Katsuki yells in frustration as he drops the ice creams in his hands. One mint-flavored, one orange-flavored ice cream balls land on the floor, already starting to melt.
“God damn it, you brats! Watch the fuck out!” Katsuki calls to a group of pups who were long gone.
“Kacchan! Are you okay?” Izuku comes in hurry, then stops as he eyes the ice creams on the floor. “Aw,” he tilts his neck, rosy plump lips moving downward.
“Fucking brats bumped into me. Do you want me to go take another one?”
“No, it’s okay. Let’s just relax.” Izuku sways his head, prompting Katsuki to walk to their sunbeds.
The hot sand almost burns his feet even with the slippers. Taking a seat on their spot, Katsuki tries to relax his muscles, the burning sun circulates at its peak, it must have been around noon.
“Let me,” Katsuki says, seeing Izuku’s desperate attempts to apply sunscreen on his back.
He gently applies the sunscreen, leaving no spot uncovered. “Y’know your skin is so sensitive, did you apply it right in other places?”
“I don’t think there is a wrong way to apply sunscreen, Kacchan.” Izuku chuckles, which makes his shoulder shake slightly.
“Don’t come crying to me when you burn.” Katsuki scoffs, rolling his eyes.
“Oh,” Izuku pauses, “but I’m used to heat.” He retorts, turning around to face Katsuki with a devious glint in his bright eyes.
“Oh yeah?” Katsuki challenges, a sly smirk wavering on his mouth. Leaning down, he captures Izuku’s lips with his own. First, he bites his lips, licking them, savoring them. Then, he pushes his tongue and deepens the kiss; god, every time he kisses Izuku, it still feels like the first time. Wet, warm, and so captivating; just like Izuku himself, his mate, his Omega.
Izuku pulls back when Katsuki was about to move him on his lap; seeing Katsuki’s irritation, Izuku huffs, “Kacchan, there are pups.”
Katsuki kisses Izuku one more time, a quick peck on his now-swollen lips, then he withdraws. “We should’ve gone to one where they didn’t allow pups.”
“Maybe… but our schedule is tight as Pro-Heroes, so available hotels were limited. Plus, I’m happy wherever I’m with you.”
Katsuki grins, ruffling Izuku’s unruly hair, “You sappy ass nerd. I’m happy wherever I’m with you, too.”
Okay, Katsuki is starting to realize that maybe he does not hate pups as much as he initially thought. Or, to be more exact, he is pretty sure that he did; at the start, at least. That is until he saw his Omega playing around with pups.
Izuku is a natural caregiver. He would undoubtedly make a great mom, and Katsuki has always known this, but seeing its live example of it short-circuited Katsuki’s brain, and apparently all of his logical line of thinking.
The mother who sat beside them asked for Izuku and Katsuki to watch over her pups till she gets back from her call, an important call that is job-related, as she stated.
(“It might take a bit long, so I don’t want to leave them alone, sorry!”)
Izuku, of course, just smiled reassuredly and said it was no problem at all.
Now, just like puzzle pieces fitting together, Izuku started to taking care of the pups. First, he helped the two pups making sand-castles, but in an area where the sunlight didn’t directly come, otherwise, it would be bad for the pups—Izuku’s words, not his. Second, he brought them fruits and peeled them himself, all the while Katsuki simply stood there in amazement. Every time Izuku and the pups laughed together, Katsuki’s heart turned a somersault. Watching them together like this felt just right, like a scene taking out from a painting.
The little fuckers were genuinely loving Izuku too. Katsuki could tell.
“Ah, again, I’m so sorry!” Katsuki hears a voice say; when he turns around, he sees the mother approaching. “I hope they behaved well?” The woman says, standing in front of Izuku.
Izuku smiles bashfully, “They were great! It was nothing, really. They asked me to bring some fruits and I did, I hope that was okay?”
“Oh, you didn’t have to! But, thank you regardless.” The woman claps her hands, “Let’s go, kids!”
“B-But m-mom! I want to play with him more!” One of the pups says, and the other quickly agrees with him. “Me too!”
“We can play whenever you want to!” Izuku beams, “but now, I guess your mother has missed you.” Izuku underhandedly winks at their mother.
The pups walk along with their mother without further convincing, small pouts settling on their faces, and their mother whispering another ‘Thank you,’ behind their backs as they leave.
Katsuki kisses Izuku the moment he comes back, brushing his lips against Izuku’s, and remembering once again how lucky he is to have him.
“Mmm,” Izuku purrs, “what was that for?”
“I just… love you,” he speaks under his breath. I love you so goddamn much.
After Izuku came back, the utter fact Katsuki had fathomed was that he had a hard-on. Thus, the rest of the day was an absolute challenge to overcome. It is safe to say that the last thing Katsuki expected was to have a pup fever on their honeymoon; seeing Izuku like that did things to his heart, and evidently to his cock, his cock that was achingly rock hard and throbbing all day. The thought of getting Izuku pregnant invaded his mind; leaving no other argument in consideration.
Catching sights of pups running around didn’t help in the slightest, either. He couldn’t possibly stop thinking about pumping Izuku full of his cum to make sure that his Omega was bred. Katsuki wanted to see their pups running around and being useless cute fuckers! They were going to be the products of their love! as Izuku would say.
Katsuki knew that Izuku might have suspected of something, considering the case that him going to take a piss this often throughout the day, in reality to jack off to the idea of breeding Izuku to find some momentary relief.
Now, in their hotel suite, laying on their California King bed, his cock is getting hard again.
“Kacchan…” Izuku mumbles sleepily, feeling Katsuki’s erect cock up on his ass, “this is going to be our… ” he halts, “I lost the count.”
“So what?” Katsuki’s fingertips find Izuku’s aroused nipples, rolling the rose pink buds. “We are on our honeymoon.”
Izuku lets out a choking sound and turns around, kissing Katsuki and stroking his pulsing cock with one hand. “You’re going to carry me around if I can’t walk tomorrow,” he says with crossed eyes.
Katsuki smirks, “Gladly.”
Izuku reaches out for the drawer to get the condoms, but Katsuki interrupts him, “No condoms this time.”
“W-what?” Izuku stumbles, yet stops his hand mid-air nonetheless.
“You heard me the first time, Deku.” Katsuki’s voice is stern and firm. “No condoms.”
Katsuki takes Izuku under him; lowering himself, he plants little kisses on Izuku’s belly, “Gonna get you pregnant—” he growls, a sound that rumbles from the core of his chest, “gonna knock you up.”
“K-Kaccha—” Izuku falters, his beautiful green eyes growing wide.
This time, Katsuki ceases his movements and raises himself up to face Izuku, palming his cheek with his one hand. “Hey, hey—” Katsuki softly says, “Izuku. Look at me, baby.”
Izuku eases on the instant he hears Katsuki’s voice, looking at him straight. “I want to have a pup with you.” Katsuki whispers, kissing Izuku’s forehead before continuing, “and, I don’t want this to freak you out. You’re the love of my life, you know that. I don’t give a fuck if we’re newly married. Seeing you playing with pups today made me realize I don’t want to wait.”
Izuku smiles, one of his smiles that is too bright that even the sun pays homage to. “Kacchan, you’re the love of my life, too.” His freckles are tinted with a blush. “I want to do this.”
“Yeah?” Katsuki grins, caressing Izuku’s cheek with his fingers.
“Yes. Though, I need you to confess something.”
Katsuki frowns, confused.
“Is the reason why you went to the bathroom this much today is that you—u-uh…”
“Fucking hell, Deku. Yeah, you know everything, ain’t you? I got horny to the thought of breeding you. You are my wife.” Katsuki scowls, his eyebrows furrowing deeper.
Izuku giggles at Katsuki’s exasperation, “I just got the pieces together when you said the things about me playing with pups, Kacchan.”
Slowly, Izuku lifts himself up, parting his lips to meet Katsuki’s. His kisses are soft, yet so capturing, enthralling. Katsuki is the one who pushes his tongue to claim every inch of Izuku’s mouth, is the one who hastens the kiss. Katsuki’s kisses are hungry, as though someone will take Izuku away from him at any given moment (no one ever will; not when Katsuki is around. He would rip anyone’s head off for even daring to try).
“A-ah—” Izuku pulls back slightly to catch his breath. “Kacchan—” he moans.
“Yeah, baby. Keep saying my name. Say my name when I breed you; when I fill you up—Fuck!” Katsuki groans, positioning himself to thrust into Izuku.
Good thing that they were already naked, Katsuki notes. He certainly wouldn’t want to waste his time by removing their clothes off.
Pressing the tip against him, it takes no time for Katsuki to shove his whole length inside the encompassing warmth. The same warmth that intoxicates Katsuki and wraps around his cock.
“K-Kacchan!" Izuku whimpers, closing his eyes.
“Open your eyes, baby.” Katsuki purrs. “Look,” he growls, cupping the bulge that his cock carved out into Izuku. “That’s how you will look pregnant,” he says drunkenly, releasing a low, guttural noise.
Izuku opens his eyes to see the fat bulge. “Kacchan! Do it—please.”
“Do what, Deku? Use your words.”
Izuku licks his lips, green eyes hazy and dark. He breaths in, “Fuck me,” he breaths out, “Breed me.”
The air withdraws from Katsuki’s lungs. Without another word, Katsuki takes up the pace: he pulls out completely just to slam in again, reshaping Izuku’s insides, his huge length making its way through. Katsuki folds Izuku in half, pushing his legs up on his broad shoulders. Katsuki’s cock constantly stimulates Izuku’s prostate, whose eyes are heavy-lidded, and tears are running down on his flushed, red face.
He leaves bites on Izuku’s sensitive skin: next to the claim that he bared with his own fangs. Katsuki’s stubble chafes against the area with every motion of his face, and Izuku lets out a soft whimper; a little pain did not ever bother Izuku, after all. Izuku’s scent is enhanced; sweet and fresh, whereas Katsuki’s scent is heavy, woodsmoke and musky tones mixing in their surrounding.
“I will pup you, knock you up; so that everyone will know who you belong to— You are mine.” He fucks Izuku into the bed, pinning him down and claiming his mate’s being.
“I am. I am yours, Kacchan,” Izuku keens, squirming from overstimulation as Katsuki doesn’t take one second to slow down, constantly pumping in and out of his Omega
Turning Izuku’s face to the side, he takes another bite from his neck, Izuku might probably scold Katsuki later—when he is not completely fucked out of his mind—having these many bitemarks, but Katsuki cannot bring himself to care. He will mark his Omega as his, forming as many bites as he can.
When Katsuki touches the fat bulge that his cock made again, Izuku yelps by the sudden pressure.
He can’t help but be overcome by affection. Izuku looks absolutely ethereal: his supple lips are slightly open, his tongue is sticking out, and his face is wet from tears, eyes shimmering and needy. Katsuki kisses Izuku one more time, swallowing his weak moans as his tongue licks the corner of his mouth.
“Deku, do you have any idea how beautiful you look?” Katsuki asks, his eyes hooded with lust, and burning into Izuku’s teary ones. “My Omega.” He grinds between his teeth.
“Yes. Yes. Yours—only yours.” Izuku pleads, tugging Katsuki closer.
The scent mixed in the air tells it: their fire is rough and animalistic and entirely uncontrollable. Katsuki drills into Izuku’s heat, hammering his whole shaft in as his knot starts to catch up on Izuku’s abused hole. He wraps his hands around Katsuki’s neck, clinging to him for the life of his, and arches his back as his orgasm carries out; screaming out with whatever strength left in him and chanting Katsuki’s name.
“A-alpha!” Izuku sobs, “K-Kacchan… Katsuki—”
Izuku’s cum paints his belly white, a little of it splashes on his blushing face as Katsuki groans into Izuku’s neck, his knot is getting harder to pull out.
“Izuku! Fuck!” Katsuki moans, jolts of his thrusts getting frantic and intense.
One more thrust and he knots Izuku; plugging him on Katsuki, on his Alpha.
He dumps his heavy load into Izuku, pumping his cum deep in him, fucking his cum into him, and not letting a single drop escape. Filling Izuku up to the brim as his seed doesn’t stop stuffing Izuku, waves of cum settling far inside and rounding his belly up.
The realization that Izuku being bred makes him ecstatic. More than any kind of drug can, more than any kind of intoxicating substance can. Even when his knot deflates, he will pump Izuku with more, knot him more, and make his Omega walk around with a plug in his gorgeous ass so that not one drop will slip away.
Izuku, your Omega, is bred; his Alphan instinct says loud in his mind.
“Baby,” Katsuki calls quietly, his forehead touching Izuku’s.
He doesn’t answer, which makes Katsuki opens his eyes he hasn’t realized he closed to make sure Izuku is fine. “You okay?” he tries again.
“Mhmm… Kacchan—” Izuku hums.
“Shh,” Katsuki murmurs, “you don’t have to talk.”
“‘Can’t close my legs,” Izuku blurts out, and then he laughs; it is small and shaky, and it still makes Katsuki’s heart flutter.
Instantly, Katsuki looks down and, well, Izuku can’t close his legs, alright. His knot is fucking massive; popping up between Izuku’s legs and swelling his belly up.
“Fuck,” Katsuki curses under his breath.
“That’s okay.” Izuku silently says, wrapping his legs around Katsuki’s waist. “We’ll stay like this,” he pauses smirking, “until your stupid big knot deflates.”
Katsuki groans, burying his face down into the curve of Izuku’s collarbone and lapping his tongue around the new-made bites, he encircles Izuku’s hips and pulls him even closer.
“I love you,” Katsuki whispers.
“I love you too, Kacchan.” Izuku sighs, fingers tracing along the nape of Katsuki’s neck.
