OFF DUTY

Jim sat on the bed in his quarters, clad only in a pair of black Starfleet-issue boxer briefs. He crossed his legs and twiddled his thumbs in his lap. It was late in the evening, well past the end of his shift. Silence enveloped the room, except for the soft rumble of the ship's engines, which he always found calming. He needed calming at the moment; shortly, Spock would emerge from their shared bathroom and they would be having sex for the first time.

They had been in a relationship for only a short while now, but decided over a game of three dimensional chess the afternoon before that the time was right. Jim didn't know why he was so nervous; it wasn't like this was his first time. It was, however, the first time he had ever been with a Vulcan. He had no idea what their mating rituals were like outside of Pon Farr. He mentally cursed himself for not having done research beforehand. What if he did something Spock didn't like and ruined the moment? This wasn't like any of the flings he had had in the past. He loved Spock. He wanted this to be special. To help achieve this, he had lowered the lights in his quarters to a calming level and raised the temperature slightly so Spock would be comfortable.

He knew Spock would probably be a while longer; he had informed him that he wished to shower beforehand, as Vulcans preferred to be very clean before mating, so Jim shifted to one side and propped his elbow on the small ledge behind the bed. If he listened closely, he could just hear the soft patter of water hitting the floor. It reminded him of the sound of rain back on Earth.

Finally, the shower shut off and several minutes later, the door to the bathroom slid open with a hiss. Spock emerged, wearing his black undershirt and standard issue underwear, both of which hugged his lean body in all the right places. Jim smiled when he saw him framed so elegantly in the doorway. Silently, Spock crossed the room and sat down on the bed next to him. Every hair was neatly in place. He smelled fresh and clean, with a hint of the Vulcan spice tea he so often drank.

"Jim, before we begin, there is something I must confess," said Spock, eyes cast toward the hands folded in his lap.

"What is it?" Jim brushed the backs of his fingers across Spock's cheek.

"I have never done this before."

"You mean, with a human?"

"No. Not ever. I am...a virgin, as you might choose to put it. I am familiar with the mechanics, of course, but..."

"But what?" Jim asked softly, sensing Spock's nervousness.

Finally, Spock looked at him, his eyes searching, innocent, almost nervous. "I don't quite know what to expect."

Jim smiled tenderly and stroked the back of Spock's neck with his thumb. He did his best to push calmness and reassurance across their newly established bond. "Then let's find out together." He leaned close and nuzzled the side of his face.

Jim's warm breath tickled his skin as he trailed light kisses along his jawline. When he reached his mouth, Spock immediately kissed him back, slow and gentle. Their lips made tiny clicking sounds as they parted, only to be sealed back together over and over. Spock marveled at how soft the Captain's lips were. Jim was the first person he had shared a human kiss with, but in the short time they had been together he had become damn good at it, as Jim chose to put it.

Jim sighed as their lips slid perfectly together. He let his fingers wander through Spock's hair, tracing them along his neck, around the shell of his pointed ear.

"Jim, wait." Spock pulled back suddenly.

Jim worried he had done something wrong already. "What is it?"

"There is one other thing." He stroked Jim's bicep, breathing deeply. "Which one of us will penetrate?"

Jim raised a contemplative eyebrow. "I hadn't really thought about it. What do you think?"

"Well...while I do wish to explore various sexual acts with you, I'm not sure that being penetrated is the first one I would like to try. If that's alright with you, of course."

"That's fine. Whatever makes you comfortable."

"But, are youcomfortable?"Spock squeezed his shoulder.

"Yes." Jim smiled to reassure him. "I trust you." He brought Spock's hand up to his face and kissed the backs of his fingers. He did know that Vulcan hands were very sensitive and considered one of their erogenous zones, and he intended to take full advantage of that.

Keeping eye contact with Spock, he uncurled his hand and deliberately kissed each one of his fingertips, delighting in the way the Vulcan's lips fell open slightly. Venturing down to his palm, he kissed and mouthed and breathed warm puffs of air across the delicate skin.

"Jim..." Spock moaned his name.

"Am I doing it right?" Jim asked, grinning.

"Yes..." Spock seemed almost mesmerized by what he was doing.

The way his fingers pressed into is wrist. His tongue expertly slipping between each of his digits. If he kept it up long enough, Spock was sure he could come from this stimulation alone. A groan caught in his throat when Jim lightly bit down on the soft part at the heel of his hand. He immediately soothed it with his tongue. That tongue. Those lips. Spock was almost dizzy.

"Jim, please..." he gasped.

"Please, what, my darling?" Jim shot him his best seductive look.

Spock quirked an eyebrow and the next moment, Jim found himself being pulled into a blistering kiss. Spock gripped the back of his neck with his Vulcan strength, but loosened a moment later, perhaps fearing that he'd hurt him. He repeatedly pressed his fingers into Jim's golden skin in an almost massaging manner, stroking his rounded human ear with his thumb.

Jim moaned into his mouth, kissing back fervently. A warmth spread throughout his body at having Spock like this, so close, so intimate, in the quiet privacy of his quarters. Wanting as much contact as possible, Jim shifted and straddled Spock's lap, not once breaking their kiss. He teased his tongue at the seam of Spock's lips and was immediately granted access. He gently explored the warm, wet cavern of Spock's mouth, savoring every tiny sound the Vulcan produced.

When they finally had to part for air, Jim's eyes fluttered shut at the feeling of Spock's growing erection pressing against him. Only two thin layers of fabric separated them. He gently rocked his hips and Spock's head fell back in a sigh. Seizing the opportunity, Jim attached his lips to Spock's neck. His pulse throbbed furiously beneath the skin. He bit and sucked on that pulse point, causing Spock to gasp and cling to him. He delighted in the way Spock, normally so calm and composed, squirmed underneath him, undone by the smallest touch.

Jim pulled back and saw the beginnings of a greenish bruise forming where his lips had been. He felt so pleased with himself. The mark was well above the level where Spock's uniform could hide it; everyone he passed would be able to see it and know who put it there.

Wanting more skin to explore, Jim felt for the hem of Spock's undershirt and worked it upward, grazing his fingertips across the cool skin underneath. Spock shivered under Jim's touch and his sultry gaze. Hundreds of tiny bumps pricked across his skin - "goosebumps", he had heard humans call them. Jim kissed him, deep and passionate, as he raised his shirt further, parting when the material brushed their chins. Spock raised his arms and allowed himself to be disrobed. The removal ruffled his bangs slightly.

Discarding the shirt to the floor, Jim drank in the sight of Spock's naked torso, lean, slightly sculpted, his hairy chest heaving. Jim's boxers suddenly felt uncomfortably tight. He swooped in and kissed along Spock's collar bone, almost drunk off the scent of his skin. Spock's hands slid across his shoulders as he traveled lower to his nipples. He teased one experimentally with his lips and tongue, gently kissing, circling, sucking it between his teeth.

Spock gasped. He caught a glimpse of that hot, wet muscle sliding between Jim's lips, lavishing him with attention. Gods, the things this man could do to him! He whined when Jim's mouth left him, but it immediately reappeared at his other, neglected nipple. He squirmed as tiny waves of pleasure washed over him, pooling at his groin.

When both of his nipples were thoroughly ravished, Jim moved lower, leaving a trail of open mouthed kisses all along Spock's abdomen. Spock tensed and sucked in his breath as Jim rubbed his face against the prominent bulge in his underwear. His hot breath permeated the fabric, causing a shiver to travel up his spine.

"Jim! Come here, let me touch you," he breathed.

Jim bit his lip and grinned as he climbed back up Spock's body. "I've gotten you properly flustered, haven't I?"

Spock's hands found his backside and pulled him tighter against him. The Vulcan's chocolate-brown eyes burned with desire. Jim cradled his face and kissed him again. He sighed and darted his tongue inside Spock's mouth as he felt those nimble fingers spread across his hips. They traveled upward to his lower back, but didn't stay there long, as they slipped under his waistband. Jim felt them kneading, exploring...until one eased into the cleft between his cheeks and brushed his opening.

"Spock!" He broke their kiss, gasping.

"Is this manner of stimulation pleasing?" asked Spock, his voice deep and lustful.

"Yes!" Jim managed to choke out as the finger pressed and massaged. He leaned into him, his shaved chest against Spock's hairy one.

"I believe the most comfortable position for your first penetration might be on your stomach," Spock said.

Jim felt him begin to maneuver his body around, but stopped him. "No! I want to see you." He touched his forehead to Spock's and brushed his lower lip with his thumb. "Like this." Though loathe to break their contact, he rolled over onto his back and brought Spock with him.

"As you wish," Spock said and quickly stripped him of his underwear.

Jim closed his eyes and sighed at the feeling of finally being free of the restricting garment. A moment later he sensed Spock's presence hovering over him. The sight that met him was nothing short of god-like. Spock's sharp Vulcan features, including the tips of his ears, flushed the palest shade of green, his lips swollen and pink from kissing, his normally perfect hair slightly disheveled. But his dark eyes had cleared, if only for a minute.

"Jim, I must warn you, Vulcan males have a noticeably larger length and girth than the average human," he said.

"I'm sure I can handle it." Then he remembered, "I sneaked this out of the sick bay for the occasion." He reached up to the small chest on the ledge behind the bed and produced a tube of personal lubricant. "Don't tell Bones."

A tiny smile tugged at the corners of Spock's lips. "I'm nothing if not discreet." He leaned back on his knees and slowly pulled his underwear down. If Jim didn't know any better, he would say Spock were attempting a strip tease for him.

Jim could not stop his eyes from widening when the Vulcan cock arched free. He had seen Spock naked in the showers at the gym before, but he had never seen him erect. He had to be at least seven inches. And so thick. The hard column flushed a darker shade of green than his ears and was covered with smooth, irregular ridges all the way down.

"May I prepare you?" Spock asked, reaching for the lube.

"Please do,"Jim thought as he handed it to him. With his heart thudding in his chest, he spread his legs while Spock flipped open the tube and squeezed a bit of the clear substance onto his fingers.

Setting the tube aside, Spock looked at him for a second and tilted his head. "Jim...I sense that you are afraid. Do you not wish to continue?"

"Not afraid. Just nervous." Jim glanced down at what awaited him.

"I promise I'll go slow. I won't penetrate until you're ready." Spock brushed his inner thigh with a soothing hand.

Jim nodded and swallowed. Reaching between his legs, Spock carefully spread the lubricant around. Jim gasped at the coolness of his fingers. He bit his bottom lip as one of them slipped past the tight ring of muscle. This was an entirely new sensation; he'd never had anything inside of him before. He rather liked the feeling of the single digit moving gently in and out. It didn't take him long to relax enough to accept another. He moaned and lightly stroked himself in time with Spock's careful movements.

"You're so beautiful like this, you know? Moaning...spread out...laid bare beneath me." Spock's voice was intoxicating.

"Oh, Spock..." he sighed. "That feels so good." He clenched around the scissoring fingers.

"Would you like another?"

Jim curled his lips around his teeth and nodded. His hand jerked around his cock as a third finger was carefully inserted. He didn't know how Spock was lasting so long without touching himself; he saw copious amounts of precum gathered at the tip of his cock, a bead sliding down the shaft. Spock continued to work him open, resting his other hand on his hip and tracing tiny circles with his thumb. Jim almost lost himself in the pleasure. He tried to thrust down to bring Spock's fingers deeper within his body. He threw his head back, moaning, and had to tear his hand away from his cock, lest he finish too soon.

"Spock, please...I'm ready!" He pleaded.

The corner of his mouth twitching, Spock removed his fingers and reached for the lube again. "Would you care to do the honors?" he said, offering it to Jim.

Jim didn't need asking twice. Sitting up, he took the tube and squeezed a generous amount into his palm. Spock moved closer, balancing himself with his hands on Jim's shoulders. The tip bobbed so close to his face.

Jim shot him a glance as he worked the lube up and down his throbbing green shaft. His hand barely wrapped around it. The deep, guttural moan that escaped Spock's lips was perhaps the most alluring thing Jim had ever heard in his life.

Once he was satisfied that Spock was slick enough, he leaned back, wrapping his hand around Spock's neck to pull him down on top of him. They kissed and Jim let out a breathy moan at the feeling of Spock's cock stroking between his legs. He brought his knees up so they brushed along Spock's sides. Tearing himself away from Jim's lips, Spock took his erection in hand and guided it into position.

Jim felt it pushing. Pushing so slowly and with such care, until the head slipped inside him. He gasped. It kept going, stretching him, inching deeper. Spock's fingers were nothing compared to this. He didn't know if he could take all of it. Spock peppered his jaw and neck with soothing kisses.

"Relax, ashayam. I'm right here," he whispered.

Jim spread his legs wider and shifted, trying to suppress a groan. He squeezed his eyes shut. Finally Spock's hips came to rest against his. Panting, he tried to force his treacherous body to relax. He so wanted this. He wanted to be with Spock in this way, in every way.

Spock kissed his forehead, then his eyelids. Jim mentally praised him; so much raw strength lay hidden in those Vulcan limbs, and yet he kept it restrained just for him.

"Am I hurting you?" he asked.

Jim was sweating now, a combination of the higher temperature in the room, nerves, and his own burning arousal. "A bit," he choked out. "But I'm fine. Please don't stop." He stroked Spock's biceps and looked at him with those beautiful hazel eyes that always made Spock weak in the knees.

Spock stroked back a lock of hair that had fallen over Jim's forehead, as it so often did. In doing so, his body shifted and he delivered the tiniest of thrusts to - to somethinginside Jim,causing him to cry out and cling to Spock.

"Jim! What's wrong?" He started to pull back, but Jim locked his legs around him.

"N-nothing! Do that again!"

Raising an eyebrow, Spock experimentally rolled his hips. Jim gasped and dug his nails into his back, a sensation he found he enjoyed.

"Harder! Please!" Jim pleaded.

Letting out a moan almost like a growl, Spock finally let loose. He pounded into Jim's tight, warm body over and over. His hands curled around the bedsheets until his knuckles turned white.

Jim arched his back and clenched hard around Spock; the pain was beginning to ebb away, mixing with the pleasure in the most dizzying combination. He didn't think such sensations were possible. Spock's ridges caused every nerve in his body to come alive. He desperately dragged his nails up and down Spock's back. He saw muscles rippling in his biceps and his shoulders.

"Spock - oh, fuck - ah! Keep going! Yes - harder!" Jim pleaded beneath his First Officer.

"Is that an order?" Spock slowed his thrusts and raised a seductive eyebrow.

Jim almost came right there. He pulled Spock closer so their lips were millimeters apart. "I order you to fuck me until I scream your name to the stars."

"Acknowledged. Captain."

Jim's eyes snapped shut and he cried out as Spock drove into him once more. This is what he would think of every time Spock addressed him on the bridge. Every time he saw the Vulcan bent over his science station, he would be drawn back to this moment. The thought threatened to overwhelm him, but he steeled himself to make it last longer. Please, just a little longer.

Spock snapped his hips forward as he listened to Jim's escalating cries, his ragged breathing. His cock throbbed at the sight of his Captain writhing beneath him, at the feeling of his human body tightening with every thrust. The look on Jim's face set his blood aflame; the man's brow furrowed, his eyes squeezing shut, his mouth hanging open in ecstasy. His skin glistened in the low light surrounding them.

"Spock! I'm close! I think I'm -" Jim never got to finish his sentence before orgasm overtook him. He threw his head back and shouted, his fingers digging into Spock's arms. He shot hot ropes of cum all over his own chest and stomach.

Spock watched as his Captain came undone beneath him. It was perhaps the most glorious sight he had ever laid eyes on. Jim clenched around him so hard he thought he might faint. All it took was one final desperate cry of "Spock!" to send him over the edge. He groaned and emptied himself deep inside Jim's body.

Once their orgasm released them and they were spent, they collapsed in a heap of trembling limbs. For several minutes thereafter, the only sound in the room was their heavy breathing. They held each other, Spock's lithe, Vulcan body against Jim's smaller, softer human body. The air ghosted across the green scratches that now covered Spock's back.

Finally, Jim said, "Spock, as much as I would love to stay like this all night, you're kind of squishing me."

Spock mumbled something and carefully rolled to the side, his cock making a wet sound as it slipped out of him. Without even thinking about it, Jim curled up against his side and was immediately encircled in his arms. He placed one hand just below Spock's ribs and felt his heart thudding, fast and steady. He laid his head on his shoulder, eyes suddenly feeling heavy.

Spock gently stroked his golden hair. "That was a...very pleasurable experience," he said.

"Yes...very," Jim whispered. "Hey, Spock, what was that Vulcan word you called me?"

"Ashayam?"

"Yeah, that one. What does it mean?"

"It means 'my beloved'."

Jim smiled tiredly. "I think I could get used to that."

"I truly never thought I would get to use it."

"Why not?"

"I never thought I would feel strongly enough towards anyone. I didn't think anyone would want me."

"What?" Jim propped himself on his elbow. "What are you talking about?"

"I have never felt like I belonged anywhere. I have always felt self-conscious among other Vulcans. I was made fun of. Some said my Vulcan blood was...contaminated by my human ancestry. And humans usually stare at me. I think it's because of my ears."

"Spock, you are the most attractive person on this ship. Anyone would be lucky to have you. I know I am," Jim said. "And I love your ears."

A green blush spread across Spock's cheeks. "You do?"

Jim nodded. "I think they're sexy." To prove it, he leaned close and nuzzled one of those graceful points. He kissed it. Very gently rolled it between his teeth. He detected a sharp intake of breath on Spock's end.

"Jim, I should warn you, if you continue on your present course, I may become aroused again in a very short time."

"I'm counting on it."
