Work Text:
Generally, Hongjoong liked to avoid the gym. He did the minimum that was required of him as an idol, but otherwise he preferred to get his exercise through running or tennis, when he could find the time for it.
There was very little that could convince him to drag himself away from work to do an hour of unscheduled strength training.
One thing that could, though, was Seonghwa.
Seonghwa could convince him of just about anything, and he knew it.
When he showed up at Hongjoong's door, wearing workout clothes and those boba eyes and a cute pout, Hongjoong was a goner before Seonghwa even opened his mouth.
"Please, Joongie? I was going to go with Sannie, but he decided to go with Yeosangie later today, and Wooyoungie and Yunho are both busy, and manager-hyung is with them."
Several possible responses ran through Hongjoong's mind.
You work out by yourself all the time. Why don't you go with Yeosang and San later? I was about to get ready to go to the studio.
But faced with his boyfriend's round, pleading eyes, all he could do was sigh and say, "Sure, just give me a minute to get ready."
The way Seonghwa's eyes lit up and he hopped inside like an excitable bunny were already worth the soreness he'd be dealing with later.
So, half an hour later, Hongjoong found himself in the company gym, following along with Seonghwa's warm-up and trying not to get too distracted staring at his bare, muscular arms and the taper from his broad shoulders to his slender waist in his fitted black tank top.
Seonghwa followed a specific workout split, each session dedicated to a different set of muscle groups. Today was an upper-body day for him.
Hongjoong was much less disciplined; he chose his workouts based on which machine gave him the best view of Seonghwa.
While Seonghwa did lat pulldowns, Hongjoong sat himself at the seated ab machine and did a few sets, but mostly watched Seonghwa—the way the cut of his tank top perfectly framed his lats flexing and bulging with each pulldown, the veins in his arms becoming more prominent, his smooth skin taking on a golden sheen as he began to sweat.
Maybe Hongjoong should start scheduling his gym sessions to coincide with Seonghwa's; if this was the view he got every time he was in the gym, he wouldn't mind going so much.
As they moved from exercise to exercise, Hongjoong was only half aware of what he was doing. Seonghwa, San, and his PT would be on him about mind-muscle connection and gym safety if they knew. But, lucky for Hongjoong, it was just him and Seonghwa here, and Seonghwa had lost himself to the rhythm of his workouts.
Hongjoong's quickened pulse and sweaty skin had nothing to do with the effort he was putting in and everything to do with how increasingly turned on he was getting watching Seonghwa.
He really couldn't believe he got to call Seonghwa his. This gorgeous person who worked so hard, never stopped pushing himself, who was strong and determined and beautiful. Who looked every bit as good lifting in gray sweats and a tank top as he did walking the runway in couture.
By the time they moved on to their fourth exercise, Hongjoong was ready to vibrate out of his skin with how badly he wanted him.
The pumping blood, heated skin, and labored breaths, accompanied by the throbbing bass of the workout playlist Seonghwa had put on—all of it made Hongjoong feel a little out of his mind.
"Joongie, can you spot me?" Seonghwa shook Hongjoong momentarily from his trance, seemingly completely unaware of the state Hongjoong was in.
He perched expectantly on a bench in front of the mirror, two 25kg dumbbells on the floor by his feet. With his hands resting curled on his knees and his eyes gazing sweetly up at Hongjoong, he looked far too cute for someone about to bench 50 kgs.
Hongjoong unstuck his tongue from the roof of his mouth. "Sure."
He stood at the head of the bench while Seonghwa got into position, kicking the dumbbells up and lying back. His head rested just beneath Hongjoong's crotch. He swallowed and his throat bobbed, and Hongjoong was suddenly all too aware of other things they could do in this position, of how easy it would be to push his shorts down and fill Seonghwa's throat with–
Then Seonghwa arched, pushing his chest up, the shape of it straining against the tight tank top.
Hongjoong forced himself to stop staring. He wouldn't get distracted and let Seonghwa end up injured just because he was pathetically horny for his boyfriend.
"Ready?" he asked, and Seonghwa nodded.
"I'm gonna go for five reps," he said.
"Okay, let me know when you need help," Hongjoong said, his hands at the ready by Seonghwa's elbows.
Then Seonghwa began, pressing the dumbbells up with a soft groan that made Hongjoong's gut clench, his cock twitching in his gym shorts.
Focus.
Two, three. Seonghwa's groans got louder. His muscles bulged. A bead of sweat trickled down the side of his face.
Four. Seonghwa's arms began to tremble. Hongjoong's cock was beginning to tent the front of his shorts.
On five Seonghwa's arms strained and shook, and he said Hongjoong's name.
Hongjoong was there immediately, hands cupping Seonghwa's upper arm and supporting him through the last rep.
When he'd successfully completed it, Seonghwa sat up and dropped the dumbbells to the floor with a heavy thud. He was breathing a little harder, and the hair at his nape was damp with sweat. Hongjoong allowed himself to stare now, memories of similar views making his cock again twitch with interest.
"Thanks," Seonghwa said, smiling over his shoulder at Hongjoong.
"No problem. You did well," Hongjoong said.
He saw the moment Seonghwa realized. He watched his eyes flick down then pause and widen slightly, his tongue darting out to lick the sweat beaded on his upper lip.
Without looking away, Seonghwa grabbed his water bottle from the floor and took several long, deep gulps. A drop of water escaped the corner of his mouth and slid down his sweat-slick throat, into the hollow of it. He lowered the bottle with a soft, satisfied sound and dragged his gaze with deliberate slowness up to Hongjoong's face.
The moment lingered, stretched taut. Neither of them spoke. Then Seonghwa slapped his thigh, the sound making Hongjoong jump slightly, and hopped up, all smiles and energy again.
"Do you want to go? Not that you really need it," Seonghwa teased, reaching over to run his palm over the ample swell of Hongjoong's chest under his t-shirt. His fingertips brushed Hongjoong's nipple, and Hongjoong flinched, inhaling sharply.
Seonghwa pretended not to notice, like it was a total accident, his eyes round and innocent.
Hongjoong shook his head wordlessly for several seconds, momentarily unable to think past his desire to push Seonghwa back onto that bench and shove his cock down his throat.
"No, I'm good," he finally said.
"Okay," Seonghwa said brightly and turned away from Hongjoong. "I've just got a couple more things to do and then we can go."
For a moment, Hongjoong only stood there in a haze of arousal, his blood rushing so loud in his ears he could barely hear the music.
He wandered his way over to the chest fly machine but didn't even pretend to be using it. He just sat and watched Seonghwa set up for his next exercise—dumbbell rows.
Facing away from Hongjoong, he bent over the bench, supporting himself on one knee and one hand. Like this, Hongjoong had the perfect view of his sweatpants stretched over his pert, round ass.
The complete lack of an underwear line was the last straw. Either Seonghwa was wearing a pair of those little seamless panties that drove Hongjoong wild, or he was going commando under his sweats. Either way, Hongjoong had to see for himself.
When Seonghwa took a break between sets, the dumbbells safely on the floor, Hongjoong moved in.
Seonghwa stood in front of the mirror, a hand on his hip, towelling the sweat from his forehead. With his head bent, he didn't see Hongjoong's approach and startled slightly when Hongjoong's hands slid, firm and possessive, over his waist.
He lowered the towel and caught Hongjoong's eye in the mirror, quirking an eyebrow in a silent question. Hongjoong saw himself over Seonghwa's shoulder, the way hunger darkened his eyes and the veins in his hands popped where he gripped Seonghwa.
"Hi," Seonghwa said, the corners of his mouth curled in amusement.
Hongjoong hummed, low and rumbling. He slid his hands over the firm plane of Seonghwa's abdomen, one hand slipping under the waistband of his sweats while the other tugged the drawstrings loose.
Seonghwa realized then how serious Hongjoong was, and his eyes went round in an expression that made him look like a startled rabbit. Hongjoong wanted to eat him whole.
His hand shot up to grab Hongjoong's wrist, stilling him for a moment, his eyes darting between their reflection and the door.
Hongjoong whined petulantly and hooked his chin on Seonghwa's shoulder. "There's no one else here. Sannie and Yeosangie aren't coming 'til later, right?" As he spoke, his fingers moved just beneath Seonghwa's waistband, rubbing circles into his hipbone.
Seonghwa's other hand hung limply by his side, the towel having slipped from it. Hongjoong took it gently and guided it between their bodies, pressing Seonghwa's palm against the prominent bulge in his shorts.
"You feel that, bunny? That's all for you," Hongjoong breathed hot against Seonghwa's ear.
Seonghwa's lips parted with a little gasp. When Hongjoong took his hand away, Seonghwa's stayed in place and curled into a firmer grip, squeezing Hongjoong's hard-on through his shorts.
The relief was incredible. Hongjoong hadn't realized just how on edge he was until then, his body going slack against Seonghwa's. His hips rocked into Seonghwa's touch and his head rested heavy against Seonghwa's shoulder.
He could feel the thump of Seonghwa's heart against his chest, his own pounding to match.
"You got this hard watching me work out?" Seonghwa asked. He sounded more breathless now than he had his entire session.
Hongjoong lifted his head to once again meet Seonghwa's gaze in the mirror. Seonghwa's eyes were bright, eager for Hongjoong's praise.
"Don't you know what you look like? What you sound like? I don't know how the other members get anything done with you around; you're so fucking sexy."
Hongjoong felt the shiver of pleasure that went through Seonghwa and smirked at him.
Seonghwa lived for praise. From his trainer, from his members, from Atiny—all he wanted was to hear how well he'd done. But there was no one's praise he craved more than Hongjoong's.
"Wanna fuck you so bad," Hongjoong continued, pressing a kiss to the firm curve of Seonghwa's delt. "Can I? I don't think I can wait until we get home."
Seonghwa's hand fell away from Hongjoong's wrist and he nodded. "Yes."
Hongjoong didn't waste a second. He shoved Seonghwa's sweats down, rough in his impatience, but he knew Seonghwa liked it that way. There wasn't anything else to get out of the way; Seonghwa wasn't wearing anything underneath. In the reflection, Hongjoong saw his bare, flushed pussy, the tell-tale shine of wetness on the insides of his thighs. On the crotch of the sweatpants now pooled around his ankles, Hongjoong saw a darkened, wet patch of fabric.
He cursed through gritted teeth and slid a hand between Seonghwa's legs to feel him, hot and slick. "You did this on purpose."
Seonghwa whined and shook his head. "I don't like wearing underwear when I work out. It feels too confining."
"So you're always at the gym like this?" Hongjoong asked, a flare of possessiveness shooting through him.
Seonghwa nodded. Though he did his best to give Hongjoong a meek bunny look, he couldn't completely hide the sparkle in his eyes, his satisfaction at knowing what this revelation would do to Hongjoong.
"I'm gonna have to start coming with you every time, then," he said.
"Will you actually let me exercise? Or just try to get in my pants?" Seonghwa said with an exaggerated pout.
"As if you wouldn't love the attention," Hongjoong retorted.
Whatever smart remark Seonghwa was going to make in return was lost to a loud, whiny moan as Hongjoong circled two fingers over his stiff clit.
"Acting so innocent, but you're already so wet for me. I think you knew exactly what you were doing."
Illustrating his point, he slid his fingers through Seonghwa's slick folds and slipped one inside, the glide so effortless. He immediately added a second, sliding it in alongside the first with a soft, wet squelch. In the mirror, he watched Seonghwa melt under his touch.
"Is that the real reason you begged me to come?" Hongjoong asked as he began pumping his fingers at an agonizingly slow pace.
Seonghwa shook his head and let out a whimper. "No, I–" he began, but cut off with a gasp when Hongjoong crooked his fingers just right.
"I don't believe you," Hongjoong murmured against the warm skin of Seonghwa's neck, his lips brushing over his racing pulse. "Your greedy pussy is sucking my fingers in. You wanted this so bad."
Seonghwa clenched hard around Hongjoong's fingers at that, only proving Hongjoong's point. He'd been keeping his noises subdued, but now a loud moan tore from him before he could stifle it, loud enough to be heard clearly over the still-blaring music. Hongjoong smirked, wicked and triumphant.
Then, just as easily as he'd slid them inside, he slipped his fingers out. Pretense abandoned, Seonghwa whined loudly in protest.
"C'mere," Hongjoong said. He maneuvered them both backward and sat heavily on the bench Seonghwa had been using, pulling Seonghwa roughly down onto his lap and shoving his thighs apart, hooking them on either side of his knees to keep him spread open.
Seonghwa went pliant, all those hard muscles slack and useless as he let Hongjoong manhandle him into position.
"Take this off," Hongjoong ordered, sliding his fingers under the hem of Seonghwa's tank top.
Seonghwa obeyed instantly, tugging the top off and tossing it carelessly aside. He then toed off his sneakers and kicked his sweats free, leaving him bare save for his calf-length Nike socks, while Hongjoong remained completely clothed beneath him.
"Fuck, bunny, look at you," Hongjoong said. He tilted his head to see around Seonghwa's broad shoulders and appreciate the picture they made in the mirror.
The muscles of Seonghwa's chest and shoulders were still pumped from his workout, his skin glistening and flushed. He was flushed between his legs, too, dusky pink and swollen and shiny wet.
Hongjoong ran a hand appreciatively up the line of Seonghwa's body that he'd always admired so much, even before he got to touch it like this. He felt the muscles twitch under his hand, the breath stuttering in Seonghwa's chest, then felt his throat bob with a hard swallow beneath his palm as he wrapped his hand around that long, gorgeous neck. He didn't squeeze too hard, applying just enough pressure to hold Seonghwa in place, back flush against Hongjoong's chest.
As he pushed his fingers back inside, he watched in the mirror the way Seonghwa stretched around them, taking him so well.
Two quickly became three, each thrust of them producing an obscene squelch as Seonghwa grew so wet he was dripping around Hongjoong's fingers. Seonghwa always got so wet for him. Before long Hongjoong's skin was soaked up to his wrist.
Under the onslaught of Hongjoong's fingers, Seonghwa gasped and moaned and squirmed atop his lap. His back arched, his eyes rolled back, lashes fluttering with the effort of keeping his eyes open so he could continue watching in the mirror.
Hongjoong was relentless, the motion of his fingers quick and rough, hitting Seonghwa's sweet spot with each thrust, rubbing it in circles.
His fingers reached deep, his palm smacking wetly against Seonghwa's cunt and stimulating his clit as well.
Seonghwa's moans grew higher, whinier, until they were desperate mewls of pleasure. His thighs trembled where they were spread across Hongjoong's lap. With each push and pull of Hongjoong's fingers came a new gush of wetness, until Seonghwa's pussy and his thighs were shining with it, and long strings of it dripped onto Hongjoong's shorts and the bench beneath them.
And Hongjoong was just getting started.
Seonghwa already looked so far gone. His head lay limp against Hongjoong's shoulder, his eyes squeezed shut, brows pinched. His gorgeous mouth hung slack, a trickle of saliva dripping from one corner and down to his jaw.
Hongjoong slid his hand up from his throat to his jaw. First, he gently thumbed away the drool. Then he grabbed Seonghwa's jaw hard, squishing his cheeks, and forced his gaze back to the mirror.
Once he was sure Seonghwa was watching again, he pushed his pinky in alongside the other three fingers. Seonghwa's cunt stretched obscenely around the four digits and squeezed them so tight it made Hongjoong groan. Even stuffed with four fingers, Seonghwa wasn't as full as he would be once Hongjoong got his cock in him, and the thought of that tight, wet heat squeezing around him had his arousal roaring even higher, his cock twitching and leaking heavily in his shorts.
"You take me so well, bunny," he panted against the underside of Seonghwa's jaw. He kissed the sharp line of it, then bit down, sucking a mark just beneath it. A place that would be impossible to cover—something he'd be scolded for later and a poor stylist would have to deal with, but it wouldn't be the first time they had to get creative covering the marks Hongjoong left on Seonghwa's skin. He couldn't find it in himself to feel bad about it, not with Seonghwa so pliant and moaning so needily in his lap.
"Hongjoong, wait," Seonghwa gasped between moans. "Oh, fuck–"
Hongjoong, so intimately familiar with every little twitch Seonghwa's body made, knew what was coming. He smirked, not letting up for a moment. He only sped up the movement of his fingers, making even more of an effort to hit Seonghwa's sweet spot dead on each time. He was moving his hand so fast, so hard, his wrist was beginning to ache with the effort of it, but that was fine—he knew Seonghwa was moments away from falling apart for him.
He felt it, the way Seonghwa's muscles were tensing, his entire body a bowstring drawing tighter and tighter.
With expert timing, Hongjoong pulled out and rubbed Seonghwa's clit with his slick-soaked fingers, rough and fast.
Seonghwa snapped. He cried out, loud and broken. His body trembled, his hips jerked, and his pussy clenched and gushed a stream of clear liquid so powerful it hit the mirror in front of them.
"That's it," Hongjoong coaxed, grinning wide and feral. He didn't care how many times he made Seonghwa do that; it would always be so hot to him. He kept moving his fingers, briefly dipping them back inside Seonghwa's fluttering hole and giving them a few rough pumps before pulling them out to rub his clit again. The relentless stimulation had Seonghwa squirting again and again, until he'd left a puddle on the floor mats beneath them.
When Hongjoong finally stopped, Seonghwa's body went completely slack. He lay heavy against Hongjoong, his head lolling on a limp neck, the only movement his chest heaving as he panted for air.
But Hongjoong didn't have it in him to be nice at the moment. He was so turned on it was painful, desire whiting out every thought except being inside Seonghwa.
He may have forced himself to hold back, except he knew how much Seonghwa loved to be used. He loved the overstimulation, the way Hongjoong's desire for him turned him greedy and insatiable.
Not giving Seonghwa a moment to catch his breath, Hongjoong lifted him off his lap so he had just enough room to shove the waistband of his shorts down and free his aching cock, then pulled Seonghwa down onto it with a bruising grip on his waist.
Seonghwa didn't have the strength to do anything but be guided where Hongjoong wanted him. He took Hongjoong's cock all at once, back arched and head thrown back. The position and the lewd expression on his face called to mind his Skin stages. Hongjoong had watched every single one on the backstage monitor, part turned on, part jealous of all the eyes and hands on Seonghwa, but mostly smug because only he got to see Seonghwa in the throes of real pleasure.
Hongjoong thrust shallowly into Seonghwa a few times, groaning. Seonghwa's pussy felt incredible around him. Even after four fingers inside, Seonghwa was still so tight. Taking Hongjoong's thick cock all at once like that was probably a lot, but Hongjoong knew Seonghwa loved the stretch, the feeling of being so full.
Sure enough, when he stilled to give Seonghwa a moment if he needed it, Seonghwa immediately turned to pout at him over his shoulder and swivelled his hips. Hongjoong hissed through his teeth, his fingers flexing on Seonghwa's waist.
"You need me to do all the work for you?" Hongjoong teased. "Come on, bunny, bounce for me. Show me how strong you are."
Despite the sulky expression on Seonghwa's face, Hongjoong knew he loved an opportunity to show off. Just like on stage, he knew exactly what he was doing and how good he looked doing it.
Bracing his hands on the bench between their legs and his feet on the floor, he began to move. His body moved in sensuous waves, his waist rolling under Hongjoong's palms, hips rocking in his lap. Like this, Hongjoong's cock glided perfectly against his sweet spot and drew the prettiest moans from him.
Hongjoong drank up the view in front of him—the glistening, flexing muscles of Seonghwa's back, the motion of his slender waist. His hands followed the path of his gaze, sliding up and down Seonghwa's body. And then, in the mirror, he could enjoy the view from the front as well. Seonghwa's golden skin glowing, the muscles of his abdomen flexing with his movement, the cockdrunk expression on his face. His dark eyes were trained between his legs, watching himself take Hongjoong's cock. Each time he sank down, a moan slipped from his parted lips.
"Look at you," Hongjoong groaned. "Taking me so well." He ran his hands over the smooth skin of Seonghwa's thighs, up between them, and traced his fingers over where Seonghwa's pussy was stretched around his thick cock.
Seonghwa looked at their reflection, then turned to look back at Hongjoong, eyes half-lidded and pleasure-dazed, teeth sunk into his plump lower lip. "Feels so good, Joongie."
Hongjoong chuckled, pleased, and leaned in to kiss him. Seonghwa melted instantly. His lips parted with a whine, welcoming the insistent push of Hongjoong's tongue. The kisses were messy, hungry, open-mouthed and wet and panting. Seonghwa was so hot and still so tight around him, the velvet slide of him quickly fraying the edges of Hongjoong's control.
As much as he enjoyed Seonghwa putting on the kind of show only he got to see, he couldn't take anymore of this slow, sensual pace. He pulled away from their kisses, stilling Seonghwa when he whined and tried to follow.
"Stand up for me," he said, patting Seonghwa's thigh.
The words didn't immediately register with Seonghwa. He blinked at Hongjoong and pouted and carried on rocking his hips in those expert rolls that made it so hard for Hongjoong to think.
Hongjoong didn't bother repeating himself. He squeezed Seonghwa's hips in a vice-like grip, forcing him to still, then shoved him off his lap. His cock slipped free, coated with Seonghwa's wetness, the head flushed a deep, angry red. He needed to cum so badly and the loss of Seonghwa's tight, wet heat around him made his jaw clench so hard the muscle ticked.
Seonghwa whined at being empty, then gasped as Hongjoong stood and roughly shoved him forward until his palms met the glass of the mirror.
Hongjoong grabbed his shoulder, fingers digging into the muscle, and shoved him down so he was bent over, braced against the mirror, and kicked his feet apart so his legs were spread and Hongjoong was able to stand between them and fuck back inside in one quick, rough go.
For a moment, they both stilled. Hongjoong bent over Seonghwa's back, meeting his gaze in the mirror. Seonghwa looked back, his expression broken open and desperate.
Slowly, not breaking his gaze, Hongjoong pulled out until only the head of his cock remained inside, then slammed forward.
Seonghwa screamed for him. His arms shook so hard Hongjoong thought he might collapse, but he managed to keep supporting himself. The glass grew damp where his hot, sweaty palms pressed against it.
One hand gripping Seonghwa's shoulder, the other his hip, Hongjoong set a brutal pace, pulling him back against each thrust.
It was funny, Hongjoong thought, how similar this sounded to them working out—the groans and grunts, the heavy breathing. If someone overheard them, they could almost get away with it. Except for the unmistakable smack of skin against skin and the way, every few moments, Seonghwa's moans pitched high and whiny.
"Fuck, you feel so good, bunny. Doing so good for me," Hongjoong groaned. He watched the effortless glide of his cock in Seonghwa's pussy, so wet that strings of slick clung to his skin each time he pulled back and dripped onto the floor.
Seonghwa's dedication in the gym had been paying off—he'd always had a cute, tight ass, but now it was beginning to fill out and it jiggled so nicely with each slam of Hongjoong's hips. The skin was reddening from the force of Hongjoong's thrusts, and he couldn't resist getting it even redder, smacking his palms against the firm curves until the skin glowed bright and Seonghwa's legs were trembling.
Having Seonghwa like this—Seonghwa, who spent so much time in the gym, with his muscles close to giving out and his skin pouring sweat—gave Hongjoong a carnal satisfaction.
"Just a little longer. I know you can take it. My strong bunny," Hongjoong cooed, sweet and vicious all at once. He pressed his chest against Seonghwa's back and kissed his sweaty temple. One hand gripped tight to Seonghwa's ass, dimpling the flesh, and the other slid to his front to press against his lower abdomen.
The response was instantaneous. Seonghwa went rigid beneath him and his pussy clenched tight around his cock as he came for a second time, gushing around Hongjoong's cock and again wetting the mirror. Hongjoong fucked him through it, revelling in the sloshing wet sound of his cock pistoning in Seonghwa's soaked pussy. Seonghwa could only take it, shaking all over from the force of his orgasm and the feeling of Hongjoong's cock still dragging against his now oversensitive walls.
The way Seonghwa throbbed around him was nearly enough to push Hongjoong over the edge too, but he didn't slow his pace or let up the pressure of his hand. His thrusts grew wilder, chasing his own climax but wanting to make Seonghwa cum one more time before he got there.
Seonghwa was limp and pliant beneath him, bouncing like a rag doll with Hongjoong's thrusts, his hands sliding and squeaking against the mirror. His head hung heavy between his shoulders, sweat dripping off his nose and chin onto the floor.
Hongjoong grabbed a fistful of his hair in a tight grip, one he knew would hurt just the way Seonghwa liked, and tugged his head up. He wanted to see how beautifully ruined Seonghwa was for him, and he wanted Seonghwa to see it for himself.
Between their heated, sweaty skin and panting breath, the gym was getting humid, the mirror growing foggy, but it was still clear enough for them to see Seonghwa's face. His skin glistened, his eyes could only barely stay open, his plump lips were parted in a perfect O, and his tongue hung slack.
Hongjoong pulled his hair a little harder to watch the way his eyes rolled back.
Seonghwa yelped at the sting and his pussy clenched hard around Hongjoong. Groaning, Hongjoong tugged again, his own eyes rolling back at the delicious squeeze of Seonghwa's cunt. His grip on Seonghwa's hair was so tight, tugging him back so firmly, it had his back arching deeper, further highlighting the ridiculous taper from his broad back to that sinful waist, then the swell of his hips and curve of his ass.
"God, you're fucking perfect for me, bunny. All that time in the gym just to look this good taking my cock."
Seonghwa's arms gave out on him then, his body falling heavy against the mirror. He could make it through 90-minute lifting sessions, but so quickly went weak and pliant under Hongjoong's attention. Hongjoong couldn't help but feel a little smug about it.
When he fell forward, Hongjoong's cock again slipped out of him. Hongjoong cursed. He was so fucking close. He plastered himself against Seonghwa's back and grabbed him under his knee, lifting his leg so he could quickly press back inside, single-minded in his need to fuck him, to cum inside him.
Seonghwa turned his head, his cheek pressed against the mirror, panting against the glass, and watched over his shoulder.
Hongjoong planted a messy kiss at the corner of his mouth, tongue swiping over his skin to taste the salty tang of sweat there. Then he pressed his forehead to Seonghwa's shoulder and looked between their flush bodies, watched Seonghwa take him as his thrusts became rougher, more uncoordinated. His cunt was so pretty like this, stretched around Hongjoong's cock, swollen and red from all the use, coated in the milky, shiny mess of his cum.
"Fuck," Hongjoong gritted out. "Gonna cum. Gonna cum inside you, bunny, gonna fill you up." He was hardly aware of what he was saying, no filter between the filthy thoughts racing through his mind and what came out of his mouth.
"Do it, please," Seonghwa panted. His voice was wrecked from all of the moans and screams of pleasure, cracking around his plea.
Hongjoong didn't need any more encouragement. After just a few more thrusts, his hips snapped forward to bury his cock deep inside Seonghwa, and he came with a long, low moan.
The orgasm crashed over him, blinding in its intensity, and all he could do was stay plastered to Seognhwa's back, panting and pressing sloppy, open-mouthed kisses to his skin, while his cock twitched and throbbed and spilled load after load inside him.
Seonghwa whined, his cunt pulsing rhythmically around Hongjoong's cock, drawing out his climax even longer, like he wanted to milk him dry.
"Greedy bunny," Hongjoong laughed breathlessly. He knew his body betrayed his cockiness with the way it trembled against Seonghwa.
Seonghwa hummed in acknowledgement, unashamed, and rocked his hips down slowly a couple of times. Hongjoong hissed through his teeth, his nails biting into Seonghwa's waist.
"Who's the greedy one? You couldn't even wait for us to get home and shower first," Seonghwa teased.
"You like it like this," Hongjoong teased right back. It was one of the many things about Seonghwa that drove him wild—how he was so scrupulously neat and clean most of the time, but when it came to sex, the wetter, messier, sweatier it was, the better.
And they had made a big mess this time. The gym reeked of sex. Seonghwa's skin had left smudges all over the mirror, not to mention the squirt dripping down the glass and puddled on the water-resistant floor. When Hongjoong pulled out, Seonghwa whined and clenched, and Hongjoong's cum flooded out of him, thick rivulets of it slipping down his skin and dripping onto the floor. They'd have to clean thoroughly before they left.
That was far from Hongjoong's mind at the moment, though. For now he just enjoyed the obscene sight of how thoroughly he'd wrecked Seonghwa.
With a lingering kiss to his shoulder, Hongjoong gently lowered Seonghwa's leg and then tugged his shorts up and moved away to grab a fresh towel from the rack by the door.
He was all soft touches and gentle words now, as he cleaned Seonghwa up as best he could.
Seonghwa, always extra needy after sex, was more than happy to stand in place and let Hongjoong take care of him, only occasionally interrupting him by pouting for kisses, which Hongjoong readily supplied.
"Come on, sleepy bunny, let's get you dressed and home," he said. He gathered Seonghwa's discarded clothes and held his sweats out for him, crouched so Seonghwa could hold onto his shoulders for balance while he stepped into them.
He turned Seonghwa's crumpled tank top so it was right side out and pulled it over his head. When Seonghwa emerged, blinking, his dark hair a mess, Hongjoong giggled and reached up to fix it. Seonghwa ducked his head to steal another kiss, Hongjoong smiling indulgently into it.
"So," Seonghwa said, slipping his arms around Hongjoong's shoulders, "Are you glad you came with me?"
Hongjoong laughed and ducked his head, exhaling an amused "aish."
When he looked up, Seonghwa was waiting expectantly for an answer, eyes twinkling and brows raised playfully.
"Yeah, you're not gonna be able to keep me away now," Hongjoong said.
Seonghwa made that smug expression of his—lips pulled into a crooked smirk, dimple popping in one cheek—and huffed a triumphant laugh through his nose.
"I knew you planned this whole thing out," Hongjoong said.
"No!" Seonghwa said, reeling back to pout down at Hongjoong. "I really wanted to work out! But you just couldn't keep your hands to yourself."
"Well, you should've known I wouldn't be able to resist you looking like that—all hot and sweaty and flexing," Hongjoong said. He wound his arms around Seonghwa's waist and squeezed lightly, pulling him back in.
Seonghwa softened instantly. "Mm, I guess you're right," he said and leaned in for another kiss.
"Now come on, we need to clean before Sannie and Yeosangie get here."
Hongjoong groaned dramatically and flopped down onto the bench.
"Come on, Joongie, you can't be that tired; you didn't even really work out," Seonghwa said, tugging on Hongjoong's arm.
"Hey," Hongjoong said, gasping in mock offence. "What do you call what we just did?" But he allowed himself to be pulled up and followed Seonghwa to where the cleaning supplies were stored.
There was, after all, nothing he wouldn't do if Seonghwa asked.
