The latest radio pop song has a jazzy flair to it which compels Karma to hum along. He sways to the music and taps his fingers on the steering wheel. He sits slumped forward to rest his cheek on the apex of the wheel. He’s looking left, watching the elevator door of the parking garage from beneath the low hang of his hood. 

The hood of his dark gray coat is to cover his hair. He has disposable gloves pulled up over the edges of his sleeves - duct-taped into place to prevent any chance of them coming off. He won’t leave behind fingerprints, won’t get blood under his nails, the scent-suppressing patches won’t fall off, and he won’t expose the tattoo on the inside of his wrist. There’s a kitchen timer set on the dashboard that is ticking down to get everything just right - no mistakes.

Three floors deep into the belly of Shinjuku, brass music swells just as the elevator pings. Karma flexes his fingers once then hops out of the car. He leaves the music playing as he walks around to open the trunk. The back seats are flattened and Karma takes his time smoothing out the plastic that covers the carpeted interior. 

In his peripheral vision, a couple stumbles out of the elevator and into the garage. An alpha and omega from the party above. The omega is in a tight, sequined dress and appears to barely be conscious, leaning heavily on their alpha companion while struggling to get their feet under them with each step. Even with their heels clopping all over the concrete like a newborn fawn, they’re a pretty thing with bouncy hair, creamy skin, long gloves, and a skirt that rides up their thighs. Karma takes a deep breath, imagining that omega’s smell, and his mouth waters. It’s hard to be patient. 

The omega’s companion looks buzzed and is the abrasive type. He’s not wearing any patches to inhibit his alpha stench from stinking up the stale garage air. He’s dripping with jewelry and drooling over his newest helpless omega. No doubt he’s dreaming of that omega’s skin just as much as Karma is. Except he’s not as charming as Karma. Oh, and he’s a drug-pusher for one of Shinjuku’s up-and-coming gangs. Karma’s done his research. This alpha goes to nightclubs to get as many people as possible to pass around free samples. Then, he picks up a free sample of his own in the form of any young omegas who are too twisted to smell the shit that’s whisking them away. Karma knows the type well enough. 

The couple stumbles towards Karma who is pretending to do something important in his trunk as he winds rope over his hands. The alpha doesn’t suspect a thing. Alphas never think they have anything to fear. The clumsy omega stumbles badly on their heels, falling towards Karma. They’re gripping the silk shirt of their alpha companion for support, causing the alpha to sway with them. 

In less than a second, the sleazy alpha, Karma, and the omega disappear into the trunk. 

Ready for a struggle, Karma wrestles the alpha face-down into the plastic while the rope is barred across his neck, choking out any unwanted sounds. The beautiful omega and Karma’s ride-or-die, Nagisa, drops the intoxicated act. He slams the trunk shut. 

The alpha’s sobered up enough to put up quite a fight. He wriggles like a centipede beneath Karma but can’t buck him off. Though the worst of it is really the alpha’s stink. Nagisa’s quick to grab the alpha’s ankles and bind them with another length of hemp rope. Soon after that, the man’s wrists are bound to his ankles, leaving him a furious but harmless maggot squirming over the car floor. Karma stops choking him to stuff a sock in his mouth. 

“Phew,” Nagisa sighs as he kicks off his heels. “Oh man, these were killing me.”

Nagisa leans back against the wall and rubs his feet as though he’s just finished a long night of partying. He ignores the furious gang member’s muffled swears which are competing with a radio ad for the latest mattress. 

“Sorry babe, I’ll try getting you a new pair soon.” 

They both know that’s the fourth pair in a month. Karma’s starting to think all heels are just like that but he’ll keep trying. Nagisa just hums and adjusts his elbow-length satin gloves. 

Karma reaches into their black backpack and pulls out a cheap Polaroid camera which he passes to Nagisa. For himself, Karma pulls out a disposable box cutter. The alpha’s eyes widen and he looks between Karma and Nagisa. Once Nagisa’s ready with the film, Karma removes the gag. Normally they don’t do messy jobs, but there are always exceptions. 

“What- what the fuck is this?” The alpha rasps. “You… you bitch. ” He hisses at Nagisa. “You set me up!” 

The man’s chest is heaving, having exhausted himself with his struggle. Nagisa, right as always, looks deeply unimpressed. 

Karma extends the blade of the box cutter and presses metal to the man’s cheek, adrenaline pumping to his fingertips and stretching his lips into an excited smile. 

“Really? Any more revelations?” Karma prompts. 

The alpha tries to arch away from Karma’s knife but Karma follows, pressing it into his skin more. 

“You-! Who sent you? Was it one of the Color Gangs? You guys are fuckin’ dead!”

A flash lights up the trunk as Nagisa snaps the first photo. 

“It wasn’t a Color Gang but any of them are welcome to take the fall for it - assuming you're important enough for your gang to avenge,” Nagisa says as he waves the printed photo into development. 

He looks at the picture and must be satisfied with it since he tosses it to the side and reloads the camera. Karma’s concealed hand, the knife at the alpha’s cheek, and the fear in his eyes are all in focus well enough. 

“You made someone mad. Mad enough that we’re getting paid extra to make this a mess.” Karma explains. He is speaking slower consciously as he tends to talk too fast when he gets excited. 

“Any ideas?”

“Fuck you!”

Nagisa only likes to do clean kills and their client paid a lot of money to make it slow. So, Karma’s the one with the knife. 

Karma looks back at Nagisa who twirls his finger, signaling that the first act of the show is good enough and they can move on. With that, Karma shoves the gag back in the man’s mouth, careless of chipping his tooth. Karma grabs the man’s jaw to hold him still so he can drag the blade down the man’s cheek. A bleeding gash trails down his face like the mascara tear-tracks of a young and abused omega. Perhaps there were so many possibilities for who could have hired Karma and Nagisa that the man couldn’t guess. 

Muffled screams accompany another Polaroid flash. 

When Karma and Nagisa were five, they met on the top of the playground slide. Nagisa wanted to go down the slide while Karma was having too much fun climbing up it. Nagisa scolded Karma for not using the slide right but somehow they ended up with their shoulders squished together as they went down. Squished together they stayed, long before either of them presented with their secondary genders, and long after. Their happily ever after just turned out a little different from most alphas and omegas. 

Nagisa pops open the bottle while Karma scrolls through the TV guide. There’s still plenty of cash from their last job to keep this nice hotel room a while longer. 

“Hey look, they’ve got Killing and Maiming III on here,” Karma says happily. 

“Wow, lucky us.” Nagisa rolls his eyes. 

He pours two cups of sake for them to drink with their sushi. They sit in bed and eat with their fingers while Karma has a laugh over the prosthetics used in the movie. A rubber arm flies across the scene with a spray of fake blood raining down on the victims. 

At the bottom of his first cup of sake, Nagisa feels dizzy. He looks over at Karma who’s licking wasabi off his fingers and leans his weight into him. 

Nagisa hums along to the after-credits of the movie as he lays back in bed, head just below the pillows. He spreads out his arms over the covers and drags his hands up and down to feel the texture. Drinking always makes him feel warm and sleepy. Nagisa blinks slowly, alcohol weighing down his body and his mind. He yawns and closes his eyes. He doesn’t bother opening them when feels Karma get up and go to the bathroom. 

The weight on the bed shifts as Karma climbs on top of Nagisa. His hands and knees are braced on either side of Nagisa’s body, caging him in, and Karma nuzzles into Nagisa’s neck to kiss it. Drinking doesn’t make Karma quite as sleepy as it makes Nagisa. 

“Fuck,” Karma groans into Nagisa’s neck. 

The bridge of his nose drags over Nagisa’s tendons as Karma sniffs his scent gland. His breaths come faster and shorter as his desperation grows into a drooling beast. The smell of alcohol mixes with their scents. 

Nagisa’s been Karma’s omega for a long time. Not being officially claimed doesn’t make that fact any less true. Karma’s twitching erection pokes up the bottom of Nagisa’s shirt and oozes precum as the head glides over his soft stomach. Nagisa remains limp and purring beneath Karma. Despite him being an alpha - or because of it - Nagisa’s at ease laying under him. None of the disgust that Nagisa feels when luring in targets is there when it’s just him and Karma. The feeling of I hate alphas which simmers just beneath Nagisa’s skin most of the time evaporates. Even when Karma’s drunk, and drunk alphas are usually the most disgusting of all, Nagisa trusts him. He doesn’t mind Karma touching him while he feels slow and sleepy. 

Karma’s hands trail down Nagisa’s sides and squeeze over the flesh around his hips. Nagisa purrs as Karma lifts one pliant leg to change the angle so he can hump Nagisa’s inner thigh. Nagisa turns his head to the side to tuck his nose into Karma’s hair. He breathes in the scent deeply as Karma’s hand keeps moving, pushing down Nagisa’s boxers. Two of Karma’s fingers trace Nagisa’s folds then rub his entrance, getting wet. Nagisa hardly noticed how his arousal grew when Karma climbed onto him. Nagisa notices now, angling his hips and moaning softly as Karma massages around his clit with wet fingers. 

Nagisa squirms under the touch, moaning softly as he grinds against Karma's palm. Karma knows just how Nagisa likes it and dedicates both hands to Nagisa’s pleasure. Karma uses one hand to give attention to Nagisa’s clit while using the other to pump two fingers into him, massaging his insiders. The only distraction is Karma humping Nagisa’s thigh but it’s not too much of a bother. He’s warm and sleepy, feeling good in a drowsy way as Karma brings him to a lazy orgasm. 

“What’s got you all worked up?” Nagisa whispers. 

“Thinkin’ ‘bout when you stabbed that guy…” Karma slurs, still rubbing his face in Nagisa’s neck. 

Nagisa didn’t stab anyone on their last job, did he? He wouldn’t forget something like that, right?

He chuckles. “Because of the movie?”

“Yeah…” Karma sucks on Nagisa’s neck - no teeth. 

Nagisa places a hand on the top of Karma’s head to push it down, making him suck on a less visible area. 

“You’re going to have to be more specific,” Nagisa whispers. 

“That time that one guy got free. The one whose tongue I cut out. He was trying to run through you and was drooling blood everywhere. Ah, I was so mad when he bumped into you. But then he just…” 

Karma laughs, drunk and strange as he’s always been as he recalls the scene.  

“But then he just dropped to the ground. I thought it was the blood loss but then I saw the big hole in his fucking gut because you twisted the knife before pulling it out.”

The way Karma talks about Nagisa’s actions always sounds like a fantasy. Karma always recalls so many details it’s as though he’s making things up. Nagisa stabbed someone with a hunting knife and twisted the blade in his guts to ensure his death - that can’t be real. It seems much more like something Karma would dream up than an act Nagisa would commit. Karma reminiscing over it like this is so strange, so weird of him. Just one of Karma’s little quirks. It doesn’t bother Nagisa to hear it. 

Nagisa threads sleepy fingers through Karma’s hair, humming idly as he listens to what’s just another one of Karma’s weird stories. 

“It was so hot,” Karma moans and drags his teeth down Nagisa’s neck. 

A thin line of Karma’s drool runs over Nagisa’s collarbone and down his shirt. Nagisa laughs a bit as he feels a little ticklish from it. 

Karma switches from stretching the collar of Nagisa’s nightshirt to sticking his head under it. His tongue licks up the messy line of drool then bites down on one of Nagisa’s pecs around his nipple. 

“Not so rough, Karma,” Nagisa whines. 

Karma drags his tongue over the bite and Nagisa’s hardened nipple. He can feel one of Karma’s hands trail down for Karma to stroke himself, the head still pressed against Nagisa’s inner thigh, but no higher. 

“Nagisa,” Karma whines back. His tone is specific and familiar.

Nagisa laughs more fully this time. Karma only does that when he wants one thing. 

“Karma, you’re not gonna get me to do it by bothering me.”

Karma puffs hot air against Nagisa’s chest, his hand stilling. 

“Nagisa, I want it.”

“Alright…” Nagisa pats the top of Karma’s head. “Turn around.”

Immediately, Karma’s head pops out of Nagisa’s shirt. He helps Nagisa sit up against the pillows. Nagisa yawns again but settles, parting his knees.

Karma turns so his back is to Nagisa and he lays between Nagisa’s legs. He lays slumped with his shoulders on Nagisa’s abdomen and his wet, throbbing erection begging for attention. Nagisa doesn’t give it any, knowing that’s not what Karma is asking for. 

Nagisa wraps an arm around Karma’s neck from behind. At the same time, Karma grasps the shaft of his cock, shuddering in anticipation. Karma’s chin rests on the crook of Nagisa’s elbow as Nagisa’s bicep and forearm pinch the sides of his neck. There’s nothing pressing on Karma’s windpipe as Nagisa squeezes, but it still constricts his breathing. 

Karma’s hand flies in a blur over his cock while Nagisa chokes him from behind. Nagisa purrs as he scents his alpha, enjoying the contact and intimacy of Karma’s weight as he chokes him. Karma spurts several thick shots of precum as his breathing gets thinner, most of his moaning weak and small as his mouth gapes. Nagisa nuzzles Karma’s hair and the back of his ear leisurely. He drags his tongue over the outer shell and kisses it as Karma’s body shivers and spasms between Nagisa’s legs. Yes, even drunk enough to want to pass out, Nagisa feels totally at ease with Karma. Karma’s Nagisa’s alpha and Nagisa loves him. Nagisa can’t even remember what it was like to not be in love with Karma. 

Nagisa sets his lips against Karma’s ear - kissing it tenderly. He can tell Karma’s getting close. 

“I’ll kill you,” he whispers lovingly. 

Karma chokes out a sob as he orgasms, shooting cum over the bed and dribbling it over his fingers. The room fills with the scent of a strong alpha as Karma pumps his cock wildly for more. Nagisa releases his arm, letting that strong alpha gasp for air and go limp as he swoons from the head rush. 

Karma groans and wipes his hand over the already ruined sheets as he turns over. He lays with his face in Nagisa’s stomach, clinging to and nibbling on his waist. Since Karma seems fine, Nagisa settles his fingers in Karma’s hair and goes to sleep. 

It started in mid-summer six years ago on a balmy Friday night. Karma was in his room alone, skimming a reading assignment with his parents absent as always. His phone rang and since it was Nagisa’s caller ID, Karma answered. What he thought was going to be a typical night distracting Nagisa from his own home life changed into a pit of dread as Karma heard Nagisa’s first ragged breath. 

“K-Karma…” Nagisa’s wet voice crackled through the receiver. 

Karma stood up immediately with the instinctive need to help but having nowhere to go began to pace. 

“What’s wrong?” 

“I- Karma, I don’t know what to do… I… I think I k-k… I think…” Nagisa sobbed again, his breathing faster. 

“Where are you?” Karma tried instead.

“I’m… I’m in Shinsekai. An alley by the expressway..”

Karma got ready in a flurry, stuffing his utility knife into his pocket and running directly into his shoes as he dashed out the door. All of his instincts were ignited - protect, fight, run - anything and everything to make his omega happy again. 

“Okay. Stay right there and stay on the call. I’m coming.” 

“Okay…” The miserable warble of Nagisa’s voice caused cracks to form in the base of Karma’s mind. “I didn’t mean to… I didn’t…”

“Whatever it is, it’ll be okay,” Karma promised desperately. 

He was panting into the receiver as he ran, knowing exactly where Nagisa was and too out of it to catch a bus. 

Their next job is the murder of a contentious politician who is growing in popularity too fast for their client’s liking. For some reason, it’s even easier for Nagisa to lure that man into an empty hotel room than most. All he had to do was look the part of a nervous college intern and the next thing he knew Karma was sealing the politician’s fingers into a plastic bag to ship to their client.

Back in their new room, a motel far worse than the last, Nagisa sighs in relief as he unpins the brunette wig from his hair. Once it’s free, he waves his hands over his sweaty scalp to cool down and kicks the heels off his aching feet. After that, he unbuttons the sensible blazer he wore for the part, shrugging it off to reveal a thin, white tank top.

Karma comes up behind him and blows a cool stream of air on Nagisa’s head. Nagisa looks up at him and Karma places a water bottle in his hand. 

“Thanks.”

Karma hums and settles his hands on Nagisa’s waist. He sways them together while Nagisa sips his water. 

“You know how I feel about you in a skirt, baby.”

“You along with seventy percent of the alphas we get hired to go after,” Nagisa replies flippantly. 

“Is that bad?” Karma kisses Nagisa’s damp hair and Nagisa can feel the smile there. “Sorry, I’m like other alphas.”

Nagisa turns around in Karma’s hands to face him, his chin on Karma’s chest. 

“You’re almost like other alphas,” he trails a finger across Karma's pecs. 

Karma’s smile broadens as Nagisa flirts back.

“Almost?”

Nagisa nods. 

“You’re different because you’re mine.”

Nagisa lifts up onto his toes to kiss Karma. Karma leans down to meet him. 

Karma scoops Nagisa off his feet and spins them toward the bed. Nagisa’s skirt flutters around his thighs. Karma sits on the bed with Nagisa in his lap. He pushes up Nagisa’s tank top to expose the padded bra beneath. Nagisa’s breath hitches as Karma gets both hands under his bra to grope Nagisa’s flat chest. With Karma, the “surprise” that Nagisa’s actually a male omega is a good thing, not something an angry stranger might snap over. Karma purrs and scents Nagisa as he massages Nagisa’s pecks and pets his nipples. 

Nagisa’s chest heaves as the touch lights his body up. He squirms a bit, grinding against Karma’s thigh. Nagisa parts his legs and the motion makes his skirt ride up higher and higher. Karma spares an eager hand to get it under Nagisa’s skirt. He strokes his fingers over Nagisa’s panties, coaxing Nagisa to spread his legs wider as his body heats up. Karma presses down, rubbing the outside of Nagisa’s pussy over his panties with three fingers. Nagisa gets wet as Karma plays with his chest and under his skirt while tenderly kissing his neck. 

When Karma feels the dampness through Nagisa’s underwear, he slips his hand inside. He slides his fingers along the folds, getting them wet. He nips at Nagisa’s ear with a low growl, making Nagisa shiver, then presses a finger inside. Nagisa’s so relaxed that the slide is easy. Nagisa angles his hips down onto Karma’s finger, clenching around it. Ever since the first time Karma got his fingers in Nagisa, he’s been insistent on doing it often. Every day, if possible. While Nagisa rarely initiates, he loves it too. Especially with how good Karma’s gotten at masturbating for Nagisa. Or finger-banging him. Whatever Karma decides to call it at any given time. 

Karma massages Nagisa’s insides with one finger before adding a second. He spreads his two fingers to stretch Nagisa out slowly, then lets him relax with a few agonizingly slow pumps. Only when Nagisa’s dripping onto Karma’s palm does he add a third finger. 

“Karma, Karma… ” Nagisa moans.

Nagisa squirms as Karma finger-fucks him, whimpering and panting. Karma hugs Nagisa from behind, his chest to Nagisa’s back. Karma’s erection is pressed to Nagisa’s lower back, throbbing for him. Nagisa felt Karma get hard plenty of times by now, yet he’s always so gentle about it. Karma’s so violent and dominating during jobs but with Nagisa - Nagisa is special. He knows he’s special. 

Nagisa swoons, loving the patience Karma has on reserve just for him. He wants Karma to feel how special he is too. Nagisa arches his back to grind his ass against Karma’s erection. Not just squirming that so happens to stimulate his alpha, but intentional. 

Karma moans, his fingers stuttering at the friction. Karma keeps his fingers stuffed into Nagisa but lets go of his hip to open the front of his pants with a jittery hand. Karma frees his erection against Nagisa’s back. This time, Nagisa does squirm accidentally on Karma’s fingers, biting his lip at the eager rush of heat between them. Karma changes the angle just enough to slip his cock between Nagisa’s legs. Nagisa’s chest heaves as he feels it glides along the outside of his pussy and watches with big eyes as the tip pokes between his legs. It’s weird to see something there but it’s okay because it’s Karma. Nagisa trembles as he grinds his pussy against Karma’s cock for the first time. They’ve gotten off together so many times but they’ve never fucked. Nagisa’s only ever felt the outline of Karma’s cock all over his body and imagined what it might be like to go all the way. He sways, suddenly dizzy and overwhelmed from the thought of Karma shoving his cock inside and claiming him. Nagisa pants faster and faster, his chest heaving. An unusual burst of scent pours from Nagisa along with a rush of slick. 

“Nagisa-!” Karma grits his teeth to not bite his best friend. 

His cock pulses with precum as what’s happening hits both of them. Nagisa’s going into heat. Karma fingered Nagisa into a heat. 

Nagisa wasn’t Karma’s omega. Nagisa was Karma’s best friend who was an omega. An omega that Karma couldn’t lie to himself about not wanting. It was one of those things where they were both pretty certain they wanted to be together forever but were too young and too afraid of making a mess of things by giving voice to it. Regardless of how they labeled their relationship, Nagisa, more panicked than he had ever been on his mother’s worst nights, made Karma rabid. 

He ran through the colorful district, knocking over people too drunk to get out of his way and weaving through traffic. 

As Karma approached, he looked down every alley he passed. 

“I’m almost there,” Karma reassured Nagisa again and again. “Almost. Where are you?”

“Karma,” the mousey squeak didn’t just come through the phone. 

Karma whipped his head towards the nearest alley and saw Nagisa crouched down. His head was peeking out no more than a meter above the ground. His eyes were bigger and rounder than Karma had ever seen them.

Karma pocketed his phone and rushed into the alley. He threw himself on the ground to scoop Nagisa into his arms, jeans tearing on the asphalt from the speed. Operating on instinct, Karma noticed two scents simultaneously. The acidic smell of Nagisa’s fear and the sharp tang of blood. 

“Are you okay?” 

Karma checked Nagisa over for injuries. The sight of blood on Nagisa’s hands made him dizzy. His little Nagisa. Karma wanted to kill someone over it. 

“Ah… I… I…” 

Nagisa lifted a trembling and sinfully cold hand to point at what he couldn’t explain over the phone. Behind Karma in a slump on the other side of the alley was a man. A trail of dark, coagulating blood matted his hair and streaked down the side of his face, visible only when the headlights of a car passed by. 

“I didn’t mean to,” Nagisa whispers to Karma again. 

Karma only clutched Nagisa tighter, wanting to stop his trembling. He held Nagisa to his side like a frightened child would hold a plushie and slowly approached. He figured the immediate danger was over, based on Nagisa’s behavior. Karma examined the scene further. With the next flash of headlights, he saw a bloody brick on the ground at the man's feet. Then, he took Nagisa’s hands once again to examine them more closely. Blood from the act covered Nagisa’s skin and seeped into the creases but, more importantly, there was caked blood and hair beneath Nagisa’s fingernails. Although, even if it hadn’t been an act done in self-defense, Karma can’t pretend he would have done anything differently that night. 

Karma nearly deflated entirely as he exhaled. His shoulders slumped as he rested his forehead on the back of Nagisa’s hands. 

“I am so glad you called me.” 

Like frying an egg, there was no reverting what became of Karma’s mind in that alley. Only one thing was in perfect focus. He needed to be strong for Nagisa. He could have his turn at a meltdown later. 

Above him, Nagisa sobbed softly and Karma hoped there would be some relief for him in that. 

“I… I tried to get away… but he… he wouldn’t stop and…” 

Karma let go of Nagisa’s hands to hug him. In Karma’s eyes - Nagisa was allowed to kill for far less reason than this. 

“It was self-defense…” Nagisa continued to insist miserably, wiping his nose on Karma’s shoulder. 

“But… but he showed me a badge and… I don’t… I don’t know what to do…” 

Nagisa’s fear burst inside Karma as a blinding flash of rage. He squeezed Nagisa tighter. Every part of him rejected what could come next if they didn’t take matters into their own hands. 

“I’m not letting anyone take you away for this. Not for even one second, understand?” 

Karma didn’t know how the cops would spin this story or if Nagisa could win such a case. He wouldn’t leave it to chance. 

Karma let Nagisa go only to drag the body deeper into the alley and the two of them hatched a plan to hide what they could and skip town. Summer nights were always rainy as the heat of day and the cool of night crashed together to crack open the sky. The blood was washed from the alley that night while Karma slashed three lines into the chest of the corpse. 

Karma helped Nagisa sneak back into his house and the two of them agreed to keep up an act of normalcy while they prepared for the inevitable. Karma gathered up all of the money he could  - shaking down snobby classmates, stealing from vending machines, and anything else he could get away with. 

The news reported the dead officer. His tearful wife and children appeared on TV, and the rest of the force pledged to find the killer. Karma hoped they would fall for the red herring of three slashes he left on the body but they wouldn’t count on that being enough.

Nagisa prepared to be ‘caught’. Since there was a struggle, Karma and Nagisa bet on the possibility of some of Nagisa’s hair or skin being found on the body. A fake positive pregnancy test in his trash and a suicide note are the final pieces of evidence they leave behind. 

Even if Nagisa was never linked back to the scene, it was worth it to have the excuse to leave. If Nagisa was linked to the scene, then hopefully the pregnancy test and Nagisa’s letter would be enough to make the police more interested in protecting their fallen officer’s reputation than investigating the pregnancy test itself and searching for Nagisa’s body. At least their corruption might make them stumble enough to give Karma and Nagisa a good head start. 

Using Karma’s cash, the two of them disappeared before the end of the year. The cash wouldn’t link their train tickets back to them and they counted on the chaos of Tokyo to hide them. They shared their first kiss on the train as it sped off into the night. A little, chaste moment that they don’t acknowledge for a long time. 

“Karma…” Nagisa whimpers, spreading his legs. He rocks against Karma’s still fingers. 

“I want you - it’s always been you…” 

Karma groans. He doesn’t need to be convinced. For him, it’s always been Nagisa too. He pulls out his fingers to guide his cock inside. Nagisa cries out from the stretch but he’s hot and soft and unbelievably soaked. Karma grips Nagisa’s hips tightly and forces himself to go slow until Nagisa’s fully seated. At first, Nagisa’s limp in Karma’s lap like a scruffed kitten, his pussy throbbing around Karma’s cock. Slowly, Nagisa starts by rocking his hips, grinding on Karma’s cock. When Nagisa moves, Karma’s hips jump up to meet him, forcing a yelp out of Nagisa. 

“Again. Karma, please , I need more-"

Before Nagisa can finish, Karma cuts him off with another thrust. They soon find their rhythm together with Nagisa bouncing on Karma’s cock. Karma tries to hold on but in a few minutes, he feels himself getting close. Everything from Nagisa’s body to his scent, to his voice, their connection is too much. Karma doesn’t want to not be enough for Nagisa. He reaches down to rub Nagisa’s clit while fucking him. With that, he’s able to get Nagisa to orgasm in time. Nagisa’s needy omega moans and pheromones are more than enough for Karma. With a deep, guttural moan, he comes inside, even knotting them together. Karma knows he shouldn’t have done that, but it doesn’t feel wrong when Nagisa’s mewling in his lap. 

“Oh, I, oohhh …” Nagisa is wide-eyed and breathless. His hands hover over his stomach as Karma’s cum is steadily pumped into him. 

Karma rests his forehead on Nagisa’s shoulder, shuddering and panting through the most deeply satisfying orgasm of his life. 

Before Karma finishes, Nagisa’s already grinding on his knot, his heat relentless. Needing to give Nagisa what he wants, Karma sucks a deep hickey into his shoulder while rubbing out another orgasm for his best friend. Entranced, Karma watches as Nagisa cums on his knot a second time, drenching it. 

When Karma’s knot goes down enough for him to pull out, he flips Nagisa over onto his back. Karma pushes off Nagisa’s bra to expose his flushed body and can’t resist stroking himself a few times at the sight. Nagisa watches the motion of Karma’s hand, more shameless than usual from being in heat. Nagisa wraps his legs around Karma’s hips, cum leaking out of his pussy. Karma pants at the sight and has to force himself to stop jerking off to Nagisa. Instead, he practically pounces on Nagisa, thrusting inside in one smooth motion. Nagisa cries out again as his body eagerly takes him. Karma grips the outsides of Nagisa’s thighs, his fingers digging into the soft skin. He doesn’t wait to start pounding Nagisa into the bed. Karma’s head spins at the sight of his cock sliding in and out of Nagisa’s body. Karma straightens for a better view and changes his grip on Nagisa’s thighs to push them up higher, spreading him further under the yellow motel lights. 

He bends Nagisa’s knees up by his chest and thrusts in at a steady pace. Karma stares shamelessly at Nagisa’s bleary expression. Nagisa’s overheated face radiates bliss, his eyes unfocused and his lips parted. Karma just can’t get enough of it and being the one to fuck Nagisa into this state makes him whimper softly, trying once again not to finish too soon. 

It’s not long before Nagisa’s scrambling for Karma’s shoulders to pull him down. Karma is powerless to resist when Nagisa wants to hold him close. He lets go of Nagisa’s legs in favor of hugging his shoulders and slotting their lips together. Karma groans into the kiss as Nagisa’s blunt nails clutch at his shoulder blades. He slides their lips together as Nagisa’s tongue traces the bottom of Karma’s teeth.

It feels like a dream to be with Nagisa like this. Karma’s first and only real friend in the world. Karma would do anything for Nagisa and helping him through his heat is more of a reward than a service, even when he can’t claim him. Karma greedily swallows down his reward, more than ready to make love to his best friend all night long. 

The second kill had been Karma’s fault. It was easy to be no one in Tokyo, but living there was even more expensive than Osaka. The city was full of alpha gangs and, at first, Karma thought getting in good with one of them would be the key to supporting them both. 

It turned out that being in a gang didn’t suit Karma. Maybe it was the hazing, the degradation, the orders, or the way they talked about Nagisa’s smell clinging to Karma… Whatever the reason, what made Karma snap was less noble than Nagisa’s case. 

Karma didn’t ask Nagisa for help turning the latest corpse into pieces little enough to fatten up stray dogs and cats, but Nagisa did have the good idea to pawn the alpha’s watch and rings. 

The third time they killed was planned. 

After Karma and Nagisa slipped away to a different part of Tokyo, one of Karma’s former gang members found them. Karma had been planning to kill her too, prepared to do much more than hide bodies to keep his life with Nagisa, but the alpha quickly stopped him and explained that she wanted to hire him for a job. She offered Karma and Nagisa more money for one job than either of them had ever seen and… and, well, it wasn’t exactly a hard choice. 

This guy was alive long enough to beg for his life. At that moment, Karma looked back at Nagisa only once. Nagisa’s eyes were cold and distant, showing the faintest flicker of disgust directed at their prey. There was no sign that he was going to tell Karma to stop. Karma had shuddered at that look and didn’t hesitate to cut the alpha’s throat. As the blood drowned the alpha and poured down his front Karma thought to himself Nagisa didn’t care for this man to live, so Karma might as well kill him. The thought released pressure on Karma’s mind. He felt relaxed as he chopped up that body and slept well that night. 

After getting rid of that body, when Nagisa was showering off the blood from having helped Karma, Karma knocked on the bathroom door. Nagisa was confused since that had never happened before. At first, he was worried that a loose end had caught up to them. Then Karma’s low voice came through, perfectly calm and steady. 

“Can I come in?”

Nagisa’s breath hitched at the suggestion. They’ve always kind of known without words that they were together but their relationship hadn’t budged. From being kids on the playground to sharing lunch periods, to Karma holding Nagisa as he cried through writing his fake suicide note, to the kiss on the train to Tokyo as they ran away together… They never called one another anything other than best friend but Nagisa knew why Karma was asking to come in. He couldn’t not know. 

Nagisa swallowed and took a deep breath. He wanted it too and if Karma was ready to take that next step then Nagisa was willing to take it with him. 

“Yes. You can come in.”

The door opened, letting in a bit of cold air to accompany the chill of anticipation. From beyond the curtain, Karma’s clothes thudded to the floor. Nagisa watched with wide eyes and weakened knees as the curtain slid aside and Karma stepped in. 

The first thing Nagisa did was glance down. He couldn’t help it. 

Nagisa pressed his lips together as his eyes flickered back up to Karma’s face. Though it didn’t make any sense, Karma felt taller like this. He didn’t know if he was supposed to say anything or what he could say. 

Karma didn’t pay any mind to Nagisa’s wandering eyes and he stepped closer to join Nagisa beneath the stream of water. There were speckles of dried blood on Karma’s cheeks and a developing bruise on his abdomen from when the struggling alpha kicked him. Nagisa’s gaze focused on the blood and he raised a wet hand to rub the gore away with his thumb. 

“Nagisa,” Karma sighed with open relief at the touch. 

Karma brought his hands up to hold Nagisa’s naked waist. Nagisa’s heart hammered in his chest but he kept himself distracted by cleaning Karma’s face diligently. Karma’s eyes closed as he leaned into the touch. Without being watched, Nagisa admired the shape of Karma’s lips. He traces a finger down to caress Karma’s bottom lip, drawing out a low groan. 

Karma’s familiar scent filled the steamy shower. Growing up, they would scent each other, and Nagisa simply thought of Karma’s scent as Karma. With this intimacy between them, Nagisa’s body also clung to the alpha scent. Nagisa flushed faintly as warmth pooled in his lower abdomen and trickled between his legs. He watched Karma take a slow, deep breath. Nagisa stayed still as Karma leaned into his building omega scent. When their lips met, Nagisa knew there was never really a wall between them at all. They were never separated by anything more than a shower curtain. 

Karma hummed into the kiss and let his hands roam around Nagisa’s torso. Nagisa’s eyes fluttered shut as he leaned into the touch, craving more contact. Karma must have felt the same because he pulled Nagisa into his chest as he deepened the kiss. Karma’s growing erection bumped into Nagisa’s stomach, drawing out a gasp as slick leaked down his thighs. 

Nagisa blushed deeper, embarrassed by his reaction, but Karma kept him held close. Karma’s tongue traces Nagisa’s lip and his embarrassment was lost in the kiss. 

Nagisa had no idea how long they spent kissing but even as his lips grew swollen and tingly he didn't get tired of it. Karma broke the kiss first, eliciting a soft whine from Nagisa. But Karma was far from done with him. Karma trailed firm kisses down the side of Nagisa’s neck, making him moan. Kissing down Nagisa’s chest was his final warning before Karma dropped to his knees to kiss just beneath Nagisa’s navel. 

Nagisa’s eyes flew open as he squeaked from embarrassment. He didn’t think Karma was going to go for that so soon. Nagisa covered his face with both hands but he didn’t push Karma away. Karma’s hands tightened insistently on Nagisa’s hips, keeping them in place as he tucked his nose into the crease of Nagisa’s thigh. 

Karma took a deep breath of Nagisa’s omega scent then rolled his tongue out to lick the slick off the outside of Nagisa’s pussy. Nagisa’s body throbbed in response and only leaked faster. 

Nagisa whimpered softly, he couldn’t help but watch despite being so embarrassed. He wanted to see that Karma liked it. 

Since it was clear Nagisa wasn’t going anywhere, Karma let go of his hips and used both thumbs to part the outside so he could easily drag his tongue directly along the wet folds. Nagisa’s breath hitched as soft, short moans spilled out. His embarrassment ebbed away as he adjusted to the sight of Karma’s head between his legs. 

If the porn he’d seen was any indication, Nagisa’s clit was embarrassingly small for an omega guy, but Karma didn’t seem to mind. The bridge of Karma’s nose found it first, rubbing the sensitive nub and making Nagisa truly squirm, trying to angle for a bit more of that. Karma noticed and licked up to it, giving his dripping hole a break to wrap his lips around Nagisa’s clit to suck it. 

Nagisa’s moans grew louder as Karma sucked and then swirled with his tongue. He spared one hand to jerk himself off while he ate Nagisa out. Nagisa watched the frantic motion of Karma’s hand, drool pooling under his tongue and rolling down his chin with water from the shower. Any lingering shame melted away and ran down the drain as Nagisa got closer to the edge. He rocked his hips into Karma’s eager tongue. He leaned back against the shower tiles for support as he finished, reaching orgasm and gushing all over Karma’s tongue while he lapped it up. Soon after, Karma finished, shooting thick spurts of cum along the shower floor. Though it was washed away by water nearly instantly, there were way more pulses that made Karma’s cock bob on its own than Nagisa thought there would be. 

Nagisa slowly caught his breath, the cold tiles against his back returned his senses to him. Karma got up from the floor, rubbing his knee while looking a little dazed from it all. 

It was not the last time they tried something like that. 

At the end of Nagisa’s heat, he wakes up without Karma by his side. Before he can truly be upset, the handle to the motel jiggles and Karma lets himself in with a shopping bag. On the table, he sets out a convenience store sandwich, a bottle of tea, and a packet of morning-after pills without a receipt. Nagisa blinks slowly, his mind catching up to what he’s seeing. It makes sense to take them, just to be sure. After all, they’re both a little too young for Nagisa to get pregnant… in addition to the whole killing-for-money thing. 

“…. Is this offensive?” Karma asks, shifting awkwardly on his feet when Nagisa just stares. “I’ll marry you anyway. We can get married right now.”

Nagisa covers his mouth as he snorts. What a terrible way to propose. 

“It isn’t offensive. Bring it here.” Nagisa says, his voice horse as he pushes himself up. 

Karma brings over the tea and pills. Nagisa gives the dosage instructions a glance before taking them with the tea. 

“Karma?”

“Yeah?” 

“I love you too.”

They’re wearing scent patches from the same pack - brightly colored shapes stuck to their necks and wrists like a middle school girl's diary. They’re matching as the scent of their growing arousal threatens to give them away. 

The pink, translucent crop top Nagisa is wearing may as well be made of tissue paper. Karma tears straight through it, exposing the bright red bralette. 

“Karma,” Nagisa means to chastise him but his tone comes out needy. 

Karma roughly gropes Nagisa’s chest as he buries his face in it.  Karma’s drool drips down into the center of the bra as he sucks and bites a bold mark over Nagisa’s heart. He kisses the mark and Nagisa practically melts. He really does have the best alpha in the world. 

Karma whirls Nagisa around to bend him over the sink, making Nagisa yelp. Karma reaches up Nagisa’s skirt to tear a hole in his neon stockings so he can push the crotch of Nagisa’s panties aside. Karma presses two fingers into Nagisa’s and scissors him a few times, the wet sound bouncing around the walls which only turns Nagisa on more. 

Instead of fingering Nagisa to an orgasm or two, Karma removes his fingers to grasp Nagisa’s hips. He jerks Nagisa back while thrusting in, slamming straight into the hilt. Karma’s right about Nagisa being wet enough. 

Nagisa yelps out a moan at the stretch but it feels so good. He quickly covers his mouth to muffle himself, hardly able to keep it together. Karma never treats him like this and yet Nagisa’s only thought is to spread his legs and try to goad Karma into doing it again. 

Before Nagisa can decide this is a bad idea, Karma’s drawing back halfway to pound into him again. 

Nagisa mewls as Karma fucks him, his pigtails bouncing with every thrust. Karma snatches Nagisa’s wrist to pin it behind his back. 

“Karma! Don’t-!” Nagia cries out again as Karma hits a particularly good spot. 

High-pitched, breathy whines pour out of Nagisa. He can’t control his whimpers any more than he can control the slick running down his thighs. Karma mercilessly fucks both of them out of Nagisa who only raises his hips to try to get Karma’s cock just a bit deeper. 

“No one’s coming, Nagisa. Just think about it. This will be the perfect place. We’ll choke him to death and no one will come check on him as he struggles. Then we’ll drag his body out the back - call him a drunk friend if anyone even bothers to ask.”

Karma’s fingers caress the side of Nagisa’s neck and gently press into his thundering pulse. 

“I can’t wait to kill someone where I fucked you. It’ll be a new first for us.”

“Karma,” Nagisa chastises Karma. “Pay attention to me.”

Nagisa moans brokenly into the sink, his knees jerking as he orgasms, squirting onto the concrete floor. He cries out as Karma keeps fucking him a bit longer, forcing Nagisa to swallow air and hiccup as it nearly becomes too much. 

Finally, Karma finishes, giving Nagisa the warm satisfaction of feeling his alpha’s cock throb as it pumps cum into Nagisa until it overflows and pools at his feet. 

Nagisa keeps gasping for breath, overheated and still hiccuping, slumped against the sink. 

Karma pulls out as he’s catching his breath. Cum pours out of Nagisa and to the floor, making him flush deeply. 

“Don’t worry about it. They’ve got a drain in the middle of the bathroom, right?” 

Karma’s back to being tender as he peels Nagisa off the sink. Nagisa thinks that’s no excuse but it’s too late for him to argue. He drapes his arms over Karma’s shoulders to snuggle into his neck while Karma takes on the task of scooping cum out of Nagisa’s pussy with his fingers and cleaning up his thighs with a damp paper towel. He adjusts Nagisa’s panties and pats his skirt back into place. The torn stockings are mostly hidden by the skirt but there’s nothing for the mesh shirt, leaving Nagisa in just a bra.

“Come on, Nagisa, let’s party.” Karma whispers. 

He sways them a few times like they’re slow dancing to the club music in the bathroom until Nagisa smiles, his head cool enough for him to nod. 

“Yeah, let’s party.”

They still have a job to do. 

They return to the dancefloor with Karma wrapped around Nagisa like a jacket. They stay around the edges of the crowd, moving together while keeping their eyes out for their target. Karma grinds on Nagisa and Nagisa gasps, his heart skipping a beat as he feels the wetness in his underwear. His own arousal, yes, but without a doubt some of Karma’s cum from earlier that they missed. 

They ‘dance’ together until they finally spot their target. The alpha goes from the front entrance directly to the bar to down a few shots of something that looks radioactive. Karma groans as Nagisa steps out of his arms for the sake of the plan. A few steps away from Karma and he’s already vanished into the crowd. 

Nagisa tugs on his pigtails to make sure they’re perky then approaches the target. It’s easy to lure him to the dance floor with a little hair-twirling and fake-drunken laughing. Nagisa’s got a hickey on his chest from Karma but no mating marks. With the outfit that’s only gotten worse since he arrived, the target sees Nagisa as an easy lay . 

The target pins Nagisa to the inside of the bathroom door. He gropes Nagisa’s chest - squeezing too rough, and sniffs his patched-up neck. Though his smell repulses Nagisa. 

Nagisa keeps his eyes open as the target mouths at his neck and grinds his hips against Nagisa’s. Nagisa watches as Karma’s feet touch the concrete floor and he creeps out of the bathroom stall. Karma’s cheap pleather jacket is rolled up like a rope and wound around his hands. He twists it one more time as he approaches. Karma’s eyes are focused and dark, meeting Nagisa’s gaze as he prowls closer. He looks at Nagisa with the intent to kill while the target’s hands move up Nagisa’s skirt, finding the torn opening in his stockings.

“Little slut , aren’t you?” The target moans. 

A heated breath passes through Nagisa’s lips. For half a second, perhaps their target is able to believe Nagisa likes his dirty talk. He moves his head from Nagisa’s neck and without meeting Nagisa’s eyes, looks down to drunkenly fumble open the front of his pants. Nagisa whines softly as Karma reaches around the target from behind and yanks him back with the makeshift rope around his neck. 

The man chokes and struggles, trying to twist away. This only helps Karma twist the jacket more tightly, increasing the pressure on the target’s windpipe from bruising to crushing. The target reaches back blindly for any part of Karma while he watches Nagisa with bulging eyes. 

Nagisa stays exactly where he was left for a moment, leaning back against the bathroom door with his skirt hiked up and his legs slightly parted as Karma muscles their target to the ground. Karma catches Nagisa’s eyes over the target’s shoulder and for a few heartbeats, he stares too. There’s an unmistakable hunger in his eyes as Nagisa watches him choke the struggle out of a man. Unable to breathe, he’s much less noisy than Nagisa was when he got fucked by Karma earlier. With renewed fervor, Karma forces the target to lay face-down on the dirty bathroom floor as his struggles get weaker and weaker until soon, he stops. Even after he’s gone motionless, Karma continues to wring the alpha’s neck. Karma’s on the target’s back, having pinned him down. He pants not from the effort of the fight but the rush of it all. 

Nagisa finally pushes off the bathroom door to approach. He crouches down next to Karma and he backs off so Nagisa can check the target’s pulse to make sure he didn’t just pass out. Nagisa sighs in relief to find that he’s dead. 

Karma keeps staring at Nagisa, his chest still heaving with desperate breaths as Nagisa gets close enough to smell if it weren’t for the patches. 

“… I want to fuck you so bad right now,” Karma whispers, his voice hoarse. 

“Then we shouldn’t have killed him in a public space.” Nagisa points out. He stands, placing his hands on his hips. 

Karma swallows hard and grits his teeth as he holds himself back. He gets up and hauls the fresh corpse off the floor. Nagisa helps arrange the body over Karma’s shoulders to make it look at least a little convincing that the man just passed out drunk. They have to hurry before rigor mortis sets in. They bring the body out of the bathroom and drag him along the edge of the dancefloor towards one of the exits. Predictably, no one notices a thing out of place. 

No one on the dancefloor, that is.

The owner of the club hires them next. 

Abductions are less pricey than killing but, Karma and Nagisa won’t turn down the job. 

“Relax, I don’t want to get you two in trouble,” the club owner drawls. “I had heard about a pair of new, unusual assassins in town. I didn’t expect you in my club so quickly.”

“So, this is the infamous killer omega, huh?” The alpha who is hiring them tilts his head as he regards Nagisa. 

“He’s cute too. Pretty eyes - even got him in extra small, hm?”

Nagisa crosses his arms as he’s checked out. The alpha turns to Karma whose eyes are dark. 

“I’m amazed - really. Y’know omegas are typically so sensitive about dirty work. How’d you train him?” He asks Karma with sincere excitement. “Or was he born wrong?”

Karma’s eyes narrow, his hackles raised. 

“Ah, I guess it doesn’t matter. How much for him?” The owner presses. 

“He isn’t for sale,” Karma grits out between his teeth. 

“Really?” The owner leans in, bending at the waist for a closer look at Nagisa as he circles him. 

“It doesn’t look like you mated him.”

The owner straightens upright and finally addresses Nagisa with a smile. 

“How about it, beautiful? Promise I’ll take good care of you.”

“Are you hiring us or not?” Nagisa asks, his voice carefully measured

The owner only brightens at hearing Nagisa speak for the first time. 

“I am, I am. After I saw what quick work the two of you made of that nobody - Ah, not that I’m threatening either of you as being a witness - not at all. Though perhaps I should install some cameras in the bathroom.”

Karma’s got that dark look in his eyes. Nagisa knows he wants to kill this man. He suppresses a shudder. 

“Who’s our target?” Nagisa asks. 

The owner produces a photo from his sleeve. 

“The daughter of one of my competitors. A regular loser who hasn’t learned properly from her daddy what the hierarchy is. That sort of thing. Bring her to the alley behind the club and we’ll take it from there. As long as she’s got all her parts, you get your money.”

It sounds like an easy job so Nagisa’s suspicious. Perhaps this owner simply made something up to meet them and open up a relationship with them. Either way, he saw them kill in his club, and he won’t be so easy to get rid of. 

“We should finish the job and skip town,” Nagisa decides as he and Karma check into a nearby love hotel together. “I don’t know what his angle is and I don’t want to find out.”

“Probably,” Karma grumbles. 

As soon as they lock themselves in their room for the night, Nagisa peels off his scent-suppressing patches. Karma’s still standing near the door, rage steaming from him as he stares into the middle distance. Nagisa moves in close, fitting himself against Karma’s back. He peels off Karma’s scent patches to nuzzle his neck. Karma begins to relax, tilting his head so they can scent each other. 

“… That pig. I’m the only one who’s right for you.” Karma growls. 

“I know,” Nagisa whispers back. 

Nagisa purrs for Karma sympathetically. With gentle hands, he urges Karma to sit with him on the edge of the bed. Many of their plans involve other alphas objectifying and even touching Nagisa. The difference this time is that Karma doesn’t get to kill this one. Nagisa tucks Karma’s face into his neck. 

“How about we watch a movie?” He suggests. “We still haven’t gotten around to Skilsaw Exploitation.”

Karma sighs through his nose. 

“I guess so…” he mumbles. 

Eventually, they got hired to kill an alpha who didn’t live his life in the shadows. It was apparent that this target would be hard for Karma to catch in an alley or break into his apartment undetected. 

“What if I help?” Nagisa asked as Karma poured over his options. 

Nagisa helped in all their jobs, but only for the planning and getting rid of the evidence. He hadn’t killed anyone since that cop in the alley. Nagisa had been a wreck and that kill wasn’t cold-blooded like the ones Karma was doing. 

“I don’t want you to have to,” Karma said. 

“I was thinking I could just help get him alone.” Nagisa pressed. 

Nagisa brought up the idea of being a lure first and Karma hesitated. He couldn’t deny that could be just what they needed, but it was risky. He didn’t want an attack like the one in the alley to hurt Nagisa further. 

“Are you sure?” Karma asked. 

“I am,” Nagisa said with a resolve Karma hadn't expected. 

“As long as you’re nearby to help, I can do it.”

On Nagisa’s decision, they formed a plan to get their target alone. They watched him enough to discover he had a thing for blondes. 

That was the first time Nagisa let himself be touched by another man and he didn’t have any memory of it. He followed the man into the hotel room, was tossed onto the bed, and then helped Karma roll his body up in a tarp. The only emotion he can recall from the gap in his memory was the fear of his wig coming off too early. According to Karma, there was a struggle when he jumped into the room from the fire escape so Nagisa held the alpha in a headlock while Karma got on top of both of them and stabbed their target in the chest. Nagisa didn’t really believe Karma. Surely if there had been that much chaos it would’ve been seared in Nagisa’s memory.

Karma continued to do most of their killing but Nagisa seemed to be alright with helping. Maybe something in Nagisa’s brain fried that first night in the alley too because he hadn’t broken down once since that night. 

They spend two days watching the alpha that the club owner hired them to abduct. She’s a young woman, easily as tall and broad as Karma, so they’ll have to work together to bring her down. She's rich from organized crime so Nagisa can see why the club owner wouldn’t want to hire anyone from an established group to go after her.

They wait for their moment to strike. When the alpha disappears into an underground casino, they make their move by targeting her driver first. They have an hour to get control of the driver, take his clothes, and stuff his body into the trunk. They complete that phase of the plan in half the time.

Karma’s build is more similar to her driver than Nagisa's, so he fills that role while Nagisa hides in the trunk with the driver’s unconscious body. There’s a tab on the back of the seats that Nagisa can pull from the trunk so he’ll be able to come out when the time is right. They only need to fool the alpha woman for a little while.

She emerges from the casino and Karma plays it cool. Over the two days of watching her, Nagisa and Karma observed that she doesn’t talk with her driver much. She gives the order for the next location and Karma grunts just like the driver used to. He pulls away from the casino and drives to the location he and Nagisa picked out beforehand. Karma has to go to one of the main roads first, which isn’t suspicious, but soon makes an unusual turn. He can sense the alpha stiffen, questioning herself about whether or not this is an alternate route. Of course, Karma has no idea how to get to the actual location she asked for.

“ Hey ,”

Her suspicion has grown to a critical tipping point. Nagisa pulls on the tab and the seat next to the alpha flops down. The alpha is startled but is experienced enough to have a hand on her weapon. However, Nagisa still has the element of surprise. The car remains steady as Karma turns down an unpopulated road while Nagisa springs on their target. They know she favors a taser, which is risky, but Nagisa knows it’ll be in her right hand before he sees it. Nagisa entangles the alpha like a snake.

He’s slippery enough to maneuver behind her and get a plastic bag over her head. At the same time, he kicks the taser out of her hand. The alpha thrashes while she can, knocking Nagisa into the car door and ceiling, but she can’t shake him. Although Karma had never really fought back when Nagisa choked him, Nagisa still has a lot of practice suffocating someone of this size. When the alpha’s struggling fades, Nagisa knocks her in the temple with the butt of his hunting knife. Once she’s unconscious, Nagisa takes the bag off her head. He checks her pulse to make sure he hasn’t killed her then binds her wrists with zip-ties.

Karma drives them back towards the more populated parts of the city and straight to the alley of the club as requested. The club owner laughs when he sees them dropping the alpha’s body out of the back of her own car and pays them the rest of the cash he owes while blowing a kiss to Nagisa.

Six months into their new lives, Karma told Nagisa he wanted a tattoo.

“Oh? What did you want to get?” Nagisa asked.

The two of them were sitting in the park in broad daylight, eating crepes for breakfast like a normal couple.

“Snake scales. Right here.”

Karma pointed to his inner wrist on his left hand.

“What’s the significance of it?” Nagisa tilted his head, taking in the unmarked skin.

Karma smiled and leaned over to take a bite of Nagisa’s crepe.

“I have a thing for snakes. Also, my left hand because it’s my more important one.” He said.

“I didn’t know you liked snakes.”

When they were kids getting to know each other on the swingset Karma had told Nagisa his favorite animal was a tiger.

“It’s a recent development,” Karma admitted.

“ But I’m dead serious about it.”

“If that’s what you want.”

They finished their crepes and went to go find a tattoo artist that same day. If Karma was certain, then there was no reason to wait. Nagisa and Karma knew how short life could be. Karma’s always been good at seizing the moment and ever since running away to build this new life Nagisa’s taken on a similar perspective.

Karma didn’t want much, just a band four or five centimeters wide of gradient scales. The artist they found said they could get it done in one appointment. Nagisa sat at Karma’s side while the artist cleaned Karma’s skin and explained how to care for the tattoo once it was complete. Though Karma didn’t really need comfort for the pain, Nagisa placed a hand on his shoulder while the needle moved across his skin.

A few hours later it was over. Karma’s tattoo was covered and the two of them continued on with their day.

“It did hurt,” Karma admitted to Nagisa when they were alone. “But I liked it - it was exciting. Maybe I’ll get another some day.”

They spent the night in the same park they shared crepes in. Nagisa cuddled into Karma’s side for warmth as they peeked at the fresh tattoo under a yellow streetlight.

“Snakes make me think of you,” 

Karma whispered to Nagisa now that the opportunity for Nagisa to talk Karma out of it had long passed.

“Really?”

They kissed under the light and whispered to each other until dawn. That night, Nagisa wanted to get a matching tattoo of tiger stripes on his wrist, but he never voiced that desire. They were always careful to never leave permanent marks on Nagisa’s body that could interfere with their work. Karma could afford to hide his body for his role in their dynamic but Nagisa’s body was often on display. A tattoo, just like a claiming bite, would’ve been an unnecessary risk.

“Just a little bit will be fine, won’t it?” Karma pleads, kissing Nagisa’s hands. 

Karma remembers it all so clearly. Nagisa’s eyes were cold and distant as his hunting knife carved through the last target, spilling carnage onto the floor. At the time, Karma had snapped and begged for just a little bit while the man’s dying breaths gurgled at their feet, only to be harshly rejected with a shove. 

Karma’s been hard ever since. He even checked them into a love hotel with a nice bathtub. After he and Nagisa rinsed off, Nagisa looked surprised to see Karma so turned on. As if Karma hadn’t begged to fuck him over the corpse earlier. Karma reminded him as much, including how sexy Nagisa was when he sliced that guy open. As usual, Nagisa looked doubtful of Karma’s words though Karma doesn’t know why. Nagisa knows they kill people. Karma’s sure he does. 

“I guess it’s okay if it’s just a few seconds…”

Nagisa agrees to Karma’s latest desire, making Karma’s erection throb against Nagisa’s ass. Karma nods enthusiastically. 

Nagisa turns to face karma. He looks so cute as he opens himself up to take Karma’s cock. He trembles as he takes it to the base. 

Nagisa places his hands on Karma’s shoulders and leans in to kiss him. His warm lips are tender and loving against Karma’s. Slowly, Nagisa’s hands slide up to Karma’s neck. His fingers fit around it as the tip of his tongue brushes with Karma’s 

The kiss breaks and Nagisa looks into Karma's eyes

“I’ll kill you,” Nagisa says just for Karma. 

Karma’s vision blurs as he’s dunked underwater but he forces himself to keep his eyes open. Nagisa’s pretty hands are wrapped around Karma’s neck as he holds him underwater and Karma grips the sides of the bathtub. His heart pounds in his ears, all other sounds muffled to almost nothing. His abdomen tenses as Nagisa lifts himself up halfway before dropping back down. The friction of Nagisa’s muscles squeezing Karma as he rides him is intoxicating. 

Karma has only been capable of having rational thought in increments since Nagisa killed their last target and now Nagisa’s choking out the possibility of Karma thinking at all. With his heart racing, Karma’s lungs ache for air as though he’s swimming for his life. Karma’s lips part and his chest spasms, jerking beneath Nagisa. Nagisa’s thighs tighten on either side of Karma’s waist to keep from being bucked off and even more of his weight bears down on Karma.

Karma’s claws at the sides of the tub and one of his legs jerks involuntarily. His whole body is burning but his omega keeps riding him. Nagisa’s drowning him and making use of Karma’s cock while he does it. Karma feels like he’s about to die and it’s ecstasy. 

Karma can’t tell if it was really a few seconds or even longer when he’s finally allowed to come up for air. He’s sputtering and coughing as a loud, pained moan rips from his aching chest. Black encases his vision and his whole body shakes from a violent orgasm. He nearly falls back into the water but Nagisa catches him by his shoulders.

“Ah, Karma...”

Nagisa’s flushed as clings to Karma’s shoulders. He’s looking down at their laps, distorted by the water. Only then does Karma realize that he knotted Nagisa again. 

Karma’s head is tilted back as he pants for air. His cock throbs again, pulsing more thick cum into Nagisa.

“Sorry… I couldn’t help it…”

Karma’s voice is faint and hoarse as he explains himself.

“You were killing me.”

They spend two more days in that love hotel. They only leave for food and a few preparations to leave this town. 

Nagisa has plenty of time to finally finish the book that’s been on his ‘read eventually’ list. Meanwhile, Karma entertains himself by looking for the strangest porn he can find on the pay-per-view television and occasionally mouthing at some part of Nagisa’s exposed skin.

“I want a mark,” Karma says one lazy afternoon.

They’re sitting on the bed together naked, flipping through take-out menus to pick a spot for lunch after a quick round that was tame enough for Karma to remember to pull out before knotting. Nagisa gives Karma a pained look. Karma’s never asked for that before and Nagisa always assumed that they had a mutual understanding of the subject.

“Karma, we can’t …” 

Instinctively, Nagisa raises his hand to the scent gland on the side of his neck. He’s thought about Karma’s claiming bite many times. At the base level of his brain, he craves it. Karma is Nagisa’s alpha. He’s strong and he’s caring and he has gorgeous teeth that Nagisa’s dreamt of since puberty. It pains Nagisa to reject Karma. If they had any other life, he would agree and jump straight into Karma’s waiting arms.

Karma places a hand on Nagisa arm.

“No, I know not for you. Not now, I…”

Karma leans in to nuzzle Nagisa’s hair.

“I meant just for me. You can at least put a claiming bite on me, right?”

The turmoil inside Nagisa quiets. His hand falls from his neck to the crumpled sheets between them. He wasn’t expecting Karma to say that. There are omegas who go their whole lives being claimed without ever getting to claim an alpha back, but Nagisa doesn’t think there’s much of a precedent for the opposite. Plenty of alphas find mutual claiming romantic and plenty more alphas find being claimed humiliating. Asking to be claimed without expecting to give the omega a bite in return is not a very alpha request.

Social implications aside, Nagisa can’t think of a reason to refuse. He swallows.

“... Are you serious?.”

“Dead serious.”

Karma tosses the menus aside and pounces on Nagisa, locking their lips together. Nagisa wasn’t all that hungry anyway.

If Karma’s sure he wants this mark then life’s too short to deny him it. While Karma devours his lips, Nagisa hooks one leg around Karma’s hips and uses it to roll them, switching their positions. Karma grunts as his back hits the bed. His lips stay locked onto Nagisa’s the whole time. 

Nagisa knows Karma will grab his waist, so Nagisa intercepts Karma’s hands to pin them on either side of his head. Karma groans into Nagisa’s mouth as he rocks his hips. Karma’s getting hard between Nagisa’s legs.

Nagisa breaks the kiss to look down at Karma. He appraises the sight of Karma. His handsome face is dappled with sunlight from the window, his bright red hair is a mess, and his eyes are only human when he’s looking at Nagisa.

“If you want me to mark you then I’ll be the one fucking you.”

Karma smiles and nods in acceptance, his face flushed. 

“Okay. I love you.”

“I love you too.”

Nagisa reaches between his legs to grab Karma's cock. Karma moans as Nagisa’s fingers caress it, a drool of precum slipping down the side. Nagisa pumps the length a few times, feeling it throb and get hotter while Karma impatiently groans Nagisa’s name. 

Nagisa’s still loose from earlier and the scent of Karma’s arousal turns him on. He lines up Karma’s cock to get it inside. A purr rumbles in Nagisa’s chest as it fills him up again. Karma squirms in Nagisa’s hold but isn’t trying to throw him off. Nagisa takes Karma to the hilt, sitting comfortably on his cock. 

Karma and Nagisa groan together as Nagisa leans down to nuzzle Karma’s neck. He laces their fingers together and breathes in the scent deeply. Drool pools on Nagisa’s tongue. Rather than swallow it down he opens his mouth to drag the flat of his wet tongue over Karma’s scent glands. Just like Karma’s wrist, it’ll bear Nagisa’s mark. He sets his teeth against the skin. 

Karma trembles and moans under Nagisa in a new way. Against the backdrop of Karma submitting himself to being choked and pushed around, today’s submission is fresh. Nagisa basks in the anticipation. He scrapes his teeth and gently sucks on the unmarked skin a little longer, rocking his hips just enough to feel Karma’s cock. 

He kisses Karma’s neck and lifts his hips up to nearly the halfway point before dropping back down. He moans Karma’s name and does it again, his pace as lazy as the afternoon. Karma moves his hips with Nagisa but obediently keeps with the pace, not bucking. Nagisa loses track of time as their bodies move together against the sheets. All Nagisa knows is that the heat inside him is at a low simmer which rises so slowly he’s at the edge before he knows it.

“ Karma, ” Nagisa gasps as a final warning. “I’m going to mark you.”

“Yes, yes, c’mon, Nagisa.” Karma pants.

Baring his teeth sends a thrill through Nagisa. For a moment, he feels like a snake. Like the ruthless predator Karma so lovingly compares him to. Nagisa surges forward to bite Karma’s scent gland.

Karma’s moan is guttural as Nagisa’s jaw clamps around his neck. Karma’s blood is in Nagisa’s mouth - his bite more vicious than necessary - but it tastes right. Karma squirms beneath him like prey but Nagisa holds on tight. It’s no surprise when Karma knots Nagisa this time - endorphins rushing between them. Nagisa’s lashes flutter and he cums as he sucks the deep scar into Karma’s neck.

Soon, Karma stops squirming. His only movement is the frantic pounding of his chest, his short breaths fluttering Nagisa’s hair. Nagisa listens to it just a bit longer before unlocking his jaw. 

The first thing he sees is Karma’s fresh blood swelling over the bite mark and Nagisa licks the remains of it from his lips. He looks at Karma’s face. Karma’s breathing is slowly calming so he isn’t hyperventilating anymore. His pupils are dilated and his eyes are cloudy.

“Don’t pass out on me,” Nagisa whispers.

Karma blinks and his eyes start to focus on Nagisa again.

“I wouldn’t do that when we’re locked. Promise.” He whispers back.

Nagisa scoffs. As though anyone chooses when to pass out - typical Karma.

“How’s it look?” Karma asks.

Nagisa looks at the fresh mark once more. He releases their shared white-knuckle grip to tenderly caress the bite.

“It looks good,” Nagisa says. 

He doesn't have the words to describe how much he likes it. Karma’s eyes flicker to the blood on Nagisa’s fingers. Nagisa raises his hand so it’s right in front of Karma’s face, letting him see it more clearly. Karma’s nostrils flare.

“It felt good. It felt amazing.” Karma says.

Before Nagisa can wipe his hand on the sheets, Karma surges forward. He catches Nagisa’s wrist and sucks his fingers clean.

“You have to try it someday."

Nagisa smiles, his heart fluttering anew as he watches Karma nuzzle his palm. He remembers the thrill of going down the slide with Karma as children. Since it was dangerous, it was against the rules to go down side-by-side as they did. They bounced off each other the whole way down and even bumped heads and they laughed the whole time. When he thinks of that, Nagisa feels as though he could have fallen in love with Karma that day.

“I will,” he promises.
