Chapter Text
Kurogiri had gotten irritable in Tartarus. He hated it here, so much. But he’d been getting even more irritable than he usually was as of the last few days. The heroes at Tartarus had also noticed, trying to suppress Kurogiri’s outbursts. It never worked of course. Kurogiri hated everything about this place of course he was going to be upset. It wasn’t until he started feeling hot on top of irritability that he realized what was happening. Unfortunately, so did the heroes at Tartarus. Kurogiri was beginning to fall into a heat.
A muzzle was forced onto him once again. He had been tranquilized and even then he was growling and spitting at the people forcing him into this. Next was the collar and cuffs. The collar was nowhere near as comfortable as the one AFO made custom to him and he could already feel it rubbing his neck raw. Kurogiri tried biting and getting them away as they chained him up to keep him from lunging at them.
Kurogiri could only yowl in anger, attempting to take the muzzle off with brute force. He banged the sides of it against the floor and chains. He growled and clawed at it, unable to get it off. They’d also injected him with quirk suppressing drugs. He was absolutely useless. Kurogiri was showing his teeth and snarling at anyone who came in.
That included the familiar face of Shouta Aizawa. Why did they bring him in? Kurogiri made sure to let this man know he wasn’t going to submit. He needed all of them to know he’d continue fighting. Anxiety spiked in his chest as the scent of the alpha- Shouta- began to surround him. The alpha was trying to calm him down but it only did the opposite. He was somewhere wrong. It was sterile and scentless. His pack wasn’t there, his pup wasn’t there. His instincts made him terrified.
“Oboro, it’s okay. Fuck- you shouldn’t be like this.” Shouta said softly, growling a bit to himself seeing the muzzle sat on Kurogiri’s face.
“My name is Kurogiri.” Kurogiri spat and growled at him. All his body language would tell anyone sane not to take off the muzzle. He snarled loudly to let him know he will bite. His ears were pinned back to his head.
Shouta didn’t seem to care though, he reached his hands out to Kurogiri. Kurogiri went stiff and waited as he felt the clasps of the muzzle become loose and unfasten. Almost instantly, Kurogiri was throwing Shouta down and biting him hard enough to take a piece of flesh off his shoulder. There was a whimper and gasp from the other man, but instead of being afraid a shaky hand came up to Kurogiri’s head and he started petting his hair. A purr rumbled from Shouta’s throat, trying to comfort him despite his own ears being back now. “It’s okay… You’re safe with me now…”
Kurogiri slowly let go with his fangs. His head hurt and spun. He remembered someone else in the past carefully taking those muzzles off. Hands so small and gentle. But now those same hands were rough with time. The same boy he’d wanted to mate. They’d promised their whole futures with each other…
God his heat was making him not think straight. It was all the heat. Kurogiri lifted his head enough to look at Shouta, who just gave him another purr as his ears slowly came back forward. “I won’t let them hurt you Oboro.”
Oboro… stop calling me Oboro. Kurogiri had wanted to say that so badly. That name only brought him back pain. Kurogiri’s ears stayed pinned back.
Shouta continued to pet Kurogiri’s head attempting to give him comfort through touch and scent. There was familiarity to it, but Shouta could never understand him now. Kurogiri growled at him. “Stop it.”
Shouta froze and slowly moved his hands away. “What’s wrong?”
“I’m not Oboro. You don’t know what I’ve been through, and I don’t expect you to understand where I stand now.” Kurogiri snapped at him.
Shouta furrowed his eyebrows at him. “Then tell me. How am I supposed to understand you if you won’t let me know?”
Kurogiri shoved him away, still growling. “I’m an omega now Shouta, think about for a second why someone would do that.”
“I assumed AFO just wanted to feel like the one in charge right? He had to control you somehow.” Shouta answered.
“He needed pups Shouta.” Kurogiri felt his chest tighten. His emotions were out of whack with how close he was to heat. “He made me into an omega, forced me to have pups I couldn’t even give birth to without intervention, then ripped them away from me on my birthday. And fucking hell he still treated me far better than these heroes have!”
Shouta stared at Kurogiri in shock. “I’m sorry…” He said almost distantly, studying Kurogiri’s body now. “I didn’t know. I don’t like what they’re doing to you. But I sure as hell don’t want you going back there either.”
“They’re my family!” Kurogiri almost sobbed, gritting his teeth to hold back. “I have nothing else left. I had a mate and a pack, I was finally healing and now I’ve been fucking torn away from that again. My heart can’t handle being taken away from everything that makes me happy all the time. I won’t get attached to you again because if I do we will be on opposite sides when the LOV inevitably launches an attack on you heroes. And I don’t think I could handle that.”
Shouta could smell the sour scent of the omega, and he tried closing the space between them again. “Come home with me Oboro.”
Kurogiri felt Shouta’s hands on his shoulder and cheek. “I can’t.”
“Why not?” Shouta asked anxiously.
“Let me rephrase… I won’t.” Kurogiri insisted.
Shouta huffed. “Why won’t you come back with us?”
“Because… I can’t fight my baby.” He looked at Shouta. “My baby will always be my absolute priority, Shouta. So will my new family that has been there for me.”
Shouta seemed to take a moment to process what Kurogiri said, and then he sighed while putting his ears back. “No one should expect an omega to fight their pup, no matter who it is.”
Kurogiri finally relaxed into Shouta’s touch. Or… What did he want to be called? Oboro? No… not exactly that either. “My name… I don’t expect you to call me Kurogiri. Kurogiri is who I am now, I need you to understand that much…”
Shouta just stared at the ground, nodding slightly. “Right.”
“I’m not the Oboro you knew.” Kurogiri continued. “And a lot of my memories have been extremely suppressed. I don’t remember everything. When things come up it hurts, it’s a lot to process.”
Shouta slowly lifted his gaze from the ground. “What do you remember?”
“I remember eating on the roof… you always taking off my muzzle and collar… Wanting to spend my life with you… Some other small things here and there.” Kurogiri admitted. “And I remember how much I loved you and the other two.”
At that his body decided it wasn’t time to talk anymore. Kurogiri felt the sharp pain of heat in his stomach and he groaned. He tried rubbing his stomach to ease the pain but the scent of someone he considered mate was in the room and it made the pain more intense. Shouta’s hands were on him also trying to ease that pain. He’d hardly even realized he was whimpering and crying.
“No… no pups…” Kurogiri cried quietly.
“I won’t do that, don’t worry.” Shouta purred at him softly, pulling him close.
Kurogiri nervously allowed Shouta to touch him. His inner omega was begging for the alpha in front of him but Kurogiri couldn’t let it control him. He was terrified of going into heat in front of this hero. It was inevitable at this point it’s not like he could stop it.
“I’m not going to do anything until you give me permission.” Shouta promised. The scent he was giving Kurogiri told him he was being honest. It helped him relax at least a bit.
“Please promise… you’ll stop if I spiral.” Kurogiri urged with a whimper.
“I promise.” Shouta promised, putting a hand on the back of his head. “Can I kiss you?”
Kurogiri nodded, closing his eyes. “Make me relax.”
Rough lips pressed against his own, though he was sure his own weren't any better. He breathed into it. A purr came out of Shouta’s throat as they kissed and Kurogiri offered to allow him to deepen it. A hand splayed across Kurogiri’s back and he whined through the kiss.
Anxiety ebbed at his stomach but something on the inside was pushing it away. The scent wasn’t Atsuhiro’s but it was still a scent he distinctly remembered fondly. As much as it hurt, Kurogiri felt for his instincts he had to let himself remember this time.
—---------------------------------------------------
Oboro and Shouta had gone out to one of Nemuri’s beach houses. The Kayama family was rich rich, and it always fascinated Oboro the type of stuff humans would spend money on. Oboro didn’t grow up with much money at all, his dad worked so much he had to raise his little brother most of the time. He also had learned how to cook out of necessity. But here was Nemuri’s parents, spending money on a house next to the beach. They had two others.
“Man if I had money I’d be spending it to get a more comfortable collar or better hybrid food.” Oboro joked.
Shouta was trying to help Nemuri move her bags into the house. They all went to a getaway after they’d been released for a two week break including their internship. His Purple Highness insisted on them having a good rest. Shouta looked at Oboro. “That wouldn’t even come close in price to this house.”
“Okay but if I had that kind of money I’d be spending it more practically duh.” Oboro chuckled, watching Shouta get nearly crushed by bags. He laughed more and took them off.
Shouta just huffed at Oboro. “God why does this woman need so many bags? Also Oboro, if you had that much money you wouldn’t have to wear a collar and muzzle.”
Oboro sort of pondered for a second then started dragging the bags in. “Then that’s more motivation to become number one!”
“In your dreams.” Shouta sounded slightly amused.
They had gotten all the bags in after about thirty minutes. Now granted, the beach house wasn’t super big. Shouta and Oboro had to share a room, not that Oboro had any complaints about this. He thought maybe they’d have time to get a little hot and heated.
Except he didn’t get to that night. Or the next. Nemuri had jam packed their days with so many activities that Oboro and Shouta were both too exhausted to even try. Oboro was only six months into his alpha presentation at this point, so he was constantly horny. He just wanted to have sex with his boyfriend, was that too much to ask?
They finally had a chill day after the first two though, and Oboro definitely wanted to take advantage of it. He even brought condoms just in case! There were no parents around to interrupt either. Oboro was not about to be stopped from going through with his plan. Obviously unless of course Shouta didn’t want to.
They were still awake late at night, though Nemuri and Hizashi had both gone to their rooms. Oboro and Shouta were still definitely awake though. Awake and awkward. Oboro had no idea how he was going to initiate this. He could feel tension in Shouta too despite Oboro cuddling up to him and giving him a gentle massage in the shoulders and hips. Shouta laid stiffly against Oboro.
“Sooo.” Oboro finally broke the silence. “Whatcha thinking?” God dammit, that was not smooth Oboro.
Shouta glanced up at him. “Uh… nothing really.”
Oboro leaned down to kiss him. “Do you wanna…?”
Shouta shifted his hips away from Oboro slightly. “Wanna what?” He said, trying and failing to hide his blush.
“You know.” Oboro tried figuring out what to say without being too blunt. “Doing it?” It’s not like they hadn’t slept together before but man Oboro was always super awkward asking for sex.
Shouta snorted, the closest thing he had to laughing. “You’re asking if I wanna have sex with you.”
“Yessss.” Oboro whined. Shouta moved to face him and kneed Oboro’s stomach on accident which made him yelp.
Yeah they were not off to a good start here. But Oboro could only laugh, and that devolved into heated kisses. Heated kisses turned into Oboro pinning down Shouta by the hips. And then he worked Shouta open and sank in, swallowing his whimpers and whines…
—-----------------------------------------------
Kurogiri was brought away from his memories with a loud whine. Not from Shouta, from himself. Somewhere when Kurogiri had gotten lost in his head, Shouta had removed both of their clothes and started prepping him. Shouta… my mate Shouta… Kurogiri’s inner omega whined. He recognized the man now. He needed to.
They were flipped from how they used to be. Oboro used to take charge. But Kurogiri isn’t Oboro anymore. Or at least… not in the way he used to be. Maybe he still had some qualities. Shouta had gone from a thin little kid to very well toned and he had incredibly strong arms. He had new scars from protecting his students, some of them Tomura and Kurogiri themselves had given him.
We are not that different… we only protect different things. Kurogiri realized at this moment, trying to look at Shouta’s face. Shouta had a soft expression. “You seemed to space out but you were still begging. You back now?”
Kurogiri just slowly nodded. Suddenly he threw his head back and moaned loudly at the ministrations Shouta did. He got that spot inside that made Kurogiri see stars. “Good, because I wanted you to be here when I made you feel good.”
Kurogiri couldn’t help but whine again, his senses being clouded by his heat. It was beginning to be in full swing. “Alpha more~”
Shouta leaned down to him to kiss him, and Kurogiri gratefully kissed back. The kiss was deep and he kept fingering him as they kissed. Shouta licked inside of Kurogiri’s mouth, getting his soft palette making Kurogiri whimper. His legs spread more giving him full view.
“Fuck Ob- Kuro.” Shouta breathed out, petting Kurogiri’s thigh with his free hand.
“Alpha I need your cock.” Kurogiri couldn’t help but whimper, feeling slick gush out of his hole around Shouta’s fingers. This made Shouta gasp and nip at Kurogiri’s thighs, leaving marks.
“You’ll get your alpha’s cock don’t worry baby.” Shouta groaned, pulling his fingers out. “They didn’t supply me with-”
“I don’t care I have an implant. If another alpha brings that up I swear to god. Just fucking plow me into next week Shouta or so help me.” Kurogiri growled.
Shouta didn’t need to be told twice. He moved to get his cock lubed up and Kurogiri got to get a look and lord. He was much thicker than Atsuhiro, and Kurogiri needed that knot. He felt more slick come out as he whined.
“Be patient, I’m not trying to hurt you.” Shouta purred, now moving to gently grab Kurogiri’s wrists and push himself in.
Kurogiri cried in pleasure at the stretch. He spread his legs as much as he could. “Please alpha oh god please~”
Shouta hushed Kurogiri with kisses, still slowly pushing himself in. He was clearly allowing Kurogiri to adjust. Kurogiri however wanted him to fuck him so hard he couldn’t walk the next day. He began to whine again and it was silenced with another kiss from Shouta. “Don’t push it.” Shouta groaned into Kurogiri’s mouth as he bottomed out.
Kurogiri kept whining, his ears back. He needed more stimulation. He didn’t have enough, he needed more. “Please alpha move.”
Shouta gently rubbed his thumbs over Kurogiri’s hips, trying to keep himself under control. Kurogiri could see the way Shouta looked that his inner alpha really wanted to take over. Kurogiri shifted his hips to get Shouta even deeper and he gasped. He felt more slick gush out with a shiver.
That scene made the alpha take over and pull out before slamming back in. Kurogiri screamed in pleasure, arching his back into it. “Oh fuck alpha yes~”
A deep growl came from Shouta as he started thrusting into Kurogiri rough and deep. Kurogiri pinned his ears back and moaned. The alpha’s cock hit him so deep and filled him up just right. Hands stroked his sides and lips nibbled up his throat. Kurogiri’s fangs hurt, he needed to bite.
Shouta kept thrusting into Kurogiri hard making him moan and whimper. Every thrust made Kurogiri let out another loud moan. He wrapped his legs and arms around him, trying to pull him impossibly closer. Shouta was growling at his neck now. “Alpha please~” Kurogiri whimpered.
Kurogiri grazed his own fangs over Shouta’s shoulder which made the alpha thrust rougher and growl louder. “Fuck alpha!~”
The familiar heat of needing to cum was quickly arising in his stomach and he allowed his head to fall back with his mouth open. Whimpers and moans continued to fall out of Kurogiri’s mouth. Shouta’s cock was so deep he was sure if he looked down he’d see it through his stomach.
“Alpha I-” Kurogiri started to tell him he was going to cum, but wasn’t able to finish as Shouta did a particularly bruising thrust that made the omega cum on the spot. Kurogiri was shaking as he came, not trying to keep himself quiet. He tightened around Shouta. “Knot please knot~” Kurogiri begged.
Shouta didn’t let up on his brutal pace and fucked Kurogiri hard through his orgasm. At this point the alpha was chasing his own. Kurogiri could feel the knot forming and catching on his rim. This made him gasp and whimper, his teeth hovering back over Shouta’s shoulder.
Shouta growled loudly and started fucking his knot into Kurogiri, gripping Kurogiri tightly. The stretch was painful, but at this moment it only caused Kurogiri to cum again. His own cock released cum onto his stomach, painting it white. He moaned out nearly screaming, and then bit down on Shouta’s shoulder taking any blood he could.
Finally he felt the knot fully take place and the alpha started cumming with a loud moan himself. Kurogiri could feel the alpha’s cock pulse and the warm cum deep inside. Kurogiri was panting, trying to keep hold of Shouta. He took a minute or two to fully empty into Kurogiri, keeping him locked with a huge knot. Kurogiri glanced down at his stomach which was now bulging as if he was pregnant.
Unfortunately this didn’t settle well with his inner omega. It was almost immediately apparent to Shouta who instantly came back, pushing his own alpha to the back. “Woah Oboro hey you’re okay.” He immediately started trying to hush him again.
All Kurogiri could think about was his babies. He felt his eyes burn. “Don’t take them… please don’t take my pups.” He whined pathetically, the last part coming out in a near sob.
Shouta was scenting Kurogiri heavily, trying to calm him. “No one will take your pups… Your pups are safe.”
Kurogiri continued to sob, less of his inner omega influencing him now. He could only think of the unfairness of it all. His babies that he had hated so much that he’d learned to love only to have them taken on his 18th birthday. He hated his birthday. The unfairness of the last time ever holding his daughter being when she was only a month old. That he raised Tenko without the boy ever knowing that Kurogiri is actually his birth parent.
“It would have been better if I hated them.” Kurogiri sobbed out loud.
Shouta was still trying to comfort but there was the scent of confusion. “What do you mean?”
“AFO forced me to have them. He forced me to have babies that I hated. They were parasites, they ruined my body. But it wasn’t their fault. They’re innocent babies. And I fucking loved them. With every fiber of my being I loved my pups and they were ripped away from me.” Kurogiri managed to say through sobs, hiccuping as he tried breathing. “AFO ruined them, my son doesn’t even know I’m his dam and my daughter is dead. I didn’t even get to hold her dead body. This would’ve been so much easier if I just hated them.”
Shouta listened, holding Kurogiri close. He wiped his tears and let him hide into his chest. “I’m… I’m so sorry Oboro…”
Kurogiri was still hiccuping but the sobs were beginning to die down. He kept taking Shouta’s comforting scent. God it brought back memories, good ones this time. It was bittersweet for him to think about. The more he allowed it the more memories came…
He wasn’t Oboro anymore, but he wasn’t just Kurogiri either. He’s no hero, he couldn’t in any good conscience be one after what he’s seen. But he’s not entirely a villain either. He didn’t think so anyway. Villains were evil and selfish. He wanted to fight for what was right with his family. He needed to protect them. But society said that makes him a villain…
All he could hope was that his friends might understand.
