Work Text:
Jongin knew it was hard for his boyfriend to come to the gym, Kyungsoo hated sweating with vigor and he hated working out, both of which mainly happened at a gym. It didn't help either that his mate had a very sensible nose and didn't fare well with all the pheromones floating around.
Yet still, after the birth of their first baby, Kyungsoo had been feeling a little insecure about his body. Jongin had tried as best as he could to make it better, had told him multiple times that he looked as beautiful as ever even if his stomach wasn't as flat as before or if his thighs were even fuller. He avoided saying just how much he liked the omega's body because he knew it was meant to start a fight, though he might have confessed it in the heat of the moment once they were being consumed by lust and desire. Kyungsoo was always gorgeous, but the fact that he had carried and given birth to their kid just made him more irresistible for the alpha.
However, Jongin knew words were just words and if Kyungsoo didn't like the way he looked it wouldn't matter that his mate was crazy over him, so he proposed going to the gym together. Jongin himself was still going for an hour every other day because he found it incredibly therapeutic, coming in with Kyungsoo would just become another bonding experience. An experience they needed with a six-month-old baby in the house. Kyungsoo agreed and they agreed that the omega's older brother would babysit their little bundle of love.
The disgusted frown Kyungsoo had the first time they walked inside the gym had pretty much remained there even if it had been a full week since they started coming, Jongin found it absolutely adorable. Today they had to come late into the night since their baby girl had been fussy and wouldn't let them leave. Thankfully she fell asleep in her uncle's hold so the two fled afterwards. Their baby is just like Jongin so once she is out, she doesn't wake up until the morning. A blessing for them as young and horny parents, Kyungsoo and Jongin made pretty good use of their nights.
Currently, they were alone in the gym. The man at the entrance had already left and since the gym in their building was open 24 hours, they could still be here even if it was technically unattended. Jongin was with his back on the bench, hoping to teach Kyungsoo how to use it properly today. So far they had covered the more basic training without any weight or machines, and stretching since Kyungsoo couldn't logically start bench pressing right away. Even if he had been cleared up by their doctor to do exercise. Jongin didn't want his mate to hurt himself, so he had been taking it slow. It was also Kyungsoo's first time ever stepping inside a gym so he didn't know shit about what to do.
"Okay, so this will help you work your chest, shoulders and arms," Jongin began explaining as he positioned himself under the barbell, hands holding it but not yet making any effort to take it off the rack. His eyes looked at his omega all the time who was staring intently at him. "It builds strength and muscle, if you're doing it correctly of course."
"But Jongin," Kyungsoo interrupted him, giving him an annoyed expression. Jongin couldn't help but give the omega's body a complete scan. Since they were alone, Kyungsoo had taken off his (the alpha's) big hoodie and was wearing just a white t-shirt that hugged his torso rather sinfully if he was being honest. He was also wearing black sports shorts, though those didn't do his thick thighs justice. The alpha looked back up once he smelt the other's annoyed scent. "I want to get rid of my belly, not build arms , shoulders and chest." Kyungsoo mocked his voice and pulled his shoulders up as he did his impression of most built dudes flaunting how ripped they were.
Jongin laughed, momentarily taking his hands off the barbell and smiling at the omega. Kyungsoo's one insecurity was his belly, even if it wasn't nearly as big as when he was pregnant or a few months ago, somehow it still bothered him. Jongin tried to understand but he couldn't, the only thing in his mind whenever Kyungsoo opened up to him was just how much Jongin wished to have his hands all over that gorgeous body of his. The things he wanted to do… the alpha knew he shouldn't think that about the father of his child, but this was Kyungsoo. The omega had been his lover before he was his mate or even gave him a child, Jongin knew damn well all the criminal things Kyungsoo could do with that body. It was hard to say the least. In more ways than just the obvious.
"Well, everything will come in due time, baby." Jongin winked at him, hands going to the barbell once again as he instructed how to position himself correctly. "Now, overhand grip on shoulders width level. Plant your feet on the floor and clamp back your shoulder blades. Breathe in and lower the bar until the middle of your chest. With your chest muscles you push the bar back to the rack while breathing out. Repeat."
He did five consecutive reps to show Kyungsoo how to properly do it. He also made the mistake of not looking at his mate so he was more than a little surprised when after resting the bar back on the rack, Jongin felt the weight of Kyungsoo's body sitting on his lap, small hands steading himself on his waist. Jongin raised a brow at the unexpected change.
"You looked so hot just now." Kyungsoo confessed, biting his lower lip.
Now Jongin could smell the change of scent in the air, the arousal so clear and evidently in the dark doe eyes staring at him.
Totally affected by it, Jongin growled as his hands kneaded the thighs straddling him, fingertips squeezing the flesh roughly. They were so soft and pliant under his touch, it was maddening. His hands didn't stay there for long though, they moved to Kyungsoo's hips and under his shirt as fast as lightning, immediately massaging the body. The omega closed his eyes above him, back arching forwards.
"You always look hot, baby." Jongin groaned, feeling himself grow hard under Kyungsoo's squirming. He also felt the way the omega's shorts were already starting to get wet. This was not supposed to happen but he couldn't possibly find it in himself to stop now. Bench pressing long forgotten.
His hands pulled Kyungsoo's shirt up to reveal his torso, from the perky dark nipples and full chest to his cute pudgy tummy. Another growl left his mouth once his hands started roaming the exposed skin, fondling with the nipples and making the omega cry out, half choking out a moan. His hands squeezed Kyungsoo's stomach and he sat up to give it the love it deserved. His mouth locked in a patch of skin, mouthing it, kissing it and sucking a nice hickey there. The alpha proceeded to bite another spot, being encouraged by Kyungsoo pulling him forward by the head.
He leant back, admiring the previously white canvas now scattered with pink hues. Kyungsoo's skin was glistening with his spit and his chest was heaving, a look of complete daze on his face. "Look at you, so beautiful, my little marshmallow." Jongin's hands squeezed Kyungsoo's ass as the omega moaned at his words.
The sound was addicting and his mate's scent was driving his alpha crazy. He wanted to devour Kyungsoo. Jongin was glad they were all alone so he could have his way right then and there.
"Sit on my face, baby."
"W-what?" Kyungsoo asked breathlessly. "J-jongin, I'm heavy. We're in the gym."
The alpha shook his head right away, hands still groping his ass under the shorts. "We are alone and you're not heavy at all. I wanna have a taste."
Kyungsoo groaned as he stood up on shaky legs, Jongin helped him steady himself and ripped the offending white material that had fallen once again and covered Kyungsoo's body. The omega let out a squeak yet melted as the alpha started peppering his stomach with kisses again, greedy hands pushing his shorts down and fondling with his slicked entrance. However, just as Jongin was getting impatient, so did Kyungsoo.
The omega pulled him away by his hair and before Jongin even managed to growl back, Kyungsoo had already gotten him out of his own shirt and pushed him down back onto the wide bench. Jongin licked his lips in anticipation and watched as a beautifully naked omega straddled his chest backwards carefully. Then again, the alpha was so impatient he immediately grabbed the curvy hips and positioned Kyungsoo's glistening ass right above his face. Jongin felt in paradise with his mate asscheeks on both sides of his face. It was the first time Kyungsoo indulged him in this, so he wanted to make him feel so good he would beg him next time to just let him sit on his face.
Kyungsoo moaned deeply above him when Jongin pushed him down and his tongue easily slided inside him, tasting his velvety walls and moaning at the sweet taste of his omega. The hole clenched as his tongue probed inside mercilessly, Jongin was parting the cheeks and feeling the way Kyungsoo's slick fell down his chin. He couldn't mind it at all, he felt too blinded by the omega's scent and taste. He didn't even bother about his raging erection until Kyungsoo fell forward and started massaging it. Feeling the hands of his mate applying pressure to his hardened dick made Jongin let out a filthy groan, mouth parting away from the ass enough to witness the puffy hole clench around nothing and a gush of slick come out of it. Jongin licked it right up, lapping the skin like a parched man.
"Fuck, you taste amazing, baby." His tongue entered Kyungsoo again, tongue fucking his mate thoroughly, until his jaw hurt. "So sweet, my little marshmallow."
"Fuck, alpha!" Kyungsoo groaned, arching his back and pushing his tongue further into him One of Jongin's hands slapped Kyungsoo's ass.
"Don't curse at your alpha baby, that's not very nice of you."
Kyungsoo's body shook above him, getting hit by waves of shivers as Jongin spoke to him huskily. His throat was affected by having spent the whole time with his tongue deep inside his ass.
"A-alpha," the omega whined when Jongin plunged two fingers inside him, his mouth too busy lapping at his asscheeks. He was biting and sucking the hot skin, everywhere where he could he was leaving a mark. Although the best and most important mark he had ever left was currently decorating Kyungsoo's right shoulder. They had claimed each other five years ago and yet Jongin still couldn't quite believe it. Kyungsoo was his just as Jongin was Kyungsoo's. He left a loving peck right where the omega's tailbone would be, hands coming to massage the round cheeks.
The omega whined when Jongin stopped his ministrations, sulkily moving backwards so as to get more. Jongin just chuckled in response, loving a little too much when Kyungsoo got this needy.
"Take off my pants so your alpha can fuck you, baby." The omega looked back at him with wide doe teary eyes and then he smirk, nodding his head in agreement.
It didn't take long for Kyungsoo to push Jongin's sweatpants out of the way and moan at what he found there. The alpha's hard dick sprung out from the pants — Jongin had gone to the gym not wearing any underwear. It wasn't something that he did everyday, just when Kyungsoo decided they were having a gym date. Then the alpha wanted to be ready at all times since, clearly, their escapades to the gym usually meant his omega got turned on by Jongin working out, what meant they were usually fucking somewhere .
As much as Jongin wished to tease Kyungsoo for that breathless gasp he let out, his words died on his throat as Kyungsoo quickly crawled back to his lap, not waiting a moment before burying Jongin's dick all the way. The alpha's back arched from the bench this time as his mate started riding him reverse cowgirl style, letting out sinful sounds as if the squelching ones of his slick weren't enough to drive him mad, he had Kyungsoo moaning with his deep alluring voice. Jongin couldn't do much but lay back and help his mate. His hands grabbed onto the omega's buttcheeks and spread them to have a full view of the way his hole stretched around his cock, pink and glistening just as much as his own dick was as he got swallowed down again and again.
"Fuck, baby, you are gonna make me put a child in you again if you keep that up." Jongin groaned, having had too much of that sight and hitting his head against the bench to calm himself and not cum right away.
His words didn't seem to faze Kyungsoo, who even though his thighs were burning and trembling kept fucking himself on Jongin's dick while moaning.
"Do it, alpha, do it if you can." The omega uttered, steadying himself on Jongin's bent knees.
His alpha took the teasing as a clear challenge and Jongin didn't fare well when being challenged. Least of all when it was his own mate pushing his buttons.
Jongin sat up and growled huskily before hugging the omega's body and preventing him from riding him. There was no time for Kyungsoo to complain before the alpha was pushing him into all fours and pistoning his dick inside him without mercy. The omega gripped the bench and moaned lowly, choking with his own saliva at the feeling of being impaled by his mate. Jongin's hands started their usual dance on Kyungsoo's body, caressing his sides and squeezing his tummy in tempo with his hips. The new position allowed Jongin to hit the omega's sweet spot every time until his mate was mumbling nonsense.
Even if his mind was a mess of Kyungsoo Kyungsoo Kyungsoo, Jongin was still aware they weren't in their home. Even if he wanted to spill his seed deep inside of the omega until he breeded him with his pups, he knew logically that he couldn't knot Kyungsoo here. For many reasons but mainly because they couldn't stay here naked for the next hour until his knot went down and risked people seeing them. They were already pushing it with having sex for this long instead of having a quickie like they normally would.
"S-soo, baby, I'm gonna pull out." Jongin whispered sweetly into the omega's ear, knowing that Kyungsoo was aware by now that his knot was swelling.
"No," the omega shook his head, walls clamping down on him and not letting him push all the way out.
Jongin hugged his mate closer, caressing his waist and stomach as he slowed down his own hips. "Come on, baby, I'll knot you once we are home." He tried to persuade Kyungsoo, but the other was far too lost to his lust to care.
"I want it now, y-you said you'll breed me."
His inner alpha groaned and so did he, the mere idea of it had his dick twitching and his hips buckling. "Little marshmallow, don't do this to me." Jongin begged as Kyungsoo kept clenching on him, fucking himself back on his dick harshly as though Jongin wasn't already thrusting into him.
"Knot me, alpha, please, please."
Kyungsoo's shoulders began to shake as Jongin moved forward, fucking onto him harder and earning moan after moan. His dick was throbbing and he wouldn't last for much longer so he sneakily massaged the omega's chest, fingers toying with the perky nipples for a bit before he twisted both of them. His mate's whole body shook as his orgasm washed over him, his ass clamping on his dick and trapping him inside. Jongin used all his inner strength not to knot Kyungsoo right then and there, instead he helped his omega ride his high and once Kyungsoo was stated he pulled out and started pumping himself. The view of the omega's abused and dripping hole enough to help him reach his high quickly after, painting said ass with his cum.
Jongin was breathless when he finally laid back against the barbell, his knot pathetically withering down and his body all gross and sweaty. Kyungsoo turned around with sad eyes and dried tears on his cheeks, he crawled closer to Jongin with a pout.
"You didn't give it to me." He sniffled before hiding his face in the alpha's neck, undoubtedly scenting his mating mark. Jongin's hands cradled the man close and felt his own heart clench a little at the omega's soft and pained voice.
He knew it was just Kyungsoo's omega talking and thinking his alpha didn't want to knot him. Once the haze passed, the omega would understand that it was for the better. Kyungsoo would have probably nagged at him had he done what he asked of him. And yet Jongin couldn't help but feel slightly guilty now after hearing how sad his mate sounded.
"Shh," the alpha hugged him tighter and caressed his cooling skin. "When we are home I'll knot you, I promise."
Kyungsoo nipped at the skin of his shoulder. "I wanted it now,"
"Won't you want it when we are home?" Jongin asked, pinching the omega's buttcheek when he refused to answer. Kyungsoo's back and ass were dirty with slick and cum, but the omega was comfortably snuggling him without a care in the world.
"I want your knot every day, Jongin, but that can't always happen." Kyunsoo mumbled, sounding a lot more like himself. "Your kid just refuses to nap so I have to wait until the night."
The alpha laughed before nuzzling at the omega's hair, " My kid? You were begging me to put another pup in you just now."
Kyungsoo huffed as he sat up, sitting on his calves and scrunching his nose. "Let's go home now." He said before getting off the bench and starting to look for their clothes.
"Now?" Jongin asked, perplexed, once he was sitting and lazily stretching his numbed limbs. The omega turned back after only putting on Jongin's hoodie and looking so criminally good Jongin could feel his blood rushing south once again.
"Now."
And Jongin was a simple man really, when Kyungsoo wanted to go to the gym they went to the gym and when Kyungsoo wanted to go home so Jongin could knot him all night, they went home.
