Good Night, Brother! - Chapter 3.7 (R19)

Noticing Eunhyun’s confusion, Hyunhyun decided to explain it more gently to his naive brother, who was still struggling to grasp the physiology of Alphas and Omegas.

“Hyung, did you know that everyone is born with pheromone glands?”

It vaguely sounded like something from a high school textbook. Eunhyun waited silently for him to continue.

“Betas have pheromone glands too, but they’re barely functional, which is why they’re classified as Betas. However, there are cases where people stay Betas into adulthood and later develop into Alphas or Omegas, right?”

That much was common knowledge. Eunhyun had seen it mentioned frequently in news reports and articles.

“It’s just that their pheromone glands started working a little later than those of other Alphas and Omegas.”

“……”

“I noticed it. Even before I manifested as an Alpha, you had a sweet smell that drove people crazy.”

“Sweet smell?” Eunhyun thought to himself. I’ve never heard of such a thing.

“I didn’t even know what it was when I was younger, but it turned out to be my brother’s pheromones.”

“……”

“Only I knew my brother’s Omega pheromone, the one even the hospital didn’t detect. I made it bloom.”

“……”

Yi Hyeon’s gaze softened, his voice tender as he added, “Beautiful and precious things, like stars and flowers, are named by the person who finds them. So you’re mine, and I’ll keep you.”

True to his word, Hyun looked at my brother with ecstatic eyes, as if he was looking at something priceless. With each step he took, Eun Hyun stumbled backwards, gripped by a strange sense of fear and nervousness. Before she knew it, her back was against a cool wall. Eun Hyun’s large shadow completely obscured her.

“What the hell are you… talking about….”

“Don’t you understand? You’re the Omega for me.”

Stepping up to Eun Hyun’s nose, Yi Hyeon gently pressed his lips together in a soft peck. It was a courtship kiss, as if asking her to open her lips, but when Eun Hyun forced her lips to stay closed, he bit down painfully.

‘Ah!’

Surprised by the sudden pain, Eun Hyun’s mouth gaped open. Trapped between Lee Hyun’s hard body and the wall, Eun Hyun had no choice but to accept the invading tongue. The tongue slithered around in her mouth like a slug, probing her vulnerable parts and sucking up all of her saliva.

It was strange. He should be horribly grossed out and disgusted to be kissing Eun Hyun like this, even though he’s a man and he’s his brother, but he shouldn’t…. His eyes kept closing and his body relaxed, wanting to just lean into him like this.

Eventually, Eunhyun wrapped her arms around his neck, and a moan of pleasure escaped her mouth.

‘”..Hmmm, mmmm, yeah….”

Every cell in my body was craving my sister’s pheromones.

“Oh, that feels good…… some more….”

Eun Hyun’s body was now leaning heavily against Yi Hyeon’s, sending out a stream of sexual pheromones that danced around him. Yi hyeon loved the fact that he couldn’t control his pheromones and was completely oblivious to the implications of what he was emitting.

Eun Hyun’s breathing grew ragged as he turned his head this way and that, actively seeking the kiss, and he slid the tip of his tongue across the crack beneath his lips, caressing it, swirling his entire tongue around it, savoring the taste of his brother’s tongue.

If he had a longer tongue, he would have slipped it past his brother’s uvula and down his throat, and he would have fucked him. Yi Hyeon bit down lightly on Eun Hyun’s bottom lip, wistfully, and then Eun Hyun stuck out his tiny tongue, his moist eyes begging for more. The sight of him looking up at me, his eyes unfocused with dark pleasure, his red tongue between his parted lips sent a shiver through my body.

I slipped my hand inside his pajama T-shirt as I sucked his cute tongue into my mouth. The skin that had been moist against his palms as a beta, giving him pleasurable sensations, now reeked of Omega Tea. The softness of the Omega’s silky underside over his lean muscles drove Hyun Lee crazy.

He ran his fingers up the slim waist, and Eun Hyun moaned into his throat. He gripped his brother’s ribcage with both hands and traced his thumb over his nipple. The pale pink bumps stiffened and asserted themselves with just a kiss on such a small subject.

The nipple tingled at the slightest touch, probably from the bullying last night. Eun Hyun’s lips parted in surprise and she pulled back.

‘Hmph! That… hurts….’

‘My brother, it hurts? Why?’

‘That’s because you, yesterday…!’

Eun Hyun couldn’t finish his sentence and shot a glare at Yi Hyeon, his lips pursed tightly, one of those expressions that Yi Hyeon had loved so much since he was a child. Yi Hyeon smirked and pretended not to notice.

‘Did I hurt your nipples yesterday?’ “…….”

“Again? Did I hurt you again, huh? I’m such a mean sister. I know.”

Eun Hyun lowered his hands from around his brother’s ribcage and squeezed the rounded cheeks. Eun Hyun bounced on his waist as he felt his anus gaping horizontally inside his underwear.

“Hmph, don’t spread…!”

Yi Hyeon grabbed one of his brother’s hips over his clothes, spreading it apart, and slid his other hand roughly into his underwear. As if inspecting, Hyun ran his fingertips over the tightly puckered hole. Eun Hyun shuddered at the comparative coolness of his fingers against her heated hole.

‘Ugh… don’t touch…!’

“Hyung, it’s… hot here. Is it because of me?”

“Oh, no… stop, take your hands off…!”

In my sane mind, I should be avoiding my brother’s touch like this…. My mouth told me to take my hands away, but honestly, it felt so good… the sensation of my brother’s fingers touching the most sensitive and vulnerable part of my body, an intimate place usually protected by my underwear… it just felt good.

Eun Hyun wasn’t even releasing his pheromones, but he was soaking in the scent of the imprint on his skin.

‘Haha, hyung… it’s swollen here.’

As Eun Hyun’s cheeks rubbed against his brother’s cheeks as if he was getting excited from touching her pussy, he breathed hot breath into his earlobe.

“I want in…….”

Eun Hyun pushed his brother away from him, sobered by Yi hyeon’s heated, seductive whisper. Without warning, Yi hyeon pushed back, his hand slipping out and the band of Eun Hyun’s trousers and underwear sliding back into place. He couldn’t believe he was breathing heavily with excitement as he performed a sexual act with his brother.

“Hah… you go away.”

“Why? I want to….”

Eun Hyun’s hip slammed into the wall as she backed away from Hyeon, who had taken a step closer to her, and a throbbing pain shot up her spine. Tears welled up in her eyes.

‘Ow! That hurt…!’

Eun Hyun asked with wide eyes.

“It hurts? Why?”

“Then how could it not hurt?”

“The Omega pussy… I thought it would be fine.”

“Omega Bo….”

Eun Hyun glared at Yi Hyeon with an expression of disbelief. Yi Hyeon gently rubbed the back of his hand across Eun Hyun’s soft cheeks, then brushed back the bangs that had fallen haphazardly over her forehead from her sleep. Eun Hyun frowned, as if she were dealing with a petulant child.

“Maybe it’s because she’s still a baby.”
