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 1: An Idea is Conceived

The USS Enterprise, gleaming white in space's darkness, drifted above Vulcan Beta, a burning planet, now the replacement home for a species known for restraining their fire, quenching it, even. With the help of the crew that saved the world, the Vulcans reestablished themselves on their new planet. Of course, near the end of the rebuilding, a glitch struck the Enterprise, requiring the crew to stay for longer than they expected, getting more tans and/or sunburns than they expected.

Spock stood beside Jim, his bondmate, as they accepted the thanks of many Vulcans, including his father, and the version of him from a happier reality. A happier reality, one where Vulcan never exploded, where Jim's father lived longer than in this one. One where 'endangered species' never was a term to apply to Vulcans.

His other self spoke, only making what-Vulcans-should-never-have worse, compounding the tragedy. Spock attempted to meditate, something perfected by Vulcans, a crucial part of emotional restraint. It worked, at least until the other him said, "Our species is known for eradicating our emotions. The power of them can destroy us. Yet, there is some value in them, particularly in the one known as love." He paused. "Acting on love, even if it destroys you, is worth it."

Meditating interrupted; Spock's eyes wandered over to Jim, the focus of his love, who returned his gaze with concern, decoding what Spock meant to hide, sensing his feelings through their link.

Then, he donned a cocky smirk, one reminiscent of when he illicitly reprogrammed the Kobayashi Maru in order to make winning a possibility. Spock considered that puzzling, wondering at the apparent mood swing.

Jim neared him, saying in that raunchy tone of his, "My love, how about we go to my quarters and put our mouths to use for more than 'you're welcome's? Let the rest of the crew get their due… What I plan on doing to your ears will be so hot that… you'll wonder if there's a law against it."

Spock raised his eyebrows, replying, "That sounds most agreeable, however, remaining for the entirety of the Vulcans' 'thanks' might be necessary for reasons relating to diplomacy and politeness."

Jim groaned, catching Spock in a Vulcan kiss. "Prepare for a surprise, my awesome stick in the mud."

Spock expected sexual visions, fantasies involving intercourse, the mental equivalent of the Earth fad known as 'sexting', instead he received one of his Jim's fascinatingly intelligent and 'crazy' as humans – particularly McCoy – said, occasionally rule-defying ideas. There's a way to give you a part in repopulating Vulcan. It's illegal, but whatever. I'll tell you more in my quarters.

Fascinating, Spock replied through the link. If you fabricate a viable way to explain our leaving to everyone else, we might be able to do it immediately.

Gladly, Spock, Jim teased. You know I'd do anything for you!

Jim glanced at his PADD, faking the expression typical for humans informed about duties that need doing. "Spock, there's an important Starfleet matter we need to discuss. Just us, in my quarters." He paused. "Sorry, ambassadors, crew and citizens!"

The Vulcans told them, basically, that since offense was an emotion, making it illogical, they were not offended. The crew reacted in a variety of ways, though some crewmembers didn't notice or react at all. Either way, permission did appear to be granted.

As soon as they both were sure, they headed off to Jim's quarters, neither of them ahead of or behind the other, being beside instead. Just walking with Jim thrilled Spock, though 'thrill' was yet another emotion supposed to be foreign to him. His t'hy'la brought out what Surak's philosophy said should not even be there, yet when he was with Jim, logic meant a bit less and love meant more.

Spock occupied his mind with thoughts of Jim, equations and his work on the Enterprise until they reached Jim's quarters. Once they reached there, Jim became the sole focus of his thoughts.

"Please inform me about your proposal of a way for me to aid in increasing the Vulcan race. If it involves intercourse with anyone other than you, I suggest that you do not bother."

Jim blushed, practically stuttering out, "No, this 'proposal' doesn't involve any sex, though I could give you what you thought I was suggested before, as well."

Spock replied, "Continue."

"Alright," Jim responded, smiling. "But first, I need to do this. Computer. Music. Pop. Songs about sex. Loud."

"What is the purpose of the music?"

"We're planning on something illegal, so it is only logical that we prevent the rest of the crew from hearing us."

"Most logical," Spock replied, with what Jim called an 'almost-smile.'

"Okay, I plan on getting a non-Federation species to help genetically engineer a baby for us."

"Fascinating notion," Spock responded. "However, are not most non-Federation species unfamiliar with us or our enemies?"

"And Klingons tried to integrate Terran super-DNA into themselves and some of them lost their ridges," Jim replied, groaning. "I know about the difficulties, but there's no such thing as a no-win situation."

"Yes, you do believe that," was Spock's reply. "I admit to lacking that belief, though you always seem to prove me wrong about it."

"T'hy'la, dude, I have a way to avoid that difficulty," Jim responded. "You know how good a programmer I am from the Maru, right? Well, I bet I can come up with a program that can search the computers for information on genetic engineering and non-Federation species; constructed in such a way that no one can tell who is looking for the info."

"Yes, I am sure that is not beyond your abilities," Spock responded.

Jim continued. "And I have at least three alternate accounts that the program can send it to. No need to worry about our research popping up when others are capable of reading it, unless someone hacks my PADD, accounts or something."

Spock kissed Jim, the Vulcan way, feeling his fascinating thoughts and pleasant skin. "Intelligent and logical of you. As always, as it has been since I met you, your mind is a source of fascination for me. Your scheme seems likely to succeed, t'hy'la."
