Chapter 1 — My Friend's Lover, Jin-hee

Sarah Jin thought of it as a swamp. A slow, silent sinking into something she hadn't even noticed pulling her under.

“Take good care of my girlfriend, okay?”

“Yeah, yeah… sure thing, man.”

As soon as Sarah Jin stepped into the car, David Seung closed the door, gave a casual wave to Michael Min—who was still grinning proudly, as if showing off his prize—and climbed into the passenger seat beside her.

“The last Saturday of next month, right?” he asked.

“Huh? Oh… yes…”

Sarah Jin answered, flustered by the sudden question.

It was such a strange feeling. When she'd first met David Seung—Michael Min's friend—next month would mark their wedding, she'd thought he was just an ordinary man, unremarkable. But then, when Michael Min had to rush back to the office due to an emergency, David Seung, who happened to live in the same direction, offered her a ride. She hadn't wanted to, but Michael Min insisted, and David Seung didn't seem unpleasant, so she'd agreed. Yet the moment the car pulled away, the atmosphere inside—the intimacy of just the two of them—began to feel oddly charged. And now, this abrupt question had caught her completely off guard.

“Should I congratulate you?”

“What? On what?”

“Ha… I just feel a little regret, that's all. Knowing such a beautiful woman as you will soon belong to another man…”

Sarah Jin froze. Her words vanished.

David Seung—Michael Min's friend—his words were dangerously smooth. Was it a compliment? Or something more, something like seduction? But what mattered most was that it didn't feel wrong at all. In fact, her cheeks flushed with warmth.

“I hope you won't feel that way anymore.”

“What do you mean?”

“If you don't think of me as another man's woman… then you wouldn't feel regret, would you?”

Sarah Jin gasped.

His hand, which had been resting on his own thigh, slid slowly over and gently covered hers.

Her heart began to race. Instinctively, she turned her hand over, a small act of resistance. But instead of pulling back, David Seung simply placed his hand back on hers—and then, naturally, interlaced their fingers.

“So soft… your hands, Sarah Jin… makes me regret even more.”

She couldn't move. Couldn't respond. Her heartbeat pounded louder, faster. And as if reassured by her silence, David Seung slowly increased the pressure of his grip.

Suddenly, Michael Min flashed in her mind. The man she'd met through her parents. It had taken him two months just to hold her hand. But for now, she was trapped in this moment.

“We're here. I should get out.”

She spoke as David Seung pulled into the dimly lit parking lot in front of her apartment.

“You're leaving already? Wait a moment…”

“What?”

“I don't want to let you go like this… not while you're still another man's woman.”

“What are you—?”

Her hand was still in his. She could feel the strength in his grip tightening. Then, just as suddenly, he let go.

Relief washed over her—yet beneath it, a strange, unexpected pang of loss. But before she could process it, his hand moved behind her neck. His face leaned in.

Instinctively, she turned her head away. But it was too late. She felt his lips press against the nape of her neck, warm and certain. His tongue flicked out, tracing a slow, burning path along her skin.

“Sarah Jin…”

His arm wrapped around her shoulder, pulling her close with firm pressure.

“David Seung… we shouldn't—”

“Why not? What's wrong?”

“Obviously—”

But when she turned to speak, her words were cut off. His lips crashed against hers, silencing her protest.

His tongue surged forward, relentless, ignoring the resistance of her tightly closed mouth. He sucked at her lower lip, then bit it gently—just enough to make her gasp—and in that instant, his tongue plunged inside.

A searing kiss. Sarah Jin was overwhelmed. Her own tongue, helpless, was teased and dominated by his. The kiss went on and on—far longer than any she'd ever known. And as it did, she remembered her first kiss with Michael Min—six months into their relationship. It had lasted six seconds. This had already been thirty minutes.

Another thirty minutes passed. Only half an hour, yet Sarah Jin's lips were now fully open, instinctively sucking on the tongue invading her mouth. Occasionally, she even found her own tongue slipping into his, curling around his, mimicking his rhythm.

“You're a passionate woman, Sarah Jin.”

Even after that long, fervent kiss, David Seung lingered, brushing his lips lightly against hers, tasting her, savoring her. Each time his mouth touched hers, Sarah Jin found herself closing her eyes without meaning to.

“I don't feel regret anymore…”

When Sarah Jin looked at him, confused—What does that mean?—he didn't answer. Instead, he pressed his lips to hers once more.

Kiss… regret…

But Sarah Jin was beginning to understand.

She felt his hand on her knee. Softly, it cupped her flesh, then began to glide upward. Instinctively, she pressed her legs together—but that was all she could do. And even that small resistance was easily overcome. His hand slid higher, caressing her inner thigh.

Ah… I didn't wear underwear today…

She felt it—the place where her stockings ended, just mid-thigh. His fingers touched her bare skin there, and the sensation sent a jolt through her.

“So soft… your skin, Sarah Jin…”

Instinctively, she lowered her head, embarrassed. But then she felt his breath—hot, electric—against her ear. A moan rose in her throat, and she clenched her lips shut to suppress it. But David Seung didn't stop. His fingers gently stroked the sensitive inner flesh above her stockings, and Sarah Jin, overwhelmed by the heat in her ear and the softness of his touch on her thigh, could think of nothing. Her body trembled, shaken by a powerful, unfamiliar pleasure.

“I don't think there's any regret between us now…”

His deep, soothing whisper in her ear was followed by the unmistakable sensation of his hand covering her most private place—over her panties. Her entire body stiffened.

“You're wet…”

He gently pulled her panties aside, and one finger slipped inside, parting her folds. Sarah Jin burned with shame.

It's been a year…

It had been a year since she'd met Michael Min. Their first sex had come only three months ago, after endless hesitation, after setting the wedding date. And now, in less than an hour, she had opened herself to Michael Min's friend.

“You're so hot… so soft… and so wet…”

His low voice whispered against her ear. She couldn't understand it. But one thing was clear: a fierce, overwhelming excitement. Pleasure. And a strange, undeniable sense of rightness.

His hand slipped out from under her skirt. Another thirty minutes had passed. Her pussy, soaked from his teasing, had dampened not just her panties but her skirt as well. Finally catching her breath, she became aware that her blouse was slowly opening. Every button of her blouse—hidden beneath her jacket—had been undone. Cool autumn air brushed against her bare skin.

“What beautiful breasts…”

She felt her bra being pushed up, her chest exposed. But as his tongue swirled in her ear, she closed her eyes again. Moments later, she felt her breast pulled into his mouth, and she had to bite her lips shut to keep from crying out.

David Seung sucked greedily at Sarah Jin's breasts—full for a Korean woman, yet still firm and youthful, the body of a woman in her late twenties. With his other hand, he slipped back under her skirt, past the waistband of her small panties, and buried his fingers deep in the thick, lush hair covering her pussy.

She couldn't comprehend this. Her fiancé, to whom she'd given her body after a year… and yet to his friend, she'd surrendered everything in less than an hour. And here, in his arms, she was feeling pleasure and arousal unlike anything she'd ever known.

What shocked her most was that none of this felt awkward. Of course, there was shame, embarrassment—but no desire to stop him. No resistance in her heart. In fact, she realized she was sinking deeper and deeper into the sensations he gave her, into the excitement he stirred.

His touch was relentless. Patient. As if he knew exactly how a woman's body and mind worked—whether from patience or intuition, he caressed her endlessly, gently, without rushing.

At some point, her skirt had been pushed down, and beneath it, she was completely naked. Her chest, freed from the bra, stood bare and full, worshipped by his hands and mouth.

“Ah…”

One of his fingers, still gently stroking her wet folds, suddenly slipped inside her. Sarah Jin couldn't suppress the moan that escaped her lips.

“So hot…”

His whisper sent shivers down her spine. Her legs, which she'd tried to close, went slack, and she welcomed his finger deep inside her.

“Now feel it…”

The tip of his finger pressed firmly against her clit. A shockwave of pleasure surged through her body. Without thinking, she wrapped both arms around his neck. As his lips covered hers again and his tongue plunged into her mouth, she sucked fiercely on it, matching his intensity.

Soon, her body began to tremble. His finger worked magic, driving her shaking to its peak, and as she sucked harder on his tongue, she felt an unimaginable surge of sensation flood through her.

“Good, isn't it?”

His breath warmed her ear, but a deep languor had settled over her body. Weakly, she nodded.

He wouldn't let her rest.

“Now it's your turn.”

He unbuttoned his pants, unzipped them, and pushed them down. His cock sprang up, hard and thick like a coiled spring.

“Touch it… it's because of you…”

He took her hand and guided it to his shaft. Sarah Jin gasped as her fingers closed around him.

His cock. She'd had sex with her fiancé, but she'd never touched a man's cock like this before. She flinched in surprise—but he didn't let her pull away. After a moment, a strange curiosity began to stir within her.

So thick she couldn't wrap her hand fully around it. So hard it felt like steel beneath velvet. The weight of it in her palm slowly erased any hesitation, pulling her deeper into a thrilling, intoxicating excitement.

“Touch it… feel it…”

Slowly, Sarah Jin began to stroke him. The contrast was astonishing—so soft on the surface, yet so powerfully rigid beneath.

I must be crazy.

Suddenly, she wondered how this could possibly fit inside her—and was horrified by her own thoughts.

A man she'd just met. Her fiancé's friend. Less than two hours ago, she'd been an ordinary woman on her way home. Now, she was imagining letting this man's cock into her body. It wasn't just surprising—it was terrifying. And yet, the sheer force of his presence, the raw excitement he stirred, couldn't be denied. She was falling for him, fast.

“Will you suck it?”

Sarah Jin jumped at the words. Suck his cock? But moments later, it was in her mouth. She was bent over the plush seat of the luxury sedan, taking him deep with her lips.

“Yes… move your tongue like that… lick the head… and use your hand to gently massage the base…”

Mindlessly, she swirled her tongue around his cock, sucking and licking as it filled her mouth. His hand returned to her pussy, stroking her slowly, while occasionally reaching up to squeeze her bare, upright breasts.

“Good… now take it deeper… use your lower lip…”

As he spoke, Sarah Jin moved toward him like she was hypnotized. Slowly, she positioned herself over his cock, lowered her hips, and guided it to her entrance.

“Ah… ugh…”

The sensation was overwhelming. Even though she was soaked with arousal, his cock—so thick, so hard—felt like it would split her open. But she gritted her teeth, endured the stretch, and slowly lowered herself. Then, suddenly, she felt the tip of him touch something deep inside her.

“Ah… better than I imagined… so good…”

David Seung groaned. He could feel it too—her body was even tighter, more perfect than he'd dreamed. His cock gripped by her heat, he gently massaged her firm, round ass with both hands. Pulling her waist closer, he drew one of her large, taut breasts into his mouth, sucking her small, pretty nipple.

“Move slowly… pleasure me with your body…”

Sarah Jin realized the confined space of the car actually intensified the sensation—the restricted movement made every shift more powerful. Guided by the warmth of his hands on her ass, she slowly pushed up with her knees, lifting her hips.

The friction inside her pussy sent waves of pleasure through her. She felt a perfect unity, a connection she'd never known before.

I must be insane…

She couldn't believe it—here she was, riding this man's cock, deep inside her, moving with him. Something she'd never even imagined in her life.

“Ah… I can't hold back… your body… it's incredible…”

David Seung wrapped his arms tightly around her waist.

“Don't move… I can't take any more…”

She looked down, met his eyes.

“I'm going to come.”

He spoke while sucking her breast, staring into her eyes. A sudden wave of shyness washed over her. She knew exactly what he meant—and for a moment, she hesitated.

“Feel it… I'm going to fill you with everything…”

But then, a fierce desire surged within her—to take all of him, completely. Without another thought, she wrapped her arms around his neck and pulled him close.

“Ah…”

His arms tightened around her. And then she felt it—his cock twitched violently inside her. A moment later, warmth flooded her lower abdomen. An overwhelming rush of excitement crashed over her. She clung to him, trembling, her entire body quivering with sensation.

“You're mine now…”

After the storm passed and he caught his breath, David Seung slowly sucked her breast as he spoke.

Sarah Jin felt fear. Shame. Uncertainty about the future. A deep unease settled in her chest. And yet, no matter how hard she tried, it all felt like a dream. He had definitely come—she could still feel it inside her—but his cock remained hard, still buried deep.

What will happen to me now?

Slowly, she embraced the man rising above her, tightening her pussy around his still-firm cock. And once again, she began to fall—into ecstasy, into surrender, into him.
