Title: Child of Two Worlds

Author: unknown20troper

Rated: T

Warnings: slash, innuendo, probably some swearing,

Pairing(s): Kirk/Spock, some Sarek/Amanda and George/Winona

Summary: For most Vulcans, increasing their population is as easy as copulation. For Spock, it is much harder, impossible, in fact. Hybrids are infertile and Kirk can't, as far as Spock knows anyway, get pregnant. However, Kirk has a way, an illegal way, to give Spock a part in the efforts to return his species to their former numbers. 'Cause he just doesn't believe in no win scenarios.

Notes: Constructive criticism welcomed.

Chapter 2: It Develops

Jim picked up the knight on the left placed it two platforms away from where it started. He flashed a grin at Spock. "Awesome, isn't it?"

"Actually, that move is rather reckless," Spock responded, moving one of the movable platforms closer to his t'hy'la's knight. "Illogical. Yet, I can almost see how it might work."
Jim smiled. "So, you don't think it's a no-win scenario?"

"I suppose so. It is your move and I already approved your plan."

Jim smiled, eyes twinkling with laughter as he imagined Bones' saying, "The hobgoblin plans your chess games? Crazy Vulcans." And then, of course, he might just explain what Spock really was talking about.

"Great. This is for you and the Vulcan species, after all." He winked at Spock, and returned to assessing the 3D chessboard, looking for a good move, an illogical one that would screw with his Vulcan's lover's mind.

"Are you saying that you will derive no benefits from it, t'hy'la?"

"Maybe, but as I said, I'm not doing it for me. I'm doing it for you." Jim noticed that Spock's emotional side (which his species said he shouldn't even have, but fuck it, emotions aren't that harmful, even for Vulcans) wanted the inevitable result of the plan to have a favorable impact – Spock probably wouldn't say 'pleasing' or any other word that is very related to emotion, Jim supposed, considering the Vulcan philosophy – on both of them.

"Jim, I am aware of that. Yet, if this scheme and its results only will have a detrimental effect on you, I refuse to let us go through with it."

"Don't worry. I'm James Tiberius Kirk, you know. I can handle it." Jim sounded casual, projecting confidence as he had done many times before. "No-win scenarios are impossible, remember?" Then he sighed, letting himself show the feelings behind his casual air. "And I love you. This plan may risk my life, safety and status, but hey, you're worth all of them, t'hy'la."

"Yes, you are, and based on our previous experiences, I hypothesis that you probably can 'handle it.' Yet, since logic tends to abandon me when I am around you, I did not consider that." Spock examined the chess platforms, and then lifted his gaze back to Jim. "That is a very flattering assessment. Such statements show that emotion has its advantages, and I am rather… contented by the knowledge that to you, I am just as important as the needs of the many."

Jim's illogical recklessness seized him as soon as Spock finished speaking, causing his desire and love for his t'hy'la to manifest as a powerful kiss. His mate responded by doing the Vulcan version of what Jim had just done, making it all even better.

They neglected the chess game and expanded the kisses into something more physical than chess. Luckily, Spock's Vulcan memory was so much better than Jim's human one and the game was being played in Jim's quarters, so if they desired to continue playing after acting on their other desires, they could.

After engaging in full exploration of each other's bodies, they both remembered that the intimate activity was not the only thing on their minds before and could not be the only thing occupying their mind after it either.

"You know, if the sex we've been having produced babies, we wouldn't need my plan." Jim smirked. "We'd already have too many of them to count."

"Your statement is illogical, but I understand the sentiment that created it. We do engage in quite a bit of sexual activity and your plan is an unusual but necessary way to reproduce."

"Uh, yeah, you could put it that way. Anyway, the Enterprise isn't the right vessel for this mission. 'Cause if the flagship goes off to do something unsanctioned by Starfleet, they probably will notice, and hey, I'm not going to involve the entire crew in this."

"The Jellyfish, the ship of my alternate self, would be a logical choice. It is more advanced than any other ship in the fleet and Starfleet is unaware of its existence. Only my alternate self will notice if it disappears, and I am sure that he will understand the reasoning behind your actions."

"Very logical, Mr. Spock." Jim smiled. "If Vulcans weren't emotionless, I would say that they would be proud of it."

"And if Starfleet did not disapprove of genetic engineering, I would say that they would admire your scheme. However, neither the Vulcans nor Starfleet would consider this to be anything other than an violation of the Federation's laws." Spock paused. "Yet, their opinions do not and should not change my own."

"That's okay. But, do you think we should let Bones in on our plan?"

"Yes, though if we were to inform him before we know enough, he may consider it a mad idea and wonder if you are out of your human mind and I am out of my Vulcan one. However, he is your friend and despite how inclined he is to mention it when your ideas are 'batshit insane', as he says it, he always participates anyway, after making any necessary modifications."

"Astute observation, Mr. Spock," the captain replied, in the same tone he'd use on the bridge. "How about we tell him together?"

"That would be agreeable," Spock responded. "Perhaps we should do so now, before we become entangled in our duties and even more of the planning required for this."

"Great." Jim smiled, sliding himself off the bed and regaining footing on the floor.

Spock followed him off, and commented, "Of course, we will need to dress before we see him. Dr. McCoy is only supposed to see us nude when it relates to his medical duties, and I doubt he is interested the rest of the time."

The couple began to dress, positively affected by each other's presence, and recent discussions and actions; readying themselves to face their friend's probable reaction.
