Chapter Text
There weren't many omegas at school with Megumi Gojo notes as he drops his precious Megumi off on the first day of classes. " Are you sure I can't walk you in? You never know who'll try to sniff around an Omega like you." Gojo holds his hand and squeezes it firmly. He can smell a lot of alphas close by and his instincts go into high alert. He's only had Megumi less than a year now and he'd be damned if something happened to him on the very first day.
" I'll kick their butt if they try." Megumi says confidently and Gojo snorts because he knows that for a fact. Megum i 's always been tough and stubborn, two traits he appreciates in Megumi. It means Gojo doesn't have to worry as much. He's been starting to think of Megumi as a member of his pack. Although it's taboo to consider an adopted pup your own blood Gojo doesn't care about tradition.
Heck his phone background has been Megumi and Tsumiki for over a month now. Suguru is tired of Gojo's gushing already but Suguru seemed to be tired of everything recently. "My big boy is going to school! All grown up!" Gojo hugs him tightly and lifts Megumi off the ground spinning around once before putting him back down. Megumi whines but smiles. "Do you have everything?" Gojo looks over Megumi's backpack. "Lunch? Water bottle? Your extra scent blockers?"
"Yes, yes, yes." Megumi nods with each question.
"Okay you're all ready. Now go make friends okay?" Gojo ruffles his hair and pushes him forward into the open arms of society. Hopefully he doesn't get eaten alive. "Love you Gumi-pie." He waves at Megumi when he turns to look back at him one last time before stepping through the gates. Gojo makes sure to stay until he can no longer see Megumi anymore. He's been fretting over this moment for months. Not having Megumi attached to his hip sounds like hell on Earth to Gojo but it's inevitable. As long as he stays away from other alphas he should be fine.
He hasn't noticed the omega trailing after him yet.
"G-Good morning." A soft voice speaks up behind him and he jumps. He'd thought he was alone but apparently he was wrong.
Turning he comes face to face with an adorable looking little pink haired omega. His eyes are bright red and sparkling despite the early hour. He's a bit chubby like most omegas tend to be which pleases Gojo since he loves cuddling. Gojo looks around hoping he wasn't talking to him but there's nobody else in sight. "Me?"
"Yes sir." The young boy bows respectfully at the waist and his scent wafts over Gojo. He smells like peaches and sugar and something spicy Gojo can't quite place. It's mouthwatering.
"Oh, good morning." Gojo greets back politely. "Is there something I can help you with?"
"Umm..." The little one fidgets nervously with his backpack strap and Gojo's heart melts a little bit. "My name is Yuuji Itadori, nice to meet you."
"Nice to meet you too Yuuji." The omega beams when Gojo says this making him chuckle. This kid is so cute and sweet he wants to squish his cheeks or something. But that would be weird and inappropriate so he doesn't. "What can I do for you?" Gojo repeats himself. There's no way he came to talk to Gojo without a reason right? Maybe he wants to ask for directions or something.
Yuuji's eyes flicker over Gojo's frame, up and down then back again. It seems like he's trying to make up his mind on something before his lips purse in determination. "I-If it isn't any trouble...would you be my mate?"
Gojo's jaw drops open comically as he stares at the omega with wide eyes under his sunglasses . Did...Did he hear that correctly? Surely not, right? He must've heard it wrong. There's no way this little boy just said what he thinks he did.
" What ?" He manages to say after a few seconds.
"M-My mate..." Yuuji stutters again looking down at his feet. His cheeks turn bright cherry red and he starts sweating nervously. His scent becomes sour with anxiety but he continues to speak. He's clearly nervous about this but he's determined nonetheless. Gojo's impressed by this. "Would you b-be m-my alpha?" He whispers so soft that even Gojo almost misses it but he hears every word. "My grandpa is very sick and he needs me to find a suitable mate so he won't worry about me. I don't know much about courting but," Yuuji looks through his bag before pulling out a small envelope and holding it out for Gojo to take. Gojo does slowly taking note of how much his hands shake as he offers him the gift. Gojo opens it and sees a card made of paper inside. It's covered in hearts with a picture drawn on the front. In messy scrawl it reads: Will you be my mate? Yes? No? ♥️
"That's really sweet of you." Gojo says sincerely while handing it back to him. He's honestly touched by his gesture but it doesn't change the fact that Yuuji is a kid and Gojo is an adult. "But you shouldn't go around offering yourself to people you don't know, okay?" He tells Yuuji as he ruffles the top of his head fondly.
"But you're different from other alphas..." Yuuji insists. "And my grandpa said I should only ask someone special. I think you're very special."
Gojo blushes slightly before laughing awkwardly. How can someone this cute even exist? It's like God put all their good looks into this little guy and forgot everyone else. Gojo can't believe how adorable Yuuji looks when he's trying hard to convince him that he'd be a good omega for him. If he wasn't so young he would've accepted immediately. Gojo has to give it to Yuuji though he is definitely charming and persuasive for his age. He has no doubt in his mind that once Yuuji hits his teen years he's gonna be breaking hearts left and right.
" You shouldn't ask alphas these things. You'll be swooped up in an instant by some creep." Gojo warns. "Promise me you won't ask anyone else?"
"...I promise." Yuuji nods. He sounds sad but resigned to the fact he was rejected by the one person he wanted.
"Good boy." Gojo praises and Yuuji preens under the compliment. He leans into Gojo's palm unconsciously and purrs softly. Gojo smiles at the sound before pulling away. "Now hurry along. You wouldn't want to be late on your first day now would you?"
Yuuji nods.
***
Yuuji is there the next day with flowers for Gojo, and then again after that bringing Gojo candy. He tries to ignore Yuuji as best he can, but Yuuji is so damn persistent that it becomes impossible. Every day without fail Yuuji comes running up to Gojo after Megumi leaves for class. He greets Gojo happily and hands over the gift of the day. He asks Gojo if he'll be his alpha again and every day Gojo declines him politely.
"I'm too old for ya, kid." He says as he ruffles Yuuji's hair affectionately. Yuuji leans into the petting like a cat wanting more. He whimpers sadly when Gojo stops.
" Other alphas hit me and call me names. You're so nice." Yuuji pouts. "I want an alpha that won't hurt me." He confesses quietly and Gogo's heart breaks. "Please, will you accept me as yours? I promise to be a good omega for you." He pleads with those beautiful hazel eyes staring directly into Gojo's soul.
"And what would happen if I said yes? Hmm? Do you really want to be mated to a man twice your age?" Goj o challenges.
Yuuji bites his bottom lip anxiously. He looks unsure of himself for a second but it quickly passes before Gojo can blink. Then he nods vigorously causing his hair to bounce wildly around his shoulders. "Yes! I'll be happy if you're my alpha!"
The sincerity of his response makes Gojo smile. Yuuji is such a pure boy and Gojo wants nothing more than to wrap his arms around him and hug him tightly. He looks so cute in his school uniforms . His eyes sparkle brightly whenever he looks at Gojo like he hung up the sun in his sky . He pulls on Gojo's arm and Gojo bends down.
Yuuji kisses his cheek.
Gojo blanks out for a moment as his brain processes Yuuji's actions. When he realizes Yuuji kissed him, really kissed him, Gojo freezes. He doesn't know what to say or do. He can feel a warm blush spreading across his cheeks while his heart beats rapidly within his ribs. Yuuji giggles before hugging Gojo tightly and burying his face into Gojo's neck. He rubs himself all over Gojo's clothes and Gojo can smell his sweet scent mixing with his own. Yuuji's scent smells stronger and sweeter than it did yesterday. He smells like honey and strawberries now with a hint spice to it that sends a tingle through Gojo.
"I can cook and clean and do everything an alpha expects from their mate, I promise you. Please let me prove it to you!" Yuuji exclaims happily and Gojo sighs. Yuuji really knows how to make it hard to say no to him. Yuuji leans close and whispers something else. "I can even give you babies if you'd like."
Gojo nearly chokes on his tongue when he hears this. He looks at Yuuji incredulously and sees the boy smiling innocently like he didn't just offer to get pregnant and birth his children. The sick thing is...that's not abnormal. Children become pregnant on the daily. Omegas were pulled out of school young all the time and sold off into the brothels and the markets. They're raped daily, beaten mercilessly, starved and dehydrated until all the fight leaves them. Once they break completely they're sent off to be sold to the highest bidder who can afford them. Gojo's stomach twists unpleasantly at the thought of Yuuji in such conditions.
Yuuji deserves better, much better. Gojo knows that for sure .
Still, it doesn't mean he can accept him either. He's still too young to understand what he's offering Gojo and he doesn't think it's right to agree. Even if he is tempted beyond belief by him. Even if with everyday he's breaking down Gojo's defenses bit by tiny bit.
Gojo is actually starting to like the idea of having Yuuji as his omega. He's so cute and sweet. He's got the kindest soul Gojo thinks he's ever seen. And that smile? That gorgeous radiant smile lights up the whole world and warms Gojo from the inside out. Gojo loves hearing Yuuji laugh. He's never heard anything sweeter.
Gojo never though he'd be one of those alphas into kids, but he guesses it's true what they say. Love finds you where you least expect it. And Gojo is falling fast.
"Yuuji...you're so young. You don't really know what you're asking me." Gojo tells him softly as he strokes Yuuji's cheek gently. "You deserve an alpha your own age who will cherish and spoil you. Someone that can give you everything you need. Everything you want..."
"I only want you." Yuuji whispers against Gojo's lips. "I don't know why but I can't stop thinking of you. When we met the other day, I knew I was meant to be yours." Gojo shivers at the confession. Yuuji has no clue what he means saying these things. He has no clue how his words affect Gojo. He's innocent in the worst way possible and it drives Gojo wild because it's so wrong and taboo.
Is this a case of fate? Destiny? Or is it simply hormones and biology playing tricks on both of them? Either way, Gojo wants Yuuji more than he should.
"Yuuji..." Gojo groans when the little omega presses closer to him nuzzling into Gojo's throat inhaling deeply as if trying to memorize his scent. His body is so small and warm against his and Gojo wraps his arms around Yuuji without a second thought. "This is wrong." He breathes out shakily while Yuuji licks over the spot where a mating bite would go if they were bonded. "I shouldn't be touching you like this. You're just a baby. You don't even know what you're doing to me. What am I doing?" He mutters to himself.
Gojo has to push him away. He can't let Yuuji continue this madness any further. He's gotta put a stop to it now. He has to. But Yuuji feels too good wrapped around him. His scent is intoxicating and addictive and Gojo is powerless to resist.
"Yuuji, stop please." He pleads but it falls on deaf ears.
Yuuji doesn't listen to him. Instead he continues licking and sucking at Gojo's neck like he's starving for the contact. Like he wants to mark Gojo for everyone to see. He wants to claim him as his alpha. His teeth graze over Gojo's skin sending jolts of pleasure through him. He shudders when those little fangs nip at his sensitive skin playfully.
Gojo can't help himself anymore. His self-control snaps completely . He grabs Yuuji by the back of his neck forcing him away from his throat before crashing their mouths together. Yuuji gasps loudly before melting into it immediately, kissing Gojo back enthusiastically. Gojo licks along the seam of Yuuji's mouth begging entry and Yuuji allows him inside eagerly. Their tongues tangle together as Gojo explores every inch of Yuuji's mouth. He tastes sweet like honeydew. He moans into the kiss while Yuuji whimpers helplessly. He clutches onto Gojo's shirt for dear life.
Gojo breaks off the kiss leaving them both breathless. He looks down at Yuuji seeing his flushed face and swollen red lips. Yuuji looks absolutely wrecked and they haven't even done anything yet.
"Yuuji." Gojo says his voice deep and husky. Yuuji whines low in his throat at the sound of his alpha speaking.
"Yes alpha?" Yuuji replies obediently and Gojo groans. Fuck he's so sexy calling Gojo his alpha like that. It's driving him crazy knowing he can't have him yet. It's taking everything in Gojo not to throw Yuuji on his back and fuck him senseless. It would be so easy to do too.
He could pin Yuuji beneath him and ravage him. Claim him properly and fill him with his seed until Yuuji's belly swelled with their child. Gojo would breed Yuuji until there wasn't a drop of cum left in either of them. He imagines Yuuji's stomach rounded full of his babies and growls possessively.
He wants that. He wants that so badly he can taste it. But he can't. Not yet. Not when Yuuji is still so small. So fragile. So young and naive. He wouldn't survive child birth. It's too soon to be thinking these thoughts. It's too soon to act on them. Yuuji needs time. He needs time for him to understand what being an Alpha's omega entails. To understand that being an alpha's mate means giving up your own freedom. That being an omega means sacrificing yourself to the alphas desires. Being mated to an alpha means submitting your entire self to them completely, wholly. Yuuji has to understand what he's agreeing to when he asks for Gojo to claim him. And he will eventually.
Gojo knows that for sure now because he'll be damned if anyone else gets to Yuuji before him. Yuuji is his. Only his. He belongs to Gojo and no one else. No other alpha will ever get to touch him.
" I'll accept your courting gifts." Gojo declares suddenly surprising Yuuji. Yuuji's eyes go wide before lighting up with joy and excitement. "I'll accept them all, Yuuji . You're mine now okay?" He cups his cheek tenderly stroking his soft pink hair back. "Only my omega."
"Only yours, alpha." Yuuji agrees easily and Gojo smirks satisfied at the confirmation. Good. He doesn't want to share his little treasure with anyone.
Yuuji beams up at him happily before launching himself into Gojo's arms and squeezing him tight. Gojo hugs him right back lifting Yuuji clear off the ground. He swings him around in a circle laughing as Yuuji giggles uncontrollably in delight.
"Thank you thank you THANK YOU!" Yuuji squeals excitedly. "I can't wait to tell Grandpa!"
"You better hurry then." Gojo says while placing him down. "You'll be late to school if you linger here any longer."
"Right!" Yuuji nods before turning to run towards the entrance gate. "I'll see you tomorrow alpha." He waves goodbye and Gojo returns the gesture. "And remember," Yuuji shouts over his shoulder. "You're all mine too."
Gojo grins widely watching as Yuuji disappears inside the building heading toward class. He feels elated and lightheaded with happiness. He can't stop smiling like a fool in love and he probably looks ridiculous but he doesn't care about appearances right now. All he wants is Yuuji in his arms. He's never been happier. He doesn't think anything could ruin this perfect moment.
Gojo's mind supplies him with thoughts of their bonding ceremony and the mating bite he'll place upon his mate's flesh. Of his first time mounting Yuuji , making sure to give him the morning after pill. His first time knotting inside of his little omega's tight virgin heat. The feeling of Yuuji 's tight walls clenching around him. He's so small And Gojo is so big. It's gonna be a tight fit but he'll manage somehow. He'll make it work.
He can imagine his thick cock stretching his little omega's hole open, splitting it open on the sheer width of it. He imagines Yuuji crying out underneath him, tears leaking from his red puffy eyes. Yuuji would sob brokenly and cling desperately to Gojo's broad shoulders.
His sweet little omega, taking every last inch without complaint. Taking his knot without hesitation because he knows he must. Because he knows that's what alphas expect from their omegas and it's Yuuji's role to serve him however he wishes. Yuuji would be so good for Gojo. So obediently pliant and submissive to his alpha. He'd beg so beautifully too, pleading to have Gojo fill him up, begging to be bred, begging for release as Gojo fucks into him relentlessly.
And Gojo would gladly grant all his pleas and desires in due course.
But first Yuuji has to learn how to be a proper omega for his alpha. And Gojo will teach him, oh yes. He'll be the best omega he can be. For him. Only ever him.
Itadori Yuuji is going to be his and his alone forever.
