The door clicked shut behind them, the lock engaging with a soft metallic sound that seemed to seal off the rest of the world. The room smelled of stale air-conditioning and spilled champagne, but the blue glow of the digital clock and the distant sparkle of the Eiffel Tower through the window softened the sterile edges. Katsuki didn't let go of Izuku's hand, his thumb tracing a slow, deliberate circle over the freckled knuckles.
"We're really here," Izuku whispered, his voice carrying the weight of the evening's confessions. His eyes found the faint lights of the city beyond the glass, then slid back to Katsuki's face. "Just us."
"Just us." Katsuki echoed it, then tugged him closer. His free hand came up to cup Izuku's jaw, tilting his face gently. "No more running. No more pretending."
They kissed slowly, a deepening press of lips that didn't rush. Katsuki's lips parted first, inviting, and Izuku leaned into him, letting the world dissolve into the wet slide of mouths and the soft, hitching breaths between kisses. Katsuki's palm slid from jaw to the back of Izuku's neck, fingers threading into the green curls, holding him there like something precious.
When they broke for air, Izuku's hands found the lapels of Katsuki's jacket. "Help me take this off," he murmured, and there was no hurry in the request, only the pleasure of being undressed by someone who knew exactly how to unwrap a gift.
Katsuki worked the buttons of his own shirt with deliberate care, his eyes never leaving Izuku's. The fabric slid from his shoulders, revealing the hard planes of his chest, the faint sheen of sweat over his collarbones. Izuku's gaze traced the line of his throat, the dip between his pectorals, and he wet his lips without thinking. "You're beautiful," he breathed.
"Shut up," Katsuki said, but his voice was rough and his hands were already reaching for the hem of Izuku's dress shirt. They undressed each other piece by piece, each garment falling to the floor like a promise shed. The cool air kissed Izuku's exposed skin, his top surgery scars catching the blue light from the clock, and Katsuki paused to trace one of them with a fingertip, featherlight. "This is you," he said. "Every part."
When they were both naked, the city lights painting their bodies in soft gold and blue, Katsuki stepped back just enough to look. Izuku stood before him, unashamed, his pussy already slick with need, his clit hard and glistening. Katsuki's own cock stood thick and heavy between his thighs, the head glistening with precum. "I'm going to take my time," Katsuki said, his voice dropping to a low, steady register. "I'm going to make you feel everything."
"Yes," Izuku breathed, and it was surrender and invitation together. He reached for Katsuki's hand, guiding it to his chest, letting Katsuki's palm press against his heart. "Feel that? That's yours. Always has been."
Katsuki's mouth found his again, softer now, almost reverent, as he backed Izuku toward the bed. The duvet crumpled beneath them, and the Eiffel Tower blinked once, twice, through the window, like a distant witness to a promise made flesh.
Katsuki broke the kiss slowly, his lips trailing down the corner of Izuku's mouth, along the sharp line of his jaw, tasting the salt of tears he hadn't noticed Izuku had shed. His mouth found the pulse point beneath Izuku's ear, and he paused there, feeling the frantic rhythm against his tongue. "I've got you," he murmured, the words vibrating against the sensitive skin. "Let me have you. All of you."
He moved lower, kissing the column of Izuku's throat, laving at the hollow where his collarbones met. Izuku's hands found Katsuki's shoulders, gripping them like anchors as the blonde's lips traced a path down his sternum. Katsuki's mouth was deliberate, unhurried, pressing reverent kisses to every inch of skin he uncovered. When he reached the curve of Izuku's chest, his lips brushed over a dusky nipple, and Izuku gasped, his back arching off the mattress.
Katsuki didn't rush. He circled the nipple with his tongue, feeling it pebble against the wet heat, before trailing his mouth across the clean line of Izuku's top surgery scars. He felt Izuku tense beneath him, a tremor of vulnerability, and he pressed a soft, open-mouthed kiss to the scar tissue. "I love these," he breathed against the skin. His voice was rough, barely a whisper, but it carried the weight of absolute truth. "They're proof you fought for yourself. Proof you became who you were always supposed to be. Every fucking inch of you, Izuku."
Tears slipped freely from Izuku's eyes now, tracking down his temples into his green curls. His hands trembled as they threaded into Katsuki's ash-blond hair, cradling his head close. "Kacchan—" The name came out broken, a sob wrapped in a prayer. "I was so scared you'd... that anyone would..."
"Never." Katsuki lifted his head just enough to meet Izuku's eyes, his own crimson gaze fierce and wet. "I love your brain that never shuts up. I love your hands that wave around when you talk. I love the stupid way you mumble. I love your scars. I love your soft thighs and your pretty fucking cunt and the sound you make when you come. I love you. Every part. All of it." He kissed the center of Izuku's chest again, right over his heart. "This is my home. It always has been."
He continued his descent, his lips dragging down the soft plane of Izuku's stomach, tracing the dip of his navel. He nuzzled into the crease of Izuku's hip, tasting the salt of his skin, feeling the muscles quiver beneath his mouth. Izuku's breath came in ragged, hiccupping gasps, his hands fisting in the sheets as Katsuki pressed a wet kiss to the jut of his pelvis.
"Legs open, Izu," Katsuki whispered, his voice low and thick with devotion. "Let me see you." Izuku obeyed, his thighs falling apart, revealing the slick pink of his pussy, his clit swollen and glistening in the blue light. Katsuki let out a shuddering breath against his skin, his eyes fixed on the sight like it was the most beautiful thing he'd ever witnessed. "God, Izuku. You're so fucking wet for me."
He didn't dive in. He kissed Izuku's inner thigh, slow and deliberate, feeling the jump of his pulse against his lips. He kissed the other thigh, biting softly, soothing the sting with his tongue. Izuku whimpered, his hips bucking slightly, searching for contact. "Please, Kacchan, please—"
"Shh." Katsuki's hand pressed down on Izuku's hip, stilling him. "I told you. I'm gonna take my time." He pressed a kiss to the nest of green curls at the apex of Izuku's thighs, then finally, slowly, lowered his mouth to Izuku's cunt. His tongue was flat and broad, licking a wet, deliberate stripe from his entrance up to his clit, tasting him completely. Izuku cried out, a raw, broken sound, his body bowing off the bed.
Katsuki groaned against him, the vibration sending shocks through Izuku's entire system. He sucked the swollen clit into his mouth, his tongue flicking across it in a wet, relentless rhythm. His hands gripped Izuku's thighs, spreading him wider, holding him open like an offering. "Love this," he muttered against the wet heat, his voice muffled and wrecked. "Love the way you taste. The way you sound. The way you clench around nothing. All for me. Say it, Izuku. Tell me who you belong to."
"You," Izuku sobbed, tears streaming, his hands fisted in Katsuki's hair, holding him there. "I'm yours, Kacchan. Always have been. Always—" His words cut off as Katsuki's tongue pushed inside him, fucking him slow and deep, and the world dissolved into the wet sounds of Katsuki's mouth and the trembling surrender of Izuku's body beneath the blinking lights of Paris.
The pleasure coiled in Izuku's belly, winding tighter with every stroke of Katsuki's tongue. His hips rocked against that perfect mouth, chasing the heat, the pressure, the inevitable crest that would shatter him into a million pieces. "Kacchan," he gasped, his voice high and broken. "I'm close, I'm so close—" His fingers tightened in Katsuki's hair, a warning and a plea, but just as the wave began to crest, he pushed at Katsuki's shoulders. "Wait. Wait. Stop."
Katsuki pulled back immediately, his lips slick and swollen, his crimson eyes hazy with want. "What's wrong?" His voice was rough, urgent. "Did I hurt you?"
"No." Izuku shook his head, chest heaving, green curls plastered to his forehead. "No, you're perfect. But I don't want to cum like this. Not alone." He reached down, his hand finding Katsuki's jaw, tilting his face up so their eyes met in the dim blue light. "I want to come with you inside me. I want to feel you—all of you. I want us to fall apart together."
Katsuki's breath hitched. He leaned up, kissing Izuku hard and deep. "Yeah," he breathed against his mouth. "Yeah, I want that too." He shifted, his weight pressing Izuku into the mattress, his cock sliding through the slickness of Izuku's folds, wet and heavy. He reached for the nightstand, fingers fumbling for the condoms he'd bought that morning, the crinkle of the wrapper loud in the quiet room.
Izuku's hand caught his wrist, gentle but firm. "Kacchan." He shook his head slowly, his eyes steady. "No condom."
Katsuki froze, the wrapper halfway torn. "Deku—"
"I want a family with you." Izuku's voice was soft, trembling, but certain. "Someday. I want to wake up next to you every morning, fight with you, make up with you. I want to grow old with you. And if tonight gives us a baby..." He smiled, tears spilling down his temples. "That's just a bonus. A gift from tonight. I want this. I want all of it."
Katsuki's heart slammed against his ribs. The wrapper fell from his fingers, forgotten. He stared down at Izuku—freckled, tear-streaked, vulnerable, brave—and something cracked open in his chest. Kids. With Izuku. Izuku pregnant with his child, round and glowing and his. He'd never let himself want that, never even thought it was possible, but now the image flooded him, hot and desperate and impossibly right. "Fuck," he whispered, his voice wrecked. "Fuck, Izu. I want that too. I want to get you pregnant. I want to see you carrying our baby. I want everything."
He lowered himself, his forehead pressing against Izuku's, their breath mingling in the charged space between them. "You sure?" he asked, needing to hear it one more time.
"I've never been more sure of anything." Izuku's hand slid down Katsuki's chest, over his stomach, until his fingers wrapped around the base of his cock, guiding it to where he needed it most. "Make love to me, Kacchan. Take me home."
Katsuki pushed forward, the head of his cock pressing against Izuku's slick entrance. He went slow, deliberate, watching Izuku's face as the stretch began—the flutter of his eyelids, the parted lips, the soft, broken moan. Inch by inch, he sank into that wet heat, no barrier between them, nothing but skin and trust and a future neither of them had dared to name until now. When he was fully sheathed, buried to the hilt, he paused, letting Izuku adjust, letting the moment hang between them—two bodies, one promise, the distant lights of Paris blinking like stars through the window.
"I love you," Katsuki breathed, his hips beginning to move, slow and deep. "God, I love you so much it hurts."
Izuku's breath stuttered as Katsuki's words sank into him, deeper than any penetration, settling into the marrow of his bones. His hands cupped Katsuki's jaw, thumbs brushing the sharp cheekbones, smearing tears he hadn't realized were still falling. "I love you too, Kacchan," he whispered, the words rising from somewhere primal, from the four-year-old who'd first seen a boy with a sunburst smile and a temper like a lit fuse. "I've loved you my whole life. I think I was born loving you. It's the only thing that's ever made sense." His voice cracked, but he didn't stop. "You're my first thought in the morning and my last thought at night. You're the reason I breathe. I love you more than anything in this world. More than life itself."
Katsuki's hips faltered, a shudder running through his entire frame. "Fuck, Izu—" His voice broke, and he pressed his forehead hard against Izuku's, their breath mingling in the charged space between them. "Say it again."
"I love you." Izuku's lips brushed against Katsuki's as he spoke, the words a prayer and a promise. "I love you, I love you, I love you—"
Katsuki kissed him then, deep and desperate, swallowing the confessions like they were oxygen. His tongue swept into Izuku's mouth, tasting salt and need and the future they'd just promised each other. His hips found a rhythm again—slow, grinding, deliberate—each thrust a declaration. Izuku's legs wrapped around his waist, pulling him deeper, and the kiss broke into gasps as the pleasure coiled tighter in both their bellies.
"I can feel you," Katsuki breathed against his lips, his voice wrecked. "Every inch of you. Just us." His hand slid between them, thumb finding Izuku's clit, pressing firm circles in time with his thrusts. "You're gonna cum with me, Izu. We're gonna fall apart together. And then we're gonna do it again tomorrow. And the day after. And every goddamn day for the rest of our lives."
Izuku's response was lost in a moan as Katsuki's thumb pressed harder, the friction sending sparks up his spine. His inner walls clenched around the thick length inside him, feeling every ridge, every pulse of Katsuki's cock as it slid through his slick heat. "Kacchan—I'm—" His hips bucked, chasing the edge. "I'm so close—"
"Me too." Katsuki's forehead was damp, his jaw tight, his eyes locked on Izuku's with a ferocity that bordered on worship. "Look at me, Izu. I want to see your eyes when you cum. I want to watch you fall apart knowing I put you there."
Izuku's green eyes held Katsuki's red ones, the world narrowing to that single point of connection. The pleasure built in waves—each thrust, each circle of Katsuki's thumb, each ragged breath—and he felt himself rising, the crest impossibly close. "Don't stop," he gasped, his nails digging into Katsuki's shoulders. "Please don't stop—"
"Never," Katsuki swore, and he drove deeper, harder, his own release coiling in his groin like a spring wound too tight. "Cum for me, Izu. Let go. I've got you."
Izuku's mouth found Katsuki's again as the wave crested, the kiss swallowing the broken cry as his body arched, his cunt clenching around Katsuki's cock in a rhythmic, pulsing surrender. He felt the answering shudder in Katsuki's frame, the guttural groan against his lips as Katsuki spilled into him, hot and thick and endless, the sensation of being filled painting the world in white light. They held each other through the tremors, lips still pressed together, breathing each other's air, the Eiffel Tower blinking through the window like a promise being kept.
They lay tangled together, the aftershocks still rippling through their bodies in small, involuntary shivers. Izuku's face was pressed into the curve of Katsuki's neck, his breath hot and uneven against the sweat-sheened skin. He could feel Katsuki's heart hammering against his own chest, a wild, desperate rhythm slowly decelerating into something steadier. "I love you," Izuku whispered against his pulse, the words muffled but clear. "I love you, Kacchan."
Katsuki's arms tightened around him, one hand sliding up to cradle the back of Izuku's head, fingers threading through the damp green curls. "I love you too," he breathed, his voice rough and spent. "Fuck, Izu. I love you so much it scares me." He pressed a kiss to the top of Izuku's head, lingering, breathing him in. "You're everything. Everything."
Slowly, reluctantly, Katsuki eased out of him, the loss of connection making Izuku whimper softly. "Shh," Katsuki murmured, already reaching for the discarded shirt on the floor to clean them both up. He was gentle, reverent, dabbing at the mess between Izuku's thighs before tossing the shirt aside. Then he pulled Izuku close, turning them onto their sides so Izuku's back was pressed against his chest, his arm wrapping around Izuku's waist, hand splayed flat over his stomach.
Izuku's hand found Katsuki's, their fingers intertwining. He felt the warmth of Katsuki's body against his, the steady thrum of his heartbeat through his back. "I can feel you," Izuku whispered, a sleepy smile tugging at his lips. "Still inside me. In a way." He laughed softly, a breathless, contented sound. "I like it. I want to feel you for days."
Katsuki's thumb traced lazy circles on Izuku's stomach, his lips brushing against the shell of his ear. "Good," he said, his voice a low rumble. "Because I'm not letting you go. Ever. You're stuck with me, Deku." The old nickname carried no sting now—only affection, only history, only the weight of twenty years of love finally spoken aloud. "You and me. Against the world."
"Against the world," Izuku repeated, his voice already growing heavy with sleep. He curled deeper into Katsuki's arms, his legs tangling with Katsuki's. "I'm so tired, Kacchan. But I don't want to sleep. I don't want to miss a second of this." He tilted his head back, his green eyes finding Katsuki's red ones in the dim light. "What if I wake up and it's all a dream?"
Katsuki's hand slid up from Izuku's stomach to his chest, pressing flat over his heart. "Feel that?" he asked, his voice fierce and tender. "That's my heart beating. It's been yours since I was four years old. This isn't a dream, Izu. This is real. This is us." He kissed the corner of Izuku's mouth, soft and lingering. "I'm not going anywhere. I'll be here when you wake up. I'll be here every morning for the rest of our lives."
Izuku's eyes fluttered closed, a single tear escaping down his cheek. "Promise?" It came out small, vulnerable, the question of a boy who'd spent years believing he'd never be loved back.
"I promise." Katsuki's voice cracked, but he held steady. "I promise, I promise, I promise." He pressed another kiss to Izuku's temple, then to his closed eyelid, tasting the salt of his tears. "Sleep, Izu. I've got you. I'll keep you safe."
The exhaustion settled over them like a heavy blanket, the emotional weight of the day—the confessions, the confrontations, the love finally spoken and received—pulling them both under. Izuku's breathing evened out first, his body going slack and boneless against Katsuki's. Katsuki held him through it, his hand never stopping its gentle rhythm on Izuku's stomach, his own eyes growing heavy as he watched the Eiffel Tower blink its silent Morse code through the window.
"Love you," Katsuki whispered one last time into the darkness, his lips against Izuku's hair. He felt Izuku's hand tighten around his in sleep, a reflex that said even unconscious, he was holding on. Katsuki smiled, a soft, private thing no one would ever see, and let his own eyes close. For the first time in years, his mind was quiet. No what-ifs. No regrets. Just the warmth of the man in his arms and the slow, steady rhythm of two hearts beating together in the Paris night. He was home. He'd always been home. He just hadn't known it until now.
The morning light crept through the gap in the curtains, pale gold and soft, painting a stripe across the rumpled sheets. Izuku stirred first, his consciousness rising slowly through layers of warmth and satisfaction. The first thing he registered was the weight of an arm around his waist, the solid heat of a chest against his back, the slow, steady rhythm of breath stirring his curls. For a moment he held perfectly still, afraid to break the spell, to prove it had all been a dream. But Katsuki's arm tightened reflexively, pulling him closer, and a low, sleep-rough murmur vibrated against his spine. "Mornin', Izu."
Izuku's heart swelled so full it ached. He turned slowly, carefully, until he was facing Katsuki—those sharp cheekbones softened by sleep, those crimson eyes heavy-lidded and warm, that impossible ash-blond hair a riot against the pillow. "Good morning," Izuku whispered, his voice cracked and tender. He reached up, tracing the line of Katsuki's jaw with reverent fingers. "You're here. You're really here."
"Where else would I be?" Katsuki's voice was gravel, sleep and emotion tangling into something raw. He caught Izuku's hand, turning it to press a kiss to the palm, his lips lingering. "Told you I'd be here when you woke up. Told you I'd be here every morning." His eyes met Izuku's, fierce and soft at once. "I love you, Izu. That wasn't a dream. That was real. This is real."
Izuku's breath hitched, the words hitting him like a wave, washing away the last clinging doubt. "I love you too, Kacchan," he breathed, and the name carried twenty years of history, of longing, of finally. "I love you so much. I spent so long thinking I'd never get to say that to you. That I'd never get to wake up like this." He laughed, a wet, broken sound. "But here you are."
"Here I am." Katsuki's hand slid from Izuku's palm to cup his cheek, thumb brushing the constellation of freckles beneath his eye. "And I'm not goin' anywhere. You're stuck with me, Deku. Forever." He said the old name like a benediction, like a claim, and then he closed the distance between them.
The kiss was slow, deliberate, nothing like the desperate devouring of the night before. This was morning light and quiet certainty. Katsuki's lips moved against Izuku's with a tenderness that made Izuku's chest ache, tasting of sleep and the faint salt of dried tears. Izuku's fingers found their way into Katsuki's hair, threading through the spikes, pulling him closer. The kiss deepened, tongues brushing, a shared sigh escaping into the space between breaths.
"I could do this forever," Izuku murmured against Katsuki's lips, his voice a low, contented hum. "Just wake up and kiss you. Every day. For the rest of my life." He pulled back just enough to meet Katsuki's eyes, his own green ones bright with unshed tears. "Is that too much to ask? Is that—"
"No." Katsuki cut him off with another kiss, firmer this time, a little insistent. "That's not too much. That's exactly what we're gonna do." He pulled back, his hand sliding from Izuku's cheek to rest over his heart, feeling the steady thump beneath his palm. "I've been waiting my whole life for this, Izu. I'm not gonna waste a single second of it."
Izuku's smile broke across his face like sunrise, bright and unguarded and utterly, devastatingly happy. He stretched up, pressing a soft, lingering kiss to the corner of Katsuki's mouth. "Then let's not waste it," he whispered. He shifted, curling closer, his leg sliding between Katsuki's, his face finding its home in the curve of Katsuki's neck. "Stay here with me. Just a little longer. The whole world can wait."
Katsuki's arms wrapped around him, one hand settling on the small of his back, the other cradling the back of his head. He pressed a kiss to Izuku's hair, breathing in the scent of him—sweat and sleep and something indefinably Izuku. "The whole world can wait," he agreed, his voice a low rumble against Izuku's scalp. "I've got everything I need right here." He felt Izuku smile against his skin, felt the tension drain from his body as he melted into the embrace, and let his own eyes drift closed. The morning stretched around them, golden and still, and for a long, perfect moment, nothing else existed. Just them. Just this. Just the beginning of forever.
