Chapter Text
Levi can’t fully describe the feeling of freedom he experiences now that he has a mate who can help him manage his heats rather than suppressing them. It has been years since he and Erwin were bonded, but still every time Levi’s heat approaches he gets these overwhelming feelings of gratitude and happiness. Sappy bullshit Levi chalks up to his hormones going haywire and not for the feelings of love he holds deep for his alpha and commander. Never that. Until he is an incoherent babbling mess when the worst of it hits and humanities strongest can’t quite hold his tongue, much to the large blonde’s delight, that is.
Since the world has been going to hell lately, what with Wall Maria falling and teenagers turning into titans, there have been more important things to deal with than Levi’s sex drive and biological needs. So when they finally get a few weeks respite to train up the new recruits, Levi intends to take full advantage of it being close enough to another heat to be able to push him into one if he can get Erwin riled up enough. Which really isn’t going to be very hard. Levi has had to suppress the last three heats, so he knows this one will be intense, which should also help to ease it in early.
Levi knows Erwin will patrol the training grounds in the morning, sizing up the new recruits and inadvertently intimidating them into tripping over their own feet. Hanji has already taken account of the physiologies of the new troops and surprisingly there are three omegas among them with the rest equally beta and alpha. It’s odd that in such a small group there would be that many omegas since though they are not necessarily rare, they have been coveted greatly for the ability to bear children in their desperate world of survival. For years omegas were stored away as though prized possessions rather than human beings, some extreme groups even going so far as to worship them as some sort of fertility gods. Ten years ago you would have never found an omega in any military branch, let alone in the Survey Corps, it was simply not allowed. And while the world is changing for omegas, thanks in large part to Commander Pixis who worked his way up the ranks before shocking everyone when he revealed he was an omega and demanding that peoples views change and proving that omegas can offer much more than just children, it is still hard for people to let go of stigma and tradition. Eighty-five percent of the time Pixis isn’t drinking alcohol from his flask, it is suppressants as he refuses the mere idea of an alpha.
Unintentionally Levi also played a part in the reformation of omegas, having never hidden what he was even in the underground, and certainly not when he was named humanities strongest - despite a personal letter from the king himself suggesting otherwise. Needless to say such powerful, well known figures being omega had a trickle effect on all of the young omegas who dreamed of more than alpha mates and ornate trophy rooms and children on each hip, it gave them hope and drive. But even so, omegas in the Survey Corps is still a bit of a rarity. Before the added three from this new group there are only five others including Levi. This really only concerns Levi so he knows who to keep away from when his heat hits so as not to drag the rest of them into their own. Usually all Levi needs to worry about is keeping clear of alphas but with so many new omegas now he will have to be extra careful.
Just as he assumes, Erwin is prowling around the courtyard watching drills and generally overseeing things. The recruits look nervous in his stoic presence and Levi is inwardly smug at his privy knowledge of just how depraved the seemingly golden boy of the Survey Corps can be. How Levi’s mere scent can bring the powerful man to his knees and pleas from his lips. It’s been far too long since Levi saw those blue eyes glass over with lust over his little omega, ready and willing to do anything Levi may demand of him if only he gets a taste. Levi wants to see it, and now. He is careful though, keeping a safe distance from the other soldiers, but close enough for a mate to be aware. It’s like a shock to Erwin’s system when Levi’s scent hits him and he visibly tenses like he were physically hit by the smaller man though he is easily twenty feet away and nonchalantly resting against a tree outside the empty administrative offices. Levi wears only a thin cotton undershirt and a pair of black slacks - his uniform and gear purposefully absent and unneeded on his very rare day off. The captain can tell Erwin is using all of his self control to keep attention on the recruits and not turn around to see his mate - always a man of duty and priority. Infuriating and respectable, Levi equally loves and hates the blonde for his diligence. He will just have to up the ante.
Levi glances around and sees Mike hurrying about by the side of the stables with a horse before mounting and giving Levi a fleeting look across the training grounds. Levi cocks his head and Mike takes the hint, his heel encouraging his horse to take off in a gallop. Good, that is one less thing Levi has to worry about. Had Erwin and Levi been having personal time together on a regular basis he would have fancied the idea of inviting Mike to their bed again, getting both their heats done and out of the way in one go. But now was not the time to bring in Erwin’s one and only other omega partner - never mated of course. The jealousy would be intense on Levi’s part and there is a good chance he would try to kill their scruffy friend if he felt his mate was giving out more attention to the massive omega than himself - knotted or not. No, Levi needs Erwin all to himself right now. With Mike’s pesky nose gaining distance from them Levi thinks he can risk at least a gander by his fidgeting blonde lover. But it only takes two steps towards the practice grounds before Erwin is turning around and advancing on Levi with bright eyes and an uncontrollable little lick of his top lip. Levi smirks. Erwin immediately crowds up into him, unable to suppress his need to be close, unconsciously covering and protecting his small mate from the others around them and pressing his nose into the top of that black hair with a sigh.
“Levi, what are you doing out here, it’s your day off. And why do you smell so damn good…”
Erwin must be incredibly over stressed if it hasn't even click yet what Levi is doing little to hide. He’s not even wearing his cravat in an attempt to cover up where his scent is the strongest. They apparently both need this - bad.
“I’m not using suppressants.”
It’s a statement that forces a tiny groan from the commander and makes him bite his bottom lip as the meaning kicks in. But the blonde’s voice is still disapproving and concerned when he says his name.
“Levi…”
“Shut up, I don’t want to hear it old man. I have made up my mind and we have the time right now. It will be fine.”
“But -”
“I need it.”
“Okay.”
Erwin curls further into Levi, uncaring for public displays on the Survey Corps grounds, especially when Levi smells like addiction. He says 'okay' again into Levi’s crown as the smaller man loops his deft fingers beneath the 3DM gear straps that curve around his mate’s hips. The blonde speaks again, softly into Levi’s hair.
“But we can’t do it here. Too many young omegas in this bunch and I don’t want to take the chance.”
“I know, I thought we could go to Madame Sowe’s. She will be discreet and she owes us.”
“Good, I will send off that we will need a room asap and finish some things up here with the recruit orientation.”
“I’ll talk to Hanj and get what we need.”
Necessities out of the way, Levi yanks on the straps hard enough to make Erwin lean over so the smaller man can get his face right in the crook of the blonde’s neck. Levi mouths up the sensitive skin and all the way to his ear where he fans warm breath that makes Erwin shudder and inhale sharply.
“I need your cock, Erwin, and you are going to give it to me in every way that I demand and every way that you have dreamed. I’m going to fuck you so hard even your knot won’t stay inside me.”
And with that Levi pulls away and gives his mate a little shove as he turns back to go inside again with barely another glance at Erwin's wide, hungry eyes. Levi calls over his shoulder with a dismissive wave of his hand.
“You know where to find me.”
Levi commends the rigorous amount of self restraint Erwin must use to turn away from his mate on the brink of a heat. A feat that speaks of the man’s devotion, but Levi will have his undivided attention for the next few days and he intends to make good use of it. Just as Levi reaches the door he hears Gunther call out.
“Commander are you okay? Everything alright? You look kind of funny.”
Levi smiles to himself and doesn't hear Erwin’s response as he enters the offices on his way to find Hanji. He wonders how long it will take his mate to give up on his duties and find Levi. How desperate he will be for Levi by then, his sweet scent surely stuck in the back of his throat goading at his primal instincts until he snaps. Levi can’t wait.
