Mating runs. Every omega’s chance to find their mate. The chance to find their soul mate and bring pups into the world. What goes around comes around, right? Izuku had just turned eighteen and thus it was his turn for his mating run. Most omegas look forward to this day, but for Izuku, he didn’t want this day to come, because for him, he already found the one he wanted to spend the rest of his life with and that was his best friend; Katsuki Bakugo.
Katsuki and Izuku have known each other since they were pups. Katsuki belonged to the Barbarian Bakugo clan, the next village over, the “prince” of Mitsuki and Masaru Bakugo. Izuku was the son of Inko and Toshinori Yori, the leaders of his clan. Izuku and Bakugo had always said they were destined to be together, “fated mates” their parents had said, but when the council of elders of Izuku’s village had decreed that Izuku had to participate in the mating run, Izuku was heartbroken, and the worst thing? Katsuki wasn’t allowed to participate because Katsuki wasn’t of age yet. The council knew Izuku was the most desirable omega, and that this mating run would be the best of the best. All the most prominent alphas around their settlement would be participating, vying for Izuku’s attention.
Izuku was in the dressing room, the elders getting him dressed in the ceremonial mating run garbs, traditional for the children of the leaders of the clan. The garment left nothing to the imagination, as it was custom to be mated immediately after the mating run, and the less clothes got in the way the better. Izuku’s inner omega was screaming because it didn’t want anyone but Katsuki.
Where’s our alpha?
Alpha is our mate!
No one can touch us but our Alpha.
Izuku tried to calm the inner omega within him, but he too knew he didn’t want anyone mating him but Katsuki, he had spent his whole life preparing for the moment that they would be mated.
Izuku’s outfit consisted of a deep, emerald, green gown, with gold and ruby accents around the neck. It was almost see-through, made of the most delicate lace. Around his neck he wore a pendant that was custom of the village, a talisman that brought good luck and fertility for his future mate. It was hand crafted by the elder woman of the village, it was inlayed with emeralds and had tiny, crimson-colored gems. Izuku took one look at it and was reminded of Katsuki. The red against the green. Crimson eyes and forest green, together like they should be. Izuke whined, needing his alpha to hold him close, to be able to smell his burnt caramel and cinnamon.
After the elders had finished dressing him, they started rubbing lotion on him made up of several different flowers and herbs that were used to induce his heat, making it easier for the alphas to pick up on his trail and chase after him. Izuku never knew what went into the concoction, only that it was highly potent and worked fairly quickly. By the time the elders left, Izuku could already feel his body starting to warm, and slick started running down his legs. Izuku desperately wanted to touch himself, but the sound of a horn brought him back, and it was the signal for him to take his spot for the mating run to begin, to stand with the other omegas that would be in attendance.
Izuku took his place, looking around at the other omegas in attendance from the other villages. Some of them he recognized, others he didn’t.
By the time the horn sounded, Izuku could barely run, his heat becoming so powerful at this point. He took off, his inner omega begging to be knotted by their alpha. Izuku at this point was releasing mating pheromones, drawing in several alphas. The sun was starting to set over the horizon, the beasts had been released, and Izuku felt like prey being hunted for sport.
Izuku was running through the woods, ducking under branches, jumping over overturned logs, and stumbling several times. He could almost feel the breath of several alphas that were hot on his tail, growls coming out of their mouths, almost fighting each other for the chance to mate with him. When Izuku came to a clearing, his heart stopped and his nose was assaulted with burnt caramel and cinnamon, and then his eyes met crimson and he stopped and fell into the mud. His inner omega chirped.
It’s our alpha!
Our alpha came to find us! His inner omega whined.
The other alphas made it to the clearing and looked down to see Izuku face first in the mud, in perfect presenting position, but what they didn’t know, was that Izuku was in this position for an alpha that they hadn’t registered yet.
“There’s the pretty omega,” one of the alphas sneered.
Izuku’s inner omega growled.
“He’s in the perfect position for us,” another one chuffed.
Izuku could feel the slick running down his legs, and while Izuku was disgusted with the idea of these alphas taking him, his body and his mind were on different wavelengths.
“Who says just one of us has to have him, why don’t we all share, and better yet, we don’t have to mate with him, we can just fuck him and leave.” One of the alphas sneered.
Izukus heart dropped. And then he heard it, a growl he recognized immediately, one that caused the other alphas to snap their focus to the crimson-eyed blond in front of them.
“You bastards keep your filthy cocks away from him,” Katsuki snarled. Izuku’s inner omega was preening.
Our alpha will protect us!
The other alphas froze; their whole bodies tense. They had never met an alpha so commanding before, and it brought fear to their eyes. See what these shitty little alphas didn’t know, was that Katsuki was a True Alpha, it meant he ranked above all others, and while alphas aren’t influenced by other alphas commands, with Katsuki it was different, being a True Alpha, he could command anyone.
“Get the fuck out of my sight before I rip you to shreds,” he commanded.
The other alphas didn’t say anything; they just turned around and ran. Before Izuku could say anything, Katsuki spoke up.
“There’s nowhere to run omega, come here right now.” It wasn’t a command, Izuku could choose to ignore it if he wanted to, but he wanted Katsuki, he needed Katsuki.
Izuku stood up and wobbled over to Katsuki; his heat had kicked into full gear now, and he no longer had control of the heat pheromones he was releasing. He could see Katsuki’s blown out pupils, could see him fighting every urge to fuck him right then and there. One look from Katsuki and he knew Katsuki was his and he was Katsuki’s.
He almost fell again and Katsuki caught him this time.
“What are you doing here Kacchan, the elders forbid you from being here.” Izuku breathed out.
“Tch.” Katsuki scoffed.
“Like some dumb rules are going to keep me from seeing and mating with my fated mate.”
Izuku’s inner omega trilled at Katsuki’s words.
“I didn’t want this Kacchan, I didn’t want anyone else, I only wanted you.” Izuku whispered.
Izuku could hear Katsuki’s alpha purring.
“You’re mine Izuku, and no one is taking you away from me.” The words felt out of Katsuki so easily, like he had been waiting his whole life for this moment, and secretly, Izuku has been dying to hear those words as well.
Izuku started to purr loudly against Katsuki’s chest, and he could hear Katsuki crooning.
Katsuki scooped Izuku in his arms and ran. He kept running until they made it to a makeshift hut, one the boys had been running to since they were pups. Katsuki pushed open the door and carried Izuku to the mess of blankets and pillows in the center of the room. He set him down and Izuku whined.
“Alpha, please, I need you,” Izuku begged.
Katsuki groaned and his alpha purred.
“That’s right omega, beg for your alpha, tell me what you want.” Katsuki soothed.
Izuki was a mumbling mess. His body was hot all over; he could barely form coherent thoughts. He couldn’t even bring himself to say what he wanted.
“Clothes,” was all Izuku managed to breathe out. And thank fuck, Katsuki knew what he meant. Katsuki shredded the clothes Izuku was wearing, and he was naked before Katsuki, his fated mate.
Izuku squirmed underneath Katsuki’s intense gaze. His little omega cock was rock hard against his abdomen, leaking profusely. Slick was pouring out of his hole.
“Fuck ‘Zu, you’re dripping for me.” Katsuki groaned.
Izuku whined. He just wanted, no needed Katsuki to touch him. He knew he would feel better if Katsuki touched him.
“Alpha, touch me, please!” Izuku whined out.
“My sexy omega, begging for his alpha to touch him.” Katsuki teased.
Wasting no time, Katsuk’s hands started roaming over Izuku’s and felt like electricity was coursing through him. His body was on fire, and Katsuki’s touch was the water to quell the flame.
Katsuki leaned his head down against Izuku’s scent gland, licking and sucking on it. He could feel the alphas fangs grazing it. He never wanted anything more in his life than to be mated to his alpha, his best friend, his one true and fated mate. He could hear Katsuki’s rapid heartbeat and his heaving breaths against his ear. Katsuki’s hands were all over his body, his lips everywhere, painting him like Izuku was his canvass.
“Turn around and present for me omega, give me what I like,” Katsuki commanded.
Izuku immediately turned around and stuck his ass in the air, his torso lowered, head in his arms, in the presenting position. His neck is on full display, ready to be bitten, ready to be mated.
Katsuki slapped Izuku’s ass, causing Izuku to groan and a fresh wave a slick to come out of his hole.
“Fuck ‘Zu, you like that? You little masochist.” Katsuki growled.
Izuku’s inner omega was preening, soaking up the praise from their alpha.
“Y-yes a-lpha,” Izuku stuttered.
Katsuki spread Izuki’s ass cheeks apart, sticking his tongue out and licking up Izuku’s hole. His hole twitched at the touch. Katsuki stuck his tongue into Izuku’s hole, circling around the inside, prodding his insides.
Izuku moaned out, his insides being assaulted by Katsuki’s tongue. His cock was hard and begging to be touched, not to mention how much it was leaking. Izuku shoved his ass back, begging for more.
“K-kacchan, d-don't s-stop, p-please,” Izuku begged.
Katsuki purred into Izuku’s hole, his inner alpha loving the begging from their omega. Katsuki stuck a finger inside Izuku’s hole alongside his tongue, opening him up, preparing him for the knot he would be getting later.
Katsuki was addicted to the taste of the slick pouring out of Izuku. It was sweet, like chocolate, and he knew they were meant for each other, that Izuku was made just for him. Katsuki continued to assault Izuku’s hole with his tongue and finger, his own cock aching to knot his omega’s hole. He could feel Izuku getting lost under him. He was panting and drooling into the pillows under him, muttering curse words, begging Katsuki for more. He was being so filthy, and Katsuki was so turned on.
Katsuki felt Izuku’s ass clinch around his tongue and finger as Izuku moaned and shuttered through an orgasm without even touching himself. Katsuki pulled away, a line of spit coming from his lips to Izuku’s pulsing taint. He licked his lips, savoring the sweet taste from the slick.
“Fuck ‘Zu, did you just cum from me rimming you?” Katsuki moaned.
Izuku flushed as red as a tomato and hid his head in the pillows.
“Shut up Kacchan!” He whined.
Katsuki bent down and licked the back of Izuku’s neck, his fangs leaking venom, his inner alpha begging him to mate.
Mate him! Knot him! The omega wants us!
Izuku’s inner omega was mewling, desperate for their alpha to mate them. Izuku’s body was hot, the rimming wasn’t enough, he needed more.
“Knot me alpha, please,” Izukue begged.
Katsuki groaned, his cock pulsing. He pulled away from Izuku’s neck, spreading his hole open once again. He lined his cock up, gently inserting the tip in, Izuku’s hole sucking him in, begging to be filled. Katsuki threw his head back and groaned.
“Zu, your hole is practically begging to be filled, sucking me in.” Katsuki purred out.
A fresh wave of slick coated Katsuki’s cock, leaking out of Izuku’s ass and dribbling down his legs. Katsuki’s cock pulsed from the fresh warmth of the slick. He slid further into Izuku, inch by inch until he bottomed out against Izuku’s ass, his pelvis touching Izuku’s ass cheeks.
“I swear to god Kacchan, if you don’t start moving, I’m going to go insane.” Izuku growled out.
Katsuki stilled, his inner alpha proud of his defiant omega. Katsuki’s heart fluttered. He drew his cock back until just the tip remained, and then he slammed back in. Katsuki reached his hand down and wrapped his palm around the back of Izuku’s neck, pushing him into the pillows. He could feel Izuku shove his ass back in time with Katsuki’s thrusts.
“Don’t tell me what to do you sexy minx, I’m the alpha here, not you, you don’t get to command me,” and with Katsuki's other free hand he slapped one of Izuku’s ass cheeks, hard. Izuku groaned from the spanking and his little omega cock twitched. Katsuki smirked.
“You like that you dirty slut? You like when your alpha spanks you for being a bad boy?” Katsuki teased.
Izuku sputtered. His ass twitching from the assault of Katsuki’s palm smacking his ass. He nodded his head, unable to answer him. Katsuki growled and grabbed a fistful of Izuku’s hair and yanked his head up.
“Answer me omega!” Katsuki snarled.
Izuku moaned. He loved being man-handled. He loved being slapped. He loved it when his alpha was so domineering.
“Y-yes alpha,” he sputtered.
Katsuki chuckled. He kissed Izuku passionately, shoving his tongue down Izuku’s throat. His fangs bit Izuku’s lower lip, drawing blood and Katsuki could taste iron. His fangs were dripping venom. He pulled away from Izuku’s mouth.
“Good boy, such a good little slut for you alpha,” Katsuki praised.
Katsuki shoved Izuku’s head back into the pillows and continued fucking into Izuku with reckless abandon. He could feel his knot starting to swell, slapping against Izuku’s ass, trying to get in.
“Knot me alpha, please, please, please!” Izuku begged him. Katsuki growled and shoved his knot past Izuku’s tight ring and Izuku came immediately. Katsuki pumped into him a few more times until he shot his seed, fulling up Izuku, knowing he was being pupped, and he bit into the back of Izuku’s neck, releasing his venom and creating the bond. He could feel everything Izuku felt at that moment, the love, the yearning Izuku had felt all these years, and his alpha was over the moon at finally being mated to the one they were destined to be with.
Katsuki and Izuku collapsed onto the mess of pillows and blankets. Heavy breathing between the two of them. Sweat pouring down their bodies. Katsuki could feel Izuku licking his scent glands, fangs on display, wanting to leave a bite mark on him as well.
“Bite me omega, make me yours.” And Izuku did, biting into Katsuki’s scent gland, releasing his venom, sealing their bond.
Izuku’s body was no longer hot; the bond had been formed, and he had been knotted. He was so glad how the evening turned out and was glad that his alpha had been the one to breed him.
And if nine months later there were a set of twins that were born, one; a sweet girl with green hair and crimson eyes, and a fiery blond boy with green eyes, well Izuku wasn’t going to complain.
Nowhere to run boy run come here right now, right now, come here right now
