Suyeol wakes up on Monday with an aching burn in his core. It could be attributed to the drinking he did last night, but he knows the feeling all too well to mistake it for the after effects of a binge. It's his heat, rearing its ugly head for yet another lonely week-long wank-off session.

He's too busy with work this month to allow that, however. Ryu Suyeol is no longer a carefree rookie who can call in sick; he actually needs to show up and get shit done, so he steels his resolve and drags himself out of bed. He trudges to the bathroom, ignoring the suddenly pleasant chafe of his silken pajama pants against his groin. How long has it been since he got laid? It can’t have been that long.

Rifling through his medicine cabinet, he finds what he's looking for: a bottle of heat suppressants. If taken on the first day of symptoms, his cycle should taper right off and he’ll be back to work by tomorrow, latest.

That is, if he manages to take them.

“Suyeollie…” The owner of the voice’s hands sneaks its way onto his shoulders and curious eyes peek over. “You're not really gonna take those, are you…?”

K’s voice is annoying as ever, but the warmth of another body pressed up against his own, even if it's just in his head, ignites the fire growing inside Suyeol. K’s body runs hot. How is that even possible?

“What do you mean- Of course I’m going to take it! I’m swamped with work, haven't you noticed? Or were you too busy lifting weights to see papers stacking up on everybody’s desks?”

K lets out a hum as his hands move under Suyeol’s arms, to hold him at chest level. The action makes them snuggle impossibly closer and Suyeol needs to push the other man away soon, before K makes him do something stupid. He doesn't push K away.

“What kind of superintendent lets his cycle take him away from work anyways?” Suyeol continues his grousing, since K seemed to be ignoring his previous statements. “Hey, you're supposed to be a hero, right? Heroes don't skimp out on their duties just because they don't want to take their medication.”

“Heroes don't have to take medication. They're stronger than that…” K’s voice drops to a sultry drawl. The fingers on his left hand splay out, digging pleasantly into Suyeol’s collar bone as he nuzzles into the taller man’s back. His other hand grips Suyeol’s wrist, sneakily pushing the pill canister back towards the open cabinet. The hot skin-on-skin contact almost feels like a branding. Fires in adjacent rooms threatening to burn their entire apartment down.

“I’ll…” K’s act dies down for a second as he pouts and thinks up what to say next. He changes tact. “I’ll die if you take them!”

A familiar sweet scent suddenly hits Suyeol’s nose. It’s heady and saccharine. It’s slick. Is K…? Is he…? Already?

“You’re not going die,” Suyeol says absentmindedly, K’s ministrations are making it harder for him to think straight, “Just let me take this so I can go to work.”

“I don’t wannaaaa…” If K wasn't grinding against Suyeol’s backside before, he’s definitely doing it now. He lets out another petulant whine. Suyeol can feel his warmth through the thin robe K wears to bed. “I’m going to die right now if we don’t get back to bed-”

“Shut up.” Suyeol swallows. He tries to pull his wrist away from K’s grip before the other man fully wears down his resolve, but the movement sets his alter off. K drops the sweet facade and immediately tries to wrestle the bottle away from Suyeol.

They end up tussling like children, pushing and shoving at each other, both refusing to back off. Suyeol just barely manages to redirect them back into the bedroom to avoid slipping and breaking his neck on the bathroom sink.

K throws an arm around Suyeol's neck from behind and wrestles the both of them onto the bed, Suyeol lying on top. K wraps his legs around the man’s torso to get him to stop squirming, and the familiarity of the pose throws Suyeol off guard.

K manages to pry the lid off the pill bottle and throws it across the room, small round capsules flying in its path. Suyeol curses.

“You asshole-” Pills forgotten in his rage, he focuses his full attention back to K. He’s just barely managed to brute force his way out of K’s chokehold when a hot flash hits his entire body, causing him to curl in on himself.

He feels the whine eke its way out of his throat before really hearing it. He can't hear anything over the sound of his own heavy breathing right now. He lets his body fall to his sheets, burrowing into his damp pillows.

Dizzy from the sensation, a vision flashes in his mind. A familiar smile, and a polite voice that sometimes forgot to conceal its alpha growl. A new addition to his squad who’d been looking at Suyeol with curious eyes ever since they kissed again all those months ago. Hui-gyeom.

“You should call her...” K gasps as another bout of full body shivers hits him. He's placated for now, sidling up to Suyeol like their previous fight never happened. “She could help. She’d want to h-”

“Shut up, idiot.” Suyeol grits out. “What kind of person would that make me? Use your brain for once.”

Suyeol lets out a shaky breath. He turns to look at the pills scattered across the floor and resigns himself to the insufferable week ahead of him.

That's how Suyeol finds himself texting his department that he’ll be off for the entirety of the week.

How he ended ass-up naked on his own bed, with four of K’s fingers inside of him, he's not entirely sure. He's got a good guess though.

“Feels good, doesn't it, Suyeol?” K grins at him, massaging in a motion that makes Suyeol forget how to speak. “It’s almost like I know exactly where your most sensitive spots are.”

We have the same body, dumbass. Suyeol huffs dismissively, bracing himself further against the nest of pillows K had helpfully made for them. K’s fingers are good, but he's not willing to admit that anytime soon.

“You're doing so well today, you know?” K takes a deep breath and leans in, leaving biting kisses on the curvature of Suyeol’s pale bottom. He uses his free hand to grab at Suyeol’s slick-coated inner thighs, dimpling the skin with his thumb. “You smell so good too…”

Before Suyeol can protest, K pulls his fingers out and replaces them with his tongue. Hot electricity shoots up Suyeol’s spine.

“Wh- Wait! Wait, wait,” He reaches out behind himself to push at K’s head, the sensation almost too much. K’s strong arms wrap around his midsection, locking both of them in place.

K’s licking inside of him with dedicated fervor, nose pressed right up against Suyeol, breathing in the heady smell of slick. Suyeol whimpers, wriggling in K’s grip once again.

“K. K.” Suyeol gasps out, body spasming erratically. K pushes a thumb in alongside his tongue, almost like he's scooping out slick from Suyeol’s cunt, trying to get as much of Suyeol inside his mouth as possible.

A high pitched whine is all the warning K gets before Suyeol comes. The hand in K’s hair tightens its hold, unintentionally tugging K closer.

K keeps going, lapping up every single drop. Suyeol groans. His face feels like it's going to melt off from embarrassment and heat. He finally musters up the energy to start pushing K’s head away again, whimpering from overstimulation.

“Stop- stop that,” He mumbles out, pawing at K’s forehead. “S’too much, you punk.”

When Suyeol’s thighs start shaking, K finally relents, leaving one last sloppy kiss to Suyeol’s backside. He loosens his grip on Suyeol, who immediately lets his lower half drop to the bed like a bag of rocks. His limbs feel heavy, the heated ache in his core only temporarily subsided.

Suyeol doesn't need to look at K to know the bastard’s grinning from ear to ear. He keeps his face buried in the crook of his arm as he waits for his breathing to steady.

K stretches languidly and lowers himself down against Suyeol’s back. He presses light kisses to Suyeol’s spine along the way, almost reverent in a capacity that Suyeol wouldn't have expected from the man. He doesn't have the energy to question it at the moment.

Once K reaches Suyeol’s neck, he lets out a contented hum. His arms curl around him, as he nuzzles into the taller man’s back just as before. His weight presses Suyeol into the bed, gentle pressure easing both of their nerves.

“See, that was nice, wasn’t it?” K leers with his signature grin. He sighs loudly and gets off the taller man, laying beside him instead. “Ah, I think I’m in love with you, Suyeollie.”

Suyeol huffs. “We're not done yet.”

“Hm?” K feigns innocence despite the knowing grin on his face. In a couple of seconds, Suyeol is on him, flipping over to tower over the shorter man.

K still has his stupid bathrobe on. Suyeol tugs at the strings until they loosen and open up. The smug bastard leans back even more, pretending to stretch by raising his arms behind his head, nonchalantly giving Suyeol more access to his body.

Pulling the layers open, Suyeol eyes flit around to take in every inch of his alter’s toned body. Of course he's not wearing underwear. K pretends to yawn as Suyeol pulls his robe fully off, leaving him in the nude. The bed sheets feel cool on his warmed skin.

Despite his unaffected act, K can't hide the way his eyes darken when Suyeol looks at his groin, already damp with slick. He shamelessly moves his thighs apart, an open invitation to Suyeol.

He’s been sopping wet from the start, so starting off with three fingers would've been too easy. Suyeol opts to ignore his cunt in favor of flicking his thumb over his beloved alter’s clit, making the man gasp, hips hopelessly stuttering upwards.

He does it again, and again until K’s thighs involuntarily close on Suyeol’s hand with a spasm, trying to stop the persistent abuse.

“Ah! St-stop that! You’re being too cruel!” K whimpers out between gasps, fists bunched up in the sheets. He grinds up against Suyeol’s trapped hand, impatient and needy.

“Should've thought of that before you stopped me from taking my pills, huh?” Suyeol graciously lets K hump his hand for a few more seconds before he starts prying the man’s legs back apart.

Suyeol would be lying if he said he didn't feel a thrum in his veins at getting K to moan and whine like a common omega whore.

“If I’m one, that makes you one too…” K breathes out, reading Suyeol’s mind.

Suyeol gives him another well-received flick before getting off the bed.

“Wait, where are you going?” K raises his head, wide-eyed.

“Calm down. I’m just grabbing something.” Suyeol replies, treading across the room to rifle through his closet.

It takes a while, but he finally comes back with something that makes K’s face flush.

A toy, in a particularly eye-catching shade of red. It’s the same shade as K’s biker jacket. The bulbous head glistens meanly, thanks to a tiny hole at the tip for dispensing lube. It’s fairly girthy, about the same width as Suyeol’s skinny forearm and a third of the length as well. The veiny length leads down to a sizable knot. At the end of it, there's tubing connected to a syringe full of lube.

Suyeol gives it a little test, lightly pressing down on the syringe. A cloudy bead of thick liquid oozes out from the tip, so viscous it takes a while to properly roll down the length of the plastic cock.

He notices K’s scent immediately turning liquid at the sight, arousal permeating every inch of the room.

“Whore.”

“Suyeol. Where did you get that.” K deadpans, ignoring the jab.

“This? Oh, I’ve had it for a while. I’ve been single for way too long, you know.” Suyeol blabbers as he clambers back onto the bed and pushes his way into the space between K’s legs.

K’s eyes follow the dildo, sharp as a knife. He's breathing heavily even though nothing’s happened yet. Suyeol chooses to ignore this.

He lifts K’s thighs and rests them atop his own, elevating the other man’s hips. He places the cock on top of K’s mound, angling the knot right up against his clit.

“Look at that,” Suyeol whispers innocently. “It reaches up to here.” He trails a finger up K’s belly, tracing the light smattering of coarse hairs leading up his navel. He stops and taps right where the dildo reaches. Half an inch above K’s belly button. K is being uncharacteristically quiet, stomach tensing as Suyeol starts to drag his finger back and forth across his skin.

A tiny bit of liquid leaks out of the tip. K’s breath hitches, watching it drop onto his abdomen. Suyeol grins as he presses his finger into the droplet and smears it, pressing it into K’s skin.

“Suyeol…” He breathes out in a deep, raspy whisper. “Please.”

Suyeol hums as he picks up the cock and rubs it against K’s entrance. K’s slick has been leaking onto the bed since Suyeol brought the dildo into play, dampening the sheets beneath them and making Suyeol’s thighs slippery. His hands are trembling a little, but he knows K is too gone to notice. He’s almost there too.

Suyeol finally pushes the head of the cock inside, mesmerized by the way K just opens up and takes it. His hips rise eagerly to take in even more than Suyeol is giving him. Suyeol hears K’s low moan over the sound of blood rushing in his ears, the quiet baritone of it sending a pleasant shiver down his body. Suyeol shifts his eyes up to sneak a glance at his alter.

Face tilted towards the ceiling, K’s no longer looking at Suyeol. He has an arm slung over his eyes, while his other hand entangles itself in the blankets of their nest. His mouth is open in a pretty little ‘O’ shape, pink lips glistening from his own drool.

Suyeol would take a picture of it if he could. He wants to. He settles for ingraining it into his memory as best he can, taking note of all the soft subtle shades of red K’s painted in.

He slowly pushes the rest of the length in, observing the hitches in K’s breathing every time he sinks an inch deeper. Once he’s bottomed out, K lets out a high pitched whine, feeling the knot pressed up against his entrance. Suyeol’s other hand is holding his hip, preventing further wriggling.

“Agh! Hah…” K cants his hips downwards as much as he can. His eyes are scrunched shut, refusing to look at Suyeol. “You’re so- you’re so meaaahn…” He sounds on the verge of tears, voice stuttering with every nudge of the knot against his entrance.

“So greedy,” Suyeol teases, grinding the knot back and forth against K, but refusing to let another inch go in. “Is this how you’d react to just anybody when you’re in heat? You’d let anybody off the street knot you right then and there?”

“N-no…” K pouts and shakes his head. “Just you.” He whines.

K’s body is radiating so much heat, Suyeol swears it’s warming the entire confines of their small bedroom. A forest fire and Suyeol wants to let it devour him whole.

He quickens the pace of his thrusts, causing the other man to moan even louder. K needily hooks his ankles together behind Suyeol’s back to pull him in closer.

“Su-suyeol, I’m close,” K gulps, urging him to go faster by digging his heels into Suyeol’s spine.

“Then come, jagiya.”

The pet name does something to him. K is suddenly coming so hard Suyeol sees stars. Suyeol manages to push in the knot with the help of K’s spasms, making the other man’s thighs quiver. K bears down on it, like the good boy he is, whining for all he's worth.

The apex of the knot stretches him so good, Suyeol feels full just looking at him. Once they're past it, it's almost like K’s hole is greedily sucking the rest of it in.

“Suyeol, the- the-” K’s reaching for something. Suyeol quickly remembers and pushes the plunger on the syringe.

“Ah.” K’s eyes roll back, as he whimpers and trembles in Suyeol’s lap. Suyeol keeps one hand on the plunger, and the other on K’s tummy, feeling for the bulge of the knot. With the knot and the come being released inside him, K feels impossibly full. It's hard to breathe. He feels like Suyeol could break him in half and he wouldn't mind.

“We’re gonna have pups together, Suyeollie,” K is breathless and smiling at him. It's a ridiculous suggestion but Suyeol feels his heart give way at the thought of knocking K up like that.

“If that were true, I wouldn't be able to wait for this to get bigger,” Suyeol rubs his hand over K’s belly again, slightly distended from the knot and the lube. K gives a pleased little wriggle in response, like a puppy getting a belly rub.

“And these as well,” Suyeol continues, reaching up to grab at K’s chest, massaging it and roughly pinching his nipple between his index finger and thumb. The pink nubs quickly sharpen under Suyeol’s ministrations, a contrast from the soft mounds underneath it. K gasps and shudders. Suyeol feels the knot get pulled in just a centimeter deeper and knows that K’s just came again.

He gently places K’s legs back onto the bed, reveling in the sweet noises K makes upon the shift in position. Suyeol gives him a couple pats on the thigh to get him to move onto his side, and K obediently obliges. He lays down behind K, making sure every inch of their skin is touching. His hands reach around to press gently on K’s core, as if he really were being impregnated. The thought makes both of them shiver but neither of them brings it up.

Like this, they could wait out their heat for at least a couple of hours before they'd need to get back up again. Suyeol can't think of anybody else he'd rather spend his time with.

Gyeong-tae gets to knock on the door a fifth time before Hui-gyeom decides enough is enough and keys in the passcode. No surprise, it's still her birthday.

“Eh? How did you know that?”

Jae-seon gives a knowing smirk. “You didn’t know? These two used to-”

“Sunbaenim, are you in here?” Hui-gyeom calls out as she swings open the door, ignoring her colleagues' antics.

The moment she steps through, she knows she has to leave. Pushing past Gyeong-tae and Jae-seon, she hurriedly runs back down the hallway with a muttered “You guys handle this.”

Gyeong-tae is confused, until he steps closer to the entrance and smells it. The entire apartment reeks of heat musk, sweet and intoxicating. It makes sense that an alpha like Hui-gyeom wouldn't have been able to stand it.

As an omega himself, the smell sends a rush right down his spine. He tamps down on it and uses his sleeve to cover his nose, blocking out the worst of it.

“Sunbae… I think maybe you should step out as well,” He gives Jae-seon a look. The man’s pupils are already dilated, but he understands and backs off, walking to the elevators to wait with Hui-gyeom.

Gyeong-tae walks deeper into his superior’s apartment, completely unfamiliar terrain to him. He can guess where the bedroom is, though. The scent seems to be emanating from a specific doorway.

“Sunbaenim… are you-” Gyeong-tae has to clear his throat as he calls out through the closed door. “Do you need any help? We were worried when you called in sick, so we brought, um, a fruit basket.”

It's true, he's cradling a fruit basket in one arm. It feels silly now, with the situation they're in.

He hears a soft groan coming from inside the room and steels his resolve. He has to check. What if Superintendent Ryu Suyeol had somehow gotten himself hurt in the throes of his heat?

“If you can't answer, I’m going to enter now, okay?” He gives a beat to allow Suyeol ample time to answer. He doesn't.

Gyeong-tae scrunches his eyes closed and turns the doorknob, pushing it open.

“Sir, are you okay?” He opens his eyes one by one, greeted with a debauched sight.

Suyeol is naked and passed out in a makeshift nest on his bed, hugging a pillow. There are sex toys scattered around him like a summoning circle. Gyeong-tae tries to not stare.

The older man’s chest is rising and falling in soft breaths, making Gyeong-tae release a sigh he didn't realize he was holding. At least the man’s alive. After the sudden ominous text in the office group chat earlier this morning, their entire department had been worried about him. Nobody thought it’d just be his heat cycle. Even Jae-seon had seemed surprised.

Gyeong-tae knows what it's like, battling a cycle without suppressants. He's surprised he found Suyeol alone and not with some alpha. There are services for that these days, and he wouldn’t begrudge his superior for turning to those kinds of things.

He nips back out to grab a bottle of water he saw on the dining table before gingerly padding back into the room. He's not sure what the protocol calls for in this situation. He places the bottle on the nightstand and pulls the sheets up around Suyeol, blanketing him, should one of their other colleagues decide to enter the room.

“K…” Suyeol lets out a little moan as the soft sheets envelop him, snuggling deeper into the nest.

Ah. That's when it hits Gyeong-tae. Ryu Suyeol’s not alone. A smile fights its way to Gyeong-tae’s face as he studies the gentle sleeping face of his coworker.

Two kindred souls in one body. To be honest, he’s a little jealous.
