Okay let’s talk about A/B/O in a universe where Omegas ideal body type are full and fat and curvy bodies.

KRBK, A!Kiri, O!Baku, stuffing, lactation probably

—II—

Kirishima made his way through the grocery store, picking this and that. He had a crumpled list in his hand and a smile on his face.

He had his scent patches on just like all Alphas were required to wear and his muzzle. It wasn’t /required/ but Kirishima was a big guy and he hated looking intimidating.

As he was reaching for a box of cereal on a too shelf he felt something soft brush against his side. He looked down and blushed bright when he realized it was an Omega’s belly.

And not just an Omega, a /male/ Omega. One with blonde hair on his head that matched the blonde hair on the sliver of his fat belly that was showing. Ei looked away, not wanting to be rude as he blushed because /wow/. This Omega was gorgeous.

“Hey, giant red head,” the Omega spoke to him and Eijirou looked down, meeting his pretty red eyes.

“Y-Yes, Omega?” Eijirou deferred, hunching his shoulders to look smaller. He caught a little of the Omega’s caramel scent and he bit his tongue to keep in a moan.

“Get me two of those, will you?” the Omega pointed to the top shelf where he’d been tying to reach and instead had rubbed up against this ripped Alpha.

Eijirou got the boxes down and offered, “Did you need anything else, Omega?”

Bakugou could practically see this Alpha’s tail wagging. He smirked and glanced at his very full shopping cart.

“You think I need more, Alpha?”

“Of course!” Eijirou smiled brightly and Bakugou grinned.

Oh he /liked/ this Alpha.

“Help me with the last few aisles,” Katsuki brushed against Eijirou’s side with his belly as he walked by him, pushing his cart.

“Oh, please let me,” Eijirou placed his own basket of groceries into Katsuki’s cart and placed a hand on the handle, offering to push it.

Katsuki let a smile tug at his lips for a brief moment. Alphas normally didn’t pay him much attention, too deterred by his scowl.

“Alright, fine,” Katsuki let the Alpha push his groceries and he glanced at the basket he had been carrying.

“Don’t tell me you only live off of protein shakes,” Katsuki teased and Eijirou smiled sheepishly. He shrugged, “Yeah mostly... My instincts get kind of uh... triggered by making food for just myself.”

Katsuki hummed in thought a pointed to a few things he needed as they walked, “So you’re not courting anyone...”

Eijirou blushed and shook his head, “I haven’t in a while but I can cook! My Moms always said knowing how to cook for an Omega was really important.”

Snorting at how eager this Alpha was, Katsuki purred softly and reached for something himself, letting his shirt ride up just a little more.

The Alpha twitched where he stood and Katsuki preened a little inside. This handsome, big, Alpha wanted him badly.

“Omega, which way?” the Alpha deferred again and Katsuki purred louder, brushing up against his side. He placed a hand over the Alphas and brushed the scent gland in his wrist over the Alpha’s one covered in a scent patch.

“Call me Bakugou. I’m Katsuki Bakugou.”

The big Alpha shuddered and chuffed nervously, “Thank you, I’m Eijirou Kirishima. You can call me whatever you like.”

Katsuki smirked and squeezed over he scent gland on Eijirou’s wrist, scenting him again before he lead the Alpha around some more.

After they had all and more than what Katsuki had intended to buy, they went to the front and paid. The Omega had to snarl at Eijirou to not buy all of his groceries and baring his little Omega fangs.

Eijirou found it extremely hot that /Katsuki/ let him dote but didn’t demand it. He could already feel his heart aching to leave Katsuki. What if they never saw each other again?

“Why’re you pouting?” Ei had offered to walk Kat to his car and put away his groceries, not realizing he’d been frowning as he did so. Ei blushed and picked up his own bags, “I just... it was nice, getting to know you.”

Katsuki bit back a fond sigh, unsure if this sweet Alpha was /actually/ so kind. Hell he wouldn’t have been surprised if an Alpha demanded to feed and breed him after Katsuki had been so blatantly scenting him. But no, Eijirou was respecting his boundaries.

“Give me your phone,” Katsuki demanded and it was in his hands a moment later. Katsuki entered his number and called himself, so he’d have Eijirou’s number.

“There, don’t go too crazy,” Karsuki said as he handed Eijirou back his phone and the Alpha beamed at him. Fuck that smile was blinding.

“I’ll try not too. Thank you so much, Omega! Oh!” Eijirou dug into his pocket and pulled out his wallet handing a business card to Katsuki.

“I run a gym and spa. We have some really good services, not that you /need/ any of them but,” Eijirou blushed, “I’m usually there if you wanted to stop by and say hello.”

Smirking, Katsuki brushed by Eijirou, soft belly brushing against him again, “I’ll think about it.” He got into his car and winked over his shoulder, “See you later, big boy.”

“Yeah, you too,” Eijirou sighed happily as he watched Katsuki pull out of the parking lot, hearts practically in his eyes.

He sighed again and winced at his words before rushing to his own truck, “I gotta tell T and Mina!”

—II—

Eijirou spent the rest of his day cleaning his place up and texting. Most of his friend squad was working today so Ei found himself opening up Katsuki’s number in his messaging app, a few times, to end up just starting at his curser flashing.

What could he say??

‘Hey I think you’re beautiful!’

‘I’ve already used up all your amazing scent by drooling on my wrist.’

‘The way your belly moves when you walk makes me want to knot my own hand!?’

Eijirou groaned at himself as he huffed and flopped down on his couch, “Why is this is hard!?”

Eijirou heard his phone buzz and he scooped it up, gasping when he realized it was Katsuki that had texted him!!

Katsuki: I could barely fit all that extra shit in my fridge.

Eijirou smiled wide because an Omega texting him first was a big deal. He sat up on his couch and typed back a reply before thinking about it too much.

Eijirou: I could help you fit it in there!

Katsuki laid back on his own couch, hand in a bag of chips Eijirou had suggested he try as he typed. He smiled at the Alpha’s quick reply and typed back his own.

Katsuki: I’d like that.
Katsuki: So do you always keep your hair red?

—II—

Eijirou was so excited. He’d been texting Katsuki for a few weeks now and it was definitely time to start courting him properly.

He rang the doorbell to Katsuki small home, holding a beautifully wrapped package in his hands.

Katsuki answered the door and Eijirou smiled behind his muzzle. The blonde Omega was looking plump and as beautiful as he remembered first seeing him. Maybe a little heavier around his belly, which slight hung out of the shirt he was wearing.

“Omega, most /stunning/ Omega, would you accept my courting?” Eijirou asked, hands shaking just a little with nerves as he held out the gift.

Katsuki gave Eijirou a soft smile, “I will, handsome Alpha.” He took the gift and held his door open.

“Come in while I open it and we can plan for our next courting,” Katsuki offered and Eijirou rumbled out a purr as he walked inside.

Katsuki rubbed up against Eijirou and the Alpha slid their wrists together breathing in deep, “You smell so good.”

Purring his approval, Katsuki closed the door and walked to his kitchen counter, “Take off that muzzle.”

“You sure?” Eijirou asked softly and sat when Katsuki pointed with a box cutter to one of his bar stools.

“Kirishima, /I know/ you’re a smart guy - smarter than people think - and /you know/ I don’t like to repeat myself,” Katsuki picked up his scissors and cut the overly large bow off of his gift, “I also don’t say things I don’t mean.”

Katsuki gave him a stern look and Ei took off his muzzle, sitting it on the counter. He smiled sheepishly and Katsuki nodded, “You have a great smile.”

Eijirou blushed and purred happily, though his scent was still concealed with patches, “Thank you, Bakugou.”

Katsuki purred his approval and continued opening his courting gift. His nose twitched just a little as a musky, rich scent hit him. It smelled like warm cinnamon and cloves.

He pulled out a deep maroon hoodie. It smelled /good/ like happy, protective, pleased Alpha. Katsuki wasn’t shy as he lifted it up to his face and inhaled deeply, unaware of Eijirou’s eyes on him.

Katsuki purred loudly and rubbed the fabric against his neck, claws coming out briefly to knead the fabric. He sighed and pulled the hoodie over his head.

“It’s almost perfect, it’s just kind of big for me,” Katsuki noted, pulling the part around his belly out a little to show how baggy it was.

Eijirou bit he lip, “I thought... you could grow into it.”

“Oh,” Katsuki blushed and walked around the counter to stand in front of Eijirou. Because Ei was sitting, it left them more at eye level and Katsuki moved to stand in between Ei’s thighs.

“I accept your courting,” Katsuki placed a hand on either of Eijirou’s big shoulders, looking up at him with lidded eyes.

Eijirou’s heart was hammering in his chest. He’d liked other Omegas and Betas before but something about Katsuki just excited him.

Placing a hand on Katsuki’s hip and the other on his lower back, Eijirou smiled his big megawatt smile.

“Thank you, Omega, /Katsuki/. I promise to be good to you,” Eijirou blushed and leaned in.

“I know you will be,” Katsuki brushed their lips together. He intended to pull away - to tease- but Eijirou caught his lips again and held him close, kissing him so good and sweet and perfect that Katsuki melted a little.

Eijirou pulled back, face flushed and smiled, “Sorry I just- you’re so gorgeous.”

Katsuki blushed but smirked and moved to tug at Eijirou’s hair, “you’re not so bad yourself, Alpha.”

Ei puffed up a little and Katsuki snorted, hands moving to pat Eijirou’s chest, “Calm down, big boy. No need to posture for just me.”

Eijirou sputtered and Katsuki laughed, moving out of his hands.

“Dumb Alpha,” Katsuki smiled, “so you said you wanted to cook for me next week?” The blonde scented Eijirou’s wrists again before pulling him out of the chair to sit on his plush sofa with him.

They talked and kissed a little more, making plans to see each other next weekend. Katsuki walked Eijirou to the door and they kissed one - two - three more times before parting ways.

“Goodnight, Katsuki.”

“Goodnight, Eijirou.”

Top of the thread! https://twitter.com/HimbosOnly/status/1316458798001856512

—II—

Eijirou and Katsuki texted each other all the time. Ei would send pictures of flowers from the shop next to his gym, asking which kind Katsuki liked better. While Kat would send him pictures of the blueprints he wad working on from home.

Eijirou found Katsuki’s work so interesting. He was an architectural engineer and helped the city build not only office buildings but statues and monuments. Ei loved to listen to Kat talk about his work. He was so smart!

Eijirou fired off a selfie of himself at the gym, smiling wide at the camera. Katsuki popped back quickly.

My Katsuki : How about one without the top on? ;)

Eijirou grinned and lifted his tank top up, holding it in his teeth as he took the picture. His hard chest and abs on full display for his soft Omega.

Eijirou : How’s that?

Katsuki was in his nesting room, enjoying the low lights and warm blankets. He was wearing Eijirou’s courting present because he /always/ wore it and purred loudly at his phone when Ei’s picture came in.

My Katsuki : Perfect. You look so sexy, Alpha. I’m sure I’ll appreciate this picture for my heat.

Eijirou : Augh! Yes, thank you! But now I gotta think about bad things so I won’t have a semi while I work out!

My Katsuki : Be safe, Alpha.

Eijirou : You’re so mean!!!

Eijirou : I’ll call you later!

My Katsuki : Sounds good.

Katsuki finished up his day at work and curled into his nest. He had a nice big dinner and a cup of tea. The full moon was still three days out but Katsuki could feel it. This heat was going to be rough with him now courting an Alpha.

Now that his Omega knew he had a willing Alpha it would demand Eijirou be with him. But Katsuki wasn’t ready for that by any means. They were only about to go on their third date. So he would just see Eijirou as close to his heat as he felt comfortable and maybe...

See if Eijirou would give him a pillow or something.

Katsuki purred and kneaded his blankets and hoodie, yawning. His eyes opened when he heard his phone ringing and he answered with his usual rough, “Yeah?”

“Hey Katsuki! How was your day?” Eijirou’s cheery voice said and Katsuki smiled to himself, holding his phone close enough to nuzzle. He wanted to scent Eijirou, wanted to make sure the Alpha always smelled like him.

“It was good, got that project outline approved,” Katsuki hummed.

“That’s awesome! I know you were working so hard on that,” Eijirou sounded out of breath and Katsuki knew he was running home.

“Yeah, been two months of edits,” Katsuki smiled, thinking about Ei running and looking like a fucking model Alpha with his big smile, “How was your day, Ei?”

Eijirou rumbled happily at the nickname, “Good! Got all the things I need for tomorrow night! You like things extra spicy, yeah?”

“Mhmm,” Katsuki purred and stretched in bed, looking down at the way his shirt rode up on his belly.

He’d noticed most of his clothes fitting a little tighter and it seemed after a month of an interested Alpha he’d started packing on more weight.

Omegas being overweight wad only ever seen as a good thing. Wide hips for birthing, fat for tough times when Alphas couldn’t find food and Omegas bodies suddenly became the only nutrient resource in the form of milk.

While it was a modern era now, those truths still held up for both Omegas and Alphas. Katsuki slid a hand down to pet over his heavier belly and sighed into the phone. Eijirou spoke up, “Did you like my picture?”

“Yeah... you looked so good,” Katsuki breathed out as he reached down to cup his little cock through his shorts.

Eijirou blushed and rumbled back to Kat over his airpods, glad he had his muzzle on because he was running by some people.

Katsuki chirped out a pleased sounds and purred into the phone, “You want a picture of me?”

“Katsuki- You know I do-“

“If you tell me it’s inappropriate one more fucking time, I’m never sucking you off.”

Ei’s complaint about being sent a picture died right then and there. It was dumb anyway. Eijirou saw it as a courting gift and /Alphas/ gave the gifts. They had been bickering about it but Katsuki knew he’d break if given the right incentive.

“You play dirty, my dearest,” Eijirou bemoaned into his phone and Katsuki barked out a laugh.

“You say that as if you aren’t the one getting the goodies,” Katsuki snorted.

The blonde laid back in his nest and tugged up the hoodie Ei had gifted him, letting his chubby little pecs out. He pinched and plucked his nipples just to make them swell a little before he sent to picture of his full belly with his chest from an upward angle between his legs.

“You’re almost home now, right? Don’t look at your phone until you’re inside,” Katsuki spoke huskily and Eijirou shivered from head to toe.

Eijirou was /coated/ in sweat by the time he got home and he rushed to his bathroom, turning on his shower and immediately looking at his phone.

“Oh fuck... fucking look at you,” Eijirou panted, he sat his phone on the bathroom counter and started pulling off his clothes.

“You like it?” Katsuki asked and Eijirou moaned, briefly forgetting he was on the phone with his Omega. Ei unsnapped his muzzle and placed it on the counter, “Hell yeah, did you just take that?”

“Yeah,” Katsuki purred, burrowing into his nest as he pushed down his shorts.

“You look... so sexy and so soft, Omega,” Eijirou panted as he growled softly between his words.

“Baby, you gotta either hang up or listen to me beat the hell out of my dick. Fuck your lips are so plush and sweet looking,” Eijirou moaned and clenched his free fists against his counter as his very hard cock throbbed against his belly.

My Katsuki wants to FaceTime!

Eijirou gasped and whined softly, Katsuki was gunna kill him. His hand shook as his answered, “Hello?”

“Eijirou,” Katsuki purred and chuffed a little, face pressing against his phone, “Alpha.”

Eijirou groaned and turned his camera to face him, smiling sheepishly, “Don’t hate me for this.”

He left his camera facing up at his ceiling as he stepped into the shower. Eijirou stroked his cock from base to tip, fingers squeezing his tip and his knot until he moaned.

“Nn I wanna see you!” Katsuki snarled and Eijirou twitched towards his phone wanted to comply. It wasn’t a Command but Ei was a very submissive Alpha. He whimpered and shook his head.

“No, I wanna see you and you see me first in person. I wanna see your pretty eyes,” Eijirou spoke back, leaning against the cool shower wall to bring himself some clarity.

“Fuck you. Fuck your romantic ass,” Katsuki growled again and Ei choked on a sound when he could hear Katsuki fingering himself.

“You’re that wet outside of your heat?” Ei asked breathlessly the sounds of his shower and him stroking his cock echoed in the background.

“You won’t let me /look/ at you and then you’re gunna say shit like that. You know what!? Unfuck you, stupid knothead,” Katsuki huffed, his normally pale face absolutely red.

Eijirou grinned and glanced at his phone through his clear shower curtain, “Well?”

Katsuki huffed loudly again and then gasped, moaning softly, “Mm maybe, I’ll be wetter now that I have a proper cock in me.”

Eijirou shivered at he image. Katsuki had a massive dildo that he loved called ‘King’ and Ei had the pleasure of meeting him two night ago.

Ei knew a tease when he saw one. Katsuki had left the dildo in his bathroom, /knowing/ he’d see it. As much as his Alpha howled at him to show his Omega he was bigger, Ei also just liked to tease Kat about leaving his things out. Dirty boy.

Eijirou did let himself growl, words garbled around his sounds, “If you think that’s a proper cock then you’ll be aching when I knot you, pretty.”

Katsuki gulped and stifled his whimper as he pushed his toy in and out of himself slowly. King was a tapered dildo, more than Ei’s cock would be and Katsuki couldn’t /wait/ to feel how wide his Alpha would eventually stretch him.

And that /nickname/. How fucking dare he!? Katsuki chuffed and purred, nosing his phone, “I want that. I don’t want to be able to walk the next day without feeling you inside me.”

Eijirou moaned and stroked himself face, panting softly as the image of Katsuki knotted and full of his cum. How big would his beautiful Omega get?

“I can do that,” Eijirou growled and chuffed, squeezing his knot. He pumped his cock, listening to Katsuki’s sweet sounds.

The Omega mewled and pushed his toy in deep, gasping, “Alpha! Knot! Knot me!”

Eijirou gasped and tears prickled in his eyes as his knot filled quickly in his hand, “Omega!” He cried out, squeezing his knot and cumming hard onto the opposite shower wall.

Katsuki keened and dug his claws into his hoodie, accidentally tearing the front pocket as he came. His small cock throbbed and he purred as his hole fluttered, trying to milk a knot.

Eijirou sighed and let the shower water spill over him as he watched the biggest load of cum he’d ever spilt wash down the drain.

“You cum, Katsuki?” Eijirou asked and Katsuki mewled back. The redhead could only laugh.

—II—

The next night was their dinner date and Katsuki pulled on his hoodie and a pair of ripped black jeans. While the rip in the hoodie kinda matched the aesthetic he was going for... he still hated that he’d hurt Ei’s gift.

Katsuki painted his nails black, applied his eyeliner sharp enough to pierce the hearts of his enemies, and slipped some comfortable shoes. He looked at his heels and clicked his tongue - those were for another time.

He held off on the lipstick because they were having dinner after all and checked his hair in the mirror one more time before catching the train to Eijirou’s place.

My Katsuki : Ei, you don’t have to go insane with this dinner.

My Katsuki : I did remember the scent patches if my preheat scent is too much.

My Katsuki : You better not be freaking out.

Oh fuck, Eijirou freaked out, Katsuki was going to be here any minute!!!

He looked at his phone just as his door bell rang and his Moms squealed their excitement for him.

“Gotta go! I love you both!”Ei grinned and his Moms gave him thumbs up as he clicked the end call button.

Warnings: Stuffing, Feeding, Weight Gain

Hey y’all, I know I mentioned that these kinks are a part of this thread but after talking to some folks I thought I’d tag these scenes before and after just in case. No shame if it’s not your cup of tea.

—II—

"Hey, stud," Katsuki smiled just a little as Eijirou opened the door and he purred as he walked in. It smelled /amazing/. He'd never been in Eijirou's home and the smell of his Alpha along with what had to be a delicious dinner had Katsuki's Omega preening.

"Hi," Eijirou blushed at that nickname but grinned and purred when Katsuki brushed by him, scenting their wrists together. Ei leaned down and kissed him, brushing their cheeks and necks together, "You look amazing."

Ei spoke in that awed voice, as if he'd never seen anyone wear eyeliner and Katsuki loved it. His sweet Alpha was always so impressed even with the little things and Ei never hesitated to shower him in affection on genuine any kind of self consciousness he felt was destroyed.

"Thanks," Katsuki kissed Ei again before the Alpha took off his large black coat over his hoodie. It was getting cold out and Katsuki was /always/ freezing. He looked Eijirou over and oh fuck he was so cute.

He was wearing a deep burgundy button up, with the sleeves rolled up to his elbows, showing off his big arms. It had a few stains on it - clearly from cooking. His black pants had finger smudges of flour and his hair was up in a sloppy bun. Katsuki could not have loved him more.

"Handsome Alpha," Katsuki purred against Ei's lips and kissed him again. His scent was strong and Ei breathed him in deep before he was stepping back with a blush. He led Katsuki into his house and walked him through it.

Ei had just pointed to his bedroom and Katsuki took in a sharp breath that they both pointedly ignored as Katsuki's scent deepened with a spice of arousal. It would have been worse if Eijirou was in his nest, that... that would have been hard to resist.

Katsuki followed Eijirou into his dining room/kitchen and purred when Ei pulled out a chair for him to sit. It was just a small four seat, wooden table but their were two placemats set out and their plates were placed out neatly.

A red candle was lit in the center and there were orange lillies on the table that Katsuki liked, "Ei you really didn't have to-"

"Katsu," Ei leaned down to kiss his cheek, "I'm the one courting you. I want you to always have the best I can offer."

Kat blushed and Ei grinned. The blonde huffed and his belly growled loudly. Eijirou purred and kissed his cheek and down to his neck, hands moving to rub Kat's shoulders just briefly, as he murmured in his ear, "Besides your heat is tonight, I wanna make sure you're well fed."

Katsuki blushed to the tips of his ears and purred louder, turning to kiss Eijirou. He bit at Ei's lip and sighed, "I wish you'd spend my heat with me."

Ei inhaled sharply, caught off guard by his Omega's forward nature. Though he should have expected it with Katsuki.

"Once we're done courting... when you have a chance to really think it over," Eijirou kissed him again, "I will."

Katsuki sighed and nodded, watching Ei leave to get their food from the kitchen. They really had only been dating for a little while.

Some couples mated quickly and Katsuki didn't shame anyone for their choices but he and Ei were both the type to want their mating to be for the long haul. Did he want to always be by Ei's side? To grow with him and be with not only who Ei was now but who he was in 40 years?

Katsuki toyed with where he'd torn the hoodie. Would Ei want who he was everyday? Even on the bad days? Those cruel thoughts made his heart ache but it was immediately washed away as Eijirou walked over with a plate of pot stickers, his big smile on his face.

"Did you make those youself?" Katsuki asked, lifting up his chopsticks when Ei placed the whole plate in front of him.

"Yep, my Mama's recipe! Oh and here's the sauce," Ei placed a little dish of sauce that clearly had chili oil on top and Katsuki purred, grinning when Ei place the chili oil bottle on the table for him.

"Fuck yes. How are your Moms, Ei?" Katsuki asked before picked up the hot potsticker and dipping it into the sauce, there were little diced green onion in it too. The blonde popped his tasty morsel into his mouth and groaned at the flavor. /Goddamn/, Ei could /cook./

Eijirou stirred the pot on the stove, trying - and failing - to be subtle as he glanced over at Katsuki eating. His Alpha purred in pride at seeing his Omega eating happily. The sight and scent of Katsuki so content before his heat made Ei glad he’d worn compression briefs.

“They’re good. Mama is working on her gift for you and I told her your favorite colors. Ma has /already/ bought us tickets to come see them,” Ei smiled sheepishly, embarrassed just a little at his over eager parents.

Katuski kept eating as he listened and he smiled fondly, “They’re so sweet. Maybe next month we can go meet them? I’d like you to meet my parents sometime too,” the blonde hummed and spoke between bites.

“That’d be great! Ma had been wanting to book an Onsen trip, get up there and see the snow,” Eijirou noticed Katsuki had finished the dozen potstickers he’d given him and he placed some more in front of him, having kept the extras warm on the back burner.

“Did you want any of these, Alpha?” Katsuki asked, looking up from under his lashes just to hear Ei groan.

“I saved some for me. I’m almost done cooking, pretty,” Ei kissed Katsuki and purred lowly, “You eat as much as you want.”

Katsuki licked his lips and looked Eijirou over as the big Alpha put rice on plates for them. He poured a plate of his Mama’s spicy beef stew over the rice for them both, making sure Katsuki’s portion was larger.

“Your parent work in the clothing industry right?” Eijirou asked as he placed the plate beside the one with the potstickers.

Nodding as he swallowed, Katsuki spoke as Ei refilled his glass of water, “Yeah they’re both designers.”

“Guess they’re lucky to have a son that looks like a model,” Katsuki snorted and started laughing. Ei chuffed, huffing a little, “I mean it.” The Alpha had a blush on his face as Katsuki sighed, “Yeah... I guess... I just used to be thinner.”

“Katsuki, your /weight/ is only a positive thing,” Eijirou said firmly in a voice Katsuki had never heard him use. He sounded so determined. The red head looked over and Katsuki’s breath was taken at the fire in his Alpha’s eyes.

“Anyone who would shame you for your size is a fool and doesn’t see that you are a /perfect/ Omega,” Eijirou’s eyes softened, “Who wouldn’t want more of you?”

Katsuki blushed and stuffed another bite into his mouth and moved to rub a socked foot against Ei’s calf under the table, “Flatterer”

“More like stupidly honest,” Eijirou grinned and ate a bite of his own food.

Katsuki continued eating with a smile tugging at his lips. God when had he ever been so open with anyone? Eijirou just made him feel so safe.

“So my parents next month and then yours maybe the weekend after?” Eijirou smiled, glad that his Omega was back to eating, “I wouldn’t want them to think I’m avoiding them.”

Katsuki snorted and rolled his eyes at the thought of his Mother. She would probably chew them both out either way.

“Yeah that sounds good, Ei.”

They continued eating and talking, making plans to hang out with each other their friend groups, their next date, and how each of their jobs were going.

Katsuki knew how to make Ei laugh so hard and Ei always supported Katsuki in all of his endeavors. After Katsuki had put down two plates of Ei’s stew and lost count of those potstickers, he sighed and placed a hand on his full belly, “Ei that was so good.”

“You have room for dessert?” Ei said as they both stood at the sink, washing the dishes. Katsuki was practically tucked against Ei’s side, drying and smelling so caramelly sweet.

Katsuki looked up at Ei and licked his lips, “I could maybe make room...” The blonde Omega smirked up at his Alpha when Ei purred in approval.

They finished up the dishes and moved to Ei’s living room. Katsuki got comfortable on the couch, taking off his hoodie and revealing a too tight black shirt underneath. Well it hadn’t been too tight when he’d left home.

Now Katsuki full, soft belly hung out of his shirt just a little. His soft pecs clearly outlined as well as his belly button. Before he could be too shy about his looks, Katsuki pulled the red blanket off of the back of the couch to snuggle up in.

Eijirou could see the couch from his open kitchen and as he pulled out the berry trifle he’d made, he saw how much bigger Katsuki had gotten. His Alpha preened as satisfaction curled in Ei’s belly.

His Omega was beautiful, loved, fed, and felt so content that he was gaining weight as if to settle into a nest with pups. Ei bit his tongue hard to keep his cock from stiffening at the idea of Katsuki heavy with pups.

Ei quickly thought of other things; Dead things, chaos, that one smelly gym bag, okay okay. He would be fine.

“Can we make popcorn after dessert, Ei babe?”

Eijirou bit back a whimper. He walked over to the couch and sat down beside Katsuki putting a big arm around him, “Of course we can!”

Ei put some of the trifle into a bowl. There was pound cake with a mixed berry compote poured over it and then layered with cool whip and some vanilla wafers for texture.

Katsuki watched as Ei poured a little extra honey onto the bowl. He combed through Netflix and settled on the anime they’d started watching together.

Holding his hands out for the bowl, Katsuki raised an eyebrow when Ei held it with a blush, “Would you mind,” Ei bit his lip, “If I fed you?”

Katsuki’s eyes widened and he tapped a black nail on the TV remote thoughtfully, “You’re not going to be able to read the subtitles if you’re focused on me...”

“Baby, I’m always focused on you,” Ei grinned and Katsuki snorted, smacking him on the thigh.

“Alright, just go slow, I am already pretty full,” Katsuki put a hand on his belly and Ei purred loudly, making his Omega shake his head. Dumb Precious Alpha.

Katsuki played the show and blushed when Eijirou held up a spoonful of the dessert to his mouth. He ate it timidly but purred at the flavor. It was sweet and creamy but light and crunchy and Katsuki slid a hand down to rest on Ei's thigh, nails digging into his pants.

The feeling of being fed and taken care of so thoroughly by the Alpha courting him had Katsuki's breathing picking up and his heart raced just a little. His pre-heat was in full swing and he knew he'd have to leave Ei in a few hours.

Katsuki wanted to pout about it. He wanted to huff and whine and pull Eijirou into his nest but no. No, he also wanted to wait. The blonde opened his mouth for another bite and Eijirou chuffed in happiness.

"How's it taste, pretty?" Eijirou chuffed again and Katsuki let a smile curl his lips.

"Good. It's really good, Ei," Katsuki tilted his chin up and instead of another bite, Eijirou pressed his lips to Katsuki's own. He licked into his Omega's mouth, groaning softly.

They parted and Ei offered Katsuki another spoonful, placing the bowl in his lap and hesitantly reaching for Katsuki's soft belly.

"Can I touch you?"

Katsuki keened between his bites and heat flooded his face. He huffed at his own eagerness and nodded curtly, "That was a yes, if my dumb Omega wasn't clear."

Eijirou shivered at that keen and gently put a hand on Katsuki. He was warm and soft but his little pudge was already getting tight, Ei sighed longingly, wanting to fill Katsuki so full.

They'd get there, Ei wanted to take things slow. He wouldn't be an Alpha that just fattened up his Omega quickly with cum and left them to fend for themselves.

No, Eijirou wanted Katsuki to be heavy /always/. He wanted his Omega to enter a room and draw all eyes with his size. He wanted any Alpha to glance at Katsuki and feel weak in the knees at how gorgeously plump he was.

'He must be a breeder Omega,' They'd think as Katsuki walked by and Eijirou would be right there to say no. My Omega is just well taken care of. I've fed and loved him so much he's gotten huge. He could carry a dozen pups and last through the longest winter.

The thought of Katsuki being so big and content and happy, always made Eijirou shiver in excitement. He didn't realize that he'd stopped feeding Katsuki and gone still, mouth hanging out and eyes bright Alpha red.

"Eijirou? Earth to knot head!"

"Hmm, yes Omega?" Eijirou smiled dopily and Katsuki reached a hand up to cover his laugh.

"You're pheromone drunk, aren't you?" Katsuki could see it. Ei's eyes were dilated, glowing red just a little. Plus that scent. Katsuki had never smelt anyone so content.

"'m not," Eijirou huffed and shook his head, trying to clear his head. His purring was loud and Katsuki just smelled so good. Like caramels and salty ocean breeze. He was scenting all over Ei's apartment and he wanted to roll in it.

"Eijirou. You're drooling," Katsuki huffed out a laugh and tsked. He leaned over a little and fished around in his pocket for his wallet. He pulled out two scent patches and opened them in his lap, ignoring the way Ei whined.

"You're lucky you're cute."

Katsuki peeled the patch off of it’s paper and placed it onto the scent gland on the side of his neck.

Eijirou whimpered but blinked his eyes, even just that bit of coverage was enough to help him come out of his haze.

Ei blushed as Katsuki placed the second patch onto the other side of his neck. The hand he still had on Katsuki’s belly faltered. How dare he give in to his instincts like that!? Eijirou started to pull his hand away but Katsuki stopped him.

“I’m still hungry, my doting Alpha,” Katsuki looked up at Eijirou fondly and the Alpha smiled sheepishly. He fed Katsuki another bite, making him purr as Ei rubbed his belly, “Feels good, Ei.”

Chuffing at the praise, Eijirou watched Katsuki licking his lips between bites or when some got on the corner of his mouth. His belly was slowly getting tighter and tighter as the Omega ate the entire dessert.

Katsuki whimpered around the last few bites, hands laying over Ei’s on his belly, “I’m so full. Nngh.”

“Yes you are...” Ei sighed happily and put the plate and spoon down so he could put both of his big hands on Katsuki’s swollen tummy.

“Beautiful,” Eijirou said under his breath as he looked Katsuki over. His black shirt had ridden up even more, now just a little of his belly button was peaking out. Ei ran his fingers over the hair on Katsuki’s belly and purred.

Katsuki was panting as Ei touched his belly. He whimpered and whines when his Alpha pressed too much and mewled when Ei bounced his belly.

“Fuck! Nngh fuck,” Katsuki blushed and panted softly.

“Is it too much?” Eijirou asked a little nervously and Katsuki shook his head no.

“No it’s just... with the pre heat... feels good... probably too good,” Katsuki sighed and leaned back into the couch.

Eijirou loved hearing that. He preened a little and nearly jumped out of his skin when an alarm on Katsuki’s phone blared.

“Fuck... Only an hour left before Moonrise. I gotta go Ei,” Katsuki sighed.

They were both quiet for a moment, the longing to say /stay/ was on both of their tongues.

“Okay,” Ei said in a tone so soft and sad, Katsuki opened his mouth but snapped it shut before he asked.

“Dinner- Tonight was perfect,” Katsuki said instead and he leaned up with just a little struggle to kiss Ei sweetly.

“Yeah?” Ei smiled sheepishly and Katsuki’s heart ached with affection.

“Yeah, babe,” Katsuki brushed their wrists together and shivered at the bliss of scenting his Alpha so close to his heat.

“Take me to my nest, Ei,” Katsuki purred and Eijirou chuffed, standing and leaving their dishes to take Katsuki’s hand. He helped him up and briefly admired how his belly hung before watching him slip on his hoodie.

Ei opened his fridge and pulled out a few containers of packed food, placing it in a box. Katsuki raised an eyebrow and Ei blushed, “I didn’t want you to get hungry...”

End of the stuffing/feeding scene!! Though I may reference it

Look out for more warnings because there will be more of those scenes

—II—

Eijirou and Katsuki got into the Alpha truck and he drove his Omega home so no Alpha would catch his scent on the train. Even with his biggest scent glands covered, all Omegas were vulnerable on the night of the full moon.

Taking the box with them, they kissed goodbye at Katsuki’s door.

Soft lips met slightly chapped ones and the longing in both of their eyes was intense. Eijirou eventually sighed and stepped back, handing Katsuki the box.

“I-“ Ei hesitated but kissed his Omega again, “Open the box before you settle into your nest, pretty.”

Katsuki’s eyes were dilated and Ei could smell the longing from his beautiful Omega.

“Alright... drive safe, Alpha,” Katsuki sighed and kissed Ei one more time. He was trembling as he opened his door and carried in the large box. His Alpha was /leaving him./

No, no... His Alpha was doing exactly as he was told. He was an obedient and strong Alpha. He would be a good mate, take care of all of his needs.

Katsuki sat the box in his kitchen and opened it up. He gasped when he noticed something beside the food.

Inside the box there was a huge stuffed squishy pillow in the shape of a little demon. It was red like Ei’s hair, had two little fangs like Ei’s teeth, and it was /so/ soft. He picked it up and squeezed it in his arms, breathing in and Ei had even scented him.

Katsuki picked up the note Eijirou had left on how to heat up the food and that apparently this plushie wad named Dante.

The Moon would be up in about 7 minutes, Katsuki didn’t need a clock to know.

So he sat Dante in one of his kitchen bar stools and quickly put away the food. He picked up his new plushie son and headed into his nesting room.

His heat would be starting soon.

Moonrise hit Katsuki like a ton of bricks. He stayed curled up in his nest for the majority of his heat, only getting up for some snacks and water. He thought of Ei as he came on his toys. They’d have many heats together eventually.

Most of the night, Eijirou was restless. He rutted into his fleshlight for hours, imagining it being Katsuki’s warm, wet hole was so fucking good. He pressed the blanket Katsuki had been wrapped in to his face all night, huffing that delicious scent.

In the morning, Katsuki was heating up some breakfast and a knock on his door caught his attention. He opened the door and a Beta smiled at him wearing an Uber eats hat. The driver offered him a coffee and he took it with a raised eyebrow.

Eijirou’s face popped up on his phone a few minutes later and Katsuki smiled, answering and snorting at how tired Ei sounded.

Katsuki was an early riser and very predictable where as Ei set his own hours and liked to sleep in.

After making sure Katsuki had his coffee and was content after his heat, Eijirou fell asleep on the phone. Katsuki may have left it open so he could hear him snore.
