****** The Other Andorian Incident ******
by seashadows
Summary
     Polina Chekova accidentally contracts a very embarrassing disease -
     fortunately, McCoy knows the cure.
Polina groaned, and shivered for the fifty-third time in fifteen minutes,
feeling goose bumps erupt down the length of her back. Her thin legs crossed
under the material of her uniform skirt. If she’d gone to have this looked at
earlier – but no, her stupid pride had gotten in the way, and now she was stuck
on duty for the entirety of alpha shift while her crotch burned like ice.

The worst part? She didn’t even know what had caused this. Like any other day,
she’d woken up, brushed her uncontrollable hair, eaten breakfast…mmm, that hard
purple fruit from Andoria had been delicious; she’d never had it before, and –

Andoria. The facts suddenly clicked into place inside Polina’s furiously
working brain; she felt like smacking herself on the forehead. She’d never been
there, but it was cold, wasn’t it? The only logical explanation for this
strange malady was that she’d picked it up somewhere, and the only variable in
her daily routine thus far had been in her food. Bozhe moj, what an idiot I am!
Didn’t Mama always say, “Polina, never eat something unknown”?

“Ensign, are you unwell?” Oh, of all the - Spock was noticing her odd cold-
crotch-induced shivers? Epitome of embarrassment; Polina felt her face flush.

“I…” For a long, agonizing minute, she contemplated saying no. Then she
envisioned eight hours of sitting there, alternately shivering and wincing in
pain, and decided to tell the truth. The worst that could happen was that Kirk
would leer at her legs as she left the bridge, and maybe Hikaru would laugh
about it later, and anything was better than this. “Yes, sir. I am not…I am
unvell. Please, may I go to sickbay?” In the quietest voice that she could
manage without actually resorting to a whisper, of course. Spock knew how to
keep his mouth shut, but perhaps not everyone else on the bridge could.

To his credit, Spock only nodded. “Who performs your duties during beta shift,
Ensign?”

“L-Lieutenant Broht, sir.” Ay-yai-yai, bad luck that another pain-shiver should
come upon her when she said the name. “I vill c-contact him, sir?”

“I got it,” Kirk called from the captain’s chair. “Don’t worry about it,
Chekova.” Despite the blush that spread from her cheeks to her neck and ears,
Polina felt herself grateful to Kirk, and the bat-ears he apparently possessed.
(How had he heard that, anyway? She’d said it to Spock only, in her lowest
voice.) “I’ll comm him. Just get to sickbay, okay? Feel better.” He smiled
encouragingly at her, the gazillion-watt smile that would’ve melted Polina had
her heart not been reserved for - save it, Chekova! Now wasn’t the time to
think about a stupid crush.

Even if, Polina realized in horror, he might be the one who looks at my – ah,
nyet! Chyort voz’mi! What if she was red and leaky and disgusting down there,
and McCoy had to see it? What if she freezer-burned his fingers? Was that even
possible? “Thank you, Keptin,” she managed. “I can go now, okay?” All right, so
lapses in Standard were pretty common when she was stressed – a notable example
was the infamous ‘I can do zat’ that Scotty kept quoting at her – but they were
still a pain in the sraka.

Kirk flapped a hand at her. “Go ‘head.” She was sure there was an innuendo in
there somewhere, but her lower half was shivering too hard (and her upper half,
by now) to figure it out. Why did this have to happen to her? Already, they
probably thought she was some kind of baby, and this running off to sickbay
wasn’t going to help.

Once in the turbolift, she clamped her hands between her legs, fingers rubbing
hard in an attempt to get rid of the horrible cold feeling. It didn’t work, of
course, not that she’d really expected it to. If anything, the sensation was
even worse; whatever she’d picked up wasn’t responding to stimuli. “Ai,” she
moaned, and whimpered when another twinge struck her.

The faint hope with which she’d held out, that Chapel or M’Benga or Ehlan would
be on active duty, evaporated as soon as Polina limped into sickbay, hard-
pressed to keep her hand from flying in between her legs again. McCoy, of
course, was the one who strode through the middle of sickbay to greet (or
whatever it was he did) her. “What’s going on, Ensign Chekova?”

This time, her shiver wasn’t just from the ice-cold feeling. His voice did have
that effect. “I…I am not…something is wrong.”

McCoy raised an eyebrow. “Yeah? Well, that’s real specific. Care to give me the
real problem?” Oh, now he thought he was some tongue-tied, lovestruck
teenager…wait. He was probably right, all things considered, but she did have a
valid reason. She did!

“Is down there, something is wrong,” Polina explained, and inwardly cursed her
pale skin, skin that flushed fiery red at the slightest embarrassment. If only
she’d inherited her mother’s olive skin – but apparently, that wasn’t to be.
“Is cold, oh! Wery cold. It hurts.”

“Dammit. That again.” McCoy rolled his eyes and reached for a tricorder, which
he turned on and moved around her person. “I was really hoping I wouldn’t have
to deal with this on the ship.”

“Vhat is it?” Oh, govno, it wasn’t cancer, was it? Or a flesh-eating virus?

He clicked off the tricorder. “Congratulations, ensign. You’re the proud owner
of a case of Andorian vagalgidosis.”

“Proud owner of Andorian wagi – vhat is?”

“It’s a disease that goes right to your reproductive organs. Meant to put ‘em
in a dormant state for a bit. Fortunately, the symptoms last longer than the
disease,” he added, probably seeing the horror-stricken look on her face. “Your
ovaries should be fine. But you’re gonna have to warm up somehow.”

“How I vill do that?” By now, Polina’s hands were shaking too much for her to
even contemplate putting them between her legs again. “Do you have hypospray
for this?”

McCoy shook his head. “Nope. Somethin’ Starfleet didn’t consider essential. If
you want to warm up, we’re gonna have to do it the old-fashioned way, and that
means a hot-water bottle.”

“You – you put hot vater on my –“

“You’re obviously incapable of doing it yourself,” he interjected, glancing at
her shaking hands, but his eyes softened just a bit. “Here.” He crossed to a
nearby cabinet and brought back a neatly folded blue sickbay gown. “Draw the
privacy curtain on that biobed, then strip down to your underwear and put this
on. I’ll make up a hot-water bottle.”

Well, it wasn’t as though she had any other options - ow - and this was
probably the only time he’d ever touch her intimately. “Okay, doctor. I vill
go.” She was quick to obey, drawing the curtain and stripping quickly. The size
of her breasts embarrassed her; with those goosebumps, they looked like a pair
of tiny chicken breasts or something. Or cherry tomatoes…eh, that one was an
exaggeration. Maybe. At least the gown covered them up.

“All right, ensign.” The privacy curtain was drawn back for a moment, and McCoy
entered, a water bottle in one hand. He sat down on the biobed next to her.
“Let’s see if we can’t get you fixed up. Spread your legs.” Was this
embarrassing him, too? His ears were nearly as red as Polina’s own.

“It is like opening to Keptin’s porno,” she pointed out. “’Spread your legs, ve
fix your nym…nymphomania.’” The similarity ended there, as the hot dark-haired
doctor in the vid had then proceeded to fuck his “patient” senseless, but
Polina thought it would be prudent not to point out that particular fact.

“Wh…what the – where the hell did you learn that?” McCoy sputtered, and nearly
dropped the hot-water bottle. “Has Jim been holding those damn porn parties?”

“No, I found by accident. I vas fixing something in ship network, and I found a
file.” This was one particular incident she didn’t care to recount, but perhaps
it was necessary. “It said ‘Sickbay Files’, so I thought vas important and
opened it. Vas porn.”

“Good God.”

Polina thought it was probably a good idea to just get this whole thing over
with, considering McCoy’s reaction. She scooted up against the biobed, drew her
knees up, and spread them apart – from that position, she could see McCoy
working and make sure he didn’t think she was immature or something. What if he
thought she was supposed to shave?

“This’ll probably feel a bit too hot at first, but that’s how you’ll know it’s
workin’.” Without any further warning, McCoy picked up the hot water bottle and
pressed it lightly onto her exposed pussy.

She yelped the moment it touched her – not just because it hurt, although it
did, but also because the combination of the heat and McCoy’s hands sent a
sharp spark of arousal up her spine. Thankfully, McCoy misunderstood. “Sorry,
but I gotta do it,” he said, and patted her knee in what seemed like an
apologetic manner. “It’ll feel better in a minute.” He moved the water bottle
slightly, gently rubbing it against her.

Polina’s “thank you” came out as a squeak. It was true that she was getting
used to the sensation, but how could she have anticipated getting aroused into
the bargain? Heat had sometimes done that to her, but it was rare. Very rare.
The last time it had happened, she’d been fourteen and sitting in a hot tub at
someone’s off-campus party, and hadn’t that been an intense orgasm she’d had to
hide.

“Y’okay, ensign?” Oddly enough, McCoy’s voice was as gentle as his hands. “Does
it still hurt?” He took the bottle away for a moment and turned it over, then
resumed the rubbing. “You should be thawin’ out about now.”

“Y-yes. I am, it is only…it feels strange. Yes.” She found herself canting her
hips forward, longing to thrust against that hot pressure (would his cock feel
so, inside of her?), but it was improper. Of course it was. She was an ensign,
and seventeen. “Does not feel bad.”

“Good to know.” He fell silent, having fallen into a rhythm with the hot water
bottle, and Polina closed her eyes. Sickbay was deserted but for the two of
them – where were the others? Off-shift? – and faintly, she thought she heard
the sound of the ship all around them, the sound of well-cared-for engines.

Her eyes were falling closed; she couldn’t help it. The heat, arousing as it
was, was soothing. But McCoy’s voice quickly brought her back. “It’s coolin’
down a little. You want some direct stimulation? It helps more without a
barrier.”

“Vhat?” She opened her eyes. He was looking at her expectantly – expectantly?
What? – still holding the water bottle between her legs. “Yes, okay. I…I take…”
Blushing, again, at how her command of Standard seemed to have deserted her,
she took her underpants off (at least they weren’t the pink ones with the bows
on them, right?) and put them aside.

The water bottle made an absolutely mortifying squishing sound against her when
he put it back in place. Ai, ai, don’t let him… “Ensign Chekova,” McCoy said
slowly, his voice a little different, somehow, than usual, “does this arouse
you?”

Polina had no choice but to answer. He already knew the truth, didn’t he?
Couldn’t be kept from him, with her pussy as wet as it was. “Yes. It is only,
I…I am aroused by heat, and you are wery handsome, and I am sorry.” The last
part was said in a tiny voice, as her head hung in shame. Of all the ways to
tell him she liked him, this had to be the worst.

“Well.” McCoy quirked an eyebrow at her. “Hell of a way to tell me, but no one
says I’m upset about it, Ensign.”

She shook her head. “Please, I am Polina.” He’d been examining her naked
private bits and noticed her arousal. First names were the least she could do;
it made her braver, at least.

“Polina. You’re sensitive down there right now, aren’t you?”

“Yes, but vhat does this have to do vith…”

“I can fix that.” A slow smile spread across McCoy’s face. “If you want me to,
that is.”

Well! Wouldn’t her mother be shocked if she knew what her baby was getting up
to right now. “I vant you to, but how you can do that?” Polina asked, and
echoed McCoy’s raised eyebrow. “It is big problem.”

“Easily solved, Ensign. I’m a doctor, not some inexperienced teenage boy. Close
your eyes.” She obeyed, quivering in anticipation, and cried out when she felt
his tongue touch her. He was right – he wasn’t inexperienced.

“You…you do this vhy?” she moaned.

“Because I want to,” she heard him say, and then his fingers were inside her,
too, and his tongue was lapping at her clit, sucking almost. Her breath came
faster, hips bucking up against him. Oh, she was sensitive because of this
Andorian thing. Embarrassingly so, but who cared right now?

“Doctor…I vill –“

“Call me Leonard.” And then he did something with his fingers inside her and
sucked hard on her clit, just like she’d fantasized alone, and she was crying
out in Russian as she came into his mouth.

“Govno – yob tvoiu mat’ – chyort voz’mi!” she moaned. Her hips rolled against
his hand and mouth, and chyort, but he knew how to use them, stroking her down
from the climax as surely as he’d brought her to it.

“You kiss your mother with that mouth?” he asked, amused, and she opened her
bleary eyes to see him smirking at her.

“Not anymore,” she responded, rather pertly considering the circumstances. “You
do not speak Russian?”

“I recognize swear words when I hear them. Must’ve been hella sensitive down
there, Polina.”

“Yes, I vas. Andorian thing made it so.” And that was the truth; he’d scanned
her, anyway, so he did know she wasn’t malingering. But bravery made her say
those next words. “I come again, and ve do the thing in Keptin’s vid?”

McCoy snorted and leaned forward to kiss her belly, surprisingly enough. “Yeah,
come back later today. But dammit, don’t invite Jim.”

“Ugh,” she shuddered. “I vould not.”

“Good.” He patted her. “Now get to your quarters and don’t even think about
going back on the bridge ‘til tomorrow. Doctor’s orders.” And that made her
shiver, with the promise embedded in the words.
