Katsuki walks back to his cave from a long trip with his guild. They had gone to a ruined town, recently taken over by a horde of out of control monsters. They had scavenged the village for survivors and found none, the monsters having left as well. He missed the comfort of his home after a week of travel, and he desperately wanted to take a long shower. He also missed the people he had left behind on his trip, and he wanted to feel, their warm embrace.
He walked into the entrance of his cave, surprised at how dark it was. They had usually cared to keep the lights on. He guided himself through the cave, using four strangely floating lights, two lights red and the others silver. Once he finds the light, he turns it on, gasping at the sight before him. One large red dragon with sleek scales and piercing red eyed stared at him. Another, silver, lizard like creature with rugged scales and silver eyes stared at him as well. He let out a harsh breath fear still buzzing under his skin. “Why are you guys staring at me? You scared the shit out of me.” He went and sat down a basket of fruit he had brought for his hybrids, and when he turned back around, his pets were in half human form, still staring.
They were on him in seconds, Kirishima burying his head in the man’s hair, and Tetsutetsu burying his head in the man’s neck. “Come on you guys, it was only a week.” They ignored him, pressing kisses into any area of open skin they could find. Sounds of breathing and growls filled the cave as the two men pushed their smaller lover to the nest. Kirishima and Tetsutetsu towered over the other man, both standing at over 8 feet. Being hybrids of their stature, they had firm muscles and long limbs, tribal tattoos running up their thick arms. Katsuki on the other hand, was a five foot five wolf hybrid, with a small frame and soft features. He’s tried hard to build at least some muscle mass, but he could only get so far.
As an omega, he was born to be a petite wife for some big shot in his village. But he’s never wanted that, trying hard to put out a horrible personality, making sure alpha’s stayed away. But he could only run from his fate for so long. He remembered the moment like it was yesterday. Waking up to the smell of warm breakfast cooking, only to find his parents and a strange man sitting at the table. They informed him that he was getting married in two days, wether he likes it or not. It didn’t matter how loud he screamed or how much shit he threw, his parents wouldn’t change their mind. So he ran. He ran to the depths of the forest into a den of feral snakes hybrids. They were shifted into their snake forms, which happened to be at least ten times the size of the man. He was trapped in their coils in seconds, life quickly draining from him. The last thing he saw before he passed out, was a flash of red.
When he’d awoke, it was to the embrace of a dragon. He lay against warm scales, curled into the smooth and enormous body. He’d quickly got up, shifting into his wolf form and snarling at the dragon. That awoke the beast, his red eyes flying open. Once he surveys his den and see’s that there’s no threat, he shifted into his human form, relaxing back into his nest. “Good morning,” he’d said. “I’m happy that your awake.”katsuki stops snarling, but the hairs on his back are still raised, not knowing why the man had kidnapped him. “Oh it’s okay puppy,” the man smiled. “I took you here cause you’d wandered into a nest of Ridgehead snakes. I brought you back to my den so you would feel better. Though, you still smell distressed, you smelled this way when I found you too. What’s wrong pup?” Katsuki slowly let’s down his guard, not smelling any animosity coming from the man. He changes back to his human form and walks over to the man.
“Your an alpha, huh?” He’d said. The dragon nodded. “My parents, they arranged a marriage with me and some meat headed alpha. I could smell the fact that all he wanted was to fuck me. And I didn’t want that. So I ran away. I didn’t mean to intrude on your den though. I’ve heard stories of how protective you dragons are of them.” The older just let out a rough sound from the back of his throat. “I don’t mind. I’ve been searching for someone to share my den in for a while. Plus, I let you sleep in my nest. Your not intruding at all.” Katsuki is too tired to argue, letting his omegan side take over as he sinks into the alphas open arms. And katsuki stayed with the man, bringing him back food and keeping him satisfied. And when he found a new guild a couple mounts later, it was opportunity for him to travel to new places, finding new things for his alpha to enjoy. It was on a trip when he met Tetsu. The man was passed out in his human form in the middle of the woods. Katsuki never did know why he felt compelled to take the man to his den, but he did. And Tetsu smoothly fell into their dynamic, warming the nest with an extra body. Taking up Katsuki’s neck with another bite mark.
The same bite marks that were being traced over by Tetsu’s forked tongue right now. He sighed in pleasure as the marks throbbed under all the attention, melting into his alphas arms. “We missed you so much baby,” Tetsu growls as he flips the boy around so that he’s spread out over him and Kiri’s laps. A hand massaging his ears has him letting out an embarrassing moan as he sinks into his lovers’ touch. “We were worried that you weren’t gonna be home in time.” The feeling of three hard cocks rubbing against his ass almost make him ignore the words that left his alphas lips. “Missed what,” he says with a breathy moan. Kirishima chuckles above him, hand running up and down the smaller man’s hips. “Our ruts baby. They started today.” Katsuki moans, grinding his ass harshly on the two below him. “Fuck Kiri, your serious?” He questions them, but their slit pupils and hungry expressions leave no doubt in his mind. He’s dealing with alphas in rut.
His alphas make light work of tearing him out of his outfit, leaving him exposed in the cold air. They growl at the sight of his chubby wet cunt on display, Tetsu moving back to the ground in front of katsuki, squishing him between his large frame and Eijirou’s. He leans down to lick the juices from the man, groaning at the boys sweetness. “Fuck you taste so good baby. I can’t wait to stick my cock in you.” Katsuki moans, throwing his arm over his eyes, trying to hide from the pleasure he was receiving.Tetsu worked open his pussy with his tongue while Kiri began to run a cold, lubed finger up and down his ass. He squirmed and whined as his cunt and ass were stimulated, knowing that this was just the beginning of a long night of hard sex. He gasped as Tetsu’s tail slipped inside of him, mouth moving to his clit, sucking hard and giving tiny bites to the sensitive bud. He whined as the tail went deeper into him, getting thicker as it went further in. He moaned loudly as he was stretched open from both sides. Kirishima worked a fourth finger into him, bringing Katsuki to his first orgasm.
His alphas groan as they both pull out, Tetsu taking his cock out and beginning to stroke it. Tetsu was massive, nine and a half inches of thick length ready to fuck into his lover. Tetsu’s cock was different that the alphas at his old village. It was thick at the base, like normal, but the tip was more like a tentacle, easy to slip inside of him. ”Fuck Katsuki, look at your cunt, drooling at the sight of my fat cock. Let me put it in darling please, you smell so fucking good.” Katsuki just moaned, not even noticing the scent of arousal he was letting out. He nodded at the man’s words, needing to fill the fullness of his cock. “Please alpha, I need you.” The second the words left his lips, Tetsu was thrusting Into the smaller man, groaning at the feeling of the man’s tight cunt around his cock. Katsuki let out a high pitched whine, moaning as he got his cunt fucked into. Beneath him, Kirishima lines himself up to Katsuki’s entrance, slowly sliding into him. Katsuki almost screams at the dual pleasure he was experiencing. His moans turn sloppy and incoherent as he’s pounded from both sides. “K-kiri,” he sobs loudly, “take one out, p-please.” He whines as the man chuckle deeply below him. “I’ve only put one in baby. But I don’t know how long I can wait to put both in, I just want to fill you up so fucking bad.” Katsuki moans pitifully as Tetsu begins to moan on top of him, thrusting harder as he got quicker to his orgasm.
“F-fuck baby, i don’t think that I can hold out much longer.” Tetsu growls loudly slamming his cock inside the boy for one final thrust as he cums into the boy. He hadn’t even knotted Katsuki yet, but he pumped enough cum into the man that it didnt matter. Warmth flooded Katsuki’s tummy as he came again, clenching onto both the cocks buried inside of him. Kirishima groans from below him, pulling his cock from the boys ass. “Fuck Kat, I need to put both in. Lemme fuck your cunt baby ,please.” Katsuki just moans and nods as Kiri manhandles him and turns him around. Kiri doesn’t sit Katsuki on his cock, he first admires the boys fucked out expression. Wet eyelashes and flushed cheeks, lips moist as he drooled for Kiri’s cock. But his eyes were quickly drawn to the smaller man’s pussy, Tetsu’s cum beginning to drip the boys cunt. He groaned as he dropped the man onto his cock, using pure strength to bounce the boy up and down his cock. Tetsu, not wanting to miss out on the pleasure, quickly lined himself up with Katsuki’s ass, letting Eijirou do the work of moving Katsuki.
Katsuki was a fucked out mess, orgasms ripping through him every couple of minutes. His alphas however, didn’t stop, using him and his dripping cunt like a fuck doll. As another shaking orgasm ripped through him, his body going limp between his men. He was ready to just relax and let his alphas keep fucking him when he feels something line up with his cunt. He whines, feeling his pussy stretch in a way that borders on pain and pleasure. “E-Ei please it’s too much,” he cries as he gets split open on the man’s cocks. “No Ei stop, it’s not gonna fit. Your too big alpha, please!” Kirishima just growls, continuing to bury his second cock in Katsuki’s fucked out cunt. Katsuki panted at the intrusion, letting out soft whines as Tetsu and Kiri thrusted softly into the man’s pussy. “Such a perfect omega,” Kirishima growls out. “I just wanna fuck your full of my hatchlings.” Katsuki moans loudly, hips grinding at his alphas words. “Fuck, you like that baby. The idea of getting filled with me and Tetsu’s kin. Just staying in the nest and taking care of our kids?” Katsuki nodded, eyes brimming with tears. “Yes, yes, yes!” He exclaims suddenly. “I want you and Tetsu to fill me up with your hatchlings. Make me pregnant Ei, please Tetsu!”
He groaned again as he felt the base of Kiri’s cocks begin to swell, the man approaching his orgasm. “Fuck Kat, ‘m gonna pump you full of hatchlings. Wanna see your cute little tummy expand with my kin.” Katsuki just whines, allowing Kirishima cocks to fuck him impossibly harder. He’s starting to get concerned for his cunt, because kiri’s cocks are still swelling, the swelling starting to move up the length of his dicks. “W-wait Kiri!” The man just thrusts harder, burying his cocks in the boys cunt. Katsuki screams, eyes rolling to the back of his head as something foreign is pumped into his cunt. They’re smooth and firm, at least the size of a grapefruit. He sobbed as three of them lodged themselves in his wrecked pussy, the deepest one kissing his cervix. His eyes cross as his alpha bites into his shoulder, warm cum being pumped into him as well.
Tetsu groaned from behind him, hand going down to rub Katsuki’s swollen belly. “Fuck Kat, you look almost pregnant. I wanna pump you even fuller with my cum baby.” Katsuki just nodded, drool coating his lips and tears streaking his face. “Breed me sir,” he moans. That’s all it takes for Tetsu to slip out his ass and shove his cock in his cunt, Kiri having already pulled out. He can only moan at the man’s thick length. Fucking the eggs deeper into his cunt. “Baby I’m so fucking close.” Katsuki can barely hear the man over the fog settling in his brain. “‘M gonna pump you full of my hatchlings. Such a perfect omega, carrying our kin.” Katsuki keens at his words, feeling the alpha’s cock swells, similarly to Kirishimas. “Fuck baby im cumming,” Tetsu exclaims, pumping two more eggs into Katsuki’s cunt. Katsuki screams as he feels Tetsu bite into his other shoulder. And that’s the last thing he feels before he passes out.
“Morning sweetheart,” kiri greets, running through Katsuki’s hair with his fingers. Katsuki can only groan, letting himself relax into the scalp massage. “How are you feeling? That was kinda intense.” Katsuki looks down at his stomach, a clear bulge apparent from all the eggs stuffed in him. “What the fuck is this,” he questions, words not as harsh sounding since he was still waking up. “Our eggs,” kiri says with a blush. Katsuki blushes. Running his hand over his tummy. “Does that mean I’m pregnant,” he questions, fascinated with his new belly. “Yeah,” kiri blushes. “But you don’t have to be of you don’t want. The eggs are pretty easy to remove up to two months after impregnating. They would be laid a month after that and then cared after for another few months until they hatch.” Katsuki just nods eyeing his other, silver haired, sleeping alpha. “I know we didn’t talk about this so I’d understand if you don’t wanna keep them. I’m sure Tetsu would understand as well.” Katsuki just scoffed. “What are you saying I’m too weak to be a mom. Fuck you, I’m gonna make pregnancy my bitch.” Kirishima just laughed, waking up a confused Tetsutetsu.
“Thank you baby.”
