Izuku was an indecisive person as he could always see the good sides of things and he could never ignore them.
For example, he wanted to buy a flower like an orchid or sunflower for his mom. He knew his mom lived orchids but her favorite color was yellow and he knew both would make her happy for different reasons so he bought both and she was even more happy.
Of course, something’s don’t go that way. Izuku does have to decide but sometimes he’s not very sure about. Being bullied in his younger years took a toll on his confidence and still showed its effects in his adult life.
But this is one of the times being an omega actually helps him. His omega points out things he may like, things he’s craving, or certain smells he likes so he doesn’t have to test it out.
He has no other choice but to trust his omega! It’s never let him down before.
Izuku presented later than his peers but has a lot of experience. He’d say that he knows himself pretty well and his omega too.
He was familiar with the rush of lust that flowed through him during heats that yearned for a knot but never actually had the urge to swirl his hips to catch it or even ask for it in his delirious state.
Not until he started dating Kacchan.
Kacchan was the best alpha, the alpha of his dreams. Izuku thought he’d never be with him and he still doesn’t believe it.
They’ve been together for 3 years, bonded for 1, so they’ve been spending heats and rugs together. Honestly, when Katsuki is in the throes of his rut it’s his favorite time of the year.
Izuku felt the tingly warmth up his spine and he knew it was time. He rearranged his nest a little before laying down for a nap.
When he woke up, there was a sharp jaw skimming his and a hand stroking his hair.
Izuku purred. His body was warm all over and he felt a little floaty when the alpha was near.
Izuku let out a breathy giggle, “Hi Kacchan.”
Katsuki hummed a greeting and didn’t pull away until he was completely content with scenting Izuku.
Izuku whined at the loss but Katsuki quickly comforted him with soft neck kisses and a hand down his shorts.
“You smell fucking amazing.” Katsuki grunted.
The alphas other hand pulled his shorts down to look at Izuku’s cunt better. It was glossy and made a slick noise when he put two fingers in.
Izuku arched into it, enjoying the eagerness in the fingers going in and out of his cunt.
“That’s good, I’m ready .”
“Just a little longer, I don’t want you to rip my dick off.” Katsuki joked.
“Kachaaaaaaan-“
“Okay, okay. I got you.” Katsuki spokee like he was annoyed but he wanted it just as much as Izuku did. He reached over to the nightstand and slipped on a condom before pushing his pants down and letting his cock spring free. It taps on Izuku’s little one before Katsuki grabs a hold of it and drags it down over his lips to push against his hole.
It glides in slow and smooth and Izuku’s eyes flutter closed in utter bliss. He’s not deep into his heat and his omega is barely trying to take control but everything feels so right.
“Feels so, ah, good.”
Katsuki leaned down so that their foreheads touch and their lips brush with every thrust. Red eyes locking on green ones.
“You feel fucking perfect.” Katsuki says against his lips.
Izuku audibly moans, shaking as Katsuki hits his spot with just about every thrust.
Izuku’s hot and full of Katsuki but he wanted more. The obscene sound of his slick squelching was embarrassing but alluring and for some reason he thought of how much better it’d be raw.
Their hands interlocked as the alphas eyebrows furrowed to focus on the omegas expression.
But Izuku wanted to feel Katsuki for real. The rubber between them makes Izuku irritated and his omega start to rise.
He wanted his alpha to pop inside of him and fill him to the brim. He wanted to know how it felt to ooze out of him and he was so sure he wanted it too.
Katsuki let go of one of Izuku’s hands to cup his face and asked: “What’s wrong baby?”
Izuku whimpered as his alpha started to drag slower against his walls. What was wrong was that his alpha wasn’t trying to pound a baby into him.
“Knot, knot me alpha.”
Katsuki’s jaw dropped. Asking to be knotted was practically asking to be impregnated and fuck it turned him on, Izuku smelling like milk and his cunt swollen all the time. But he wanted to make sure Izuku wasn’t just saying what his instincts wanted. He needed to know what Izuku truly wanted.
“Are you sure? I’ve never.. done that before.”
Izuku’s hand squeezed Katsuki’s. “Me neither, but I want it to be with you, I want to have Kacchan’s pups.”
“Fuck, you can’t just say that.” Katsuki kissed him passionately and licked over the omegas teeth.
“But it’s true..” Izuku said through heavy kisses.
Katsuki abruptly pulled out to throw off the condom and Izuku threw his head back into the pillows with a groan as his cunt clenched to keep the alpha inside.
But soon enough the alphas tip was at his entrance again and sliding in his slick.
“You want me to knock you up with my pups, huh?“
Izuku nodded and rolled his hips trying to coax the alpha back inside of him.
“Don’t worry, I’ll fill you up baby.”
“Mmm yeah but that’ll make them bastards.” Izuku said, abstinent-minded.
Katsuki started to push in, inch by inch.
“No, I’ll marry you, get you the wedding of your fucking dreams. Have a bunch of pups running around.” He whimpers towards the end as Izuku’s heat sucks him in.
Katsuki hit his pelvis with a thud only Izuku could feel and he latched onto Katsuki’s shoulder’s like a lifeline.
“Kacchan!”
Katsuki held the omegas legs up to his ears as he slammed into him with no remorse. It made Izuku sob out his name like a prayer and let out throaty moans as Katsuki. The slapping of their skin was so loud and his omega was still drooling with slick which made it even more erotic.
Izuku’s nails dug into his back but he didn’t care, and he could feel Katsuki’s knot build up and press against his lips every thrust but he couldn’t hold on any longer.
Izuku gasped, “Mngh, I can’t-“
The omegas heat squeezed him for a moment before spawning around his cock and he made sound through his teeth that was like music to Katsuki’s ears.
“I’m almost there too ‘Zuku, hold on.”
Izuku nodded with teary eyes and pushed onto the alphas cock when he pushed in until his knot finally slid in. It was huge, as big as his fist and it was inside his cunt now.
Katsuki grinded it into him and made the omegas thighs clench from the rushing pleasure. Then it began to expand and it popped inside him and he felt so full.
Katsuki let out a grunt as he spilled inside, his arms wrapped around Izuku protectively as ribbons of cum shot into the omegas uterus and filled it up, it probably shot up all the way into his tubes, it was so much. But it felt amazing, his omega purred as he moaned long through the whole process.
“Thank you Kacchan.” Izuku said, groggy but more satiated than he’s ever felt before.
Katsuki dropped onto him, still locked together. “I should be thanking you.” He laughed.
“Feels good to be so full of you. I’ve never had all of it before.”
“Yeah? Bet you’ll never leave me now, huh?” Katsuki teased.
Izuku pulled his head up from his chest to look into crimson orbs. “I was never gonna leave you anyways!”
Katsuki swatted his hand off, and laid back down on the omega’s chest.
“Yeah, yeah I know. Now rest, before your gonna be begging for more in a few hours.”
