Good Night, Brother! - Chapter 8.7

Despite herself, Eunhyun’s body continued to respond uncontrollably, her inner walls spasming and contracting violently. The soft, yielding flesh inside clenched around Yi Hyeon’s cock, milking him relentlessly as her own body betrayed her with the undeniable evidence of her pleasure. Yi Hyeon’s goal—to fill his Omega completely—was achieved. His movements became sharper, burying himself as deeply as possible, his glans pressed firmly against the entrance to her womb.

Moments later, Yi Hyeon’s body tensed. His urethral opening twitched, and with a guttural groan, he began to release.

“Haah… khhhh, khhh…!” Yi Hyeon gasped as waves of climax surged through him.

“Ahhhh… ahhh… ahh… ahhhh…!” Eunhyun moaned uncontrollably, her voice rising as her body trembled beneath him.

Eunhyun felt like her very soul was slipping away as Yi Hyeon thrust deeply, his cock continuing to grind against her, thick, thick, even as he came. Her inner walls clung to him desperately, squeezing and pulsing as if to wring every last drop of his release. Yi Hyeon arched his back, his head thrown back in bliss as tremors of pleasure coursed through him.

“Haah… huh… fill me, hyung… deeper… huh…” Yi Hyeon groaned, his voice rough with ecstasy, as his body shuddered one last time in satisfaction.

After several intense releases, Yi Hyeon panted heavily, resting his weight on Eunhyun’s back. His chest rose and fell as he tried to catch his breath. Eunhyun, exhausted and overwhelmed, closed her eyes and leaned into his brother’s affectionate touch. Yi Hyeon’s hand moved gently through her hair, as though soothing her after the hard work of their union.

Once satisfied, Yi Hyeon stepped away momentarily, leaving the room and returning shortly after.

Normally, Eunhyun would have been suspicious of his approach—especially with one hand hidden behind his back—but in her drained state, she didn’t have the clarity or energy to question him.

Yi Hyeon resumed stroking her hair, his touch steady and comforting. Eunhyun lay on her back, breathing heavily, her body sinking into the mattress. Her eyes blinked slowly, barely open, as she surrendered to the pleasant sensation. Yi Hyeon’s voice came low and steady, as though he had something important to say.

“You know,” he began, “I think my brother has too much water. Omegas are supposed to be used only through their pussy, but it’s hard when water keeps coming out of your cock.”

Eunhyun frowned slightly, unable to grasp the full meaning of his words. As a long-time beta, she had no way of verifying the truth behind the claim, nor did she have the energy to argue. Instead, she whispered softly, her voice laced with sweetness.

“I’ll help you.”

The words hung in the air. Eunhyun didn’t know exactly how she intended to help, nor did she have the strength to press for details. Her mind, foggy with exhaustion, allowed her to simply lie still and watch helplessly as Yi Hyeon worked.

Without warning, a soft cloth was pressed gently over her eyes, blocking her vision. An elastic band was fastened around the back of her head. Alarm bells rang faintly in Eunhyun’s mind, and she struggled to speak through the haze.

“Jung Yi Hyeon… What’s going on? Why are you covering my eyes?”

“It’s fine,” Yi Hyeon replied calmly.

“No, it’s not okay!” Eunhyun protested, panic creeping into her voice.

Her hands instinctively moved to pull off the blindfold, but Yi Hyeon grabbed her wrists, pulling them upward in one smooth motion. Before Eunhyun could process what was happening, she felt something soft yet firm wrap around her wrists.

Click, click, click.

Her wrists were now restrained with fluffy cuffs. Yi Hyeon connected the chain in the center of the cuffs to the iron bars of the bed frame. His voice was soothing as he reassured her.

“They’re just play cuffs. They won’t hurt.”

“What? What cuffs? You’re crazy! Take them off!” Eunhyun shouted, her voice rising in panic.

Despite her protests, the cuffs remained in place, leaving Eunhyun both confused and at the mercy of Yi Hyeon’s intentions.

“You don’t understand what I’m thinking. I’m just worried about hurting you.”

I didn’t bother to add that my brother was so painfully intolerant of injections that he despised them with a passion.

The sight of Eunhyun, bound and wearing a black eye patch that sharply contrasted with his pale skin, along with the faux fur-lined black handcuffs, was strangely sadistic.

Barely able to resist the urge to tease his brother further—to suck on his sensitive nipples or shove himself into his helplessly exposed backside—Yi Hyeon popped the cap off the tube of love gel with his teeth. He squeezed a generous amount onto the smooth silver shaft of the urethral plug, its surface gleaming in the dim light.

Turning his attention back to Eunhyun, Yi Hyeon grinned at the sight of his brother’s already stiff, dripping cock. It was so adorable, so embarrassingly aroused. A soft giggle escaped his lips as he reached out to run his fingertips over the sensitive glans, causing Eunhyun to squirm and shake his head.

“By the way, hyung, why is your cock standing up?” Yi Hyeon teased, his voice laced with amusement.

“…Th-this… this, it’s just…!” Eunhyun stammered, unable to provide an explanation.

Though unsure of Yi Hyeon’s exact intentions, Eunhyun’s body betrayed him, blood rushing to his lower half reflexively. He tried to move his legs in an attempt to hide his arousal, but Yi Hyeon spread them wide, pinning them firmly atop his own muscular thighs. His grip was strong, preventing any escape as his hand wrapped around Eunhyun’s shaft, holding it steady.

Unable to see what was happening, Eunhyun asked nervously, “What… what are you going to do? Huh? Can I—ah! Hmph!”

He cried out as the gel-slicked tip of the iron plug brushed against his urethral opening.

“Ahhh! What is it? It’s cold!” Eunhyun exclaimed, shuddering.

“If you move, you’ll get hurt, so stay still,” Yi Hyeon warned.

At the mention of pain, Eunhyun stiffened, his rib cage rising and falling as his breathing became erratic. Despite the rising anxiety, his body remained still, tense with anticipation.

Yi Hyeon, concentrating intently, began to insert the plug with the precision of threading a needle. Thanks to the generous coating of gel and the slick Cooper’s fluid already present, the slender metal shaft slid into the cramped opening without much resistance. Eunhyun’s shoulders tensed as he felt the foreign object stretching a passage meant solely for expulsion. Unable to see, every sensation was heightened, his focus solely on the unfamiliar intrusion.

“Hii… what are you doing? What are you putting in there?” Eunhyun’s voice trembled.

“Remember? We bought it together in Hongdae. A urethral plug.”

Eunhyun’s face turned pale as he recalled the stainless steel device that resembled a grenade pin. “You’re crazy! You bought it for yourself! Take it out—now!”

“Why? Does it hurt?” Yi Hyeon asked, feigning concern.

“Ah… No? It doesn’t hurt…” Eunhyun admitted hesitantly, his voice soft and uncertain.

Yi Hyeon smirked knowingly, as if he had expected that response. If Eunhyun had been able to see the insertion with his own eyes, he would’ve likely screamed in protest. But in his blindfolded state, his expression, with slightly furrowed brows and parted lips, conveyed more fear than actual discomfort.

A sudden moan escaped Eunhyun as the plug pressed against a particularly sensitive spot deep within his urethra.

“Aaah! Aaah…! Over there… huh… ah…”
