Comfort
You come home from work, it had been pretty exhausting and you hope that Katsuki is up for a little bit of cuddling. Since his heat is coming up, he requested vacation time, his boss from the agency doesn’t know that he is an omega, and since Katsuki suppresses his heat, except for four times per year, he manages it quite well to conceal his secondary gender.
The key rustles in your hand before you open the door with it, but as soon as you enter your apartment, you can smell the distressed scent of your mate from your den.
“Katsuki? Is everything okay?” You ask while you put your stuff away, you hurry to get to him.
There are faint whining noises from the den and you make your way over. Your heart clenches when you hear them. In a hurry you open the door and you find it empty on the first look. Quickly you look around, the nest is empty but he is clearly in here, that’s why you turn to the closet and walk closer.
“Kats? What’s wrong?” You question gently, while knocking on the door.
He hisses at you for a moment before he slowly opens the it, he sits buried deep inside the closet, surrounded by his and your pieces of clothing. He usually only goes there when he is really, really upset.
You kneel down to be at eye level with him. “Hey, babe, what’s wrong?” You try to stay calm, even though you are enraged by the thought that someone has hurt your mate.
Katsuki jumps out of the closet to hug you, he buries his face on the crook of your neck, absorbing your calming scent. “They found out!” he wails.
You gasp and wrap your arms around him. “That you are Omega?” You can sense that Katsuki is close to his heat, because of that he is more emotional than usual, since his hormones work in overdrive. “What happened?”
While it is not uncommon these days that Omegas are heroes, most of society still thinks of them as inferior, they will prefer bad Alpha heroes over good Omega heroes any day. They still think Omegas were too weak to do the job, that’s why Katsuki decided to pose as a Beta for so long.
“Yes! I was there to give my application for vacation like usual, but I bumped into this one douche bag, he doesn’t like me and I don’t know what happened but he noticed my scent patches and to fuck with me he pulled it off, asking why my ‘Beta ass’ wears fucking scent patches, they could smell that I am Omega and my boss was furious that I hid it from him! They will look down on me now! No one will take me serious! Especially Alpha villains will think, that they have an easy game with me!”
Your heart clenches when you see him like this, his normally sweet scent is sour with distress. “Come here, baby. You will show them, how good you are! You managed to become the Top 6 Hero in such a short time, even though you are an Omega, posing as Beta. Anyone who underestimates you now, thinking they have an easy game, is an abso-fucking-lutely idiot!”
You pull him out of the closet completely and lift him up, before you carry him towards the bed. Carefully, you place him on the mattress, before climbing in yourself. He waits until you find your position before he snuggles closer to you.
“But you know the people, they are entitled fuckers who still think that Omegas belong into the kitchen, or into an Alpha’s bedroom as a fuck toy.”
“They are absolute idiots, like I said. And I have no doubt that you will absolutely destroy their views! Even though they know now that you are Omega, you will shatter all their doubts with your explosions! You are the Great Explosion Murder God Dynamight! Everyone who thinks you are weaker now, all of a sudden, is fucking dumb!” You hug him tightly and you start to rumble to soothe him.
He snuggles against the crook of your neck and you start to scent him. After a while he begins to purr, too. “You’re the fucking greatest, most amazing hero of all time, You made it as an Omega into the Top 10, not many get this far. This should prove, that you are not a weakling!”
“But you know how people are, sometimes I had other Alphas with me, they will say that they did all the work and shit. People are fucking judgmental, it sucks so much!”
You pet his hair, the rumbling intensifies. “Then kick their fucking stupid asses, you have my permission.” You smile at him and plant some kisses on his forehead. His sour scent slowly turns sweeter again as he calms down.
“Yeah, I could really do that …” He smiles and leans up to you to kiss you on the mouth.
“You’re my damn amazing mate, no matter your secondary gender. You will always be my absolute best hero. None of the others come even close to you and the fact that you are Omega and are still better than most of the Alphas should prove that secondary genders don’t matter.” You press more kisses on his face.
He purrs and leans back so you can kiss him on the mouth. “I love you, Katsuki.”
“And I love you. And you are damn right, I am amazing! No doubts!”
“My talking! You’re the fucking best!” He chuckles and suddenly he moves to sit on your lap. He leans over and his body basically melts into yours. He wraps his arms around your neck. “You have no idea how lucky I am to have someone as amazing as you as my mate.”
Katsuki purrs happily, it’s the loveliest sound in your ears. His scent is finally sweet again. The small omega rubs himself against you, to scent you completely. “I should be the one saying that. I know that I can be an asshole at some times, especially during our school time. That you chose me, out of all the others is unbelievable. I still have no idea why you did that, but I am grateful that it was me.”
You rumble and your hands wander his back up and down. “Like I said, you were always the most amazing person in the room. I instantly knew that it had to be you or no one.”
Katsuki’s cheeks are blushed and he purrs even stronger. “You know, when you started courting me, I thought you were an idiot for doing so. Who in his right mind would date someone like me?”
“Maybe I am not right in my mind then?” You tilt your head and look at him.
He chuckles. “Yeah, that might be true.” He lets out some happy chirping sounds. It’s music to your ears. You continue to scent him, while a deep rumble comes out of your chest.
“Promise me that you won’t take their bullshit talk too personal. The fact that they know now is irrelevant. You are not less valuable.”
“Yeah, I’ll try my best.” He has a sad smile on his face. “Where you mad, when I came out as Omega to you, and not as Beta.” Even in school Katsuki had presented himself as a Beta, you had started courting him under the impression he was one.
“Absolutely not! Kats, it never mattered to me, what secondary gender you had. I fell in love with your personality, not your genitals.”
He smiles happily at you and snuggles even closer, if that’s even possible. “Thanks! I was always insecure about my secondary gender. It wasn’t easy for me to accept it.” He looks slightly sad. “I always thought I would present as Alpha, every sign suggested I would, but then nope! It had to be Omega …”
“You are beautiful, baby, I love you, no matter what.” You kiss him again, then you pull him closer to your body and you flip the two of you around. You intertwine your fingers with his. “You mean so much to me … you have no idea, Katsuki.”
“And you mean the world to me! You are my world, my big and strong Alpha.” He purrs.
“My even stronger and more amazing Omega!”
“Let’s always stay together! Nothing will ever separate us!”
“Yes, always and forever!”
You stay cuddled up in the warm nest for much, much longer. You kiss more, his purring and your rumbling are echoing through the room. It’s very peaceful and you enjoy the physical contact with your lover.
----- (optional NSFW part) -----
Your tongues dance around each other, Katsuki’s scent gets so spicy in the last couple of minutes. You notices that he slips into heat, he clutches onto you as if his life depends on your proximity. He winces and tries to undress himself, but your weight makes this task impossible.
You chuckle and lift your body up a little bit, with smooth movements you undress him and yourself before you pull him closer and flip you both around. He sits astride on top of you now, you lean back on the mattress and cross your arms behind your head, you wiggle your eyebrows as a sign that he can do what he wants.
Katsuki chirps happily and he leans down again to kiss you, his hands wander over your massive chest, and he moves slightly back, he rubs himself on your dick and you get hard in no time.
Your cute omegan mate really enjoys it, when you let him have the control during sex, he slips down and you enter his vagina, he moans when you fill him out.
He moves rhythmic on your dick, your hands trail up his thighs over his ass and up his body, he leans his head back, his eyes are closed while he moves on top of you. His breathing gets faster. “My Alpha, make me forget everyone but you, please!” he murmurs.
“Yes, my beautiful, strong, intelligent, impressive, absolutely breathtaking Omega” you murmur, you sit up and pull him closer, he fastens the rhythm, now wrapping his arms around your neck. You can feel how Katsuki’s slick is flowing out of his cunt and ass, it covers your entire bottom by now and it’s the greatest feeling. You plant some kisses on his throat, then licking over it, using your spines to playfully scratch him.
He mewls when he gets closer to orgasm, you start to move on your own now, but within Katsuki’s rhythm, he lets out even more moans when he comes, you manage to time your orgasm with his and you let your knot swell, locking yourself inside of Katsuki.
Your beautiful omegan mate bites down on his lips, when you slip your fingers inside of his asshole, his face is wonderfully blushed and he buries it on the crook of your neck. “So much!” he moans.
A low chuckle escapes your lips and you remove your fingers out of his ass. Your entire hand is covered in slick, it has a thick consistency, it drips down in between your fingers. Still panting, Katsuki turns his head, he blushes when he sees, that you lick your fingers. The slick tastes incredibly sweet, it has much of his own scent of caramel and burnt sugar in it.
“You like my slick?” He asks.
“I love it” you lean over to French kiss him, so he can taste himself.
After that you carefully move to lay down together, you have to wait until the knot deflates again. Katsuki snuggles closer to you, purring heavily in the process.
“I love you so much …” He murmurs sleepily.
“And I love you, you’re my world.” You answer. You stay interlocked for quite some time, he eventually falls asleep before your knot is deflated. You make sure to stay awake until you can pull out. You plant some more kisses on his forehead, yeah, you were with your one true love, and he was feeling better again, that was all that mattered to you.
