Work Text:
Changbin’s body was thrumming with adrenaline. He felt so alive on stage, he knew they all did. The way the attention brought him to life, and his blood raced through his body. He was hot, sweaty, and felt like he was on fire. They walked backstage, having to wait for everyone else to perform before they could leave the music stage and go back to their dorms. Changbin knew he should rest, go to bed and get some much needed sleep, but he was just too worked up. He thought he was going to go straight to the gym, work off all the energy he still had racing though him when he finally got home.
Changbin headed to the table at the corner of the room, grabbing a bottle of water, and looking over at the other kids, all of them looking worked up and energised as well. Jisung dropped into a chair, Felix flitting over to sit heavily on him and Minho hovered close by, his eyes never leaving Jisung. Chan leant against the wall, smiling as he talked to the people he knew who were also performing today. Hyunjin was messing up Jeongin’s hair, much to the stylists annoyance, as they glared at them from their station. Changbin frowned, unable to find Seungmin amongst the mingling bodies in the large room. Changbin was sure he had left the stage, he could be hard to wrangle at times, but he couldn’t imagine him staying in front of the audience all alone.
“Catch!” Seungmin’s voice rang out next to him. He turned to see Seungmin’s devilish grin as he threw a grape right at the centre of Changbin’s face. “Nice catch!” Seungmin said as he cackled.
“Calm down.” Changbin said, scowling at him.
“No.” Seungmin said with a frenzied smile as he picked up a slice of bell pepper and threw it at Changbin’s face.
The vegetable hit his face with a wet slap, leaving a smear of red juice as he fell to the floor. Changbin groaned and picked up the mess of food at his feet and walked over to drop them in the trash before dealing with whatever was possessing Seungmin. He bent over slightly to put the fruit and veg in the trash, and as he straightened up he felt his shirt pull back then he cried out as he felt the shock of cold slivering down his back and leaving him wet.
“What the fuck!” Changbin yelled out as he twitched back, spinning around as he reached back and tried to retrieve the ice from where it was still shocking him in his shirt.
“You need to chill!” Seungmin said, cackling and pinching Changbin’s side. “Get it? Probably not. You are not that bright, huh?”
“Listen here, you fucking brat. What the hell is wrong with you?” He asked Seungmin as he finally got the ice cube in hand and tossed it in the trash.
“I have to look at you. Isn’t that enough? You’re protein farts are gonna gas us, and you are asking what’s wrong with me?” Seungmin said, dodging Changbin’s arm as he went to grab him.
“You need to calm the fuck down.” Changbin said, walking after Seungmin who was hopping backwards away from him.
“You need to calm down! Here, have a water break!” Seungmin said, darting his hand out to grab a water bottle and throw it at Changbin.
The full bottle thankfully hit Changbin on his chest, it still hurt, but it wasn’t as bad as if he had aimed at his face. Changbin was losing his patience. He was used to Seungmin being a menace, especially when he was worked up, but he was bordering on out of control right now.
“Alright, you fucking rabid mutt!” Changbin hissed, darted his hand out to grasp Seungmin’s arm, holding him hard enough to keep him from escaping.
“Ahhh!” Seungmin cried out, like a petulant child. “Assault!” Seungmin looked at him with a dark glint of mischief in his eye. “You can’t do this. You are so big, and I am so small. It’s cruel.”
Then Seungmin went too far. He wound his arm back and snapped it forward to leave a stinging slap right on the centre of Changbin’s stomach. Seungmin giggled as the flesh jiggled at the impact, and Changbin grit his teeth. The sting of pain pushed Changbin out of his calm controlled state and into an overwhelming desire to control Seungmin instead of himself. Seungmin’s face froze in slight shock as Changbin’s expression darkened, sneering a little as he moved a hand up to the back of Seungmin’s neck, and gripping him hard to scruff him.
“Hey! You can’t do this!” Seungmin said, pouting like he was just about to lose his favourite game.
“Watch me.” Changbin said, his voice deep and steady.
Changbin moved his other hand to press over Seungmin’s mouth, muzzling him as he moved his mouth close to his ear.
“Stop your fucking barking and come with me. You need some fucking training.”
Seungmin just blinked at him for a second before Changbin glanced around, making sure no one was watching them as he dragged Seungmin from the room. Seungmin was being compliant suddenly, and walking with Changbin without even trying to struggle or break free as Changbin hunted for a private place to deal with him. Changbin got a few strange looks as he walked down the hallway, and knew he needed to either take Seungmin somewhere away from others eyes, or give up his position of control. Then Changbin spotted the sign with Minho’s name on it. He glanced behind him. Minho had seemed occupied with monitoring Jisung’s antics, and so he probably wouldn't need it right now. Changbin gave Seungmin a warning look before he released his mouth, his other hand still firmly holding his neck, and opened the room that had been prepared for Minho.
Changbin closed the door behind them and stood in front of it as he released Seungmin, shoving him into the small room. Seungmin stumbled and huffed, turning to glare at him, looking about as defiant as a puppy refusing to sit. Changbin crossed his arms as Seungmin fidgeted on his feet, he opened his mouth, looking like he was trying to think of what to say.
“Well! So!” Seungmin huffed, pouting as he glared back at him. “What now?”
“That’s up to you. If you can behave yourself, we can go back. If you can’t…”
“If I can’t?” Seungmin asked, tilting his head, his eyes opening wide in what looked like hope.
“If you can’t… I’ll have to find a way to teach you how to be a good dog and do as you're told.”
“How will you do that?” Seungmin asked, shuffling towards Changbin.
Changbin was aware of a change of the atmosphere. He felt a tension in his core, his adrenaline crying out to be grounded into the body in front of him. Changbin felt his blood racing, and it was racing to one specific place.
“I think I will have to make you learn your place.”
“And what place is that?” Seungmin asked, close enough to touch now.
“Underneath me!” Changbin said as he reached out and took Seungmin in his hands, ragging him around and pushing him up against the door. Seungmin’s breath caught and he reached to grip Changbin’s biceps, his fingers digging into his flesh. “Is this okay?” Changbin asked softer, his tense frustration not enough to cloud his need to make sure this was welcomed and not actually harmful.
“Yes.”
“You say the word stop, or no, and I back off. No questions, no awkwardness. Got it?”
“Yeah… yes.”
“I don’t want to do anything you aren’t comfortable with, don’t actually want. But if I don’t hear stop or no, I am not going to back off until I’m done with you. Okay?”
“Fuck, yes! Please!” Seungmin squeaked, squirming where Changbin had him pinned.
“God, you really are just a pathetically desperate brat who need someone to fuck some manors into you, aren’t you?”
“Yes. Think you can handle it? I’m not sure you have it in you to break me in.”
“Oh? I’m gonna fuck you so hard you won’t be able to walk back on that stage.”
Changbin stared into Seungmin’s eyes, matching his challenging glare for a moment before he gripped his hip and spun him around, smashing his front against the door and filling the room with the loud bang of impact. Changbin pressed a palm between Seungmin’s shoulders, holding him effortlessly in place as he looked around the room. This was Minho’s room. He and Jisung had come in here for a nap earlier. There had to be lube and condoms here somewhere. Minho’s eyes landed on a small bag next to the pile of blankets that looked like a Jisung shaped nest and smirked.
“Don’t move a fucking muscle. Or I’ll tie you up like the unhousebroken pup you are.” Changbin muttered into Seungmin’s ear, smirking in satisfaction as he felt him shudder slightly before nodding.
Changbin lifted his hand from restraining him and stood behind him for a moment, checking he wasn’t going to instantly rebel, then he moved to grab the bag and look inside. Changbin smiled and nodded, seeing lube and condoms, and other items that he felt were less fair game for him to touch. Thinking he might even need to disinfect his hands if he did touch some of them. He took the lube and one condom out, placing the bag back down and trying to forget the other contents before placing them in his pocket and moving back to Seungmin, who had done as he had told and not moved from the spot he had left him. Changbin smiled and moved his face close to him.
“Good boy.” Changbin muttered, sliding his hands down Seungmin’s side, towards his pants.
Seungmin whimpered softly as Changbin’s hands worked on unfastening the buttons and zips that separated him from his skin. Changbin wanted to draw this out, to make Seungmin suffer a little, but his own pants were already uncomfortable with how hard he was. He dragged Seungmin’s pants and underwear down in one harsh movement, nodding at the gasp it drew from him. Changbin raked his nails down Seungmin’s pert, pale ass, growling a little as he felt the sudden urge to plunge deep into him right now, see how much he could make him scream. Changbin shook his head, remembering that Seungmin put on a strong front, but he was actually a sensitive guy, and while Changbin wanted to render him a whimpering mess, he would never even entertain a fantasy of hurting him.
“I’m not gonna go easy on you. Naughty puppies need a firm hand to learn.” Changbin said, squeezing Seungmin’s ass cheek harshly before slapping it lightly.
“Woof!” Seungmin barked out as Changbin’s hand impacted on his skin.
Changbin chuckled, delighted at how far gone Seungmin was already. Changbin quickly grabbed the lube out of his pocket and coated his finger before leaning his face close to him and sliding a finger between Seungmin’s quivering cheeks.
“That’s my good boy.” Changbin whispered as he pushed one finger into Seungmin’s tight hole.
Seungmin made the most debauched moan Changbin had ever heard as he started to plunge his finger into his depths. Changbin wrapped his other arm around Seungmin’s tiny waist, pulling him against him as he started to rut his painfully hard cock, still confined in his pants, against Seungmin’s hip. Changbin started to breathe heavily, his hand gripping Seungmin hard enough to bruise as his other hand rushed to push in a second finger to Seungmin.
“Ah!” Seungmin, gasped, arching his back as his fingers clawed the door.
“That’s it, you can take it. Show me how good you can be. Earn your reward.”
“I can take it! I want to be good for you.” Seungmin panted, dropping his face to the wood of the door as Changbin spread him open.
Changbin grunted, bucking his hips forward as he curled his fingers inside of him. Seungmin wailed and wobbled before starting to sink down the door. Changbin pulled his fingers out and stepped fully behind him before lifting Seungmin up by the backs of his thighs. Seungmin moaned as he dropped his head back on Changbin’s shoulder, his hand scrabbling to grip Changbin’s arms.
“Put this leg on the door to brace yourself.” Changbin ordered.
Seungmin obeyed, stretching one shaking leg out to press against the door, struggling a little against the pants that were bunched up around his legs. Changbin stepped closer to the door to make it easier on him before moving his hand back to push three fingers into Seungmin. Seungmin whined, his body trembling as Changbin rushed to get him stretched enough to take him.
Changbin was impressed at how well Seungmin held up, literally, as he finished opening him up. Once Changbin felt sure he had prepped him enough to not hurt him, he pulled out his fingers and gripped him around the waist before stepping back from the door. Seungmin yelped a little as Changbin walked them over to the couch on the other side of the room.
Changbin kept a hold of Seungmin’s waist as he dropped his legs to the floor, waiting until he was on his own feet before letting go. He gave Seungmin just a second to get steady before he placed a firm hand on his shoulder and shoved him forward, bending him over the arm of the couch. Changbin quickly unfastened his own pants, grunting as he brushed his hand over his aching cock. He made quick work of releasing his cock and rolling on the condom before coating himself in more lube.
“You ready to behave?” Changbin asked as he lazily stroked a hand over his cock.
“Yes!” Seungmin yelped.
“Going to be a good boy?”
“I’m good!”
“Want your treat?”
“Yes!”
“Okay… Beg.”
“What?” Seungmin asked, shocked as he lifted up to look back at Changbin.
“Good boys know how to obey commands. You want your treat. Now beg.” Changbin said, voice steady even though his own need was at a boiling point inside him.
Seungmin scowled, curling his lip as he seemed to be fighting all his natural instincts to bite back. Changbin waited, appearing more patient than he felt, looking at him impassively.
“Please.” Seungmin said, his jaw tensed, straining his voice. “I want my treat. I’ll be good, please. Give me my treat.”
“Hmm, that's good. What is the treat you want?”
“Are you serious?” Seungmin snapped.
“That’s not good.”
“Fine!” Seungmin huffed, dropping his body back over the arm of the couch as he gave up the fight. “Please, fuck me. Break me in, and make me cum. I want you to make me cum.”
“That’s better.” Changbin said with a smug smile as he gripped one of his hips and lined up the tip of his cock to Seungmin’s greedy hole. “Remember, I will stop if you tell me.”
“Don’t stop. Please.” Seungmin pleaded in a weak voice.
“Oh, that's my boy.” Changbin rasped as he jerked forward and pushed into him.
“Ngh!” Seungmin gasped as Changbin pressed the head into Seungmin’s crushingly tight hole.
“Fuck! Okay?” Changbin asked, struggling to hold onto his composure.
“Don’t stop! Please!”
Changbin nodded, even though Seungmin couldn’t see him, then kept moving into him. Changbin slid into him, not stopping until his hips pressed deep into the flesh of Seungmin’s ass. Changbin let out a deep groan, feeling all the tension shifting and moving to one focal part of his body, waiting to be released into the waiting hole he was buried into. He moved his hands up under Seungmin’s shirt, feeling the hot skin beneath.
Changbin gave Seungmin a few minutes to adjust before he moved his hands back to grip his hips, shifting his legs to ground himself.
“Ready?” Changbin asked, remembering himself before laying into him.
“Yeah. Please. Fuck, Changbin, I really need you.” Seungmin sounded fucked out already, his voice soft and vulnerable.
“You got me, I’ll give you everything.”
Changbin started with a brutal pace, snapping his hips and he started to pull out and drive back into Seungmin like he had been aching to do since they entered the room. Seungmin made the most heavenly moans of pleasure, high and whiney, rambling words that were unintelligible. Changbin felt his whole body giving in to fucking him, feeling like this was what he was made for. He was where he was supposed to be, buried deep inside of Seungmin.
The room was filled with the sound of skin slapping, and Seungmin’s cries of pleasure. Changbin didn’t even spare a thought for the people outside the door who might hear them. He didn’t spare a thought for anything else. He never wanted to do anything else. It was shocking to him how right this felt.
“Fuck! Seungmin! You feel so good!” Changbin praised, feeling his body starting to crest the wave of pleasure already.
“So good! Need you!”
Changbin moaned, Seungmin’s needy words affecting him more than he would have expected. Everything about Seungmin was affecting him more than he would have expected. Seungmin was perfect. Changbin faltered in his rhythm of fucking him as he realised just how much this meant to him. How much Seungmin meant to him. Changbin dug his fingers in harder, wanting to bruise him, wanting to leave his mark, let everyone know he was here. He was so close to his end, he knew he couldn't last much longer, but he wasn’t quite at his peak when Seungmin wailed loud and shuddered as he released over the couch.
“Fuck! That’s it! Cum for me!” Changbin grunted.
Changbin kept pounding into him, but when he noticed that Seungmin was whimpering a little and his legs were shaking Changbin pulled out, not wanting to push him into painful overstimulation.
“Huh?” Seungmin asked, looking back at him, eyes watery, as he clearly knew Changbin hadn’t cum yet.
“You did so well. Now, come here. I want you to sit.” Changbin ordered, stepping back from him before pulling off the condom.
Seungmin hummed as he scrambled onto his uneasy legs then dropped to his knees, eyes wide as he watched Changbin start to stroke over himself. Changbin grunted, feeling an overwhelming swell of arousal at the sight. Seungmin’s big brown eyes looked up at him, pleading and fond. When Seungmin opened his mouth, sticking out his tongue, it was enough to push Changbin past his limit.
“Fuck! Seungmin!” he cried out as he hit his peak.
Changbin grunted as he saw his cum spray out and coat Seungmin’s tongue. The ropes of sticky white landed on his tongue, dripping to his chin, then over his cheek, only just missing his beautiful eyes. The last drop made it to Seungmin’s tongue before Changbin let out a heavy breath and stilled his hand.
Changbin groaned as Seungmin placed his tongue back into his mouth and swallowed. Changbin dropped to his knees and before he even had a second to think about his actions, he was pressing their lips together. Seungmin whined before parting his lips, lifting his hands to grip Changbin’s head and keep him pressed against him. Changbin wrapped his arms around Seungmin and pulled him against him. They stayed knelt on the floor, kissing deeply as they both came down from their high.
Changbin finally realised he had to actually face reality and pulled away from Seungmin. He smiled at him, but stopped him when he swayed forward to try and capture his mouth again.
“Minnie, baby. We need to clean up. Then we need to talk. Can you do that for me?” Changbin asked softly.
“Okay.” Seungmin nodded.
“There’s tissues near the blankets, we will wipe your face, then the couch.”
Changbin took charge in cleaning them up, cleaning Seungmin of lube as well as the cum, then getting as much of the cum from the couch as he could before they adjusted their clothes. Changbin gripped Seungmin and sat them on the couch, pulling Seungmin into his lap.
“So…” Seungmin said, avoiding eye contact with him.
“So… I am not sure where that came from…”
“I’m sorry, it was all me. I shouldn't have-”
“But I’m glad it did.”
“Wait, what?” Seungmin’s head snapped to look Changbin in the eye, wide with shock.
“This was the best I’ve ever had. I’ve never felt like this when I’ve hooked up with anyone before. I don’t wanna freak you out, but I think I might have some feelings for you… you know, more than the bandmate, and friend kind.”
“No shit?!” Seungmin exclaimed, starting Changbin. “I am so fucking into you! I have been for so long! Why do you think I spend so much time trying to get your fucking attention?”
“Wait, what?”
“You are so fucking dumb.” Seungmin scoffed.
“I’m gonna let that one pass, but I’m being real with you here, so can you leave the brattiness out of it.”
“Yeah, I just… I’ve been going crazy for so long over you.”
“So… I guess you won’t be upset at me telling you I might want to do this again… And maybe some other things. Not just sex things, more feelings things.”
“You are such a sap.” Seungmin laughed, pulling Changbin in to kiss his smiling lips.
“Well what do we have here?” Minho’s voice broke them out of their intimate moment.
“Oh shit.” Changbin grunted.
“Oh, so we are animals with no self control when we fuck, but you get to do it. In our fuck room, no less?” Jisung squawked.
“It’s my room. Not our fuck room.” Minho muttered.
“All of your rooms are our fuck rooms!” Jisung insisted.
“Okay, yeah. Anyway, we need to be on stage again soon.” Minho said, turning to smirk at Changbin and Seungmin.
“Fuck, we need to see the stylists, quick.” Seungmin said, eyes showing the fear of going onto stage with traces of a cum facial.
“Yeah, let's go. We can continue this talk later.” Changbin said, kissing Seungmin once more before letting him get up.
“And trust, we are going to be talking about this later!” Jisung said, sounding overjoyed at the potential teasing in his future.
