Collision

Summary:

He turned.

A body collided with his.

Liquid splashed. Glass shattered. Shidou’s half-empty drink cascaded down the front of someone’s dark shirt, soaking the fabric in sticky amber.

“Fuck—shit, sorry,” Shidou blurted, reaching out instinctively to steady the person he’d crashed into.

His hand caught an arm. Slender, but firm. Warm.

And then he looked up.

Work Text:

The bass thrummed through Shidou’s ribs like a second heartbeat. Lights strobing red, blue, white—disorienting flashes that turned the crowd into a sea of shifting shadows. He’d come here to blow off steam after a shitty week, not expecting anything more than cheap beer and louder music.

He turned.

A body collided with his.

Liquid splashed. Glass shattered. Shidou’s half-empty drink cascaded down the front of someone’s dark shirt, soaking the fabric in sticky amber.

“Fuck—shit, sorry,” Shidou blurted, reaching out instinctively to steady the person he’d crashed into.

His hand caught an arm. Slender, but firm. Warm.

And then he looked up.

The most beautiful person he’d ever seen stared back at him. Turquoise eyes, sharp as cut glass, framed by strands of a reddish-burgundy hair that fell messily across a pale forehead. Lips slightly parted in surprise. A face that belonged in a museum, not a sweaty nightclub.

Shidou’s brain short-circuited.

“Watch where you’re going,” the guy said, but his voice lacked any real bite. Quiet. Measured. Like he was assessing a situation rather than reacting to it.

“I—” Shidou swallowed. His usual sarcastic retorts evaporated. “Let me buy you a drink. To replace the one I just sacrificed to your shirt.”

A pause. Those turquoise eyes studied him with unsettling precision.

“You’re not going to grovel?”

“Would that help?”

The corner of the guy’s mouth twitched. Barely. But Shidou caught it.

“Sae,” he said, extending a hand. “Itoshi Sae.”

Shidou took it. Held it maybe a second longer than necessary. “Shidou Ryusei.”

Sae’s fingers were cool against his palm. The grip was brief but deliberate.

They ended up in a corner booth, far from the speakers, where the music became background hum instead of assault. Shidou flagged down a waitress, ordered two whiskeys, and immediately forgot they existed.

“So what’s someone like you doing in a place like this?” Shidou asked, leaning forward with his elbows on the sticky table.

“Someone like me?”

“You know. Pretty. Put-together. Looks like you’d rather be at a gallery opening or whatever rich people do.”

Sae raised an eyebrow. “And what does that make you?”

“Loud. Obvious. The guy your mother warned you about.”

“My mother doesn’t warn me about anything. She knows I can handle myself.”

God, that voice. Low. Calm. Each word placed with precision, like Sae was choosing them carefully from a curated collection. There was no nervous energy, no filler. Just quiet confidence.

Shidou was hooked.

The whiskey arrived. They drank. They talked. Hours dissolved.

Sae worked in finance—something about international investments. He traveled constantly. He’d been to nineteen countries and said the only thing consistent about them was bad coffee and worse customer service. He played chess. He read philosophy. He had a dry sense of humor that caught Shidou off guard every single time.

“You’re staring,” Sae said at one point, mid-sip.

“Yeah. So?”

“Most people look away when I catch them.”

“I’m not most people.”

Sae set his glass down. “No. You’re not.”

The way he said it—flat, observational, like he was noting a fact about the weather—sent heat crawling up Shidou’s neck.

More small drinks of alcohol came. The world softened at the edges. Shidou lost count after four, maybe five. The bass still thumped, but it felt distant now, muffled, like hearing music through water.

“Wanna—” Shidou paused, his tongue thick in his mouth. “W-wanna come to mmmyy.. house Sae?”

The words slurred together. He knew they did. Couldn’t find the coordination to fix them.

Sae’s eyebrow lifted again. That same assessing look.

“You’re drunk.”

“M’fine.”

“You’re barely standing.”

“M’perfect.” Shidou grinned, lopsided and unsteady. “C’mon. Just for a bit. Promise I’ll behave.”

“I doubt that.”

But Sae stood. Reached out a hand. Helped Shidou navigate through the crowd and out into the cool night air.

The taxi ride was a blur of streetlights and muffled radio. Shidou pressed his forehead against the window, letting the glass cool his flushed skin. Sae sat beside him, close enough that their shoulders brushed with every turn.

Shidou focused on that contact. The warmth. The solidity.

Sae paid the driver. Helped Shidou out of the cab. Guided him up the walkway to the front door.

“Keys,” Sae said.

Shidou fumbled in his pocket. Dropped them twice. Sae sighed, bent down, and picked them up, unlocking the door with practiced efficiency.

The hallway was dark. Quiet.

Shidou’s blood was buzzing.

He moved before his brain caught up. Turned. Pinned Sae against the wall, hands gripping narrow shoulders, breathing hard.

Sae’s eyes widened. Just a fraction. Just enough.

“You—” Sae started.

Shidou kissed him.

Hard. Messy. Hungry.

Sae’s response was immediate—lips parting, hands coming up to grip Shidou’s shirt, pulling him closer instead of pushing him away.

Yes. Fuck yes.

Shidou broke the kiss, chest heaving. “Bedroom. Upstairs.”

“You can barely walk.”

“Don’t need to walk.” Shidou bent, hooked an arm under Sae’s knees, and lifted.

Sae let out a sound—half gasp, half laugh—as Shidou carried him up the stairs, each step deliberate despite the alcohol fogging his coordination.

“You’re insane,” Sae murmured against his neck.

“Yeah. Heard that before.”

The bedroom door was already open. Shidou crossed to the bed and dropped Sae onto the mattress. Watched him bounce once, twice, then settle, teal hair fanning across the dark sheets.

Beautiful. So fucking beautiful.

Shidou climbed onto the bed, straddling Sae’s hips, looking down at him. The overhead light caught the angles of Sae’s face—sharp cheekbones, defined jaw, those turquoise eyes now dark with something Shidou recognized.

Want.

Shidou reached out. Traced his fingers through Sae’s hair, the strands silky against his calloused skin.

“You have no idea,” Shidou said, voice low, “what you do to me.”

“Show me.”

Those two words. Quiet. Challenging. A dare.

Shidou’s chest tightened.

He grabbed the hem of Sae’s shirt—the one he’d ruined earlier, still damp in patches—and pulled it up. Sae lifted his arms, let it slide off, let it fall somewhere on the floor.

Shidou’s breath caught.

Sae’s upper body was lean. Defined. Pale skin stretched over a flat stomach, a narrow waist, shoulders that spoke of quiet strength. A thin line of hair trailed from his navel downward, disappearing beneath his waistband.

“Fuck,” Shidou breathed.

He leaned down, pressed his lips to Sae’s collarbone. Trailed kisses down the center of his chest, tasting salt and something sweeter underneath. Sae’s hand came up, fingers threading through Shidou’s hair, gripping.

Shidou worked his way lower. Teeth grazing a nipple. Tongue soothing the sting. Sae’s breath hitched—a sharp inhale, a whispered “Ah—”

“Sensitive?” Shidou murmured against his skin.

“Shut up.”

Shidou grinned. Continued downward.

His hands found Sae’s waistband. Unbuttoned. Unzipped. Pulled pants and boxers down together, sliding them past narrow hips, past slender thighs.

And then Shidou saw it.

He froze.

Sae’s cunt. Pink. Soft. The outer lips slightly parted, glistening with the beginnings of wetness. A dusting of dark hair above, neatly trimmed.

Sae gasped, hands flying down to cover himself. “Wait—I—”

Shidou grabbed his wrists. Pinned them to the mattress.

“Don’t,” he said, voice rough. “Don’t hide from me.”

Sae’s face flushed. A deep red that spread down his neck, across his chest. He looked away, jaw tight.

“You’re perfect,” Shidou said. “Every part of you. Perfect.”

Sae’s throat worked. He didn’t speak.

Shidou released his wrists. Trailed a hand down Sae’s stomach, through that line of hair, until his fingers brushed the soft skin of Sae’s inner thigh.

“Let me taste you.”

Sae’s eyes snapped back to his. Wide. Vulnerable.

“Please,” Shidou added. And meant it. “I need to. I need you.”

A long moment. Turquoise searching crimson.

Then Sae nodded. Once. Barely.

Shidou didn’t wait.

He dove.

His mouth found Sae’s cunt like a man starved. Lips pressing, parting, tongue sliding between those plush outer lips to find the heat beneath. Sae gasped—a sharp, broken sound—and arched off the bed.

Shidou groaned against him. The taste was electric. Salt and musk and something uniquely Sae that made his head spin. He licked deeper, dragging his tongue through the slick folds, circling the tight bundle of nerves at the top.

“Ohhhh—fuck—”

Sae’s hands found his hair again. Pulled. Hard.

Shidou doubled down.

He sucked Sae’s clit into his mouth, flicking his tongue against it in rapid strokes. The sounds Sae made—high and breathy and desperate—fueled him. Pushed him further. Faster.

Wetter.

Shidou’s jaw worked, lips sealing around that sensitive nub as he sucked and licked and devoured. Sae’s hips bucked against his face, chasing the contact, and Shidou held him down with an arm across his stomach, keeping him in place.

“Mmnnph—Shidou—I can’t—it’s too—”

“More,” Shidou growled against his cunt. “Give me more.”

He pulled back just enough to slide two fingers through the mess he’d made. One found Sae’s entrance, slick and hot. The other pressed against the hood of his clit, applying pressure in small, deliberate circles.

Sae’s back bowed. A cry tore from his throat—loud, unfiltered.

“HHNNG—fuck—right there—”

Shidou pushed his finger inside. One knuckle. Two. Sae’s walls clenched around him, gripping, pulling him deeper.

“Yeah,” Shidou breathed against his thigh. “That’s it. Squeeze my fucking finger, Sae.”

He pumped. Slow at first, then faster. His tongue returned to Sae’s clit, lashing against it in time with his thrusts. The combination was devastating—Sae’s hips rocking, his breath coming in ragged gasps, his voice cracking on every moan.

“Ohhh—oh fuck—I’m gonna—Shidou I’m gonna—”

“Cum for me,” Shidou said, mouth pressed to that slick heat. “Cum on my face, Sae. Let me taste it.”

Sae screamed.

His body convulsed, thighs clamping around Shidou’s head as waves of pleasure tore through him. Shidou kept licking, kept pumping, drawing it out until Sae’s cries faded to whimpers and his legs went limp.

Shidou pulled back. Licked his lips. Smiled.

“Delicious.”

Sae was a mess. Eyes glazed, chest heaving, sweat glistening on his skin. His cunt was swollen, puffy, dripping with evidence of his release.

Shidou didn’t give him time to recover.

He crawled up Sae’s body, capturing his mouth in a kiss. Sae tasted himself on Shidou’s tongue—sharp and salty—and moaned into the kiss rather than pulling away.

“I’m not done with you,” Shidou murmured against his lips.

Sae’s eyes fluttered open. “Good.”

Shidou sat back. His cock strained against his jeans, painfully hard, the bulge obvious. He unbuckled his belt with rough, impatient movements, shoving his pants and boxers down his thighs.

His cock sprung free. Thick. Veined. The head flushed dark red, beading with precum.

“See what you do to me?” Shidou said, wrapping a hand around his shaft. “See how hard you make me?”

Sae’s gaze dropped. His lips parted.

Shidou reached down, grabbed Sae’s hip, and flipped him onto his stomach.

Sae’s ass was pale. Round. Perfectly shaped.

Shidou squeezed. Hard. Fingers digging into the flesh, watching it yield under his grip.

“Gonna fuck you now,” he said, voice low. “Gonna bury myself so deep in your ass you’ll feel me tomorrow.”

Sae’s breath hitched. “Just—do it already. I don’t give a fuck what you do.”

Shidou’s grin widened.

He brought his fingers to his mouth, sucked them wet, then reached down. Traced the ring of Sae’s entrance. Felt it tighten at the touch.

“Ready?”

“Shut up and fuck me.”

Shidou positioned himself. Rubbed the head of his cock against that tight opening, back and forth, letting the tip catch and slip, teasing.

“Fucking brat,” he muttered. “Taking what you want.”

Sae groaned. “Shidou—”

He pushed in.

The resistance was immediate—Sae’s ass clamping down like a vice, impossibly tight around Shidou’s girth. Sae cried out, a sharp “Fuck!” muffled against the mattress.

“Yeah,” Shidou hissed, gripping Sae’s hips. “Feels good, doesn’t it? Being stretched open.”

“Shut—hnng—shut up—”

Shidou pushed deeper. Inch by inch. Sae’s body fought him, then yielded, muscles slowly relaxing to accommodate his size.

“God, you’re tight,” Shidou growled. “Feels like you’re gonna break my fucking cock.”

Sae’s hands fisted in the sheets. His breath came in ragged gasps.

When Shidou was fully seated—balls deep in Sae’s heat—he paused. Let them both adjust. The sensation was overwhelming. Sae’s internal walls gripping him, pulsing around him, hot and tight and so fucking good.

Then he moved.

Slow at first. Shallow. Letting Sae get used to the rhythm.

But patience had never been Shidou’s strength.

He sped up. Harder. Deeper. Each thrust driving his cock to the hilt, the sound of skin slapping against skin filling the room.

Sae’s moans grew louder. More disjointed.

“Ahh—ohhh—fuck—Shidou—fuck me—fuck me harder—”

Shidou grabbed a handful of Sae’s hair. Pulled his head back, arching his spine. The new angle let him drill deeper, hitting spots that made Sae’s voice crack.

“You like that?” Shidou grunted, pounding into him. “You like being stuffed full of my cock?”

“YES—fuck—YES—”

“Tell me.”

“I fucking—ahh—LOVE IT—please—more—harder—”

Shidou released his hair. Grabbed both hips instead, fingers bruising, and rammed into him.

The bed creaked. Squealed. Protested.

Shidou didn’t care.

He fucked Sae with brutal, relentless strokes, each one driving them both higher. Sweat dripped down Shidou’s forehead, splashing onto Sae’s back. The room smelled like sex—sweat and saliva and arousal.

“I’m gonna fill you up,” Shidou growled. “Gonna pump my cum so deep in your ass you’ll feel it for days.”

Sae’s response was a broken, desperate moan.

Shidou’s balls tightened. The pressure coiling in his gut, building, building—

“Fuck—Sae—I’m—”

“Cum in me,” Sae gasped. “Cum in my fucking ass, Shidou—please—I want to feel it—want to feel you—”

Shidou’s hips slammed forward one last time. He buried himself to the hilt and came, ropes of hot cum flooding Sae’s insides. His vision went white. His entire body locked up, every muscle straining as he emptied himself into that tight, perfect heat.

Sae’s body convulsed beneath him. Another orgasm ripping through him, triggered by the feeling of Shidou filling him.

They stayed like that. Connected. Breathing hard.

Shidou pulled out slowly, watching his cum leak from Sae’s stretched hole. The sight made his cock twitch despite the exhaustion.

He collapsed onto the bed beside Sae. Pulled him close, ignoring the mess, pressing a kiss to his sweat-soaked temple.

“That was—”

“Incredible,” Sae finished, voice hoarse.

Shidou laughed. “Yeah. Incredible.”

Sae turned in his arms. Those turquoise eyes met his. Soft now. Vulnerable.

“I didn’t expect this,” Sae said quietly.

“Me neither. But I’m not complaining.”

Sae’s lips curved. That tiny smile again.

“Can I stay?”

Shidou’s heart lurched.

“Yeah,” he said, pulling Sae tighter. “Yeah. Stay.”
