Summary
     They have all their classes together. No one knows they're together
     except a few of their friends. One day, there's an in-class movie and
     Merlin and Arthur sit in the back and jerk each other off.
Notes
     Written for the tenth Kinkme-Merlin!
Arthur didn't always like Merlin. They met in fifth grade, when Merlin was
jumped up from fourth, told to join his new class and sit next to Arthur. For a
genius he was pretty darn stupid, Arthur decided, and just for that he poured
Merlin's entire pencil case out of the window. Merlin wasn't angry. He wasn't
shouting, or crying (like Arthur secretly hoped.) He just stood up from where
he was sitting by his desk, walked over to Arthur who stood by the window. His
eyes were big and blue, and he was very serious for a ten year old.
"That was very mean, prat." He calmly said, and then left the classroom with
his now empty pencil case to retrieve all of his pens and pencils. 
After that, Arthur tried everything in his power, but couldn't make Merlin
subdued, quiet and humiliated. He'd pour ants down his pants in gym class, trip
him on his way to the front of the class during math, he even secretly
supervised from afar when the members of his soccer little league held Merlin
upside down with his head in the toilet. After each incident, Merlin would just
back Arthur up and with his serious, blazing blue eyes, accuse him of being a
prat, a tosser and a bully, and tell him to back the hell off. 
Because of that, it was only natural they became best friends once they both
started junior high. 
They obviously sat together in each of their classes, to the horror of their
teachers. In a vast attempt to separate them, their teachers tried to catch
them off their guard with questions they were meant to get wrong, consequently
leading to one of them moving from their usual table at the end of the
classroom. The only problem, of course, was that Merlin was slightly a genius
and Arthur was so charming and quick on his feet he could make up an answer to
every question thrown at him. Or so they thought, until the first teacher-
parent meeting.
Being at the mercy of their teachers sucked to say the least, plus the fact
that Merlin started taking advanced everything in eighth grade, and they
stopped having every class together. It all changed when they started high
school. Picking up classes meant they could build their schedule around
Merlin's advanced chemistry, math, English and history. Arthur really didn't
care what classes he took, as long as he could sit next to Merlin.
They took every class together with the exception of PE (Merlin had advanced
English). Arthur even agreed to go to advanced History with Merlin only so he
could watch him make notes of every word the teacher said.
It was obvious, of course, that once Arthur started liking Merlin, he also fell
in love with him. But how could he not? Merlin was very graceful, in his stupid
clumsy way. He did advanced crossword puzzles that Arthur took pride in helping
him with by making up answers that were as obscene and filthy as possible. He
read history books for fun, and could quote the Return of the Jedi from top to
bottom. He had stupidly big ears that he tucked his black hair behind, and
there was always a curl peeking from the bottom of Merlin's lobe. But the
greatest this about Merlin wasn't that he always read three books
simultaneously, or that he could live on Mars bars and M&Ms with peanuts. The
greatest thing about Merlin was that he loved Arthur back.
Arthur had never kept a secret so big in his life. Homosexuality, he knew,
would not bode well with Uther Pendragon. Or with his soccer team, for that
matter. And it was always hard to get some alone time, no pun intended, with
Gwen and Morgana loitering around and making kissy noises at them. Merlin was
too much of a kind soul, so he always invited the girls to watch movies with
them and Arthur would not grope Merlin in front of his older sister. No sir.
That, of course, was another plus of having every class together. That, and the
fact that Arthur was a sex pervert, according to Merlin.
And despite his righteous blabber, Merlin didn't mind holding hands with Arthur
while he took History notes, and he didn't mind Arthur whispering filthy
descriptions of what he'll do to him while he'll help Merlin 'study' for a math
test. He certainly didn't mind keeping his hand on Arthur's knee the entire
hour of homeroom, completely ignoring how desperately hard Arthur was the
entire time.
But that particular morning, it started as a sort of a prank. Merlin came to
Arthur's for breakfast and a ride to school, and they skipped breakfast in
favor of a quickie in Arthur's room, except that Merlin didn't want to be late,
so he made Arthur stop even though he was panting as he re-arranged his
clothes. Arthur was very, very frustrated and Morgana's teasing when they got
to the kitchen was not helping. 
That was why the in-class movie during biology was a complete blessing. Arthur
practically jumped up and down when the blinds were drawn down the windows and
the lights were turned off. The only light came from a tiny TV at the front of
the classroom. Their teacher, Mrs Appelbaum, was grading tests to the light of
her cellphone, and everyone else started edging their seats closer to the
screen in order the view better.

"You want to get a closer look?" Arthur asked, hoping that the answer would be
negative.
"Nah," Merlin muttered. "I've seen it on the Discovery channel a month ago.
I'll just take notes."
"Good." Arthur whispered back, and sat back for a moment, watching Merlin flip
through his notebook for a blank page, and starting to write furiously.
"Merlin." Arthur whispered when the movie actually started, and a woman was
seen on the screen, in front of a big hospital. "Merlin."
"What?" Merlin whispered back, annoyed, and glanced at Arthur sideways, hand
still writing.
"Merlin." Arthur repeated, half to gain Merlin's attention, and half to annoy
him. "I wish we weren't disturbed this morning."
Even in the dim light he could see Merlin's lips twitch, and he knew he was
blushing. "Well, we need to get our education. Which you're preventing right
now. Watch the movie."
"But I don't care about the stupid movie." Arthur whispered, and after a quick
glance around to see nobody was looking, he leaned in to lick behind Merlin's
ear. He was smart enough to jump right back because Merlin's sharp intake of
air got a few heads turning.
"What are you doing?" Merlin muttered through clenched teeth when they all
turned around again. Arthur noted he was so shocked he stopped writing. "We're
in public."
"I'm not doing anything." He whispered very quietly and very close to Merlin's
ear, and placed a hand on his thigh. He could feel Merlin freeze under the
touch, and he turned to look at him with glinting blue eyes.
Arthur mouthed an innocent "What?" and with his other hand gestured towards
Merlin's notebook, in a movement that said 'go on, keep writing.'
Two minutes was all Arthur could take, staying still, and he started to softly
trail his hand up and down Merlin's thigh, each time edging higher and higher.
Merlin practically jumped from under his hand and whirled around so fast his
Arthur was surprised his chair didn't fall over.
"Stop it, you sex-starved maniac," Merlin's stare was so severe Arthur's head
could have exploded. "We'll get expelled." 
"I don't see you objecting much." Arthur whispered, and palmed the obvious
bulge that was forming in Merlin's jeans. 
Merlin made a soft sighing sound of surprise and went slightly limp as his
erection grew under Arthur's eager fingers. Arthur managed to open his button
and unzip his fly before Merlin seemingly came back into life, and though
slightly choked, managed to mutter "If I'm going down, you're going down with
me."
The next thing Arthur felt was Merlin's hand, the one not still holding the
pencil, slipping past the rubber waistband of his soccer shorts and into his
boxers, to finger his already throbbing erection. "My, my…" He muttered low and
hoarse. "You are a perv, Pendragon."
"Shhh." Arthur scolded him silently. "Watch the stupid movie." 
He quickly realized it's very, very hard to concentrate on the movie. Merlin's
fingers were cold and soft as he wrapped his hand around Arthur's hard cock.
Arthur fought back a moan with the idea of his entire class and half of his
soccer team that took it, and how he'll be beaten to death if they turned
around now. Actually, the idea of Merlin jerking him off while Leon and Cedric
just a few meters away, made Arthur's hips jerk a little and his chair creaked.
Both he and Merlin froze, but after a second of silence, Merlin resumed his
eager movements. Arthur decided he was not going to play fair. He squeezed a
little harder, drawing his fist from the base of the shaft to the head, where
he enclosed it in his hand for a moment before drawing a finger softly down the
underside.
Merlin gasped and his hips started thrusting softly, despite himself. He shot
Arthur a nasty look and ran his hands town to fondle Arthur's balls, just to
feel him squirm as well. Arthur's hand was already slick from pre-come, and his
other hand was fisted and in his mouth to stop from groaning. Merlin was just
as bad, eyes squeezed shot, teeth almost cutting his bottom lip and his hand
left the pencil to grasp the edge of his seat.
"If we weren't in the middle of class right now, I'd be on my knees, sucking
you off." Arthur whispered to him, watching Merlin's hips stutter and his eyes
squeeze tighter. "I'd lick every part of you, actually. I'll swallow every bit.
Merlin's eye cracked open and he started pumping Arthur quicker. Arthur felt
his breath leave him and for a moment, he could not speak or breathe, just
slide further towards the edge of the sit and thrust quietly into Merlin's
fist. When Merlin whispered back, it was so quiet that he had to repeat in so
Arthur would hear, and when he did, Arthur nearly came because he asked "And
then what?"
Arthur panted silently for a moment before leaning in again and saying "And
then I'd sit down in Mrs. Applebaum's chair, and I'll pull you into my lap. And
I-I'll kiss your neck, right here," He stopped to lean in and kiss just under
Merlin's jaw "As I start to prep you up with my fingers."
He could feel Merlin's hand pumping faster and faster, and he wanted to tell
him to slow down because he won't last much longer like that, but he couldn't
help mirroring the needy, hasty rhythm. Merlin was practically writhing in his
chair, his shoulders trembling, and his teeth left his bottom lip only so he
could whisper "God, Arthur" and "Go on."
And Arthur did. "And when I've got three fingers in you I'd started fucking you
slowly with them. You'll have your arms around my neck and your legs wrapped
around my waist." He stopped to breathe for a second as heat started building
deep in his stomach. He could hear murmurs from his other classmates because
really, in class movies weren't that interesting, but no one was busy looking
at Merlin and him. "And then I'd pull out, and I'll use both hands to lift you
up as I thrust into you. And you'll be opened just right for my, with your
hands in my hair, tugging, and oh, god, Merlin, I-"
And he could hear Merlin's soft sighs of "oh god, oh god, Arthur, A-Arthur" and
he just had to keep going. Their hands were now losing the rhythm, just pumping
hard and slick with pre-come.
"Merlin, Merlin…" Arthur mumbled, "I'll lift you up with both hands just to
pull you back down so hard, and I'll be buried so deep inside of you, god,
Merlin, I- I-, Merlin, I'll shove so hard into you but you'll be pushing back
down, clinging to me, taking m-"
And it was lucky that Merlin came, groaning silently, and taking Arthur with
him, gasping into his fist. It was lucky because they had just enough time to
push everything into place. Merlin zipped up his pants with one hand, licking
his other hand clean. His eyes were burning into Arthur's, and Arthur nearly
got hard again. Arthur wiped his hand on the bottom of his desk and had just
enough time to kiss Merlin's lips quickly before the lights came back of and
everyone started shuffling to their feet. Arthur didn't think he could move, so
he and Merlin sat there, looking at each other, until everyone left the
classroom.
And Arthur couldn't help but grin and agree when Merlin said "Wanna skip
Chemistry?" because he figured, they already got that going on.
