Good Night, Brother! - Chapter 4.7 (R19)

“That’s good, huh? That’s good.”

“Now that… That… heh…”

Eun Hyun could barely form coherent words, his voice faltering. A trickle of drool escaped from the corner of his slack mouth, running down his cheek. His pupils, hidden beneath half-lowered eyelids, struggled to focus, refusing to align properly anytime soon.

“If you say yes, I’ll stop right now. Really,” came the devilishly coaxing whisper.

Eunhyun’s voice trembled with desperation, a devilish sweetness lacing his tone as he clung to the word like a lifeline.

“Y-yes, okay!”

With a sudden, forceful thrust, the hard flesh plunged deeply inside. Tears sprang to Eunhyun’s eyes, overwhelmed by the violent surge of pleasure.

“I said yes, so why…” Eunhyun’s flushed face glowed brighter as the words escaped him, his voice breaking as he cried out once again.

“Yes!”

Eun Hyun clenched her fists tightly and cursed as the cock crushed her cervix again.

“Yes, yes, yes, yes, yes, yes!”

“Ha……. Fuck….”

With a snap, Eun Hyun’s last strand of patience snapped. The sight of Eun Hyun’s crying face as he held his cock in his stomach and screamed for pleasure was enough to shatter anyone’s patience. Eun Hyun chewed on his lower lip and let out a low groan.

“Mmmm, kkkk….”

And then, with a pop, the tip of Yi Hyeon’s penis erupted and began to shoot a torrent of fluid into Eun Hyun’s cervix. A stream of hot, hot water, which felt very different from semen, was gushing out from the inside in several streams. It was as if a hose shooting water at high pressure was inside. As the hot water pounded against the tightly closed entrance of the nursery, Eun Hyun gasped at the strange sensation she had never felt before.

“Ahhh…. What is this, hhhh, what is this… hot…, hot…, hot…! Ughhhh!”

It continued for quite some time, irritating her belly evenly. Eun Hyun struggled, pushing the sheets off the bed with her toes to get away, but Yi Hyeon wouldn’t let go of the two hands that gripped her pelvis tightly. Struggling hard, Eun Hyun tightened and loosened her inner walls without ejaculating, reaching orgasm. Instead of the white cum, only a clear liquid leaked out of her vagina.

A bead of sweat trickled down Yi Hyeon’s collarbone as he craned his neck back to shoot out the unidentifiable liquid. The intensity of his climax sent shivers through his body for longer than usual. Then, as if coming to his senses, Lee’s head fell forward again.

After shaking off the residual heat of his orgasm, Eun Hyun shuddered once more, and then asked inquisitively about the identity of the liquid that had filled his stomach along with his cock.

“Jeong… Eun Hyun, what did you do, did you… oh… piss… in me?”

“Haa, phew… pee, no.”

“Then what is it… What is this?”

“It felt so good… Haa, I got too excited, and I came…”

Yi Hyeon replied with a raspy breath, his face still flushed with lingering passion. Eunhyun glared at him with a mix of suspicion and frustration. She wanted to press him further, but the uncomfortable fullness in her stomach, heavier than usual, made her shift uncomfortably. Placing both hands on her swollen abdomen, Eunhyun grimaced.

“Ugh… It feels weird… inside my stomach… right now…”

Before she could finish her sentence, her vision blurred as Yi Hyeon effortlessly scooped her up. Her chest brushed against his, and the sudden movement made her dizzy. Instinctively, Eunhyun wrapped her calves around his waist to steady herself, her arms looping around his neck.

“The sheets are dirty. Let’s go to the bathroom and clean up,” Yi Hyeon said nonchalantly.

“What? What the…!”

Eunhyun barely had time to react as Yi Hyeon carried her without a care. Each of his steady steps sent shivers through her body. His still-stiff member, buried inside her, pressed and rubbed against her sensitive walls with every stride. The liquid filling her inner walls rippled with the motion, amplifying her discomfort.

“Heehee… Ahhh! Ahh!”

Reaching the bathroom, Yi Hyeon stepped into the tub, gently lowering her. As he pulled out, Eunhyun remained draped in his arms, her legs still wrapped around his waist. She gasped as a steady stream of nearly viscous liquid poured from her body.

The clear liquid dripped and splattered onto the floor, pooling below. Yi Hyeon’s eyes widened in fascination, unable to look away from the sight.

“Wow… It’s like my brother’s butt is peeing. It’s beautiful.”

Beautiful? What kind of sentiment is that in this situation? Eun Hyun’s muddled mind couldn’t comprehend it.

“See? It’s transparent,” Yi Hyeon said, his voice tinged with satisfaction. “I told you, it’s because I like you so much.”

Weakly lowering her gaze, Eun Hyun stared at the colorless liquid trickling down the tub drain, her thoughts clouded and chaotic.

“Yes. It’s transparent.” With that final thought, Eun Hyun lost consciousness in her younger brother’s arms.

Yi Hyeon sat quietly, gazing at his brother’s sleeping face, his own breathing still heavy. Eun Hyun was sound asleep, his chest rising and falling in a steady rhythm. Yi Hyeon couldn’t tear his eyes away. It was a face he could stare at for hours without growing tired—so flawless, so perfect, without a single unattractive feature.

Despite his earlier resolve to let Eun Hyun rest, Yi Hyeon couldn’t help himself. His fingers moved almost on their own, gently tracing the outline of Eun Hyun’s closed eyes. Eun Hyun stirred slightly, letting out a soft noise of protest, his face scrunching as if to say, “Don’t disturb me.”

Yi Hyeon’s gaze shifted to the faint dark circles under his brother’s eyes, and a pang of guilt and sadness twisted in his chest. Eun Hyun must have been exhausted, working hard all week. The thought pained him.

“It would be so much better if you didn’t have to work,” Yi Hyeon murmured softly, his voice tinged with longing. “Then you could just stay here… Eat, sleep, make love… Eat, sleep, make love…”

The sheer thought sent a wave of warmth surging through Yi Hyeon, making goosebumps rise along his skin. The image of an endless cycle of comfort and pleasure filled him with an almost overwhelming sense of satisfaction.

He leaned closer, his lips brushing against Eun Hyun’s forehead in a tender, almost reverent kiss, whispering, “Rest well, hyung… You deserve it.”

After washing his brother, who had passed out as if he had fainted, and drying his entire body, Yi Hyeon dressed him in pajamas and decided to let him sleep peacefully for the night. But even as he stood there, the urge clawed at him—an intense, almost maddening desire to rip those pajamas apart and bury himself in Eunhyun’s slick, inviting heat.

The thought of it consumed him, but he forced himself to hesitate. Eunhyun always slept so deeply when he was tired that he likely wouldn’t wake up even if Yi Hyeon indulged himself just a little. Yet, his rational side whispered caution. Eunhyun’s body was fragile, and he didn’t want to push him too far. After all, Yi Hyeon wanted to savor him for the rest of his life, a little at a time, without causing harm.

Yi Hyeon let out a long sigh of restraint, as if surrendering to the better angels of his nature, and instead picked up Eunhyun’s phone from the nightstand. The screen prompted him for fingerprint recognition, but he simply swiped to reveal the password entry screen. When he entered “1121,” the home screen unlocked immediately.

Too easy… Yi Hyeon glanced at his brother’s peaceful, sleeping face and inwardly chastised him. However, for Yi Hyeon, it wasn’t a bad thing—this simple password had given him access.

Without hesitation, Yi Hyeon tapped the yellow messenger icon and scanned the list of chatrooms. Most of the conversations appeared mundane—work-related messages or simple greetings. His eyes moved quickly, searching for one name in particular: Han Jin Seo. But it wasn’t there. It seemed Han Jin Seo had already left the chatroom.

Annoyance flickered in Yi Hyeon’s chest as he scanned the rest of the conversations more closely. Among the names, one stood out: Song Ye Na. Clicking on the chat, he found a polite exchange from just a few days before Eunhyun’s Omega manifestation. The conversation was about rescheduling or possibly postponing a blind date.

The sight of it made Yi Hyeon’s jaw tighten. He tapped on Song Ye Na’s profile with an irritated touch. Her profile picture showed her smiling brightly, a classic Beta at first glance. Below the photo, her status read: “~3/9 Paris business trip. No calls, no texts.”

Unconsciously, the corners of Yi Hyeon’s mouth curled upward. The thought of Eun Hyun canceling the blind date filled him with a quiet satisfaction. The idea that Eun Hyun belonged to him—and only him—was intoxicating.

Yi Hyeon closed the messenger app and absentmindedly opened the search app. As soon as his finger hovered over the search bar, a list of Eunhyun’s previous search queries appeared below:

“Lunch menu recommendations near Jonggak Station”

“Excel lookup error”

“How to remove coffee stains”

…

Then, something caught Yi Hyeon’s eye just as he was about to close the window with a bored expression.

“Imprinting removal procedure”

Narrowing his eyes, Yi Hyeon tapped on the search term. Several articles Eunhyun had already read were marked in purple. He clicked through each of them, reading every single one thoroughly.

“…Ha.”

So that’s what he’s been up to—moaning and crying out how good it felt while taking me inside him, only to go behind my back and search for ways to undo our imprinting. The sight of Eunhyun sleeping peacefully beside him, face unguarded, made Yi Hyeon feel both angry and bitter.

Do you know how much effort I put into making you mine? From the moment I saw you, you were always meant to be mine. We were born to imprint on each other.

But “imprinting removal procedure”?

Yi Hyeon was consumed by feelings of betrayal and spent the entire night unable to sleep.

The Next Morning

Eunhyun woke up feeling refreshed after what seemed like an eternity since his last good night’s sleep. Sometimes, sleeping too much gave him headaches, but this time, the rest felt just right, leaving his body light and energetic.

“Since it’s the weekend, I guess I can laze around a little longer.”

He pulled the cozy blanket around himself, rolling over, but his thoughts quickly turned to the events of the previous night when he had once again been intimate with Yi Hyeon.

When I’m in my right mind, I know I should put an end to this, Eunhyun thought.

Instead of firmly rejecting Yi Hyeon, he had given in, even letting out moans as he indulged in the pleasure Yi Hyeon provided. There was no way he could convincingly claim he hadn’t enjoyed it.

“Ah…”

A sigh escaped his lips.

Am I broken? Is something wrong with me?

The discomfort of revisiting those memories made it impossible for him to relax any longer. With a heavy sigh, Eunhyun tossed off the blanket and sat up in bed.

After Discovering He Was an Omega

After being officially diagnosed as an omega at the hospital, Eunhyun had started researching on his own. He had typed unfamiliar terms like “omega” and “alpha” into the search bar countless times, topics that had never crossed his mind before.

Through his searches, Eunhyun learned that no amount of scientific advancement could fully transform someone born with beta genes into an omega. What Yi Hyeon had done was merely hasten the process—Eunhyun would have eventually manifested as an omega regardless.

He also learned that when someone manifests as an omega later in life, the pheromones that should have been gradually released build up over time. At the moment of manifestation, those pheromones are released in an overwhelming surge, more than enough to strip an alpha of their rationality.

“So, that’s why Yi Hyeon has been acting like this.”

Eunhyun tried to rationalize the situation, but it didn’t stop the swirl of complex emotions churning within him.

Knowing that made Eunhyun feel a small sense of relief. He could convince himself that what had happened with his brother, and his own reactions during that moment, could be dismissed as an accident. Even if it couldn’t be erased entirely, he believed it could one day fade into something insignificant. The moment it was recognized as something serious, it would become truly irreversible, so he tried to turn a blind eye to it.

But it was like covering a pit with branches—an attempt to conceal it that did nothing to address the real issue. Worse, the pit had only grown deeper without his notice, and now even dismissing it as a mistake was becoming impossible.

I can’t go on like this. I need to talk to Jeong Yi Hyeon today.
