Chapter Text
‘Deku’s been leaving the gifts. Deku’s been the one trying to court me. Deku, the little itty-bitty alpha Deku.’ Katsuki thinks on a loop, frozen in shock as the greenette scoops up her tall omega and carries him home. If the blonde’s brain wasn’t in the process of rebooting, he’d be very impressed the alpha can carry him, but then again, she is a prime.
They get home a few minutes later, the smell of anger and distress still soaked into their clothes.
“Izuku, what happened?!” Mitsuki shouts, smelling the pair first while having a cup of tea with Inko at the dinner table, talking about the greenettes’ trip. The two adults rush over to their pups inspecting them, when they find handprint bruises on Katsuki, they lose it.
The increased amount of pheromones force Katsuki out of his thoughts and he subconsciously whimpers, pushing his face into Izuku’s neck gland, wrapping his arms tighter around the prime’s shoulders.
“What happened?” The blonde dam asks, taking a step back when she hears her pup’s distress.
“Apparently someone claimed my gifts to Kacchan as their own and then while I was gone tried to force himself on him. I got there before it could escalate beyond the bruises on Kacchan’s wrists, but not even that should have happened.” Izuku growls, that iniquity and self-hatred bubbling up, tears pricking her eyes as she cradles the omega closer.
“Not your fault…” She hears, mumbled into her neck, making emerald eyes widen before glancing down at the blonde teen. “Nest now.” Katsuki says before she can ask what he meant, but when she heads to the pack nest, he whines, halting her mid-step. “/My/ nest.”
After the last 6 days without Deku and after that disaster with the second-rate alpha, Katsuki wanted nothing more than to curl up in his nest with the greenette, hating how his inner omega felt absolutely smug that the blonde was finally accepting the prime in some manner.
With her cheeks a dark shade of red and pleased alpha scent emanating from her, Izuku wastes no time and rushes towards the stairs towards the Bakugou rooms. Forcing her little legs to reach their destination as fast as possible.
When they enter the omega’s room, she still doesn’t set him down, walking over to the large circle of pillows and blankets until something catches her eye.
“Kacchan, is this- are these my clothes?” The greenette asks, gently setting Kacchan down to reach for her shirts.
“Don’t touch those!” Katsuki shouts, startling the alpha as he reaches for the claimed clothing.
Emerald eyes go wide in shock before a rumbling alpha purr escapes her, and she practically melts into a puddle of happy green goo on the floor.
Katsuki’s red all the way up to his ears when he takes off his school jacket, thankful it’s the only piece of clothing tainted with that horrid alpha’s scent. He throws it in the hamper before grabbing his lounge clothes and heads for the bathroom, not even glancing at the greenette.
For fear of offending the blonde, Izuku stands there frozen, waiting for the omega to tell her what to do. Her body may have been happy to stay still, but her eyes can’t help but look around, only for her heart to nearly explode with joy when she sees all her courting gifts laying around the room. All of them, except one, the handmade black lace with orange and green gems weaved into the delicate fabric with a heart shaped pendant engraved with her name, collar. Her heart sinks at the single discarded gift.
“What are you pouting about?” Katsuki asks, startling the greenette as he walks out of his bathroom, wearing a tank top and sweats.
“Oh, nothing, sorry.” Izuku says, putting on a fake smile as she turns towards the omega, ready to accept her fate, even if it meant she’d never get to mate her Kacchan, only for her jaw to drop and eyes to go wide before filling with grateful tears. Her heart begging for a reprieve, because there, around that beautiful pale neck was the collar she spent 6 months making through trial and error. “That’s my- that’s my- you’re wearing my-” She stutters out, instincts /dying/ to rush the omega and give him her bite. ‘Oh no.’
“Collar, yes.” Katsuki says, sheepishly before putting up his fake bravado again. “Now that I know it’s you that’s been leaving the courting gifts, I don’t see why I shouldn’t put it on.” He says, heart racing as he walks over to his nest, ears still tinted red.
“Kacchan’s so perfect.” She can’t help but say dreamily, crooning for the omega, smiling dopily as she melts in her spot.
“Ya, ya, now are you going to come here or not?” He asks, sass and all.
Izuku doesn’t waste a second before racing towards the blonde and carefully hopping into the nest, letting her scent fill the space, an affectionate emerald gaze as she settles beside the omega.
That’s when that feeling comes back.
‘/Omega is accepting our courting after a YEAR, this is a reasonable next step./’ Her inner alpha points out, smirking wickedly as heat starts building under her skin and her primal side starts wrapping around her conscious mind.
If Katsuki notices the slight change in the alpha’s scent, he doesn’t say anything, instead for the first time since he presented, he lets his omega share the reins with him. At least, that was the plan.
‘/We accepted alpha’s courting; we’re wearing the collar and invited them into our nest… Our heat is close; alpha will make us feel good this time./’
The beast’s comment makes his eyes shoot open, not realizing they’d shut when Deku had curled around him, nuzzling into the crook of his neck.
When he feels the first lip and graze of those large fangs against his sensitive skin he can’t help but whine needily, letting his head fall to the side, giving her more room, body going lax as pre-rut pheromones mingle with his pre-heat.
With the last shred of rational thought, Izuku pulls out her phone and sends an alert to the parents' downstairs, not caring anything past that before dropping it to the floor and rolling Kacchan over onto his back, marveling at the flushed, lewd display under her, feeling her cock filling out and her pussy slick. Fuck, she didn’t care how they fucked, just as long as they did.
Katsuki can barely hear the scent and sound barrier slide over his door, but just because he heard it, doesn’t mean he registers it. He feels like he's burning alive, something deep inside him begging for things that makes his entire body flush in embarrassment, never being one to even think about watching porn.
“Kacchan, omega, I- I need you to-to tell me wha-what you want.” Izuku grits out, venom dripping down her chin as she pants, fingernails turning to claws as they cut into the bedding under them, using every ounce of will power to protect her love.
“I-” Katsuki starts, only for the words to die on his tongue. What did he want? This was all so new to him, but gazing up at the prime that’s always stuck by him, protecting him, even from herself, he finds her the most beautiful creature in history. Her wild curls stuck to her forehead with sweat, pupils slitted in determination, and those fucking freckles. Those sweet angel kisses dotting her cheeks and traveling down under her shirt collar. Fuck, he wanted to see where else they were on that short, fit body. With one last erotic thought, he makes his choice . “I want you to claim me, Izuku… alpha.” He says, relaxing, giving the greenette a nervous smile.
Emerald eyes go wide in shock, a deep rumbling purr making her chest vibrate as she slowly moves to start removing the omega’s clothes, the blonde following her lead.
The second the last piece of clothing is removed, they freeze, their virgin brains overriding their need to mate as their cycles begin to hit full force. They are both dripping slick and precum.
“Kacchan, may I-” Izuku starts, choking on the words as instincts influence her to roll the confused omega over onto all fours. Once she has him where she wants, she takes her cock in her hand, knot already swelling before mounting him.
“Izuku?” Katsuki asks, bewildered until he feels her tip trace along his crack before slipping between his legs to nudge his folds, easily slipping past and into his pussy. He shivers, arousal and anxiety making him slick more as she slowly pushes into him, both trembling, only for him to let out a high-pitched cry when she breaks through his hymen, the greenette moaning in relief at being fully seated in her omega, that hot heavenly heat gripping tightly around her cock. “Oh, god, alpha, move!” He cries, wiggling his hips.
