Summery: Yoochun is unable to deny Changmin
Jaejoong, who Yoochun used to date, asks him to dinner one evening Changmin's shopping with friends. He readily agrees, needing to see a fresh face and possibly more. He needs to see someone other than his lascivious brother who's taken to strutting around the house in tight jeans and no shirt. He knows he's doing it on purpose, to tempt him, to entice him and Yoochun usually falls prey to his advancements.
It's killing him.
Every night he goes into his room, every time he closes his eyes, every time he licks his lips he can see him, he can taste him.
It's killing him.
Everything about it is wrong and it doesn't go unpunished. Yoochun prays for forgiveness in the dark, hopes the wicked urges that claw at his body whenever he sees Changmin, go away.
He wonders if people know. Perhaps he should wear a letter, a blood red I in the center of his chest that warn people he's filthy in sin.
Yoochun knows he'll have to stop one day, though each time Changmin pleads with woeful eyes and persuasive smiles, he can't stop himself.
Because he wants it just as much.
Sometimes he thinks he wants it more.
"You look good," Jaejoong smiles behind his beer bottle and Yoochun can feel his eyes skimming over him, like a scanner. He smiles and the excitement mounts in his stomach.
Jaejoong, who is far too independent and self-absorbed to maintain long term relationships, managed to date Yoochun for a good few months before breaking it off. Yoochun tried to hate him but the feeling was mutual and he couldn't even bring himself to sever the ties of friendship especially since it was their friendship that lead them into the doomed relationship to begin with.
Now it seems like they've converged into something sort of like friends with benefits.
"So do you," Yoochun sets his empty bottle down and waves the waitress over. He thinks it's time to take things back to his house, maybe his room, revisit some of the good old days, but more importantly redeem his soul from the trespasses of Changmin. "You wanna go back to my place?"
Jaejoong nods with a knowing smirk and finishes his drink. "You still at your parents?" he asks and Yoochun nods throwing down a few bills to cover the empty bottles on the table and remaining pizza which now looks too unappetizing to take with them.
"It's cheap," he answers and stands with a grating scratch of his chair on the hard floor. Jaejoong gets to his feet gracefully and Yoochun notices how other people watch him. It was always something he hated, knowing other people wanted him. Jaejoong is too good looking for his own good and too hedonistic to refuse anyone. It was one of many reasons it just couldn't work out.
"Let's get out of here," Jaejoong slithers beside him and curls his fingers into his palm, winking at the cute bartender behind the bar. Yoochun reminds himself, he has no obligations or right to feel jealous, but it does sting, just a little. It makes it worse when he knows Changmin would never look at anyone else in the entire room. His focus would be on him, all the time, every hour, every minute until everyone just gave up.
That awareness only encourages Yoochun's decision to take Jaejoong back to the house and have his way with him until he can't stand anymore.
While Jaejoong drives, Yoochun gives him a blow job.
He thinks of Changmin and when Jaejoong cries out loud behind the closed windows and dark street lamps Yoochun remembers it's not him and almost chokes.
He's pinned against the cushions of the couch, Jaejoong kissing him, his mouth aggressive, his tongue sinful in its intrusion and Yoochun groans.
"Take your pants off," Jaejoong presses against his lips as his hands undo the button of his jeans with masterful ease and Yoochun bites his lips in anticipation. Their shirts are strewn on the floor haphazardly and Yoochun fumbles as he slides his jeans over his hips and Jaejoong slinks down between his legs in lustful urgency.
He's about to come when he hears the door open and Changmin's laughing voice sounds like an ear piercing alarm through the empty house.
"Stop," he groans but it's too late and he shoots with a loud cry into Jaejoong's mouth and a full body shudder that has every nerve ending in his body sparking with pleasure.
Jaejoong sits up, wiping his mouth, licking his lips with a smile and Yoochun pulls his pants up in a hurried jerk just in time to see Changmin and a boy he doesn't recognize walking through the hall.
"Hyung, I'm ho-" he calls out and stops walking when his eyes land on him. His smile falters and Yoochun flushes guiltily when his eyes examine the scene in front of him.
Changmin's gaze dances between him and Jaejoong. Jaejoong settles his arm around the couch, sitting with an innocent look on his face as he smiles up at him.
He doesn't know why but it's almost painful to see the disappointment that sweeps along his eyes. If he didn't know any better, he looked like he was about to cry and it clenches at the strings of his heart.
"Changmin. You. You know, Jaejoong," Yoochun shakes a little as he reaches for his shirt and throws it on. Changmin's friend is staring at them curiously and it leaves him feeling a bit naked.
Changmin's eyes narrow dangerously before brightening up in fake enthusiasm, "I do," he smiles and bows slightly, never taking his eyes off of him, "nice to see you again, Jaejoong," he says and reaches for his friend's hand before looking accusingly at Yoochun. "We're going to my room," he tells them both and Yoochun nods, watching them leave in a rush.
He can feel Jaejoong's eyes on him as Yoochun follows Changmin and his friend up the stairs until they disappear completely from his sight.
"He's grown," Jaejoong comments with a wicked glint in his eyes and Yoochun sighs, running his hands along his flushed face. "If he weren't you brother I'd try-"
"Shut the fuck up," Yoochun bites and throws Jaejoong's t-shirt at him; he laughs as he slides it back on and Yoochun glances briefly towards Changmin's room. "He's a kid," he mutters and it pains him to remember it.
Jaejoong nods as he starts crawling towards him. Yoochun watches him and feels a smile creeping over his lips, Changmin gone from his mind, if only for a moment. "Maybe he's got the right idea," he whispers into his ear, his hand running down his chest, across a firm nipple that leaves Yoochun breathless.
Yoochun kisses him and tries not to think or remember the look on his brother's face.
"My room," he mummers against his mouth and Jaejoong nods, touching him between the legs, getting him hard all over again.
Jaejoong tends to be clingy after sex.
It's really the only time he gives up control and Yoochun holds him in his arms while Jaejoong runs his fingers up and down his bicep. They're back in the living room watching television, some stupid movie that's playing in the late hours.
"This was fun," Jaejoong smiles softly and looks up at him. Yoochun nods and turns his eyes away when he hears a door open, followed by the loud sounds of his brother and another voice.
His eyes follow the sound and soon he sees Changmin, his hand clasped in the strangers hand, their fingers intertwined and Changmin's without a shirt on looking royally pleasured.
Jaejoong looks up briefly as they walk by, ignoring them and although he knows Jaejoong has lost interest, Yoochun can't seem to his take his eyes off of him.
He watches as Changmin leads him to the door, holds his breath when he sees them laughing and feels his heart pound when Changmin turns him around and kisses him, full on the mouth, in front of him. With purpose.
Completely on purpose.
Yoochun can't stop watching, thinks he sees the slide of their tongues when Changmin tilts their heads at an angle that's hit with perfect lighting and feels like he's going to be sick when Changmin opens his eyes and pierces him into a locked and tormenting gaze.
He forgets about Jaejoong as he can't look away.
Changmin kisses the stranger long and just the way Yoochun first kissed him.
He knows it, he can feel it.
He feels his heart beating angrily in his chest as a rush of insolent heat washes over him. Changmin grins after a few more seconds acknowledging that he's accomplished what he set out to do and closes his eyes to finish it.
Yoochun wishes he had the power to shoot lasers with a gaze. Changmin's friend would have two smoking holes in the back of his head if it were possible.
"I should be going soon," Jaejoong speaks after awhile and Yoochun makes an indifferent noise as he continues to keep his eyes on his brother whose roaming hands can't seem to stay put on his friend's shoulders.
He wants to rip Changmin's hands off.
"I'm going to the bathroom," Jaejoong says and sits up, he glances over at Changmin and smirks with a quick quirk of his lips before he gets up and it leaves only three of them left. Yoochun, Changmin and the stranger he never wants to know the name of.
"Changmin, come here," Yoochun calls out suddenly, without warning and watches as Changmin finally pulls away.
Their eyes lock and Yoochun shudders ungracefully, glad Jaejoong is not on top of him anymore.
"I'll be right here, Hyung," he calls out and Yoochun doesn't have to see him to know he's smiling.
The sound of a door closing rings like bells in Yoochun ears and he turns his eyes to see Changmin strutting towards him with a triumphant glint in his eyes. "Yes?" he asks as he comes to a stop behind the couch and his hands fall easily against the soft material.
"Who the fuck was that?" Yoochun asks bluntly before he can gather anything that resembles logic into his mindset. All he can see is red and Changmin leans down slowly, until his mouth is brushing his ear.
"A friend," he whispers and licks painstakingly slow at his ear before standing straight up.
Yoochun holds back the searing remarks of insult, but his hands clench in remembrance of his insolent tone. He swallows the jealous urge to explode and looks away. "It's late, you should go to sleep," he says instead and grabs the remote.
He can feel Changmin's eyes on him, radiating with something Yoochun doesn't want to acknowledge.
"Is there anything else?" he asks softly, seductively and Yoochun lets it run down his back in prickling agitation.
He hears the water running in the bathroom and knows Jaejoong will emerge soon after so he looks back at his brother who's standing gloriously in front of him. "Yeah," he breathes heavily, "don't ever do that again," he tells him and the door opens and the ray of light that slides through the darkened hallway flickers off.
Changmin nods. "Yes, Hyung," he licks his lips and leaves him.
Yoochun turns off the television in time to see Jaejoong walk around the couch, bending to grab his wallet and keys.
"That kid is dangerous," he says to break the silence and Yoochun glares at him.
"Jaejoong," he warns dangerously and Jaejoong laughs holding his hands up.
"I'm just saying," he adds and looks around before sighing, "walk me to my car," he finishes and helps Yoochun up with a forceful pull.
Among the singing night and shinning stars Yoochun kisses Jaejoong, it's rough and almost forceful. He presses him against the driver's side door and scratches his neck as he tries to vanquish the image of Changmin from his mind.
"Ok," Jaejoong laughs and pushes him again. "Ok, I've really got to go," he kisses him nicely on the lips and Yoochun nods, giving him a tight hug. "Call me," Jaejoong asks and Yoochun slides his hands into his pockets, shivering, from what he hopes is the cold.
"I will," he looks down at the ground.
They kiss one more time but it's sweet and Yoochun forces himself to think only of Jaejoong.
When he's too far gone and out of sight Yoochun walks back into the house, locking the door behind him.
It's eerily quiet, his parents are on vacation, returning in the morning and he turns all the lights off.
As he climbs the stairs he tries not to remember the kiss Changmin threw in his face as he walks down the hall.
He glances over briefly at the slice of dim light that peeks from the opening of Changmin's door.
He doesn't want to but it beckons him and before he can stop himself he's moving slowly towards Changmin's room, making sure to not raise a sound.
As he gets closer he can hear heavy breathing and Yoochun feels his heart drop straight down into his stomach.
He sees Changmin through the sliver opening, his hand on the doorknob.
He's lying in bed, his jeans a pile on the spotless floor. His eyes are closed, the blankets a rippled mess around his naked waist and the supple folds of his lips are opened slightly as each harsh breath releases in arousing beats.
Yoochun grips the doorknob, pressing himself against the opening as his eyes focus on the steady movement under the blankets.
Changmin's free hand moves up his chest, gliding over his skin in luscious sweeps that stir heat between Yoochun's legs and he bites his lip.
He's slow, savoring the feel of touching himself and when Yoochun's sees the tension crawl beautifully across Changmin's face he knows he's close.
He holds his breath, his palm sweaty against the warm doorknob and he clutches at it, fighting with the temptation to touch himself.
Changmin comes suddenly with Yoochun's name on his lips and he frees the doorknob in horror.
"Hyung," he hears the strangled call and Yoochun backs away slowly, holding his breath until he's in his own room.
He can still remember the look of release on Changmin's face as he climbs into bed, his arms and legs like jelly, his heart pounding.
He can still hear his name coming from his lips.
And he doesn't stop the shaky hands that undo his pants.
Doesn't stop from touching himself.
Doesn't stop from picturing Changmin.
Doesn't stop the burning tears that slide down his cheeks when he comes.
Changmin corners him in the bathroom, closing the door behind him and locking it.
Yoochun turns the faucet off and ignores him, walking to the towel rack to dry his hands. "You were brought up with manners," he tells him slowly, avoiding his face. "You knock before you enter a room," he says and runs his trembling fingers through his hair.
Changmin doesn't say anything, even when Yoochun finally looks at him. His eyes are amber stones of burning lust and seduction Yoochun is unable to ignore.
"You heard me, Hyung," he says softly and walks to him, closing the distance between them.
Yoochun hopes for an escape route, his eyes scanning the minimal surface. He doesn't find any and Changmin's standing before him, trapping him into an intoxicating gaze that leaves him almost breathless.
"I don't know what you're talking about," Yoochun side steps but Changmin follows like he's reading his mind.
When Yoochun moves to the side Changmin throws a long arm in front of him, his hand pressing into the wall of the shower. "Did you see me?" he asks temptingly, his mouth quirked into a devious smile and Yoochun wonders where he learned it from.
Yoochun can feel the demons twisting at his insides and closes his eyes to collect himself. "Changmin," he says but his brother is running his hands through his hair, curbing him to something completely unwanted but desperately seeking. "Why are you doing this?" he asks a little too submissively to the touch.
Changmin smiles, "Because I think about you, Hyung," he answers with heated breath, "everyday. All the time," he leans in and Yoochun can smell the fresh scent of toothpaste on his breath.
He wants to push him away, throw him against the wall and leave the bathroom. Just get away from him.
From the temptation that riddles his tormented body, his desecrated heart, his wavering soul.
"Don't talk like that, Changmin," he pleads weakly, knees buckling to the very closeness of their bodies.
"You taught me to tell the truth," he whispers impossibly close, his eyes dark and stimulated in desire, "I want you to know the truth."
He can feel himself collapsing under him.
"One kiss, Yoochun," he whispers into his ear, pressing his chest against him. "That's all I want." He slides his tongue along his earring and sucks at it like a wonton slave.
The tingles ravish his body while Changmin slides a hand against the small of his back, electrifying every sensation. "Stop it," he manages to wheeze out but it's difficult with Changmin kissing his neck, his fingers curling around his shirt, pulling him closer until their bodies melt into each other and one can't distinguish were the other starts.
Changmin laves delicately at the side of his mouth, his lips moving achingly slow until Yoochun can feel the heated pleasure.
Until he can't take it anymore.
He kisses him. Hard. His hands cupping his cheeks, holding him still, his body running with wild sensations he's want to ignore.
Changmin whimpers against his passion and moves them until Yoochun hits the wall, but he feels no pain, all he can feel, taste, touch is Changmin who's pinning him rightfully in place.
"Touch me," he begs between breaths of air and takes Yoochun's hand, guiding it for him.
Yoochun groans a little when he feels Changmin's arousal, his hands applying the right amount of pressure that has him gasping into his mouth and squeezing against him in undulating pleasure.
"Like," he kisses him hard, "like that," Changmin whimpers and jerks his hips wantonly. "Hyung, please," he pulls away and looks Yoochun dead in the eye, piercing into his burning soul and Yoochun just lets himself go.
He wants to no matter how bad he feels, no matter how wrong it is.
He knows deep down. He wants to.
Yoochun flips him around, pushing Changmin's back against the wall, his hand snapping the button of his jeans with masterfully nimble fingers; he unzips his jeans and feels him. His other hand comes to Changmin's mouth and covers it, looking at the door quickly, over his shoulder. When he turns back to his brother his eyes are needy and he's tonguing his palm. "Don't make any noise," he warns him and Changmin nods as Yoochun slides his hand into his jeans, until he can feel the thick heat, his fingers curling around him.
Changmin gasps as Yoochun replaces his hand with his mouth, breathing in every single moan that escapes.
Yoochun strokes him slowly, prolonging the pleasure.
He touches him, squeezes gently, sliding his fingers up and down, just the way he likes it and when Changmin shudders against him he knows it's working.
"Hyung," Changmin moans grabbing his face, weaving his hands through his hair, kissing him violently, biting at his mouth but Yoochun's hand doesn't skip a beat.
When he can't breathe anymore he pulls away and stares at Changmin's face, his head rolling against the wall, eyes closed.
"Kiss me," he begs softly, opening his eyes with tempting lashes, dark and stimulated. "Like the first time," he requests with baited breath.
Like the first time.
Yoochun licks his lips and uses his free hand to run down his cheek, feeling the warmth of his skin cupped in his cheek. Changmin nuzzles eagerly making soft pleading noises until Yoochun kisses him.
"Now open your mouth a little for me," he whispers and Changmin lips part enough for him to slide his tongue in.
Like the first time it's slow and delicate.
His hand stops for a moment and Changmin groans in his throat until Yoochun allows himself just one guilty smile before sweeping down in swift, hard friction to the base.
Changmin's shoulders tense and Yoochun knows he's close.
He quickens his pace and Changmin's soft pants curl around his ears in syncopated beats.
"Please, Hyung," he shudders again and opens his eyes, full of greed and lust and everything they shouldn't be.
It's his brother and he's getting him off.
Before he can scold himself with silent words of damning rhetoric he flicks his wrist one more time and Changmin chokes loudly, slumping against his body, his release warm and sticky against Yoochun's hand.
They don't move and Yoochun slides his hand out slowly.
"You ok?" he asks softly and Changmin's head nods against his shoulders, riding out the remaining waves of pleasure before Yoochun moves away and Changmin stumbles a little, his hands shaky as he starts to zip up his jeans. Yoochun walks to the sink with heavy foot falls and refuses to look at himself in the mirror. "Not yet," he tells Changmin flipping the water on. Changmin shuffles slowly over, biting his bruised lips and he looks amazingly satiated.
"Yoochun," he whispers, leaning against the counter for strength. "I love you," he turns his soft eyes to him and Yoochun feels his heart clench painfully in his chest.
He washes his hands and grabs a cloth, soaking it with warm water. "Clean yourself up," he hands it to him and the bright lights of his eyes dim ever so slowly as he lowers his head and Yoochun moves away to the door.
Before he can leave Changmin calls for him a little pained and he doesn't think he can take it. "What, Changmin?"
He looks close to tears, gone is the prowess of a predator and he looks like a kid who just had his innocence stolen from him. "Do you hate me?" he asks carefully and it rips at Yoochun's heart.
"No, Changmin, I don't hate you," he answers with a frown before he leaves and closes the door behind him.
He hates himself.
