Chapter One

"My T'hy'la" Spock whispered as he caressed Jim's flushed cheek. They lay in bed together, completely intertwined as if an unbreakable knot. Jim was now kissing the ends of Spock's pointy ears and admiring the greenish glow of his skin. Making love was Spock's one emotional pleasure that he simply could not hide. He desired Jim in ways he never thought possible, and this brought on the brunt of his Vulcan affliction.

Pon Farr. The name of what haunts Spock so often in his subconscience. He knows that he yearns for Jim in so many ways, but he cannot satisfy his hunger until they are bonded. He leans up on his right elbow, and stares into his mate's blue eyes.

"I had a thought that we might marry soon", Spock said completely serious toned.

"Are you proposing to me?" Jim asked with that devilish smirk of his.

"It seems only logical considering our connection. I want you forever; there is no doubt in that my T'hy'la."

"Well then, I would like you to properly propose to me. As a human, it is custom that you get on one knee, state my name, and ask for my hand."

"Jim, is that really necessary?" Spock hesitated; he did not understand this ritual.

"Absolutely", Kirk kept his confident grin.

So Spock slid off of their bed with nothing but his boxers on. He continued to stare at Jim's blue eyes, and then proceeded to profess his wish to marry him. There was no ring to be given as Spock was not familiar with this custom, but he did offer Jim a Vulcan lyre song; the one thing that he knew melted Jim into a puddle. The lyrics flowed through him in a way no Vulcan could understand; there was love and emotion in his melody, and Jim reveled in it.

The two stuck together their index and middle fingers as a sign of affection, and crawled back under the satin covers. Spock stared at Jim once more...only this time, there was determination in his chocolate brown pupils. There was fire spreading through his skin and stomach. It burned so hot that it was almost an unbearable pain. He wanted Jim so badly, and now more than ever.

"Jim...I..." Spock began to gasp as the fire spread and became stronger.

"Spock? What's wrong? What can I do?!" Kirk was baffled at his mate's sudden change in state.

"I know I just asked you to marry me. But can we do it now? May we bond now? I need you, Jim. I need you so much. If I do not fulfill this need, I shall die. It is a genetic curse for my race, and I have apparently inherited it. Not telling you seemed the logical path as I was unsure of how our relationship would play out. I know now that you are my one true T'hy'la, and that is evident as my body feels like someone has torched it with lust for you. If we do not bond, and I do not take you fully right now, my mind will ravage me and I shall perish."

"Spock! I love you so much...I would never delay this for one moment. I want you for eternity, and if right here in this ship quarters is where we seal our fate, I could not be happier. Do not make yourself suffer anymore", Jim spoke with such intensity he too was almost on fire.

Spock's lips curled into a slight smile; raised eyebrows. A sign he was filled with utter joy.

Chapter Two

Spock ripped the two uniform shirts from Jim's back, revealing the tan muscles that cascaded down his backside. Jim was so sweaty; his desire must have gotten the best of him, and there was no temperature control anymore. Spock began to bit his lips and ears violently like an animal. His long, pale fingers stroked Jim's chest as he began to kiss him down a line to his pants.

"I promise, Jim, I will not hurt you. No matter how ravenous I become, I will never harm you."

Jim could only moan and nod in acceptance as he was filled with lust so deep he could not keep himself together. Spock snapped off the buttons of his black pants, and unzipped them with his teeth. Jim's breathing became more heavy, and the length now at Spock's eye level was hardening quickly.

"Spock. Do it now."

Spock's fingers went straight to Jim's mind-meld points. They both closed their eyes and gasped at the strength of the touch. Spock's concentration never faltered, and Jim simply took in all of the emotion that swept through him. They were bondmates now; forever and always. The two slowly opened their eyes, and began to laugh with smiles strung across their faces. Their connection had never been more strong, and that was only about to increase with their next decision.

"Jim. My pon farr is still quite strong. I cannot fully recover until I have entered you and fulfilled my desires. However, being that you have never been with a vulcan or a male, I am not sure"

"Stop right there", Jim spoke softly while pressing a finger to Spock's lips.

His own lips replaced his finger as they shared the most heated kiss they had ever experienced. Kirk took his pants completely off, and lay on the bed, waiting for Spock to take charge. Spock acknowledged. He climbed on top of Jim and began to rub and pull at his still hardened member. Jim arched his back slightly, and grabbed the now loosened sheets as he groaned in delight.

"Are you ready, T'hy'la?" Spock whispered in Jim's ear as his body pressed even harder against him.

"More than ever."

Spock shoved his length into Jim's opening ever so slightly. He rocked back and forth a few times to loosen him up. Then, with much force, he entered Jim completely.

"AH SPOCK!" Jim practically screamed with simultaneous pain and pleasure.

The smile on Spock's face grew wider, and did not clear away for many seconds. He had finally done his duty to himself and Jim. They were united in an unbreakable way, and that satisfied the Commander fully. Spock did not stop rocking back and forth while inside his mate. He came just seconds before Jim did, and they both wailed in delight. Labored breathing accompanied the sweat pouring off of their bodies as they lay once more endlessly intertwined.

Spock went to grab towels for the two of them, but Jim grabbed his hand before he could exit the bed.

"Don't leave. Not now. Not ever. Stay here and cuddle with me."

Jim leaned in and kissed his partner feverishly once more. Spock decided that leaving at this time was indeed not logical. So the two stayed covered in their own cooling fluid and stared up at the ceiling. Jim was nestled in the crick of Spock's neck. It was so warm and welcoming, and Spock's arm reaching across his waist only made it more so. The two remained in that position for several hours. They didn't need to speak or move; just hold each other and feel one another's breath and heartbeats through their skin. The moment was perfect.

Chapter Three

*Knock, Knock, Knock*

"Jim, what is the matter? How can I assist?"

"You can't!"

"T'hy'la you have been vomiting for four mornings in a row now. I think it is time we seek the attention of Dr. McCoy."

"No. I'm fine. Really."

"Jim, I am not going to have a quarrel with you about this any longer. We are going today."

Jim moaned in agony; Spock was unsure if it was out of illness or his unwilling participation.

"Well, well, if it isn't the Captain himself? What can I do ya for?" Bones smiled at him sheepishly.

"He has been experienceing severe vomiting for four days now, and it has not ceased. He runs a slight fever, and his joints seem to be swelling", Spock retorted so robotically.

"It's a stomach flu, Bones. Just check me out so Mr. Type A over here can get on with his life", Kirk rolled his eyes as if unamused.

"Let me get my super-technical equipment out", Bones winked at Jim, "Yep here it is! My own personal med-scanner. Lay down on the biobed Jim and stay still."

Bones took the scanner and went from Jim's skull down the vertical line of his body. He was casually examining the screen until he stopped dead on Jim's abdomen. He raised it back up to his chest, and back down to his stomach once more. Eyes widened, he just stared at Spock.

"What is it?" Spock's concern was rising from his voice.

"You're pregnant, Jim," he stated while still locked on Spock's now stone gaze.

"No, I'm not! Check that dumb thing again. I'm a MALE human Bones. You're wrong."

Spock tightened his grip on Kirk's hand. Both sets of their eyes went cloudy and dark as the confusion set in. It was impossible. It could not happen. He was a male. He was human.

"Jim, put your legs in those stirrups by you."

"Seriously? What, you gonna do an exam now?"

"Well, yeah you smart-ass. I have to be sure."

Bones peered into the underneath of Jim's hospital gown. Once more, his pupils dilated at the sight of it. He had seen a vagina beneath Jim's penis. An entire other reproductive system! No. NO. This was not happening! Bones explained his findings to the pair, and their eyes just stared at him blankly.

Suddenly, a smile broke out on Kirk's face. He began to laugh and cry while still holding Spock's hand. Spock looked at him with a quizzical gaze. What was this outburst of happiness? Jim is mutated, and yet he looks so joyful.

"Relax Spock. We're having a baby!" Jim said still laughing.

"Jim. Did you even know about yourself?"

"Sorta. My mother told me there was a genetic mutation spread from a radioactive spill. But we were not sure if it had affected me as I was only an infant. Maybe that made me more susceptible. But no, I was unaware. So when Spock and I had sex three weeks ago, he entered my vagina? Is that what you're telling me? Oh that's rich!" Kirk said sill laughing.

Bones just shook his head in disbelief. How had these two really not known? I guess the whole heat-of-the-moment thing really distracted them.

Spock finally came to the same conclusion as he kissed his mate's temple and smiled. They were going to be parents! It was unplanned, and unforseen, but who cares? They had bonded as permanent mates that night. It seemed more special that their child be conceived then. It was like a sentiment for the both of them. Jim was staring at his stomach now; stroking his fingertips along the spot Bones had stopped the scanner at. He was not paying attention to anything else around him; he was going to be a father. Or mother? Whichever, there was a life inside him. One so rare and perfect he couldn't believe it was reality.

"Do you wanna know the gender?" Bones said, interrupting the couple's racing minds.

"Yes", they both agreed.

"It's a girl!"

The smiles on Jim and Spock widened to where they almost cracked. Tears fell once more from Kirk's ducts, and Spock gently kissed him on his grinning lips. A baby girl. Magnificent.

Chapter Four

Kirk went about his Captain duties the next morning with no hesitation. Spock would want him to do the same as he was the head of the Enterprise. The two of them would telepathically speak of their child, and wink with smiles from across the Bridge. Crew members could not know about this; it may undermine them as leaders since their priorities have changed.

Jim was sitting at his chair when he suddenly grabbed his stomach and winced in pain. Spock felt him, and rushed to his side.

"I'm fine", Jim spoke as his back straightened back up.

"Captain, should I take you to Sick Bay?" Spock whispered with a concerned tone.

"No. I'm really fi...AAA!"

Kirk doubled over in the chair gripping his abdomen with every finger bone he had. Sweat beads began to roll off of his forehead, and his vision became blurry. He could see Spock's anguished stare as he scooped him up in his arms and ran to Sick Bay.

"Doctor McCoy!" Spock screamed as the medical doors swooshed open.

"Oh God! What's happened to him now?!" Bones shouted back with concern.

"I am not sure. He was smiling at me across the Bridge, and then he clutched his midsection and writhed in pain."

"Okay. Put him on the biobed. We need to check him NOW", Bones replied.

Jim was conscious this entire time, but the words were blurred. He didn't truly understand what was happening. Next thing he knew, Spock placed him in the hospital bed and grabbed his left hand as McCoy scanned him.

What Bones found was nothing he had seen before. Jim's blood was turning green and filled with copper...like that of a Vulcan. However, it only ran from the baby to the uterus and back. The rest of his blood was all normal and human. He had two blood streams running through him, and the cells didn't know which to attack.

"Jim, can you hear me?" Bones spoke as Kirk's eyes slightly opened.

"Jim. You have to terminate this pregnancy. It is going to kill you. You have to. Your body cannot cope with this," he said with great sorrow in his tone.

"No. NO. I will not," Jim was more awake now, and very determined.

"T'hy'la, you must. I cannot lose you," Spock gripped his hand tighter.

"Spock, I love you. But this baby inside me...I can FEEL it. You know that...you can hear it through my thoughts. I will not get rid of it."

"But Jim, you are only two months pregnant. Still the first trimester..."

"I don't care! I don't care if it is two days! Spock and I conceived a miracle, and I will keep that miracle until it literally kills me."

Spock dropped his hand from Kirk's and left the room. The pain led to emotion, and he just could not handle that.

Chapter 5

The next few days were silent. No telepathic thoughts, no smiles, and no affectionate bonding. Kirk remained in Sick Bay, and continued to contract in pain for hours at a time. Spock would sit by his side without touch. He loved Jim, and wasn't going to leave him there alone.

"Spock! Hold my hand!" Jim fluttered around the bed gripping his entire belly. He couldn't take it anymore.

Spock did as he was told. The pain he felt through Jim was almost unbearable. He kissed his forehead, and laid a hand on the slightly swollen abdomen.

"Ahhh..." Jim sighed.

"What?" Spock responded.

"Whatever you just did. It made it subside. The pain is hardly anything now. I think you calmed the baby."

Smiles broke out on their faces once more. Spock's touch was what their daughter wanted. She wanted her Vulcan father to touch her so that she did not feel so foreign.

"Bones!" Kirk shouted in delight.

"What?! God dammit Jim I cannot handle any more complications"

"Just shut up and look!"

Bones saw their serene expressions and made the connection. They explained to him, and his eyes widened. If that wasn't true love, what was?

Spock's hand went back to Kirk's left one, and he stared at the flesh covered ring finger. He had never given him an engagement ring!

"I shall return," he spoke calmly and went to his quarters.

Spock returned with his mother's sapphire, gold-banded ring she had given him when he was younger. It was intended for his T'hy'la...and he had forgotten about it until now. Sometimes, thinking of his mother hurt too much, so he closed off that entire part of his memory.

He returned to Sick Bay within minutes and practically ran to Kirk's bedside.

"Jim, give me your hand," Spock said as Kirk smiled with curiosity, and Spock slid the ring onto his finger.

"I apologize for its feminine qualities, but I did not intend to be with a male when I first thought of my bond mate," Spock sheepishly grinned.

"It's perfect," Kirk beamed as he admired his new accessory.

Chapter 6

Three months went by, and Kirk was still chained to his quarters. Spock and Bones were not going to let him command the ship. Mr. Sulu was in charge as Spock demanded he stay by Jim's side 24/7. Nothing less.

Kirk's belly was expanded to the point where he was showing now. He would lay his fingers atop his skin and feel the baby move within him...then the fits would come. Screams filled his lungs, and he would grab himself and curl up in a ball. The baby's blood mixed with his never seemed to calm. Spock would rush to his side, and place his skin on Jim's stomach to ensure that the pain stopped. He couldn't bear seeing his mate in such a state. Tears rolled down Kirk's face. When would it stop? Five months of this and still going. Poor Spock hardly ever slept out of worry.

"Thanks, honey," Jim whispered as the pangs died.

"As always, anytime," Spock whispered back brushing his free hand through Jim's hair.

It killed Spock. These fits occurred at least eight times a day, and never got any better. The two blood streams refused to coincide, and one was determined to beat the other out. They should have terminated the pregnancy...

"Jim. Are you sure you do not wish to end this?"

"What are you talking about?"

"The pain you feel. It comes through my head constantly. How can you bear it?"

"I bear it because OUR child is inside me. She is scared, Spock. She needs you because she doesn't feel safe with my body. Being more Vulcan makes her more vulnerable than if she were human. You cannot blame her for that. Besides, the pain fits are normal to me now. Sure, it doesn't change how much it hurts, but I have you. And that is all I need to feel safe."

"Fine T'hy'la," Spock said with anguish on his face. But he kissed his forehead anyway and curled up next to him; placing a hand on his stomach so Jim could sleep knowing a fit would not occur as long and Spock was holding him.

"Can we just stay like this forever?" Jim smiled up at Spock; intertwining their free hands together.

"Of course. As long as you wish," Spock said as he gave him a heated kiss.
