It had all started very simply.

Kunigami Rensuke went to shower after several hours of weight-lifting, an activity which he often partook in alone, since everyone else in Blue Lock preferred to eat and socialize after their practice matches. It had multiple benefits, number one being that he got the gym to himself, and then he got the shower to himself, since everyone else was at dinner. He enjoyed showering alone, as there was no one to rush him and it allowed him to think in perfect silence, with only rushing water in his ears. Plus, when he went to eat dinner later, there was usually no one around, giving him solitude in three parts.

He took freezing cold showers. They soothed his aching muscles after another long, painful day in Blue Lock. The chill overwhelmed his senses, making him numb to the world, and to himself. The water washed away some of the ache clinging to his skin, loosening some of the hurt hard-packed into his flesh. It cascaded over him, drowning him in sensation so that he didn’t have to think anymore, relieving him of another kind of pain in the process.

It was his favorite activity of the day. 

Almost like heaven on earth.

And then Shidou Ryusei, demon bastard of Blue Lock, had burst out of hell to ruin it all.

Kunigami heard the door slamming open, but that in itself hadn’t immediately alerted him to the presence of the demon in the shared bathroom. Many of the other boys slammed their way in. Bachira, for example. Barou, sometimes, if he was hyped up or aggravated (sometimes with Bachira, sometimes with Nagi). Isagi, if he was in a heated argument with someone, whether that was Karasu or Rin, who was like a brick wall, never caring to get into it with him.

But the banging was accompanied by loud, obnoxious music.

Heavy metal, specifically.

It set Kunigami’s teeth on edge. How could anyone listen to a man screaming, raw-voiced and shrill, into a microphone, at top volume, and not want to hammer a fork into their own ear?

It filled the bathroom with its cacophonous timbre, spilling into every corner, staining every line of grout, inescapable and irrepressible, just like Shidou himself.

Kunigami tried to speed up his shower, even though he loathed to do so. But listening to that garbage for even ten seconds proved too much for him.

So nine seconds later, he was storming over to Shidou’s stall, dripping and pissed. There was a towel hanging up outside the shower, as well as a shower caddy, which had the offending waterproof speaker.

Kunigami slammed his hand on the walls of the shower.

“Turn that racket off!” he bellowed over the wail of the heavy metal singer.

A second later, a dark hand darted out, grasping at his radio. Shidou turned down his music, but only marginally. He threw back the curtain, flashing Kunigami in all of his naked glory, completely unashamed of his dripping nudity.

Kunigami grimaced as he looked him up and down, disgusted.

He wasn’t attracted to alphas, not in the least bit, and Shidou was pure alpha. Although he wasn’t as broad as Kunigami, he was still sinewy and strong, athletic, his body flexing with all kinds of muscles (even if he was a little lanky for an alpha). His dark, tanned skin was dripping from the shower, shiny and smooth, flawless in fact, as he clearly took care of it, and vigorously (Kunigami could see all kinds of lotions and skin wash in Shidou’s shower caddy, which would explain it). His blond hair was flat against his head as he stared back at Kunigami, an insouciant, irreverent disdain on his lips.

“Can I help you?” he said.

“Turn it down,” Kunigami said immediately. “And keep it down.” 

He pointed at the speaker to make his point. 

But Shidou just scoffed.

“It’s a free country.”

“No, it isn’t. Communal spaces are exactly that. Show some respect.”

“No one’s here but you, buddy. Why don’t you just piss off?”

His hand fell down, between his legs, scratching his balls. 

Right in front of Kunigami, the nerve of him. 

The ginger’s eyes couldn’t help but be drawn to his cock now. 

Big, veiny, and dark. Smaller than his, but still undeniably large. A complete, unwavering, unwavering alpha.

Kunigami could smell it too, his powerful scent, much stronger in the shower with all the moisture. Shidou always stunk up the field; he exuded nothing but pure alpha pheromones that distracted alphas, betas, and omegas alike. But this was a hundred times worse.

Kunigami’s nose wrinkled in disgust, his stomach flipping. 

He hated the smell of it. But it was oddly compelling too, in ways he refused to consider right now.

“I’m serious. Let people shower in peace. You can be as annoying as you want at home, but not here,” Kunigami said firmly.

He swallowed thickly, something like bile in his throat as he saw Shidou’s eyes drawing up and down him slowly, making no effort to conceal his interest.

Or the way they lingered the longest on his cock.

“I thought you gave up on the whole hero act,” Shidou said slowly.

Kunigami blinked, his eyes bothered by the heat and moisture of the shower.

“I thought you didn’t remember me,” he said.

“I didn’t. But I heard the sprout saying some shit about heroes or whatnot, so I figured that was your gimmick before I crushed you. Whenever that was.”

Kunigami couldn’t stop himself.

He took a step forward, crowding Shidou, pushing him backwards, into the wall.

Water came tumbling down on Kunigami’s head, but he ignored it as he gripped Shidou’s jaw, forcing his head back too. His powerful fingers clasped around Shidou’s throat.

For just a moment, he saw it. 

The delicate bob of his Adam’s apple. The sparkle in his eyes, because he was an insane fool, who loved the thrill of danger, reveling in his destructive ire.

Shidou liked it, the son of a bitch. He enjoyed being thrown around. Manhandled by someone stronger than him (because it didn't happen often). Just as when they'd first met, and he'd tried to hit Kunigami, only for Kunigami to block him, and throw him back.

Shidou swallowed, smiling slyly, lecherously even, arching his neck deeper into Kunigami’s hand.

Water spilled down his face, trickling across his cheeks, dripping over his chin. It soaked Kunigami's fingers, washing away his morals and his predilections.

His skin was already flawless, but now it looked shiny too. Through the distortion of the steam, Shidou almost looked prettier, some of his harsher edges worn down by the eroding force of the shower head. Shorter than him by a good amount too, not that Shidou was short, just Kunigami was tall. 

(Was he always this unjustly handsome, this unfairly beautiful, or was that just the atmosphere of the shower, the tension between them, the heat of the moment?)

Wet. Soaking wet, covered in leaking fluid.

Naked. 

Kunigami suddenly remembered they were both naked.

Water flattened his thick hair; he shook his head impatiently, sending droplets flying.

“What now, fallen hero?” Shidou said. 

He was breathing hard. 

With excitement, mostly.

Kunigami could see that.

Literally.

His cock was already half-hard.

“You’re a disgusting pervert,” Kunigami grumbled. 

“You’re the one who came into my shower,” Shidou pointed out, smirking.

Kunigami still hadn’t let go of his throat. He didn’t want to, not yet. Not when Shidou was grasping at his own neck.

But rather than trying to fight him off, Shidou’s fingers clasped at the back of his hand, rubbing his knuckles. His thumb stroked softly at the palm of his hand, teasing across his wrist. Even though he’d never felt more overheated in his life, Kunigami shivered.

“You’re a handsome guy,” Shidou said idly. “You must’ve really played like shit if I don’t remember you.” 

“Do you really not remember me?” Kunigami said. He thumbed at the base of Shidou’s throat, feeling his heart racing (or maybe that was his own). He derived a grim satisfaction from tilting his head back further and further, until its blond crown hit the tile. 

Shidou’s hair looked so long when it wasn’t spiked up. He still looked too much like an alpha, but with Kunigami’s hand around his throat, and Shidou not resisting, not one bit, well, maybe…

“Hm…no.”

Typical. 

He could’ve been saying it to bother him, but somehow Kunigami doubted it. That wasn’t the kind of guy Shidou was. Mindgaming and psychological warfare. No, he just was what he was, with no apology. A force of nature. 

Kunigami had been flattened by his raw, primal strength. Swept away by his chaos. Swallowed and spat out by his natural disaster.

Now, he had come back.

And he was just like him. Just like everyone else in Blue Lock.

So desperate for victory that nothing else mattered anymore, not who he used to be, nor who he would be someday in the future.

Perhaps that was why he did what he did next. 

Because he only existed in the present.

(And sometimes, not even there.)

He yanked Shidou towards him, his grip still tight around his neck, and bent down to bring their mouths together. In purely physical terms, he supposed you could call it a kiss. But they defied every other definition of the word. It was more like a crash of mouths, the warring of teeth, the mastication of saliva. Immediately, Shidou was fighting back, biting at his lips, trying to shove his tongue down his throat. His greedy hands scratched at the small of his back as he pushed himself forward, so they were chest to chest, their cocks brushing against one another, sending a disconcerting spark of arousal into Kunigami’s lower stomach.

Kunigami, for his part, had almost a stranglehold on him, both hands clasped around his neck. 

He had kissed girls before. He’d kissed boys before.

He’d never kissed like this. 

This felt more like a struggle to the death.

When they both had to breathe again, it didn’t relent either. Kunigami stopped, panting, but Shidou kept at it, only now he was attacking the ginger’s throat, nipping at his sensitive skin. Kunigami fought him weakly at first, but it felt good, in a perverse way, so his resistance was half-hearted, perfunctory, almost performative. Shidou’s punishing fangs gnawed on him like the rabid animal he was. A dog with a bloody bone, foaming and ready to be put down (and out of its misery). He was voracious and starving, insistent on scarring and mutilating, sucking and biting dark marks into his paler flesh, but it felt good the same way that lactic acid did, burning in his veins after a workout.

He felt present. Alive. 

More present and alive than he’d felt in a long time.

Pain and endurance were one and the same, not capable of existing without the other. To become strong, you had to slice and cut and boil and burn away the weakness. Harden your soft flesh into calluses. You had to push yourself until you broke, and then when you broke, the pieces had to be smashed back together into something monstrous and new. No longer agonizingly weak, but agonizingly strong. There was no pleasure part of the equation, only grim satisfaction as you consumed more of yourself, converting your weakness into power.

Kunigami was that fractured, malformed beast. Shidou was something purer, a savage and a devil, the breaker of beasts, but perhaps that was a good thing, and he never would’ve become stronger without being broken by him first.

But then, as Shidou Ryusei was so wont to do, he went too far.

Bit him too hard.

Kunigami yelped in surprise, shoving him away. He glared at Shidou, grasping at the cut on his throat, shallow, not terribly long. The blond grinned at him, all fangs, licking at his bloody lips. 

“Fucking bitch,” Kunigami said.

Shidou laughed, but didn’t reply otherwise.

That was fine with Kunigami. 

He preferred Shidou’s mouth to be occupied anyway. 

Or pressed into the tile.

Which it was, five minutes later. 

He pinned Shidou to the wall with his broad, muscular form, savoring the feeling of being so much bigger than him. Shidou might’ve beaten him on the field, but he had nothing on his superior weight or bone structure. He crowded Shidou, rubbing his cock between his legs. Scowling at his erect penis, as if furious at its betrayal.

Shidou’s thighs were so soft and wet. It almost confused his brain into thinking he was an omega. Almost. If he could ignore the hard, bulging muscles. The overpowering stench. The heavy cock and thick balls, swinging between them.

But then Shidou bent over, his hands on the tile, arching his back like an omega. 

And that helped.

It helped a lot. 

“You pathetic excuse for an alpha,” Kunigami grunted into his ear as he furiously rutted between his legs. But to his disgust, he couldn’t suppress the groan, deep in his throat, emanating from the explosion of heat in his lower gut, as his cock slid against Shidou’s ball sack. He reached around his thick right hip, feeling the pleasant dip of his muscles, the valley of his crotch. He found Shidou’s cock, rubbing him up and down from shaft to head,  his grip too tight, too harsh, so he could relish in his little whimpers of pain (that he definitely wasn’t playing up for Kunigami’s enjoyment, the little freak).

“I hate you,” Kunigami grunted into his ear after a particularly dramatic whine, followed by Shidou arching his back even more, rubbing his ass against his front, their cocks sliding past one another as Shidou bucked into his hand. It was incredible, the dichotomy of Kunigami’s feelings right now. 

He was hopelessly aroused and desperately disgusted with himself at his own arousal.

This was all wrong. Not just doing this with an alpha, but Shidou of all fucking people, the worst person he’d ever met.

And yet.

Worst of all was the knowledge, deep within his bruised and battered heart, that it wasn’t really Shidou he hated. It was what he represented.

And that was Kunigami’s fragility. His foolishness. His naivete. His inadequacy. His failure.

Shidou was bending over for him, completely unashamed of what he wanted… he didn’t give a rat’s ass what any other alpha thought, just so long as he got what he wanted. And what he wanted was the entire world. He didn’t give a shit about anyone else in it, but himself.

Kunigami would never admit it, in fact he could barely acknowledge it to just himself, but there was something to be admired in his arrogance. His unquenchable thirst and insatiable greed. 

If Kunigami had even a quarter of his drive, perhaps things would be different right now.

Perhaps he’d still be sitting with his friends. 

Messing around with Bachira, teasing Nagi and Reo, eating steak with Isagi again.

Talking to Chigiri.

Meeting him with no one else around… 

Kunigami’s heart twisted then, some of the nostalgia and yearning disappearing, replaced by the hatred that had become his fuel ever since he’d been eliminated from the program. He hated that Shidou chased his own pleasure, his own dreams, with such single-minded passion. Hated that nothing bothered him, not social pressure, nor societal pressure. All he wanted was to play ball and have sex, and he didn’t care about any of the rules associated with either of those things.

He was a true egoist, and a proper alpha, and Kunigami hated himself every time he looked at Shidou, because the reflection he saw in that distorted mirror disgusted him.

(Where’s your fucking fire, fallen hero? The flames that lick your flesh clean of all its wrongdoing, all its shame? Where’s your supernatural hunger, the monstrous, undeniably inhuman desire to surpass all the rest of these limited mortals? Your need to whip this world into bloody submission as it kneels before your feet?)

(Care to borrow some from the devil himself?)

The ginger striker gritted his teeth.

“Hate that the best you can do is stop me, not outplay me?” Shidou said, and Kunigami could hear the smirk in his voice.

“That is being outplayed, moron.”

“No, it’s not. It’s you being unable to do anything other than focus all your attention on me. I made you my bitch in that game.”

Shidou’s voice shook as Kunigami snarled wordlessly at that, letting go of Shidou’s cock in favor of grasping his hips. He dug his fingernails into his flesh, rutting against his ass, sliding his cock against his taint, staining the inside of his thighs with his precum for just a moment before the shower washed it away.

But Shidou kept talking, the annoying fuck. 

“You can’t beat my shots, you can’t score the way I can score, and the only reason you’re still here is because of a bullshit security blanket. It really eats at you, doesn’t it?”

“You’re antagonizing me because you want me to fuck the shit out of you, aren’t you?”

“It’d be nice.”

“And you call yourself an alpha…” 

“I don’t care about designations,” Shidou said, snorting derisively. “I care about what feels good, and alphas have a goddamn orgasm button up our assholes. You actually have a cock long enough to hit it, and I’m goddamn horny. Now shut up and prove you’re a proper fucking alpha, and fuck me.”  

Kunigami snarled at him again, seizing his hair and yanking his head back at an angle that had to be painful. He glared at Shidou’s back, focusing his ire on the dark-skinned striker’s bulging shoulder muscles, his thick, athletic buttocks, the rigid lines of his perfect alpha body. He hated how beautiful he was.

Whether it was in the shower, soaking wet and shining, or out on the field, exploding into the sky, a comet, a shooting star, a supernova, blowing away the entire universe.

He couldn't tear his eyes away from his dark furled hole. 

Small and inviting…and too tight.

Kunigami might hate Shidou, but he wasn’t a monster. 

“Do you have lube? I can’t go in dry,” Kunigami grunted, wincing at the embarrassment of having to ask after their heated exchange.

But Shidou was laughing. 

“Shea butter. In my caddy.”

Kunigami shoved him into the wall again for good measure, maybe in irritation, maybe in an insecure, performative sort of way, as if making sure he knew he wasn’t getting out of this now, and he would be staying in the shower until Kunigami was done with him. But Shidou didn’t protest either way.

He did the opposite of protest, in fact, when Kunigami returned with his bottle of lotion and began to palm at his firm backside. He wiggled his hips, as if to entice him.

Kunigami felt up his strong legs and powerful thighs first. Slapping at him, but not seeing anything jiggle, as he was all muscle and no fat. It felt good, though, like hitting a speed bag at the gym. No take (and yet, all give where it mattered). When he was done groping him, guiltily relishing in the firmness of his ass cheeks in his hands, he began prying at his entrance with his fingers, using the umbrella of his thighs to prevent their makeshift lube from being washed away instantly. One hand to hold him open, the other hand to penetrate him, sinking inside of him until the rest of him could fit.

Kunigami was immediately struck by how much tighter an asshole was than a pussy. Pussies were warm and soft and firm in their own way, but Shidou’s asshole was nothing but pure pressure, resisting the invasion of his first finger with the zealotry of the front line defending their homeland from sure destruction.

Kunigami was almost scared to continue pushing, to carve a path inside of a body that was not built to take him. He was a newly conscripted soldier holding his rifle with trembling hands, trained to  kill, but untested, unsure if he could truly do the job now that he was really here, staring his enemy down across the field.

But Shidou was moaning. Unlike his body, he wasn’t protesting.

“What are we, fourteen year olds?” he panted. “I can take more than one, dumbass.”

Kunigami scowled at his muscular back, the tension in his shoulders. That’s what he got for trying to be considerate.

He jammed his second finger in, hooking both of them inside of Shidou, his wrist twisting with the effort.

Shidou grunted, but not as loud as Kunigami would’ve liked (and would’ve deserved too).

Instead, he just bit his lip, giggling, as Kunigami continued to pry him open, pushing past firm, unassailable muscles, squeezing him open with the meticulousness of a surgeon.

It was very strange, fingering Shidou Ryusei in the shower. Just twenty minutes ago, the idea would’ve been sickening, but now, in the heat of the humid air, under water that was turning lukewarm, it was almost intoxicating, irresistible. He knew he should leave. He still could.

And yet, at the same time, the crash was already in motion. 

There were no brakes left. No hope for survival either. He had veered off course and now he would see his god.

Kunigami had barely wedged a third finger inside of him before Shidou got impatient.

“Good enough!” he barked over his shoulder. “Get this show on the road, alpha, or has your dick fallen off during all that prep?”

“Masochist,” Kunigami grumbled.

But it didn’t bother him.

There was a time when it might’ve. 

But not now.

He seized Shidou by the hips.

Kunigami smacked his right ass cheek hard, hoping to hear him yelp in surprise, but he was displeased to hear Shidou laugh instead, wiggling his hips back and forth again, as if telling him to give him his best. Well, he wouldn’t be doing that.

All Shidou deserved was the worst.

When Kunigami forced his way in with his cock rather than his fingers, he was slow. Exacting. Punctilious.

And it was a good thing too.

As much as Shidou clearly wanted him to just bend him over and fuck him with the momentum of a freight train, he really wasn’t ready.

It was actually uncomfortable for Kunigami to fuck something so tight, his cock feeling just a tad overstimulated, cramped even.

But it must’ve hurt Shidou a lot more.

He did wheeze, a surprisingly vulnerable sound coming from him, like he was actually distressed, his breath catching sharply, his insides tightening, as if he was in pain. Despite everything that had happened to him, what remained of Kunigami's heart still twisted at the sound, something cold dropping into the warm sea of his guts. He stopped, waiting for Shidou to tell him he was ok. 

(Weak, weak, weak, and you insist he's the fake alpha. Hypocrite. Fool.)

But after a moment, Shidou relaxed.

And he was humming instead.

Laughing to himself.

(Is that your strength, you blond-haired, pink-eyed, loud, laughing-mouthed demon?)

“Finally, you’re good for something other than being a pain in my ass,” he said, chortling at his own joke.

Kunigami ignored this, continuing to push inside of him.

Unbearable pressure. 

Like he was being sucked in. 

Suffocated.

But it was pleasurable too. Annihilation. Restriction.

It was painful. And like some painful things, it was good.

The more he fucked into Shidou, his powerful hips beginning to roll, pushing deeper and deeper, the easier it got. The better it began to feel.

As much as he didn’t want to admit it, it did feel, marginally, better than fucking an omega’s pussy. Even if the smell was wrong - and the smell was an important part of the whole process - it felt amazing to fuck something so cramped and small, invading somewhere he did not belong.

Shidou’s enthusiasm helped too. 

Most of the omegas he’d fucked were cute. Needy. They did everything omegas were supposed to do, mewling and arching their backs and swaying their hips and begging for more.

But Shidou was more aggressive. 

He made demands of Kunigami. 

He didn’t just lie (well, stand) there. 

He was bracing himself against Kunigami’s rougher thrusts, both feet firm on the wet floor, his fingers curling into the tile, water spilling down the back of his neck, leaking from his blond hairline.

He made ragged, but encouraging sounds, his voice completely broken by half moans and clipped panting, sharp little ahhs, breathless and exhilarated, like he was on the ride of his life.

Shidou pushed back sometimes too, splitting himself on Kunigami’s cock when he deemed he wasn’t going deep enough, or hard enough, or fast enough. 

Kunigami gripped Shidou’s waist in his long, powerful fingers, feeling the heat of the moment really getting to him, his entire body tingling with sudden energy and euphoria. He held him steady, as if forcing him in place, then dragged his hands lower, digging his fingernails into his hips. Kunigami yanked Shidou back onto his cock, forcing him to take it harder than before. His hips slammed forward in perfect conjunction, violently colliding with his wet backside, making a thick, lewd slapping sound.

One particularly brutal thrust drew a proper shout from Shidou as Kunigami slapped his right cheek in conjunction with it. 

The ginger striker twitched inside of him at the sound, hopelessly aroused by its breathless helplessness, the wordless tone of surrender. It wasn’t in an alpha’s nature to hear the scream of another alpha and be aroused rather than furious.

But they were beyond designations at this point. 

Shidou didn’t care about them and he’d managed to confuse Kunigami into marrying his anger with his arousal. In this moment, Kunigami couldn’t remember anything about designations either.

All he knew was that he was fucking something warm and alive. That was all that mattered.

He felt disgusting. But maybe there was comfort in feeling disgusting. In sliding into your own degradation with an open heart and mouth, swallowing the filth, and letting it mingle with your own.

(Somehow, he felt cleaner now, being disgusting with Shidou, than he had felt showering alone.)

Shidou began taunting him. Insulting him. Teasing him. Trying to goad him into fucking at a different tempo, to thrust slower or faster, change his angles.

Saying things like, “Is this how you fuck omegas? No wonder you clearly don’t have one waiting for you at home.” 

Or “I know you can do better than that. All that muscle and you can’t carve me into a million pieces? Such a waste.”

And worse, "Fuck me like you still deserve to be here, you failed striker."

It was infuriating, but sort of easy to ignore when buried eight inches deep into Shidou’s guts. The mean words rang a little hollow when they were interspersed by wet little pants anyway. Moans of pain and pleasure, as Kunigami’s thick cock spread him out, making his previously pristine little hole into something wide and deep, no longer a scratch, but a fatal wound, splitting him apart just as Kunigami had always wanted to break him (just on the field, and not in here).

Kunigami was more bothered by his smell, his nostrils stuffed with the stench of his alpha scent. It felt good to be overwhelmed, but it felt wrong too.

Unnatural.

But he wasn’t going to stop.

He couldn’t. 

Not until he felt the tingle in his belly.

The electricity sparking, threatening to light a round of explosives in his gut and blow him to kingdom come.

He began to pull out, knowing better than to knot inside of an alpha.

Only for Shidou to say, “Cum inside me.”

Kunigami’s brow furrowed. “What? No, I can’t.”

“Who says you can’t?”

“We- No, it’s not right-”

“Just fucking cum in me, you absolute pussy,” Shidou snapped. “That’s the best fucking part.” 

“No, fuck-”

But it was too late.

Shidou had distracted him, stopped him from pulling out properly, and he could feel his cock swelling. He couldn’t cum here, halfway pulled out. So he forced himself in deeper, instinctively seeking out a womb that wasn’t there. 

Even though he hadn’t wanted to do it, at least it shut Shidou up.

The alpha actually screamed in surprise as Kunigami’s cock rammed against his prostate, full hilt, clumsy and a little too strong in his panic.

“F-fuck,” Shidou swore, and Kunigami felt his cock twitching again at the crack in his voice, pained and uncomfortable. “Oh god, you’re fucking big.”

Hearing him admit it might’ve made Kunigami smile.

But he was too distracted by the feeling of unbearable tightness. Shidou’s walls contracted around him, squeezing him like a boa constrictor.

His knot swelled fast, further increasing the feeling of being crushed, expanding inside of Shidou, causing him to whine pathetically.

Shidou threw his head down, the nape of his neck arching obscenely in front of him, as if he was begging for a mating bite, his hands still outstretched, fingers pressing against the wet tile.

How Kunigami had always loved the nape of the neck. Smelling the scent glands there, stronger than any other scent glands on the body. For the first time since stepping in the shower with him, Shidou sounded, looked, and smelled like not-an-alpha.

Not quite an omega. But definitely not an alpha. Whimpering and whining on his cock…begging for him to keep going. To grind him into unrecognizable dust.

For the first time since he’d stepped in the shower with Shidou, Kunigami felt at ease. Confident. Almost smug. So this was what it felt like, to tame the wild and untameable Shidou Ryusei.

To make him his bitch.

He wondered if Itoshi Sae felt the same way, or if it was different when you were an omega taming an alpha.

Kunigami grinded in deeper, draping himself over his back like the king of the jungle, asserting his dominance over every other living thing. Shidou tensed as his knot nudged against his prostate again, letting out another un-alpha-like whimper. His toes curled, his back bending, body writhing slightly as Kunigami pinned him against the wall, completely enveloping him with his broader form. Kunigami had never felt larger. More powerful. 

Fucking an omega should make an alpha feel like the strongest, most dominant creature alive. But maybe omegas were easy. They were made to submit. To roll over and take it when an alpha demanded it.

Forcing an alpha to submit was something different. They weren't made to submit. They were a challenge. A struggle to completion and defeat, every time. Maybe Kunigami had been cucking himself of this feeling all along. Maybe Shidou was onto something. Maybe, like before, he knew more than Kunigami. Had sensed the mysterious and unnatural world, deep beneath the surface, where only desire and egoism and Id existed.

He’d never felt so deep inside of someone. He could feel himself gushing inside of Shidou, filling him up, and even though he didn’t have a womb, his inner alpha was content.

“Some fucking alpha,” Kunigami growled in his ear, his teeth scraping lightly against the sensitive lobe, causing Shidou to shudder again (but he wasn’t sure if this was excitement or pain this time). “Letting another alpha bitch you like this.” 

(Bending over for it...you’re the pathetic one.) 

(You’re also stronger than I could ever be.) 

Kunigami seized his soaking wet blond hair, yanking his head back so he could nip at his neck. Run his teeth along the scent glands on his throat.

Teasing a bite that both of them knew he’d never give him. 

He ran his tongue up and down his dark skin as he continued to spill inside of the other alpha, his cum ebbing and flowing like the tide as they waited patiently for him to empty himself. 

Shidou hummed in contentment, having gotten used to the intrusion. He was almost leaning back into Kunigami now; the ginger alpha supported his weight. 

Letting go of his hair in favor of wrapping his long, muscular arms around his stomach. 

As if Shidou had a womb that he was currently filling. 

“Pathetic,” Kunigami said lightly, nuzzling the back of his neck more gently now, more friendly, probing rather than threatening or seductive. 

But his voice was soft.

And Shidou got the message.

That this time, Kunigami wasn’t referring to him.

The next time Shidou saw Kunigami, it was in the hallway of Bastard Munchen’s stratum. 

And he smirked at him. Raising his hand in greeting, winking to be cheeky.

But Kunigami approached him like the cloud of a quickly approaching dust storm, ominously bearing down on him, ready to tear up his storefronts and churches. He beelined right for Shidou, seizing his arm in a punishing grip. Normally, Shidou might snarl at him, fight back, demand to know what the fuck he thought he was doing. But now, he just kept smiling, allowing himself to be dragged into an old, unused storage closet.

Kunigami shoved him inside, then slammed the door shut behind them. Shidou leaned against a shelf, eyebrow raised in amusement as Kunigami fumed, his fists clenched, shoulders hunched, his posture godawful against the metal shelves.

“Is it true?” Kunigami finally demanded after a few minutes of heated silence. “You’re an omega now?”

Shidou snorted. So that was what this was about. 

Ha. About time. Shidou had been flaunting his new equipment in the locker room for days now, flashing every other alpha and omega and beta in his stratum, hoping it would get back to him. 

(Always a step behind me, as usual, Rensuke.)

Shidou leaned back, against the shelf, fumbling with the drawstrings of his pants. 

He shoved his shorts and his underwear down in one go.

Kunigami’s eyes zeroed in on the area between his legs, wide and horrified and awed. 

Where before there had just been a nice, decently sized, tanned alpha cock, now there was still a cock, but it was noticeably smaller, more withdrawn. And underneath his once proud head, nestled within a forest of blond pubic hair, was… 

Shidou burst out laughing at the look on Kunigami’s face, the wonder, confusion, and disgust at the sight of his newly acquired pussy.

He laughed so hard he almost fell down on his ass, tripping on his shorts, bunched up around his feet.

“This cannot be real,” Kunigami said, his voice panicking, cracking, dragging his eyes away from Shidou’s slit to seek out his amused eyes. “The guys were- they were saying you smelled like an omega now and that you were parading around with a- with- but I thought they had to be messing with me- I mean, messing around-” 

Shidou shrugged. “Obviously not!” 

He slapped his hand against his own slit, as if to emphasize the new truth of his world. Kunigami couldn't tear his eyes away from his folds, which were slick, as shiny as his flesh that day, in the shower, soaked to the bone.

“But-but bitching isn’t-”

“It’s not common, but it happens every now and again,” Shidou said easily, whistling to himself as he began to poke at his own folds, pulling up his penis to inspect himself. “Don’t get too cocky, Mr. Big Dick. It has nothing to do with you. Sometimes alphas with strong pheromones can induce powerful hormonal imbalances that result in designation shifts. I might’ve been leaning a little more towards an omega than the common alpha in the first place. Our little shower rendezvous was enough to tip the balance. Cool, huh?”

“No, NOT cool,” Kunigami snapped. “Why are you ok with this? Did you really have no pride as an alpha at all? Doesn’t this bother you? I- I basically mutilated you!” 

Shidou’s eyes snapped up to his face, no longer lingering on his own genitals. “What? No, you didn’t. It might not be common, but it is natural. Didn’t hurt, by the way. Felt kinda achy for a few days, got some mood swings, some stomach cramps, but nothing too crazy.” 

“But-but you-”

“I wasn’t kidding when I said I don’t buy into that alpha superior omega inferior bullshit,” Shidou said, rolling his eyes. “It’s stupid. Having a pussy won’t kill me or affect my soccer skills, so why should I care? Plus, it’s kind of fun. Look what I can do!”

He reached between his legs and plunged his fingers inside of himself. 

Kunigami almost passed out, he was still so disgusted (and maybe a little aroused, incapable of looking at the slit between Shidou’s legs without becoming as hard as a rock). 

He turned around in a daze, reaching for the door handle.

But Shidou slammed into him, tackling him, yanking him away from it. He threw him against the opposite wall and glued himself to his front, his small cock nudging playfully against Kunigami’s practice shorts. 

“It’s really fucking hot, seriously,” the blond panted in his face. He was fingering himself. 

Crowding Kunigami into the wall and playing with himself, right in front of him. 

Kunigami’s brain short-circuited, his revulsion melting into a slick, sticky wet arousal…that was already staining his pants as readily as Shidou was staining his own legs, dripping like a faulty fountain.

“I’ve always wanted to know what it felt like to have a pussy! I used to beg Sae to tell me what having a heat was like, but he always just told me to shut up and fuck him. But now I know! And he’s gonna love this when I show it to him-” 

“Shidou, I’m sorry, I didn’t mean for-”

“It’s ok, fallen hero! It’s actually one of the cooler things you’ve ever done. I didn’t know you had it in you, stud. Ha!” 

Shidou withdrew his fingers, a long line of slick connecting his index finger to his pussy for a moment. 

But then he was shoving them in Kunigami’s face. The ginger yelped, but it was a mistake, opening his mouth.

Shidou shoved his slick-wet fingers into his mouth. 

“I taste good, don’t I? Try it!” 

Kunigami spluttered, having to bite him so he’d remove his fingers. But he couldn’t deny it, not with Shidou standing right there, staring at him with perturbed pink eyes. 

Shidou tasted so much better than he’d tasted three days ago.

Still a little musky, with the heady remnants of an alpha’s scent, but sweeter now.

More…delectable.

Kunigami swallowed his slick, intrigued by its thick texture, its sweet, almost syrupy taste. 

Then, he stared back at Shidou.

Who was watching him intently. 

Licking his lips. 

“Say…you wanna give the new girl a spin?” 

Shidou reached down with one hand, sliding his fingers inside of his slit, prying himself open for Kunigami’s viewing pleasure.

And even though he knew this whole thing was a mistake, and that Shidou was no good, and especially no good for him, he watched. 

Watched Shidou rubbing himself, moaning loudly, performatively. Gathering slick on his fingers and palms, his thighs so wet, droplets of moisture sliding down his legs, rolling to the ankles, and staining the floor.

But his eyes gleamed brighter in that storage closet, as he stared at Kunigami with a manic glint, the gaze of both predator and prey. 

“I’m still myself. Still Shidou Ryusei, no matter what,” Shidou whispered. 

He withdrew his hand from between his crotch.

Throwing his fingers up behind his head, not caring about staining his hair with his own fluids (they actually accentuated his spikes a little). 

“You might be a big loser… but you didn’t mutilate me. Didn’t ruin anything. I just go with the flow, man. And this is just… life’s next big adventure.”

He smiled, giggling to himself, his golden hair flashing in the darkness. 

“So. What do you say? Want to try it out? I know I do. I know what it’s like having it in my asshole. But now I can see what it’s like to have something in my pussy.” 

Kunigami should’ve said no. Should’ve turned on his heel and left him in the closet with his strange new anatomy. But seeing as Kunigami was responsible for that anatomy…even though he would never do it again… he decided that he could do him this one favor. In compensation for his fuck-up.

Never mind that he was painfully hard and his gaze was drawn to Shidou’s slit like a magnet finding its opposite pole. That had absolutely nothing to do with it.

Shidou sighed, groaning lightly in Kunigami’s ear, as the ginger pressed him against the wall once more, dragging one leg up, around his waist. He fumbled with his shorts, yanking out his thick cock. Pressing it against Shidou’s folds, but not quite penetrating him yet. Instead, he just rubbed their cocks together. Remember how this all started. Wondering how it’d end. 

He had to admire Shidou. He still hated him, of course. But he could admire and hate him. It was impossible not to be impressed by him.

Only Shidou Ryusei would find himself forcibly turned into an omega and not be bothered at all.

Only Shidou Ryusei would be amused by this, rather than horrified or accusatory, cursing Kunigami’s entire lineage.

Only Shidou Ryusei would, upon finding himself now an omega, chase after the very alpha who had made him one.

Kunigami still didn’t like him. But he didn’t have to like him to fuck him. 

When Kunigami pushed inside of him, and Shidou purred, soft and delicate just like an omega should be, just with the curl of a still alpha-like growl at the edge of it, he only had one thought. 

Whether he’s an omega or an alpha… Shidou Ryusei is always a good lay.

"You know," Shidou panted into his ear. "If you decide you don't like this pussy... at least I still have my asshole. As a backup."

Kunigami couldn't stop himself from huffing sharply, almost a snort of amusement.

Moron. Fool. Pervert. 

But he might take him up on that.

"And if you're feeling - ahhh - fucking fun today, instead of boring like every other day of your life... maybe you'll try letting an omega fuck you in the ass with his cock, how about that?"

"Fuck you," Kunigami snarled, instantly on edge again. But he was grinning too. More of a snarl with curled teeth.

Shidou Ryusei. An enigma and a pervert, no matter what his designation was.

(But maybe he'd try it. Why the fuck not, when they'd already come this far?)
