You were nestled in bed, engrossed in your favorite show, when your phone suddenly lit up. It was Joost. With a sigh, you paused the show and grabbed the phone.
"Hey, Joost. What's up?" you answered, curious about the late-night call.
"Hi Y/N, what are you up to?" Joost's voice came through, noticeably slurred and tipsy.
"I'm just relaxing in bed, watching some TV. What's going on with you?" you replied.
"I'm at this wild party at a friend's place," Joost said, his excitement palpable even through the phone. "You should totally come."
A grin spread across your face. "You know I can't resist a good party. And my FOMO is off the charts. Send me the address, and I'm there."
Joost chuckled, knowing he had you hooked. "I knew you'd say that. I'll text you the details right now."Â
He hung up before you could say anything more. With a sigh, you pressed play on your show again before you swung your legs out of bed to get ready for the party.
Opting for a casual look, you chose a black tube top and a flowy long white skirt that was slightly see-through in certain lighting. It was just a random house party, after all, but you still wanted to look effortlessly stylish. Your phone lit up again, this time with a text from Joost containing the address of the party.
Turning off the TV, you rummaged for drinks to bring along. You found a shot and downed it immediately, not wanting to show up completely sober. You grabbed a few more shots and a variety of canned drinks and put them in a bag, ready for the party.Â
You picked up your phone, took a selfie as you downed another shot, and sent it to Joost with the text, “Ready!”
With a buzz of excitement, you gathered your drinks and slipped on a pair of comfortable shoes. After a final glance in the mirror, you grabbed your keys and headed out the door.
The party wasn't far away, so you decided to walk to the nearest electric scooter. The cool night air felt refreshing as you approached the row of scooters, selecting one and scanning the QR code to unlock it.Â
With a slight thrill, you hopped on and zipped through the streets, the city lights blurring around you. The anticipation of the party mixed with the freedom of the ride made you feel alive.Â
As you approached the house, the sounds of laughter and music grew louder, guiding you to your destination. You parked the scooter nearby and walked up to the front door. Out of courtesy, you knocked before stepping inside. The house was crowded, but every face was familiar.Â
You searched the kitchen for a spot to set down your drinks, and as you closed the fridge and popped open a can, you caught sight of Joost guiding a girl toward another room. Although you and Joost had a casual friends-with-benefits arrangement and nothing exclusive, it still stung to see him with someone else, especially tonight. You couldn’t help but wonder why he’d invite you to the party only to focus his attention elsewhere.Â
You trailed behind, observing Joost lead her into the heart of a lively dancing crowd. Instead of joining them, you headed toward a nearby couch where a group was engaged in a drinking game. You plopped down and asked, “Mind if I join in?”
As you joined the drinking game, the laughter and lightheartedness of the group momentarily distracted you from Joost and the mystery girl. But your eyes kept drifting back to them, watching as they swayed together in the dimly lit living room. You tried to shake off the uneasy feeling, reminding yourself that you and Joost weren’t exclusive. Still, something about the situation didn't sit right with you.
A few rounds later, after downing more than a couple of shots, you decided you’d had enough of the silent torture. You weren't the type to just sit back and let things fester. Gathering your courage, you stood up, excused yourself from the group, and made your way through the crowd toward Joost.
You found him leaning against the wall, his arm draped lazily over the girl’s shoulders as they talked in hushed tones, their faces close. Your heart pounded in your chest as you approached, but you steadied yourself, determined to confront him.
“Joost,” you called out, loud enough to be heard over the music. His head turned slightly in your direction, his eyes meeting yours for a brief moment.Â
He smirked, but instead of acknowledging you, he turned back to the girl and said something that made her giggle. Irritation flared inside you. You stepped closer, feeling the heat rise to your cheeks.
“Joost,” you repeated, your tone firmer this time.
Finally, he glanced at you, his smirk still plastered on his face. “Hey, Y/N. Having fun?”
You crossed your arms, trying to keep your composure. “What’s going on? You invited me here, but it seems like you’re more interested in... other things.”
Joost raised an eyebrow, clearly amused by your frustration. He glanced at the girl beside him, then back at you. “Oh, come on, Y/N. We’re just having a little fun. No need to get all serious.”
You opened your mouth to respond, but before you could get a word out, Joost leaned in and kissed the girl right in front of you. It wasn’t just a peck either—it was a deliberate, slow kiss, meant to provoke.
Your heart sank as you watched them, feeling a mix of anger and hurt. Joost had always been playful, but this was different. He was doing it on purpose, knowing it would get under your skin. And it worked.
As they pulled apart, Joost looked at you again, his eyes gleaming with a teasing challenge. “Don’t be mad, Y/N. You know we aren't exclusive”
The girl glanced at you, her expression unreadable, but she didn’t move away from Joost. Instead, she stood there, almost as if she were waiting to see how you’d react.
You felt a burning need to say something, to do something, but a part of you hesitated. This wasn’t what you’d signed up for. The casual nature of your relationship with Joost had always been comfortable, but now it felt like he was pushing boundaries just to see how far he could go.
Taking a deep breath, you finally spoke, your voice steady despite the turmoil inside. “You know, Joost, this is just cruel.”
Joost’s smirk faded slightly, as if your words had hit a nerve. But before he could respond, you turned on your heel and walked away, pushing through the crowd. You didn’t know where you were going, but anywhere was better than standing there, feeling humiliated.
You found yourself outside on the porch, the cool night air hitting your flushed cheeks. You leaned against the railing, taking deep breaths to calm yourself.Â
As you stood there, lost in thought, you felt a presence beside you. You looked up to see one of the guys from the drinking game, his expression concerned.
“Hey,” he said softly. “You okay?”
You forced a smile, though it didn’t quite reach your eyes. “Yeah, I’m fine. Just needed some fresh air.”
He nodded, leaning on the railing beside you. “Joost can be a real jerk sometimes. Don’t let him get to you.”
His words brought a surprising sense of comfort, easing the tension that had been building all night.
"Want a cigarette?" he asked, pulling out a pack and offering it to you as he took one for himself.
You nodded, taking one from the box and placing it between your lips.
He lit his cigarette first, the flame briefly illuminating his face, then leaned in to light yours. The warmth of the lighter’s flame brushed against your skin, and your eyes met his for a moment longer than you expected. There was something in his gaze, something playful and inviting, that made the tension in your chest ease just a bit more.
As you both exhaled that first drag, the smoke curled up into the night air, mixing with the muted sounds of the party behind you. You took another drag, feeling the calm slowly settle in.
“So,” he began with a teasing grin, “do you always make such dramatic exits at parties, or is tonight a special occasion?”
You chuckled, rolling your eyes as you leaned back against the porch railing. “Only when the party’s worth it,” you replied, smirking. “Though I needed a good reason to escape that mess inside.”
He laughed, a warm sound that seemed to wrap around you. “Well, if you’re looking for an escape, I’m pretty good at keeping people distracted.” He leaned in just slightly, lowering his voice as if sharing a secret. “I’ve got a few tricks up my sleeve.”
You raised an eyebrow, intrigued. “Oh yeah? And what kind of tricks are we talking about?”
He took a slow drag, his eyes never leaving yours. “I could start with some bad jokes, move on to charming conversation, and maybe—just maybe—end with something more interesting.” His gaze dipped briefly to your lips before returning to your eyes, the suggestion clear.
You felt your pulse quicken, the playful tension between you growing. “Bad jokes, huh?” you teased, trying to ignore the way his attention was making your heart race. “You must be a real pro.”
“Only when I’m inspired,” he shot back, his grin widening.
You laughed softly, the sound mingling with the crackling of your cigarettes. There was something undeniably magnetic about him, something that made it easy to forget the mess with Joost inside.
Before you could think too much about it, you took a step closer, closing the small gap between you. “Well,” you said, your voice a little softer, “maybe you can show me one of those tricks right now.”
He didn’t need any more encouragement. His eyes flickered with interest as he leaned in, the world around you fading until it was just the two of you on that porch. You could feel his breath against your lips, the anticipation crackling in the air. And then, with a slow, deliberate movement, he closed the distance and kissed you.
The kiss was warm and gentle at first, testing the waters, but it quickly deepened as you responded, your hand moving to the back of his neck. His free hand found your waist, pulling you closer, and for a moment, everything else vanished—the noise from the party, the tension from earlier, even the lingering thoughts of Joost. All that mattered was the feel of his lips on yours and the way he was holding you as if he didn’t want to let go.
But the moment was shattered when the door to the house swung open. You broke the kiss and pulled away, feeling the heat of the moment, but as soon as Joost’s voice cut through the air, your heart sank. You looked over the guy’s shoulder to see Joost standing in the doorway, his expression a mix of surprise and something else—something that made your stomach twist with uncertainty.
“Y/N,” Joost said, his voice cool and controlled, a smirk playing at the corner of his lips. He stepped onto the porch, his eyes drifting lazily between you and the guy beside you, who still had his hand on your waist. “Didn’t think you’d move on so quickly. Guess I underestimated you.”
The comment was sharp, laced with a mocking edge that sent a wave of irritation through you. You stepped back, putting some distance between yourself and the guy, who was now looking at Joost with a raised eyebrow, clearly sizing him up. But it wasn’t the guy beside you that had your attention—it was Joost and the way he was looking at you, like he was toying with you.
“Joost,” you started, your voice steady despite the emotions swirling inside you. “What do you want?”
He chuckled, a low, almost condescending sound, as he took a step closer, completely ignoring the other guy. “I just came out to get some air, but it looks like I walked in on something... interesting.” His eyes flicked to your lips, then back up to your eyes. “So, is this what you do now? Kiss random guys at parties?”
You felt your cheeks flush with a mix of anger and embarrassment. “And what about you?” you shot back. “You were the one all over that girl inside, or did you forget?”
Joost’s smirk widened, clearly enjoying the back-and-forth. “Oh, I didn’t forget. But I wasn’t expecting you to get so jealous. I mean, it’s not like we’re exclusive or anything, right?”
The words stung, and Joost knew it. He was pushing your buttons, testing how far he could go. The guy beside you, sensing the tension, took a step back, clearly realizing this was between you and Joost.
You took a deep breath, trying to keep your composure. “Why did you even invite me here, Joost? To play games? To mess with my head?”
He shrugged, his gaze never leaving yours. “Maybe I just wanted to see what you’d do. I like keeping things interesting.”
You narrowed your eyes at him, refusing to back down. “You’re unbelievable, you know that?”
“Maybe,” he admitted, his smirk softening into something more genuine as he closed the distance between you. “But you like it, don’t you? You like that I keep you guessing.”
He was so close now that you could feel the heat radiating off him, his presence overwhelming. Part of you wanted to push him away, to walk back into the house and leave him standing there. But another part of you—the part that had always been drawn to his teasing, his unpredictability—couldn’t bring yourself to move.
“You know,” Joost continued, his voice low as he reached out and brushed a strand of hair behind your ear, “you’re not the only one who gets jealous. Seeing you with him...” He nodded slightly toward the guy who was now leaning against the porch railing, watching the interaction unfold. “It made me realize something.”
You raised an eyebrow, skeptical. “And what’s that?”
“That I don’t like sharing,” he said, his voice dropping to a whisper as his fingers trailed down your cheek. “Especially not when it comes to you.”
His words sent a shiver down your spine, the intensity in his eyes making your breath hitch. He leaned in closer, his lips just a hair’s breadth from yours, his teasing smirk still in place.
“You like being teased, don’t you?” he murmured, his breath warm against your skin. “Admit it, Y/N. You love it when I push your buttons.”
You opened your mouth to protest, but before you could say anything, Joost closed the gap, capturing your lips in a kiss that was both demanding and intoxicating. This kiss was different from the one you’d shared with the other guy—it was filled with a fiery possessiveness, as if Joost was staking his claim.
Despite yourself, you found yourself kissing him back, your hands gripping the front of his shirt as you pulled him closer. It was infuriating how easily he could get under your skin, how much you craved this dangerous dance between you two.
When he finally pulled back, his forehead resting against yours, you were both breathing heavily. “See?” he whispered, his voice a mix of arrogance and affection. “You can’t resist me.”
You bit your lip, trying to regain some control. “You’re such a jerk,” you muttered, but your words lacked conviction.
Joost chuckled softly, pressing a quick, teasing kiss to your lips before pulling away slightly, his eyes still locked on yours. “Maybe, I am” he agreed, “but you like it”
Just as you were about to respond, the other guy cleared his throat, reminding you both that he was still there. Joost glanced over, his smirk returning as he gave the guy a mocking nod. “Thanks for keeping her company. I’ll take it from here.”
The guy rolled his eyes but didn’t argue, instead giving you a small, understanding smile before turning to head back inside, leaving you and Joost alone on the porch.
As the door closed behind the other guy, the night air seemed to grow still around you and Joost. The intensity of the moment hung heavy between you, and you could feel Joost’s gaze on you, sharp and possessive. He didn’t let go of your hand, his thumb tracing slow, deliberate circles on your skin.
He leaned down, his lips trailing along your neck, sending a shiver through your body. A soft whimper escaped your lips; you were powerless against him, and he knew it. He had you wrapped around his finger, completely at his mercy. You wanted something real, a relationship that meant more, but deep down, you knew he saw you as nothing more than his toy, something he could enjoy on his terms, whenever he pleased.
As his lips continued to explore your neck, each kiss igniting sparks under your skin, you felt the bittersweet ache in your chest intensify. You were caught between the intoxicating pull of his touch and the painful truth that settled in your mind: you were just a fleeting pleasure for him, a secret indulgence.
Joost’s hands roamed over your body with a practiced ease, every movement claiming more of you, making it harder to remember why you wanted something more. His teeth grazed your skin, drawing another helpless whimper from you, and a low, satisfied growl rumbled in his chest.
“You like this, don’t you?” he murmured against your skin, his voice thick with arrogance. “You like being my toy”
You couldn’t deny it. The way he made you feel, the way he dominated every part of you, was intoxicating. But it wasn’t enough. You wanted more—more than just stolen moments and empty promises. You wanted to be more than just his plaything.
But as his hands gripped your hips, pulling you even closer, you felt your resolve waver. It was so easy to give in, to let yourself be swept away by the heat of the moment, to forget everything else.
Yet, deep down, the truth gnawed at you. This was all he was willing to offer, and as much as it hurt, you knew you were powerless to change it. The thought stung, but the way he held you, the way he touched you, made it so hard to resist. You were trapped in a dangerous game, one that left you longing for more even as you knew you’d never have it.
Joost pulled back slightly, his eyes meeting yours, a smirk playing on his lips. “You’re mine,” he repeated, his voice a possessive growl, as if daring you to deny it.
And despite everything, despite the yearning for something real, you couldn’t bring yourself to pull away. Instead, you nodded, your voice barely a whisper as you replied, “Yes, I’m yours.”Â
But even as the words left your lips, you knew they carried a weight that neither of you fully acknowledged—a truth buried beneath the surface of a relationship that was anything but simple.
