“Kacchan!”
Bakugo bristled, glaring menacingly before his features softened, “Izuku.”
“I didn’t think you’d show up.”
“Yeah, well, I didn’t have anything better to do tonight.”
The annual UA alumni Christmas party saw many heroes return to celebrate and reunite with their former classmates. Izuku attended every single one, partly because he now taught at UA, partly because he still loved meeting heroes. He knew this was the first time Bakugo attended, and he had a feeling Kirishima and Kaminari begged him to show up.
The cold air surrounded them as they quickly made their way to the building, making short conversation- well, Izuku rambled on as Katsuki responded with grunts or one word answers. Izuku didn’t take it personally, he knew Bakugo disliked the cold and wet.
“Midoriya-chan! How’ve you been, ribbit?”
“Hello Tsu-chan!”
“Hey!” came a shrill voice, Bakugo and Midoriya stared as Ashido came bounding towards them, she pointed above their heads, “Mistletoe!”
They looked up in unison at the green shrub, “We’re both men! Not that there’s anything wrong with men kissing… I’m gay-,” Izuku rambled, “- I-”
Izuku’s spiral was short-lived as Bakugo placed a quick kiss on the corner of his mouth before hanging up his coat and scarf in the closet neatly and entering the party without a word. Izuku stood stunned as Ashido and Asui led him into the party, where he was immediately swarmed by Uraraka.
“You seem distracted,” Uraraka noticed, as Midoriya glanced around the room for the tenth time in five minutes.
“Huh? It’s nothing,” Izuku muttered, a faint blush dusting his cheeks.
“Nothing?” Ashido slung her arm over Uraraka’s shoulders, whispering conspiratorially, beckoning her closer, “Bakugo kissed him under the mistletoe!”
Uraraka let out a delighted squeal, “That’s great news, I know you’ve been crushing on him since forever!”
“It’s not like that!” Izuku hissed, “We just happened to walk in together when Ashido-san spotted us! I didn’t know there would be mistletoe there!”
“Oh…” she deflated, “We’re adults now, you can tell him how you feel.”
“I can’t. I don’t know if he likes men... Or omegas,” he responded, defeated.
Ashido squished his cheeks together with her palms, “Hey, none of that, if Bakugo didn’t want to kiss you, you know he’d blast you and that mistletoe straight to hell.”
Izuku knew he had too much to drink, swaying to the music with his friends. He had lost track of Bakugo hours ago, he probably left without a word to anyone. Izuku downed another glass of champagne before Iida gave him a disapproving frown, “You’re cut off, Midoriya-san.”
“What? Why?” he whined.
“Because you’re drunk. You should go home and rest. The party’s winding down.”
“I’ll help with the cleaning up-”
“No need,” Iida waved him off, “Let me get someone to take you home safely-” he surveyed the dwindling crowd for someone sober enough- “Bakugo-san! Please escort Midoriya-san home.”
“Yeah okay,” he responded, an eyebrow raised at Izuku’s drunken state, “C’mon nerd. Let’s get your coat on.”
Izuku waved goodbye to Iida as Bakugo led him to the front door, helping him into his coat before quickly putting on his own.
“Kacchan!”
“Hmm?”
“Mistletoe!”
Bakugo paused, staring at the shrub again, fingers pausing momentarily as he tied his All Might scarf securely around his neck.
“Yeah I see it, Izuku.”
“Mistletoe, Kacchan!” Izuku repeated, pouting.
“You’re a brat when you’re drunk,” Katsuki sighed, his hand carefully reaching for Izuku’s cheek, pressing a gentle kiss on Izuku’s mouth. Izuku’s happy pheromones spread, clearly pleased with himself as Katsuki drove him home.
Midoriya leaned heavily against Bakugo as he swiped his key card to his apartment. The door beeped once, locks disengaging as Bakugo opened the door, helping the omega in. He wrestled a wriggly Izuku out of his coat, hanging it neatly on the coat rack and helped the omega out of his shoes.
“Bed time~” Izuku laughed, stumbling through his apartment, Katsuki was not the least bit surprised that Izuku’s apartment resembled a hero merch shop; large posters of All Might on every wall, glass display cabinets meticulously housed figurines, keychains, and pictures of All Might and other heroes.
“Oi! Be careful!” Katsuki yelled, dashing forward to stop Izuku from falling. He giggled as the hero lifted him bridal-style, “Where’s your bedroom?”
“Kacchan, help,” Izuku whined, clearly struggling with the button on his pants in the dark room. Katsuki rolled his eyes, helping the teacher out of his jeans and wrapping him snugly in a blanket from his nest. Izuku purred happily, hand gripping Katsuki’s scarf tightly when he settled the omega into his nest.
“Careful, you’ll rip my limited edition All Might scarf!” Bakugo hissed, but Izuku was already asleep. Sighing, Bakugo untied his scarf, leaving the sleeping omega to nuzzle against it.
“I better get that back,” he muttered, looking around the dark room only to find a life-sized, laminated poster of himself on the wall next to Izuku’s nest.
Bakugo blinked, head tilting. He remembered that picture, it was from the photoshoot he was forced into when he made it into the top ten hero ranking: he was shirtless, hero mask on, pants low on his hips, gauntlets off, gloved hands with both middle fingers up, wearing a cocky smirk, red eyes glowing with contempt. Bakugo wore a matching smirk, feeling smug that his picture was definitely the first thing Izuku saw every morning and the last thing he saw every night. Absent-mindedly, he felt sorry for whichever alphas Izuku invited into his nest.
He exited the omega’s bedroom, deciding that a little snooping wasn’t going to hurt anyone as he fanboyed over Izuku’s extensive All Might collection. He noticed display cases which housed official merchandise for each of their hero classmates, along with framed class pictures. Although Bakugo never released official merch, there was an empty case neatly labeled ‘Great Explosion Murder God Dynamight’. Eyes drifting downwards, he spotted Izuku’s old notebooks filled with his hero notes.
Two heavy binders lay neatly on his coffee table, Bakugo settled on the couch, pulling the one closer to him. He flipped it open and smiled. Some things never change, he mused, reading detailed notes of all of the current heroes. Izuku was thorough, including newspaper clippings, pictures from fan meet and greets, autographs, and even scent profiles to his binders. It didn’t escape him that he was definitely not included in Izuku’s main hero binder, as he snapped it shut, reaching for the next binder. Opening it, he suddenly realised why. Izuku had created a separate binder just for him, there were sections where Izuku’s neat handwriting explained why they were sparse, ‘Kacchan never released official merch’, ‘Kacchan never has fan meet and greets’ next to pictures of informal fan meetups, polaroids of Izuku smiling broadly as he posed next to a cardboard cutout of Bakugo. A blank page headed ‘Autograph’ with a sad smiley face, also caught his eye. Bakugo flipped through the many articles and pictures of himself neatly entered into Izuku’s binder.
Scent Profile: Intoxicating campfire. Sweet undertone when happy - s’mores? brown sugar? Bakugo frowned, deciding to edit the sections as he picked up a nearby pen.
Izuku stumbled out of bed the next day, still wearing the soft sweater he wore to the party. Memories flooded back to him as he remembered asking Katsuki for kisses and to help him take off his pants. Groaning in embarrassment, he hoped Katsuki didn’t notice the poster he kept in his nest. He brushed his teeth and showered, dressing comfortably for his day as he walked into his living room. His eyebrows furrowed in confusion, he was sure he put his hero binders away before the party. Dread crept in as he looked at his Dynamight binder splayed open.
Fuck.
Katsuki had definitely seen it. With trembling hands, he pulled the binder close, reading the black inked edits.
Scent Profile: Intoxicating campfire. Sweet undertone when happy - smores? brown sugar? CARAMEL
As he flipped through the pages, smiling as he read Bakugo’s quips and edits, a proper Dynamight autograph greeted him - the only autograph Bakugo ever gave.
‘To my biggest fan, Izuku
Go beyond! Plus Ultra!
Great Explosion Murder God Dynamight’
There were small doodles of sticks of dynamite and explosions littering the page. The sad smiley face was scribbled across. Izuku’s heart swelled from joy, and if he spent the rest of his day looking at that autograph, no one would have to know.
“Can I help you?” the young woman drawled.
“Hello, yes. I’d like to see Dynamight please.”
She blinked at him slowly, “Dynamight-sama does not meet with fans.”
“I’m not a fan- Well, I am, but that’s not the point. He knows me. I’m just here to return something to him!” Izuku explained.
The woman rolled her eyes, sarcasm dripping from every word, “Sure you are.”
“Call him, he’ll tell you!”
“You need to leave.”
“What? No!” Izuku fretted, clutching the bag tightly, “I need to return something to him.”
“Midoriya?” Izuku turned to find Kirishima just returning from a patrol, “Is everything okay?”
“Welcome back Red Riot-sama,” the woman welcomed, “This man is trying to see Dynamight-sama.”
“Oh? Well I’ll take you to meet him.”
“Are you sure that’s fine?” she questioned.
“Why wouldn’t it be?” Kirishima laughed, dragging Izuku further into Dynamight’s hero agency.
“Thanks Kirishima-san, I was very close to being thrown out.”
“Bakugo made it very clear that he wasn’t going to meet fans, so the reception staff are trained specifically for that. Here we are,” Kirishima knocked once before opening the door.
“Bakubro-”
“Shitty Hair! Why the fuck would you knock if you’re not waiting for a response?!”
“-Midoriya is here to see you.”
Bakugo’s eyes focused on the bag Izuku was holding, “That better be my All Might scarf.”
“It is!”
“Did you have lunch yet Midoriya?”
Izuku shook his head, “I wasn’t planning on staying long.”
“Stay here, I’ll go pick up lunch for you and Bakugo. I’ll be back soon,” Kirishima stated, staring pointedly at Bakugo before running off.
Izuku closed the door behind him and approached Katsuki, carefully handing the scarf over, “I washed it.”
“Huh? Why is it completely scentless?”
“I used heat-grade detergent, sorry, it’s the only kind I had on hand,” Midoriya explained, tips of his ears turning red.
“Right…” Katsuki responded, clearly hesitant.
Izuku refused to meet his eyes, opting to sit primly on one of the couches in the office. Izuku couldn’t tell Bakugo he accidentally got slick on his scarf…
After reading Bakugo’s edits, Izuku went back into his nest, grabbed the scarf and inhaled deeply… There was a caramel undertone! Bakugo’s scent never failed to get Izuku riled up, his rich, intoxicating scent and the picture of a cocky Bakugo staring down at him immediately made him slick up. When Izuku came to his senses, he had slicked all over Bakugo’s scarf. Simply washing it wouldn’t get rid of the evidence, he needed to bring out his heavy-duty heat cycle detergent…
“-zuku? IZUKU? NERD, ARE YOU DEAF?”
“Sorry, what did you say?
“I said, ‘Are you planning to just stare at the wall?’”
“Yes. What else is there to do?” Izuku asked, looking around Katsuki’s minimalist office.
Bakugo stood up suddenly, “Come with me. This should keep you occupied.”
Izuku followed him through an impressive security door. Izuku blinked, not believing what he was seeing… Every iteration of Katsuki’s hero uniform was carefully preserved in glass cases, his gauntlets, gloves and accessories were all laid out and labelled, sketches for new iterations were pinned to the wall… Izuku was in Dynamight-heaven.
Katsuki went back to his paperwork, the quiet was broken only by Izuku’s fanboy muttering.
Later, Midoriya got home with his stomach full, and dinner plans that week.
“Delicious food, Kacchan’s company… This feels like a date,” Izuku giggled, a little tipsy from two glasses of wine.
“It is,” Katsuki replied easily.
Izuku chuckled to himself, “Sure Kacchan~” he sobered up for a second, looking at the blond intensely, “This is another dream again. Isn’t it?”
Before Katsuki could reply, Izuku dropped his wine glass, waiting to watch it shatter on the floor. Katsuki’s reflexes kicked in, snatching the glass from the air before impact, “What the fuck Izuku?”
“I knew it!” Izuku squealed triumphantly, “It didn’t break because this is a dream!”
Katsuki sighed, mentally noting to keep Izuku away from alcohol in the future, “C’mon, let’s watch a movie.”
“This is taking really long,” Izuku commented as the movie started.
“What are you talking about?” Katsuki responded, eyes leaving the All Might documentary to glance at Izuku.
“This isn’t how it usually goes.”
“Are you feeling alright? It always starts like this,” he gestured at the television as All Might was being interviewed.
Izuku rolled his eyes, “Not the documentary, the dream!”
“How does it usually go?”
Izuku promptly climbed into the blond’s lap, straddling him, causing Bakugo’s breath to hitch as the comforting weight settled across his hips, “Usually, you’re all over me…” his hands roamed Katsuki’s pecs, hiking up his shirt and running his fingers over every muscle, “Very detailed,” he commented as fingertips grazed the scar in the middle of his chest, “By now, you’d have me pinned down…”
He shifted his weight, moving to yank the blond’s shirt off when his elbow knocked into the television remote. It fell with a soft clatter, a battery rolling under the coffee table. Izuku stilled, sobering up at once, face getting redder by the second. His hands flew to cover his face, peeking between his fingers to look at Katsuki as he realised he was in fact not dreaming, “I’m so sorry Kacchan.”
He stammered out excuses and apologies, climbing off the alpha. They sat in an awkward silence for a second before Izuku spoke again softly, unsure, “Were you serious when you said this was a date?”
“Yes.”
“W-With me?”
Bakugo rolled his eyes, “Is there anyone else here?”
“You asked me on a date?”
“Oi! What’s that supposed to mean?”
“You’re you…” Izuku tried to explain, “and I’m… me… Kacchan, do you like me?”
Katsuki stared at the teacher in disbelief, “Yes. What aren’t you understanding?”
Izuku stood suddenly, “You,” pointing at a confused Katsuki, “Like,” he pointed at himself, “Me?”
“Are you concussed?”
Izuku sat down on the sofa, head in his hands, whispering to himself, “Kacchan likes me.”
“D’you got a problem with that?!”
“Does this mean you’re going to court me? Marry me? Mate me?”
Bakugo stared at him, bewildered. He wiped a hand across his face, “I wanted to start courting you immediately, hell, I already have your courting gifts, but I didn’t know if you thought of me as just your childhood friend… I asked you on a date to gauge if you’d want to be courted by me.”
“I do!” Bakugo looked into Izuku’s hopeful green eyes, the omega grabbed his hand and nuzzled his cheek against it, “I want all of it with Kacchan! Court me!”
Katsuki nodded, “Okay!” He stood up, “Wait here.”
Katsuki returned within minutes with two very large, ornately wrapped gifts. He set them in front of Izuku who was practically vibrating with excitement.
“Will you accept my courting gift, Izuku?”
Izuku lunged, arms wrapping tightly around Katsuki’s neck, “Yes!”
Katsuki kissed him until he was dazed.
The alpha chuckled, “You haven’t even opened them yet.”
“I don’t need to open them to know I’ll love it.”
Bakugo rolled his eyes, placing the larger box in front of the omega. Izuku carefully unwrapped it, squealing as he removed massive, plush blankets decorated with tiny explosions and Dynamight’s signature orange and black fins, as well as his green and silver grenade gauntlets.
“I washed them already so you can put them in your nest.”
Izuku’s eyes widened, purring as he rubbed his cheek against the soft material.
“Scent them,” he demanded as they settled on the sofa again. Katsuki smirked, taking the blankets and scenting them as Izuku continued unwrapping.
“Oh, I’ve always wanted an omega box,” he muttered, pulling silk pyjamas, hoodies and other Dynamight-themed apparel from the box, piling them high on Katsuki to be scented. As he reached the end, he pulled out the final box. Katsuki was beaming with pride, chest puffed seeing Izuku’s excitement. Izuku opened the slender box, and shook it once, its contents falling on his lap. They froze. Izuku picked up the Dynamight-themed dildo carefully. It was a modest seven inches of black silicone with orange accents, with a suction cup at the base. He looked at Katsuki who was staring in confusion.
“What the fuck?”
Izuku laughed, “These come with omega boxes, Kacchan. Usually it’s a custom mold…”
Katsuki remembered blasting the mold kit to smithereens when he received it, “I didn’t submit my measurements.”
“Oh, then this is the default one, I guess.”
Izuku put the dildo back into the box neatly, standing to open the other gift. He stilled as he peered into the box, breath catching loudly. He looked at Katsuki with wide, watery eyes, “Is this what I think it is?”
Katsuki smirked as Izuku pulled out a perfect replica of Dynamight in his full hero costume.
“The only official Dynamight merch ever.”
Izuku shrieked in glee, carefully turning the box over and intently reading every word printed. He carefully placed it on the coffee table as he looked at the other merch in the box. He treated each model and figurine with reverent care, fingertips brushing over the #001/001 embossed on each box.
“Kacchan, this is amazing. Thank you, I love it all.”
“You can finally fill up that display case.”
Izuku’s smile was blinding.
Katsuki drove Izuku home that night, helping him with the massive boxes. Izuku insisted on adding the blankets to his nest immediately, purring loudly as he fixed it to his liking. The blond smiled, “You should get some rest, you have that big test tomorrow. I’ll let myself out… And I’ll pretend that I can’t see that picture hanging in your nest.”
Izuku let out a scandalized gasp, launching a pillow at Katsuki’s head with precision. Bakugo laughed, batting the soft projectile away effortlessly, “See you soon, ‘Zuku.”
Bakugo made it three steps away from the front door before he felt a hand wrap around his wrist.
“Stay…” Izuku whispered, eyes gleaming.
Katsuki brought a gentle hand to the teacher’s chin, tilting his head upward, “Okay.”
Midoriya closed his eyes, nuzzling against Katsuki’s warm hand before leading him back to his nest.
“Make me yours.”
Izuku whimpered as Katsuki undressed them both, “Hey, don’t hide from me. What’s wrong?”
Izuku covered his face with his hands, “Are you sure you want me?”
“Huh? Why wouldn’t I want you?”
“Because… Because I’m not like traditional omegas… Y’know, the pretty, petite ones with the unblemished skin…” Izuku trailed off, voice thick with emotion.
“You’re the only person I’ve ever wanted. I love that you’re strong,” Katsuki reassured, kissing Izuku’s scars, slowly making his way down Izuku’s body, “You sacrificed yourself to protect the world.” The blond leaned forward to kiss Izuku softly, “You’re gorgeous… The most beautiful man in the world.”
“Kacchan-”
Katsuki lay between Izuku’s trembling, thick thighs, tongue slowly dragging across the omega’s clit, reveling in every sound that escaped his lips.
“Kacchan, please. I need you.”
“You have me, Izuku.”
Izuku could feel Katsuki’s lips move languidly against his dripping pussy, clearly enjoying himself.
“You know what I mean!”
“Do I?” Katsuki asked, gently nibbling on Izuku’s clit before pressing a soft kiss against it.
“Please. Kacchan. Please.”
The blond cocked an eyebrow, red eyes focused intensely on every move Izuku made.
“I- I can’t- Kacchan, I’ll cum if you keep doing that,” he whined, fingers tightening in spiky blond hair.
“Then cum.”
“No! Please-” he yanked hard on Bakugo’s hair “-Wanna cum on your knot. Please fuck me alpha!”
Never one to disappoint, Katsuki immediately sprang into action, spreading Izuku’s legs wider, “I’ll play with your pretty pussy some other time then.”
Izuku nodded dumbly as Katsuki lined himself up with the omega’s dripping hole before sliding in one smooth stroke.
“So big Kacchan- You’re in so deep… I’m not going to last,” Izuku whimpered as Katsuki fucked into him, slow and deep.
“You feel fucking amazing. You were made for me, Izuku. Gonna knot you, cum for me, sweetheart.”
Izuku came with a cry, thighs shaking as Katsuki knotted him.
“Feels so full. Bred me so well, Kacchan,” he slurred as Katsuki kissed him deeply. Wrapped in the comfort of Bakugo’s arms and scent, Izuku quickly slipped into sleep.
Izuku woke to the gentle rays of sunlight streaming across his face. He stretched, moaning as his joints cracked pleasantly.
“Good morning Kacchan.”
“Good morning ‘Zuku.”
There was a pause before the omega sat upright in his nest, memories of last night rushing into his head, “Kacchan?!”
“Why are you surprised?”
Izuku didn’t respond, burying himself into his new blankets. He peeked at the blond who was only dressed in underwear and an apron.
“Wait- Were you greeting that poster?” his lips twisting into a smirk as he observed the reddening omega, “It’s seven. Didn’t you have to get to work early?”
Izuku yelped, jumped out of bed and ran to his bathroom to quickly shower.
“Aren’t you forgetting something?”
Izuku opened his bag, peering in at the perfectly wrapped bento box Katsuki made him for lunch. He thought for a second, mouth dropping open in horror, “I forgot the exam papers at home!”
“No dumbass,” Katsuki hissed, “Wouldn’t that be in the staff room?”
“Oh right,” Izuku calmed down, observing the way Katsuki pouted, “Oh I remember now, Kacchan-” he leaned across the seat to place a gentle kiss on his alpha’s cheek.
Bakugo’s face was red as he tilted his face to capture the teacher’s lips in a kiss. Izuku’s hands reached across, fingers threading through soft, blond locks, deepening the kiss.
“You should call in sick,” Bakugo suggested as Izuku’s tongue licked into his mouth, kissing him filthily, “We can continue last night’s activities…”
“Don’t tempt me. I should go… The last thing students need to see is their teacher making out in a car like a horny teenager.”
“One more kiss before you go.”
Izuku smiled brightly at him before granting his request, “I’ll see you later?”
“Yeah.”
Bakugo was eating his lunch when his door slammed open, Kaminari sauntering in.
“What the fuck do you want, Dunce Face?” Bakugo asked, not even bothering to look up as the Kaminari leaned against his desk.
“Nothing, Bento-Box-Bakugo-sama,” he smirked.
“The fuck did you just call me?”
Kaminari didn’t respond, fidgeting on his phone before showing the screen to Bakugo.
There was a picture of the bento box Bakugo had packed for Izuku, captioned with a heart emoji and a dynamite emoji. Katsuki’s eyes flitted to the account name - Deku-sensei.
“What’s the blue tick mean?”
“Verified account. This picture has been going viral,” Kaminari explained, showing the comments to Katsuki.
There’s no way GEMGD did this.
Are you being courted by Dynamight?
This is so freaking cute! I love you @Deku-sensei.
“There’s a lot of tabloid coverage on this,” Kaminari added, swiping through other pages, reading aloud, “‘Dynamight courting Deku?’, ‘Deku’s Mystery Alpha?’, ooh and my favourite one ‘[EXCLUSIVE] Dynamight’s Explosive Love Confession!’” Kaminari snorted, doubling over as he laughed, “You really should join social media, that way you’d be in the loop.”
“Hard pass, why would I care about what extras think?”
“Baku-bro! I just saw the news! Congrats bro!” Kirishima shouted, strolling into the office, clapping him hard on the shoulder.
“It’s time for our workout!”
“I’m busy, Ei. Fuckin’ mayor wants a fuckin’ damage report on the villain attack downtown. I’m not moving from this desk until I’m finished,” Bakugo groaned, dragging a hand across his face in frustration.
“Tomorrow then?”
Bakugo grunted, fishing out his vibrating phone from his pocket as his friend left. His frustration dissipated as he read Izuku’s message.
Izuku [4:01pm]:
I love the nesting materials. It’s soooooo soft and it holds scents really well!!!! I’m enjoying everything from your courting gifts.
Bakugo preened, ego inflating with pride, busy typing out a ‘Glad you liked it’ message when another message from Izuku came in. He tapped the photo to download, prepared to see Izuku bundled up in his nest, or a cute selfie. When the picture downloaded, he stood so quickly, his chair slammed against the wall with a loud bang, phone gripped tightly in his hand, palms heating up as he looked at it: the Dynamight-themed dildo dripping with slick, suctioned to what looked like the poster of himself that was in Izuku’s nest. He deleted his response, quickly typing out ‘Leave your balcony door unlocked.’
Grabbing his mask, he practically ran out the door, nearly crashing into Kirishima in the corridor as he sprinted up the staircase to the roof.
Bakugo entered Izuku’s bedroom through the balcony door minutes later, watching intently as Izuku moaned, rocking back against the poster. The squelching of slick and the back of his wet thighs unsticking against plastic punctuating the silence as the omega’s scent permeated the room thickly.
“Oi, Izuku.”
Izuku’s eyes focused on the man in front of him, decked out in his Pro Hero outfit, “Kacchan?”
“No,” Bakugo corrected, climbing into his omega’s nest, “Dynamight.”
“Fuck… Dynamight-sama,” he whined.
“I didn’t know that the famous Deku-sensei was a fuckin’ hero groupie,” Bakugo taunted, cupping Izuku’s face tenderly, thumb pressing into the omega’s mouth.
Izuku nodded dumbly, keeping his rhythm going, “Always wanted you, Dynamight-sama, wanted you to split me open with your fat cock… Pump me full of your cum… Wanna hang off your knot…”
“That can definitely be arranged, sensei,” Bakugo confirmed, tugging his pants down to free his cock. Izuku whimpered as the blond’s cock pressed against his cheek, smearing precum across his lips before gently sliding into the teacher’s mouth, easing down his throat until Izuku’s nose was pressed against the Pro Hero’s skin. Bakugo groaned as Izuku’s wet, hot mouth, worshipped his cock, taking every inch with reverent care.
The omega wasn’t done there, setting up a slow pace, alternating filling himself up with the dildo as he suckled on the head of Katsuki’s cock, then sliding off the dildo and deepthroating his alpha in a fluid motion.
Gloved hands in his curly hair pried him off the alpha’s cock causing him to whine in dismay at the loss.
“Isn’t this poster your most prized possession?” Bakugo taunted, “It’s drenched in slick.”
Fingers tightened in Izuku’s hair, yanking him forward and making him present, causing the dildo to slide out of him, Izuku whined but was quickly sated as Bakugo mounted him, “Fuck, you’re sucking me in sensei.”
Bakugo pressed Izuku’s cheek against the poster, “C’mon, clean it up.”
A pink tongue darted out, licking small stripes of the plastic wherever he could reach, moaning loudly, “Dynamight-sama, you’re so f-fucking big… You’re splitting me in two…”
The alpha smirked, fingers gripping Izuku’s hair, leading him to deepthroat the drenched dildo in time with his thrusts. Katsuki set up an intense pace; slow, deep, torturous… Izuku’s thighs trembled as the alpha’s other hand reached around him, gloved fingers rubbing his clit deftly. Like a rubberband snapping, Izuku’s climax ripped through his body, drenching Katsuki in slick as his pussy clamped down on the alpha’s cock causing his knot to pop immediately, flooding the omega’s insides with cum. Losing all his strength to hold himself up, the dildo slipped out of Izuku’s mouth, springing up at attention as the omega lay boneless in bliss in his nest. His relaxed limbs splayed against his Dynamight blanket, hips held up in place solely by Katsuki’s impressive knot buried deep inside him, still steadily filling him with cum.
“You’re gonna get me pregnant, Kacchan,” he slurred, eyes still closed. The omega smirked as he felt the violent twitch of Katsuki’s cock, clearly interested in that idea.
Bakugo stood outside Izuku’s door, balancing grocery bags in one hand while he entered the security code to enter his lover’s home. Today was his day off and he had planned to spend the afternoon cooking dinner for Izuku. The teacher usually confirmed their plans via text, but all Katsuki’s messages went unread. Entering the apartment, Bakugo felt uneasy; blinds were closed, the air felt strangely stagnant, but the alpha was sure Izuku was here.
“Oi! Nerd!” he called into the dark apartment. He heard something fall, a muttered curse and then quick shuffling toward him.
“Kacchan? What are you doing here?”
“What the fuck happened to you?” Katsuki asked, dropping the bags on the floor, taking in Izuku’s disheveled appearance, “When’s the last time you slept? Or showered?”
“Thursday maybe?” Izuku scratched his head.
“Izuku, it’s Saturday. When was the last time you ate?”
Izuku bristled, averting his eyes as Katsuki picked up the bags to carry them to the kitchen. Izuku blocked him, arms spread wide, “I was busy with lesson planning. Could we reschedule today?”
“No,” Katsuki responded, pushing past him. He flipped the lightswitch on and surveyed the damage.
Notebooks were strewn across the table, the light from his laptop screen barely illuminating the room, crumpled energy drink cans lay on the floor around the overflowing kitchen bin, the sink was piled high with dirty dishes and a layer of dust blanketing every surface.
“Kacchan I’m busy, please,” he whined, face flushed in embarrassment.
“How long will it take you to be finished?”
“A couple hours maybe.”
Katsuki said nothing further, gesturing for Izuku to get back to work. He cleared out a small space on the cluttered countertop to place the groceries and he got started cleaning. He cleaned efficiently, clearing down the countertops, washing the dishes and even cleaning the refrigerator before he packed the groceries away. He made a quick congee, ladling it out carefully into a bowl for Izuku to eat. The teacher accepted gratefully, tired eyes never leaving his screen. Trash was neatly bagged and placed by the door as he vacuumed and mopped, opening the blinds and windows to let air circulate. Izuku hissed at the sudden brightness but quickly refocused on his work. Katsuki picked up stray pieces of clothing, tossing them into the washing machine before entering Izuku’s bedroom. He opened the balcony door for circulation and turned his attention to dismantling and washing Izuku’s nest. After a thorough clean, Katsuki relaxed as he hung up Izuku’s blankets to dry in the sunshine. After taking out the trash, Katsuki decided to tackle the bathroom, scrubbing every surface until they shone. He took a quick shower, changing into some of Izuku’s clothes before setting up Izuku’s nest exactly as it was, carefully scenting each item.
The setting sun cast an orange glow inside the apartment as Izuku finally resurfaced. He blinked in disbelief as he noticed the clean apartment.
“Kacchan, you didn’t have to. I would’ve gotten to it eventually.”
“That’s a lot of words for ‘thank you’.”
“Thank you, Kacchan.”
“Are you finished with your work?”
Izuku nodded.
“Good.”
Izuku squeaked as Katsuki picked him up and carried him to the shower. He reached for Izuku’s clothes, but the omega stopped him, “I can shower by myself.”
The alpha narrowed his eyes, “Fine, but I'm drawing a bath for you after you wash off.”
Izuku conceded, quickly showering before sinking into the bubble bath. He groaned as the hot water soothed his aching muscles. Izuku purred as Katsuki sat on the edge of the tub, fingers deftly washing the omega’s hair.
“Dinner will be ready in a second.”
Izuku hummed in acknowledgement as Katsuki helped him dry off and get dressed in comfortable, Katsuki-scented clothes.
They ate dinner in silence as Izuku’s eyelids felt heavier. Katsuki carried him to his nest, covering him in the soft blankets. Izuku curled up in Katsuki’s arms, the exhaustion finally taking him over as he slipped into slumber.
“I think you should move in,” Katsuki suggested offhandly as he cooked breakfast one morning. Izuku paused, coffee mug frozen inches away from his face, “Sure.”
The movers were efficient, and within one week, Izuku managed to move all his belongings into Katsuki’s house. Their merged hero collection took the longest to set up, deciding to use a small bedroom to house their miscellaneous hero merch and the larger neighboring room as a dedicated All Might display.
Izuku stared at his Dynamight poster, wondering where would be the best place to hang it.
“In our bedroom, of course,” Katsuki suggested easily, “I’ve gotten used to seeing it in your nest…”
Izuku swatted him with the poster, blushing.
“What?” the blond teased, “I thought you love Pro Hero Dynamight.”
“You’re unbearable,” Izuku responded, rolling his eyes. He smiled to himself as he hung it in his nest, secretly pleased that he could keep it near to him.
Katsuki didn’t comment on his poster again, but smirked knowingly when he spotted it. He crowded against Izuku, pressing heated kisses against the omega’s scent gland, “I can’t wait to knot you in every room,” he moaned as Izuku feverishly undressed him.
“We can’t fuck in the All Might room,” Izuku countered breathlessly, “It’s sacred.”
Katsuki nodded solemnly in agreement.
They did. Thrice.
