The Art Of Desire.

Summary: This takes place a few years after 'The Art Of Science.' Lillian Rose has become the assistant science officer on the Enterprise and Eric and Michelle have become assistant geographer and sociologist. Lillian has decided to adopt the ways of the Vulcans and she and Spock are scheduled to return to Vulcan at the time of Pon Farr to be married. However, along the way the Enterprise gets stranded on a strange and hostile planet where Spock is forced to fight for Lillian and risks trapping the ship and the crew if he cannot win, and is also faced with the prospect of his own death should they not reach Vulcan in time...

A/N: Also, I have deliberately skewed the time line a bit in this for sake of the plot. Lol. Since Vulcans only have Pon Farr every seven years and it was supposed to be a five year mission, and 'Amok Time' was set however many years into that mission I'm just gonna go with the theory that the mission got extended by a few years or something. Lol.

"Mr. Sulu, how lung until we reach Vulcan?"

"Approximately thirteen hours Sir, we are right on schedule."

"Good. Mr. Chekov, increase speed to warp six."

"Ay Sir. Increasing to warp six."

"Captain... May I be excused from the bridge? I feel a mild hot flash coming in and I would not wish to endanger the crew..."

Kirk looked up at the Vulcan and nodded. "Of course, Mr. Spock. Take as long as you need."

"Thank you Captain."

"Miss Rose, you can take over Mr. Spock's instruments."

"Yes Sir."

Spock left the bridge and returned to his quarters, the hot flash now a raging inferno as his temperature ratcheted up a few degrees above normal. Spock remembered the last time he had felt the fires of Pon Farr burning through his veins and he did not wish to have a repeat performance. He only hoped Dr. McCoy would have the sense to stay away, but as the Captain was likely to order him to check on him he doubted it. McCoy entered his quarters a few moments later, proving him correct.

"Spock, the Captain asked me to..."

"Yes, I know, Doctor. Please, get on with it."

"Snippy this morning aren't you? Oh well, let's see that temperature of yours..."

Spock lay on his bed and grudgingly allowed McCoy to do his job and refrained from commenting when he said; "Temperature... Jesus, Spock! You're burning up! Any normal man would've been boiled alive from the inside out!"

"Quite correct Doctor, however I assure you it is perfectly normal for me, as a Vulcan, at this time. I also suggest you and the Captain refrain from having any further contact with me from this point on. If you must send someone in, I would suggest Lillian as the logical choice in my current state."

"So, basically, that's a nice way of telling me to get out?"

"You could say that Doctor." McCoy sighed, shook his head and left.

As soon as the door to his quarters closed, Spock gripped his head in his hands and groaned loudly. He was already becoming edgy and it would not be long before his ancient Vulcan blood fever took hold. Spock experienced a sudden, heated flash of primal rage and flung an empty plate across the room, punctuating it with a loud, feral cry...

"He won't see us, Jim. He practically told me to stick it when I went in there before, although I will say that he did it very eloquently."

Kirk sighed. "Well, we can't force our presence on him Bones. We both know that Spock isn't himself at the moment. I guess there's no sense in antagonizing him..."

"Antagonizing! Jim! Last time he was like this he hardly needed antagonizing to act like a complete barbarian! What makes you think this time's gonna be any different!"

"Because, Bones, this time we're going to get him to Vulcan soon enough. It's only a few more hours, honestly, how much damage can he do in that time?" At that moment there was a loud 'crash' from somewhere down the hall and Kirk, McCoy and Lillian all looked at each other, running toward the sound of the commotion.

"...What do you mean the engines malfunctioned! You're the engineer! So do something about it!"

"Now, there's no need ta shout, Mr. Spock! Honestly, I'm doin' everythin' I can..."

"Well it's not good enough!"

"Do yeh think you could do a better job then, do yeh Mr. Spock? Because if that's the case then I highly doubt that..."

"Do not disrespect me authority Mr. Scott or I shall...!"

"What Mr. Spock! I'm not the one actin' like a... Well, like a bloody barbarian!"

Spock practically growled at him and slammed a fist into the wall, backing Scotty up against it.

Kirk, McCoy and Lillian rushed over to them and Lillian put a hand on Spocks arm, speaking quietly to him; "Now, Spock! What kind of a way is that to behave!"

The Vulcan turned to her and the uncharacteristic rage faded from his dark eyes. "You are right, of course. Mr. Scott, I apologize for my brutish and unprecedented behavior." He followed Lillian from the corridor, nodding to the others as he passed. "Doctor, Captain."

Scotty stared after Spock for a moment and shook his head. "What in the blazers...!"

"Don't worry about it, Scotty. He's not himself at the moment."

"Ay, I can see that Sir. How long until we reach Vulcan?"

"About another twelve hours or so Scotty."

"Thank god we only have ta put up with it 'til then!"

"Yes, Scotty, indeed. Er, what was Mr. Spock saying about the engines?"

"Ah! Well, you're not gonna like this Captain, but systems 'ave bin droppin out all over the place, Sir and so far I haven't bin able ta pin it down! I'm divertin' all unneeded power to the warp engines Captain, but I don't know fer how long it'll last! If we lose those engines Captain, it's going to be a very looong trip to Vulcan Sir, if we ever get there at all!"

"Right, try and maintain it Scotty and keep me informed. I'll be on the bridge."

"Ay, Captain, I'll do my best..."

Lillian sat next to Spock on the bed and put her hand to his head. "Oh, you're boiling hot, Spock! I can barely touch you!"

Spock nodded and gave a short cry, reeling forwards, suddenly and Lillian put an arm around him to steady him. "Is it always like this?"

He nodded. "Always."

"Oh, I do wish you would show me what's going on in there!"

Spock placed his fingers at her temple and Lillian gasped at the mixture of messed up thoughts and emotions running through him. "Oh, Spock!" Lillian held his face in her hands and kissed him, softly and the Vulcan stroked his fingers through her long auburn hair, sighing quietly.

"You know, Lillian, you shouldn't take advantage of emotionally compromised Vulcans like that..." He was smiling slightly as he said it and the unburied desire bought on by the Pon Farr was making him want to do things that he never thought he would feel compelled to do...

"It is only taking advantage if you do not know what you are doing..."

"I know what I am doing, but I am not entirely in control of it..." He was still smiling slightly and his hands were still in her hair. "I..."

"Yes Spock?"

"I... Feel that I want to do something I probably should not... But, for you... It could be a long time, between... And I do not think that I wish to become a father at this point in time..."

"Oh! Yes, I suppose it could be a long time for me and I do not expect to bear child just yet! There are ways to prevent it, until we are ready..."

"There are, yes..." Spock leaned closer to her, speaking quietly in her ear. "But are you ready for that? Once we go that far there is no turning back, Lillian, for either of us..."

Lillian pulled back far enough to look in his eyes and replied; "I know. But you forget, that for me, we are already past the point of no return."

"Of course..." He leaned in again and touched his lips to hers, the ancient desire flaring again, making his blood boil with the passion of a thousand years past, the tightly controlled emotions, long dormant in his mind finally breaking to the surface, with the call of the ancient blood.

Spock laid her gently on her back and Lillian ran her hands through the Vulcans short hair, the inky strands never seeming to fall out of place as he moved over her, sliding her uniform shirt off and carefully removing the rest. Lillian removed his own uniform, with slight fingers and the growing desire in each of them was fuelled by the descovery of new flesh and unfamilier bodies.

The universe dropped away then, as the Vulcan entered her, his own, heated passions matched by her desire to finally be one with him, to be with him not only in body, but in mind and heart and soul. Spock began to meld with her, fully, linking their minds completely and thoroughly, as the desire crashed through them, powerful and blinding in its intensity.

They let go in a joint and satisfied cry, fluids and voices mixing to further complete the bond and for a moment, the meld was so complete that neither could tell where one would end and the other began as, for a moment, they became one being; sharing thoughts, minds, souls and bodies, as the ancient blood of their ancestors burned and pounded in their veins.

Spock remained within her for a time, until the wild, uncontrollable desires had begun to fade, lessening to a soft heat in his blood rather than a raging fire. He left her slowly, gently, before laying beside her and taking her in his arms, the fire cooling more slowly in her, and he held her close, breathing deeply the scent of her skin and hair.

Lillian rolled over to look at him and said, quietly; "Maybe I should have rescued you sooner..."

Spock shook his head. "I do not think it would have made a difference to the outcome..." He was smiling softly now, one of the few times he had ever truly done so and Lillian smiled back, stroking his hair, peacefully. Spock allowed himself a small grin and said; "If you ever tell the Captain that I am capable of feeling like that, I will personally see to it that I never do again..."

Lillian smiled coyly at him and replied; "Don't you worry, Mr. Spock... Your secret's safe with me..."
