Chapter 1 — My Friend and the 3S - Part One (1)

"Take care."
"Yeah, thanks for coming."

It was Jaeseok's wedding day—the last of our high school friends to marry. Ever since he'd taken charge of our group's reunion committee, handling all the tedious and thankless tasks, everyone showed up in full force.

Our friends' weddings always ended with messy after-parties—so messy, in fact, that three couples had actually gotten together because of them.

But this time, Jaeseok's farewell to bachelorhood seemed destined to end not with wild revelry, but with a quiet dinner among married couples.

"Daniel Park, wait up. Let's go together."

Just as my wife Emma Kang and I were heading toward the after-party venue, David Song came running after us.

"Damn it, kid—you just gonna run off like that?"

David Song was panting heavily as he caught up. But his wife wasn't with him.

"Where's Sarah Seo…?"

"We split up. Me and her."

"What? Why?"

My wife Emma Kang stared at him, visibly shocked.

"Well… that's how it is. Please… don't ask anymore."

David Song let out a weary sigh, as if resigned to fate, then walked ahead of us.

But from the back, his posture screamed how much he'd been suffering all along.

Let me briefly explain my relationship with David Song.

We'd been inseparable since middle school, all the way through high school.

But more importantly—we were close friends since school.

For those unfamiliar with the term, let me make it clear:

Sarah Seo, David Song's wife, and I had never dated before marriage, but we were sex partners who enjoyed each other.

And David Song? He'd been in a long-term affair with my wife Emma Kang.

All four of us knew about it. We'd grown tired, bored with our own partners, worn down by familiarity.

Around that time, David Song drifted from Emma Kang, and I stopped finding satisfaction in my encounters with Sarah Seo. Both of us started looking for someone new.

Unable to stand it any longer, I gathered the other three and made what I thought would be an impossible proposal.

I suggested that I marry Emma Kang, David Song marry Sarah Seo, and we remain faithful to our spouses—until we had two children. After that, we'd be free to enjoy each other again.

Honestly, I expected resistance. But surprisingly, they all agreed enthusiastically.

So I married Emma Kang. David Song married Sarah Seo.

But after the weddings, life didn't go as planned.

We got squeezed by time. Crushed by money. And slowly, my original proposal began to fade into nothing.

Now, learning that David Song had divorced Sarah Seo—Emma Kang and I were stunned.

"Hey, man. What the hell happened?"

No sooner had we arrived at the after-party than I cornered him. Emma Kang kept glancing at him, clearly curious.

"She cheated. Ran off with some other guy. Fucking bitch—I was giving her cock two or three times a day!"

"At least you're free now."

"Man, when did you two split? Why didn't you tell us?"

"Let it go. Don't ask anymore. It's painful… Daniel Park."

David Song's voice cracked with exhaustion, as if all his suffering was packed into that single sentence.

"Daniel Park. Sarah Seo will be fine. Do you really think she's some ordinary woman?"

That night, we left David Song behind, walking home in silence.

Emma Kang and I didn't speak a word on the way back.

I knew she must be feeling conflicted.

"Emma Kang… do you still think about David Song?"

She sat at her dressing table, slathering her face with thick cream, staring at me through the mirror.

"What kind of question is that?"

"Just… wondering."

"Wondering what? What exactly do you want to know?"

Her sharp tone surprised me.

"Fine, forget it. Why get so angry? Huh?"

I was getting angry too.

Not at her—but at myself. At the fact that my closest friend had fallen apart like this.

That night, Emma Kang slept in the small room with our son.

The next night. And the night after that.

"Emma Kang… I'm sorry. I feel like… it's all my fault. What happened to David Song."

I was the first to surrender.

"I feel bad too, that David Song got divorced. But blaming me for connecting him to us? That's what I don't understand."

"I didn't mean to blame you. Do you remember? The proposal—two kids, then free sex?"

"You were the one who agreed to it… don't you remember?"

"I did… back then…"

"Can't you just see it as… the timing changed? Seeing him like that, shoulders slumped… it broke my heart."

"What the hell are you saying? You want me to—?"

"Yeah, I'm fine with it. Why don't you… comfort him a little?"

"No. I don't want to."

She clenched her jaw, refusing.

"Why not?"

"This isn't free sex. It's one-sided. It's just… sex."

"But I'm okay with it."

Silence stretched between us.

"Emma Kang… truth is, I've been really into wife-sharing arrangement lately."

"What's wife-sharing arrangement?"

"Let's just say… inviting one man to join us in bed. It's kind of like swinging. You once said you'd try it if the chance came."

"If it's David Song… it'd be good for all of us. For him too."

"If you hate wife-sharing arrangement, we can just meet alone. I don't care."

"Let me think about it."

"Yeah. Don't rush. Take your time."

That night, Emma Kang's pussy was soaked with arousal.

"Imagine my cock is David Song's cock. Hahh… hahh…"

I pulled my cock almost all the way out, then slammed it back in, pistoning deep into her wetness.

"Thud."

The sound of my hips smacking against her ass felt especially fresh tonight.

"Honey… yes… so good… I'm going crazy."

"Don't call me honey. Call me… David Song."

"Uh… uh… uh…"

"You don't like it? Still hate it?"

I pounded her valley savagely, fast and hard.

"Ahhhhhh… too good…"

"Say it… call me David Song…"

"Ah… David Song… it's too good…"

Hearing her say his name sent a jolt through me—shock, then a sharp thrill of arousal.

"Emma Kang… Emma Kang… ughh…"

That night, I emptied an enormous load deep inside her trembling depths.
