Chapter Text
“Get over here. Now.”
The order crackled through the intercom on Chuuya’s desk, Dazai’s voice stripped of all its playful lilt, leaving only the raw, unyielding command of the Port Mafia’s boss. Chuuya’s spine straightened instantly, a jolt of pure heat shooting straight to his core. He knew that tone. It wasn’t about business.
He was in the executive office thirty seconds later, the heavy door shutting with a soft click. Dazai wasn’t at his desk. He was leaning against its front, arms crossed over his dark suit jacket, which was already unbuttoned. His gaze was a physical weight, pinning Chuuya where he stood just inside the room.
“Lock it,” Dazai said, the words low.
Chuuya turned, flicked the lock, and when he turned back, Dazai was closer. The air in the room thickened, saturated with the alpha’s scent—expensive whiskey, iron, and a musk that made Chuuya’s knees feel weak.
“You called, Boss?” Chuuya managed, his own voice betraying him with a husky edge.
Dazai’s hand shot out, fingers tangling in Chuuya’s auburn hair, not gentle, not cruel, but possessive. He yanked, just enough to make Chuuya gasp, and brought their faces close. “I didn’t call my right-hand man,” Dazai murmured, his breath hot against Chuuya’s lips. “I called my omega. And he’s late.”
Then his mouth was on Chuuya’s, and every thought evaporated.
It started tender, a slow, searching press of lips. A question. Chuuya answered by opening for him, a soft sigh escaping into Dazai’s mouth. Then the urgency took over. Dazai licked inside, claiming every part of him, the kiss turning deep and filthy. Chuuya’s hands came up, clawing at Dazai’s jacket, trying to pull him closer, to get more of that taste, that heat. They were both breathing hard when Dazai finally broke away, a string of saliva connecting them for a second before it snapped.
“On the desk,” Dazai ordered, his voice rough. He didn’t wait, shoving Chuuya backward. The edge of the massive oak desk hit the backs of Chuuya’s thighs. Dazai’s hands were everywhere, tearing at clothes, buttons pinging against the hardwood floor. Chuuya scrambled to help, shoving his own pants and briefs down, kicking them off his ankles. In moments, he was bare from the waist down, bent back over the polished wood, his cock already hard and leaking against his stomach.
Dazai finished undoing his own trousers, and Chuuya’s breath caught. Every fucking time. Dazai’s cock sprang free, thick and heavy and impossibly large. It was a weapon of its own, flushed a deep red, veins standing out along its formidable length. Chuuya’s mouth watered.
“Look at it,” Dazai said, stroking himself slowly, his eyes locked on Chuuya’s face. “Look at what you take for me. What you beg for.”
“Fuck,” Chuuya whispered, the praise and the visual going straight to his head, making him dizzy with want. “It’s so fucking big, Dazai. I love your cock. I love how fucking thick it is. I need it.”
“Yeah? Tell me what you need.”
“I need you to fuck me. I need you to ruin me on this desk. I need your fucking knot.” The words tumbled out, shameless. Chuuya spread his legs wider, presenting himself. The slick was already making a mess, dripping down his thighs. The sweet, inviting scent of a ready omega filled the office.
Dazai didn’t use his fingers. He never did, not when he was like this. He just lined up the broad, wet head of his cock against Chuuya’s entrance and pushed.
The stretch was immense. A burning, perfect fullness that stole the air from Chuuya’s lungs. He cried out, a broken sound, as Dazai sank in, inch by brutal, glorious inch, spreading him open wider than he thought possible. Dazai bottomed out, his hips flush against Chuuya’s ass, and paused, his body trembling with the effort of holding still.
“Fuck, Chuuya,” Dazai groaned, burying his face in Chuuya’s neck. “You feel like heaven. You take me so fucking well. My perfect omega.”
Then he pulled back and slammed home.
The pace was punishing from the start. Dazai fucked into him with deep, rolling thrusts of his hips, each one jolting Chuuya forward on the desk. The sound of skin slapping against skin, of Chuuya’s ragged moans and Dazai’s guttural grunts, echoed off the high ceilings. Dazai wrapped one hand around Chuuya’s throat, not squeezing, just holding, a constant reminder of his control. The other hand gripped Chuuya’s hip hard enough to bruise.
“You like this?” Dazai snarled, his thrusts getting faster, harder. “You like getting fucked stupid on your boss’s desk?”
“Yes! Yes, Dazai, fuck, just like that!” Chuuya babbled. The pleasure was a coil tightening low in his gut, white-hot and electric. Every drag of that thick cock over his prostate made him see stars. He was so full, so owned. “You feel so fucking good inside me. Don’t stop, please don’t stop.”
Dazai changed the angle, hiking Chuuya’s legs up higher, bending him almost in half over the desk. The new position drove his cock even deeper, the pressure becoming overwhelming. Chuuya screamed, his body bowing off the desk.
“That’s it,” Dazai praised, his voice a hot whisper in Chuuya’s ear. “Let me hear you. You’re so beautiful like this. So fucking sexy taking every inch. My good boy. My perfect Chuuya.”
The words, the filthy praise, tipped Chuuya over the edge. His orgasm ripped through him without warning, a tidal wave of sensation that clenched around Dazai’s cock and squeezed. A gush of fluid, not just slick, but clear and hot, erupted from him, soaking Dazai’s thighs and the carpet below. He shook through it, sobbing Dazai’s name.
“Again,” Dazai commanded, and he didn’t slow. He fucked Chuuya right through the shuddering aftershocks, his rhythm becoming erratic, brutal. Chuuya could feel the base of Dazai’s cock beginning to swell, the knot forming, stretching him even fuller.
“Dazai… Dazai, please,” Chuuya begged, mindless, his oversensitive body alight with a new, desperate need. “Knot me. Come inside me. Fill me up, I need it, I need your fucking cum, please, alpha, give it to me!”
With a final, savage thrust, Dazai buried himself to the hilt. The knot popped, locking them together, a tight, pulsating bulge that sealed Chuuya utterly full. Dazai’s release followed immediately, a hot, seemingly endless flood that pumped deep into Chuuya’s core. Chuuya could feel it, wave after wave, filling him up, a claiming so complete it felt like he was being remade from the inside. Dazai’s teeth found his mating gland, not breaking the skin, but pressing down in a dominating promise as he emptied himself.
They stayed like that, locked together by Dazai’s knot, for forty-two minutes.
Dazai slumped over him, his weight a welcome comfort, his breath hot on Chuuya’s shoulder. He kept moving, just tiny, shallow rocks of his hips, keeping his softened cock nestled inside as the knot kept them connected. Chuuya could feel the warm trickle of excess cum and slick seeping out around where they were joined, a messy, perfect proof of what they’d done.
“You took it all,” Dazai murmured, his lips moving against Chuuya’s sweat-slick skin. “Every last drop. Felt you milk me dry.” He shifted, just enough to kiss Chuuya’s shoulder, his neck, his jaw, before finding his lips again. This kiss was different—slow, deep, languid. A sensual exploration in the aftermath.
Chuuya melted into it, humming softly. He was boneless, utterly spent, so full of his alpha he could barely think. Dazai’s hand came up to cradle his face, his thumb stroking Chuuya’s cheekbone.
“My beautiful omega,” Dazai whispered against his mouth. “Look what you did. My desk is ruined. You’re ruined.” He kissed him again, sucking gently on Chuuya’s lower lip. “I’m going to keep you like this all night. Full of me. Maybe I’ll even put a pup in you this time. Would you like that? Being round with my child?”
Chuuya’s heart hammered against his ribs. He nodded, unable to form words, the idea sending a fresh, aching throb of desire through his spent body. Dazai smiled, that dark, knowing smile, and kissed him once more.
For a long, perfect moment, they were still. Dazai’s knot, that impossible, thick swell, finally softened and slipped free with a wet, messy sound. A fresh gush of warmth, Dazai’s cum mixed with Chuuya’s own slick, spilled out onto the ruined wood of the desk, dripping down his thighs. Chuuya shuddered, his whole body feeling hollowed out and used in the best way.
Dazai didn’t pull away. He stayed pressed against Chuuya’s back, his softening cock still resting in the cleft of Chuuya’s ass. His lips found the sweaty junction of Chuuya’s shoulder and neck, planting a soft, open-mouthed kiss there. “Still with me, little king?” he murmured, his voice a low rumble.
Chuuya could only manage a weak nod, his cheek pressed to the cool wood. His legs trembled.
“Good.” Dazai’s hand smoothed down the curve of Chuuya’s spine, a possessive, soothing stroke. Then it landed on his ass with a sharp, stinging smack that made Chuuya jerk. “Because I’m not done with you.”
Before Chuuya could process the words, Dazai was moving. He gripped Chuuya’s hips and hauled him upright, bending him back over the desk. Chuuya’s spent cock, already half-hard again just from Dazai’s touch, rubbed against the wood. “Again?” he breathed, the word half-protest, half-prayer.
“Again,” Dazai confirmed, his tone leaving no room for argument. He reached for the top drawer of his desk, the one Chuuya knew held things that weren’t for paperwork. The sound of the drawer opening was loud in the quiet room. Dazai pulled out a sleek, black silicone toy, thick and veined, glistening with a sheen of lubricant. “Open.”
Chuuya’s mouth fell open obediently. Dazai didn’t hesitate. He pressed the bulbous head of the toy against Chuuya’s lips, and Chuuya took it, his jaw stretching wide to accommodate the girth. The silicone filled his mouth, a heavy, artificial weight on his tongue. The taste was clean, sterile, a stark contrast to the salt and musk of Dazai’s skin.
“Suck it,” Dazai ordered, his eyes dark. “Get it nice and wet for me. Show me how pretty your mouth looks stretched around something thick.”
Chuuya moaned around the intrusion, his cheeks hollowing as he obeyed. He worked his tongue along the ridged surface, saliva slicking the toy, dripping from the corners of his mouth. The dual sensation—the fullness in his mouth, the aching emptiness between his legs—was maddening.
Dazai watched, his own cock already thickening again, rising against Chuuya’s lower back. “So fucking good for me,” he praised, his hand tangling in Chuuya’s auburn hair. “You look so perfect like this. My greedy omega. Can’t get enough, can you?”
Chuuya shook his head, the movement making him gag slightly around the toy. He loved this. Loved the way Dazai used him, the way he orchestrated every sensation, every debauched detail.
Dazai pulled the toy from his mouth with a soft, wet pop. Chuuya gasped for air, his lips feeling swollen. He didn’t have time to recover. Dazai shifted behind him, and Chuuya felt the slick, cool tip of the toy press against his already-stretched, dripping entrance.
“Dazai—” he started, but the name was cut off into a sharp cry as Dazai pushed the toy in.
It was a different kind of fullness. Unyielding, constant. It stretched him open again, filling the space Dazai’s knot had just vacated. Dazai worked it in slowly, watching with rapt attention as the black silicone disappeared inside Chuuya’s body. “Look at that,” he breathed. “Taking it so easy. You’re still so open for me. Fucking ruined.”
He pushed it all the way in, until the flared base rested snug against Chuuya’s skin. The pressure was intense, a constant, deep ache. Then Dazai’s hands were back on his hips, and Chuuya felt the hot, blunt head of Dazai’s cock nudging against him, right below the toy.
“Fuck, Dazai, you can’t—” Chuuya’s protest died in a strangled gasp as Dazai pushed.
He could. The toy inside him shifted, making room as Dazai’s thick cock began to press into him alongside it. The stretch was monstrous. It burned, it ached, it felt like he was being split in two. Chuuya screamed into the wood of the desk, his fingers scrabbling for purchase. He was so impossibly full, stuffed beyond belief, every nerve ending screaming.
“I can,” Dazai grunted, his voice strained with the effort of forcing his way in. “And you’re going to take it. You’re going to take all of me. Every. Last. Fucking. Inch.” He punctuated each word with a shallow, brutal thrust, sinking deeper each time.
Chuuya sobbed, tears of overwhelming sensation leaking from his eyes. It was too much. It was everything. The dual invasion lit up his brain, a feedback loop of pleasure and pain that had him shaking. Dazai finally bottomed out, his balls pressed against Chuuya’s skin, his cock buried to the hilt alongside the toy. He held there, panting, letting Chuuya feel the complete, devastating fullness.
“How does it feel?” Dazai whispered, his voice wrecked. “Tell me how my cock feels inside you, Chuuya. Tell me how it feels to be this fucking full of me.”
“I—I can’t—” Chuuya choked out. “It’s so much. You’re so big, Dazai, you’re splitting me open. I feel you everywhere. I feel the toy. I can’t even think.” The words were a raw, honest torrent. “It’s the best thing I’ve ever fucking felt. Don’t stop. Please, fuck me with it. Fuck me until I break.”
Dazai groaned, a sound of pure, unfiltered lust, and began to move.
His thrusts were short, hard, and devastatingly deep. The toy shifted inside Chuuya with every movement, rubbing against his prostate from one angle while Dazai’s cock assaulted it from another. The pleasure was a constant, electric current, building and building with nowhere to go. Chuuya’s moans were high-pitched, desperate things. He was babbling, a stream of filth and praise. “Fuck, yes, right there, you’re hitting it, you’re hitting everything, oh god, Dazai, fuck me!”
Dazai’s rhythm became punishing, his hips a relentless piston. The sound was obscene—wet, slapping flesh, the squelch of the toy moving inside him, their mingled groans. Dazai leaned over him, his chest pressed to Chuuya’s back, his mouth against Chuuya’s ear. “You’re going to come again,” he snarled. “You’re going to come just from my cock fucking you like this. You’re going to scream for me.”
He was right. The coil in Chuuya’s gut, strained to its absolute limit, snapped. His orgasm tore through him with a violence that stole his vision. His body clamped down, a vicious, rhythmic squeeze around the two intrusions filling him. Another hot, clear gush of fluid erupted from him, soaking the desk beneath them, dripping down his legs. He screamed, a raw, broken sound that echoed off the walls.
Dazai fucked him through it, his own control shattering. His thrusts became frantic, his breathing ragged. “Chuuya—fuck—I’m gonna fill you up again,” he growled. “I’m gonna pump you so full of my cum it’ll never stop leaking out of you. You want that? You want me to come inside you again?”
“Yes! Please, Dazai, come in me!” Chuuya begged, mindless, his oversensitive body convulsing with aftershocks. “Fill me up, alpha, I need it, I need your fucking cum, breed me, please!”
With a final, shuddering roar, Dazai slammed home and emptied himself. Chuuya could feel the hot, liquid pulse of it deep inside, another flood joining the first. It felt endless, a claiming so profound it felt like a brand. Dazai collapsed over him, his weight a crushing, perfect anchor. He turned Chuuya’s head and captured his lips in a deep, claiming kiss, swallowing Chuuya’s exhausted moans.
