Notes
     This occurs after my fic "Submit", but can be read as a standalone.

Jean was having some trouble concentrating on his 3DMG training, and not just
because his ass hurt like a bitch from the previous night, although that did
make him wince every now and then.  No, what was causing him to zone out and
barely avoid running into the other cadets was Eren.
When Eren had walked into the mess hall that morning, Jean had choked on his
hash browns.  Eren had three huge reddish-purple bruises on his neck, and he
had made absolutely no attempt to hide them.  Before Jean turned to Marco (who
was freaking out and thinking that Jean was going to choke and die) Eren and
Jean locked eyes, and Eren sent Jean the tiniest of smirks.  Jean’s face heated
even more (because, you know, he was choking) and with the help of Marco, was
able to finally swallow and regain some composure.  But his face remained pink
throughout his whole breakfast, thinking about what he and Eren had done the
night before. 
If Jean had been whipped before, he was completely gone now.  During the
morning exercises, Jean’s eyes would unconsciously roam over to Eren, and
sometimes Eren would glance over and they would share a couple seconds of eye
contact and just that was enough for Jean to remember the previous night and
how Eren looked while he was pounding into Jean and just how fucking sexy he
was – and then Jean would about face and smack himself mentally because he
really should be paying more attention and stop being such a twitter pated
idiot.  They had fucked.  So what? It’s not like they were in a real
relationship or declared their undying love for each other – ew, no.  It was
just sex.  Jean should really try to forget about it for now – or at least not
think about it when he was supposed to be paying attention during a lecture or
not running into people during 3DMG training. 
Besides, it had only happened last night! Eren had said he wanted to go again,
but he almost certainly didn’t mean the next day.  No matter how horny Jean was
(and he was pretty horny) he shouldn’t act so needy.  It was clingy and weird
and just plain uncool. 
Jean brought himself back to the present.  Luckily, even when he was completely
out of focus during training, he was still pretty good on the 3DMG.  As such,
he was one of the ten trainees who had earned the highest scores on the
exercise, and as such, were dismissed to dinner a half hour early and didn’t
have to participate in the end of the day conditioning, or as it was more
commonly called, Hell. 
A bunch of the trainees that had finished in the top ten filed in behind Sasha,
who was probably going to the kitchen to steal some food.  Jean, on the other
hand, was heading back to the dorms.  He always headed there first, as he hated
the straps of the 3DMG and how they dug into the bruises they gave him.  Jean
decided to take a shortcut through the lecture building.  Jean walked down the
hallway, deciding to undo the chest strap while he walked, letting the straps
slide off his shoulders and hang off his waist. 
“Are you seriously undressing in public?”
Jean’s stomach did a flip at that voice.  Eren. Jean turned to face Eren, who
was standing a few yards away from him, legs shoulder length apart and arms
crossed, grinning at Jean.  Jean bit his lip and then smirked at him. 
“Maybe,” was the only comeback Jean could come up with because his heart was
pumping like crazy and holy crap was Eren just as eager as he was?
“C’mere,” Eren tilted his chin upwards.  Jean raised an eyebrow.  What was Eren
planning on doing? They were in public, which Jean wouldn’t be completely
against, but it was the daytime, and there were people who used this building
even when the 104th wasn’t. 
Jean stepped towards Eren anyway, closing the distance with four steps.  Jean
opened his mouth to ask Eren just what the fuck he was planning with that
mischievous smirk, but before Jean could say anything Eren shoved him through a
door.  It slammed open and Jean crashed into the back wall.
“Dammit, Jaeger!” he yelled.  He was in a broom closet.  He could tell because
his foot was in a fucking mop bucket and there were around four brooms that
fell on him.  He was lucky there weren’t shelves on that wall or else they
probably would have been broken, that’s how hard Jean hit the wall.
“Why the fuck do I even find you attractive,” Jean muttered, shoving the brooms
off and wiggling his foot out of the bucket.  Eren laughed at him and closed
the door behind them, then pulled a string that turned on the light bulb
hanging from the ceiling.
“Sorry,” Eren smirked.  Jean glared at him.
“No you’re not,” Jean scoffed, pouting and crossing his arms.
“Hmm… Then why don’t you let me make it up to you?” Jean glanced back at Eren,
who knelt down on the ground.  Jean’s eye bulged as Eren began taking off the
piece of leather Jean wore around his hips.
“Eren – you don’t have to do that...” Jean trailed off.  He wanted Eren to do
it.  He really fucking wanted Eren to do that.  Fuck, he hadn’t even fantasized
about how amazing it would be for Eren to blow him; just seeing Eren kneeling
there undoing the straps around his hips was turning him on.
“I want to Jean, I really do,” Eren said, fiddling with the clasps on the
belts, which were insanely difficult to get off.  “I’ve seen the way you’re
looking at me during training-“
“Yeah, you and those fucking hickeys.  What the hell were you thinking?” Jean
asked.  Eren smiled, still working with Jean’s pants, finally undoing all the
straps and stripping them away. He was that much closer to his prize.
“I was thinking,” Eren said, “that last night was fucking incredible and I
wanted to repeat it as soon as humanly possible.”
Jean bit his lip.  Eren felt the same way as he did! So he wasn’t being overly
clingy after all…
“Never mind that,” Eren said, unzipping Jean’s pants.  He pulled his pants and
underwear down in one motion, freeing Jean’s cock, which was already half-
hard.  Jean’s breath hitched as the cool air hit his dick, and he gasped again
when Eren’s hands grabbed his thighs.  His hands were cold and rough with
callouses from all the training.
“Hmm, excited already?” Eren teased, grinning as he tilted his head up to look
at Jean.  Jean was biting his lip and had one hand near his face so if he
needed to scream he would have something to bite on.  Jean tried to control his
breathing when Eren looked up at him like that, like Jean already being half-
hard was the most endearing thing.  He couldn’t take it.
Eren turned his attention back to Jean, blowing lightly on the tip of his cock,
and making it twitch, still not completely hard.  Eren kissed the tip lightly,
a simple and chaste kiss that would have been more suited for kissing a loved
one the cheek than teasing Jean.  Jean was confused once again by the way Eren
seemed to be entranced by his dick.  It was like last night, the way that Eren
had so skillfully moved his hand over Jean, knowing just how to twist and
squeeze.  He almost worshipped Jean’s cock, and that was so new and strange to
him, and also undeniably, unbearably hot.
Eren decided to finally use his tongue, starting at the base and licking a wet
stripe all the way up to the tip.  Jean grunted, the hand that wasn’t near his
face curled and uncurled, Jean not sure if he should weave it in Eren’s hair or
not.  Eren tongued the slit and wrapped his lips around the tip of Jean’s cock,
and at that exact moment, he looked up from his work to lock gazes with Jean. 
Jean let out some sort of strangled whimper, clamping his hand over his mouth. 
Eren’s eyes were glazed over in lust and utter admiration, as if pleasuring
Jean gave himself immense pleasure as well.  But when he saw Jean clamp his
hand over his mouth he frowned and moved his mouth away from Jean, causing Jean
to whine audibly, even with the hand over his mouth.
“Jean, I want to hear you,” Eren stated simply, tugging Jean’s hand away from
his face and resting it on his neck.  Jean placed his other hand on Eren’s
head, lacing his finger through his hair.
“But what if people hear –“
“Jean, it’s almost dinnertime.  Nobody’s gonna be around here for a while,”
Eren said.  “Now promise me not to hold back.  I want to know how good you
feel,” Eren flashed that sexy smirk that Jean was beginning to love, and Jean
nodded.  Jean wasn’t really one to want to yell, especially during sex, but he
would try for Eren. 
“Good.” And with that, Eren took Jean’s cock into his mouth, making Jean groan
right off the bat at that unexpected stimulation.  Eren began to ease more into
his mouth, using his tongue to draw patterns on the underside while he set up a
rhythm – half an inch back, one in forward, and every other thrust he would
pull completely back, tonguing Jean’s slit so his eyes rolled in the back of
his hand and his fingernails dug into Eren’s skull.  The only thing keeping him
from thrusting furiously into Eren’s amazingly warm, soft mouth was the
vicelike grip he had on Jean’s hips.
After a couple rounds of this, Eren decided to switch it up.  He eased Jean’s
cock into his mouth as far as he could without choking and sucked, earning a
loud moan from Jean, who was breathing heavily, his head thrashing from side to
side.  He was sure he had probably pulled a clump of Eren’s hair out by now.
But the thing was, Eren didn’t stop there.  He kept taking Jean in, until his
whole dick was in Eren’s mouth.  He swallowed around Jean, which was the only
thing he could do to keep from gagging.  Jean went insane.
“Ah-Eren!” he cried, head tilted back in pleasure.  Eren could feel his thighs
twitching under his hands, and he was determined to make Jean scream his name
again.  He continued to swallow around Jean, who was slowly coming undone, his
hips thrusting involuntarily, his hair plastered to his forehead in sweat, and
he was making the most erotic noises – Eren might just come in his pants at
this rate.
Eren moved backwards, so Jean’s dick was no longer choking him, Jean whined as
Eren’s mouth all but left his dick, his tongue sliding over the tip before
their eyes met again, and Eren took Jean’s dick fully in his mouth in one swift
movement.  Jean howled and Eren swallowed, and then hummed, the vibration
coursing through Jean, who screamed.
“EREN!” he shouted, thrusting into his mouth, finally breaking the grip Eren
had on his hips.  Eren gagged as Jean thrust once, twice, into his mouth, and
Eren swallowed, feeling the hot, salty substance on his tongue.  He released
Jean’s dick and sat back on his heels, wiping his mouth with the back of his
hand, and smiling at Jean.
Jean was slumped against the wall, chest rising and falling rapidly, eyes
closed and legs twitching, barely able to support him. 
“Fuck,” he said, opening his eyes and finding Eren’s.  They smiled at each
other, and Jean laughed breathlessly as he let his legs give out and he slid to
the floor of the supply closet next to Eren.  He wrapped a hand behind Eren’s
neck and pulled him close, locking their lips in a short, but sweet kiss. 
“You-“ Jean struggled to string words together.  “You’re awesome.”
Eren laughed loudly, resting his forehead on Jean’s.
“’You’re awesome?’” he repeated.  Jean’s face flushed, and he smacked Eren in
the back of the head, who only laughed harder.
