When he had felt the first trickle of heat, Gojo cursed his terrible luck. His misfortunes had started when he presented as an omega in the deeply repressed and traditional Gojo clan, and continued up until this point: going into heat in the midst of fighting Ryoumen Sukuna.
He was only realizing now that being in the Prison Realm had severely messed up the tracking of his heat cycle, but it was too late.
“You’re distracted,” Sukuna noted as he easily got out of the way of Gojo’s Red.
“Maybe you’re just not worth all my attention,” Gojo replied. He was sweating, and it wasn’t entirely because of exertion. Sukuna’s alpha pheromones that he had been able to easily ignore when the fight started were suddenly too much for Gojo to handle, driving him closer to his full heat.
“No, that’s not it.” Sukuna’s brows furrowed as he tried to puzzle out the source of Gojo’s distraction. His brain must have been really scrambled by heat for him to think that Sukuna’s frown was almost adorable .
He could see the moment Sukuna realized what was going on, the curse’s red eyes widening briefly as his nostrils flared.
“You never told me you were an omega,” Sukuna said.
“Why would I have?” It wasn’t something he explicitly told anyone, and with the industrial strength scent blockers he usually used, he was okay with everyone assuming that he was a beta. “Don’t even think about going easy on me because of it.”
“I wouldn’t dream of it,” Sukuna promised. “But should you really be fighting in your current… condition?” Although his words were thoughtful, Sukuna’s tone was anything but.
“Fuck you,” Gojo said.
“You’d like that, wouldn’t you?”
“And you think too highly of yourself.”
Instead of allowing Sukuna an opportunity to continue this unwanted conversation, Gojo expanded his domain, engulfing the both of them in cosmic darkness.
As always, Sukuna answered with his own domain expansion, erecting his shrine in the midst of Gojo’s domain. And yet, for whatever reason, this time Sukuna allowed his Infinite Void to hold.
“You are taking it easy on me,” Gojo accused.
Sukuna held his hands up, all four of them, in a placating gesture. “I just thought you may appreciate some privacy. You’re not a very entertaining opponent like this, you know.”
“Yeah? Maybe I thought you needed a handicap to beat me.” Fuck . As much as he didn’t want to admit it, he was losing strength in his body to his heat, and a wave of dizziness had him almost keeling over.
Faster than Gojo could react to, and definitely faster than his large frame would indicate, Sukuna rushed at him, throwing him into a pool of blood. The sharp smell of iron flooded Gojo’s senses, but underneath it, there was a scent that was distinctly Sukuna : a mix of burning incense and dried sage.
“As I said, not an interesting opponent,” Sukuna said, looking disdainfully down at him.
“Okay, you’ve proven your point. Now are you going to get off of me or kill me?” Either way, he needed to not be pinned down by Sukuna as soon as possible, as the situation was causing an undesirable reaction from his body. If he was going to die, Gojo would rather die with most of his dignity intact. Preferably before he started soaking through his pants.
“You’re not even worth the effort of killing right now.” Sukuna’s expression became pensive as he kept staring into Gojo’s eyes. Although the prolonged eye contact was uncomfortable, Gojo stubbornly refused to be the first one to break and look away. “But you may be worth fucking.”
Gojo scowled at him. “Was this how you courted omegas in the Heian period? Saying you wanted to fuck them after not only insulting them, but also ruining their clothes by soaking them in blood? My outfit was very expensive, too, so thanks for that.”
Sukuna shrugged with the arms he wasn’t using to hold Gojo down. “I could court you properly if you wanted, but I have the feeling that you’re the type that prefers being direct.”
“I’ll have you know that I’m the type that needs to be spoiled properly first.”
“I can spoil you, omega . Keep you sated and want for nothing.” Usually that word would raise Gojo’s hackles, but hearing it from Sukuna…
Why was fucking Ryoumen Sukuna a bad idea again? The King of Curses was a more than desired mate, capable of siring strong offspring, and Gojo really needed to stop allowing the omega side of his brain to think for him.
“What do you say? I can help you through your heat, and we can continue this fight some other time,” Sukuna purred.
When did his throat get so dry ? Gojo wanted to say something, anything , in response to Sukuna’s proposition, but he was at a loss for words. Instead, he found himself nodding in agreement to Sukuna’s terms.
Gojo’s face flushed as slick ran down his thighs. He hadn’t allowed himself to experience a true heat since his first, and was entirely unequipped to deal with one. He blamed that fact for how he was practically running into the arms of the first alpha to show any interest in him.
“W-what are you doing?” Gojo asked weakly when Sukuna’s hands moved to undress him.
Sukuna looked at him as though he were stupid. Maybe he was, for wanting to go through with this. “Isn’t it obvious?”
“No, I meant, are we really going to do this here ? Thanks, but getting fucked in a pool of blood is not something I find particularly sexy.”
“A pity. Red suits your complexion so beautifully.” Sukuna looked at him hungrily, and Gojo couldn’t tell if it was because he wanted to eat him or fuck him. Another reason why this was a terrible decision.
“Just… let me take us somewhere else.”
Sukuna finally let him go, and Gojo felt like he could breathe again. Before he could second guess himself, he warped the both of them to one of his mansion. It was a tacky place that Gojo had purchased ages ago just to piss off the Gojo elders by misusing their fortune, but now he was thankful that he had as it was the only place that could fit a fully realized King of Curses.
For a second, he wondered what that must have looked like to their onlookers: to go from being the midst domain clash to the both of them disappearing in thin air. He was not looking forward to explaining the situation to his allies later.
The moment of reprieve he had was short-lived, and Sukuna wasted no time slamming Gojo against the nearest surface, which happened to be a wall. Sukuna was so large that in order for them to be eye-level, Gojo’s feet were completely off the ground, his weight supported by two of Sukuna’s arms.
He’d never felt so small in his life, a feeling that was unexpectedly arousing if how hard he’d become was any indication.
A pathetic whine escaped Gojo’s throat as Sukuna peeled off his blood-stained clothes, letting them fall to the floor and coloring the carpet crimson. The cool air touching his heat-damp skin was a small relief, but when Sukuna immediately latched his jaws onto his exposed neck, the fire growing within him only burned hotter.
“Careful,” Gojo warned as he buried his fingertips into a rather thick bicep, distorting the black line of Sukuna’s tattoo. The last thing he wanted was to be mated to Sukuna because someone couldn’t control where he sank his fangs.
“You taste sweet, Gojo Satoru. Do you think your blood would be just as sweet?” Sukuna asked after he released Gojo’s neck. Red bruises had already formed on his skin in the shape of Sukuna’s teeth.
“Of course I’m sweet. I’m practically an angel.” Well, he didn’t exactly have the morals of one, but he did have enough people try to use that one shitty pickup line about falling from heaven on him that he may as well be one.
“Then let me pluck out your wings and defile you, angel.”
Sukuna then tilted Gojo’s chin upwards with a hand, peering into his blue eyes before pressing their lips together. As he kissed Gojo, Sukuna bit down on the sorcerer’s lips, drawing blood with his sharp teeth. The taste of iron passed between them, red liquid trickling down the corner of Gojo’s mouth.
“As I thought. Like sucking the nectar out of a newly bloomed flower.”
Maybe Gojo should be more concerned about how a cannibal thought he tasted good, but right now all he could think about was how distressingly wet he was, and how desperately he needed Sukuna to fuck him.
As though he could sense how desperate he had become, Sukuna lifted his legs up to his chest, easily folding Gojo in half. A single finger teased his leaking hole, tracing around the edge of the rim before forcefully pushing all the way in.
Despite how much thicker Sukuna’s finger was compared to his own, Gojo’s body readily accepted the intrusion, too turned on to be tight.
“Hah, Sukuna, w-wait. I’ve never—“ Gojo squirmed as Sukuna started to press against a certain spot inside him.
“Don’t tell me you’re still a virgin,” Sukuna said disbelievingly.
Gojo rolled his eyes. “Don’t be stupid. I’ve just never been with an alpha.”
“So I’ll be your first knot? I’m honored.” Just like an alpha to think that his knot was something special.
“Don’t let that go to your hea— oh .” Sukuna chose that moment to stick two more fingers inside him all at once, steadily pumping them in and out of his hole. Each movement dragged more slick out of him, and Sukuna made sure that every inward thrust was angled perfectly to make Gojo’s legs tremble weakly.
Gojo’s knees clamped together as he came, slick gushing from his hole. Fuck, he had basically just squirted on Sukuna’s fingers . Sukuna’s digits were wet as he pulled them out.
Although he just came, Gojo’s erection didn’t flag, and his heat was still ramping in intensity.
There was a time, shortly after Yuuji had swallowed the first of Sukuna’s fingers, where Gojo had thought to himself that it would be funny if along with having extra arms and eyes, Sukuna also had another dick.
Now, watching Sukuna free himself from his robes, that reality was a lot less humorous.
“Not scared are you?” Sukuna gave him a smug smirk as he coated himself with Gojo’s slick.
Well, if he put it that way. Gojo wasn’t one to back down from a challenge.
“Of course not. They don’t call me the strongest for nothing.”
“I wouldn’t expect any less from you.”
But having both of Sukuna’s cocks threatening to impale him at any moment had Gojo realizing that his previous boastful words were nothing more than hot air. Too late for second thoughts now , he thought. Although he was nervous — not scared like Sukuna had suggested— he did want this, and that was more than just his heat talking.
The air froze in Gojo’s lungs as he was carefully lowered onto Sukuna’s waiting cocks. It should be impossible, to fit all of that inside of him, but somehow Gojo’s body gave, both tips sinking into his pliant flesh. His head fell against Sukuna’s shoulder as more and more Sukuna’s cocks entered him, stretching him past the point of comfort. Gojo bit down on the hem of Sukuna’s kimono, the white cloth growing damp from the considerable amount of drool spilling from his mouth.
“Just a bit more, little angel . Don’t close up on me now.”
Finally daring to look down, Gojo saw for himself how only a sliver of Sukuna’s dicks remained, and how his stomach was distended to make room for them, looking as though he had been pupped already.
Gojo shuddered as another wave of his heat struck him just as Sukuna finally bottomed out in his wet hole. Fuck fuck fuck , he mouthed around the fabric. It hurt, being split apart like this, but not nearly as much as it felt good .
“So quiet, for one usually so talkative,” Sukuna teased.
“What do you want me to say? To tell you how big your dicks are and how much you’re stretching me out? No, thanks. You don’t need me to stroke your ego,” Gojo replied defiantly.
“I think I like you more when you can’t talk back,” Sukuna mused.
“Then why don’t you do something about that?”
“I could, but I’d rather hear you beg.”
Whatever witty thing Gojo was going to say was quickly forgotten as Sukuna started to fuck him in earnest. All he could hear were his own breathy moans and the wet sounds of his slick being stirred by Sukuna’s thrusts as he was skewered to the wall by Sukuna’s thick cocks. It took all his concentration not to beg Sukuna to go harder, faster, to be gentler… Each time the head of Sukuna’s dicks hit his sweet spot, Gojo’s eyes would roll back even further into his skull, his toes curling hard enough to hurt.
All it took for him to come again was Sukuna wrapping his fingers around Gojo’s neglected cock, Sukuna’s hand was large enough to engulf most of his length. Gojo clenched down almost painfully as he rode out the tremors from his orgasm, forcing Sukuna to slow down. Their lower halves were both drenched in his slick.
But, Sukuna wasn’t stopping. Once he was able to again, Sukuna continued fucking Gojo at a pace that was possibly even faster than before. Every nerve in Gojo’s body was aflame as he was mercilessly overstimulated.
“Sukuna, p-please… S-slow down, I can’t…”
“How wonderful your pleading is, Satoru. You’re taking me so beautifully, as if you were made for this.”
“Please, please, please…” He didn’t even know what he was asking for anymore, only that his pleas were falling on deaf ears. All Sukuna was interested in was using Gojo’s body for his own pleasure, and that happened to be exactly what Gojo’s body needed to ease its heat.
“Who knew the strongest sorcerer is such a sweet omega?”
“I’m m-more than just an omega.”
“Indeed, and it only makes you all the more perfect.” Some part of Gojo preened at the praise, coming from the one individual who he could recognize as his equal. That same part of him was screaming at him to stake his claim on this strong alpha, to let Sukuna bury his teeth in his neck.
“Alpha, please . I need you to fill me up. K-knot me.”
With a low growl, Sukuna slammed Gojo’s ass down onto his cocks one last time, his knots swelling and tying them together as he spilled deep inside Gojo.
Gojo’s vision went white, and the feeling of being stuffed full with Sukuna’s warm seed and throbbing knots as he was pushed into a mostly dry orgasm. His body simply had nothing more to offer, his heat slaked for now.
He whimpered tiredly when Sukuna moved him from the wall, walking slowly while still inside him, the knots tugging roughly at his rim.
“Which way to your nest, little angel?”
“I’m not small, you’re just freakishly large.” In fact, Gojo was taller than nearly every alpha he knew.
“That doesn’t answer my question.”
“Honestly, I don’t remember.” He rarely visited the mansion, its appearance too gaudy even for him. “Probably somewhere there.”
One extraordinarily uncomfortable walk later, Sukuna plopped them both onto the first bed he could find. While his mind was still relatively clear, Gojo wanted to ask a question that had been burning in the back of his mind.
“What happens to us after?”
“We continue our fight until one of us dies.” Which was exactly the answer he had expected, but to hear Sukuna say it so plainly…
“Doesn’t that seem pointless to you?”
“In what way?”
“Just, finally meeting an opponent that’s interesting only to kill them after a single fight.”
“Perhaps. Would you rather I keep you as mine? To fight as much as our hearts desire?”
“Heh. Aren’t you getting ahead of yourself, proposing to me like this? I’d like to be properly courted first.”
“Then let me offer you the world, Gojo Satoru.”
