A touch of heat
It was to be expected that Satoru would go into heat at some point. He had been on heat blockers for far too long and when his first intended mate died he saw no need to stop. However, after meeting Sukuna Itadori things changed. Satoru found that he could love again once Sukuna had broken the walls that Satoru built around his heart. The doctors had suggested that since Satoru had been on blockers without stopping the chance of a heat could be very slim, but with the right amount of alpha scent and letting instinct throw the chance of a heat could happen would be greater.
They just didn't expect it to happen so soon.
It had been about a year since Satoru stopped taking his heat pills. A year to let his natural scent finally come back to normal instead of smelling chemicals. Satoru worked at a kindergarten school where he met Sukuna. His nephew, Yuji, was his student and would clinging to Satoru when he first started going to the school. Sukuna would have to pry Yuji off of him when it came to pick up, which is how they started talking.
That morning Satoru felt off. Sukuna had already went off the work at the company he owned, which left Satoru to his own as he felt too hot to move. Maybe that should have been the first indication of something off.
Either way Satoru washed and got dressed, his stomach hurt so he didn't eat much and proceeded to get Yuji ready.
Even Yuji had acted a bit differently too.
Curling up to Satoru at any given chance and would cling even tighter.
Though none of this was ringing warning bells.
They make it to school and everything feels fine for a moment. He didn't feel sick and during the middle of story time he felt better. When lunch rolled around that when things went downhill fast.
He started feeling sick all over, even feeling faint too. "Yuji get..get Mr. Nanami" He then leans on his desk as Yuji goes to the next to get Nanami. Nanaim comes into the classroom and has to take a step back for a minute before entering. "Gojo...why did you come in like this?" Nanami is helping to the chair and sits him down. "Like ...what?"
Nanami looks at Gojo like he grew two heads. Then he remembered. "Gojo... you in heat. You didn't realize it?" It takes a moment for Nanami words to hit him, but when they do gojos eyes widen. "I-im in heat!?" He whispers yells to which Nanami nods. "I've sent Yuji to get Shoko. Sukuna should be notified soon." Gojo nods but is lost in thought over his heat starting.
"Nanami could Yuji stay with you?" Yuji had been in Sukuna's care since his twin brother died. Essentially Yuji and Sukuna don't have anyone else since Waske was in the hospital to look after Yuji. "Sure." Gojo smiles but soon lets out a groan of pain when he feels a wave of cramps rushes over him. "W-we'll send Uraume with a bag of clothes." Shoko then rushes in.
"Yeah your in heat alright... Think you can walk?" Gojo gives a nod. "Gojo?" Yuji's voice interrupts them. "Awe my little pup. It's okay." Gojo tries to calm Yuji down a bit. "I'm just not feeling good, Shoko gonna help me feel better okay?" Yuji looked saddened by this and nodded. "Stay here with Nanami k?" He gives another nod and clings to Nanami pants leg looking as Shoko helps Gojo up and out of the class.
"Sukuna is on the way, so just lay down in here okay?"
Satoru nods and curls into the blanket that Shoko give him. "I'll be just outside the door if you need anything." He gives a hum and she closes the door.
The wait felt long and new developments happened during that time. The cramps had gotten stronger and more frequent, slick had started leaking out slowly too, and the need for his alpha was great. He was so lost in his heat he didn't even notice the door open the room he was in, till he picks up a familiar scent. Ash and pine with a touch of amber.
"A-alpha?" Gojo calls out and is greeted warmly with his alpha hand touching his forehead. "Satoru..." When Sukuna got the call from Shoko he was shocked. Sure they both didn't know when Satoru heat would hit but it was still a shock. He told his assistant Uraume that he would off for a week and to not bother unless it's was a real emergency and takes off to the school. He gets there and sees Nanami waiting for him outside. "How is he?"
"Not too bad, he told us in just enough time before things got even worse." He opens the door to let Sukuna in. "Satoru asked to take care of Yuji till this is over if that's okay." Sukuna nods in agreement. "It would be for the best. I'll have Uraume drop off some stuff at your place later. Thank you for doing this."
"It's no trouble." And Nanami shows him to Shoko who fill him on how Satoru is doing. "Is it okay to move him?"
"Yes...things might be different since this is his first time, but moving to a place he is familiar with would be better for him." And so Sukuna enters the room. Satoru scent was much stronger than it had been and had almost thrown him off when he walked in.
"Let's get you home yeah? Back to your nest." Sukuna speaks softly. Satoru gives a nod still slightly out of it and lets Sukuna pick him up and carry him out.
Even though the air was on in the car ride home it still felt too hot to Satoru. Heck, even the car ride felt too long. "Alpha!"
"Almost home." Sukuna trys to comfort his love. They were just a block away now and soon they will be home.
Sukuna is quick to get Satoru inside their home. If it were for his self control they wouldn't make it to the room. Once Satoru gets in the nest he purrs and take off the clothes that feel itchy on his skin while Sukuna steps out to get water bottles and the bag they are mad for this incase it happens. The bag had snacks they held them over the first round of heat till Sukuna could get some real food. In reality they didn't know how long Satoru heat would last. A typical omega heat would last a week for four days depending, but this was Satoru. He's never had a heat so who knows how long it would be.
He goes back to the room to see a sight that felt to heavenly even for him. There on the bed, Satoru is whining legs spread out giving Sukuna a beautiful view of his dripping wet pussy that he just so happens to be playing with. "Al-Alpha" Sukuna's fangs had fully dropped and he was losing his control fast.
"Satoru." His voice was deep and partially growling. Satoru sent is overwhelming but he can't get enough. "Omega. " he gets on the bed
Satoru moves his head to the side, neck fully exposed, he submits. Sukuna gives, that's was the last straw. He's all over Satoru kissing his lips to his neck and everywhere between. Not yet marking the neck.
Satoru whimpers
While the touches and kiss felt good it wasn't enough. He needs more. Seeming to get the hint one hand of Sukunas drifts down and slips between the folds. Satoru eyes widen and arch a bit even though nothing happened yet. "So sensitive, I haven't put my finger in yet."
Sukuna teases spreading and smearing the slick on his fingers and Satoru's folds. Satoru hips move of their own accord, putting on Sukunas fingers that aren't even in him yet. "Alpha!"
Giving Satoru one last kiss Sukuna pulls away and focuses on Satoru slick. His finger presses in a bit slow, working Satoru a bit more open every time he pulls his finger out to push back in again.
"In! In Alpha!" Satoru sqearms
Sukuna would take his time another day, he would have to tease Satoru during his next heat. He wastes no time in taking his fingers out and replacing them with his cock. Satoru is so open he takes Sukuna's cock to the base. Sukuna bites his lip, making it bleed, while Satoru arches and silently cries. His walls going tight around Sukuna's length trying to keep his alpha in.
Satoru moans, something in feels slightly satisfied now that Sukuna is in him. He let out a chirp of happiness, something he had never done before. Everything felt different with a heat Satoru realized. He's more sensitive than usual, he wants to wrap himself up in Sukuna sent, to mark and bite to stop the ache in his teeth. Was this how Sukuna felt when he was in a rut? He wondered to himself
Though they had sex before, it was different. Satoru never understood why Sukuna got worked up about things like keeping him close and marking.
Satoru claws at Sukuna back
Sukuna moans at the pain which drives him crazy. Satoru cries big fat tears once he feels the star of Sukuna knot hit with every thrust, growing more every time pushed back into him and spreads him further.
"k-Kuna! Sssu-na!" the press of Sukunas knot pushing in had Satorus Omega purring.
"So good. My omega. Taking me so good. Good mate." Sukuna chanted into Satorus ear. He knew Satoru was getting close. How he pulsated around him, clenching at each thrust now that his knot was fully inside him. Something primal rose to Sukunas mind as he continued. He brought Satorus legs from his waist to his shoulders and began to more sloppy and hard. Satoru eyes widen at the change, his eyes roll, and his mouth opens letting out whines and moans. His knees were so close to his head and Sukuna scent right in his face.
A matting press
They are both lost in their own pleasures and feral
As Satoru arches his back, his toes curl, and moans. Sukunas tip presses right up against him. Hes so close.
"A-alpha! Alpha!" Satoru chants. He clenches hard around Sukuna. Both are nearing their climax. Sukuna growling, the way his mate clenches and throbs around him has him close to cumming. And to think this is only the start of Satoru heat. The need to cum is strong, Sukuna teeth pulsate with the need to mark and claim. He finds himself close to Satoru neck breathing in his secent when he bites. Satoru arches his back as he cums around Sukuna, his hands scratches Sukunas back as he lets out a loud moan. Sukuna thrust get fast and sloppy when Satoru cums, chasing his own climax.
He cums in a deep moan, Satoru let's out a weak whimper feeling Sukunas fill him up with his knot. Sukuna holds Satoru close, pulling him to lay on top of him as fills his omega up with his seed.
They pant hard as they come back to themselves. "S-suku...nghh" Satoru is in a haze. Tired from their activities and content with the fullness. Sukuna, rubs Satoru lower back and gives quick pecks to calm him till his knot gone down enough.
"mmmhmm....s-...sukuna..." Satoru voice is rough and dry as he speaks. "Im here...im right here little omega. " purrs continuing his menstruations. Eventually Sukunas knot does goes down and he gently eases out of Satoru, who is sleeping till his next wave of heat. Getting up he gets a backpackready full of Yuji things and sends a quick message to Uraume to come pick it up and drop it off at Kentos place. He also gathers some more water bottles and other things for Satorusince he knows he will be hungryby the time he wakes. After grabbing a few other things hes back in the room and in the nest like he never left.
He keeps a close eye on Satoru. Watching and feeling his alpha senses kick in.
Finally they are one
