The city glittered far below them, a basin of cold light, but up on the penthouse balcony the air was warm and smelled of expensive whiskey and night-blooming jasmine. Katsuki stood by the railing, a glass in his hand, his sharp red eyes fixed on Izuku.

Izuku stood in the center of the balcony, bathed in the soft glow of string lights. The “dress” was white lace that dissolved into sheer mesh, cutting high on his thighs and plunging low over the small, soft curves of his chest. A short veil was pinned in his messy green curls. He held a single, trembling white orchid. “Daddy?”

“Look at you,” Katsuki’s voice was a low, graveled rumble. He set his glass down and walked over, the callused pad of his thumb tracing the lace edge over Izuku’s nipple. “My little bride.”

“You really did this,” Izuku whispered, his wide green eyes shining. “For me.”

“For us.” Katsuki’s hand slid down, palming the curve of Izuku’s ass through the fragile lace. “You said you wanted to be my wife. So we’re having a fuckin’ wedding.”

The balcony door slid open. Eijiro Kirishima stepped out, his spiky red hair bright under the lights, a wide, easy grin on his face. Behind him, Tetsutetsu followed, his silver hair fluffy, his black eyes taking in the scene with a grunt of acknowledgment.

“You guys clean up nice!” Eijiro boomed, pulling his son along. “Tetsu, look. It’s a party.”

“I see it,” Tetsutetsu muttered, his gaze lingering on the sheer fabric clinging to Izuku’s thighs.

Katsuki didn’t remove his hand from Izuku’s ass. “You’re the witnesses. And the officiant, shitty hair.”

Eijiro’s grin softened into something more genuine. “I’m honored, man. Seriously.” He clapped his hands together. “Alright! Let’s get this show on the road. You got vows?”

Izuku’s breath hitched. He looked up at Katsuki, the city lights reflecting in his eyes. “I do.”

Katsuki nodded, a silent command.

Izuku’s voice trembled, but it carried. “Daddy… Katsuki. You’re my whole world. Even when it hurt. Especially when it hurt. You made me. You own me. I don’t want to be anything but yours. I vow to be your good boy. Your cunny boy. Your… wife. Forever.” A tear traced through the freckles on his cheek.

Katsuki’s jaw tightened. His crimson eyes burned. He cupped Izuku’s face, his thumb smearing the tear. “Izuku. My boy. My secret. My sin.” He leaned down, his breath warm and smelling of whiskey. “You’re mine. You take my cock, you take my cruelty, you take my fucked-up love. And now you’ll take my name, officially. I vow to keep you. To breed you. To make sure everyone knows who you belong to. You’re my wife. My pregnant, barefoot, little boy wife.”

Eijiro sniffled, wiping at his eye. “Manly. So manly. Okay! By the power vested in me by… this really nice balcony… I now pronounce you husband and wife. You may kiss your… um, groom. Bride. Groom-bride.”

Katsuki didn’t wait. His hand fisted in the lace at Izuku’s back and yanked him flush. His mouth crashed down on Izuku’s.

It wasn’t a kiss. It was a claiming. Hot, open-mouthed, and filthy. Katsuki licked into him, tasting the champagne Izuku had sipped earlier, and Izuku melted, a whimpering sigh swallowed whole. His hands came up to clutch at Katsuki’s shoulders, the orchid dropping to the floor.

Katsuki bit his bottom lip, sucked it, then plunged his tongue back in, deeper. Izuku could feel the hard line of Katsuki’s cock straining against his slacks, pressing into his belly. He moaned, arching into it, the sheer lace doing nothing to hide his own hardening nipples or the sudden, slick heat between his thighs.

Katsuki’s other hand slid down, over the lace-covered ass, and shoved the flimsy material aside. His rough fingers dug into bare, soft flesh. He ground his hips forward, making Izuku gasp into the kiss.

When he finally pulled back, a string of saliva connected their mouths. Izuku’s lips were swollen, wet, and his eyes were glazed. “Daddy,” he panted.

“Wife,” Katsuki growled, his voice dark and thick. His gaze never left Izuku’s as his fingers, now slick from the heat they’d found, traced lower, through the wet folds he’d exposed. “Already dripping for me. On our wedding night.”

"On your knees, wife," Katsuki growled, his hand still buried between Izuku's thighs. He withdrew his slick fingers and pressed them against Izuku's swollen lips. "Show our guests how you worship your husband."

Izuku didn't hesitate. He sank to the warm balcony tiles, the lace of his outfit tearing faintly at the knees. His green eyes, wide and dark, stayed locked on Katsuki’s as his father undid his slacks, freeing his thick, uncut cock. It was already fully hard, flushed and heavy, the head glistening.

"Look at that," Eijiro breathed, his arm sliding around Tetsutetsu’s waist. "So manly."

Izuku leaned forward, his lips parting. He didn't just take the head; he engulfed it, his mouth stretching wide, a low, hungry sound vibrating in his throat. He sucked hard, his cheeks hollowing, his tongue working the sensitive slit.

"Good boy," Katsuki rasped, his fingers tangling in Izuku’s green curls, crushing the veil. "Now the rest. Take it all."

Izuku obeyed, forcing himself down, his nose pressing into coarse blond hair. His throat opened, convulsed, then accepted, the thick length burying itself to the root. Tears sprung to his eyes instantly. A wet, choked gurgle escaped him.

Katsuki pulled him off by the hair, just enough to let him gasp. "You love this, don't you? My cock in your throat-pussy."

"Y-yes, Daddy," Izuku choked out, saliva dripping from his chin. He dove back down, his movements becoming sloppy, desperate. He nuzzled his face into Katsuki’s heavy balls, sucking one then the other into his mouth, coating them with spit.

"Fuck, look at him go," Tetsutetsu muttered, his hand sliding down to palm the obvious bulge in his own pants. Eijiro leaned into him, his own breath hitching, his hand covering his son’s, encouraging the touch.

Katsuki began to fuck his mouth in earnest, short, brutal thrusts that stole Izuku’s air. Each drive in was met with a wet choke, a gag, a messy spill of spit. Izuku’s hands scrambled to grip Katsuki’s thighs, holding on as his head was used, his throat stretched raw.

"Such a noisy little slut," Katsuki grunted, his hips pistonning. "Let them hear how well you take me. Let them see your wedding gift."

Across from them, Eijiro had turned fully into Tetsutetsu, kissing his neck, his own hand now down the back of his son’s jeans. Tetsutetsu’s eyes were black pools of heat, fixed on Izuku’s ravaged mouth, his hips jerking slightly against his father’s touch.

Katsuki stilled, buried deep, and looked down at his weeping, gasping boy. "You want me to come down this pretty throat? On our wedding night?"

Izuku, impaled, could only make a desperate, affirmative whine. His cunt was dripping, a hot trickle of arousal running down his inner thigh.

"Then swallow it all," Katsuki commanded, and his release was a violent pulse, hot and bitter, flooding Izuku’s throat. Izuku fought to swallow, his Adam's apple bobbing frantically, tears and spit and come streaking his face.

When Katsuki finally pulled out, Izuku collapsed forward onto his hands, coughing, a final thick strand of white drooling from his lips onto the tile. He was wrecked, beautiful, and utterly owned.

Katsuki followed him down to the tiles, his knees hitting the ground on either side of Izuku’s trembling body. He didn’t bother with the clasps. He grabbed the front of the lace bodice and tore it open with a sharp rip of fabric.

Izuku’s small tits spilled free, his puffy brown nipples already hard and peaked in the night air. The ruined dress pooled around his waist, exposing his hairless, dripping cunt to the city lights.

“Present,” Katsuki growled, his hands rough on Izuku’s hips. He shoved Izuku’s thighs apart, wide, bending his knees up toward his chest. “Let your husband see his wedding cunny.”

Izuku sobbed, his fingers scrabbling at the tiles. He held himself open, his slick folds glistening, his hole clenching around nothing. “It’s yours, Daddy. All yours.”

Across the balcony, Eijiro had Tetsutetsu bent over the back of a lounge chair, his jeans around his ankles. The younger man’s thick, silver-haired cock was buried to the hilt in his father’s pussy, each thrust producing a wet, slapping sound. Eijiro’s face was pressed into the cushion, his moans muffled.

Katsuki slapped the heavy length against Izuku’s swollen cunt. The sound was sharp, obscene. Izuku jolted, a fresh gush of wetness coating Katsuki’s shaft.

“So fucking messy,” Katsuki rasped, aligning the head. “Dripping for it like a whore on your wedding night.”

“I am,” Izuku choked out, his green eyes desperate. “I’m your whore. Your wife. Please, Daddy, please fuck me.”

Katsuki drove in. Not slow. One brutal, deep thrust that buried him to the root, stretching Izuku’s tiny cunny wide around his girth. Izuku screamed, his back arching off the ground, his nails scraping concrete.

“Tight,” Katsuki grunted, his hands vise-like on Izuku’s hips. “Always so fucking tight, wife.” He pulled out almost all the way, then slammed back in, setting a punishing rhythm immediately.

The noise was filthy: the wet slap of skin, the choked cries from Izuku, the ragged grunts from Katsuki. Each thrust forced a squelching sound from Izuku’s soaked pussy.

“Look at them, Izu,” Katsuki panted, his pace relentless. “Watching you get fucked. Watching my cock wreck this pretty little cunt.”

Izuku turned his head, his vision blurry. Tetsutetsu was pounding into Eijiro with equal ferocity, his father screaming openly now, his own release splattering the cushion beneath them.

“They see,” Izuku gasped, his body jolting with each deep drive. “They see I’m yours.”

Katsuki leaned down, his mouth against Izuku’s ear. “Gonna fill this cunny with my come. Gonna breed you right here on the balcony. Let the whole city know you’re pregnant with my kid.”

His thrusts grew sharper, deeper, angling to hit the spot that made Izuku see stars. Izuku’s cries pitched higher, his legs shaking around Katsuki’s waist.

“I can feel you clenching,” Katsuki snarled. “You gonna come on your husband’s cock, baby boy? Gonna be a good wife and come for me?”

“Yes! Daddy, yes, I’m—!” Izuku’s sentence shattered into a wail as his orgasm ripped through him, his cunt convulsing wildly around Katsuki’s shaft, his release soaking both of them, a fountain of slick heat.

Katsuki fucked him through it, his own control fraying. “Take it,” he commanded, his voice raw. “Take my cum, wife.” He slammed home and held, his hips jerking as he emptied himself deep inside Izuku’s clutching warmth, a hot, pulsing flood.

He collapsed over him, his weight pinning Izuku to the cool tiles, his breath harsh in the hollow of Izuku’s throat. Izuku clung to him, boneless and full, their sweat-slick skin sticking together.

From the lounge chair, Eijiro let out a final, broken cry as Tetsutetsu stilled, his own release buried inside his father. The night air hung thick with sex and salt.

Katsuki nuzzled into Izuku’s torn lace and sweaty hair. “Mine,” he whispered, a private claim in the public dark.
