****** In the Commander's Quarters ******
by hedduh
Summary
     Erwin has caught himself admiring the young man many times over the
     past few months, and more than a few times, he’s caught Armin looking
     back.
***** Chapter 1 *****
With this morning’s strategy meeting coming to an end, Erwin sits back at his
desk and asks, “Alright, any questions?” When none are forthcoming, he nods.
“Dismissed.”
As the room begins to clear, his eyes find themselves drawn to a certain blond
cadet. It’s certainly not a new occurrence. Erwin has caught himself admiring
the young man many times over the past few months, and more than a few times,
he’s caught Armin looking back. He thinks it’s probably time to clarify his
intentions. “Armin,” he calls, “a moment, please?”
Armin approaches his desk as the room empties.
“I’d like to ask you a question, Armin, but first I want to make it clear that
I’m not speaking to you as your Commander right now, just a man on equal
footing as yourself.”
Armin blinks at the unexpected request. Curious, he nods his permission.
Erwin leans forward to clasp his hands together atop his desk. “I would very
much like to spend the night with you. Would you consent to visit my quarters
tonight?”
Armin’s eyes widen and a blush rises to his cheeks. He looks down bashfully and
chews his bottom lip. “I…”
“I don’t want to pressure you, Armin,” he says, straightening in his chair.
“Take some time to think about it. If you decide you’d like to join me, I’ll be
here after evening meal. If you choose not to, I’ll understand.”
“Okay,” he answers, nodding to himself. “I’ll consider it.”
“Thank you.”
Armin gives him a small smile and turns to leave. He’s about to close the door
behind him when Erwin calls his name again.
“Yes?” he asks, turning to lock eyes with Erwin again.
“There’s no time limit on this, so take as long as you need. It doesn’t have to
be tonight.”
Armin nods and backs out into the hallway with a soft “Thank you… Erwin.”
before the door closes.
-
Erwin’s at his desk, his jacket cast off but still partially in uniform aside
from the belts missing from his top half, sleeves rolled up and top two buttons
undone. He’s finishing some paperwork before bed when there’s a soft knock on
his door. “Come!”
He flicks his eyes toward the door to see Armin slipping inside. He’s wearing
loose fitting sleep clothes and his hair looks slightly damp from the showers.
They regard each other silently for a moment until Erwin turns in his chair and
holds out his arm to beckon Armin closer.
Armin approaches, nervously gripping the bottom of his sleep shirt. He stops
when he’s directly in front of Erwin and Erwin’s large hand settles hot against
the small of his back.
“Will you sit with me while I finish this up? It will only take a few minutes.”
Armin nods and Erwin guides him forward between his spread legs to seat him on
Erwin’s left leg, Erwin’s hand never leaving his back.
Erwin pushes a soft kiss to his temple and begins rubbing a soothing pattern
against Armin’s back with his thumb, before turning his attention back to his
work. He feels Armin slowly begin to relax against him as Erwin scratches ink
over paper.
As Armin’s weight leans more against Erwin’s chest, it leaves Erwin’s hand free
to roam up and down his back and around to squeeze at his waist and hip. Armin
lets out a soft sigh and rests his head on Erwin’s shoulder, then nestles his
forehead into Erwin’s neck.
Erwin squeezes his outer thigh in response and finally signs his name at the
bottom of his document. He leaves it to dry for a moment while packing up his
ink and supplies one handed and storing them in a desk drawer. The documents
are then stored away in another.
Now freed from his task, Erwin lifts Armin’s face to his with a guiding finger
under his chin. He tilts his face and closes the short distance between them
until their lips are scant centimeters apart, where he pauses, looking into
Armin’s eyes. “May I?”
A whispered “Yes” is his response and Armin closes his eyes as Erwin presses
gently against his lips.
Armin’s lips are warm and soft, though his movements are a bit clumsy. Erwin
suspects he may be taking the boy’s first kiss, so he aims to make it as good
as possible. The arm wrapped around Armin’s back tightens to hold him close and
secure as his other hand slips up from Armin’s chin to cup the side of his face
to keep him in the perfect position. He continues the languorous presses of
lips against lips until Armin seems more confident in his actions.
He runs his tongue against Armin’s lower lip, sucking it lightly between his
own and releasing it to apply pressure to the seam of Armin’s lips, encouraging
them to part. When he licks inside, he finds Armin’s tongue already pressing
forward to meet his and in his surprise, Erwin lets out a pleased moan. Armin
inhales deeply and digs his fingers into Erwin’s shoulders as they lick into
each other’s mouths. Erwin pushes deeper, the feeling of their tongues sliding
seductively against each other in the hot cavern of Armin’s mouth has him
slowly hardening in his pants. His hands begin to roam Armin’s body more feely
and Erwin drinks in the soft sounds of Armin’s pleasure.
He slides his hands under Armin’s shirt to begin pushing the fabric upwards and
pulls away from Armin’s mouth just long enough to remove it completely before
continuing their kiss. He’s incredibly pleased to feel Armin’s fingers pulling
at the buttons of his own shirt seconds later. When Armin slips the final
button free, he leans back to push Erwin’s shirt open, licking his lips as his
eyes devour Erwin’s muscular chest. He runs his hands over Erwin’s pecs,
sucking on his bottom lip when the brush of his fingers over Erwin’s nipple
causes the muscles there to twitch and flex. He watches the play of muscles in
Erwin’s thick arms as he shrugs the shirt off completely.
Erwin takes this time to watch Armin, notes the slight flush on his cheeks, his
dilated pupils, his parted lips. The backs of his fingers brush up the side of
Armin’s cheek. “Beautiful.”
Armin’s eyes snap up and a deep flush appears on his face as he meets Erwin’s
gaze. Erwin smiles when he realizes he can feel the heat of it under his
fingers. “Stand up for me?”
Armin nods and slips forward to stand between Erwin’s legs once again. Erwin’s
large hands on his hips keep him close enough to Erwin that he barely has to
lean forward to initiate another kiss. Armin’s hands settle on Erwin’s
shoulders before sliding down his arms, marveling at the size of them as Erwin
unfastens Armin’s pants and pushes them down his slim hips along with his
underwear. Erwin waits for Armin to step out of them before sliding one arm
around and under Armin’s ass and the other up his back to grip at his shoulder,
standing and lifting Armin to deposit him on the desk.
Armin makes a small noise of complaint when his bare skin touches the cool
wooden surface, but is distracted quickly enough when Erwin sucks one last time
on his tongue and starts trailing wet, open-mouthed kisses down to his neck.
Armin’s hands slide into Erwin’s hair and he tilts his head to the side when
Erwin begins sucking and nibbling at his neck. He’s breathing heavily through
his mouth now, making soft pleasurable little noises when Erwin finds an
especially sensitive spot.
Erwin continues his exploration of heated skin, kissing his way down Armin’s
chest, stopping to tease his pretty pink nipples with lips, tongue and teeth.
He enjoys the way Armin wiggles and the hitches of breath when he sucks hard at
the tender little nubs.
Armin tugs lightly at Erwin’s hair when the stimulation gets to be a little too
much, and Erwin leaves off to nip soft bites down the skin of his abdomen on
his way down to Armin’s hip.
Erwin lowers himself back down into his chair and licks at the crease of
Armin’s thigh and Armin leans back on his elbows to watch Erwin’s head moving
between his legs. Erwin grips the inside of Armin’s thighs and pushes them
wider as he noses over to run his tongue over Armin’s balls and gently suck
them into his mouth. He rolls them on his tongue as Armin keens and his cock
gives a violent twitch. He releases them to take Armin’s cock into his mouth
and only manages to bob his head a few times before Armin cries out and cums
hot against his tongue.
Erwin swallows around him and runs his tongue along the length of him to clean
up a bit before he lets Armin slip from his mouth. He runs his hands up and
down Armin’s legs while he recovers, pressing light kisses to his thighs and
wherever else he can reach.
As Armin recovers, his muscles tense and he pulls his had up to his mouth.
“I’m…”
Erwin turns his attention to Armin’s face and rubs his lightly stubbled cheek
against the inside of his thigh. “What is it?”
Armin shivers a bit at the sensation and tries to elaborate. “I’m sor… I,” he
waves his hand in Erwin’s direction, “in your mouth.”
Erwin smiles and nuzzles a bit harder. “That’s nothing to apologize for. I
expected that.” He moves to suck a mark near the crease of his thigh. “I wanted
that,” he growls. “You were so good, Armin. So good for me.”
Armin shivers and reaches out for Erwin, not quite able to make himself sit up
yet. Erwin stands and leans forward to embrace him, planting soft kisses along
his jaw. When he reaches Armin’s mouth, Armin doesn’t hesitate to kiss him
deeply, tasting himself on Erwin’s tongue.
Armin lets out a breathy moan when he feels Erwin’s hips press against him, his
cock hard and straining against the pants he’s still wearing. He wraps his legs
around Erwin and thrusts against him, his own flesh beginning to harden again.
Erwin pulls his mouth away with a curse and presses his temple to the side of
Armin’s head. “May I take you to bed?” he breathes into his ear, licking the
shell of it and sucking lightly at his lobe.
“Yes,” he moans, “yes, please…” His legs unhook from Erwin’s hips as the man
stands and Armin is scooped up into Erwin’s arms and carried toward his
bedroom.

Chapter Notes
See the end of the chapter for notes
Erwin kicks the door closed behind him before depositing Armin on the bed. When
he has him situated to his liking, Erwin crawls over him, knees planted on
either side of Armin’s legs, and resumes kissing his puffy lips. He plants one
arm on the bed to support himself while his free hand tangles in Armin’s hair.
Armin’s hands grip Erwin’s jaw as he opens his mouth wide to lick and suck at
his tongue. Deciding he hasn’t felt nearly enough of Erwin’s bare skin, he
trails his hands down Erwin’s chest and abs, making a sound of displeasure when
his fingers meet the waistband of the pants Erwin still wears.
He fumbles blindly at the front closure until he gets it unfastened and slips
his hand through the opening. He grips Erwin lightly through his underwear and
Erwin groans and bucks his hips forward. Armin gasps in response and strokes
over the hard length of him, only faintly registering his own hips straining up
off the bed.
Frustrated by the limited space he has to work with, Armin withdraws his hand
and starts pushing at the waist of Erwin’s pants. “Off,” he huffs, “take them
off.”
Erwin hums his assent and reluctantly stands to shuck the rest of his clothes,
smirking a bit when he sees Armin’s cheeks redden again as he gets his first
look at Erwin’s cock. Climbing back onto the mattress, he takes Armin’s ankles
in his hands and pulls his legs open far enough to kneel between them, running
his big hands up the length of Armin’s legs. Erwin leans forward to mouth at
his pretty pink nipples and suck a trail of kisses up Armin’s neck to his ear.
“So pretty,” he rasps, biting the sensitive skin behind Armin’s ear. “I want to
touch every inch of you.”
Armin moans as heat pools in his gut and he turns his head to catch Erwin’s
lips again. He pulls at Erwin’s shoulders, wanting to feel the weight of his
body pressing Armin into the bed.
Erwin complies, pinning him down and ravaging his mouth until Armin is
breathless and panting for air. “Will you roll over for me, sweet boy?”
Armin’s cheeks color, but he nods in response and Erwin helps him maneuver onto
his stomach while Erwin keeps his place on the bed. Once he’s settled again, he
feels the steady pressure of Erwin’s hands smoothing up his back, spanning
almost the entire width of it.
Erwin sucks and bites at the back of his neck, trailing wet open-mouthed kisses
down his spine as he shuffles further down the bed. His large hands grab and
squeeze at Armin’s ass cheeks, planting kisses there too.
Armin’s hands clench in the sheets as Erwin spreads his cheeks and presses his
tongue flat against his puckered opening. He twitches and mewls as Erwin
lavishes attention there, licking and sucking at the crinkled skin.
Erwin works the ring of muscle, slow and insistent until it opens on the tip of
his tongue. He works his tongue inside slowly, pushing straight in and curling
on the way out, sucking lightly before pushing in again, deeper. Armin keens
above him, his hands scrabbling at the pillows, mouth open and panting between
moans.
By the time Erwin manages to work his entire tongue into his ass, Armin is
rutting his hips jerkily down into the mattress and gasping Erwin’s name almost
continuously. Not wanting this to end prematurely, Erwin pulls back and grasps
Armin’s hips to tug them up off the bed. Armin whines in protest, mostly lost
in his pleasure with his face pressed to the pillow.
“Shh…” Erwin whispers to him as he bends forward, pressing against Armin’s back
to kiss his shoulders. “Let me take care of you, hmm?” He wraps his body around
Armin’s, his thick cock pressing into the cleft of Armin’s ass. He grinds
against the spit slicked heat of him and licks into Armin’s ear. “I want to
make you feel good.”
Armin moans and nods his head as best he can against the pillow. “Erwin,” he
rasps, “Please, please, please…”
Erwin’s hand snakes down to Armin’s ass again, his thumb pulling him open
gently. “May I kiss you some more, sweet boy?”
“Yes,” he breathes, “Erwin, please.” He presses his hips back against Erwin,
trying to urge him on.
“Good boy,” Erwin practically growls, making him shiver. “Such a good boy for
me,” he speaks against his back, kissing his way back down Armin’s spine. He
takes a moment to admire his work so far, pulling at the pink rim to see how
far he can comfortably open it. Deciding he’s happy with his progress, Erwin
gathers spit in his mouth before bending to thrust his tongue inside once
again.
He wants this to last forever, but his own cock throbs, hanging heavy and
neglected between his legs. Erwin wraps a hand around himself, meaning only to
give himself a few slow strokes to tide him over, but with Armin moaning and
clenching around his tongue, he finds himself dangerously close to orgasm. He
gives a firm squeeze to the base of his cock and holds it, buying himself a
little more time.
Armin loses all sense of time, the slick, velvety heat of Erwin’s tongue
fucking into him for what seems like hours. Days. Literal fucking years of
bliss. His throat feels dry and raspy from his near constant moans and
whimpers. His neck is starting to cramp from the way he’s been pressed into the
pillow, but when he shifts his head to relieve the pressure, he looks down
between his legs and catches sight of Erwin fisting his own cock.
The reaction is almost immediate. His balls tighten and he cries out, “Erwin!
Erwin I’m…” His voice cuts off as he’s flipped onto his back, Erwin diving in
to swallow his cock as he yells, pulsing his release once again into the heat
of Erwin’s mouth. His fingers dig into Erwin’s scalp, tugging his hair as he
thrusts weakly through the end of his orgasm, eyes clenched shut and mouth
open, his breath caught in his lungs as the pleasure overwhelms him.
Erwin swallows everything he’s given and then kneels between Armin’s legs,
stroking himself while admiring the state the boy is in. His flushed sweaty
skin, his blown pupils, his harsh breathing, his cock slowly softening against
his belly. He’s watching Erwin’s fist as he works it swiftly over his shaft,
squeezing at the head of his cock every few strokes. Armin stares and licks his
lips and the thought of his mouth on Erwin’s cock is what ultimately does him
in. He thrusts hard into his hand and comes over Armin’s torso, cock and balls,
muscles clenched and breathing hard. After one last pull, Erwin leans forward
with his clean hand planted on the bed to pepper Armin’s face with kisses while
lightly rubbing his cum into Armin’s belly with his free hand. “You look so
good like this, Sweetheart. Flushed and sated and mine,” he purrs.
Armin kisses him then, wet and lazy and content. He blinks slowly at Erwin when
he pulls away to wet a rag in the washbasin and nearly starts to drift off
while Erwin cleans them both. He nestles into Erwin’s chest afterward, Erwin’s
hands rubbing a soothing pattern into his back and whispering sweet words to
him as he falls asleep.
