IDSEGI Chapter 69

Chapter 69

The bats clinging close to the ceiling swooped toward them, releasing high-intensity ultrasonic waves at the three.

If they had been exposed directly, it could have damaged their hearing or even caused tissue damage. But Yoon Geon’s Esper ability was water-based. In other words, he could slow and absorb the speed of ultrasonic waves through water, rendering the attack meaningless.

Before the wall of tightly compressed water, the ultrasonic assault was useless. If their offensive power had been reduced to zero—what about his side?

This was where the true value of an S-class Esper shone.

Yoon Geon unleashed a massive torrent upon the bats. It wasn’t ordinary water—it was a colossal weapon, compressed to a force sharper than a blade and heavier than steel rebar.

The bats were instantly and gruesomely sliced in half, their bodies raining down in heaps. There were so many of them that the ground was entirely carpeted, leaving no space to step.

With a flick of his fingers, a wave surged up from the center and split into two. It shoved the corpses aside, clearing a path through the middle.

The wall that had been shielding Yeoul soon dispersed into the air. Yoon Geon had been right—it was over quickly. An entire swarm of monsters had been taken down in one strike.

Yeoul was reminded once again of how incredible the Esper he had worked with really was.

“Wow… Hyung, that was amazing.”

Hearing the heartfelt praise, a faint smile tugged at Yoon Geon’s lips.

“What’s so amazing? Any Zone 1 Esper could do that much.”

Ihan grumbled in an attempt to undermine him, though even he was secretly impressed. Yoon Geon’s ability wasn’t just strong—his control was exceptional.

‘Guess he hasn’t been slacking on training.’

It annoyed him, but at the same time, it was reassuring. They needed every bit of power they could get right now.

Still, to unofficial SSS-class Esper Yoo Ihan, even this wasn’t much compared to himself. Unable to receive Guiding, he was conserving his strength, but to him, these monsters were nothing more than dirt under his nails.

‘Compared to me, he’s nothing, Yeoul!’

He wanted to shout it, but even he didn’t want to stoop to being that petty. Instead, he just burned inside, glaring at Yoon Geon with hostile eyes.

‘Look at that twitching smirk. Damn, I should’ve killed him when I had the chance.’

Ihan’s mood darkened even further.

After passing the mountain of corpses, the three decided to take a short break.

“Tired? Do your legs hurt? Want me to give you a massage?”

Ihan fussed over Yeoul, massaging his calves—though for someone showing concern, his touch was rather suggestive. Yeoul shoved him away with his palm.

“You’ve been carrying me the whole time. Why would my legs hurt?”

Yeoul glanced down at Ihan’s legs.

‘He’s been carrying me nonstop, but… is he really fine?’

Looking at his sturdy, muscular calves, Yeoul decided there was probably nothing to worry about. But when his gaze drifted to Ihan’s thighs, he flinched and quickly looked up at him.

“Hm? What is it, Yeoul?”

“You… you…!”

Why the hell are you standing like that?!

Ihan’s left thigh was noticeably bulging. They hadn’t even done anything, so why…?

Ihan blinked innocently at him. Yeoul, lips parting in disbelief, sneaked a glance at Yoon Geon.

Thankfully, it seemed Yoon Geon hadn’t noticed. Luckily, Ihan was sitting outside the range of the flashlight, so it wasn’t obvious—but it could be discovered at any moment. Acting as if nature was calling, Yeoul suddenly shot to his feet.

“I-Ihan, I’m going to the bathroom. Come with me— it’s scary.”

“Huh? Yeah, sure.”

Yeoul dragged Ihan deeper into the cave. Once they had put enough distance between themselves and Yoon Geon, Yeoul stopped abruptly and shoved Ihan against the wall.

“You… you… what is this?”

Ihan just kept smiling innocently.

“What’s what?”

When he dragged out the end of his sentence, Yeoul’s cheeks flushed bright red and he glanced downward.

“I mean… down there! Why is it… standing?”

If something had happened, maybe he could understand, but nothing had happened at all. What on earth was Yoo Ihan aroused by? Yeoul had no way of knowing.

Ihan looped an arm around Yeoul’s neck and leaned his solid weight against him slightly.

“Because I’m turned on.”

“By what, exactly?”

“By you, of course.”

I’m always turned on by you. The quiet, low voice made Yeoul flinch. Ihan pulled him close and subtly rubbed his leg against Yeoul’s groin.

“Hhhn… you, what is this…!”

“Not allowed?”

“Of course it’s not!”

“Why? Because Yoon Geon’s here?”

Did he even need to ask? Yeoul had no desire to do anything like this in front of his hyung. In fact, he didn’t want anyone at all to see him in that situation.

Even if the distance made it impossible to see, in a cave the sound could echo, and if they took too long it would be obvious. Yeoul struggled to get out of Ihan’s arms, but he couldn’t move an inch.

After a while of straining, he glared up at Ihan. Just how long had it even been like this? Ihan put on an exaggerated pout and whined.

“Yeoul, my penis really hurts. I’ve been hard for so long… it’s throbbing, I can’t walk.”

“Sing the national anthem or something to calm it down!”

His tone was sharp, but hearing him say it hurt made his resolve waver. After a moment of hesitation, seeing the tears in Ihan’s eyes, Yeoul lowered his head as if making up his mind.

“Fine. Then let go for a second.”

“Huh? You’ll do it?”

Yeoul shot him a quick glare, then slowly knelt down.

“Ye… Yeoul? What are you—”

Instead of answering, Yeoul gripped Ihan’s pants zipper with his teeth and pulled it down. Then he worked his tongue to unfasten the buckle and bit the waistband of his drawers to tug them down.

Watching this, Ihan swallowed hard. The sight, lit only by the beam of the flashlight, was so provocative that if he let his mind slip even for a second, he felt he might shove himself into Yeoul’s mouth and move like a madman.

While Ihan fought to gather the last of his self-control, Yeoul had already taken his penis into his mouth. His technique wasn’t polished, but he clearly knew where to focus.

His tongue lightly flicked the tip before he drew him in deep enough that his cheeks hollowed.

“Nngh, Yeoul…”

The wet sounds echoed faintly in the quiet cave. The texture of his tongue against the sensitive shaft only fanned the flames of arousal. Seeing Yeoul’s tearful eyes while he held him in his mouth made curses rise automatically in Ihan’s mind.

Shit, this is driving me crazy.

He fought the urge to push all the way in and release in his mouth.

Yeoul, for his part, felt like he was going insane. Ihan was always thick and large enough to make his jaw ache, and yet his body trembled with excitement.

Every change in Ihan’s expression as he licked or sucked sent a subtle, visual thrill through him. Heat pooled between his legs, and precum dampened his underwear. No matter how he tried to calm down, the desire only grew.

At that moment, Ihan suddenly grabbed Yeoul’s arm and hauled him up.

In the blink of an eye, Ihan yanked Yeoul’s pants down, pressed their penises together, and began stroking them in unison.

“Hhh… Ihan…”

Yeoul’s knees nearly gave out, but Ihan’s firm grip on his waist kept him steady. Ihan’s hand moved even faster now.

Yeoul’s shaft, trapped alongside Ihan’s thick length, rubbed incessantly until he couldn’t hold back and released. White fluid oozed from the tip, and Yeoul leaned his head against Ihan’s shoulder, breathing heavily.

“Haa… hhh…”

Ihan turned him around and braced his hands against the wall, sliding his own penis between Yeoul’s thighs.

“Ihan, you’re not—”

“I’m not going all the way here. Just… a little.”

He pressed Yeoul’s legs together and began thrusting rapidly. The friction didn’t give the same intense pleasure as penetration, but it was still enough to make him pant. The climax shot down to Yeoul’s toes as he came again.

When they finally returned after a long while, Yoon Geon didn’t question where they’d been. Yeoul rubbed his flushed cheeks with the back of his hand, sneaking glances at him. What had started as a way to cover Ihan’s arousal had ended up pulling him in as well—and he’d enjoyed it.

Yeoul was overcome with harsh self-loathing, but Yoon Geon suddenly held out a can of food.

“Eat. You must be hungry.”

Since he wasn’t saying anything else, it didn’t seem he’d noticed. Yeoul sighed in relief and took the can. But Ihan snatched it away, pulling out another from his bag.

“Eat this, Yeoul. It’s chicken soup. You like this, don’t you?”

It felt like he was showing off—“I know Yeoul better than you”—and Yoon Geon gave him a short snort. Then he handed Yeoul a spoon.

“Eat whatever. You need to fill up if you’re going to keep your strength up.”

He met Ihan’s glare directly and added,

“Especially since you’ll be Guiding me.”

Ihan’s eyes twisted into something fierce.
