TW SMUT

Yeonjun is working on his bike in the paddock, trying to get ready for his next race. He's dressed in his racing leathers, which hug his body just the right way. He's bent over the bike, working on some part or another when he feels eyes on him.

He looks up and notices Sex On Legs approaching.

Choi Soobin is dressed a bit more casually, though as always he looks very stylish in the way that only a billionaire can. He's wearing a tailored blazer with a white shirt under it, and blue jeans with matching sneakers.

"Hey," Soobin calls out as he approaches the pit area.

Yeonjun is a little surprised by the casual attire, but smiles at Soobin. "Hey." He finishes up the work on his motorcycle and then gives his full attention to Soobin. "What's up?" he asks, noticing the way Soobin is checking him out.

"Nothing," Soobin says as he looks up and down Yeonjun's body. There's a hunger in his eyes, and he reaches out to touch the biker boy's hip. "I just like to come watch you work on your bike sometimes," he admits with a coy smile.

Yeonjun doesn't flinch at the touch, a bit used to Soobin's advances by now. He smirks at the billionaire, taking a bit of pride in the attention.

"Did you come just to watch me then?" He asks boldly, challenging him.

Soobin smirks back at the challenge and moves his hand around to squeeze Yeonjun's butt. "Actually," he says, leaning in closer. "I came to talk to you about something."

Yeonjun feels the squeeze and raises an eyebrow in surprise. The boldness isn't unexpected, but it's still something he's getting used to.

"Oh yeah? What's this something about?" He asks curiously, his eyes going to Soobin's hand on his butt with an amused smile.

Soobin gives him another squeeze and chuckles at the way Yeonjun is looking at him. "Well," he says, pulling his hand away and leaning against the bike next to the biker boy. "I was thinking about you racing for me this season."

Yeonjun raises his eyebrows at this. "You want me to race for you?" he asks, his eyes lighting up as he realizes the possibilities this opens up.

Soobin nods, leaning down a bit so that his mouth is closer to Yeonjun's ear. "It would mean giving up your current sponsorship, but I'd pay you a lot more than they do. And you'd be driving one of my own bikes...." He places his hand on Yeonjun's hip again, his pinky touching the biker boy's waistline. "What do you think?" He practically purrs into the ear.

The proposal and the way Soobin leans closer has Yeonjun's heart racing. He'd definitely be up for driving Soobin's bikes and getting paid more, but there would be something to consider.

"And what about our.... arrangement?" Yeonjun asks referring to the friends with benefits thing they've got going on (only they're not friends), his eyes on Soobin's hand and his tongue flicking out to lick his lips.

Soobin's eyes follow Yeonjun's tongue. He smiles at the other boy's words, his hand moving to the small of Yeonjun's back. "Well, I still expect it to continue the same... I'm simply giving you some more perks through this new proposition. That is if you agree to dedicate yourself entirely to me," He says, a hint of a challenge in his words. "Not giving your attention to anyone else."

He tilts his head, his fingers tracing small circles on Yeonjun's back. "Do you think you could do that for me?" he asks, his voice smooth and seductive.

Yeonjun leans into Soobin's touch, his mind racing with thoughts of what it would mean to dedicate himself entirely to Soobin. He imagines driving his imported sports bikes and getting paid much more while also enjoying all the other "perks" that come along with their.... already existing arrangement.

The thought does interest him, but he decides to tease the billionaire a bit.

"I don't know," Yeonjun says, his voice playful, his eyes locked on Soobin's. "You might have to bribe me a little bit."

Soobin chuckles at this, not surprised that Yeonjun is being a little cheeky. He leans in even closer, his hand now firmly resting on Yeonjun's butt. "Oh yeah?" he asks, his voice low and sensual as his other hand rests on the biker boy's waist. "What do you want, Yeonjun?" His eyes are dark and heavy with lust, his fingers tracing circles on the fabric. "What would it take to get your full attention?"

The physical contact and the way Soobin is talking to him are sending shivers down Yeonjun's spine. He's already practically sold, but he wants to keep up the challenge just a little longer. He smirks at Soobin, leaning in so their faces are mere inches apart.

"Well, what do you have to offer?" he asks, the words coming out slightly breathless as he feels Soobin's fingers tracing circles. "Not just anything is going to win me over, you know."

Soobin's fingers dig in at that, pulling Yeonjun closer. "Anything the biker boy wants," he practically growls out, his voice full of want.

Soobin nuzzles into Yeonjun's neck, leaving soft kisses under his ear. "How about I promise to give you a ride you'll never forget?" he asks, his eyes dark and hooded as his hand gives another squeeze to the biker boy's butt. "What do you say, Yeonjun? Is that something worth your full attention?"

The words and the attention from Soobin has Yeonjun's mind racing once again. He can practically feel the billionaire's desire to have him, and his body responds to the touch. But he's not quite ready to give in completely, not yet.

"I'm still not sure," Yeonjun purrs. "You'll need to do a lot more to convince me, you know." His hand moves to Soobin's chest, touching him through the fabric of his blazer. "Show me what you've got."

Soobin's hand moves to cup Yeonjun's face, his thumb brushing against the boy's lower lip. "I think I can do that," he says, his voice low as he presses himself against Yeonjun. "Let me take you somewhere private." His lips move to Yeonjun's ear, nipping at the lobe. "I'll show you exactly what I've got," he whispers, his fingers grazing down to the biker boy's hips.

Yeonjun shivers at the touch and the words. He can feel heat building in him as his lips part a bit under Soobin's thumb. His body responding to the billionaire's actions, despite his attempt to remain cool and composed.

He smiles at Soobin, his fingers tracing the collar of his blazer. "Lead the way," he says, biting his lip in anticipation of what's to come.

Soobin smirks at the response, enjoying the effect he has on the boy. He pulls away just a small amount, his hand taking Yeonjun's and leading him away from the paddock.

He leads him to a nearby luxury car, parked just off to the side. It's Soobin's personal car that he had gotten imported from Germany, and a clear indication of his wealth.

Soobin opens the back door for Yeonjun, gesturing for him to get in. "After you," he says, his voice laced with promise.

Yeonjun climbs into the back seat, feeling the luxurious leather against his body as he settles in. The heat that had been building in him has only intensified, and he looks up at Soobin with dark eyes as he waits for the other boy to join him.

"So, is this where you plan to show me what you've got?" Yeonjun asks, his voice now a bit breathless with anticipation. He crosses his legs, his eyes drinking in Soobin's form.

Soobin smirks as he slides in next to Yeonjun, shutting the door behind him. The car is comfortable and highly spacious, offering more than enough room for all of their... activities.

He puts an arm around the biker boy's waist, pulling him closer as he leans down to kiss at his neck.

"This isn't the only place," Soobin murmurs, his lips grazing the sensitive skin. "But it's a good start." His hand moves under Yeonjun's shirt, fingers teasing against exposed skin. "Are you ready to see what I've got?"

The touch under his shirt sends a jolt of pleasure through Yeonjun, his body responding to the billionaire's hand almost as if on autopilot. He arches his back slightly, wanting to feel more of Soobin's touch.

"Of course," Yeonjun purrs, his hand moving to Soobin's hair. His fingers thread through his silky locks, giving a small tug to get the billionaire's attention. "You better make it worth my while, Choi Soobin."

Soobin smirks in response, lifting his head from Yeonjun's neck to look into his eyes. He takes in the expression on the biker boy's face, the way his hands are tangled in his hair... it only adds to the feeling of hunger inside of him.

He cups the back of Yeonjun's head and brings him in for a kiss, his lips claiming his in an intense embrace. The kiss is hungry, demanding, and full of desire.

"Oh, I've got a lot in store for you, Yeonjun," he practically promises when he breaks away.

The kiss only increases the heat within Yeonjun, and he eagerly returns it. His hands slide down to Soobin's shoulders, gripping tightly as he feels the billionaire's tongue against his own.

A small sound escapes him, muffled by the kiss. His body is on fire, his mind clouded by the intensity of the kiss. His lips part easily for Soobin, his tongue meeting his in a battle for dominance.

Soobin's hand moves in tandem with his tongue, his fingers tracing patterns on Yeonjun's exposed skin. He can feel the heat and desire coming off the biker boy, and he wants nothing more than to consume him whole.

He pulls him closer, his other hand moving down to grasp Yeonjun's thigh, squeezing it firmly. The sound the other boy makes only spurs him on, and he deepens the kiss even further, his tongue exploring every inch of Yeonjun's mouth.

The hand on his thigh only serves to bring out another sound from Yeonjun. He shifts slightly in the seat, the bulge in his pants growing more and more as Soobin kisses him deeper. His hands move up to push aside the other boy's blazer, tugging on the fabric of his shirt.

His fingers graze over the toned muscles on Soobin's torso, feeling the heat coming off of him as well. He pulls back slightly, breaking the kiss as he gasps out, "Soobin..."

Soobin pulls back when he hears his name, his eyes meeting Yeonjun's. He can tell what the biker boy wants, and he's more than ready to give it to him.

His hand stays on Yeonjun's thigh, his fingers tracing small circles as he licks his lips.

"Yeonjun," He breathes, his voice low and husky. "What do you want?" He leans in, his lips ghosting just above the biker boy's ear. "Tell me what you need."

(Yeonjun may be a motorcycle professional on the race track, but in the back seat of Soobin's luxury car.... It's obvious who will be doing the riding.)

Yeonjun's hands grip at Soobin's shirt, tugging slightly. He shifts in his seat again, his breath coming out in little gasps as the other boy's lips graze his ear.

"I need you," he whispers, his voice husky with desire. "I need you to show me what you've got." His head tilts to the side, giving Soobin better access to his neck.

Soobin needs no more prompting. He immediately latches onto Yeonjun's neck, attacking the sensitive skin with his lips and teeth. His hand slides higher up the biker boy's thigh, reaching the bulge in his pants.

Yeonjun moans at the touch, arching into Soobin's lips. His hips press into the billionaire's hand, already seeking more friction. The feeling of the billionaire's lips on his neck only adds to his arousal, his mind a blur of sensations.

Soobin continues to kiss and nibble at Yeonjun's neck, loving the way he arches into him. He can feel the anticipation building inside of him, a heady desire that's only growing. He wants to see the biker boy come apart beneath him, to lose control of his every thought and action.

His fingers tease the outline of Yeonjun's bulge through his pants, knowing exactly what that hand gesture will do to him.

The sensation sends a jolt of pleasure straight to Yeonjun's core. He gasps, his hips bucking into Soobin's touch.

"Soobin," he moans, his fingers gripping the other boy's shirt tightly. "More." He arches his neck, giving Soobin more space to work on, his body craving everything the billionaire has to offer.

The word "more" is like a switch flipping in Soobin's mind. He immediately pushes his lips back to Yeonjun's, capturing them in a passionate kiss.

His tongue slides past Yeonjun's lips, mapping out every inch of his mouth. His hand keeps working the biker boy, giving a firm squeeze before his fingers find the zipper.

"Wanna try something new with you...." Yeonjun cups the side of his jaw. "Spit in my mouth, Soobin."

Soobin breaks the kiss, a thin string of saliva connecting their lips as he gazes darkly at him. His pupils are blown wide, a dangerous glint in his eyes as he looks at Yeonjun.

"You want that?" He asks breathlessly, the words coming out in more of a growl than anything else.

Yeonjun's eyes are equally dark with desire. "Do it," he says, his voice low and rough. He licks his lips, his tongue darting out to wet them as he waits for Soobin to take action.

Soobin doesn't even hesitate. He leans in, his tongue delving past Yeonjun's lips, seeking out the wet warmth waiting for him.

Yeonjun's lips part easily, welcoming Soobin's tongue with his own. He lets out a low moan, the noise muffled by the billionaire's mouth. His hands tangle in Soobin's hair, fingers gripping almost desperately for something to hold onto as his head swims with pleasure.

Soobin explores Yeonjun's mouth thoroughly, wanting to taste every inch of it. His hand still works on the biker boy, moving to undo the zipper and slip inside his underwear.

"Do it please." Yeonjun pants.

Soobin breaks away briefly, his chest heaving as he tries to catch his breath. "Are you ready?" He asks, his voice raspy. He leans back in, his thumb pressing against Yeonjun's lower lip. "Open up for me, baby."

Yeonjun does as he's told, opening his mouth wide and waiting for Soobin to give him what he desires. He looks up at the billionaire through his lashes, his eyes dark and hungry for more.

Soobin leans in closer, his hot breath against Yeonjun's lips, teasing him. He's so close that Yeonjun can feel the billionaire's breath, smell the spicy scent of his expensive cologne.

Then, finally, he leans back enough for a bead of saliva to slip from his mouth, landing on Yeonjun's waiting tongue.

Yeonjun closes his eyes as he feels the warm, wetness of Soobin's spit. His mind goes blank, the only thing that matters is the sensation of it trickling down his tongue. His fingers grip the back of Soobin's head, pulling him back once more. "More," he breathes, need and desire in his voice.

Soobin gives a low chuckle at the reaction, loving the way Yeonjun responds. He leans in again, his lips just brushing against his.

"More?" He teases, his tongue darting out to touch his lips. "What do you want, Yeonjun?"

The tip of his tongue traces the outline of his lips, tantalizing and torturous, before slipping past to explore his mouth. He slides his free hand up the inside of Yeonjun's thigh, kneading the muscle as he goes higher.

Yeonjun moans against Soobin's mouth, the sound muffled by the intense kiss. His hands move from the billionaire's hair to his shoulders, gripping the fabric of his jacket to pull him closer. His hips push up involuntarily as Soobin's hand grazes his inner thigh, seeking out the touch.

He breaks the kiss, his eyes looking into the billionaire's with a need for more. "Give me everything," he pleads, his voice thick with arousal as he bites his lip.

Soobin's eyes darken at Yeonjun's words, the sound of his desire and the sight of him biting his lip enough to make him snap. He gives the Biker Boy a fierce kiss that is mostly teeth and tongue before pulling away, a fire burning in his gaze.

"Everything?" he echoes, voice rough and low. His hand continues to tease Yeonjun, making him shiver with anticipation. His lips ghost against his ear as he speaks. "Are you sure you can handle it?"

Yeonjun shudders at the billionaire's tone, his body responding instinctively. "Yes," he gasps, his hips arching up in desperation. "I can handle it, I want it all." His breath comes in short, shallow bursts as he waits for Soobin to make the next move.

Soobin growls at the admission, his hands moving to remove the biker boys shirt with one swift yank. He pushes him back against the seat and climbs on to straddle him, his lips finding Yeonjun's neck once more.

He grinds down against the boy as he bites and sucks at the sensitive skin there, wanting to mark him as his own. "Good," he murmurs, his hands moving down to undo the biker boy's belt. "Because I'm going to give you everything you crave and more."

"Want you to do that thing again too..." Yeonjun whispers hotly.

Soobin pulls away from Yeonjun's neck, looking down at him with a predatory gaze. He licks his lips, a slow and deliberate movement, before leaning in close to the biker boy's face.

His lips touch Yeonjun's, the kiss soft and teasing. "Open up for me, Yeonjun. Don't you want what you came for?" he whispers, his thumb tracing over the biker's bottom lip.

Yeonjun eagerly opens up, his mouth hot and needy as he waits for the billionaire to spit. He's lost in the sensation of Soobin's thumb on his lip, his body trembling with anticipation.

"Please," he breathes, "give it to me."

Soobin's eyes darken at the words. He leans back a little, his lips lingering just above Yeonjun's mouth and his thumb moving back and forth on his lower lip. He waits a few more moments, letting the anticipation build, before finally spitting a huge bead of saliva into the biker boy's mouth.

Yeonjun closes his lips around the liquid, letting it fill his mouth before swallowing it down. He lets out a soft moan as he does so, savoring the taste of Soobin on his tongue.

"Mmm..." Yeonjun hums, his eyes half-closed. "Taste so good..." His tongue darts out to wet his lips again, his hands tugging at Soobin's shirt. "More," he whispers, his voice needy.

Soobin groans at the sight, his eyes fixed on Yeonjun's mouth. He leans back in, his lips crashing against his in a bruising kiss. His tongue invades Yeonjun's mouth, tasting the remnants of his own spit mixed with the boy's unique flavor.

His hand grips Yeonjun's hair, tilting his head back so he can deepen the kiss. He wants to swallow every sound that comes from Yeonjun, taste every inch of him with every part of his being.

Yeonjun's hands cling tightly onto Soobin, his body arching into his kiss. The sensations are overwhelming, his mind buzzing with pleasure at Soobin's intense kiss. He meets his tongue with his own, a low moan escaping him as he surrenders completely to the billionaire.

His hips push up against Soobin's, seeking out more friction between their bodies. He can feel the heat spreading through him, threatening to consume him whole.

Soobin pulls back from the kiss, his eyes fixed on Yeonjun's face, waiting for him to open his mouth wide once again. His breath comes out in soft pants, the arousal heavy inside of him.

Yeonjun quickly obliges, opening his mouth wide for Soobin once more. His tongue darts out to lick his lips, waiting eagerly for what comes next. He can feel the billionaire's eyes on him, the weight of his desire heavy in the small space of the car.

Soobin leans in once more, his mouth hovering inches above Yeonjun's. He waits just long enough for the boy to let out a shuddering breath before spitting another huge glob of saliva into his waiting mouth.

Yeonjun eagerly accepts the gift, his throat working as he swallows. He gives Soobin a wicked grin as he licks his lips, the taste of the billionaire's spit still lingering on his tongue.

"You spoil me," Yeonjun murmurs, his hands sliding down to Soobin's hips. He pulls him closer, the bulge in his pants now pressed against Soobin's inner thigh. "Can I make a request?"

The billionaire chuckles at the comment. "Maybe you earned a little spoiling," he teases, his lips finding Yeonjun's neck once more. He places a soft kiss on the skin beneath his ear, his tongue teasing it.

He hums against Yeonjun's ear. "Alright, biker boy. What's your request?"

Yeonjun bites back a moan at the sensation, his hips pushing up against Soobin again. His mind is buzzing, his body craving more and more.

"More," he pants, his words coming out in a breathy whisper. "I want more. Give me more, Soobin." He tilts his head back, giving the billionaire better access to his neck. "Your mouth, your tongue, your spit. I want all of it." His hands grip Soobin's hips, pressing him even closer.

Soobin shivers at the request, his eyes darkening with desire. "As you wish," he purrs before claiming the biker boy's lips once more. His tongue delves deep into his mouth, exploring every inch with a fierce hunger.

His hands slide down to Yeonjun's pants, his fingers finally undoing the belt and zipper in an instant. He pulls away from the kiss just long enough to say, "Lift your hips up."

Yeonjun complies with Soobin's command, lifting his hips off of the seat. His mouth leaves a soft whine from the loss of contact with the billionaire as he does so, his eyes locked onto the other boy's hands. His breath comes out in short, excited bursts as he watches Soobin undress him with practiced efficiency.

His hands slide down to Soobin's belt once he's done, trying to do the same for him. "Get these off," he whispers.

Soobin's mouth twitches in amusement at Yeonjun's eagerness, his hands easily unbuckling his belt and yanking his pants down. He kicks them away from his legs, now fully focused on Yeonjun in front of him.

His fingers trail up and down the biker's inner thigh, his touch leaving goosebumps in its wake. "Eager, aren't you?" he teases. "What do you want me to do, baby? You need to use your words."

Yeonjun moans at the sensation, his hips shifting beneath Soobin's touch. He can feel the billionaire's fingers dancing across his skin, causing a heat to build inside of him.

His hands slide down to Soobin's hips, gripping the billionaire's waistband. "I want you," he breathes, his voice rough with need. "Inside. Now."

Soobin smirks at the demand, his hands working to remove the rest of Yeonjun's clothes. He gives a low growl, his voice rough. "I need you to be specific, Yeonjun." His fingers tease at the biker boy's entrance, just barely brushing against it.

He looks into Yeonjun's eyes, his own dark with lust as he waits for the boy to say what he wants. "Use your words."

Yeonjun shudders at the touch, his hips instinctively pushing against Soobin's fingers. "You know what I want, Soobin," he breathes out, his fingers tugging on the billionaire's waistband. "Stop teasing me. I want you. You know how to give it to me."

He leans back in the seat, his hand pulling the billionaire even closer. The heat between them is almost unbearable now, and he can feel the anticipation coiling in his stomach.

"Use your mouth. Show me what you can do, Choi."

Soobin growls again at the command, his hands moving to push Yeonjun's legs up and to either side. He licks his lips in anticipation, his eyes locked on Yeonjun's.

He leans in closer, his mouth hovering inches away from the biker boy's entrance. He looks up from beneath his lashes, a wicked gleam in his eyes as he smirks. "If this is what you want, biker boy, just say the word."

Yeonjun arches his back, his breath coming out in short, quick pants. He wants this so badly, needs it like he needs air. But he has to make Soobin say it first, needs to hear the words leave the billionaire's mouth.

His hands grip tighter onto Soobin's waistband. "Soobin," he whispers, his voice barely audible over the sound of his own heart beating in his ears. "You say it."

Soobin licks his lips in anticipation, a small smile playing on the corners of his mouth. "You want me to beg, Yeonjun?" he asks, his voice teasing as he looks up at the biker boy. "You want me to say please?"

"Not how it works, baby." He leans forward, his mouth hovering just above Yeonjun's entrance. "It's you who needs to beg for it," he murmurs, his tongue darting out to taste him. "Beg me for what you want."

Yeonjun groans as Soobin's tongue touches him, his body thrumming with need. He opens his mouth, his words coming out in a pleading whisper. "Please, Soobin," he breathes, his hips bucking upwards. "Please, you know what I need. Give it to me."

Yeonjun squirms beneath the billionaire's hands, his whole body feeling like it's on fire with desire. "I need you."

Soobin smiles at the desperation in Yeonjun's voice, the words he knew he'd hear. "Please what, Yeonjun?" he teases, his fingers stroking along the biker boy's inner thigh. "Please what? What do you want?" His tongue brushes against Yeonjun again, slowly teasing at his entrance.

He knows what Yeonjun wants, but he needs to hear it. He wants to know how much the biker boy needs him. "Say it, sweetheart. Say it and I'll give you everything."

Yeonjun's hips move to chase the feeling of Soobin's tongue, a low moan escaping him. His hands grasp around the billionaire's waist tightly, his words a desperate plea. "Please, Soobin," he pants, his voice strained with need. "I need you inside."

The words fall from his lips like a prayer, his eyes fixed on Soobin's face. "Please."

Soobin gives a low chuckle in response, the sound sending shivers down Yeonjun's spine. His fingers continue to tease at his entrance, his lips placing soft kisses alongside it.

"Beg all you want, biker boy," Soobin murmurs against the sensitive skin. "But I won't do anything until you say the words." He gives his entrance a small lick, teasingly. "Say it, Yeonjun. You know what I want."

Yeonjun's body is on edge, the sensation only driving him closer to the edge. He's so close he can feel it, the pleasure coursing through him. But he needs Soobin, needs the billionaire's touch like he needs air.

His hands grip even tighter, his words a desperate plea. "Please, Soobin," he groans, his voice shaky with need. "Inside, now."

Soobin's eyes burn with desire as he sees Yeonjun's desperation. The biker boy's words, his actions, all of it is enough to make him lose control. He gives one last quick tease with his tongue before rising up to claim Yeonjun's lips in a deep, demanding kiss.

As he does so, he slips his tongue into the biker boy's mouth, his hands moving to undo his pants. He wants to give him everything he craves, and to show him exactly who he belongs to.

Yeonjun responds eagerly to the kiss, eager to taste Soobin's tongue again. His hands are everywhere at once, touching and gripping and clawing at anything they can reach. He's already hard and aching, but right now all of his focus is on the billionaire above him.

He pulls back just enough to whisper against Soobin's lips, his breath hot and heavy. "I need you, Soobin. Don't make me wait any longer."

Soobin can feel the desperation coming off of Yeonjun in waves, the boy practically begging him for it. He can't resist the urge to tease him a bit more, even as he reaches into his pocket for a packet of lube.

"Please what, Yeonjun?" he asks again, his breath hot against Yeonjun's neck. He presses his hips forward, grinding into the biker boy and causing him to gasp out. "Tell me exactly what you need. And maybe I'll give it to you."

Yeonjun's head is swimming with arousal, the billionaire's voice in his ear only heightening his senses. His back arches as Soobin grinds down against him, and he can't help the soft moan that escapes him.

He grips onto Soobin tightly, his head tilting back to show off the line of his throat. He gives a little chuckle, his own voice low and rough. "You heard me, Soobin," He purrs. "Please."

Soobin leans in to kiss at the exposed neck once more, leaving a hot trail of kisses along the line of his throat. His hand comes back from his pocket with the packet of lube, a smirk in his voice as he rips it open.

He reaches between them, his fingers teasing around Yeonjun's entrance. And in that same moment, he whispers against the biker boy's ear, "You're mine, Yeonjun."

And before Yeonjun can reply, Soobin plunges a finger inside of him.

Yeonjun gasps and arches against Soobin's finger, his whole body responding to the sudden, but much-needed sensation. His hands cling to Soobin tightly, gripping anything they can find.

The phrase "You're mine" lingers in his mind, and he can't help but feel a thrill at the possessiveness. He wants to be Soobin's, in every way the billionaire wants him. "Please, don't stop," he breathes out, his body already moving to meet Soobin's touch.

Soobin doesn't answer, his eyes focused entirely on the biker boy before him. He watches every reaction, his body language, the way he responds to his touch. When he feels Yeonjun relax around his finger, he adds a second one, his lips back on his face.

He kisses him deeply, his tongue working its way back into Yeonjun's mouth. His fingers start to move inside of him, stretching him out with expert ease. "You want more?" Soobin asks between kisses. "Beg me for it."

Yeonjun's world is filled with pleasure, his breath ragged as Soobin continues to touch him, to taste him. His mind is a storm of sensations, and he's almost overwhelmed with the need for more.

His words form a shaky plea. "Please, Soobin, don't stop," he breathes out against the billionaire's lips. He's beyond shame now, beyond caring about how desperate he must sound. He needs this, needs Soobin, and will do anything he wants to get it. "I want you. I need you."

Soobin gives a throaty growl at Yeonjun's words, his fingers moving more roughly inside him. He plunges in and out, each time making sure to stroke against his most sensitive spot. He drinks in the biker boy's moans like a man starved, eager to fill him up.

"Look at me," he commands in a low voice, his eyes locked on Yeonjun's face. "Tell me one more time."

Yeonjun's eyes lock on Soobin's, the look in them hungry and pleading. He's a mess beneath him now, his whole body trembling with need. "I need you," he repeats, his voice desperate. "I need you, Soobin. Please. Don't make me beg again."

He arches his body to meet each stroke of Soobin's fingers, his whole world narrowing down to the billionaire. To his touch, to his words, and the way they make him feel.

Soobin can feel the fire burning within him, his need for Yeonjun reaching its crescendo. He leans in, his voice filled with an animalistic hunger. "You're mine," he repeats, his words filled with a dark kind of possession. His fingers move faster inside him, hitting that spot over and over, knowing exactly what it's doing to the biker boy.

"Mine, Yeonjun," he murmurs against his ear. "You'll be screaming it loud enough for the whole paddock to hear by the time I'm done with you."

Yeonjun's back arches off the seat, a loud moan escaping him as Soobin's fingers hit his sweet spot. "Yes, yes –" he gasps out, his body shaking with pleasure. His hands grip Soobin tighter, nails scraping against his skin as he tries to ground himself.

The words "you're mine" send him even closer to the edge, every nerve in his body alight with desire. He wants nothing more than to give himself to Soobin, surrendering completely to the billionaire's touch.

Soobin withdraws his fingers, his chest heaving from his own arousal. His eyes are dark with hunger, his own need for the biker boy taking over all logic and reason. He presses his body against Yeonjun's, his words a command – "Kiss me."

Yeonjun immediately complies, his body already craving the billionaire's touch. He kisses Soobin back fiercely, his tongue slipping past his lips to tangle with the billionaire's in a dance of heated arousal.

His hands roam over Soobin's body, craving more contact. His need for Soobin consumes him entirely, leaving him completely vulnerable to anything the billionaire wants. Every touch and kiss only adds fuel to the fire, his body responding eagerly to Soobin's movements.

Soobin's lips claim every inch of Yeonjun's mouth, his hands working on positioning both of them. He's rough with his movements, his only focus on his need to be inside the biker boy.

He doesn't give him any time to prepare, sinking into him with one fluid motion.

Yeonjun gasps against Soobin's lips, his whole body shuddering at the sudden intrusion. He grips the billionaire's shoulders tightly, trying to adjust to the feeling of being filled. He can feel every inch of Soobin inside him, the initial discomfort quickly dissipating into raw, unfiltered lust.

"Please," Yeonjun begs as he's filled to the brim, his voice broken as he looks into Soobin's eyes. "Please... give me more."

"You asked for this, biker boy." Soobin growls, his hand coming up to grip Yeonjun's throat. He pulls him in for a brutal kiss as he begins to move, his hips snapping forward.

He's wild with lust, his movements rough and demanding. The sounds of their bodies coming together fill the space around them, the air hot and thick with their desire.

Yeonjun moans loudly, his body responding to Soobin's movements like a well-tuned instrument. Every stroke draws out pleasure that threatens to overwhelm him, his whole body a vessel for his desire. He clings to Soobin desperately, his body moving to meet each thrust of his hips.

"More," he gasps out, his voice heavy with need. "More, Soobin... show me what you've got."

Soobin doesn't hold back, every inch of him driving into Yeonjun. He leans in to claim the boy's lips once more, his tongue pushing into his mouth in the same rhythm as his thrusts.

He feels the tension building in both of them, his whole world narrowing down to the man beneath him. "I'm going to make you mine, Yeonjun," he breathes out, his words a promise. "You're going to be screaming my name, begging for more... and I'm going to give you everything you want. And more."

Yeonjun's moans are swallowed by Soobin's insistent lips, his mind buzzing with pleasure. Every thrust brings him closer to the edge, his body feeling like it's on fire with Soobin moving inside of him.

"Yes," he groans in response to Soobin's words, his body shaking with need. "Yes, Soobin, please..." he begs, his words trailing off into panting breaths as the billionaire continues to drive him ever closer to a peak of ecstasy.

Soobin's eyes burn with desire as he looks down at Yeonjun, their bodies moving in perfect sync. He can feel the biker boy's body tightening around him, the signs of his impending release building in the tension in his muscles.

He leans in closer, his lips brushing against Yeonjun's ear. "You're so close," he murmurs, his voice a husky whisper. "Come for me, my sweet boy. I want to see you break apart."

Yeonjun can only nod, his words lost in a haze of pleasure. His whole body is wound tightly with tension, every nerve ending screaming with need.

With a final, hard thrust, Soobin pushes him over the edge and into oblivion. The sudden surge of pleasure hits him like a tsunami, white spots exploding behind his closed eyes. He cries out, his voice a broken gasp as he comes harder than he ever has in his life.

Soobin doesn't stop, his pace becoming erratic as he chases his own release. He kisses Yeonjun again, swallowing up the biker boy's breathless moans.

It's not long before he tumbles over the edge as well, a low grunt escaping him as he finds his release. For a moment, he loses himself in the blissful heat of Yeonjun's body, their bodies clinging to each other as they ride out their climax together.

The two of them remain still, their breaths coming in hard pants as they slowly come back to themselves. Yeonjun feels completely spent, every inch of his body humming with the afterglow.

He can feel the billionaire's heartbeat against his chest, a steady, comforting rhythm. He looks up at Soobin, a small smile on his face. "That was... amazing," he breathes out, his voice rough.

Soobin leans down to kiss Yeonjun softly, his lips gentle after the intensity of their previous actions. He murmurs against his lips, his voice a low rumble. "You're amazing," he whispers. "And now you're exclusively mine, Yeonjun." He pulls back to look at the biker boy, a possessive glint in his dark eyes. "That's a promise."

Yeonjun can't stop the grin from spreading across his face, his heart fluttering at the possessive words. "I'm yours, Soobin," he breathes out, his fingers tangling in the billionaire's hair. "And you're mine."

The weight of the promise hangs between them, like a thread binding them together. He leans into the kiss, his arms winding around Soobin, pulling him closer as their lips meet in a slow, sweet kiss.

Soobin gives a low hum of satisfaction, his own arms wrapping tightly around the biker boy. He can already feel his earlier hunger rising up again, but he knows they'll have plenty of time for that later.

For now, he just wants to hold Yeonjun close, to feel the steady thump of his heart beneath his ear. "Mine," he repeats, the word a whisper against Yeonjun's neck.

Yeonjun lets out a soft laugh, his fingers tracing lazy circles across the billionaire's skin. "Yours," he repeats, the word sending a pleasant shiver down his spine. He presses a kiss against Soobin's temple, his eyes flickering over the billionaire's face with affection. "And don't you forget it," he teases, the words light and playful. "I'm a lot to handle."

Soobin chuckles, pulling away just enough to look at Yeonjun. "Oh, I have no doubt about that, biker boy," he says with a grin. "But I wouldn't have it any other way."

He can't resist taking one more taste of those sweet lips, capturing them in another kiss. His hands move lower down Yeonjun's body, exploring every inch like he's marking his territory. "I can't get enough of you," he murmurs against the biker boy's mouth.

"Mhm, now get off though. You're all sweaty." Yeonjun huffs out a laugh, squirming away from him a bit.

Soobin snorts in amusement at the comment. He shifts his weight a little, not wanting to crush the biker boy beneath his body. "You're the one who made me work up a sweat," he teases, pressing a soft kiss to Yeonjun's neck.

Yeonjun giggles, tilting his head back to give Soobin better access to his neck. "Oh, I know," he teases back, his hands roaming over the billionaire's back. "It worked exactly as I planned." His eyes flutter shut for a moment, a soft sigh escaping him as he revels in the sensation of Soobin's lips against his skin.

"Biker boy, you are trouble," Soobin says with a laugh, his lips still tracing a path down Yeonjun's neck. He can't resist teasing him just a little more, sucking on the skin briefly before pulling away.

He looks down at Yeonjun, his eyes dark with a desire that hasn't faded. "You think we're done here?" he asks, his voice a low rumble. "This is just the beginning, sweetheart."

Yeonjun shivers at the words, his body already responding to the billionaire's touch. He doesn't need much more convincing, his hands already pulling Soobin's hips closer to his.

"I'm just getting warmed up, don't worry," Yeonjun breathes out, his voice low and rough with desire. His lips find Soobin's again, hungry and insistent as they kiss. "Show me everything you've got."

Soobin lets out a low growl, his lips moving with a renewed urgency. He responds to the biker boy's kiss with equal fervor, his hands roaming over Yeonjun's body like he's trying to map every inch of him.

"You better be ready, biker boy," he breathes out when they break for breath. "I won't stop until you're left wrecked and begging for more." He leans in to kiss Yeonjun again, a hot promise of what's to come. "And even then, I'm still not pulling out."

Yeonjun groans, his body arching into Soobin's touch. The billionaire's words send a thrill down his spine, his mind already buzzing with anticipation. He pulls Soobin closer, his hands gripping him like a lifeline.

"I'm ready," he breathes out, his voice a low rumble in his throat. "Don't hold back, Soobin. Show me what you've got." His lips find the billionaire's again, the kiss hard and desperate as he presses himself against him.

"Mhm, hold on. For the things I plan to do to you, we're gonna need a bed, baby." Soobin's lips curl into a slow smirk, pressing a side button in his grand luxurious car that signals his driver to start driving.

The words send a shiver down Yeonjun's spin, his mind already filling with the possibilities of what the billionaire can do to him in the soft comfort of a bed. He kisses Soobin harder, his hands still roaming over the billionaire's body.

"Take me home," he whispers against the billionaire's lips, his voice filled with a need that can only be described as sinful. His hips grind against Soobin's, the friction making him shudder. "I need you, now."

"I know, baby." Soobin grinned, kissing his temple. "But cover yourself up first. We're gonna reach my place soon and I can't have you walking outside butt-naked."

Yeonjun pouts a little at the billionaire's words, not wanting to waste a second of their time together. But he knows Soobin is right, that they can't waltz out of the car with nothing on.

He quickly slips on his clothes, the fabric clinging to him in all the right places. His eyes find Soobin's, the look in them dark with desire. "Okay, I'm ready," he murmurs, his voice hoarse with need.

Soobin gives the biker boy an appreciative glance, his eyes hungrily taking in his figure.

"You look ready to wreak havoc," he teases, his lips quirking up into a smirk. He pulls Yeonjun into another heated kiss, his hands sliding lower down the biker boy's back. He leans in to murmur against his ear, his voice a low rumble, "We're almost there, sweetheart. And then you'll be all mine."

Yeonjun groans at the sensation of Soobin's hands on him, his body already thrumming with anticipation. His arms slip around Soobin's neck, pulling him in for another fierce kiss.

"I can't wait," he breathes out against the billionaire's lips, his voice laced with a desperate need. His body moves in time with the car's motions, his hips brushing against Soobin's. He can feel himself getting harder again, the friction sending a hot thrill through him.

Soobin's hips buck at the contact, his breath coming out in a harsh rasp. He wants to give in, to strip them both and take what he wants here in the back of the car.

But he knows it'll be better to wait, to draw out the anticipation until they reach the bedroom. With a final nip at Yeonjun's lower lip, he reluctantly pulls away. "Patience," he says, his voice rough with need. "We'll be there soon, sweetheart."

The words send another shiver down Yeonjun's spine, his body responding involuntarily to the billionaire's voice.

"I've been patient," he breathes out, his voice ragged with desire. His hands continue to roam over Soobin, desperate to touch him in every way possible. "But I can't wait much longer," he whispers in the billionaire's ear. "I need you now." His hips push against Soobin's, the bulge in his pants growing more prominent with every second.

Soobin gives a rough groan at the sensation, his own body responding in kind. The heat between them is almost unbearable now, the billionaire struggling to keep himself in check. But he knows that the wait will make it all the more worth it.

The car finally comes to a stop, and Soobin quickly pulls away. "Come on," he says, his voice tight with need. He leads Yeonjun out of the car, eager to get inside and finally give them both what they crave.

Yeonjun shivers as the cool air hits him, his body yearning for the warmth of Soobin's touch. He follows the billionaire eagerly inside the mansion, his eyes roaming over the billionaire's form with hunger.

"Where do you want me?" he asks, his voice low and sultry. He wraps his arms around Soobin's waist, his hands teasingly tracing a path down to the billionaire's hips. "On the bed or up against the wall?" His lips brush against Soobin's ear as he speaks, his voice filled with promise.

Soobin groans at the suggestion, every word only adding fuel to the fire that burns within him.

"The bed," He manages to say, his hands tightening around Yeonjun. "I want you where I can touch every inch of you. But I promise, the wall is next on the itinerary."

He leans in to claim the biker boy's lips in another bruising kiss, his tongue delving into his mouth with a familiar kind of urgency. His hands travel down to grip Yeonjun's ass, pulling him closer against his body.

Yeonjun melts against Soobin's touch, his body responding to the billionaire's words with a desperate urgency. He returns the rough kiss with equal fervor, their mouths meshing together in an eager, passionate dance. His hips push against Soobin's, the friction only serving to heighten his need.

"I can't wait," he breathes out against the billionaire's lips, his voice filled with a mix of need and impatience.

And with that, he tugs Soobin forward, dragging him further inside the house and, more importantly, towards the bedroom.

Soobin's eyes are fixed hungrily on the biker boy. He can't get enough of him, his need growing more and more urgent with every step.

The second they reach upstairs, Soobin pushes Yeonjun up against a random wall, his body pinning the biker boy. "I can't hold back any longer," Soobin growls, his voice thick with desire. His hands go to Yeonjun's pants, eager to get them off.

Yeonjun gasps at the sudden roughness, the sound turning into a low moan as his pants drop to the floor. He wraps his arms around Soobin again, pulling him in for a fierce, needy kiss.

"I don't want you to hold back," Yeonjun breathes out, his voice low and hoarse with desire. His own hands begin to work on removing Soobin's clothes, his movements impatient and eager. "I need you, Soobin. Now."

Soobin's movements become more urgent at the biker boy's words, his own clothes getting tossed aside without a second thought, and then his hands are everywhere on Yeonjun's body, exploring every slope and curve with a frenzied hunger. His mouth moves to Yeonjun's neck, marking the soft skin there with a trail of kisses and nips.

"You want it rough?" Soobin growls in the biker boy's ear, his fingers teasing around his entrance. "Is that what you crave?"

As soon as Yeonjun shakily nods, Soobin grabs Yeonjun by his naked form and throws him over his shoulder and jogs off towards his bedroom unable to control himself anymore.

The sudden movement takes Yeonjun by surprise, a gasp escaping his lips as he's hoisted over Soobin's shoulder. He can't help the small giggle that bubbles up, his cheeks blushing from the position. He can feel the billionaire's muscles shift beneath him, and it only adds to the excitement.

As they enter the bedroom, Soobin tosses him onto the bed, a wicked grin on his lips. "You asked for rough, biker boy," he says, his voice filled with a dark promise. "Let's see how well you can handle me."

Yeonjun's heart races at his words, his body thrumming with anticipation. He lays back on the bed, his body stretched out before Soobin like a sacrifice.

He can feel the heat of the billionaire's gaze, the intensity of it causing his own desire to flare. "Do your worst," He breathes out, the words a challenge and a promise all at once.

And Choi Soobin has never backed out from a challenge.
