Original prompt: Can I please have a Kirk/Spock exchange to the effect of

"You can't just go around kissing people!"
"Why not? You enjoyed it. Wanna kiss again?"

(... which may or may not be one of Chris Pine's lines in the Princess Diaries 2)

Yes, OP, yes you can. Here you go. Disclaimer: I own absolutely nothing represented here.

The Fountain

"No, no, you and Miss Uhura make a lovely couple," Kirk stated lightly, watching their respective dates for the ball walk away chatting. He wasn't too into the whole function thing- it was a big garden party, with finger sandwiches and sunhats and shit (but damn those finger sandwiches were good!) And why, one may ask? Well, Starfleet could be simply pointless sometimes.

Whatever, this was a great opportunity to come onto Spock. Why, one may ask again? Well, Spock was really fuckin' hot.

... Okay, no, that wasn't why, but it was still a pretty damn good reason.

The real reason was the Enterprise. It was the best ship the 'Fleet had to offer, and James T. Kirk sorely wanted it. The only obstacle in his way was the unflappable First Officer Spock, first in line to inherit the Enterprise from Captain Pike. However, Bones and Kirk were ready to deal with this; there was an amazingly useful (yet just as amazingly archaic) law regarding Captains: if above the age of twenty-five, the Captain of the Enterprise needed to be married. Spock was twenty-six... And Kirk had just turned twenty-five.

So it totally made sense: he would seduce Spock until he was too "emotionally compromised" or whatever to marry the pretty girl he had snatched up as his betrothed. She was really a class-A girl; gorgeous, smart, witty, gorgeous, multi-lingual, gorgeous, and... yeah, she was really fucking pretty, did he mention that? Still, Jim was every bit as handsome as she was pretty, and he exuded 25423 times more raw sex appeal, if he did say so himself.

Which brought him back to the present: another attempt at seducing Mr. Spock, drawing the Nyota card as the African lady walked off with his own Orion date.

"Thank you, Mr. Kirk," the Vulcan answered flatly, not even twitching in the slightest.

"Mm. Shame you're not turned on by her." With that, he promptly turned and walked away as Spock froze, eyes widening in surprise that he'd later deny.

"Excuse me, I must strongly protest to your statement. I should like you to be aware that I am indeed attracted to Nyota."

"Oh really? Please."

"Indeed, I am. She is aesthetically pleasing, intelligent, empathetic-"

"Empathetic? She understands you, great. But I didn't hear you mention love," he snapped, turning when they reached the fountain to flash the Vulcan a smirk. He received a cocked brow in response.

"You are simply jealous of the connection we share." Spock stated coolly, walking past the human. Eyes widening- he was losing the argument, dammit, he was slipping, his advantage was slipping- Jim grabbed onto the other's arm.

"Why would I be jealous of her? She has to spend the rest of her life with you!" he exclaimed without thinking.

Spock turned, and something in the way the light shone off his eyes made him look outraged. Calmly, collectedly, he stared his companion in the eye and said: "I believe I loathe you."

"Well, I loathe you!" Kirk retorted, tugging Spock closer so they were almost flush.

"I loathed you before you were able to formulate similar feelings towards myself," the Vulcan replied, pausing only when he realized how close they were to one another. There was no breathing room, and if Jim tilted his head upwards just so and shuffled a bit closer-

There. Burning heat against his lips, going straight from his mouth and pooling in his groin. With a low groan, he released the Vulcan's arm and wrapped himself around the other as best he could- one arm around Spock's waist, the other over his shoulders, buried in his immaculate hair. And he definitely wasn't hallucinating when he felt those perfect double-bow lips move against his, fingers creep up his sides, an answering pressure against his hip, ohfuckyeah--

He blinked owlishly at Spock, licking his lips without thinking. The other man looked ruffled, and pretty damn well-kissed, but seemed to also be approaching outraged (again).

"Is there a mutation in your brain that disallows any form of decency? You cannot engage in such intimate displays with people, particularly not those who are engaged." It sounded calm, but at the same time was most definitely veering on the edge of yelling; Spock was backing away from him, walking around the circular fountain.

Never one to give up (and fuck that had been hot, he'd kill to do that again), Jim followed.

"Why not, you enjoyed it- d'you want to kiss again?"

"Well, I-- excuse me? Of course I do not. Cease attempting to cloud my judgement."

"What's confusing about a kiss?" That might've been the wrong thing to say, because Spock suddenly turned so he was stepping backwards, eyes narrowed and eyebrows furrowed. Shit, he knows-

"You are attempting to foster romantic feelings between yourself and I so that I end my engagement and you are free to claim the Enterprise!" It was stated in an even tone, but the undercurrent of emotion made it extremely eligible for exclamation status. Thinking fast as Spock turned on his heel, Jim jumped forward and twined an arm around the Vulcan's waist, pulling him back so they were flush. Remnants of his arousal pressed to the other's hip and he nearly groaned again, but instead chose to play it smooth:

"Maybe I am," he purred, leaning close, "or maybe I just like kissing you."

And looking back, he probably shouldn't have done what he was about to do: he licked the tip of Spock's ear.

The ensuing shove sent him flying backwards towards the fountain, with all to stop his falling form being the hand clutching Spock's arm. Said arm didn't stop him at all; instead, they both flew into the water.

"Spock," he gasped, bobbing up for air and shoving his hair back, reaching for the other. To his dismay, the Vulcan had already stood, and even dripping wet managed to display a dignity that Jim was sure he lacked at the moment.

"I have formulated an excellent idea in the past second. Why do you not duck underwater once more, and I shall count to one million." With that, he stepped smartly out of the fountain and walked away.
