Good Night, Brother! - Chapter 4.5 (R19)

“Haha, just once. I’m dying to see you.”

“Hang up.”

Eunhyun furrowed her brow, left a short comment, and pressed the end call button. The phone didn’t ring again, as if he was immersed in masturbation. Eun Hyun looked down at his penis, which had now taken shape with a rush of hot blood.

“Fucking crazy….”

I sighed, realizing that if Yi Hyeon hadn’t called, I might have actually stimulated myself to climax.

Eunhyun sat at the kitchen table, listening to the faint hum of the washing machine echoing through the living room. His eyes were open, but they weren’t focused on anything in particular. His mind felt foggy, as if it were shrouded in a thick, white cloud.

Soon, Eunhyun let out an anguished groan, clutching at his hair in frustration. He shook his head violently before slumping forward, his disheveled hair falling over his face.

“Why the hell did I do that?”

Before manifesting as a recessive Omega, Eunhyun had been a Beta male with an average sex drive—not overly restrained, but not excessively virile either, sitting comfortably in the middle. Watching adult videos or thinking about such things would naturally elicit a reaction from his lower body, like any other man. But never—not even during his first experience in his twenties—had he ever felt so uncontrollably aroused, as though under the influence of an aphrodisiac. He swore he’d never lost his reason like that before.

The experience he’d just had in his brother’s room felt… primal. Like a runaway locomotive, completely out of control, driven purely by his libido, chasing pleasure with reckless abandon.

“It’s not some kind of animal…”

Eun Hyun had captured its exact essence without realizing it. In reality, the pheromones of Alpha and Omega were not much different from the chemicals that animals emit to communicate.

Typical Alphas and Omegas, who emerge as early as the tender age of ten, naturally develop the ability to read other people’s pheromones as they grow. They start with relatively simple and obvious emotions, such as joy, sadness, love, and hate, and by adulthood, they are able to discern more nuanced cues, including sexual intentions. In essence, Alphas and Omegas can communicate entirely through pheromones.

Just as two married individuals combine their genes to create a child, when an Alpha and an Omega imprint, their pheromones mix to form an unbreakable bond. They become mutually dependent on each other’s pheromones, and no one else can perceive their unique scent. Alpha and Omega imprints are akin to long-term lovers who grow increasingly similar over time. Their bond strengthens, allowing them to intimately and deeply understand each other’s emotions.

It’s no wonder, then, that Eunhyun momentarily lost reason when exposed to Yi Hyeon’s pheromones, saturated with desire—desire that Yi Hyeon must have fantasized about countless times. Eunhyun, who had only recently transitioned from being a Beta, found this new reaction unsettlingly unfamiliar.

My Beloved Friday

You know, I like you as much as Friday.

I really do.

A song in praise of Friday played through Eunhyun’s earphones. To be able to love someone as much as Friday—surely, that was a love that would never come again in this century.

Humming the lyrics to herself, Eunhyun walked along the tree-lined boulevard of Jongno. Her steps felt light as she made her way toward the subway station. Back in college, she never imagined she’d look forward to weekends this much.

The subway was packed with office workers heading home for the day, and Eunhyun struggled to squeeze into the car. For once, she was able to forgive the man behind her whose oversized backpack was pressing into her back.

Beep. Ding. Click.

As Eunhyun reached the front door, his fingers froze mid-air while keying in the combination: 1, 1, 2.

Wait, isn’t today Jung Yi Hyeon’s return day?

Eunhyun’s face turned pale as memories of his relationship with his brother, the imprinting, and the disastrous video call from the night before flashed through his mind. He remembered how he’d completely lost control, consumed by the overwhelming pheromones.

Standing frozen in front of the door, Eunhyun thought, If I see Yi Hyeon, I might lose control again.

Click. The sound of the door lock releasing broke his thoughts as the door opened from the inside.

“Hyung, you’re home. Why aren’t you coming in? Did you forget the password?”

Eun Hyun spoke with his usual affectionate smile, trying to steady his startled heart.

“Hey, what the hell? Open the door knowing who it is. What if it’s a thief?”

“Hyung, I can see it on the intercom.”

“…….”

That’s right. Their house had an intercom. However, Eun Hyun, having gotten into the habit of always going to the door and asking “Who’s there?” while living in her previous studio without an intercom, rarely used it.

When Eun Hyun hesitated at the doorway without entering, Yi Hyeon grabbed her arm with his large hand and gently but firmly pulled her inside. Eun Hyun’s body was pulled through the threshold and into Yi Hyeon’s arms as the door clicked shut behind her.

Standing at an angle, Eun Hyun found her face buried in Yi Hyeon’s broad chest. The familiar scent of the forest filled her nostrils, accompanied by the slow, steady rhythm of his heartbeat: thump, thump, thump. A sense of security. Her brother’s arms were undeniably giving her a comforting sense of security.

Eun Hyun’s eyes fluttered shut as the soothing pheromones melted away the exhaustion of the day. The arm around his shoulders tightened even further, and a low, almost breathy whisper reached his ear.

“Hyung, I’ve missed you so much….”

Anyone overhearing might have thought they’d been apart for years. Eunhyun let out a disbelieving laugh.

“I can’t believe you missed me for five years.”

“Back then… I thought I was going to die.”

“Well, you didn’t. You’re alive and doing just fine.”

“You don’t understand.”

“……”

“You don’t know anything….”

Yi Yeong buried his nose in Eun Hyun’s shoulder and rubbed his face against it, hoping to get another piece of his imprint’s pheromones, and soon his hot breath was on the white neckline exposed through the collar of Eun Hyun’s shirt. Hyeong’s lips brushed past her ear, pressing against her cold cheek.

With his hot lips, he gently pecked Eun Hyun’s lips, as if asking permission to open them. The inside of Eun Hyun’s chest tickled, sending a tingling sensation down her spine.

Yi Hyeon’s tongue darted in through the gap in her open mouth, tangling with hers.

As the kiss deepened, Yi Hyeon wrapped his arms around his brother’s waist, holding him tightly as his legs went limp. He pushed Eun Hyun against the shoebox door and slid his thigh between their crotches. I could feel Eun Hyun’s cock, as hard and swollen as mine, against the fabric of his lower body.

“Haha, yours is very hard.”

Frantically, Yi Hyeon smeared his saliva all over Eun Hyun’s face like an animal, marking his territory, and brought his knees up to crush her. Eun Hyun cried out as her delicate flesh was stimulated by his hard kneecaps, and she grabbed his upper arm hard.

“Hmph, don’t…!”

“Don’t do it when it’s bigger, really?”

“Hmph, no…! It’s not bigger…!”

Eun Hyun’s eyes squeezed shut as he repeatedly stabbed downward as if he were chopping with his knees, his wide kneecaps crushing her scrotum, penis, and perineum evenly as they were trapped under her clothes.

“Ah… As soon as I got home from work, I thought, what the hell….”

Yi Hyeon’s husky voice reached Eun Hyun’s ear, his lips brushing dangerously close to the lobe as Eunhyun gasped helplessly for breath.

“Hyung, didn’t you use this while I was gone?”

“What…?”

‘Didn’t you use your cock and pussy?’

“Oh, I didn’t!”

“Well, seeing as how you’ve been masturbating so lasciviously, you must have been using it somewhere else.”

“Am I crazy?”

“You lie all the time—I can’t trust you.”

“Haah…. Get out of my way.”

Eunhyun tried to push his brother out of the way, but his rock-hard body didn’t budge.

“What did this bastard eat to make his body like this…?”

“Show me so I can see if you used it or not.”

“Show me what! I didn’t use it. Get out of my way!”

“Hyung.”

When Eunhyun looked up with a frown at the sound of his name being called, he smiled cheerfully.

“Anyway, if you don’t show it to me now, I’ll see it when I go to sleep.”

“…….”

A few minutes later, Eunhyun was lying on his bed, propped up on his knees and hands. He wore a shirt and tie on top, with nothing on his lower body except for socks.

Yi Hyeon’s gaze slowly wandered, taking in Eunhyun’s pale, smooth buttocks, moderately fleshy thighs, and shapely calves. There was something captivating about his naivety and innocence, the way he followed instructions without question—it was unbearably arousing.

Unaware of what Yi Hyeon was thinking, Eunhyun’s mind replayed the words he had heard earlier.

‘I’m going to bite it and suck it all night like last time, melt it down, and then I’m going to stick my cock in it to make sure it’s not used, and I’m going to make you cum ten times with my cock until it’s nothing but water, and I’m going to keep my cock in your pussy all weekend because I don’t want any other cock in there.

In my twenty-five years of life, I’d never heard such a vile and promiscuous threat.

Bringing his face close to Eun Hyun’s back, Hyun grabbed her nicely fleshy cheeks and spread them apart. The hidden hole between her buttocks flinched reflexively as the cool air met it. Lee Hyun smiled softly and blew his breath into the pink folds. Startled, Eun Hyun’s body jumped up angrily.

“Hmph, don’t!”

Yi Hyeon started gently probing the puckered opening with the tip of his thumb. Eunhyun stiffened and protested.

“Why, why are you touching it? You said you were only going to look at it.”

“How can you tell by just looking?”

“You said you could tell by looking.”

“I said, ‘show me,’ not ‘tell me.’”

“…….”

Eun Hyun opened her eyes and felt as if her nose had been cut. But at the same time, I didn’t know what to say, because it seemed like she was just making things up.

While Eun Hyun stood still, Lee Hyun used both thumbs to spread her folds wide. The tightly closed hole opened up horizontally, and the inner walls near the entrance popped open, and the sound of the walls falling away from each other could be heard. Yi Hyeon thought he could see why they called it the lower mouth. This, too, was clearly a mouth that existed below. A mouth that sucked my cock deliciously.

Yi Hyeon played with his brother’s lower mouth, opening and closing it. Every hair on Eun Hyun’s body stood on end at the inexplicably strange sensation of a hole opening and closing against his will, and when something hot and fleshy engaged the opening, Eun Hyun’s calf, which had been lying flat on the bed, jerked upward.

“Ah! What are you doing…! Hmm, that’s weird…!”

Eun Hyun’s eyes widened as she turned her head and saw the identity of the thing behind me. Eun Hyun was licking my pussy with the tip of his pointed tongue. Eun Hyun couldn’t believe what was happening. Sucking on such a place was beyond her common sense.
