You are a 3rd year student at Tokyo Jujutsu High, you were one of the few omegas that made it into the school, Kugisaki and Fushiguro being the only other two.
You had locked yourself up in your room as soon as your monthly heat was about to start and made sure to tell your teacher Gojo about it first so he knew to keep you out of any missions and classes for that week.
Gojo, being the oversharing loudmouth he is, spills it to Nanami, and with Nanami having a liking towards you after a couple times mentoring you, takes this opportunity to take a care kit to your dorm room as a gift
-
You were curled up naked aside from your boxers in your messy nest, it was just a small nest as you didn't own a lot of blankets or clothes so you had asked Inumaki and Maki if they had any extra blankets or clothes they wouldn't need for a week, with a promise of washing them after.
You muffled a whimper with a body pillow you hugged as a wave of heat rushed through your body, causing slick to drip from your entrance, your cock pressing firm against the pillow as your hips jerked against it, trying to get any sort of relieving friction.
Nanami chose to go to your room after lights out in the dorms, holding a basket of some sweet snacks, a few granola bars, and a couple bottles of water, it was all wrapped in a blanket with another folded nicely ontop.
You heard a soft knock on the door, you whimper quietly into the pillow before speaking up softly "wh-who is it...?" you sat up, wrapping a blanket around yourself as you slowly walked over to the door.
"Its just me (Y/N), Nanami, I have a basket of some items you might like, I heard you started your heat and wanted to bring some comforting items to help you through it." Nanami heard you shuffling around, before he heard you stop in front of your door.
"Nanami-san..? You didn't h-have to do that... Thank you s-so much..." you paused for a moment, making sure you were fully covered by the blanket you had grabbed, you opened the door a little bit and peeked around the side, glossy eyes staring up at Nanami nervously.
Nanami always liked that about you, always being so submissive and perfect whenever you were around him, and a feral beast when fighting, Nanami felt his inner alpha pacing as it let out a rumbling purr in his mind, repeating 'mate. my omega. mine. mark. knot.' "It's not a problem, I wanted to make sure you were eating food and had enough to drink"
You opened the door a little more and accepted the basket with a low bow, your neck looked so soft and markless, his Alpha growled at himself to mark you and to take you for himself.
You felt a shiver run through your body when your hand rubbed agaisnt Nanami's when you grabbed the basket handle. "t-thank you again, n-nanami-san..." you spoke quieter, standing up again to close the door, only to whimper and curl in on your stomach as a wave of heat rushed over your body again, slick dripping down your legs, your cock throbbing painfully in your boxers.
Nanami shivered and muffled a growl, "(Y/n), are you alright?" your scent overtook his nose, your scent was a wonderfully sweet clove and orange scent, with an undertone of pine.
You looked back at Nanami, seeing a look of restraint in his eyes as he stared down at you, you were trembling, and you so desperately wanted to be taken care of by Nanami.
Your omega has been doing flips since he said it was him, it was purring and begging you to submit to him, to give yourself to him, to become his mate. Your omega whimpered when you pulled back, your hands trembling.
"Im okay... I'm s-sorry you had to see th-that...." you spoke with a shaky voice, tears pricking the corner of your eyes. Nanami sighed gently, ruffling your hair softly "Take care of yourself" and with that he waved and said goodbye, you doing the same and closing the door.
After you put the basket down you grabbed the blanket that was on top and instantly sniffed it, a keen leaving your lips as you took in Nanami's pure alpha musk, his scent smelt like vanilla and a smokey cedar, no undertones from what you could tell, he must have used the blanket before he gave it to you.
You quickly opened the door to your room, catching up to Nanami quickly and grabbed his suit sleeve "w-wait..... N-Nanami-san... um....!" you bit your lip, your whole body treming under the blanket you were wrapped in.
Nanami stared at you, your back lowered in a submissive pose, head tilted down as you played with a part of the blanket. "Do you need something else (Y/n)?" he spoke in a low gruff tone, it sent shivers through your body as your skin prickled with heat, a keen slipping past your lips as you collapsed into Nanami's arms, the blanket falling off your shoulders.
He held you up, ears burning hot as he stared at your vulnerable naked form, trembling in his hold. "N-Nanami-sann.... pleasee.." You whimper, gripping onto Nanami's shirt, looking up at him with glossy lidded eyes, mouth parted as you panted, legs pressing together as slick dripped down your legs.
Nanami gave a low growl, his arms finding their place under your shoulders to lift you up, grabbing the blanket as well, wrapping jt around you. You wrapped your legs around his waist as he hugged you close, his nose pressing against your scent glands, causing a whiney keen to leave your lips again. Nanami shushed you, carrying you back into your room, closing the door, locking it and laying you in your nest.
He pulled his neck tie off, letting it fall to the floor as he asked "Are you sure about this (Y/n)?" to which you only nodded, he grumbled softly "answer properly omega." he grumbled gently but sternly, you whimpered "y-yes Nanami-san, alpha, please, It h-hurts so much, help me pl-please"
You reached up towards him, and he growled again, sliding his suit off, then the blue dress shirt he had on underneath, crawling over top of you in the nest after taking his shoes off, letting his hands roam your hot sweaty body.
You whimpered as he ground his hips against you, your back arching as a moan slipped past your lips. Nanami groaned, pressing his lips against yours, muffling your moans as he ground his hips against yours again and again.
Nanami pulled back and sat up to admire you, hair a ruffled mess, kiss plumped lips parted as you panted heavily, eyes glossed over and lidded, body splayed out under him, perfectly submissive.
"Fuck..." he whispers, a low growl rumbling in his chest, he slicked his hair back and took his sunglasses off, setting them on your nightstand. You let your own hands roam Nanami's body, running them over his broad chest, his wide shoulders and down his strong arms, all the while he's trembling, fighting with his inner alpha for control.
You let out a surprised yelp when Nanami lifted your legs up, pulling your boxers off and tossing them onto the ground with his clothes. Your blush covered your cheeks, ears and your chest and neck, feeling so vulnerable and out in the open.
Nanami growled as he leaned down, giving a long lick to your soft virgin omega pussy, before dragging his tongue up your shaft, causing a loud moan to leave your lips. You covered your mouth and whimpered, legs trembling as they drapped over Nanami's shoulders, he continued licking at your entrance, as more slick poured out.
He pushed his tongue in, a low growl rumbling deep in his chest, you tasted so good to him, so perfect and delicate. Your legs trembled as you whined "N-Nanami-san... please.." he looked up at you, his eyes dark and predatory, you let out a keen "p-please.... alphaaa..~" you reached out to him, and he growled again, slotting his hips between your legs as he moved closer to you.
You panted, feeling overwhelmed by his scent as it surrounded you. You wrapped your arms around his shoulders and pulled him down into a kiss, both of you purring loudly into the kiss. Nanami ground his clothed hard on against you, your slick soaking his pants.
He groaned as he nosed at your glands, taking in your scent with each breath. You dug your nails into his back, sobbing out, you yourself taking in his scent, nose pressed firmly against his glands.
Nanami grumbles softly and slides his hand down, rubbing a long finger along your pussy, collecting some slick on his finger before slowly pushing it in, a keen leaving your lips as you arched your back "A-Alpha!!~" you gasped when he pulled his finger out and turned you around on your hands and knees.
You panted as you looked back at him, eyes half lidded as you got into position, front down and your butt up in the air, on full display for your alpha.
your alpha.
Nanami felt like he could have passed out, seeing you being such a good omega and getting into position, he felt his pants pockets hoping he brought a condom, biting his lips when he didn't feel any. You looked to your nightstand and reached over, pulling open the drawer, reaching in for a condom a friend gave to you once as a joke.
Nanami couldn't help but chuckle softly, thinking you were the one that bought it "what a naughty puppy~" he took it from you when you offered it to him with an embarrassed look on your face "I wasn't the o-one that bought it..."
Nanami chuckled again, opening the packet and slipping the condom on himself, groaning softly, it was a little small. He thought for a moment maybe they shouldn't, and even voicing his concerns to you. "(Y/n), I don't think it would be a good idea for me to go any further." he paused "but I can still hel-" you cut him off by whimpering loudly, looking back at him with teary eyes "A-Alpha please.... I want yo-your knot... please... It hurts to much, m-make the ach-aching go away...!"
Nanami swore he felt his heart stop for a moment after hearing that. He growled deeply "Tell me if I get too rough with you." He sat back on his calves and slid his fingers through the slick dripping from your cunt, slowly pushing two fingers in, causing you to gasp at the intrusion, before a whiney moan followed after as Nanami pushed his fingers all the way in.
He proceeded to finger you, stretching you slowly, adding a third after a minute. You were panting and whimpering, clenching around Nanami's fingers as the knot in your stomach started to tighten impossibly tight "A-alphaaa~ im close..!" you whimpered as you looked back at Nanami, a begging look in your eyes.
He growled deeply "good omega~ asking for permission~" he thrusted his fingers harder "such a good boy~" he purred deeply, reaching his free hand down to grip your cock, he started pumping it quickly "you can cum~ my good little omega~" Your eyes rolled back as pure euphoria washed over your body as you came, ropes of cum landing into Nanami's hand.
He rode you through the entire thing, slowing down his movements before pulling his hand away from your cock and his fingers out of your pussy. He licked both clean, growling at the taste "Fuck you taste so good, do you think you can go one more time?"
You panted heavily, body trembling as you stayed in position "y-yes alpha..~ I want more, p-please, I want you too kn-knot me.~" Nanami Growled deeply, leaning over you, one arm reaching under you to hold your torso, while the other reached up to cover your mouth in a tight grip "Good omega~" he growled into your ear, slamming his hips into you, his cock bottoming out, balls slapping against yours, his tip pressing right against your womb.
Your eyes rolled back, tears falling down your cheeks as a cry of pleasure was muffled by Nanami's hand, another orgasim surged through your body, he growled, your tight pussy squeezing his cock so perfectly, you felt so full and so overwhelmed, his cock stretching you out.
He started slowly, rocking his hips back and forth at a gentle pace, grinding his hips flush against yours, pushing as deep as he could. he could feel where his dick was pressing, a bump on your stomach showing.
Nanami growled, thrusting a little harder, he nibbled at your neck, no collar to protect you from his inner alpha from biting and claiming you for himself. Nanami held back though, moving to bite at his arm whenever he had the urge to bite you.
You were a mess under him, tears running down your cheeks and onto his hand covering your mouth, drool dripping down your chin, muffled whines could be heard from behind his hand.
You were gripping the blankets in your nest in tight fists, back arching away from his chest. Nanami panted heavily, hips slamming against yours as his knot started growing inside of the condom.
"Fuck, I'm going to knot you so good. Fuck I want to breed a litter into you so fucking bad." He ground his hips hard against your ass, popping his growing knot in and out of your pussy, before it got to big to do that anymore.
You were sobbing and moaning the whole time behind his hand, eyes rolled back as you let the pleasure carry you. He pulled his hips back, pulling both of his hands back to spread your plump slick covered lips, growling as he just slightly pressed his cock in and out.
"I want you to really cover your mouth sweetheart~ cause this knot is big~" You followed his command and stuffed your face into a pillow, hugging it close to your chest.
Nanami pushed in hard, groaning as he struggled to push his knot in, before grunting and moaning deeply as it popped in, locking you together. You arched your back, crying out into the pillow, orgasming around his cock once more, slick dripping out past his knot, your walls convulsing and tightening around his cock, driving him to his climax as well, filling the condom with heavy hot ropes of cum.
But neither of you knew, the condom had torn, ripping from the size of his knot, his hips jerked a couple times, pumping a large amount of cum into you, filling you up.
As you both started coming down from your highs nanami laid the both if you down on your sides, him spooning you with his cock still tightly knotted inside you, he has his arms wrapped around you, slowly grinding his hips into you, low purrs and quiet moans coming from both of you from time to time.
With your omega now fully satisfied with getting a knot, your heat will be mostly gone by morning. You ended up falling asleep at some point, not remembering Nanami pulling out.
In the morning, you woke up to the sun shining through a crack in the curtains and into your eyes. You let out a groan and turned onto your other side, facing away from the window and right into Nanami's chest.
You gasped softly and looked up to see him looking down at you, a painfully worried look stuck to his face, he looked like he couldn't think of what to say, his mouth opening and closing a couple times before he was finally able to figure out what to say.
"(Y/n)... What happened last night shouldn't have happened... And I think you know that..." You jolted, looking down, you bit your lip as you nodded softly, tears pricking the corner of your eyes.
Nanami paused for a moment before continuing "Awhile after you fell asleep my knot deflated.. and when I pulled out, I found that the condom had broken..."
You froze, your eyes going wide as you moved your hands to your stomach before looking up at Nanami, mouth open in shock. "T-The condom... broke...?" Nanami nodded and sat up "I have no right to tell you what to do with your life... so whatever your decision may be, I will help you through it... If you let me."
You sat up and sat beside Nanami, looking at your lap, fidgeting with your fingers "Then... does that mean you will help me with the baby if I keep it...?"
Nanami placed his hand on yours, squeezing gently "If that is truly what you want." You looked up at him, eyes shimmering with tears as you nodded "yeah... I wanna keep it..." When you saw a slight smile form on Nanami's lips you grab his shoulder softly and pull him down for a kiss, your soft lips fitting perfectly with Nanami's.
He purred deeply and pulled you into his lap, you straddling his thighs as he wrapped his arms around your torso and yours around his neck. You melted into the kiss, loud purrs coming from you as you both kissed.
Once you pulled away you were a little heated, a post-heat wave of heat washing over your body, you panted gently, looking up at Nanami.
Nanami chuckled softly, placing his hands on your thighs, rubbing small circles on them with his thumbs. You whimpered, leaning on him, head resting on his shoulder, his scent flooding your senses.
A keen left you as another wave of heat washed over your body, slick dripping from your entrance. Nanami growled as your own scent surrounded him, he squeezed your hips softly before grinding up against you, his now hard cock pressing against yours between you both.
You moaned softly, hips jerking against his, more slick dripping from your soft pussy. Nanami growled, lifting your hips, positioning you over his cock, he leaned down and licked at your neck "Will you let me mark you...?" he rubbed his tip against your entrance.
You whimpered, nodding "y-yes, please mark me alpha~" he kissed you as he pushed himself in fully, you were already nice and tight again, a slight burn spreading through your core as his cock stretched you open once more.
The kiss muffled your loud moan, squeezing around him even more, your legs trembling around his waist as you clung onto his shoulders.
He pulled away from the kiss panting, his chest rising and falling out of sync with yours as you whimpered, your body slightly limp as you let Nanami move you; He lifted your hips slowly, and when he brought you down he thrust his hips up, pressing even deeper in you, his cock pressing harshly against your womb with each deep thrust.
You muffled a cry of pleasure by biting Nanami's shoulder gently, your belly being pressed out by how big Nanami was. He growled when you bit him, his knot growing slightly "f-fuck... (Y/n)... I'm going to knot you again... mnf, so good... You'll be so full of my cum. mnnf~ I'll breed you real good again..~"
He groaned as he talked, his alpha fangs poking out as he started licking at your scent glands, huffing as he continued thrusting, you muffling your moans in one of your hands now, eyes rolling back.
You cried out into your hand when he bit you, his knot popping into place, nestled deep inside you, hot ropes of cum painting your insides once more.
You came with a whiney moan, your walls convulsing around his cock, your cum landing on your stomach, some on his.
He held you close, rubbing his hands on your back gently, a deep rumbling purr coming from him, his alpha happy and content. You yourself started drifting off, laying against Nanami's chest. He moved the both of you so he was leaning against the headboard, you still sitting in his lap, his cock making you feel so full and content.
"I love you Kento..." you mumbled softly as you dozed off, he purred deeply, loving hearing his name on your lips "I love you too my dear (Y/n)."
