Dazai x Reader Smut
Dazai lounged at his desk in the Armed Detective Agency, spinning a pen between his fingers while the others chatted around him. His eyes drifted toward the door as a new figure stepped inside. The moment he saw her, everything else faded. She moved with quiet confidence, her body drawing every gaze without effort. Long hair framed her face, and her curves filled out her clothes in a way that made conversation stall mid-sentence.
Kunikida cleared his throat. "That’s our newest member. She transferred in this morning."
Dazai couldn’t look away. He had seen plenty of beautiful women, but something about her presence hit differently. She carried herself with self-respect that made every man in the room straighten up. Even Atsushi glanced twice before focusing back on his paperwork. Dazai felt an unfamiliar tightness in his chest and a sudden urge to know everything about her.
Throughout the day he kept stealing looks. Every time she passed his desk, his mind wandered to what her skin would feel like under his hands. Ranpo smirked from across the room. "Someone’s distracted today."
Dazai tried to play it off with his usual grin, but the thoughts wouldn’t stop. By afternoon he realized he was actually nervous when she finally approached to introduce herself. He leaned back in his chair, flashing his most charming smile.
"Well, well. The agency just got a whole lot more interesting. I’m Dazai. And you are… absolutely stunning."
She gave a polite nod, keeping her distance. "Nice to meet you. I prefer to keep things professional."
That only made him more determined. Over the next weeks Dazai showed up at her desk with coffee, offered to walk her home, and found excuses for long conversations. He teased her gently, complimented her mind as much as her looks, and slowly earned small smiles. She remained guarded, but he noticed the way her eyes lingered on him sometimes.
Outside the agency, the talk spread. Chuuya showed up one afternoon to drop off a file and immediately zeroed in on her. "Damn, Dazai. You didn’t tell me the new girl was this gorgeous. Every guy in Yokohama must be lining up."
Dazai’s jaw tightened. "She’s not interested in lines."
Chuuya chuckled. "Jealous much?"
The rest of the agency noticed too. Kunikida raised an eyebrow when Dazai glared at a visiting client who tried to flirt with her. Yosano smirked knowingly. "Our resident womanizer finally met his match."
Dazai realized it himself one quiet evening after everyone left. He had never felt this way about anyone. The constant parade of women he used to chase suddenly felt empty. She was different—strong, patient, waiting for something real. He wanted to be that something.
He started asking her out properly. First it was coffee after work, then dinner at a quiet restaurant overlooking the water. He listened when she talked, held doors, and kept his hands respectful until she gave signals. On their third date he reached across the table and brushed her thumb over her knuckles.
"I’ve dated a lot of women," he admitted softly. "None of them made me feel like this. You’re special. I’m falling hard."
She studied him for a long moment, then smiled. "I’ve been waiting for someone who sees more than just looks. Maybe that someone is you."
After that dinner they walked back to her apartment. The air between them crackled. At her door Dazai stepped closer, voice low and teasing.
"I’ve been thinking about you all night. The way your dress hugs every curve… it’s been driving me crazy. Can I come in?"
She unlocked the door and pulled him inside by his coat. The moment it shut behind them, her hands slid up his chest. "You’ve been teasing me for weeks, Dazai. Time to back it up."
He groaned and kissed her hard, tongue sliding against hers. They stumbled toward the bedroom, clothes coming off in a rush. He pushed her onto the bed and stripped the rest of her dress away, eyes raking over her naked body.
"Fuck, you’re perfect," he growled. He spread her thighs and lowered his mouth to her pussy, licking a slow stripe up her slit before sucking her clit. She gasped and grabbed his hair. Dazai worked her with his tongue, two fingers sliding inside her and pumping steadily while he flicked and circled her sensitive bud.
"You taste so good," he murmured against her. "Been dreaming about eating this pussy."
She moaned and tugged his hair harder. When she was close he pulled back, flipped her onto her stomach, and delivered a firm spank to her ass. The sound echoed. He spanked her again, watching the skin redden, then soothed it with his palm.
"You like that?" he asked, voice rough.
"Yes," she breathed.
He helped her turn around and sat on the edge of the bed so she could kneel between his legs. She freed his cock, wrapped her lips around the head, and took him deep. Dazai’s head fell back as she sucked him, tongue swirling, hand stroking the base. He thrust gently into her mouth, dirty talk spilling out.
"That’s it, baby. Suck my cock just like that. You look so fucking hot on your knees."
She bobbed faster, taking him to the back of her throat until he pulled her off with a wet pop. He lifted her onto the bed, positioned her on all fours, and rubbed the head of his cock against her soaked entrance.
"Tell me you want it rough," he demanded.
"Fuck me, Dazai. Hard."
He thrust in deep in one stroke, filling her completely. She cried out. He set a punishing pace, hips snapping against her ass while one hand reached around to rub her clit. Every few thrusts he landed another spank, the sting mixing with pleasure.
"Your pussy feels incredible," he panted. "So tight around my cock. You’re mine now."
She pushed back to meet every thrust. "Harder. Don’t stop."
He flipped her onto her back, hooked her legs over his shoulders, and drove into her even deeper. Sweat slicked their skin. He leaned down to suck one nipple, biting lightly before kissing her again. The bed creaked under them.
"Gonna make you come so hard," he growled against her mouth. "Want to feel you squeeze my cock when you cum."
Her orgasm hit first. She clenched around him, moaning his name as her body shook. Dazai followed seconds later, burying himself to the hilt and filling her with hot cum. He stayed inside her for a moment, forehead pressed to hers, breathing ragged.
Afterward they lay tangled together. Dazai brushed hair from her face and kissed her softly.
"I’m done with anyone else. You’re it for me. Will you be my girlfriend?"
She smiled, tracing his jaw. "Yes. I’ve been waiting for you too."
From that night on they were official. The agency celebrated with knowing smiles. Dazai still flirted outrageously, but only with her. They built a life full of late-night talks, shared missions, and passionate nights that left them both satisfied and deeply in love. Every day he woke up grateful that the woman who once walked past his desk had become his everything.
Dazai kept surprising her with small gestures—leaving notes on her desk, stealing kisses in the hallway when no one was looking, and pulling her into empty rooms for quick, heated make-out sessions. She matched his energy, teasing him back with lingering touches and whispered promises of what waited at home. The agency members watched their growing bond with amused affection, often teasing Dazai about finally being tamed.
Months later their relationship only grew stronger. They moved in together, sharing quiet mornings and intense nights. Dazai’s old habits faded completely; she became his sole focus. Their passion never cooled—every encounter remained electric, filled with the same rough intensity and tender aftercare that defined their first night. They faced missions side by side, supported each other through everything, and built a future where love and desire intertwined perfectly.
