NSFW Eruri Week

“Good.” He nudged Erwin’s legs apart with his knee and stepped between them. A heat settled on the back of his neck as he drank in the sight of his Commander, bound and meek before him, powerful hands pinned behind the chair he sat in.

His voice was softer than Erwin had ever heard it. “You’ve been in charge of so much for so very long. Such weight on your shoulders…” He trailed his fingertips across the shoulders in question as he spoke, relishing in the older man’s shiver. “Never allowed to show weakness, to submit…”

A vulnerable noise bubbled from the back of Erwin’s throat. He squeezed his eyes shut, trying to keep his composure. Everything the Captain was saying was true, but this vulnerability was utterly alien to him, and it itched under his skin. He shifted, lifting his chin out of Levi’s gentle grip. “It is my duty.”

Levi tsked, allowing him to refuse his touch, for now. “Your duty, yes. And you fulfill it so admirably, Commander.” The title, so often spoken with reverence, suddenly sounded like a tease. “One might wonder how a man of your strength, your integrity, ever finds respite, release…”

Erwin laughed helplessly. “Respite, release. More luxuries.” 

Levi ignored him, deft hands now sliding down Erwin’s broad arms, the planes of his firm chest. “So lonely at the top, isn’t it? Always giving orders, never taking them. No one to give them to you…” He shook his head in sympathy. “I am your loyal Captain. Am I not?”

“Yes. Yes, of course you are.” 

Levi’s fingers dipped below Erwin’s collar. “And you trust me, Commander?”

“More than anyone. More than myself.”

“You honor me,” Levi whispered, his lips at Erwin’s ear. “Allow me this.” He traced the Commander’s sharp collarbones, sliding the shirt off his shoulders. 

Erwin held himself still, eyes falling shut under Levi’s gentle explorations. “What are you-”

“Shhh.” Levi placed his fingers to Erwin’s lips. “Don’t question me, soldier.”

Erwin shuddered, a spark flying down his spine at the low command. “Yes, sir,” came his whispered response.

Levi smiled sharply, his lips now at Erwin’s knitted brow, then trailing the column of his neck. Chaste kisses that burned where they fell, phoenix feather-light. The role reversal made Levi’s skin crawl, his heart soar- improper, delicious, necessary and right. He reached for the medal on his Commander’s neck, yanked his face closer by the thin cord. 

When their lips met, Levi thought he might die, drowned in the tide of Erwin’s ragged breathing, crushed under the weight of his tongue in his mouth. Erwin, for his part, was ravenous for the taste of his Captain, aching to take him in his arms and devour him whole. Tied to the chair, he was forced to Levi take the lead in a way no one ever had with him before.

Levi swallowed Erwin’s moans eagerly, steadying himself with his hands on the man’s hips. The chair threatened to tip as the kiss continued, both men breathless but unwilling to part for air. Levi broke first, staggering back with a gasp as Erwin strained to chase his lips. 

The Captain’s eyes were bright as stars as he knelt before his Commander. Erwin gasped, opened his mouth to say something, but the words stuck in his throat as Levi unfastened his trousers. Erwin’s cock sprang free, greedy and slick with pearls of precum. Levi smiled, touched his tongue to the blonde’s drooling tip. 

“You’re beautiful, soldier,” Levi purred, Erwin’s cock jumping with the heat of his breath. 

“Thank you, Levi,” Erwin rasped. Levi jerked his mouth away and frowned.

“Levi? I don’t think that’s an appropriate way to address your superior officer.”

Erwin bit his lip. “Wh- what do you want me to say?”

Levi considered. “I want you to say please. And use my title.”

“Please, Captain.”

“Mm, much better.” Levi lowered his mouth to Erwin’s cock again, flicking his tongue against the vein that ran beneath his shaft. Erwin fought to roll his hips up, desperate for more stimulation, until Levi finally acquiesced. 

The Commander’s eyes rolled back as Levi took him into his mouth. Levi’s intensity was overwhelming at the best of times, but it was utterly devastating now, directed wholly at Erwin’s body. He hollowed his cheeks as he swallowed him deeper, skillful tongue laving over his throbbing head with each suck. 

Erwin curled his hands into fists behind the chair, crying out as he hit the back of Levi’s throat. Levi choked, the spasm sending Erwin into a frenzy. “Captain, please, you’re killing me…!”

Levi shoved himself all the way down, sharp nose pressed against Erwin’s abs. His entire world narrowed to the moans that wrung from the man above him, the clench of muscular thighs around his head, the musky taste of the cock down his throat. He couldn’t breathe, didn’t want to breathe, didn’t need to breathe. 

Erwin’s smooth blonde hair had fallen out of place, glued to his forehead with sweat as he stared down at Levi through heavy-lidded eyes. He had never seen anything as beautiful as the Captain on his knees, in complete control even as he gagged and drooled onto his own trousers. Erwin’s fingers twitched, wanting to tangle in the other man’s hair and wring the pleasure from him, wanting to stroke his flushed cheek. They adored each other wordlessly.

Levi tore himself off of Erwin’s cock, gasping for air. He didn’t seem to notice the tears that ran down his cheeks, his ever-scowling face smoothed into something like awe. He roughly shoved the Commander’s shirt up, pressing hot, needy kisses to the exposed skin as Erwin whimpered for him to come back, to finish him-

“Shut up, soldier.” There was no real strength behind the words. Levi’s firm voice was ragged with want, and Erwin was no better, whimpering at the command. 

Levi returned to his task, bobbing his head with new urgency as he felt Erwin tense and throb on his tongue.

“Captain, I’m going to- I’m close, you can’t-” Erwin tried to pull his hips away, but Levi clung to him furiously. He swirled his tongue faster, long fingers caressing Erwin’s base whenever his mouth left it, not allowing any part of the Commander to remain untouched. 

“I want you to cum in my mouth,” Levi murmured, cock-drunk and demanding, spit-slick chin propped on Erwin’s knee. 

“What? You want me to-” 

“That’s an order.” Levi’s eyes flashed, no room for argument. “You’re going to cum down my throat, soldier.” 

Erwin groaned, his head falling forward in defeat. “Yes sir.” 

Levi spat on the Commander’s cock, smiling wickedly up from his knees before surging forward to devour him again. Erwin’s whole body was electrified, tense almost to the point of pain as he hurtled toward his peak. The skin around his wrists were rubbed raw as he twisted them, his medal of honor red-hot where it lay against his burning skin.

“So good for me,” Levi mumbled around him. Erwin trembled, ached, thrust himself deeper into the wet heat of his Captain’s mouth. 

“I’m…fuck, L-Levi- Captain..!” Erwin’s voice broke as he fell apart. Levi took him to the hilt, steely eyes locked on the beautiful collapse of his Commander. The burning ache in his jaw, his knees, the sacrificial strain of the act was forgotten with each burst of Erwin’s bitter cum on his tongue. Levi swallowed it desperately, the sticky fluid an absolution, eager tongue darting out to catch the drops that spilled over his lips. 

“Commander…” he groaned. 

Erwin’s eyes were wild, pupils blown wide, an eclipse over the sea. “Erwin,” he corrected firmly.

“Erwin…” Levi repeated it like a prayer, shaky hands undoing the belt that held the blonde’s hands back. As soon as it fell free, Erwin swept Levi into his arms, thumbing away the tears still drying on his red cheeks, his swollen lips.
