****** Three Sentence AUs ******
by orithea_(orphan_account)
Summary
     From a tumblr meme: send me a pairing and an AU and I'll write a
     three sentence fic for it.
     Each chapter will have the pairing and AU and any warnings listed
     first. Most of these could fall in the PG range, but a few are
     explicit.
Notes
     Prompt: Johnlock, arranged marriage AU
***** Arranged Marriage AU *****
The man was short, going grey and a bit soft about the middle, and apparently
thought that dressing smart meant a plaid button-up and a jumper that was
frankly hideously offensive in its very ordinariness—how could Mummy possibly
think he’d be taken with him enough to agree to this arrangement?
Sherlock could feel it when he gripped the man’s hand to shake: calluses,
wearing off now from disuse but clearly from regularly handling a gun
and—Sherlock rubbed his own finger along the man’s index finger just a shade
longer than proper—something else that piqued his interest enough to ask, “John
Watson, just how many men is it that you’ve killed?"
"Seventeen," John answered steadily and without hesitation, which made Sherlock
appreciate him more, “that I know of at least—you can’t always tell in a war,
can you?"
***** Omegaverse AU *****
Chapter Summary
     Prompt: Johnlock, Omegaverse. Explicit.
"No, no, don’t let it dribble out," John said anxiously, shoving two fingers
back inside Sherlock’s arse.
"You’re not breeding me," Sherlock huffed, “you know it makes no difference
whether it stays in or—"
"It does make a difference—you smell amazing when I’ve come inside you, like
all those omega hormones are just intensified by me," John said, and buried his
face in the crook of Sherlock’s neck to worry the skin with his teeth and
inhale to prove his point.
***** Moriarty/Adler Potterlock *****
Chapter Summary
     Moriadler, Potterlock
“You’re the other prefect?" Irene asked, eyeing Jim’s green and silver badge
with her mouth twisted into a moue of distaste.
"Try not to look so disappointed, Adler." He grinned and raised a brow, “why,
just think of all the trouble that we can get into with the two of us in
charge."
***** Guinea Pig AU *****
Chapter Summary
     Prompt: Mystrade, Guinea pig AU.
Chapter Notes
     I have never laughed so hard at a prompt before. Bless.
"Are you going to eat that courgette?" Mycroft asked, eyeing the slice lying
untouched before Greg’s paws.
"I was," Greg sighed heavily, “but since I like you, you can have it."
"Good—perhaps I’ll ease back on the human’s surveillance on you in repayment,"
Mycroft said magnanimously.
***** Mystrade Medieval Era *****
Chapter Summary
     Prompt: John/Greg, medieval era, but I accidentally read Mycroft/Greg
     and did that first, so here's a bonus.
"It’s generally considered poor form to sleep with your Lord to gain favours,
you know."
Greg gave Mycroft a slow smile. “Well, you do what you must when you’re a
youngest son, and it’s not exactly a hardship for me, is it?"
***** Johnstrade Medieval Era *****
Chapter Summary
     Prompt: John/Greg, medieval era.
"You saved me," John gasped and clutched at his friend’s tabard, the white of
its fabric and the gleam of Gregory’s armor both stained with both their blood.
“‘Course I did," Gregory said with a relieved laugh at hearing him speak again,
“what other knight can I trust to stitch me up better than any physician when
we find ourselves in these little messes?"
"I’d hardly call the Crusades a ‘little mess’," John said, and let himself sink
into Gregory’s arms.
***** Merlock *****
Chapter Summary
     Prompt: Sherlock/John, Merlock.
"They told me about your kind, the way you’d try to drag me down into the
depths with you." Sherlock just smiled his dangerous little smile and let the
tip of his silvery tale peek from the water as an unnecessary reminder, and
John climbed the rest of the way down the rigging to land with a splash into
the sea beside him. “Seems like I’m ready to follow, no matter what the
consequences."
***** Cabin Pressure Cooking AU *****
Chapter Summary
     Prompt: Douglas/Martin Cook AU.
"I have everything under control!" Martin shouted, in a panicked sort of way
that suggested anything but.
"Yes, what would I know about hastily throwing together a meal for three
hundred dignitaries, other than having done it before," Douglas drawled,
“seeing as I am simply a sous-chef and not the all-important chef de cuisine
like sir."
"Fine, fine we’ll do it your way, just—just don’t call me sir," Martin said,
then blushed at Douglas’s raised brow.
***** Keeping Quiet *****
Chapter Summary
     Prompt: Johncroft, "keeping quiet."
"Shhh," John whispered frantically, clapping his free hand—the one not rubbing
over Mycroft’s crotch through the tweed fabric of his trousers—over Mycroft’s
mouth to stifle a moan.
Mycroft gave him the briefest frown, obscured from view by John’s hand but felt
against his palm, before raising his eyebrow and drawing his tongue over John’s
fingers to make him gasp and pull his hand away. “Honestly, John, if you doubt
that my brother instantly vacated Baker Street when he saw me ascend the stairs
to your bedroom, I’d have trouble believing that you know either of us half so
well as you think."
***** Student/Teacher Boarding School AU *****
Chapter Summary
     Prompt: johnlock, 19th century boarding school (students, teachers,
     teacher/student - up to you).
     Warning: implied underage.
"Holmes," John said warningly, “it’s really not proper for you to be in a
teacher’s quarters after dark—or any time, really."
"I know, sir, and I’m sorry"—he did not look or sound sorry at all to John,
standing there still in his uniform trousers and shirt with the collar
unfastened, biting at his bottom lip almost nervously—"but I had to come see
you. Don’t you ever tire of doing what is ‘proper’?" Holmes asked as he took
another step closer, ignoring John’s hand held up in warning.
***** Bakery AU *****
Chapter Summary
     Prompt: Sherlock is an artisan bread baker who seduces John by
     showing him how to bake bread. Think of the pottery wheel scene from
     Ghost but with bread dough. And kneading. So ... much ... kneading
     ...
     (This totally needs more than three sentences. Damn limitations.)
"It’s simple chemistry, John; you did study chemistry in your medical training,
correct, or have universities become completely inadequate?"
"Quit smirking and show me, then, you complete prat."
Sherlock did not stop smirking, but he did slide behind John and reach his arms
around, taking John’s hands in his own, and begin to knead the bread while
explaining, “Working it like this strengthens the gluten bonds produced when
water mixes with the glutenin and gliadin proteins in the flour, and evenly
distributes the yeast within."
***** Post-Apocalyptic AU *****
Chapter Summary
     Prompt: Irene & Molly, post-apocalyptic au.
It was dark when the knock came at the door—but then, it always was dark these
days, wasn’t it? Molly answered hesitantly, not sure of who to expect now that
most everyone she knew had—well, it was best not to dwell on it.
"I’m Irene," the woman explained, and the name was familiar even if her face
wasn’t, “I found you through Sherlock Holmes, he and John"—Molly caught her
breath to hear their names again after so long—"said once, long ago, that they
trusted you, and right now I need someone that I can trust."
***** Mystrade Chime AU *****
Chapter Summary
     Prompt: Mycroft/Lestrade, your Chimes_AU.
“My family invented that clock, you know,” Mycroft says, as though it’s the
most casual fact in the world.
“Just when I think I can’t be surprised by bloody Holmeses anymore, you go and
tell me a thing like that.” Greg grins, all playful exasperation, and kisses
him again with the thirteenth chime.
***** Mormor Primary School AU *****
Chapter Summary
     Prompt: MorMor. Primary school.
“It’s the very worst when a grown-up tells you ‘because’ like it’s some sort of
answer,” Jim says, swinging gently back and forth on the swing set, letting the
tips of his shoes dig angry trenches in the dirt. “Sometimes I wish I could
hold them down and rip the real answer out of them.”
“I’d help you—I could do that,” Sebastian answers in an instant.
***** Labyrinth Botanical Garden AU *****
Chapter Summary
     Prompt: Sarah x Jareth, Botanical Garden Shop.
“Everything I’ve done I’ve done for you,” Jareth mutters while staring
intently, trying to read some response.
“You are seriously saying that to a rose bush?” Sarah asks incredulously. “Is
that just the only line you have for the things you love?”
***** Library AU *****
Chapter Summary
     Prompt: Molrene library AU.
The reference desk at St Bart’s Medical Library is tucked—rather unhelpfully,
Molly thinks—in an alcove near the back of the stacks, so that the medical
students have to wander past nearly every book in the place before finding a
librarian to help them track down exactly what they’re looking for.
Consequentially, Molly spends most of her time looking at (muted) cat videos on
the internet, and finds herself squeaking with surprise when a well-put
together woman who hardly looks like a student leans over her desk to ask,
“Irene Adler—I understand you’re the one I should come to for help?"
When Molly nods, Irene’s smile turns playful—or predatory, Molly can’t decide
which—and she continues, “I need to do research on asphyxiation; just how much
time and force it takes to cause bruising, that sort of thing."
***** Mormor Omegaverse AU *****
Chapter Summary
     Prompt: Mormor, Omegaverse.
"You love this, don’t you, boss; giving up some of that control when your heat
hits you, on your hands and knees begging for it like any other ordinary
omega?"
"Sebastian," Jim growls, “let me be perfectly clear in saying that if you don’t
get over here and fuck me, I will hire a hitman when this is all done, I will
put him on you, and I will enjoy every moment of watching you scramble around
the world trying to avoid him until only one of you is left standing."
Sebastian laughs, full of dark amusement and the knowledge that it’s hardly a
threat—both of them would enjoy that scenario far too much—before he complies
and pushes into Jim in one rough, long slide.
***** Teenlock AU *****
Chapter Summary
     Prompt: Sherlock and John go swimming for the first time, and when
     John sees Sherlock with nothin' but shorts, he gets an erection and
     Sherlock calls him on it.
     Warning: implied underage.
It didn’t make sense: they’d been swimming together for a good twenty minutes
while everyone else was off on a hike, but it wasn’t until they’d gotten out of
the water to jump off the pier that John suddenly turned shy and started
keeping his distance instead of swimming close like he had been before—what
could cause a sudden change like—oh.
"What," Sherlock asked—despite knowing full well the answer, and the
consequences—as he pulled John close to him so that his hardness pressed
against Sherlock’s thigh, “is that?"
"What do you think?" John shot back, full of casual bravado despite the fact
that he was blushing furiously.
