Seokjin was kind of the sex outlet for Bangtan, and Seokjin didn’t really mind. They were all men in their 20s. Except Jungkook, who was still a minor. But in any case, he didn’t mind. He understood they came to him because he was pretty enough and vocal enough.   Namjoon liked him on his back: liked Seokjin’s legs tight around his waist as he fucked gently into him, whispering sweet nothings and perfect with aftercare. Yoongi liked him on his fours, would never let him touch himself and would get him off just by fucking, talking dirty the entire time but so sweet afterward even though he pretended he wasn’t. Hoseok was sweet the entire time, making corny jokes to keep Seokjin distracted from the intrusion at first and all chaste kisses and playful tickles. Jimin liked leaving hickeys everywhere he could get his mouth on, leaving trails of kiss marks down his inner thighs and down his stomach as he pushed into Seokjin. Taehyung came at him like he was about to eat him alive, almost violent in his sex and all hungry, open- mouthed kisses.   Jungkook..   Well, Seokjin didn’t know how Jungkook was.   Jungkook hadn’t really shown interest in having sex with Seokjin, and Seokjin was fine with that because he had enough on his plate (or in his ass) with five guys already. Not to mention that Taehyung and Jimin had insatiable sex drives. Plus, Jungkook was still a minor. A baby. He could technically go to jail for that.   “What’s on your mind?” Namjoon asked, pressing soft kisses to Seokjin’s knees. They’d had sex for over an hour. Namjoon was kind of really good at drawing out sex so it lasted longer and left Seokjin feeling like a puddle of melted chocolate. He had Seokjin’s left leg still on his shoulder so he could wipe Seokjin down.   “Sorry.” Seokjin smiled. “I was just thinking about Jungkook.”   Namjoon hummed in understanding. “He hasn’t shown any interest in you yet, huh?” His fingers gently swabbed tenderly at Seokjin’s thighs and let them down. Seokjin didn’t really think he could move. Sex with Namjoon kind of left him jelly limbed. “I wonder why. I see him looking at you.”   Seokjin blinked. “Really?”   “Yeah. With raw hunger.” Namjoon snorted. “If you thought Taehyung was bad, I don’t know how you’ll be with Jungkook. He looks like he wants to devour you.”   “Taehyung looks at me like that.”   Namjoon pulled the sheets up around them. They never had sex on Seokjin’s bed – it was on whoever’s bed that was claiming it. Namjoon’s sheets smelled musky. Seokjin liked it, but to be honest he liked Jimin’s sheets the best. Not that he’d tell Namjoon that. “Taehyung looks at you like he wants to put whipped cream all over you and nibble down on you. Jungkook looks like he wants to literally just dive at your throat.”   “I have noidea what that’s supposed to mean except that Taetae and Kookie might be cannibals.” He snickered when Namjoon rolled his eyes. “Anyway, he’s a minor.”   “I’m fairly certain he’s had more sex than –“ Namjoon paused. “I was gonna say he’s had more sex than you, but probably not. He’s definitely had more sex than you when you were his age. I assume you had none.”   Seokjin’s eyes widened. “You don’t think he’s a virgin?”   “Hyung, it’s Jungkook. He’s fucked before. Plus, he’s 17 already. I’m pretty sure he’s been fucking since the first year of high school.” At Seokjin’s scandalized look, Namjoon laughed. “Everyone in this industry’s pretty dirty. You knew that.” He nuzzled at Seokjin’s neck. “Not you, though.”   Seokjin laughed. “I regularly have sex with five guys. I don’t think I’m the epitome of innocence here.”   Namjoon’s arms snaked around his waist, tugging him closer. “But not for your benefit.” He took a big breath. Namjoon told Seokjin all the time that he loved how Seokjin smelled. And it wasn’t just Namjoon. Yoongi told him the same thing. Hoseok liked burying his nose in Seokjin’s hair. Jimin liked post coital cuddle sessions where he’d just smell Seokjin’s neck. Taehyung had once told him he wanted a bottle of Seokjin’s scent. (He wasn’t really sure if it was that nice or if Taehyung was just being Taehyung.) “We do make it enjoyable for you, though, right?”   Seokjin laughed and nodded.   --   After Namjoon mentioned it, Seokjin saw Jungkook looking at him literally like he wanted to eat him all the time. Seokjin kind of felt like a prey in the gaze of a predator. Also kind of like he was being stripped naked by Jungkook’s eyes.   But no matter what Namjoon said, Jungkook was still a minor. A baby at 17 years. He couldn’t even begin to imagine what sex with Jungkook would feel like. He thought about it once, lying below Jungkook, and he’d felt so guilty he’d physically shook his head to get the image out.   But months of Jungkook just staring at him passed and Seokjin figured he had to do something about it. “Kookie,” he said, one day when they were alone in the practice room. “If you want me, you can have me, you know.”   His heavily rehearsed speech fell dead on his lips when Jungkook turned toward him, eyes blazing. He pushed Seokjin backward, closing the gap between them with their noses brushing. “I’ll take you,” Jungkook whispered, “when I want to.”   A shiver spilled down Seokjin’s back and Seokjin nodded dumbly, remembering what Namjoon had said about Jungkook’s experience. A hand shoved under Seokjin’s shirt, cold against his heated skin, and he yelped. “I thought you didn’t want me.” He squeaked.   “That’s not what I said,” Jungkook responded, pushing his hand up higher to brush his fingertips against Seokjin’s hardening nipples. He grinned and Seokjin swallowed thickly. “Your body’s so responsive. Is it because of all the sex you’ve had?”   Seokjin only shook his head frantically and raised his hands to cup them over Jungkook’s hands, fumbling messily with it. “You’re a minor,” he whispered desperately, trying to wriggle away. “And we’re in the dance studio! What if someone walks in?!”   Jungkook laughed, pushing Seokjin’s shirt up. Jimin had left a trail of hickeys down his stomach, suckling at the soft skin there right next to his navel. Jungkook hummed. “Who did this?”   “Jimin..”   “And you’re worried about what they might think if they walk in?” Jungkook snickered. “I’m sure they’ll just turn around and leave.” He pressed his lips against Seokjin’s navel, licking around it before dipping his tongue inside. Seokjin almost jumped in surprise and Jungkook smirked, pressing a kiss to the wet skin before drawing back and moving upward. He pressed his tongue flatly on Seokjin’s chest, licking kittenishly at the skin between his collarbones before reaching down and squeezing down on both nipples.   Seokjin cried out and his hips tossed off the floor of the practice room. He squirmed, wishing he could at least somehow lock the door, but Jungkook squeezed again, making Seokjin twist under his hands. “I locked the door.” Jungkook snickered. “No worries. I knew we were going to be alone today.”   Seokjin stared. Jungkook had planned this. All this time he’d thought Jungkook was this innocent little maknae, but Namjoon had been right, after all. He squirmed under Jungkook’s hands as they squeezed down again. “The floor’s cold..”   Jungkook stopped and looked up, frowning a little. “Hang on.” He rose quickly, strode to where they’d tossed their jackets off, and pulled them under Seokjin. “Better?” Jungkook’s tone was gentler, the voice Seokjin was more used to, and Seokjin smiled. A little like Yoongi. Rough but still caring. Seokjin nodded and let himself relax.   He pushed his hands up Jungkook’s sleeves to grab at his bare shoulders, kneading his fingers into the muscles there. Jungkook wasn’t as built as Jimin was (none of them were quite as built as Jimin was, in fact) but there werelean muscles there rippling under Seokjin’s fingers. Jungkook leaned up to kiss him, raw and hungry and open-mouthed, and Seokjin shivered.   Jungkook didn’t waste any time delving back down onto his chest, kissing down to his navel. He stared disdainfully at the kiss marks Jimin had left and bit down hard on one of them. “Ow!” Seokjin scowled, squirming to push Jungkook’s forehead back. “What was that for?” Jungkook only glared and bit down lower, biting on each and every mark Jimin had left before. Seokjin only sighed in exasperation and dug his nails into Jungkook’s shoulders in retaliation. Jungkook only smirked and slipped his thumbs into Seokjin’s waistband, coaxing his hips up off the floor so he could slip the sweatpants down. He mouthed at Seokjin’s tented boxers, and Seokjin flushed a dark red, squirming to close his legs.   “Don’t be prude,” Jungkook said, pinching Seokjin’s thigh. Seokjin yelped. “I’ve got a hard on, you’ve got a hard on, surprise, we’re having sex.”   “You’re a baby. You’re not supposed to be saying those things!” Seokjin sighed, pushing the bangs that had fallen into Jungkook’s eyes. Jungkook only rolled his eyes at him and pressed his lips to the inside of Seokjin’s knee and then paused.   He scowled. “Holy shit.” He pressed his index finger into Seokjin’s knee and Seokjin tilted his head. “Does he leave marks everywhere?”   Seokjin laughed embarrassedly. “Well.. That one’s Hoseok.” Jungkook scowled and bit hard down onto the mark there. Seokjin just hit him on the back with his other knee, reaching forward to push him away. He said crossly, “If you can’t deal with all the marks on me, then you don’t have to.”   Jungkook grabbed him tighter. “Who said I can’t deal with it?” He smirked, grabbing Seokjin’s other knee and pulling it around his waist. He pressed his lips to the spot he’d just bitten and dabbed his tongue apologetically over the bite. He tucked his index fingers into the band of Seokjin’s boxers and tugged them off in one swipe.   His own clothes followed quickly afterward and Jungkook rolled them up to push under Seokjin along with the coats. “I don’t have lube,” Jungkook hummed, pressing their foreheads together. He pulled his hand up and pressed his fingers against Seokjin’s lips. It was so weird, being naked in the middle of the dance studio with Jungkook on top of him, but Seokjin decided to push the thought aside. He let his lips fall open and Jungkook pushed his index finger into Seokjin’s mouth.   Seokjin sucked, swirling his tongue around the digit and suckling earnestly. Jungkook was staring, he was aware, and he glanced up at him through hooded lids, letting his tongue dart out for a second. Jungkook cursed and he grabbed Seokjin’s chin and yanked him forward, shoving two more fingers into Seokjin’s lips. He was rough enough for Seokjin to almost choke, but Seokjin kept on, whining lightly.   Jungkook yanked his fingers out and pushed Seokjin’s legs wider apart, wrapping his lips around Seokjin’s cock without a warning. Seokjin yelped in surprise, knees sliding shut, but Jungkook squeezed his thighs and kept them open. “Wait, wait-“ He swallowed his words when Jungkook pushed a finger into him. His entire body tensed at the sudden intrusion and he gasped, gripping Jungkook’s shoulders. “Wait,” he called desperately, but Jungkook sucked hard enough for his hips to toss off the ground. He shoved his hands to his mouth, watching Jungkook with wide eyes. But but but he’s a baby oh god he’s underage and I don’t even-   Jungkook pulled his hands from his mouth. “I want to hear you.” He grinned, pulling his finger out and pushing back in two. He twisted, crooking his fingers upward and Seokjin let out a shaky moan. “And stop thinking the whole underage thing. I’ve fucked ladies twice your age.”   “Twice?” Seokjin demanded. “Really?!”   Jungkook shrugged. “No. Maybe like 30.” He grinned unashamedly. “That’s not that old, I guess. But don’t worry about it, hyung. I’ve been having sex since I was a freshman.” He pressed his lips against Seokjin’s knee. “I want to hear you. Don’t block your noises. I’m going to tie your hands if you do that again.”   Seokjin slapped his hands down onto Jungkook’s shoulders and gripped those hard instead when Jungkook bobbed his head back down, twisting his fingers back and forth and making Seokjin squirm. “Wait, I’m so close-“ He sobbed, and Jungkook shoved in three fingers, scraping his teeth lightly on the head and Seokjin threw his head back, stifling a scream with his hands.   He watched Jungkook swallow, grinning and licking his lips. “I told you,” Jungkook clicked his tongue, “that I was going to tie your wrists if you did that.”   Seokjin watched numbly as Jungkook expertly looped his shirt aroud his wrists, tying them tight enough so Seokjin couldn’t move them. “You’ve done this before.”   “Maybe,” Jungkook snickered. He ran his hands over Seokjin’s thighs. “I like this. The way your thighs are trembling after your orgasm. I like that a lot.” He pressed his lips to the milky skin of Seokjin’s inner thighs, hands resting lightly on the trembling limbs. Two of his fingers returned back to Seokjin’s ass, slipping inside the pucker lightly. “You’re so open. But still so tight. Who fucked you last night?”   “Jimin. It was this morning..” Seokjin swallowed thickly, watching Jungkook lazily finger him. He tried tugging on the shirt around his wrists. It didn’t give. He kind of liked it. Jungkook hummed and he added a third, smiling when Seokjin’s thighs trembled more violently under his hands. “Can you stand up? I want to fuck you standing up. We can lean on the mirror.”   Seokjin swallowed and twisted his waist to get Jungkook’s fingers out of him, but when he stood, Jungkook grabbed him by his waist and pushed his fingers back inside. “I’m trying to walk.”   “I know. You can still walk, can’t you?” Jungkook grinned, nibbling on Seokjin’s waist. “Come on, then.” He pushed Seokjin forward, making him take a step or risk falling. “I considered putting my dick in you and making you walk, but I decided to be nicer.”   Seokjin gritted his teeth against the moan that threated to push out of him as he walked, Jungkook’s fingers pushing in and out with every step. He took forever to get to the mirror and by then his cock was back hard and leaking. He all but collapsed onto the mirror, pressing his tied hands to the mirror. Jungkook bit down on his shoulder and barely gave him any respite before pulling his fingers out and pushing himself inside.   Seokjin let out a surprised cry at the stretch. It didn’t hurt – he was too prepped for that – but it caught him unaware. Jungkook hissed, gnawing at his earlobes. “Fuck, you’re so tight. No wonder everyone likes your ass so much. You were fucked this morning and just look at you. Eating up my dick like you’ve never had anything better.” Jungkook pushed Seokjin’s back, making him arch his ass up. He grinned at Seokjin through the mirror and pushed his legs wider open so he could have easier access. “Don’t block your mouth, hyung. Unless you want your hands tied behind your back.”   He set a brutal pace that had Seokjin reeling, screaming without even realizing he was. He clawed at the mirror for a handhold and one of Jungkook’s hands came up to thread through his fingers. Seokjin didn’t know how Jungkook was so good at this, and when Jungkook had even had the time to find his prostrate, but his knees were threatening to buckle. Jungkook kept him upright with one hand, biting hard down onto his shoulders and leaving red imprints everywhere. “Can I come inside?”   Seokjin nodded blindly. He reached down to grab his own cock, squeezing and pumping to match Jungkook’s thrusts inside him. Jungkook came first inside him, and Seokjin’s grip on the mirror slipped with his own orgasm. Jungkook fucked him lazily through his own spurts, pushing his own hands on top of Seokjin’s to catch the streams so it wouldn’t land on the mirror.   They fell down, Jungkook’s cock softening inside. Seokjin sighed and tried to twist away, but Jungkook stopped him with a grin. “Give me a minute, hyung. I’m young. I’ll be hard in a minute and I wanna fuck you on all fours.”   Seokjin wondered why he’d ever thought Jungkook was all innocent.     Please drop_by_the_archive_and_comment to let the author know if you enjoyed their work!
