They met at a shrine.
In the lull between killings, Sukuna swiped the blood off his face. These sorcerers were weak. Every last one of them. He was leagues ahead of them and their techniques, possessed multitudes more cursed energy than them. And yet they still came, their little families that they coveted taking turns coming at him. It was a waste of time to challenge him.
He would call it a waste of talent, but many of them possessed none. The ones that did, they knew it before he snuffed out their life, received a small bit of praise and recognition before they ceased to exist. Had they let him be, they would have lived fine. At least, for now. He would turn the world of sorcery up on its head and smash it eventually. They knew this and this is why they tried so much, though discretion would be part of their undoing.
And then there was one that approached with perhaps more cursed energy than those already dead today combined. Cursed energy that matched his own, in a way. It lacked that sinister touch, that overwhelming evil presence Sukuna possessed but it didn't hold the ridiculous righteousness that so many came with. The power that loomed made the King of Curses grin. Perhaps this was something that was worthy of his attention now. Sukuna knew it was a Zenin as soon as he entered the shrine. The presence of the boy held the air they all did, but more subdued, as if he didn't care for whatever it is they held. Regal, aware of his power. This was all he knew about this boy, the air of mystery having a heightened effect. Sukuna was thrilled. His pheromones began to permeate the air, excitement for the fight, for the kill. Excitement to sink his teeth into this boy's throat when he died. That quiet confidence he possessed assured Sukuna that it might even be a tough battle.
The boy did not come charging in. He did not attempt to hide himself. He merely walked up the steps of the shrine to its apex, approached with quiet footsteps. His feet seemed to glide when within the shadows that swirled in the area, and it made Sukuna question if this was part of his innate technique. What could he manipulate? What would Sukuna learn? "Well, aren't you the runt of the pack." He was slim for a Zenin, average in height. But Sukuna was already becoming larger than life as his cursed energy grew, as if his body had to extend to hold it all. He was nearing seven feet tall, his muscle mass doing nothing to slow him down. If it was a matter of physical strength alone, he could crush the boy underfoot. But something told him he wouldn't get the chance.
Bright green eyes watched him. "You look like you have to shit with the bears." His voice was monotonous. He seemed bored, as if he would rather be anywhere else but here to face Sukuna. Sukuna laughed, if only because he was taken off-guard. He did not fear Sukuna at all, and that was exciting on its own. Even the ones that acted like they weren't afraid were one heavy footfall from radiating fear in their scent. From the boy, there was nothing.
And then he was taken fully off-guard; the boy threw his outer garment and suddenly he was gone without a sound. His cursed energy was nowhere to be seen, and yet the presence was… Everywhere? The hairs on Sukuna's neck rose as his grin grew. He narrowly moved out of the way before the boy emerged from the shadows behind him, sword in hand to swipe and slash. It was rare that Sukuna felt glad to have his spear in hand, the tool much more useful now than ever before to keep those attacks at bay. The boy was abnormally fast much like Sukuna was, even for someone so slim. "Orochi." The word was barely a whisper behind him, and for the first time in many years Sukuna found himself restrained and airborne, a beast wrapped around his body and holding him as if he weighed nothing at all. Before he could slash the serpent to bits, it was gone, his body falling back to the stone with a heavy thump. The Zenin boy was there, squatted over Sukuna's chest while the man caught his breath, the same disinterested look on his face. "Are you ready now?"
It would be a lie to say Sukuna felt something akin to love at that very moment but he certainly wanted to fuck the boy within an inch of his life before he killed him, perhaps after just for good measure. The fact that he caught the scent of his pheromones did nothing to quell that desire. He stank like an alpha, but he also reeked of a meal which made Sukuna's fangs ache. Ginger and something reminiscent of the woods in spring. "Zenin…"
"Megumi."
"Zenin Megumi. You'll eat those words." Mild shock rose on Megumi's face once his throat was grabbed, pinned to the ground once their positions were swapped. Megumi melted into the shadow again and Sukuna fought the desire to sigh.
Their fight was a dance accented with their will, set alight from the clang of their weapons, punctuated with their striking blows and their moans of pain. The shrine was turned to complete rubble before the pair chose to cease their battle. The fight still thrummed through Sukuna's veins, cursed energy nowhere near depleted. But Zenin Megumi was the same. The thrill of battle was still in his eyes, even as he stayed back and away, even as he looked ready to pounce again. "Choose a better place next time," were his parting words, melting into the shadow much like before.
Sukuna would blame that little move for not having murdered the boy. There was no other way, ample cursed energy or no. But he was excited to fight Zenin Megumi again. A worthy opponent was rare to come by, and for the boy to have survived? The desire to see— to face— this sorcerer again was heavy on his mind.
—
They met again on the Zenin grounds.
Because Sukuna was about as subtle as a tsunami, as quiet as a beating drum. It did not take him long to lose his patience. A month was long enough to improve his abilities and test himself again. "A better place," Megumi had requested, and what better a place to defeat him than in front of his family instead of in isolation, away from prying eyes? The ranks of the Zenin came running as soon as he set foot beyond their gates. He was ready to slice and dice to make his way to the opponent he desired, but it proved unnecessary; though they were ready to attack, upon seeing Megumi emerge from the shadows cast by moonlight, the small army held still. They remained surrounding the two, Megumi sitting cross legged on the path. His fist held his chin up. "Zenin Megumi." The boy's name was practically purred. He was annoyed, and somehow that brought a bit of glee to the pit of Sukuna's stomach. There was an emotion there.
"This is what you consider better?" There was annoyance in his voice, and Sukuna saw that as complete ire rather than simple annoyance. He imagined it was difficult to rile this one. But something was off; his energy was hidden. Subdued. He appeared weak.
"Are you ready?" Sukuna was ready to pounce immediately, much like the boy would. Megumi moved to stand just as another regiment of weaklings arrived, along with a much older man. Sukuna scoffed, he could see the posturing even from this distance. He watched as Megumi frowned and bowed his head, took several steps back. Sukuna was beginning to understand.
"Ryomen Sukuna—"
"I don't have the patience to listen to you grand stand. I'm here for the boy." Sukuna was quite a patient man, in reality. When it worked to his desires at least. But someone getting in the way of something he desired? Such a thing did not exist.
Not for long, at least.
The man looked over his shoulder to Megumi's down-turned head and scoffed. "This mongrel? He is weak." He opened his mouth to speak again. Nothing but a short whimper exited before his body fell to the ground, head severed cleanly from his neck. Megumi had immediately looked up and darted away several feet before the cleave connected with the other Zenin's body. The rest of his body slowly fell apart once collapsed, sliced into several pieces.
"Zenin Megumi, are you ready now?" The surrounding sorcerers and warriors took several steps back, several ran away further into the grounds.
Though he was further away now, Sukuna could see the small smile that crossed Megumi's face before his entire body was overtaken by shadow, melting into the ground.
They clashed and clashed and clashed, Megumi's true power on display again. Sukuna refrained from setting the place on fire, and Megumi refrained from using his shikigami to toss Sukuna around in a way that would utterly destroy his home. At first, at least; Sukuna was not so kind as to not receive a thrill from tossing the boy about, hearing the wood splinter and fly as he flung Megumi through support beams and into solid walls whenever a perfect attack connected. Eventually, Megumi did the same, returned each injury in kind either himself or through the use of his shadow puppets. The onlookers disappeared at some point, no one willing to follow them as their battle traveled and possibly get caught in the crossfire. But Sukuna did not care about that. The more they fought, the less he cared about murdering Zenin Megumi. The more they fought, the more he wanted to test his limits, and test his own. The limit seemed to be nonexistent, and that was something Sukuna didn't believe he'd find in someone else. It was startling. It was delicious.
But all good things must come to an end. It was as if the wind was knocked completely out of Megumi with Sukuna's last strike. His cursed energy was there but fluctuating, erratic. If he was close to death, it wasn't an uncommon occurrence. What made it odd was the suddenness of the change. Sukuna approached his fallen body, nose picking up on Megumi's pheromones immediately. It made his eyes water and made him want to sneeze. It made his tongue burn. Almost completely different from his scent an hour ago.
Megumi sat up from the rubble sluggishly, cursed energy radiating from his body untethered. It was flamboyant and wasteful, and it was clear as day now that the boy was falling into rut. Without an omega around, no less. What a strange boy. He charged at Sukuna without any tact and was immediately restrained. He had no control over the primitive part of his brain. It spoiled the fun. Megumi flailed as much as he could with his arms restrained, legs thrashing in an attempt to get away. He growled and snarled and snapped his teeth as he looked back at Sukuna, fangs poking out from behind his lips even as his jaw was clenched tightly closed. "Is this how you die? At the mercy of your body and unable to defend yourself? Pathetic." All Megumi could do was shiver in Sukuna's grasp as he panted, his thrashing seemingly more like writhing the longer he continued. His rabid pants devolved into short gasps laced with pleasure.
Well, he did want to fuck the boy to death last time.
"We will have our rematch. Properly." Killing small fry was never an issue for Sukuna. And had this been anyone else, perhaps he wouldn't have stopped; perhaps he would have let them charge right into his cursed technique and die. He would not have batted an eye, would simply have moved onto the next opponent. But it was too much of a shame to let something— someone— so good go to waste. And beside that, Sukuna wanted a taste.
Sukuna was not gentle with Megumi. Clothes were torn to shreds by sharpened nails like claws, tossed aside like inconsequential garbage. Megumi didn't fight his instinct and remained in it, thrashing and beginning to fight Sukuna's hold on him again. Briefly, Sukuna wondered what Megumi would do if his rut was not in the way, but the reality was that this would not have happened. There was no reason to be delusional.
He wasn't sure what he expected; there was lithe muscle and scarring that seemed less from battle and training and more from being beat. But for his pretty ass to be plugged seemed a bit… Megumi was in no position to answer even if Sukuna asked, and he didn't much care either way. Keeping him pinned to the floor by his large palm set at the small of his back, Sukuna tugged out the meager plug and tossed it aside. Megumi continued to squirm and thrash, kicked his legs out in an attempt to kick the giant behind him. His teeth gnashed and he fought with physical strength that should be beyond such a scrawny body in comparison to Sukuna. But it wasn't enough. His teeth gnashed, slobber falling from his lips as he was nearly feral. "If you want to get away so badly, there's plenty of shadow for you to fuck off into like you usually do. Or you can send those dumb rabbits you like to toss in my face."
Instead of using his hands to do anything useful, the boy attempted to pull himself away. It was unfair, but Sukuna didn't care. Megumi was weak now. "I— I— I don't—" he continued repeatedly, growls and whimpers filling the air between them. It did nothing to keep Sukuna from shoving his tongue into his hole, and two fingers that stretched him wider than the plug he had in there. He wouldn't fit without it. Still, he thrashed through it, cried out each time his fingers pushed forward, each time they stretched wide. The boy was in pain but what else did Sukuna have to offer?
Each inch of his cock that slowly pushed into Megumi was met with resistance, met with more of his efforts to escape. And Sukuna kept him pinned with that singular hand at the small of his back, the other too busy guiding his erection into his hole that was not stretched nearly enough to accommodate Sukuna's girth. But he would live, or he wouldn't. It didn't matter if he was torn in half. Despite his reassurances, Sukuna found he didn't care. Sukuna's slowness was for his own benefit, the extra saliva he spit down on his cock to ease his entry. The tightness was good but he had no desire to chafe his dick.
Each thrust forward into Megumi was like having a small taste of heaven, a little piece of the skies falling apart to drop liquid heat onto his spine. The snarls and snaps of Megumi's jaw only made him laugh, only made him take his pleasure with more ferocity. "All that power and all you can do is snarl like a mongrel," Sukuna purred. Having so much power over someone he thought— almost thought — was his equal was intoxicating. No amount of wine would compare. Soon, the boy grew quiet and Sukuna thought perhaps he was unconscious. Leaning forward, he heard the whimpers from him, the change in tone that took hold of his voice and his attempts to hide it. And Sukuna only laughed harder. His free hand took hold of Megumi's hair as he leaned forward. He turned the boy's head to the side, took in his tear-stained and reddened face. Green eyes were glazed with tears, the lower half of his face covered in a mix of his tears, snot, and saliva. And yet he was now fighting pleasure. Sukuna licked the side of his face and laughed as soon as Megumi whimpered, enjoying the shiver that wracked the body beneath him. "What a mess you are. You're being raped and demeaned during your rut and you're enjoying it? I'm not sure if I should call you weak or deranged, but you're clearly not as weak as I expected at this point, little blessing. But it is pathetic." Megumi's mouth fell open, his eyes squeezed shut as Sukuna continued to fuck him. He held nothing back, each of his thrusts bearing his full weight, the only thing keeping Megumi's body from traveling across the floor was the pressure of Sukuna's hands keeping him still. His voice was harsh against Megumi's ear, despite the pleasure he felt and nearing his peak. "Maybe this is a perfect rematch for you, a fitting end. All that fight in you just to be bent in half and fucked to death by someone you thought was your equal."
Small hurt noises continued to flow from Megumi's mouth, even as his body spasmed, the air punched out of his lungs as his hole fluttered around Sukuna's cock and nearly pushed him over the edge. "Please," he managed to get out, fingers digging into the floor once more.
"Please what? Stop? Greedy whore." Sukuna kept him pinned there and chased his own pleasure, ignoring Megumi's further cries. Whether it was to stop or to continue, he didn't care. He didn't stop until Megumi was filled with his release, sweat on his forehead and neck beginning to cool. Megumi quieted and stilled, heavy pants visibly causing his body to shake. But he was conscious and alive, despite the blood mixed with the cum staining Sukuna's cock. It made Sukuna feel odd, something he couldn't place. He felt a desire to stay right there for a while longer, to listen to Zenin Megumi catch his breath; to watch his features return to their pale luster under the moonlight, and to taste that spike in his pheromones again.
It felt gross.
Sukuna retreated quickly, left Megumi there like a used rag and for once he actually felt like he was running away. Not from the rape, but from the disgusting sensation he felt after. Of wanting to be soft . There were just some levels he'd never stoop to, or so he told himself. But the very idea of Zenin Megumi began to haunt him after that— a powerful sorcerer that could actually be his equal, if he learned not to be a slave to his anatomy. But he was young, it would come with time. He still lived and breathed and no one in existence would ever be perfect but—
It felt gross.
—
They met again within a temple bath, empty then save for Sukuna and several corpses. Once again, Zenin Megumi sought him out, several days after being left behind. Halfway across the country from the Zenin grounds, he emerged from the deep shadows that encompassed the bath. Sukuna sensed his presence before he saw him and he did not startle, did not flinch once he sat on the edge of the basin. Sukuna had been startled enough by the sight of the boy in his dreams. "If you're here to attempt to get revenge—"
"I never—" Megumi paused and hunched over, elbow on his knee. "I didn't fight you in the first place because I wanted to kill you." Though Sukuna was curious, he showed no change in expression. Naive brat. "If I wanted you dead, I'd kill myself and take you with me."
Sukuna scoffed, shifted in the bath. The boy had nerve but he believed he had a trump card that Sukuna wasn't privy to. Megumi could kill himself, but he wouldn't kill Sukuna, no matter how much confidence he had. "You are certainly welcome to try, but anything you throw at me I can conquer, brat. Why are you here?" Sukuna wanted to be agitated, but he was pleased to see Megumi in one piece. He wasn't fragile and frail and broken. He was strong, even when he did submit.
"To keep testing my own power. I want to kill them all so I imagine we're not much different. But you made things a little more complicated. And better. So I came to thank you, I guess." Sukuna remained quiet, waited for him to continue. His eyebrow arched in question. "My uncle is old and ill. You sliced my cousin to pieces, which leaves me as heir for now. I was supposed to be sold to the Gojo after my first rut, but now they can't sell me until some of the others are older and present as alphas. And I'm exclusively despised in the family so they'll all try to murder me in the meanwhile. But as long as I can kill the Gojo heir, I don't care." He hummed briefly. "And there's the fact that they don't know I had my rut, thanks to you as well."
"That looked more like a heat than a rut." It was a mere insult, but he watched for Megumi's reaction. Though his face remained blank, he could see the barely-there shiver in his body and the subtle flare of his nostrils. The desire to shove Megumi down and take him while he was in his right mind rose and was immediately squashed. "I've never heard of an alpha being sold into slavery."
"Some nonsense about fate. Sold and bitched and bred, with the guarantee that any children with Zenin techniques be given back to them. Because the Gojo are rich, have always been rich, and always will be rich. And the Zenin will always be greedy and always care about tradition and image. Can't keep an omega with a heavenly restriction, can't keep a bastard child, even if it has your cherished technique. I'm as much of a blight as my mother was but they couldn't kill me and I wouldn't just lay down and die."
"Then kill them."
"I intend to. But I can't touch that Gojo heir. Literally."
"And you think you can kill me over him?" Sukuna bristled at the thought.
"In a heartbeat."
Sukuna grunted and stood from the bath. "If you're not here to battle, I have no reason to suffer your presence." Though Megumi smiled, he melted away, presence dissipating quickly. If Sukuna took some time after that to look into the Gojo family and their special, googly-eyed heir, no one was any wiser. So no, he did no such thing and no one could prove otherwise.
—
They met once more at the Zenin grounds. Sukuna intended to set the place on fire and intended to murder every soul there. Instead he found Megumi, curled up in the servants' wing with a book. The servants that he passed ran away at the sight of him, some tripping over their feet to get away as swiftly as possible. It took a while for Megumi to look up, as if he could not be bothered to acknowledge the monstrous presence beside him. Eventually the book was closed and he looked up at Sukuna. "Are you surprised I can read or something? What do you want?"
"Well, aren't you full of nerve today?"
"And I suppose you're not feeling shy today."
Though Sukuna snarled, he didn't respond verbally. It was true; it wasn't the first time that he had returned, but it was the first time since he intentionally showed himself to Megumi. In two weeks, he had seen no less than eight attempts at the boy's life. Outright battle, poisoned gifts, assassination attempts. One even accidentally killed himself and two servants with a gaseous mixture intended for Megumi. He was strong and intelligent with a healthy dose of paranoia to keep himself alive. Sukuna never felt himself both pleased and agitated with the same person before. He plucked Megumi up from his seated position by his throat and shoved him into the wall, kept him pressed there with pressure on his throat. The book dropped to the floor as Megumi wrapped his hands around Sukuna's forearm, his fingers unable to meet around his flesh. Megumi used his grip to lift himself slightly, to take some of the pressure of Sukuna's fingers off the sides of his throat after several seconds. Held at eye level, Sukuna leaned in and kissed him, relished in the taste of his lips, devoured the light groan that was exhaled into his own mouth. Megumi's legs flailed in the air but soon moved properly, attempting to wrap around Sukuna's thick waist and tug him close, to keep him near. It wasn't until Megumi began to pant through his nose that Sukuna pulled away, slowly tracing his tongue along Megumi's bottom lip after. "You."
"What?" He blinked several times, his thighs flexing around Sukuna's waist. Sukuna found he wanted to see those green eyes filled with tears again.
"You. That's what I want, that's what I came here for."
Megumi's grip tightened. "I'm not an object."
"You say this, yet you're willing to let yourself be sold off and owned by some sorcerer you believe you're weaker than."
"I'm not weaker, but I can't touch him. No one can, yet."
"Then come with me and we'll figure it out. I have no desire to treat you like an object." The words left Sukuna's mouth before they registered in his brain. He was certain the confusion was on his face in the same way he felt it, because Megumi laughed, a full bodied, beautiful thing that made Sukuna's stomach turn in that gross way he continued to feel. It made his hand tighten around Megumi's throat again, and the boy sighed as his eyes rolled and his legs tightened around Sukuna.
A soft moan left Megumi's lips, and the pressure around his throat was released. "Ridiculous," he managed after a moment, eyes blinking several times. "This is mine and I intend to keep it, even if there's nothing but corpses to lead."
"You'd even kill the children?"
"Yes."
The grin on Sukuna's face sufficed to relay his opinion. He set Megumi down on his feet and released his throat. Megumi's hands remained around his forearm and so he didn't pull away completely yet. "I never know what to expect from you." It was a compliment, even if it barely sounded like one.
Megumi's fingers flexed around his arm, his nails gently pressing into the skin. "Then stay with me and figure it out. I have every desire to be with you."
Sukuna's face contorted into a grimace. The idea should have felt completely wrong and it should have been met with an immediate no, but he grimaced because he didn't feel completely opposed to the idea. All because Megumi didn't flinch at the sight of him, could hold his own in a fight against him. All because he encompassed a strength that matched Sukuna's and that was something he never expected to exist, let alone find. He looked down at the younger sorcerer with that grimace, stared like he was debating if he should squash a beetle beneath his colossal foot. "Take what is yours and I'll consider it."
Megumi's lips curled into a feline smile as he released Sukuna's arm and moved away. "Sure." There was no hesitation as he walked away, no hesitation as he moved through his home; there was no hesitation as he entered his uncle's quarters, no hesitation as he used a partial domain to encompass the room in which the aging sorcerer rested. And there was no hesitation as he slaughtered the head of the Zenin family and everyone within the domain who resisted. And all that Sukuna could do was laugh when Megumi took his rightful place in their meeting hall some time after, when his divine dogs sat atop and pinned two naysayers, and when Megumi bluntly expressed he did not care if Sukuna desired to kill them all.
Perhaps he would stick around to figure him out.
—
Their relationship was hardly one at all; Sukuna would come and go, murdering people as directed by his whims and desires as his primary pastime. He would occasionally return to Megumi, to assess his own power, to assess if Megumi had surpassed him yet. Their battles were intense and antagonistic. Their battles were exciting and thrilling, and often wound up being foreplay. This arrangement mostly suited them, and once it didn't, Sukuna found himself there more often, found himself staying longer.
Everyday that Sukuna was there— and even when he wasn't, according to Megumi— one of several Zenin advisors would attempt to shove an omega in Megumi's direction. A cousin; a Kamo; a powerful sorcerer from such-and-such province. Even when Sukuna's head was in his lap while he read, even when he was sprawled across Sukuna's lap like a lounging cat. Even when Sukuna permitted them entry to his— their?— room when Megumi's mouth was too filled with cock to answer for himself. Megumi was young, of course they'd expect an alpha to at least attempt to produce an heir and mate with an omega. Megumi held no interest. Even as the head of the clan, he had to listen to nagging nannies talk at the very least, even if he didn't follow a word of what they said. In the same way that Sukuna had no interest in anyone but Zenin Megumi, he had no interest in anyone but Sukuna.
Eventually the assassination attempts began again. Megumi did little to antagonize the younger members of the clan, but that didn't keep the rest of his family from wanting him dead or at the very least weakened. It was like Megumi said: the Zenin despised him. They wanted their traditions and their money, not this youth who defied the usual actions of the clan head. When Sukuna was there, he readily tasted his food for poison and when he wasn't, only Uraume prepared and delivered meals to Megumi. It was a waste to leave his subordinate behind, but part of Uraume's duties was to handle anything Sukuna deemed worthy or precious. If Megumi wasn't at least one of those things, then there was likely nothing in the world that was.
In all this, the Gojo were quiet. With their deal in shambles, they seemed disinterested in any private communication with the Zenin. There was no point in attempting to regain Megumi for their heir, and they were intelligent enough not to bother.
Within a year, Megumi's will had changed. More and more, he seemed less and less interested in his idle ideals, less interested in keeping his title. He grew a little darker, grew a bit less neutral in his cursed energy. When the Gojo sent an assassin into his home, his shift in personality seemed severe. Neither he nor Sukuna was sure if it was for Megumi or Sukuna, but the reality was that it didn't matter. If someone came for one of them, they came for both of them. Despite it being a feeble attempt, it was enough to piss off Megumi severely, while Sukuna remained amused. Because what difference did it make if a dumb sorcerer's pet failed to kill either one of them? It only led to Megumi being frustrated, led to him angry pacing for longer than Sukuna would have liked. "It's because it's deliberate and calculating and they want something. They ignore our existence and suddenly they make this weak attempt?"
"Blessing—"
"Gojo could kill you."
It was that insistence that gave Sukuna pause. Because that seemed to be the only thing that terrified Megumi, ever. It was a weakness, but in reality Sukuna held a similar weakness and couldn't hold it against Megumi. Despite their closeness, it was decently hidden from outsiders, hidden from those that could possibly use it against them. But who could use it against them when they were so powerful? The Gojo clan, apparently, and their chopstick build heir. While Sukuna had investigated the family, he still didn't quite understand what was the big deal; Six Eyes could see "everything," could weasel his way into anything and come out unscathed. He was larger than life and some other such nonsense, and yet curse users and cursed spirits ran rampant and he did nothing to change the tide of things. They trembled at the sight of Sukuna, not at the Gojo name. And yet, the Gojo sent a weak, mundane human to the Zenin estate to, what? Attempt to poke a small dagger into Megumi's heart? Because such a small thing would have no effect on Sukuna at this point; within a year he had grown two new arms and grown another foot in height, and another two eyes that he could control independently. He had even grown another penis, which Megumi was thoroughly amused by but could not handle taking, considering he could hardly handle one. Perhaps it was deliberate and calculating, and it was beginning to frustrate Sukuna that perhaps Megumi was right. They were missing pieces to the puzzle. "I'm beginning to see, I think."
"You ought to, four eyes." Sukuna snarled and tugged Megumi into his lap, laughed as he bit Megumi's throat and elicited those sweet sounds from him. He wasn't pushed away, Megumi simply going limp in his arms. "Mate with me," he eventually muttered, fingers traveling through Sukuna's hair. It was long again, the desire to chaotically cut the pink strands outmatched by the desire to feel Megumi's hands in his hair.
"You are an alpha, and I have no desire to possess you like an object." Mating between an alpha and an omega could be romantic, but was often only used as a tool or a political arrangement. It meant ownership to many omegas and nothing more; their safety wasn't even guaranteed. Outside of these high and mighty families, the practice was dying out.
"I own you; you're mine. Why shouldn't I be able to feel it, too? Why shouldn't I be able to feel connected to you? Why shouldn't I belong to you as much as you belong to me?"
Much like the first time they met, Sukuna laughed, taken off-guard. Megumi never fought a single feeling or desire he had; why would he fight them now? Sukuna was still learning. His heart beat rapidly as he grinned. "No fear of dying now, little blessing?"
The curl of Megumi's lips was a bit more tame, but it was enough for Sukuna to know he felt the same. "Doesn't that make it thrilling? Maybe you can actually kill me now. And if I do die, feel free to kill the rest of the family, too. I'm sure it'll be cathartic."
—
The nature of bitching required a lot of cursed energy, as did mating. It was easy to die during the mating process alone with a careless alpha, but bitching required repeated knotting and biting until the mating bite took, until the new omega's scent changed, and then until their scents were joined. There was no time to recover, or else the process would have to be repeated. The process forced the body to adapt, to take on the qualities of the gender it was not; if there was no reason to remain an omega, the body would not keep its transformation. Sukuna's ability to use reverse cursed technique was a boon in this case, but it still didn't guarantee much. The pain and damage were part of the process, and so there was only so much he could heal Megumi.
Knowing this, Megumi wasn’t deterred. By Sukuna’s hand, he fully accepted death. This pleased Sukuna and in this way, he believed Megumi was stronger than him; he had no intention of accepting death at all. It took a strength of mind he did not have yet, because he was a greedy bastard that wanted everything in life. His own death was an implausibility.
To avoid being interrupted, they left the Zenin grounds for an isolated and deserted shrine, small and hardly worth the trek for upkeep. It was unnecessary to hide, but the desire to do so was still there. It wasn’t like Megumi’s first rut where they would scare off everyone from his shouts of pain by battling beforehand. They skipped the ritual bath that was often given before these events and stripped down beside the shrine. Despite his resolve, Megumi’s hands shook as he removed his clothes in a hurry. “Nerves,” he said, his smile small as he clenched his fists.
“I’d expect no less. You’re not the kind to just lay down and die, my blessing.” It took an immense amount of willpower for Sukuna to be gentle with Megumi. They were never truly gentle with each other when it came to sex. The moments of life in between, they didn’t much need to either. Affection was usually accented heavily with violence, snark, and force until they settled down. But each of his massive hands were gentle now as he dragged Megumi into his arms and settled onto the bedding they brought with them.
Each kiss and bite laid reverently across his skin made Megumi sigh, his body shaking beneath Sukuna’s as he rested flat on his stomach. “Could you stop treating me like I’m actually going to die?” A soft laugh followed as he looked over his shoulder at Sukuna’s towering form. There was a slight sour tone to his scent, a souring due to fear but far from overwhelming. "Or like I'm weak? That would be worse but I'm giving you the benefit of the doubt." Instead of giving a proper answer, Sukuna sank his fangs deep into the skin of his neck, Megumi shouting from the pain of it but immediately going limp. "Much better," he said on an exhale, a short whimper following. One set of hands kept Sukuna's balance as the other set lifted Megumi's hips and spread his cheeks wide with his thumbs. They brought oils along with them, but the possibility of this being his last time with Megumi meant Sukuna would taste as much of him as he could before then. His tongue traced slowly from his sac to his hole and back down again, saliva quickly coating his skin. Once Megumi's hole relaxed and unfurled, Sukuna's tongue pressed in deeply and fucked his hole ruthlessly until tears filled his eyes from orgasm, until he attempted to crawl away from Sukuna's mouth.
Sukuna was careful about stretching him open and took his time, even if the edge was taken off and his tongue had done a lot of the work already. Under normal circumstances, they both would have been impatient by now. Megumi would have kicked and fussed and rolled over if Sukuna hadn't already shoved the entire length of his cock deep inside of him. But today the excess stretching was a necessity. His cock was as thick as Megumi's forearm, and his knot would be worse. Today, Sukuna was slow and deliberate as he entered Megumi, slow and deliberate as he wrung out as much pleasure as possible from Megumi, brought him to his peak again and turned him to mush.
The first time Sukuna's knot swelled, Megumi thrashed and attempted to pull away. His fingers dug into the bedding like claws, his knees scraping against the surface while Sukuna held him still. "Too much," he said with pained breaths, unable to get away from the stretch of it. But Sukuna's hands held tight and kept him from moving too much, kept him from causing himself more pain and tugging his knot. Once his teeth sank into the gland at his neck, the thrashing increased as instinct kicked in; Megumi snarled and snapped, reached back to sink his nails into Sukuna's hair and yank and pull and tug with as much strength as he could muster. Sukuna felt the burn at his scalp, felt a piece of his skin tear away from his head with his hair. He had almost forgotten how strong Megumi was on his own, without a drop of cursed energy augmenting his abilities. And once Sukuna's fangs were immersed in cursed energy, Megumi's cursed energy ran rampant in response. He continued to move like a feral beast, managing some movement even with Sukuna's arms wrapped fully around him. Even in such a petite body in comparison, Megumi found a way to manage. He clawed at Sukuna's arms, kicked his legs out against Sukuna wherever his feet and legs could reach, and even tried to headbutt the giant from behind. But it was pointless; they would not stop until it was over.
After the first round, Sukuna healed Megumi's hands and his throat, and some of the tearing he sustained from attempting to escape his knot constantly. But they continued on. Round two was just as bad, Megumi's cursed energy responding with more ferocity. Shadows cast by the trees that surrounded the area swirled and spread, taking on the shape of a giant wolf's maw. Surges of cursed energy buffeted the shadows away repeatedly, kept them both safe from the wolf's teeth.
Round three and four and five were much the same, each time defending their bodies and healing Megumi by small amounts. In hindsight, had Megumi been less strong, had he held less cursed energy, perhaps it wouldn't have taken so long for his body to submit. Perhaps it wouldn't have taken so long for his cursed energy to dissipate and change, for his scent to smell more of ginger and less of spring saplings in the woods. Ginger and the winter flower garden. By the time Megumi had gone completely limp and unconscious, the scent of camellia was laced with the musk of incense, the scent of him making Sukuna serene. There was a brief moment of anxiety in the pit of his stomach that disappeared quickly; Megumi's heart still beat, his breaths were pained but still he breathed.
Perhaps it would have taken less time for Megumi to change had he been weak, but perhaps he would have died. "Maybe you really are perfect for me," Sukuna said, pressing his lips to Megumi's temple.
"I hate you, you overgrown fucking bear," Megumi murmured, barely conscious. He turned his head to gently nuzzle Sukuna's cheek and purred, and immediately settled back into unconsciousness.
Sukuna was beginning to truly believe that there was nothing in this world that he wouldn't destroy, wouldn't give up for Megumi. There was nothing in this world that was good enough for him, but while they still lived and breathed, it was a good place to start.

It took a month for either of them to notice any overt physical changes. It was Sukuna first, his abdomen gradually forming a scar. "If I suddenly have a pussy for a stomach, I will murder us both," he told Megumi as the scar became more prevalent, more noticeable. It was Megumi that was supposed to transform, not Sukuna. They shared in each other's cursed energy and that was all. That was what would be the usual effects of mating. Though Megumi laughed at the idea of a vagina stomach, he did look concerned.
Each day, Megumi's body felt hotter, his abdomen hurt with cramps, and Sukuna hoped all he was having was sympathy pains and a sympathy scar that would disappear as soon as Megumi's transition changed. His stomach felt like rot, felt like worms writhing at all hours of the day and night.
And one morning they woke to find subtle lips open where his navel used to be, the tip of a huge tongue poking out. Megumi laughed and laughed and laughed all day, but Sukuna held the last laugh by the time they went to bed, Megumi's curiosity getting the best of him and grinding down on that tongue like a bitch in heat. His hole had never been so wet, now suddenly capable of producing slick in copious amounts. He rode Sukuna's belly until he passed out, and over the next few days if Sukuna even hinted at mentioning it, Megumi caused his own shadow to cover his mouth or choke him. The choking generally led to more fun, but either way Sukuna was thoroughly amused. Once Megumi could think of the new mouth from his belly as something more than just another piece of Sukuna to ride, he went on to investigate the body part. It did not have a mind of its own from what they could tell, but it was easy for Sukuna to forget about controlling it, the tongue occasionally hanging out slightly. However there were times when Megumi would pass by close enough and that tongue would dip out to lick him of its own volition.
But Megumi was more interested in where it went. Because it didn't lead to Sukuna's stomach, that much they were both certain of. It only took a few days before Megumi pried the mouth open and crawled inside, much to Sukuna's dismay. The sensation was uncomfortable, and it sent what felt like lightning blasting through his brain for a moment. Minutes later, Megumi did not reappear, and Sukuna attempted to reach inside, but his belly mouth remained screwed shut. "Really? You're part of my body and you're refusing me? " For all its stillness, it might as well have turned back into a scar. Sukuna knew Megumi wasn't dead, could still feel his existence in his soul, but the concern of not knowing what was going on was still there.
Another minute and the mouth reopened, Megumi's head popping out. The tongue remained lolled out, giving Megumi something to lean on as he propped himself out. "It's mine," he answered after a moment, speaking as if it was completely normal to have crawled in there, and completely normal to just dangle out of Sukuna's belly.
"All of me is yours, so explain."
"It's a part of my shadow. Or connected to it. I'm sure you'll learn how to use it in no time to do as you prefer, but when I go in, I'm traveling through shadow, through my own and through yours. Maybe from far away, too." They left it at that for now, Megumi's physical ailments soon picking up once again. They had forever to learn what all was new between them.
Several more days passed with Megumi's pain increasing; his cursed energy fluctuated with it, he spent more time in bed, and had very little appetite. Sukuna wasn't worried, and he would always swear that he was not, but he must have come off as worried enough that Uraume repeatedly told him it was normal. As if Megumi would die now of all times, after already going through an act worse than death. Sukuna would kill him first.
On an early morning, Sukuna woke up to Megumi rolling around like fallen leaves in the wind before completely stripping down. He grunted all the while and immediately crawled out of bed, as if getting away from the bed would solve everything while the moon was still high in the sky. His scent was off, very off, and Sukuna's nose tickled with it. His tongue salivated, and it felt as if he had taken a bite out of raw ginger, the sweet and peppery warmth of it smacking the back of his throat without giving him the desire to sneeze like when Megumi was an alpha.
Megumi didn't get far on his hands and knees, Sukuna's reach was much farther than an average-sized human. He took hold of Megumi's ankle easily, surprised by Megumi's swift reaction to turn and start kicking. Just as quickly as he started, he stopped, laying flat on his back and shivering. "It's too hot," he practically whined, arms splayed across the floor. Sukuna ignored him and pulled his legs up by their ankles, spreading him open. Behind his balls and half-hard cock were several new folds of skin, glistening with copious amounts of slick.
"Would you look at that? It looks like you're fully presented." Megumi shook his head and Sukuna chuckled. "No? You're wetter than a river, blessing."
He continued to shake his head, attempted to kick Sukuna despite the fact that his ankles looked meager in Sukuna's hands. He had a better chance of moving the rest of his body using Sukuna's grip as an anchor. It wasn't anything new that Sukuna was so much larger, but with him fretting like this, Megumi looked smaller. Sukuna's second set of hands moved Megumi's thighs to press against his chest. Though he squirmed, he didn't bother trying to kick once his ankles were released. "I don't care, it's hot."
"I bet." It was all the warning Sukuna gave before sliding Megumi's body into his lap and holding him upside down to dive into his new cunt. His arms remained wrapped around his waist, and his free hands supported his thighs to keep them open and still. There was the desire to just fuck Megumi senseless, to have him scream and cream over and over again until he was a sobbing mess. But first and foremost, he wanted a long and thorough taste of his mate.
Though Megumi attempted to flail at the first touch of Sukuna's tongue against his new lips, he also gasped. His sex was hot and swollen against Sukuna's tongue, his slick a pleasant sweetness to his taste buds. The flat of his tongue pressed teasingly against his folds, gently allowing Megumi to get used to the sensation. It was new, and with all eyes open, Sukuna looked down and watched all of the omega's reactions. What seemed like discomfort quickly switched to something more relaxed. His abdomen twitched beneath Sukuna's arms with each slow swirl of Sukuna's tongue, his holes clenching around nothing but dripping more slick from pleasure. In no time at all, his cock was hard, twitching and jumping once that tongue dipped into his cunt properly and slowly fucked him. He was teasing; he knew it and Megumi knew it too, small disgruntled noises paired with his soft moans and gasps of pleasure. Soon his thighs shook with the desire to throw Sukuna off more than involuntarily, his hands reaching up to scrape and scratch at the thick arms around his waist. Precum dripped in rivulets on his abs and down Sukuna's arms, slowly headed over his chest with sweat. "Sukuna, I swear I'm going to murder you," he growled softly, the impact completely gone with the moan that followed. Eagerly, Sukuna used the full length of his tongue to fuck his cunt, moaning softly as more slick coated his tongue. One hand left Megumi's thigh to wrap completely around his cock, slowly stroking at half the pace in which his tongue moved. "Suku— fuck— naah —"
The shadows around them swirled and slowly sank back into the floor repeatedly. Each time they would flick around and bubble, occasionally touching both of them, eliciting small shudders of pleasure from them both, Sukuna's moans of delight just a bit louder, a bit deeper than Megumi's. It was new and it felt better than he would have thought. Playing in his shadow was another thing they'd have to try.
Though Megumi had no control over it in the first place, soon his cursed energy was completely out of reach, the shadows stilling completely. He squirmed and writhed, his thighs trembling with his failed attempts to keep still. " Haaa, please. Please, more, please, plea—" He continued to beg between harried breaths, his moans increasing in volume. Sukuna was enjoying keeping him like this, just on the edge of cumming, his cock swollen and throbbing endlessly in his hand. But the desire to see him unravel was greater, and he quickened his strokes over Megumi's cock, kept his tongue buried deep inside of his cunt as if his tongue could reach his womb as-is. Megumi held onto Sukuna's forearm, toes curling in the air as he reached his peak. Sukuna didn't bother to change the angle of his erection, instead watching as Megumi's seed landed on his own face and into his open mouth. The first drops made his body jolt and his mouth close mid-moan, his body shuddering with intensity. His control and care left quickly, unable to keep his mouth shut and himself quiet. His holes continued to spasm, pushing out more slick and making a mess of Sukuna's face and neck. And Sukuna continued to stroke and coax, continued until Megumi whimpered and flexed his free leg to shove his heel against Sukuna's head. He stilled his hand but kept his tongue buried deep until Megumi actually kicked him, repeatedly. "You fucking dog, quit!" Though he sounded angry, his face was anything but, close to pouting with a heavy blush on his face, his teeth beginning to bite his lip.
Sukuna laughed as he pulled away slowly, expression serene. He watched the pulse of Megumi's cunt as its gape attempted to decrease slowly, and watched as the boy began to squirm again. He was probably in something close to heat, even if it wasn't a full one. Sukuna wasn't quite feral yet.
It took a few moments for Megumi to speak up again, licking cooling cum off the edge of his lips. "Give me more. I want your knot, I want to cum again, come here."
Sukuna licked his mouth and chin clean of slick as he slowly lowered Megumi's body. "Your pleasure is mine, my love." It felt like it always had been, and like it always would be.
