I've got you

Synopsis: Whilst completing a mission with your oldest friend, you were a little out of sorts than your usual self. It was only after you placed the veil around the abandoned building did it fully hit you as to why. Braced up against the cool side of the wall, all you could do was cry out for help only to find it in the man you loved completely.

Notes: This is a part of an ongoing series of trades with my dear friend @loganwritesprobably. This is the omegaverse x reader trade! First time writing for Ijichi!
The drive to the site was in relative silence. The soft music played on the car speakers, the nozzle adjusted every now and again to compensate for the beat at each interval by your driver and colleague working with you on the case. Ijichi had shared soft small-talk before you both bit the bullet and began to sing softly to an old Panic! song from back when you were both in highschool together.
As the song drew to a close, you placed your hand over your chest and gulped hard to recover your voice after blaring out the lyrics together. You twitched and coughed while moving your neck about, feeling a rise in temperature in your heart that you elected to ignore.
“Are you okay?” Ijichi asked you, followed by your name at the close. Ijichi reached over to the passenger side of the car and drew down the small drawer with water bottles in the dash, “Take a few sips. You sang your heart out just now, and I’d hate for you to go down in the next fight due to dehydration.” “Thanks, ‘Jichi,” you nodded to him, brushing your hands with his and apologizing with a polite nod to your head, “I don’t know what’s gotten into me today. First, I almost went and met you in my pajamas, next I got down the end of the hallway before I realised I was only in socks, had to change them before I left, by the way.” You unscrewed the top cap of the bottle and took a few gentle sips, “I’m a hot mess.”
“If it's any consolation, you smell nice today,” Ijichi shrugged with a small smile, “New shampoo, or fabric softener or something?” You knit your brows together in thought while you mulled those words over. You took a moment to go through your checklist before you shrugged at him.
“I honestly can’t remember. I don’t think I did? Maybe moisturizer? Sunscreen?” you shrugged and raised your hands to your face and slowly brushed the hand holding the cap against your cheek, “Also, you can smell that?” Ijichi coughed a little to cover his laugh, shaking his head and offered you a napkin placed in the middle console of the car.
“You dropped water on your face just now,” he shook his head and handed it to you without a glance, “You need to be more careful. After the mission, I’ll take you out for coffee. Maybe an energy drink. Or, I should just take you home and cover your shifts until you feel more like yourself again.” “Thanks, Ijichi,” you sheepishly took the napkin. Screwing the cap back on the bottle, you moved down the passenger visor and began to blot your face while peering at your reflection. You noticed your pupils were slightly dilated, but you mulled that down to the earlier stress of your disheveled morning.
Ijichi slowly drove the car into the lot beside the large building. The presence of the cursed spirit caused you both to wince at the feeling. Nothing you both couldn’t handle, but enough to cause you a moment to grit your teeth. Ijichi was the first to exit from the car, walking to your side and opening the door for you as you placed the napkin and bottle against one another in his cup holder.
“Keep in contact with me, okay?” Ijichi nodded towards you as you exited the car door, shutting it behind you and locking it, “You got the veil?” You nodded as you elevated your hands to activate it. You gave Ijichi a smile before he slowly stalked the area for a cause of the presence of the cursed spirit.
When glancing at the domed wall over the building site, you felt that uncomfortable edge return to you once again. It was warm, flushed and simply not welcome in your body. You moved down the opposite alley away from where Ijichi had ventured to and drew your hand up to place it upon the cool stone. It was then that the full flush rose deep within you, causing you to let out a soft, little mewl and cry out in anguish.
Bracing your hand against the wall of the alleyway, your blood thrummed and ricocheted within your eardrums. With each raging pulse flooding through your veins, you felt your need clench and knit itself into a raw, clotted agony you had not experienced in years. You had almost forgotten the last time you had taken your suppressants. Work had been excruciating with the new recruits at Jujutsu High. There was no failsafe, there was no plan for when it came to this, especially not while in a public place.
Heat.
White-hot heat scorched through your body like a cattle brand to hide.
Sizzling, excruciating, and causing you to react by simply thudding your body against the wall where any alpha could find you. Without much hesitation, and simply to balm the need, your dominant hand immediately flew down the front of your pants where slick had coated your thighs and cunt with its presence. Quickly, you placed your index and middle finger at the entrance of your slit and curled them into your core at a rapid pace. You’d hoped, prayed, that this time would be different than all the rest in being able to find relief with yourself enough to call the beta protection agency to escort you home.
There was no relief to find you. No matter how much you attempted your usual tricks to get you across the finish line. Nothing you could do could satisfy that deep-seeded craving to be bred and knotted by an alpha. You didn’t care who at this stage. Your mind was clouded by the need that you had tried so hard to avoid for years.
The phone in the front pocket of your pants began to vibrate and pulse away with your ringtone falling on deaf ears. The need had you hopelessly rutting into your hand and your pocket to satiate the crude need to reach your peak before you answered. Yet, nothing you could do managed to fall yourself into that sweet abyss.
Nothing took you away from this moment as you continued, tucked in a corner in between a dumpster and a pile of boxes behind the vacant lot you were originally called to investigate with your partner on the case. The cursed spirit in the area had to be quickly and quietly exorcised by you or Ijichi before it got too far out of hand for any other to handle, yet you were rendered incapacitated the longer your body thundered with the loud scream of visceral need.
No matter how hard you attempted to reach for the phone in your pocket, your body screamed at you to knot yourself on your fingers. Your entire soul cried out for an alpha in that moment, although you couldn’t truly hear if the voice you screamed with belonged to you or not. Your motions continued while your body moved to peel away from your clothes, finally leaving you bare from the waist down and on all fours while rutting against your hand.
“Pick up the phone. Pick up your phone, please. I told you to stay in contact-...” Ijichi’s voice halted and broke down mid speech as he stepped towards the scent he was following. Although his hand redialled your number to inform you the spirit was taken care of, his nose was able to follow where you were without that ringtone he loved so much.
On shaky legs, Ijichi’s entire body was thrown into the need to protect, to claim, and to cover your scent with his own. That citrussy tint with honey and sugared bread caused his eyes to roll as his knot swelled in his pants. His teeth chattered while he controlled every movement, feeling almost as if his feet were escaping shards of glass while returning home to your comfort.
“Omega,” he shuddered at his own tone as he called for you, truly unaware that his soul was commanding you while his spirit wanted nothing but to hold you close. He coughed as he shook away his own need, finally finding you while you sobbed and weeped for him. Your hips rolled into your hand while your body continued to burn with raw, unbridled need.
“Help me,” your voice was softer, smaller, and filled with far too much desire than you could control, “Ijichi, I need… I need… I need-.” “-You need to get up, omega,” he whispered as calmly as he could, “Let me help you to the car. I’ll put you in the back seat, just let me help you.” Ijichi moved his hands towards you and hovered over your burning skin. A whole shudder vibrated through his body as he curled inwards of himself. Although primarily reading as a beta, due to the raw energy his coworkers musked themselves in and the fact he cares very much about the comfort of his colleagues, Ijichi’s scent finally breached through the confines of his clothes and moved to cover you in it against his inner will.
Ijichi drew you into his arms and immediately morphed your body against his torso to shield you from any in the area that would cause you harm. In the contract you were both assigned, this area was abandoned due to the nature and shunning of the building harboring the cursed spirit. You were completely alone, yet Ijichi felt the need to carry you towards the safety of the car to remove your scent from the area.
The dark-haired man fumbled through his pockets with one hand while the other exceeded your natural assumption of his strength while he held you. He quickly opened the car and carefully placed you on the back seat before peeling himself away from you. The moan that escaped from both of you surprised one another as you backed yourself up to him to remain in contact.
“I know, I know, I know,” Ijichi rushed those words over your skin, whispering his soothing voice before shutting the door with you both inside the back seat of the car. He tried to move down towards your dripping cunt where your hand was buried inside yourself, eyes glazing and simultaneously rolling in his head at the sight of your slick gliding in and out of yourself.
“I need you, Alpha,” you whimpered as you attempted to present yourself as best as you could while in the cramped space of the backseat. You removed your hands and spread your walls for him, watching as your ring of muscle contracted around nothing. Ijichi’s entire form attempted to engulf you immediately in the seat, his body sweating while he tried his best to focus his motions on clumsily giving you relief while peeling himself away from his layers.
His hands swatted at yours to remove them from your body, wanting to see your response for himself without your digits interfering. As soon as your hands left your body and were replaced by his, you shrieked in glee and backed yourself onto his hand. “Wait, just-! Just hold on-!” Ijichi barked at you while he maneuvered himself behind you, “There’s not enough space for me to take care of you right now. Just give me a second.” You found yourself swiftly moved and placed comfortably in the centre console between the front seats. Your chest brushed up against your water bottle from earlier and the napkin used to clean yourself with.
As you tried to wriggle back to make contact with Ijichi again, you found yourself quickly wrapped between two seatbelts to hold you in place. His jacket was messily screwed and placed beneath your head atop the bottle, while he clicked the drivers seatbelt into the passenger fastening, and passengers into the drivers fastening. You were completely rendered and held comfortably in place while Ijichi wrangled himself behind you, pants shimmying down his thighs with a jingle of his belt buckle.
“I had to secure you so you stopped wriggling, sweetheart,” he cooed sweetly at you, his hands moving to your ass and slowly caressing your flushed, damp skin, “I’m going to take care of you, okay. You need to just be comfortable there for a moment so we can take the edge off what’s going on, okay?”
“‘Kay, ‘Jichi,” you whimpered and sobbed while your hands moved to butterfly in front of your torso, “I tr-trust you, Alpha.” The groan exiting his throat caused your cunt to clench around nothing before you felt his hands card through your folds.
“I knew you smelled good today,” he chuckled dryly as he found your clit and pinched it gently, “You were in pre-heat. How long since you’ve had your full term?” He used his other hand to gently fist at his cock, grinding his teeth and trying his best not to lose control the moment his tip brushed with your slit, “I need to stop asking questions, don’t I? You just need me to take control. I’ll keep you stuffed so full, sweetheart. I’ve got you. Don’t you worry.”
There was no recognition in your ears of belonging to the sound you made when he stretched you out on his tip, yet from the way your lips circled in bliss, you knew it belonged to you. He let out a gentle groan while he placed his hands either side of your hips and slowly dragged you back down to sit flush on his cock. At the base of his cock, his shaft swelled with a feral need to breed you, to keep his cock settled inside you until his seed took - but Ijichi cast all thoughts aside as he slowly withdrew you away from him before dragging you back down again.
“I’ve got you, my omega,” he whispered his assurances, “You just let me take care of you. Need to keep you comfortable and warm around me. J-Just like that.” His motions picked up as the curve in his cock hit your cervix, feeling the walls shudder and squeeze around his length with every thrust forward.
You were vaguely aware he was speaking whispers to you, encouraging you through your heat and soothing you with the weight of his words in every curved moan. The only thing that kissed your ears was the words ‘mine’ or ‘my’. You knew in that moment that this alpha, that Ijichi, was truly yours. From the way he knew your body, rolling and pinching your clit beneath his skilled fingers while guiding you on a makeshift swing to allow the weight to remove itself from your fragile bones while he fucked you - you just wanted to be completely covered in the scent of your mate while he filled you with all of himself.
The first orgasm ripped through you like lightning striking a metal rod. You could barely process it before it rolled into the next one. Your slick dripped and coated your legs, spasming and shaking with every heavy smack of Ijichi’s pelvis meeting yours. He released your clit and focussed on keeping you saddled and comfortable on his cock, pressing you down onto his knot as it beat your slit like a drum.
Ijichi was groaning, letting the wild nature of his repressed spirit take over in place of the reserved man who was once bullied by Satoru Gojo in highschool. Every gruelling plap of his hips driving into you had his balls slapping missily against your clit and tearing another orgasm from you like he was getting paid overtime for it.
“Oh, you came again. Good little omega. You keep feeling good on my cock, sweetheart,” he grunted out with every rushed breath. You forced your ass back into him, your body screaming at him to stretch you on his knot and claim you for all that you are. Ijichi huffed and panted, groaning while holding you steady, “I don’t want to give you my knot, darling. Don’t push back on me like that. I can’t breed you in the back of a car.”
“I need you-!” you yelped at him, “I need you to knot me, alpha. Why won’t you give me what I need?” Your voice cracked and sobbed, tugging at Ijichi’s heart while he continued fucking you until your slick soaked into the carpet on the rear floor. He choked on his moans and tried to keep your cunt off his knot as much as he could. His glasses had fogged with every breath out and remained that way until he shook his head to cast them aside. Now with his eyes bare, all he could focus on was the sloppy sounds of your cunt sucking him in and joining with him.
“You deserve better than this,” he spoke your name with every particle of his body confessing its adoration for you in a single moment, “I’ll knot you. I’ll knot you, my omega. I’ll keep you safe, I’ll give you my pups, and I’ll keep you safe. G-Gonna fill you up, hold on.”
With a final thrust forward, his knot locked inside you immediately shot a viscous splashback of his pearlescent release slamming into your walls. He let out a thick yelp while your cunt contracted on him, his body immediately lunging forward and lying on your back. His hips stilled, yet his ass dimpled while he rode through his high inside your body. You could hardly focus as your vision split white and had the heaviest and roughest orgasm of your life snapping in your belly and splashing onto Ijichi’s thighs.
Slowly, your breathing became languid and laboured, catching what little air you could gather in the fogged car filled with the pheromones of breeding alpha and omega. Ijichi’s hands moved to unclip the fastened seatbelts, placing one arm around your waist while the other hand reached for the water bottle and jacket he placed beneath your head. He slowly moved you back to curl into his lap, keeping his cock inside you as the knot continued to pulse and release more of his release inside you.
Ijichi placed his jacket around your sweat-damp body, covering you in his scent while his lips found your temple. His kiss felt like a lifeline of connection after solitude, his kiss just sweet enough to cause you to almost cry.
“We need to get your pants, sweetheart. It’s got your phone in it,” he whispered into your temple, “I’ll wait until you’re asleep to get it, okay? You’ll be safe in the seat here. I’ll buckle you in and get the blanket from the trunk.”
“Please don’t leave me here without you. I don’t care. It’s just a phone. All I want is you, Ijichi,” you whimpered in a sleepy daze, feeling the embrace of slumber slowly creep up into your eyes, “It’s all I’ve ever wanted. Ever since back when we were in the same class together, it’s all I wanted. Even when we worked out our secondaries, I didn’t care. I just wanted you. Please don’t leave me, my alpha.”
Ijichi’s heart broke and swelled as your body slowly began to cool down from the first wave of your heat. His eyes rounded and swept with recognition and emotion he couldn’t place. He knew there was a reason he loved your scent, loved being close, and loved being placed on missions with you. It was because he loved you. You were his omega, and he was the alpha you always needed.
“I’ll drive the car down the alley, okay? It’ll be as easy as opening and shutting a door. Then I’ll be right here beside you again,” he whispered as your body began to grow limp in his arms. Sleep took you, and Ijichi waited until his knot deflated to slowly pull his cock outside of your dripping hole. He watched as his release slowly seeped out of you and his hands moved against their will to use his fingers to place it back within you again. “You’re safe with me, my omega.” He whispered gently, “I love you, and I would never leave you. I’ll always take care of you.”
When you awoke, you were clean and in your nest with Ijichi sleeping on the floor beside it. His torso leaned over the pillows on the edge, his hand out and splayed over your back as you slept on your stomach. You felt your heartbeat skip as you reached for your oldest friend, wanting so desperately to simply hold him. Yet, as soon as you did, your heat returned to you and reacquainted your body with the visceral lust you needed to fill it with.
And as your alpha stirred and gazed at you as if you hung the stars and called them by name, you knew you would be forever safe with Kiyotaka Ijichi.
