Chapter Text
"Ready to admit defeat?"
"Never!"
Levi chuckled as his younger adopted brother managed to buck out of his grip, a leg coming around to attempt to force him off. A useless endeavor, they both knew, especially when Eren was already panting with exertion. It took almost no effort on the older's part to keep his sibling pinned.
It was often they had these good natured tousles, competition was healthy. As opposed to when Levi first came to live with the Yeagers and Eren felt threatened as an only child. He had only been ten while Levi had been fourteen. Yet it had only taken a week for the brunet to accept his new sibling. He's not sure who told Eren his backstory as that definitely wasn't age appropriate but they had been inseparable since.
Of course they still had arguments but nothing as explosive as that initial meeting.
Eren groaned and shifted beneath him, trying to free his arm and growling his name with a challenging grin.
Levi adored Eren and once they had bonded as brothers, the brunet could always be found at his side. His other friends wondered how he didn't find it annoying but Eren was never a burden or bother. Something had simply clicked upon their meeting and Levi had sworn to protect his younger sibling.
Loving Eren was as easy as breathing.
"Hah!"
Levi smirked as they rolled across the floor, fighting Eren's longer limbs and managing to remain on top. Their bodies slotted together and Eren bucked with a breathless laugh.
"Give up, Eren?"
"I can pin you, just you wait!" Hips bucked up into him as Levi blinked, tilting his head as his silver eyes shined with amusement.
"Not gonna happen," he taunted with a small smirk. Eren let out a mock cry before shockingly rolling them both. They tumbled and for a moment, Eren was on top and frantically moving to pin Levi down but that quickly passed as the older sibling forced them both back down.
The dark haired man landed on the taller brunet, their hips slotting and Levi froze the same instant Eren did.
Both brothers were wide-eyed as Levi's brow furrowed, tilting his hips to confirm the situation. Fuck, they were both hard and pressed impossibly close.
Mutual fear shone in both sibling's eyes.
This was wrong.
This was taboo.
Levi or Eren should be jerking out of this position right away, awkwardly laughing the situation off. He wasn't holding the other youth down after all…. Then why hadn't Eren done it?
Why couldn't Levi move? He was the older brother, he should be doing the right thing! But Eren wasn't moving, those rounded green eyes staring up at his older brother.
A tentative roll had Levi gasping, unconsciously tightening his grip on Eren's pinned hands. Frantic silver eyes searched the youth's face. The fear was melting into a pleading expression, the other boy flushing all the way to his ears.
"Eren…" He breathed out, fear still licking up his spine. 'What are you doing?' His gaze questioned desperately as his brother repeated the action just as cautiously as before. The sweet drag of clothed erections felt so good.
"Levi…" Eren whispered, tears welling in those beautiful viridian eyes as his hips stuttered a third time.
"We can't," the dark haired boy murmured and Eren shook his head, staring up at Levi with such a vulnerable expression that it felt like his heart may break.
"We don't need to tell anyone!" He rushed out,"it can be our secret!"
Levi's silver eyes widened as realization struck him,"do…you want me like this? Even though we're brothers?"
Eren swallowed and they stared at each other as the delicate and fragile moment stretched on.
"Yes.”
The confession was fearful but so full of longing that Levi couldn't breathe for a moment. His gaze took in his sibling's features. Eren had grown up to be beautiful. There was no question that Levi was attracted to him but…
"This can destroy us." He warned in a tight voice and a shaky smile was his response, Eren shaking his head to show he didn't care.
"As long as I'm with you, I feel safe and loved. Is it wrong if I love you too much?"
No. Nothing Eren could do could be wrong, especially with how the boy loved. With his entire self, placing his whole heart into Levi's hands. The dark haired youth would never crush it. He couldn't.
"Your love is never wrong, Eren," he whispered and his sibling gingerly freed his hands from Levi's loosened fingers. They cradled his face as if handling his pale skin too roughly may break him.
"Levi…please…"
Levi's brow pinched as if pained, hearing all the horrible things that may happen roaring at the back of his mind. But they were still pressed close, still caught in this moment.
"I love you, Levi. Please…. Please don't leave my side." Eren's voice was shaking and those tears finally fell.
The last of the older brother's resistance fractured. He leaned down and pressed their lips together for the first time, hot and chaste but brimming with want.
"Never, I'll be right there with you, forever," he swore hotly against Eren's parted lips before claiming his sibling's mouth again, eagerly tasting Eren as their hips began a lazy roll. The desire was a sweet burn, the clothed drag of their erections causing both teens to sigh into the kiss.
Lovely sparks of arousal laced their blood and their combined noises of pleasure rang into the otherwise vacant house. Levi began a rougher pace, enthralled by how Eren's head tilted back and how he keened, so very responsive.
"Hah-! Ah! Levi!"
Levi groaned and leaned down to taste every inch of his brother's mouth. Eren broke the kiss with an urgent whine,"I! I'm going to cum, Levi! Gonna!"
"Shit, Eren. Cum for me, little brother. I want to see you fall apart!" He growled. Their hips stuttered and warmth wetted Eren's pants, silver eyes darkening at how gorgeous his sibling looked like lost in pleasure.
It would only be him.
Those expressions were only for Levi.
Eren belonged to him.
Always.
And forever, belonging only to him…
Still hard, Levi picked up his blissed out little sibling,"I love you too, Eren. We'll keep this secret and you'll always be mine."
He carried them into his room, glancing behind them with flashing silver eyes before turning and locking the door behind them.
Always and forever.
