Moonlight Bar & Lounge, 11:42 PM

As the two of you peered up at the establishment’s buzzing, neon lights, Siyeon had to make a conscious effort to prevent her hand from dropping too low on your ass. 

She’d made a promise to you – back at the hotel and in her post-orgasm haze – that she would be on her best behavior while you were out celebrating as a way of repaying you. 

You, in return, vowed to let her do anything she wanted to you once you were back in private, so long as she kept things tame and didn’t go back on her word in the meantime. 

And, for what it was worth, she was really giving it her all.

But you looked absolutely divine in your formal outfit – radiant with a sultry undertone, capable of leaving her transfixed. It drove her crazy to know that hidden away beneath it, tucked out of view from prying eyes, your skin was painted with all of her marks. Splashes of color, hues of red and purple growing darker with time – her own personal claims on you. With how hard it had been for her to keep her mouth off of you earlier, she was surprised you had any skin left unmarked at all. 

“Two more hours, Singnie. Think you can handle it?” You asked, glancing at her as you both approached the door. 

She opened it, sending you a confident look all the while. “Of course I can.”

You hummed, unconvinced. “We’ll see about that.” 

When you passed her, a smirk pulled at the corner of your lips. Her gaze had fallen to your ass, again, watching its every move in silent admiration as she trailed behind you like a puppy. 

—

The reviews you’d read, though stellar, had failed to prepare you for just how nice the place was. Its intimate ambience beckoned you in at once, extending an easy-going hand, inviting you to look around and see for yourself everything that it had to offer. 

Things were darkened inside, creating an aura of sensuality and mystery despite the openness of the layout. Hues of black and blue accented the furniture and decorations, in line with the established theme of intrigue. Large skylights were centered in the ceiling, allowing plenty of moonlight in to do as it so pleased. 

A dance floor called from the far side of the room, comfortably crowded and taking up about half of the venue. Couches and chairs were situated around tables on the other side, strategically dotting the available area so as to award parties their privacy. 

The bar was large, stretching out far and wide as it stood ready to greet you upon your arrival. A busy bartender met Siyeon’s eye when he glanced up, vigorously shaking a drink. 

“Welcome, ladies!” He smiled warmly. “It’s great to have you tonight.”

You thanked him with a smile as well, and Siyeon extended the same courtesy. Her arm fell to your waist again mindlessly – completely out of habit as she turned to survey everything. 

“How about we get a table first?” She suggested, subtly motioning towards them with her head. “Then we can dance for a bit, if you’d like.”

“Sure, babe. That sounds perfect.”

One Hour Later

Put simply, Siyeon seemed to be out to get you. 

Though she was your girlfriend, the love of your life, your protector – something truly sadistic shined in her dark eyes as she peered at you from the other side of the table, smirking around the rim of her glass. 

She watched you squirm in your seat a little, feigning oblivion as her foot traveled up your calf, teasing. 

Somewhere between her first and second rounds of wine she had undone the top few buttons of her blouse, and the seductive way she pressed closer to the table, arms crossed just below her chest, put her cleavage on full display. The edge of her bra was visible, too, but that was a detail likely only perceptible to you, considering your proximity and inability to focus on anything else. 

Every bit of her prior innocence was gone without a trace, eclipsed by the desire she felt, which was becoming harder and harder to maintain a grip on. 

The alcohol in your system was weakening your inhibitions, too; coaxing them to vanish as her charm worked its magic, promising release for you the second you asked for it. It showed in her eyes – which shamelessly drank in the sight of you – and the subtle bite of her lip. She appeared collected, but you knew that in reality she was far from it.

You downed your last bit of wine in an effort to distract yourself. 

As you lowered your glass, the ring on your finger shimmered, catching the attention of one of the club’s cycling lights. Siyeon looked at it proudly; it was the promise ring that she had given you this morning.

Wordlessly she reached forward, palm upturned. 

The musing, pleased smile on her lips would be your demise. You were sure of it. 

But even still, you extended your hand and placed it in hers, following her unspoken request. She held it close, rubbing her thumb across the back of it in soothing, easy strokes. 

Nothing made her happier than knowing you were hers.

“Ready to dance?” She asked, trying not to sound too eager. The thought of having your body against hers was ruining her in all the best kinds of ways. 

She was fiending for it.

You took a deep breath, steadying yourself for what was to come. She knew that asking was unnecessary, but she took pleasure in seeing you squirm. 

“Sure.” You swallowed. 

Happily, she finished off her wine. 

Leaving behind your empty glasses and appetizer plates, she stood up and led you to the dance floor.

30 Minutes Until Promise Is Completed

The DJ was a true professional at his craft, and you decided at once that he deserved the biggest raise imaginable.

…do DJs get raises?

Regardless, he was owed one. 

His choices of song, paired with the seamless transitions and mixes that he conducted, set the mood of the lounge and kept everyone's energy high. A strong bassline carried throughout the place, thrumming consistently and so powerfully you felt it in your very being. 

Like an undercurrent, it flowed around you. Pushing and pulling, leading you out just to lure you back in again.

Siyeon moved in time with you, hanging onto the rhythm as you let loose. She kissed you occasionally, swept up in the heat of the moment and unable to resist your beauty. Her hands wandered, impossible to control as they made it their mission to tempt you. 

The couples around you all shared that sentiment as well – turning the air thick with sexual tension. 

Some grinded. Others groped. It was a plethora of positions and strides, all writhing and searching for relief – a statement piece on the human condition, plucked straight from a movie scene. From your place within it, amongst the welcome chaos, you could only imagine what a sight it was to behold from an outside perspective. 

A sudden buzzing tethered you back down to Earth, garnering your attention. It came from Siyeon’s front pocket, which was conveniently nestled right between your thighs. 

The contact made you tense at first, not expecting it, but it felt good. More than good, even. And far better than you cared to admit, considering you wanted to hold onto some of your pride. 

She felt it, too, but she didn’t pull away at first. Enjoying the show, she pressed it against you a little harder, coaxing your hips to gyrate, both to the rhythm of the song and in search of the vibrations. 

But once the phone rang a fourth time, you pushed her away with a dismissing laugh, telling her to go answer it. 

Your cheeks were flushed, and your heart was racing wildly within your chest. You covered your forehead with your palm, taking a deep breath as the people around you filled in the open space that her exit provided. 

The loss of contact with her allowed you to sober up the tiniest bit and get your head on straight. She was just like a drug.

Get a grip, you scolded yourself, shaking your head. This was ridiculous. Was going more than a few hours without fucking her really this impossible? You wanted it more than anything, but you didn’t want to give her the satisfaction of calling off your deal. It was made to prove a point, and you intended to keep it instated for that very reason.

You stole a glance at your watch. 

Only fifteen minutes left. That was doable, no?

Siyeon rolled her eyes as she slid up on the green button at the bottom of her screen. She had to fight the urge to just let it go unanswered.

Had it been anyone other than her boss, she likely would’ve. 

“Hello?”

“Ah, Siyeon,” he greeted from the other end, a smile evident in his gravelly voice. “I’m glad I could reach you.”

She pressed her back to an open portion of the far wall, away from the more rowdy parts of the crowd. 

“Of course, sir,” she sighed, withholding the attitude that she wished to lace into it. 

She looked up at you, watching you sway gently in time with the music. The light of the room painted you beautifully – every shimmer and shadow fighting for its chance to cast across your skin. She couldn't help but admire you from afar.

"...yes, sir. I turned that report in to your assistant two days ago." She answered distantly, clearly not entirely focused on their conversation. 

He launched into a response, but Siyeon suddenly tensed and stood up straighter – intrigued for a completely different reason.

A woman was making her way over to you.

Like a shark circling its prey. 

The blonde danced along to the beat with a drink in her hand, sipping on it as she closed the remaining distance between you. Siyeon could only watch as she leaned down, smiling prettily as she introduced herself. 

You laughed at something she said and nodded lightheartedly, amused. 

“Siyeon? Are you there?”

Her lips pressed tightly into a line. “Yes, sir. Continue.”

He did, but again she couldn’t pay much attention. She was too focused on the two of you standing far too close for her liking, and the nonchalant way that the woman invited you to join her for a dance. 

To Siyeon’s annoyance, you agreed and stepped forward. 

She drew you in and briefly settled a hand on your hip as the two of you got accustomed to the new song that the DJ started playing. You followed her lead, allowing her to sway with you. 

She was attractive, and the sight of you together stoked the fire of jealousy within Siyeon.

For what it was worth, though, you didn’t attach any deeper meaning to the exchange. You were simply dancing, after all, and you'd made it a point to flash your ring a few times to avoid any misunderstandings.

But Siyeon was in a different state entirely. 

Her blood boiled, and her grip on her phone tightened audibly. The poor thing groaned and squeaked from the pressure, pleading for her to ease up.

The woman locked eyes with her over your shoulder, practically taunting her as she dipped you down. The angle provided Siyeon an achingly beautiful view of your body, tempting her to admire the lines and curves that you created; but she was sobered up by the fact that it wasn’t exclusive to her. 

In that moment, anyone – including that woman – could see you looking so gorgeously spread out. 

That was her final straw.

She abruptly excused herself from the call, assuring her boss that she’d dial him up again at the first chance she got, before hanging up without another thought.

Bitterness radiated from her with every step that she marched closer to you, practically fuming. She moved people aside along the way, providing an opening for herself to return to you. 

You were uprighted by the woman at once and subsequently seized by Siyeon, who loomed angrily behind you. You were oblivious to the situation until you felt her presence as she entered your personal space. 

She emitted tension, and the sensation made you tremble; the territorial look she gave deterred the blonde, who raised her hands in a show of innocence before smiling knowingly and ambling to another part of the dance floor. 

Hesitantly, you went to turn around and face Siyeon. But her sudden grip on your hips prevented that, keeping you as you were.

Something firm pressed against your ass as she pulled you in, rutting with a restrained sort of gentleness that seemed difficult to maintain. It caught you off guard at first, but the swell of it, straining against the fabric of her pants, was something you'd recognize anywhere. 

It was your favorite toy. She had secretly put it on before you left the hotel earlier. Cheeky. 

How had you not noticed it before?

She ground against you again, aiming to give you a better feel for it, but made sure to remain somewhat inconspicuous to the people around you. Her hands caressed your sides, tentatively working their way downwards as she attempted to gauge your reaction. 

Her lips brushed the shell of your flushed ear, upturning the slightest bit in triumph when she felt your breath hitch. Your head turned to the side and your chin tilted ever-so-slightly, granting her full access.

“Do you feel that?" She asked lowly, clenching her jaw. “What you do to me?”

She couldn’t have cared less about the promise in that moment even if she had wanted to. With you looking as good as you did and flaunting yourself like that… behaving really was no longer an option. 

You nodded fervently, lacking the gift of speech. 

“You’re going to take care of that for me. Right now,” she emphasized, taking a hold of your wrist. 

Chest heaving, you turned around to face her. She shoved your hand between her legs, making you cup the toy as she pressed a harsh kiss to your lips. You melted into it, weak within her strong embrace. Obediently, you groped her again, making the other side of it rub up against her clit. You swallowed up the encouraging moan that she let out at the action.

She begrudgingly pulled away after a moment, but only enough to take your hand again and impatiently drag you towards the front door. Her movements weren’t the most graceful – seeing as that she bumped the two of you into other guests and nearly fumbled over her own feet along the way – but they were endearing. She wanted you so badly that appearing composed no longer mattered to her. 

And that feeling was beyond mutual.

- The Parking Lot -

Although they gave it their all to be seen, the city’s bright lights were muted by the thick fog that covered the windows of Siyeon’s car; they were mere blurs in the distance, becoming increasingly dulled with time. 

The steam served as an immediate tell of what was happening inside, just in case any particularly dimwitted onlookers failed to put two and two together after observing the rocking of the car. 

Part of you was afraid the entire thing would fall apart at any moment, based on how roughly Siyeon was taking you. 

Her body clung desperately to yours, only parting long enough for her to draw the toy out of you and drill it back in as she took you from behind. Her skin met yours repeatedly, filling the cabin of the car with filthy noises that made you wetter than you thought possible. 

“Fuck, baby,” she cursed, pressing your head further down into the seat as the snap of her hips grew messier and more erratic. Her fingers tightened in your hair, making your eyes water the slightest bit.

You smiled triumphantly, feeling the cool leather soothe your heated cheek. 

The decorative beads hanging from the rear view mirror clacked together, consistently colliding with the back of it.

Rhythmically, the press of your hips fell in time with her thrusts; you met in the middle, getting the most out of each and every move. Your muscles ached something wild, but you were beyond caring at that point; all that mattered was Siyeon, and ensuring that she got what she wanted. 

“Does it feel good?” You panted.

“So good, jagi,” she groaned, voice raspy, as she lolled her head to the side. 

Her hazy eyes landed on the hickies that she had left at the small of your back earlier, which she brought her free hand up to caress. Beneath her fingertips, your muscles flexed from the impact that she inflicted; they strained with the desperate, searching rutt of your hips as well, never stopping for a second. 

You were such a whore for her; she loved it.

"I wish you could see yourself like this," she mused through heavy breaths, palming your skin. "Taking me so well. God, you're so perfect." 

Her harsh thrusts mellowed into long, sensual ones as she focused on grinding against you. The ridges of the toy slid across your velvety walls as she humped, stimulating you further. She watched the length of it disappear inside of you repeatedly, only to reappear glistening more and more each time. 

You reached a shaky hand out to brace yourself, aware that she was getting close by the tremble of her legs.

All of the friction her clit was receiving was pushing her closer and closer to the edge. The other end of the toy moved inside of her as well, heightening the effect of even your most subtle motions. 

When your head fell forward and came to rest against your extended arm, she leaned down, seizing the opportunity to kiss your exposed neck. The way her body aligned with yours, completely bare and heated, made you moan. 

She left new marks everywhere she liked, taking her time.

A soft, pleased grunt resounded in her throat when you lifted your hips and grinded back into her, languidly working yourself along the toy. She stilled her movements and let you continue for a bit, reveling in the intimate feeling. 

"Head up, angel." She instructed, grazing her teeth across your pulsepoint. 

You obeyed and raised it, fighting exhaustion. 

Her lips found yours, and you immediately surrendered control of the kiss over to her. Despite knowing you'd grant it without hesitation, she still asked for permission by licking your bottom lip. 

You opened up, sighing as her tongue met yours. 

Instinctively, your walls fluttered at the feeling; she deepened the kiss, doing as she wanted.  

She snaked a hand down your body and pressed her fingertips to your clit, toying with it. She spread your slick around, proud of the mess of it that coated your thighs and pussy. It dripped down your legs, only turning her on more. 

Needing air, you broke the kiss. She clearly felt like showing a little mercy, as she allowed you the chance to catch your breath and kissed your shoulder in the meantime. 

When the toy hit your g-spot again following a particularly sensual roll of her hips, you whined pathetically at the feeling.

“Who do you belong to?”

“You, Siyeon,” you exhaled shakily.

“And who's the only one that gets to fuck you like this?” She pressed, voice commanding. 

You moaned, forgoing pride. “You.”

“That’s right, Y/N/N,” she grinned evilly, pushing herself back up. Her hands went to the small of your back again, applying a tantalizing pressure as you obediently arched for her, already knowing what she wanted. 

She wasn’t even close to being done with you yet. 

“Now, start counting. If you make it to twenty, I might just let you cum.”

The sound of her hand slapping your ass filled the car at once, intoxicating you in an entirely new way. 

“...one.”
