Why did it always lead to this?

Ever since he could remember, Eren was punished with a knee to the jaw or a fist to the eye, and the phrase "shitty brat, why don't you just listen?" strung along behind it. The phrase is what hurt Eren the most; even if he was told about Levi's inability to converse well with other humans. He couldn't control his feelings, he was just a teenager! That had been his excuse for the longest time, but now he's not so sure it's justifiable.

The first time it happened was a month ago, one fucking month ago that Levi had surprised Eren out of anything that would have left his lips. Any retort, stammered phrase or insult to come from his mouth had been swiped away with one single kiss.

"Oi, Jaeger." Levi grunted and Eren groaned (great, another beating?), standing at attention and eyes locked onto the Corporal's. He watched him carefully, watching a canine come from under his lip to bite down on his bottom one, eyes trailing - wait, trailing down? - along his taller, leaner frame before he took a stride to stand flush to Eren. He was much shorter than Eren, but that didn't stop him from standing on his toes to brush their lips together.

Eren stumbled back because, fuck, the Corporal was kissing him. His lips were smoother than he could ever imagine and he almost fell backwards, Levi's strong hold keeping him upright. It was a languid kiss, lips sliding and Eren couldn't help himself as he relaxed into the kiss and wrapped his arms around the Corporal's waist.

The kick to the face wasn't short behind and he left Eren with a bloodied nose (from the kick or from the arousal pumping through his veins? he couldn't tell), and he almost laughed at the sight of the Corporal down the hallway where he thought he was out of Eren's sight, leaning with one hand against the wall and blushing like Eren never thought he'd see.

But oh, has he.

And that is how they got here; Eren's thin wrists were tied to the bed, the soft fabric snaking around them as he struggled and cried out, already on the verge of tears. Oh, how pathetic he felt.

"C-Corporal!" He managed, eyes on the man that hovered over him, a sly smile adorning his lips.

"Yes, Eren? What is it?" He tried to sound displeased, but Eren could tell he felt pride at how weak he sounded below him. He leaned down, a barely-there kiss pressed to his right shoulder blade. "Tell me. Tell me what you want."

"I-I want you to fuck me, Corporal." He said, meek and small; God, how Levi has craved for this…

"Really now, I didn't know." He bit, ghosting kisses and touches all over his body and fuck, Eren didn't know what direction was up when those hands were on him. They were softer than he had ever imagined; then again, of course, so was Levi. He was an exceptional lover, something you'd never expect from a man like him. His touches almost caresses and his words exceptionally chimerical; Eren mewled as Levi flicked his tongue over the boy's head, guttural words coming from Eren's mouth.

Levi hadn't expected that. Maybe more begging, more struggling, but definitely not that. He knew Eren was German; he didn't know he knew German. But, did it really matter? Levi wasn't sure if something had ever turned him on so much in his life. He was suddenly sure as Eren let more German slip past those pretty pink lips, a faint blush painted across his cheekbones.

"Berühre mich hier, Corporal. Bitte. Bitte." He sounded and looked strangled as he panted the phrase out. He hummed and choked below him and Levi couldn't help the blush that spread down his neck. Oh my. Levi smirked deviously as he leaned down over him again, leaving the smallest of spaces between their lips.

"What was that, chérie?" And Eren gasped, pulling viciously at the restraints because, fuck, it did wonders when Levi spoke in French. He'd only heard it once, and in the tone of voice he was using, too. That's the reason Eren spent twenty minutes in the bathroom that evening; he would never tell Levi that.

"Levi, ich kann nicht mehr warten! Bitte, bitte, ich brauche dich!" Oh, did Levi love it when Eren called him by name. He didn't want him to call him that in front of the others. Only when they're like this would he allow it.

"Fuck." Levi ground out, finally, finally smashing their lips together for a heated kiss, Eren so desperately wanting wrap his arms around his neck and let his hands play with the fuzz on the back of his neck. The kiss was over too soon, though; he broke off and kissed down his body, no longer feather-light like before but hard ones that left the spots a dark, deep maroon color. Oh, how wonderful that felt.

He was exceptionally quick, too, entering Eren before he could decide where Levi had gone. He seemed to be everywhere; Eren's mind was buzzing so much he couldn't tell where anymore. His hands were untied and he grasped onto Levi, wailing and moaning as Levi pounded into him.

It went quick, for both were already on the very edge; it was Eren who came first, throwing his head back and yowling out Levi's name. God, Levi couldn't handle how Eren said his name, low and deep in his throat, thick with an accent and he groaned into his neck, not caring for the mess on his chest as he rocked in and out and murmured into Eren's ear. The boy's ears turned the same color as the blush on his cheeks, ducking his head into the side of Levi's neck and humming softly. Levi smiled, thinking Eren wouldn't see the small act of adoration as he continued to rub his back.

There are quite a lot of things that Eren has seen; Levi will never know how much Eren loves him for them.
