Nest

#threadsave omegaverse

It starts innocently enough - a warm jacket that's not returned after walking around the premises, a discarded shirt that should have gone into the hamper but is instead sequestered away, hoodies and books read by the Precepts who Izuku enjoys hanging out with, a cardigan from Himiko-chan the last time she visited...

He doesn't realize there's a problem at all until he finds himself moving a number of Eri's fluffiest toys (and the girl herself) into his own chambers.

It's the early afternoon and Eri is currently with a tutor when Izuku realizes he's fucking getting himself ready to nest for his heat. "Oh fuck."

A check of the calendar on his phone showed that he's early by almost a month and a half; no wonder Kai and Dabi hadn't been on his case to slow down a bit and stop juggling so many projects. Well then, he has to start planning.

Kai looks up from his paperwork when his phone pings. Grabbing the object, he checks the notification, only to be surprised that it's Amazon thanking him for his order. He thumbed through the item list, frown growing; what the hell would Dabi need so many blankets? He's about to call the younger man to ask directly but then he sees what else is in the next day order - knotted dildos, heat aids, and scent neutralizers that's set up to help remove pheromones in the air. Kai checks his calendar again. It seems their Bunny was early this year. He still calls Dabi though.

As soon as the call connects he hears a flash of fire and a distant scream. "What is it?"

"Block off some time with your League of Idiots - Izuku is in preheat."

There's a pause, Dabi responds "I'll be at a pickup point in thirty min."

"Yeah, Setsuno will get you. See you soon."

It's a pity that the League and the yakuza had poor relations, that warp quirk would have been convenient to pick up his beta.

Dabi steps into the compound, wound up with nervous energy. This was going to be the third heat he will share with Izuku and Kai. As a beta, Dabi made sure that the two didn't kill each other during the throes of passion and help ah, keep Izuku warm while Chisaki recharges.

Still, omegas tend to only have heats 4 times a year and Izuku's last one was just over a month ago. Unusual but not a problem, in his opinion; Dabi is a man who's favorite past times are fucking his boyfriends and laying waste on false heroes.

The path to Izuku's quarters is one he remembers well, but Setsuno still trails after him as a precaution. When they make it to his main room, the other man dips out. Dabi knocks twice before opening the door and is instantly hit with the scent of preheat interlaced with Izuku's. "You in, bunny?"

From the mess of comforters & shirts, Izuku's mossy green head pops out. "Dabi! You're here!" He tries to extricate himself, only to get ensnared by his nest and pitching forward. It's only Dabi's quick reflexes that saves Izuku from face planting on the floor, catching the teenager to keep him from falling. Dabi tsked at the sight of it. "You know Chisaki is gonna bitch about the clothes again."

"He can remove them when I'm dead," is Izuku's mumble. Last heat, the alpha and omega had a row when Kai found one of his shirts with a small bloodstain on them in the nest and proceeded to try and wash everything before they could have sex again.

It ended with a lot of screaming, crying, and Dabi burning the offending shirt and threatening to take out the whole complex if they didn't start making out again.

Dabi considers going through the nest to check and make sure there's no Unidentifiable Stains(TM) but gets distracted as Izuku pushes off of him to lay back down within his organized clutter. The boy leans back, practically preening at the attention and giving off the scent of an omega ready to be bred. Dabi isn't sure if it's the pheromones affecting him (despite being a beta) or genuine lust and affection that makes his dick twitch in interest.

"Do you want to play~" Izuku asks, voice a purr.

Before Dabi could say yes, there's a knock and the door opens. Kurono comes in, arms laden with a number of packages. "Your packages are here, anesan."

Izuku's sound of joy had both of then blushing. Kurono pointedly looks away, color high on his cheeks. Dabi takes pity on the yakuza, taking the boxes, so the alpha can scurry away and not do something to Kai's omega that would get him burned, shanked, or overhauled. The omega made grabby hands until Dabi handed them over so he could open them.

"Fucking..." Dabi grabs one of the dildos; it was ribbed and knotted. "What do you need all of this for?"

"I can't expect you and Kai to keep me entertained all week."

The man huffs, dropping the sex toy so he could muss up Izuku's hair. "One of us will he with you the whole time, Bunny. We're not going to leave you unsatisfied, got it."

Dabi can hear Izuku sniffle so he pulls the boy into a hug and that is how Kai finds them when he comes through the door. The yakuza watches intently taking off his jacket and gloves as the two engage in a tender moment before the omega smells his alpha. Izuku perks up and looks over Dabi's shoulders, pheromones releasing in his excitement.

"Kai!"

"Honestly, I'm surprised you 2 weren't having sex already."

"I was considering, but you get butthurt when we start without you," Dabi chuckles. He releases Izuku who shimmies out of the last of his clothes, more than ready to get fucked.

Kai gives an amused laugh even as he and the beta start taking off their own clothes, following the omega into the nest. They'll have time to talk more, to figure out why Izuku's heat was early and other things. For now, Kai just wants to sink himself into the warmth and heat of his little omega, to watch Dabi become undone as Izuku sucks all the cum out of him.

Yeah, they can tall later.

Chisaki watches Izuku fucks himself on Dabi, ass stretched wide over the beta's thick cock. The boy whimpers, hands held tightly in Dabi's grip to keep the omega from playing with his cunt and cock. "P-please," he whines, even as he pumps his hips. As an omega in heat, not getting something in his needy cunt is torture, but Dabi knows the rules: he can fuck and play with whatever holes he want except for Izuku's cunt - that was only for Chisaki. The yakuza watched as Izuku is filled again and again, crying out. He could wait for Dabi to finish, but the pheromones in the air grew heavier, needier, and combined with his two pets whimpering in need... well... why delay?

Chisaki quickly sheds his clothes, lazily pumping his length with a gloved hand as he lines himself up. Izuku was often wet and needy on most days, but in the throes of heat, the omega was utterly drenched, no need for lube because his natural slick allows Chisaki to fuck into him with ease, Izuku taking his alpha so well with only a hiccup of need. Dabi let's go of his arms which he quickly winds around Chisaki's neck, panting.

"Alpha, alpha please, knot me!" He whimpers.

It's hard to deny him and the moment Chisaki feels Dabi cum inside Izuku's ass, he thrusts up enough for Izuku to get caught on his knot. The choked off gasps and grunts of pleasure is heady for the older man, enveloped as he is.

As Dabi pulls away, Chisaki grabs his face with a gloved hand and pulls him into a heated kiss that leaves Izuku mewling. He can feel the fire user smirk against his lips, but he doesnt care, deepening it for a moment before letting go, allowing Dabi to stumble away, before pulling Izuku further down his knot much to the omega's pleasure

Chisaki knows Dabi is watching, just waiting for his body to recover enough for another round. Maybe when the omega is good and fucked to sleep, he can give Dabi a taste of his cock too.
