Commander Spock and the captain walked off the bridge to the turbolift in synchronized steps. Kirk stopped farther from the control board; however, both men reached to press the button for the appropriate deck at the same time. Their fingers brushed together, delivering a small, yet intense buzz of electric shock. If Jim had not closed his eyes, he would have seen the disruption of his first officer's usually neutral features. This physical reaction could only mean one thing as far as the Vulcan knew, but he was too stunned in the moment to believe it.
"Impossible," Spock thought, "but fascinating." In his own shock he had not noticed that Jim had moved to the far side of the lift. He directed his attention back to his affected captain when Jim spoke.
"Oh, Spock," Jim began, struggling with his words as he desperately tried to keep the desire out of his voice, though mostly failing, "When when we… I… it… why… what just happened?" Jim's hands had clenched into fists, and his head had fallen against the lift's wall as he wondered why on earth it had felt so good to touch Spock.
Jim had already been feeling hypersensitive through their whole shift and began to ask himself, "Why did I pick such an attractive bridge crew?"
He would not mind involving himself more personally with any of them, each having something that just made them extremely doable.
Uhura had her attitude, which in itself was hot, and Jim never could shake the ideas of what exactly she could do with her tongue.
Chekov's innocence was just too cute and, when paired with his Russian accent and genius, was simply irresistible.
Sulu, a fantastic pilot and friend, had it going for him naturally. He's Asian and that is almost always hot.
And Spock. Spock remained mysterious and intriguing. Jim knew that they were supposedly destined to be great friends, though it hardly seemed possible, but he paid attention to Spock anyway. He wanted to be closer to this half-Vulcan as he had felt with Spock's older self. Plus, there was just something about those ears and those eyebrows on top of that well concealed power that was just a turn on.
The intense surprise he felt at their touch had belonged largely to Spock, but Jim had no way of knowing it at the time. The long moment it had taken Spock to finally respond had allowed Jim's thoughts to run wild, and he was surprised again to hear his commander's even tone.
"Captain, I am not entirely certain. Your response seems to be a… powerful one. I would like to research the matter further before attempting to make an explanation."
"Okay," Jim said, "But you are going to try, right?"
"Yes, Captain, I will inform you as soon as I have found a satisfactory amount of information about the phenomenon that just occurred between us."
"You think you know what it is?"
"I have an educated guess. I apologize that this has disturbed you, Captain, but we have reached the appropriate deck for my departure. Please excuse me."
"I just want to understand, Commander, that's all," Kirk said, attempting to regain his professionalism, as Spock made his exit.
"I also want to put your fingers in my mouth," he continued in his thoughts which soon returned to his former contemplations. "Is it weird that I'm attracted to most of my bridge officers even though only one of them is a woman?" Jim proceeded to his quarters as he surmised that being a starship captain also meant being sex starved.
