"Get off me. You stink." Levi mutters, pushing at Erwin's shoulders.
Erwin replies by showering Levi's upper body with tiny kisses
"Stop it," Levi whines, feeling the heat rise in his body once more. Erwin pouts. "No. No more sex. I need sleep."
"But Levi-,"
"No."
"I thought I was the Alpha in this relationship?"
"Yes, but you're completely wrapped around my finger," Levi explains, taking Erwin's distraction to finally push his body off of his own. "Any more sex and I won't be able to ride my horse tomorrow. How are you going to explain that? 'I'm sorry soldiers, Captain Levi can't join you on our exercise because I fucked him too many times last night. Oops.'"
"But you love it anyway," Erwin drawls, moving to kiss his neck again.
Well, that is true. In fact, he particularly loves the burn left over from an intense night of debauchery with Erwin.
He lets a quiet moan escape his lips while Erwin showers his neck with kisses. Another round of sex wouldn't be too harmful, surely. And Erwin is particularly irresistible tonight, although Levi can't place his finger on exactly why.
In fact, Erwin's been extremely irresistible for a while now. Even when Levi's been dead focused on work, his mind can't help but slip and think about Erwin for a couple of seconds. It feels awkward to be apart, like they're clingy teenagers who can't control themselves. His libido has also risen, with the two of them having sex every night for multiple rounds each time. Not that it's a bad thing - because sex with Erwin is the best fucking thing in the world - but it's also very time consuming and exhausting. They both have jobs to do, and they vowed that their relationship wouldn't get in the way of it.
And Levi's starting to think it's becoming a problem.
Erwin is now thoroughly sucking on his scent gland and Levi's eyes roll back into the back of his head in pleasure. "Alright, one more round," Levi relents. "But you're doing the work and no knotting. Be gentle."
"Yes sir," Erwin mocks.
"Just shut up and fuck me, Commander."
"I know exactly what's going on," Hanji says nonchalantly after Levi voices his concerns with her. "You guys have been together for what? Two years now?"
Levi nods.
"And you haven't mated, have you?"
"No…"
"Well there's your problem," Hanji says simply. "You two have formed the emotional connection that mates have, but you haven't followed it through physically."
"But he's knotted me more than enough times," Levi replies.
"You know there's more to mating than that. Knotting is a part of mating, yes, but you also need to be biting each other's scent glands, rubbing your scents off on one another and having pups together."
"But that's not an option," Levi growls. "We can't give away any inclination that we're together and we most certainly can't have pups." Even so, he still catches himself looking in the mirror and wandering what his stomach would look like if it were swollen with Erwin's pups.
"You should still be biting each other's scent glands. It's all about symbolically recognising your relationship outside of sex. You've formed the human, emotional connection, now you just need to form the animal, physical connection. The attachment and heightened libido should calm down after that." Hanji explains. "You have your cravat which should cover it any marks made to your neck. And I can think of something for Erwin. Problem solved."
He's long gotten over the shock of being in a committed relationship with an Alpha, and his trust issues have mostly been solved by many long discussions with Erwin, but he still can't help but feel a rational hesitation to the idea of mating with Erwin. And not just because he's an Alpha, but because of their jobs.
Mating is supposed to be a lifelong commitment, and once a bond has formed, it's unlikely that you'll form a stronger connection with anybody else, and Levi hates the idea of leaving Erwin so broken and alone when he inevitably dies. He'd much rather leave now and let Erwin mate with somebody else who will be with him forever.
But they're probably too far-gone for that. A connection has already been made, and now they have to live with the consequences.
And the animal part of his brain is screaming at him to do it. To let Erwin take him and claim him and own him. He trusts Erwin enough, he really does, and his body tingles just at the thought.
Maybe they do need this.
"I'll talk to him about it," Levi concludes.
Hanji squeals, clapping her hands together. "Great! I'm so excited!"
Levi rolls his eyes and goes about his business with a slightly uplifted demeanour.
That night, Levi finds himself being pulled by Erwin into their bedroom.
"You're okay?" Erwin asks, hands grabbing as Levi's body, checking for any sign of damage.
"Yeah," Levi says, slightly dazed, "Why wouldn't I be?"
Erwin calms slightly. "You're usually here before me, and I guess I freaked out a bit when you weren't here…" He continues to stare at Levi's body, eyes turning dark with lust. "I've been thinking about you all day."
"I was resolving a fight in the barracks," Levi says, breath hitching when Erwin starts rubbing at his crotch. He can feel his asshole dampen and twitch at the feeling of an Alpha manhandle him. "Those stupid Alphas couldn't control themselves."
Levi is often called in to diffuse situations between hormonal and territorial Alphas, and Levi knows that Erwin knows this (he's usually the one to bring Levi in anyway), but Levi can still smell the jealousy emitted from Erwin.
"So you're spending your nights with other Alphas now?" Erwin asks, pushing Levi against the door, hands tearing into his uniform. If he was in a sound mind, he'd bitch at Erwin for ruining yet another uniform, but once again, he's too blinded by lust to care.
"N-No," Levi whines, bucking his hips up. "I'm- I'm yours, Erwin. Only yours. Always yours."
Erwin tears his own clothes off and lifts Levi into the air so that his legs can wrap around his waist. Levi moans, high and breathy as Erwin's cock brushes against his hole.
"Tell me more," Erwin mutters, hips lightly thrusting against Levi.
"You're the only person who gets to touch me and see me like this- fuck, Erwin, you're the only one I want. Just you."
Erwin's free hand wraps around half of Levi's neck, with his thumb pressed against his scent gland.
Levi's body jerks as Erwin presses down. "Fuck!" He cries. Erwin's mouth is also close… So close… Just a few inches and his teeth could be biting down and marking him and mating him and fuck, fuck, fuck… "Erwin… Erwin please…"
"I have you," Erwin whispers, easing his fingers off Levi's neck. "Are you okay?"
Levi nods frantically. "I just- Fuck me already, damn it!"
Erwin chuckles before lining up his cock and fucking Levi hard against the door. Levi's body writhes in pleasure, pliant in Erwin's arms. When Erwin reaches his climax, he starts to pull out, but Levi clings to him and hisses, "No. Stay."
So Erwin ends up carrying Levi to the bed and knotting deep inside him. Levi rides out his orgasm against Erwin's knot, with Erwin making sure to kiss and touch Levi as gently as possible in order to help Levi down from his high.
"Well that was interesting," Levi huffs after a while.
"You regret it?" Erwin asks.
"Not particularly," Levi replies. "I just wanted to talk to you about something before we went and did this."
"You can talk to me now?"
"I don't know whether it's a conversation to be having with your dick in my ass."
"Try me," Erwin says simply.
"Fine," Levi mutters. Might as well go for the direct approach. It's worked well for them so far. "Hanji thinks we should mate."
"Mate? As in like, have a pup?" Erwin asks confused.
Levi sighs. "No. Well, yes, but not in that way. There's more to mating than having a pup. Honestly, I don't fully understand it myself, and you should probably talk to Hanji, but… it's about… symbolically recognising our relationship..."
"I think that sounds like a great idea," Erwin says, before stopping to think. "But why?"
"The clinginess, the heightened libido, the possessiveness… You can't tell me you haven't noticed it."
"Well… yeah… but I thought it was normal?"
"Not really," Levi sighs. "Hanji said that we've formed the emotional connection that mates have, but we haven't formally mated. And we can't, but we can… we can start biting each other's scent glands."
"I'd like that," Erwin groans. "Oh God, I'd love nothing more than to claim you as my mate." Levi can't help but blush. "But is this what you want or what Hanji wants?"
"Well… Hanji wants it, but I do as well. And not just because we're acting like sex-crazed animals, but because you're mine, and I'm yours."
"Then I'd love to mate you, Levi," Erwin murmurs, rubbing his thumb tenderly down Levi's cheek. "We can take tomorrow afternoon off. Go to the cabin. Have some alone time."
The cabin is a small building that Erwin bought off a bankrupt farmer for their first anniversary. They usually use it when Levi needs to go through heat, but they also use it to getaway every now and then. It's positioned about an hour ride away from HQ, and Levi fucking loves the place. It's quiet, clean and it's a nice nesting place for only them.
"Sounds perfect," Levi whispers back, leaning into Erwin touch. He lets his eyes flutter shut, content to let Erwin worship his body with light touches and kisses.
"My dick is still in your ass," Erwin muses teasingly, blowing a raspberry onto his chest.
"You're terrible and I hate you."
Erwin chuckles. "Love you too, Levi."
Erwin and Levi's fingers stay entwined between their horses the entire ride to the cabin, with Erwin leaning over to steal a kiss every now and then and Levi swatting him away playfully.
Levi isn't quite sure how it happens, but once they get to the cabin, they gravitate to the couch and start making out heatedly.
"Stop it," Levi murmurs. "We still have to eat dinner yet."
"Just one more," Erwin says, leaning down to kiss Levi firmly on the lips, licking his tongue into Levi's mouth one last time. "You taste so good."
Levi scowls, pushing Erwin off him and standing up. "We're making dinner. Now."
For the most part, Erwin manages to keep his hands to himself, and by the end of their dinner preparation, Levi is aching for Erwin's touch.
"Okay, fine, you win," Levi says, flinging himself into Erwin arms and burying his head into Erwin's chest. It's almost pathetic how dependent on Erwin he is, but when he feels this safe trapped in Erwin arms, he doesn't seem to care too much anymore.
"That was really nice," Levi murmurs into Erwin's ear as they both finish their dinner.
Levi is sitting comfortably in Erwin's lap, arms wrapped around his body. Every now and then, Erwin will place bits of his own food into Levi's mouth, and even though Levi hates the idea of being hand-fed, he accepts graciously, enjoying the amount of care his Alpha puts into him.
Levi bites Erwin's ear. "I think it's time I finally had my way with you," he whispers, nudging down to Erwin's scent gland, not quite touching it, but hot breath hovering just above.
"Fuck," Erwin bites out. "Do it, Levi."
"Bed first," Levi whispers, legs encircling Erwin's waist, waiting to be picked up.
Erwin grunts, standing up while also holding onto Levi, who mewls at the feeling of being handled by his Alpha. Erwin places Levi on their bed before curling on top of him and bearing his neck.
Levi wonders whether it's usually the Omega who does the biting first. It's probably not, but that's not going to stop him from claiming Erwin before Erwin does it to him.
"Someone's eager," Levi mutters.
"I've been waiting for this for a long time."
Levi's breath is still hot on Erwin's neck. "How long?"
"Since I first met you," Erwin breathes.
"Do you think you could wait a little longer?" Levi hums.
Erwin groans in frustration and Levi chuckles, finally attaching his lips to Erwin's scent gland. He doesn't start biting immediately, but starts sucking hard enough to leave big purple bruises.
"Levi, I-," Erwin stutters, fingers embedded deeply in Levi's back, the feeling overwhelming his mind.
"Shhh," Levi coos, scraping his teeth along the gland.
When Levi finally embeds his teeth in Erwin's scent gland, Erwin all but howls, hands grabbing at any inch of Levi he can find, body taut and limbs trembling. He collapses on top of Levi, who manoeuvres himself to Erwin's side, teeth still attached to Erwin's neck.
Levi can smell the pheromones pouring from Erwin's gland, and it smells delicious. Levi uses his tongue to lick the skin in-between his teeth to try and gain access to more of the scent. It's pungent with the usual lust and arousal, but also has a different hint to it.
One that is like a warning sign for anyone else.
Anyone other than Levi.
Levi slowly detracts his teeth from Erwin's skin, who visibly relaxes in his arms. Levi gives Erwin's gland one last playful nip and Erwin moans.
"What was it like?" Levi asks tentatively.
"It was like-," Erwin has to pause in order to slow his breathing, and Levi cards his fingers through Erwin's hair in affection. "It was like this coil inside of me snapped. At first it was so intense and blinding, but after a while it was really comforting."
Levi bites his lip. He knows that mating with Erwin is something safe - something that we wants more than anything - but right now, he feels anxious as hell. "So I guess it's my turn?"
Erwin's lifts his hand so that his thumb can dislodge Levi's lip from his teeth, before kissing him tenderly. "You don't have to do anything you don't want to," he says, as if he instinctually recognises Levi's anxiety.
"I want to," Levi says defensively. "I'm just… scared."
"Of what?" Erwin asks. "You can talk to me, remember? It's much better to say what you're feeling than to hold it in."
Levi nods – he knows this – but even after so many instances of Levi spilling his secrets to his Alpha, he still gets nervous. "I… I'm afraid to be attached to an Alpha…"
"I'd never forcibly keep you. You have a right to say 'no'."
"I know."
"And I will always stop if you say 'no'."
"I know."
"And you still want this?"
Levi nods, fingers clutching onto Erwin's clothes. "Maybe if we get naked, I might feel at ease."
"Okay," Erwin agrees, shedding both his and Levi's clothes with ease. Levi will never understand how he does it so fast. "Is that better?"
Levi nods again, and leans over to start kissing Erwin again, slowly and sweetly. "I want you to do it," he says, tilting his own head to the side so his gland is on offer to Erwin.
Erwin eyes darken and his head dips into Levi's neck, with Levi using his hands to hold Erwin's head there.
When Erwin's teeth scape the skin of Levi's gland, Levi cries out, his body shivering at the overstimulation.
"Fuck, Erwin," Levi gasps, head tilted back as far as it can go. "Do it, do it, do it."
Erwin's teeth sink fully into the flesh of Levi's gland and his whole body goes stiff. His eyes roll into the back of his head and he can swears he sees stars dancing around his vision as all the tension building in his body snaps and releases.
Levi can feel their affinity for each other climb, as they become connected not only as an Alpha and Omega, but also as mates.
His body slowly climbs down from the high as Erwin releases his skin, sucking small hickeys into his neck. The loss of tension is comforting, but also frustrating, as his whole body lights up with arousal once more.
He needs his Alpha.
"More, Erwin," Levi moans, fingernails digging into Erwin's skin, legs wrapping around Erwin's waist. "I need more."
"Turn around," Erwin orders, voice low and strained. "Ass up." Levi complies, turning onto his stomach and presenting his ass for Erwin.
Erwin slots in behind Levi, reaching out a hand to hold against Levi neck, thumb imprinting onto his scent gland, much like he did yesterday.
"Damn it," Levi gasps, bearing his neck further for Erwin to hold. He bucks his hips up in order to feel more but Erwin isn't having a bar of it. "Fuck."
"Whose Omega are you?" Erwin asks, head bent down and as close to Levi's ear as he can get it.
"Yours. Always yours." Levi mutters.
"Good answer," Erwin replies, grabbing his cock and fucking into Levi with one swift thrust.
"Shit," Levi gasps, back arching at the feeling of Erwin's cock reaching deep inside of him. The angle is perfect, hitting Levi's sweet spot every single time with powerful force that only an Alpha could muster. He buries his face into the sheets and jerks shakily underneath Erwin.
It doesn't take long for them to both climax, Levi into the sheets and Erwin on top of Levi. Erwin holds Levi's hand through his orgasm, helping him down softly despite fucking him roughly into the mattress. When Erwin orgasms, he pulls out just before knotting so that he can bite Levi's scent gland one last time and watch him squirm tiredly underneath him.
"Ugh, that's fucking disgusting Erwin," Levi mutters, surveying his dirtied body covered in bodily fluids.
Erwin rolls his eyes and scoops Levi into his arms, carrying him into the bathroom. He knows Levi doesn't mind the mess as long as he gets a relaxing hot bath out of it.
They spend the rest of the night nuzzling and nipping at each other's scent glands, blissfully content to enjoy each other's company without caring about anything else in the world.
Levi wakes to Erwin placing feather light kisses to his chest, and mumbles incoherently about the time.
"What's that sweetie?" Erwin asks, moving so they're eye to eye.
"I said, 'what's the time?'" Levi answers, knowing that they have to be back at HQ by midday.
"Midmorning," Erwin replies, sweeping Levi's lips up in a sweet kiss. "But don't worry. I've already cleaned up and made breakfast. All you need to do is get dressed, eat and leave."
"You're fucking perfect," Levi groans.
They kiss a few more times before Levi notices Erwin's neck and gasps. "Shit. Look at your neck, Erwin." Levi says, inspecting the dark purple masses of bite marks and bruises. "How the fuck are we going to cover that up?"
"This time, a scarf, probably," Erwin explains. "Hanji also gave me this concealer which will help for tinier bite marks that we make from now on, but it won't be able to cover something like this up."
Levi nods his head, but he can't help but feel depressed at the fact that they have to hide like this. Every single time he wants to mark Erwin, he's going to have to hold back. Just like with everything they do, their jobs have to come first, but deep down Levi doesn't want it this way. If his animal side had anything to say about it, Erwin's marks would be on display for everybody to see.
Erwin can see the slither of apprehension cross Levi's face. "It'll be okay. I know it's going to be hard, but we'll manage. We've made it this far, haven't we?"
"Yeah,"
"Then we'll make it even further. Trust me."
"Okay," Levi says, because trusting Erwin is the one thing he indefinitely knows how to do.
The two dress themselves slowly and eat in peace, enjoying the last of their alone time together, stealing kisses whenever they can. Levi knows that there will probably be many more visits to the cabin from now on, but he'll make the most of the time he has now despite it.
When they get back to HQ, everybody notices their renewed energy. But nobody says anything, of course. Not unless they want to be flayed alive by Squad Leader Hanji.
"I love you," Levi whispers into Erwin's hair in the dead of night. "You've helped me feel again, and I love you for it. Even in your worst moments and darkest days, I'll love you. Even when the whole world is against you, I'll still love you. And one day, we'll destroy the titans and buy a house and have pups and grow old and die together; I promise."
