Work Text:
“Alright, class, I have your test papers here, all graded. However, this has not yet been uploaded to our class dashboard because we will be double-checking your papers. If you feel you answered one of the questions correctly, you may approach my desk to explain why you think your answer should be accepted. Any questions?” Izuku asked, patting the stack of papers on his desk, “Okay then, Mr.Aoyama,” He called on, plucking the student’s paper off the pile and holding out his arm.
“This is not in alphabetical order!” He called out in a loud voice, “Mr.Bakugou!” The blonde walked to the front, snatching the paper and staring at the red marks, “HA?!”
Izuku stopped handing out the papers, popping his hip, “My exact reaction, Mr.Bakugou, I must say, I’m quite disappointed.” Pursing his lip, Izuku watched as Bakugou snapped his head towards Izuku, “You shitty professor, you might’ve fucking graded this wrong!” The beta protested, Izuku raised an eyebrow at him, “Then sit down and we will double check it as I have instructed, Bakugou.” He growled, flashing his fangs at the protesting blonde.
The class went quiet. Professor Izuku has always been polite and calm with his students and has been easily approachable, except when talking to Katsuki. Everyone in this class knows how much the beta aggravated Professor Izuku, but not once did Izuku ever bare his fangs at Katsuki.
Feeling himself shiver, Katsuki stomped his way back to his seat, opening his iPad and scrolling through his notes. Katsuki knows something might’ve gone wrong. Biology might not be his strong suit, but he worked hard to study for this exam! He aggressively scrolled through his Embryology notes, trying to match his answers to them.
“Mr.Kirishima,” Izuku continued, calling on students, “Hell yeah!” Kirishima pumped his fist up into the air, “Mr. Kirishima, you barely passed…” Izuku raised an eyebrow at the redhead. “What’s that last word you said, teach?”
“Passed?”
“Exactly!” Kirishima cheered, a pep in his step as he walked back to his seat next to Katsuki’s. Izuku just shook his head, his whole demeanor changing at the student’s antics.
“Ms.Ochako”
“Ms.Momo”
“Mr.Todoroki”
“Mr. Kaminari”
“Something’s wrong, Kiri…There’s no fucking way I failed this fucking bad.” Katsuki grumbled while Kirishima just sat on his chair, legs up on the table. “S’not that bad, Bakubro. You still passed.” Kirishima replied, scrolling on his phone.
“I got a 63, Shitty Hair! I-I don’t fucking get it, FUCK!” Katsuki cussed, banging his head on the desk.
“Language, Bakugou.” He heard the professor scolding him, “I swear he fucking hates my guts, Kiri.” Bakugou sighs, “Well, you’re always insulting him, disrespecting him, being rude, should I go on?” Kirishima questioned. Katsuki just banged his head once more.
“For the first multiple-choice question, in cardiogenesis, following the fusion of the heart vesicles, the first structure of the heart that is formed: A, ventricle, B, auricle, C, conotruncus, and D, bulbus cordis, what is the answer?” Izuku asked, flashing the question on the board.
“Yes, Ms.Uraraka?” “C, the conotruncus.” She answered, “Good job.” Izuku praised, smiling at the omega. Ochako blushed, and Katsuki scoffed while rolling his eyes at the woman.
Everyone was aware of how much Ochako wanted Professor Izuku. The “oh-so-perfect” omega for him would be someone like her, and contrary to popular belief, Katsuki does not think so. The alpha would be too good for someone like her. But still, he has no say in some extra’s opinion on Professor Izuku, he’s just a goddamn beta for fuck’s sake.
“For the fifth question, what part of the 72-hour cross-section of a chick embryo?” Izuku asked, flashing an image on the screen, “No one?” He questioned, seeing that no one was raising their hand. Ochako raised her hand again, making the alpha sigh. “Anyone besides Ms.Uraraka?” He questioned the class again, raising a brow.
The omega slumped onto her seat, feeling rejected. Katsuki just scoffed again, “Alright, Mr.Bakugou, it seems like you want to say something, answer the question.” Izuku called on, taunting the blonde.
“That’s the fucking Metencephalon.”
“Wrong.” Izuku smugly smirked, “This is the Telencephalon, does anyone would like to explain why this is not the Metencephalon?” The professor continued, making Katsuki blush, feeling embarrassed by his mistake.
“Yes, Mr.Mashirao?”
“It’s the Telencephalon because it’s located at the downward bending at the front side of the brain.” Ojiro answered, “Good job, Mr.Mashirao!” Izuku praised, flashing a bright smile at the student.
Katsuki slumped further into his seat, convinced that the alpha actually just hates his guts and would rather fail him than help him pass.
“Now, for the 72-hour cross-section chick embryo again, give me three developmental advancements for this stage, Mr. Kirishima.” Kirishima brought his foot down from the table, standing up, “Okay, so, first is the flexion and torsion, second is the brain differentiation, and then the development of hearing?” Kirishima answered, unsure.
“Are you answering me or questioning me, Mr.Kirishima?” Izuku asked, chuckling at the man. Kirishima just scratched the back of his neck, “Answering?”
Izuku let out a throaty laugh, “Good job, Mr. Kirishima.”
“Sir! Can I mark this as correct?” Someone questioned, not caring anymore. Katsuki just looked down at his fiddling hands, refusing to look at his paper in case it had answers that could be corrected.
“How about this, true or false, during the fetal life stage of development, the kidneys are responsible for waste excretion?” Izuku’s eyes scanned the room, seeing students looking down at their papers, trying not to meet his eyes.
“Mr.Bakugou, what’s the answer, true or false?” He questioned, eyes darkening as he watched Katsuki defeatedly sigh, “True?”
Izuku shook his head in disappointment, “No, it’s false. Did you even study for the test, Mr.Bakugou? I’m quite disappointed with your performance.”
Tears sprang to Katsuki’s eyes, feeling dejected. He knew he had studied so hard for this test. He tried his best, he really did, but he had no idea why he was failing this class so badly. He aced the previous tests, so why is he suddenly doing so bad for his final exams? Katsuki took a deep breath, leaning back on his chair and looking up at the ceiling to stop the tears from dripping.
Kirishima looked at his best friend, worried, but all that he could do was pat the beta’s shoulder, shooting him a smile when Katsuki looked at him, “It’s alright, Kats.”
The rest of the class went by the same route: Izuku preying on Katsuki, Katsuki already too bothered to answer correctly, and Izuku showing and verbalizing how disappointed he was with the beta.
—
“May I talk to you after class, Mr.Bakugou?” Izuku asked as the bell rang, signaling the end of their session. Katsuki looked at Kirishima, who just smiled softly at him, patting his shoulder, nudging him to go.
Nodding, Katsuki walked up front, standing beside Izuku’s table with his head down, crossing and uncrossing his foot.
The professor watched as the students left the classroom, some shooting the beta pitiful glances, “What happened, Katsuki?” Izuku questioned, now sitting behind the desk.
“I don’t fucking know, okay?” Katsuki replied, throat closing up at the threat of his tears spilling.
“You used to do so well in my class despite the acting out, so what gives, Katsuki?” Izuku pushed on, taunting Katsuki again with that god-awful alpha command.
“GOSH! I HAVE NO IDEA, IZUKU! I’M TRYING SO HARD, AND HERE YOU ARE MAKING ME FEEL LIKE ABSOLUTE SHIT IN FRONT OF ALL THESE FUCKING EXTRAS! YOU, GOD, YOU MAKE ME FEEL SO STUPID! I’M TRYING SO HARD TO BE SO GOOD!” Katsuki shouted, tears spilling that he desperately tried to wipe with the back of his hand.
Izuku sat there, in shock at Katsuki’s outburst. “Kacchan…” Izuku shushed, standing up, pulling the blonde into a hug. Katsuki sobbed into the alpha’s chest, the difference in their heights evident as he tried to push the alpha away.
Although everyone was aware that Katsuki despised Izuku, no one knew why.
“Fuck you, Izuku, let go of me, you, Shitty Nerd,” Katsuki said through hiccups, punching the alpha’s chest, unsuccessfully freeing himself.
“That’s enough, Kacchan.” Izuku commanded, again, “Fuck you and your commanding, shit won’t fucking work on me, you know that, right? You fucking bird-brain!” Katsuki snarled, kicking Izuku as he tried to free himself from the alpha.
Sighing, Izuku lifted Katsuki up from under his arms, forcing the blonde to wrap his arms around Izuku’s neck and legs around his waist, walking back to his chair and sitting Katsuki on his desk.
“I’m sorry, baby. Look at me,” Izuku said softly, grasping Katsuki’s chin, making him look up.
The beta was still crying, tears streaming down his beautiful porcelain skin, nose red, his long lashes wet with tears that shone like diamonds. Izuku smiled softly at the blonde, wiping his tears away with his thumb.
“I’m so sorry, sweetheart. I know you resent me, I get it, and we’ve postponed our need to talk about things for quite a while. Do you want to talk about it now that the term is about to end?” He asked gently, still wiping Katsuki’s tears.
Katsuki didn’t trust his voice anymore and shook his head no.
“Why not, hmm?” Izuku questioned further, holding the blonde by the hips and rubbing it soothingly. “You acted like you barely knew me for months, Izuku. You made me feel like shit all the time for this class. I tried so hard to do good, and when I did, you barely said anything. And-and then…” A sob broke through Katsuki again, shaking his frame.
Izuku shushed the sobbing man on his desk, bending down to place kisses on his thigh and laying his head on the blonde's lap. “And then?” he pushed.
“T-then you only talk to me because you’re disappointed in m-me. Fucking patronizing me and shit, making me look like a fucking idiot over and over again. I don’t wanna talk anymore, Izuku.” Katsuki elaborated, voice wavering from crying. Pushing Izuku away from his lap, he tried to get off the desk.
“I get that you’re mad, Katsuki. I’m sorry. However, you do know I can’t have a relationship with my students, right?” Whispering, Izuku continues to wipe Katsuki’s tears even though he refused to look at him.
“Seems like you do,” Katsuki said under his breath, “What was that, sweetheart?” Izuku asked, not understanding what Katsuki said.
“I said it seems like you do.” He shot back, looking at Izuku menacingly.
“What do you mean, Kacchan?” Izuku tilted his head in confusion, “You know what I mean, Izuku.” Katsuki spat, roughly wiping his tears away and slapping Izuku’s hand away from him.
“No, Katsuki, I do not. Stop being so difficult.” Annoyed, Izuku grabbed Katsuki’s hands, pinning them on the desk. This set off Katsuki in an even worse mood, “The fuck do you mean you don’t? Fuck you, Izuku! Fucking Ochako has been giving you gifts for months! You keep on accepting them! An alpha! Accepting an omega’s gift, and you don't know? Oh fuck you, Izuku. Fuck you and your bullshit!” Katsuki shouted; he was now kicking and pushing Izuku away with more fervor, successfully freeing himself.
“Katsuki I-” Izuku tried to reason, reaching for Katsuki again as the blonde created some distance between them.
“No, Izuku. You don’t get to leave me in the dust for seven fucking years, then show up as my Embryology professor. You don’t get to act like you don’t know me, embarrass me in front of all these people, and then bare your fucking teeth at me when you’re disappointed at me. You don’t get to act all oblivious when you’re well fucking aware that an omega has been flirting with you. You don’t get to call me sweetheart fucking baby after all these years. Fuck you, Izuku. Fail me for all I care. I’ve had enough of your shit.” Katsuki spat. Walking out of the room and slammed the door behind him.
Izuku stood there, dumbfounded, rubbing his jaw from how hard he had been clenching it since Katsuki started. Sighing, Izuku sat back in his chair, putting his head in his hands as he thought about ways to talk to Katsuki.
—
It's been two weeks since Izuku and Katsuki fought, the trimester already ended, and Katsuki was now back home in Musutafu.
“KATSUKI!” Mitsuki shouted from the bottom of the stairs, “WHAT?” He shouted back, placing the comic he was reading down beside him on his bed, “COME DOWN AND BRING THIS TO INKO!” His mom shouted.
Groaning, Katsuki stood up from his bed, putting on a random hoodie he had picked up from his desk chair as he headed downstairs.
“What’s this, hag?” Katsuki questioned as Mitsuki handed him a Tupperware of food. “I made too much Katsudon, and I had bought some extra cream puffs earlier to give to her.” She replied, pushing Katsuki to the gengkan.
Katsuki sighed, slipping his clogs on as he was about to reach for the door. Mitsuki grabbed his forearm, turning him to face her.
“You ok, Brat?” She asked softly. Even if Mitsuki was a bit tough on Katsuki, she knows her child, and her child, right now, looks depressed as shit. He had bags under his eyes, his skin was dull, and he had this look in his eyes that just screamed ‘I’m going through shit’.
Katsuki stared into Mitsuki’s eyes, tears starting to form at his mother’s gentleness, “I’m okay, Ma. It’s nothing.” He replied, smiling softly. Mitsuki nodded, pulling in her son to kiss the top of his head.
“Alright, Brat. We’ll eat lunch after you give that to Inko, K?”
“Okay.” He replied, opening the door and closing it softly behind him.
Katsuki and his mom clash all the time, since they're almost the same, but he knows his mom means well. Tough love, they call it.
He holds the Tupperwares filled with food gingerly as he walks on the sidewalk. Mrs. Midoriya lives only a few houses away from the Katsuki household, which is why Izuku and Katsuki met when Katsuki was in middle school, looking for a tutor to pass UA, and Izuku was in med school, looking for a side job to help his mom. Katsuki’s family is well off; having a designer dad and a model mom was the reason. So you could say Izuku was well paid while tutoring Katsuki.
As he reached the door of the Midoriya, he raised his hand to knock. The cool air penetrated the hoodie he was wearing slightly, making him shiver a bit. As he waited for the door to open, Katsuki fiddled with the bag holding the Tupperware filled with food, “Hi, Mrs.Midoriya, Mom wante-” Katsuki stopped his greeting when he looked up, and instead of seeing the small omega with green hair, he came face to face with a chest he was oh so familiar with.
A scowl took over his face as he shoved the food into Izuku’s hand, “Bye.” Turning around, Katsuki started walking briskly.
“Kacchan! Please, wait!” Izuku shouted. Katsuki, hearing heavy footsteps behind him, started to run. “Leave me alone, Izuku!” He shouted, breathing, picking up from how fast he was running.
Katsuki rounded the corner, reached his house, and opened the door quickly, closing it behind him and leaning his back against it. A hand banged on the door, “Katsuki, please…” He heard Izuku plead from the other side of the door.
An alarmed Mitsuki rushed to the door, seeing Katsuki leaning against it, eyes watering, staring at his mom. All the pieces started clicking in Mitsuki’s mind. His son not fighting back as often as he used to, the state his son was in, and how much he had avoided going outside all made sense to her now.
Mitsuki sighs, ushering Katsuki inside with her hand. Her son slowly pulled away from the door, then sprinted to his room, a sob wracking his body. Angered by the way his pup was feeling, Mitsuki opened the door harshly. There stood the alpha, hair disheveled, eyes sunken, and his scent spilling out of him, smelling like acid.
“Izuku, what do you want?” She angrily spat. “Mrs.Bakugou, please. Let me just talk to him, please? I-I need to set things straight. I know this isn’t the best way to see me again, but please, just, just let me talk to Katsuki. I didn’t mean to hurt him – you know that. Please, just this once. I just need to get him to listen.” The alpha begged, tears threatening to spill as he slowly went down onto his knees, pleading.
“Fucking idiots.” Mitsuki exasperatedly said, pulling Izuku up and hugging him. The alpha was frozen in the hug. “Izuku, you’re a fucking idiot. You hurt my pup, you made my pup call me fucking Ma after years of not hearing that from him, and then you bang on my door like you deserve to talk to him.”
Hearing Mitsuki’s words, Izuku sobbed, “I-I’m sorry. You know I had to leave him. You know why, Mrs.Bakugou.” He shakily said, “I do. That doesn’t make it better, Izuku.” She said, pushing Izuku away from the hug and holding him at arm’s length.
“I have no idea what you did, what happened, but this was not the plan, was it?” She asked, still angry. “Yeah…” He hung his head in shame, “I didn’t mean for things to go this way, Mitsuki. I swear.”
“I’m going to let you go upstairs; his door is probably not locked. I will be leaving the house to go visit your mom, and you, Alpha, set things straight with my son, or your whole career and life will be ruined by me. Understood?” Mitsuki’s eyes turned into slits as she threatened the alpha.
“Yes, alpha. Thank you.” Izuku wiped his eyes, took a deep breath, and headed upstairs. He didn’t dare question Mitsuki, knowing the older alpha would genuinely hurt him if he failed to woo her son one more time.
He didn’t dare knock on the door anymore. Izuku let himself inside Katsuki’s room, seeing the blonde face down on his bed as he sobbed. Izuku’s heart ached to see Katsuki sob.
“Mom?” Katsuki questioned, lifting his head slightly to look at the door. “Get out.” He growled, throwing a pillow in Izuku’s direction.
Izuku caught the pillow, walking slowly towards Katsuki. “Sweetheart, please let me explain…” He trailed off, kneeling beside Katsuki’s bed, near his head.
Not getting a reply, Izuku sighed, “I left you seven years ago because your mom didn’t approve of me.” Izuku started off, he looked down at his hands, “I get her, I was in med school, you were, what, 13? She noticed that I started taking a liking to you, being an alpha and all, it wasn’t right. I agreed. I knew it was wrong, and my alpha wanted to be with you so badly. It got to a point where things started escalating, and my alpha was getting worse. I was scared for you, so I told Mitsuki and left.” He explained, voice shaking in nervousness.
“What do you mean?” Katsuki asked, muffled as he was still face down on the bed. “My alpha wanted to impregnate and claim you, Katsuki.” Izuku said, “I- fuck, I was disgusted with myself. You were a child, for fuck’s sake. There was no fucking way I’ll hurt you that way, Katsuki.” Disgusted, Izuku’s nails dig into his skin.
“Why not?” Katsuki questioned, lifting his head up from the bed. “Huh?” Izuku looked up, eyes widening at Katsuki, “Why didn’t you claim me? Impregnate me? I wanted you, Izuku, even if I was young, I wanted you.” He asked, no emotion in his voice.
“It’s because I was a beta, right?” Katsuki chuckled humorlessly.
“I-I mean, fuck, Katsuki, you were 13! A child! I was a grown adult, and I wanted to impregnate you! Someone who can’t get pregnant! My alpha could’ve killed you!” Izuku shouted, agast by the way Katsuki was pushing his buttons.
“You’re a fucking coward, Izuku. An idiot, Deku.” Katsuki spat.
“What do you want me to do, Katsuki? Fucking hurt you?” Izuku cried out, hands flinging into the air as he tried to make sense of Katsuki’s arguments.
“Fuck you, Izuku.”
“I’ve had enough of this, Katsuki! Are you hearing yourself? What am I supposed to even do? You were a child, and your mom was right! I can’t just impregnate you! You’re a fucking beta!” Frustrated, Izuku stood up, pacing.
“You teach embryology, figure it out, Izuku.” Katsuki pushed, “That’s not how it fucking works, Katsuki.” Izuku growled, eyes glowing, slowly losing control of his alpha as he was constantly ticked off.
“I know my dad paid you, Izuku,” Katsuki shouted, now standing up, and, as if Izuku had been dumped in a pool of ice water, he looked at Katsuki, almost getting whiplash. “What?”
“I know my dad paid you a pretty penny to research how to make me pregnant, Izuku,” Katsuki said once again, calmer now.
“That’s not-” Izuku started, “Not what? Not what it looks like? Fuck off, Izuku.” Katsuki cut him off, now coming towards the alpha, gripping the collar of his shirt.
“My parents have the money, I am their only child, my mom didn’t fucking approve because it would hurt me, my dad did not give a fuck, so my mom begged to let you be the one to impregnate me, seeing as I already took a liking to you for some stupid fucking reason, don’t fucking lie to me.” Katsuki spat, voice threateningly low as he stared at the alpha, nose almost touching.
“How?” Izuku asked, scared of his own voice, “I’m not an idiot, Deku. I was awake when you all started talking about me behind my back.” Pushing Izuku away, Katsuki sat back on his bed, taking a deep breath.
“I know my dad was behind all this. My mom being an alpha and him being an omega, then they pop out with a beta child, it doesn’t look good for the business, hell, it doesn’t look good for their image. My mom loves me; I know that. My dad’s was conditional. So seeing his son with an alpha who was eager to be with him, my dad manipulated, no, fucking blackmailed both of you to let him.” He explained. Izuku stood still, just staring at him with pained eyes.
“Katsuki…” Izuku started, kneeling in front of Katsuki again, gripping the man’s knees. “How much do you know, Katsuki?” Izuku asked, scared. “You would’ve never finished med school if you didn’t take the money, so you left. Then, when you started being a lecturer, you found out that one of your co-professors was an underground agent, you and Mom placed a hit on Dad.” Katsuki took a deep breath, “Lo and behold, dad died, and then you were suddenly my professor,” Katsuki said, emotionless.
“Katsuki, I’m so sorry. Please, Mitsuki and I just wanted you to be safe.” Izuku explained, desperation lacing his voice.
“Why do you think I’m still giving you this chance, Izuku? After that bullshit you pulled with Ochako?” Katsuki questioned, raising his voice.
“I only did that to make you jealous…I-I’m sorry…” Izuku explained, head hung low.
Katsuki said loudly, “You know what?” Izuku lifted his head. Suddenly, a slap rang through the room.
Katsuki slapped him.
“You deserve that, Izuku.” Katsuki spat, “I know, baby.” Izuku replied. Silence took over the room as they stared at each other.
Izuku cleared his throat, still unmoving from his position on his knees, cheek red, “Your dad was planning to sell you off, Katsuki.” He whispered, “I know.” Katsuki swallowed the lump in his throat. “That’s why you and mom did that, I know.”
“How?” Izuku asked, “Aizawa Hitoshi, Aizawa-sensei’s son, is my friend, Izuku.” Katsuki explained, “Oh.”
“I’m sorry, Katsuki.” Izuku apologized, lowering his head, forehead resting on top of Katsuki’s knees.
“Lift your head, Izuku.”
As Izuku lifted his head, Katsuki slapped him again. “That’s for making a fool out of me, Izuku.”
“I deserve that.” Izuku chuckled, biting his lip. “You do,” Katsuki said with a smile.
“Am I forgiven now, sweetheart?” Izuku asked hopefully, “Not until you impregnate me, Alpha.” Katsuki huskily whispered, cupping Izuku’s face.
Izuku’s eyes widen, “W-What…?”
“I know you found out how to turn a beta into an omega, Izuku. I know you want to impregnate me, so do it, Izuku.” Katsuki taunted, biting his lip and slipping his thumb inside Izuku’s mouth.
Izuku’s eyes darken, “Fuck, not here, sweetheart.”
“Why not? Mom gave you an opening, Izuku. I know she left, I know your whole plan.” Katsuki urged, “What do you mean, Katsuki?” Izuku asked, shaking, eyes dark as he tried to hold back his alpha.
“I collect the mail every day, Izuku. I’ve seen your letters for mom, and I think you both also wanted me to know.” Katsuki smirked, “Get me pregnant, you stupid fucking, alpha.” He taunted again, slightly slapping Izuku’s cheek.
Growling, Izuku stood up, “Fuck you, Katsuki. I’m not fucking you, not outside my den, I’m not that shitty of an alpha.” He growled, “Then take me to your den, alpha.” Katsuki bit his lip, leaning back on his elbows.
Izuku snarled, picking Katsuki up and taking him outside. They walked hand in hand with only their phones to Izuku’s car, which was parked along the road near Inko’s house. People pass them, staring at Izuku hungrily as the alpha let out aroused pheromones and shooting Katsuki jealous glances as he was basically dragged by the alpha.
As they neared Izuku’s childhood home, they saw Mitsuki and Inko standing outside the door. Mitsuki was smirking, winking at Katsuki while Inko just smiled warmly.
“Fuck you, Hag! Setting me up with an old man!” Katsuki shouted, Inko just laughed, “I know you like it, brat!” Mitsuki shook her head, laughing. He looked back at Izuku, who was now panting, opening the passenger-side door, his eyes fully glowing. “In, omega.” He growled, “Not yet an omega, fucking, Deku.” Katsuki snarled at him, but followed the alpha’s orders.
This was going to be a long ride…
—
The car stops as they reach a tall condominium building in the middle of the city. Izuku turns his car to enter the underground parking, and the lighting hurts Katsuki’s eyes. After Izuku parks, the passenger side door was ripped open, Izuku’s alpha still up front. The whole car ride was silent. No one was talking, and all that you could hear was Izuku panting as Katsuki teased him by caressing his thigh.
Katsuki’s feet didn’t even reach the ground when he was plucked up by Izuku, thrown over his shoulder like a sack of potatoes. The beta just laughed, shaking his ass to rile Izuku’s alpha more. They went inside the elevator, which had two people: one an alpha, the other a beta.
Katsuki made eye contact with the alpha, who was looking at them with a bewildered expression, “Hi alpha ~” Katsuki said seductively. The alpha backed away as Izuku growled so loud it shook even the other betas. Katsuki only giggled as the alpha smacked his ass.
“Oops…” He trailed off as the alpha and beta went down to their respective floors, leaving Katsuki and Izuku in the elevator alone. The alpha was still not talking to Katsuki, feral with need.
As they reached the penthouse, Izuku opened the door with a fingerprint and beelined into what Katsuki assumed was the bedroom. He was thrown onto the bed, bouncing.
Now that he was in the alpha’s den, Izuku’s alpha started to relax more, letting Izuku back up. “Kacchan, fuck, did I hurt you? H-how did we get here?” He asked, holding his head and pacing.
Katsuki ignored the pacing alpha, removing his clogs and lying down on the King-sized bed.
“Kacchan!” Izuku called to get his attention, “What? I’m literally fucking fine, Deku. Get to it, chop, chop.” Katsuki said, excitement lacing his voice.
“You’re fucking twisted. How are you so on board with this, Katsuki?” Izuku asked, narrowing his eyes at the blonde. Katsuki groaned, rolling his eyes.
Izuku just stood there, “You do know this would change your life forever, right, Katsuki?”
“I know, Deku. How many times do I need to tell you, drug me, fuck me, whatever?”
Izuku growled, reaching for Katsuki’s leg and pulling harshly, “You slutty fuck, I bet you let some bitch fucking cum in you already, huh?” He snarled, Katsuki laughed, slapping Izuku again, “And what if I did? What are you going to do about it, Alpha?” Katsuki taunted.
Izuku growled, flipping Katsuki on his stomach, pinning the blonde’s hand firmly on his lower back while Izuku took off his belt.
Once he finally got his belt off, he started looping it around Katsuki’s wrists to make a makeshift handcuff. Katsuki struggled against his hold, protesting that he didn't want to be tied down.
“I don’t give a fuck, Katsuki. Act like a brat, get treated like one, slut.” Izuku turned Katsuki back on his back, spitting on his face and slapping him lightly, making Katsuki whimper.
“Be good and obedient for me, sweetheart.” There was an evil glint in Izuku’s eyes as he said this, turning around and walking out of the room. Katsuki was left in the bedroom, surrounded by dim light. His eyes wandered around the room, making him gasp.
There was a shrine filled with pictures of Katsuki. Katsuki now regretted his decision to taunt Izuku. The motherfucker has pictures of Katsuki asleep with a dick on top of his face. He looked at least 16 in the picture, three years since he thought Izuku had left him forever. He rolled to the edge of the bed, trying to stand up without the help of his arms.
When he did, he walked closer to the shrine. Pictures of Katsuki when he was 13, 14, 15, until he was 20, he believes, the trimester before Izuku became his professor was pasted on the wall. Indecent pictures of Katsuki.
A picture of him passed out with his dildo next to him on his bed, a picture of him with his ass up after passing out from cumming to the thought of Izuku at 16, and more pictures of him with cum on his face, cum on his ass, fuck, even a finger pushing in cum inside his ass.
The door opened, snapping Katsuki out of the trance the shrine had on him. “What do you think, Katsuki?” Izuku asked in a sing-song voice. His eyes were different now; he looked insane.
“Fuck, Izuku, what are all these?” Katsuki was scared now, “Oh, this? This is my Kacchan shrine!” Izuku answered, smiling as he placed a syringe down on the nightstand.
“You’re fucking insane, Izuku.” Katsuki trembled as Izuku stalked towards him. “No, Katsuki, you wanted this, remember? ‘Impregnate me, alpha,’ you said…” Izuku trailed off, now holding a spreader bar he had gotten from under the bed.
“Shit, Izuku, will you kill me?” Katsuki was scared, backing away from Izuku, making his back hit the wall.
Izuku tilted his head, “Why would I do that, Katsuki?” He smiled insanely, “I would never hurt you, Kacchan.” He neared Katsuki, and this time, he raised his hand, trailing a finger from Katsuki’s cheek down to his neck, then to the area where Izuku would mark him, “I’ll make you my sweet, obedient wife…Fuck you full…Impregnate you…Make you cum drunk all day… every day…”
Katsuki stood frozen on the spot, swallowing heavily, “Izuku, please…”
“Please what, sweetheart?” There was a crazy look in Izuku’s eyes as he took in Katsuki’s trembling form. “I’m scared, Zuku…Please stop being scary…” Katsuki asked, tearing up in fear.
Izuku just smiled, then nodded, grabbing Katsuki by the forearm and leading him back to the bed. “I’m sorry, sweetheart…” Izuku tried to reassure the trembling blonde, rubbing his arms. “I’ll get you some water. I’m sorry if I scared you, my love.” Izuku apologized, excusing himself.
The alpha stood up and walked out the door. Katsuki sat on the bed, breathing quickly at the feeling of the belt still around his wrists. When Izuku got back with a glass of water in hand, he saw Katsuki hyperventilating on the bed.
“Kacchan? What happened?” Izuku worriedly asked, rushing to the blonde and placing the cup of water down on the nightstand.
“Zuku, off, take off the belt, please…”
Izuku quickly took off the makeshift handcuffs. When he did, Katsuki immediately wrapped his arms around Izuku’s neck, burying his face into the alpha’s neck. “C’mon, baby, drink some water.” Izuku offered, prying Katsuki’s arms off of him.
Naively, Katsuki took the offered glass. He suddenly felt lightheaded, and he fought the fog that was taking over his mind after swallowing the water Izuku gave him. “Zuku…What?” Katsuki struggled to ask Izuku what he had put into the water.
Izuku moved quickly. Suddenly, there was a prick of what felt like a needle. Katsuki can feel something flowing through his veins, making him itch. He was still paralyzed from what Izuku made him drink, eyes fluttering open and closed. The last thing that he saw was Izuku smiling on top of him, caressing his face.

Katsuki woke up feeling hot. He was hot all over. When he opened his eyes and tried to scream, “Shhh…That’s right, that’s my good little bride…” Izuku groaned.
The blonde screamed, trying to kick Izuku away but failing due to the spreader bar that held his legs apart, “Izuku, please, no more, alpha…” he cried out, desperately trying to push Izuku away. His hands were bound, connected to his legs, making him unable to move them.
“Shh, you’re okay, Kacchan,” Izuku squeezed out between moans as he fucks into Katsuki’s hole. Now more alarmed and aware, Katsuki looked down to where they were connected. Gasping loudly, “Where's my dick?” He sobbed out, struggling against the restraints.
“My pretty omega…” Izuku smirked, pulling out slightly then slamming back in, in full force. “FUCK!” Katsuki shouted, or moaned? Katsuki’s not sure now. Izuku smirked, holding onto Katsuki’s spread and bent legs, he started fucking into him harder, making Katsuki scream in pleasure.
“Alpha…Alpha, please!” Katsuki sobbed, not sure if he was begging to be set free or something else, “What do you want, my pretty omega?” Izuku asked, a manic smile appearing on his face as he fucks and fucks into Katsuki.
“Hngg…” Katsuki groaned, eyes rolling at the back of his head. “Fuck yeah, fucking squirt for me, Kacchan.” Izuku laughed, slowing down as he watched Katsuki squirt. Reaching forward, Izuku started rubbing Katsuki’s clit with his thumb, making the omega whimper.
When Katsuki started to relax once again, Izuku picked up the pace, not letting the omega rest. Katsuki was a screaming and crying mess. “Fuck! I’m close, baby. I’m going to make you a mommy, yeah?”
“Mommy…? No…Zuku…Don’t…” Katsuki said through his sobs. “Your fucking pussy thinks otherwise, Katsuki. Your soppingly wet fucking pussy.” Izuku fucks and fucks into Katsuki. The base of his dick starts to flare out as his knot forms.
“No…Zuku…Daddy…” Katsuki was in a daze, eyes rolling at the back of his head as moans spilled out of his mouth. Izuku suddenly pulled out of him, flipping him on his knees. Katsuki’s face was smushed on the bed.
“AHHH!” Katsuki screamed, scrambling to get away from Izuku as the alpha harshly shoved his finger into Katsuki’s pussy, finger-fucking him. A sob broke through Katsuki as Izuku pulled out of his pussy suddenly, making him squirt.
“Daddy, please!” Katsuki sobbed through his squirting, legs shaking, and back arching. “Fucking wet the bed, slut.” Izuku meanly spat, his hand connecting with Katsuki’s ass, once, twice, thrice, Katsuki doesn’t know now.
He was flipped back onto his back, the spreader bar and the ties on his wrists now removed. Izuku quickly positioned them into a mating press, pushing himself quickly inside Katsuki.
A long moan was pushed out of the omega as the alpha fucks into him roughly. His eyes rolling to the back of his head, tongue lolling out, and saliva dripping down his face. “My fucking slut.” Izuku slapped Katsuki over and over again, leaving the omega with red cheeks and brainless.
“Fuck! Get fucking pregnant, Katsuki!” Izuku growled out, pushing one last time as he forces his enormous knot into Katsuki’s new tiny pussy. The omega’s insides turn warm as Izuku’s cum floods his newly formed womb, moaning, Katsuki’s legs shook, his hole clenching hard on Izuku’s knot as if milking it as he cums.
Then a piercing scream came out of Katsuki as Izuku bit into his neck, injecting alpha venom into the new omega, followed by a loud moan. Making him pass out from the pain and the waves of pleasure engulfing his being.
Katsuki woke up again, this time he was on all fours, moaning like a bitch in heat. “You, awake, sweetheart?” Izuku asked between slams of his hip on Katsuki’s ass, “Y-yes…Daddy…More…C-cum…” Katsuki pleaded, brain fried from the amount of cumming he had done.
“In a bit, sweetheart, we’re just getting started,” Izuku replied, placing kisses on Katsuki’s back. “How many?” Katsuki asked, eyes crossing when Izuku hit his g-spot. “Cummed in you four times already, sweetness,” Izuku gathered some cum and slick from Katsuki’s frothing pussy, rubbing it into his asshole.
“Gonna let me fuck your ass, baby?” Izuku asked deviously, slowly inserting his thumb already, not waiting for Katsuki to reply. The omega just moaned, his ass slowly relaxing as Izuku used it as a way to hold onto him as he fucks hard.
The thumb was soon replaced by Izuku’s index finger, pumping in and out of the ass. Slick started to drip out of his asshole as Izuku continued to play with it. “Fuck yeah, I love fucking male omegas, slicking out of both holes, huh? What a good boy ~” Izuku praised, earning him a loud moan from the fucked-out boy.
Izuku added two fingers at once, stretching Katsuki’s ass further. “Daddy!” He squealed, then moaned as Izuku matched the pace of his hips and his hand, effectively frying Katsuki’s brain.
The alpha pulled out of Katsuki’s pussy, stuffing it with a pussy plug that he got from the side of the bed. Roughly inserting himself into the omega’s wet asshole, moaning loudly at the tight fit.
“So tight, sweetheart, never let anyone touch you, yeah?” He questioned, hand clamping down on Katsuki’s nape as he fucks and fucks into the boy. “N-no! Only d-daddy…” Katsuki drunkenly replied, drool creating a wet spot on the bed as Katsuki lost the ability to shut his mouth.
“Who owns you, Katsuki?”
“You, daddy!” Katsuki moaned out, pussy clenching on the plug and ass clenching on Izuku’s monstrous cock.
“What’s this hole called, baby?” Izuku whispered into his ear as he bent down, “My a-asshole?” Katsuki answered, unsure what the alpha wants. “Wrong,” Izuku smirked, pulling out of the hole but not completely.
“What’s it called, Katsuki?” He asked again, teasingly pushing in just the tip, then pulling out. The omega was now crying, shaking his ass as if trying to fuck himself on Izuku’s tip.
“I dunno, d-daddy! Please! P-put it b-b-back in!” He sobbed, shaking as his weak arms tried to reach behind him to hopefully push Izuku back inside him.
“It's called an asspussy, baby.” Izuku said, grinning down at the struggling blonde, “Say it, Katsuki, beg daddy to fuck your ass pussy.” Izuku spits on Katsuki’s face, his saliva traveling down to Katsuki’s closed eye.
Katsuki looked so messy, complete and utterly fucked out as he begged, “F-Fuck my asspussy, d-daddy! Please…Please…Please…” Sobs shook his frame.
“Good boy.” Izuku pushes back inside Katsuki, fucking into him at such a rough pace that Katsuki is pushed around on the bed.
“M’gonna fucking knot your asspussy, Kacchan!” The alpha moaned, slamming his hips down with so much force that Katsuki was sure that he could’ve broken the bed.
Izuku laughed, then stepped on the side of Katsuki’s head for leverage as he fucks harder into the omega’s ass. Loud moans fill the room, Katsuki gripping the sheets until his knuckles turned white, clawing at it, and even hitting the bed.
After a few thrusts, Izuku bullied his knot inside Katsuki’s asspussy, cumming so much that it spills to the side of the knot. He catches his breath, checking on Katsuki, who was now, again, passed out.
Izuku pulled out after a while, placing his biggest anal plug into Katsuki’s asspussy, the green jewel pairing perfectly with the orange jewel of his pussy plug.

Groaning, Katsuki sat up suddenly, “What…?” He whispered in confusion into the empty room. He was clean now and wearing what he believed was Izuku’s shirt, no bottoms, reaching up to his neck, and he felt the fresh bite mark. Scanning the room, he realized he was now sitting on fresh seats, with the curtains drawn to the side, allowing the sun to shine through.
The Katsuki shrine was still there; it wasn’t a dream. He felt a sore spot on his thigh. Looking around, he saw an empty needle on the nightstand. Katsuki knew Izuku used whatever that drug was on him. To turn him into an omega. And honestly, He didn’t feel mad. A weird feeling of contentment warmed him at the thought of now being able to be Izuku’s omega.
As he tried to get up, he felt something move inside of him. Moving the blanket to the side, he saw an orange jeweled pussy plug and a green anal plug inserted inside him, keeping him full. His hands moved down to caress his abdomen as it juts out from what he assumes was cum.
He bit his lip as his hand traveled lower, feeling his newly formed clit, his labia majora, then his labia minora, traveling further down to trace the stretch of the plug around his hole. Wetness leaked through the plug as Katsuki gets aroused, he lifted one leg up the bed, spreading himself wide open.
Katsuki started rubbing his clit, gathering wetness from his hole. His index finger started flicking his clit from side to side, moans spilling out of him as he played with himself. His other hand reaches up to squeeze and pull his growing tits.
Moaning loudly as he cums, squeezing down on the plug inside of him, pushing it inside his pussy further.
“Enjoying yourself, my love?” A voice coming from the door said, Katsuki blushed as he hurriedly closed his legs together, biting his lip to stop the moan from coming out of him.
Izuku came closer to him, hand caressing Katsuki’s head, making the blonde look up. “How are you feeling, my love?” He asked in a soft voice. Katsuki tried to speak, but his throat was too dry for any words to come out. Seeing this, Izuku bent down to reach for a glass of water on the nightstand.
Katsuki eyed the glass suspiciously, making Izuku laugh. The empty syringe next to the glass of water made Katsuki more nervous.
Izuku shook his head, chuckling, as he took a sip of the water first, then showed Katsuki that he swallowed the water. Seeing this, Katsuki snatched the glass of water off of Izuku’s outstretched hand and greedily drank. “Hey, slow down, baby.” Izuku sat beside him, rubbing his back.
Katsuki took a deep breath after he finished gulping down the water. He gently placed the glass on the nightstand, then turned to face Izuku.
“Zuku?” He asked in a quiet voice, “Yes, sweetheart?” Izuku replies, tucking a stray hair behind Katsuki’s ear, “Am I…Am I a mommy now?” He asked again softly, head hung low.
He heard Izuku chuckle, then a kiss was placed on top of his head, “I hope so, my love. I’m pretty sure you are.” Katsuki lifted his head up, “Why’d you do that to me, Zuku?” He asked, bottom lip trembling.
“I’m sorry for scaring you, sweetheart, I didn’t mean to scare you…” Izuku trailed off, peppering kisses around the man’s face to calm him. “You stalked me, Deku,” Katsuki led on with his voice trembling.
“You stalked me, but you didn’t let me know you wanted me. Why is that, Deku?” Tears forming again, he roughly wiped them away, annoyed by the fact that all he’s been doing is crying and crying over and over again.
“Y-you know I couldn’t let you know, Katsuki. Your dad was keeping an eye on both of us. I was only able to do all that when everyone was asleep.” Izuku explained, grabbing Katsuki’s hands that were rubbing his eyes, swapping them with his gentle wiping.
“Will you, will you leave me again?” Katsuki bit his lip, scared of the answer. Izuku just stood up, carrying Katsuki and making the blonde wrap his legs around Izuku’s waist. He felt Izuku walk, not sure where they were headed as he kept his face buried into the alpha’s neck, now being able to smell his musky-pine scent.
When he feels Izuku stop, he lifts his head, “Look, baby.” Izuku urged, shocking Katsuki as he found his clothes from both his dorm and childhood home lining Izuku’s walk-in closet.
“I stay?” He asked, lip trembling, then he wailed, throwing his head back. Izuku laughed, cradling Katsuki’s head and pressing a peck on his swollen lip.
“Of course, sweetheart. You are.” Katsuki hiccuped, Izuku touching his nose with Katsuki’s, looking into his eyes, he said, “I love you, Katsuki. Please mark me?” Izuku’s eyes shine with tears, mirroring Katsuki’s.
Nodding, Katsuki sank his teeth into the soft flesh of Izuku’s neck, completing their bond mark.

A few months later, Katsuki was walking through the halls of his college, hair longer, cheeks pinker, and with a new scent. People were staring at him as he walked towards his first class of the trimester.
Katsuki didn’t care; all he cared about was keeping the pussy plug and the anal plug inside him, making sure no cum was dripping down his thigh, hoping not to ruin the beautiful sundress Izuku bought him yesterday from Forevermore.
“What the fuck, Bakubro?” Kirishima stood in front of the classroom, mouth agape.
Oh, Katsuki forgot to tell him, he was now a mated omega and three months pregnant with twins. Smirking, Katsuki rubbed his prominent stomach, “Come on, class is going to start soon!” He laughed, pulling on Kirishima’s arm, leading him inside the room.
