Summary:

“You’re mine, hyung,” Riku whispered, thumbing over the high cheekbone on Sion’s face. Sion slipped one hand up to Riku’s head, cradling the back of it as he leaned in, pressing a gentle, tender kiss to his bottom lip.

“I’m yours,” he affirmed against his mouth, leaning in for another promising kiss, “nobody can change that.” Riku chased his lips once pulled away, desperate for confirmation that his boyfriend wasn’t going away. He needed tangible evidence that it was real, that the man in front of him wasn’t leaving, and wasn't going to disappear once his eyes opened.

(or, Riku and Sion are in a secret relationship and jealousy always seems to creep in)

Work Text:

 

This party was stupid, Riku didn’t even want to be there. Stuck in a crowded room with sweating bodies flush against one another, drinks spilled onto the wooden floor and seeping into the materials below. Music rumbled through the air like waves, Riku could physically feel the bass taking control of his heartbeat, guiding the pace with a tightening grip. It was almost dizzying, even as he stood in the kitchen, away from the larger mass of people. As he leaned against a counter he could feel his head lighten. 

 

Thankfully, through the haze of drinks and loud music, Sion was with him. His long-time, secret boyfriend, who was kind enough to accompany him to this so-called “small get-together” that his friend had planned. Small was a word, but not a word to describe it. He hated it, he wanted to leave and go into the comfort of his bed with Sion clinging up to his side. That wasn’t an option just yet, there was still some fake rule set in Riku’s brain about the polite amount of time spent there. 

 

Sion was nearby him, as he always was, lingering in his orbit like the earth to the sun. Circling around the center of his world to keep himself sane. Riku would be lying if he said Sion wasn’t the same for him. He was talking to his friends he met through a class, a beaming smile on his lips, a flicker in his eyes, and a reddening glow to his cheeks from the liquor in his cup. Riku’s cheeks were darker, hell, his whole body was flushed red, so much more than anyone else’s. Both were well into being tipsy, bodies loosening muscle by muscle. 

 

Riku takes a glance around the room, spotting couples pressed against walls, not caring of wandering eyes as their lips danced and tangled like strings, hands wandering in places they shouldn’t, breaths splitting between them. Even if he would never be one for PDA, he wishes he and Sion could be like that. Be so outward with their love and want for one another just for people to not gawk and stare. 

 

That wasn’t reality, their reality was shielded behind closed doors and hidden in gasping breaths. It’s how it had been since they met, a mutual understanding that it wasn’t the time to come out, it wasn’t the safe option for either of them and where they were in life. Riku often dreamed of moving back to Fukui with Sion, finally coming out and taking the brunt of older aunties and their judging eyes, dealing with the heartache that would be his parents finding out that their darling child was now going by the name Riku instead of Rika and getting called hyung by his younger friends. 

 

But that time wasn’t now, and he would have to settle with fleeting eyes, shutting away in their shared dorm, hidden behind walls that held more secrets than they led on. Riku blinked back to Sion, watching as his shy yet social butterfly personality shone under the kitchen lights. It made his whole body feel warm, not from alcohol, but from admiration and love. A few more people joined their circle and Sion gleamed at more of his friends arriving. They were all focused on Sion, and Riku couldn’t say he blamed them. From the second Riku met Sion his whole word shifted focus like a stage light honing in on a lead singer. 

 

Riku took another long breath, lifting his plastic cup to his lips to take a long sip of his mixture of alcohol and mystery soda that he was served from Sion. It tasted sweet at first, falling bitter and biting at his throat at the end. Sinking into the meat of his throat and spreading fire down. He shuffled his way to Sion’s side, tired of standing alone and joined the conversation. Sion looked over, his eyes glistening even brighter than before. He smiled, hesitating hands struggling to not wander to his waist and back. He licked over his lips, turning back to the group.

 

“This is Riku, my roommate.” It always hurt to hear, like a pang to the chest that rang throughout his body. He knew it was their agreed upon title, Riku had to bare his teeth and grit out the word roommate too, it never lessened the burn though. Riku gave a slight nod to the group, lips pressed in a shy line as their conversation continued on. 

 

Sion introduced everyone one by one, too many names for tipsy Riku to remember but one stuck out amongst all of them. Yeonwoo. Their hair was cropped short right at the chin, shorter than both Riku and Sion. Their eyes were wide and piercing through Sion like he was a shining jewel, which… he was, but only for Riku. Sion was Riku’s, he was claimed by the younger even if he couldn’t outwardly say it.

 

Riku could see the intent behind their eyes without words. They found Sion pretty, gorgeous even. He couldn’t even say he blamed Yeonwoo, cause Sion was the prettiest thing Riku had ever witnessed. With the way they licked their lips, batted their lashes, and smiled at everything Sion said; it made Riku’s blood run cold. 

 

It formed as a pit in his stomach, twisting and curling up into a knot that could never be unwound, tightening and tightening with each passing second. It bore itself deep into his skin, creating a black hole that sucked up all the energy in his body as the realization set in. This wasn’t someone finding his boyfriend pretty, this was someone with a crush on his boyfriend. And he couldn’t do anything about it. He bit tight onto his tongue, holding back words he wanted to speak so terribly. 

 

Something to get them away, to push them off so they know that he was already taken and no one else could have him. 

 

Riku licked his lips, wetting the areas he had bitten raw since coming to this god forsaken party. It was a habit Sion usually stopped him from continuing, pulling his bottom lip from his teeth and kissing away the nerves that caused it. That once again wasn’t an option. Riku chugged the rest of his drink, grimacing at the bitter burn it caused. He cleared his throat, averting his eyes from Yeonwoo’s wandering ones. He could see the desire hidden behind their gaze, the want, the undressing of Sion with just their mind. It disgusted Riku to watch, their unashamedly focused glare that Riku wanted to tear away. His fingers tightened around his cup, crinkling the plastic as he held down his barely contained frustration. 

 

“Sion! Let me get you another drink,” Yeonwoo suddenly spoke, their eyes glimmering with hope. Sion stopped his conversation with another friend, turning to the shorter one with a polite smile on his face. 

 

“Oh, thank you but I don’t want to get too drunk, I have somewhere to be tomorrow.” That somewhere was Riku’s bed, one of their rare days off together with no classes or work to tear them away from each other. It lessened the burn of jealousy in Riku’s chest, but didn’t smother it completely. Yeonwoo visibly deflated and part of Riku felt a bit of pride in that even if it was mean of him to do so. Yeonwoo didn’t know, it wasn’t their fault that they were unaware of the situation. 

 

Riku peaked a glance at Sion, finding him moving on from the conversation before Yeonwoo could even get another word in. He bit back a smile, not wanting to spark any confusion or suspicion. Looking down into his empty cup he could spot Sion’s hand hanging loosely by his side in his peripheral. Fingers flickering towards Riku’s own hand like they were yearning to grasp onto the larger palm. To interlace their digits until it became difficult to decipher whose hand belonged to who. 

 

Suddenly, a presence startled Riku from his thinking. A sudden force bumping into his side. Sion had been pushed off to the side, ramming his body into Riku’s. Both steadied themselves, wobbling on unsteady feet from alcohol induced dizziness. When Riku finally rested, he looked off to the source of the disruption. On Sion’s opposite side, Yeonwoo made their way between Sion and another friend. Slotting themselves into Sion’s space. 

 

Sion visibly cowered, uncomfortable from the sudden contact and direct flirting. He gave a polite, civil smile, like he did with everyone. Riku glared, eyebrows lowering to sharpen his gaze at the intruder. So recklessly causing havoc in Riku’s brain just by being around them. Riku wanted to pull Sion close, pull him away from the person who kept trying, and kept pushing boundaries despite Sion’s clear display of uneasiness. 

 

Sion looked over to Riku, eyes wavering with sadness lingering behind them. Riku pressed his lips into a line, taking a deep breath of humid air before looking down at the floor below them. He needed to get away, get Sion away from prying eyes just so they could be at peace. It was too early to leave, hadn’t stayed at the party long enough to make a polite goodbye. They needed to linger just for a bit longer, but more importantly they needed to get away. 

 

Riku side stepped from Sion, giving him more space away from Yeonwoo’s advances. Riku took the start of conversation again as an opportunity to look around, trying to find a smooth exit away where he could take his boyfriend out of the situation. Above heads of dancing college kids and clouds of humidity he could see a distant staircase, going up to an upper level that surely was less crowded than the ground floor. 

 

Riku plucked his phone from his pocket, opening Sion’s contact on his messages and sending a quick sentence before shutting it off and pushing the device back into his pocket. He could see Sion startle from the vibration, reaching into his own pocket to open up the notification. He read ‘upstairs, wait five minutes after me’ no glances, no nodding, no reaction. A silent understanding that didn’t need words. It was an out, away from the intentions of strangers. 

 

Riku took his leave swiftly after, sliding out of the group unnoticed before making his way through the crowd. He pushed through sweating frames and tipped drinks, taking gasps of hot air that only somewhat cleared his tipsy mind. He wanted to take Sion with him at that moment, but they couldn’t, not yet, that would be too obvious in a room of strangers whose opinions were more likely than not negative. 

 

Riku finally made it upstairs, opening doors until he found an empty bedroom. Bed made cleanly with decorated walls. It was quiet, only echoes of muffled music reaching the isolated space. It smelt of fresh linens, pleasant compared to the smell of beer that reeked downstairs. He sat on the bed, resting his elbows on his knees before cradling his head. 

 

He wasn’t drunk, just tipsy enough to be on the brink of being drunk. His legs felt as if they were wobbling and weak beneath him, hands feeling like they lack strength to grasp. He licked over his lips, pulling his phone out to begin the countdown of when Sion should arrive. 

 

He didn’t even know what he wanted out of this, just some air and relief from Yeonwoo was his main reasoning. He was upset that someone would even dare to stake a claim on his boyfriend, even look in his direction in that way. The rational part of his brain understood that Yeonwoo didn’t know, just as everyone else in the room, but the emotional side took control, biting back with fiery jealousy that someone could so openly display their fondness while he and Sion had to hold back. 

 

Riku fell back onto the mattress, sinking into the plushness below. His eyes fluttered shut, breathing in deep through his nose to try and calm himself down. He could hear footsteps going up the stairs distantly, perking up his ears to the sound. Doors opening and closing, hushed apologies of running into strangers, knocking against wood all flowed under the gap of the door. Riku pushed himself onto his palms, licking over his bottom lip as the door to his room was opened. 

 

Sion was there, relief showering over his face when his eyes met Riku’s. He closed the door behind him, locking it shut as he closed the distance between them. Sion knelt down to Riku’s eye level, sliding his hands across Riku’s waist and resting against the small of his back. 

 

“Thank you,” Sion whispered, eyes wide with admiration at his caring boyfriend. Riku hummed, reaching his hands to card through Sion’s light brown locks. 

 

“I hate that they did that to you,” Riku admitted, speaking through bated breaths. Sion’s head nodded slightly.

 

“I know, I hate it too.” It was spoken in an air of sadness, both understanding the situation was unfortunate yet nothing could be done just yet.  Riku leaned down, pressing his forehead against Sion’s own, finding confidence in his tipsyness to hold eye contact with him. His eyes were blown with alcohol, Riku can only imagine he looked similarly. 

 

“They just came onto you like nothing, what happened to hello? Like it was just so annoying, they were so persistent and just-” Sion hushed him with a peck to his lips, silencing him from rambling more. When Sion pulled away, he had a soft smile stretched across his face.

 

“You don’t have to worry about them, I only have eyes for you.” Sion’s hands tightened around Riku’s waist, clutching him closer than before. Their shared body heat spread like fire across them, Sion could already see the sweat forming on Riku’s neck. 

 

“I know it’s just…”

 

“Hard.”

 

“Yeah.” It was a mutual understanding. Riku hooked his head over Sion’s shoulder, breathing in his cologne deep through his nose. Calming his antsy nerves as they bounced around his body. Sion let Riku soak up the attention in their hug, running a hand up and down his spine in random shapes and patterns to soothe his anxieties. 

 

Riku wasn’t usually the jealous type, Sion was the one who held that title. But on wary nights where he was already in a weird spot, being at a party where he didn’t know anyone other than his boyfriend and a select few friends and in an unfamiliar area, it was bound that some negative feeling came up. Despite that, Sion took the emotions on with grace, knowing how painful the wringing jealousy can feel. 

 

When Riku pulled away from their hug, he rested his head once again against Sion’s. 

 

“You’re mine, hyung,” Riku whispered, thumbing over the high cheekbone on Sion’s face. Sion’s eyes closed, his long lashes fanning against his cheeks. Sion slipped one hand up to Riku’s head, cradling the back of it as he leaned in, pressing a gentle, tender kiss to his bottom lip. 

 

“I’m yours,” he affirmed against his mouth, leaning in for another promising kiss, “nobody can change that.” Riku chased his lips once pulled away, desperate for confirmation that his boyfriend wasn’t going away. He needed tangible evidence that it was real, that the man in front of him wasn’t leaving, and wasn't going to disappear once his eyes opened. 

 

Sion languidly kissed him, taking in the taste of fruity cocktails and gum so warmly. Savoring the flavors on his tongue. Sion breathed in Riku’s breaths, taking his air deep into his lungs just to push the breath back into Riku’s chest. An exchange so intimate it made the hairs on Riku’s arms stand ramrod straight, a trail of goosebumps peppering his skin. 

 

Sion pressed a soft peck to the corner of Riku’s lips, nudging his head to the side with his nose to stamp kisses along his jaw, down to the column of his neck. “Hyung,” Riku breathlessly whispered, whimpering when Sion nipped at a sensitive part of his neck. Sion hummed in question against his skin, mouthing messily at his throat with wet smacks of his lips. “Make me forget how maddening Yeonwoo is, please,” he begged. He could feel Sion smile against his damp skin, sinking his teeth into his neck. It flared with pain for a moment before burning out in pleasure, the feeling bit like alcohol, yet made Riku feel drunker than any liquor could. 

 

They shouldn’t be doing this, shouldn’t be getting hot in someone else's bed. But with mixed drinks coursing in their system they couldn’t help but throw caution to the wind. Sion couldn’t care once he heard the breathy whines getting pulled so gently from Riku’s throat, laced with desperation and want, needing comfort in a time where jealousy rang high.  And with Riku asking so nicely, how could Sion deny him? 

 

Sion rose from his knees, pushing his way onto the bed as Riku scooted up the mattress. Their kiss never breaking even as rushed hands fell to Riku’s front. Sliding up his shirt to map out warm skin. Riku’s head lolled back, eyes closing shut while Sion continued to tease at his throat. Making soft blush colored marks on his skin that were sure to fade in the morning. 

 

“They were so annoying, how could they do that to you…” Sion hummed in response, letting Riku vent out his frustrations while trying his best to get the thought off his mind. Riku’s breaths quickened as Sion’s fingers brushed over his chest, tweaking the sensitive nubs that were begging to be touched and toyed with. “It makes me so mad, you’re my boyfriend, how could they- ah, hyung-” Riku’s back bowed off the bed when Sion pinched his nipple, biting into his neck to interrupt the thought from ruminating. 

 

Sion pulled back, not wasting more time before meeting Riku’s lips again, taking his bottom lip to his teeth and pulling. Sion licked over where his teeth marked, soothing the burn before repeating the action. Leaving Riku a squirming, whimpering mess with his words muted from leaving. Sion’s fingers twisted clockwise against Riku’s chest, smiling when the thighs once limp against the bed tightened around his waist. A clear sign that the heat of their bodies was travelling downward for Riku. 

 

Sion pulled back from their kiss for only a moment, pulling his t-shirt over his head before doing the same for Riku. He boggled where flesh was shining with sweat and anticipation, with the cave of Riku’s belly quivering with want. From where Sion sat he could feel the warmth that radiated from Riku’s core, seeping through fabric with wet desperation. 

 

Sion lowered his body back down, kissing messily at his swollen lips while he worked his own pants down his thighs. “I’m… yours… Riku…” he groaned between kisses, his hot breath fanning against Riku’s. 

 

Hyung.” His voice was already broken, thick with need to be touched and pampered. “Please,” he whimpered out. 

 

“You wanna do this? Like this? Here?” Sion called off a list of questions, eyes suddenly sharp and focused on Riku’s own. He reached a hand up to cup Riku’s cheek, guiding his face to look dead at him. 

 

“If you don’t, I will cry.” Sion smiled at Riku’s words, nodding along with a bitten lipped smile. He whispered an ‘okay’ through a smile, leaning down to take his lips on his own again. Sion breathed deep into their kiss, letting his hand trail down Riku’s side, touching every mole and freckle on his skin, brushing over sensitive scars from Riku’s top surgery that made the younger twitch with interest. Sion continued his way down to Riku’s waistband, slipping his hands to the center where his belt locked tight around his hips. 

 

He made quick work of undoing it, launching the leather to the floor to quickly be joined by his pants but also Riku’s own. Leaving both completely bare to the other. Hands became lost on each other's body, feeling up hot skin and melting into it. Melding into one abomination to the point it was hard to differentiate whose hands belonged to who.  Sion ran his touch across Riku’s lower back while the younger explored the planes of his back with flat palms. 

 

Sion let his hands fall across Riku’s backside, slipping to the front where his hands flattened over his thighs. He pulled Riku’s legs apart achingly slow, dragging his nails across his inner thighs under red lines that became left in their wake. Riku’s breath caught in his throat, it always did when Sion was toying with him. So breathtaken at the beautiful human who he laid so vulnerable for, forming a kind of desperation that words couldn’t describe. 

 

Riku keened into the touch, biting back a soft moan when Sion trailed his ghostly touch up and down his thighs, purposefully missing where he wanted to be touched most. When Sion’s eyes finally trailed down Riku’s body, he was met with his wet center, dark red with his bottom growth twitching with want. Sion swallowed down his own need to touch, bearing himself into Riku’s thighs as he lowered himself to be face to face with his cunt. 

 

Slowly, he laid his tongue out, looking up from where his head lay to meet Riku’s blown out pupils, hair tousled from running hands, sweat shining on his skin like glistening water. Riku looked away as their eyes met, his cheeks flushing red from the erotic sight. Sion smiled, huffing a laugh against Riku’s cock before closing the gap. 

 

S-Sionie hyung-” Riku painfully gasped, feeling the wet muscle of Sion’s tongue flatten across him. He could feel as the tip of his tongue broke between his lips, tracing the shape in figure eights, reaching up to tease at his clit before dragging back down to his entrance. Riku fell limp against the bed, head lolling back as heat spread like lighting across his body. His heart racing and breaths panting as lewd, squelching noises echoed against the four walls surrounding them. 

 

Riku reached a hand down, tangling his fingers with Sion’s hair. 

 

“Only you…only you can do this to me…” Riku panted, thighs bunching up by Sion’s head and pinning shut, holding the elder in place between his legs. “You’re mine, hyung, hyung is mine,” he moaned between each syllable, struggling to form coherent thoughts as Sion sucked them straight out of him. 

 

Sion tilted up, shaking his head back and forth with an exposed tongue as his nose brushed against Riku’s cock, stimulating it enough to have Riku writhing against the bed. He struggled to keep still, with melodic moans stringing out of him like a symphony. Riku tugged on the strands between his digits, rocking Sion’s head against him at his pace. Sion wordlessly went along with it, enjoying how eager a jealous Riku was. 

 

Riku’s breaths only quickened, and no matter how hard he tried to silence himself the volume of his moans only grew. His eyebrows knotted together in the center, eyes pinched shut, lips bitten silent. 

 

Suddenly, Sion’s fingers made their way to his entrance, teasing over spit soaked folds as Riku keened into the touch, back arched up to close their short distance. Sion relented quickly, prodding a middle and pointer finger into his gaping hole. Riku’s mouth flew open, eyes popping wide with a choking moan that echoed off the walls. Sion raised a brow, pulling back from Riku’s cunt with a strand of spit connecting them. He could hear Riku’s protests, Riku begging for more, yet they went unheard for just a moment. 

 

“You have to be quiet, Riku. Remember, we aren’t at home.” Sion awaited a nod, stilled fingers holding their place inside the younger. He could feel the way his walls twitched around him. Riku nodded, fighting off against bucking his hips just so Sion would continue. And of course, he did. 

 

Sion slid his fingers out of Riku slowly, feeling the tight ring of his entrance stretch around him, accommodating him in like he was made for the younger. He quietly groaned to himself, watching how Riku sucked him in, pleading for more without words. Though Riku was muttering to himself, repeating ‘please, please, please’ like a hushed prayer. 

 

Sion planted his hand on Riku’s abdomen, burying his fingers in and pulling them back out at a steady pace. He felt the silken softness that surrounded him, imprinting his fingerprints into the flesh as a marker of their relationship. Leaving touches that would burn for hours to pass, all to blissfully remind the younger of their tryst. 

 

Riku writhed, his hips rolling from side to side in overwhelming pleasure, his hands fisted into the sheets below to ground himself. 

 

Sion was someone who completed things once he started, fulfilled all of his tasks and duties with care and intent. And when his boyfriend asks him to make him forget about his jealousy, he would do anything to make that happen. It just so happens that Sion was going to make him forget everything but his name, leaving no space for any thought other than the elder’s name and title. 

 

Sion slid his free hand up Riku’s body, tweaking his chest once again as his ring finger slipped into his cunt, stretching him out wider. Riku’s jaw fell slack against his chest, gasping for air as each thrust punched the breath out of him. His lips could only utter Sion’s name and please, no other word could be said as Sion played with him like a marionette. 

 

He adored it, yearned for it, craved it. Sion knew what he needed, knew how he needed to be taken care of even without words. He could see right through Riku with his gaze alone, maybe that’s why Riku never quite could meet his eyes. Sion pulled his fingers from Riku’s entrance slowly, whispering out apologies at the sensitive feeling. 

 

Sion began to crawl his way up Riku’s body, pressing his lips into his stomach, on his sternum, to the center of his neck, chin, and back to his lips. He slid his tongue into Riku’s awaiting mouth, tasting him deeper than before. Riku could taste himself on his tongue, yet didn’t recoil. He pressed into it, sliding his tongue against Sion’s until spit dribbled down their chins. 

 

Riku began to shift up the bed, hoisting himself onto his knees as Sion balanced him by his waist. He cocked his head to the side, deepening their kiss even further. And then, Riku pushed Sion down, flat on his back against the mattress. For the first time that night Sion squeaked from shock. He held himself up by his elbows, watching with piercing eyes as Riku slithered his way onto his lap, messily grinding himself against Sion’s stomach. 

 

“Fuck, Riku-” Sion grabbed onto Riku’s hip, guiding his body as he grinding into him. “Look at you,” he murmured, hissing when Riku’s ass bumped against his neglected cock. Ramrod straight and pleading for contact. Riku grinded back against Sion, letting out his own soft moans as Sion’s cock slid against his skin, tacky with precum that painted his skin in clear yet wet marks. 



Riku bent down on Sion’s lap, biting deep into Sion’s shoulders and collarbones. He was biting to leave marks, to stake his claim on his boyfriend. He needed marks to prove it, to prove all of this was real and happening. Even in spots where people couldn’t see it, it filled Riku with a sense of pride knowing that he claimed what was most important to him. Comforting him that Sion was his, nobody else’s. Riku slid his hands up and under Sion’s armpits, clawing at his back like a cat to the back of a couch. He left dark red lines behind, burning in a way that left Sion hissing in ecstasy. 

 

“Sion, no one can have you but me, no one,” Riku possessively spoke, eyes dark with jealousy of someone daring to even suggest Sion was single. It should’ve put Sion off, seeing how possessive Riku was, but truthfully, he had to resist taking Riku right then and there. 

 

“No one, I’m yours.” Riku pushed himself up, reaching behind himself to align Sion’s cock with his entrance. The sudden touch to his cock made his whole body shake, trembling with the feeling. Sion pressed his lips into a firm line as he moaned into the barrier, watching as long fingers encircled his cock, gently jerking it to press more precum to the top. Riku pulled his hand back to his face, spitting into his palm before reaching down once more, lubricating the deep purple cock. He lined the tip to himself, rocking against it before sinking down in one smooth motion. The stretch burned, but it also flooded his senses. Whiting out his vision in toe curling pleasure that coursed through his veins. 

 

His heart beat throughout his entire body, Riku wouldn’t be shocked if Sion could feel his pulse within him. Sion was no better, sinking his nails into Riku’s waist and hips with red, angry crescents being left behind in the tan skin. His ears were ringing loudly, completely and utterly overwhelmed. 

 

Riku planted his hands onto Sion’s stomach, breathing hard as he tried to regain his vision. His half lidded eyes met Sion’s, and with that the fire in him burst out. Riku slowly raised his hips up, making a show of the cock almost popping out from between his legs just to slam back down onto Sion’s hips. He repeated the motion, groaning through splitting stretches just to feel every inch of Sion’s cock mold the inside of him. 

 

He rode Sion skillfully, rising with a steady pace that only grew as Riku’s desperation to come grew.

 

That knot, that pit of anger and jealousy in him was slowly unwinding, slowly unraveling to reveal something beneath it. A burning, red hot passion inside him. Only Sion could bring it out of him. Riku clashed into Sion’s face, messily knocking their lips together as he continued to fuck himself onto Sion’s cock. Their teeth knocked together, lips bitten with tongues sliding between it all. It was messy, downright disgusting to look at but for them it was perfect. 

 

Sion’s free hand found Riku’s hair, tangling with the dark threads and pulling. Riku openly moaned into Sion’s mouth, getting swallowed whole by Sion with each passing second. Riku pulled away only for a moment, immediately feeling Sion begin to attack his shoulders and collarbones just as he did to him. 

 

“You’re mine, you’re mine, fuck Yeonwoo, fuck them and all of their friends.” Sion looked up, a sudden determination flaring in his pupils. His goal was to get Riku’s mind off of it, make him forget they even existed and affirm that Sion was his entirely. Sion took that goal seriously. 

 

Sion planted his feet into the bed, pistoning his hips up, meeting Riku halfway with slamming pressure. Riku’s whole body seized, unable to drop or raise from his held position as Sion fucked his cock into him at blinding pace. The sounds of their bodies clapping together echoed off the walls, only barely muffled by the loud music downstairs. 

 

Riku grounded himself on Sion’s shoulders, boring his fingers into the flesh as Sion took the reins. Holding his hips up as he continued to piston himself in. Every muscle in his body burned, he could feel the cramps and tightening yet he remained persistent. He was going to get Riku’s mind only focused on him. 

 

Sion reached a free hand up to pull Riku’s face to his, forcing their eyes together as Sion pushed himself in once again. “Hyung– I can’t–” Riku squirmed from the prolonged eye contact, panting against Sion messily. 

 

“Look at hyung, look at me, you can do it. Focus on me.” Riku whined high in the back of his throat, his body bouncing as Sion continued to keep his pace. His hair was clumped with sweat, clinging to his forehead like a bandage. Sion pushed it away, sliding his hand down his face until his thumb passed Riku’s bottom lip, he shoved his thumb in. Riku’s moans were muffled around the digit, yet not unheard by Sion. 

 

“It’s too much, I’m not gonna last like this,” he garbled around Sion’s thumb, his thighs tightening around Sion’s hips. The sounds of squelching wetness filled the air, worsening with each passing second of eye contact. 

 

“Good,” Sion huffed, bucking his hips deep into Riku. He angled his hips up, trying for a different angle. With that thrust, he pushed his cock directly into Riku’s g-spot. He cried out, head launching backwards as Sion continued to prod and poke at the sensitive bundle of nerves. His walls tightened endlessly, clenching around Sion with a vice grip. “I’m not gonna last either,” 

 

Riku chanted Sion’s name over and over again, only barely muffled by the thumb that found its way back to his lips. With each slam of Sion’s hips, the tightly wound string in Riku’s stomach became tauter and tauter. 

 

Nngph, hyung, I can’t last-” Riku writhed under his gaze, yet held it as his climax grew closer and closer. With one last push up into his g-spot Riku came with a silent, gasping moan. His lips fell open, trembling as his head keened backwards. His vision completely blacked out, ears blaring with piercing ringing, whole body growing taut as the orgasm crashed into him. Sion continued to wreck into him, only pulling out when his climax tipped over, jerking himself off until streaks of cum poured onto Riku’s stomach. 

 

Riku fell flat against Sion’s body, panting desperately for air from against his chest. His eyes closed, listening to the thrum of Sion’s heartbeat to bring him back to reality. Sion was no better, squeezing Riku’s hips to call him down from his high. 

 

The party was still raging downstairs, music still making its way up to the room they laid in. It was their own world away from the rest. Voices of chatterboxes and party games echoed in waves, reminding them of where exactly they were. 

 

When the smoke cleared and ringing stilled, Riku parted his eyes to look up at Sion. Both were visibly exhausted and worn thin. Fucked out beyond comprehension and covered in so many bodily fluids it was hard to differentiate whose was whose. Sion’s hair was pushed all the way back, eyes closed as he twitched in the aftershocks of his climax.

 

Riku wetted his lips with the tip of his tongue, gathering what strength he had left in him to lurch up Sion’s chest. He gently kissed Sion’s swollen lips, a silent thank you for everything that had transpired. When parted, Sion’s gaze held something new; warmth, comfort, and security. 

 

“You don’t have to worry with me, I’m all yours.” Riku blushed for the nth time that night, looking down at the ground below. 

 

“I’m sorry for being like that…”

 

“You don’t have to apologize, I probably would be the same way.” Sion reached up, tucking a strand of hair behind Riku’s ear, trailing his gentle touch down and across purplish bite marks along Riku’s shoulders. Riku reached up, touching along Sion’s matching marks.  “Even if we can’t say it yet, you’re always going to be mine.” Sion reversed the conversation, watching as the light in Riku’s eyes changed from embarrassment to shyness. It clicked in that moment for Riku. 

 

There was no more room for fear, for jealousy or envy of others. Sion was his and his only, he was Sion’s, that wasn’t going to change. Even if they have to wait to be public, wait until it's safe for the both of them, they could wait together, and when that day comes when they can be themselves freely, it wouldn’t be behind closed doors.
