A/N: And now back to our normal YJ/GE pairing with...a threesome. One of my awesome readers/reviewers gave me this suggestion, and I ran with it. Not sure if this is what you had in mind, but...here it is. There will definitely be more of a bad girl Ga Eul in this one.

This first part is just a teaser, so don't expect any smut. I promise, there will be plenty of it, and then some, in Part Two.

"What about that one?" Yi Jeong asked.

"Which one?" Ga Eul answered.

"The one at the bar in the gold dress. With her hair pinned up."

"Who wears their hair like that at a club? It looks like she's going to an office party."

"So...no then?"

"She looks...a bit stiff," Ga Eul elaborated.

"You were a bit stiff when I met you. Are you doubting my ability to loosen her up?" Yi Jeong cocked an eyebrow.

"I'm doubting her ability to loosen up, period," Ga Eul replied.

"Ouch. Okay, moving on then." Yi Jeong downed the last of his beer and opened another bottle. He offered some to Ga Eul, who shook her head.

"I'm fine with my girly drink, thanks. It tastes like a smoothie but with, you know, sugar and alcohol." She stirred the creamy, peachy mixture with her straw.

"One day, Ga Eul-yang." Wrapping his arm around her shoulders, he pulled her closer to him in the club's massive black VIP booth they currently occupied, alone.

"Keep dreaming."

"Ah, but you like my dreams. They led you here, didn't they?"

"If by here, you mean fulfilling your weird sex fantasies—"

"I have perfectly normal fantasies, thank you. And you enjoy this too. Otherwise you wouldn't be doing it. A fifth time." He grinned through the last sentence, and she rolled her eyes at him and laid her head on his shoulder. She stroked his leg with her nails, slowly working up to his thigh. If she kept edging her way to his crotch like that, he might forget about picking up anyone else and take her home instead. He could rip off her scoop neck burgundy dress in five seconds flat and have his black suit off in another ten.

He knew what she would say. What a waste of money spent on a hotel room they didn't use.

Like that amount of money meant anything to him.

He shook his head as he took another swig of beer, surveying the area around them for newcomers. Part of Ga Eul would always be a commoner.

But she was his commoner, and that was all that mattered.

It had been three months or so since he admitted one of his biggest fantasies was having a threesome with her and another girl—any girl.

Surprisingly, she'd agreed to try it without much hesitation, even admitting that one of her fantasies was doing it with a girl.

Now that had given him something to fantasize about.

Three Months Ago

"We both have to agree on the girl," Ga Eul said, fiddling with the part of Yi Jeong's navy blue tie that hung at her eye level. He was sitting on the couch while she laid across it with her head in his lap as they discussed putting his fantasy into action. Ga Eul, ever the planner, had decided to list out some ground rules.

"Obviously," he replied, gazing down at her. She still wore her outfit from work, a gray pencil skirt and a long sleeve pink pleated blouse that covered too much, yet somehow managed to make her look sexier because of it. "And she has to agree to fuck both of us...Or she can just fuck you. I'm okay with watching that too."

"Of course you are, Sunbae. But that's not the point of your fantasy, is it?" Ga Eul responded wryly.

"I mean, that's kind of another fantasy, but..." He cleared his throat. "Anyway, go on."

"Next rule." Ga Eul rubbed the silk of his tie against her pink glossy lips. "Check for STD's."

"Check." He twirled a loose strand of her hair.

"Use condoms."

"Mmhm." He tucked the loose hair back in place so that it framed her face smoothly.

"If anyone isn't comfortable with something, we stop...I mean, there isn't anything specific I don't want you to do to the other girl, at least in theory, but..."

"Except fucking her without a condom."

She glanced shyly to the side. Bit down on the end of his tie.

"Yeah, that," she said around the tie in her mouth. "But you can fuck me without a condom."

Yi Jeong smirked.

"Noted. Well, I think that covers the most important things."

"Yes, but...isn't there some stipulation you'd like to make?" She removed the tie momentarily.

"Not really. Look, Ga Eul-yang, I know you're a teacher, and teachers like rules, but the thing is...generally life is more fun without them."

"Well...I guess that's true." She stared up into his eyes and bobbed her head a bit.

"Let's just make a general pact to communicate about everything."

More head bobbing. She twisted the tie between her fingertips.

"But I still feel like there should be one more rule. I mean...leaving it at four rules feels weird. I like things that come in fives. Or threes. Or sevens or something."

"Then I think that's a sign that you're going to enjoy a threesome very much."

She arched her eyebrow.

"But definitely not a foursome." She slipped the tie back in her mouth.

"No, no, definitely not. We have to stick with the odd numbers for your sanity. Say, are you going to give me my tie back, or are you going to eat it?"

"I'm going to eat it." Grinning perversely, she stuck her wet, pink tongue out and licked up the portion of the tie she held in her hand.

He felt his cock twitch in his trousers. The pressure of her head on his groin wasn't helping his growing erection any.

He found himself unable to tear his eyes away as she licked up the tie again and sucked the tip of it, leaving a huge wet spot noticeably darker than the rest of the tie.

"Fuck you," he whispered.

"Please do," she whispered back.

Present

Theirs was still primarily a monogamous relationship, albeit with an added kink. But that was fine with Yi Jeong, who had expected to only be with Ga Eul for the rest of his life. Obviously, that would be great in itself, but this was the icing on the proverbial cake.

And it wasn't vanilla icing, either.

"How about her?"

"She's nice."

"Nice?" Yi Jeong repeated. "She looks like Lee Hyori with a better ass."

"Actually, Sunbae, I think that is Lee Hyori."

"What?"

"Kidding." Ga Eul laughed. "You looked like were you about to fly across the table."

Yi Jeong gave her an accusatory frown.

"Don't tease me like that. She was on my list until you made me take her off and replace her with Scarlett Johansson." He was referring to the list they had of five people each they were allowed to cheat on each other with.

"We agreed it had to be people we were highly unlikely to meet." She poked his arm. "Obviously you couldn't have people from Korea on your list."

"Then why do you get to have Koreans? Oh, right, right. Because you're a poor commoner. Only you're not because you're married to me. Doesn't that defeat your argument?"

"Still, you have to admit, the likelihood of you getting to sleep with Lee Hyori is much greater than me getting to make out with Kim Beom."

"Oh, just making out, huh?"

"I wouldn't go all the way."

"Uh-huh."

"No, no. See, I have standards." She sipped her drink through her straw and stared coyly up at him.

"Says the girl picking up women with her husband at a nightclub."

Ga Eul shrugged.

"I'm being open-minded." She slouched down a little, leaning against him. "Or maybe I secretly enjoy the fact that the other woman has to leave eventually, but I get to keep you."

"Oh, I see. You think it shows how much power you have over me." Bending his neck, he looked straight down at her face, letting his gaze wander further to the cleavage exposed by the plunging neckline of her dress.

"Well, it does." She batted her eyelashes.

"You're not that powerful," he said, his lips betraying him, automatically curving in a smile.

"Yes, I am."

"Mmmm...no, you're not."

"Yes, I am. If I'm not, then why am I picking out women for you?"

"For us, you mean. And I don't know why I'm letting you. The one in the gold dress. We should have gone with her. Now she's leaving. Look, there she goes."

"She wasn't the one."

"Wasn't the—we're not picking out a puppy."

"She wasn't the one. She wasn't—"

"We've been here an hour, and nobody's been 'the one.'"

"The problem with you is you want to settle for the first thing that comes along."

"Settle? So Yi Jeong does not set—"

"When you could be picking up someone truly amazing, like me."

"Ga Eul-yang, are you trying to find us a hookup or me a second wife?"

"I'm just saying, some people's personalities get on my nerves."

"So shut them up. Put something over their mouth. Something that rhymes with blunt."

"Haha. Very funny."

"I'm just saying. I would like it."

"Fine. What about the lady over there in the blue dress?"

"Standing next to the guy with the martini?"

"Yeah."

"Uh, well...I'd say she's a seven."

"A seven? But she's so pretty."

"She's a seven. But the woman next to her in the black dress—"

"Ten," Ga Eul finished.

"I was gonna say nine...but if you think so."

"You wanna know what I really think, Sunbae?"

"What?"

"I bet I can bring her over here faster than you can."

"You're on."

A/N: Hope you enjoyed this so far! This is totally off-topic, and not smut or YJ/GE-related, but I just posted a one-shot Orange Marmalade (2015 K-Drama) fanfic that I wrote a while back for fun. It's called "Promises, Promises," and it's under my profile. So if you like that drama, or if you like unresolved romantic tension, or vampire/human romance, or my writing style, I would love it if you checked it out. It's short and sweet. 'Kay, bye :)
