It didn’t happen overnight.

At first, Armin touched you like you might break.

Soft.

Careful.

“Tell me if it’s too much,” he whispered the first time his hands slid under your shirt, voice trembling.

“I just want to make you feel good.”

And you had.

God, you had.

But tonight?

The man who pinned you to the door?

Was not the boy who once blushed at the sight of your skin.

This was Commander Arlert.

⸻

It started fast.

The door slammed shut, your back hit the wall hard.

Armin’s mouth was on yours immediately — rough, possessive, starving.

You gasped into the kiss, but he didn’t let up.

“You’ve been teasing me all day,” he growled against your lips.

“The way you smiled, the way you bent over the damn table—”

“You think I didn’t notice?”

You whimpered, trying to pull him closer.

He caught your wrists — pinning them above your head with one hand.

You struggled, but he just chuckled darkly.

“Stay still,” he murmured. “Or I’ll make you.”

The threat sent a shiver racing down your spine.

You nodded.

Armin smirked.

⸻

He stripped you fast — almost impatient.

Your shirt yanked over your head, your pants shoved down, your skin exposed to the cool air.

He kissed your throat, your collarbone, your chest —

biting down just hard enough to make you gasp.

“You look so good like this,” he muttered, lips brushing your skin.

“Mine to mark. Mine to fuck. Mine to ruin.”

You whimpered, legs trembling.

“Please, Armin—” you whispered.

He pulled back, blue eyes dark and dangerous.

“What do you want, sweetheart?”

“You want me to make you forget your own name?”

You nodded desperately.

Armin smiled — slow, wicked.

“Good.

You’ll beg for it.”

⸻

When he finally pushed inside you, it wasn’t slow.

It was deep.

Hard.

Devastating.

You cried out — nails scrabbling at his shoulders — but he caught your chin in one hand, forcing you to look at him.

“Eyes on me,” he commanded.

“I want to see how good I fuck you.”

You moaned again, helpless.

He set a brutal pace — slamming into you with no mercy, no patience.

The sounds — skin against skin, desperate gasps, broken cries — filled the room.

Armin pressed his forehead to yours, panting:

“So tight for me,”

“So fucking perfect,”

“Nobody else gets to see you like this. Nobody.”

Your legs shook.

You tried to beg — for what, you didn’t even know — but he shushed you, voice low and ragged:

“Give it to me, baby.

Let go.

Want to feel you fall apart on my cock.”

You shattered with a scream —

clenching around him so hard he groaned your name like a prayer.

“Fuck— that’s it— that’s my girl—”

“So fucking beautiful when you break for me.”

He held you through it —

thrusting through your orgasm until you were a boneless, trembling mess.

And only then —

only then —

did he follow, biting your shoulder to muffle his own broken moan as he spilled inside you.

⸻

Armin stayed there for a moment, breathing heavily, forehead against yours.

Then, slowly, carefully, he slipped out — catching you before you could collapse.

He kissed your hair, your forehead, your cheeks, murmuring between each kiss:

“You’re okay.

You did so good.

So proud of you.”

He carried you to the bed, setting you down gently, like you were made of spun glass.

You whimpered as he wiped you down, cleaned you carefully — murmuring soft apologies even though you clung to him the whole time, not wanting him to go far.

When he finished, he pulled you into his lap — wrapping you tight in a blanket, cradling you against his chest.

Kissing every mark he left on your body.

“Look at you,” he whispered, brushing his fingers over a deep bite on your shoulder.

“So pretty with my marks all over you.”

“You’re mine,” he said again, voice rough and quiet.

“No one else gets you like this. No one else ever will.”

You nuzzled into his chest, heart aching with how much you loved him.

Armin stroked your hair, kissed your forehead.

“Rest now, sweetheart,” he murmured.

“I’ll be right here.

Always.”

And you believed him.

Because you were his.

And he was yours.

Always.

Masterlist

"F-fuck."

A stuttered curse, breathed into the heat of the room, blond head thrown back in tandem with the word and looking statuesque as he did---he looked like a painting of perfection, one that I'd painted in my own colors. Crystalline eyes welled with tears, almost heartwrenchingly beautiful as the smell of copper permeated the air, lips stained with rustic red as pearly white teeth snagged on a plump lower lip.
