  “Sukuna, wait!” Yuuji called. He stumbled out the door, yanking his bag over his shoulder. 

  His twin brother rolled his eyes from half a block away. Sukuna’s voice echoed down the street, “I’m not slowing down for your sorry ass! Catch up or you’re getting ditched.” 

  The morning air was pleasant, a bit on the warm side with a slight breeze. It was a perfect day, the kind of day that Sukuna tended to skip. Yuuji ran after Sukuna. He couldn’t quite wipe the grin off his face, pleased that Sukuna was actually coming after all. 

  “I thought you were cutting class today,” Yuuji said as he finally caught up. “Change your mind?”

  Sukuna scoffed. “Gojo’s gonna be giving a pop quiz today. I’ll be d@mned if I let him use this as a chance to ruin my grade.”

  “Oh f@ck, how did you hear about that?” Yuuji felt himself pale. “I’m definitely going to fail.”

  “You’ll do fine, brat, just remember what we f@ck@ng studied,” Sukuna drawled. 

  He was the only reason Yuuji was passing at all. Sukuna didn’t care about school at all, but he was good at it, far better than Yuuji. Sukuna had perfect grades despite skipping most of his classes, a fact that irritated most of their teachers and left Yuuji in quiet awe. 

  Even with all of Sukuna’s grumbling and complaining, he still explained things to Yuuji in a way that made them make sense. It was one of those little things that reminded Yuuji that his brother didn’t hate him, no matter what he grumbled. 

  Sukuna was always more about gestures than words. He was a man of action, and he was never one to sit idly by and let himself be ruled by the niceties of society. Strong, confident, and brave. Yuuji’s little brother was amazing. When he felt a tickle in his throat, he ignored it, clearing his throat firmly. 

  “You better not be getting sick,” Sukuna said. “I’m not playing nurse if you get laid up in bed. You’re on your own.”

  “I’m not sick,” Yuuji retorted. “I just need some water.” Sukuna rolled his eyes. 

  Whatever Sukuna’s mysterious sources were, they were never wrong. Gojo-sensei’s pop quiz was rough. If not for the warning, Yuuji doubted he’d have been prepared for it. 

  Sukuna walked out with a perfect score, the @ssh@l@. Yuuji passed, just barely. He coughed as they left the classroom. He was still trying to clear his throat when he noticed the dirty look Sukuna threw him. “Don’t you dare infect me with whatever plague you’ve got.”

  “I’m not sick!” Yuuji grumbled. Sukuna was such a b@tch about these things. Still, he felt his chest warm when Sukuna bumped their shoulders together as they walked. 

  It was always like this between them, ever since they were young. Sukuna was always the imperious one, Yuuji the more easily-going twin. But despite the difference in personalities, they were as close as two people could be. Yuuji couldn’t imagine life without his brother. 

  When they were together, the world felt right, like pieces fitting perfectly into place. When he thought about the future, the only thing that seemed certain was Sukuna’s presence at his side. He loved his brother with every fiber of his being. 

  The dreams that plagued his sleep just weren’t important.

  Their schedules were almost identical, and they made it through the day to lunch without too much issue. Their friend Junpei slid into the desk beside them, already opening his lunch. 

  “Man, I hate pop quizzes! I did so badly. How did you do on Gojo-sensei’s test?”

  “Sukuna here got a perfect score,” Yuuji grumbled. “I barely passed.”

  “How do you do it?” Junpei complained. He picked at his food with a sigh. 

  Yuuji coughed softly, clearing his throat. Sukuna glared at him. “It’s not hard,” Sukuna said with a shrug. “Gojo loves trick questions, so when you expect them all to be tricks, it’s easier.” 

  “Hey, Sukuna, are you going anywhere tonight?” Yuuji asked. 

  Sukuna shrugged. “You have your club, right?”

  “It’s going to be a short session tonight, so I’ll be home early,” Yuuji said. “Do you want me to fix something for dinner?” 

  “F@ck yes,” Sukuna said immediately, slamming his hands down. He grinned wide. Yuuji felt warmth bloom in his chest, and he smiled. No, the dreams didn’t matter at all. The real Sukuna was more than enough for Yuuji, and that was that. 

  It was rare to see Yuuji sick. He was healthy and strong, and the few bugs that were strong enough to knock him on his ass would invariably hit Sukuna, too. They were as close as brothers could possibly be, after all. 

  The difference this time was clear: Sukuna wasn’t sick, but Yuuji definitely was. His cough worsened over the following days, a persistent tickle in his throat that refused to fade. He chugged water, and it helped the feeling a bit, but it didn’t eliminate it entirely. Still, it wasn’t bothersome enough to get it looked at. It wasn’t more than a bit of a cough, and Yuuji felt silly to worry about it. 

  A week had already passed since it began. They were running laps around the building, and his cough hadn’t bothered him much at all today. It was a pleasant change. 

  The sun beat down on them, but not even the heat of the day could sour Yuuji’s good mood. He looked over at his twin brother, breathing hard and heavy through his wide grin. 

  Sweat dewed on Sukuna’s skin, casting his face and gleaming muscles in a glittering kind of light that left Yuuji staring. They were identical in every way. Yuuji knew it, told himself that every morning. Yet somehow, the way Sukuna carried himself never failed to draw Yuuji in. There was a lazy, almost deadly grace to every loping stride, like a tiger coiled and ready to strike. 

  Yuuji was more superficially popular by merit of his personality, but he wasn’t deaf to the comments from girls around the school. Yuuji was more approachable,, but something about Sukuna just looked more dangerous, more thrilling. It made shivers race down Yuuji’s spine. 

  “What are you staring at?” Sukuna drawled. Yuuji stumbled over his own feet. 

  The tickle was back in his throat, and this time, it was worse than before. Yuuji broke away from the group to hack and cough, struggling to breathe. The air felt sharp, almost. He wheezed and clutched his chest, sucking in ragged breaths between coughing fits. 

  Sukuna kept running without even a glance back, as if he thought Yuuji was just being dramatic. When he saw Yuuji really wasn’t following, he circled back. “What’s wrong with you?”

  “Just need… a moment,” Yuuji managed to wheeze between coughs. He covered his mouth, trying to hold back the cough. It broke through, spattering his hand with blood and something solid. 

  Yuuji blinked at his hand. The strange, solid thing was tiny, only a few millimeters wide and a few centimeters long. It was just as red as the blood, twisted and wet. He poked it with his finger. It was velvety soft, like a flower petal. He impulsively hid it from Sukuna. 

  “Sh@t, you’re coughing up blood now?” Sukuna said. “What the hell did you catch?”

  “I’m fine, I swear!” Yuuji said hoarsely. He jogged over to the water fountain. After coughing up whatever it was he now held in his hand, his breathing had evened out immensely. He took long, deep breaths, sipping water to soothe his ragged throat. Alone, he looked more closely at what he’d coughed up. 

  It was spindly and delicate, fragile as wet paper. When Yuuji rinsed the blood from his hand, he dropped the thing by mistake and watched it swirl down the drain. 

  It was weird, but it was nothing, Yuuji assumed. He rejoined the group, his breath a little more ragged, but no worse for wear. Sukuna eyed him curiously. He frowned but said nothing. 

  That was the end of it, Yuuji thought. At home, he cooked and cleaned, then studied with Sukuna. The coughing fit was almost a forgotten memory. He cleared his throat, working through the homework that had been assigned. Beside him, Sukuna had already finished. He watched Yuuji’s pencil move across the page, eyes narrow. After a beat, he shifted, digging out his phone and starting to play a game. 

  Their shoulders bumped. It was an accident more than anything else, but it made Yuuji’s cheeks warm all the same. Something about the quiet intimacy of them sitting beside each other always had an unnatural effect on him. He could feel his twin’s warmth through their clothes, feel his presence beside him almost as if he had a sixth sense for it. 

  Sukuna groaned. “I’m going to stretch my legs and go to the vending machine across the street. Think you can manage to not choke on your own spit while I’m gone?”

  Yuuji groaned. “Oh, come on, it was one coughing fit. I’m fine. Get me one, too.”

  “Get your own,” Sukuna retorted. He vanished out the door. Yuuji returned to his homework, still thinking about how it felt to have Sukuna so close. 

  The dreams were getting worse, more frequent and vivid. Mornings were awkward when he had to clean his sleep pants without letting his twin see. But other than that, other than the deep seated longing that festered in Yuuji’s chest, this was fine. He could live like this. 

  He could just avoid thinking about a future where everything would change, when he would likely lose Sukuna to whatever the future held for them both. One day, they would both have careers that took them away from one another. They would be too busy with friends and work and life to spend their days together like this. 

  Yuuji felt the tickle again. He tried to swallow it back, but the feeling crept up more intensely than before. He gagged on it, sputtering and having to turn away from his assignment. It hurt. God, why did coughing hurt so much? It dragged along his throat, painful and sharp.

  Yuuji grabbed a tissue for his mouth, hacking into it. He spat up blood and something solid once again. Amidst the crimson soaking into the tissue, there was a brilliantly red, slightly waxy red petal once again, spindly and delicate. It was clearly a flower petal, but not one that Yuuji was overly familiar with. He couldn’t think of any flower with petals as long and thin and red as this. 

  He heard the front door open, and hastily he wadded the petal inside of the tissue and wiped his mouth clean. He tossed both into the trash. 

  He cleared his throat as Sukuna dropped into the chair beside him, not looking as Yuuji as he set down not one but two cans. Yuuji smiled. “Thank you, Sukuna,” he said warmly. 

  Sukuna scoffed. “This is a reward if you can finish this d@mn assignment within my lifetime. Hurry up.”

  Yuuji laughed, but the warmth in his chest soothed the ragged ache in his throat. He hurried to get back to work, pushing the tissue and the petal from his mind. 

  It wasn’t spoken about often. Hanahaki disease was like any other weird, infrequent, and devastating disease to plague humanity— a novelty, but one spoken of in hushed tones. Some treated it like cancer, and it made sense. 

  When a person’s love was too intense, unrequited and desperately longing, it was usually just that, just an emotional debilitation that, while painful, never grew to more. People the world over suffered from such things, and many of them never faced anything more than that. It was in the rare fraction of a percent of sufferers that something more developed, something that was even worse than the emotional suffering of lovelorn feelings. 

  It was said that in cases of Hanahaki, flowers took root somewhere between the heart and the lungs, growing there and feeding off the unrequited feelings. It was a disease of quick progression, killing its victims in weeks or months, but never years. Few managed to last that long without succ@mbing to the roots clutching at their heart, the flowers tearing into their lungs. 

  Yuuji knew this. When he coughed a third petal up the following morning, it was all but certain that his days were now numbered. A quick web search was enough to confirm his worst fears. The delicate red petal was from a spider lily, a lovely, spindly thing with a dark reputation for death. 

  Based on the frequency he was already coughing up petals, the prognosis wasn’t good. This many petals in only two days meant a particularly violent and aggressive strain of Hanahaki. Yuuji would be lucky to see the end of the school year. 

  He told no one, not even Sukuna. Though they told each other everything, this was one secret that Yuuji could never share. Yuuji was the older one, if only by minutes. It was his job to protect Sukuna. He would protect him from this, even in death. 

  The dreams were Yuuji’s solace, as much as they were the source of his guilt. In the night, visions of writhing bodies and angry kisses flooded his mind. He dreamed of his hair being pulled, his hands pinned to the bed, his body f@ck@d and filled and stroked until they both found their release. 

  During the day, he struggled to breathe, prone to coughing fits. Only at night did he rest easy, only to be plagued by the sweetest torture of his wet dreams. Yuuji tried to hide it. He desperately wrapped the petals in his bloodstained tissues, and he buried each one in the trash can so Sukuna could never see. 

  If one of them had to suffer, let Yuuji bear the burden alone. He couldn’t allow Sukuna to know the weight of his sins. 

  “Brat. Hey, look at me,” Sukuna snapped. Yuuji weakly sat up, struggling to suck down a shaky breath through the constriction around his lungs. It was getting harder to breathe by the day. 

  “Sukuna!” Yuuji said brightly, before dissolving into a coughing fit. 

  “You 
  
    never
  
   miss school, ever. So imagine my surprise when I walk into class and you’re not there? What the f@ck is wrong with you? I’m about to drag your ass to the hospital, so you’d better start talking!”

  “No!” Yuuji croaked. There was nothing the hospital could do. His options were limited to alternatives that were each more awful than the last. 

  Yuuji’s smile fell away as Sukuna continued to stare down at him. He had really thought that Sukuna would skip today. He certainly hadn’t expected to be caught. All too quickly, another cough stole his attention. 

  Sukuna’s expression darkened. “Tell me the truth. You know what’s wrong with you, don’t you?”

  “It’s just a cough-” 

  “B@llsh@t!” Sukuna roared. “I’ve seen the flower petals. You weren’t even going to tell me? Who is it? I’ll kill them, I know that’s one way to fix it.” 

  “No!” Yuuji hissed, as his cough worsened. He bent double, hacking harder than ever before. Tears leaked from the corners of his eyes as his body was wracked by huge, gasping coughs. It felt like knives raking along the inside of his throat. The tickle grew worse and worse, screaming white hot pain through his nerves. 

  When Yuuji opened his eyes, sucking down air, he saw a perfect, complete flower in his hands. The spindly petals were unfolded and open, beautiful and terrible in one. Sukuna sucked in a sharp breath. “F@ck.”

  If Yuuji was coughing up full flowers, he had only a couple days left at the very most. Most likely, he was down to hours. 

  Sukuna screamed in anger, kicking over the coffee table. “Tell me who did this to you. I’ll make them love you back or I’ll kill them!”

  “Calm down!” Yuuji croaked. “You aren’t killing anyone!”

  “Then you’re getting them removed!” Sukuna insisted. He stalked closer, grabbing Yuuji by the arm. “Come on, we’re going to the hospital.”

  Yuuji ripped his arm away. “No. I refuse.” Sukuna knew as well as Yuuji did: removing the flowers would take away his ability to love forever. Yuuji would rather die than lose this feeling, no matter how much pain it caused him. To live a life without ever being able to feel love? It was no life at all. 

  “So what, you’re just going to let yourself die?” Sukuna looked absolutely livid as he stared Yuuji down. 

  Yuuji was quiet for a moment, before he slowly nodded. “I can never tell the person I love my true feelings, and I would rather die than lose my love for them. So yes, I am going to let it kill me. I’m sorry, Sukuna.”

  Sukuna’s eyes burned with fury. His whole body trembled with rage. “You…” he whispered. His eyes shimmered. 

  Yuuji dissolved into another coughing fit. He was growing weaker by the minute. The pain was so terrible, he couldn’t even sleep anymore. Every minute was agony layered on agony. He could feel himself crying. Wordlessly, he held his arms out.

  Sukuna hesitated, but he sank to his knees at Yuuji’s side, holding Yuuji in a tight embrace. “You’re so stupid,” Sukuna whispered, but the venom was almost entirely gone. In its place, there was only the broken sound of pain. “What about me?” 

  “You always were stronger than me,” Yuuji said with a little smile. “Stronger and smarter and better.” He clutched his chest as a spasm of pain wracked his body. “Ah, hurts…”

  Sukuna held his breath, staring at the red flower crumpled inside the tissue. He stood up sharply. “I’ll be back. Don’t die until I return,” he said, turning on his heel. 

  Yuuji watched him leave, feeling his chest ache with longing. Hours of pain passed before Sukuna returned again, slamming the door. A pill bottle rattled in his hand. He opened it, handing Yuuji a small pill. “Take this.”

  “I already took painkillers,” Yuuji grumbled. “None of them help.”

  “This is a different painkiller. It’ll work, unlike the others.” Yuuji squinted, suspicious. Sukuna pressed it into his palm, his eyes intense as they bored into Yuuji’s. “... Please.”

  Yuuji couldn’t even remember the last time Sukuna had said that word. The desperation in his gaze was impossible to ignore. Yuuji curled his fingers weakly around Sukuna’s, taking the tablet. Of course, even in the end, he could never deny Sukuna anything. 

  Sukuna gave him a glass of water, and Yuuji took the pill with a rough swallow. They sat in silence, Sukuna not looking at Yuuji for a very long time. 

  The other painkillers had done very little to soothe the sharp pain of the flowers’ roots digging into his lungs. Whatever Sukuna had given him, it effortlessly took the pain away and left Yuuji drifting in a soft, hazy fugue. The world dissolved away around him in gradual shades, and he was untethered from it all. 

  Yuuji hummed. There was a softness to his own body, a fuzzy euphoria that made it hard to tell where his mind ended and the pain began. It was nice to let go of the agony. 

  “Sukuna,” Yuuji murmured, eyes fluttering. The more it kicked in, the more certain Yuuji was that this was not a normal painkiller. “Mmm, what did you give me?”

  “Stronger stuff,” Sukuna said. “Oxy. Not cheap or easy to find, so be thankful.”

  “Thank you…” Yuuji breathed slowly in and out. He didn’t know what that was, but it couldn’t be that bad compared to heroin or something, surely. The dreamlike state was hard for him to describe, but he enjoyed the feeling all the same. His hand reached out clumsily for Sukuna’s, giving it a squeeze. “It’s nice. Doesn’t hurt so bad, now…”

  Sukuna squeezed his hand back with an angry sigh. “Why won’t you at least tell me who it is? I thought you told me everything. We don’t keep secrets from each other.”

  “You’d be maaaad,” Yuuji replied. He let his head loll around his neck. The shadows on the ceiling looked so strange. He found his attention wandering. “I don’t want you mad… Love you, Sukuna…”

  “Stupid brat,” Sukuna whispered, angry and pleading. “Just tell me who it is. Yuuji, please. Don’t keep this one last thing a secret from me. If you’re just going to die-”

  “I’m really… really glad you’re here… I’m glad I’m not alone. I’m glad I can have you… close…” Yuuji felt his eyes growing heavy. Prolonged pain had left him exhausted. He barely kept them open, catching Sukuna’s expression morph from agony to anger. 

  Sukuna roared angrily. “Damnit, I can’t take this. I can’t watch you die, Yuuji, I can’t! I refuse! I’ll do anything, absolutely anything to save you. Yuuji-nii, please.” His voice cracked. Yuuji felt his cheeks grow wet. 

  He couldn’t say it. He just couldn’t. Even with his dying breath, this was something Sukuna never needed to know. Right? Except things felt hazier now. His mind was more tangled than before, and it was hard to understand himself.

  Nothing felt real anymore. Sukuna begging? Sukuna didn’t beg. He never begged, and he hadn’t called Yuuji ‘Yuuji-nii’ in years. The cottony feeling was almost too much. Yuuji tried to push it back, tried to make sense of it, but the haze was too thick. 

  He clung to Sukuna’s side. The warmth of his twin’s body against his own was like a dream. He pressed his lips to Sukuna’s temple, then his cheek, then buried his face in his neck, holding Sukuna close. The hazy high had Yuuji drifting far, far away. 

  “Sukuna…” Yuuji exhaled. He shut his eyes tight. His body felt so weak. His breath slipped out in a sigh. “I love you, Sukuna.”

  “I love you, too, you idiot,” Sukuna hissed. His eyes gleamed with angry, unshed tears. “We’re all each other has anymore. I have to know who it is you’re willing to die for.” He squeezed Yuuji in a desperate embrace, as though Yuuji were his lifeline to reality. It felt good to be crushed in his arms. 

  Yuuji shook his head, knowing his heart was breaking but struggling to feel anything beyond the artificial euphoria brought by the drugs. The drugged curtain hung heavily over his mind, blurring his thoughts and slurring his words. It felt so good to hold Sukuna close. It felt good to press his lips to Sukuna’s skin, to feel the warmth between them. Even if this was a mistake, even if it was wrong, it felt 
  
    right 
  
  to say. 

  “No, I mean… it’s you,” Yuuji murmured. “I… I love you. More than I should… I’m sorry, Sukuna…” 

  Sukuna was silent. Yuuji drifted away in his thoughts, smiling away the pain. It was impossible to know right from wrong now. It was impossible to deny himself the closeness now that he had it. The hold around his waist squeezed tighter. A startled moan slipped from his lips. 

  Sukuna’s voice was barely a whisper, shocked and simmering with a quiet fury. “You are the most… stupid…” His voice cracked. He suddenly grabbed Yuuji, hefting him up off the couch. The rush of motion left Yuuji dizzy. He threw his arms around Sukuna’s neck, clinging to the warmth, head swirling. 

  Sukuna, by contrast, was unshakable and solid. Broad hands held Yuuji firmly aloft, with one arm supporting his back, the other under his knees. The walls blurred past them. Yuuji suddenly found himself tossed onto a bed. Sukuna’s bed, to be precise. 

  He laid back like a starfish, spreading out and letting his head roll from side to side. The blankets were really soft. Did Sukuna’s sheets always smell this good?  He rubbed his cheek against the comforter. “Sukunaaa,” Yuuji mumbled. “Why are we on your bed?”

  Sukuna threw his shirt on the floor with a glare. “Because I’m not letting you die over some misplaced belief that I don’t care about you. I’m curing your hanahaki whether you like it or not.” Sukuna grabbed Yuuji by the hips and yanked his pants off, pulling them cleanly free from his body. The air was cool against his suddenly naked legs. 

  Yuuji gently kicked his feet once they were free, luxuriating in the feeling of air passing over his skin. The bed dipped sharply, and suddenly Sukuna was looming over him. 

  Yuuji looked up, falling into the reddish golden color of his twin’s eyes. Sukuna’s expression hardened with resolve. “I’m going to save you, you stupid idiot,” he whispered angrily. A hand cradled Yuuji’s cheek softly. The touch sent sparks through him, lighting Yuuji’s nerves like wildfire. He couldn’t help but moan and lean into it. 

  Everything felt so intense, so overwhelmingly pleasurable. His mind was scattered. There was only warmth and bliss and desire bubbling inside himself. “Feels good…” he breathed. 

  “Yeah?” Sukuna whispered. His breath was hot against Yuuji’s skin. “I’m so mad at you. Idiot. You’re such an idiot, thinking I don’t feel the same. Thinking you could keep this a secret from me.”

  The words blurred together, and Yuuji hummed as he felt lips brush his own. His eyes fluttered. Sukuna looked so beautiful like this, devastating in his divine fury and incandescent in the sheer force of his love. Yuuri touched Sukuna’s cheek. The skin was so smooth and soft. 

  The kiss deepened. Yuuji had never felt anything like it before. Drugged and hazy, his heart skipped a beat as he felt his twin’s mouth clumsily mold to his. He eagerly kissed back. How many dreams of his had started like this? It didn’t feel real. Maybe it was another of Yuuji’s wet dreams, and he’d wake in the morning to find he’d c@m in his underwear yet again. 

  When he felt Sukuna’s tongue trace the seam of his lips, he gladly let them part. The taste was metallic like blood. The softness turned harder, the kiss fiercer. Yuuji whined breathlessly. The glut of sensation was already too much, and it was barely more than a kiss. 

  What was it that Sukuna had given him? A shiver ran down his spine, and Yuuji gasped for air, head thrown back with a cry. Sukuna’s hand had crept over his thigh, and the barest touch had been enough to make Yuuji’s c@ck stir inside the confines of his tight underwear. 

  This was always the part of Yuuji’s dreams where Sukuna’s hand slid up, roughly palming the insides of his thighs and forcing his legs apart. This Sukuna was similar, though he grabbed Yuuji by the knees instead. He wrenched Yuuji back on himself, ass up and knees pressing into the sheets on either side of his head. 

  The stretch was almost too much. Yuuji groaned. Sukuna yanked on his underwear, tugging it free from Yuuji’s hips. He let Yuuji fall back onto the bed. Yuuji’s c@ck, now free, was definitely beginning to get hard. It bobbed in the air, flushed and still stiffening even as Sukuna took it in hand. 

  Yuuji made a pathetic sound. Even just the warmth of Sukuna’s hand was almost enough to make him c@m. He sobbed as his c@ck was swiftly stroked to full hardness, the sheer amount of pleasure overwhelming his mind and senses. It was different from when he jerked himself off, more intense. 

  The painkiller didn’t just ease his pain and destroy his inhibitions, it dialed up his sensitivity as well. Yuuji fisted the sheets, crying out as Sukuna stroked him faster. “F@ck, you’re gorgeous,” Sukuna groaned. A hand shoved Yuuji’s shirt up, fondling at his chest. 

  Sukuna pinched a nipple and Yuuji yelped, though the ache quickly receded into a heavy, sublime kind of bliss. The sensations of pain and pleasure melted into a gauzy, rippling feeling that thrummed up and down his spine. 

  Yuuji’s hands flew to grab at Sukuna’s shoulders, trying to steady himself. The rush was almost more than he could take. “Sukuna— nghh, it feels— so much, ah!” His head fell back as Sukuna twisted his wrist. The steady friction was incredibly distracting. He was lost in Sukuna’s rhythmic pace, letting it carry him away. “Sukuna… more… please,” he whimpered. 

  Sukuna’s nails were painted black, and Yuuji could see the light catching on them as the hand continued to stroke his c@ck. Sukuna exhaled, his breath shaky. He paused, looking at Yuuji’s face. “Is that good?” Sukuna breathed. 

  Yuuji looked up through teary eyes. “Good… feels so good.” He spread his legs apart, aching for more. A small cough bubbled up from his chest. 

  Sukuna swore audibly. “F@ck, hold on,” he said. He shuffled around. There was more cussing as Sukuna leaned over to his bedside table, digging for something. Yuuji heard the sound of something being uncapped. 

  Slick sounds soon followed, along with low grunts. Yuuji’s glazed eyes followed the length of Sukuna’s body, all the way down to where Sukuna’s shiny, wet hand fisted his c@ck. Yuuji groaned and clung tighter. 

  “I need— I need it,” Yuuji panted. 

  “I know you do,” Sukuna retorted, dipping his head. He groaned long and low, getting more lube on his fingers. “Deep breath, relax for me.”

  Yuuji’s eyes fluttered as he felt the first touch against his ass. His whole body clamped down, a startled squeak slipping out of him. He held his breath as Sukuna teased the soft skin between his cheeks. 

  “Breathe for me, breathe,” Sukuna chided. Yuuji whined low and unclenched. He relaxed against the steady pressure of Sukuna’s fingers, taking slower, longer breaths until he felt the first push against the rim. Yuuji gasped aloud. Sukuna’s finger was slick and hot, breaching his body and painting his insides with lube. 

  Yuuji had touched himself before, of course. He’d watched p@rn, jerked off, even played with his ass more than once. But never had he felt anything like this.

  Yuuji’s whole body seemed to come alive as Sukuna f@ck@d him with his fingers. The push-pull drag was almost too tight, riding the razor’s edge of pain, but never enough to make his erection waver. Yuuji sobbed as pleasure built inside him.  

  “I’ll fix you,” Sukuna panted. He wasn’t unaffected by the sight. Yuuji watched him lick his lips, staring down at Yuuji like a feast laid out before him. “I’ll make everything okay. I’ll protect you. F@ck, where is it?”

  Yuuji writhed on his fingers. The stretch was perfection, the slight sting enough to make him sing with every thrust. And then Sukuna crooked his fingertips as he pressed in, and Yuuji nearly came right there. 

  “Sukuna!” he sobbed. His whole world was shaken by that feeling, the pleasure lancing through his nerves and making his whole body come alive. 

  Sukuna grinned. “There it is,” he said, breathless. He gave it a few more thrusts that left Yuuji mewling helplessly, howling as the pleasure gathered in his belly. Satisfied, he pulled his fingers out and dried them on Yuuji’s shirt, rucking it up in the same movement. 

  Yuuji’s vision was a bit hazy, though he couldn’t tell if it was pleasure or the rush of the drugs. He felt his brother line up against him. Yuuji held him as Sukuna started to slowly press into the hot, wet, and oh-so-welcoming cavern of Yuuji’s body.

  At first, the pressure and the pain caused sparks of displeasure to build inside him, but quickly, the hazy feeling consumed anything unpleasant. It left only the dreamlike euphoria of pleasure to fill the void. Yuuji sighed happily. “Ah, ah, feels so nice…” 

  His fingers found Sukuna’s hair, combing through the softness. His legs were split apart to leave room for Sukuna within the heat of his body, and he pulled, trying to entice Sukuna closer, deeper. 

  Sukuna twitched his hips, sinking the rest of the way inside with a groan. His lips sought Yuuji’s once more. Their kiss was clumsy and eager, but welcome in the way it grounded Yuuji, serving as a tether for his drifting thoughts. The intensity of every touch, every thrust, was almost more than he could bear. 

  Yuuji sighed happily. This was utter bliss. Never even in his wildest dreams could he have ever imagined a feeling of fullness like this, the intrinsic completeness that came from his younger brother’s c@ck inside him. 

  “F@ck… Yuuji,” Sukuna panted. His head dipped, forehead against Yuuji’s, breath hot against his twin’s lips. “You’re so f@ck@ng tight, feels so good. Does it hurt?”

  Yuuji smiled dreamily. There was no pain, only the blissful haze of pleasure. His whole body was lax and loose. Even the intrusive feeling of Sukuna inside him didn’t feel bad, only warm and wonderful. “Sukuuunaaa~” Yuuji sang softly. “Sukuuunaaa, Sukunaaa…”

  “I’m here,” Sukuna growled. He kissed Yuuji hard on the lips and Yuuji melted into it. “F@ck, you’re out of it. Come on, time to get rid of this damn plant.”

  Yuuji hummed, clinging to Sukuna as he felt their hips shift. There was only a moment of emptiness, a feeling of void where Yuuji had quickly grown used to being full. And then, with a swift snap, Sukuna thrust his c@ck in deep. Yuuji gasped. His head whirled, the world moving too fast for him to follow. 

  The thrusts built on themselves, a steady rhythm that pounded steadily and sent Yuuji’s body rocking and jostling in time to Sukuna’s heavy breaths. The sound of slapping skin was almost deafening. It was music to his ears, a symphony of wet lube and breathy gasps and moans. Sukuna grunted, his flushed cheek pressed against Yuuji’s. 

  Their bodies were perfect mirrors of pleasure. Sukuna’s rutting came faster, faster, more disjointed as he lost himself to f@ck@ng Yuuji. And Yuuji, for his part, could barely put into words just how divine it all felt. 

  Sukuna rolled his hips. Every thrust was angled a little differently. He sought something out, and he knew he found it when Yuuji jolted beneath him like he’d been electrocuted. Sukuna grinned, breathless. “Good, let’s make you feel good,” he panted. 

  Yuuji could barely hold on as the sensitive spot inside him was stimulated again and again. Unerring thrusts found his prostate, pounding Yuuji hard enough to leave him sobbing. He babbled words of love that were incoherent even to him. His pleasure crashed through him so intensely. He rode the waves of it, chasing that feeling until a sudden @rg@sm ripped through him.

  Yuuji let out a choked scream. The intensity of it was beyond anything he’d ever felt before. Silent screams eked through his lips for long seconds, his body writhing under the grip of a pleasure so fierce that it threatened to blot out his vision and steal the air from his lungs. Hot, wet cum spattered their stomachs.

  He sobbed Sukuna’s name over and over again, letting it write over every last thought in his mind, every doubt and fear. Sukuna kept thrusting, but his pace shuddered. “Oh f@ck, f@ck, Yuuji, Yuuji,” Sukuna groaned, hissing softly as Yuuji’s body milked him for all it was worth.

  He swore as he came hard, filling Yuuji with a flood of hot spend. He rode out their @rg@sms, until the sensitive drag of skin left Yuuji whimpering. 

  Their skin was sweaty, sticking as Sukuna flopped down half on top of him, c@ck still buried in Yuuji’s ass even as it softened. “Can you hear me?” Sukuna panted. He pushed Yuuji’s hair from his face, pressing their foreheads together. 

  Yuuji sobbed as the motion rippled through him. He was so painfully overstimulated that, for a moment, it almost hurt. Just as fast, the dizzying glut of pleasure came back in full force, chasing behind. Sukuna stilled, his c@ck no longer shifting and nudging against hypersensitive nerves. 

  Yuuji sighed. “Love you, Sukuna,” be crooned. 

  Relief painted Sukuna’s face. “I love you, too, okay? Don’t you dare think I don’t. Because I do, you idiot. 
  
    F@ck…
  
  ”

  Yuuji drifted through a blur of euphoria. It was hard to make sense of anything that wasn’t his twin’s body against his. The quiet that came after the rush seemed to ring in the air.

  His stomach turned. “Ughh,” Yuuji groaned. 

  Sukuna, absently stroking Yuuji’s hair, paused. “What?”

  Yuuji’s stomach gave another protest, then a firmer one, a nauseated feeling building in the back of his throat. For all the good feelings he’d felt earlier, it seemed his body was paying him back in turn. 

  The haziness was still there, but now it made the discomfort feel more intense as well. “I feel sick,” Yuuji whined. 

  “Don’t you dare puke in my bed,” Sukuna warned. 

  Yuuji groaned. The dizziness stopped feeling good and now it was incredibly unpleasant. The rush of the world was more sickening.  The painkiller still did its job, but the side effects were insufferable. 

  “I feel awful,” Yuuji gasped. He clutched his stomach in misery. 

  Sukuna tsked. “That can happen sometimes. More importantly, did it work? Are you cured?”

  Yuuji let his head fall back, trying to hold in his discomfort by biting his tongue. The tightness in his chest seemed to have lessened. “I think I need a kiss,” Yuuji said in a small voice. 

  Sukuna let out a half startled chuckle. “So needy. Good thing I’m here to help.” Yuuji melted into a slower kiss than the ones they shared before. It was lazier, less hurried. 

  Sukuna’s c@ck slipped free from Yuuji’s body. He groaned as it did, the mess slowly leaking out. He didn’t bother to move. Neither did Sukuna. The quiet between them stretched on, broken only by Yuuji’s pitiful whines and groans of pain. 

  What had before been a blissful fugue now became gastrointestinal torment, made worse by the intensity of every one of the feelings rushing through him. He clung to Sukuna, shaking from the agony. Sukuna shushed his whimpers, petting his hair and holding him close. 

  “Of course you have the bad side effects, too,” Sukuna grumbled, but there was no bite. “Just sleep it off. I’ll be here when you wake, okay?”

  “Promise?” Yuuji whispered.

  Sukuna sighed. He kissed Yuuji’s forehead, letting his lips linger. “I promise.” 

  It took hours, but Yuuji slept off the worst of it. In his sleep, the roots and vines around his lungs began to wither. The stranglehold the hanahaki had on his heart started to relax. Sukuna’s arms around him seemed to almost hasten his recovery. 

  Yuuji woke to find Sukuna scrolling on his phone. His arms were still wrapped warmly around Yuuji, content to hold him close in the darkness. Yuuji felt dazed when he first stirred. He was content to lie there, unmoving and breathing slowly, letting his world stop shifting sickeningly. 

  “Good, you’re alive,” Sukuna said, but the relief was evident on his face.  

  Yuuji groaned. “Bleh, I feel awful still.” His voice was ruined. His throat hurt horribly, and his stomach was still tied in knots. He felt like he might puke. 

  Sukuna held up a gnarled-looking branch, the roots withered away and the length of it dotted with deceptively beautiful red flowers. Spider lilies. Yuuji coughed, but there was no tickle this time to cause it, only the angry burn in his throat. 

  “You coughed this up while you were half asleep. I had to yank it out of your throat before you choked to death on it. You’re welcome, by the way.”

  “Thank you,” Yuuji rasped. He sucked in a sudden breath, his eyes going wide. He had broken his own promise. He hadn’t been able to protect Sukuna from his dark secret in the end. 

  Yuuji had hoped to take it to the grave with him, let it be buried with his shame, but in the end, he was too weak. He had broken down in the worst of ways. His breath shuddered out in a rush. “Oh god, we— you and I— I’m so sorry, Sukuna, I never wanted you to have to—”

  “If it wasn’t you, it would have probably been me,” Sukuna said, looking away. Yuuji fell silent. “Don’t look at me like that,” Sukuna scoffed. 

  Yuuji rubbed his face, fighting back another wave of nausea. The fuzziness was almost gone after sleeping for who knows how long, but the queasy feeling was lingering in a bad way. “I’m never taking one of those again.”

  “You seemed to enjoy it while it lasted,” Sukuna said smugly. “I recall you screaming my name—”

  Yuuji leapt up, covering Sukuna’s mouth with a yelp. “That was— I mean, you were—” He broke off, remembering the intensity of Sukuna’s gaze, the devotion with which he f@ck@d his own brother— Yuuji slowly pulled his hand away, stunned into silence. 

  “I thought you didn’t keep secrets from me,” Sukuna commented lightly.

  Yuuji flushed and looked away. “What would you have done? I didn’t expect you to be so… receptive. Let alone eager to do what… we did...”

  “Because you wouldn’t f@ck@ng talk to me. When did it start for you?”

  Yuuji cleared his throat. “A few months ago, maybe. You had gotten out of the shower in just a towel, and I just… it felt like I couldn’t breathe when I looked at you. I didn’t want to admit it to myself. Pretended it was just the same feelings I always had. But then I started dreaming of it, and it only got worse. You?”

  “Three years ago,” Sukuna said. “Caught you jerking off. I wanted to f@ck you into the bed, but Gramps was still kicking back then, and I didn’t trust you to keep your mouth shut. By the time he died, there wasn’t a good moment.”

  So long. So many days and months and years that could have been different. Yuuji closed his eyes. “Is this wrong?” he breathed. 

  “Does it matter?” Sukuna replied. “You’re the one who was literally dying to get laid. I’m not planning on letting anyone else f@ck you like that, so you better get used to me.”

  Yuuji huffed out a small laugh. He curled against Sukuna’s chest, closing his eyes. “Good, I don’t want to share you either.” 

  The quiet between them dragged on, but the silence wasn’t uncomfortable. Sukuna had always been the one Yuuji trusted most in the world. Sukuna had always been his other half. Being together like this now, it didn’t feel strange or wrong. It felt right. 

  It felt perfect.'
