at him.
"Very funny. I was just thinking about the bicycle case, and I remembered how some children at my school used to attach playing cards to their bikes. So I was thinking –"
"We check Sir Willow's house for card sets," Sherlock interjected matter-of-factly, and swiftly he whipped out the set of cards in question from his coat pocket.
John looked at him, befuddled, then asked "how did you- never mind."
He cut himself off almost immediately, shaking his head, and continued, "so, any conclusions then?"
Sherlock jumped on the invitation to divulge his thoughts.
"I have a few in mind," he said, "but first, I need to test a theory of a… different case."
At that moment, John's retro MSN beep sounded on his phone to signal a new message. He stopped mid-ice-cream-lick and fumbled around, balancing the two shopping bags of groceries and his ice cream in a circus of precocious physics.
Taking his opening, Sherlock suddenly bent down a tad, tilted his head, leaned in, and licked a spot of ice cream from John's lips; like a viper and its prey. And just as quickly, John gasped and retreated like he had been struck; dropping all he was holding except for his cell phone, which he had been taking out of his front pocket.
"Sherlock wh- what… What was…" he took a deep breath, steadying himself physically and mentally, "What the hell was that?"
Smirking, Sherlock strung out his reply slowly, in a tantalizing sequence of words.
"I was testing a theory I had about you. I sensed that there was some… Tension between us. Sexual tension."
Sensing the objection forming on John's lips, he decided to silence it. He reached up and placed his thumb on John's bottom lip, stroking it for a moment before gently leaning in to touch their lips together. Sherlock raised his eyebrows as he felt some lip movement from the opposing side, but then he was pushed back lightly. He looked down as innocently as he could into John's troubled eyes.
It looked like John started to say many things, but couldn't decide on what to say. Finally, he turned and walked five steps away from Sherlock and took out his phone. John couldn't help but chortle a little out loud when he read the message that he found:
I like you too.
