MobRei | Mob Psycho 100 Omergaverse + Age Swap AU 24-02-2023

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

MobRei | Mob Psycho 100 Omegaverse + Age Swap AU 29-12-2022

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
