#mobrei omegaverse where it starts has both of them being alpha.
But because Reigen keeps saying that Mob obviously cannot be with him because they both are, Mob decide to bitch him. if he can't have alpha Reigen, surely he can have omega reigen right?
wonder how Reigen would react when he finally starts to catch up on what Mob is doing to him.
Yet it's already too late when he does, because his body has already started to change and shift 🤭
also now Mob only created a new source of worry for himself because even tho Reigen is becoming an omega, he still looks like, talks like and acts like an alpha (after all, he's been one for so long) and this only triggers other alpha who can't believe an omega would act like this with them
Y'all think Reigen would be in denial at first when he starts figuring out what Mob is doing 🤔? Like, Mob couldn't /possibly/ be doing something like this, right? But now that he has suspicions it is pretty hard to ignore all the things Mob does to him and
if he tries to fight back just a little bit Mob gets really domineering in a way he's never really seen him do so (since when is he able to do that?!? Where did small and cute lill' mobbu go?!?)
Then I wonder if he would just, accept it. He decides it's not worth fighting against Mob for it, not that he would ever win anyway, even less with how much he's already changed anyway. Plus, who would want a bitched alpha? He's pretty sure that aside from Mob, no one else would want him.
and maybe a lill' voice in his mind nag him about being happy about it, because now there isn't really any reason he cannot be with Mob (aside from like, the age gap, but they are adults now so...)
Reigen had been feeling kind of off lately. It felt like pre-heat symptoms at times, yet he knew it shouldn't be happening right now, he still easily had a bit more than two weeks to go. Even if it were to come in a little bit early wouldn't be NOW.
He was pretty thankful that the day had been rather slow, he had even sent Serizawa home earlier, feeling somewhat uncomfortable around him all day anyway.
He was finishing up some paperwork despite how late it was compared to the usual.
But he wasn't feeling right yet and the idea of getting overwhelmed by sound and smells once again wasn't appealing.
Plus, he did have some paperwork and thing he had been neglecting.
Yet his focus was taken away immediately when he realised with horror that he was, in fact, starting to be in heat.
Yet he shouldn't be!! He had been taking his suppressant and blocker like usual, not missing once!
And has minutes passed by, it only got worse and worse, nothing like what he would usually go through. Hell, nothing like he had really felt in his life before.
He could felt weak, hot all over and his slacks were totally getting ruined by his slick. Had he always produced so much of it before? It felt excessive for an omega his age.
He groaned as he tried getting up, there was no way he would be able to g back home tonight, not like this at least. He would just lock the door, sleep on the couch and call everyone tomorrow to say he would close for the day.
Yet he couldn't do any of this, body freezing when he caught a strong scent suddenly coming and mixing with his own sweet scent.
He cringed a little at the way his inner omega sang at the sight of Mob, an alpha he was attached to, that both he and his deeper instinct trusted with his life. As much as he trusted Mob, he could see the way he was already being affected by this.
His body want to stand her meekly and wait for the alpha to come and take care of him, especially since it was someone Reigen already trusted so much. Yet he willed his body to try and go the to exorcism (massage) room, his body sluggish and slow.
But before he knew it, he heard the familiar sound of the lock clicking, then he was being pushed onto his desk, action surprisingly gentle despite how much force Mob was using to keep him pinned under him.
He saw the way Mob was breathing hard, nostrils flaring a little as he took in more of his scent, now worse and reacting to an alpha being over him like this. He could see the way his pupils where so dilated, barely leaving a tight ring of brown around it.
His breath hitched when Mob pressed his already throbbing cock between his leg, rubbing against the drenched and soaked in pants, only messing up Mob's own school uniform..
"Wait, Mob" he tried to stop him when he felt hands on his belt, hands weakly trying to push away. "Mob, stop it, you're not in your right mind" he tried to warn him, biting back a whine when the young man pushed a hand down his pants, finger teasing his soaked entrance.
He tried wiggling out from under the young man as he pulled his slacks off of him, nearly falling off of the desk and he climbed higher on it.
He had been ready to fall head first onto the ground, yet strong hand griped his hips, so hard it would likely leave bruises later on. He was instead pulled back, before being lifted up, Reigen latching onto Mob by instinct to not fall, bitting his lips as how good it felt to be pressed up against him, Mob scent driving him insane.
He needed to make all of this stop, yet his heat muddled mind wouldn't help him focus on that, making him torn between trying to make Mob snap back to reality and just let him take care of him like the good alpha he know he would be.
He felt a bit weird at how carefully he was lay on the couch, not used to partners being so nice with him.
Mob finished pulling his pants and underwear off, battling with frustration to take his shows off too because they were in the way (Reigen had half a mind to be happy that Mob didn't just straight up ripped his clothes like many would have likely done).
Reigen cannot help but look down at the young man hungrily kissing up his leg, nipping at his skin slightly and rubbing all over him, trying to put his scent on him.
He hold his breath as Mob is now over his crotch, a hand teasing his hear cock slightly, although his attention truly lies onto the slit under his, oozing with warm slick, begging to be filled properly by an alpha.
And apparently, this is what Mob decides to do.
Reigen's mind whined when he saw Mob pull down his own pants, his cock springing out and standing proudly.
his mind too muddled to try and stop him anymore. Instinct and heat taking over him, making him crave the touch of an alpha. It's obvious there's no stopping this, he might as well let it happens so the unbearable heat and aching of his body can stop.
At least it's someone he trusts and cherishes.
There's no holding back the sounds he makes when Mob finally pushes inside of him, sliding with no difficulties with just how much slick he's been leaking.
the young man keeps fucking him roughly, hand keeping his hips in place in a strong grip. He can feel Mob kissing and licking his torso after he also took care of what was left of his clothes. nipping at his skin and trying to put his mouth on ever part of him.
Reigen is soon transformed into a moaning mess, grabbing onto Mob desperately, falling deeper and deeper into his heat. The more time goes and the better Mob smells to him to, the vague thought that he might have triggered his rut comes to him before going away just as quickly.
Reigen isn't sure how many time he cum, Mob hand relentlessly working on him while he keep fucking deep inside of him. He can feel his knot swell, stretching him even more widely than he was before.
This does send Reigen in a little bit of a panic despite how much more relax his body tries to be to take it all, being shushed by Mob, kissed in an attempt to calm him.
He shudders when Mob finally come inside of him, deep and locking himself so nothing would leak out.
Reigen weakly struggles when Mob bite off the cheap collar he was wearing, nearly screaming when he feels him bite down harshly on his mating gland, clamping down as he kept come more into him.
Reigen is too out of it to truly mind it, his inner omega singing with joy at finally being claimed like this by such a strong and powerful alpha, someone he knows will be able to take care of him (even though he very much shouldn't)
Reigen feels exhausted already, not as young anymore to keep up with this kind of activity. But it also a nice kind of exhaustion, different from all the last heat he's spent alone.
he nearly purr at the way Mob kisses him all over as he waits for his knot to deflate.
he's too out of it to try and tell him he should be fine for a while now.
Yet when Mob's knot starts to deflate he barely pulls out enough to get himself hard again, only to start all over again.
They spent all night like this, fucking on the couch, making the office smell heavily of sex and pheromones, he wouldn't be surprised if someone else could smell it even from outside the door. Reigen ends up passing out at some point after the third knot, Mob licking and nipping at the fresh bite mark on his neck.
When he wakes back up in the morning his body is arching and he still feel a bit woozy from his heat.
Yet when memories from what happened come crashing back on him he pale, guilt and panic washing over him. How could he have let something like this happen?
And with how much they had fucked, there was no way Mob's seed wouldn't have taken by now. And the mating bite, that was also something to worry about, even more greatly.
He was about to stand up and try to figure it out, when he was instead pulled into someone's lap. He immediately realises it mob's holding him close, making him stop struggling and nearly melting into his now mate.
"Mob we... I... I'm so-"
"Shh" Mob's quietly says next to his ear, something in him rumbling low and reverberating through the omega. "It'll be okay, I'll take responsibility for everything"
"But it's my fault," Reigen says, unable to stop himself from leaning his head to the side to leave access to his neck when he felt Mob so closed to him.
"It'll be okay" Mob reiterate again, kissing the painful mark on his neck, "we'll figure it out, don't worry".
Reigen nod choppily, trying to clam himself down. Sure, they would be able to think about it everything would be alright. He trusted Mob.
Everything would be fine.
the omega missed the way Mob smiled at his compliance, glancing to his school bag which hid within heat suppressant, which had been switched with sugar pills and heat-inhibitors.
A hand went to Reigen's stomach, carefully rubbing over it, purring in satisfaction when he smelled how satisfied Reigen seemed to be, even if unconscious. He could already smell some changes in his scent.

[#mobrei, bukkake, a/b/o]
Reigen wasn't so sure what had come over his mate, really he wasn't usually like this, even when in rut. Mob had never been this possessive, marking every inch of his body with bite marks, hickeys and his scent. As if it wasn't enough to make everyone know that Reigen was /his/.
Maybe suddenly having many alpha clients coming to the office hadn't helped, especially when many had tried being handsy and flirty with him. Probably didn't help that he had tried teaching Serizawa how to massage people, which had led to the other alpha's scent sticking to him a little bit due to Reigen being the test dummy. Poor Serizawa had looked pitiful under Mob's glare and low growl when he came back to that.
All of this cumulated with Mob's upcoming rut had likely not helped.
Reigen had never really been into being come onto, it felt kinda gross when it cumulated too much. Yet today it was as if Mob just decided to ignore his whine about it, doing it over and over again (not that he was allowed to do so inside without proper protection anyway).
Reigen could tell he was marking him some more like this, knowing it was kind of common for alpha to smear cum all over their omega to scent them more strongly, but Mob had never really shown any interest in doing that, even less with Reigen's distaste for it.
Reigen was coming down from yet another high of pleasure, feeling tired after the many rounds (he wasn't young anymore). He felt a bit confused when he felt Mob moving up the bed, straddling his upper torso and keeping him from moving much.
"Arataka" the alpha mumbled, hand working on himself, gripping at his forming knot.
Reigen was a bit too late to realise what he wanted to do to stop it, closing his eyes by instinct as Mob started coming all over his face.
Reigen could feel the hot semen landing on his face, some likely messing his hair up even more. Could feel drip a little, making a sticky mess of his face.
He didn't like it at all, maybe he should scold Mob later.
But his inner omega was revelling in the act.
He felt embarrassed at how he was whining and purring at the action, not moving at all as he took it all. Something deep in him overjoyed that his alpha was marking him like this, was using such a method to do so on him.
He felt drunk on the heavy scent it was leaving behind.
Really, the only thing he could smell at the moment was Mob, all over and around him.
When he finally opened his eyes again (not without cringing a little at some having landed close to his eyes and stuck to his eyelashes), he found Mob looking down at him, looking so pleased with what he had just down. He could feel the happy rumble coming from him, travelling through him and only feeding his inner omega even more.
They stayed like this for a while, Mob lazily smearing his come around, until he finally moved off of him.
He nuzzled against his mate's neck, kissing him and calling out to him as he carried him to their bathroom. At least his young alpha still had enough mind to try and make his mate comfortable after what he did.
Reigen hope this wasn't going to become a trend, even though instinct wanted it to.
Although, he would lie if he said he wasn't at least a little happy that Mob wanted to mark him that badly to show off who he belong too that he would use that method.

AgeSwap A/B/O where alpha Mob never really had his instinct awaken. He doesn't fight for dominance or get territorial with other alpha. He's not submissive to other, but he isn't bothering with that kind of stuff either.
Until Reigen present as an omega.
Then his alpha instinct spike and he feel lile he MUST protect Reigen or else he doesn't feel good. Glare and growl at any alpha that gets a little too close to the teenager. Is always within armlenght or Reigen, where its easy to pull him back if needed.
He's never been a touchy person, but he finds himself often touching Reigen. Nothing inappropriate of course, but thing he mever does with anyone. An arm thrown around his shoulder when sittint. Fingers brushing through his hairs softly. An arm around him or on his Shoulder as they walk. Sitting so close that their legs are pressed against each other.
Maybe his instinct push him to scent Reigen without knowing what it is, feeling proud and reassured when he can smell his scent mixing up with Reigen's.
Mob has never cared for showing dominance and what is his, nor as he ever cared much about other omega before. But Reigen is different and he cant help it.
And of course Reigen couldn't be happier aboutall this 🤭😌
I could imagine him being confused at first, only to slowly melt in the attention given to him and enjoy the way Mob get like this for him only.
Reigen who falls for Mob because of all this and tries to push the limits to see until where Mob will allow things to go, only to see that aside from some hesitation for bolder things, he'll do or give him anything.
He feels very loved like this 😊💜 (Even tho he wonder what exactly Mob-shisho feels towards him, but thats okay, its seems good enough for now)
Lol just thought of what would be Ritsu's reaction to seeing all this. Happy that his nii-san is finally allowing his instinct to come out? Or horrified because its all directed towards that one teenager omega?
Also people at school (and maybe home) looking at Reigen wondering if he has a partner or something with how strongly he always smells of an alpha
Dropping this here so I won't forget (and to extend on later):
#mobrei where Reigen is a pretty plain and normal beta, while Mob ends up presenting as an Alpha. He's pretty happy for Mob about the news, but Mob doesn't seem like he wants to find an omega partner
Like, maybe when Mob's present he surprised everyone a little bit because usually, alpha aren't smaller. But Reigen is happy about it (not that he would have acted differently if he was an omega, he's just somewhat relieved it will be easier for Mob in life like this)
But with that, Reigen helps him as best as he can. Especially since somehow, Mob always comes to him for advice about alpha, despite Reigen just being a normal beta and knowing there are alpha in Mob's life that could help him better.
He also tries to help Mob get ready for when he'll find an omega with whom he might bond and mate. After all, who wouldn't want Mob?
But as Mob grows older, taller and stronger, Reigen starts to realise that he doesn't seem like he's seeking an omega?
And he doesn't actually notice the way Mob focuses on him /A Lot/.
Mob who innocently asked how to scent someone so he knows how to do it later on and Reigen let him try on him, because what bad can it cause? He's just a beta after all.
But with that, He ends up walking about with an alpha whose scent is actually pretty strong (he just doesn't smell it that much anymore with how used he's to be around Mob).
Then doesn't fully notice when Mob scents him discreetly, trying to mark him in a way.
And with that starts his small possessiveness over Reigen, which keeps growing.
And poor Serizawa, who's also an alpha, who has to deal with Mob's scent and aura feeling overpowering and the way he sometimes directly looks at him when he decides to scent reigen.
I can only imagine Serizawa being this poor alpha who never really got socialised (after all he was away from people for most of his life) and who only wants to have a good relationship with his boss, only to have this high schooler glare at him and making clear what is his
And it's probably only as Mob grows older, tall and stronger than Reigen really realises that Mob is *really* not interested in finding himself a mate and that he seems too focused on him.
Could see Mob eventually confess because Reigen was trying to push him to date others.
and while it's not unheard of or taboo for alpha to date outside of omega, the percentage that does so is still pretty small.
And Reigen just can't see himself as good enough. Mob is this tall and strong alpha who could be categorised as some of the best there could be and somehow he settles on Reigen, who's a plain middle-aged beta?
Of course, this would have a happy ending 😌 because of course Reigen feels more than platonic feelings for Mob, but just always buried the down because OBVIOUSLY Mob would look for better.
Lol, now I can also imagine in the times when Mob just started scenting Reigen, he comes across Ritsu who looks at him weirdly and mad because yeah, sure, he nearly always smells like nii-san but not /like this/. but maybe one day he witness Mob doing it secretly and realise this isn't a "Reigen is being the problem" kind of thing, but rather his brother being the one doing the thing on his own accord
Or also
One time on Mob's break from college is the one going to visit is actually Reigen (Mob asked so nicely and he's curious to see).
They come across some of Mob's classmates, and maybe one of them is a cute omega who clearly as a crush on Mob.
Reigen teases Mob about it semi-discreetly and Mob gets a little bit mad about it, denying it. Poor little omega who got their hope smashed like this, but also realised that no one else would have a chance once they look more closely at the way Mob treats Reigen.
What's Reigen's grown accustomed to over the years, (like standing really close to each other, Mob throwing an arm over his shoulder), looks really pretty territorial and semi-possessive coming from an alpha, but instead put towards this older beta who seems oblivious to it
I just like the idea of Reigen so not being used to being around alpha (aside from Serizawa, but he might not be the best example), that he barely questions any casual claim Mob puts on him that isn't too obvious. He just thinks that's how Mob act with people he's close to

I need more beta Reigen honestly with Mob just latching onto him and being possessive and now I'm thinking Age Swap AU.
Reigen who's a bit sad to learn he's just a beta, but happy that shisho doesn't seem to mind.
Meanwhile, Mob probably feel possessive and protective of Reigen and whatever he would have been, he would have still latched onto him. An omega would have been nice, he could have shown him he can take good care of him, but a beta is easier to deal with than an alpha
And while Reigen is a bit sad to just be a beta (he would have loved to be an alpha) he recovers quickly when Shisho shows that he still likes him none the least, not really noticing the way Mob gets worse over the years when it comes to protecting him and keeping him close
And Ritsu is too slow to realise it, when he notices the way Mob glares at anyone who even just glances at Reigen, the way he casually scents him (leaving Reigen a little puzzled because he's still a bit too young to get it), the way he always keeps him close
it's too late his brother is too obsessed with Reigen and he knows that if he, another alpha, tries to interfere it will probably turn bad, he doesn't really think that him being his brother would fully keep Mob from getting mad (though maybe he would be nicer on him than other)
But also anyone who knows them does see the way Reigen as actually has a pretty positive effect on Mob. If he gets overwhelmed Reigen just needs to talk to him softly and stay close and it helps Mob calm down. Sometimes he'll hug him and Reigen's scent, even if pretty muted because he's a beta, helps immediately calm him down
It's actually pretty funny to imagine this tall dark alpha who was probably about to go 100% being suddenly semi-calm and docile because this young beta just waltzed in and hugged him, murmuring reassurance to him
Although letting Mob be this close, possessive and protective, as calming as it can be, is a double edge sword, because he totally goes berzerk if anything bad happens to Reigen when he's not with him (he wouldn't let anything happen to him)
I just love fucked up Age Swap Mob who never really had anything good in life and latch onto this loud little guy who really wants to get psychic powers
