"Sulu, you have the con." "Yes, Captain." Jim Kirk smiled broadly as he strode across the bridge into the turbo lift. It had been a good week, with all of his ship's missions succeeding. He smiled even more wolfishly at what this meant for him. As the turbo lift doors whirred open, he saw a familiar pale face look up at him.

"Captain."

A one word acknowledgement, Jim frowned. Spock had dropped the habit of calling him Captain since they had bonded, seven years ago. Reaching for their mind-meld, Jim jumped at the roiling emotions pouring off of his mate. "Mr. Spock?" he queried, his tone inflicting just a tint of worry. "Are you alright?" Spock's usually dark eyes seemed blacker than usual. "I am… Fine." he choked out, "I just require a period of rest." Jim reached out and took his husband by the arm, his crystal blue eyes filled with unspoken hurt. "Spock, what's wrong?" he pressed, determined to get an answer from his first officer. Spock twitched away, his face registering a turmoil of pain and darker emotions.

As fast as the change had appeared, the half-Vulcan buried the feelings again. "Jim, it would be most unwise for you to do that again." he stated calmly, then seeing Jim's worry increase, "I must go to sickbay, I require Mr. McCoy's assistance." "I'll come with you." Jim said firmly, his eyes never leaving Spock's. He couldn't leave his t'hy'la in this state. "I want to help." Spock flinched, and when Jim finally reached out across their meld, he felt his lover slam up his inner walls. "Please… Please Jim. Let me go." "You know I can't do that, Spock." Their arms barely brushed together, but it was long enough for the crippling wave of pain and lust to bridge their closely-knit meld. Spock's eyelids fluttered as he slid to the ground.

Jim noted the flickering eyes, how Spock's breathing increased, and when his mate began slithering out of consciousness, he was at the ready to catch him. Adrenaline hit his blood like a flood tide in spring. With his life-mate in his arms, Jim Kirk ran with fear pounding inside of his head. Sickbay doors slid open with just a whisper, and Jim found himself screaming for Bones before his foot even entered the door.

Leonard McCoy, the senior medical officer of the Enterprise, felt a chill hit him before he even heard his best friend's piercing cry. As soon as the swish of the doors hit his ears, McCoy was running full tilt at the nearest biobed. As he whipped around with the bed prepared to receive a patient, the sight he encountered knocked him breathless. His Captain and long-term friend was carrying what looked like a mint-green Vulcan, and the look of agony and helplessness on Jim's face stopped McCoy in his tracks. "What -" he croaked, as Jim sank with the Commander onto the biobed. "And you didn't tell me?" the medical officer demanded, realization of what had happened clicking in his head. "I can't - I didn't - We couldn't, god I'm so sorry Bones, just please, fix him." Jim stumbled over his words, on the verge of hysterics as his bond mate lay prone before him. "Get outta my sickbay."

Hours later, a tall, coffee-colored woman strode down a hallway and abruptly halted at the slumped form. "Captain?" she said, uncertain what to do. Blue eyes slowly raised to her brown, full of such a deep pain, she found herself tearing up. "Lieutenant." said Jim Kirk, his voice betraying none of the pain his eyes showed. "How is he." The question was more of a statement, and Lieutenant Uhura cleared her throat. "How is he, dammit!" Jim yelled, beginning to shake. Uhura jumped and kneeled before Jim, "You need to come with me, Captain."

"He's dying from lack of sex." "Yes." "You can't be serious." Jim Kirk's eyebrows rose in a way that nearly mocked his partner's. McCoy sighed, rubbing his forehead, "I had to call in a couple favors to figure it out. Vulcan's apparently… Undergo it every so many years. I never would have suspected… I thought the man was half-human, dammit!" "Hey, hey, Bonesy, I know." "You know." "I know." "Goddammit Jim! What the hell is this, you couldn't have told me three hours ago?" the doctor's pacing stopped as he spun to glare at Jim. "Well… We need to talk." "We need to talk, my ass."

McCoy pulled Jim into a quiet corner of the sickbay, his eyes flaming. "Now what the hell is going on, Jim? First of all you come in cradling your first officer unconscious like you've been married for years, now you're telling me you knew what was wrong with him all along-" "Bones, Bones, stop. I didn't know all along. I knew- Well, wait. I need to go back. Seven years ago…" McCoy snorted in exasperation, "Oh goodie, story time." Jim looked at the floor, scuffing his feet. "It's called Pon Farr. But I didn't know it then. I don't think Spock even knew it then. Salek called me." "Salek? Now you're telling me Spock's father knew about this?" McCoy bit off, then let his anger simmer back down. "Yes, Salek. He said Spock had spoken to him earlier that week about how he had found a suitable mate, because he had felt the stirrings of Pon Farr. I hadn't noticed the first time, I thought Spock was just tired and needed reassurance. But when I patted his shoulder, apparently he had gone all Vulcan skin-mind reader on me and seen some stuff he wasn't supposed to." Jim blushed bright pink, still scuffing at the floor. McCoy just goggled as the realization of what Spock must have seen hit him. "And well… Yeah, it kind of, you know, triggered it." Jim ended lamely, unwilling to look at his friend.

McCoy opened and closed his mouth several times, confusion evident on his face. "But, okay, so what happened after you triggered it?" The Captain's breath hitched, and he turned an even brighter shade of red. "Well… Remember that week I took off for medical leave? And I asked you for some mild pain killers afterwards?" Now it was Leonard's turn to blush, the pieces coming together in his mind. "OH. Oh. So it's… It's as bad as they say?" his voice shook a little, betraying his discomfort. "Yeah… Uh. Yeah." Jim just settled with that.

Across the bay, Spock shifted a little as Jim's voice reached his ears. His eyes snapped open, a spark burning in them that Leonard didn't like one bit. "Jim, Jim he's awake. Do I need to, should I restrain him or something? Will he hurt you?" worry crept into McCoy's voice, and he backed up a few steps. "No, no he won't intentionally hurt me." Jim's voice took on a strange tone, his eyes glazing over as Spock growled low in his throat. "But Bones, you need to leave. Now. Please." Leonard McCoy did not need to be told twice.

"I was just kicked out of my own sickbay?" McCoy said, his brow crinkling in confusion and uncertainty. A moment later, a noise came from inside the doors that made him cringe and hurry away.

As soon as the doors to sickbay whooshed shut behind McCoy, Jim turned slightly and cringed at Spock's penetrating stare. "Spock… Spock?" he asked quietly, to receive a purring from the bed where his mate lay. "Spock… If you can hear me… Please calm down…" he pleaded, staring into the chocolate eyes of his lover, searching for any respite. Spock's voice cracked a little, his eyes losing some of their fire, "J-Jim, I cannot hold off. The p-plak tow is too strong, I will give you as much time as I can." Jim felt a pang of fear, and tried desperately to stave it off before it could taint their mind-meld. I am here, t'hy'la. A familiar voice reached into his mind, wrapping him in comfort. I will not hurt you this time.

Jim took a shaky step towards the biobed, feeling the immense waves of pain and desire that were flooding his mate's entire being. Desire for him. Desire to feel Jim. His breath wavered, as the lust washed over his body as well, feeling a fraction of the need Spock was feeling. Apparently, he wasn't moving fast enough to suit Spock's needs, because seconds later he found himself pressed into the mattress of the biobed, Spock's toned arms pinning his wrists to the sides of the bed. Spock, Spock, I'm afraid- his mental voice shivered as a feline tongue licked down his throat. I know, came Spock's response, full of guilt and pain for Jim, I am trying, just relax. The sound of ripping fabric reached Jim's ears, and a wash of cold air rushed over his chest. He shivered violently for a moment, until Spock pressed his inhumanly warm body against his lover's.

Spock… Jim reached for the meld, seeking the comfort and warmth of Spock's mind. A rush of affection and love poured through the meld, as he felt Spock understand his need. Then he felt lips upon his neck, hands upon his sides moving down. "Oh… Hng." Jim bit his fist, feeling his partner's desire seeping back through the meld. Another ripping of cloth and Jim felt his pants and boxers leave his body, but he was no longer cold. "Spock, oh god-" his words cut off as he forgot all Standard. "I find your lack of articulation fascinating." Spock said from his position between Jim's legs. "In fact, I believe I find it what you humans call desirable." Jim's legs shook from the pain and pleasure radiating from Spock's cock. "Fuck… Spock… Move dammit!" he choked out a few words then gave up speech entirely.

Spock gripped his hips, a wolfish smirk on his face, "As you wish, Captain." Jim heard a high pitch wailing as Spock began slamming his hips flush into Jim. Realizing it was him, he strained to bite his fist again, until Spock pinned him back down. "No," he snarled, "I want to hear you." Spock changed angles slightly, and Jim found Spock's name being drawn from his lips in a screaming cry. There were no longer conscious thoughts in their meld, just pure lust and pleasure. Jim's eyes rolled back into his head, the feeling of being fucked and fucking becoming too much for his body to handle.

Jim curled his fingers into the sheets of the biobed, ripping tiny holes where his nails were. His back arched to meet Spock's burning body, and Spock slammed them together without ever changing his bruising pace. Jim screamed again, but this time he was unable to form a single word. Spock smiled and kissed down Jim's neck, feeling the vibrations of each noise his mate made. Jim's hands hit Spock's back, his nails pulling down the Vulcan's heaving, toned muscles. He arched his back again, his entire body shaking as his lover slid in and out of him. Jim felt the ripple run throughout Spock's body as he lost all control. The mind meld between them was now more of a shared conscious, the feeling of being fucked senseless by Spock and the feeling of burying deep into the tight heat of Jim.

The emotions and contact became too much all at once. Spock thrust once more, hard into Jim before spilling into him with a roar of satisfaction. Feeling Spock's orgasm in his mind made Jim come, covering Spock's body and most of the biobed. Spock slowly came down from his high, Jim laying perfectly still under him. When Jim thought it was mostly over, he reached carefully up to Spock's face, stroking his pointed ears. Spock softly leaned down to kiss him, and Jim felt the unexpected wetness on his lover's face.

Jim snapped back, his breath trembling. "Spock…" he whispered, "Are you crying?" "Vulcans do not… Cry." Biting his lip, Jim moved under Spock slightly. He winced and whistled under his breath at the sharp pains. Spock looked at his mate finally, tearstains evident under his eyes. "How bad… How bad is it?" he asked, brokenly. Jim pulled Spock down beside him and began stroking his face. "It isn't… It's not… Don't worry about me, Spock. How are you? Why didn't you tell me earlier?" "I thought, I wanted to prevent this as long as possible. I hurt you." the Vulcan's voice was raw, the human side of Spock was emerging. "It's not as bad as…Well…" Jim trailed off, realizing the last time Spock had gone into Pon Farr was not a good thing to compare this to. "It wasn't that bad. It was just… Rough."

Spock looked at Jim, his eyes hooded. Feeling for their mind meld again, Jim let his feelings seep through. He tried holding back the initial pain and terror, but Spock's superior mind strength gently pushed until he showed Spock everything. A quick breath from Spock was all Jim heard. He closed his eyes, snuggling closer to his husband. "I'm cold." he stated, knowing Spock could never resist the chance to cuddle with him. As Spock wrapped tentative arms around him, Jim placed soft kisses up and down the strong limbs of the man he was bound to. "I love you." he murmured, sleepy in the warmth of his t'hy'la. Through the meld, Jim felt Spock's affection at his use of the Vulcan term, and heard his response, "And I, you." Then, blissful sleep brought momentary peace to the couple.
