This story is set during the episode AMOK TIME
Christine Chapel took a deep breath before she entered the Vulcan's quarters. Her heart was racing, her palms sweaty, she couldn't remember the last time she'd been this nervous. The soft folds of the light blue nurse's uniform rose with the swell of her breasts as she took a second breath and then finally entered the dimly lit room.
"Mr. Spock?" She called out in a low voice.
When no answer was heard, she took a hesitant step into the dimly lit quarters. A wave of hot air hit her as she stepped from the cool confines of the hall. It was obvious that the environmental controls had been set for "Vulcan Normal."
Her eyes quickly adjusted to the dimness and she could see the outer room of the two room quarters was empty. A slight sound from the adjourning bedroom caught her attention. Gripping the hypo in her hand ever tighter, she followed the sound.
"Oh God!" Christine exclaimed in a hushed whisper as she entered the bedroom and saw the Vulcan lying naked on the bed.
A layer of sweat covered his body, matting the thick layer of black hair that covered his chest. Moving closer, her eyes couldn't help but notice the enlarged state of his penis. If Spock had been fully human, the 10 inch length of his shaft would've been considered excessive. From her studies of Vulcan anatomy, the Nurse knew he was only average sized.
Christine jumped back as Spock moaned in his sleep. Almost afraid to wake him, Christine gently brushed his wet hair way from his eyes. In her mind she could imagine the agony he was going through.
On her first deep space assignment, Christine had responded to an emergency on a small Vulcan research station on Amin VI. There she had found one of the male Vulcans in a state very much like Spock's. In order for her to help him, one of the other Vulcans had explained the concept of Pon Farr to her. Their own healer had been killed in the accidental explosion that had brought her ship to Amin. Afterwards, she had respected their wish that she never speak of it again to any off-worlder.
Yet, as a result, Christine knew more about what was wrong with the Enterprise's First Officer than Doctor McCoy did. In her hand she held a hypo with a drug that would help decrease a Vulcan's sex drive. It was an obscure medication, only used at the time of Pon Farr.
"I can't bear to see him in agony." The blonde nurse thought to herself.
How many years had she been in love with this man. A love that she knew would never be reciprocated. Yet, even knowing this, she would still make any sacrifice for him.
"Nurse Chapel?" Spock said in a low voice as he opened his eyes.
Christine didn't say a word as he sat up on the edge of the bed. His lack of clothing in no way detracted from his bearing. In fact it enhanced it, since even in his weakened state, the strength of his body was evident. His eyes drifted from her face to the medical instrument she held.
"Calnizine." She replied to his unasked question.
"Then you know?" He asked.
"I encountered it once before, a long time ago." Was the reply.
With that she raised the hypo to his shoulder and injected the drug. Spock seemed to react ever so slightly from the injection, a sign that even his famous control slipped at this time.
"Thank you ... Christine." He said, the faint trace of a smile on his lips.
Hearing her name from his lips brought more joy to her heart than a declaration of love. In all the years since she had come onboard, it had never been anything but "Nurse Chapel."
About ten minutes passed and Christine began to become worried. The medication should've begun to work by now, instead his condition seemed to be worsening. A glazed look began to come over his eyes and he began to moan once again.
"This shouldn't have happened." Christine thought. "I'd better get Doctor McCoy."
Twenty minutes later, Leonard McCoy walked out of Spock's bedroom, a worried look on his face. Christine had been waiting in the outer living quarters since summoning the CMO. She had explained Pon Farr to the Doctor upon his arrival. Much of it he had already figured out. While he couldn't exactly condone his nurse's actions, he more than understood her desire to help Spock under conditions that would preserve his dignity.
"It's that blasted human/vulcan mix in his physiology." The doctor exclaimed as he walked up to Christine. "The medication you gave him isn't having any effect on his human half."
"Then what can we do?" She asked.
"Damned if I know." McCoy said. "They didn't exactly cover this at Starfleet Medical. I'm going back to sickbay and see what I can come up with. But the bottom line is that we're still fifteen hours from Vulcan. Even though I know Jim and Scotty would burn out the warp drive trying to get him there a little faster, we may just have to face the fact that he's going to burn out before we get there."
"Should we move him to sickbay?" She asked.
"No, there nothing more that I could do for him there." McCoy said, the frustration in his voice evident. "With Spock's passion for privacy, it's better off keeping him where he is. Just stay with him and monitor the situation."
A quarter of an hour passed and Spock's fever continued. Christine desperately searched her mind for a solution. Then a sudden thought caused her to rethink the situation.
"We've been looking at this all wrong," She said to herself. "We've been looking at this as if it was a virus or infection. Something that wasn't normal for Spock. But what we really have here, stripped of all the alien customs and physiology, is an incredibly horny man. A genuine case of the fictitious disease that young men even in this age tried to convince women existed. It was called many things, but always came back to original name, blue balls."
Spock needed to mate. If he didn't, he'd die. It was that simple. Christine didn't know if a human female could take the place of a vulcan during the Pon Farr, but it was worth a try. After all, Spock's mother was human.
Suddenly aware of a touch at the base of his cock, Spock snapped awake. Looking down, he instantly understood what Christine was attempting to do.
"Christine, no." He protested. "It isn't safe for you to..."
She silenced him with the touch of her fingers against his lips. Then she replaced the hand that had been stroking his cock with her mouth.
