The Guide's Seduction
Chuuup—.
"Khh… hng!"
"Aha—!! Relax, Seung-woo. Stop resisting. The more you fight, the harder it'll be for you. Got it?"
The pink inner walls slowly swallowed his cock as she lowered her hips. At first he thought she was just teasing him, drawing it out on purpose, but he quickly realized that wasn't the case.
Her walls clung to him the moment he entered, nearly forcing him to climax from penetration alone. If she had slammed him in all at once, he would have come instantly.
"Even so, coming right after putting it in would be a waste, don't you think?"
Squeeze—.
"——!?"
"Kihit—. I told you to relax."
Her walls tightened as if demanding an answer. Her insides gripped his shaft like they were strangling him, pumping him full of vicious pleasure. It felt like a separate organ designed solely to milk a man's seed.
Only then did he understand why she kept telling him to relax. It wasn't just a warning. If he tensed up even a little in this state, he would come.
His brain, flooded with dopamine, screamed at him to let go, but he desperately held on. Because he had a gut feeling that once he came inside her body, he would never be able to return to who he was before.
Like a drug, he knew he would end up living just to taste her flesh every day.
Pouring every ounce of his will into delaying his climax, he realized something. If she moved even a little, he would definitely come. But contrary to his expectations, she didn't push him toward release right away.
"Good boy, our Seung-woo. That's it, that's it… Just keep relaxing like that… You're doing so well."
She leaned down, hugging him tightly, and gently stroked his hair like a mother soothing a child. Or like a kind older sister.
Perhaps because of that, his body slowly regained a sense of calm, and a languid yet fulfilling emotion welled up in his chest. Her viciously skilled pussy didn't move, but instead repeatedly tightened and loosened, delaying his orgasm.
Thanks to her actions, things had been dangerously close, but his climax had been postponed somewhat. With a bit of mental leeway returning, a question arose in his mind.
Why wasn't she devouring her helpless prey right away?
"Ahat—. Why? Did you think I'd just pound your cock like some wild animal? Seung-woo, do I look like that much of an idiot? Did you think I wouldn't know anything about men?"
Seeming to sense his confusion, the Guide brought her lips close to his ear and whispered softly. Her deliberately seductive voice reignited his arousal.
"The more I tease you…"
"Kgh, hng—!?"
Her long, slender fingers gently caressed his chest. Every time her fingertips brushed over his skin, his body trembled on its own. As she rocked her hips ever so slightly, sending pleasure through his buried cock, the composure he had barely regained began to slip away again.
"The more I tease you… the stronger the pleasure becomes… the thicker the cum… the longer the afterglow… the memories that stay in your head. Everything you do with that woman… will never leave your mind for the rest of your life."
The Guide continued whispering, her lips still pressed against his ear.
"That… Evil Eye—."
The moment he opened his mouth, thinking this was getting really dangerous—
"I love you, Seung-woo."
It was the final blow.
When she confessed to him in the voice of his childhood friend, the one he had once held deep feelings for, in Seong-ha's voice, the physical pleasure and the emotions in his heart connected.
Love.
Or perhaps affection.
He couldn't tell. But whatever it was, it was clear that both his body and mind were being pulled into something he could never escape from.
Too late, he realized that this demonic existence was trying to steal not just his body, but his mind as well. By giving him not only physical pleasure but emotional joy, she intended to bind him to her forever.
"Aha—!! Men are so simple, I love it! That's why… you're so adorable."
The Guide sat up and looked down at him, bursting into laughter after checking his expression. Then she cupped his cheeks with both hands, bringing her face even closer, her eyes scanning his face from every angle.
As if savoring the scent of a delicious meal before eating it.
"Ha—. The more I look, the more arousing your expression gets… Well then, since you're nice and ripe, shall I eat you up now?"
Chuuup….
The Guide lifted her hips slightly. The tremendous suction and pressure made it feel like his cock was being pulled upward with even that small movement.
Dangerous.
His instincts screamed alarms as he imagined what those raised hips were about to do, but there was still nothing he could do.
Thud—.
"Kuhk!"
When her lifted hips came down gently, a groan that sounded almost like pain escaped him. His brain tingled. The pleasure that shot up through his lower body and spread through his entire being took control.
As he reached out with his unmoving hand to somehow escape it—
"I'll take care of everything. So just stay still for me, okay?"
Treating his miraculous resistance as mere tantrum, the Guide snatched his hand and pinned it to the bed before starting to rock her hips again.

Thud—. Thud—. Thud—.
"I love you, Seung-woo… I love you more than anything else in this world… I love you, I love you, I love you… I love you more than anyone… You're the only one for me… I can't live without you… So let's… stay together forever."
He couldn't tell if the affection the Guide whispered to him was a lie meant to claim him, or if it was genuine. But whichever it was, the tender words and the physical pleasure being carved into him were clearly merging into one, devouring his very existence.
Thud! Thud! Thud! Thud!….
"Kuhk—."
Twitch.
His cock, which had been twitching wildly as if begging for mercy, suddenly stopped thrashing, as if meeting its end. Sensing the unstoppable climax approaching, all the questions, stray thoughts, worries, and fears left in his mind vanished.
What dominated his body and mind now was only pleasure and the overwhelming emotions toward her. Tangled together, they pushed him into a pit he could never crawl out of.
"——!!"
A crushed scream burst out like a final death cry. A blush rose on the Guide's face as she watched his expression in real time, and a bright smile bloomed across it. That smile held a contradiction—terrifying and dangerous, yet beautiful and captivating.
"Yes, come inside me like that. My cute little puppy."
A voice that was both unfamiliar and familiar echoed from somewhere. Surprisingly, it came from the Guide's mouth. That voice, which sounded like someone else, was neither his childhood friend's nor the Guide's usual tone.
For a brief moment, his returning consciousness tried to grasp that voice. He had definitely heard it somewhere before—
"U… Oppa…."
Just as he was about to reach his climax and his life was about to take an unexpected turn, a sleepy voice rang out, drawing both his and the Guide's gazes to the side.
"Uung…."
Ha-rin, who had been lying unconscious on the bed, looked like she was about to wake up. The Guide's smile vanished as she glared at her with cold eyes. The chilling emotion she directed at Ha-rin—an existence that was nothing more than an object to her—at this critical moment when she could finally claim him, was something he had never felt before. He thought the best way to describe that atmosphere was killing intent, and quickly opened his mouth.
"Don't!"
The Guide's hand, which had been reaching for Ha-rin's neck, stopped mid-air at his cry. She looked at him, her brows furrowing deeply with hesitation, before instantly turning into black liquid and melting into his body, disappearing.
"Oppa…?"
Ha-rin, now fully awake, rubbed her eyes and recognized him. It was fortunate that the Guide had hidden her form, so Ha-rin didn't know her true identity. Though she was brainwashed and her memories could be erased anyway, the fact that she had nearly died just moments ago remained unchanged.
Her drowsy expression changed the moment she spotted his still-twitching, unspent cock, and her face turned lewd again.
"Ah… Oppa, you're hard again. I'll—"
"Don't."
"S-sorry, Oppa…!"
His voice came out cold, perhaps to sort out the emotions left behind by the Guide. At his single word, Ha-rin shrank back like a puppy scolded by its master.
An awkward silence hung in the air for a moment before she hesitantly spoke after several moments of indecision.
"Oppa… I have a favor to ask you."
"What is it?"
His cock was officially closed for business now. As he pulled on his underwear and asked indifferently, Ha-rin said something unexpected.
"I… want to get revenge on Ji-ah."
"What?"
"My friend you know, Lee Ji-ah. I want to get revenge on my one and only best friend in this world."
He had already adjusted her so she would feel negative emotions toward Ji-ah. He had planned to use those feelings soon to shake Ji-ah, her final target, but he hadn't expected her to bring it up so quickly. Or perhaps the hatred toward Ji-ah had already taken root deep in her heart.
"Can you… help me? In exchange… I'll give you everything. My body, my heart…"
Even as she asked him cautiously, a crooked smile formed on Ha-rin's lips.
"Kik!"
He chuckled at the sight. Give him everything? He already owned every part of her. Still, the fact that she was saying this of her own volition was arousing. The brainwashed Ha-rin was moving exactly as he wanted, like a puppet. Watching her believe that her current emotions and thoughts were entirely her own and following them obediently, he felt the corners of his mouth lift even higher.

"Huu—."
"Unni, is something wrong?"
Ji-seo, who had been lounging on her older sister Ji-ah's bed as usual, grew concerned at her sister's soft sigh. Her one and only sister, the most precious person in the world. When that person sat in the same room with a worried expression, she couldn't help but pay attention.
"Ah… Yeah… It's just…"
"What is it? You don't have any secrets from me, right? …Ah, maybe things with your boyfriend aren't going so well…?"
When her sister hesitated to answer, Ji-seo cautiously guessed and asked.
"N-no! We haven't even had that date yet!!"
"Then what is it? Just tell me honestly."
Seeing her sister's face flush red in surprise, Ji-seo sat up on the bed and faced her with a serious expression. Moved by her younger sister's earnest attitude, Ji-ah hesitated for a moment before opening her mouth.
"It's… because of Ha-rin…"
"Huh? Ha-rin unni??"
Ji-seo tilted her head at the sudden mention of Ha-rin. She had assumed it was something related to her boyfriend. Because she thought it was impossible for her sister to be worried about her best friend Ha-rin. That was proof of how close the two were, and Ji-seo, who also knew Ha-rin well, naturally thought the same.
From childhood until now, Ji-seo had often played with Ha-rin as well. To Ji-seo, Ha-rin was like a real older sister. That was why, because they were so close, she understood better than anyone how dearly Ha-rin cherished her sister.
"She… Ha-rin seems to be avoiding me… No, it's not just avoiding. It feels like she hates me…"
Her sister's voice trembled with tears. Normally she would have rushed over to comfort her right away, but the content was so shocking that the thought didn't even occur to her first.
"Eh???"
Ji-seo's eyes widened as she raised her voice. That Ha-rin unni. Hating her sister? Ha-rin unni, who cherished her sister even more than she did herself? It was more shocking than hearing that the world might end.
* *
'Why is Ha-rin unni… Why is she distancing herself from unni? No, it's not even distancing at this point… It's basically saying she wants to cut ties… From what unni said, there wasn't even any particular incident… Or maybe that oppa was the trigger… She said his name was Seung-woo oppa, right? Unni mentioned that Ha-rin unni has been hanging out with that oppa a lot at college lately, without her… Because of love? But even so, Ha-rin unni wouldn't treat unni like that… She said she looked at her with contempt… Ignores her when she talks, doesn't reply to messages or KakaoTalk… She even heard Ha-rin badmouthing unni to other friends at college… What on earth happened…?'
Ji-seo sat on a park bench near her house, the sunset behind her, lost in deep thought over what she had heard from her sister the night before. Even now, the sound of her sister sobbing as she explained what had happened with Ha-rin was vivid in her ears. While comforting her sister, Ji-seo had cried a lot too. It was too… pitiful and sad. It was the first time she had seen her sister so hurt.
'Should I meet with Ha-rin unni…? But no matter what, it's between the two of them, so me stepping in as the younger sister might be… No, Ha-rin unni and I are really close too… At that point, I could ask—'
"There you are."
"……!"
Ji-seo looked up, startled out of her thoughts by the sudden voice.

"Huh? …Unni?"
It was Ha-rin. She couldn't hide her surprise at the sudden appearance of the person who had been filling her mind just moments ago.
"You weren't home, so I came here, and sure enough, you were here. You always come to this park when you have something on your mind, don't you?"

Ha-rin smiled at Ji-seo. Looking at that smile, Ji-seo felt something strange. Clearly, the person in front of her was the Kim Ha-rin she knew. The face, voice, and way of speaking were all the same—her friend, someone like a sister. Yet right now, she felt like an entirely different being wearing the shell of Kim Ha-rin.
"Want to talk for a bit? I have something to say about Ji-ah. Ah, before that— I was thinking of introducing an oppa I know to you."
"Huh?"
Thud.
Ji-seo turned her eyes toward the sound of footsteps. A man was approaching beside Ha-rin. It was a face she had never seen before, but remembering what her sister had said, she realized he was Yoon Seung-woo.
"Hello. So you're the little sister Ji-ah cherishes so much?"
He approached slowly and spoke with a smile. It was a neat smile, but Ji-seo felt an inexplicable sense of unease, her expression turning dazed.
"Nice to meet you. Let's get along well from now on, shall we?"
As she took in the sight of him extending his hand, Ji-seo began to feel an unknown anxiety.
