The first time it happened, Nanami Kento dismissed it as a fluke.

After all, he and Gojo Satoru had just finished up a grueling multi-day mission together. Any time he was forced to spend an extended period in Gojo’s presence, his mind was left rundown from the constant chatter and foolishness. It was perfectly within reason that his thoughts were full of Gojo then.

It usually took a few days for his head to clear. Nanami was, admittedly, still perturbed by the nature of this particular dream, but sometimes the body coped in odd ways after an ordeal.

And then he dreamt about Gojo again. Even more vividly this time. 

So vividly, in fact, that the first thing he did upon waking was wash his soiled underwear. He was a grown man. If he didn’t live alone, he didn’t think he could deal with the mortification of coming from a wet dream at his age. 

As he scrubbed at the stains, he tried to blink away the feeling of lingering heat. He could still see… everything as if it had been happening only moments ago. 

It was fine. 

He had the whole day to himself. Tomorrow he would return to work. Surely by then, whatever was wrong with his body and mind would settle down. 

Two nights spent dreaming about Gojo fucking him senseless was two nights too many.

Nanami still found himself restless though as he watched the clock tick down toward bedtime. He had cooked himself a light lunch and dinner, not wanting food to aggravate him in his sleep. Perhaps he had eaten too much meat the last few days? Bread? Diet had a very strong influence on rest and health after all. 

He had then lounged in his bath for a good part of the evening, using essential oils and bath salts aimed at relaxation. It was difficult to keep himself awake and as he felt himself drifting, he finally climbed out of the warm water and drained it. 

Of course, he had refrained from dozing off all day as well to ensure nothing could get in the way of a good night’s sleep. 

The day had been spent in optimal preparation for a fitful slumber.

After toweling off, he dressed in his softest pajamas, put on his reading glasses, and tucked himself into bed with a book. It was one he had read many times before. A comforting novel that he used when too anxious to sleep right away. With how relaxed he felt though, it wasn’t necessary. 

Still. 

Nanami nodded off no more than ten minutes later and shut off his lights just before succumbing to sleep.

That night was, without a doubt, the most realistic, mind-numbing sex dream he had ever experienced. 

The first night had felt foggy and muted. The second night had been clear enough for him to see the flush on Gojo’s pale skin. 

The third night was cinematic torture.

Nanami couldn’t speak but he could feel and hear and touch. The slap of Gojo’s hips against his bare ass was impossible to ignore. He was sprawled out on a soft bed, legs spread wide and resting over Gojo’s thighs. 

The view he had was unbelievable. Every sculpted muscle in Gojo’s abdomen flexed when he thrust and when he leaned forward, the heat radiating from his body was palpable. He grinned in that boyish way Nanami found equal parts irritating and charming, and then leaned down to mouth at his neck. 

Nanami’s body jolted at the scrape of teeth but soon found himself more overwhelmed by his legs being hiked up higher and Gojo’s heavy cock ramming even deeper inside of him. He heard himself gasp but didn’t recognize it as his own voice. It was too breathless. Too high. 

“Feels good there, huh?” Gojo murmured against his ear. 

Nanami flinched back, the voice too real and heavy with lust. 

Strong arms caged him in, forcing his body to bend even more to accommodate the angle. Gojo snapped his hips forward faster. Nanami’s vision went white for a moment as pleasure erupted deep in his gut. That voice he didn’t recognize was practically screaming now. 

Gojo snickered in his ear, whispering so much filth that the words just became white noise in the blinding pleasure. 

Nanami’s gaze dropped to the place they were connected and in the throes of an orgasm, he finally realized what was wrong. 

Those aren’t my legs.

He jerked awake. 

His body was covered in sweat and his underwear was sticky with come. Staggering to his feet, he fumbled into the bathroom and ripped the collar of his shirt back. 

There were bite marks littered across his neck and shoulders. Peeling all of his sweat slicked clothes off hastily, he inspected himself in the mirror with dawning horror. 

More marks had appeared. 

Bruises in the shape of fingers on his thighs and hips. Purpling hickeys down his ribs. Teeth marks around his nipples. With some trepidation, he reached back between his ass cheeks and grimaced at the feeling of a swollen rim and the impossible remnants of lube. His ass was very much well stretched and if he wasn’t sure of the power of curses, he might’ve assumed someone had taken advantage of him in his sleep last night. 

In a way, that remains true.

Nanami supposed it wasn’t the most pressing matter but he was infinitely grateful that Gojo hadn’t come inside this stranger. Whoever it was. He had no desire to spend his morning shower crouched over trying to clean semen out of his ass. 

Particularly when he hadn’t asked for it. 

With a bit too much force, he twisted the knob of his shower and set it to the hottest temperature. 

It was a bit early to call but knowing Gojo, he was wide awake and probably already doing something or other. Nanami had learned shortly after returning to sorcery that Gojo Satoru rarely slept. If it wasn’t dealing with clan politics, it was curse killing. If it was neither of those, it was lesson planning or grading papers. 

And after this weekend, he also learned that Gojo spent his evenings in other ways as well.

“Nanamin?! A morning wake up call? What a treat!” Gojo’s peppy voice boomed through the phone and Nanami winced. 

“Gojo-san, will you be on campus today?” He sighed, rubbing the bridge of his nose. 

“Are you eager to see me?” he laughed. “Well, can’t say I blame you! Our last mission was so much fun, huh? You miss me already? Let’s go somewhere warmer next time though. You like the beach, right? I bet there’s a cursed island or something we can — ”

“Please focus, Gojo-san. Are you available in person today?” Nanami cut him off. 

An obnoxious whine through the speaker had Nanami pulling the phone away from his ear. “Mm…I wish I was now that you’re begging! I’m hunting a special grade that popped up in Kanazawa. Looks like it might take a couple days to finish up here.”

Nanami couldn’t decide if this was a blessing or not. If Gojo was on a mission, surely he wouldn’t be finding strangers to fuck, would he? Or maybe he always did this on solo missions. A way to relieve stress, perhaps? 

All of that could be irrelevant though, if that wasn’t how the curse worked. Nanami had no proof and certainly didn’t want to throw caution to the wind on the matter of proving or disproving his theory. Regardless, he knew Gojo was related to this curse and if he could just get Gojo to stop doing anything at all whatsoever, he could be assured that his dreams would be restful.  

And his body would no longer bear such humiliating marks.

There was no feasible way to forbid Gojo from sleeping with people. Nanami didn’t think he could even find the appropriate phrasing for that request. This matter also wasn’t something they could settle over the phone. Not only was it a situation filled with unknowns, it was also mortifying enough that Nanami would rather they discuss this privately and not over a traceable line. 

“A few days. Are you sure?” Nanami murmured. 

“The second I find it, it’s over, y’know?” Gojo replied, as if the matter of a special grade curse was nothing at all. 

For him, that could be true. Was often very true. 

Nanami nodded to himself. “Alright. Please proceed with restraint.”

“Against a curse?”

He opened his mouth to clarify and then thought better of it. “Nevermind. I’ll see you in a few days.”

“We can still talk before then, Nanamin! Don’t be so cold!”

He ended the call.

There were just a few more sleepless nights at worst. Nanami would handle it and in the meantime, he would furiously search for information on the curse attempting to ruin his life. 

***

The first night away was silent. 

Nanami was surprised but grateful nonetheless. If his theory was correct, then maybe Gojo did end up being too busy to find a convenient fling?  He had very little faith that Gojo was working diligently but it seemed he was wrong. Was he perhaps rushing to get back sooner? That would be excellent. 

The urgency of Nanami’s request was being taken seriously.

Wonderful.

And then the next night came and he rescinded any kind thoughts he had about Gojo. 

When Nanami drifted to sleep, he woke to visions of a heavy cock pushing against his lips. They were outside in the dark of night. Perhaps the alleyway of a bar? It was hard to tell in the dim setting but there was enough light from an emergency exit sign to case Gojo in shades of neon. 

His eyemask was firmly in place, grin wide and sharp as he fed this stranger his dick. There was something intimidating about Gojo from this angle. More than usual. Far from being a small man, Gojo didn’t need a height advantage in any situation and right now, he looked and felt absolutely gargantuan. 

Nanami immediately choked as the head of Gojo’s cock brushed the back of his throat. Veins pulsed against his tongue at the sudden constriction of his mouth and Gojo’s lips parted in pleasure. 

“Can’t take all night,” Gojo snickered, rolling his hips forward and back while sinking long fingers into Nanami’s hair. Someone’s hair. “Wanna give up?”

He moaned around the shaft and started to bob his head in earnest. Gojo guided him, setting a pace and rhythm that soon had his throat loosening up and his jaw hanging slack. The girth of his cock was nothing to scoff at and it only seemed to grow thicker with each pass. 

Nanami’s eyes rolled back at the mounting pressure and strain. He curled a hand around the base of Gojo’s cock, stroking what he could no longer handle sucking. His throat felt raw already, saliva pooling and slipping from his mouth in a desperate effort to make the glide easier. Nanami couldn’t tell if he was disgusted or aroused by the wet noises anymore, spittle clinging to his tingling lips. 

Abruptly, Gojo slid free and Nanami fell forward, coughing. 

The emptiness was profound. A blessing. A failure. 

Nanami wasn’t sure. 

Gojo tore open a condom and rolled it over his glistening cock. His field of vision suddenly shifted and he was given an eyeful of brick wall. Thin, carefully manicured fingers came into view and Nanami’s body chilled. They braced themselves against the wall while a cool breeze suddenly wafted between his legs.

Wait.

Panic rose up in Nanami as he felt a thin string of fabric peel away from his crotch. 

Is this a woman? 

How was this going to work? He didn’t have—

Pleasure surged straight to his prostate. Nanami’s vision blurred. The stretch wasn’t the same. Not exactly. The experience was murkier than usual. Foreign to his incompatible body. But there was nothing vague about the way his nerves were being stimulated. 

He felt himself coming within seconds. And then again.

And again.  

And again —

His eyes burst open. 

Whipping the blanket back, he prepared to see a sticky mess but there was nothing. His skin and clothing were drenched in sweat though. Nanami gingerly peeled his pants and underwear back, finding a bit of wetness but nothing like semen. 

His dick was more sensitive than usual. Nearly tender to the touch. It felt like it had been very thoroughly used up last night and yet there was zero evidence. Nanami shut his eyes against the inevitable. 

At least a dozen dry orgasms was easier to deal with than a come-covered cock and gaping asshole. 

Nanami couldn’t even sleep away this nightmare. Closing his eyes already made him wary of what would happen if he drifted off. 

Staying awake is safer.  

When he fell asleep the next night, it was reluctantly and only after hours of desperately trying to induce insomnia. Nothing worked. No amount of caffeine, sugar, or energy drinks could fight off the power of the curse. 

Nanami had spent quite a bit of time looking into it, but found very little in the way of breaking a lust curse. There were too many ways and too many factors. Was it a curse made from malice? A curse made from romantic arousal? Was it to charm or to terrify? 

Without these answers, they could only fumble around for a method to break it. What he needed more than anything right now though was for Gojo to stop having sex. And also to return to Tokyo immediately. 

That night, Nanami was spared another sexual encounter. 

But this one was, arguably, worse. 

Nanami didn’t recognize the bar. It was a nice place with a view of a city skyline. Or at least, that’s all he could make sense of before Gojo filled his vision, blue eyes sparkling in dim light. He was dressed casually which told Nanami that he was certainly off duty. 

Why didn’t he come directly back to Tokyo?  

Irritation clouded his thoughts briefly but the curse was demanding and he was soon forced to redirect his attention to whatever it was Gojo had planned with this stranger.

“Where are you from?” Gojo asked, white lashes bowing. 

Nanami wondered if he could take over this stranger’s body just to roll his eyes. It seemed the sensations were a one-way road though and he was made to listen to the muffled responses and Gojo’s half-hearted replies. It was clear to Nanami that the only thing on his mind was getting his dick wet but this poor foolish fling had no idea.

Or perhaps Nanami just didn’t understand these types of encounters. 

The half-heartedness seemed to go both ways because not even ten minutes later, he was being led toward the back of the bar by Gojo. 

Immediately, he was crowded into a dark corner, chin tipped up, and mouth finding another warm mouth. Just like with everything else, Gojo excelled at kissing too. Nanami hadn’t had time in previous encounters to think critically about whether or not the sloppy kisses they had exchanged were noteworthy.

Right now, without the distraction of his monstrous dick inside of him, Nanami—the stranger —was melting. Large hands curled around his waist as a tongue slipped past his lips. It was wet and hot and each time Gojo nipped at his bottom lip, heat stirred low in his belly. 

“Mm, you wanna get outta here?” the stranger panted.

“Sorry, can’t stay out,” Gojo murmured. 

Nanami scoffed. He knew this man well by now. Gojo was a beast. How dare he pretend to be anything else. By the looks of it, the night was already in full swing. Was he going to now go and kill a few curses while continuing to ignore Nanami’s call for help?

“You got me all worked up for nothing?” the stranger complained, half-playful, half-serious.

“‘m sure you can find someone to help you out.” He grinned, smoothing his thumbs down their hips. “Just had to get this outta my system before I get going.”

“Oh? We can work the rest outta your system too—”

Gojo laughed brightly, interrupting that train of thought. “I’m sure! But sometimes…,” he trailed off, expression growing oddly fond. “Well, y’know how it is when you haven’t seen your, uh, pet or something? In a long time? And you just wanna shower it with kisses because it told you it misses you?”

The stranger laughed, confusion making their voice shake. “I guess that’s true. My pets don’t usually talk.”

Nanami jolted awake to the sound of banging at his door. 

He had fallen asleep on the couch, tangled in blankets. The coffee table was littered with various drinks and food from his attempts at insomnia. A drama series was playing on the television as well, cued up to auto-play into infinity. Even with the volume as loud as it was, Nanami had managed to drift off.

The curse was to be taken quite seriously.

Staggering to the door, his visitor was banging on it even louder now. Nanami scowled, checking the clock on the wall as he finally unlocked the door. 11:46 p.m.

“I’m back!” Gojo sang, inviting himself into the apartment with a souvenir bag dangling from his wrist. 

Nanami subconsciously brushed a hand over his swollen bottom lip and frowned. “When did you return?” he grunted, voice still rough from sleep. He eyed the familiar casual attire from his dream. 

That was certainly some evidence that his theory wasn’t far from the truth. There appeared to be a bit of a delay though. A time lag of experiencing the wet dreams and the reality of when the act occurred. Minutes? Hours? An indeterminate amount of time that was determined by…something? 

His head throbbed. 

“Well, a little bit ago, but you know how things just happen,” Gojo shrugged. “Anyway, you must’ve missed me so much! I don’t think you’ve ever missed me this much!” He grinned wide and tossed the souvenir bag on the kitchen table before throwing himself at Nanami.

Being hugged by Gojo was akin to getting slammed into by a brick wall. Nanami couldn’t really say he had ever enjoyed the sensation; however, he was horrified to discover that he didn’t mind this time. 

It was disconcerting how he felt comfortable in Gojo’s arms now. They were familiar. Painfully so. These arms. Those hips. This body. It had embraced him countless times in the last several days, never allowing him rest or reprieve. 

Nanami was, all at once, furious and achingly hard. 

The faint smell of bar smoke and liquor clung to Gojo’s clothes and for once, Nanami took notice of it and understood exactly where it had come from. There’s simply no other explanation.

Shoving Gojo back, Nanami took slow, calming breaths. 

“Huh? What’s wrong?” Gojo suddenly pushed his blindfold up. When did he switch out the sunglasses for them?  

Nanami backed away, scowling under the scrutiny of Six Eyes. “Please stop having sex with others.”

Gojo blinked.

The words played back in Nanami’s head and he sighed. “That wasn’t what I meant. Gojo-san—”

“—that’s a wild way to confess your undying love, Nanamin,” Gojo interrupted, grinning full force and flinging off his blindfold. “Not that I mind! I like your bluntness. It’s—”

“—no, you’ve misunderstood. I—”

Gojo crowded him against the kitchen table, hands caging him in. “No need to be bashful! I know we had a really great time on that last mission. It’s not surprising you finally realized you love—”

“—that mission was a headache and had terrible long term consequences—”

“— of love! I get it—”

“—you do not. It’s a curse—”

“—yeah, some people have called love a curse. It totally makes sense with how overwhelming the feelings are—” 

Nanami slapped a hand over Gojo’s mouth, neck burning and vision bleeding red from frustration. He tried to pry off the hands that had migrated to his waist but found it ineffective when he was trapped like this. 

“Will you be quiet and listen?” Nanami snapped.

Gojo’s long white lashes fluttered and he smiled against Nanami’s palm. Muffled words vibrated against his skin, none of them intelligible. 

Sighing heavily, Nanami kept a hand firmly over Gojo’s mouth as he began to explain. “I believe a lust curse has been cast on either just me or both of us.”

Large blue eyes stared at him, unblinking.

“Do you understand, Gojo-san?” Nanami resisted the urge to shake him—not that shaking him would do much, if anything at all. “This curse causes physical harm and is triggered by sexual activity.”

The words finally seemed to register as Gojo backed off. His hands lingered on the curve of Nanami’s waist, but Six Eyes was scanning him properly now. 

Nanami removed his hand.

Gojo frowned, eyes narrowing. “Yeah. There’s something weird with your cursed energy. It doesn’t look like it’s a high level disruption though.”

“It’s not. It’s an annoyance.”

He tilted his head. “What did you mean by it causes physical harm?”

Nanami opened and then immediately shut his mouth. He had been so focused this entire time on preventing himself from sleeping that he hadn’t considered how to go about this conversation with Gojo. Some part of him had hoped, rather ridiculously, that Gojo could just eviscerate the curse. Perhaps blast him with a strong enough attack that the curse disappeared without needing an explanation.

“Nanami?”

Frowning, Nanami shook his head. 

“Well, if you don’t tell me, I can’t do anything.”

Heat crept up his face and he shoved Gojo back enough to step away. He put some distance between them, loathing how small and cramped his apartment suddenly felt. It was nothing of the sort, of course, but right now, he couldn’t imagine there being enough space to prevent the ensuing humiliation. 

“Nanami—” Gojo choked on his own words as Nanami tugged his sweater over his head. “Wait, wait, I thought we weren’t talking about love anymore—”

“—I’m showing you the damage, fool,” Nanami interrupted, doing his best to ignore the flush that must’ve been obvious on his chest. He tossed the sweater aside and resisted the urge to cover his bruised and bitten skin.

Gojo’s gaze grew heavy. “Who did this? Does the curse have a physical form?”

Nanami pressed a hand to his forehead, words forming between gritted teeth. “ You did.”

“What?”

“The various…partners you’ve had since our mission. I believe any marks you left on them have appeared on my skin.” Nanami refused to meet his gaze. “I had no idea what to make of the visions I’ve had recently. Initially, they could be passed off as dreams but they grew increasingly explicit to the point I couldn’t ignore the signs upon waking.” Nanami waved a hand at the state of his mottled torso. “That’s why I believe the curse has been cast on both of us.”

Gojo was silent.

And the silence stretched.

And stretched.

And kept stretching until—

“Speak, Gojo-san,” Nanami snapped, retrieving his sweater and jerking it back on. 

“You were watching? You saw all of…those times?” Gojo rasped.

“I wasn’t watching,” he retorted, somehow offended at the implication he was a willing voyeur. “I experienced it first—” Nanami cut himself off. 

Gojo raised a brow. “You what?”

“The details aren’t important. What matters is breaking the curse. Do you have any experience with these types of things?” 

After another long pause, Gojo nodded. “Maybe. I need to check the clan archives to make sure but I think I’ve seen something in there about lust monsters.” 

Nodding curtly, Nanami busied himself with tidying up the living room just to have something to do. “Good. We’ll reconvene tomorrow.”

“Are you sure?”

Nanami paused.

Silent footsteps approached him from behind. Warm fingertips trailed along his wrist, far more tentative than earlier. “That you don’t want to keep me around tonight, I mean?” Gojo’s voice dropped, low whisper rushing along the shell of his ear. “Might get tempted if I don’t have someone watching me.”

“Are you incapable of controlling yourself?” Nanami replied, annoyance not quite making it into his tone. 

“Maybe the lust curse has me hornier than usual,” Gojo mused, a hint of something like genuine wariness in his voice. “I don’t usually get back alley blowjobs while on missions…I just didn’t think anything of the urge then.”

Nanami was about to retort that he hardly believed that given what he had witnessed and experienced the last several nights, but then stopped himself. That was petty and unfair. He had no idea what Gojo did on his solo missions. He had no idea if the lust curse truly did influence his libido or not. 

Certainly, Nanami wouldn’t want to be blamed for the state of his body. He hadn’t asked for wild nightly activities. Who was to say Gojo hadn’t been experiencing equally disconcerting circumstances?

Sighing, Nanami smoothed the plush blanket draped over the arm of the couch. “Perhaps it would be best for us to stay together until this matter is resolved. It’s possible the curse will act in ways we cannot comprehend or it may even mutate over time.”

Gojo abruptly squeezed him, tension releasing from the air as he cheered directly into Nanami’s ear. “We can go to the clan archives tomorrow morning then!”

“Gojo-san, you’re too loud.”

“It’s a precious sleepover with Nanamin! It’s cause for celebration!”  

“I haven’t slept well in many days.” He shot Gojo a withering glare. “And I’ll be retiring to bed shortly.”

Gojo pouted, rubbing his face against Nanami’s shoulder. He tightened his arms around his waist. “Let’s at least have a drink! I brought you back some specialty sake from Kanazawa.”

“...one drink.”

One drink became two. 

Then three.

Until the entire bottle was empty and Nanami was warm, fuzzy, and draped across Gojo’s chest. A half-finished glass of sparkling juice rested on the coffee table. Nanami stared at it blearily, wondering why they bothered drinking when it only ever involved one of them getting drunk. 

It was delicious though.

Not that Gojo had any part in determining that. He always just bought what was popular.

Long fingers stroked Nanami’s hair. “Was it good?” Gojo cooed. “You seem sleepy now.”

“I was already tired,” Nanami sighed, pressing his cheek harder against the thick muscle of Gojo’s chest. It was hard and unyielding, but Nanami found comfort in the heat radiating through his shirt. 

They had somehow ended up tangled together on the couch, throw blanket draped over their legs. 

Nanami vaguely noted the hand drifting down his lower back and rucking up his sweater. It didn’t seem particularly invasive. Not from Gojo, at least. I’m accustomed to his touch already.  

He wanted to scoff at the thought. The curse had done more damage to his boundaries than he would’ve liked to admit.

“Nanamin? You still awake?” Gojo asked softly, rubbing his lower back in lazy circles.

He grunted, but could feel his consciousness fading.

Gojo chuckled, the ghost of lips atop his head as his fingers dug ever so slightly into his bare skin. “...glad they’re all mine. Every single one.” 

Nanami was already breathing deeply though, sound asleep for the first time in days.

***

“...Lustful curses have three purposes.”

Nanami kept his arms crossed and his breaths shallow in the dusty storeroom. For a clan of such renown, he had hoped the records were kept in a nicer place, but that was wishful thinking. The drafty annex was on the edge of the Gojo Clan estate. It held only documents and records.

Nothing of import to a thief. Well, unless the thief wanted an extended library of primary reading sources. Nanami supposed that was why it had little maintenance. 

Most curses could be obliterated with enough force.

“One reason is to entice,” Gojo read aloud, far too amused by the situation for Nanami’s liking. “The curse caster inflicts the target with their own desire in hopes of being desired in return.”

“Considering neither of us cast it, that can’t be the reason,” Nanami deadpanned.

“Reason two,” Gojo flipped a page, “the caster desires to inflict sorrow on the target by making them desire everyone but their lover.”

Nanami pursed his lips. That one did seem quite plausible. Although they weren’t lovers, if the curse mistook them as such, then it could be the case. Perhaps Gojo was burying his lust in strangers while his supposed lover, Nanami, was forced to live through the nightmare of infidelity every night.

“Is there anything else written about that one?” Nanami prompted.

Gojo was already flipping ahead though. “Well, it doesn’t sound like it fits our situation, so I doubt it’s helpful to keep reading about it.”

“I can see the merit. There’s the chance—”

“—nah.” Gojo laughed and shook his head. “If anything it’s the opposite.”

“You’ve been sleeping with copious amounts of people.”

“And if you saw any of them, you’d definitely have things to say,” Gojo mused, eyes drifting to him. Even with the blindfold in place, Nanami could feel the weight of his gaze and resisted the desire to squirm. “Trust me. If Nanami is considered my lover in this curse, then I only want my lover.”

Not allowing any time to unpack that, Gojo’s grin grew and he started reading again, “Aha! And here we come to reason three. Finally, a lust curse may be cast with the purpose of…oh.” He expression fell, growing increasingly perturbed the more he read.

Nanami’s body chilled. “What?”

Gojo’s lips thinned.

He flipped another page. And then several more, reading at a much faster rate than earlier. 

Nanami came up beside him, snatching the book from his hands. 

Finally, a lust curse may be cast with the purpose of fertilizing a weak cursed being. Usually, one or more individuals are involved in the energy collection phase. Another individual, the “host,” will receive the energy and also house the underdeveloped curse until it has amassed enough power to either overtake the host body or escape it. Succubi are often a common creature born from these types of lust curses.

Nanami swallowed thickly, nausea roiling in his gut. 

Just like Gojo, Nanami rapidly flipped through the book, seeking out more information on succubi curses. Of course they had both overlooked something like this. It was designed to be weak and unassuming. A parasitic plant that amused itself with bodily fluids and cursed energy.

“I never came inside any of them.”

Nanami’s head jerked up, looking at Gojo who had pulled his blindfold down and was clearly rapidly recalling everything that had happened in the last week. 

“Which, if that’s how the curse works, means I also never came inside of you.”

Nanami pointedly ignored the heat that shot up his neck. “Succubi can collect energy in other ways but the most potent method is semen,” he agreed, clearing his throat. “Do you have any other information on them?”

Gojo turned back to the shelves of documents, digging through them with feverish intent. “I don’t run into low level things like that often. They usually don’t wanna stick around.” He unfurled a roll of parchment, skimming it before returning it to the shelf. 

Nanami flipped to the end of the small book in his hands, trying to focus enough to understand the pages of notes. It felt pointless. The notes were all general. Nothing specific about this curse. All they knew with any certainty was that Gojo had been indulging more and Nanami was experiencing those indulgences in real time.

If this was a succubus incubation curse, then there was only one way to lure the curse out.

“We will feed the curse and grow it.”

Gojo stilled. 

Nanami set the book down, watching his backside carefully. “If what you’ve said is true, the curse has afflicted you with heightened lust. If we accept this book’s conclusions, then there’s a high possibility I am experiencing the backlash of this energy as a ‘host.’ The true curse is clearly hiding and the only way to defeat it is to force it out.”

“Are you asking me to fuck you?” Gojo looked up at him, still crouched on the dusty floor of the archives. 

“It would be the most efficient method,” Nanami responded. “I would rather not endure potential months of the curse recoiling and causing me sleepless nights until it’s satisfied.”

“But we don’t even know if….”

Nanami huffed, impatience and perhaps a touch of embarrassment making his head hurt. “It won’t cause any further harm either. Gojo-san, I am perfectly familiar with you in ways I would rather not say. Eliminating the middleman is all that we would be doing.”

Gojo snorted. “You’re really good at making the idea of me coming in your ass super unsexy.”

“It’s purely professional.”

He barked a laugh, expression torn between genuine amusement and something harder to read. “So what? You’re saying we should just go at it until a curse erupts from your stomach or something?”

Nanami grimaced. “I would hope your eyes could notice and eliminate the threat before that moment; however, should it require such extreme measures, I’m prepared for that outcome.”

Sighing loudly, Gojo stood up and dusted his pants off. “Fine! Purely professional, right?” His blue eyes glowed in the semi-dark, pretty features twisting in something like a smile. “My place or yours, Nanami-kun?”

Despite having plenty of vicarious experience, Nanami couldn’t say he was truly prepared for the feeling of Gojo shoving his tongue into his ass.

He didn’t do this with the others.

Nanami could barely focus on his own thoughts, legs hiked up and hole clenching around Gojo’s intrusive licking. Every time he fluttered around it, he wanted to bury his head in the pillows out of sheer shame. 

He had been wrong.

There was nothing remotely professional about this. 

Gojo ate him out enthusiastically, never slowing or stopping even when Nanami cried out that he was coming. His release cooled on his abdomen and chest, utterly forgotten in favor of Gojo bending and twisting him around for pleasure’s sake. 

“Do you play with yourself a lot, Nanamin? It’s soft and loose down here, y’know,” Gojo noted casually, dipping his fingers inside. 

“It’s because of you,” he spat, full body spasms wracking his frame at the stretch.

“Me? You think of me when you’re—”

“— no! The curse,” he growled, “it spares nothing.”

Gojo’s fingers stuttered. He abruptly pulled them out and dragged Nanami’s hips down until the rim of his ass was kissing the tip of his leaking cock. 

Jolting up, Nanami just barely caught a glimpse of Gojo’s thick shaft disappearing inside of him before pleasure was shooting through his body. He gasped, head tilting back and body falling against the sheets again. He arched up as Gojo bottomed out.

A strong, steadying arm caught him by the waist, holding him up as he was dragged back down on Gojo’s cock. His legs shook against the bedsheets, uselessly sprawled open and inviting Gojo to do as he pleased. Kneeling forward, Gojo lapped up the drying come on Nanami’s chest while rocking lazily inside of him. 

“That means Nanami knows the shape of me already, right?” he breathed, stifling a groan against one pert nipple. “Your body feels like it already loves my dick.”

He tried to find the energy to swear at Gojo, but all that came out was a broken puff of air and a guttural whine. Nanami shut his eyes, trying to breathe through the incredible stretch. It was unbelievably similar to the visions. Uncanny in the way his body knew how accommodate him already. 

Although Nanami would never admit it aloud, Gojo was perfectly correct in his assessment.

His traitorous body loved Gojo’s dick.

He doesn’t need that validation.

A grunt was punched out of Nanami after a particularly rough thrust. The smack of Gojo’s hips against his ass resounded through the bedroom, recalling nights that he hadn’t spent with Gojo. Hazy memories of hotel rooms and dark bars flitted through his mind but just like when he was experiencing those things, he was drawn back to the man above him.

“Fuck,” Gojo panted, dragging sweaty fingers through Nanami’s hair. “Come here.” He fisted Nanami’s hair and yanked him into a brutal kiss. 

If Nanami thought himself mindless before, he had been wrong. This was true bliss. Having Gojo Satoru devour him breathless was incomparable to anything else. 

He wasn’t sure how or when it happened, but they had become a tangled mess together, arms hooked around Gojo’s shoulders and legs tight around his hips. Every thrust had been restricted to a shallow grind as they rolled across the bedsheets. Nanami was no longer certain who was moaning. Whose tongue was whose. Were those his hands or Gojo’s? 

Rocking down, he relished in how deep Gojo’s cock was able to drive inside of him. Was it just the lust curse? Did he make him crave being split open? Did it twist his thoughts until all he could think about was getting Gojo deeper and deeper? Get his seed embedded so far inside that it could no longer leave?

Nanami shuddered through another orgasm. This is a problem.  

“Does it feel that good?” Gojo smiled up at him, pale face flushed pink and eyes bright. He swiped at Nanami’s sticky spend splattered across his own stomach and smeared it back over Nanami’s trembling cock. “Should I replace all the come you’re losing? Is that part of the game?”

“Stop touching…,” Nanami trailed off, confused by his lack of overstimulation. His cock hardened immediately in Gojo’s loose grip. “Shit.” 

“So we are supposed to keep going.” Gojo licked his lips, twitching deep inside Nanami’s ass. “I better test it out, too. Sorry, Nanami, stay good for me okay?” Gojo closed his hands around his hips, grip brutally harsh as he abruptly pulled his hips back and slammed up and into him. 

Nanami cried out sharply, tears pricking his eyes. He scrambled for purchase but found nothing as he was held in place and Gojo fucked into him from below. It couldn’t have been the easiest position and it certainly wasn’t the most comfortable but Nanami found his thoughts growing increasingly debauched.

He could feel his chest and cock bouncing with every thrust, hard nipples sensitive against the cool air. His blunt nails dug into Gojo’s flexing stomach, uselessly holding on for dear life. 

Without warning, thick heat filled his stomach. 

Nanami’s eyes burst open, soundless cries caught in his throat. He milked Gojo’s throbbing cock for every last drop of come. Energy thrummed through his body in a way that sex had never energized him. The curse.  

Perhaps there were some perks to this. 

He sighed in satisfaction. 

The relief lasted all of a second before Gojo pulled out and tossed him back onto the sheets. Nanami struggled to orient himself. There was no need to worry though. Gojo was back on him immediately, rearranging their bodies and pressing Nanami face first into the bed. 

His slick cock was just as hard as it was before he came, rubbing between Nanami’s ass cheeks and teasing the swollen rim. 

“Think you were right,” Gojo laughed breathlessly. He sank back inside, displaced come gushing out around his dick. Moaning sweetly, Gojo curled over Nanami’s back and rolled his hips forward. “The curse definitely just wanted me to breed you. No middlemen needed.”

“Gojo- san —!” Nanami’s eyes rolled back as the lazy grinding abruptly became harsh and deep. He fisted the sheets and bit down on the nearest pillow just to stay sane. 

“It’s like all I can think about, Nanami,” Gojo mouthed at the nape of his neck, sharp teeth scraping over delicate skin, “is filling you up. Make you all sweet and soft and round right here. ” His hand splayed over Nanami’s lower abdomen and just over the tender skin above his aching dick. 

Dipping even lower, Gojo massaged the base of Nanami’s leaking cock, curling around heavy balls as he continued to slam into his ass mercilessly. 

Nanami felt the pillow grow wet with his tears, drool slipping from his parted lips as another orgasm tore through him. He couldn’t be sure if his cock even released anything. It certainly hadn’t softened. Not by the way Gojo was able to to wrap a needy hand around the shaft. 

“Gonna feed you til you can’t eat anymore,” Gojo murmured, lips curling against his shoulder. “It’s like this little curse is our baby, Nanami.”

“That’s horrifying,” he retorted, hoarse and slurring. 

Gojo just laughed. “You’re right. Let’s save the baby talk for after this.”

Nanami’s dreams were plagued with gushing semen and Gojo’s lascivious smiles.

Nothing new. Not since the curse afflicted him.

As he surfaced back to reality, his memories came back with him. His jaw ached and his lower body felt like it had been run over with a truck. Actually, everything hurt. Not a single thing didn’t hurt. 

He didn’t know when he fell asleep, or rather, passed out. Each time he had blinked awake, he was in a different position but still firmly speared on Gojo’s cock. It was as if the man couldn’t go soft. Maybe the curse hadn’t allowed it. Who knows.  

Nanami tried to roll over, wincing at the immediate pain spiking up his lower back. His head thumped against a warm chest. Tilting his head back, he found Gojo slowly waking up. 

As if it was the most natural thing in the world, Gojo leaned down to kiss him on the forehead. “Mm, tired. Let’s sleep more,” he whined, voice low and thick with exhaustion. 

“What time is it?” Nanami tried to roll away but gave up when his body protested. 

Heavy, clumsy arms hooked around his waist and hips, dragging him up against Gojo’s body. “Doesn’t matter. Nowhere to be,” he mumbled, sighing as their naked bodies pressed flush together. “Curse is dead.”

Nanami blinked, waking up a bit more. “You got rid of it?”

“Came inside you so many times,” Gojo giggled, “wanna know the count?”

“The curse emerged?” Nanami demanded.

“Not really,” Gojo kissed the furrow between his brows, the slope of his cheeks, the corner of his mouth. “Lots of cursed energy gathered down here,” his hand drifted over Nanami’s abdomen. “Didn’t belong to you, so I just,” he tapped the hard muscle and laughed, “Poof!”

Nanami dragged him into a proper kiss, tongues twining. He threaded his fingers through messy white locks, rolling them over until he had caged Gojo beneath him. “Thank you, Gojo-san,” he murmured, nibbling at his bottom lip. 

“Wanna thank me more, Nanamin?” Gojo moaned, wrapping his arms tighter around him. “Can’t fuck you again yet, though….” They exchanged more kisses, languid and just shy of sloppy. Their tongue curled and uncurled, lips wet and smacking too loud in the quiet.

“No need,” Nanami scoffed, settling comfortably against Gojo’s body. “You’ve bred me sufficiently.”

A surprised laugh rumbled out of his chest. Gojo rolled them onto their sides, cradling Nanami’s head to his neck. “Not yet. Gotta try again without the curse.”

“You’ve skipped several steps, Gojo-san.” As have I.

He yawned, smoothing Nanami’s hair down. “You’re right. Let’s go on a date instead of a mission next time. No curses.”

Nanami pressed a smile to Gojo’s throat, humming in agreement. They could discuss the particulars of their relationship another time. Perhaps over a proper meal together. Maybe at a bar with excellent drinks.

For now though, this was enough.
