Summary
     Erwin gets a late night visitor. He gets a little more than expected.
Notes
     I was watching Silent Hill when I came up with this. Somehow my mind
     went from Silent Hill to Playboy bunnies because I remembered
     something about Armin looking better as a bunny girl than any of the
     girls. I don’t know how or why, but apparently that is how my mind
     works, so you all get Playboy bunnies. Enjoy!
See the end of the work for more notes
A cautious knock on Erwin’s door close to midnight was the only warning he got.
Really, he should have known better, but he had automatically thought that
something was wrong. In hindsight, he really should have seen it coming.
There, in his doorway, stood Armin; cute little, unassuming Armin wearing…
Fuck, what the hell was he wearing?
Erwin inhaled a deep breath, counted to twenty very slowly, and exhaled. He was
a man who prided himself on his self-control. Dare he say, his self-control was
better than Levi’s. Actually, he knew it was better than Levi’s, and he took
pride in holding that fact over the shorter man’s head. Right now, though, that
same self-control was being thoroughly tested.
“U-um… Evening, Commander…” Armin muttered in a low voice, and Christ, he was
surprised the poor kid hadn’t passed out from all the blood rushing to his
face. Armin was redder than a cherry. The younger blond was fidgeting with his
hands in front of his waist, which drew Erwin’s eyes to places they should not
go, and his head was bowed, trying to hide his cherry-colored cheeks. Erwin
swallowed hard, gripping the doorframe firmly.
“Armin,” the Commander started. He was so proud that he managed to keep his
voice steady. Armin glanced nervously up at him through long lashes and blond
bangs, and fuck it if Erwin’s blood just redirected south. Outwardly, he
managed to keep his expression passive and calm. “What are you wearing?”
The embarrassed soldier before him fidgeted some more, baby blues darting this
way and that, anywhere but at the Commander. “I-it, um…” the poor blond trailed
off, licking his lips before starting over again. “E-Eren and I lost a bet… D-
do you like it?”
Erwin blinked stupidly down at the teen. What the hell kind of question was
that? Armin was looking anywhere but at him, wearing a dark blue sweater that
was far too big for his tiny frame, the sleeves falling over his hands and the
neck hanging quite low off of one shoulder, exposing far too much pale skin.
Unfortunately for the sweater, it had been cut off just below the chest,
revealing quite a bit of the younger’s toned stomach. He may be on the smaller
side, but Armin had undergone all the same rigorous training the rest of the
Legion had and his flat, faintly muscled abs proved it. All that beautiful,
pale skin was on display for Erwin’s eyes to feast, and it took sheer willpower
to keep them moving. Darkened blue orbs roved over thin hips and prominent
hipbones. His breath hitched at the little, boy shorts (did those even really
count as clothing?), the thin, black fabric leaving absolutely nothing to the
imagination and hugging Armin’s thin legs in the most perfect way. A pair of
stockings that matched the sweater almost perfectly encased the blonde’s
calves, coming to a stop just above the knees, leaving his creamy thighs free
for Erwin’s viewing pleasure. And damn, what a pleasure it was.
To top off the whole ensemble, a pair of bunny ears rested on top of Armin’s
head, one ear drooping lazily. Erwin briefly wondered where the hell those
could have come from. He then decided that he couldn’t really give a shit.
The Commander continued to ravish the mortified teenager with his eyes, hardly
caring if he was making Armin even more uncomfortable. He was brought out of
his musings by the smaller blonde’s voice.
“Uh, s-sir?” the younger muttered. His voice was quivering and somewhere deep
down Erwin felt bad for him.
Erwin cleared his throat in an effort to bring his thoughts back under control.
“What kind of bet was it that made you have to wear… this?” He waved his hand
over the teen, so proud his voice remained steady, if a little on the husky
side.
“I’m n-not exactly sure myself…” Armin muttered. “It was between Jean and Eren.
Something about a race and if Eren lost then he and I had to… dress up s-sexily
for you and Corporal Levi…” The kid still refused to look up, wringing his
hands in apprehension.
The older blond casually leant against the doorframe, a disbelieving chuckle
escaping him. “Eren lost on purpose, didn’t he?” he asked, crossing his arms.
Armin idly pulled at the hem of his shorts, accidentally pulling them down
further and exposing his v-line. “I-I think so, s-sir…”
Sighing wearily, Erwin rubbed his temple, blue eyes falling closed. “Levi’s
never going to let me hear the end of this…” he muttered, mostly to himself.
Armin finally peeked up from under golden bangs.
“C-Commander?” he asked softly. Erwin gazed down at him once more. Armin
absently dug his shoeless toes into the cold floor and Erwin’s mind all but
screamed ‘adorable.’
Before the younger could say anything else, Erwin opened his door wider,
inviting Armin in. “Let me get you a blanket or something,” he said, his
gentleman side momentarily kicking in. “You look cold.”
Armin hesitated a moment before nodding, slowly striding past his superior,
hips swaying with every step he took. Erwin tried not to look, tried so very
hard, but his eyes betrayed him, falling to Armin’s cute little bum. He choked.
Well, the ears made a bit more sense now.
Attached to the shorts and perched right over Armin’s cute (grabable, perfect,
tight) ass was a little ball of cotton designed to imitate a rabbit’s tail and
the little tuft swayed with every step Armin took. Erwin swallowed heavily just
as he felt that self-control he prided himself on completely snap. The teen
stopped in the middle of the room, glancing around absently as Erwin came up
behind him. He jumped as the Commander rested his large hands on either side of
the teen’s hips, massaging the skin above the shorts. Armin shuddered in his
hold, resting sleeve-covered hands over Erwin’s hold. Erwin pulled the teen
against him, leaning down to press dry lips to Armin’s exposed shoulder. Armin
whimpered, tilting his head to allow his superior more access.
“You… you never said if you liked m-my outfit…” Armin murmured, pressing back
into his Commander. Erwin gripped his hips a little tighter, grinding slightly
into Armin’s ass. The teen moaned, pushing back against him as Erwin continued
to pepper his neck with light kisses and licks.
“I like it very much, Armin,” the older damn near growled. He nipped lightly at
the teen’s earlobe, his hot breath sending shivers down the youth’s spine. “You
look absolutely ravishing right now, and I really don’t think I can keep my
hands to myself.” He emphasized his point by placing one hand flat against
Armin’s stomach and pulling him impossibly close. Armin gasped, hips jerking
back to grind against his superior.
“What if…” Armin moaned, the words catching in his throat as Erwin bit the
junction where neck met shoulder. He brought one hand up to wrap around Erwin’s
neck, the sleeve of his shirt falling to reveal a thin wrist. Blunt nails
scratched over the Commander’s undercut and Erwin released a throaty groan as
Armin arched into him. “What if I don’t want you to keep your hands to
yourself?” he asked softly. He turned his head to place a light kiss to Erwin’s
cheek.
Erwin groaned, burying his face in the teen’s shoulder. “You really know how to
test me,” he grumbled against soft skin, kissing lightly.
Armin laughed, combing his fingers through Erwin’s hair. “Something tells me
you don’t really mind,” he admitted. He suddenly gasped as the hot hand on his
stomach trailed up and under his shirt, fingers dancing over his skin before
finding a nipple. The younger blond whimpered, eyes squeezing shut as he arched
into the attention. Erwin’s other hand gripped his hip almost painfully,
dragging the teen back so he could grind harder against him.
“What was that?” the Commander growled softly. “Was that a little sass I
heard?” His fingers left a blazing trail along Armin’s chest as they abandoned
one nipple to pinch and play with the other. Armin moaned, his back arching
even as his hips bucked back against his lover, his poor body confused by all
the attention.
“It…” Armin gasped, moaning as Erwin bit his neck, sucking none-too-gently on
the soft flesh. “It might have been… O-oh god…”
Erwin pressed a little kiss to the bruise he just made. “I think you’ve been
spending too much time with Jaeger,” he growled in Armin’s ear. But damn it if
a cheeky Armin wasn’t a turn-on. He moved his hand from Armin’s hip over to
palm the boy’s crotch. “You’re hard as a rock,” he groaned.
Armin cried out, jerking his hips into Erwin’s hand. “I-it’s… your f-fault,” he
whined. He wrapped his free hand around Erwin’s wrist on his crotch, and for a
moment the Commander thought he would try to push it away. He was pleasantly
proved wrong and more than a little turned on when the kid did just the
opposite, pressing Erwin’s hand harder against his straining erection and
mewling in his superior’s arms.
“Damn it, Armin…” Erwin groaned, pulling his hand from Armin’s chest and using
it to instead turn the boy’s head towards him. Armin’s eyes were heavily
lidded, a rosy flush to his cheeks, and his mouth parted as heavy pants escaped
him. He looked fucking beautiful and Erwin practically growled as he claimed
the youth’s lips. Armin’s hand in his hair tightened and he moaned into Erwin’s
mouth, responding immediately to the attention. The older blond wasted no time
letting his tongue lick the younger’s bottom lip, plunging in to claim the
youth’s mouth the moment Armin parted his lips. Their breathing was heavy
through their noses, Armin sucking on the Commander’s tongue and earning a deep
moan in response. Nipping gently at Armin’s bottom lip, Erwin pulled away. Both
of them were panting, trying desperately to catch their breaths, but Armin was
the one to pull his Commander in for another steamy kiss. He whined, hips still
bucking against the hand on his crotch and Erwin pulled back to thrust against
his scantily-clad ass.
The younger was the one to break the kiss, throwing his head back in complete
bliss to rest against Erwin’s shoulder. “Oh, f-fu… Fuck, Erwin!” He moaned,
baby blues squeezing shut as his hips stuttered. Erwin immediately removed his
hand, wanting to prolong his young lover’s experience. Armin’s eyes shot open
and he whined in the cutest way. “W-why’d you stop?!”
Erwin chuckled low and deep, feeling the boy shiver. “I don’t want to get your
clothes all dirty.”
Armin gaped at him, cheeks still flushed. “Are you kidding?! These don’t even
count as clothes!”
In response, the Commander growled and roughly grabbed the youth’s hips with
both hands, grinding his own throbbing need against Armin’s ass. “You’ve
definitely been spending too much time with Jaeger,” he muttered darkly. Armin
gave a weak chuckle, the hand behind Erwin’s head falling back to his side as
he rested his weight against the man behind him.
“Jealous, sir?” he inquired.
“Not at all,” Erwin replied.
Erwin loosened his hold on the teen as Armin turned around in his arms. His
breath caught in his throat at the downright sultry look on the younger
blonde’s face, baby blues lidded and lustful, and locked on Erwin’s own. Armin
slid his hands up the older man’s very well-muscled chest, unbuttoning Erwin’s
shirt as he went. “I think you’re jealous,” he breathed hotly, eyes never
leaving Erwin’s.
The commander moaned, cupping the boy’s ass. “And if I am?”
“Don’t be,” Armin murmured. He wrapped his arms around Erwin’s neck. “Levi can
have him. I want you.” He got a decent hold of his lover’s bolo tie and used it
to pull Erwin into another hard kiss.
Erwin’s eyes widened at the suddenly assertive treatment, but he quickly
recovered, shoving his tongue in the boy’s mouth and claiming him once more.
Armin moaned, wrapping both arms around the man’s neck. One hand slid up over
Erwin’s undercut, nails scratching over the stubble before grasping silky
blonde locks and tugging his superior impossibly closer. Erwin groaned, his
hand sliding from Armin’s scantily-clad ass down to his thighs, forcing one leg
up to wrap around him. Armin, smart boy that he was, caught on and jumped up to
wrap the other leg around Erwin’s waist, stocking-clad feet locking at the
small of the taller man’s back. Somehow, their lips never parted, and Armin
clung tightly to his lover as he started walking forward.
When the teen’s back hit the wall, he gasped, and Erwin separated their mouths
to attack youth’s neck, kissing, sucking and biting his way down to Armin’s
collarbone. He gently kissed the bruise he’d made previously and Armin moaned.
Using his feet, Armin brought the older man closer, gasping and throwing his
head back as their groins rubbed together. Erwin let go of Armin’s thighs long
enough to shed his shirt before latching on again.
“Take your shirt off,” his deep voice rumbled in Armin’s ear. Shivers flew up
the teen’s spine at the command and Armin carefully removed his arms from
Erwin’s neck. He grasped the hem of his cut-off sweater and yanked it up, the
bunny ears he forgot about getting caught in the fabric. He made a move to toss
them away but stopped when Erwin growled low in his throat. “Leave them,” he
demanded.
Armin gave him a tiny smile as he tossed the sweater somewhere. “You like
them?” he asked as he put the headwear back on. The lazy ear flopped over
Armin’s eye and Erwin gently flicked it away.
“I think it suits you,” he admitted. He gently kissed the boy. “My little
bunny.”
Armin let out a little laugh. “You’re secretly kinky, aren’t you?” he asked,
leaving a trail of gentle kisses along the man’s jaw.
“Maybe just a little,” Erwin sighed, pressing closer to the boy.
“I knew it,” Armin giggled. He gasped as Erwin angled his hips up, whimpering
as Erwin’s cock brushed against his ass.
“You need to stop with that sass,” Erwin growled. He trailed light kisses and
licks down the teen’s chest, lips wrapping around a pert nipple. Armin whined
in response. He scratched blunt nails over Erwin’s shoulders, down his chest
and over hard abs. Erwin switched to the other nipple and Armin arched into
him, thrusting down on his clothed cock. They both moaned.
“Er-Erwin…” the boy sighed. One of Erwin’s hands traveled to the younger’s
back, hand hot on the boy’s spine as it blazed a path down to the thin shorts
and dipping into the fabric. Armin whined. Erwin gently rubbed a finger over
the boy’s entrance, kissing back up his neck to claim soft lips. “Please,
Erwin…” Armin gasped into his mouth.
As gentle as he could, Erwin slipped his finger pass the tight ring of muscle,
eliciting a rather loud cry from his lover. Armin’s nails dug into Erwin’s
chest, leaving bright red scratches in their wake. The older man immediately
peppered his love’s face with soft kisses, feeling like such an asshole for
putting the kid through this kind of pain. Armin’s face scrunched up as he
focused on relaxing his muscles.
“Sorry,” Erwin muttered sincerely. He continued to ease his finger inside,
earning pained little gasps in response. “Do you want me to stop?” His
breathing was ragged and he really didn’t want to stop, but if Armin said the
word, he would.
Armin slowly opened one blue eye, managing a tiny smile for his commander. “No,
keep… keep going…”
Erwin chuckled, holding still so Armin could get used to the intrusion. “If
you’re sure. I could at least get some lube?”
The teen shook his head, digging his heels in Erwin’s back as he wiggled his
hips. “Don’t… don’t worry a-about it.” Erwin’s eyes darkened as he watched the
boy writhe in his arms. He crooked the digit inside him as he squirmed. “J-
just…AH!” Armin arched off the wall, eyes wide, mouth open, and Erwin smirked
to himself. “Right there! The teen cried. Erwin obliged.
The older man aimed for that spot with every thrust of his finger, slowly
working the teen into a frenzy. Armin moaned and cried out with every thrust,
begging for more already, but Erwin remained steady. He waited until he felt
his lover was loose enough before working in a second digit, carefully
stretching the teen. Armin hissed in pain, but thrust his hips down as best he
could. He was obviously enjoying himself, as evidenced by a small wet patch
soaking through the front of his shorts. His erection was straining against the
fabric, but Armin paid it no mind, too focused on fucking himself on Erwin’s
fingers. Erwin was so entranced by the sight of Armin riding his hand that he
was startled when he felt his zipper vibrate against his own aching arousal.
Hissing as Armin pulled out his cock, he gazed at the youth questioningly.
Armin, always so shy and cute even in such a lewd situation, glanced away,
cheeks flushed with arousal and embarrassment. “I-I shouldn’t be the only one…
mm… f-feeling good…” he mumbled. His small fingers danced over Erwin’s member,
spreading the pre-come gathered at the tip with a thumb and lightly running a
finger along the vein on the underside. Erwin moaned, leaning in to kiss the
boy, scissoring his fingers inside him.
By now both soldiers were a panting sweaty mess and Erwin really didn’t think
he could wait anymore. He slowly, carefully, slid his fingers out, causing
Armin to whine, before adjusting his hold on the boy. Erwin tugged at the thin
shorts as Armin opened bleary, lust-filled eyes.
“These need to go,” Erwin growled, his voice coming out rougher than he
expected. The youth nodded in agreement and Erwin set him down on shaky legs.
As Armin removed the article, Erwin stalked over to his bedside table, locating
a small bottle of oil he may or may not have obtained from Levi. He felt a
little silly walking around with his dick hanging out but as soon as he turned
around, thoughts of removing his pants went out the window.
Armin stood slumped against the wall, knees bent slightly with one hand around
his cock and the other behind him. It took a moment for the Commander to
register that the teen was fingering himself, and holy fuck, that was really
hot. Armin watched him with heavy, dazed eyes, low moans and whimpers escaping
him as he tried to get just the right angle. He whined when he couldn’t quite
reach that lovely little spot inside him and let go of his member, crooking his
fingers at Erwin. Erwin didn’t think he’d ever moved faster in his life.
In a heartbeat, his aching member was coated in oil and Armin was back in his
arms, legs wrapped around Erwin’s waist once more. Erwin cupped his ass,
squeezing the soft mounds of pale flesh in his calloused hands and Armin
wrapped shaking fingers around his length and positioned it at his entrance.
Erwin gave shallow thrusts, easing the head past the tight ring of muscle.
Encouraged by the rather loud (hot, sexy, cute) noises his lover made, he
thrust a little harder until he was buried to the hilt. Armin was so tight, so
hot, and he was gripping Erwin’s member in such a way that Erwin didn’t think
he could control himself. The only thing stopping him from pounding into the
teen was Armin’s teeth threatening to break the skin of his shoulder, but fuck
if that didn’t turn him on more.
He squeezed Armin’s ass almost painfully, Armin whimpering against him. “Sh-
shit…Are you okay?” Erwin asked breathlessly, determined not to hurt his lover.
The teen slowly unclamped his mouth from Erwin’s shoulder. The Commander was
certain he was going to have a good bruise there and he was completely okay
with that. Armin buried his face in Erwin’s neck, nails digging into his back
and leaving red welts that Erwin also wouldn’t care about. The teen nodded. “Y-
yeah…” he murmured, wiggling his ass a little. Erwin groaned, unintentionally
thrusting up. Armin gasped. “S-sorry,” Erwin grumbled, trying to steady his
hips. “I’m sorry…”
“N-no, it’s okay…” the younger blonde mumbled. He moaned into Erwin’s neck, his
breath hot on sweaty skin. “Do that again.”
Erwin did as he was told; gently thrusting up into his lover who somehow seemed
to get tighter every time they had sex. Armin moaned, throwing his head back in
pleasure, wiggling his ass every few thrusts. The Commander growled. He kissed
the younger hard on the lips, steadily picking up his pace. Armin moaned into
his mouth, biting Erwin’s lip as he writhed in his arms, back arching. Breathy
little noises escaped him and Erwin practically snarled. He needed to be
deeper, to pound into his lover and claim him from the inside out.
Slowing down for a brief moment and making Armin whimper in protest, he grasped
one of the boy’s knees and hiked it up to the crook of his elbow. Armin
shuddered at the new angle and Erwin thrust hard into him.
“Fuck!” Armin practically screamed, head thrown back and eyes squeezed shut.
Erwin thrust again. “Ah, s-shit, ri-right there! Please, fuck, right there!”
The older blonde hit that spot again, earning another scream. “Please, Erwin!
More! Fuck me more!” Erwin obliged.
He rocked into Armin slow and hard, enjoying the myriad of filthy words and
phrases spilling from the youth’s normally conservative mouth. He loved that he
could get the little genius so frazzled. It sparked something deeply carnal in
him and Erwin felt his pace picking up, thrusting into the teen faster and
harder. Armin was practically sobbing against him, begging for more and
screaming in pleasure. He clenched painfully tight around his superior’s
length, and Erwin knew he was close. He felt his own orgasm building and he
growled low in Armin’s ear.
“Come for me, Armin,” he rasped out, somehow picking up his already brutal
rhythm. Armin couldn’t speak, could barely open his eyes. The only warning
Erwin got was the tightening of the teen’s ass around his cock and nails
digging into his shoulders before Armin came with a breathy little cry. His
seed coated their stomachs and chests and Erwin snarled as Armin tightened
impossibly around him. With a few more thrusts, Erwin came with a growl,
filling his lover and painting his insides white. Armin moaned, trembling in
Erwin’s arms.
Erwin stood there, holding the youth close as they came down from their post-
orgasmic high, legs and arms trembling slightly from the exertion. He was
reluctant to move, however, wanting to stay buried in his lover’s heat for as
long as possible. Eventually though, Armin started to squirm and Erwin slipped
out with a sigh. The younger blonde managed a sleepy grin.
“Was that good for you, too?” he asked cheekily. Erwin huffed out a laugh,
burying his face in Armin’s neck. He placed a light kiss to sweaty skin.
“Oh, that was very good for me,” he admitted.
“So you liked the outfit?” Armin asked. Erwin set him down on wobbling legs,
kissing him softly.
“I think you should wear it again sometime,” he said, flicking the lazy bunny
ears that somehow managed to stay atop Armin’s head.
Armin wrapped his arms around the taller man’s neck, forcing Erwin down as he
stood on his toes to place a sweet kiss to bruised lips. “I think I can do that
for you, sir,” he whispered.
Erwin smiled, humming against his lover’s lips. “I think I’d like that.”
End Notes
     This was supposed to be up back in February and it wasn’t supposed to
     end there. I didn’t like the original ending so I took it out and now
     it just kind of hangs awkwardly. But meh.
