He could have sworn he tapped “Shitty Hair” and not “Shitty Nerd.” Damnit, he shouldn’t have them spelled so similarly. What the hell was wrong with him? The blonde knew he’d make that mistake one of these days, but he did NOT think it would be today. How does he get out of this?
“Kacchan? Are… you still there?” Izuku asked, sounding a little concerned

“Yeah. Yeah, I’m here.” Katsuki said chuckling awkwardly as his anxious scent that smelled like charred wood filled his room

Shit, his hands are getting really sweaty. He carefully wiped one on his+
sweats then traded his phone to the dry hand so he could wipe the other.

The Enigma put the phone up to his ear again.
“Just ignore what I said. I was talkin’ about a different Deku… that was… doin’ squats… in the… gym.” Katsuki said realizing how absolutely stupid that+
sounded

His eyes shut and his face scrunched up as he mentally facepalmed. You stupid moron he’s never gonna believe that bullshit! Katsuki’s Enigma internally shouted at him. Unfortunately the blonde had to agree

“Uh anyway, call you back.” Katsuki said rushed and hung up+
immediately

He stared at his phone screen after exiting out of the call app and saw Izuku’s adorable smiling face. Of course his Home Screen was the nerdy Omega! Who else would it be? Izuku was his best friend aside from Eijirou. And sure, Katsuki kept his phone locked with a+
passcode so no one would see it, but that was because people would make fun of him if they saw it. Not that he cares about getting dunked on, but it gets annoying after a while and no way in hell would his friends let it go. Now though? He’s reconsidering everything. Maybe he’s+
like Izuku all along and just didn’t realize it until that fat ass was straining in those unbelievable tight shorts that were definitely like three sizes too damn small.

Katsuki plopped back on his nest tossing his phone to the side as he looked up at the white ceiling. Not to+
be dramatic, but the blonde contemplated heading to the roof and taking a swan dive off so he doesn’t have to face Izuku later. How could he have been so careless? Now the other is going to think he’s a grade A pervert like Minoru. Shit, but it wasn’t his fault. Izuku was there+
lifting the stupid dumbbell while doing squats in nothing, but tight shorts. What was, an apparently, VERY homosexual guy supposed to do? Not look? Not appreciate? Not have his gay awakening? It was impossible! Izuku was all sweaty, with flushed cheeks, and his stupid curls were+
sticking to his forehead as he faced the mirror while making sure his form was right. Then he would squat low with the dumbbell on his shoulders while chatting. Not only that, but his scent was delicious. It smelled like a forest in spring. So sweet. The only unfortunate thing+
about the situation was that Todoroki, the dumb Beta, was there spotting him and not Katsuki. That stupid Icyhot got to be up close and personal to the miniature power house of a god that was Midoriya Izuku, a prime Omega, dressed half naked in the gym lifting ten times his+
weight! Fucking hell. Why was he cursed? Katsuki shifted uncomfortably because his little Kacchans were starting to make an appearance. Well he wasn’t little, but whatever. That’s not the important part. He needs to think about how the fuck he’s going to get himself out of this+
situation. What if Izuku didn’t believe him? What if he asks about it? Excuses people, he needed better excuses for every scenario that might come up about his stupid mistake.

“Ugh!” Katsuki huffed as he sat up while his brain ran rampant through every possible outcome
He glanced at his phone and snatched it up looking for Eijirou’s contact information after unlocking it. Katsuki made SURE he clicked the right name this time and put the phone up to his ear waiting for the red haired idiot to answer him.

“Bakubro what’s up?” Eijirou said+
sounding a little out of breath

Katsuki frowned.
“What the hell’re you doin’?”

“Nothin’ much just makin’ out with my girlfriend.” Eijirou said and Katsuki could hear Mina giggling in the background

The blonde rolled his eyes. Barf. Straight people. They’re been together since+
second year and now as third years they can’t keep their hands off each other. Katsuki sighed gearing up to deal with their idiocy so they can help him deal with his own.

“Well are you two knotheads done sucking each other’s face? I’ve got a problem.” The blonde huffed
If he could talk to Izuku about his troubles then he would usually turn to Eijirou. The redhead was an Alpha and offered good prospective sometimes. Other times he was no help at all.

“We can spare a few minutes.” Eijirou chuckled and Katsuki rolled his eyes

“So what’s wrong?”
The Alpha asked

Katsuki frowned trying to figure out how to explain but he thought it best to be honest so he was.
“I was trying to call you, but I ended up calling Deku and told him that I had my gay awakening when I saw him do dumbbell squats in the workout gym.” He said and+
waited only to be laughed at by Eijirou and Mina

“SHUDDUP!” Katsuki roared

“Okay, okay. Sorry man.” Eijirou said trying to hide his chuckling

Katsuki grunted in annoyance.

“Let’s back up for a second. You said you had your gay awakening?” The Alpha asked
Katsuki sighed.
“Yes idiot.”

“Okay, but I thought you already knew you were gay?” Eijirou said

“Wait he doesn’t know he’s gay?” Katsuki heard Mina ask

“What the hell do you mean?!” The Enigma questioned as his eyes went wide

“Uh well you always say that girls and Omegas are+
annoying. So we just assumed you didn’t like females or Omegas.” Eijirou said

“Or female Omegas.” The Pink Prime Alpha added

“Yeah.” Eijirou told him

(TBC?) Not sure where I’ll head with this.

Big thanks to @SomaHoliday23 for letting me do this though 😊. Go follow them!
Credit to a few commenters for ideas on dialogue lol.
Katsuki pinched the bridge of his nose. Okay yeah girls were annoying to him and Omegas usually were too, no matter their primary gender. However it wasn’t because he was sexist some guys were just as annoying, no matter their secondary gender. The issue is that Katsuki has+
never looked anyone’s way. He’s never found anyone that could catch his interest. He never liked anyone’s smell more than just tolerating it. The Enigma’s nose was sensitive so he tended to scent others a lot to dull their smell. Well if they were close like his pack.
He’s scented Eijirou, Mina, Hanta, Denki, and Kyouka. They were all different genders and had different smells, but after being around them for three years he no longer had to soak them with his own scent to be comfortable around them. And as annoying as they were Denki and+
Kyouka who are both Omegas aren’t too annoying to be around and they liked to be scented. Hanta is a Beta so his smell is pretty muted anyway. Eijirou an Alpha and Mina a Prime Alpha, they were the ones Katsuki usually overly saturated with his scent. Now their river rocks and+
cotton candy smell didn’t bother him much. Hell Katsuki was okay with most of the classes scents and well he’s always been okay with Izuku’s. Now that he thinks about it the Prime Omega has only ever caught his attention in such away. Even when they weren’t on good terms they+
couldn’t stay away from each other. When he had his first rut he remembered his mother telling him he couldn’t go over to the Midoriyas because it was too dangerous for himself and Izuku. Had he liked the Omega this whole time? Had he… imprinted on him when they were young?
“Yeah typically girls are annoying as hell, but not all of them. Not all Omegas either. Don’t assume from just that!” Katsuki told him

“Right sorry bro. Uh, but I was technically right though.” Eijrou pointed out

Katsuki gritted his teeth because yes the stupid Alpha was right.
“Not the point! The point is I’m gay and I just told Deku I was looking at his ass! How the hell do I get out of the situation without gaslighting him!?” The Enigma shouted as he got out of bed

“Why can’t you just be honest? If you like him just ask to court him.” Eijirou+
suggested and Katsuki could see him shrug

“Do you hear yourself? Me date Deku? No way in the seven realms of hell would I ever court his nerdy… plump… ass- damnit.” The blonde said then shook his his head to shake away the dirty thoughts his Enigma was sending him
Eijirou chuckled.
“You’re so whipped.”

“Shuddup, I’m not!” Katsuki told him

“Lemme talk to him.” The blonde heard Mina say

“Alright.” Eijirou replied to her

“Look Blasty. Sorry for assuming you were gay even though we were right.” Mina started and Katsuki grumbled at that
“But honestly the reason why we thought that other than thinking girls are annoying was because we thought you liked Izuku.” She said

“Hah?” Katsuki frowned confused

“Oh c’mon. Your relationship with him is like way deeper than anyone else’s and after first year you two have+
practically been attached at the hip. Or knot.” Mina giggled and the blonde scrunched up his nose glancing down at his crotch

He quickly looked away dismissing the thought of himself mounting Izuku. He’s never seen Izuku naked. Well he has but that was when they were little+
kids, before Katsuki got his quirk and knew what their secondary genders were. When he found out Izuku was an Omega he wasn’t really surprised but when he found out he changed into a prime Omega after receiving One For All that caught him off guard. Female prime Omegas are+
extremely rare but male prime Omega are basically unheard of. Much like Katsuki himself who’s an Enigma. In this day and age male Omegas were uncommon, but not really rare. There were more female Omegas than male. Even in their class Denki Aoyama were the only other male Omegas.
The rest were Beta, female Omegas, or Alphas. Prime Omegas and Enigmas were a lot a like. They both nest, they both like scenting or having scented things for their nest, and they both have heightened senses. Only difference is Prime Omegas can get pregnant and no matter the+
primary gender they have a pussy allegedly. Enigmas on the other hand have two dicks even if they’re female. Now Katsuki doesn’t know if Izuku has a cunt since he’s never seen him naked after they presented and honestly he doesn’t remember much about bath time when they were+
kids. Male Omegas like female Omegas, prime or regular, have their own bathroom same with female or male Betas. Then Enigmas, Prime Alphas, and Alphas use the same bathroom respectively of their primary genders. The locker rooms are the same so Izuku always changed in the male+
Omega locker room and he bathed in the male Omega bathroom. Heck even in the dorms different levels were for different genders including their primary gender. So Izuku, Aoyama, and Denki were on their own floor. Same with Kyouka, Tooru, and Ochako on the female side.
Katsuki’s never even been on Izuku’s floor in his room. If they sparred it was in a gym or outside. If they studied together it was in the common area. The only reason Katsuki knows what Izuku’s room looks like is because they send pictures back and forth sometimes.
Now he really wants to be in that room. See that nest. Smell that everything is saturated with Izuku’s Omegan scent. Son of a bitch and Katsuki’s mom was definitely a bitch.

“Tch- we are not that attached. Definitely not at the knot.” Katsuki frowned

“Oh but I bet you wanna be+
now.” Mina giggled

“I hate you.” Katsuki huffed

“Love you too. Anyway you do need to chill. You don’t wanna scare Izuku off by being a creepy Enigma. That’s why Minoru doesn’t get any Omegas.” Mina told him

“I wasn’t-“ The blonde started to defend himself
“It wasn’t on purpose. I just walked into the gym and he was right there.” Katsuki murmured as his Enigma whined feeling bad

“I know, I know. Izuku has ass for days so honestly I can’t blame, but you can’t be drooling all over yourself because of it.” Mina giggled

Katsuki just+
rolled his eyes with a click of his tongue.
“I don’t do that shit. I just panicked and left.”

“Well you said you needed help with your problem but you don’t wanna fess up so how exactly do you expect Izuku to just forget what you said?” Mina asked

“I don’t know. I don’t want+
him to feel uncomfortable and shit. Maybe if we pretend I didn’t say it things won’t be awkward.” Katsuki shrugged

“Oh Katsuki…” Mina said and the blonde frowned

“You think Izuku wouldn’t present for you if you asked, don’t you?” She asked

Katsuki’s eyes went wide. Asking an+
Omega, even if they do it without you asking, to present for you is a great honor. It usually only happens between partners if the Omega is accepting of you and feels safe to let themselves be so vulnerable.

(TBC) This is a little all over the place I think 😆 sorry!
(CW/TWs: Height difference/Simpkugou/Izuku is dense, but not really.)
So the thought of Izuku, sweet Izuku, being face down ass up made his cocks twitch hard. The blonde flushed a little, but tried to school his face. He’s practically a grown man not some schoolboy.

“No he wouldn’t! Deku wouldn’t do that for anyone.” Katsuki denied
“I bet he would if you asked him too.” Mina said in a sing-song tone

“Well I’m not. That’s weird and we’re not even dating.” Katsuki told her

“Then court him.” Mina replied

“I can’t!” Katsuki shouted annoyed

“And why not?” Mina questioned

“Because-“ Katsuki started but he+
didn’t have a good answer other than he just couldn’t

They were friends, he just realized he might like Izuku, and they’re graduating soon. He can’t just spring this on the Omega when he himself barely has whatever the fuck this is together. All he knows is Izuku has a fat ass+
and he wants to put his face between those humps. Jeez he needs to be careful or someone might muzzle him. Maybe talking to the idiots was a bad idea.

“Because?” Mina implored

“It would just be weird.” Katsuki frowned

“I don’t think so. It’s not like you’ll be asking to+
collar him. Just do something small like give him your shirt. You never know he might return the favor then you jack off all over his sweet smelling shirt.” The prime Alpha suggested

“Mina!” Katsuki heard Eijirou say in shock making the pink woman laugh

The blonde gulped. This+
wasn’t helping it was just making another issue arise.

“Fine maybe don’t pop a knot all over it but at least you can add it to your nest. I’m sure he’ll do the same.” Mina said then suddenly got excited

“Oh oh, maybe he’ll give you some boxers or panties. Wait does he wear+
panties? Maybe we should ask Denki. I bet he knows.” The Alpha said

Katsuki sighed as the two kept talking back and forth so he decided to just hang up. He’s not sure why he thought they could help him with his predicament with extra dick. He once again plopped on his bed in+
the middle of his nest made with many clothes borrowed from his friends. He’s never asked to have something of Izuku’s grabbed outside his friends he also doesn’t ask anyone for their clothes. Katsuki would like to have something that smelled like Izuku though so maybe offering+
a scented shirt and hoping to get one back wouldn’t hurt.

His phone dinged and he frowned lifting it up over his face so he could see the notification. When Katsuki did though he heart dropped. It was a massage from Izuku. “Can we spar later?” Was all that was asked but Katsuki+
knew it was just a ploy to get them alone so they could talk. The blonde wasn’t stupid. Izuku isn’t slick and unfortunately Katsuki couldn’t deny it either. It would look worse. Dodging the situation would only end up in them being upset at each other so it’s best to just be+
honest. Even if it feels like his world that had just started might end.

Later after putting on his gym uniform Katsuki headed out of the dorms towards the grassy open area in the mini forest that was on campus. The two liked training there during the summer. When he got+
to the clearing he saw Izuku standing in the center looking at his phone with a small smile. It was cute but goddamn he was wearing those tight ass shorts that hugged his thick thighs. Seriously was Katsuki blind as a fucking bat? How did he miss all of that before?
Suddenly Izuku’s lifted his head up sniffing heavily then the two made eye contact and Katsuki jolted a little. Izuku just giggled.

“Kacchan you look like a scary wolf hiding like that.” He said

Of course Izuku could smell him from that far away. Hell Katsuki could smell the+
Omega from where he was. Though with them being in a forest Izuku’s scent was masked a little by the actual forest smells. Katsuki regular scent was a chili chocolate smell. Some say it’s too sharp sometimes because of the spicy aspect, but some say it’s sweet because of the+
chocolate notes. Katsuki never really cared, but now he’s wondering if Izuku likes his smell. He likes Izuku’s. He likes it a lot.

“Tch-“ Katsuki clicked his tongue as he stepped over a large bush and entered the clearing

“If you start saying “what big arms you have, what big+
legs you have.” The blond mocked in a higher pitched voice

“I’m actually gonna eat you.” He added, walking towards the smaller

“Guess that would cover the “what big teeth you have” part.” Izuku giggled

Prime Omegas were a little taller that regular Omegas even though all came+
in different sizes. The interesting thing was that they could pack on muscle like no other Omega which is why Izuku was a fucking brick house even with his small size. So Izuku was nearing six foot, but not quite there. He was five-ten. Katsuki however was an Enigma so he was+
exceptionally tall, seven-five to be exact which was only two inches taller than All Might, but the guy was also an Enigma. Well he was before One For All was passed to Izuku. Now the older blonde was back to being a prime Alpha. Still though Katsuki is now realizing how much he+
likes their height difference even if it causes complications for himself in his daily life.

Then suddenly Katsuki realized a mistake he made.
“I meant beat you!” He blurted and Izuku started laughing

Unfortunately it was basically music to his ears hearing the Omega laugh+
even though it was directed at him. Katsuki’s Enigma whined that He corrected himself because apparently he did want to eat the Prime Omega, but not in the cannibalistic way.

“Shuddup.” Katsuki huffed, but it wasn’t a command

He would never do that to any Omega if he could+
keep from it much less Izuku.

“Sorry Kacchan.” The smaller said as his laughs fizzled out

“Tch-“ Katsuki scoffed crossing his arms over his chest

“Can we just get on with it? We just sparring or do you need help with something?” The Enigma questioned

“Well I do need help+
with something.” Izuku looked up at the other

Katsuki sniffed the air a little, but couldn’t tell if anything changed. Izuku smells as he usually does.

“What is it now?” He asked

“Why don’t we sit down?” Izuku suggested as he went ahead and moved to his knees
Katsuki backed up a little so they weren’t so close. They weren’t in the first place but he just felt like he needed to as Izuku kneeled on the ground. Unfortunately his Enigma supplied a picture of Izuku on his knees sucking his cock while jerking the other off with his scarred+
hand and damn was that a good image but he couldn’t run with it since it would make his scent full with arousal. One thing you don’t do is get randomly horny in front of an un-consenting Omega, of any kind. It’s gross knothead behavior and Katsuki is more sophisticated than that.
Speaking of sophisticated.
“I ain’t sitting on the dirty ass-“ He started to say only to be interrupted by Blackwhip yanking him down by his waist

“Kacchan sit.” Izuku replied like he was talking to a dog

Katsuki had the displeasure of knowing his Enigma found pleasure in the+
command. It wasn’t a true command though. Prime Omegas can actually make commands, but it only works on regular Omegas, Betas, and Alphas. It which means it doesn’t work on other prime Omegas, prime Alphas, and Enigmas. However it doesn’t work all the time. If the regular Alpha+
is strong enough they can dismiss the command.

The blonde sank to his knees with a grumble as Izuku smiled happily after Blackwhip dissipated.
“Don’t fuckin’ tell me what to do!” Katsuki barked annoyed

“Sorry.” Izuku giggled clearly not sorry at all and it made the Enigma+
grunt in displeasure

Izuku was sitting on his knees making the already short shorts ride up a little more. Katsuki wondered how they weren’t strangling his dick until he remembered Izuku might not have one. It would probably still hurt though. He’s heard girls whine about+
underwear that’s too tight. Whatever it’s not important.

Katsuki sighed.
“What do you want Nerd?”

Izuku looked at him sternly.
“First no running away or I’ll use Blackwhip to drag you back.” He warned and Katsuki frowned

He neither wanted to admit or not admit he found that+
kind of hot. Like what if Izuku used it to strap the blonde to a bed as he rode his cocks using those powerful legs until they both came- fuck! Control! Control yourself! Katsuki shouted internally because seriously what the hell was wrong with him? What he going into rut or+
something? He’s never thought about sex this much. That’s not to say he never thinks about it. He watched his fair share of porn and had a pretty good imagination, but every five seconds when he was around Izuku was just uncalled for. He typically keeps up with his ruts so he+
should check it later because being overly horny is a sign of pre-rut. It’s too dangerous for him to let it go unchecked. Not that he would hurt anyone, but things can get out of hand which is why he needs to lock himself up in his room if it’s getting close to time.
“Fine.” Katsuki huffed trying to stay calm

He’s not a fan of having rut. It’s tiring and not pleasant really so dreads when the time comes. But maybe this could be a good excuse to ask Izuku for something scented to put in his nest? That’s not weird right? Izuku has asked for+
scented clothing before from him and other classmates. So it should be fine if Katsuki asked.

“Okay good.” Izuku smiled as he fiddled with the hem of his stupid “hiking” shirt

Katsuki got that for him during Christmas last year.

“Um I know you said to ignore it, but I can’t.”
The smaller started nervously and Katsuki could smell it

When Izuku was nervous his forest in bloom scent change to a autumn smell. Like crunchy leaves that have fallen that the crisp air pushed towards anyone who was around’s nose. Katsuki frowned as his Enigma started to+
worry. Omega nervous, comfort Omega. It demanded which lead to Katsuki pushing out his warm milk chocolate scent that comforted most people.

“I wanna know what you meant when you said that over the phone.” Izuku finished, looking at Katsuki who blanked

He knew it was coming.
He knew but he wasn’t prepared. On shoulder a devilish Dynamy popped into existence saying he should lie while on the other shoulder an angelic Dynamy appeared saying honesty was the best policy. His brain fought a tough battle, but in the end the honesty won and both Dynamys+
disappeared. Damnit. Now he has to be truthful.

“I uh… figured out I’m an ass man.” Katsuki stated

Izuku flushed a little.
“What?” He asked confused with a cute slight tilt of his head

“I kinda panicked earlier when I meant to call Eijirou, but called you instead. I’ve never+
really payed much attention to peoples bodies unless it was in porn ‘cause obviously.” Katsuki rolled his eyes as Izuku seemed to be focused on listening

“Anyway for whatever reason today when I walked into the gym and saw you wearing those tight shorts it kinda jump started+
some. A sexual awakening I think even though my libido is far from low. I don’t really know what to call it but your ass looked good in that moment and it freaked me out.” The blonde chuckled a little like it was funny

“I don’t wanna make you uncomfortable though. It probably+
could have been anyone but it just happen to be you.” Katsuki added not wanting Izuku to feel like he was unsafe around the blonde

Unfortunately there were a lot of bad Alphas out there that would take advantage of Omegas whenever they could. Katsuki would never do that nor+
want an Omega to feel like he would. Again he was more sophisticated that that.

Suddenly Katsuki was dragged from his thoughts by a slight sour smell. Like rotting wood. He looked at Izuku who had a strange expression on his face only for it to turn back to normal.
“I get it Kacchan so don’t worry.” He said placing a gentle hand on Katsuki’s forearm

The blonde wondered why Izuku smelled as if he disliked something greatly. There was notes of disappointment.

“I just uh don’t want you to feel unsafe or whatever.” Katsuki said almost+
dismissively

Izuku offered a small soft smile.
“I would never feel unsafe around you.” He told him

If you knew the shit I’ve been thinking about all day you would feel different. Katsuki thought, but nodded.

“Just forever about it alright. I was being dramatic and I think my+
rut is near. You know how I get.” Katsuki said waving his hand in the air for emphasis

Something seemed to click in the Omega’s head because he nodded.
“Oh yeah. It’s in a week or so.” Izuku said and it made Katsuki frown

“Deku how the hell do you know that?” He asked
Izuku then flushed.
“Well I- I keep up with everyone’s heats and ruts especially friends so I can give comfort items.”

Katsuki looked the other up and down for a moment.
“You’ve never given me anything.” He pointed out

“Kacchan‘s never asked.” Izuku retorted

“So?” Katsuki+
frowned confused with a shrug

Izuku rolled his pretty eyes.
“So it’s not really appropriate for Anna omega to just give something to an Alpha or Enigma without being asked.” He argued

Katsuki chuckled in disbelief.
“You’re shittin’ me. Since when do you do literally anything+
by societal rules?” He asked

Izuku sighed and pouted.
“I do some things by societal standards you know?”

“Why?” Katsuki frowned

“Because I like to.” Izuku told him

“You like to?” Katsuki repeated confused

Izuku nodded.
“Yes, I like to be asked personally when someone wants+
a scented item me. It makes me feel wanted.” He said looking over at Katsuki who seemed to be considering it

The blonde didn’t think about it that way. He thought of it as more of a chore. He didn’t even like asking when he needed scented items for his nest, but thinking about+
it like that makes him reconsider things. Maybe that’s why his friends were happy to supply. When Katsuki asked it made them feel like they were wanted. The blonde seemed to be surprised by the revelation that probably should have been obvious. Maybe Izuku would like it if he+
asked then. He planned to anyway so now was the perfect time.

“Then can I have a scented item from you Deku?” Katsuki asked as Izuku whipped his head around to look at the other in shock

“You want me to scent something for you?” The Omega asked and Katsuki nodded

(TBC)
Izuku smiled with a blush as he wiggled his butt a little. The Omega did that often when he was excited or really happy about something.

“Of course Kacchan! Do you want just one or two or three or-“ he said his his sentence started to run off into muttering as usual
Katsuki sighed. Why did he like him again? Oh yeah. Because Izuku is the kindest and most beautiful person he’s ever encountered. Sometimes he can’t even believe they’re friends again. Even though they’ve resolved a lot of their baggage in second year they’ve only really been+
real best friends again since the start of their third year. So a lot of what they did was knew for a second time. Especially asking or receiving scented items. He’s never had the opportunity to give Izuku something of his that was scented so maybe he should offer something.
“Just one will do. I’ll get stuff from the idiots too so don’t worry about it.” Katsuki said and Izuku seemed to immediately stop as he looked at the blonde

“From Denki and Kyouka too?” He asked

Katsuki frowned slightly.
“Uh yeah. I usually do.”

Izuku glanced away.
“Oh…” He+
said and there was that smell again, rotting wood.

Was he making the smaller upset? Why would Izuku care what’s in his nest. Especially for his rut. He’s not sure what’s going on but maybe he should ask. Before he could though Izuku looked at him and smiled as the smell+
changed back to its normal scent.

“Well are you sure you don’t want more than one thing. I don’t mind to give you more.” The prime Omega offered

“You won’t have to bother with the others then.” He added

Katsuki looked at the other for a moment. Now it sounds like he wants to+
fill the blondes nest with his scent? Most Omegas would never offer such a thing. Was Izuku being… possessive? Possessive over what? Oh wait. Denki and Kyouka. They’re Omegas and since Katsuki asked Izuku about scented items maybe he thinks he needs to compete or offer more+
stuff because he’s a prime and not a regular Omega. Katsuki does know, but he’s sure Izuku is acting possessive. The blonde knows Omegas can get that way over friends family or significant others and especially their pups but Why would Izuku get possessive over him because of+
other Omegas that were also his friends? Typically he would call it out but now the prime Omega was offering more clothes of his own volition so would it be bad to accept?

Katsuki glanced to the side with a shrug.
“I mean if you want to then site I guess, but you don’t gotta+
trouble yourself.” He said as his Enigma begged him to just say a firm yes

Damn that part of him was so annoying. He never had such an active Enigma before. Sometimes he would pop in to say shit but it wasn’t often and definitely not as often as this. It really must be because+
his rut is soon. He can’t see another reason for the thing to be acting like this.

Izuku smiled scooting closer to the other and placing his scarred hand on Katsuki’s strong forearm. The blonde wondered what they looked like wrapped around his cocks, but quickly dismissed the+
idea because Izuku was too close for him to be having horny thoughts.

“It’s no trouble at all Kacchan I’ll give them to you tomorrow.” He chirped and Katsuki almost gave an approving chuff in return

“Alright then.” The blonde nodded and looked at the smaller
“Do you uh want me to give you something too. Feel like I should return the favor.” Katsuki added

Izuku smiled.
“If you want to, but it’s okay if you don’t.” He said with a shrug but was letting out a slight extra sweet flower smell signaling+
he was happy Katsuki offered

“Don’t like being in anyone’s debt so I’ll give you a shirt or something. That alright?” The taller asked and Izuku nodded enthusiastically

“Of course it is! It’s perfect!” He chirped again

Seeing his face so excited while smelling so happy made+
the blonde’s heart raced and his scent definitely shifted into a warm cinnamon roll in Autumn smell. He almost let out a rumble.

“Cool.” Katsuki said offering a small smile

The next day Katsuki was in his room trying to decide what to give Izuku. He raided his own+
closet to find something his Enigma would pleased with giving to the Omega, but it seemed like nothing was right. After their little talk yesterday he and Izuku actually sparred and it helped him clear his head a bit. When he got back to his dorm Mina had called him because of+
course she was spying on them the whole time. He ended up telling her about the agreement which he was way more excited about than Katsuki was. After that he checked his calendar and yeah he was right. His rut was due but Izuku was also right because it should show up in about a+
week or a little more. That night he crawl into his nest after shutting out the lights and dreaded what was to come. However the next day he got up did is morning run and then made his way through his daily routine which lead him to sifting through his closet.
He wanted to give Izuku his scented item this morning rather than later, but with it taking this long he might need to wait. His Enigma insisted on finding something perfect. So he sighed stuffing his clothes back in and sliding the door shut. He grabbed his bag and headed out+
of his room since he was finished with everything. Just as he stepped out of his room he was confronted by Izuku who shouldn’t he on his floor. It wasn’t allowed and they could get in trouble.

“Deku.” Katsuki said seeing the small laundry basket he was carrying with a smile
It had to have a least ten shirts in it.

“Good morning Kacchan! I brought you the stuff you wanted.” Izuku said holding the basket out to the other who had put his bag down

“You’re not supposed to be here Nerd.” Katsuki said taking the laundry

Izuku rolled his eyes.
“It’s not+
like I’m going in your room. Being in the hallway is fine according to the rules.” He argued with a small grin

As Katsuki looked down at the basket since he didn’t have the patience to argue this early in the morning and the smell wafted towards his nose. Oh higher power was it+
fucking good; mouth watering. The smell of a prime unmated Omega would make anyone hard. Katsuki had to put the basket down when his Enigma was begging him to mate Izuku right then and there. That was way out of the realm of what was okay. Mating? They aren’t even courting each+
other, they’re just friends and Katsuki needs to get himself along with his knotheaded Enigma under control.

“Thanks o- Izuku.” Katsuki corrected himself when his Enigma nearly spoke for him

Izuku blushed releasing his happy scent.
“No problem Kacchan.” He said hugging the+
taller

They hugged often, but not too often. Katsuki liked to because he could get a a sniff of Izuku’s comforting scent without it being creepy. Though it made things hard when the smaller would press his nose right to Katsuki scent gland. Izuku’s always done that even when+
they were little and hadn’t presented yet, but doing it now made a lot of confusing feelings flow through the blonde. Now he realizes it was because he likes Izuku.

“I don’t have anything for you yet but I’ll give you something this afternoon. I was busy this morning.” Katsuki+
urging Izuku to move away a little before pops a boner or makes things awkward

The shorter wasn’t going to budge though as he smiled against Katsuki’s neck.
“It’s okay. You give me it whenever you want. No rush.” He told him

Damn being this close to Izuku scent was not helping.
Was it sweeter than usual today? It sort of smelled like freshly cut apples. Katsuki’s never smelled that scent before. He didn’t question it much as he himself pulled away first.

“Alright, I better get this in my room then.” Katsuki said leaning to grab the laundry basket and+
noticing Izuku was pouting a little

“Okay. I’ll see you at school then. I need to go catch up with Ochako anyway.” Izuku said as his pout morphed into a smile

Katsuki frowned, but waved it off.
“Okay see you later Nerd.” He replied

Izuku nodded heading off.

CW/TWs: Mentions of Shinkami, Kirimina, Momojirou, and Seroroki.
After Katsuki set the basket of clothes in his room, he headed off to the main building since school would be starting soon. He hates being late for class. On his way he noticed others were giving him strange looks which was only met with a glare in return then they would+
quickly look away. He got looks often, but typically it was from people whom were interested in him. It wasn’t questioning looks or looks of disgust. Katsuki just ignored them as usual and opening class 3-A’s large door then stepping in. He shut it behind him then walked towards+
where his friends were loitering at Denki’s desk. The electric blonde Omega was at his own desk sitting on Beta Hitoshi’s lap with Prime Alpha Mina and Alpha Eijirou right next to him along. Beta Hanta was standing next to Omega Jirou ok the other side of Denki’s desk.
When Katsuki arrived Eijirou turned to greet him first but paused and the others immediately looked at him too. Katsuki frowned as they all leaned forward to sniff the air around him.

“What the hell are you all doing?” He grunted annoyed

“Bro you smell off.” Eijirou said+
looking the slightly taller up and down

“Yeah for real.” Mina nodded

“It’s weird.” Kyouka narrowed her eyes, stepping back a little

“Not really. He smells like Izuku.” Hitoshi pointed out which was odd because he was a Beta

“Yeah I new it smelled familiar!” Denki nodded+
enthusiastically as his boyfriend

Katsuki looked down at himself confused.
“I smell like Deku?” He questioned sniffing himself

“Even we can smell it.” Hanta nodded gesturing between himself and the indigo haired Beta

Betas can’t typically smell scents unless they are+
especially strong which apparently the scent was because a Beta could smell it. What the hell did Izuku do to him?

“Yeah it’s super strong.” Mina nodded

“Wait did he scent you?” Kyouka asked sniffing Katsuki again then immediately pulling back

Katsuki rolled his eyes and+
scoffed.
“No way in hell would he do that without askin’.” He said

Izuku would never scent someone without consent especially not Katsuki. They haven’t scented each other in an extremely long time. Like when they were kids long time. Plus why would he? They were friends sure,+
but there was really no reason to scent each other. Unless Izuku had a reason that Katsuki didn’t know about.

Denki furrowed his brows as he got up and walked towards Katsuki who frowned down at him. The Omega was much shorter than him like Izuku. They were nearly the same+
height actually. Everyone watched as Denki suddenly hugged Katsuki. Hitoshi looked confused as to what his boyfriend was doing, but not pissed or upset. Katsuki tensed when the smaller hugged him. Everyone started to laugh at seeing his shocked face, but he just glared at them.
The ash blonde was about to hug Denki back when he pulled away before he could and stepped back a bit.

“Oh man.” He said looking up at Katsuki who has his arms out just a bit until he quickly put them down at his sides

“What’s the “oh man” for?” Hitoshi asked

“Is something+
wrong?” Kyouka questioned

“Yeah, what the fuck?” Katsuki frowned

“Dude he didn’t just scent you. He marked you.” Denki said as the others gasped

Scenting even heavy scenting could be significant or just casual but marking that was up there with claiming. It was like a+
promise ring almost. The Omega staked his claim and his claim was Katsuki. He didn’t understand. Seriously why would Izuku do such a thing. That was intimate. Only soon to be bonded couples did stuff like that. Not… not people who were just friends.

“No way.” Eijirou said in+
disbelief

“That’s so bold.” Mina giggled

“That’s crazy.” Hanta added

“Why would he do that?” Hitoshi said

Kyouka crossed her arms.
“No wonder why smelling you makes me wanna go to the other side of the room.”

“Yeah same.” Denki nodded covering his nose

“Can’t believe he+
would just do that.” Mina sat stepping forward to smell Katsuki then lurched back

“Jeez, it’s so strong when you’re up close.” She whined as Eijirou did the same only to be pushed away

“Alright, stop smellin’ me!” Katsuki huffed then sighed when the red head stepped back
“Don’t know why Deku marked me. We just hugged this morning after he gave me some clothes.”

“He gave you clothes?” Hitoshi asked confused

“Did he give you any panties?” Mina grinned

Katsuki flushed a little.
“No! And I… asked for them. My rut is soon. I just kinda wanted+
his scent.” He explained as his embarrassed burnt marshmallow smell started to seep out

“Oh.” Everyone said in unison knowing why the blonde asked for the scented items

Katsuki frowned looking at them.
“Don’t fucking “oh” me!” He growled

“Me reason to deny it we all know why+
you asked now.” Mina giggled

“Yeah, Eijirou spilled the beans.” Denki said and Hitoshi nodded

“Man, you said you wouldn’t tell him.” Eijirou whined

Great now all his friends know he likes the Omega and will probably never let him live it down. Just awesome. He never should+
have called Eijirou or Izuku for that matter then he wouldn’t be in this stupid mess. The only upside is that he had a basket full of Izuku’s laundry waiting for him in his dorm.

“Do you still need stuff from the rest of us though?” Hanta interrupted asking a serious question
Katsuki glanced to the side.
“Yeah if you idiots don’t mind.”

“We don’t.” They said

“Thanks.” The ash blonde nodded

“Are you gonna ask him about the marking?” Kyouka asked

Katsuki rolled his eyes.
“I’m sure there was a dumb reason. I’ll ask him later.”

“Don’t think there’s+
much to say. I’m pretty sure the reason he marked you is because he’s basically claiming you man.” Eijirou shrugged

“Yeah. Like when we scent each other.” Mina smiled over at her boyfriend

Denki nodded.
“Or I mark Hitoshi.”

“Momo and I do the same.” Kyouka pointed out
“Well Shouto and I can’t, but if we could we definitely would.” Hanta said since they were both Betas

“Okay I get it, but I doubt that’s the reason marked me. There’s gotta be another reason.” Katsuki told them

“Maybe.” Hitoshi shrugged

“I’m sure you’ll figure it out soon+
Bakubro.” Eijirou said as he patted Katsuki on the shoulder making him feel a little relieved that they wouldn’t be teasing him over Izuku’s weird behavior

The door slid open and he heard Izuku along with Ochako and Shouto chatting as they stepped in. Katsuki along with his+
friends looked towards them. Hanta walked past Katsuki to greet his boyfriend Shouto who smiled when the raven haired Beta approached him. Ochako waved to Izuku as she made her way to her desk where Tenya was already in his seat. The smaller walked towards his desk, but saw+
Katsuki looking at him with a frown.

“Oh hi Kacchan.” Izuku said walking up to him

“Are you not gonna take your seat? Aizawa-Sensei will be here soon.” He told the big Enigma

Katsuki wanted to confront him about the scenting, but not in front of everyone like this. It might+
embarrass Izuku or something. So he just scoffed.

“Like I give a fuck what he says. I was talking to friends.” The blonde told him

Izuku looked confused then shifted his body weight to peek around the Enigma.
“Friends?” He questioned looking back up at Katsuki
He immediately looked over his shoulder to see no one was there except Denki and Hitoshi who were now making out. Katsuki’s nose scrunched up as he whipped his head back around to Izuku.

“Emphasis on was.” He grumbled making the shorter giggle

“Let’s go to our seat.” Izuku+
told him as he grabbed Katsuki’s arm and pulled him to their seats

Once there Izuku pushed the blonde into his seat then went to his own. Kyouka was looking over as Katsuki from the corner of her eye and when he glanced her she smirked then looked towards the front as their+
Beta teacher Aizawa walked in. It was then Katsuki noticed that Izuku and Omega told him what to do and he just listend. Not only that but the smaller had onto his wrist. Right on his scent glands. Maybe he should buy scent blockers because he can smell his scent change to+
something proud pretty quickly. How embarrassing. His scent glands are acting like they’re knew and his Enigma is begging him to scent Izuku but he can’t without permission. He refuses to.

Class was boring as usual since they didn’t do any field work but while walking to lunch his mind was a battle field. Trying to decipher why Izuku, an Omega, a prime one at that, would scent him so… openly. It’s really not a big deal but Katsuki’s Enigma is telling him it is.
Maybe Izuku just didn’t like his scent so he covered him in his own or maybe the smaller didn’t like other people’s scent on him when he’s around so he covered it with his own scent. The latter sounds a little possessive though. Izuku isn’t possessive like that.
Seriously Katsuki can’t figured it the fuck out. Why would the Omega scent him without asking? Maybe he should ask Denki or Kyouka. They might have insight. He looked over to his left to see Kyouka talking about an old band with Denki so Katsuki interrupted them.
“Oi, you two.” The ash blonde said making the two Omegas look over at him

Mina and Eijirou were chatting behind them with Hitoshi. Hanta was off somewhere else with Shouto. They’re probably making out. They do that a lot. Katsuki thinks it’s gross to see them practically mating+
in public.

“Yeah?” Kyouka said looking bored

“What’s up Kats?” Denki asked seemingly catching the blonde’s concerns in his scent

“Got a question for you two. Since you’re Omegas I figured you’d know more than me.” Katsuki shrugged

The two’s eyes widened a little.

“Did you+
just admit we’re smarter than you?” Denki asked

“No!” Katsuki growled catching the attention of the two Alphas and the Beta

“I was saying you might know more than me since you’re Omegas not because you got any brains.” He huffed

“That makes more sense.” Denki nodded
Kyouka rolled her eyes not fazed by his insults.
“I have brains you know.”

“Tch. Fine you’re not that dumb.” Katsuki conceded

Denki perked up.
“What about me?”

“You’re dumb as shit Sparky.” Katsuki scoffed making the other blonde pout

“Don’t call me boyfriend dumb Katsuki.”
Hitoshi spoke up with a deep frown as the Enigma looked over his shoulder

“Pretty rude man.” Eijirou frowned as Mina nodded crossing her arms

Katsuki rolled his eyes.
“You’re all dumb as fuck.” He retorted and shrugged
“There now equal now lemme just ask my damn question!” The blonde grumbled

“Ask away.” Kyouka told him as the others sighed

Katsuki glanced to the side trying to figure out what he wanted to say before speaking.
“Why would an Omega scent someone without asking?”
“Permission?” Denki questioned and Katsuki nodded

“There’s a difference between scenting and marking which is what I assume you’re talking about.” Kyouka said remembering their earlier conversation and smelling the scent that still lingered on Katsuki
The blonde sighed.
“All I know one is more potent than the other.”

They didn’t have much sex education for any gender. It was as important as other things were so if you didn’t ask, find out yourself or experience it yourself you pretty much didn’t know. Which is why Katsuki+
was asking the two Omegas.

“Yeah but scenting can be platonic or like a cute romantic thing. Marking…” Denki glanced to the side

“That’s something very different.” Kyouka finished

“It’s like claiming.” Katsuki said remembering

Denki shrugged.
“Mm. More like putting up a+
sign that says “Don’t touch! This is mine!”

Katsuki frowned confused. Okay so it really was like something more but he still can’t fathom that Izuku would scent him for that purpose.

“Honestly marking is a little archaic. Most people just scent heavily.” Kyouka shrugged
“I’ve only done it once.” Denki nodded in agreement

“So… you’re saying that if an Omega marks someone they’re really staking their claim. That’s not bullshit?” Katsuki questioned and the other two nodded

“Yeah man. It’s basically telling everyone to back off.” Denki told him
“Okay, what’s the purpose though? Just to tell other people to fuck off?” Katsuki narrowed his eyes still confused

Kyouka shook her head.
“No not exactly. Since Omegas don’t do it often it’s not well understood by people who aren’t Omegas, but it’s like a branding.”
“Branding for what?” Katsuki frowned getting annoyed

Kyouka and Denki looked at each other before telling the blonde.
“Mating.” They answered with equal blushes

Katsuki’s eyes went wide along with the rest of the group’s.
“Hah!?” The ash blonde blurted
“Woah seriously?” Eijirou said sounding amazed

“I didn’t know that!” Mina chimed in

Hitoshi smirked looking at his Omega boyfriend.
“Cool. You should mark me more.”

Denki giggled.
“Hito.” He scolded with a little whine
“No. No way in hell did Deku marked me for that.” Katsuki denied

“Is that a bad thing?” Hitoshi question and Denki shook his head

“I mean it’s a little weird to do it that way. Why not just ask but Izuku is a little weird.” Kyouka said

“Bro if he marked you then you should+
just go with the flow.” Eijirou encouraged

“Plus if it really is for mating that means he wants you to fuck him.” Mina giggled mischievously

“Bet he would like to have his cherry popped by his Kacchan.” Denki grinned with a wink as the Enigma’s blood started traveling south
Katsuki shook his head as they entered the cafeteria. He swallowed hard.
“Doubt Deku would want that kind of thing from me or at all. He’s too innocent.”

Denki started laughing.
“Oh poor Enigma. You don’t know how perverted your Omega is.” He said

Katsuki frowned. Izuku was+
definitely not a pervert. They have known each other way longer than anyone else. Katsuki would fucking know if Izuku was a massive pervert. That’s not what got him though. The blonde flushed a little and grabbed Denki, who was still having a laughing fit, by his purple collar.
Hitoshi got it for him for Christmas.

“He’s not- he’s not my Omega. Don’t say that shit!” Katsuki growled

“Just telling the truth.” Denki said and kissed Katsuki’s pink tinted cheek

“There you are Kacchan!” The group, who was trying to separate their two blonde friends before+
the smaller one got killed, heard

Katsuki dropped Denki and Hitoshi caught him as the ash blond looked over to see Izuku approaching them. Fuck he was so cute jogging up to them like that.

“I was looking for you. Can we eat lunch together. I brought you a bento.” Izuku said+
with a smile

Katsuki just started at him with a slight dazed look. Izuku smelled so good. So sweet. Then Mina smacked the back of the Enigmas head which switched him back into gear.

“Huh?” The blonde blinked confused

Izuku furrowed his brows a little.
“I asked if we could+
sit together. I- I made you a bento.” He said holding it out to the blonde

It was neatly wrapped in orange cloth while the bento box itself was black. It was perfect. Omega made them lunch! His Enigma cheered making him let out a happy scent that he tried to quell.

“Uh sure I+
guess.” Katsuki tried to say smoothly as his friends started to giggle and chuckle behind him

The blonde ignored them as he took the bento and Izuku looked so happy about it.
“We can all sit together!” He said and started to walk off

Katsuki didn’t wait anytime. He followed+
Izuku to the table where he was sitting with his friends. Though the blonde could hear his dumb ass friends calling him a simp. Katsuki didn’t care. Izuku made him a bento. When they got to the table Izuku sat down and patted the seat next to him which was on the end. Katsuki+
though it was a little weird that Izuku wanted him to sit on the head but he sat doen beside the smaller anyway. When he opened his bento it was perfect. Spicy tuna sandwiches with cute little sushi roles. Izuku probably made this and it early made Katsuki’s chest rumble with+
content as his scent turned to something more like warm melted chocolate.

Izuku looked over at the taller.
“Do you like it?” He asked

“Yeah. Looks good.” Katsuki said down at Izuku who smiled softly

“I’m glad Kacchan likes my food.” He said and then perked up
“Oh I almost forgot.” Izuku said reaching into his bag that was under the table after he grabbed it

“I have dessert too.” The Omega said handing Katsuki a little baggy that had two blueberry muffins in it

Katsuki wasn’t a huge fan of sweets but there was a few that he liked.
Muffins were one of them. Any type of muffin.

“Thanks.” The blonde said taking the baggy

“Guess I gotta make you katsudon for dinner.” Katsuki said setting the muffins next to his bento

“I wouldn’t mind.” Izuku giggled

“Deal then.” Katsuki gave him a single nod
They all started to eat and the Enigma loved his bento but the muffins. The fucking muffins were out of this world. So sweet and fluffy. Even had strawberry cream cheese in the middle. It’s the best muffin recipe he’s even tasted.

“That looks super good can I try a bite?” Denki+
asked

“Sure.” Katsuki said grabbing the next muffin

“No!” Izuku stood up making the whole table look at him

The Omega laughed awkwardly.
“I just mean there’s plenty back at the dorms. You can have one of those.” He said

“Izuku there’s no reason to be like that. If Katsuki+
is willing to share them let him.” Tenya scolded a little

“Yeah Nerd. No big deal.” Katsuki rolled his eyes as the smaller sat back down

Denki hesitantly took a bit of the muffin Katsuki handed over and the moment he tasted it his eyes went wide. The electric blonde covered+
his mouth as he blushed and Izuku looked down at his lap. The think is Denki knows what’s in the muffin. Slick. The only reason he does know is because one time he and Izuku tasted each other. It was a one time thing and honestly didn’t go further than running a finger through+
the slick and sticking it in their mouths to taste. Putting it in a muffin is so devious. Denki loved the idea. Katsuki was confused as to why Izuku smelled so embarrassed but before he could ask the other blonde spoke up.

“Those are really good! No wonder you like it Kats.” He+
said to the Enigma who looked at him

“Yeah. Best muffin I’ve ever had.” Katsuki nodded finishing off his muffin so he could eat the other

“Thank you.” Izuku said still flushed

Denki looked at the others with a smile.
“When we get back to the dorms you all should try the+
others. They’re super good.” He praised

Hitoshi who was sitting next to his Omega frowned.
“Why don’t we just share that?” He glanced at the muffin Katsuki was picking up with a warning growl

Denki shook his head.
“Can’t. Those are for Kacchan.” He giggled as Izuku nodded+
clearly glad the other Omega was helping him out

Katsuki wolfed down the muffin the cleaned up his area.
“Thanks Nerd. That was really good.” He said scooting the empty lunch box to Izuku

The Omega preened.
“No problem Kacchan I’m glad you liked it.”

(TBC)
The rest of the day was as boring as the first part, but it gave Katsuki some time to think. He had a lot of things to think about like the marking, the sudden clinginess, and the making Katsuki a bento out of no where. It was all odd behavior from the Omega even though they’re+
friends. It’s just not friend behavior, but Katsuki didn’t know what the hell it was. Izuku was nice to everyone. The blonde sighed as he packed his things up then slung his back over his shoulder. As he turned around Izuku was in front of him and he was not willing to admit the+
smaller scared the absolute shit out of him. He nearly screamed.

“Deku what the fuck?!” Katsuki barked to cover the fact he nearly crapped himself

The Omega flinched feeling bad.
“Ah, sorry Kacchan I didn’t mean to scare you.” He apologized and Katsuki huffed air out of his+
nose trying to collect himself

“Did you need something?” The blonde asked

Izuku shook his head.
“No I just thought we were going to walk back to the dorm like we usually do.” He said

“Um unless you don’t want to or planned to walk with someone else.” The smaller glanced down+
at his feet

“I didn’t. C’mon.” Katsuki replied after rolling his eyes

Izuku perked up and trailed after him. As they walked together, because Katsuki slowed down at little so they could walk side by side, he thought about asking Izuku about the marking. He really wants to, but+
what if he asks and Izuku stops. Katsuki doesn’t want that. His Enigma is too greedy for that. It wants Izuku to make mark them. Besides maybe it’s not a bad thing. It’ll fend off other people and their possible confessions that Katsuki keeps getting. The only downside is that+
it’s a little too potent which is actually an upside since that means other people won’t get in his personal space so exactly what was the downside again? Right there was none of course.

“Kacchan, is everything okay?” Izuku asked with a concerned look on his face as he leaned+
forward a bit

Katsuki nodded.
“Yeah. Just thinkin’.” He replied to the Omega

“Oh about the homework?” Izuku questioned

“Uh yeah. We still gotta have movie night with the idiots later so I figured I’d try to get it done before then.” Katsuki said looking over at the smaller
“Right! I forgot the Bakusquad had movie nights on Thursdays.” Izuku giggled

“Yeah. Hopefully it with He another dumbass or boring ass movie.” Katsuki huffed

“Best of luck.” Izuku patted his arm with a cheeky grin

“But it you want we can work together on the homework.” The+
Omega suggested

“Sure.” Katsuki easily agreed

“Okay then!” Izuku smiled

Yeah Katsuki is definitely not going to tell him to stop marking him.

-
-
-
The Enigma went to his room after they made it to the dorms. He needed to change out of his stuffy uniform and into something more comfortable plus he really needed to scent something for Izuku. He decided he would bring it down for the smaller when they were going to do+
homework together in a few minutes. So Katsuki stripped the moment he entered his room and pulled a pair of sweats along with a tank top out of his closet and put them on. Now his next task was to find something for Izuku. He went on the hunt through his close much like he did+
that morning and it took him nearly ten minutes but he finally found something perfect. It was a hoodie that replicated his special ops uniform. It was solid black with a single orange X across the front and lines that circled the bicep area of the long sleeved part.
Katsuki grinned as he slid his closet door shut and walked towards his bed to lay down in his nest and scent the clothing. Scenting items could be done one of two ways. The easy way which was just holding or wearing it so it would get your scent on it. Then there was the more+
caring way which was when you lay down with the item and rub yourself all over it. Katsuki wanted to put more work in since he was giving it to an Omega and his Enigma wouldn’t do anything less. So the plopped onto his nest rubbing the hoodie on his neck first. Honestly he hated+
scenting things in front of other people because of how he liked to do it. He likes doing more in depth scenting. Katsuki liked rolling around like a dog in the grass after a bath on the items he’s scenting. It needed to be perfect especially since it was going to Izuku.
As soon as he finished he realized ten minutes had passed and he popped his head up from his nest.

“Shit!” He blurted just as there was a knock at his door

Katsuki’s head whipped towards and he hopped off his bed nearly stumbling. He assumed it was Izuku since he had taken+
nearly thirty minutes to do all his shit. He totally lost track of time. He got to his door and pushed the handle down then pulled it open to see the adorable prime Omega in front of him. Damn he was wearing a dumb black shirt that said sleep shirt in white kanji. He also had+
some black and white plaid shorts on that would definitely have Tenya saying wasn’t not up to dress code for the common area. They were tight yet not tight enough to catch the outline of anything and they were very short nearly coochie cutters.

“Hi Kacchan. Everything okay?”
Izuku asked pulling Katsuki out of his thoughts

The blondes eyes darted up to see green ones looking back at him with concern so he quickly cleared his throat and glanced away. Damn he can’t get caught starting like a massive pervert. What the hell?!

“Yeah, just had to do+
some. It took a while sorry.” Katsuki replied calming himself and his bowling Enigma at seeing such a sight

“Oh okay. No problem.” Izuku nodded understandingly with a smile

“Um so you want to do the homework together still or…” He tilted his head to the side a little as if+
worried about rejection

“Yeah!” Katsuki said immediately the reeled himself back in

“Uh I mean sure I was just… scenting this for you.” The blonde said holding the hoodie out to Izuku who’s eyes went wide in surprise

“That’s why it took so long.” He added

Izuku smiled+
brightly and took the item immediately pressing it up to his nose right in front of Katsuki who was now wide eyed in shock from the display. Izuku purred, full on purred as he smelled the hoodie. Katsuki just stood there still holding the handle of his door as he wanted and his+
Enigma was going crazy inside his head. It was urging to front, but the blonde wouldn’t allow it which made it whine.

“It’s perfect Kacchan thank you!” Izuku said as he started to put it on

Katsuki flushed a little because Izuku was wearing it not just taking it to put in his+
nest. That was so different and a note intimate thing to do. He doesn’t know how or why prime Omega would do it so carelessly, but at least the oversized hoodie was covering him better. It reached down to his thick tan thighs that Katsuki wanted to drool over.

(TBC)
He couldn’t drool over them he sucked the spit back in his mouth before it escaped too far passed his lips and he glanced away again.

“Yeah whatever.” Katsuki grumbled

“Let’s just go do our homework now.” He added clearing his dry throat again
“Oh why don’t we do it in your room?” Izuku suggested

Yeah let’s do it! Katsuki’s Enigma begged Making the blonde tell it to shut the hell up.

“Deku you know we aren’t supposed to be in each others room. You’re an Omega and I’m an Enigma.” Katsuki said trying to his head+
on straight

“That’s true, but it’s not a big deal. Kacchan and I have known each other forever. It’s not like we’re a couple or something. Plus other people don’t follow that rule.” Izuku argued

Katsuki clenched his jaw. That was a good point. Hell he was going to Denki’s room+
later for the watch party but Izuku in his room. In his den. That’s not a good idea. Something bad might happen. His Enigma was too unpredictable. What if he hurts Izuku or something. He would never forgive himself.

“I don’t know if that’s a good idea Nerd.” Katsuki started
Then suddenly he felt the smaller wrap him in a hug and a sweet flowery smell wafted into his nose.

“Don’t think too much about it Kacchan. I know you wouldn’t hurt me.” Izuku said which Katsuki assumed was because he could smell his anxious scent
He didn’t realize he was starting to smell like charcoal until he was pulled out of his thoughts by the smaller.

“So don’t worry so much.” The Omega told him as he pulled back from the hug and smiled

“Kacchan‘s a good Enigma~.” Izuku purred

Katsuki jolted his arm swinging the+
door all the way open to let Izuku in. Enigma, he called us Enigma. We’re his good Enigma. Omega approves! Katsuki could hear his stupid hind brain chant. Izuku happily pranced in the room as Katsuki blinked confused until he glanced over his shoulder to see the Omega looking+
around his room. Did he just call him Enigma to get his way? What the fuck? More importantly why the hell was Katsuki so weak to it? Because he’s out Omega! His Enigma supplied only making the blonde frown as he left his door cracked. There was an Omega in his room and he was+
not going to make him feel trapped even if he walked in on his own.

“Oh you hasn’t used the scented clothes. Is there something wrong?” Izuku asked looking over at Katsuki who had just turned to face him

The blonde glanced to the side. It was hard to look at the Prime Omega+
dressed in his colors.

Katsuki shook his head.
“Just haven’t had time to incorporate them into my nest.” He said

Izuku nodded understandingly and looked over at the other’s bed.
“Kacchan has a big nest. It’s sugoi.” He complimented walking towards it

Katsuki blushed a little+
at the praise.
“Tch- course it is. I’m the best at everything even buildin’ a nest.” He huffed feigning being cocky

It was actually a huge compliment if an Omega said your nesting skills were good.

Izuku giggled.
“Right. Should have known.” He said

Katsuki felt uneasy, but+
decided to distract himself by getting his books and a notebook to work on their stuff.

“Kacchan I really like your nest. It looks so cozy and it’s big enough for more than one person.” Izuku said making Katsuki look over at him to see he was lighting running his fingers along+
the top of the six inch tall wall made out of clothing

Katsuki was at his desk holding a mathbook and pencil as he watched the Omega caress his nest. Something primal started to tug at him. He shook his head immediately to make it go away.

Izuku then laughed.
“Mine’s only big+
enough for me and it would be cramped if I had someone else in it.” He started to go off on a tangent

Katsuki looked back at the items he was gathering.
“Well unmated Omegas should only have people they trust in their nest otherwise it could be dangerous.” He said
Izuku grinned looking over at the blonde
“I’ve never had anyone in my nest other than mom but that’s been a long time.” He stated

“I would let Kacchan in my nest though.” The Omega stated walking towards him

Katsuki frowned.
“I wouldn’t do that. I’m too big for one and two+
that’s your nest. I shouldn’t be in it even if you wanted me to.”

Izuku frowned now.
“Why?”

Katsuki looked over at him setting his pile of materials down on the desk.
“Because Deku you’re an unmated Omega. It’s not right for me to be in your nest.”

Izuku stared for a moment+
then giggled.
“Kacchan’s so old fashioned.”

Katsuki scoffed.
“Shuddup. It’s called being respectful idiot which you don’t seem to understand since you waltzed right into my den without permission.” He told him

“Well if Kacchan really minded me being in here he would have told+
me to leave.” Izuku fired back

Katsuki growled.
“I’m only allowing you in here cause I trust you.” He grumbled and Izuku smiled

“I’m glad.” He replied

“Let’s get to work. Hold these, I’ll get the Chabudai.” Katsuki said handing the prime Omega the books and other utensils
Izuku happily took them then went to stand near the bed while Katsuki got out the short legged table and set it up. He snatched two pillows from his nest and plopped them on the floor as Izuku laid out the materials they needed to do their homework. Katsuki sat down first and+
Izuku moved the pillow so he could sit right next to the blonde. He tried not to tense to let his smell shift. In a day or two his pre rut symptoms will get worse, but if he keep simping too hard he might go into an early rut. Katsuki tried to just focus on their homework and he+
and Izuku collaborated to finish it.

“We finished it pretty quickly.” Izuku said happily and the other nodded as he closed his books

“Fucking finally. I hate homework.” Katsuki grumbled making the smaller laugh

“It’s not all bad Kacchan. You gotta learn things somehow.” Izuku+
said moving to stand on his knees then lean over the table with his elbows support him while he looked out of Katsuki’s glass balcony door

That gave the blonde a perfect view of his ass if he looked a little to the right which he did. Izuku butt was literally inches away just+
begging to be touched by warm hands. So Katsuki lifted a palm moving it forward to touch but paused just as it was almost touching. It wasn’t a good idea. He thought as his hand hovered over Izuku ass. Katsuki jerked his hand away when the other moved to sit seiza on the pillow.
“Thanks for letting me work with you Kacchan?” Izuku smiled but Katsuki wasn’t looking at him

“Yeah. No big deal. I should get going. Got that thing with the idiots.” Katsuki rolled his eyes

(TBC) Follow and like for more content! RTs/QRTs are appreciated! Hope you’re enjoying!
I’m sorry this took me so long to update. I’ve been procrastinating 😭. Aways here we go!
“Right. Are you still planning to get scented items from them.” Izuku asked with a small tilt of his head

Katsuki nodded getting up so he could put his things back on his desk.
“Yeah. Figured they would just give them to me when I show up.” He said walking away from the smaller
“Well good luck with that. I gotta get going too. I think Tenya, Ochako, Tsu, Shouto, and Hitoshi all want to play a board game.” Izuku replied standing up from the Chabudai

“Tch- more like bored game.” Katsuki said after setting his books on his desk

Izuku rolled his eyes.
“Haha so funny Kacchan.” He said then giggled when he got a glare at his back talk

“Shuddup Nerd. Don’t act like y’all aren’t gonna play D&D like a bunch of dweebs. That’s boring with a capital nerd!” Katsuki scoffed putting the papers in his bag that was sitting on his desk+
then turning around

Izuku was right there in front of him reaching forward to hug Katsuki as he turned around. The smaller’s arms wrapped around his waist and squeezed. If he keeps doing that Katsuki might actually loose it either from being scared out of his skin or the potent+
unmated Omega smell. He swears Izuku is making it more prominent. The little prime has to be.

“Well it’s not like Kacchan has to go. So don’t be like that.” Izuku said pressing his ear the other’s heart

Oh. Izuku must just be worried about him. After the war when Izuku would+
be worried about Katsuki he would just lay his head on the other’s chest and listen. It was to make sure he was alive, safe, with Izuku. Katsuki actually didn’t mind the contact. He felt remorseful and yearned for the same touch himself. He was always worried or doing things for+
Izuku. Right now though it was clear Izuku was scenting him.

Katsuki pulled away a little as he grabbed Izuku by his waist to keep them separated.
“Just teasing Nerd.” He said

“Kacchan’s so mean.” Izuku pouted

Katsuki snorted.
“Go have fun with the dweeb squad.”
Izuku rolled his pretty eyes.
“Have fun with the bandit brigade.” He retorted heading to the door since it was clear the blonde wanted him to leave

The blonde chuckled.
“I will.” He said

“So will I.” Izuku said back as he walked backwards out of the room

“Tch- stupid cute+
Omega.” Katsuki muttered as he rushed to put the rest of his stuff away

He liked a clean room. Eventually Katsuki made his way to Denki’s room where they were the Omegas were making a nest on the floor as the Alphas and Betas helped. Katsuki joined and when they were finished+
they snuggled together with a large weighted blanket over them while they laid together in many pillows that were used as the base of the nest. It was comfortable and one of Katsuki’s favorite things to do with his pack whether he admits it or not. Apparently Izuku’s scenting+
this time wasn’t as strong since no one complained or wanted to get away from him. Brining it up must have made the prime Omega realize what he did so he lessened it a bit. The others still noted that he smelled like Izuku though and honestly Katsuki liked that he did.
After the Movie was over everyone started to get up and pick up the nest. They piled it into many baskets then gave them to Katsuki so he had more materials scented by his pack for his nest. Katsuki along with Sero and Kirishima hauled them up to his room. Katsuki started+
cleaning up his olde nest to remake it with the new scented clothes much like an Omega would no except a few sizes bigger which is why he was given so many clothes. He decided to save Izuku’s clothes last so they would be closer to the top. However, Eijirou and Hanta didn’t+
know that and spotted him an extra basket in his room so while Katsuki was taking apart the old nest Hanta walked towards it. As a Beta, the raven haired guy had a hard time with smells, but he could smell the difference between alphas of any kind and Omegas. Especially if their+
scents were really strong like Katsuki’s. Eijirou could smell the scent wafting off of the basket of clothes next to Katsuki’s desk and decided to warn Hanta.

“Dude don’t.” He whispered hoping Katsuki wouldn’t hear them since he’s deep in nest planning

“What why?” Hanta asked+
as the Alpha let go of his arm

“Cause bro. Those are definitely Izuku’s clothes. I’m pretty sure Kats will rip your throat out if you touch them.” Eijirou told him

Hanta looked at the clothes he was near.
“Izuku gave him clothes? I didn’t know he did that.”

“He and Katsuki+
definitely have a thing going on. Just not sure what.” Eijirou murmured

Hanta frowned looking towards Katsuki and seeing him rebuild his nest. The more he thought the closer he was coming to a conclusion that made him gasp. He jolted in surprise and placed his hands on the+
shoulders of the buff Alpha next to him.

Eijirou looked at him confused until the raven haired Beta spoke.
“What if Izuku is courting Katsuki?” Hanta said and the red head scrunched his face confused

Eijirou shook his head.
“No way. Only Alphas and Enigmas do that.” He told him
“Dude don’t be so old fashioned. Some Omegas do it now. Plus think about it? The scenting, the clothes, the food. I mean isn’t that what you guys do when you’re courting? Sometimes at least.” Hanta said making a really good point

Eijirou gasped.
“Holy shit man!” He said in shock
“What?” Katsuki looked over at them after being pulled from his planning

The Beta and Alpha whipped their heads towards him and immediately waved their hands.
“Uh nothing bro” Eijirou told him

“Yeah don’t worry about it.” Hanta laughed awkwardly

Katsuki narrowed his eyes, but+
looked back at what he was doing. He typically doesn’t let others watch him make his nest, but it was okay for his pack to see.

“You two morons can leave now you know.” He said

“Right. Sorry for overstaying.” Eijirou nodded turning to head for the door

“If you need us man you+
know where we are.” Hanta added and they left promptly

Katsuki rolled his eyes.
“Like I want you two to help me with my best. You’d fuck it all up.” He muttered as he finished the base

Outside in the hallway Hanta and Eijirou looked at each other with wide eyes.
“Should we+
tell the others?” The lanky guy asked

“Do you think he knows?” Eijirou questioned at the same time

“No.” Hanta said answering the redhead first

“Yes.” Eijirou nodded answering the others question then they nodded once and started down the hallway towards the elevator

(TBC)
Not me procrastinating. Sorry this took so long again 😭.

CW/TW: Masturbating

I feel like I should put a foreskin warning 😂. Bakugou’s uncut.
Katsuki was nearly done with putting his new nest together so for the finishing touches in he decided to top it all off with Izuku’s clothes. The blonde walked towards the basket sniffing the air and smelling a potent unmated Omega. As usual it was a blooming forest smell like a+
sweet spring day. Katsuki couldn’t help but grab a shirt of the top and hesitantly press it to his nose. Honestly he felt a little perverted doing such a primal thing but it had to be okay right? Izuku knew he would do this. It’s not weird, he’s just smelling the sweet scent.
The taller’s chest rumbled after he closed his eyes unintentionally while he continued to take in the pheromones. His own aroma melted into a warm chocolate scent since he felt so content. After a few minutes his eyes opened and it was like he was in a trance.
“Omega.” He mumbled then used the clothes in the laundry make to finish his nest

He went to grab the last clothing item absentmindedly until he held it up and realized what it was. Katsuki’s brain froze then restarted as his face heated up. Panties. In his hand that was about+
to detonate out of embarrassment were a pair of plain black panties. They were fancy or even lingerie. Just regular every day panties but fuck did Katsuki and Enigma not even care. They were an Omega’s panties, a prime Omega, and they smell so fucking good! Too fucking good and+
extra sweet like honey. Katsuki couldn’t control himself as he pressed the panties to his nose like some feral perverted Enigma. His nose hit the crotch area and his dicks twitched. He couldn’t fucking keep it together. He climbed into his next after pulling his pants down a+
little. After shoving down his boxers he saw both of his cocks were nearly full chub. They throbbed and twitched with interest.

“Deku.” Katsuki growled breathily as he moved the panties to his cocks

He made sure the crotch area where Izuku’s pussy probably pressed against+
while he wore them was right on his dick heads. With his free hand his grabbed the lube from his beside drawer. He quickly opened it with his teeth and dribbled it over the panties then down his shaft. He closed the bottle and tossed it to the side as he felt the cold substance+
soak the underwear. Katsuki imagine it was Izuku’s sweet tasting slick that darkened the already black underwear. The blonde’s Enigma reared it’s head making him drool a little when he started to stroke himself. His cocks were covered a little by the plain underwear but it+
didn’t matter. They smelled so strong and it was making his head fuzzy. His foreskin under the panties retracted then moved up sheathing his precum dribbling heads with each pump of his hand. Having both dicks pressed together helped with the need of friction.

“Omega… ‘Zuku…+
P- Prime mm Omega…” Katsuki murmured as he moved to lay back

The thought of Izuku bouncing on top of him made his knots start to swell. He whined almost pathetically as he stilled his hand and thrusted up into it smearing precum all over the inside of Izuku’s panties.
It was too good. Being surrounded by things that mostly smelled like the Omega and fucking into his underwear, it was a dream come true. A dream he only realized recently however being in this deep probably meant something like that was always there. Katsuki’s eyes went wide as+
he slid his hand all the way down to squeeze around his thick knots and that was it. They popped shooting coats and coats of virile cum into the black panties. The blonde panted tasting blood from his lips. Just as he came his long sharp Enigma canines protracted from their+
usual length and nicked his bottom lip. He knows why though. They protruded because he wanted to claim Izuku. It was the only thought he had just before blowing his load into the now completely soiled underwear. Katsuki jolted as post nut clarity set in and he sat up with a+
small moan. His cocks were still cumming, but he didn’t want to make a mess of his new nest so he struggled to get up. Katsuki shivered as he stood pressing the underwear to his cocks trying to keep as much of his cum from dripping out as he could. The walk to his bathroom was a+
nightmare but when he got there he plopped the cum drenched underwear into the sink and pressed a hand to the wall as he watched the rest of his release taint the toilet water. His hips jerked a few times before he was finally done. Katsuki sighed, wiping his brow and flushed+
his spent down the toilet. His Enigma whined about wasting so much cum like it did everytime he jerked off. The stupid thing wants him to pump a womb full which he won’t be doing anytime soon. Katsuki can’t raise a kid at eight teen. The blonde looked at the cum covered panties+
and honestly felt a little guilty about what he did. Izuku would definitely feel uncomfortable if he knew he soiled the underwear thinking about fucking him into oblivion. Katsuki scrubbed a hand over his face then went to get some new clothes on and go to bed. He can deal with+
washing and returning Izuku’s panties tomorrow. He hopes the smaller won’t smell his spunk on them. After slipping on some sweats he passed out in his nest forgetting to eat dinner.

(TBC) Follow and like for more content! RTs/QRTs are appreciated! Hope you’re enjoying!
The next morning he woke up early and groggy as usual. With a grumble he got out of bed and started his morning routines. Though he hates getting up early he always did. After showering he took his dirty clothes to the laundry room along with making sure Izuku panties were in+
there so they would be washed. He did his morning work out then ate breakfast and got dressed for school. It was the last day before the weekend. Katsuki also made sure to keep himself in check by taking some suppressants. As an Enigma his rut can show up full force randomly or+
his pre-rut can make things pretty difficult. It would be like fighting his instincts that were sending him into rut and that was frustrating to deal with. Taking suppressants can make things easier and keep his instincts at bay. After than he went to get his clothes from the+
dryer in the laundry room. As he was taking them out Ochako stepped in right as he was putting Izuku’s underwear in his basket. They made eye contact and suddenly more shame filled him. He knew what this would look like to an Omega so he quickly dropped them and stood up.
“First it’s not what it looks like. Second Izuku gave them to me.” Katsuki said then realized maybe he shouldn’t have told her that

Ochako had a weird look wash over her then she shrugged.
“Not any of my business what you two nerds do.” She giggled and walked towards a+
washer and dryer

Katsuki frowned.
“Not gonna like accuse me of anything?”

Ochako started putting her laundry that smelled like warm honey oatmeal in the washer.
“Do you want me to accuse you of stealing Deku’s underwear?”

Katsuki’s ears flushed.
“No! I wouldn’t do that shit!”+
He growled, but she wasn’t threatened

Ochako finished her task and turned to him.
“I know which is why I’m not really surprised. It’s more believable that Deku gave them to you than you sneaking into his room and stealing them. That’s more like Minoru.” She said and Katsuki had+
to agree

“Don’t think he meant to give ‘em to me. They were just in the scented laundry he gave me.” Katsuki said

Okay so normally he wouldn’t divulge this much information to someone, but he and Ochako are sort of kind of friends adjacent. The Omega seems to understand him+
in many ways more than other people and sometimes even his own friends. Katsuki never understood why. Especially after it seemed like she wanted him and Izuku to fix their relationship issues. The blonde knew Ochako liked Izuku. It was obvious as the fucking Sun in the sky yet+
she always tried to get them to talk it out or at least seemed to be concerned about them. It was kind of nice that someone was rooting for them and now they he and Izuku are as good as gold she still pushes them to stay friends if things get rocky. Katsuki did feel sort of bad+
when he heard Ochako confessed and got rejected by Izuku. Of course the smaller let her down easy. They were still friends and she was friends with Katsuki too. Some would call it a miracle. Katsuki would call it annoyingly nice to have her company. The way Ochako was looking at+
him made her even more irritating though.

“What?” Katsuki frowned

Ochako shrugged.
“Maybe he meant to.”

Katsuki snorted.
“Nah. I’m sure it was an accident.”

Ochako rolled her eyes.
“Yeah, giving an Enigma he spends a lot of time with some scented panties is definitely+
accidental.” She said with sarcasm

Katsuki narrowed his eyes.
“You implyin’ somethin’?”

Ochako crossed her arms.
“I’m just saying that most Omega’s wouldn’t be so careless as to give someone an intimate item. I mean Deku’s given other people scented clothes. Do you think he+
give them his underwear too?”

That… Katsuki didn’t like that. An ugly possessive feeling that has festered inside him for years started to bubble up. His Enigma hated the thought of Izuku giving his panties to someone that wasn’t him. No way would he do that, but then why did+
he give them to Katsuki? If it was an accident then sure, but Ochako was right. Even Izuku wouldn’t be so careless. So maybe he did give something like that to other people. Did it mean nothing to Izuku?

“Maybe use your upstairs brain instead of your downstairs person.” Ochako+
glanced at the underwear on top of Katsuki’s clothes

“I’m sure last night there wasn’t much use of your upstairs brain.” She giggled

Katsuki immediately frowned feeling flustered and slightly ashamed.
“Tch- didn’t do shit.” He huffed picking up his basket of clothes
Ochako rolled her eyes.
“Sure. They just happened to be the only item of clothes of Deku’s that needed cleaning this morning.” She said yet again sarcastically

“Shuddup! This conversation never happened!” Katsuki barked and stomped out of the room leaving Ochako laughing
The blonde huffed and made his way back upstairs to put his clothes in his room. He needed to grab his bag before he left anyways. When he got to his hallway he spotted Izuku standing at his door with his hand raised to knock.

“Nerd.” Katsuki said making Izuku jolt then look+
his way

The smaller smiled.
“Good morning Kacchan!” He chirped as Katsuki walked towards him

“The hell are you doing on my floor?” Katsuki asked setting his clothes down to open his door when Izuku stepped out of the way

“I just thought we could walk to school together.” The+
smaller answered cheerfully

“Don’t we always do that?” Katsuki questioned picking up his clothes and stepping into his room

“Well yeah, but usually with our friend group.” Izuku said walking into Katsuki’s den like he owned the place

Katsuki placed his basket of clothes near+
his closet.
“So you wanna what? Head to school together alone?” He asked as he grabbed his bag from beside his desk

Izuku nodded.
“If you don’t mind. I actually needed to talk to you about something. I rather do it alone…” He glanced to the side seeing his panties on top of+
Katsuki clothes

The blonde shrugged his bag on his shoulder.
“Fine I guess.” He said looking at Izuku the at what he was staring at

His face flushed. He was so pissed at Ochako for teasing him that he forgot about the panties. Fuck Izuku’s going to think he did something weird+
to them. Well technically he did but Izuku didn’t need to know!

“Are these my underwear?” Izuku said stepping towards the basket to pick them up

Katsuki gulped. No use in lying now.
“Uh yeah. Think you accidentally gave them to me with your other clothes. I used all the others+
for my though so thanks.”

Izuku flushed and his scent turned a little sour which was odd.
“I’m so sorry Kacchan. I’ll take these back. Can I use your bathroom for a moment?”

Katsuki frowned. Izuku didn’t even try to accuse him of anything and the request was weird.
“Sure.” He+
shrugged awkwardly

“Thanks I’ll be quick then we can go.” Izuku said walking towards Katsuki bathroom in his door as the other blinked in confusion

(TBC)

Back to the top⤴️
Katsuki just stood by his door waiting silently for the Omega. The underwear thing obviously wasn’t a big deal since it was sort of clear Izuku hadn’t meant to leave the panties in the basket. That was sort of a relief even though he still thinks it’s weird. Why would Ochako say+
that if Izuku actually left the panties there on accident? This is too confusing. Katsuki shook his head. It doesn’t matter now. He’ll take his secret to his grave and move on with his life. Just then Izuku opened the bathroom door and stepped out shutting it behind him.
“Okay we can go now sorry. I had to put up my um… you know and I had to pee.” Izuku informed

Katsuki rolled his eyes trying to act casual in the uncomfortable atmosphere.
“It’s fine. Let’s go before we’re late.“ He opened his door and walked out expecting the other to follow
“Okay!” Ixuku of course trailed after him

“Hurry it up. I ain’t listening to class prez lecture for being late cause of you.” Katsuki barked

“I’m right behind you Kacchan. I know.” Izuku whined as they made it to the elevator

-
-
-
“What’d you wanna talk about?” Katsuki asked looking over at the shorter next to him

“Oh right.” Izuku scratched his cheek as they walked side by side on the sidewalk to school

Katsuki stayed quiet letting the other find the right words.

“So there’s this Alpha in the support+
course that keeps hitting on me. I’m pretty sure he wants to court me, but I’m… not really interested.” Izuku said looking at his feet

Katsuki’s nostrils fared, but he kept himself from letting out a threatening growl.
“Then reject him.”

“I don’t know. Maybe the experience+
could be good. I’ve never dated anyone let alone been courted. It would be sort of embarrassing to be a completely knew to everything.” Izuku started to ramble

“Plus maybe if I like him a lot then I could you know spend my heat with him. Having to do it alone is pretty tiring+
and unsatisfactory.” He added with a small blush

Katsuki’s eye twitched as he was so close to snapping. His Enigma was practicality ramming it’s head against the side of Katsuki’s four head trying to get out. He hates this. Izuku spending his first heat with someone and it’s+
not going to be him? No. No. Hard fucking no. Katsuki won’t allow it. He can’t. That asshole probably won’t even know what to do or where to put it.

Izuku didn’t know of the blonde’s inteormoil because he continued on his rant.
“So I don’t think it would be a big deal to have+
my heat with him.”

The smaller shrugged.
“He’s nice looking so I’m sure it would be satisfying.” Izuku said then smiled sheepishly

“I could even present for the first time. I’ve never done-“ He started but got cut off as the taller stopped abruptly

“No!” Katsuki looked down+
at the Omega who jolted then his eyes shifted up to the others

“No?” Izuku questioned with a tilt of his head

Katsuki swallowed hard. He shouldn’t have yelled. The blonde felt guilty for doing so. Why the hell did he have to be so possessive over someone that’s not even his.
“No. Just reject him.” He tried to say in a calmer tone

Izuku blinked then glanced to the side.
“Well he might want something casual and I would be okay with that. Like I said it could be good for experience.”

Katsuki frowned.
“You wanna have casual sex?” He asked
Izuku blushed.
“M- maybe. I mean I don’t really want to date him. I would be upfront about it of course.” He replied then giggled sweetly

“Besides it’s not like I have anyone else willing to have um casual sex with or even court me.” Izuku looked back up at the blonde
Katsuki could do it. He was so do it. No way would some extra satisfy Izuku like he could. He’s got two dicks, twice the knots, and he was fucking big. He’s everything an Omega would want down there. Why wouldn’t, why hasn’t, why didn’t Izuku ask him instead. Right because he+
was an idiot.

“So what you’ll just mess around with some stranger like a corner wh-“ Katsuki stopped himself before he could finish his sentence but it was too late

Izuku was glaring at him.
“Finish your sentence Kacchan, like a corner what?”

Katsuki looked away swallowing+
hard. Izuku was angry. His scent smelled like a burning forest. It almost made Katsuki tilted his head to the side showing his scent gland in submission. No one could get him to do that. No one but Izuku. He closed his eyes and tried to dig himself out of this situation.
“I- I was gonna say like some corner whore, but I shouldn’t have. It’s none of my business what you do Deku. I’m sorry.” Katsuki bowed his head

He did feel bad. The blonde isn’t the type to use that kind of language at all yet with Izuku it just spilled out of his dumb mouth.
He’s horrible as usual.

Izuku crossed his arms glancing to the side.
“You’re right. It’s not any of your business what I do especially when it comes to my body and who I date.” He said as he eyes looked back at the blonde who nodded in agreement

“Is there a reason you’re so+
against it? Is it because I’m an Omega and I’ll be tainted if I don’t save myself for a mating?” Izuku frowned

Katsuki grimaced. A lot of older Alphas have that might set that if an Omega sleeps with someone they’re not mated with before they ever mate then their purity is gone.
“No Deku you know I don’t think like that.” He said

Izuku clenched his fists at his sides.
“Then tell me why you care who I sleep with!” He rose his voice unexpectedly making the other jolt

“Because I don’t want you to get hurt!” Katsuki blurted then his eyes went wide and he+
looked away

Honestly he wasn’t expecting his mouth to say that, but it was half true. The other half was Katsuki being jealous. He wanted to be Izuku’s first and he wanted Izuku to be his first. Was that so bad? Maybe it was. Especially if he just upsets Izuku in the process.
“What?” Izuku asked quietly

“You’re smart nerd but you’re also dense. I just don’t want someone to use you and leave you when you really like them.” Katsuki said trying to keep an even voice

“You deserve more than that. You deserve someone who will properly court you and do+
all the sappy things you want to do. Not just fuck and forget it, you know?” He said because he wanted to be that person

“Then why didn’t you say that? Why did you have to say something so mean?” Izuku asked

“I’m still shitty at sayin’ things right. Wasn’t trying to hurt your+
feelings.” Katsuki rubbed the back of his neck

“I forgive you but next time just talk to me okay? It doesn’t have to be a big deal.” Izuku said hugging the blonde who tensed for a moment

“Yeah. I will.” Katsuki said hugging him back

“I’ll reject that guy anyway. I feel like+
letting it go further would be playing with his feelings.” Izuku told him

Katsuki nodded feeling his Enigma cheer.
“It’s your choice Nerd.” He said as the other looked up at him

“I know. Not even Kacchan can tell me what to do.” Izuku giggled and booped the taller’s nose

(TBC)
Eventually the two made it to the classroom, but when it was lunch time Katsuki followed Izuku who seemed to be sneaking off and not going to lunch with their friends. Katsuki reigned in his scent as he peeled around the corner to see Izuku talking to some Alpha.
It must be the one he had been talking about earlier. The guy wasn’t bad looking but something seemed off. He just gave Katsuki bad vibes. Then when it looked like they were arguing Katsuki felt anger rush through him. How dare that Alpha tell at his Omega. Damnit no. Not his+
Omega! Katsuki retorted. The blonde glared in the two’s direction as he watched like a voyeur. Izuku seemed to be holding his own then he started to walk away only for the guy to say something and grab a hand full of Izuku’s ass. Before Katsuki could even do anything Izuku+
whirled around and scratched the offending Alpha across the cheek making him yelp. Katsuki’s white hot rage simmered to a strange sense of pride. Of course Izuku didn’t need him he was a strong Omega all by himself. He could fucking fold any Alpha no matter how big or strong.
Katsuki’s chest almost rumbled until he realized Izuku was walking his way. Katsuki quickly tucked himself between the water fountain and the wall that was in a little alcove a few feet from where he had been standing. He heard the smaller’s steps getting closer then he held his+
breath when Izuku walked right passed him as if he wasn’t even there. He was almost in the clear until the prime Omega stopped in his tracks a little passed the alcove where the water fountains were.

“Kacchan?” Izuku said quietly sniffing the air

Okay maybe if Katsuki+
literally doesn’t move a muscle Izuku will just keep walking and never look over his shoulder. It was wishful thinking because a moment later even though he had been deathly silent Izuku turned around looking right at him. Seeing the large blonde squished in the small space near+
the water fountain and the wall must have been funny because Izuku started laughing. Katsuki frowned and slipped out almost falling but caught himself as he grunted in annoyance.

“It ain’t funny, Dweeb.” The blonde told him

“It’s very funny Kacchan. What are you even doing+
here?” Izuku asked wiping a happy tear from the corner of his eye

Katsuki huffed crossing his arms.
“Nothin’.”

Izuku looked as him fondly.
“C’mon I know you followed me. I could smell you the whole time.”

Katsuki frowned at being called out. Damn he thought he was sneakier+
than that. The blonde shoved his hands in his pockets feeling his All Might card touch his right hand.
“Fine. I followed you to make sure you were gonna be okay.”

“Huh?” Izuku tilted his head

“I figured you were gonna reject that guy or whatever so I came to make sure he+
didn’t try anything.” Katsuki told him

“I can take care of myself Kacchan.” Izuku retorted

“Tch- I know that but I just felt like I should alright?” Katsuki shrugged

“Guess your instincts were right. He wasn’t very nice and he did want to use me.” Izuku admitted, rubbing his+
upper arm

Katsuki stepped forward.
“You okay?” He asked

Izuku nodded.
“Yeah.”

Katsuki looked the other up and down since he started to smell Izuku’s sour scent.
“You sure I mean he-“

Izuku nodded.
“I know… but it’s not like that’s the first time.” He rolled his eyes
Katsuki frowned.
“Doesn’t mean you gotta be okay with it Deku. You should go kick him in the dick.” He said

Izuku shook his head.
“I can’t do that Kacchan.”

Katsuki scoffed.
“Well I can. I’ll do it right now.” He turned to walk off only to be stopped

“No!” Izuku blurted+
latching onto the blonde’s arm

Katsuki felt smaller ones wrap around his large taut with muscle arm as he looked down to see Izuku looking up at him while leaning his head on the blonde’s his bicep.

“Just come to lunch with me.” Izuku with those puppy dog eyes that could make+
even the worst of the worst bend the knee

“Alright.” Katsuki said conceding as he smelled Izuku normal sweet scent

They headed to lunch and sat with their friends as usual. Of course they asked where they were and Izuku told them he had yo reject an Alpha’s advances. When he+
told them guy groped him the others were pretty mad and rightfully so especially the Omegas in their group. Izuku told them it was okay because Katsuki was there if things got to far. When he was asked why he had followed Izuku he replied that he had a gut feeling something+
might go wrong and it did. Again it wasn’t really a lie it was just only a half truth. Eijirou and Mina seemed to understand that because they looked at him pointedly to which he ignored. After lunch they all returned to class but once that was over Izuku asked if they could+
train after dinner. Katsuki agree then they went back to the dorms. When he got to his room he could smell so much of Izuku’s scent. It made his chest rumble as he walked towards his large nest. God he loved Izuku’s smell. He wished he could smell it from the source. Just grab+
the Omega and push his nose into that sweet scent gland at his neck. Damnit he was getting hard again as he started to get undressed near his bed. His Enigma was begging him to ask Izuku to join him for his rut but there’s no way that could happen. It was too risky as much as he+
secretly wanted it. Katsuki sighed and walked towards his bathroom after taking off all his clothes. He could just get it out of his system in there rather than making a mess of his bed and nest. When he entered the bathroom he was hit with a delicious scent that nearly brought+
him to his knees. It was as sweet as honey or nectar. What the hell was the smell? Katsuki though as he shut the bathroom door behind him. His cock throbbed when he spotted something on his closed toilet seat. A pair of panties. They were orange. Who the hell left those there?
Then it donned on him. Izuku used his bathroom before they left for school. He… left them there? It had to be in purpose right? They didn’t even smell like the other ones that were scented. What was on them? Before Katsuki knew what he was doing the panties touched his nose.
His cocks throbbed hard making him groan. Slick. It had to be slick. Izuku cunt or ass left slick his these panties and he left them there for Katsuki to find. There’s no other explanation right? Izuku did it in purpose. He had to have. His Enigma clouded his mind and he sat on+
the seat, sniffing the orange panties. He started jerking off to the thought of Izuku standing naked in front of him. He’s been hard before, but never like this. Izuku’s scent was so good.

Title: Pickup.

Bakugou pulled up to his new house in his red pick up truck. It was a gift from his mother and father who got it for him since he broke the top ten along with Midoriya.
They were a duo after all. The blonde was excited to move into his new home. Midoriya was next to him in the truck vibrating with just as much enthusiasm. Bakugou invited Midoriya and not his other friends because he actually planned to ask the smaller to move+
