Ah… Sex without a condom was really a big deal.
“Should I run to the convenience store now? They sell them there, right?”
“They don’t have my size in Korea.”
Right. He’d mentioned ordering condoms from overseas.
“We don’t have lube either. And the lotion’s in Siwoon’s room.”
Why would you need that? Kim Sibaek had the thought for a fleeting second—only to realize the answer himself. …Yeah, it would be necessary. If it’s needed even when you’re with a woman, then between two men, it’s definitely essential…
While Kim Sibaek’s mind briefly blanked, Tae Woon offered an alternative.
“If it makes you uncomfortable not using a condom, you can top instead.”
“Uhh…”
Even though Tae Woon talked about sex constantly, Sibaek had always deliberately avoided visualizing anything concrete. After a brief moment of consideration, Kim Sibaek shook his head. He didn’t know the details, but he’d heard it hurt. There was no way he could ever hurt Tae Woon.
And if it was going to be painful regardless because they had no lubricant, then he’d rather be the one hurting. He was used to injuries from hunting monsters and crawling through battlefields, and he could heal himself anyway…
“It’s okay… you do it.”
For some reason, he got the strange feeling that Tae Woon’s eyes, half-hidden in the dark, had lit up.
“Hyung, hyung. We don’t have a condom.”
“Yeah, I heard.”
“Like, really really—we’re doing it raw, okay? It’s okay if I come inside you?”
“……I’d prefer if you pulled out before you finish.”
“I’ll try my best.”
Which basically meant he wasn’t even going to pretend to pull out. …Going raw was one thing, but why was he so excited about finishing inside? This world had seriously gone off the rails if it was letting teenagers get this horny and misguided.
While Kim Sibaek was silently cursing society, Tae Woon’s hand moved boldly between his thighs. Wherever those firm fingers touched, they left flushed streaks, threading tension into every inch of skin.
Tae Woon caught Sibaek’s reflexively twitching hips, held them steady, and pressed his thumb against the perineum as he gently stroked below. The unfamiliar sensation of being touched in a place he’d never really been aware of before made Kim Sibaek suck in a sharp breath. As the fingers parted the tightly closed, crumpled folds and teased the entrance, he was at a complete loss for words.
“Ugh, ah…”
It felt like he was burning up and ticklish all at once—his ass flinching and shying away involuntarily. The only thing all these sensations had in common was how utterly alien they were.
When a dry finger finally slipped inside, prying the wrinkles apart, the unfamiliarity intensified tenfold. Kim Sibaek covered his face with his hands, not out of embarrassment, but because… he genuinely didn’t know what to make of it. The feeling was just too weird.
It didn’t hurt, since it was only one finger, but the strange, foreign intrusion from below was deeply disorienting. So this was how they stretched things with fingers first, and once it was loosened enough, that’s when… insertion. Jesus.
Before he could even start getting used to the strangeness, Tae Woon began to move his finger. He rubbed the tight, clenching inner walls, curled his knuckle, and stirred deep inside. The sensation of something shifting inside his belly was uncomfortably vivid.
That itchy, indescribable feeling kept poking around under his navel, and Kim Sibaek couldn’t take it anymore.
When he sat up abruptly, Tae Woon flinched.
“Hyung, did it hurt? I tried to go slow… It was just one finger, but is it that bad? Does it hurt a lot?”
“Woon-ah.”
“Yeah?”
“Just put it in.”
Tae Woon blinked, repeating the words after a pause of two or three breaths.
“Huh?”
“There’s no lube, so fingering alone won’t be enough. Might as well just go for it.”
“Uh… but it’s probably going to hurt a lot, and it might even tear…”
“If it tears and bleeds, that can act as lube, right?”
“……”
“And I’ll just heal it afterward.”
Tae Woon went silent for a moment, then let out a muffled laugh. He leaned in and pressed a kiss to Kim Sibaek’s forehead.
“Sometimes, the way you throw yourself out there—makes it obvious I grew up under your wing.”
If anyone else had said that, it might’ve felt like an insult somehow, but coming from Tae Woon, it was just the plain truth. Still, Sibaek didn’t think he was being reckless. Given the lack of both condoms and lube, wasn’t this a logical decision?
Before he could dwell on it too deeply, Tae Woon tilted his head forward. Their lips met, and his tongue slid in. While Sibaek’s attention was consumed by the heat ravaging his mouth, Tae Woon gently pushed him back onto the bed. The teasing finger slipped out—and something far thicker and hotter rubbed against his entrance.
Tae Woon’s cock was pressing at his hole, trying to get inside. Realizing that, Sibaek’s heart pounded so hard it felt like it might crack his ribs. Reflexively, he grabbed onto Tae Woon’s forearm. A wave of tension surged up his spine, stiffening the back of his neck.
“Relax your hips. Just breathe, hyung.”
Kim Sibaek took a few steady breaths, nodded—and then realized it was too dark for Tae Woon to see. So he said it out loud instead.
“…Go ahead.”
The moment the words left his mouth, Tae Woon grabbed his ass and spread it open. His grip was so firm it left deep red marks blooming across pale skin, and through the forcibly pried-apart opening, the thick tip of his cock barely began to press in.
“Nngh…!”
Sibaek clenched his jaw tight, fighting back the scream that nearly tore out of his throat. His body wasn’t relaxed—hell, they hadn’t even done proper foreplay.
His entrance, which had barely taken in a single finger before, was still tight and dry no matter how much Tae Woon forced it open. The blunt head pressed in, shoving against the unyielding flesh, and pain flared so sharply through his hips it felt like his pelvis might crack. Tae Woon’s fingers dug in harder.
Trembling, Sibaek tried to will his body into relaxing, but it was an uphill battle. If this had been anyone else but Tae Woon, he would’ve shoved them off and ended things already.
Still, maybe the effort was paying off—he could feel something thick and heavy beginning to push deeper inside. He swallowed the scream clawing at his throat and asked, voice barely steady,
“D-Did it go in?”
“Phew… Hyung.”
Tae Woon’s breath rasped out between clenched teeth.
“Not even the head’s in yet.”
Fuck.
Sibaek squeezed his eyes shut. Darkness swirled behind his eyelids.
“L-Like a cat… If the head fits, the rest’ll—ugh—somehow follow…”
“Hyung. Cats are liquid. My cock isn’t.”
“Then… make it liquid…”
His brain was foggy and words just spilled out. Tae Woon let out a shaky breath and began to pull his hips back, as if reconsidering.
“There’s no lube, but I’ll run to the convenience store and grab something. If we keep going like this, you’re really going to get hurt.”
Now? Sibaek’s mind immediately filled in the scene: Tae Woon, half-naked, throwing on clothes, heading down to the first floor to grab supplies, while Sibaek lay here alone in this cooling room… waiting.
Just picturing it was enough to yank him straight out of the moment.
Besides, how was Tae Woon even supposed to go out with a hard-on like that? Gritting his teeth, Sibaek locked his legs around Tae Woon’s waist, stopping him just as the tip was about to slip free.
“I’ll deal with it. Just do what you want.”
He meant it as a firm, resolved answer—but Tae Woon’s breath hitched, growing even rougher.
“…The worst thing about you is when you say stuff like that without even realizing.”
“Huh?”
He didn’t get the chance to ask what that meant.
Tae Woon grabbed behind Sibaek’s right knee and lifted it, draping his leg over one shoulder. His thighs were spread wide before he could react. Then Tae Woon yanked him in close, pressing down with his full weight.
“Hnnngh! Agh!”
That unbearable tightness from before—it had all been because Tae Woon had been holding himself back. The moment he was told not to, he bore down without restraint, just like the night he left bite marks on Sibaek’s neck.
The entrance that Sibaek had thought was already stretched to its limit was forced to open even more, inch by brutal inch. It felt like being carved open with a blade. The pain was so real, so vivid, it overwhelmed everything.
His lip, already bruised, split open as he bit down hard to stop the scream. The sharp taste of blood spread across his tongue—and right then, Tae Woon leaned down and pulled him into a tight embrace.
“Don’t bite your lip. Bite my shoulder.”
Instinct kicked in.
Kim Sibaek buried his face in Tae Woon’s shoulder and wrapped his arms around the boy’s broad back. His scream never made it out—he clamped his teeth down into that shoulder, hard. And then it came—that sickening, searing pain that tore through his body like he was being split in two.
