"John?" Sherlock asked quietly, he was lying on John's bed facing the ceiling with his hands behind his head. John didn't reply, he had heard his friend, but was concentrating on his anatomy homework, something Sherlock should have also been doing.
Besides he thought if it was really important he'll just ask again. He was right,
"John?!" Sherlock sat up to look at the other boy across the room, his brow furrowed slightly. John sighed softly
"What? What do you want? I'm kind of busy, Sherlock." He hadn't meant to sound so angry, but honestly the tall, lanky and oddly attractive boy with his sharp cheek bones and- John stopped his thoughts quickly and shook his head.
"John I need you to help me with something." Sherlock spoke clearly and quickly. John rolled his eyes and continued with his homework
"with what? Your anatomy homework? We have a test in two days, Sherlock and you haven't even opened the book." John tried to be both persuasive and intimidating, but it was no use as his voice broke half way through the other boy's name. Sherlock huffed
"No. with an experiment." Sherlock flopped back down on John's bed before continuing "I've been thinking a lot recently and-"
"You always think a lot." John interrupted, only to be cut off himself by Sherlock,
"would you just let me finish?!" his voice was now slightly higher than usual with something john couldn't quite place, anger? Nerves? Maybe, adrenalin? John turned from his desk to look at Sherlock who was purposely averting his gaze. Sherlock took a deep breath and continued "I've been thinking a lot about… stuff. Things I don't usually think about, and I can't quite come to a conclusion. I have a hypothesis and a, rather small, sample. One willing participant. But I need a second..?" his statement turned into a question as he looked at his friend.
"One, before I agree to anything I want to know what this experiment is,, I trust you, Sherlock, but you once lit me on fire. Two, you have to assure me this is safe before doing anything, the aforementioned fire. And thirdly, with only two participants, how do you propose to generalize your findings?" the worried look on his friend's face did nothing to sooth John's worries about the possible danger of this experiment.
"The population is only one individual, but I was hoping to do the test on multiple occasions with the same two participants, us. That is, if the initial results are… pleasing…" Sherlock blushed softly "it's not dangerous, John. I promise." His voice jumped almost an entire octave and John decided to just agree if it would calm Sherlock down.
"Yes, fine, okay. What do you want me to do?" His own voice was calm and he hoped it would somehow calm Sherlock as well. It didn't. Sherlock's heart beat impossibly faster and he stuttered slightly as the words fell from his mouth, his eyes wide and palms sweaty
"w-will you k-kiss me, John?"
