Work Text:
Going back to work was hard. Being separated from his little omega’s sweet pussy was awful, even if it was just for a few hours while he worked. But he powered through because he needed to provide for all the pups he was going to put in his mate. Shouta had found them a nice house with several bedrooms perfect for a large family. His previous habits of never spending the money he made as a hero and teacher came in handy as he was able to pay for their home, furnish it, and still have money left in savings. It would be ready by the end of the month and he couldn’t wait to fuck Izuku in every room.
Shouta had never thought he would be one of those alphas that would take their omega everywhere with them. After a week with Izuku’s cunt constantly nearby for the taking, that changed. It wasn’t uncommon to see an alpha leading their mate around by a leash, alphas were known to be incredibly possessive of their omegas. So no one thought it weird that Shouta was walking into UA with an eight year old in a collar attached to the leash in his hand.
Bonded pairs fucking in public was commonplace, both because of alphas love of showing off their omegas and because they were territorial. Yes, they loved showing off their mate and proving they had the best omega, but the only person allowed to do more than look was that omega’s alpha. Another alpha (and sometimes even a beta) so much as looking at their mate for too long could make that alpha need to publicly stake their claim. So everyone saw the little boy trailing after his alpha and stopped to watch in the hopes they would get a show.
He ignored them, the sooner he got to work the sooner it would end and he could spend as much time as he wanted fucking his mate. So he led Izuku to the teacher’s lounge. Of course his idiot friends rushed toward them the minute they entered the room. Everyone knew he’d taken time off because he marked an omega and Hizashi and Nemuri wanted to see the kid for themselves. They both cooed over how cute Izuku was, making the omega blush and try to hide behind Shouta.
Nemuri’s omega stood slightly behind her alpha. Not out of shyness like Izuku, but because Nemuri was very strict with her omega. Which was understandable considering the woman had paid top dollar for an omega with a pretty mutant quirk like Mina’s. Plenty of parents keep their omega pups at home from the minute they present until they can find an alpha to pay for the honor of mating with them. The practice had the benefit of ensuring an omega would be provided for as well as making the family some money. Quirks that made someone “exotic” like Mina’s pink skin and little horns always made the omegas that much more expensive.
The alpha woman was particular in her tastes in omegas and had searched for a long time to find an omega that fit them. Then, once she bonded with Mina, she had trained the girl to behave exactly the way she wanted. The girl was another omega leashed to their alpha, so once Nemuri finished congratulating Shouta on his adorable mate, she tugged the leash to signal that Mina could introduce herself.
Mina stepped forward with a kind smile, her hand resting on her swollen stomach. (She was two months away from pushing out the couple’s first pup) “Hello Izuku, I’m Mina. We’re gonna have loads of fun together at the omega center!”
Izuku offered her a smile and asked in a timid voice, “Hi Mina, can I touch your belly?”
The girl looked to her alpha for permission and, after getting a nod from Nemuri, told him he could and moved her hand so Izuku could try to feel the pup kick. The three alpha friends watched with smiles as Izuku excitedly cried out when the pup kicked his hand and started asking Mina questions about the gender and names.
Shouta was glad Izuku would have a friend to spend time with while he was in class. UA, like every place of employment, had an omega care center where alphas who leashed their omegas could drop them off to be cared for by adult omegas. It was set up since so many omegas were mated as children and couldn’t be left alone. Sure, they could keep attending whatever school they’d gone to before they were claimed, but many alphas wanted their mates as close as possible.
The only people allowed in omega centers were omegas, their pups, and their alphas. Once a leashed omega was old enough, they moved into a caretaker position to watch the younger ones and teach them to care for their pups while their alphas worked. In the rare instances where there were no younger omegas to watch, they spent their time relaxing and socializing with other bonded omegas. It was a good place for alphas to leave their omegas and not have to worry about them.
Shouta and Nemuri led their still chatting omegas to the center, which was accessed through the teachers lounge. As soon as the leashes were off their collars, Mina dragged Izuku off to show him around and the alphas left to go to work. Throughout the day, Shouta stopped in to check on Izuku who was having a great time playing with the other omegas.
He was always happy to see his alpha and didn’t care that he had to stop playing to be Shouta’s toilet for a bit. The freckled omega was all too happy to open his mouth and drink down Shouta’s piss and never hesitated to stop whatever he’d been doing when his alpha entered the room to do it. Shouta was pleased that being around others wasn’t having any negative effects of Izuku’s training.
During his free period and lunch, just like every other alpha with an omega in the center, Shouta came in to fuck his mate. The room was a mess of naked couples during lunch, the alphas pounding into their mates on the couches, floor, or tables while they had spare time. The pups played quietly while their parents fucked, alphas were known to fuck their omegas wherever and whenever the mood struck, so they were all used to seeing their parents go at it.
When he showed up at lunch Shouta walked over to where Izuku was drawing with Mina, picked him up, pushed aside his panties, and slammed his cock into the boy. He’d dressed Izuku in a skirt that morning so the panties were the only barrier to his prize. Izuku let out a loud moan as Shouta stuffed him full of cock, holding his legs and pressing the boy’s back to his chest so that his pussy was on full display when Shouta began fucking Izuku’s tiny body up and down his cock. Mina was watching Izuku’s pink pussy stretch around his alpha’s cock, the smell of her slick filling the area as she became aroused watching her new friend getting fucked.
She was never allowed to touch herself, only Nemuri could give Mina pleasure, so the girl watched Shouta use Izuku like a cocksleeve biting her lip and pressing her thighs together for any relief. Slick was dripping from Izuku’s cunt onto the floor and the boy was looking down at Mina watching him getting pounded. The feeling of being watched was amazing when it was clear the other person was turned on, unlike the crying his mother had done Mina clearly loved what she was seeing. Knowing someone was seeing how good his alpha made him feel and enjoying it had pleasure burning in his veins.
Then Nemuri entered the room and Mina immediately stood and pulled off her dress and panties. She presented for her alpha and Nemuri ran a hand over her pink ass before sitting down facing Shouta and Izuku and pulling out her cock. “Ride me while we watch your friend get fucked, Omega.”
Doing as she was told, Mina climbed onto her alpha’s lap and lowered herself on Nemuri’s cock. The woman had to help her stay steady because of her large stomach, but the pink girl started bouncing as soon as she had that dick inside her. Izuku watched his new friend riding a cock like a pro and felt his pussy dripping even more slick. Mina’s belly was large enough to partially hide where Nemuri’s cock was buried inside her, but her milk swollen tits bounced enticingly and Izuku couldn’t stop imagining when he would look like that.
His alpha was very vocal about wanting to pup him and seeing a pupped omega getting fucked made Izuku long for it. He wanted to please his alpha, to show that he was a good omega that would provide all the pups he wanted. Izuku wanted to be so swollen with his alpha’s children that there was no question about how much he pleased his mate.
The thoughts swimming around in his head made Izuku clench down on Shouta’s cock and the alpha was in heaven. He had seen the woman fuck her omega countless times, but watching it while she watched him hammer into his own mate was so much better . The sounds of every omega present being taken by their mate surrounded them, the scent of multiple couples fucking added to his desire to knot his omega. Shouta used his grip on Izuku to move the boy faster and faster on his dick until the kid was shouting nonsense as he came.
Shouta was close enough to Nemuri and her mate that Izuku’s come splashed across Mina’s face. The sight of his omega’s useless seed covering the pregnant girl was enough to make Shouta’s knot swell inside his cunt. Nemuri smiled wickedly, “Sho, it looks like your mate made a mess. You should make him clean it.”
Nemuri held her omega in place while she ground her hips up into the girl’s cunt. Returning her smirk, Shouta adjusted Izuku so he could lower the boy’s face to Mina’s. Nemuri was always into seeing omegas together and she knew Shouta shared her feelings. “You heard her, Omega. Clean up your mess.”
Izuku’s tongue darted out and licked his own come from Mina’s face, groaning at the salty sweet taste. Shouta was still spilling his seed inside the kid and watching his pink tongue lap at the other omega’s face had him grinding his knot against Izuku’s slick walls to prolong his climax. Mina had started working her hips frantically against Nemuri’s and began begging her alpha to let her come. Taking pity on her mate, the woman gave permission and soon Mina was trembling through an orgasm while Nemuri’s knot popped inside her.
Once they calmed down from their climax and his knot started softening, Shouta emptied his bladder inside Izuku before plugging him up and returning to work. He left the room filled with fucked out omegas laying where their mate had left them with Nemuri walking next to him. “You really found a good one, Sho.”
