Chapter One

It was very late when Sarek awakened, again in irritation, with the same problem that had plagued him several times every night-a significant erection. He hoped the doctor had not noticed the bulge under his too-thin med jumper and bio-bed cover. Because it was so soon after surgery, he did not have the strength necessary to relieve himself so that he might be able to get some much-needed sleep.

He'd had erections before in his sleep, as almost any healthy male has, but he had more control of them and they had not been so uncomfortably demanding-or so immediately recurring.

He noticed that the erections occurred only minutes after he received his pain medication. Also, his…condition…was exacerbated by McCoy moving about, too often bending over in Sarek's presence. He couldn't help imagining stepping up behind the doctor, relieving him of his pants and starting something they might both enjoy. Sarek shook his head. The erections were causing more than physical discomfort and embarrassment; he was far too distracted by fantasy.

Nurse Chapel walked by and looked away a little too quickly. Sarek had tried not to stare at those firm breasts or significant amount of leg showing under the very short skirt that, obviously, men designed.

He could hear the two very quietly discussing something in McCoy's office, and had heard his name, but not much else. She had obviously seen that he was still awake even though she told him to try to get some sleep. He blushed at the thought that she must have also noticed his erections and was now discussing the issue with Doctor McCoy.

McCoy looked up as Nurse Chapel walked into his office with a slight blush. "Sir, the ambassador seems to be having…some difficulty."

McCoy immediately stood, concerned and said, "What kind of difficulty?"

"Not acute or immediate, but likely…sensitive. I'm concerned he's not getting enough sleep due to it, which of course could lead to more immediate problems."

"Sensitive?" McCoy looked baffled and curious. He had rarely seen Nurse Chapel embarrassed, and after what she had needed to do to the ambassador already, well, he couldn't think what might be more uncomfortable.

She swallowed. "He seems to be affected by the analgesic, in an unusual way."

McCoy lifted his eyebrows in expectation.

"The analgesic seems to be making him…aroused." She didn't meet his eyes and blushed clearly now.

McCoy smiled at her discomfort. With her feelings for, and utter admiration of, Spock, his father must seem almost god-like.

"I will deal with it," McCoy said.

Nurse Chapel looked relieved.

McCoy walked out of the office and into Sarek's room. "Hear you've been having some difficulty sleeping." The doctor stood a foot from Sarek's embarrassing "problem" and yet never took his eyes off Sarek's face.

Silence stretched between them. McCoy wondered if Vulcans masturbated. More to the point, if Sarek did, as he seemed more proper and stoic of any he had ever met. Not that it was relevant; he was likely too weak to be able to yet.

"Yes," Sarek said, "I am having an unusual side effect, I believe, from one of your medications."

"That has come to my attention," McCoy said straight-faced, and realized that had been an unfortunate choice of words.

Sarek, fortunately, didn't notice the unintentional innuendo. "It seems to have coincided with the analgesic," the ambassador said.

"Funny, it's never affected Spock this way, but genetically you are somewhat different."

"There are no alternatives to this medication?"

"Unfortunately, no; not on board. We've never had reason to consider an alternative."

Sarek looked pensive.

"Perhaps your wife could…" McCoy continued.

"She has been." Sarek sounded vaguely irritated.

"Oh."

"This constant…"

"Arousal?" McCoy offered.

"Yes...it is troubling."

"So even with your wife's assistance…"

"It occurs too often, and I am concerned with her need for rest..."

"I see. Perhaps someone else might be able to help." Likely most on the ship would gladly volunteer, but he sincerely doubted the ambassador would allow such. He couldn't help but be somewhat amused by the irony, but hoped the ambassador could be open-minded about this, as there weren't really any alternatives.

Sarek cleared his throat. "I would rather not involve another."

Now that he thought about the timing of Sarek's analgesics, the erections, and his own visits and walk-throughs, McCoy realized that he had inadvertently exacerbated Sarek's problem. His eyebrows rose at this new bit of information, and smiled as he considered another alternative.

"Perhaps we don't need to involve others," McCoy said, and gave a long look at Sarek's erection and then his face.

Sarek flushed clearly now and swallowed but said nothing, though his now-straining erection made clear his interest.

McCoy noted Sarek's erection as it grew and twitched in response. He also noticed Sarek seeing him staring at it and smiled at him. "I think my assistance would be mutually beneficial."

"You have obviously gathered your effect on me, Doctor, and I cannot say that I am not …interested…as, obviously, I am…"

McCoy felt himself hardening at the prospect.

Sarek continued, "…but I would have to question the appropriateness, legality, regulations, ethics, morality…need I go on?" He didn't sound pleased by his arguments, almost frowning as he looked to the mound and then purposefully, away.

McCoy found himself momentarily distracted by the possible opportunity to plow the ambassador. He had to force his hands not to reach and fondle that mound, and he made a concerted effort to keep his eyes from staring at it. God, as his doctor, he would normally never let his mind focus on such, but he did want to fuck this man.

"You are a powerful man that I have difficulty influencing, even with regard to your well-being when I am trying to protect it, so coercion or undue influence is irrelevant. Your wife has tried to help as best she could and it hasn't been enough, especially during the night. You still need the analgesic." Here he paused significantly. "You must sleep or there will be serious consequences after such major surgery."

Sarek seemed to sober at the reminder that he had almost died, and looked up at the doctor. "Perhaps you are right, but…"

"This is difficult for you, I realize that. You are a very private and reserved man. But think of this as you would any other necessary medical procedure and allow me to attend to it as such."

Sarek looked even more uncomfortable at the prospect.

"No one else needs to know. I'll give the nurses on duty long breaks and I doubt anyone will drop by at 3am."

Sarek appeared to relax a little at that.

"Let me just take care of some details." He slipped out of Sarek's private room. The door swooshed closed. He gave the two nurses on duty long breaks, explaining that he would monitor Sarek's condition personally, collected some lubricant from a drawer, then strode back with a bit lighter step than he had intended.

Doctor McCoy glanced at the ambassador, feeling empathetic toward what must be humiliating for the Vulcan. "Is there anything I can do that might make this easier for you?"

Sarek closed his eyes. "Perhaps once we are past these preliminaries; I believe the actual event will be distracting enough to solve my…discomfort."

The doctor slipped the cover off the bed, spread the slip-open fly and snagged Sarek's large erection that popped forth and held it tight.

Sarek, eyes still closed. He sucked in a breath.

"Do you have a preference of what you want me to do?" McCoy tried to lessen his smile of satisfaction, anticipation, and triumph. He felt guilt over his seeming bounty, but it was truly for Sarek's own good, and completely necessary.

"Anyway you please, Doctor. You will be doing me the favor. I will do as you request."

"Hardly a favor when I'm likely to enjoy it more than you, it appears."

Sarek smoothed away his scowl. "That hardly seems likely, but thank you for your graciousness."

The doctor tried to quell the gleam in his eye. "So you'll allow me to choose the possible means of relief?"

Sarek nodded, too intent on the grip on his penis. "I must warn you, one climax will likely not cure the problem.

One man's problem is another's dessert, McCoy thought but didn't say. Let Sarek feel grateful for what he viewed as a medical treatment. He had always appreciated Sarek's attractiveness from a distance, but having him prone beneath him and completely vulnerable while he administered to different aspects of his body before, during, and after the heart operation had pushed his thoughts to the more selfishly, wantonly erotic.

Sarek was no longer the attractive, well-groomed, and powerful man on the arm of his beautiful wife, but displayed beneath him in all of his glory, no detail kept from McCoy's purview. He could not help but try to remember this scene for masturbation later.

He remembered the ambassador was suffering while he privately relished and gloated, and decided the quickest relief might be to taste the man until he exploded in his mouth. He didn't notice that a figure stepped closer in the darkened back lab off of Sarek's room that led to the back entrance of sickbay, a private entrance very few had authorization to enter, and none permission. The figure froze and watched from the cover of darkness and lab noises about him.

McCoy knelt down and began his treatment and immediately felt Sarek's back and neck arch as the Vulcan moaned. He sucked and licked as the ambassador suddenly bucked into his mouth and yelped and froze as the pain reading shot up. "Now let that be a lesson," McCoy warned as he took a break from his sucking. "It's too soon since your operation to move about. You will have to fight your natural impulse to thrust or to reach for me, that includes any thrashing about when you climax. I don't want to have to strap you down."

"Understood, Doctor." Sarek had likely been extremely frustrated because after only a short time his legs started to shiver and spasm, and he moaned loudly as he came.

McCoy tasted a Vulcan for the first time and found it pleasant and hoped to taste much more of Sarek before he was released from sickbay. Sarek shivered with his spent adrenaline and jerked every now and then. With gasps and pain readings blips from his body's recovery, McCoy licked his penis clean, and it started to perk up again almost immediately.

"Thank you, Doctor," he said huskily.

"Oh, I've only just begun, Ambassador," the doctor said just as huskily.

"I am pleased to hear that."

"Your penis is not the only part of your anatomy that might afford you some relief." McCoy enjoyed the anxious look that brought, though it was only momentary.

"I will cooperate fully, sir, with whatever you decide. I am in your debt."

McCoy knew that Sarek would feel that way, but it gave him a little thrill to hear him say it. It was rather like a brilliant chef asking you to sample his chocolate mousse and giving you a gallon, as a favor to him. McCoy had to quell the laughter that had almost bubbled out at the sight of the ambassador prone, and still sexually frustrated, awaiting McCoy's choices as to what to do with him next.

McCoy had a gleam in his eye as he eyed Sarek's med jumper a jumble about his body.

"I will need to remove the jumper," McCoy said distractedly.

"Please do so," Sarek said a little breathlessly.

He grinned as he took Sarek's legs that were already spread in response to his urges and gently slid him to the end of the bio bed. He pulled apart the tear-away fabric connectors between his legs and from his chest and belly. The med-jumper fell away to reveal his full nakedness. Sarek's watched the doctor's efforts with hooded eyes.

McCoy stepped over and retrieved the lubricant, setting it beside Sarek on the bed, then unfastened and dropped his pants, releasing his erection. "Since you, sir, can't get up to mount anyone for awhile, I will take that advantage." He eased Sarek's thighs up as he watched for signs of pain on the monitor above his head, careful not to shift his torso. He positioned his penis, already slick with ample precum in the excitement of his imminent entry.

Sarek only stared at McCoy and licked his lips. "Should I consider this another facet of my treatment, Doctor?" he said, his tone still very Vulcan, but unsteady which seemed to excite the doctor even more.

McCoy smiled at the ambassador's obvious excitement as he squirted some lube on his fingers and started to massage the man's hole. He first tried a little soft manipulation, and heard Sarek's breathing accelerate and felt his sphincter relax. He wiped his slick fingers on his penis.

He knew enough about Vulcan physiology to know how to make the reserved Vulcan cry out in ecstasy, it was just a matter of time, effort and patience since his patient was so recently operated upon. The walls were soundproofed and the bigger the climax, the more release Sarek would have.

He pressed his erection gently into the prone man and heard him immediately moan. Concerned, he checked the monitors and saw that the pain from his penetration registered only slightly, yet Sarek's pulse rate quickened appreciably and his legs relaxed to spread further. McCoy curled his arms around Sarek's thighs, eased forward and fully penetrated him, feeling his significant heat the length of his cock.

Sarek moaned and shivered with his excitement. "Please, Doctor, don't stop." His breathing had accelerated rather dramatically. McCoy smiled at the increased respiration reading above.

McCoy had never fucked anyone actually hooked up to the bio-bed and decided it would only add to his enjoyment as he saw the fluctuating bio-scans. He could read Sarek's responses like a damn book, even if he went into Vulcan mode while he fucked him.

He thrust into Sarek slowly and gently, and watched the man's skin flush a pale green as he grew more excited at McCoy's rhythm. He watched the heart rate rise slightly, then slightly again as Sarek gripped the edges of the bed and shivered every now and then with the adrenaline build-up. He saw Sarek's semi-erect penis grow and stand up large and stiff. He smiled; he would get to that again soon enough.

He increased the pace ever so slowly, and a little moan escaped as Sarek tilted his head back a little. McCoy thought about how he should keep these readings for later and check them for any irregularities, and for his own interest and study; Vulcans were so private, and there was so little research on their sexuality.

He watched his subject spread beneath him, then watched the heart rate as he increased his tempo again. He enjoyed the control. He knew Sarek wanted it faster and harder. Saw his dark eyes look to him pleadingly, but he knew he couldn't. Now, if he was still interested once he had recovered…

"Please, Doctor, increase your thrusting," Sarek said, as if reading McCoy's thoughts.

"I wish I could Sarek, but I could too easily hurt you. You'll just have to let your arousal grow more slowly than is likely comfortable for you." McCoy watched as he realized the man could only lay there and take what came, his breathing increased little by little until it was infused with pants and groans. McCoy longed to thrust into him with abandon, harder than he would with any human, as Vulcans could take that kind of force easily, but Sarek was far too premature in his recovery.

Sarek grasped the bed as the soft sound of flesh slapping flesh and their moans filled the sickbay. "Doctor, please, soon."

"Sarek, you know that I can't do that, as much as I'd like to. Hurting you to give you release is not a reasonable bargain. Breathe deeply. Try to keep your mind off the need to climax." He felt Sarek's body shiver and was relieved that he, himself, was close, as it seemed so was Sarek. The wonderful thing about fucking a Vulcan, McCoy had read, was that the physical contact added the partner's excitement to the Vulcan's. Sarek was experiencing McCoy's excitement through his touch and that would likely bring him additional release.

The moans grew louder as Sarek's back and neck arched and he surprised McCoy as he cried out and shuddered, just before McCoy came within him and cried out himself.

The figure stepped away quietly and left through the back entrance of the sickbay.
