Spock twirled the object in his hand, studying its bright pink colouring with a raised eyebrow.
“What am I to do with this?” he asked his bondmate, who watched with barely-restrained eagerness from the bed.
“It’s a vibrator,” Jim offered helpfully. “I was hoping we could use it to try something new in bed.”
“You intend to use this for sexual purposes?” Spock held it up to the light.
“Well, I don’t think they’re used for any other purposes.”
Spock handed it back to Jim, wordlessly giving him the chance to demonstrate its use. Jim pressed a button on the underside of the device, springing it into action with a low buzz.
“I got this one because it has a couple of different modes,” Jim explained, switching it to a faster vibration, and then to a pulsating pattern. “Thought it would be nice to change things up.”
Spock nodded and sat at the edge of the bed.
Jim got onto his knees and gently pushed his husband down onto the sheets, straddling his still-clothed thighs. The human looked down at his Vulcan, a twinkle in his hazel eyes. His fingers stretched out across Spock’s chest, feeling him through his clothes.
“Can I take your shirt off?” Jim asked.
Spock nodded and sat up a little so his bondmate could pull the clothing over him. Underneath the blue uniform shirt was the regulation black undershirt, which Jim did not remove just yet. Spock lay back down on the sheets, waiting for his next move. Surely enough, Jim couldn’t resist thumbing at Spock’s nipples through the material. His lips quirked up in delight as they hardened under his touch.
“You know, sometimes I forget how lucky I am that your nipples are so responsive,” the captain mused. Spock kept his mouth shut, opting to breathe out slowly and deeply through his nose. He knew that if he went to reply, his voice would likely lack the steadiness it usually held.
Jim kept teasing them through his shirt, squeezing and pulling, savouring every tiny hitch in the other man’s breath. His own nipples were not as sensitive as Spock’s, which was why he found it utterly fascinating to watch his husband’s body react to the slightest of stimuli. He squeezed a little harder on one pebbled nipple revelling in the twitch of Spock’s hips under him.
“Mind if I try the vibrator on them?” he asked, picking up the device from the sheets. Spock nodded, giving him permission.
Jim grinned and switched it on to its lowest setting, the soft buzz drawing Spock’s attention. He brought it down to one hardened peak and let it make contact through the shirt. Spock’s reaction was minuscule—probably unnoticeable to anyone except his bondmate—but nonetheless, he reacted. His jaw clenched and he sucked in some air through his nose.
“Aww, babe, why won’t you talk to me?” Jim feigned sadness. “Tell me how it feels on you?”
Spock’s lips pressed incrementally tighter together. This was a trap and he knew it. Jim was a mastermind of manipulating him into opening his mouth—and once he did that, it was too late to shut him up. Spock was acutely aware that his bondmate got off on the noises he made in bed, but that did not make it any less embarrassing for the Vulcan who had spent his whole life trying to regulate his emotions.
Realising Spock was going to be difficult tonight, Jim employed his so-far foolproof strategy. He cupped his husband’s face letting his thumb brush over his lips. Then, with very little warning, he pushed the tip of his index finger against the seam, parting them and meeting Spock’s teeth.
The Vulcan gasped softly, jaw unclenched just enough that Jim’s finger slipped inside, meeting his tongue. Spock couldn’t help the whine that left him. There was simply something about having Jim’s fingers in his mouth that made him so wet. And Jim knew.
“There you go, sweetheart. That’s what you wanted, hmm?” Jim moved the vibrator to the other nipple, catching Spock off guard.
Spock’s hips bucked up, seeking friction with Jim, but the captain was quick to raise himself to his knees, denying the man under him.
“I bet you really want me to use this on your sheath,” he mused. Spock’s lips closed around Jim’s finger and he licked and sucked and nodded. “Guess I could give you half of what you want.”
Spock shut his eyes and focused on the pleasure of the warm finger in his mouth, unable to stop the soft moans leaving him. He could feel his sheath’s most efficient self-lubrication mechanism working overtime, soaking into his underwear and eventually his pants. His lips parted in a loud gasp, back arching as Jim pressed the vibrator to his sheath. He could not help but buck into Jim’s hand.
The captain removed his wet finger from his husband’s mouth and traced it down his neck. Then, hearing his moans quieten as he got used to the sensation, Jim cruelly drove the vibrator harder against the damp fabric of Spock’s uniform pants, thumb pressing a small button on the side of the device to increase the intensity.
The Vulcan whimpered and nodded helplessly, rolling his hips against the device. Jim kept his hand steady, providing just enough stimulation to keep Spock on edge, but not enough to push him over. He leaned down and pressed his lips to Spock’s neck, right at his pulse point. Kissing his way up to his ear, he whispered, “Tell me what you want.”
Spock swallowed, doing his best to regulate his breathing. Pleasure was a thing of the mind. He could control himself. He stayed silent, slowly getting used to the buzz against the fabric of his pants.
Tired of waiting, Jim shut the vibrator off with a click. Spock gasped, suddenly raw and empty without the touch. His sheath throbbed, begging for more.
“Last chance,” Jim teased in his sing-song voice. “Tell me what you want or I’m putting this away.”
“Remove my clothing,” Spock whispered. He could not trust himself to say much more because there was a chance he would not stop.
“Sure, but where are your manners?” Jim cooed, brushing his thumb over his partner’s bottom lip.
Spock’s eyes fluttered shut, but he managed to murmur a pleas.
“Good boy.”
With that, Jim’s weight shifted off him and Spock cracked open his eyes to see what was happening. His bondmate was at the foot of the bed, vibrator discarded on the sheets beside him. Tenderly, Jim lifted one of Spock’s feet, cupping the heel, and peeled off his sock.
“Is this what you wanted?” he asked, doing the same to the other foot.
“Jim,” Spock’s voice came out breathless. “I—”
“You what?” The captain massaged the soles of his husband’s feet with the circular motion of his thumbs.
“I req—” Spock clamped his mouth shut just in time to prevent a sigh. With a falsely casual shrug, Jim let his foot fall to the bed and took a step back. Spock propped himself up on his elbows, brown eyes wide with need. “I require you to continue.”
“Continue what? Jim ran his fingers over Spock’s toes. “Massaging your feet?”
“No,” the Vulcan hesitated. He glanced down at the unmistakable wet spot on his pants and then back up at his infuriating bondmate.
“Then what?”
“Continue using the vibrator.”
Jim broke out into his grin again, hazel eyes sparkling and he practically pounced onto Spock. Warm, human hands pressed on his chest, pushing him to lie back down. Pulling away for a breath, Jim nuzzled his nose against him. “I like it when you use your words.”
Spock’s stomach did a little flip somewhere inside, sheath throbbing again as a reminder that it was in dire need of attention.
“My sheath,” he rasped out. “Please.”
Jim’s hand travelled down to the wet spot, and the human hummed in appraisal. Without much of a warning, he squeezed the sheath through the pants, causing Spock to yelp. “That’s quite a mess you’ve made, Mr Spock.”
“Jim…” came the soft groan.
“Alright, alright,” the captain swiped away the black bangs and kissed his forehead. “Let’s get your pants off.”
Moments later, Jim was kneeling between his husband’s thighs, vibrator coated in lube, looking at his swollen sheath. He ran a finger up the slit, spreading the wetness onto the hairs that covered the skin. The Vulcan’s thighs trembled in anticipation.
“Spread your legs for me,” Jim ordered, moving his hand up to his husband’s stomach under his shirt.
Spock obeyed, drawing his knees apart to reveal the whole of his sheath. He sighed into the warmth of Jim’s hand on his stomach and tensed a little when the cool rubbery toy made contact with his folds. Jim hadn’t turned on the vibrations yet, giving him a chance to get used to the device sliding up and down the slit.
“Do you want me to turn it on?” Jim asked. Spock nodded, but Jim didn’t oblige. Instead, the cruel man waited for him to speak.
“Yes.”
There was a soft click, and then a light buzz that hit Spock right in his core. He could hear the tiny whines and whimpers leaving him, but he was powerless to stop them. Worse—his fra’ls were forcing their way out to explore whatever this new sensation was.
Spock didn’t even realise they had wrapped around the vibrator until they pulled it closer, seeking more friction.
“Oh baby, you’re so excited,” Jim chuckled.
He let go of the toy and crawled up on top of Spock, leaving his fra’ls to play around. The Vulcan could see the tent in his bondmate’s pants, which only served to make him wetter.
“Tell me how it feels,” Jim asked between kisses at Spock’s ears.
“It—my—the vibrator is stim—stimulating my pelvic anterior—nerve cluster—” Spock choked out between other more obscene sounds.
“Oh? Will you show me where that is?”
Jim knew exactly where Spock’s pelvic anterior nerve cluster was located. In fact, it was the precise place he enjoyed teasing during oral sex.
“You—you are aware—”
“Show me anyway. I want to see you touch yourself.” The was an edge to Jim’s voice that mirrored the commands he gave on the bridge, and suddenly Spock’s fingers moved of their own accord down to his sheath.
He parted his folds and guided the vibrator to press exactly against the point at the top where the folds joined into one. He cried out, hips jerking up, clearly miscalculating just how the nerve cluster would respond to direct stimulation. Quickly, he pulled the vibrator away from that particular spot, handing it back to his fra’ls. He lay panting under Jim.
“Fuck, that was hot.”
Spock looked up at him, lips parted as he caught his breath. “Jim…”
“Yeah?”
“Will you… please…” his request morphed into a whimper as the vibrator hit that sensitive spot again.
Jim returned to where he had previously been between his legs, gently prying the slick device out of the fra’ls’ grasp. Once he had it in hand again, he increased the vibration speed and returned it to the sheath. Spock clamped his knees around Jim, holding him in place, writhing under the influx of new stimulation.
“My lok—” he gasped.
Just then, Jim noticed the tip of Spock’s wet green member emerging from between the folds of his sheath. Directing the buzzing vibrator at it, he revelled in the delicious cry his husband let out. His pretty back arched off the bed, and his fingers tangled themselves in the sheets. Jim, in devious move, clicked the button one more time, increasing the frequency of the vibrations. And to his delight, Spock threw an arm across his face, biting down into his own bicep to stifle his cry.
This simply would not do. Jim needed to hear Spock let loose—to see his perfectly stoic husband scream in pleasure.
He pulled the vibrator away from the now fully erect lok, leaving Spock shaking and bucking his hips in hopes of finding stimulation.
“Jim!” whimpered the Vulcan. “Please, no!”
“I’m not done with you yet.”
Keeping as still as possible, Spock waited for whatever his bondmate had lined up for him next. He watched in silence as the captain stood, went over to the bedside table for more lube, and returned with the whole bottle.
“On your stomach,” he ordered.
Spock obeyed, rolling over, though his legs were still weak. He could feel Jim’s warm fingers pressing on his chenesi, but just as he was about to press up against them, they abandoned him. They returned a moment later, further down, pulling his cheeks apart to reveal his hole. Jim leaned down, breathing in Spock’s scent, taking in the sweat of a day’s work, mixed with the natural smell that was just Spock.
Ready for his bondmate’s fingers, Spock shifted his hips. But to his surprise, rather than Jim’s lubed fingers, he felt his tongue.
Jim began by licking the stretch of skin from the base of Spock’s sheath right up to his hole. His tongue brushed over the coarse hair, lining the area with his spit. His breath tickled Spock’s hole, but he wasn’t going to give his husband everything just yet. Instead, he pulled back, reapplied a dose of lube to the vibrator and pressed it to that same spot. Beginning at the lowest level, he felt the Vulcan squirm and attempt to rub himself against the device. But that was all he would get. The captain turned it off again and left Spock wanting.
“No!” Spock whined. “Jim—why?”
“Just wanted to tease you,” he replied, leaning back in.
This time, he allowed the tip of his tongue to circle Spock’s hole, keeping his touch light enough to infuriate the man under him. Flicking it once against the centre, he returned to the space just after the sheath.
“Jim, please—” cried Spock. “Please, I need you.”
“Need me to what?”
“Fuck—”
Both men were silent for a second, neither fully able to comprehend that Spock just swore. He knew the word. He’d heard Jim use it countless times. But he had never*, never* said it himself. Jim waited, heart hammering, cock straining against his own pants, praying his husband would say it again.
“Fuck me,” Spock finally whispered.
Jim’s cock pulsed with the desperate need to bury itself to the hilt inside this man. He wanted to shove his tongue down Spock’s throat and fuck him so hard he couldn’t say anything but fuck.
Concerned by Jim’s silence, Spock turned his head, laying on his cheek so he could get a good look at the human. He saw the darkness of desire in his hazel eyes and opened his mouth to remind him he could fulfil his desires at any time, but Jim beat him to it.
Pulling Spock’s head up by the hair, Jim savoured the Vulcan’s hiss of pain and pleasure. He crashed his lips onto Spock’s letting his tongue explore his mouth. Spock moaned against Jim’s lips, taken off guard by this sudden eagerness. He thought Jim was going to torture him with denial tonight.
“Fuck, Spock,” Jim pulled back, chest heaving. “You swore.”
“Yes.”
“I’m gonna fuck you so hard you do it again.”
Despite the dishevelled state of his hair, and the fact that his ass was open and begging for Jim’s cock, the Vulcan still had enough composure to raise an eyebrow at the challenge. Jim didn’t wait a second longer. He went back to where he was, spreading his husband’s ass and burying his tongue inside.
The hole was so tight and warm and Jim just managed to squeeze the tip of his tongue inside. He swirled it around, feeling Spock relax around the intrusion. Finally, when he had enough space, he plunged the rest of it inside. Somewhere above, Spock gasped.
“J-Jim! You are—*oh—*you are so warm,” Spock babbled, his words half-muffled by the pillow. “Your tongue—”
The captain returned his fingers to press on Spock’s chenesi, rubbing circles into his lower back, on either side of his spine. At the same time, he thrust his tongue in and out of his hole, fucking him as hard as he could without his cock.
Spock raised his ass in an attempt to chase Jim’s retreating tongue, but Jim pushed him back down, pulling his tongue out to lick broad strokes across his entrance.
“Oh Jim—I must—I must have you—have your cock—” the Vulcan shuddered and pleaded.
Jim said nothing, but he retreated for a moment. Spock heard the sound of Jim’s zipper and then the lid of the lube bottle opening and closing. What followed was the slick noises of Jim preparing himself… or something else.
“Up,” Jim instructed, slapping Spock’s ass. Instantly, it was raised a few inches above the mattress—just enough room for Jim to turn the vibrator back on and slide it just under his sheath.
As Spock lowered himself, he made a small whimper. His lok was perfectly aligned with the toy, his fra’ls pulling it into place. However, Jim was cruel. He’d only turned it onto it’s lowest setting—nowhere near enough to satisfy him now that he was beyond aroused.
Before he could articulate this, every thought fled from his mind. The tip of Jim’s cock was lined up against his hole, and—oh—he was inside. Jim slid in fast and hard, his hand gripping the Vulcan’s bony hip with a strength that could easily bruise a human. As soon as he was completely inside, he pulled out, almost all the way, only to slam back into him. The motion jolted Spock’s lok against the vibrator.
“Jim—ah—oh—”
“Come on, Spock, use your words,” the captain grunted, pumping harder.
“I—I cannot—” Spock whimpered, struggling to alternate between meeting Jim’s thrusts and humping the bed for better friction with the vibrator. “Jim—please—”
“Fuck, Spock,” his bondmate panted. “You beg like a fucking whore.”
Spock’s lok throbbed at this word. It was dirty. He knew that. A whore was a promiscuous, wanton person who gave themselves up for sex.
Yes… Spock wanted to be Jim’s whore.
“Please, Jim…” he cried between the force of Jim’s thrusts. “Make me your whore…”
Somehow, this made the human fuck him faster. A moment later, he spoke, voice rough with want. “You wanna be my whore? Then beg.”
Jim landed another slap on Spock’s ass. The Vulcan yelped and squeezed his eyes shut at the delicious sting of pain. “Strike me, Jim. Please?”
“You can beg better than that!”
“I—mm—I require—”
“You require nothing!” Jim leaned down to hiss into his ear. While he was there, he nibbled at the pointed tip, making Spock grind harder against the useless vibrator buzzing beneath him. “You will beg and take whatever I give you.”
“Y-yes,” Spock whimpered. “Please, please Jim—will you increase the—the vibrations?”
Jim continued fucking his ass, but he reached down, squeezing his fingers below the sheath, disturbing the fra’ls. He found the button to increase the vibration speed, but as his hand was retreating, the fra’ls managed to grab it. Wrapping themselves around his fingers, they began the work of establishing the psychic connection required for Spock’s climax.
“Th-thank you—” Spock mumbled incoherently. “I—ah—”
“You’re gonna cum?” Jim asked.
The Vulcan opened his mouth to speak, but couldn’t manage any words. He simply nodded and tried to focus on the fullness of his bondmate’s cock inside him.
With his free hand, Jim slapped his ass again, harder. A patch of green showed up on his skin and he hissed. Jim only thrust into him faster, pushing him down onto the mattress so his lok was unable to escape from the vibrations.
“Ngh… Jim…”
The captain threaded his fingers back through the sleek strands of Spock’s hair, tugging just enough to make the Vulcan groan incoherently. Jim could feel the beginnings of the psychic connection, Spock’s desperate need seeping into his mind. Reaching out through their bond, the human gave him the permission he thought he needed.
“Cum for me,” Jim ordered out loud. He slowed his thrusting at the start of Spock’s orgasm.
Beneath him, his husband spasmed and cried and murmured his name. Though Jim couldn’t see his lok pulse as cum spurted out, he could feel the clenching of Spock’s internal muscles, milking out every last drop from inside. They squeezed Jim’s cock, massaging it closer and closer to his own orgasm.
As these contractions slowed to a stop, Jim gradually increased his pace again, feeling Spock go slack under him. The boneless Vulcan could do nothing more than whimper half-hearted protests about how sensitive he was, occasionally yelping or gasping when the still-going vibrator touched the tip of his lok. Worse, Jim was still fucking him, now pounding into his hole, watching it clench and unclench without control.
“P-please Jim…” he sobbed, tears glistening in his eyes. “I—I cannot—”
“I’m almost there. You can hold on a little longer, can’t you?”
Spock squeezed his eyes shut and nodded, quickly turning his face into the pillow to muffle his overstimulated cries.
Jim was so close. He could feel the heaviness in his own balls, desperate to unload themselves deep inside his husband. Snapping his hips harder, he plunged into Spock one last time before collapsing over him, letting his cock pump out his seed. He bit down on the Vulcan’s shoulder to stifle his own moan, and the Vulcan twitched beneath him, still a slave to the vibrator.
Only once Jim too had been milked dry did he dare remove his cock. His cum had already trickled down from Spock’s hole to the base of his sheath, coating the hair with white. Reaching under him, Jim finally removed the vibrator.
“Oh—Jim!” Spock grinded against the bed, involuntarily seeking the missing friction. “Th-thank you…”
“Don’t thank me just yet,” the captain smiled. He turned the vibrator onto its third and highest level and directed it straight at that spot between Spock’s sheath and hole.
To say Spock screamed would have been an understatement. The sound he made could only be described as animalistic as his body convulsed. No matter how hard he tried, no intelligible words left his mouth. All he could do was make pathetic sounds in an attempt to convince Jim to leave him to recover.
Suddenly, the vibrator was gone, replaced by Jim’s fingers. They massaged his cum into Spock’s skin, rubbing it against his tender hole and using it as lubricant to guide a finger inside.
“You’re still so open, baby,” Jim commented.
Spock’s greedy hole was busy trying to swallow Jim’s finger, pulsing around it and drawing it in. Jim obliged it, sliding in and out at a slow pace, fucking his own cum into his husband. Meanwhile, Spock shook and cried under him, his fra’ls exhausted and returning to his sheath. In the last vestiges of their psychic connection, he begged Jim to let him rest.
“Can I clean you up?” Jim asked out loud.
Spock nodded wordlessly, but rather than feeling Jim get off the bed to search for a towel, he felt him pulling apart his cheeks again. Warm breath hit him just before Jim’s tongue returned to his hole. This time the captain was gentle. With broad strokes, he lapped up his own cum and swallowed it down, careful not to overstimulate him again. Spock’s thighs still shook with the remnants of his pleasure, but he sighed softly and sunk into the pillows, letting his bondmate care for him.
“Let’s head to the shower,” Jim said. He pressed a kiss to the part of Spock’s ass he’d previously slapped.
Spock groaned, but he didn’t get up. His limbs were heavy and he no longer had the energy required to get up.
Seeming to sense this, Jim cupped the same spot of Spock’s ass. “I’ll go warm up the water and then I’ll come get you.”
The Vulcan hummed in agreement and let his eyes flutter closed. He could feel the urge to sleep pulling him in, but he promised himself he would get up as soon as Jim returned…
“Spock?” A hand shook his shoulder, trying to wake him. “Baby? I have the shower running.”
Spock tried to speak, only to ask for a few more minutes to rest. But no words came out.
“Sweetheart, come. Just a quick shower and we can go straight to sleep.” Jim gently pulled his husband’s arm, finally watching his eyes open. “You were so good for me. Please, let me take care of you?”
The Vulcan peeled himself off the bed, suddenly aware of the sticky patch of cum splattered across his stomach and the sheets below. He looked down, then around, searching for something to wipe it off with. Jim handed him a warm, damp towel, already anticipating what he would need.
When he was done wiping away the mess, Jim helped him up, guiding him into the bathroom where the water was running just below Spock’s preferred temperature—at a spot that Jim’s human skin could also handle. Spock stepped inside first, and once the shower door was closed, he turned and sagged into Jim’s arms. The captain held him close, chest to chest, gentle fingers stroking his back.
“You okay?” Jim asked from under the shower spray. He felt Spock nod against the side of his neck and decided to let him remain for a few minutes.
Eventually, Jim lathered up a washcloth and ran it over his husband’s back and arms. He continued onto his face and front, making sure any remnants of their earlier activities was cleaned away. Jim bent down to soap up Spock’s lower half, but when he brushed over the skin of the his sheath, the Vulcan’s knees buckled. He leaned forward onto Jim, steadying himself against his shoulders.
“Sorry,” the captain said from below, moving on diligently to Spock’s legs.
Jim finished up with his husband’s feet while Spock himself had gathered enough energy and strength in his arms to apply shampoo to his hair. Letting him finish the job himself, Jim quickly washed his own body.
“You can soak for a little bit,” he offered, turning the temperature up to Spock’s preference before stepping out. He left him to relax while he put on his clothes and went to change the bedsheets.
Jim cleaned up the vibrator and stored it away with the lube, and pulled the soiled sheets off the bed. He wandered over to the cabinet where they kept spares and brought out an identical new set to put on the bed. By the time Spock came out of the bathroom to dress in his regulation pyjamas, Jim had just finished slipping on the fitted sheet.
He hurried over to Spock and kissed the corner of his mouth.
“Feeling better?”
Spock nodded, dipping his head to nuzzle at Jim’s neck. “Come to bed, Jim,” he murmured. “I require… embraces.”
“Yeah,” the captain whispered back, stifling a laugh. Of course Spock was too refined to say ‘cuddles’.
Together, they climbed into bed, Spock curling himself around his bondmate’s body. He placed his head on Jim’s chest, right above his heart, and hooked his leg over the human’s thighs. Jim could feel the quick flutter of the Vulcan heartbeat under where his hand wrested on Spock’s waist, and he thanked the stars for the man he loved.
“Spock?”
“Hm?”
“I know you said you’re okay, but… I’m worried. Did I push you too hard tonight?”
In the dim light, Spock lifted his head, propping his chin up on Jim’s chest. His exhausted dark eyes shimmered with silent satisfaction, lips quirked up in a tiny smile.
“No, Jim. I enjoyed tonight.”
Relief passed through Jim’s body and he tightened his hold around his husband. “I’m glad.”
“Although,” Spock continued all of a sudden. “I would prefer if you could provide me with additional… cuddles.”
Jim couldn’t help the grin that lit up his face. “More cuddles, huh?”
Spock returned his head to his heart and threw his arm around him for extra measure. Jim too pulled him impossibly closer, breathing in the scent of his shampoo and body lotion. As the captain’s eyes drifted shut, he heard the tiniest softest snore from his husband.
“Good night, Spock,” he whispered into the darkness.
