“Captain’s log; This morning, the Enterprise arrived in the Sepel system, orbiting Sepel II. The Sephins have recently discovered warp technology and are eligible to join the Federation, so we’ve been sent to make first contact. Thus far the Sephins seem friendly- or at least diplomatic. Some still seem on edge around us, but who can blame them? We’re the first outsiders they’ve met.
“Myself and my senior officers were invited to a formal meeting with their high council. We were told they believe pairs are very important, so four of us will beam down. I’m hopeful that we’ll be able to move forward with the Sephins. They have a very interesting culture and seem eager to learn about other cultures as well.”
Jim paused when he heard his door chime. He hastily ended the recording and called for the door to open, still fiddling in front of his mirror with the clasps of his dress uniform. In the reflection he watched Spock enter, all ready to go. Spock could make even the fancy stuck-up uniforms look good. His normal eyeshadow had been accentuated with darker purple and hints of gold, with black eyeliner and mascara too. His hair was even more perfect than usual, not a hair out of place.
“You look nice, Mr. Spock,” Jim said, smiling at his first officer in the mirror.
“Thank you, Captain,” Spock replied. “I am here to remind you that we are due on Sepel II in approximately 12.86 minutes.”
“Got it, just having the usual troubles with this damn uniform,” Jim sighed, still trying to seal his too-damn-complicated buttons. Spock almost looked amused.
“I would think that you would be used to this uniform, considering this is the 17th time you have worn it,” Spock teased, correcting the few clasps Jim had closed and sealing the rest, straightening out a few wrinkles along the way.
“The 17th time I’ve worn it, sure, but every time it seems a certain Vulcan does all the work for me,” Jim teased back. Spock raised an eyebrow.
“If you are quite finished, the rest of the landing party is waiting for us in the transporter room.”
Jim flushed. Teasing Spock was fun and all, but if he was starting to keep everyone waiting he’d have to learn to do it himself next time.
The two quickly made their way to the transporter room, Uhura grinning at them when they arrived.
“Oh, good, I was worried you forgot about us, Captain,” she chuckled. Scotty smiled beside her but held his giggling for a more appropriate time. Jim rolled his eyes exaggeratedly.
“You know how it is, I had to get Mr. Spock on track,” Jim joked, earning another raised eyebrow from Spock. They stood in their places and Jim ordered, “Energize.”
When they materialized on Sepel II, they were greeted by the two tall, thin, blue-skinned representatives they’d met earlier, along with five guards and four significantly older-looking Sephins. They all had a pair of coiled horns on their heads, but the elders had much longer horns, and had decorated them with dangling chains of gold and jewels.
One elder scowled at Jim immediately, sniffing loudly and leaning close to another elder to whisper something, who also glared at him soon after. Not a good sign.
“Honorable council, we thank you for this opportunity. I am Captain Kirk, this is my First Officer, Mr. Spock, my Chief Engineer, Mr. Scott, and my Chief Communications Officer, Lieutenant Uhura.” The four of them bowed to the elders. When they straightened up Jim noticed with some unease that they still seemed to be staring at him strangely.
The tallest elder approached him, his dark blue face wrinkling more as he stood in front of Jim. He leaned in and sniffed Jim, the Human standing stiffly as the Sephin snuffled along, checking his hair, ears, and neck. The elder pulled back and glared disapprovingly.
“You are not one of a pair,” He spat, suddenly furious. Jim suspected there had been a severe mistranslation regarding the importance of ‘pairs.’
Another elder moved in, sniffing the other members of the group. They seemed to accept Scotty and Uhura, but hissed when they reached Spock.
“This one is not paired, either!” They snarled to the tallest elder, firmly grabbing Spock by the arm. Scotty reached for his phaser, but was tackled by one of the guards. Uhura tried the same, with similar results. Jim was grabbed by the elder towering over him, who was remarkably stronger than Jim had expected.
Spock struggled against his captor, who was joined by another elder and two young guards; Jim managed to break free of his own elder’s grip but was quickly shoved to the ground by a representative, and pinned by her and a surprisingly heavy guard.
After a few long minutes of fighting, Scotty and Uhura were without their phasers and communicators, sat together in a corner with their two guards and the other representative standing over them. Jim and Spock’s phasers and communicators had been confiscated as well, and Jim had managed to tear the left arm of his shirt clean off in the scrap. Much more battered than they had been upon arrival, Spock and Jim were dragged away to another room.
They were tossed into an empty, white room, and a purple, glass-like wall flashed into being once the Sephins had stepped out. Jim stood and pounded on the wall furiously, only growing more frustrated as it had no effect.
“Don’t waste our time, Kirk!” the tallest barked. “You must be paired!”
“What the hell are you talking about!?” Jim yelled back, still pounding on the wall. Even if it wasn’t damaging the wall, at least it was pissing that guy off.
“You only smell of yourselves, selfish creatures! You disrespect us, coming here alone!”
“We’re not alone! We came in pairs just like you told us to!”
“Captain, I do not believe they simply wished for an even number of-” Spock tried to interject.
“I am well aware of that, Spock,” Jim snarled at Spock. He turned back to the elders. “But if they wanted more they should’ve said so!”
“We are already giving you your chance to correct this error,” another elder jumped in, sneering down at Jim with clear disgust. “We will overlook this disrespect if you will pair now.”
“How do we pair? Spock and I are together all the time, we’re one of the closest command pairs out there- what more do you need?”
The only answer was a slurry of alien consonants Jim could only interpret as cursing.
“Captain, I believe they are a scent oriented culture, and would therefore consider us paired if we carried each other’s scents,” Spock supplied.
“Oh yeah? Is that what you stringy bitches need?”
“I do not believe insulting them will help us-”
“Answer me, dammit!” Jim pounded on the wall again, openly enjoying the angry twitch the action earned him from the tallest.
“You foolish, disgusting, savage little brute of a creature-” the tallest hissed, his insults devolving into more enraged nonsense the translator couldn’t figure out. “Yes! You must carry each other’s scents, it is obvious!”
With that, the Sephin at the control panel for the cell pushed some buttons and the room dimmed significantly, the Sephins gathered outside of the cell dispersing until only two guards remained.
“Okay- fuck, fine,” Jim turned back to Spock and grumbled. “How do we do this?”
“As a Vulcan, my body has multiple scent points with much higher scent concentration than that of a Human. As such, I am easily able to mark you with minimally invasive procedures. However…”
“However?”
“As I had already mentioned, Human scent points are much more subtle, enough that I am unsure whether they could meet the Sephin’s expectations.”
So what, if I’m not stinky enough we’re fucked?”
“In… in a sense, that is accurate.”
“Alright, then… What are our options? Assuming I can even do this.”
“I believe you would best be able to mark me if you were to exert yourself to the point of perspiration.”
“I just need to sweat? That’s easy enough.” Jim started jogging in place, lifting his knees high in an attempt to wear himself out faster.
“Perhaps it would speed up the process if we were to spar," Spock suggested. "I have noticed you begin to sweat within the first 10 minutes of approximately 84% of our sparring matches.”
Jim shrugged. “If you say so,” he huffed before promptly charging into Spock, dropping the Vulcan to the ground, and climbing over him. Spock easily flipped their positions, attempting to pin Jim’s hands and straddling his hips. Jim gave a good shove against Spock’s hands, pushing him back enough to sit up. He managed to roll them over again so Spock was on his back, and he pushed his hips hard into Spock’s in an attempt to keep him in place. He didn’t take into account the way Spock’s legs were spread, and accidentally dragged his cock over the soft mounds of Spock’s sheath. Jim’s pants suddenly seemed all too tight.
He didn’t have time to wonder if Spock had noticed it before he was rolled over once more, Spock laying himself heavily on Jim. His sheath brushed over Jim’s already semi-erect cock, wrenching a nearly silent gasp from Jim as he struggled. His sheath was so hot, he could feel it through their two pairs of pants. Jim resisted the urge to roll his hips, grinding against Spock’s soft, tantalizing sheath. He gulped and continued trying to dislodge Spock, feeling the first beads of sweat rolling down his overheated neck.
Spock decided to let him roll them over again, extending their match so Jim could work up more sweat.
“Wait,” Jim panted, sitting up. He tried to open those damn buttons on his shirt, popping one open before Spock’s expert hands assisted him. Spock followed suit and opened his own shirt, the two tossing them aside and coming back together, skin on skin.
They rolled around a few more minutes, Jim growing sweatier and sweatier, dragging his wet skin along Spock’s in an attempt to smear his scent on him. Spock shivered once, and Jim apologized to his cold-sensitive friend for the chill of the room. At one point Jim had caught Spock by the neck under his arm. Spock struggled for a moment, his face pressed against Jim's armpit, until he was interrupted by a full-body shudder. Jim felt bad enough to release Spock from his hold so they could get into a better position to use his Human body heat.
Finally, when Jim was too tired to go on, he collapsed into a hot, sticky, heaving pile on top of Spock. Spock sniffed the air quietly and gently pushed Jim off of him, Jim dripping a final bead of sweat onto Spock's flushed skin.
“If you are amenable, I would mark you now,” Spock said, his voice deeper than Jim was used to. “Once I have finished, we may ask the Sephins if we’ve met their requirements.”
Jim tensed angrily. He’d forgotten about those lanky, blue bastards.
“I’m ready when you are, Spock,” Jim answered breathlessly. Spock nodded, his eyes nearly black with his pupils so dilated. Interesting.
Spock flipped them over so he straddled Jim again and took Jim’s hands. He brought them to his neck, making them rub the scent glands behind his ears and on the back of his neck. Jim kept it up while Spock dropped his hands to rest on Jim’s chest, suddenly settling more heavily on his hips. He slowly rubbed his sheath over Jim’s now more-than-semi-erect cock and huffed softly. Jim chose not to mention Spock’s previous statement of non-invasive procedures.
Spock lowered himself and nuzzled his face into Jim’s neck, dragging his sandpapery tongue over his hot skin. He plastered his chest and stomach tight to Jim’s body, squirming against him in a way that must’ve been the most efficient technique for spreading scents. He muttered something in Vulcan and spread his legs further, increasing the pressure between his sheath and Jim’s cock. He reached down to palm his own sheath before setting the same hand on Jim’s chest, rubbing his skin. Jim swore Spock moaned quietly once before sitting up and dismounting him.
“I believe that should be sufficient, Captain,” Spock whispered, collecting himself. Ah, right.
Jim cleared his throat awkwardly and stood up. They caught the guards’ attention, who called over the elders. The four elders arrived, still glaring at the two of them.
The purple wall faded and the tallest took another loud sniff. He seemed to be considering it for a moment, but then moved closer to Spock. A few more loud sniffs from close up had his lip curling into a snarl.
“You are not paired!” He yelled, shoving Spock to the ground and getting out of the cell. Jim’s attempt to grab him was thwarted by the purple wall reappearing, which he collided with painfully. “Do not mock us, Starfleet! You have one more chance to pair properly before we are forced to take much less diplomatic measures.”
The elders left again, while Jim made some very impolite comments and slammed his shoulder into the purple wall. Jim backed up for an unwise charge into the wall but was stopped by Spock grabbing his arms.
“Captain, injuring yourself will not solve anything,” Spock hissed, placing himself protectively between Jim and the wall. Jim looked like he was going to keep trying for a moment. “I have another solution, although it is much less professional…”
“What? You already said if I can’t mark you we’re fucked!”
“You said that, Jim, and I only partially agreed with you.”
Jim stared at Spock, waiting for him to get to the point.
“Jim, Human sweat glands are clearly not effective enough to get us out of our predicament, however you are not unable to mark me. Humans possess other bodily fluids that carry much heavier concentrations of their scents. Particularly, semen or urine.”
Jim gaped at him.
“Spock- I can’t just… Are you actually suggesting I-” Jim sputtered uselessly.
“As neither action would be life threatening- or even dangerous in any degree- while we are unsure of what our captors will do, I believe our most logical option would be to have you mark me in one of those ways.”
“The most logical thing to do is pee on you, seriously?”
“I admit I would prefer if you would ejaculate on me, but yes.”
Jim hesitated, trying not to think of how hot it would be in any other situation to cum on Spock. To have Spock asking him to cum on him. While Jim hesitated, Spock knelt in front of him, looking up expectantly like it was just business as usual. Jim swallowed thickly.
“We’re really… Wow, okay,” Jim mumbled in disbelief, fumbling with his pants. Thankfully they weren’t as complicated as his shirt, so he was able to open them himself and drop them before Spock could get involved. He was thankful his semi had calmed a little, so he didn’t appear too eager to defile his first officer. He took his cock in hand and gave it a few awkward strokes, not sure if he should avoid eye-contact or not. “I- um- Do you want me to cum on your… face..?”
“It is likely our captors would prefer if I carried your scent on as much of my person as possible, therefore I suggest you aim for multiple areas, such as my face, neck, and chest, and perhaps my back and posterior as well, if you are able to produce enough semen.”
Jim stared at him, wide-eyed.
“On your ass?”
“That is one of the locations I had mentioned, yes,” Spock raised that damn eyebrow again, as if to say keep up.
Jim tightened his grip, an unintended habit to make himself last longer. He was fully hard now, evidently much more interested than he’d been trying to show. Spock noticed the change in grip, glancing at Jim’s cock.
“If you are experiencing difficulty reaching orgasm-”
“Fuck- I’m not- I just…”
“If you would allow me to-”
“Spock, I got it. I know you don’t wanna be in this situation. I’ll hurry up and get it over with.”
Spock blinked up at him, doing unfair things with those long eyelashes and dark brown eyes.
“Perhaps if you would allow me to assist you, I could bring you to a more satisfying orgasm.”
Jim choked on his spit and reflexively squeezed his cock again.
“I don’t think- is that necessary? You don’t have to do anything, I can just- y’know…”
“It is quite likely you will produce more semen if you were to enjoy this experience more deeply. It is logical, James.”
Fuck. Fuck, he said James.
Jim’s cock leaked precome at that, drooling for that pretty baritone voice saying his given name. Jim made a pitiful noise in response.
With that, Spock gently removed Jim’s hand from his cock, guiding him to instead set it on the Vulcan’s head, running his fingers through his neat hair to mess it up. Fuck, he wanted to mess it up, to leave Spock looking so well fucked. Jim’s desire was only amplified when Spock took his hard cock into his mouth, resting dangerously on his rough, green tongue.
Spock took him to the base, hollowing his cheeks and making a perfect balance of noises. Jim lost himself in the soft moans and gags and the wet suction surrounding his cock, bringing his free hand to touch Spock’s ear while the other tangled in his dark hair and gripped a fistful for dear life.
Jim squeezed his eyes shut and squeaked a pathetic warning to Spock that he was close.
Spock dragged his mouth off of him with a long suck, swirling his tongue over the head and licking into his slit as he stroked Jim with his hand. Jim’s eyes rolled back as he came, moaning as Spock jerked him through it and painted his own skin with Jim’s release. He managed to get it on his face and chest, allowing it to drip thickly down and cover his neck and stomach. Jim swallowed as he followed a drop down to Spock’s waistband.
“Now, as they have mentioned that this was our last chance to do this right, I believe it would be logical to ensure that I have marked you sufficiently,” Spock reasoned, opening his own pants and pushing them down his thighs. He revealed his dripping sheath, the tip of his lok peeking out. Jim nodded his agreement and shakily got down to his knees.
Instead of standing over him as Jim had done, Spock gently pushed Jim to lie on his back and crawled over him, dragging his wet sheath over Jim’s thigh. Jim remained limply in place, groaning quietly as the soft skin of Spock’s hot sheath rubbed all over his most sensitive areas. He hissed through his teeth when Spock set his sheath on Jim’s spent cock, dribbling slick over the hypersensitive skin of his cock and down his balls. Mercifully, he lifted off before moving along to his next location, straddling Jim’s belly and dragging the slick lips of his sheath up Jim’s body and over his chest.
He paused at Jim’s chest. Jim set his hands on Spock’s thighs, trailing them up until he held his ass, and guided Spock to hover his sheath over his mouth. Jim’s tongue reached for Spock’s skin, slipping into the wet heat effortlessly as Spock sat on his face, thighs trembling beside Jim’s ears. Jim pulled Spock’s hips down, driving his tongue deeper into the sheath and gratefully drinking the sweet fluid it offered. Spock’s slick soaked Jim’s lips and chin, and dripped down his neck.
Spock whined and grabbed a handful of golden hair, grinding his sheath on Jim’s lips and his squirming lok on Jim’s nose. Jim mumbled something into Spock’s sheath, the Vulcan’s thighs tensing as the vibrations ripped a loud moan from him.
“C’n fu… you,” Jim’s offer was muffled. Spock lifted himself off with a whimper. “I can fuck you,” Jim repeated.
Spock turned back to see that Jim was indeed able to fuck him, his cock hard and twitching against his stomach.
Spock moved off of Jim, letting him sit up and guide them into a new position. He lay Spock on his front, spine arched gracefully so Jim would have easy access to his sheath. Jim happily took advantage by slipping two fingers into the wet space. Spock moaned his approval and backed into the sensation, fucking himself on Jim’s fingers.
Jim fingered Spock for a few more moments before Spock grew impatient and declared himself prepared. Jim decided not to complain and quickly lined himself up. He breached Spock slowly, gasping at the wet sound it made. He tried not to look too closely at the mess of slick already dripping off of his cock, for fear of coming too soon.
Spock seemed all too happy to make him come, groaning and rocking back onto Jim’s cock. Jim set his hands on Spock’s hips and slowly worked into a gentle rhythm. He took a glance at the soaked sheath milking his cock like it was built for it, biting his lip and resigning to an early finish. Still, he looked away, glancing at the purple wall once again.
He saw the Sephin guards staring back at him. Though they still had their backs to him, Jim could see their hands moving, stroking themselves while they watched the two in the cell over their shoulders. Jim’s blood boiled at the sight, and he sent them a glare with as much fire as he could muster.
He knew it couldn’t be helped- not if they were gonna get out- so he sighed and leaned over Spock, shielding him from their view to the best of his ability. Spock made a pleased noise and rolled his hips a bit faster, clearly enjoying the heat of Jim’s body spread over his back.
“Spock, can I-” Jim bit back a whine. “Can I come inside you? Is that okay?” God, please say it’s okay…
“For our- ah- purposes, I believe it would- oh, Jim- it would be most logical for you to ejaculate on my skin, specifically- ah, ah- on the previously… mentioned locations…” Spock stuttered through his response, speeding up his hips once again, quickly approaching the hard fuck he seemed to be craving.
“Yeah- yeah but… just a little?” Jim didn’t bother to keep the whine out of his voice, he was begging after all. “Please?”
Spock moaned. “Yes, yes, Jim- please… please ejaculate inside of me.” Jim expected to be turned off by Spock’s overly formal wording, but was pleasantly surprised to find it ripping the orgasm from him instead.
He whimpered, giving Spock a good three more thrusts before pulling out and watching his cum splatter over Spock’s tight ass and his long spine. He took care to come on the little bumps at the base of Spock’s spine, knowing them to be chenesi and feeling a possessive thrill at coating them with his cum. Spock must’ve felt it too, because he followed the action with his own orgasm, spurting on the floor for a moment before Jim remembered what they were doing there.
He captured Spock’s lok in the last of its spasms and gently stroked it, catching his cum in his palm despite the wriggling lok’s playful efforts to squirm out of his grip. He brought his hand to his mouth and loudly slurped it up, grinning as Spock watched him from the floor with unguarded admiration.
They sat for a minute, gathering themselves and processing the new aspect of their relationship. Jim cringed as the afterglow faded, feeling sticky and unclean. He licked his lips and still tasted Spock’s sheath.
“Can we clean off? Somehow? You got a handkerchief or some wet wipes or anything?” Jim fidgeted and tried not to let his sensory hell show too much. Spock gave him a sympathetic look.
“I did not bring any supplies for the intent of cleaning ourselves, and I believe it would be wisest to remain with our scents intact until we have safely returned to the Enterprise.”
Jim nodded and wiped at the tacky fluids drenching his lips and chin.
“However,” Spock continued, and began to lick his own mess off of Jim’s skin, “I shall assist you in cleaning your face, if you wish.” Jim agreed eagerly.
After a quick tongue bath, Jim’s face was relatively clean, and he felt much more presentable. He breathed a sigh of relief and smiled at Spock.
“Wanna we get out of here?”
“That has been our goal from the moment we were captured, Jim.”
Jim rolled his eyes and went to the purple wall, pounding loudly on a spot just behind one of the guards’ heads. It was their own fault for leaning on the wall, and Jim watched with wicked satisfaction as the pervert jumped, rubbing the back of their head with a flustered glare. The other guard laughed at his comrade before calling the elders back over. One of the elders sniffed as she approached, shooting a disgusted look at the two guards, who quickly stared at their own shoes.
The purple wall disappeared once again, and the elders entered the cell. Immediately, their attitudes shifted significantly. They fussed over their “honored guests” like good little diplomats and ushered them back to the room they’d started in.
As they entered the room, Scotty and Uhura perked up, still stuck in their corner, with a few extra bruises implying an escape attempt or two. Jim kept his face neutral as he realized the two could easily smell the cum drying on their bodies, and could perhaps see the remnants of Jim’s cum on Spock’s face, though they thankfully didn’t mention it. After a few friendly conversations with their so gracious hosts, the four of them were excused to their ship to discuss things internally.
Jim and Spock made a beeline to their respective quarters. They went in through their own doors and met in their shared bathroom, choosing to take a water shower together- since it was logical to save resources, of course. As was Spock’s insistence that Jim be the one to lather him up, signified by his unsubtle approach at applying soap, by squirting a long drizzle onto his chest and leaning back against the wall with come-hither eyes. Jim had behaved himself for the most part, only fondling Spock a reasonable amount in the process of cleaning him.
Meanwhile, Scotty and Uhura headed straight to the bridge. With Scotty in the chair, he set a course to anywhere else and ordered warp 6. Fuck Sepel II, fuck the Sephins, fuck the elders. After that little meeting they were no longer eligible to join the federation, and likely wouldn’t be for quite some time. Jim made sure it was official by complaining in great detail in his followup log later that night.
