Work Text:
Eren guided his gray gelding back to Headquarters with a wide smile stretching his lips, his shoulder-length chestnut hair tied up into a messy bun. The mission had gone smoothly, a rarity as the Scout's battle against the Titans was reaching a new intensity. Though the Omega was overjoyed with the success, that wasn't the reason his heart was pounding, full of love, excitement and no small amount of nervousness.
Today was his birthday and not just any one. Eren was no longer a pup in the eyes of those within the Walls. He was eighteen and considered an adult now, something he and his Alpha had been looking forward to and talking about.
Levi had promised that as long as Eren didn't succumb to Heat during this time and the Captain himself didn't go into Rut, that the older would take his virginity and they would have their first time together.
Neither had happened thankfully and though having a mission on this day had caused the man to issue a pissed 'tch' noise in response, the Omega could see how much Levi wanted him in his molten silver eyes.
Eren had no experience outside of Levi. Some part of him bristled at the thought that others had been with his Alpha but that was absurd. Another louder part was thankful for that experience so that the man could guide him.
Levi would make sure to take good care of him.
Shuddering at the thought, the Omega stabled his horse, brushed and groomed the gelding and then entered Headquarters. His friends rushed him in the mess hall and to Eren's shock, they had meat on their plates and alcohol in their tankards.
Viridian eyes rose to the head table to lock with sterling and Eren smiled as he sat down, ignoring the mead to focus on his dinner. He didn't want a single moment of tonight to be hazed with the effects of intoxication.
The Omega was more than aware of when Levi stood and left the table but he didn't follow. As with all of their visits, it was best done when everyone was sleeping. So Eren didn't feel guilty to celebrate with his comrades, the drink actually hastening the others into a stupor. He and Mikasa were the only ones with their wits intact enough to drag the other scouts to bed.
Mikasa paused and looked at her adopted brother before speaking,"you and Levi be safe tonight."
Green eyes going round in shock, the brush Eren was using paused in mid-stroke through his long hair.
"Don't look at me like that. You've been carrying his smell since you were fifteen."
The Omega huffed a breath and shook his head,"I don't want to talk to you about this, Mika."
"Will he be Marking you?"
Eren's brow furrowed and he looked at her with a solemn expression,"no, not until after the war is finished."
The young woman softened at that and nodded before leaving, seemingly satisfied. The Omega put down his brush and sighed. He had a suspicion that pretty much everyone suspected but Mikasa had been the first to be so direct.
But that didn't matter, not tonight.
Standing up, the long haired Omega made his way down the familiar trek towards Levi's quarters and knocked gently on the door. It opened a few moments later, warm silver eyes looking up at him as his Alpha tangled their fingers and tugged him inside.
Eren noticed immediately that the room was lit with only candlelight, the desk free of work for once and the room absolutely dripping with the Alpha's blackberry and lavender tea scent.
The Omega's body immediately lost all tension and he whimpered quietly, submitting to being pulled down and thoroughly scented. Levi breathed out against his glands.
"Good boy. I'll take good care of you tonight, Eren." The dark haired man promised and the taller youth shuddered.
"Alpha…" He breathed but couldn't find any of that previous anxiety, not with so much of Levi's scent against and around him.
Probably intentional and Eren was so glad for it.
"Come on, baby. Let's get you cleaned up." The Alpha crooned and the brunet nodded, Levi guiding him into the bathroom to discover it also lit with the light from candles. The bath was full and steaming but when Eren made to undress, the older man halted him.
"Let me."
Biting his lip, the Omega obeyed with widened bright green eyes. He watched as pale, deft fingers first divested him of his green top and then worked his trousers open. Both they and his briefs were pulled down in one smooth motion, Eren having walked here barefoot.
Fully nude in front of his Alpha for the first time, he couldn't help the flustered blush coloring his cheeks. Levi's gaze was a physical thing as it took in every inch of bare flesh, pausing to admire his neck, his nipples, his pussy and his thighs. Calloused palms eased onto his hips and guided him into the water.
The Omega began purring as Levi began to wash him, the treatment unexpected but very much appreciated.
"What about you, Alpha?" Eren questioned softly and even though he wasn't looking, he could feel the Captain's smile.
"I've already bathed waiting for you. Don't worry about me." The deep voice crooned in a low tone and Eren shuddered. He was washed with soap from head-to-toe with gentle efficiency and when Levi washed his long hair, the Omega was sure the Alpha seemed to enjoy that as much as Eren was.
His purr only deepened as the older toweled him dry. However it cut off with a startled squeak as Levi picked him up and bore him down into the mattress. Eren opened his mouth to stutter as his face heated up but his lips were claimed, silencing anything he had even been thinking of saying.
Eren moaned into the kiss and twined his tongue with Levi's, more skilled and knowing exactly how his Alpha liked it after two years of practice. Levi rumbled into his mouth, swapping saliva with broad strokes until they broke apart with a wet noise.
"You're gorgeous, Eren."
Warm silver eyes took in his body and the chestnut haired Omega whined, pulling at Levi's shirt pleadingly.
"You too. I want to see you too, Alpha."
A small indulgent smile tugged at the older man's lips before Levi was stripping for him. It wasn't a show, it didn't have to be. His Alpha's body was exquisite. A work of art forged in battle. Not one bit of the shorter Alpha's body was wasted, packed with honed muscle covered in pale skin, with even lighter scars littering that expanse. Most of that body was hairless aside from his legs, the happy trail on his navel and the nest of hair above his cock.
Eren swallowed and whined needily at the sight, parting his thighs a bit in want. His Alpha was already hard and leaking, thick and long both and Eren just knew that Levi's knot would stuff him perfectly.
His Alpha's silver eyes darkened in lust at the sweet smell of Eren's slick, the Omega opening his legs all the wider to show how it drooled from the lips of his cunt.
"Fuck, Eren…" Levi snarled and the long haired youth purred, feeling desired by his soon-to-be mate.
"Please…" He begged and it seemed the Captain didn't need anymore coaxing. Palming his thighs, Levi wrapped long legs over his shoulders and pressed close.
Viridian eyes fluttered and then closed as Eren felt the blunt tip of Levi's cock nudge against his clit. He shuddered as it was dragged over the sensitive nub and then down through his soaking lips. Becoming drenched with Eren's slick and teasing at his virgin hole before his hips were taken in a firm grip.
He expected Levi to plunge right into his cunt and claim him but that wasn't what happened.
Instead, the dark haired Alpha canted his hips at a certain angle and simply dragged his heavy cock against Eren's pussy. Flushed and panting, the Omega moaned at the delicious drag against his twitching clit. Slick bubbled and oozed from his hungrily clenching pussy as Levi simply fucked against him in a smooth glide.
"Ah! Levi…Levi!! Alpha, please!" Eren pleaded and the Captain chuckled, continuing to move but not inside where the Omega desperately wanted him.
"You smell so sweet, baby. So wet for me."
Eren moaned when that thick tip caught just a little on the hole to his needy cunt.
Trembling, Eren whined long and low,"Alpha, please! I need you! I've waited so long!"
Silver eyes bore into his own, both hungry and fond,"you have, Eren. You're such a good boy. Are you ready to be my mate?"
"Yes!" The youth sobbed, almost crying in frustration,"I've been ready! Alpha, please!"
Then Levi's hips shifted and the breath was punched out of Eren's chest as the tip caught and sank inside on the next pass.
"Ah!"
"Easy!" Levi's hands steadied him and held the Omega firm,"breathe, baby…. Fuck, you're still so tight!"
Eren whined on a shaky exhale, tears welling in his eyes as he struggled to calm himself. The stretch was already so much and Levi couldn't even be halfway inside. A roughened thumb circled his clit, causing the Omega to shudder.
"Just relax and breathe…. That's-" Levi suddenly sank in another inch,"that's so good, Eren! Good boy! Open up for me, Omega. Let your Alpha all the way inside!"
More slick rushed past Levi's cock, easing the way for the Alpha to sink inside bit by bit, praising the keening Omega the whole time. Until they were pressed as close as possible and Levi hilted to the root inside his younger mate.
"Oh fuck, Levi, you're so big!" Eren had tears running down his face, overwhelmed at the stretch but purring as he looked down at how their bodies were joined together. His Alpha was perfect. Hot, heavy and stretching him out in all the right ways.
Levi's hands tightened on his hips and the dark haired Captain eased out before rushing back in, the sweet drag forcing a cry from Eren's lips. Every new thrust worked him open, spreading him and forcing his walls to give in to the insistant pressure.
Then the Alpha struck something deep that had Eren wailing, eagerly meeting his pace now with a greedy edge when before had been hesitation.
"There it is."
"Oh Levi, there! Fuck me there!" Eren keened and a dark growling rumble greeted his words.
"Fuck you there? Want me harder, baby? Deeper?" The Alpha asked with a flash of fangs.
"Harder, deeper! More, Alpha!"
Levi immediately set a ruthless tempo, pumping his dick into Eren's clutching walls, the Omega scratching down the Alpha's back as his thighs parted as far as they could go. His eyes rolled as that sent his mate even the slightest bit deeper. The pleasure was building and undeniable. Eren moaning as he arched his back into the Alpha as that cock plunged inside with each pass.
The peak struck him without mercy, the Omega screaming his Alpha's name as he squirted sweet slick all over Levi's huge cock. It only made it easier to fuck him faster, making the youth keen in overstimulation as he was held firm. Writhing under the strong Alpha as he was rutted into.
The press of Levi's swelling knot quickly had Eren no longer caring that his pussy felt too much, too raw with pleasure.
"Knot me, Alpha! Give me your knot! Please! Please! Levi!" He begged, his legs pulled from the man's shoulders to spread as wide as they would go without shame, jolting in the air with each rough thrust. Levi pinned one leg down, gripped one of Eren's hips and fucked into the Omega's sloppy pussy.
"Fuck! That's it, baby!"
Eren keened as Levi slipped in halfway.
"Take my knot in your greedy cunt, Omega!"
Eren tipped his head back and screamed in pleasure, his hole stretched impossibly wide before Levi lurched forward and snarled as their bodies locked. Knot popping inside, Eren came hard for a second time, Levi cussing and groaning as his walls clamped on him. Babbling, purring and moaning, the Omega milked the older Alpha, tip to knot until Levi finally came with a shout.
Keening at the hot release flooding his walls, pumping deep and coating his insides thick, Eren tightened his hold on his mate and pulled him close. Levi panted hard and caught his breath before gingerly rolling them both to remain locked together more comfortably.
The Omega began purring in the afterglow, blissed out and happy. Lips groomed his scent mark but never bit down, as much as Eren wished for it.
"My fangs will sink in here…once the fighting is done,"his Alpha murmured the promise with an uncharacteristic softness.
Eren chirruped happily at the thought and a hand eased down his arm before taking one of his hands. Pale fingers toyed with one of his own.
"But before that…I'll give you a ring to wear. As soon as the last Titan dies."
The Omega stilled and blinked, realizing Levi was stroking his wedding finger.
"Levi…"
"And what was that other very light condition you set on our first date?"
Eren blushed all the way up to his ears but he couldn't be embarrassed when his Alpha's free hand moved down to rest on the Omega's flat stomach.
"How many? I'll give you everything, Eren." The Alpha growled and the younger moaned as his mate grinded his knot deep.
"F-Four! At least four!" He whimpered in response and Levi chuckled before holding him close, nuzzling into the Omega's scent glands longingly.
"Everything for my mate."
Eren softened and tangled his fingers with Levi's.
"As soon as the war is won," he whispered and the Alpha rumbled in agreement.
"As soon as the war is won."
Their fingers tightened around each other on that promise.
