Summary
          eruriren week
          Day 4: "Bruises And Bitemarks" / Day 6: “A New Hope”

     The night after the 57th expedition both Eren and Levi are searching
     for their Commander's support. Basically a smutty oneshot with a bit
     of characters study to celebrate the eruriren week.
Notes
     It's rushed and it's not revised how much I wanted but time at my
     disposal was little and in spite of all I had to join the eruriren
     week celebrations ('cause you know, the holy trinity is my main
     ship), so here you are.
     As usual sorry for the probable mistakes, but English is not my
     native language.

The silence in the castle, if possible, is deeper than usual. If before the
expedition there was enough space for all of them and more, now that the number
of the scouts is drastically reduced the empty rooms and the enveloping silence
echoing in the hallways is almost suffocating.
The 13th Commander of the Scouting Legion, Erwin Smith, is in his bed, sitting
pensive against the bed's headboard, reorganizing his thoughts about the
disastrous and just elapsed day. Sure he's been able to demonstrate his theory
about the existence of others titan shifters, but their failure in capturing
the female titan and the death of a good part of his men put him in a
precarious position against the higher ranks.
Right now, however, he's more concerned about the well being of two of his men
in particular. While about what already happened he doesn't have the power to
do anything, his thoughts bring him inevitably to Eren and Levi.
It's strange how in just over a month the young titan shifter has become so
important to him, and not because he's for real Humanity's Last Hope, even if
having created that nickname for the boy makes him very pleased with himself,
but because without even doing it on purpose he slipped under his skin.
Remembering his boiling anger and his determination have strengthened him and
made him unable to forget why he does what he does, why he have to fight and,
more importantly, find the truth to atone the sin of his father's death,
enhancing his purpose and making him able to bear the burden of his decisions
without regret to a brand new level, with the same determination he has seen in
those turquoise eyes. It's something for which he has become almost addicted,
something he repays encouraging the boy with warm smiles and kind words of
support and comprehension, 'cause the walls only know how much he's pressured
by his role and peculiar abilities and already kept in line by Levi not to need
more of this attitude even by his Commander.
And this brings back to his mind Levi: Erwin actually is waiting for him
tonight, he knows it's going to happen, he just have to wait till he's going to
be ready to give up. It all started after the expedition subsequent the death
of his two friends, when he found him in the common showers, in the dead of
night, sitting naked under the freezing spray of water, evidently unable to
bear with the death of always more comrades to which he became unintentionally
attached: that night the Commander didn't offered him words of comfort, he knew
him too well and he knew he would have rejected them, and so he offered him
what the smaller man wordlessly asked him for, jumping him with glacial anger,
demanding for rough comfort sex on the wet floor, without talking, without
crying, without even look into his eyes, only sinking his small candid and
perfect teeth in his broad shoulder to muffle his moans as the blond sank deep
inside of him, both of them expiating with the pain the death of their comrades
and at the same time celebrating with the pleasure the guilty and exhilarating
feeling of being still alive.
After that time it has become an habit, something they don't speak about so
often but that both of them know they're willing to do again and again, every
time it's needed, every time what they are going through threat to overwhelm
them, every time they cannot express with words the strict bond that tie them
but still want to remember that it exist. And this is why now Erwin is waiting
for him: today Levi's squad died because of him, because he ordered him to
wasting his time to refill his gas, because he suspected that something would
go wrong, as indeed happened, and so he's here now, ready to take
responsibility for those deaths as for dragging Levi into the Legion years ago,
forcing him to live this situation countless times.
When he hears someone knocking at his door, however, he's surprised. Levi
doesn't knock, he made a point in arriving always unannounced, a little habit
he has kept from his first period in the Legion, when he was still a beautiful
little and riotous stray cat still unable to understand how useful he could be
for humanity, how much Erwin was captivated by his perfect grace and how he,
and also the Legion, were not a threat but an opportunity for him.
"Come in." He simply answers with a loud tone, without leaving the bed, sure
his voice can reach the newcomer given that his quarters are not so huge and
the bedroom door is open. At this hour of the night he expects to be faced by
Hanji or maybe Mike and is not that they haven't see him shirtless and wearing
only his pajama pants, so he's for a moment weirded out when he sees a chestnut
brown mop of hair followed by a pair of turquoise eyes peeking shyly through
the door of his bedroom.
"Commander. Pardon me." Eren is obviously embarrassed by the unusual situation,
but despite this he straightens his back and his shoulders, saluting. "You told
me to come in so I thought I wasn't going to disturb you but you weren't in the
study, so..." He justifies himself, looking away from the older man, who is
still sitting on his bed half naked.
Once he woke up from his comatose sleep and remembered the events of the day
the boy started wandering through the almost empty castle, too afraid about
Levi's reaction to the apologies he felt he owes him to go in search of his
Captain, but still in need of comfort, or at least of someone to vent to. He
also didn't want to wake up Mikasa or Armin and burden them with his guilt and
dark thoughts about the futility of his existence and so he eventually decided
to go to the Commander's quarters as last resort, remembering how the man
always had for him an encouraging word or some nuggets of wisdom to soothe his
insecurities.
Seeing said men, however, half naked in his bed, suddenly had made him forget
his own problems and even the guilt he was feeling towards Petra and the rest
of the squad, abruptly flooded with memories of almost a couple of weeks
before. He was half lost in one of the most remote parts of the castle in
search of the cleaning products storage when he heard coming from a near
hallway a muffled moan: since he wasn't so naive as everyone seemed to think of
him of course he knew what kind of scene to expect from beyond the corner, but
he hadn't been able to resist the curiosity, internally hoping to find someone
of his graduate comrades in a compromising position to obtain material for a
playful blackmail and a bit of mockery. What he hadn't expected to face was a
trouserless Captain, legs fastened together around the chest of his partner and
wrists locked on top of his head by the iron grip of the Commander's hand, the
latter pounding mercilessly the smaller one into the wall. The sight had left
him mesmerized: to his own surprise he hadn't felt embarrassed neither jealous
of what was happening between them, but rather kind of aroused and a bit
disappointed by not being able to take part to that show of a perfect bond.
From that day he hadn't been able to watch his two superiors with the same
eyes. Until that time he worshipped them due to their reputation and their
skills, but also - after getting to know them a bit more - for different
reasons: if the Commander was always able to make him feel human and above all
cared for, sometimes with a simple word, others with an encouraging smile, the
Captain had become his anchor, the one with who he wasn't afraid to be a
monster, trusting him to accept him for all he was and stop him in case of
need. After that day, however, his feelings towards them had become confusing
and more than once he found himself in the middle of the night, locked in the
basement, touching himself to those memories, imagining to be still there,
watching them or maybe reaching them...
And so now he's here, staring at the floor, drowning in a new kind of guilt,
the one rising from the consciousness of having to mourn the dead but of not
being able to do so because of his shameless thoughts.
"It's ok Eren, you're not disturbing me." The voice of the Commander compels
him to look up at the other's face to find on it a sympathetic tiny smile
waiting for him. "I know it's been a tough day, but taking on you the entire
blame for what has happened will not make you feel better and also it wouldn't
be fair, so if you're here to tell me you're sorry I beg you not to do it
because I'm the one who should apologize to you."
"But sir--" The boy starts, before stopping his words seeing the older man
getting up from the bed and motioning to him to come closer.
"No buts. I'm the one who planned the expedition, I knew that what happened
would happen and I let it be because I needed to be certain you're not the only
shifter." His voice is low and calm and Eren can feel the bass of his tone
caressing him, soothing him, locking him in place like a dazzled animal while
the other man is closing the distance between them. "I'm the one who should
apologize to you for having used you as bait, but you did well, you've been
such a good boy."
And this is when the young titan shifter knows for sure he's screwed up,
utterly and beyond any repair. And not because he let himself hug his
Commander's bare chest in search of comfort, but because his praising words are
reminding him of his father and at the same time making him shiver because of
something he's quite sure he shouldn't feel towards a fatherly figure.
He let the blond gently caress his hair, reveling in the sensation of feeling
safe and cared for, when a sharp voice and its characteristic sarcastic tone
makes him jolt in surprise.
"What a lovely sight."
Levi closes the door behind him not failing to notice the meaningful smirk that
lingers barely visible on Erwin's lips: he had become quite sure that the blond
was up to something even before entering the room, when he heard the Commander
talking with Eren with the low voice he reserves for the most intimate moments
between them and that evanescent smirk only confirms his assumptions.
Both are by now aware for some time of the glances the boy launches to them
when he thinks he's not seen, they've even fantasized a couple of time about
letting him join their little rendezvous, because he's so transparent in his
emotions and desires to let them be sure that he could at least consider it,
but from there to think about actually doing it...
For sure the Captain wouldn't mind it, or rather, he would love it. His
relationship with Erwin has by now become something deeper than the initial
simple comfort sex from where they started: the Commander has become his safety
in the midst of the storm, the one taking the blame for his failures, saving
him in this way from the regrets and above all the only one seeming to
understand him all round, even in those aspects that didn't make him less
monstrous than Eren. For this very reason Erwin understood long before Levi
knew it how if he was the one able to make him not look behind him, to the
past, someone else was instead the one able to make him look to the future, to
make him hope. And being the great man he is, once figured this out, he told
his Captain he was ready to take a step back, leaving him free rein in courting
the boy. Pity that Levi wasn't able to accept his offer: despite yearning for
the green-eyed brat - probably as much as the Commander himself, even though
the blond would never admit it, not even to his trusted playmate - he wasn't
willing at all to let go what he already had.
But tonight maybe... maybe tonight is going to change everything, he thinks,
raising a hand to start undoing the buttons of his shirt, gaze fixed on Erwin,
deliberately ignoring the presence of the boy despite he's actually standing
between the two of them, currently struggling in embarrassment after having get
rid of the Commander's embrace.
"I… uhm… I suppose it's better for me to go."
The dark haired man can hear the younger one quickly approaching the door but
persists in ignoring him till he has get rid of his shirt and folded it.
"You can leave or you can stay and enjoy the show, I don't really care. The
door is not locked, so the choice is only up to you." He states with a bored
tone, starting to unfasten his trousers, still without directing his visual
attention to the boy.
"B-but sir!" The titan shifter voice is tinged by bewilderment and maybe by a
bit of dismay. "I'm not gonna intrude your relationship with the Commander!"
Levi hears Erwin chuckle almost silently, sign that with these words he also
had confirmation that Eren already knew about their private intercourses.
"You know Eren, Levi is here for some comfort exactly like you, only that for
him this has little to do with cuddling and much more with other activities."
The Commander explains with a soft calming voice, reaching the bed and sitting
on it, evidently deciding to play along Levi's line of conduct. "So your
Captain is sincere when he says he doesn't care for your presence, rather I
actually think he would enjoy it."
The boy let run his gaze between the two: they're now both ignoring him and
Erwin is helping the other one to get rid of his underwear, freeing his half
hard member just before he climbs him, straddling the older man and starting to
kiss him with feral voracity. Eren can feel his mouth drying and he knows he
shouldn't be here, he really shouldn't, but suddenly he's unable to remember
why, finding himself wondering which social rule requires him to leave when his
commanding officers granted him permission to actually live in first person
what he has only dared to fantasize about. Moreover what harm can he do just
looking, making himself small, silent and without disturbing them? It's a hard
decision, but with his own hardness starting to grow in his pajama he's really
by now unable to really think about leaving and so he let his back slide along
the door, sitting on the floor, sure his legs are going to fail him if the
scene before his eyes is going to endure.
The boy almost holds his breath, trying to remain unnoticed even if he's not
sure it's really necessary since the two on the bed seem completely taken by
themselves. The Commander had flip his position under the other one, lifting
him and laying him down on the mattress with such ease to make the titan
shifter shiver at the thought of the strength in those arms, and now he's
travelling his chest with his mouth, fiercely nibbling at his skin, descending
along a path that is clearly bringing him to the Captain's groin.
It's something beautiful and mesmerizing and Eren finds himself unable to look
away: it's not only the opportunity to see the objects of his more perverted
thoughts in such intimacy, but is also the look in the Commander's eyes, so
dark and tempting, and the low moans escaping from Levi's lips, sounds he never
thought he could hear coming from a man always so impassive, small wonders to
his ears making this so much better than any peak of his wildest imagination.
The moment when Erwin engulfs Levi's erection with his mouth, starting to work
at it with lewd sucking sounds, the titan shifter barely realizes that his hand
has descended along his chest to palm his junk, squeezing it in search of a bit
of relief. The boy's gaze is completely engrossed by his two superiors while he
follows with rapture Erwin coating his fingers with something he searched for
into his nightstand: he perfectly knows what's coming next and he can't avoid
to lean towards them, foretasting it.
When the Commander's first finger disappears inside Levi's body, Eren needs all
his will not to moan along the smaller man, his hand now trapped inside his
pajama pants, absent-mindedly caressing his hardness. The scene has something
intoxicating: seeing the Captain abandoning his usual composure, dropping his
glacial mask and letting himself drowning in his sensations is something he
thought he would never see, something he knows will not make him look at the
man in the same way again, but not with less respect than before, rather if
possible with more, because he finally understood more of his real character.
His uncontrolled stream of consciousness is however abruptly interrupted by
Erwin who, shifting his position, accidentally covers his sight with his broad
figure. Is a matter of moments before, without even realizing it, the boy
starts to crawl towards them, overwhelmed by the need to see more, to see
everything, even the smaller shade of emotion on the Captain's face, even
Erwin's minimal gesture, each of which make his upper half pulsate in such a
mesmerizing way.
It's only when he's barely at few inches from the Commander, a hand partially
lifted in the act of reaching his body, that he realizes that maybe, maybe the
older man covered his sight on purpose, because although up to this point he
had seemed completely unaware of the boy's presence, now he turns towards him
with clouded eyes and a faint sly smirk.
"Up for a taste?" He ask, moving a bit to the side, leaving for him enough free
space to be able to take place between him and the edge of the bed, where the
Captain is still legs spread, a couple of fingers buried inside him.
Eren puckers his lips, taken aback for a moment, but thinking how now it's
laughable to hold back above all because he still doesn't see the reason why.
All he can manage to do, however, is to shift his focus on Levi's face,
silently searching for consent, unable to express with words the turmoil of
feelings and sensations that are currently overwhelming him.
The raven-haired man is heavily breathing, but somehow he's able to control his
voice, shaping it in his usual deadpan tone. "Ever done it before?"
It's somewhat amusing how the boy's actions and his words don't match as he
says he did things before, shaking however his head in deny: it makes Levi
snort and Erwin smile with a shade of fondness while he hints with his head to
the lube still leaning open on the mattress near him.
"It's good you have yet to learn." The Commander starts with his low enveloping
and heating voice, following with his eyes the boy, now back to his determined
self, coating his own fingers and taking place between him and the Captain with
anticipation. "This means you have no bad habits from previous experiences."
"Come on! You two can chitchat later." Levi snarls, pushing his hips forward to
urge the fingers still inside him to do something. "Just put yours in with
Erwin's, he'll show you."
Eren cannot help but laugh, now finally relaxed, fulfilling the older man order
with a playful 'yessir'. The boy starts following his superior's rhythm,
letting slide his fingers in the tight heat of Levi's body in pace with those
of the other man, guided by suggestions whispered in his ear with a husky
voice. It doesn't take long before the enormity of the situation began to
overwhelm him: on one hand the Captain, who has started again to softly moan,
and this time because of him, because of his fingers, even if still leaded, and
on the other one the Commander, who is no longer limiting himself to suggest
him when crook his fingers, but who started to cover his neck with soft kisses,
still whispering between one and another, making him shiver with a need so
strong he starts to slightly tremble.
"Beautiful, isn't he?" Erwin asks to the young shifter, stopping the kisses to
hint at the man spread beneath them before returning to his previous
occupation. "You're doing so well." He resumes whispering, so tempting, this
time not only kissing but also nibbling at his skin. "You're such a good boy."
Eren simply nod, unable to form words or even thoughts that make sense. Being
praised this way, with such a lustful tone, is actually making him lose his
residual control and he doesn't even notice that Erwin's fingers have left his
alone until when he is startled by the Commander's now free hand, which takes
hold of the edge of his pajama pants and starts to pull them down. The boy
opens his mouth, furrowing a bit his brow, but the older man swiftly envelops
his cock with his other slick hand, cutting off any possible complaint and
pulling out from the boy a deep pleased groan.
"I need to lube you up if you want to take our Captain." The Commander
explains, still murmuring on his neck, starting to stroke him with painfully
slow movements, making the boy lose control over his body, moaning again and
stopping his fingers from pleasing the man beneath him.
"Holy fuck. I'm still here, you know?" Levi blurts out after a couple of
moments, clearly annoyed, kicking the blond to get his attention. "Less talk,
more fuck."
Erwin bursts into an amused laughter and then leaves the boy free from his
grasp. "You heard him Eren, he's all yours." He states before getting up from
his kneeling position beside the boy and crawling on the bed towards the raven-
haired man face. His lips stretch into a satisfied and cunning smile when Eren
makes his way into Levi's body, climbing on the smaller man, lifting his hips
for a better access and making him burst in a fulfilled moan, only partially
muffled by the Commander's kiss. "Tonight is for you my beautiful wildcat, tell
me what you want."
"Let me su--" Levi can only breath out those two words before moaning again,
arching his whole body to match the titan shifter's thrusts. "Shit. Right
there. Good boy."
Erwin chuckle again before practically straddling the Captain's head, facing
the green-eyed boy and raising an hand to claim his attention while between his
legs a greedy pair of lips starts to trail along his length before engulf it.
Levi's body arches beneath them, trying to remain easily accessible to both,
while the other two starts to share a heated kiss, Eren moaning inside Erwin's
mouth, clearly by now close to his end. Telling the truth also the Commander
feels like he's going not to last so long, Eren's addiction to their usual play
has in fact overheated him since the beginning and so when he feels Levi's body
start to tremble under him, evidently near to his end, he grabs the Captain's
cock at his base, squeezing it.
"Not yet my dear, be patient." He grunts before starting to actively pursue his
own pleasure, thrusting into the man's mouth, knowing that he's able to take
it.
Eren is the first one to let go, coming with a strangled cry, hands clawing
Levi's hips as to remain grounded in reality, and then Erwin frees from his
grasp the Captain's member, letting him release himself all over his stomach
while he's spilling inside the man's mouth, trembling with the effort not to
scream just like the boy who is meanwhile collapsed over Levi, barely
supporting himself on his arms not to crush him.
With a sigh of pleasant relief the three detangle their bodies before lying on
the bed, still groggy from the afterglow. Erwin, knowing this peace will not
last long because of Levi's need to clean up, takes the opportunity to make him
nestle against is chest, cuddling him with a lazy hand while he lays his other
one on Eren's shoulder, noticing how he has hinted at wanting to roll out of
the bed.
"You're more than welcome to stay, you know?" The Commander mumbles, trying to
fight the sleepiness that is overpowering him. "And I don't mean only tonight."
He adds, feeling the need to clarify the situation for the boy.
His words make him earn himself a grunt of agreement by Levi and a wide drowsy
and content smile by Eren, who decides to settle his back against the free side
of the Commander's chest with a loud yawn, using his arm as a pillow.
It takes only a few minutes before the boy starts muttering softly, clearly
half asleep. "Commander? Next time... next time could I top you?"
The bewildered silence that follows his words is broken by Levi, who barks out
a brief rasping laugh. "Good luck kiddo. It took me years to get there."
