Ah… sex without condoms was truly a problem.
“Should I go to the convenience store now, hyung? They sell them there, right?”
“There aren’t any domestic ones that fit the size.”
That was right. He had mentioned that he bought condoms from overseas.
“There’s no gel, either. I left the lotion in the room where Si-woon hyung is sleeping.”
The thought ‘Why would we need that?’ flashed through his mind for a moment, but Kim Si-baek soon realized the answer. …He would need it. It’s necessary when sleeping with a woman, but it must be essential for two men…
While Kim Si-baek’s mind went blank for a second, Tae-un suggested an alternative.
“If you’re uncomfortable not using a condom, you can be the one to penetrate.”
“Uuuuh…”
Even though Tae-un constantly talked about sex, Kim Si-baek had intentionally avoided imagining the concrete details of actually doing it. After thinking for a moment, Kim Si-baek shook his head. He didn’t know the specifics, but he had heard it was painful, and there was no way he would let Tae-un be in pain.
If everything would hurt anyway because there was no lubricant, it was better for him to be the one hurting. He was already accustomed to injuries from hunting magical beasts and rolling around on battlefields, and he could treat himself…
“It’s okay, you do it…”
For some reason, Kim Si-baek had the illusion that Tae-un’s eyes, buried in the darkness, sparkled.
“Hyung, hyung-hyung. There are no condoms.”
“Yeah, I heard you.”
“Is it really, really okay to do it raw? Is it okay if I cum inside you, hyung?”
“…If possible, I’d prefer it if you pulled out before ejaculating.”
“I’ll try.”
Those words meant he wouldn’t even pretend to pull out before ejaculating. …Setting aside the lack of condoms, why was he so excited about internal ejaculation? This world, which had guided a pubescent teenager’s sexual desire down the wrong path, was seriously broken.
Whether Kim Si-baek lamented the state of the world or not, Tae-un’s hand moved boldly between his thighs. Tension was etched into every reddish mark left by the firm fingertips on his skin.
Tae-un gripped his reflexively twitching pelvis and caressed him below, pressing the perineum with his thumb. Kim Si-baek gasped at the unfamiliar sensation touching an area he had never particularly been conscious of. He didn’t know how to describe this feeling of fingers nibbling at the entrance, parting the tightly closed folds.
“Ngh, ah…”
It felt like a mix of yearning and itchiness, and his buttocks seemed to twitch and avoid it instinctively. The one commonality was that all these sensations were incredibly foreign.
As a dry finger entered, pushing open the folds of the hole, the sense of foreignness deepened. Not knowing what to do, Kim Si-baek covered his face with his hands. Rather than being embarrassed, he truly just didn’t know. The feeling was too strange.
Since it was only one finger, it didn’t hurt, but the foreign body sensation felt from below was too unfamiliar. So, he would loosen the bottom with fingers, and once it was relaxed enough, the insertion… My god.
Before he could get used to the strangeness, Tae-un moved his finger. He poked around inside, rubbing the tight, stiff inner walls and bending his knuckles. The feeling of a finger moving inside his belly was too vivid.
The strange, ticklish sensation kept poking at the area below his navel, and Kim Si-baek could no longer bear it.
As he lifted his waist, Tae-un flinched.
“Hyung, did it hurt? I tried to move gently… I only put in one finger, what should I do? Does it hurt a lot?”
“Un-ah.”
“Yes?”
“Just put it in.”
Tae-un made the same sound after a couple of breaths.
“What?”
“Since there’s no gel, there’s a limit to how much you can loosen it with just fingers. In that case, I think it’s better to just do it.”
“Uh… then I think you’ll be in a lot of pain, hyung, and it’ll definitely tear…”
“If it tears and bleeds, wouldn’t that serve as a substitute for gel?”
“….”
“And I can just treat it when it’s all over.”
After a moment of silence, Tae-un let out a low laugh. Then, he kissed Kim Si-baek’s forehead.
“Seeing how you just go for it sometimes, I’m certain I grew up under your influence, hyung.”
If anyone else had said this, he would have felt like he was being insulted, but coming from Tae-un, it was naturally true. However, he didn’t think he was just ‘going for it.’ Wasn’t this a rational decision given the lack of condoms and gel?
Before he could delve deeper into his thoughts, Tae-un tilted his head. Their lips overlapped, and a tongue pushed inside. While his attention was focused on the heat stirring and sucking inside his mouth, Tae-un laid him back on the bed. The finger that had been troubling him below withdrew, and something incomparably hot and thick rubbed against the hole.
Tae-un’s genitals were tapping the entrance to enter him. Realizing this, his heart thundered as if it would break his ribs. Kim Si-baek reflexively gripped Tae-un’s forearm tightly. The sudden surge of tension made the back of his neck stiff.
“Relax your buttocks, stop being so tense, hyung.”
After taking a few deep breaths, Kim Si-baek nodded, then realized it wouldn’t be visible in the dark and spoke aloud.
“…You can do it.”
As if he had been waiting for that answer, Tae-un grabbed his buttocks and pried them apart. The glans entered tightly through the gap forced open by a grip strong enough to leave red handprints on the white skin.
“Hngh…”
Kim Si-baek bit his lip hard to stifle the scream that threatened to burst out. Far from being relaxed, his bottom had received hardly any foreplay.
The entrance, which had barely swallowed one finger, was terribly narrow and stiff, no matter how much it was pried open. Every time the blunt glans forced its way through the narrow space, a pain that felt like his pelvis was twisting echoed through his waist. The grip of Tae-un’s hands on his buttocks tightened further.
Trembling, Kim Si-baek struggled to relax the muscles below. If his partner hadn’t been Tae-un, he would have pushed him away and stopped long ago.
Still, perhaps because he had managed to relax, he felt something heavy entering his belly. Barely suppressing the scream that wanted to escape, Kim Si-baek asked.
“Did… did you put it all in?”
“Phew, hyung.”
Tae-un whispered with a voice that sounded like it was grinding through his teeth.
“Even the glans hasn’t gone in yet.”
My god.
Kim Si-baek closed his eyes tight. Everything went black.
“Like… like a cat that only needs its face to pass through, hngh… if you just put the front in, somehow, ngh, it’ll work…”
“Cats are liquid. My cock isn’t that soft.”
“Try making it soft…”
Since he was out of it, nonsensical gibberish came out on its own. Tae-un breathed heavily and slowly straightened his waist.
“There’s no gel, but I’ll go buy something at the convenience store. You’re really going to get hurt at this rate.”
Go to the convenience store now? For a moment, the subsequent sequence of events played out in Kim Si-baek’s mind. Tae-un, wearing nothing but a gown, would get dressed, go down to the convenience store on the first floor, and buy the items, and while he waited alone in the room, the air would cool down.
…It was a scene that brought a wave of reality-hit just by imagining it.
Besides, how could he manage that erect cock and go out? After clenching his teeth, Kim Si-baek wrapped his legs around Tae-un’s waist, just as the glans, which was barely hooked on the edge, was about to be withdrawn.
“I’ll endure it, so do whatever you want.”
It was an answer meant to be a firm decision, but for some reason, Tae-un’s breathing became significantly rougher.
“…The worst thing about you, hyung, is that you do this without intending to.”
“Huh?”
Before he could ask what that meant, the back of his right knee was grabbed. As one leg was hooked over Tae-un’s shoulder, his crotch was spread wide. Tae-un pulled the open thighs close and pressed down, adding his full body weight.
“Hngh! Ah!”
Kim Si-baek realized that the tight insertion up until now had been the result of Tae-un’s consideration in avoiding excessive attempts. As soon as the permission to do as he pleased was given, Tae-un pressed down mercilessly, just as he had when he left a mark on Kim Si-baek’s neck.
The area he thought had been stretched to its limit began to be forced open further. He felt like it would be better to have his flesh sliced with a knife. The pain of the bottom continuing to open precariously was too vivid.
To hold back the screams that surged up, his already wounded lips were torn by his upper teeth. As the metallic taste of blood spread through his mouth, Tae-un bent his waist and hugged him.
“Don’t bite your lip, bite my shoulder.”
Almost instinctively, Kim Si-baek buried his face in Tae-un’s shoulder and wrapped his arms around the broad back. The scream, unable to escape his lips, was chewed messily into Tae-un’s shoulder, and a terrible pain that felt like it was tearing raw flesh finally split him open from below.
