Captain Kirk was sliding down a slope so steep it was more like falling. He could only protect his face with his forearms and hope for the best as he felt rocks bump and jolt him roughly from side to side.
He and Spock had been seeking shelter from a sudden shower of arrows when he took this unfortunate turn. Jim’s footing hadn’t been great in this cave to begin with, the soles of his boots coated in a slick mud from the marshy terrain of the planet, and the drop in the floor and slippery footing meant he had no resistance to turn back. He just had to ride the wave and pray to whatever deity was listening that the bottom of this slide didn’t end in his death.
After a long and painful few moments, just when Kirk thought this could be his anticlimactic end, he noticed a dim pink glow permeating the darkness of his descent. He took a deep breath as the pink light grew brighter, squeezing his eyes shut he held his breath as he landed-
And bounced. On something beautiful, pillowy and soft. He released his breath in one long sigh of relief, his eyes rolling under their lids as he took a few indulgent breaths with a gaping mouth.
His relief didn't last long before he realised he needed to contact his first officer and check he had managed to escape injury from the primitive weapons. Kirk had lost sight of him long before his slide into this cave and it would be a challenge to find him now.
Kirk tried to get up, but the surface beneath him was so soft it took him a few tries to roll his body so he could get onto his hands and knees. He felt around for his communicator and cursed when he found it was no longer in his pocket. It must have fallen out as he landed. He turned on his knee, trying to get one foot up to stand and balanced with his arms windmilling and his eyes widened at the view.
It was some sort of underground meadow. As far as his eyes could see were giant pink bulbs. He looked down at what he was standing on, and yes, the velvety texture and the puffiness suggested flowers. (He silently hoped it wasn’t some sort of nest, and these weren’t eggs he was disturbing. There’s only so much bad luck one landing party can have.)
He turned and looked up at the hole in the cave wall that he had fallen through, then back down. His comm should be around here somewhere. Kirk hopped from the bulb he was stood on to another and began to scan the ground for it so he could attempt to contact Spock. He lost contact with the Vulcan a while ago and hoped he had found shelter until they could get beamed back to safety.
He spotted his comm nestled in the seam of the bulb to his left and stopped and fell to his knees to reach it. As his fingers touched the petal, he had a brief thought that it felt like velour, before the plant started to open. He flinched back and wobbled, losing his balance. Kirk fell on his ass with his hands catching the worst of his fall. No sooner had his hands touched the plant he landed on, this one also started to open up.
Petals unfurled to reveal a fluffy green centre; Jim tried to move away from this flower but as he turned to step on a neighbouring bulb he was grabbed on the arm. He stared at the culprit, eyes widening as he saw it was a yellow tendril that had emerged from the plant. He reached for it instinctively and attempted to pry it off and another tentacle like appendage came and grabbed his hand. The grip the plant had on him tightened to an uncomfortable degree. He grunted with pain and the tendril loosened.
Kirk frowned at it, wondering if it really changed it's grip based on his verbalised pain when he noticed the sleeve of his uniform tunic was beginning to dissolve.
“Oh, no.” The icy wash of panic sluiced Kirk’s gut as he tried with fresh vigour to remove the tendril. He dug his heels in as he pulled and another tentacle came between his thighs and looped up over his hip whilst another snaked up his shirt.
He was twisting and wrestling with five of these thick yellow vines; they wrestled his limbs apart and were slowly dissolving his clothing.
“Captain!” Spock exclaimed.
“Spock, keep your distance! I don't want you snared, too.” Jim was so relieved to hear his friend, it helped nullify some of his initial panic. He scanned the area with rapid eyes, whilst constantly checking the state of his own natural bondage. He couldn’t see where Spock was, but he sounded close. He felt his uniform beginning to dissolve along his hips and chest where two of the thick yellow ropes were rubbing against him.
“I am already in the grasp of one of the bulbs.” Spock spoke levelly.
“Where?” Kirk found himself scanning again with a deep frown on his face, the vines tangling around him forgotten. “Oh.”
Kirk spotted the top of Spock’s head and tiptoed to see better. His first officer was hidden from view by one of the plush pink petals, but as Kirk craned for a better look he could see a lot more… flesh than usual.
“The plant is dissolving my uniform too, has it penetrated your skin, Spock?” Kirk asked.
“Negative.” Spock responded, and after a moment added. “My entire uniform has been dissolved by the mucus on the stamen.”
Shit thought Kirk as he felt the chill of more and more air against slowly revealing flesh. “Let’s hope it is as harmless to human flesh as it is to yours.” Kirk couldn’t help but wonder if this would be another superior notch in the Vulcan biological belt as he dug his fingers into the meat of the thickest tendril around his ribs; it squeezed harder and he wheezed.
“If you cease resisting, it will relax its grip.” Spock spoke again, and Kirk resisted his instinct to fight against the tight coil of tentacles around his torso. An image of being suffocated by a terran snake came to his mind and he had to close his eyes and take a calming breath. After a few moments of calm breathing the tendrils began to relax, and he tried to approach Spock by crouching down. The vines gripped him once more before he'd made it very far and he grunted, wincing as he was held in a more uncomfortable position, one knee up and twisted to the side and with an elbow on the base of the flower.
“Handy to know,” he choked, taking some slow steady breaths until the tendrils relaxed once more. He made to move again toward Spock but was quickly gripped again, thankfully in a more comfortable position this time, sat as though reclining in a comfortable chair. Now he’d made it to Spock's side he could see the Vulcan looked completely naked beneath the yellow vines.
“Are you injured?” Kirk asked, looking Spock up and down for any sign of his vibrant green blood.
“No, Captain.” Spock turned to look at Kirk and an eyebrow rose. “Are you?”
“No.” Kirk smiled. “Can’t say the same about my uniform.” He looked down and watched as the material slowly dissolved, threads shrinking into thin gossamer cobwebs before floating away.
“A fascinating phenomenon.” Spock commented as he watched the command gold peel up Kirk’s arm. “A curious substance, for what purpose does it only penetrate clothing and not flesh?”
“I’m not complaining.” Kirk smiled, looking up at the cavernous ceiling above them. “It is just a wonder how we will get out of this particularly sticky situation.”
“The longer I have remained stationary, the more freedom I have to move. I suggest we wait until the plant gains a false sense of security about our escape, and then carefully extract ourselves.” Spock demonstrated by lifting one arm out of the enclosed vine gently, the vine lazily reaching back to grab him.
“It does seem to match the energy of its captive. Let’s try that and hope this slime isn’t anything to worry about.” Kirk pursed his lips, keeping his breathing calm and even.
After half an hour, a few thwarted escapes and tightenings, the vines were at last completely loose. It encased Kirk from his waist to thigh in a cocoon. If Kirk moved within them gently, they hardly moved. He began to sweat ten minutes ago, and now felt restless. He tried not to react.
“I am going to try and move out now, Spock. I find myself feeling a little… off.” He glanced to the side to see if Spock was similar but the Vulcan had his eyes closed.
“‘Off’ in what way, Captain?” Spock asked, voice deep.
“A little warm, I feel… itchy and I have the urge to move like I have a restless leg. It’s hard to say. I am trying very hard not to move. Sometimes it’s crazy, I'd rather be running for my life than sitting still like this.”
Spock licked his lips and Kirk felt a familiar and shocking surge in his abdomen at the sight. He frowned. No.
“I believe…” Spock began and Kirk closed his eyes, knowing what his astute science officer was about to say. “The slick that has dissolved our uniform has been seeping into our skin, and it is, in fact, an aphrodisiac.”
Kirk blew out air. “It was only a matter of time.”
“Captain?”
“This is the stuff of legends.” Kirk scoffed. “To explore new worlds, infinite diversity, infinite combinations. Didn’t you hear the myths in the academy?” He asked, slowly resigning himself to the fate that was to befall them which synced with the heat rising in him. He licked his lips and moved his hips, which were steadfastly wrapped in the plant now he had inadvertently been gyrating in them, and that pressure was making his arousal spike in his gut.
“I did not participate in idle gossip,” Spock replied tersely, his eyes glancing to the side to watch as Kirk moved under the plant. “Although… I had a story told to me, first hand, by a xenobotanist on Starbase 11 whilst I attended a science conference.”
“You what?” Kirk turned his head to stare incredulously at Spock. A confirmation of an urban legend from his astute first officer himself.
“He stated… that it was simultaneously the most intense and… pleasurable time of his life. He was restricted from cultivating the plant, for what reason, he could not say.” Spock’s pauses between his speech were telling.
“That’s wonderful,” Kirk declared sarcastically. He wasn’t sure why but a small part of him felt jealous of the xenobotanist. He was out there having euphoric life changing sex and Kirk was stuck here, trying not to sexualise his very sex-averse first officer. Trying not to sully his most precious friendship with a man who confessed to him that their friendship brought shame as it was. That was a long time ago, Spock has come a long way since then. Kirk licked his lips. He felt a sudden roil of courage, and before he realised what he was doing he asked, “What else did he say?”
“He said… that his nerve endings were heightened exponentially.” Spock cleared his throat, and Kirk couldn't help but stare at the Vulcan’s throat as it bobbed in a swallow. And to Kirk's surprise he added, “-that parts of his body were sensitive that weren't before. He described… he described that even his arms and hands being touched was… erotic.”
Kirk was astounded. Was this Spock's version of dirty talk? No. It couldn't possibly be. It was the potent aphrodisiac talking. His unusually verbose first officer tended to shy away from vocal expressions when in awkward situations and was just trying to offer… a distraction.
“So imagine if a body part that isn't normally sexual became sexual, what would an already erogenous zone of the body feel like to be touched under the influence?” Kirk squeezed his eyes shut for a moment as he realised he had spoken aloud his first thought. Where had the audacity come from for him to start this inappropriate conversation? He noticed precome dripping freely from his cock. That was where the audacity had come from, and he was about to ask for Spock's forgiveness when the Vulcan spoke again.
“The hands, for Vulcans, are already erogenous zones, Jim.”
“They are?” Kirk frowned, mouth agape for a moment before he closed it. “Well that makes sense, actually, with the telepathy-” Kirk gestured to his own face with his fingers near the psipoints and watched as Spock's pupils dilated and the Vulcan lurched towards him only to be stopped by the vines tightening on him.
Kirk was panting as Spock was face to face with him now. His first officer was held tightly by the vines of the flower, but Kirk could see the muscles straining beneath. Spock was vibrating with tension and he wanted to help him. Kirk played the moment over again in his mind and wondered what Spock had been about to do to him. If those vines hadn't tightened, would Spock have closed that gap?
“I apologise, Captain. It appears watching your hand move to your face was… it was like watching you… commit onanism.”
Kirk's eyes widened. “I'm sorry, Spock. This isn't an ideal situation.” He groaned at the ache in his cock. He hadn't been this aroused in his life and it was beginning to become urgent. Not just an itch for something he really wanted, but a need. He felt it like it was a starvation.
“Perhaps onanism could help?” Spock had relaxed enough that the vines loosened, and with that extra freedom the Vulcan moved to his hands and knees, coming up to Kirk.
“Consent is difficult in our current situation.” Kirk closed his eyes so he couldn't see the view of Spock crawling into his lap. It was torturous. The slink of those fluid hips, the hidden strength in those taut muscles, it was a wet dream he didn't realise he had had before. Was Spock always this sexual? He couldn't tell if the plant was removing his professional goggles and Spock had always been this way, or whether the Vulcan was strongly under the influence.
“It is, but I believe we may be able to classify our current situation as a medical emergency and we would be assisting one another. I burn.”
“Wait. This is triggering pon farr?”
“I do not know. Jim, I have never felt this way before. It is like pon farr in many ways, but it is not the same.”
“I think I understand. Perhaps it is the need to… ejaculate. If we satiate this need, maybe we can leave.”
Spock looked down at himself and back up at Kirk. He looked almost lost and Kirk couldn't stop himself from saying breathlessly, “Touch yourself, Spock.”
The Vulcan groaned at the command, a hand snaking down his body and ducking under the vines which had loosened considerably. Kirk copied the movement, hand slipping under his own vines to wrap his hand around his throbbing prick.
Kirk moaned long and deep at the first gentle stroke, careful not to upset the plants and make them tighten again. His hips jolted at the sensation of his thumb brushing over the head of his cock and he whined as he was held fast again by the tentacles. “This is impossible,” he groaned, and opened his eyes again to watch Spock. His elbow was the only part of him revealing he was touching himself. Kirk could hear Spock's breathing changing, and if that wasn't the sexiest thing he had ever heard. Spock had never been breathless as long as Kirk had known him, and he could practically feel his stuttering breaths he was so close.
Kirk was still watching as Spock stopped and put his hands behind himself with that same grace that stopped Spock’s vines tightening. It took Kirk a minute before he realised Spock was fingering himself now. “You can come like that? Wait, doesn't that hurt?” Kirk asked, astonished.
“I used my body's own lubrication, and Vulcan muscle control. I am uncertain if I can achieve orgasm this way, but I have a compulsion to try.” Spock held his breath as he moved very carefully. Kirk was agog at the idea that Vulcan’s could use muscle control during sex, he watched every tiny movement, imagining what it looked like and what that could feel like. Spock's fingers were so long and elegant.
“Jim! Jim- oh-” Spock cried as he thrust forward and his moan was cut off into a huff by the vines.
“My…my hands feel... Much more sensitive.”
“Fuck, Spock, watching you like that is driving me crazy.” Kirk groaned, expression pained.
“I can share our… physical sensations, to assist our end goal.”
Kirk's heart leapt in excitement.
“Yes! Please, do it.” He turned his face to Spock, who had an expression of awe as he reached forwards with his free hand and, as soon as his fingers touched Kirk’s face, initiated a light meld.
The next thirty seconds stretched into an eternity before them as they both came simultaneously. Spock felt Kirk's expert grip on his own cock, twisting on the head as he liked. Kirk felt Spock's long fingers pumping inside, how the tight pressure against sensitive fingers tingled wonderfully. Mutual masturbation transformed into reciprocity.
As they were panting and recovering from their orgasms, Kirk realised they were free. The plants had released them, the tentacles lay haphazardly strewn across the bulbs. Kirk could see their spend, milky white, dripping from them.
Spock stood and offered Kirk a hand up.
Kirk cleared his throat as he took it.
“I saw my communicator down here, I'll just get that and we can attempt to contact the Enterprise.”
He turned and stepped to the adjacent bulb, then the next to bend down and grab his communicator caught low on a large flat purple leaf.
“Captain!” Kirk turned to the tone of alarm in Spock's voice and caught his first officer attempting to push him out of the way of a vine coming to wrap around him. Unfortunately, the urgency of Spock's actions caused the vines to react lightning quick, and both of them were wrapped tightly together. Chest to chest, thigh to thigh. This one plant had the two of them in a tight grip, the slick on the tendrils no doubt infusing them with more sex hormones but also acting as a lubricant. Kirk let out a broken moan and let his head fall onto Spock’s shoulder.

Spock moved his knight up a level and glanced at Kirk. It had been a few days since the incident, which had turned out to be pretty harmless, if a bit embarrassing when it came to writing the report. Though Kirk's gut instinct was telling him to bring it up with Spock now.
“Spock.” He smiled, moving his own knight in retaliation.
“Yes, Captain?”
“How did you find our experience with those pink bulbs?”
“You read my report, Sir.”
“No, no, no. I want to know unofficially. Your… personal opinion.” Kirk looked up at Spock through his eyelashes.
“I found the experience… intriguing. To have my inhibitions removed and the intensity of sensations increased… it was not unpleasant.” Spock's eyebrow rose and Kirk could tell it was a lot for Spock to confess. His first officer was always so honest with him.
“Was it solely the effect of the plant you found pleasant?”
Spock shifted, sitting back and fortifying himself. The silence that followed was thick, but Kirk had infinite patience for his first officer.
“It is that I experienced it with you that I found pleasant, Jim.”
The smile that split Kirk's face was perfectly charming. The face that many fell in love with across the galaxy, but there was a look of knowing that was so tailored to Spock that the Vulcan began to blush.
“Well, that's a relief, because I find myself unable to forget those feelings.” Kirk stood and circled their table. He placed his hand on Spock's and leaned forward. With a little concentration, Kirk thought about his affection for Spock, and swiftly followed that affection with the slick warm feeling of their bodies writhing against one another as those tentacles clutched them tighter. Kirk specifically honed in on the feeling of his cock dragging across Spock’s hole, the thrill it caused him and the unexpected but welcome feeling of his lower abdomen swarming with affection.
Kirk heard a small intake of breath from Spock before the Vulcan stood and crowded into him.
“I believe I would like to experience the second instance of our entrapment to the plants again, Captain.”
“Of course.” Kirk hummed softly, the events unfolding exactly as he had hoped. “Anything for you.”
