34 + 35

Ariana's words blared loudly in your ear as you entered the fitness center looking for your gym rat of a boyfriend. Recently, he'd picked up his workout schedule more than before, resulting in the bigger and better namtiddies you so enjoyed along with buffer everything else. You weren't complaining at all, especially since his new bodybuilding addiction had led to him showing off his higher stamina in bed, insisting on round after round just because he could. Yeah, you were perfectly fine with that.

You found him over by the weights station, sitting on the bench facing the mirror as he worked on his biceps. He was the only one still here, the late hour of the night being his preference for hitting the gym as he enjoyed the peaceful quiet. His face contorted at the effort as he grunted with every lift, sweat dripping on his forehead, his hair wet, body glistening with the exertion.

You didn't want to interrupt, loving seeing him like this. You would've taken out your phone to record a video for your own private archives, just to store away, if he hadn't looked up and caught your eyes in the mirror. His lips curved up into a smile at your expression, dazed with your head tilted, eying him hungrily. "You came for the free show?" He chuckled.

You giggled as you walked over, putting one knee on the bench behind him as you leaned over, embracing his body and feeling his taut muscles under you. "It's not fair, you're too distracting."

"Look who's talking," he snorted, reaching around to pull you into his lap after setting the weight down. "You just walk in and I loose count of how many sets I've done."

"You've two more to go," his trainer's voice suddenly sounded from behind him, returning from putting the other equipment away. Namjoon nodded obediently and picked up the weight again, gesturing for you to get off so he could finish, but you didn't budge. "Can't I stay? I won't impact your training," you pouted. You knew Namjoon could never say no to you. Which is why he sighed defeatedly, a small smile on his lips as he shook his head before looking to his trainor for approval. Once he got the okay, he secured on arm around your waist and the other gripped the weight. You were pressed against his chest closely as he started his second-to-last set.

His trainor counted each one with him, commenting words of encouragement to keep him going. But you could barely hear any of that, only background noise compared to Namjoon's grunting in your ear. His hot breath was on your neck with each exhale, and you could feel his body heating up from the excersise.

The music was the only other thing you could hear aside from Namjoon’s pants, but that's probably because you had a one-track mind at this point, the lyrics capturing exactly what you were thinking.

Baby you might need a seatbelt when I ride it

Imma leave it open like a door come inside it

Even though I'm wifey you could hit it like a side chick, don't need no side dick

You couldn't help the heat that flooded to your core at the sound of your boyfriend's exerted grunts in your ear, paired with his arm clutching you tightly around him, making you feel every flex of his muscles. And not to mention, you were sitting on those God-crafted thighs that had your mouth watering before you even thought about his dick. You tried to be subtle about the way you moved in his lap, trying to relieve some tension and the fire on your skin, and get comfortable without disturbing him. He may have not noticed at first, too enraptured in his gains to pay attention to anything else around him, but his dick took full notice. Enough of your wiggling his lap causing his gym shorts growing tighter and tighter around his crotch.

His arm pulled you impossibly close, leveling his mouth with your ear to growl, "What are you playing at, babygirl?"

You shivered at his deep voice, feeling the rich timbre in his chest. "What are you talking about, Daddy?" you whispered, moving again in his lap to brush against his semi-hard cock through his shorts. He let out a low groan at your movement, gripping your waist to keep you still. "I have one more set left. Be a good girl, or you're going to get punished. Understand?" He grunted lowly. You bit your lip, his tone sending another rush of heat to your core, your arousal pooling in your panties.

He switched the weight in his hands, his trainor starting his count again, oblivious to what was going on between you. Namjoon had told you to behave, to be a good girl. But how could you when he was basically making sex noises in your ear and flexing his muscles with you in his lap with a front row seat. Short answer: you couldn't.

You wrapped one arm around his neck, playing with the hair at the nape of his neck as you leaned in to his ear. "Why do you listen to 34 +35 when you work out, Joonie? Is it because you wanna fuck me till the daylight?" You felt him stutter in his set, almost dropping the weight, but quickly regaining his composure. He lowly uttered your name in warning, but you didn't heed it. "Is it because you wanna keep me up? Or so you can prove you can keep it up?" You gestured down to his shorts at the tent forming, becoming more obvious by the second. "Does it motivate you to get all big and strong and make the bed shake so hard the neighbors think there's an earthquake?"

"Yn," he muttered under his breath, his teeth gritted. You could feel his self-control draining as his focus fell to you rather than his workout. And you didn't mean to do it, honestly that wasn't your intention at all when you had walked into the gym. But workout Joon was irresistible, what were you supposed to do? Not rile him up in hopes he would use you as his workout instead?? That's crazy talk.

"C'mon baby," you continued, dragging your nails across his the back of his neck, "Finish your set so you can show me who I belong to." Your sentence ended with a slight whine in your voice as your own desperation showed itself. That gave him his last burst of concentration, just enough to finish the last 10 in his set before he was dropping the weight with a loud clang to the ground and lifting you up, hands on the back of your thighs. He murmured a quick thank you with a small bow to the trainor before he was practically running out of the fitness center and into the elevator that went straight up to the apartment.

"You're seriously such a brat." He growled, voice muffled as his mouth attached to your neck. You whined out his name at how he was marking you, a taste of what was to come later. "Can't be without my cock for one fucking second."

One hand hand was kneading your ass and the other held you up as he slammed you against the elevator wall. His mouth moved from your neck to your mouth, kissing you heatedly. You let out a moan as he pushed his tongue into your mouth, your lips opening submissively for him.

Your frenzied makeout session was interrupted by the ding of the elevator, signaling you had reached your destination. He readjusted you in his arms as he exited and headed for the door. His lips found yours again as he walked the well-known path that was ingrained into his muscle memory. He only stopped to come up for air when he reached the door, pressing you against it while fiddling with the lock.

"Joon," you whined as the rattle of the keys continued while he tried to find the right one. "I'm trying baby, but—" his clumsiness jumped out. You huffed in his ear, throwing a mini fit at not getting what you wanted fast enough. But he was quick to put you in your place, rolling his hips against yours, making you feel his rock hard cock.

"Baby's throwing a fit, huh? You think you're cute?" Unfortunately for him, he did think you were cute. Especially when you got all whiny for his dick. It made the his cock stand right up when you pouted at him with those pretty lips and eyes. He could never deny you when you had that look, and honestly, he never really wanted to deny you.

Finally, after what felt like forever, he got the door open, pushing you both inside. He was barely able to set you down on your feet before pulling off his shirt, his chest muscles greeting you, dripping with sweat from his workout. You reached out unconsciously for his tiddies, running your hand down his body in a trance. He chuckled at your awe, and let you have a moment before he was tugging at your shirt and shorts.

"You worked hard, Joon." You panted as he towered over you, walking you backwards to the couch. "Think you got any of that left for me?" You fluttered your eyelashes for good measure to get what you wanted. Namjoon bit his lip at your insinuation, pushing you down onto the couch before hovering over you, chest heaving like the beast he was.

"Careful what you ask for, sweetheart."

Your mouth broke into a cheshire cat grin, playful eyes with a hint of determination. You wanted it all, every inch of this man standing above you right now. You pulled him down to meet your lips, reveling in the feeling of his tongue in your mouth.

He flipped you both over, instead having a seat on the couch and pulling you on top of him. "You wanted to ride my thigh so badly couldn't even wait till we got home, huh?" His voice was muffled in your neck as his hands found your hips, gripping tightly and positioning you. "Well? Show me what got you so riled up, sweetheart." He flexed his thigh under you, and you could feel it in between your legs, your arousal flooding your core. You let out a moan as you lost all sense of your surroundings and moved your hips back and forth on his muscular thighs. Your hands came up to steady themselves on his shoulders, and he leaned back, hands propped up behind his head as he watched you, a cocky smirk on his face.

"Damn, babygirl. I can already feel you soaking through your panties." He was right; your arousal was quick to make an easy slick for you on his thighs, causing you to rut frantically against him in search of stimulation to your clit. You rode his thigh like a pony, your whines and whimpers cutting through the air in symphony with the squelch of your skin. It was filthy, the way you were so desperately grinding yourself down, knot tightening your stomach.

You fell forward, losing your grip on his shoulders, as you caught yourself on his lap. Loud whimpers of his name left your lips as you chased your high, his thigh deliciously rubbing against your folds. You were breathing heavily, sweat beading on your forehead, mouth falling open. Your eyes rolled back as you found your rhythm. Your stomach tightened in anticipation, your orgasm fast-approaching.

He tilted your head up to look him in his eyes, intensely gazing down at you. You felt so dominated in the moment and he hadn't even done a thing. You could just feel your body tingle in anticipation for what you wanted him to do to you, how much you wanted him to stuff you full with his cock—

"Stop." His voice commanded. And if you hadn't been looking at him right that moment, you would've missed it for being so lost in your own pleasure. Loud whines left your throat as you begrudgingly slowed your movements. He smiled at your state—eyes wide, hair messy, lips pouty, overall fucked out. So cute.

"You were a bad girl, baby. You don't get to come yet," he reprimanded you. His tone was soft, but his words made you slump into his embrace, silently begging, big eyes watery from your robbed orgasm. "Nope. That's not gonna work this time," he tsked, but he still had to look away from your face lest he give in. "Lay down on your stomach, ass up."

You obeyed, not wanting to warrant any more punishment than you already had, but not without a bratty pout. You lay yourself across his lap, face in the throw pillow closest to you. You knew what he meant, stroking your ass cheeks so sweetly before landing a hard slap, making you yelp out at the loud smack. "Count," he ordered. You nodded meekly and whimpered out number after number as he spanked you until your ass was bruised with his handprint, relishing in his gruff voice whispering dirty things to you. You were sufficiently wet, to say the least, at this point to take his giant cock without any prep, and you hoped he would give it to you soon. You'd been aching for its stretch ever since you first felt it press against you while you were in his lap.

"Joon—please—," you begged. He tutted and landed another slap to your reddening ass. "That's not my name, sweetheart."

"Daddy, please—," you cried out, tears welling up in your eyes, "Please fuck me—"

Namjoon looked at you in your pitiful state. You looked so desperate, pushing your ass up further into his hand. sounded so desperate to be fucked, whiny moans leaving your pretty lips. Ready to take any punishment he gave you if it meant you'd get his cock. Poor baby, he thought as he rubbed your ass soothingly, you just wanted to be fucked by daddy. He flipped you over on your back, scissoring you open as he moved to hover above, and fucked is what you were going to get.

"Sweetheart, you're already so wet," Namjoon groaned, easily sliding three fingers into your cunt. He watched his fingers thrust into you hungrily, the sight making him painfully hard in his shorts. "Just from riding my thigh? Or, does my baby like getting punished, huh? You like it when I spank you silly? Is that why you were being so bratty?" You let out a high-pitched moan at his words, bucking your hips up. You were already so worked up, and his fingers felt so good inside you you were on the edge. And he was right—him spanking you had sent arousal right to your core, and you would be embarassed, but your pride was at his feet and you couldn't give less of a fuck.

Namjoon seemed to sense how close you were with your walls clenching around his fingers and decided you were ready. He pulled his shorts and underwear off, presenting you with his hard cock, red angry tip leaking with precum. He gave himself a few strokes before lining up with your entrance and pushing in.

"Ah fuck—," he grunted in your ear as you moaned at the stretch. He slid in easily, the stretch feeling so damn good. He had to pace himself, remember not to go fucking ham right away, but it was hard because your pussy felt heavenly around him, welcomingly clenching your walls around him. "Yn, baby—," He slowly pulled out and rammed back in, causing you to wrap your arms around his broad back and sink your nails in at the sudden roughness. He continued to thrust into you hard, pulling frantic moans and whimpers of his name from.

Your silk walls felt so good around him he couldn't contain himself, setting a brutal pace. You weren't much better off, clawing at his back, moving your hips up to try and meet his. He leaned over you so closely you could see the sweat glistening off his chest, his freshly worked-out biceps bulging next you as he held himself. You took a moment to appreciate post-workout Joon in all his daunting muscle glory—if he kept going at this rate, he'd be too big to fit in a damn car.

He was rutting into you so hard, putting those muscles to good use, pushing your legs up into positions that made you feel like you were working out. You vaguely made out the sound of the couch scratching against the wood floors as it shook, the coffee table next to you slightly trembling from the tremors as Joon fucked you like he paid for it. It was barely in your realm of consiousness, though, for how fast Joon's fingers were moving against your clit.

"I can feel how tightly your squeezing, baby. You're close, aren't you?" You whimpered a small 'yes' followed by a nod of your head. He chuckled at your response, "My desperate baby. Should I let you come now? Do you think you deserve it?"

You moaned out and bobbed your head quickly, trying to push up against him as you felt your orgasm nearing. He buried his face in your neck, tugging at your earlobe before growling, "Cum for me, yn."

"Fuck—Joon!" The tension in your center broke as your climax washed over you, coating his cock in your arousal. He thrust into your cunt, squelching sounds loud with the new slick you provided, mixing with your moans of pleasure as he let you ride out your high. "Good girl, yn. Cream my cock just like that," he praised, and you revelled in it, giving him everything you had.

Once you had come down from your high, he pulled out and lied back on the other end of the couch. "Cmere, baby." He beckoned. You crawled over on top of him and he pecked your lips before rearranging you both, sitting you on his face as you were now confronted with his engorged cock. You didn't hesitate to put your mouth on it immediately, trying to take in as much as you could at once. You were a bit too ambitious, choking on his huge length, before going back in at a more steady pace, using your hand to pump what you couldn’t fit in your mouth. He was at work behind you, licking you clean of your arousal, tongue lapping at your folds, trying to taste every last drop.

You took him deeper and deeper with every bob of your mouth. It wasn't long before he was groaning behind you, muttering curses under his breath while stroking your ass cheeks. "Keep doing that thing with your tongue, baby. I'm almost there," he grunted. You were spurred on by his words, now warmed up enough to try to take him all the way. You pushed your head down as far as you could, nose centimeters from his base. Namjoon let out a loud Fuck as he jolted his hips upwards, hitting the back of your throat roughly. Tears welled up in your eyes but you kept your mouth on his cock, letting him fuck up into you. He was spilling his seed inside your mouth with a moan of your name. It leaked out of your mouth, and you were taking shorter breaths, but you worked him through his orgasm like a good girl. He praised you after, stroking your gently as you pulled your mouth off his cock.

He moved you around to lay your head on top of his chest, your breaths in sync. You found his namtiddies incredibly cushioning, reaching up to squeeze one with your free hand. He chuckled at your action, kissing your forehead.

"You gave Ariana a run for her money," you mumbled against his chest. He eyes crinkled with his proud smile, pride welling up in his chest. You were a testament to your statement yourself, completely tuckered out from him fucking you, eyes heavy as your muscles finally relaxed.

"But we didn't go all night baby," he teased, strong arm pulling the throw off the back of the couch and settling it over you.

"Mm, next time." You promised, drifting off to sleep. Namjoon let out a small laugh at your determination, knowing next time, you'd have to pump yourself full of coffee before you'd have energy to stay up all night long. He was looking forward to it, though. And, yeah, you were right. He did listen to 34 + 35 purely because he would think of you, and it motivated him to get bulk up so he could fuck you whichever way you wanted it. And what about it?
