Minjae is used to seeing Seeun all sweaty.

It's part of their job at this point- dancing hard, practicing said dancing. Heck, even singing while dancing!

Seeun makes eye contact with him through the mirrored wall, winking with both eyes and smirking as he uses the hem of his shirt to wipe his face, giving everyone a peek of his flat tummy shining with sweat.

And though the other members boo him for trying hard to look sexy- Minjae is amused by it. Liking when Seeun is overly confident- knowing he has the actual chops to back up the grandiosity.

Not unlike the bitch underneath him right now.

"Calm down already!" Minjae says, pinning the omega's arms to the bed.

"Ooh, big alpha leader telling the whiny omega what to do!" Seeun scoffs, looking to the side even if it's just the boring view of ransacked closets and drawers. He was the perpetrator of that mess. "What's next, you gotta be a macho man too?"

"J-just shut up." Minjae sighs, letting go of Seeun as he leans back, shifting his light weight so that Seeun's cock grinds onto his ass. "I'm trying to get into the mood?"

They're already one year into being idols, but it was still quite the herculean task to deal with heats- especially when it's just him, Hunter and Hyunwoo in the group- outnumbered by the amount of members who presented as omegas.

That doesn't even take into account the fact Hunter loves to bottom even as an alpha, which isn't all too bad since Junghoon, Yujun and Yechan love breeding him enough to break their heat without ingesting a knot.

Hyunwoo on the other hand, is as traditional as can be, helping the others out when Minjae is preoccupied with another omega. It's almost methodical and clinical whenever Hyunwoo knots, which is how Junmin, Sumin and Jinsik prefer it anyways.

Which leaves Minjae the only one capable of handling Seeun.

"Feels good?" Minjae says, grinding downwards again and watching Seeun convulse below him, feeling his dick slide between his ass cheeks. As a leader, he had to be flexible. Especially in occasions where none of the omegas are available to be knotted during Hyunwoo and Hunter's knots. "It's good for hyung."

Seeun laid there, refusing to meet Minjae in the eyes even when his body radiated magma- wanting nothing more than to be spread and pierced by the man on top of him.

But heats are always tricky- messing with the mind. For omegas like Yujun and Yechan, they become needier, whiny and tearful when their slick becomes uncontrollable, having to be taken care of and coddled by an alpha to avoid it lasting more days than needed.

Seeun, on the other hand, does a complete 360° in personality.

"Hyunwoo-hyung fucked you during his rut." Seeun whispered, trying to not sound insanely jealous as his hips respond to Minjae's gentle rocking, shivering when the tip of his leaking cock licks onto the leader's rim. "What kind of alpha let's that happen to him?"

Minjae doesn't respond, understanding that this to, is part of the process of bringing down Seeun's walls.

"What should we do then?" Minjae asks, his tone sultry as he leans back onto Seeun's dick, reaching behind him to give it a few pumps. "Want to fuck hyung as well? Show Hyunwoo how it's done?"

Seeun moans at those words, eyes hazy and heat-drunk as he looks up to the ceiling, convulsing as Minjae continues the slow, delicious torture on his dick.

He licks his lips when a particular grind makes Seeun whine.

"Or, you still want hyung's knot?" Minjae taps his dick onto Seeun's stomach, smearing some pre-cum knowing that the scent of it, of Minjae-hyung is irresistible to the younger.

And to show that he isn't cheekily taunting Seeun like how they always do- Minjae takes an embarrassingly long whiff of the air, smelling like raw sex and an overwhelmingly nauseous vanilla. Knowing Seeun's nest was completely soaked in his slick.

"I-I... Hyung?" Seeun's response is less aggressive now, becoming much more pliant.

"I know you smell it too." Minjae says, shifting his position as he lifts himself off of Seeun, watching his dick stand proud at full mast as he slots himself between Seeun's legs and eyeing the copious amount of slick there. "Our scents-"

Seeun sniffs, moaning when Minjae easily slips two fingers into his hole, making more of his wetness spill out onto the sheets. Once his fingers are sufficiently soaked, he touches himself for the first time tonight, relishing the slickness of his fist as Minjae's dick spits more pre-cum out, spreading his cinnamon scent onto the room.

"Shit-" Minjae curses after a particular stroke, feeling his knot beginning to inflate as he watches Seeun's hands roam over his naked body- as if bathing himself in their pheromones. "Hyung's reaching his limit- tell me, how do you want to-"

"Need-" Seeun leaves red lines on his own skin, almost as his breaking point. "Need hyung- but he," Seeun takes a breath, tears forming on his eyes. "He wants Yujunie-"

"Baby, no-" Minjae is quick to lay down on Seeun, trying his best to envelop the younger's long and lanky frame, embracing him as he puts their scent glands together. "Hyung was just helping Yujunie with his heat, is all."

"Liar." Seeun's tone was feral, but is restrained by Minjae's arms around him as he tries to lift off the bed- jealousy souring his scent. "Hyung's knot was in his mouth-"

"Only for a bit-" Minjae explains. Any other time, Seeun would have been completely supportive and involved with Yujun's heat- even helping him through it many times as he himself let's Yujun suck him off! "Hyung's here now- for Seeunie."

After a few more beats of Seeun struggling and Minjae reassuring him, the omega finally calms down.

"Hey," Minjae tries, still on top of Seeun as the younger finally looks at him, wet and shining from numerous bodily fluids. "Hyung's here."

Seeun nods, whispering for something as Minjae immediately indulges him, leaning down to kiss the omega.

Slowly, he lets off so that Seeun could reposition him, never pulling apart as his hands explored Minjae's body, tracing every plane of muscle in his back before he took a generous squeeze of the leader's butt, beginning to fill up now as he focused on some squats.

Minjae is moved to lay on his back- now having Seeun straddling him as slick trickles down his cock.

"Inside." Seeun whispers, lifting himself up as he directs Minjae's dick onto his leaking hole. "Want you inside me."

Minjae might not be used to seeing Seeun all sweaty.

Especially now, glowing from his heat, flushed pink and shining in sweat as he slowly takes Minjae inch by inch, only stopping when his stretched rim meets his knot.

"Hyung~" Seeun howls, low and lustful as Minjae takes a hold of his hips, other hand linking their fingers together tightly.

Minjae isn't particularly big down there, but there's still effort to be made when letting the knot slip as Seeun moans through every accompanying thrust Minjae makes, both of them exhaling when Seeun's ass finally hits Minjae's hips.

And with it came one of the many orgasms Seeun will have to break his heat, spurting cum all across Minjae's abs and reaching all the way to his neck, making the alpha chuckle as he licks a drop that lands on his lower lip.

It takes hours of different positions, and Minjae's hand wrapped around Seeun's cock, matching the pace of his hips before they finally empty his balls out, and with it left the younger's heat. It leaves their bodies sore and connected as Minjae's knot was snug inside the omega's ass.

"God, why are you always so difficult?" Minjae groans, throat dry as he gags on the smell of their aftermath- the haze of heats no longer warping reality. "It's like a pig's pen here."

"Yah, you should see when the rest of 05z is finished with Hunter." Seeun argues, groaning when he tries to move, bringing Minjae along with him. "I want water."

"Don't move-" Minjae yelps in pain when Seeun squeezes around his knot via pulling him forward with his movement. "Jesus- let's just ask one of the members to hand us a bottle."

"How am I gonna ask when I can't reach-" He makes another move, making Minjae grunt again before his fingers finally catches his phone, sending a quick text to the group chat. "There."

Half an hour passes by with them just laying there before someone knocks at their door.

"I'm leaving it here in front okay!" Yujun shouts from the outside. "There's some snacks too."

"Aish- bring it inside!" Minjae shouts, making Seeun flinch and cover his ears as the elder tries to move- belatedly remembering the vice grip Seeun has on him as the younger reacts in pain. "Shit-"

"We can stand up together if you really want to." Seeun offers.

"Okay." Minjae nods. "Lead the way then."

Seeun doesn't move after saying that, crossing his arms in front of him.

"You're so eager to get up now." Seeun puts on his best, whiny-omega-in-heat impression in an attempt to troll Minjae. "Is it because Yujun's the one bringing our food?"

Right now, he expects Minjae to volley back, like he usually does when they're on camera.

Instead, he feels Minjae's hand pound once on his back.

"Why-" Minjae gets cut off by a sob, making alert sirens ring in Seeun's head. "Why are you always so, difficult-"

"Hyung, it was a joke-"

He feels arms wrapping around his middle and pushing him to Minjae's front, the leader burying his forehead onto his shoulder blades.

"You already get special treatment from me-" Minjae's voice is shaky, followed by a sniffle. "I let you top when you need- we're not even mates and yet I've tried being exclusive when it comes to anal-"

Seeun feels his heart drop to his ass.

Maybe his body felt the gravity of the situation as Seeun moves and makes Minjae's knot slip out with ease as he flips around on the nest- ignoring the spike of pain on his shoulder as he faces the leader hiding his face.

"Hyung." Seeun tries, Minjae's words washing over him as he recognizes in multiple scenarios of the omegas whining in their heats about Minjae being too busy to fuck them. "Hyung, look at me."

It's only when Seeun takes a hold of Minjae's tear-stained and probably snot-riddled hands does the leader look him in the eyes.

"I'm not supposed to pick favorites-" Minjae whispers. "Everyone's counting on me- the company, even ATEEZ sunbaenims-"

"Whoa, hyung you're kind of overreacting." Seeun chuckles, trying to lighten the mood but is surprised when Minjae's finger pokes hard at his chest.

"No, you understand this!" Minjae's tears go from sad to angry. "How I lead you all reflects on everyone that came before me-" He takes a breath, and another, becoming quicker and quicker in between. "If I fail, then KQ didn't teach me properly- which means ATEEZ weren't good sunbaes- which means Minseok-hyung and my parents didn't-"

"Minjae, calm down!" Seeun cuts him off, surprised to see the alpha like this. He's seen it once- when they were trainees. "I mean, fuck- Hyung, follow my lead, okay?"

Minutes pass between them as Seeun guided Minjae's breathing, never letting go of their intertwined hands as the leader's head knocks onto Seeun's chest.

"You're not supposed to see that." Minjae whispers after a beat.

"Hyung-"

"I know." Minjae stops him from continuing. "It's a two-way street." He pulls away to hug Seeun properly, nuzzling into the warmth the younger radiated to comfort himself. "But still- I'm your leader-"

"Alpha." Seeun whispers. "You're a man too, aren't you?" He ponders for a bit before speaking again. "Should you be hugging another guy so tightly like this?"

He cheers in his head when Minjae snorts at that.

"Ah, I could never talk to you seriously." Minjae shakes his head, but doesn't pull away from Seeun.

"But wow..." Seeun gulps, unsure if he should bring it up when Minjae doesn't seem to want to talk about it. "A year in and you're thinking about mates already?"

Quiet envelops them again before Minjae replies.

"I always think ahead." Seeun rubs circles at his back, urging him on. "That way, I could lead you guys down a path."

Seeun nods, a sense of dread instilling in him when he thinks of the joke at the tip of his tongue.

Maybe it was because they've just had sex- or the fact Minjae mentioned the aspect of mating first-

Seeun can't imagine anyone but himself for Minjae to claim.

"I guess Junminjae becomes official in three years?" Seeun quips, ignoring the pang of jealousy those words ring inside of him. It was standard industry practice for the two eldest members to be mated.

Minjae looks up at him, searching something in Seeun's gaze before smirking. "Aigoo, you should do better to not be so jealous~"

Wanting the last laugh, Seeun lowers himself until his face is to Minjae's scent gland.

He prays for Sumin's blessing despite the older omega being alive.

"Fine then." Seeun runs his tongue across his teeth before biting down on Minjae's shoulder, causing the leader to yelp in a mixture of pain and shock.

"Yah! What are you doing-" Minjae tries to dislodge him, only urging Seeun to sink his teeth harder. "Oy, I'm going to punch you if you don't let go-"

Seeun pulls off at that, smiling when he sees the reddish-pink teeth marks decorating Minjae's neck before licking at it to sooth the pain.

"Mine." Seeun whispers, hiding the trill that travels up his spine from those words.

Morning comes as Minjae wakes up on Seeun's nest alone.

He opts to go back to sleep when he hears a ruckus outside their room, unable to ignore as he rubs at the soreness around his scent gland while standing up.

"Minjae-hyung is gonna kill me." Seeun's voice says from the living room as Yechan's boisterous laughter followed his words.

Everyone turns toward Minjae when he arrives.

Minjae watches Sumin flick Seeun's scent gland, surprised to see that both of them felt the sensation.

"Wah, I didn't think you had it in you." Sumin says as Junmin hooks an arm around Minjae, shaking him as the world falls silent around him.

There was a news report on their television, detailing a brand new discovery about omegas being able to claim alphas with their teeth as well-

"Holy shit." Minjae whispers, looking up at Seeun panicking at the irreversible consequences of his action before his eyes meet the leader's.

And though Minjae's still trying to process everything going on around him like the member's reactions, he can read Seeun's lips as the tall omega held his hands, vowing to do right by him and do his best to uphold the responsibility that comes with being mated with the leader.

"Okay." Minjae nods. He himself doesn't know if he sincerely believes in Seeun- not when he's such a headache to handle.

But what's a journey without a few bumps in the road?
