The Second Day: Enjoying the Girlfriend's Betrayal

On the second day ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠of the business trip, the boyfriend who enjoyed his girlfriend's betrayal had a bit more free time, so he spent it wandering around with Lee Se-jeong. They walked along the beach together and had lunch at a restaurant. No matter where they went, they drew everyone's attention. Both Min-hoo and Lee Se-jeong had above-average looks, so the stares were only natural.

"Director," Lee Se-jeong said, clinging tightly to his arm.

"What?"

"Um… can I call you Oppa today?"

Lee Se-jeong smiled bashfully, still looking beautiful.

"It might stick if you're not careful."

"I'll be really careful. Just for today, okay? I really want it to feel like a real date."

"A date behind your boyfriend's back, huh."

"You're the one playing around with that girlfriend behind your little sister's back, Oppa."

"I never gave permission for that."

"Hiiing. Please?"

"Fine, whatever."

Lee Se-jeong's aegyo seemed to carry real power. She pressed his shoulder firmly against her chest.

"Thank you, Oppa."

"People are watching."

"Let them look. I'm yours anyway, Oppa."

Walking along the beach like lovers gave him a warm, fuzzy feeling. Even just sitting on a bench for a moment, he could feel countless eyes on them.

"Oppa, everyone's staring at us."

"Guess we should head somewhere quieter?"

Wherever he went with Lee Se-jeong, Min-hoo sent photos to Kim Ki-woo. Shots of her walking on the beach, having coffee at a café—everything.

'Time to give him a little shock.'

As they walked, they came across a somewhat secluded spot.

"Se-jeong, want to go over there?"

"You look suspicious."

"Hm?"

"You're planning to make me do something naughty, aren't you?"

"You know me too well. As expected of my little secretary."

Lee Se-jeong chuckled and took his hand first, leading the way.

"Let's go. I've been wanting to see your cock anyway."

"Really?"

"You know what? Most women get turned on just looking at your face, Oppa."

"That much?"

"They think, 'I wish that guy would fuck me.'"

"Even if it's rape?"

"More women wouldn't allow it, but some would. That's what I'm saying."

"So you're in heat right now?"

"Your face has been looking way too handsome since earlier. It's driving me crazy. And your cock… it's ridiculously handsome too."

Smiling prettily, Lee Se-jeong hid between the rocks and immediately unzipped his pants. She skillfully pulled out his cock and began moving her tongue with both hands wrapped around it.

Lick. Lick.

"Haa… I really love this cock."

"Se-jeong, I'm taking a photo."

"Why? Does my face while sucking cock look lewd?"

"Yeah. Extremely."

"If it's you, Oppa, I don't mind. I'll just cover my eyes a little."

Click. Click.

He sent the photos to Kim Ki-woo.

"Se-jeong says my cock tastes amazing."

"Want me to send a short video?"

While Lee Se-jeong sucked on his glans and rolled her tongue in a frenzy, he recorded only about ten seconds of video. He deliberately kept it short for later.

"Se-jeong's sucking it so deliciously."

This time, the reply came slower. A quick search showed Kim Ki-woo had run straight to the bathroom and started jerking off to the video.

'Crazy bastard.'

Whether it felt that good, Min-hoo couldn't understand that kind of fetish, but since he could enjoy it himself, it was fine.

Teasing Kim Ki-woo was fun too. It would be twice as entertaining to mock him while fucking Se-jeong right in front of him later.

Slurp— Lick—

Lee Se-jeong sucked his cock more greedily, craving his semen.

"Oppa… cum for me. In my mouth."

"Talking with my cock in your mouth makes it more stimulating."

"That's why I'm doing it."

"Fine. I'll cum in your mouth, so don't swallow. Collect it and show me."

"Yeees."

Slurp— ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠Suck—

Her wet mouth wrapped around him tightly. She persistently attacked his glans, squeezing out his semen. The outdoor blowjob made his excitement rise quickly.

"I'm cumming."

Spurt! Spurt!

Following his instructions, Lee Se-jeong collected a thick load in her mouth. She opened wide to show it.

"Wait a sec."

Click—

He took a photo and sent it to Kim Ki-woo.

This time, no reply came. Even to Min-hoo, the composition looked extremely lewd. How stimulating would the sight of pretty Lee Se-jeong's face and mouth full of his semen be for Kim Ki-woo?

Kim Ki-woo was actually pretty cute.

"Who are you texting so much with?"

"Work stuff. Ki-woo's contacting me."

"He must be busy. A lot."

"Yeah."

Slurp—

She cleaned his cock on her own and neatly tucked it back into his pants.

"You're not going to fuck me here?"

"If I do it once… I don't think I'll be able to stop. So I'm holding back."

"You could just do it."

"I want to enjoy the date more right now."

"Alright. Tell me everything you want to do."

"Let's go bungee jumping together!"

"Ah, that's a bit…"

He texted Kim Ki-woo.

Instead of bungee jumping, they spent time on banana boats and other leisure activities.

"Out of all the couples I've seen, you two seem to match the best."

At the boat staff's words, Lee Se-jeong proudly pulled Min-hoo closer by the shoulder.

"Hehe. Thank you."

Lee Se-jeong seemed genuinely happy to act like lovers with him. Whenever people misunderstood them that way, she smiled brightly and enjoyed it.

After lunch and an afternoon business meeting, they returned to the hotel.

"Oppa, they have a nice hotel lounge here. Let's have a quiet drink there."

"Shall we?"

"Yes! Let's go!"

Lee Se-jeong seemed eager to enjoy more time with him, showing off her tireless stamina. Even there, she used him to fill her desire for attention. In front of the beautiful female bartender, she deliberately bragged.

"My Oppa is really handsome, right?"

"Yes. He's the most handsome male guest I've seen recently."

"Thank you."

The bartender was quite pretty too, but definitely not on Lee Se-jeong's level. Min-hoo's standards had clearly risen. In the past, he might have wanted to sleep with someone like her, but now he felt nothing.

"……"

Meanwhile, the bartender couldn't take her eyes off him. She kept glancing over, looking like she'd come up to his room the moment he gave her the number.

'Maybe I'll try a one-night stand someday.'

Come to think of it, he'd never had that experience. Picking up a pretty girl at a club or entertainment district and sleeping with her might feel novel.

'There might be gems there too.'

Using his search ability, he might meet the best women.

After enjoying a moderate amount of alcohol, they returned to the room. He laid Lee Se-jeong, fresh from the shower, straight onto the bed.

"Spread your pussy with your hands."

"Are you taking photos of that too?"

"Yeah."

"You're taking a lot today."

"For my personal collection."

"Really? You're not showing it to anyone, right?"

"I hate having what's mine taken away the most."

"Hehehe. Okay."

I'll show it to your boyfriend. He took several photos of her smiling prettily while spreading her pussy.

Click. Click.

This should get Ki-woo excited again.

Min-hoo felt excited too. Just exchanging texts like this amplified the pleasure. He wanted to enjoy this moment even more. So he took a photo while pounding her in missionary position and sent it, then another of her riding on top of him, smiling and rotating her hips.

The call came in immediately, as if he'd been waiting. Lee Se-jeong, who had been happily rotating her hips, covered herself when she saw the phone.

"Who is it?"

"It's… Oppa. Haa…"

"Answer it."

"I want to focus on your cock…"

"Answer it. It might be something important."

"You're doing this because you want to feel the sense of betrayal, right?"

Min-hoo ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠answered with a smile.

"Oppa, you're such a pervert too."

"Call me Director now. You might slip up otherwise."

"That's a shame. Yes, I'll do that."

Click—

"Yeah, Oppa. What's up? Haa…"

-Uh, Se-jeong. Did you eat dinner?

"Yeah. With the Director."

At his mouthed instruction to put it on speaker, she pressed the button. Squish. Squish. Squelch. Squelch. Her hips, which had been moving vigorously, slowed a little but the wet sounds still continued.

-Then what are you doing now?

"Right now, um… just exercising?"

-What kind of exercise?

"I ate a lot today… haa… so just some bodyweight exercises?"

Kim Ki-woo already knew Lee Se-jeong was lying. That would create a sense of betrayal, which would turn him on even more.

-You must've eaten a lot. So you're not eating now?

"Uh-huh. I told you I'm exercising."

-That's why I can hear moaning.

"Right. Haa…"

To make it more stimulating, Min-hoo started thrusting his hips.

"Hup!?"

Even when she tried to hold back her moans with one hand over her mouth, every time he thrust hard—Thrust! Squelch! Squelch!—it became difficult to stay quiet.

"Haa! Haaah!"

-Se-jeong? What's wrong? Are you hurt?

Kim Ki-woo was acting well too. He was probably jerking off furiously while on the call.

"N-no. I'm fine. Haa. Oppa, I'm tired so—"

-Just a little. Let's talk a little longer.

"I'm tired though… hiih!?"

Min-hoo was getting incredibly turned on too. Fucking her behind Kim Ki-woo's back had been exciting, but this was a different kind of stimulation.

-So what is the Director doing?

"I-I don't know. Haa. I don't know. Haaah!"

-If the exercise is hard, take breaks while doing it, Se-jeong.

"I-I'm fine."

Lee Se-jeong pinched his nipple with her free hand. It was a signal to ease up. She was anxious, afraid they'd really get caught.

'Like I'd stop.'

Thrust! Thrust!

He grabbed her hips and thrust properly. Since Kim Ki-woo could hear anyway, there was nothing to lose, but Lee Se-jeong didn't know that. She was genuinely anxious and didn't know what to do. That turned him on immensely.

"Haa! Haa! Haaah! O-Oppa! I'm hanging up now!"

Click—

She hung up first and cried out.

"W-why? We could've really gotten caught!"

"Ki-woo's too dense to notice. It's fine."

"He definitely heard my moans just now… haa! All of them. Haa! Haaah!"

That was exactly what Min-hoo wanted, so of course. Feeling the need to release his rising excitement, he thrust his hips properly.

Thrust! Thrust! Squelch—

"Haa! Haa!"

"I'm cumming!"

Spurt! Spurt! Spurt!

"Haaahhhhh!"

Min-hoo and Lee Se-jeong reached climax together. Clinging to him and sobbing, Lee Se-jeong panted heavily.

"It was hotter because you thought Ki-woo might've caught us, right?"

"Haa… haa… I'm going crazy from the anxiety. Really. If we get caught, how am I supposed to keep working at the company?"

"You're more anxious about not seeing me, aren't you?"

"That's right. So don't do that next time."

"I'll try."

Next time, he'd have to stage an even more stimulating act. When they got back, he'd have to invite Kim Ki-woo and Lee Se-jeong to his house.
