Chapter Text
Bakugou spends the next three days in the infirmary. The poor pup was exhausted from lack of sleep and food. Shouta makes sure to visit him when he can, mostly during lunch and the few classes he has free.
Ever the overachiever, Katsuki is able to stay awake long enough to eat a full meal by the second day. He quickly regains energy, and by the third day, Recovery Girl allows him to leave.
Shouta is happy to see him getting better. There are still the lingering symptoms of sickness, but he’s out of the danger zone for now.
“You better make sure to take this twice a day.” Recovery Girl demands. “You cannot skip it even once, or you won’t be healthy enough when your heat arrives. It’s only four days, so if I find out you skipped a dose-”
“Tch.” Shouta can tell Bakugou wants to roll his eyes. His respect for Recovery Girl is probably the only thing saving him from getting smacked with her cane. “I will.”
“Good. Now get out and don’t come back for a long while, you hear! You hero students, always getting yourselves into trouble.” She shakes her head, muttering to herself as a student from 1-B walks in with a black eye.
Bakugou is quick to speed out of the infirmary, and Shouta follows him. She may have held back because Bakugou was sick, but there would be no saving him from a stern talking to now. He’s sure she would find a reason to bring him into it, too, and he has already been on the receiving end of her cane one too many times.
Once they are halfway down the hallway, Bakugou’s pace slows. “So… you said you weren’t going to touch me and all during my heat… how the fuck is that going to help? Doesn’t an Omega need a...” He looks around the hallway, avoiding Shouta’s eyes. “Knot.”
Shouta can’t help the amusement he feels when he sees the soft blush on the tips of Bakugou’s ears. He understands, though. It was easy for Bakugou to avoid the intimate details when he was telling him what happened. There’s no way to avoid it now when they are going to be spending his heat together. Shouta is going to see sides of Bakugou that he never thought he would.
“There’s more to it than that, but yes, you might need a knot during your heat. It doesn’t have to be mine, though. There are plenty of toys that can simulate that if it’s necessary. On that note, can you tell me what it’s like for you? Some Omegas who are feral may be unable to feel horny, and others still feel it.”
Bakugou tilts his head, thinking. “...it comes and goes. Sometimes I’m focused on staying alert. Or I’ll get horny enough that it starts to ache really badly, and then I’ll panic. Eventually it will go away because I’m too busy trying to protect myself.”
Shouta nods. “Do you have anything to help keep the ache away?”
Bakugou shakes his head. “I left all of it at home… I couldn’t use them after…” His scent sours a little.
“That’s okay,” Shouta says, brushing his wrist against Bakugou’s. The sour scent of fear quickly dissipates, and Bakugou unconsciously moves closer. “We can get you some new ones. UA provides heat and rut aids. I’ll let you pick out what you want.”
Bakugou nods. “What about…”
“Yes?”
“Nesting materials. I need your scent.” Bakugou looks him in the eye. “I’ve got to be surrounded by your scent if you’re gonna be in my nest.”
“Of course. You can come by the teachers' dorm anytime to pick out something of mine to place in your nest.”
“Now?”
Shouta blinks. “You don’t want to go back to class?”
Bakugou rolls his eyes. “Tch. There’s no fucking point. There’s only one period left, and it isn’t even heroics training.”
“Alright, we can go now.” Shouta changes their direction, leading Bakugou to the teachers' dorms. He stays behind him, shoulders hunched and hands stuffed in his pocket. The common room is thankfully empty since school is still in session, so he’s able to lead Bakugou to his dorm without fuss. When they arrive, he opens the door for Bakugou, watching him look around his space with interest.
Shouta was never one to have a lot of belongings, so it’s not crowded like Mic's dorm, but it’s cozy. There’s a sufficient amount of furniture and a few pictures on the wall here and there, which he thinks is perfectly acceptable and does not make his place feel soulless. Yes, he’s still salty that Midnight said that.
“Damn.” Bakugou whistles. “It’s like a whole ass apartment.”
“A lot of the teachers refused to live in a dorm like the students. Plus, since we’re heroes, it’s easier for everyone to have their own bathroom and kitchen.”
“Lucky bastards,” Bakugou grumbles. He stays with Shouta, surprisingly respectful. He can tell his student wants to sniff around and check out his dorm, but he waits by his side, following his lead as he slips off his shoes.
“So what types of scented items do you like in your nest?” Shouta asks.
Bakugou shrugs, reluctantly moving his eyes away from the new scenery to look him in the eye. “I don’t usually know until I find it. It’s hard to find something that I like enough to put in my nest.”
Ah, he’s a picky Omega. It makes sense. He once heard Bakugou talking to his friends about how ‘you need to treat yourself like the best if you want to be the best’. It’s a good mindset to have. “Alright, I can show you around if you want? To see if anything catches your eye?”
Bakugou nods. He follows behind Shouta like a lost duckling as he’s led to the other rooms. Shouta lets him look around, watching him consider each item with a seriousness he usually sees in battle.
He hides a smile in his capture weapon, watching Bakugou tilt his head and feel the material of one of Shouta’s shirts. His mouth is slightly open as he takes deep breaths to scent the air, his eyes squinting in consideration before he shakes his head and moves on.
The few blankets in his living room didn’t meet Bakugou’s standards, and none of the clean shirts he forgot to take out of the dryer this morning did either, so Shouta makes his way to his bedroom. “Are you comfortable looking inside my den for something you would like?” He asks before he opens the door.
“Should be asking you that.” Bakugou crosses his arms. Shouta can tell how badly he wants to see what’s inside, though. It’s not everyday you get to take a tour around your teachers dorm. He opens the door, letting Bakugou inside.
Shouta can tell immediately that he is more interested in what’s in here. He takes his time, looking at each blanket on his bed. “This shit is good quality.” He mumbles, all but crawling on the bed as he feels each one. Shouta holds back a rumble, not wanting Bakugou to know how affected he is right now.
The scent of heat lingers on him, and knowing that he’s going to be picking a scented item of his is enough to make Shouta’s Alphan instincts go wild. He wants to cover Bakugou head to toe in his clothes and his scent. To cuddle him close and keep him protected.
While he can feel the attraction, he knows that nothing of the sort will be happening any time soon, and that’s fine with him. He would never want to hurt Bakugou or make him uncomfortable.
Bakugou shakes his head and sighs before moving over to Shouta’s closet. He looks over his shoulder, blinking at him, and Shouta nods in permission. When he opens the doors, a wave of Shouta’s scent blankets the room. It doesn’t bother Bakugou at all as he looks through every item of clothing. When he once again finds nothing, he moves over to the dressers.
Eventually, Bakugou makes his way back in front of him, a frustrated tick in his brow. He lightly sniffs the air, his pupils dilating. Shouta watches Bakugou move closer, his interest suddenly shifting to Shouta’s capture weapon.
Bakugou feels the material and brings it up to his nose, taking a deep whiff of his scent before nodding. “This.”
“My capture weapon?”
“Yeah. It smells the most like you. It’s long enough that I’ll be able to wrap it around my nest a few times, too.” Bakugou tugs at it lightly. “Can I take it?”
“Of course.” Shouta lifts it up and plops it around Bakugou’s neck.
Bakugou snorts. “You look weird as fuck without it.”
Shouta shrugs, walking out of his room to the mostly empty room across the hallway. There is a bed and a dresser, but that’s all. “Are you okay with having your heat here? It doesn’t necessarily have to be this room, but I think it will work best. This one has a scent-neutralizing fan, which will help greatly during your heat.”
“Why not my dorm?” Bakugou asks skeptically.
“Well, if you’re here, it will be a lot easier for me to make you food and bathe you if necessary. Plus, there will be absolutely no one to bother you.” Bakugou immediately agrees as soon as Shouta says the last part, just like he knew he would.
“Great. I want to make this as easy and comfortable as possible for you. You can bring anything you need over and spend some time here before your heat. You can even sleep here if you want. I don’t mind. I can scent you, too, if that’s something you need.”
Bakugou raises a brow. “Damn, really?”
“Absolutely. I want you to get better.” He runs his hand through Bakugou’s hair, rumbling when his student leans into the contact. “We only have three days to prepare, unfortunately, so if there’s anything you need, please tell me as soon as possible.”
“Okay… “ Bakugou reluctantly backs away, burying his hands in Shouta’s capture weapon. “I need to go back to my dorm to get my nesting materials, and then I’ll bring them over.“ He pulls it over his head, handing it back to Shouta.
“I don’t want your scent wearing off,” Bakugou says when Shouta gives him a confused look. “I’ll be back soon.”
Shouta smirks, shaking his head to himself as Bakugou waits for him to reposition his capture weapon around his neck before leaving to gather his nesting materials. Once Bakugou is gone, he absentmindedly rubs it against his neck, making sure his scent is saturated.
He grabs Midoriya’s notebook from the coffee table and heads to the kitchen. He has read through it a few times since it was given to him, but he wants to make sure he has taken in every detail.
Midoriya is one of his most observant students, and he has managed to get closer to Bakugou than Shouta has. He’s thorough, too. There’s everything from the very first heat Bakugou had at UA to the day he collapsed in class.
There are notes about Bakugou’s scent, and what subtle shifts might mean, how he likes to nest, vivid details about how Bakugou acts when feral, and a long list of ways to take care of him during his heat.
Shouta is very knowledgeable about helping traumatized Omegas, but he has to admit there are a few points that even he didn’t know. You would think that meant they would know better than to have done what they did during Bakugou’s last heat…
He flips to the back of the notebook, skimming through the list of Bakugou’s favorite snacks and foods. A lot of it is spicy, which is unfortunate since Recovery Girl gave him strict instructions not to eat spicy food so it won’t upset his stomach.
Shouta will still prep some meals for him. Bakugou will probably be too out of it to complain anyway. Plus, the cum will help.
And that’s another thing. Shouta’s cum. One of the most beneficial ways to calm an Omega down is to feed them cum. It’s especially helpful for a feral Omega. The hard part is giving his cum to Bakugou. Simply adding it to his food will be a good workaround for now, since anything sexual is strictly off the table for now.
Shouta sets the notebook to the side, grabbing the ingredients he needs for a simple curry. He makes sure to add a decent amount of seasoning since Bakugou can’t have his favorite spices. He’s halfway done by the time there’s a knock on his door.
“Come in.” He says, and Bakugou walks in with a bag that’s almost half the size of himself.
Bakugou pauses, his eyes going to the pot on the stove. “You can cook?”
Shouta frowns, a little insulted by the surprise on Bakugou’s face. “Yes, I can. Most heroes need to know how to cook so we can get the nutrients we need for hero work.”
Bakugou scoffs, continuing his trek to Shouta’s guest room. “Tell that to your fucking students. Dunce Face could burn water.”
“That’s why there’s a mandatory nutrition and cooking class in the second year. It’s unfortunately very common that hero students are useless when it comes to feeding themselves.”
Bakugou cackles, coming back out of the room. “And what does that say about you? You’re always eating those jelly packets and drinking gallons of coffee.”
“The jelly packs are filled with vitamins, and the coffee gives me my will to live.”
Bakugou snorts, an amused smile on his face.
Shouta gives him one of his own before focusing on the curry. “Why don’t you set up your nest? The curry will be done in a bit.”
“Okay, but first hand over the scarf, Old Man.” Shouta chuckles silently, pulling the scarf off and handing it to him. He pretends he doesn’t see the way Bakugou stuffs his face in it as he walks away.
About ten minutes later, the curry is done. He grabs two bowls, scooping a generous portion of rice into each before splitting the curry between them. Then he heads to the guest room, pushes the door open with his foot, and stands in the doorway when he sees Bakugou is still making his nest. He doesn’t want to get in the way of his work.
He silently watches, his lips twitching. Bakugou, of course, treats making his nest as seriously as he did when picking the perfect scented item. He’s thorough, rearranging the blankets and pillows if even one thing is out of place. He smells each item before he adds it, sometimes disregarding it completely.
He walks around the bed, examining it from every angle, rubbing his wrist into the fabric at times. Eventually, he stands back, squinting his eyes at it for a moment before nodding. Bakugou turns, and when he notices him, he lets out a welcoming chirp. He immediately realizes what he did and blushes, clearing his throat. “Fucking finally.”
Shouta hands him his bowl. He takes it, muttering a quick, “Thanks,” before heading back to his nest. He isn’t careful as he climbs in, but the sides are so reinforced that they don’t move. “Well? Get in.” Bakugou says when Shouta doesn’t move.
Shouta finally walks forward, taking the spot in front of him. He sees Bakugou looking at him from the corner of his eye, and Shouta looks up, Bakugou’s eyes quickly dart away. “How's the nest?” He asks, most likely trying to seem casual.
“It’s perfect.” Shouta quickly reassures and is surprised at how genuine the praise feels. He isn’t simply appeasing an Omega close to heat, but making an effort to connect with him.
“Good,” Bakugou smirks to himself, unconsciously letting out a happy scent.
Shouta subtly takes a deep breath through his nose, the scent of happy Omega making him feel at ease. The closer an Omega is to heat, the harder it is for them to hide their scent and reactions. Shouta’s always found it cute, and it makes his protective instincts go haywire.
Bakugou takes a bite of his food and nods. “Not bad. I’m surprised.”
Shouta rolls his eyes. “Did you think it would taste bad?”
“...a little.”
Shouta’s jaw drops in offense, and Bakugou snickers. “Is this how you treat everyone who cooks for you?”
“Yep.” Bakugou smiles so wide that it reveals his dimples. “Just because you’re helping me doesn’t mean you get special treatment.”
“Whatever.” Shouta's grumbles are mostly for show. He isn’t truly upset. He’s glad to know that nothing will change between them because of his heat. “So, about your heat. I want you to know that one of the most effective ways to calm you down would be to-”
“Feed me your cum.” Bakugou blurts. “I know.”
“Okay…” Shouta scrutinizes the slightly embarrassed look on Bakugou’s face. “Are you okay with that?”
“Fuck… I guess so. I didn’t let Deku do that shit because it’s fucking disgusting, but… I feel like it’s okay if it’s you.”
Okay, Shouta’s not going to look too far into that. He squeezes his thigh, trying to rein in his scent. The preheat is getting to them, he knows. He’s always felt affection for his students, and he knows the pheromones from a heat or rut can make you feel things you don’t usually feel. Mating pheromones are tricky, so Shouta needs to wait.
He can examine these feelings afterward, when he knows they will be clear headed.
“Alright, I’ll do that, then. If we can keep you calm from the start, then maybe we can prevent you from going feral at all. But that’s wishful thinking.”
Bakugou nods, stuffing a spoonful of curry into his mouth. His cheeks bulge, and Shouta thinks he looks like a cute squirrel.
…
A squirrel, really? He needs to get a hold on this because if he continues to describe Bakugou’s likeness to cute animals, he may go insane.
“Call me Katsuki. You know, during. I don’t want you calling me Bakugou while you’re balls deep inside me.”
Shouta chokes. He covers his mouth with his fist, coughing so hard his eyes water. Bakugou watches him with a smug smirk. “Fuck you.” Shouta wheezes. When he finally manages to get a handle on his coughing, he takes a moment to breathe.
“You want that?” He asks.
Bakugou shrugs. “If we can. I don’t know if I’ll be calm enough, but I also know if I get horny enough, I'll start to cramp up. If I'm in pain then I’m going to panic.”
Shouta nods slowly. “If you start to cramp up, we can try. I’m not going to push it, though. I’ll still help you through it, but if you’re scared, I’m not going to knot you. We can use a toy instead.”
Bakugou sighs. “Fine.”
They start to eat again. They don’t talk, but the silence is warm. Shouta likes it.
▪︎~~~~◇~~◇~~♡~~◇~~◇~~~~▪︎
Bakugou stays over that night. In the morning, Shouta feels more at home than he ever has in this dorm. When he wakes, Bakugou yells at him about his sleep schedule, all while sliding a plate full of eggs, sausage, and tofu toward him.
Bakugou’s presence makes it feel less lonely. It also reminds him of how long it’s been since he let someone into his life like this. He hadn’t noticed how alone he felt until now.
After school is over, Shouta heads back to his dorm. He’s surprised to find Bakugou knocking on his door later, holding a bag of clothes.
“You said I could spend time here,” Bakugou says in explanation, walking in like he owns the place, sliding their wrists together when he passes by. “My heats in three days, which only leaves two for me to get used to this place. I’m always out of it the day before my heat, so that day doesn’t count.” He goes straight to the guest room
“...alright,” Shouta says, accepting it. Who is he to deny an Omega this close to heat? He knows how temperamental Bakugou is, and after seeing him snap at Kaminari that one time, he knows not to push his buttons.
He turns his attention back to the papers in front of him, but he doesn’t actually see what’s written. “Katsuki.” He whispers, taking in the feeling. He quite likes the way his name slips off his tongue.
Later. He’ll deal with it later.
▪︎~~~~◇~~◇~~♡~~◇~~◇~~~~▪︎
Eventually, the day of Katsuki’s heat arrives. As much as Shouta had prepared, he was still a little surprised when he went to check on Katsuki, only to be met with a fierce growl. “I’m coming in.” He announces softly, unperturbed by the growl he gets in return.
He cracks the door open, slowly sliding into the room, the scent of heat thick in the air. The lights are off, but the slight cracks in the blinds shine light on the bed. Katsuki’s nest is rumpled but still firm thanks to Shouta’s capture weapon.
Katsuki is in the middle of it, his eyes peeking over the side, almost glowing. He growls again.
Shouta smiles, making sure every movement is slow enough that it doesn’t set Katsuki off. He holds up a small container for Katsuki to see. “Hi, pup. I’m going to get close now, okay? I brought you food.” He hopes Katsuki will be able to eat. The small egg bites should be small enough for now. He had made them just a few minutes ago, so they will be warm for him.
He takes a step forward before waiting a moment. When Katsuki doesn’t move, he repeats the movement, slowly inching forward. He makes it about halfway before Katsuki snaps his teeth at him threateningly.
Shouta pauses, letting out a rumble. “It’s okay, I’m not going to hurt you.” He pumps out calming pheromones, waiting for Katsuki’s growls to stop before he steps forward again. Suddenly, Katsuki jumps out of his nest. “Fuck OFF HEDORO!” He screams with so much fury that Shouta is frozen.
Hedoro.
Shouta’s chest tightens, and he barely manages to stop his scent from showing how angry he is. Katsuki knows the name of the man who did this to him. God, he can’t wait to fucking hunt him down and rip him apart.
He shakes his head, focusing on Katsuki, who is rushing towards him, alarmingly close to setting off a blast right in his face. Shouta activates his quirk at the last second and holds out an arm to catch him when he falls from the shock.
He hauls him over his shoulder and deposits him back in his nest, ignoring the feeling of Katsuki’s nails digging into him. He sits on the small section of the bed that isn’t covered in blankets, setting the container on his lap.
His other hand is on Katsuki’s stomach, not pinning or constricting, just holding. Katsuki hisses and growls, scratching at his arm, but he stays steady. When he tries to activate his quirk again, Shouta flashes his own in response. “None of that.” He says softly, but his tone is firm.
Katsuki stops fighting for a moment, panting. He stares at him in fury, looking like a kitten that has just been reprimanded. “I’m not here to hurt you, Katsuki.” His student twitches at the use of his name, snapping his teeth at him again.
“You really are too cute, Sweetheart.” The pet name slips off his tongue all too easily, like he was born to say it. He ignores the thought for now, telling himself that it’s only natural for him to use pet names to calm down an angry Omega.
“Do you want to eat?” Shouta asks, cracking open the container on his lap. Katsuki’s eyes flit between it and Shouta, his nose twitching as he smells the food. “Can you eat by yourself?” He asks, holding it up.
Katsuki snatches it out of his hands, backing into a corner of his nest. He brings his knees to his chest, looking at Shouta distrustfully. He only smiles, watching fondly as Katsuki brings one of the egg bites to his mouth and chews.
He stares at Shouta intently, making sure he doesn’t move. There’s a small but continuous growl in the back of his throat, and every time he chews it gets louder.
Shouta swears he melts. He knows it’s supposed to be threatening, but it’s so sweet. How could someone hurt him?
“Die.” Katsuki spits out venomously, like he can read Shouta’s mind.
“I don’t think I will. Who else will take care of you, hm?”
Katsuki’s shoulders slowly settle, and Shouta watches as some awareness comes back. He’s still feral, but the cum he put inside the egg bites did its job in calming him. “Are you doing okay, Katsuki?”
Katsuki growls.
“Yeah, yeah.” Shouta stands, reaching a hand out. He moves slowly, but Katsuki still bites his arm. He doesn’t react, waiting for him to grab his wrist so he can swiftly slide their scent glands together.
Katsuki pauses, his jaw clenching down on Shouta’s arm. He looks like he’s trying to process what happened, and the way his nose twitches as he scents the air is adorable.
“You don’t seem as volatile as you did your first heat. Is that because it’s only the beginning, or are you going soft, kid?” Shouta teases. Katsuki growls, shaking his head and trying to whip Shouta’s arm around like a chew toy.
Shouta watches him with a fond smile. He knows it's only the beginning. Katsuki is still aware enough to know he’s not in danger. It would be beneficial if Shouta could keep him from falling further into his instincts, but he will make sure he’s prepared just in case.
▪︎~~~~◇~~◇~~♡~~◇~~◇~~~~▪︎
The first day goes over pretty well, thankfully. Katsuki isn’t all that out of it, and while he does use Shouta as a chew toy for most of it, he isn’t trying to blast his face off, so he takes it as a win.
Even so, the constant vigilance and fighting takes its toll on him, and as soon as the sun goes down, he’s out like a light. Shouta manages a light doze after a while, sitting just outside the nest.
He isn’t sure how long it has been before he’s jolted awake by a whimper. His eyes fly open, his attention going to the sleeping Omega. Katsuki’s twitching, little growls echoing throughout the room.
“Off…” He slurs. The sour smell of fear reaches Shouta’s nose, and he’s quick to crawl into Katsuki’s nest, resting a hand on his shoulder.
Katsuki’s eyes fly open, and his hand comes up, hot explosions immediately sparking to life from his palms. “GET OFF OF ME!” He roars. Shouta dodges, but Katsuki’s battle experience allows him to account for it.
He attacks Shouts like his life depends on it, and in his mind, it probably does. He screams and hisses, scratching at him. Shouta tries his best to stay on defense, mainly dodging and cancelling Katsuki’s quirk when he gets dangerously close to hurting either of them.
When tears well in Katsuki’s eyes, he freezes. Katsuki’s screams delve into incomprehensible animal noises, the tears leaking down his cheeks.
Shouta grabs his shoulders and wraps his arms around his waist. Katsuki’s hands beat against his back, his body trying to thrash. Shouta winces, but pumps out a calming scent. Eventually, Katsuki’s struggle weakens, and he whimpers, small sobs escaping him. “Shh.” Shouta rubs his hand up and down Katsuki’s back. “It’s okay, you’re okay. I’ve got you.”
He’s still scared, probably downright terrified from whatever dream he had. Shouta wishes he could help him, but he can’t fight a dream. The only thing he can do is comfort him until he falls asleep again.
He watches his chest rise and fall, his face so peaceful that it makes Shouta’s heart skip a beat. He wishes he could take on Katsuki’s problems. He doesn’t deserve to carry this burden when he’s still so young.
He runs his hand through Katsuki’s hair, smiling at the happy noise he lets out in his sleep.
▪︎~~~~◇~~◇~~♡~~◇~~◇~~~~▪︎
Katsuki wakes up two more times after that. Each time he’s screaming. Shouta catches a few words sometimes, and he manages to get a name.
Hedoro Viran. In the small moment of peace he gets while Katsuki is asleep again, he sends the name off to Tsukauchi before silencing his phone again. He will have to ask Katsuki about the name after his heat.
Katsuki twitches, a distressed keen building deep in his throat. Shouta throws his phone out of the nest, immediately going to comfort him. This time, Katsuki simply flutters his eyes open. He stares at Shouta, his face blank.
“M’ sorry.” He mutters.
“Sorry? For what?” Shouta asks.
“M’ being bad… hurting you… don’t want to hurt you.”
“Fear makes us do things we wouldn’t usually do. It’s only natural to protect yourself when you perceive a threat.”
“I bit you… fought back so hard… Hedoro didn’t like that. Omega’s aren’t supposed to fight back.”
Shouta growls before he can stop it. “Hedoro can go straight to fucking hell. Don’t listen to what he said.”
Katsuki blinks, surprised.
“Omegas can fight back, they can revoke consent, and they can bite an Alpha’s head off for even looking at them the wrong way. Hedoro took what wasn't his, and you were completely in your right to fight back.”
“Okay… m'still sorry for hurting you.”
“I don't mind it. You can bite or scratch me if that's what makes you feel safe. Hell, kick me if you need to deal with how scared you are. And at the end, when you’re too tired to do anything more, I’ll still be here. I’ll take it all for you. All I want to do is take care of you, and if I walk out of this with a few new scars, I’ll be happy because I know it was for a good cause.”
Katsuki sniffles, nodding slowly. His eyes slip closed. Shouta watches his chest move, each breath lulling him further into sleep.
▪︎~~~~◇~~◇~~♡~~◇~~◇~~~~▪︎
Shouta has to comfort Katsuki three more times that night. They are both running on a few hours of sleep by the time the sun rises, but Shouta is more than used to functioning on little sleep. Katsuki, however, is not.
His eyes slip shut every few minutes before snapping back open and shooting over to Shouta, who has made sure not to move so he won’t set him off. At one point, he’s dead asleep, so Shouta takes the chance to make some food for them.
He decides on miso again, even though he made it for Bakugou the other day. He probably won’t be too mad. Shouta bets he won’t even remember that he had it recently.
The whole time he’s cooking, he’s listening for movement from the guest room. He left the door open in case he needed to run over to tell Katsuki what he was doing. By the time he’s done, his cock is hard as a rock.
As soon as the miso is in the bowl, he’s sliding down his sweats and pulling out his cock. He was already leaking at the thought of Katsuki eating his cum, and as soon as he gets his hand around himself, he’s embarrassingly close. It only takes a few strokes before he’s cumming.
He groans, watching through lidded eyes as his cum coats the curry. Once he’s done, he tucks himself back into his sweats and sighs. This is probably the only thing keeping him sane. Katsuki’s still letting off mating pheromones even when scared. Shouta would never do anything Katsuki didn’t like, but his body still gets hard from the scent.
He can live with blue balls; there are definitely worse things that he could go through. He’s glad he can still sate his instincts, though.
Shouta eats his miso, taking a moment to savor it since he hasn’t heard Katsuki wake up yet. The poor pup. He’s already exhausted, and it’s only been a day.
When he hears shuffling, he walks back to the guest room, abandoning his bowl. He sits on the edge of the nest, and Katsuki opens one eye before groaning and rolling onto his side. “Fuuuck.”
Shouta smells the arousal dripping off of him, and he snorts.
“Don’t fucking laugh at me,” Katsuki mumbles into the nest.
“Do you need help?”
“If you touch me, I’ll snap your fucking arm off.”
“You’re cramping?”
“Fucking duh.”
Shouta rests a hand on Katsuki’s shoulder, and he weakly slaps him. Shouta snorts, grabbing onto his arm so he can pull him into a sitting position. “C’mon, eat this.”
Katsuki growls. He grabs onto the side of the bowl as Shouta brings it to his mouth. It doesn’t really help much, but he lets him hold it while he tips it back. He watches closely, only tilting it further when he’s sure Katsuki swallowed.
After a few minutes of drinking, he pulls it back to give Katsuki a break. “I can feed my damn self.” Katsuki grumps.
“It’s good to see you’re lucid,” Shouta says in response. Katsuki rolls his eyes, and he’s drawn to the slight bags under them. “Do you remember much?”
Katsuki stares at Shouta’s shirt for a moment. “Fear.”
“I’m sorry.”
Katsuki shrugs and then winces, rubbing his stomach. “S’not your fault.” He pulls his sweaty shirt up, and Shouta almost activates his quirk as his hand glows slightly. Katsuki doesn’t seem to be letting off blasts, though.
“Works as a heating pad,” Katsuki explains when he sees him looking. “Helps with the pain.”
Shouta instinctively looks down, only to quickly look away when he sees the large wet patch around Katsuki’s crotch. He sure as hell smelt his slick, but seeing it is different. He clears his throat, ignoring how is most definitely letting out his own aroused scent.
“I can give you a bath when you’re finished if that’s something you’d want?” When Katsuki nods, he brings the bowl back up to his lips. Once it’s empty, Shouta hops out of the nest, taking it back to the sink and dumping his now cold soup. He grabs a shirt and a pair of sweatpants from his room before heading to the bathroom to start filling the tub.
After that’s taken care of, he goes back to the guest room and, much to Katsuki’s surprise, scoops him into a bridal carry.
“Wha- I can fucking walk!”
“You can.” Shouta acknowledges, grinning. Katsuki sneers at him.
When they reach the bathroom, he lets Katsuki stand on his own. He gets him stripped down and lets him sit in the tub before he starts taking care of him.
Katsuki groans, closing his eyes as Shouta scratches at his scalp, scrubbing the shampoo into his hair. It goes to show how tired he is when he doesn’t fight him. Even when Shouta carefully cleans the slick off his thighs.
He growls a little in warning, set off by the closeness, but Shouta quiets him with a few pets. When he’s all washed up, he dresses him in his clothes, rumbling at the cute sight of him absolutely drowning in his clothes.
Katsuki is blinking sleepily, so Shouta carries him back to his nest, making sure he drinks half a bottle of water before he lets him take a nap.
Katsuki grabs his arm before he leaves the nest, rubbing his nose against the scent gland on his wrist. He bites at it before nuzzling into it, letting out a soft purr. Shouta smiles, letting out a rumble of his own.
“Th’nks.” Katsuki mumbles.
“Anytime, pup.”
▪︎~~~~◇~~◇~~♡~~◇~~◇~~~~▪︎
The peace doesn’t last long. Katsuki wakes up halfway to feral and cramping up. He’s horny, very horny. Desperate, too, and Shouta can smell how it only makes him more scared.
The pain sets him off, and the horniness makes the pain worse. It’s a feedback loop of doom. One that Shouta wishes he could end. He isn’t sure how, though. Katsuki is set off if he touches anywhere close to his thighs. If he could get him to cum, then he’s sure Katsuki will feel calmer.
Shouta sighs, watching Katsuki guard his bowl. He’s practically inhaling the cum coated curry. His amusement only grows as Katsuki hisses at him. It’s like he has a sixth sense for when people think he’s acting cute.
“Pretty Omega.” He teases, laughing when Katsuki snaps his teeth at him.
When he’s done, he throws the bowl onto the floor. Shouta purses his lips, wincing at the sound of the metal clanking against the glass. “Now why did you have to do that?” He asks rhetorically.
Katsuki growls, pouncing on him. He doesn’t use his quirk, so Shouta lets him do as he pleases. He bites his shoulder, growling. “Never knew I would end up as a chew toy for a cute Omega.” Shouta muses to himself, chuckling when he gets a growl in return.
Katsuki licks where he bit before he moves, licking his clavicle. He ends up at Shouta’s scent gland, and he laps at the oils.
Shouta grabs Katsuki’s waist, simply holding him. He can feel his body relaxing, and within a few minutes he ends up boneless against him. He whines, his slick leaking right onto Shouta’s stomach. “Aw, did you get yourself scent drunk?” He asks affectionately, cupping Katsuki’s cheek. They’re warm and flushed. So so cute.
Katsuki whines, his hips twitching. Shouta’s hand slides down, pressing on his back, just above his ass. It makes it so Katsuki’s groin is flush against him.
Katsuki freezes, then growls, baring his teeth. Shouta pauses, and Katsuki’s hands start to spark. He attacks him again, and Shouta actually needs to activate his quirk this time to stop him from blowing them both up.
Katsuki looks exhausted and slightly out of it. Still, he fights. “That’s it.” Shouta decides then and there that this has gone on long enough. So, he scruffs him.
He keeps his hand on the back of Katsuki’s neck and holds him, taking every hit that he tries to throw at him. Eventually, his struggling ceases. Katsuki looks up at Shouta from where his head is lying on his chest. He looks dazed. “Alpha?” He asks, his voice quiet and vulnerable.
“Yes, Omega?”
“You… you won’t hurt me?”
“No, I would never hurt you.”
Shouta is hit with a wave of Katsuki’s aroused scent, and he chuckles. “Is my Omega feeling needy?”
Katsuki whimpers, clutching onto Shouta’s shirt for dear life. “M’ hot. N’ you’re…”
“I’m what?” Shouta smiles.
“Safe.”
The smile slides off his face, and he stares at Katsuki’s earnest expression. “You feel safe?”
Katsuki nods, and he lets out a relieved breath. “I’m so glad, Katsuki.”
“You protect.”
“I do.” Shouta pets Katsuki’s hair, delighted when he leans into the motion. “All I want to do is protect you.”
“Sensei… saved me…” Katsuki’s eyes slip shut. Shouta clenches his eyes shut, continuing to pet Katsuki. He made it over one hurdle. Katsuki feels safe, so he’s probably going to be able to keep him from going feral again. Unless he has more nightmares, that is.
If that doesn’t happen, then everything will hopefully go smoother. All he has to do is find out how to make Katsuki feel good so he doesn’t cramp up and hope he doesn’t make things worse during the process.
▪︎~~~~◇~~◇~~♡~~◇~~◇~~~~▪︎
Katsuki’s eyes flutter open. He takes a deep breath, and the scent of Shouta makes him whimper in need. He tries to move, but he's too exhausted to do anything more than move his head. “Shhh, pup.” Shouta coos, rumbling so deep Katsuki can feel it all the way in his core.
Shouta pets his hair, and Katsuki trills softly. “Are you all tired out?” His body is warm and pliant, draped over Shouta’s chest with his face stuffed in the man's neck. He’s surrounded by the scent of bourbon. It complements the warm, spicy cinnamon of his heat so well that he feels drunk off of it.
The fear from earlier is fading. He knows he’s safe now, soothed by the strong body under him. The rough voice and familiar rumbles. Shouta was always there when he needed him, and even now, he’s here making sure that man will not get to him.
Katsuki licks Shouta’s neck in a daze, savoring the rich oils on his tongue. Safe, safe, safe, safe repeats like a mantra in his head. Shouta stayed by his side even when he fought him. He provided for him like a proper alpha and didn’t try to take advantage of him. He’s not here to hurt him; he’s here to make sure he’s okay.
And fuck if that isn’t the hottest thing in the world to him right now.
Slick leaks from Katsuki’s pussy, and he lifts his head, looking into Shouta’s dark eyes. He blinks slowly, trying to weave through the haze in his mind. Unknown to him, he lets out another needy trill. Shouta’s hand pauses before he grips Katsuki’s chin so he can look into his eyes. “Do you feel better, Omega?”
“Mnh.” Katsuki tries to talk, but the words just won’t come out.
“Okay. C’mon.” Shouta sits up a little, and then there’s a fork full of food being brought to Katsuki’s mouth. When did that get here…?
Shouta holds a hand under his chin, his thumb stroking his jawbone soothingly. “It’s time to eat. We have to get some of your energy back.”
Katsuki opens his mouth, blinking at Shouta as the fork is carefully guided into his mouth so he can bite down. “There you go, just like that. Good boy.”
A bolt of arousal jolts down Katsuki’s spine, and he whines. Shouta is taking care of him. He has been from the start, even when Katsuki was biting and clawing at him. He was there, being the kindest, most patient Alpha. He can feel the man's hard cock against his stomach, but it’s like he doesn’t even know it's there, too focused on feeding Katsuki.
While Shouta’s head is tilted, looking down at the bowl next to them, Katsuki leans forward, nuzzling into his neck. He rubs Shouta’s scent all over himself, leaving playful bites wherever he can.
Shouta pets his hair, and he lets out a satisfied chirp. “You’re so sweet.” Shouta rumbles. “Such a perfect little Omega, aren’t you? Here, Baby.”
Katsuki turns his head to see Shouta holding out his hand, his palm cupped to keep a mysterious white liquid inside. Without thinking, Katsuki leans down to lap at it, moaning at the salty taste. “Mnh.” Katsuki purrs a little, his stomach warming as he licks it up.
“I’m sorry I can’t give you my cum the right way.” Shouta pets Katsuki's back with his free hand. “But we don’t want to scare you, do we? This will do for now.”
Katsuki’s body shudders against him, and an ache starts to bloom inside him. Deep, deep inside. He whines, and his breath hitches as alarms blare in his head. No, no, it’s not supposed to hurt. Why does it hurt? Is he- Hedoro-
“Shh, pup. There’s no need to be afraid.” Shouta soothes. His voice breaks through the haze of panic, allowing Katsuki to take a deep breath. Shouta’s scent fills the area around them, settling over him like a weighted blanket. That’s right, it’s just his Alpha. Hedoro can’t get to him here, not with Shouta here.
Still, it hurts!
Katsuki keens, butting his head against Shouta’s chin. He needs- he needs-
“Knot.” Katsuki’s voice is dry and cracks from disuse, but the word is unmistakable.
“You want my knot, Omega?” Shouta’s arousal spikes, and the smell makes Katsuki clench around nothing. Shouta moves the bowl outside of the nest. He wraps his arm around Katsuki’s back, his hand cupping the back of his neck.
Katsuki goes limp, staring up at him in a daze as he’s lowered into the nest.
“Are you sure you know what you’re even asking for?” Shouta asks warmly. He guides Katsuki’s hand to his hard cock. “Do you really think you’re ready for my knot? Or do you want the fake one first?”
He can take it! He can take anything! How dare Shouta assume he needs the help of a fake knot. He lets out a low warning growl.
“Alright. We will just have to see, then. I have it here in case. But first, I need to make sure you’re ready.” His hands trail down Katsuki’s body, and he instinctively hisses at the feel of hands on his thighs.
Shouta leans down, lowering his body onto the bed. He doesn’t try to crowd Katsuki. If anything, he tries to make himself smaller. He laps at the scent gland on Katsuki’s thigh, and he feels the slick drip out of him, most likely creating a puddle under him.
Shouta lets out calming rumbles, nuzzling into his thigh. Katsuki tries to move his arm to try to scratch at him, but his body won’t cooperate with him. He’s too tired, too horny to move. He growls weakly instead.
His Alpha croons. “I know, Baby, I know. It’s scary, isn’t it? I won’t hurt you, I promise.”
Katsuki keens, his brows furrowing as his pussy clenches around nothing. It hurts, and the pain only reminds him of before. But his Alpha said he wouldn’t hurt him. “P-promise?”
“Yes, Omega. I’ve got you. All I want to do is take the pain away. You’ve suffered long enough.” He slowly slides his hand closer to Katsuki’s pussy, and he growls so loud that it knocks the wind out of him.
“I’m going to touch you now,” Shouta warns. He moves his thumb, gently placing it on Katsuki’s clit. After a moment, he applies a slight pressure and starts circling it. “Ah.” Katsuki’s thighs shake, both from pleasure and fear.
“Feels good, right?” Katsuki nods. “That’s great. You’re doing so well, Katsuki. I’m just going to use my fingers now, okay?”
Katsuki nods again, looking down at Shouta. He smiles at him, his thumb continuously applying pressure to his clit while he runs two fingers through the slick leaking out of him. “You’re so wet. Aren’t you just perfect for me? Even if you’re scared, your pretty little pussy knows what you need.” His fingers slip through Katsuki’s folds, his middle finger prodding at his hole.
He waits there, gingerly pushing the tip of his finger in and out, watching Katsuki’s reactions. He’s shaking. He wants this, he needs it, he knows he does, but he’s also scared. What if Shouta realises just how much power he has in this situation and decides to take advantage of it? What if he hurts Katsuki, too? What if he hates it as much as he did with Izuku?
What if this is all his own fault and he’s a defective Omega?
“Relax.” Shouta’s voice lowers. He steadily dips his finger in further, parting Katsuki’s walls bit by bit until his knuckles meet Katsuki’s folds. “See, that doesn’t hurt, does it?”
Katsuki shakes his head. No, it doesn’t hurt. Not at all. Shouta curls his finger, and Katsuki’s leg jerks as he presses right against his g-spot. He tries to growl, and it comes out pathetically weak.
“You’re okay,” Shouta tells him. He doesn’t thrust his fingers. Rather, he moves his finger in that curling motion, over and over.
Katsuki’s spine arches, and he throws his head back. The pleasure is so intense he doesn’t know what to do with himself.
“You’re squeezing me so tight.” Shouta purrs, slipping another finger inside. The added pressure doesn’t hurt either, only heightens the sensations. “Am I gonna make you cum, pretty Baby?”
Katsuki gasps as he realizes that, yes, he is going to cum. He hasn’t allowed himself the pleasure of an orgasm since that night. It’s been so long that he hadn’t realized what was happening to his body. Katsuki’s hand buries itself in Shouta’s hair. He tugs at it, staring down at him with wide eyes.
He remembers how nice an orgasm feels. He’s had many before, and yet he’s terrified. It’s so good, but he doesn’t know if he can take it. He feels like he will fall apart.
“You can do it, Katsuki. I know you can take it.” He applies more pressure to Katsuki’s clit and adds a third finger. Katsuki grabs onto the side of his nest, letting out wounded whimpers. It feels so good, so, so good.
“You’ve got this. Come on, cum for me.” With Shouta’s skilled fingers pressing all of his spots, he can’t fight it. His cunt clenches around Shouta’s fingers, the warmth inside of him bursting. His thighs tremble, slick leaking out around Shouta’s fingers to create an even larger puddle.
He swears his nerves are on fire, and it feels so fucking good.
He doesn’t realize he’s keening, and when he finally hears it his body is heating up all over again. He sounds wrecked. Not because of pain, but pleasure. He’s feeling good.
“Knot.” He demands. His spine arches, and he stares at the ceiling with blurry eyes. “Want it now.”
“So demanding.” Shouta kisses his thigh, then his lower stomach, all the way up until he can place a sweet peck on Katsuki’s lips. He gasps, his hands burying themselves in Shouta’s hair to pull him in when he tries to move away.
He’s never kissed anyone before. He’s sure he’s not doing that good a job, either, but Shouta doesn’t seem to mind. He’s hungry as he licks into his mouth.
Katsuki hears the shuffling of clothes, and when he feels Shouta’s cock against his thigh, he freezes. A growl builds in his throat, his eyes watering in response to the instinctive fear. The feeling of a cock on him reminds him of Hedoro, of what happened when Izuku tried to help. The pain.
Shouta backs away just in time for Katsuki to miss biting his lip. He snaps at him, baring his teeth.
“I figured you wouldn’t like that.” Shouta doesn’t seem angry at his reaction. He smiles at him, wiping a tear off his cheek. Katsuki watches with bated breath as Shouta stuffs his cock back into his pants, only realizing how tense he is when his body relaxes now that there’s no cock in sight.
Shouta leans over the nest, grabbing the obnoxiously bright pink knotted dildo and a bottle of lube. He holds the dildo up, and Katsuki blinks at it. No alarms blare, thankfully. The color is enough to make it seem like it’s not a threat, which is why he picked it in the first place.
Shouta lowers the dildo. When it touches his thigh, he’s on edge again.
“Okay, not like that then,” Shouta mutters. He bites his lip. “I have an idea.” He grabs Katsuki’s shoulders, pulling him up so he’s sitting.
“You’re going to ride it, Katsuki. That way you control it. You set the pace and decide when to stop.” He sets the dildo down, holding the base while he guides Katsuki. He growls again when he feels the fake tip touch his folds.
His nails dig into Shouta’s shoulders. He’s slowly lowered onto the dildo, growling and snapping his teeth with every inch he takes. He tries to set off his quirk, but he’s too exhausted to do anything but sink onto the fake cock.
When his folds press against the fake knot, Shouta stops. Katsuki is still fighting and squirming. Shouta slowly lets him go, his hands only hovering over Katsuki’s trembling body.
Katsuki’s growls slowly taper off. He sits there, panting, his pussy squeezing down. It feels good. His hips twitch. He tries to lift himself, but he’s too tired. He whines in distress. He needs more, but he can’t do it himself.
Shouta can’t touch him without him panicking, though. Tears well in his eyes.
“It’s okay.” Shouta coos, grabbing a few strands of his capture weapon and draping them over his wrist. He grabs onto it, bringing it up to his nose so he can huff the scent. He pants into it, grinding his hips down.
“That’s it. I know you like my scent.” Shouta pulls out more strands, wrapping them loosely around his hips and thighs. He places his hands over the strands on his hips. It’s faint, but Katsuki can still feel his hands. He’s too tired to fight it. “Noooo.” Katsuki whines, his head falling back.
“I know, Omega. I know.” His scent sours from both the need and distress. It’s all too much.
Shouta uses his grip and moves Katsuki’s hips, rocking him against the dildo. He moans softly, biting on the capture weapon and growling into it.
Shouta's hands tighten on his hips, and he slowly lifts Katsuki in time with his helpless attempts at bouncing. “Ngh, yes!” He shouts when the head knocks against his g-spot.
Shouta smiles. “There you go. Feeling good, Katsuki?”
Katsuki nods rapidly, biting down harder. His breath is choppy, little whines forced out of him with every thrust. He’s sensitive, and within a few minutes, he feels an orgasm welling. His whines are mixed with short growls as he gets closer, both wanting to cum and once again scared.
This time it’s for a whole different reason. Cumming around a cock feels wrong now. He knows it’s not, and he never came at all the previous times he’s had one inside, but still. It’s part of the reason for all of this pain.
“Are you going to cum? You’re so good, Omega.” Shouta’s voice is rough, and his eyes snap open to see how flushed he is. He’s obviously affected by the sight in front of him. “ So strong. I’m so proud of you.”
Katsuki chirps around the capture weapon in his mouth, and Shouta chuffs. “So perfect. Use this cock to make yourself cum.”
Well, when Shouta puts it that way, it doesn’t seem so scary. He’s right, too. Katsuki is in charge right now. Shouta is here protecting him and helping him. He’s following Katsuki’s movements, only lifting him up because he knows that’s what Katsuki wants.
Katsuki’s cunt squeezes around the toy, and he cums. He moans loudly, his voice muffled by the capture weapon. His hips grind down, and Shouta helps. He doesn’t mean to, but he’s so wet that the knot slips inside.
Katsuki’s body locks up, trembling as his orgasm is heightened. “Holy fuuuck.” He wails. Shouta holds him through it, whispering praises to him until he collapses against him. He holds him against his chest and lies back, slipping his own thigh between Katsuki’s to keep the knot inside.
Katsuki nuzzles into his chest. Shouta chuckles, grabbing onto the capture weapon still in his mouth. “Are you going to let this go, pup?”
Katsuki growls, pulling it out of his mouth. His nose wrinkles, not liking the feeling of his dry as hell tongue.
“Good boy.” He says. Katsuki’s chest warms. He trills, purring when Shouta chuffs in response.
Shouta rubs his wrist on Katsuki’s neck, their scents melding together. He relaxes into him, his eyes slipping closed as he purrs, safe and content in his Alpha’s arms.
