Work Text:
Yoongi isn't much of a gym rat himself—he hasn't visited a gym in six years or exercised at all aside from going on a leisure walk through the park in five—so he can't really know what exactly it is about going to the gym that gets Namjoon all worked up, but to be fair, he hasn't tried all that hard to figure it out in the first place.
Namjoon goes to the gym nearly every day and comes home every single day, without fail, desperate beyond belief to get some release.
(Little does Yoongi know, it's because Namjoon spends the whole time at the gym thinking of him. A few years ago when Namjoon first got into working out, he thought of Yoongi as a way to distract himself from his brutal exercises so that he could push through them and the time could go by quicker. Nowadays, Namjoon was in great shape, and working out wasn't as hard for him as it used to be, but he still thought of Yoongi the whole time he was working out, and it never failed, his thoughts would always turn from PG to rated R within mere minutes.)
He always ends up fumbling with the keys right outside the front door for a good minute before finally managing to unlock it, and then in he runs, sweaty and breathless since he refuses to use the showers at the gym—he had a long list of reasons for why he refused to, and first on that list was the fact that home was only a five-minute drive away so he might as well shower at his own place—he looks around frantically until he spots Yoongi, and once he does, he storms over to the man and lifts him up onto the nearest surface, staring at him with pleading eyes until the older man scoffs and sends him a curt nod.
After which, Namjoon will hurriedly maneuver both their pants and underwear down, stroke his cock a few times, and then push it between the soft meat of Yoongi's thighs.
It's become a routine for them by now.
A few years back, when Namjoon would come home desperate to get off, Yoongi would usually respond in one of three ways; Laugh at the man until he turned into a whining mess, pleading with Yoongi to help him out, in which case, Yoongi would finally agree and they'd make their way to the bedroom (or the couch if Namjoon couldn't wait that long) to have sex. Drop to his knees to give the man a quick blowjob if he didn't feel like having sex at the moment. Or he'd simply offer a handjob if he didn't feel like doing either of those things. Namjoon would not care either way, always happy to take what he could get.
But there was a turning point after a while. Namjoon had come home desperate to cum as per usual, and Yoongi had been in a bad mood that day. Yoongi didn't want to take his own bad mood out on Namjoon, so he'd simply huffed and guided Namjoon to the bedroom, stripping down and laying on his back with his knees held up, his hands resting beneath them for support.
"Go ahead, get off. And make it quick!" He'd huffed, rolling his eyes and glaring up at the ceiling. "I don't feel like getting fucked. Just get yourself off and cum inside me."
Namjoon's interest had immediately been piqued. Something about having Yoongi acting so disinterested and annoyed at the inconvenience that Namjoon was causing him was so...Hot.
Needless to say, after that day, they began to explore Namjoon's newfound kink a little bit more.
And now here they were, with Yoongi sitting on the kitchen table, Namjoon between his legs panting loudly as he fucked Yoongi's thighs quickly. His hips pistoned back and forth with all the speed of an eager bunny humping something, and Yoongi clung to the man's shoulders to keep himself from being moved around too much due to the force of Namjoon's movements.
Yoongi's face was completely blank, and he blinked owlishly at Namjoon every time the man looked up from his thighs and into his eyes. Namjoon would groan every time he looked at the man's bemused facial expression, then rested his forehead against the man's shoulder for a few moments, warm breath hitting beautiful, pale skin as he did.
Yoongi would take the few moments that Namjoon wasn't focusing on his face to allow his eyes to roll into the back of his head, his mouth falling open slightly as he let out silent moans.
It shouldn't be so pleasurable to have Namjoon's cock sliding between his thighs. Really—There was no stimulation for his own cock or his prostate, so it shouldn't make him feel as if he was on the brink of having an orgasm himself, but it did.
It felt so fucking good, and Yoongi just wasn't sure why.
Maybe it was simply because he enjoyed being used by his boyfriend. Knowing that he could get Namjoon off even without having to use his mouth, hands, or ass. He could simply allow the man to rub his cock against his smooth skin—or between his thighs—and just that would be enough to make him cum. Yoongi felt a little powerful knowing that, but more importantly, he felt useful. His body could be used to get his boyfriend off in so many different ways. He could please his boyfriend in so many different ways. God, it felt good to know that.
Maybe he just liked how needy and desperate Namjoon was for him. How much the man wanted him. Knowing that he drove the man crazy. There had been so many times when Namjoon had begged—on his knees, tears in his eyes, bottom lip wobbling and everything—Begged Yoongi to help him. 'Please, Yoongi, please—help me cum. Make me cum. Let me cum, baby, please!' And he would do anything, say anything, to get the man to agree, desperation turning into relief once Yoongi finally gave him the go-ahead. Yoongi enjoyed watching the man grovel. Namjoon wasn't the type to beg outside of the bedroom, but fuck, if he wasn't more than willing to plead with Yoongi when he wanted to cum badly enough, and Yoongi adored that.
Maybe it was because Namjoon looked so fucking good like this. Sweat dripping off his forehead when he pulled away from Yoongi's shoulder. Sweat making his entire body glisten, actually, and running down between the lines of his abs. His brows furrowed, a concentrated frown on his face as his eyes were squeezed shut tightly, his lips pursed as he let out quiet groans of pleasure every now and then. His cock glistening with precum, making a sloppy, wet sound every time he moved his hips back and forth.
Shit.
Yoongi wasn't sure what it was, all he knew was that he was just as close to coming as Namjoon was—which made his cheeks flush bright pink as embarrassment coursed through his entire body, and the embarrassment only added to his pleasure.
Sometimes, Namjoon would grab his neck tightly and stare him dead in the eyes, dimple poking out as he let out a low, breathless chuckle.
"Such a fucking slut. You love being used like some little fuck toy, don't you? Gonna cum untouched just from me fucking your pretty thighs? How fucking pathetic..."
Sometimes the man would give his cheeks a few slaps and drag him in for a heated kiss as well, and that—Well, that would seal the deal for sure. Yoongi wouldn't be able to keep himself from spilling all over his stomach even if he tried.
Today wasn't one of those days, though. Yoongi was determined to keep himself together long enough for Namjoon to cum before him. On days when he wanted to hear those degrading words and receive the rough treatment from Namjoon, he would give the man a signal, but today, no signal came.
Instead, Yoongi sat there chuckling lowly as Namjoon let out a high-pitched 'Ah!', mouth falling open as he pulled his cock off from between Yoongi's thighs and spilled his seed all over them.
Yoongi watched with a blank expression as the man's cum landed all over his thighs, and while he would occasionally offer some assistance by reaching out to stroke Namjoon's cock as well, he didn't this time. He simply watched as the man stroked himself vigorously until every last drop had landed on Yoongi's skin. And then, Yoongi ran a finger through the mess that Namjoon had made on him and held it up to Namjoon's lips, letting out a pleased hum as the man eagerly welcomed it into his mouth.
Namjoon wrapped his lips around the finger and whined as it was almost immediately pulled away from him.
"On your knees," Yoongi ordered him, reaching up to push on his head until the man dropped down to his knees as told. "Clean me up, pup."
Namjoon didn't waste a second, immediately doing as told, tongue darting out to lick up all the cum that he had just deposited on Yoongi's pretty skin. He cleaned the boy's thighs thoroughly, not a drop of cum left on them, but he continued to lick and suck on the skin even after it was clean, occasionally biting down on the soft flesh to leave a few marks.
"Make me cum." Yoongi told him after leaning back and spreading his legs a little.
Namjoon moaned quietly, already pushing one of Yoongi's legs up and lapping at his hole before he could even get the words out, but Yoongi quickly stopped him with a sharp tug on his hair.
"No, I wanna see those pretty lips of yours wrapped around my cock. Suck me off, and do a good job so I can cum down your throat."
Namjoon felt lightheaded when Yoongi spoke to him like that. Like he could just topple over right on the spot, overwhelmed by how damn sexy his boyfriend was.
He wrapped his lips around Yoongi's length, opening his mouth as wide as he could and pushing himself down until his nose rested against the older man's stomach. He licked at the underside of Yoongi's cock, as his mouth slid back up, then down again, until he had found a steady rhythm. He made sure to suck on the tip of the man's cock every time he came up too, and Yoongi's breath hitched every time.
The older man's head fell back, teary eyes focused on the ceiling as his body quivered. He wanted to last longer—Only for the sake of keeping Namjoon's mouth wrapped around his cock—but as he listened to the wet sound of Namjoon sucking him off, the man's drool coating his cock and dripping down his balls, he knew that he wouldn't be able to last much longer.
Namjoon knew it too when Yoongi's fingers curled up, gripping his hair tightly as the man held his head down to keep him from coming up again.
Namjoon moaned a few times, knowing that it'd send Yoongi over the edge, and he wasn't shocked when the man's cum began spurting into his mouth just a few seconds later, hitting the back of his throat. Namjoon swallowed as much of it as he could—with much difficulty, considering the fact that it was a little difficult to swallow with a dick shoved halfway down his throat—but some still leaked out of the sides of his mouth along with his spit.
As he coughed and spluttered, staring up at Yoongi with a red face and tear-filled eyes, clearly struggling to breathe, Yoongi gave his cheek a few soft pats.
"Good boy. Good fucking boy...Shit. Your mouth is so good, Joon, and look how pretty you are. Look how pretty I made you."
Yoongi pushed at the man's shoulders until Namjoon pulled his mouth off of his cock, and Yoongi watched as spit and cum leaked out of the man's mouth, coating his lips and dripping down his chin.
Yoongi ruffled his hair, running his fingers through it a few times, chuckling breathlessly as Namjoon's eyes fluttered shut as he enjoyed the petting.
"Good little puppy," Yoongi smirked. "Now, why don't you go to our room and present yourself for me? Or would you rather I bend over and let you fuck your cum inside me until I can't physically hold anymore?"
Namjoon whimpered, looking a little distraught as he was tasked with the job of having to decide which one he preferred. He stared up at Yoongi with pleading eyes until the man shook his head and laughed.
"Dumb little pup can't decide anything for himself, huh? I don't feel like giving you instructions on how to fuck me properly today, so you just go get on the bed and be prepared to lay there like the useless little fuck meat that you are and I'll do all the work, okay?"
"God, yes!" Namjoon moaned before standing up to run off—only to be stopped by the leg that Yoongi stuck out. The older man sent him an unamused look and Namjoon thought for a few moments before gasping and dipping down to his knees again in order to crawl instead.
Yoongi smiled. "Good boy."
