Yang Jeongin x Male Reader
title credits to lovely anon.
warnings: brother's best friend, three years age gap if that's a thing, jeongin calls Mn "hyung" during sex, size kink kinda, choking, sex with clothes on, spit as lube (doesn't work but it does in fiction)
He's been obsessed with Mn ever since he was a kid. Mn was three years older than him and always came over to play with his brother. And even his brother's less closer friends were considered by Jeongin as his brothers, but not Mn. Oh absolutely not. That laugh, those hands, the way he would always bring him a candy or something when he came over?? The way he would help him with his homework and teach him better than his teacher did?? Jeongin used to debate in his head if he should run away and hide or go spend time with him. And as they grew older, the attraction grew too. And then he became and idol, and Mn moved to France for university.
Right now, Jeongin was home. Finally on a well-needed break from idol life as he lazed on the couch, eating chips and binging shows. He heard the doorbell ring, but he was one with the couch now, ain't no way he's getting up.
"Eomma!!," he called, hoping his Mom would answer the door. He could hear his mom tsk affectionately as she made her way over to the door and opened it.
He couldn't see who was at the door, but his mother's excitement and the way his brother bolted down the stairs made the butterflies in his stomach return. Was it Mn? He slowly got up and went towards the door, carefully for some reason, as if approaching a snake. He almost choked on his chip when he saw who was at the door. Mn. Mn, whose cuteness was still there despite him losing his baby cheeks. Mn who looked like a damn model. He grew up. A lot. Seeing Mn's sculpted body, and his mature face which still had the boyish charm made the butterflies in Jeongin's stomach turn into birds which clawed at his stomach. In a good way, of course.
He watched as his brother tackled Mn in a hug, and Mn returned it. He could only watch as Mn's forearms rested on his best friend's back, flexing due to the strength of that hug. He gulped, smiling awkwardly when he saw Mn's eyes on him.
"H-Hi hyung," Jeongin smiled, a laugh coming out when Mn hugged him as well.
Jeongin, his brother, and Mn were watching a movie. Everyone else was asleep. He could hear Mn's laughs at the movie. He wanted to smile and admire how pretty the older man's laugh is, but his mind just had one image: Mn's forearms. God. Not just his forearms, but him in general. He loved how big Mn was. How he was always bigger than him. He tried keeping his thoughts pg, but his mind was just not letting him. He put a pillow in his lap to hide his erection, but the ever so observant Mn noticed. He smirked and put an arm around Jeongin's shoulder, feeling how the younger tensed under his touch.
As the movie ended, Jeongin's brother went to the kitchen to see if they have snacks, knowing damn well they don't. He sighed and went back to the living room.
"We have no snacks. I'm gonna go get some, wanna come with me Mnie?"
Now, Mn knew how much time his best friend would take at the convenience store. He knew he'd get carried away, he'd walk around, get tired, and then end up eating ramen or something at the convenience store, then resume his shopping, and then walk home. He had plenty of time. Once his best friend left, Mn turned to Jeongin.
"What's with the pillow, hm?"
Jeongin was too enamored with Mn's forearms to notice that accent before. His cheeks tinted pink, he spoke, "Nothing."
"I know it's not nothing, innie. Don't worry, love, it happens to all of us."
His tone made Jeongin want to pounce on him, and so he did. He crashed his lips to the older's, relishing the taste of his chocolate chapstick. Mn smirked against his lips, hands moving to rest on Jeongin's waist. He nipped at his bottom lip, sliding his tongue in as the younger let out a moan at the soft bite. He could feel Jeongin's hands up his shirt, exploring the muscles underneath. Mn broke the kiss to catch his breath, but dove right in once he saw Jeongin's hands slip down his sweatpants. He let out a low moan once Jeongin started stroking his dick.
"Need you, hyung. Please."
"Aw, look at you. So cute."
Mn's spat on his fingers and slid them in one by one into Jeongin's hole, peppering kisses down his neck, making the younger moan more. He moved his fingers in a scissoring motion, and Jeongin grabbed his hand and led it to his throat, making Mn smirk as he wrapped it around his neck.
"You like that, baby? God, you look so good right now. Makes hyung wanna devour you."
"Please do, hyung…please.."
Mn had to control himself when he saw the slight pout on the younger's lips. He pressed a soft kiss to it before pulling out his fingers and spreading Jeongin's legs with that hand. He slowly slid himself in, watching as his mouth gaped open, gasping at the intrusion. He started moving once he bottomed out, hips snapping against him at a pace which made the other male moan so loud. He put a hand over Jeongin's mouth to muffle his moans.
"As much as I want to hear your pretty sounds, baby, you gotta stay quiet, yeah? Don't want your family to hear now, do you?"
Jeongin shook his head frantically, eyes rolling back as Mn's thrusts grew stronger. He hooked Jeongin's leg over his shoulder to go deeper and moaned as the younger clawed at his back. He captured his lips in yet another kiss, tongue exploring his mouth as he quickened his pace, the searing kiss swallowing both their moans.
Jeongin threw his head back as he came, soft whimpers leaving his pretty lips. Mn pulled out and jerked himself off. He pulled up his pants and went to the kitchen to grab paper towels to wipe everything off after washing his hands. He cleaned Jeongin up who quickly put his pants on when he heard footsteps. Mn settled himself casually on the couch, wrapping an arm around Jeongin's shoulder, looking up when he saw his best friend.
"Finally. What did you eat at the store today?", he asked, as if he wasn't just fucking the man's brother minutes ago.
