“Your boyfriend is so hot, Kats.”
Denki sighed, stretching as he got ready for his daily attempt of yoga. Katsuki stared at him and shrugged. He was used to people saying that. They weren’t wrong either. Midoriya Izuku was hot and the best thing that ever happened to him. He was truly lucky that Izuku saw him best his exterior and loved him for him.
Katsuki watched his roommate stretch in the shortest shorts known to man. He always wondered how that was supposed to be comfortable to workout in when he would’ve been worried about his ass cheeks popping out. A ring at the doorbell reminded him that his boyfriend was supposed to stop by. He quickly ran to the door, ignoring the giddiness he was feeling as he swung the door open.
Izuku greeted him with a smile, holding a box of pizza. He quickly gave his boyfriend as kiss on the lips and walked inside, placing the pizza on the dining table. Katsuki opened the pizza box and grinned at the fact Izuku remembered Denki hated pepperoni. He turned to face Izuku to thank him only see him staring at the ass that was right in front of him.
Denki’s ass was up high in the air as he whined about being stiff from having stopped for over a month. His shorts had indeed ridden up and his ass was sticking out. Katsuki should’ve been angry at Izuku for staring but he couldn’t stop staring himself. He has seen Denki naked before but this felt different.
He wasn’t sure why.
He believed that his inner self missed fucking some ass.
Izuku was strictly top and Katsuki didn’t mind, he was a switch.
But now, seeing such a plump ass in front of him, he so desperately wanted to fuck him.
Katsuki glanced back at Izuku to see the man staring at him with a look oh so telling. He knew what Katsuki was thinking. It was if he could easily read his mind from a simple look. Izuku walked over to Denki and teasingly tapped his ass. Denki gasped and tore off his headphones as he turned around to face the couple.
“Hi, Izuku! I didn’t hear you come in!” Denki giggled, as if he didn’t almost send the two men into a rut for some fucking. Being alphas and Denki being an omega with the sweetest smell of sunflowers was sickening.
“Your shorts have ridden up, Denki.” Izuku said, hiding any lust behind his usual kind smiles.
Denki laughed, “yeah, sorry about that! My ass was probably nasty to see.”
Quite the contrary, Katsuki almost replied.
“Pizza? You staying over tonight for a movie?” Denki grinned, getting up as he subtly fixed his shorts. “Let me go take a shower and then we can get started!” He quickly ran to the bathroom.
Izuku smirked. “You’re lucky he didn’t see your boner.”
Katsuki blushed. He glanced down to see he indeed was hard.
“Sorry. I know how possessive you are. Especially since you can’t really mark me.” Katsuki muttered as Izuku walked over to him, having only a few inches on the other alpha. Izuku hummed as he pressed a soft kiss on Katsuki’s spiky blonde hair, reaching down to gently kneed his plump ass.
“It’s fine. I like Denki. He’s cute.” Izuku whispered. “You are an alpha and I’m sure you miss actually using your cock.” He grasped Katsuki’s boner through his gym shorts, smirking at the hiss that came from his mate. Despite not being able to properly mark him—their alphas saw each other as mates. It was something rare that they were sure was just something only they could possibly achieve.
Katsuki sighed. “I don’t want to do anything that could ruin our relationship. Even with Denki, I don’t want to scare him away.”
“I understand. I want our relationships to stay the same too. But not with Denki.”
Katsuki raised an eyebrow at that, “what do you mean?”
“I wanna make him ours. You fuck him first and then I fuck him.” Izuku grinned, reaching inside Katsuki’s shorts to grasp his aching cock. “No boxers? Good. An omega can always have more than one alpha as long as those alphas are in love with each other.”
Katsuki sighed, gripping at Izuku’s shirt as he shallowing thrusted into the warm hand grasping his cock. “Yeah, you sure you’ll be able to share? You never seemed like the type, Alpha.” He teased, nipping at Izuku’s scent gland to help it flood the room. Izuku did the same, wanting the room to get drowned in their scent if they wanted Denki to quickly be in the mood like they were.
“It’s not like he’s only having you. I’ll have an equal part of him,” Izuku sighed, grunting at Katsuki’s wondering hands that rubbed his crotch through his jeans. It continued on like that, the two groping each other as they desperately wished they could just fuck in the living room right now. But they both knew that if they fucked—they wouldn’t allow Denki to join in.
To do this right, Denki would have to be the main focus for the night.
“Ugh, guys! Don’t stink up the living room!” Denki whined, causing the two alphas to blush and quickly pull away. They hadn’t even notice that the shower turned off. Denki was wearing a loose shirt that belonged to Katsuki and biker shorts that were almost impossible to see if he hadn’t leaned over to open the windows. Izuku couldn’t help the growl that left his lips at the thought of his omega not liking his and his mate’s scent.
Denki stared at him in shock, “Izuku, I didn’t mean your scent smells! It’s just a lot, y’know?” He glanced over at Katsuki for some help but only received a glare. Katsuki was also a bit pissed himself about his future mate not liking his scent.
“It’s a lot for an omega, guys! My nose is sensitive.” Denki muttered before forcing a smile. “Ah, anyway! Let’s eat! Hope the pizza isn’t cold!” He quickly ran to the kitchen to grab plates while Katsuki turned his attention over to Izuku.
“I’ll close the windows. You get him ready.” Izuku whispered as he walked over to the windows. Katsuki grabbed the television remote and quickly put on a random romance movie to make it seem like he was acting like usual before joining Denki in the kitchen.
Denki smiled as he handed him a glass. The omega continued to grab two other glasses but before he could turn around, Katsuki caged him in against the countertop. Denki flinched as he placed the cups down and shivered at the feeling of hands on his waist.
“Kats! What are you doing?”
“What do you think, Denki?” Katsuki smirked, pressing a soft kiss on his scent gland.
Denki cried out, his entire body trembling. Katsuki stared at him in shock. He forgot how sensitive omegas could be to a highly compatible alpha. Katsuki continued with his little game, nipping at Denki’s scent gland to get his scent flowing as it began to mix and swirl with his own and Izuku’s.
“Katsuki! You have Izuku! Please, stop—”
“—stop what?”
Denki paled at who had spoken when Izuku stared at the two. The omega expected the alpha to lose his shit and attack him, yelling about how much of a slut the unmated omega was. He had that happen before and was ready for it but was only met with confusion as Izuku only walked over to them and kissed Katsuki on the lips before turning his attention to the omega who blinked owlishly at him.
“Izuku—”
Denki moaned at the alpha kissing him on the lips. It was soft and slow. Denki could feel Katsuki’s hands groping his body while Izuku simply caressed his face. The feeling of being touched all over was something different—especially to a virgin omega. Soft moans left the omega’s lips as he felt Katsuki’s fingers trace his crotch area. Male omega’s had small cocks that could honestly be referred to as a clit at best. It was hardly two inches that was inferior to an alphas six to eight inches cock.
Katsuki grasped Denki’s biker shorts and easily tore it, causing Denki to gasp at the amount of strength the alpha had. Izuku took this as a chance to shove his tongue in Denki’s mouth, tangling their tongues together. Denki swore that Izuku must’ve had a tongue that was longer than the average human at how deep it went inside his mouth. Their tongues tangled as one as salvia dripped from their mouth—earning a ‘ew’ from Katsuki.
He hated kisses like that but it seemed Denki was into it at the amount of slick leaving his pink asshole that gushed it out like a faucet.
“Thank you for the food!”
Denki tightly grasped the edge of the countertop as he screamed into Izuku’s mouth at the feeling of a tongue at his puckered hole. The hole lapped at his fountain of slick before thrusting inside with ease. Denki’s thin legs shook as he could feel himself overheat. How did it get here so fast? How long did Katsuki and Izuku plan to fuck him like this?
Izuku pulled away from the kiss, a string of salvia connecting him to Denki. Denki whimpered, chasing Izuku’s lips but was only met with a soft chuckle. Without Izuku covering his mouth, the moans now began to leave Denki’s throat with ease as Katsuki ate his ass like it was his final meal before death’s row. The sound of slick hitting the ground was music to Izuku’s ears as well as the whimper-screams from his future omega.
“Omega, you’re enjoying yourself, I hope?” He asked, earning a simple whine. “You’re so cute. I can’t wait to breed you.”
That earned him a gasp. Izuku smirked. He had only said that because that’s what he heard omega’s supposedly loved from his friend, Eijiro. At least he knew the alpha wasn’t lying to him. Izuku hummed as he gently tapped Katsuki on the shoulder to grab his attention.
“Mm?” Katsuki pulled away, his lower half of his face drenched in slick. Denki whined in embarrassment at that, muttering on about Katsuki needing to clean his face.
Poor Denki. He didn’t know how alphas loved to be drenched by their omega’s precious slick.
“We should fuck him now before he falls asleep on us.” Izuku said, laughing at the eager smile on Katsuki’s face. Katsuki quickly stood up and carried Denki to his bedroom, not waiting for Izuku to follow close behind. Denki mewled as his back touched the cool silk bedsheets while Katsuki and Izuku began to strip.
“Denki,” Katsuki said. “We’ll fuck you one at a time, alright? Just so next time, we can fuck your pussy at the same time.”
Denki gasped at the mention of pussy and looked away embarrassed as more slick gushed out of his gasping hole.
“Ah, do you like this being called a pussy?” Katsuki smirked, pressing his cock against his puckered hole, earning a silent scream from Denki. Izuku leaned over and grasped Denki’s hand as he released more of his scent to make sure the omega was calm.
Katsuki grunted as he pushed inside bit by bit, earning a a mewl of pleasure from the smaller male. Being six inches was a lot, especially for a virgin. Izuku muttered sweet words of encouragement in the omega’s ears, tightening his grip on Denki’s hand.
“You’re made for this, Omega. You can handle it.”
“Yeah, you’re so good for me, Omega. So good.” Katsuki grunted, finally able to push in his entire length. He sighed as he slowly thrusted in and out. Izuku gave him a smile at his ability to be calm as Denki’s back arched in pleasure. His toes curled at each press on his prostate, moaning at the feeling of a real cock deep inside of him.
Katsuki sighed in relief, “I’ve missed the feeling of pussy like this.” He grasped Denki’s waist and began to pick up the pace of his thrusts. Denki cried out, blabbering about feeling too good. Each cry coming from the omega caused both alphas to groan. The feeling of seeing your omega enjoy sex was something every alpha dreamed of.
“Alpha, Alpha!” Denki whined, his tongue sticking out as drool left his mouth. His pink lips was still wet from the heated kiss he shared with Izuku and his pussy drenched in slick. Denki’s two inch cock bounced dejectedly as neither alpha paid it no mind. It was something most alphas followed religiously from practices from the past.
Never make an omega come from the cock.
The cock was simply there to be a decoration or a masturbation tool for an omega.
“So good. So good for me, Omega. You’re so fucking tight.” Katsuki groaned, feeling himself come close. It was normal since he hadn’t fucked an actual omega in at least four years since he had been dating Izuku.
“Inside, inside! Alpha, please! AHH~!” Denki screamed, his cock bursting as he cummed on his shirt.
Katsuki glanced up at Izuku for approval.
“You heard the omega, Alpha.” Izuku said, knowing that Katsuki loved hearing him call him that.
And true to that, in two harsh thrusts, Katsuki pushed in as deep as he could as he cummed inside. Denki sighed at the feeling of being full as Katsuki pulled out, watching his cum leak out mixed in with the slick. It was big globs of it as well. He was shocked it was so thick since it wasn’t like he hadn’t cummed in a month or something.
“Are you ready for bed, Denki?” Izuku smiled.
Denki whined, “no! Fuck me, Alpha!” He cried, big drops of tears falling from his clouded golden eyes. “Breed me. I want it. Deep, deep!”
Izuku and Katsuki blushed as Denki shockingly turned himself around to have his ass face Izuku. He laid down on his back as his head laid down on Katsuki’s laps. His legs were spread apart as he reached down and pulled his ass cheeks apart, shivering at the sudden rush of slick and cum slipping out of him.
“Denki…”
Izuku gulped.
He should wait.
Denki needs to rest a bit before taking Izuku. Izuku was like eight to nine inches. He made Katsuki look like a dwarf, especially from how thick he was. Katsuki was more skinny while Izuku was a thick as a soda can.
“Izuku, his heat is here.” Katsuki said, caressing Denki’s cheek as the omega purred in his lap.
Izuku’s eyes widened, “we sent him into heat?”
He had read about stuff like that but he never believed that he and Katsuki could do that themselves.
The omega whimpered as he stared at Izuku with want, shaking his ass invitingly. Izuku groaned before noticing the wet spots in Denki’s shirt. He reached over and pulled the shirt off of the omega, eye’s widening at Denki’s nipples that were leaking with….
.
.
.
.
MILK?!
“Huh?! How the fuck?” Katsuki muttered. Izuku leaned down and kept eye contact with Denki as he gently grasped the small breast in front of him and covered the pink nipple with his mouth. Denki stared at him in awe as Izuku began to suck, earning whimpers from the omega. Izuku watched in wonder as milk filled his mouth that he was able to safely swallow. Denki cried out, pulling at his free left nipple.
Male omegas rarely had breasts but if they did, it was at most an A cup and rarely a B cup. Denki looked to be almost a B cup. When he gets pregnant, he might get a C cup. Izuku bristled in excitement at the future of Denki filled to the brim of pups and accidentally bit the nipple, earring a hiss from his omega. Izuku hummed out in apology before pulling away, a small dribble of milk still on his chin.
“You’ll have to try it later, Kacchan. It’s my turn.” Izuku smirked.
Katsuki pouted but only hummed, leaning over to kiss Izuku on the lips. “Fine, but only if you make sure to repay me with my deserved cock in the morning.”
“Promise, Kacchan. I love you.”
“I love you too.”
“….love…”
Katsuki and Izuku stared down at Denki who looked to be on the brink of sleep as he muttered out what they could only assume was an ‘I love you.’ Izuku smiled softly at the omega and pressed a chaste kiss on his lips as he guides his aching cock towards the pink puckered hole that was vastly ruined by Bakugo Katsuki’s cock.
“Don’t take too long, he’s almost falling asleep.” Katsuki muttered.
Izuku hummed as he gently pushed inside, grinning at the sudden form of Denki’s lips that was still glossy from their make out. The thrusts at first was slow. It was only fair he followed what Katsuki did. Izuku could hear Katsuki mumbling calming words for the omega as he rubbed his scent gland. Denki’s soft moans was heard as the omega’s back arched once more.
Denki could feel himself widen than ever from how thick Izuku was. No other alphas could ever compared to them and he desperately wished this could last forever. He hadn’t noticed that he began crying until Izuku stopped his thrusting.
“Denki? What’s wrong?” Izuku stared at him, a look of worry etched onto his beautiful face. His freckles that dusted his face was less noticeable in the darken room but he could still tell that it was there.
“Nothing. I’m just sad for when this ends,” he laughed.
Katsuki grasped Denki’s face, making him tilt his head backwards to look him in the eye. “Who said this was going to end?”
“Yeah, are you planning on leaving us, Denki?” Izuku asked, continuing his thrusts.
Denki gasped, “no! But you guys are already a pair! I thought this was just a new threesome idea for you guys!” He cried, his inner omega crying in fear.
“Well, we’ll tell you now. Your ours forever and you will give us the prettiest pups in the world,” Katsuki smirked.
“Pups?!”
“Don’t act like you weren’t crying to be bred!” Izuku grunted, picking up the pace as Denki screams. He knew he wasn’t lying. Gosh, he hated how he got during his heat. It was a shock he was even fluid enough to speak right now. He stared at Katsuki and then turned his attention over to Izuku who looked to be close. His jaw was clenched as his hands gripped tightly at Denki’s thighs.
Denki brought his hand down to his stomach and circled his hand around it, glancing up at Izuku who stared at him with wide eyes.
“Breed me, Alpha.”
That was all it took before Izuku pushed Denki’s legs upwards towards his head as he pushed in as deep as he could. Each thrust and slap of skin was music to Katsuki’s ears as he felt his cock twitch alive once more. He gently grasped his cock and began to jack himself off, watching in interest at the beautiful sight in front of him.
“C’mon, bite him.” Izuku grunted, letting go of Denki’s legs and pulling him upwards. Katsuki leaned in on the left side of Denki’s neck while Izuku was on the right. Somehow, with the strength of his thick thighs, Izuku was able to still thrust harshly inside him.
Denki cried out as he blabbered on and on about having their pups. Izuku pushed in one last thrust and bit down harshly, Katsuki right behind him as he bit the left side. Denki screamed out as he felt his eyelids become heavy from the intense pleasure he had felt.
The broken skin had blood drip, telling the two alphas that the mark took. Katsuki smiled, blood staining his lips as he leaned over and kissed Izuku. The two could taste Denki on the other’s lips and couldn’t help the smile on their lips. They pulled away and sighed before Katsuki realised that Izuku hadn’t pulled out yet.
“You don’t have to stay inside him that long y’know.”
Izuku blushed. “Yeah that’s true.”
“You knotted him, didn’t you?”
“Yeah….”
“Oh for fuck sakes, Deku!”
Denki giggled to himself at the harsh red marks on his neck that he saw in the mirror from a week ago. It still hadn’t healed yet but in his mind, he loved it. He felt so happy that he scored such two hot alphas and that he was about to move into the apartment Izuku lived in.
He had a better job than both Denki and Katsuki so of course he had a better apartment. God, he couldn’t wait for next week any longer. Denki grinned, ah, he should drink some wine as a celebration!
Denki walked to the living room where Izuku laid on the couch watching some superhero movie. Katsuki was in the kitchen, making some ramen noddles as he smiled at his mate. Denki giggled as he kissed his alpha on the cheek before pulling out the wine from the cabinet. Katsuki stared at him in shock as Denki grabbed a glass to pour in.
“That’s for Izuku, right?”
“Huh? No, it’s for me. Why?” Denki said, pouring a halfway glass. He grasped the glass and was ready to bring it to his lips until Katsuki quickly pulled it away from him.
“Hey! Careful, it might spill!” Denki whined.
Katsuki glared at him. “You could hurt our pups like that, Denki!”
Denki blinked. “What pups?”
Katsuki stared at him blankly as he cursed underneath his breathe.
“Kats….what the hell are you talking about….?”
“It’s Izuku’s fault!” Katsuki yelled before running away.
Denki flushed in anger. “Come back here, you useless knotheads!”
