Chapter Text
Boom’s vibrating out of his skin. He’s been pacing around Aou’s condo ever since he sent those flirty messages to him. Overthinking it, going back and forth between telling him to forget he ever sent it or to double down. It’s unlike him to act like this, but days— merely days without Aou has been making him a little stir crazy. He’s been craving his touch ever since their phone call, his skin itching for it, unable to focus on the simplest of tasks.
It’s insane to think about, the way Aou waltzed into his life one day, crawled inside of his heart, and never left. But Boom wouldn’t have it any other way, he’s grateful everyday that Aou was cast in the same series, that he’d taken the initiative to be friends then.
The sound of the door unlocking is all that alerts him to Aou being home. He practically runs across the empty, quiet condo to the front door, there as Aou’s pushing it open. He wraps his fingers around Aou’s wrist, pulling him inside. He walks into his space, practically chest to chest, so he can push the door closed. One hand above Aou’s head, as it clicks shut, the other against Aou’s toned chest, pushing him back against it.
“Hi,” Aou says, smiling brightly, “I—”
Boom doesn’t waste any time with words, shutting him up just as he promised. He curls the shirt between his hand, kissing him hard. Aou freezes for a moment, completely caught off guard, hands twitching in the air, his bag dropping with a thud. His hands find their way to Boom’s shoulders, gripping tightly. Boom hisses at the sensation, which allows Aou to break the kiss far too quickly, gasping for air.
Boom chases after his lips, all too eager for the taste of Aou in his mouth, but he turns his head to the side, eyes closed, his skull knocking against the door, his throat bared. His hand slides up to Boom’s neck, thumb pressing gently into his pulsepoint. Aou can surely feel the way his heart is pounding.
“Baby,” he pants, “let me catch my breath.” Boom watches the way his chest rises and falls, eyes flicking up to watch the way his Adam’s apple twitches as he swallows. He doesn’t hesitate, grasping Aou’s chin in between his fingers to keep it tilted, as he licks up his neck.
Aou shivers, causing Boom to smirk against his skin before sucking his Adam’s apple in between his lips. Aou squeezes his neck, quickly, tenderly, as his other hand scratches down his back, grasping for purchase on his hip. Boom bites the protrusion, nibbling gently.
“ Fuck ,” Aou says, breathily, “what’s gotten in to you?”
“ You ,” Boom answers, as he kisses along his neck, reaching his jawline. He sucks harshly where Aou’s jaw meets his neck, surely leaving a bruise. He doesn’t worry about the regret that might hit later for leaving such an obvious mark. He doesn’t care right now. After the separation, he needs to have every inch of Aou’s body in his mouth.
“Baby,” Aou remarks, whining, “that’s going to be a pain to cover up.”
Boom pulls away from his skin with a harsh smack, stepping back and out of Aou’s reach. Boom smirks, knowing Aou will fight back quickly, and crosses his arms.
“Fine, I’ll stop.”
“Don’t you dare stop. You tease.” Aou grabs for his arms, pulling him in closer. He twists them around, backing up as he does. Boom’s back roughly hits the door, unexpectedly, eliciting a gasp. He brings his arms around Aou’s neck, fingers interlocking.
He bats his eyelashes innocently at him. “You were complaining.”
Aou’s giving him those sultry ravenous bedroom eyes and Boom swallows, struggling to continue the teasing.
“That was not a complaint. I was just making an observation.”
Boom hums, opening his mouth to respond, but Aou cuts him off, slotting their lips together. He pushes at Boom’s lips with his tongue, until Boom opens back up for him, allowing the kiss to deepen.
He sighs, reveling in the way Aou tastes like the cherry chapstick he often applies. Aou’s hands travel up and down his sides, fingers sneaking underneath his sweatshirt and the waistband of his sweats. Boom unhooks his fingers, wrapping his arms tighter around his neck. Which causes Aou to be flush against him, impossibly close.
Boom brings up his leg, hooking it around Aou’s back as he pushes his fingers farther into the back of his pants, allowing for better access. Aou does exactly as Boom wants, grabbing a handful of his ass, squeezing roughly. Boom’s head falls back, sighing at the sensation, as his mouth disconnects from Aou’s. Who in turn bites his bottom lip in between his teeth, pulling back, before releasing it.
“You look…” Aou starts, shaking his head and huffs. “Absolutely wrecked.”
“So do you.” Boom’s still breathing deeply, his heart pounding in his chest. Aou smiles at him, unable to contain the pleasure he gets at seeing Boom like this— disheveled and euphoric. Especially knowing he’s the cause.
“Oh, I’m sure. You jumped on me as soon as I walked in the door.”
“Can you blame me?” Boom asks, blushing furiously, as his hand nervously plays with the hair at the nape of Aou’s neck. Aou’s own hands are still lightly tracing the skin underneath his clothes, up and down his ribs, causing Boom to lose his composure. “I’ve—” Boom’s breath hitches as Aou brushes the pad of his thumb against Boom’s nipple. Aou smirks, nodding as he listens intently, as if he’s not the cause of his distress. “—been going out of my mind since that phone call.”
Aou grins, suddenly just as shy, dropping his head onto Boom’s shoulder, turning his face into his neck. “Oh,” He says, “I thought it was just me.”
Boom, in turn, trails a hand down the front of Aou’s chest, although separated by fabric, he can still feel the muscles twitching beneath his touch. “Definitely not,” he swipes his other hand down his back, caressing the muscles there, “I’ve been thinking about it every moment since. Everything we said.”
Aou lifts his head up, his eyes widening in surprise, “Really?”
Boom resists the urge to smack him. Aou is always underestimating the effect he has on him, his normal confidence waning. Boom doesn’t bother using words to convey this, knowing actions are his strong suit, instead grabbing a fistful of his shirt to bring their mouths together again. Aou opens up for him instantly, allowing him to lick into his mouth.
Boom’s fingers push at his waistband, instinctively finding the space where ink marks his skin. He’s long since memorized the exact feeling underneath his fingers, no longer needing to look to find it. Aou shudders beneath his touch, his own hands clawing at Boom to bring him closer.
Boom doesn’t allow it, separating their mouths with a loud popping sound, flipping Aou so his front is pushed into the wall. He plasters his front to Aou’s back, softly and slowly moving his hips.
“Baby…” Aou whimpers, and before he can say more, before he can beg, Boom attaches his lips to his neck, licking the vein there, and biting softly, eliciting a moan.
He reaches around Aou’s hips to unclasp the button on his black jeans. He pushes them down, not bothering to take them off completely, merely pushing them down to his thighs. Boom holds Aou’s hips, running his hands up and down his thighs. Aou reaches backwards to push his head further into his neck, causing Boom to smirk against his skin. He sucks harder at a spot he knows specifically makes Aou weak, loving the way his breath catches in response.
He grinds back into him and Boom detaches from his neck to bring his own fingers up to Aou’s mouth. Boom doesn’t even need to ask, he instantly takes them in, sucking hard. He watches as his cheeks hollow as Aou’s half-lidded eyes make contact with Boom’s own, sending heat to his lower body.
Boom uses his other hand to push one side of his boxer briefs down, struggling. “Fuck,” He mumbles, frustrated. Aou stops the movements of his hips, pushing the other side down for him. He bites at Boom’s fingers, which has Boom hissing and ripping them away with a smacking sound of Aou’s lips.
“Hey,” Aou protests, pouting. Boom kisses him quickly to placate him.
“Spread your legs a bit.” Aou does as he’s told immediately, hands splayed above his head against the wall. Boom stares for a minute, at the muscles in his shoulders, in his back, at his ass, mesmerized.
“Baby, c’mon .” Boom brings his fingers to his mouth, licking them teasingly, as he locks eyes with Aou. He gives him a deadpan stare in return that Boom quickly makes disappear, his eyes widening as Boom inserts his fingers all at once, without any warning.
“Fucking hell,” Aou gasps, his curse shaky, his voice catching on every other syllable. Boom smirks as he leans forward to kiss Aou’s neck, inhaling the cologne he wears, his fingers moving slowly to give him time to acclimate.
Aou’s breath comes faster, his forehead knocking against the wall as he moans, delicious sounds that Boom wants to capture. His free hand grabs Aou’s chin, roughly turning his face towards him. Aou has a look of pure bliss in his eyes, his bottom lip caught between his teeth.
“You look so good like this,” He whispers, nosing at Aou’s jaw, before sucking at his earlobe.
“G— go faster,” Aou requests and Boom stops the movement of his fingers, clicking his tongue disapprovingly.
“Ask me nicely. Beg me ,” Boom demands, although Aou will always give in easily, he still likes it when he begs.
“Baby, please go faster,” He whines, bucking his hips, “I can’t take it anymore.”
“See, all you had to do was ask.” He moves his fingers again, pushing them deeper inside, this time moving them in tandem with the movement of Aou’s hips. This time when Aou moans, it’s filled with Boom’s name, and he’s helpless but to capture it with his mouth.
He knows he’s close, and can feel it in the way Aou’s body clenches, but he doesn’t allow him to finish, taking his fingers out, stopping contact all at once.
“What…” Aou asks, dazed, as his eyes open to Boom bringing his own fingers into his mouth, licking them clean.
“You didn’t listen to me. On our call. Remember?”
Aou groans in frustration, turning around to lean his back against the wall. Boom revels in the flush that’s spread throughout Aou’s body. “You’re cruel.”
Boom can’t help the smile that overtakes his face. “You like it.”
Aou rolls his eyes, playfully, pulling Boom toward him by his waist. “You already know I’ll do anything you want, sweetheart. Just say the word.”
He brings their mouths together, as if to seal the deal, kissing him soft and slow, their tongues pushing against each other. All their desire still evident.
“What you said on the call,” Boom murmurs softly in between the kisses that become gradually more heated with each one. “I want you on your knees.”
Aou pulls back, grabbing Boom’s hand, their fingers intertwining in second nature. He walks them to the couch, pushing Boom down by the shoulders onto it, before dropping to his knees on the floor. He’s nestled in between Boom’s thighs, grabbing for his waistband.
“Lift your hips for me, love.” Boom does as he’s told, lifting his body off the couch, which allows Aou to pull down his sweats and briefs at once, discarding them on the floor.
Aou brings his hands to grasp his thighs, squeezing them tightly and pushing them further apart. Leaning forward he presses his mouth to the skin beneath his right hand, sucking it in between his lips, surely leaving marks behind, as he trails higher. Boom grabs his hair in between one hand, the other grasping at the cushion fabric. His breathing is heavy, his heart pounding heavily in his chest.
“Aou,” He gasps out, “just suck me off already.” Aou looks up, meeting his gaze, as he continues to worship his thighs.
“Should I tell you to ask nicely?” He murmurs into his skin. Boom pulls at his hair in between his hands, causing Aou to hiss sharply.
“You said you’d do whatever I want.”
“As you wish, baby.”
Aou takes him into his mouth without any warning, a moan wracking through Boom’s body. He pulls harder at Aou’s hair, as he licks a stripe up the base. One of Aou’s hands finds its way under his shirt, skimming up his ribs, his chest. Boom’s eyes flutter shut, as he leans his head back against the cushions, Aou bringing him far too quickly to an orgasm.
He bites his knuckle in between his teeth, his body going lax as the pleasure rolls through his body, releasing.
“You know you can be loud,” Aou tells him, still in between his thighs. “I know you want to be.” Boom opens his eyes to a smug look on his face.
“You have neighbors. We’re in your living room.”
“So? Who cares?”
“ I do ,” Boom emphasizes, pulling on Aou’s biceps until he joins him on the couch.
“Baby, let them hear. I want them all to know you’re mine. I want them to know I’m taken.”
Boom rolls his eyes. “What happened to keeping us private?”
Aou trails his fingers along Boom’s cheekbones. “I mean, I want to keep the way you look absolutely wrecked when I make you cum all to myself.”
Boom flushes, pressing their lips together. “I didn’t do that for you yet.”
“Right. It’s my turn, you were so cruel to me earlier,” He pouts.
Boom laughs softly, “C’mere,” He hums, pulling Aou into his lap. He pulls at the bottom of his shirt, ripping it off.
“You too.” Boom lifts his arms up, allowing Aou to pull the sweatshirt off over his head. “Finally.”
He pulls Boom flush against his chest, bringing their mouths together in another searing kiss, rocking their hips together as he does so. Boom holds his thighs in between his hands, lifting him and standing, Aou wrapping his arms around his neck. Boom brings him to the first solid surface in his gaze, setting him down on the kitchen island. He breaks the kiss, pushing him down against the surface by his neck. Aou shivers at the cold contact on his skin.
Boom wastes no time in attaching his mouth to his exposed tattoo, tracing each line with his tongue. Aou, in turn, tugs at his hair, only causing Boom to go slower, reveling in each twitch of his body. Aou’s legs are wrapped around his waist, pulling him as closely as he can.
“Baby,” Aou whines again, not dissimilar to before, “Please.”
Boom looks up at him, slowly, as his bottom lip drags along the v of his hips.
“Yes? Use your words. Tell me exactly what you want.”
“I want you inside me.” Boom smirks at him, pressing open mouth kisses once more to his tattoo. It drives Aou crazy whenever he does this, just like the very first time Boom had it underneath his fingers.
Boom disconnects from his skin, kissing Aou intensely as he palms at his cock between their bodies. Aou can’t keep up with the kisses, moaning and panting into his mouth. Boom aligns himself before pushing into Aou, who shouts a loud, pleasure-filled curse. He swallows the rest of the moan with his tongue, moving his hips in a steady rhythm.
“You’re doing so good for me,” Boom whispers, knowing Aou thrives off praise.
He digs his nails into Boom’s shoulder as he finally goes deep enough to hit just the right spot, moving his hips faster. He’s helpless to Boom’s whims, his head thrown back in pure ecstasy. Boom sucks along his neck and collarbone, reveling in every shiver and moan that he elicits from him.
“I’m— I’m so close,” Aou tells him in between desperate pants. “Please don’t stop.”
“I won’t, baby.” Boom says in answer, helpless to the way the pet name carves its way out of his throat. He saves using them for times like these, when Aou is needy and desperate and wrecked beneath him.
Aou lets out a strangled cry, his body clenching around Boom. He finishes, panting to come down from the high. Boom only needs a few more thrusts, before his body finds a second orgasm.
“You’re amazing,” Aou tells him, his hand trailing up to cup his cheek, his thumb rubbing back and forth across his cheekbone. “That was amazing.”
“Yeah?” Boom asks, unsure, uneasy with such unbridled praise, as he always is.
“God, yes,” He says as he sits up. “Best I’ve ever had.”
Boom narrows his eyes, a rush of jealousy overtaking him at the thought of Aou with others that way. He manages to contain it though, because he knows the truth. “I’m all you’ve ever had.”
“Doesn’t make it any less true, babe.”
“We need to get cleaned up. And now your kitchen needs to be deep cleaned.”
Aou laughs, unexpectedly loud as if it’s the funniest thing he’s ever heard. “Right. We’ll worry about that tomorrow. Right now, we need to shower.”
Boom holds his hand out for Aou to hop down, intertwining their hands as they walk toward the bedroom.
“Shower with me?” Aou asks, wiggling his eyebrows.
“Are you seriously trying to go again?”
“ Noooooo ,” Aou protests, although Boom doesn’t quite believe him.
“I can see the look in your eyes.”
“I can’t help it if you’re just that irresistible,” Boom reaches forward to smack at his ass and Aou barely dodges it in time. “ But , I mean it purely innocently. Let me take care of you.”
Aou’s sincere gaze and tone has him nodding his head and agreeing, following him to the bathroom. Aou keeps his word, merely scrubbing his body gently. He initiates a few kisses, only soft and sweet pecks. The domesticity of the moment briefly overwhelms him.
“I love you,” Boom whispers softly, barely audible over the spray of the shower, as Aou digs his nails into his scalp, lathering shampoo into his hair.
“I love you too.” He echoes back without even thinking. It brings tears to his eyes, how easy Aou finds him to love. The way Aou loves him is effortless, automatic, and essential — like a heart bringing blood to the rest of the body.
Aou presses lingering kisses to the side of Boom’s face, bringing him out of his thoughts. “Don’t think too hard, baby. I love you for all you are. Despite your flaws, because of your flaws.”
Boom pouts again, turning around to look Aou in the eyes. “How do you always say these things so easily?”
“I can’t help not to.”
Boom looks down at his feet, suddenly ashamed. “I wish I could say how I feel so easily…”
“Hey,” Aou whispers, a finger under his chin, pushing until he meets Aou’s gaze again. “We’re different people, it’s easy for me, but that doesn’t mean it will be for you. I’ve already told you. I don’t need words. Just you.”
Boom wraps his arms around him, hiding his face in his neck, holding him tightly. He presses a featherlight kiss to the skin there. “You’re a dream.”
Aou huffs a soft laugh, “and you’re my dream.”
Boom pulls away. “You’re always one-upping me.” He steps around Aou’s arms to push back the shower door.
“I’m sorry, baby,” Aou’s laughing, reaching for his wrist, holding it delicately in his hands. Boom’s not mad, not really, he just wants to tease Aou. “Come back and hold me!”
Boom turns around, sticking his tongue out at Aou, using his own move against him. “Finish up and I will.” He practically bolts from the shower, grabbing a towel off the banister. He’s giggling as he hears the shower turn off, waiting for Aou to catch up to him.
Aou grabs him around the waist, picking him up and spinning them around. Boom giggles more, delighting in the easy way Aou twirls them around.
“I love when you laugh like this.”
“It’s always because of you,” Boom says honestly. He never laughs so freely except when he’s with Aou.
“Good. I think I’d be jealous if someone else made you laugh like this.” Boom holds Aou’s face in his hands, swiping his thumbs along his cheeks.
A yawn rips through him, and he changes the subject, “Let’s get dressed and sleep. I’m tired.”
“Okay, baby, whatever you want.” Boom preens, as he disconnects from Aou to grab some clothes. He has his own here, but he particularly likes wearing Aou’s to bed. Whenever they’re apart he wears Aou’s clothes as well, he always feels at home and safe in them.
He turns and Aou’s already dressed, towel drying his own hair. He climbs on the bed, next to Aou, wrapping his arms around his waist. Aou uses the towel to dry Boom’s own hair, “you can’t sleep with it wet,” he tells him. Boom nods, against his chest, his eyes closing already.
“Goodnight, love.”
“Goodnight.”
