Levi is strewn across Erwin's bed, half undressed and limbs splayed invitingly.
His lips are already kiss-bitten red, mouth wet and open and panting. His hair lays across his forehead in damp streaks, spreading on the mattress above him like spilled ink.
He's come from training, covered in the sweat he so despises, that Erwin so loves to taste. A bruise dusts light yet insistent across one of his cheekbones. Perhaps a gear mishap, a step gone wrong. Even humanity's strongest isn't perfect.
Well, he's perfect to Erwin. With his shirt buttons undone and pants loosened to accommodate his growing erection, Levi is flawless. Flawless and delectable.
He removes only his jacket before straddling Levi. His hands lock around Levi's wrists and pin them high above his head, while his thighs lock Levi's hips in place, securing his legs.
Levi squirms experimentally. Erwin knows that he could break free. There's no caging this creature, unless he desires it.
He also knows Levi will not escape.
"That's right," he murmurs, leaning down to inhale at the crook of Levi's collarbone. "Give in, Levi. Surrender to me."
Levi whines. His hips buck upward, betraying his quiet impatience.
"Surrender," Erwin repeats. His voice hardens, becoming for one second the commander on the battlefield.
Levi must obey. This is the one and only condition they hold to.
"Eager boy," Erwin chuckles. "Held down and fucked by his own superior. And he all but begs for it."
Levi growls.
Erwin has become skilled at interpreting Levi's wordless communication. Such a long, coiled noise could mean Don't you make me beg for it, or he could be protesting his status as a boy. Or he could simply be putting in his token resistance before he lets Erwin have his way.
"I'll have to open you up first. Slide a finger in you, then another. I wonder how many I could fit inside you."
Levi's teeth click together. His face warms and his eyes snap shut.
Oh?
Erwin leans down so an escaped strand of hair brushes the bridge of Levi's nose. Teasing him.
His narrow features squeeze together even more tightly as another whine forces its way up.
"My fingers, inside you," Erwin continues. He lets his voice drop to its deepest timbre, its most suggestive. "I could hold you like a child as I did so. But of course, I couldn't hold you down at the same time. Could you hold still, or would I need to fetch some cuffs?"
Levi's eyes flutter. His small pupils are dilated, nearly swallowing his irises whole.
"Then I'll take you. Small as you are, I'll split you open. I wonder how hard I'd have to fuck you to affect your performance tomorrow—"
Levi hisses, his small body shaking and jerking under Erwin's weight. His hips buck again, and then he stills. His head falls to the side, where he tucks his face in the crook of his shoulder.
Almost…hiding it.
Wait.
Erwin transfers both wrists to one of his hands, freeing the other to stray down Levi's torso and into his pants.
His cock has softened considerably, surrounded by an unmistakable texture. Erwin smiles.
He gives Levi's member a gentle squeeze, then withdraws his sticky hand.
Levi has come, completely untouched.
"Look at you. Just the sound of my voice was enough to bring you to completion."
Levi squirms, burying his face further in his arm. A delightful flush is spreading down his cheek and neck.
"No, no." Erwin takes Levi's chin in his come-stained hand. Turns his face up. "Don't hide. Let me see. You're perfect like this." He must relish the havoc he's wreaked with only his voice.
Levi truly is radiant in these moments. His tightly wound scowl comes undone, replaced by something vulnerable and unrestrained and messy, and wholly Erwin's. His gaze, always gunsteel and calculating, unfocuses and glazes over. His mouth falls open in a delicate bow, breath gusting from them in audible swells.
No one else can wring this state out of Levi.
His eyes flicker back and forth, barely meeting Erwin's gaze before darting away again.
Erwin kisses his swollen lips open-mouthed, wanton. He tastes the blush on Levi's cheeks, plants kisses on his eyelids, runs his tongue along the still-purpling bruise.
Levi has slumped boneless to the mattress underneath him, utterly undone by one climax. Weak mewls escape him when Erwin's tongue nips somewhere pleasant.
His fingers, always so graceful when he flies and fights, dip downward to brush Erwin's hand.
As clear an indicator as Levi ever gives—don't stop.
Erwin suckles at a spot just below Levi's ear. "I haven't even undressed you," he murmurs. "Impatient. Couldn't even wait for that."
Levi makes a tired noise Erwin is sure is meant to be something like fuck you.
Typical of him. Funny how he never truly tries to.
"I must ask," he says, pulling back slightly to catch Levi's darkened eyes. "Where did you acquire this bruise? Training?"
Levi exhales sharp and derisive, his usual aloofness returning. "Shadis," he says, low and unimpressed. "He asked where I was going when I left. I told him—to see you. For you to fuck me."
Erwin laughs in astonishment. "So he struck you."
He wouldn't believe anyone could be so bold—except Levi. There is no one like this creature, no one in the world.
And Levi is his.
"Well," he says, fixing Levi in place with an intent stare, "I mustn't make a liar of you."
