"Cut!" the director shouts from behind the camera. The pulsing base shuts off abruptly, leaving Seunghyun's ears ringing as long, flawless legs carefully remove themselves from around his waist. Running a hand self-consciously through his hair, he gives the beautiful woman a small bow of the head and she smiles, dazzling, in reply before joining the flock of models gathering around the coordinators. He breathes a sigh of relief and stretches his arms, still not trusting his legs enough to attempt standing after being under a full grown woman for a full thirty minutes through rounds of bad angles, weird facial expressions and eventually leg cramps. It's not without a little regret that he watches the models disperse as they wander in small sets of seemingly endless, naked legs back to the dressing rooms. But then something cold and mercilessly hard lands in his lap, sending him into spasms of pain while Yejun chuckles above him. He grabs the water bottle from his throbbing groan and goes to fling it back at his friend, but thinks twice and, shaking his head, unscrews the cap and takes a long swig. "You suck," he wheezes. He tries to stand up but ends up hobbling past the magnae instead, who says nothing but gives Seunghyun a light pat on his hunched back. By the time he reaches one of their dressing rooms, he's able to stand up straight. Someone runs out of the room past him holding clothes wrapped in plastic covers just as he passes through the door, only to come face to face with a shirtless and blissfully unawares Younghak. Suddenly he's right back to where he was before Yejun's rude water bottle interruption, staring at more unclothed flesh than his eyes can take in with one look and licking his lips. Younghak looks over as Seunhyung enters with a side-ways grin. "Hey, hyung," he says in that perfectly innocent way only Younghak himself could manage while being half naked. "Hey," Seunghyun replies huskily, clearing his throat and attempting a convincing smile. Younghak turns back around and continues to hum to himself as he removes his black pants, neatly folds them into a perfect square and sets them to the side. He doesn't notice Seunghyun's steady gaze eying up his back, his muscular legs, his ass, until he peeks over his shoulder as he pulls on his jeans and Seunghyun is right next to him. He leans his cheek against Younghak's warm shoulder and sighs. "You're warm," Younghak mutters and puts a hand to Seunghyun's face. His forehead creases with worry and Seunghyun feels a twinge of guilt because, damn, the boy could be cute. Seunghyun wraps his arms around Younghak's waist and shakes his head, still resting against the other's shoulder. When Younghak doesn't protest, but returns to shuffling through a pile of discarded clothes to find his t-shirt, Seunghyun frowns and bites his shoulder. Younghak jerks a little, looks a him with a slight smirk and returns to his quest, so Seunghyun kisses the spot instead, then kisses the spot above it, then yanks Younghak closer to plant a lingering kiss at the base of his neck. To emphasize his point, he presses flush against Younghak's side and grinds shamelessly against his hip. This time, when Younghak turns and smirks at him, there's something wicked in his eyes. He doesn't say anything, but runs his hands along the lapels of Seunghyun's black velvet jacket with that same smirk. After smoothing out the wrinkles, he slowly unbuttons the jacket and slides his hands inside to push it off of Seunghyun's shoulders, making Seunghyun inhale sharply and try to move closer for contact, only to be blocked by a firm hand to the chest. "Hyung," he chuckles. "You need to change." With that, he tosses Seunghyun a shirt from the pile. Seunghyun grunts and pulls it on quickly. After he changes his pants and Younghak finds his shirt, Seunghyun tries to storm out of the dressing room alone, but Younghak pulls him back into a tight hug around the shoulders. "We'll handle that later," he promises with a loud, smacking kiss on Seunghyun's cheek. Younghak takes one step through the door of the bedroom and he's shoved sideways onto the bed by Seunghyun, who doesn't bother to close the door behind him since their manger is busy with Jinchul in the foyer. He lets himself fall, laughing, and holds his arms out for Seunghyun as he climbs on top to straddle Younghak's legs, and Seunghyun remembers how graceful that woman must have looked when she'd done the same to him during the filming. There is an obvious difference from the filming, however, in that Younghak hooks his fingers in Seunghyun's belt-loops and arches his hips to grind against Seunghyun's. Something like a curse forms on his lips, but he doesn't hear it as he grinds back down desperately and pulls at Younghak's shirt with his hands, succeeding in yanking it off after a few fruitless tries. Younghak reaches out to help, but strange black marks on his palm catch Seunghyun's attention and he stop the hand mid-grab. There, neatly written in black ink, is a woman's name and a phone number. Scowling, Seunghyun looks questioningly to his friend. "Someone was busy during filming," he mutters. Younghak rolls his eyes and Seunghyun responds by spitting in his hand. Automatically Younghak grimaces and wipes the spit off on his jeans, and when he looks at his hand again, he rolls his eyes. Seunghyun grins victoriously at the now-smudged writing. "I got that for you, hyung," Younghak grumbles and wipes off his hand again. "That was the girl who, y'know, was riding you." With that, he winks and Seunghyun inwardly curses himself. Then his eyes wander over Younghak bare chest and he thinks that it's not exactly a catastrophe. He has excellent options. Younghak laughs while Seunghyun lightly runs his fingertips down the exposed skin. Their eyes lock as Seunghyun leans forward to kiss it in appreciation, but before he can reach, something grabs him around the waist and pulls him upright. "Hey, hyung," Yejun mutters into Seunghyun's ear. He gives Seunghyun an affectionate squeeze and buries his face against the back of Seunghyun's neck. He doesn't wait for a reply, but gives Seunghyun a quick kiss on the neck before tipping Seunghyun's face upward and locking their lips in a slow, lazy kiss. Meanwhile hands tickle at Seunghyun's sides and eventually finger the hem of his shirt. He hisses as Yejun feels up under the shirt with one hand, just barely brushing his nipple and sending chills down his spine. Then he feels something pull at his pants again, and groans as Younghak grinds up against him, the warm friction in his groin contrasting against the cool feeling of Yejun's hands on his skin. Without even realizing it, he lets Yejun pull his shirt over his head and Younghak's hands move from his jeans up to his hips. Yejun's tongue licks Seunghyun's bottom lip before exploring the rest of his mouth at a thoroughly slow pace that sends Seunghyun's mind reeling. He feels Younghak arch up again and is ready enough this time to match the movement, and the combination is enough to make Younghak let out a low moan which sends Seunghyun chuckling into Yejun's mouth. Yejun breaks the kiss and pinches Seunghyun's nipple, obviously pleased at the surprised jerk he gets in response. "You're so sensitive, Seunghyun-hyung." His mouth moves downward, biting across the curve of his neck and sucking on his shoulder. Seunghyun turns and smiles into Yejun's hair while he plays with Yejun's other earlobe with his fingers. Though he doesn't show it, Seunghyun feels the boy's heartbeat quicken through the shirt against his back. One of his biggest accomplishments was discovering the magnae's weak spot, and he still hasn't told Younghak or Jinchul about it. He feels Yejun smile against his shoulder as if reading his thoughts and the hands on his chest move to his jeans. Apparently Younghak's hands are already there, though, because Seunghyun out of the corner of his eye watches Yejun's hands get knocked away, followed by a low chuckle from the boy beneath him. Those hands, which Seunghyun had completely forgotten, undo his button and unzip his fly before he can take a breath and Yejun's hands join them to roughly push down Seunghyun's jeans and boxers together until they're halfway down his thighs. Before he has time to feel embarrassed, Yejun shoves him forward and he nearly crashes into Younghak below. He goes to yell, but then Yejun carefully moves Seunghyun's knees one at a time to allow for his jeans to be pulled all the way off. "He's so helpful when he wants to be," Younghak whispers into Seunghyun's ear. Seunghyun turns, grinning, and kisses him, wet and sloppy and more than a little distracted by the chilly dorm air on his lower half. He kisses Younghak again and subconsciously arches into Yejun's warm hands as they massage his lower back and spine. Another set of hands joins Yejun's, but grab his ass instead as Younghak grinds against him. The denim of Younghak's jeans is almost painful against Seunghyun's erection, but the slight burn only makes him gasp louder against Younghak's shoulder and thrust his hips again for more. Younghak slides a hand in between them and traces Seunghyun's length with his fingertips, making him visibly shudder. Yejun takes the opportunity to run his hands along the insides of Seunghyun's thighs while he bites hard onto his hip. "Christ," he mumbles against Seunghyun's skin. "I can't even imagine how slow you two would go if I weren't here." That being said, he retrieves a bottle of lube from under the mattress. Despite himself, Seunghyun tenses when he sees the little bottle waving menacingly in Yejun's hand. "You're one to talk," Younghak replies while running a comforting hand through Seunghyun's hair. "You're still dressed." Seunghyun hears the little bottle pop open and then Younghak is pulling him down into a kiss which is nice enough but not nearly enough of a distraction to keep Seunghyun from feeling Yejun press a cold, wet finger against his entrance. He resists the urge to bite down on Younghak's tongue as that painfully long digit presses all the way inside him. In that moment his entire body tenses up so much that his arms almost buckle beneath him and he doesn't even hear the bedroom door open. Yejun's voice is what alerts him, with it's nonchalant greeting, "Hey, hyung." Seunghyun had completely forgotten that Jinchul wasn't there and is suddenly very ashamed of his splayed position, not that Yejun would ever let him hide at this point. A second finger is forced inside as he grunts into Younghak still-moving mouth, and he hears Yejun continue to talk as if doing nothing unusual, "I think Seunghyun-hyung could use a distraction. Mind helping out?" He can hear the smirk in Yejun's voice and Jinchul's low chuckle that follows. The bed shifts and surprises Younghak, who apparently had managed to distract himself with the kiss while failing to distract Seughyun. He pulls away to stare at Jinchul, casually leaning in between the two of them to kiss Younghak himself, who's hesitant but not unwilling as his eyes flutter closed. Seunghyun is surprised, too, and feels just a little ripped off, that is until Jinchul skims his hand down Younghak's chest to play with his nipple. Younghak jerks and moans, and the sound goes right to Seunghyun's cock, making it twitch and successfully forcing the invasive feeling of Yejun's fingers inside him from his mind, at least for the moment. He watches, entranced, as Jinchul's fingers drag slowly down along Younghak's skin, disappearing beyond Seunghyun's line of vision into the space between Seunghyun and Younghak's bodies. Knuckles brush against his erection and his mouth drops open, but Younghak's sudden gasp shocks away any sound he'd intended on making. Jinchul laughs against the spot just below Younghak's throat, where he'd been steadily sucking a bright red mark onto the skin. Jinchul says something, too, but Seunghyun doesn't catch it as he's stretched by a persistent third finger. He squeezes his eyes shut and swears to make Yejun pay for this next time. Yejun's fingers push deeper mercilessly as Seunghyun's fingers cling to the sheets beneath him so tight his knuckles turn white. He can hear Younghak panting, and as much as he loves that sound it's not enough to keep him from cursing and grinding his teeth. For a second Yejun relents, but the reason why becomes clear as Younghak moves a little underneath him followed by the rustling of cloth until Yejun yanks something away and tosses it away. Apparently, that something is what's left of Younghak's clothing and Seunghyun can feel the warm heat of the younger boy's skin on his. Then Yejun returns his attentions to Seunghyun and he moves his fingers just enough to hit the bundle of nerves he'd been searching for, making Seunghyun cry out and surprise Younghak and Jinchul. There's a warm hand on his shoulder that plays along his collarbone. "Sounds like someone is ready," Jinchul's warm voices muses and it's only then that Seunghyun realizes that his eyes are still closed. He blinks them open to find Jinchul smirking at him with dark eyes. He leans forward and gives Jinchul a quick, fierce kiss followed by a small smirk of his own. "I'll take that as a yes," the leader chuckles and rolls to the side and off the bed. Seunghyun stares into Younghak's flushed face and barely even has to pucker his lips before Younghak lunges forward for a kiss. There's another faint rustling behind him and then all too quickly Yejun's fingers retreat. He winces and attempts to turn and cuss out the magnae, but Younghak holds his face in his hands and won't allow it, so he sucks on Younghak's tongue and decides that it's not worth it anyway. Younghak moans into his mouth, but Seunghyun knows better than to take credit for it and sure enough he suddenly feels Yejun's hands on his hips. He's guided back until he feels Younghak pressing against his entrance. Younghak's hands replace Yejun's and, taking a deep breath, Seunghyun pushes down and lets Younghak fill him, inch by inch. It hurts so badly that tears form at the corners of his eyes, but he hears Younghak make another of his signature choked groans that never fail to make Seunghyun's cock throb painfully. He moves his hips just enough to tell the boy beneath that he's ready, and Younghak too readily forms a tight hold on his hips and thrusts deep inside. What he loves about Younghak is that he's never afraid to take the initiative, that he never minds setting the pace when Seunghyun feels liking throwing his head back and letting someone else do all the work. Unlike Yejun, Younghak never wants to go slow, never teases, which as wonderful as it can be to be teased, Seunghyun's temper can't stand it and Yejun always, always wants to tease. Yejun might make fun of Younghak for going too slow during foreplay, but he'd never dare doubt what his best friend is like when he lets go. Then again that is probably why the four of them always end up arranged this way, because the only person who can drive Yejun to the point of forgetting his need to tease is Jinchul, who can only be slowed down by how much he enjoys Yejun's teasing. Seunghyun straightens until he's fully sitting up and relishes the dull ache of Younghak's thrusts pushing deeper and deeper into him. Younghak's nails dig into his skin, leaving bright red scratches that Seunghyun knows will sting later. A smile forms on his lips as he imagines accidentally brushing against one of those marks, hissing in pain, and getting hard a second later as he remembers this feeling. Something moves beside him, brushing his arm, and he opens his eyes just in time to see Yejun fall back onto the bed, fully naked, next to Younghak who is far too gone to notice. He can't help but wonder what he's missed as Jinchul moves into view, also naked, giving Seunghyun a quick wink before returning his attention to the boy beneath him. "Suck me," Yejun orders with haughty confidence, his hands playing in Jinchul's hair. "Excuse me?" the eldest asks with fake annoyance, but he's already moving downwards after giving Yejun's stomach a quick bite. "Just do it," Yejun fake whines and hums in satisfaction as Jinchul takes his erection in his hand and strokes it. At that moment Younghak arches up into Seunghyun at just the right angle to hit that beautiful spot and Seunghyun gasps and grits his teeth. He can barely hear Yejun's quiet moans over his own unrestrained, desperate pleas and Younghak smirks at him and purposefully hits that spot over and over. He feels a tingling burn start in the pit of his stomach, spreading all the way to his toes, but he can feel that Younghak is close, too, and he can't help but make it a competition. But then Younghak wraps an arm around Seunghyun's waist and sits up, continuing to move and he's so deep that Seunghyun thinks he might lose this once. His arms cling to Younghak's shoulders in a needy way that he knows Yejun will make fun of later, but at the moment feeling Younghak's hot, sweaty skin against his is the only thing on his mind, and Younghak's ragged breathing, getting steadily faster and laced with small, almost imperceptible moans is just enough motivation to keep him holding on. He peeks an eye open and watches Yejun's face, contorted in pleasure, and smiles at how that perfect mouth is, for once, so completely incapable of forming a sarcastic remark. He has his knees bent, hands holding them in position as Jinchul thrusts into him at a pace that has Seunghyun moaning a little as he watches. He grins in triumph when he hears Younghak gasp and grunt into his ear, giving a few final bucks until he's breathing slow and heavy against Seunghyun's shoulder. Seunghyun kisses his temple affectionately and sings into his ear, "I win!" Luckily Younghak is too easy-going to take offense, because had he dared said that to Yejun or Jinchul, he'd probably be in for the worst night of his life. Younghak, though, just smiles dreamily, kisses Seunghyun's cheek and buries his face into his neck, kissing him there, too. Only after a bit of fake struggling against Younghak's comfortable arms, which he's half tempted to curl up in and jack himself off while the boy holds him, is Seunghyun able to detach himself and clean the mess running down his thighs. As soon as he returns to the bed, where Younghak is dozing in the corner, he hears Yejun make an all-too familiar grunt and he arrives just in time to watch Yejun stroke himself through his orgasm over Jinchul shoulder. Yejun promptly shoves Jinchul back with a dazed, yet smug smile and rolls over to join Younghak on the other side of the bed. Younghak pulls Yejun into a tight hug and covers his mouth in his messy post-coital kisses which only Yejun has the patience to handle because he's so used to them. Seunghyun doesn't get much time to admire the pair, though, because Jinchul grabs him by the arm and pulls him back down onto the bed. He lands on all fours and barely has a chance to laugh before Jinchul pushes into him, and his arousal returns as quickly as it had faded. He inhales sharply and grips the sheets tightly as Jinchul pounds into him without bothering to wait for him to adjust. Seunghyun wraps his fingers around his erection and begins to jerk himself off at a similarly breathtaking pace, hating himself for not letting himself come earlier. Jinchul comes first, his hands leaving even more bruises on Seunghyun's hips as he lazily thrusts into him and groans. Seunghyun finally finishes into his hand a moment later, the whimper escaping his lips a mix of sweet satisfaction and almost painful relief. He hisses as Jinchul carefully pulls out and moves away from the bed. He rolls onto his side and gratefully accepts the box of tissues Jinchul hands him upon his return. Once clean, Seunghyun crawls, tender and sore and still aching in certain areas that will take at least a week to recover, over Yejun's long, soft body to snuggle in between the magnae and Younghak. Arms wrap around him from both sides and he rests his cheek on Younghak's shoulder. Somewhere to the side he can imagine Jinchul crawling in to curl around Yejun and he sighs happily. The last thing he hears before drifting off is Younghak's low, rumbling snoring in his ear.
