Crossing the Line Together

“So fearless….”

“You didn’t know I was fearless to begin with?”

No.

If anything, I know that better than anyone.

Instead of giving that obvious answer, Jeongyun pulled Seha in and swallowed his lips whole.

Kissing had become as natural as breathing now.

“Mm….”

When Jeongyun carefully rubbed their tongues together, Seha let out a soft, aching sound.

Perhaps because he had almost no experience, Seha was extremely sensitive to physical contact.

Whenever the kiss deepened even slightly, he would start panting and twisting his waist, and having to witness those reactions made Jeongyun feel as if his limits were being tested every single time—despite Seha having no such intention.

Their body heat rose warmly.

Jeongyun pushed Seha down so he lay flat, then naturally climbed on top and began seriously exploring his mouth.

When he traced the roof of Seha’s mouth with the tip of his tongue, Seha immediately moaned and wrapped both arms tightly around Jeongyun’s neck.

Normally, he acted all mature, like some dependable older brother, but when they exchanged touches, he always became more clingy.

It seemed the anxiety that came from being inexperienced made him rely on Jeongyun.

And honestly, that drove Jeongyun completely insane.

“Breathe.”

“Haah… hng….”

When Seha’s breathing began to grow strained, Jeongyun finally released the tongue he had been relentlessly sucking.

While Seha obediently caught his breath as told, Jeongyun pressed a light kiss beneath his chin, then buried his lips into Seha’s neck and began to lick and bite the soft skin.

Despite claiming he’d done plenty of hard labor, Seha’s skin was soft—like that of a pampered young master raised in a greenhouse.

Judging by his skin alone, he looked like someone who’d lived a life of constant care.

It was completely different from his hands, which bore faint calluses.

“It tickles, mm….”

As Jeongyun kept licking his neck, Seha shrugged his shoulders and let out a small giggle.

When Jeongyun had first used his tongue to pleasure him, Seha had freaked out, asking if it wasn’t gross.

But now, as if he’d grown used to it, he didn’t shy away and even moaned.

The realization that he was the one who had tamed Jin Seha to this extent made Jeongyun’s arousal swell rapidly.

Normally, he would have stopped around here.

If he went any further, he might get too excited to control himself.

Because their relationship had come together through such difficulty, Jeongyun wanted to approach this slowly and carefully.

Since Seha had no experience in this area, he wanted to give him time to adjust.

But today, stopping wasn’t easy.

Though he didn’t show it, afraid it might feel like pressure, Jeongyun’s patience had reached its limit after having his desires forcibly cut short again and again.

“W-wait… ah…!”

When Jeongyun’s hand slipped under Seha’s T-shirt and caressed his flat chest, Seha’s body trembled.

Jeongyun had touched him over his clothes before, but this was the first time he’d explored his bare chest like this.

Suddenly feeling every nerve sharpen, Seha tightly grabbed Jeongyun’s arm.

“Ah….”

Sensing the grip, Jeongyun barely managed to stop moving and lifted his head.

He had almost stripped Seha right there and pressed their bodies together.

Jeongyun looked down at Seha, who lay beneath him, breathing hard with a tense expression.

He seemed a little startled, but not uncomfortable.

“Jin Seha….”

Jeongyun slowly called his name.

His voice was much lower than usual, and it almost felt like heat shimmered through it.

Seha swallowed, and Jeongyun spoke.

“Do you want to have s*x?”

Jeongyun could have chosen a more romantic phrase, but he didn’t.

He didn’t want Seha to get swept up in the mood and agree without thinking.

At least the first time, Seha needed to know exactly what he was doing, and what he was allowing.

Jeongyun didn’t want Seha to wake up the next morning frightened or regretful.

He didn’t want this moment to be clouded by fear.

Everything Jeongyun had endured so desperately to avoid crossing the line had been for this—so Seha could think carefully and decide for himself.

After blinking a few times, Seha opened his mouth with a trembling voice.

“Do you… want to, young master?”

“Hey, don’t call me ‘young master’ at a moment like this!”

Jeongyun pressed a hand to his forehead, and Seha let out a small laugh.

That was the first time Jeongyun realized the word “young master” could sound erotic.

Either way, the tension eased a little, and Seha continued.

“I know you’ve been holding back because of me.”

“…I wasn’t holding back. It’s just common sense. I don’t have a hobby of forcing myself on someone who doesn’t want it.”

“Still… if you’d pushed me a little, I probably would’ve gone along with it.”

“I didn’t want to do that….”

“Yeah. That’s why I’m grateful.”

Seha knew there had been plenty of chances.

He might be inexperienced, but he wasn’t a child.

He couldn’t possibly miss the clear signals that came every time their tongues tangled and their bodies pressed together.

He’d just pretended not to notice because he was scared and hesitant.

It wasn’t fear of s*x itself.

He was more afraid of something else.

What if, after sleeping with another man, Cha Jeongyun’s feelings changed?

What if he cooled off?

What if, like waking from a fantasy, he suddenly wanted to undo this relationship?

That was what truly scared Seha.

It was the first time he realized just how afraid he was of relationships.

And how much more he loved Jeongyun than he’d thought.

“If I say I don’t want to… you won’t do it tonight either?”

As he gently cupped Jeongyun’s cheek, Seha asked.

He was provoking him with his actions while asking if he wouldn’t do it, and even he found his own shamelessness absurd.

He tried scolding himself—telling himself not to act so disgustingly pure at his age—but the fear wouldn’t fade easily.

Without knowing what was going through Jin Seha’s head, Jeongyun nodded readily.

“Yeah. I won’t.”

“…What if we do have s*x, and it’s not good?”

“You think it’ll feel bad?”

“No, not me. You, young master.”

Jeongyun frowned slightly at the unexpected question, then quickly snapped back, sounding offended by the misunderstanding.

“Jin Seha, do you know how many times a day I imagine having s*x with you?”

“W-what?”

“If you knew how badly I want to hold you, you wouldn’t say something like that.”

“Ah….”

“No, I mean—so, um…. I’m not trying to pressure you.”

Seha had said something so absurd that Jeongyun ended up being far too honest.

He’d deliberately avoided saying things like how hard it was to hold back, afraid Seha might feel pressured, but this was just too much.

“What I mean is… I’m worried you might dislike it or regret it. That’s all. That won’t happen to me, so don’t worry about useless things.”

Seha pressed his lips together.

Cha Jeongyun was always like this.

Whenever Seha worried and hesitated, he reassured him with simple, blunt words.

It was that very attitude—the one that made Seha fall in love with him, abandoning every reason he shouldn’t.

Gently pulling Jeongyun’s cheek closer, Seha said,

“Then let’s do it. s*x.”

“…You’re serious?”

“If you’re not scared, do you think I would be?”

As he looked into Jeongyun’s eyes, which darkened instantly at those words of full consent, Seha decided to willingly accept the flames pouring down on him.

“Ah, please, s-stop….”

It hadn’t even been that long since he gave permission, yet Seha’s plea spilled out like a moan.

No wonder—Cha Jeongyun had been thrusting his fingers into Seha while relentlessly sucking on his chest.

He brushed his tongue over the stiff, pink tip, then sucked again insistently.

At the same time, a third finger slipped inside Seha’s slickened entrance, stretching him open.

On top of that, Seha had already climaxed once by Jeongyun’s hand.

His entire body felt like it was melting, but sharp stimulation kept crashing down on his chest and below, leaving him unable to think straight.

“Does it hurt?”

“Ghh…! Don’t ask while biting my chest…!”

At the same time, Jeongyun rotated the three fingers filling him tightly inside.

Seha’s waist jerked upward on its own, his vision flashing white as he trembled with his head thrown back.

When the fingers first went in, the foreign sensation had been so overwhelming he’d thought he’d never adjust.

But as Jeongyun continued to stimulate him, licking all over his body, strange sensations slowly traveled up his spine.

Whenever Jeongyun pressed somewhere deep inside, his toes curled and moans spilled out without permission.

To think that hole could feel pleasure too—it was hard to believe, even as it was happening.

“So. Does it hurt?”

Jeongyun asked again.

Only then did his tongue finally release Seha’s chest and slide down along the faint line between his pecs, wetting his dry stomach.

Seha inhaled sharply and shook his head.

“No. It doesn’t hurt…. So please, that’s enough… stop with your hand….”

In the end, Seha was the one who clung to him first.

If this continued, he felt like he’d pass out before they even went all the way.

Jeongyun stopped all movement and straightened up, quietly looking down at Seha.

Without realizing it, Seha shrank back slightly.

Jeongyun’s gaze felt oppressive.

It was like raw sensation was stripping his entire body bare.

Fear and faint anticipation filled him at the same time.

He was scared of how intense the pleasure would be if he gave himself over completely—but he also desperately wanted to feel it.

“If it hurts too much, or you hate it… say it.”

“…….”

“I’ll stop… no matter what.”

Jeongyun spoke slowly, biting out each word as if suppressing himself.

It was obvious how much he was enduring through sheer willpower.

Seha felt his fear gradually fade, replaced by anticipation.

Even in a moment like this, hearing him say he’d stop if Seha didn’t want it made him want to entrust everything to him and gasp beneath him.

Before his head could think, Seha’s mouth opened.

“Okay, then hurry up… hold me.”

Jeongyun had reached his limit too.
