Chapter Text
It all started when Kyungsoo decided to treat himself after working out at the gym. It had been a hot day, and he’d been adhering pretty strictly to his clean eating regimen, so he felt okay about *one* indulgence. The cooler outside of a convenience store was packed with tantalizing ice and glass bottles that he initially thought might be a foreign beer brand. As he approached though, he noticed the little hand-drawn sign stuck in with the bottles, little effervescent bubbles doodled around the edges:
Cream Soda - Sparkling drink,
Silky smooth cream,
Yum, yum, tasty!
He didn’t think twice, snagging two bottles and heading straight into the store to pay for it. He left the store, cap pulled low over his eyes with both bottles hanging from his right hand. They made a light clinking sound that was almost musical as he walked home.
Kyungsoo tossed his cap in the front closet along with his shoes and called out, “Anyone home?”
“I’m in the office, hyung,” Jongin’s voice floated from the back of the apartment.
Kyungsoo made his way over, leaving one bottle on the kitchen counter as he passed through. He paused in the doorway of the office, leaning against the frame and taking in the sight of morning Jongin.
Jongin is at the computer, typing away on his mechanical keyboard. Shirtless. Tan skin glowing. Slept-on-hair in disarray, sticking up at odd angles and begging for a hand to get in it. He has on thin flannel pants that sit low on his hips because the waistband has all but worn out with the years of use.
Kyungsoo wants him.
Some days after working out, he’s just wiped and needs to laze around awhile before he can do anything else. Others, like today, his testosterone and endorphins are raging post-weight lifting.
So he decides to bait his roommate.
“Whatcha up to?” he asks in a bit of sing-song tone he hopes is alluring. Jongin has told him he likes his voice before, so he plays it up at useful moments like this.
Jongin keeps typing away, rapidfire. “Just answering a work email. Woke up a bit later than I intended,” he says sheepishly, with a halfway embarrassed smile that he shoots at Kyungsoo, eyes finally flicking over to him in the doorway.
Kyungsoo makes a show of twisting open the bottle top, forearms flexing and popping the cap off with a satisfyingly crisp noise. He has Jongin’s attention now.
“What’s that?”
“Cream soda,” Kyungsoo croons before taking a slow and suggestive swig of it. He tilts his head back as he brings the bottle to his plush lips, letting his eyes droop half mast as he gulps some of the creamy liquid down. He can feel his Adam’s apple bob a bit exaggeratedly as the delicious soda goes down. In an effort to glisten his lips with some of the liquid, Kyungsoo accidentally drips some out the side of his mouth. He feels it glide down over his neck as he slowly stops drinking. “Want some?” he asks in a low voice.
“Yes.” Jongin is out of his chair and in front of him in just a few heartbeats, dark pupils fixated on Kyungsoo’s neck.
Kyungsoo tilts the bottle toward him, offering a sip. “Or there’s more in the kitchen if you’d rathe--” His words are cut off by Jongin moving his hand with the soda aside. Jongin wraps a warm palm around the back of Kyungsoo’s neck and licks the trail of cream soda off of his throat, following the path all the way up to his moist lips and tonguing inside for a wet kiss.
Jongin kisses like he wants to consume, and Kyungsoo is a-okay with that, giving him the reins to meld their mouths as he likes. The kiss is needy, maybe even needier than Kyungsoo was feeling when he decided to provoke him like this. Jongin’s mouth feels amazing on his, passionate but not rough, making him feel desired. Kyungsoo can’t help the small smile that forms on his lips as Jongin keeps kissing him before hesitating like maybe he should stop… and then kissing him again.
When Jongin does pull back, he’s searching Kyungsoo’s eyes, asking questions without words. Kyungsoo gives chase, grabbing at Jongin’s waist to bring him closer again as he sucks onto his lower lip. Jongin easily magnets back to him, pressing in from head to toe and crushing Kyungsoo against the doorframe.
Kyungsoo’s hands gain a mind of their own as they slide over Jongin’s bare lower back, enjoying the smooth skin under his roughed up hands, small callouses from the bench press bar still present from this morning. The soda bottle is still looped between two fingers on his right hand, and it glides over Jongin’s ass and settles in his crease as Kyungsoo’s hands roam. Kyungsoo makes a point of applying a little pressure with the bottle to make clear his intentions today are more than just kissing, and it gets a gasp out of him, breaking their heated kiss. Jongin’s mouth works its way back down Kyungsoo’s neck, lapping over the previous path of the cream soda.
“You taste incredible,” he murmurs against the hollow of his neck and shoulder.
“Probably just the soda,” Kyungsoo mumbles, taking another big gulp to refresh his mouth. If Jongin likes it, he wants to taste as much like cream soda as he can. He puts a finger under Jongin’s chin to raise him back up for a wet liplock and lets him taste it on his tongue.
“Mmm,” Jongin moans in approval. “It’s definitely more than the drink - it’s you, too, hyung.” He pulls the thin white t-shirt off of Kyungsoo and spots the damp line of soda that snaked its way under his shirt and between his pecs. Jongin zeroes in on it, immediately laving a stripe up his chest.
Kyungsoo lets out an involuntary groan and its echo through the room and hallway reminds him they should probably close the door, lest any of their other roommates find them and ask questions neither can really answer. He slides them out of the doorway and against the wall instead, shutting the door and pressing in the lock button with a soft click.
The noise gives all the permission Jongin needs to hear that they’re doing this. Not like it’s the first time, but they’re not exactly ‘together’. They’ve gone through spells of hooking up regularly and then droughts of no action for weeks or even months at a time. They’ve never talked about it, so Kyungsoo’s not sure if Jongin just gets busy or bored or what, but it hardly matters right now because Jongin is yanking his sweatpants down.
“Do you work out with this just swinging everywhere?” Jongin asks as he takes Kyungsoo’s bare dick in his hand, no underwear in sight. “That hardly seems safe. Or fair to any other gym goers who need to concentrate.”
“I showered and changed after,” Kyungsoo explains, feeling his concentration focus singularly onto Jongin’s hand wrapped around him. He’s so hard already, and it’s been awhile since his last masturbation session, so he might not last as long as usual. “Fuck.” He curses in pleasure and bangs his head back against the wall. He takes another gulp of soda to quiet himself. Jongin is caressing his cock in long, unhurried strokes, with his mouth exploring across Kyungsoo’s chest, the point of his tongue tracing every edge of muscle it finds, gliding along the underside of his right pec, across his upper abs, and back along his left tit.
It’s not like Kyungsoo is ripped or anything; he’s just been diligent and serious about getting in shape the past several months, and the consistency has paid off in some toned definition throughout his body. Definition that Jongin is apparently appreciating a lot. “Your body looks so great these days, hyung.” His warm breath skates over Kyungsoo’s left nipple, causing him to tense and flex virtually every muscle in response. His cock jolts, and Jongin heads lower.
Kyungsoo runs his fingers through Jongin’s honey-colored hair as he kneels in front of him, intentions clear. He takes a swig from Kyungsoo’s soda bottle first, smacking his lips after and giving a little head nod. “The best flavor has to include you,” he proclaims and slowly sinks down on Kyungsoo’s dick, bobbing once, twice, and then swirling his tongue around the tip to lap up the precome that leaks out.
Kyungsoo feels his whole body surge, fingers fisting in Jongin’s hair as he revels in the soft, wet heat of his mouth. “Sorry,” he manages to mumble before thumbing over Jongin’s cheek and settling his hand on his nape instead, fingers contracting around the back of Jongin’s neck. He hopes this way it’ll feel more like a neck massage if his grip keeps tightening in reaction to the racing pleasure he’s feeling.
Jongin skates his hands up the back of Kyungsoo’s legs, over the cut of muscle above his hip bones, and down the fronts of his thighs. This sensual petting alone would be priming Kyungsoo for release, even if his mouth was just holding still. But no, Jongin is now tonguing and sucking for all he’s worth on Kyungsoo’s cock. His lips are smooth, like he woke up and put gloss on, like he was ready to suck dick first thing in the morning, and boy does he ever. It’s been barely two minutes when Kyungsoo can feel the bottle slipping out of his hand as he gasps and groans through the heavenly onslaught. He pounds the wall behind him with his fist as he swears, “Christ, Jongin, so good, I could-- do you want me to come?”
He looks down for Jongin’s answer, and that was a mistake. Because he’s coming now regardless. Jongin’s eyes are turned up at him with a glossy stare, mouth stretched wide as he has Kyungsoo’s cock stuffed most of the way down his throat. His hands stop roaming along Kyungsoo’s legs and instead settle into the small dimples of his lower back muscles… and then Jongin is yanking him forward off the wall to go even deeper into him. He wants him to full on fuck his face.
“Shit, okay baby, okay,” Kyungsoo mindlessly lets the affectionate praise slip out as he pistons forward, moving in rhythm with Jongin’s tugs on his back. “Damn, you’re so good, look at you take so much, fuck.” He can feel the head of his cock pressing and pressing into the glorious give of Jongin’s throat, and listens to him whine in pleasure, like he’s enjoying this equally as much.
Kyungsoo feels his orgasm build and and build until it crests and he’s spilling into Jongin’s mouth with a long, low groan. Jongin’s eyes seem to roll with pleasure as he greedily swallows each and every pulse of come. It takes an almost embarrassingly long time for Kyungsoo to finish emptying, but Jongin wants it all and doesn’t pull off until Kyungsoo makes him.
His panting is incredibly loud as he comes down from his high, filling all the spaces of the room up. He belatedly realizes he has been petting through Jongin’s messy locks when he finally gains control over his breathing again and speaks. “Do you… want me to return the favor?”
Jongin’s head is resting against Kyungsoo’s right inner thigh. He shakes his head no in a gentle fashion, making Kyungsoo draw in a deeper breath from the accidental (accidental?) stimulation of nuzzling his balls in doing so. “Already finished,” Jongin explains, leaving a featherlight press of his lips to Kyungsoo’s thigh before changing his mind and taking a lil nip at them.
“AH,” Kyungsoo tenses, fisting Jongin’s hair again in reaction. Jongin just chuckles and laves over the spot where he nipped.
“Sorry, hyung. You’re just so yummy today.” He stands up, and his thin flannel pajama pants have an obvious come splotch over the crotch. “I’m gonna shower. Gotta head to work,” he explains.
Kyungsoo pushes his own messy hair back off his forehead and offers Jongin a V finger wave in goodbye. “You can take the cream soda on the kitchen counter with you if you want. I really had bought you your own.”
“Nah, you drink that one, and I’ll have it later,” Jongin says with a smirk. He steals one more naughty kiss from Kyungsoo’s still panting lips, and leaves.
--------------
If you had asked Kyungsoo two weeks ago if he would ever get tired of blowjobs from Kim Jongin, he would’ve looked at you like you’d had too much of Chanyeol’s homebrewed moonshine. But ever since that first day, Jongin has been insatiable, pushing more cream soda on Kyungsoo and then sucking him off with delight, reveling in the taste of his come.
This presents several problems. First, it’s screwing with his clean eating kick. “Jongin, it was a cheat day. I can’t be having cream soda daily.” He tries compromising by switching to low-sugar Gatorade, but Jongin protests he can rotate in the soda at least every other day.
Second, between hitting the gym daily and Jongin sucking him twice daily, he literally can’t stay hydrated. “I’m not a soda dispenser, Jongin.”
“But you taste so much better than one, hyung.” He’s greedy, and he’s gotten creative about it too. Blowing him in the shower, in the middle of the night in his bedroom, hell even showing up at the gym once and getting on his knees in one of the changing stalls where Kyungsoo had to ball up his sweaty workout shirt to bite it and keep his moans suppressed as the rest of the locker room went about their business. It’s exhausting, but damn does it make Kyungsoo feel studly.
Most recently and ridiculously, Jongin follows him into their apartment’s office and plops down on the carpet right next to the desk chair, patting it for Kyungsoo to take. This is only minutes after Jongin found him in the kitchen, sat him on the quartz countertop next to a live burner, and promptly blew him while Kyungsoo was trying to make breakfast. (The soondubu jiggae boiled down to an inedible gruel - Kyungsoo couldn’t stir it without sloshing because Jongin was noisily slurping his cock. He eventually gave up cooking and just braced both hands on Jongin’s shoulders instead as he bobbed up and down.) And now he’s giving Kyungsoo this kittenish grin as he’s trying to get into the office chair to get a work assignment done.
“Jongin, I literally just came.” This protest is not terribly convincing given that Jongin has already pulled down Kyungsoo’s athletic shorts and he’s stepping out of them like the whipped fool he is.
“I know, I can be patient,” he smiles up at Kyungsoo from the floor, legs folded neatly underneath him. And he has the audacity to add with a purr, “I need all ya cream, Soo-yah.”
And that’s how Kyungsoo winds up bare-assed in the high-backed, rolling office chair while trying to write his article submission in time for a deadline. Jongin is playing some bubble pop game on his phone with Kyungsoo’s soft dick in his mouth like this is a normal Tuesday, giving it tremulous licks every so often in encouragement. Kyungsoo tries not to crush his head with his thighs each time he does it (with.. moderate success). At the first leak of precome, Jongin is sucking on Kyungsoo like the world is ending and it's his last chance to give head. Kyungsoo has to roll the chair backward because it’s too much too soon--
“Jongin, I am dry. And ~someone~ made me burn my soup, so I don’t see the situation improving in the next hour.” He chugs his water bottle and mentally revisits last night’s conversation in Jongin’s bedroom.
Where he told Jongin that he really wants to fuck. Or be fucked. Both good. Not like Jongin isn’t incredible with his mouth - he’s just really thirsting for some good ole dick in ass about now. But Jongin pouted and in total seriousness complained that would be wasting perfectly delicious Kyungsoo-nut that he could otherwise have down his throat. Then he proceeded to tell him, ‘Honestly, I don’t think I can come anymore without you on my tongue, hyung. It’s that good.’ Which definitely led to Kyungsoo pinning him down on the bed by the shoulders and fucking his mouth with abandon, filth even he thought he wasn’t capable of spilling from his mouth as he did so, seeing Jongin’s satisfied smile at getting his way. ‘Since when are you such a cumslut, damn, you and this whore mouth of yours, you’ll be the death of me.'
While Kyungsoo is on this head trip, he actually gets hard again, and Jongin makes sure not to waste it. Kyungsoo really can’t imagine he’s spurting anything of consequence at this point, but Jongin is pleased as punch with himself at the end of his short-lived, shaky orgasm.
“I think… you’ve gotten… all I can give today, Jongin,” Kyungsoo grunts as he finishes. “I have to get this article in by 4pm.”
Jongin’s phone starts going off, and he lets Kyungsoo’s dick slip out of his mouth with a plop. He takes the phone call and heads out of the office, giving Kyungsoo time to collect himself (and his shorts off the ground). Kyungsoo runs a hand through his long fringe and wonders if he's sweaty enough that he needs another shower. No, he's on a deadline. He pulls the shorts on and ties the drawstring into a complicated knot that even he might struggle to undo because these cannot come off again until this evening. He's gotta focus. He hides the scissors sitting on the desk in a filing cabinet of Baekhyun’s comics for good measure. Just so Jongin doesn’t get any ideas if comes back and discovers his dick is on (temporary) lockdown.
