Work Text:
The Armed Detective Agency headquarters had settled into the kind of oppressive quiet that made every tick of the clock audible. Dazai sat slumped over her desk, cheek pressed against the cool wood, one arm dangling uselessly toward the floor. No cases. No emergencies. Nothing but the suffocating weight of an empty afternoon stretching endlessly ahead.
She'd been waiting for her phone to light up for the past hour, though she'd never admit it out loud.
When it finally buzzed, she jerked upright so fast her chair scraped against the floor. Hope flared bright in her chest, then died just as quickly when she saw the notification. Wrong person. With an exaggerated groan that echoed through the office, she let her forehead thunk back down onto the desk.
"What's your problem now?" Kunikida's voice cut through the silence, already laced with exhaustion.
She answered with another theatrical groan, drawing it out until she heard him mutter something under his breath. But then her phone buzzed again, and this time the screen displayed exactly what she'd been hoping for: **My Dog <3**.
She was on her feet before the second ring, phone clutched in her hand as she bolted for the door without explanation or apology.
The hallway was blessedly empty. She pressed the phone to her ear, unable to keep the smile from her voice. "Chuuya! What's the occasion? Calling me in the middle of the workday?"
There was a pause, then that familiar low voice. "Osamu." The way she said it always made something warm unfurl in Dazai's chest. "I know we haven't had much time together lately. Do you want to come over? This afternoon. My place."
It wasn't really a question, but the slight uncertainty beneath the words made Dazai's smile soften. She caught her lower lip between her teeth. "That sounds perfect. I'll be there soon."
"Good." The line went dead immediately, no goodbye, no pleasantries. That was Chuuya. Direct. Efficient. Dazai had long since stopped expecting anything else.
She didn't bother returning to her desk. Coat in hand, she was out the door and halfway down the street before anyone could ask where she was going.
---
The walk to Chuuya's apartment did nothing to temper her anticipation. If anything, it built with every block, a pleasant hum beneath her skin. By the time she reached the familiar door, she didn't even consider knocking, just turned the handle and let herself in.
"Chuuyaaa, I'm home!" she called out, voice bright and teasing.
The redhead emerged from the kitchen wearing an oversized t-shirt and shorts, hair slightly mussed, wooden spoon still in hand. "You ever hear of knocking?" she muttered, but she was already crossing the space between them, rising onto her toes to loop her arms around Dazai's neck.
Dazai melted into the embrace, breathing in the scent of cooking and something distinctly *Chuuya*, warm and grounding. "Someone missed me."
"Don't flatter yourself." But her grip lingered a moment longer before she pulled away. "Go sit down. Dinner's almost ready."
Dazai watched as she returned to the stove, movements practiced and efficient. The kitchen filled with the quiet sounds of domesticity, the clink of the spoon against the pot, the rush of water as she rinsed dishes at the sink. It was peaceful in a way that made Dazai's chest ache.
She couldn't help herself. Rising from where she'd been leaning against the counter, she crossed the small space and slipped her arms around Chuuya's waist from behind, hands settling at her hips. She pressed close, chin resting on her shoulder.
"Dazai." There was a warning in her voice, though it lacked any real heat. "I'm busy."
"I know." Her fingers tightened slightly, thumbs tracing small circles against the fabric of her shirt.
For a moment, neither of them moved. Then Chuuya set down the dish with a sharp clatter and turned off the faucet. She turned in Dazai's arms, eyes sharp and challenging, and pushed her backward until she hit the edge of the dining table.
"Then don't complain about what happens next," she said quietly, voice dropping an octave.
"Up."
Dazai obeyed without hesitation, lifting herself onto the table's edge, pulse already quickening. She bit her lip as Chuuya stepped between her legs, wrapping them around her waist with easy familiarity.
"You think you can take control?" Chuuya murmured, leaning in until their faces were inches apart. "Let me remind you how this works."
Then her mouth was on Dazai's, fierce and claiming. Dazai groaned into the kiss, arms winding around her neck as she pulled her closer. The kiss deepened, grew messier, tongues sliding together, breath mingling, until Dazai could feel saliva beginning to slip down her chin. She didn't care. She ground her hips forward, desperate for friction, for *more*.
Chuuya's lips left hers to trail down her jaw, finding the sensitive skin of her neck. Dazai's head fell back, mouth falling open on a gasp as teeth scraped against her pulse point. Each kiss, each deliberate suck left her more undone, hips still rolling in search of pressure that wasn't there.
"Chuuya," she breathed, voice already wrecked. "Please—"
She pulled back just enough to admire her work. Dazai's lips were swollen and red, slick with spit. Her hair had come loose from its usual style, falling messily around her flushed face. And she was still grinding against nothing, desperate and needy.
"You look better like this," Chuuya said with a smirk. "Submissive suits you."
Dazai managed to flip her off, though the effect was somewhat ruined by how breathless she was. Chuuya laughed, a genuine, warm sound, and kissed her again, softer this time. Tender. Dazai smiled against her lips, feeling safe and wanted and completely undone all at once.
But the gentleness didn't last. The kiss grew heated again, aggressive, and Chuuya's hand fisted in her hair, tugging her head back. Dazai whimpered as a tongue slipped past her lips, exploring her mouth with deliberate thoroughness. At the same time, she felt fingers working at the button of her jeans, then the slow drag of the zipper.
She pulled back just long enough to tug the jeans down Dazai's legs, tossing them carelessly onto the table behind them. What remained were simple white panties, nothing special, except for the obvious wet patch darkening the fabric. Chuuya's breath hitched.
"Look at you," she murmured, pressing her palm against the soaked cotton. Dazai's hips jerked up immediately, a broken moan escaping her throat. "So wet already. Did you think about this all day?"
"Yes," Dazai gasped out, too far gone to be embarrassed. "God, yes—"
Chuuya rubbed her palm in slow, deliberate circles, applying just enough pressure to make her squirm. When her thumb found her clit through the fabric and pressed down, Dazai cried out, thighs trembling.
"Please," she whimpered. "Don't tease—"
"Patience." But she hooked her fingers into the waistband and pulled the panties aside, exposing slick, flushed skin. The sight made her groan low in her throat. She brought her thumb to Dazai's clit, rubbing in slow, maddening circles.
Dazai's hips bucked up into the touch, chasing more. She was so sensitive, so desperate, that even this light contact had her gasping. Chuuya leaned in close, lips brushing her ear as she whispered, "You're so beautiful like this. So perfect for me."
"Please," Dazai begged again, voice breaking. "I need—"
"Shh." She pressed a finger to her lips, silencing her. "I know what you need."
She teased her entrance with the tip of one finger, gathering the wetness there before slowly, slowly pushing inside to the first knuckle. Dazai's breath caught, back arching slightly. Chuuya curled her finger upward, finding that spot that made her see stars, then slid in the rest of the way.
"Fuck," Dazai breathed, head falling back.
She started with slow, gentle thrusts, letting her adjust to the intrusion. But when she felt her relax, felt her body open up, she added a second finger, stretching her carefully. Dazai moaned, long and low, as she began to move with more purpose.
Her other hand found Dazai's clit again, rubbing in time with her thrusts. The dual stimulation had Dazai trembling, thighs shaking where they were still wrapped around her waist.
"Oh god," she gasped, eyes squeezing shut. "I can't—"
"Yes, you can." Chuuya's voice was firm but gentle. "Hold on a little longer for me. You're doing so well."
In one smooth motion, she pushed Dazai down flat against the table and climbed up after her, never breaking the rhythm of her fingers. From this angle she could go deeper, faster, and she did, thrusting hard enough that Dazai's whole body jolted with each movement.
Dazai's hand flew up to cover her mouth, trying to muffle the sounds spilling from her lips, but Chuuya immediately pulled it away.
"Don't," she commanded. "I want to hear every sound you make."
"I can't, it's too much—" Dazai's voice was high and desperate, tears beginning to gather at the corners of her eyes.
"You can. Just a little more." She leaned down, capturing her mouth in a deep, consuming kiss. Dazai moaned into it, hands scrabbling at her back, gripping her shirt like a lifeline.
When they broke apart, Chuuya moved to her neck again, sucking marks into the sensitive skin as her fingers continued their relentless pace. Dazai was shaking now, teetering right on the edge, every muscle in her body drawn tight.
"Cum for me," Chuuya whispered against her ear, voice soft and commanding all at once. "Let go, baby. I've got you."
That was all it took. Dazai bit down on her lip hard enough to taste copper as her orgasm crashed over her, back arching off the table as she cried out, a broken, desperate sound that was half-sob, half-moan. Her body clenched around Chuuya's fingers, waves of pleasure rolling through her until she couldn't tell where one ended and the next began.
"That's it," Chuuya murmured, working her through it with gentle, slowing movements. "Good girl. Such a good girl."
When Dazai finally came down, she was boneless and trembling, tears streaming down her temples. Chuuya carefully withdrew her fingers and pressed soft kisses to her cheek, her jaw, her forehead, wiping away the tears with her free hand.
"You're perfect," she whispered. "So perfect."
Dazai could only manage a weak, blissed-out smile in response, still floating somewhere far away. But she felt safe. Loved. Completely and utterly hers.
Chuuya pulled back slightly, studying Dazai's flushed face with something tender and possessive all at once. "Come on," she murmured, sliding her arms beneath Dazai's trembling form. "Not done with you yet."
Dazai made a soft, incoherent sound as Chuuya lifted her from the table with effortless strength, one arm beneath her shoulders, the other under her knees. She buried her face against Chuuya's neck, breathing in that familiar scent of wine and expensive perfume, feeling the steady rhythm of her heartbeat.
The bedroom was dim, curtains drawn against the afternoon light, and Chuuya laid her down on the bed with surprising gentleness. The sheets were cool against Dazai's overheated skin, silk that whispered as she shifted. Chuuya stood at the edge of the bed for a moment, just looking at her, taking in the sight of Dazai sprawled out, still half-dressed, bandages askew and lips swollen.
"Beautiful," Chuuya said quietly, and there was no teasing in it. Just truth.
She climbed onto the bed, settling between Dazai's legs, and began to work the rest of her clothes off with deliberate care until Dazai was bare from the waist down, exposed and vulnerable in the best possible way.
Chuuya pressed a kiss to the inside of her knee, then higher, trailing her lips along the sensitive skin of Dazai's inner thigh. "You taste like heaven," she murmured against her skin. "Could spend hours right here."
Dazai's breath hitched, her hands fisting in the sheets. "Chuuya,”
"Shh." Another kiss, closer now. "Just feel."
When Chuuya's mouth finally found her, Dazai's whole body jerked with the intensity of it. The first slow drag of her tongue was deliberate, exploratory, learning every fold, every sensitive spot. Chuuya took her time, alternating between broad strokes and focused attention, building the pleasure with maddening patience.
Dazai's hips lifted involuntarily, seeking more, but Chuuya's hands pressed down on her thighs, holding her in place. "Stay still," she commanded, voice muffled but firm. "Let me take care of you."
It was torture. It was perfect. Chuuya's tongue circled her clit with just enough pressure to make her gasp, then pulled away to trace lower, dipping inside before returning to that bundle of nerves. The rhythm was unpredictable, keeping Dazai on edge, never quite enough to push her over but too much to bear.
"Please," Dazai whimpered, one hand reaching down to tangle in Chuuya's hair. "Please, I need—"
Chuuya hummed against her, the vibration sending sparks up Dazai's spine. Then she sealed her lips around Dazai's clit and *sucked*, and Dazai's vision went white.
Her back arched off the bed, a strangled cry tearing from her throat as the orgasm slammed into her. Chuuya didn't let up, working her through it with relentless precision, tongue flicking and lips pulling until Dazai was sobbing with oversensitivity, trying to squirm away even as her body chased more.
"Too much.. Chuuya, I can't—"
Only then did Chuuya ease off, pressing one last gentle kiss to her clit before pulling back. Dazai collapsed against the pillows, chest heaving, thighs trembling where they were still spread open.
Chuuya crawled up her body, leaving a trail of soft kisses in her wake, inner thighs, the curve of her hip, the soft skin of her belly. Her hands rubbed soothing circles into Dazai's sides as she moved higher, pressing kisses to the underside of her breasts, then her collarbone.
"You did so well," Chuuya murmured against her skin, voice warm with praise. "So responsive. So perfect for me."
Dazai made a soft, broken sound, turning her head to capture Chuuya's lips in a lazy kiss. She could taste herself there, salt and musk, and it sent a fresh wave of heat through her exhausted body.
"Need you," she whispered when they broke apart. "Want to feel you."
Chuuya's eyes darkened. "Yeah?"
"Please."
Chuuya sat back on her heels, finally stripping off her own clothes with efficient movements. The shirt went first, revealing the black lace bra beneath, then her pants and underwear until she was bare. Dazai drank in the sight of her, all lean muscle and pale skin, the curve of her breasts and the sharp lines of her hips.
"Come here," Chuuya said, voice low and commanding.
She guided Dazai into position, arranging their legs so they were intertwined, one of Dazai's thighs between hers and vice versa. The first brush of contact made them both gasp, wet heat against wet heat, sensitive and electric.
Chuuya started to move first, rolling her hips in a slow, deliberate grind. The friction was exquisite, their clits sliding together with each movement, and Dazai matched her rhythm instinctively. It was intimate in a way that made her chest ache, facing each other, close enough to see every flicker of pleasure across Chuuya's face, to hear every catch in her breath.
"That's it," Chuuya breathed, one hand gripping Dazai's hip to guide her movements. "Just like that. Feel how wet you are for me?"
Dazai could only nod, too overwhelmed to form words. The pleasure was building again, slower this time but no less intense. Every roll of their hips sent sparks through her core, the pressure and friction exactly what she needed.
Chuuya leaned forward, capturing her mouth in a messy kiss, all tongue and teeth and desperation. "You're mine," she growled against Dazai's lips. "Say it."
"Yours," Dazai gasped. "All yours."
The pace increased, both of them chasing their release now, movements becoming erratic and urgent. Chuuya's free hand found Dazai's breast, thumb circling her nipple in time with their grinding, and that was almost enough to push her over.
"Chuuya, I'm close—"
"Me too. Cum with me, baby. Want to feel you."
They moved together, faster now, the obscene sound of their wetness filling the room. Dazai could feel Chuuya's thigh trembling against hers, could see the way her pupils had blown wide with pleasure, and that was what did it, knowing she could make Chuuya fall apart like this.
Her orgasm hit like a wave, rolling through her in pulses that made her whole body shake. She heard Chuuya cry out at the same moment, felt her hips stutter and jerk as she came too, and they rode it out together, clinging to each other as the pleasure crested and slowly ebbed.
When they finally stilled, both panting and oversensitive, Chuuya carefully disentangled their legs and pulled Dazai close. She pressed kisses to her forehead, her cheeks, the corner of her mouth, soft and reverent.
"So good," she murmured, hands stroking up and down Dazai's back. "You're so good for me."
Dazai buried her face in Chuuya's neck, feeling boneless and sated and utterly content.
Chuuya gave her a quick kiss, then gently pushed her back against the pillows. "Stay here. I'll be right back."
She slipped off the bed and crossed to the closet, and Dazai watched through heavy-lidded eyes as she retrieved something from the top shelf. When Chuuya turned back around, Dazai's breath caught.
The harness was black leather, simple but elegant, and the toy attached to it was... substantial. Not huge, but enough to make Dazai's core clench with anticipation.
Chuuya stepped into the harness with practiced ease, adjusting the straps until it sat snug against her hips. The sight of her like that, naked except for the strap-on, all confidence and controlled power, made Dazai's mouth go dry.
"You okay with this?" Chuuya asked, climbing back onto the bed. Despite the commanding presence, there was genuine care in her voice.
"Yes," Dazai breathed. "Please."
Chuuya settled between her legs, one hand reaching for the nightstand to grab a bottle of lube. She warmed it between her fingers first, then reached down to stroke Dazai's clit with slick fingers, making her gasp and arch.
"Already so wet," Chuuya murmured appreciatively. "But let's make sure you're ready."
She worked one finger inside, then two, stretching and preparing with patient thoroughness. Dazai was already sensitive from the previous orgasms, every touch sending aftershocks through her system, but the careful attention felt good, grounding and intimate.
When Chuuya finally withdrew her fingers and positioned the toy at her entrance, Dazai's heart was racing. "Look at me," Chuuya commanded softly.
Their eyes met, and Chuuya began to push inside, slow and steady, giving Dazai time to adjust to the stretch. It was intense, the fullness almost overwhelming, but Chuuya's free hand found hers, fingers interlacing as she bottomed out.
"Breathe," Chuuya whispered. "You're doing so well."
Dazai took a shaky breath, her body gradually relaxing around the intrusion. When she nodded, Chuuya began to move, shallow thrusts at first, letting her get used to the sensation.
"More," Dazai gasped. "Please, I can take it."
Chuuya's eyes flashed with something dark and possessive. "Yeah? Want me to fuck you properly?"
"Yes, god, yes—"
The pace increased, Chuuya's hips snapping forward with controlled force. Each thrust hit deep, the angle perfect, and Dazai could feel the pressure building again impossibly fast. Chuuya's free hand slid between them, fingers finding her clit and circling with practiced precision.
"You look so good like this," Chuuya growled, voice rough with exertion and arousal. "Taking me so well. Such a good girl for me."
Dazai was beyond words now, reduced to broken moans and gasps as Chuuya drove into her. The dual stimulation, the fullness inside and the pressure on her clit, was almost too much to bear. Her hands scrabbled for purchase, one gripping Chuuya's shoulder, the other fisting in the sheets.
"That's it," Chuuya encouraged, rhythm never faltering. "Let me hear you. Want everyone to know who you belong to."
The orgasm built like a storm, pressure coiling tighter and tighter in her core until Dazai thought she might shatter from it. Chuuya must have sensed how close she was because her fingers sped up, circling her clit with just the right amount of pressure.
"Cum for me," Chuuya commanded. "One more time, baby. Give me one more."
Dazai came with a scream, her whole body convulsing as the pleasure tore through her. It was different from the others, deeper, more intense, radiating out from her core in waves that seemed endless. Chuuya worked her through it, thrusts slowing but not stopping, drawing out every last tremor until Dazai was sobbing with oversensitivity.
Only then did Chuuya carefully pull out, quickly removing the harness and gathering Dazai into her arms. She pressed kisses everywhere she could reach, forehead, cheeks, lips, shoulders, murmuring praise between each one.
"So perfect. Did so well. I've got you. You're safe."
Dazai clung to her, trembling and exhausted and utterly wrecked in the best possible way. Chuuya pulled the blanket over them both, tucking it around Dazai's shoulders before wrapping her arms around her again.
"Love you," Chuuya whispered against her hair. "So much."
Dazai managed a weak smile, burrowing closer into Chuuya's warmth. "Love you too," she mumbled, already half-asleep.
Chuuya held her as her breathing evened out, one hand stroking through her hair with infinite gentleness. In the quiet of the bedroom, with Dazai safe in her arms, everything felt right.
