"Kiss! Kiss!"

Summary:

Jelousy was irrational, Seongwha knew that. Wooyoung had been one of his best friend's for years, someone he couldn't imagine his life without...so the brief flare of boiling irritation and rage that rocked through his chest made no logical sense.

Or: Seonghwa gets jealous after the kiss on the cheek and fucks Hongjoong about it.

Notes:

Hello, welcome to 2026 :) I'm so sorry for the lack of fics last year, my mom almost died in April (right around her birthday) and I spent the next 4 months dealing with ICU doctors, bills, my dad, impending homelessness, and then the 4 months after that becoming her full time caretaker! So.... I didn't exactly have a lot of time for writing last year. (But I did see SKZ and ATZ in concert so that was a fun experience in all the other bullshit)

I hope to be able to write more this year!

(See the end of the work for more notes.)

Work Text:

Jealousy was irrational, Seongwha knew that, it was a baseless emotion that brought nothing but hurt feelings and pain for everyone involved. Wooyoung had been one of his best friends for years, someone he couldn't imagine his life without...so the brief flare of boiling irritation and rage that rocked through his chest made no logical sense.

It wasn't as if he was a stranger plastering themselves to Hongjoong's side, flirting with him. No, this was someone who knew Hongjoong was a happily taken man--one of the first who found out, actually--who wouldn't even think of leaving Seongwha. 

Wooyoung knew that they were close in ways that were beyond the simple fan service 'married couple' they portrayed on stage--the affection between the two shouldn't bother him. 

It usually didn't. 

Fan meetings had always been a whirlwind of hugs, teasing touches, and fan service that made Atiny scream in pure excitement. The sounds bounced off the walls before reverberating onto the stage where Seongwha and the other members stood, watching as their friends embarrassed themselves and each other in the name of providing entertainment.

Wooyoung's impulsive, teasing kiss on Hongjoong's cheek was no different, it was just another way to feed Atiny--and Jongho who started the 'Kiss! Kiss!' chant. Using the moment to embarrass the Captain who was known for running away from affection he didn't initiate. Taking the little amounts of PDA he was comfortable with and using it to make him blush like a school girl in front of her crush. 

Everyone in the room watched in unfiltered amusement as Hongjoong turned red and folded into himself, hiding his beet red face as the crowd and other members cheered around him. Wooyoung's face splitting in flushed triumph as he giggled in Hongjoong's face; poking at his cheek whilst the other man played into the very real embarrassment coursing through his veins.

Hongjoong laughed lightly in mock outrage before he turned towards Yeosang and stiffly wrapped his arms around him, continuing down the line of affection they were supposed to be participating in without even blinking in Seongwha's direction. Unconsciously adding to the bittered feelings boiling within his chest. 

The rest of the fan meeting went smoothly. Everyone laughed and cheered as the hours passed by...and yet, the jealousy coursing through Seongwha didn't seem to fade. Unable to meet the gaze of Wooyoung or Hongjoong in an unconsciously childish act that probably portrayed more than he wanted it to...Seongwha attempted to keep himself measured.

The jealousy built within his chest wasn't a real issue--he just needed to wait for it to pass. Allow the baseless emotion to fade into the background until it was nothing more than a forgotten moment in time...but he could still feel it clinging to him. Latched onto him like a parasite even as the group started making their way back towards the dressing room. Shoulders brushing against each other as the lingering buzz of performing sparked between them like electricity. 

"Hongjoong-Hyung," Wooyoung cooed as he moved between the others, voice cutting through the group with ease, "did you like my kiss?" he asked. Voice whiney and playful as he launched himself at Hongjoong's back, wrapping his arms around the other's neck and plastering himself to his body. Making the little monster within Seongwha's chest roar with misplaced possessiveness. 

"Oh, yes," Hongjoong sighed, making Seongwha's chest squeeze against itself. "It was a perfect kiss, I couldn't have asked for a better one." Turning in Wooyoung's hold, he moved his arms around his waist, pulling him closer. "Do you think San would share such a treat?" As he spoke his grip slowly tightened around Wooyoung's waist, holding him to his chest as he leaned closer to his face. Going in for another kiss.

"No!" Wooyoung shouted, reaching out towards a laughing Mingi in a baseless plea for help, "I don't want to kiss you again! You're gross! You're a gremlin! You're too short! You're not my Sannie!" 

"Or Yeosang!" San commented helpfully, slightly distracted from the conversation as he glanced back towards Seongwha. Watching as he hovered a few steps behind the group, staring at the back of Hongjoong's head as the man laughed, clinging to Wooyoung like a curious octopus...eyes blazing with frustrated sadness.  

"I thought you wanted my affection!?" Hongjoong shouted, laughing heartily as he continued chasing the other's face--unaware of the souring expression slowly spreading across his boyfriend's face. "I thought you loved me? I thought I was your favorite?" 

"I don't want it when you offer it to me like that!" Wooyoung yelled, reaching back with one of his hands and smashing it against his face. "Also, you severely underestimate how much I love Yeosang!" 

"You love Yeosang more than Sannie?" Mingi asked, laughter still falling from his lips as he leaned against Yunho. 

"I also love Yeosang more than Wooyoung," San says, reaching out and lightly hitting Mingi's shoulder. "It's mutual!"  

"No, it's not." Yeosang says, hiding his smile behind his hand as he watched San slump against the doorframe of their dressing room, faking a shot through the heart as he grappled at Jongho's chest. 

"So you only want my love when it embarasses me?"

The answer was obvious, Hongjoong knew that, and yet he still asked. Watching as Wooyoung finally broke free of his hold and stumbled back into Yeosang; using him as a crutch to keep himself standing. "Of course," he said breathlessly. Lips twitching into a mischievous grin as he, finally, noticed Seongwha's slightly sour face. "That's the best part about showing you affection, you get so embarrassed by it that you turn into a tiny ball of embarrassment and shame just waiting to explode. Why do you think Seongwha still puts up with you?" 

"Because Seongwha actually loves me," Hongjoong says simply, shoulders squaring with pride as he fights through the sappy smile attempting to spread across his features. "Unlike the rest of you he never tries to make me blush!" 

"Because it's a million times easier for him to fluster you than the rest of us," Wooyoung argues back, laughter spilling through the words as a soft sheen of pink slowly plastered itself across Hongjoong's cheeks. 

"Of course it's easier for him to fluster me," Hongjoong mumbled, crossing his arms across his chest and pushing through the awkwardness before quickly turning and attempting to escape the group of people intent on tattooing his skin pink. "It's Seongwha." That little mumble of his name was enough to shatter the green monster inside Seonghwa, breaking the beast into pieces and leaving an open wound of affection pouring out from within his chest. 

"I could make you more flustered if you gave me five minutes and a thong." Wooyoung said, barely concealing the way he glanced over at Seongwha, watching as the little green monster was reanimated and set aflame within his chest. 

"Do not come into the dressing room." Seonghwa grumbled as he reached for Hongjoong's hand. Latching his hand around the other's wrist and pulling him around San's still slumped over form and pushing him into the room. Ignoring the wolf whistles and teasing taunts that quickly became muffled as the door clicked shut, blocking the others from entering the room with the simple flip of the lock. 

"Seongwha?" Hongjoong whispered, turning towards the other man hovering behind him with a knowing gleam to his gaze. Twisting his wrist in Seongwha's grip in order to slide their palms together, squeezing his hand and pulling him deeper into the room. "Seonghwa, baby, you know we can't do this here." 

“So you can kiss Wooyoung in front of Atiny, but you can't kiss me, your boyfriend, in a locked room where no one will see us?” 

“What?” Hongjoong asked, voice pitching slightly as Seonghwa’s free hand trailed up his arm, squeezing indiscriminately. “I did not kiss Wooyoung, he kissed my cheek…which he does often. The amount of times all of us, not just me, have been covered in sticky lip gloss due to Wooyoung kissing us is astronomical. It's fan service, wha, you know that.” 

“He kissed you in front of everyone.” He muttered as his fingers finally reached Hongjoong's jaw. Dragging his thumb across the skin, smudging the foundation covering the marks Seonghwa left the night before, exposing them once again. Nail digging slightly into the flesh, creating a small crescent in the skin before the hickeys smoothed back out. “ I don't know why, but it bothered me today.” 

“Oh,” Hongjoong hummed, releasing Seonghwa's hand from his hold in order to move it to the other's waist. One hand groping the plushed curve of his waist while the other moved further back to grab at his ass. “Was someone feeling neglected today? Did I not portray myself as your devoted husband?” 

“No,” Seonghwa grumbled, hips twitching forward to drag his half-hard cock against Hongjoong's own. Watching with a swell of pride as his eyes fluttered with the movement—hand unconsciously tightening its grip on his boyfriend’s ass. 

“You failed.” he said with a pout, pulling Hongjoong's hand away from its grip on his ass as he sank down to his knees. Pulling the zipper of the slacks down as he finally reached the floor, licking his lips as he skillfully pulled Hongjoong's twitching cock out. The organ swelling underneath Seonghwa's heated gaze, head slightly drooling whilst heated eyes locked onto the top of Seonghwa's head. 

The sight of his boyfriend on his knees always seemed to bring Hongjoong closer to the edge than anything else. As if just knowing that Seonghwa would get on his knees for him—that all he really had to do was ask—could bring him to completion. 

“Fuck,” he groaned, hand moving down and threading through Seonghwa's hair as his breath ghosted over the shaft, “be quick, we don't know how much time we have.” 

Licking a slow stripe up the base to the tip, tongue flattened and hot as his eyes rolled back. The sweet, salted taste of sweat spread across his tongue as he mumbled: “As if that's ever been an issue for me.” Hongjoong groaned, fingers tightening around the black strands of hair tangled in his fingers; pushing lightly in an attempt to move things along. 

Leaning forward, Seonghwa wrapped his lips around the head of Hongjoong’s dick, tongue swiping across the tip and moving down the shaft as he slowly took it deeper. Throat relaxing slightly to accommodate the length stretching his throat in a familiar, comforting way. 

As the heat enveloped his cock, Hongjoong's hips twitched, bucking instinctively into the wetness surrounding his cock; pushing himself in further until Seonghwa gagged. Pulling off with a soft cough, saliva and precum spilling down his chin while a string of spit connected them to each other. Lips coated in the substance before he plunged down again, keeping a pace he knew would push Hongjoong towards the edge. 

Hallowing his cheeks while his tongue dragged against the vein on the underside of the cock taking up his mouth, making the organ twitch against his palate and ooze more precum. Soft moans fell from Hongjoong's lips, making Seonghwa drag his eyes up the others body to stare up at him; watching his face contort into pure pleasure. 

Lips parted, brows furrowed in unbidden pleasure while Seonghwa laid claim to Hongjoong's cock—wrecking him with the reminder of where he belongs. 

“Hyung—” Hongjoong groaned, hips thrusting forward to plunge deeper into the other's mouth, knowing that Seonghwa could take it. Gripping tighter onto the other's hair, fucking into his mouth with sharp snaps that drew moans from Seonghwa's throat. Vibrating around the cock in a way that sent strings of pleasure rocking up Hongjoong's spine, soft gags making Seonghwa’s throat spasm around the intrusion, his pubes brushing against the other's nose as Hongjoong's cock slid in and out. 

Coated in spit and dribbling down Seonghwa's chin as the wet glucks of a throat being filled echoed off the walls—making his throat constrict around the head. Milking it while his nails dug into Hongjoong's thigh, using it to brave himself as the hand tangled in his hair guided his head in the set rhythm. Years threatened to slide down his face from the force being applied, but Seonghwa couldn't stop himself from moaning at the feeling. 

“Fuck, Wha…” Hongjoong sighed, fingers tightening against the strands of hair being held within his palm. Possessive and consuming as he pushed Seonghwa down and ground his hips against his face, watching as dark, pleasure blown eyes gazed up at him from the floor—cock drooling into the fabric of his pants. 

Untouched and yet it cried for friction—needing Hongjoong to pay just a little bit of attention to it even if they both knew he wasn't going to. 

It was that. The knowledge that Seonghwa was so focused on claiming Hongjoong—on showing him who he belonged to in such a way that he didn't pay his own cock any attention—that made him cum. Shooting ropes directly down Seonghwa's throat as his cock pulsed in his mouth, the tongue still wrapped around the shaft tonguing at the vein as he coaxed more cum down his throat. 

Pulling off with a soft pop, Seonghwa licked the little bit of spit and cum still clinging to the head--eyes gleaming with satisfaction and pride as he wiped his mouth. Cleaning himself up from the mess Hongjoong made of his face while standing up, dragging his hands up the other's body in order to feel his heavy, pleasure wrecked breathing against his palm.

"Was that good enough fan service for you?"

"For now," Seonghwa sighed with his wrecked voice, leaning closer until their chests brushed together. "You might need to get the kids dinner later so we can make up the rest of it."

“You love me so much it makes you sick.” Hongjoong whispered with a soft laugh. Eyes gleaming with amusement and love even as a sharp slap that hit his shoulder.

Notes:

Hope you enjoyed!! Please keep in mind that most of this is not real! (The Wooyoung kissing Hongjoong's cheek is but that's it!) We don't know if they fucked after..... ;)
