The first bird sang, a single clear note that sliced through the canvas. It didn’t break the silence in the tent; it underlined it. Izuku watched his father’s face in the weak, gray light. Katsuki’s eyes were open, fixed on the tent ceiling, but he wasn’t seeing it. There was no regret there. Just a heavy, stunned ownership, like a man surveying the ashes of a house he’d chosen to burn down himself.

“You’re awake,” Izuku whispered. His throat was raw.

Katsuki’s head turned on the shared pillow. His storm-colored eyes tracked over Izuku’s face, slow, assessing. “Been awake.”

“Thinking?”

“Not thinking.” Katsuki’s voice was a gravelly scrape. “Just… being in it.”

Izuku understood. The space between them in the big tent was charged, different. It hummed. He shifted, the sleeping bag rustling, and the movement made him aware of the dull, pleasant ache between his thighs, the ghost of being claimed. He bit his lip. “Does it feel real yet?”

“Feels like the only real thing,” Katsuki said, and the truth of it hung there, monstrous and beautiful. A second bird joined the first, a conversation starting outside. “Morning.”

Izuku’s hand crept across the space, his fingers finding the back of Katsuki’s hand where it rested on his own stomach. He traced the rough knuckles, the scars from old work. “You chose me.”

“I said I did.”

“Say it again.”

Katsuki turned his hand, capturing Izuku’s. His grip was firm, almost painful. “I chose you, Izuku. I’m choosing you. Right now, in this fucking tent, with the birds singing. That’s the truth.”

Izuku’s breath hitched. He pushed the sleeping bag down, the cool dawn air hitting his bare chest. He guided Katsuki’s captured hand, placing it flat over his heart. “Feel that?”

Katsuki’s palm was searing hot. He could surely feel the frantic, rabbit-fast beat under his son’s ribs. A rare warm smile crosses Katsuki's lips. “Yeah.”

The warm smile on Katsuki’s lips faded into something harder, more resolved. He kept his hand over Izuku’s heart. “We’re not going back.”

Izuku blinked. “What?”

“Home. To her. We’re not going back.” Katsuki’s voice was low, final. “She’ll never be okay with this. It’s better if we disappear. Start the new life.”

Izuku’s heart hammered against his father’s palm. “Disappear?”

“Yeah.” Katsuki pulled his hand away and sat up, the sleeping bag pooling around his waist. He reached for his phone on the tent floor. The screen glowed in the dim light. He found the contact, thumb hovering. “We hide that we’re father and son from now on. To everyone.”

He pressed the call button. Put the phone to his ear. Izuku watched, holding his breath. The ring was audible in the quiet tent.

“Katsuki? Honey, is everything—” Inko’s voice, tinny and concerned, leaked from the receiver.

“Inko.” Katsuki’s tone was flat, a stranger’s. “Listen. Izuku and I… we’re extending the trip. Indefinitely.”

“Indefinitely? What does that mean? His school—”

“No, listen,” Katsuki cut her off, his voice a low, cold blade. “It’s not a trip. Izuku and I are together. In love. We’re starting a new life. Just the two of us. As a couple.”

The silence on the line was absolute, then a sharp, fractured inhale. “What?” Inko’s voice was a tiny, broken thing. “Katsuki, that’s not funny. That’s a sick—”

“It’s not a joke.” He looked at Izuku, his stormy eyes holding him there. “Putting you on speaker.” He tapped the screen, and the tent filled with the shallow, panicked sound of Inko’s breathing.

“Izuku?” Her voice was a desperate plea. “Baby, tell me he’s lost his mind. Tell me this is some fucked-up joke.”

Izuku’s throat closed. He looked at his father’s face, at the resigned, brutal honesty there, and he felt the last tie to his old life snap. He wet his lips. “It’s true, Mom.”

A raw, guttural noise came through the speaker—a sob choked into a scream. “No. No! Izuku, he’s your father! My God, what has he done to you? What has he made you—”

“He didn’t make me do anything!” Izuku’s voice cracked, loud in the confined space. “I wanted it. I want him. I’m in love with him.”

The confession hung in the humid air, mingling with Inko’s hysterical weeping. “You’re sick. Both of you! You need help! Katsuki, you bring him home right now! Right now!”

“We’re not coming home, Inko,” Katsuki said, his tone devoid of all warmth. It was just fact. “Ever. You need to understand that. We’re gone.”

“He’s my son!” she shrieked, the sound tinny and distorted. “My baby! You stole my baby!”

“He’s a man,” Katsuki growled, his control thinning. “And he’s mine now. In every way.”

Izuku flinched at the possessiveness, a hot-cold thrill shooting down his spine. He saw Katsuki’s free hand clench into a fist on his bare thigh, the muscles in his forearm corded tight. Inko was sobbing, words dissolving into unintelligible grief and rage.

Katsuki’s eyes never left Izuku’s. “We’re done here.” He moved to pull the phone away.

“Wait!” Izuku whispered, his hand darting out to grasp Katsuki’s wrist.

“Fuck me,” Izuku whispered, his fingers tightening on Katsuki’s wrist. The phone was still between them, Inko’s shattered breathing the only sound. “Right now. Let her listen.”

Katsuki’s red eyes widened, then narrowed, understanding flooding them with a dark, possessive heat. A slow, grim smile touched his lips. He brought the phone back, his voice a low, deliberate rumble. “You hear that, Inko? Your son’s begging for it.”

Katsuki dropped the phone onto the sleeping bag between them, the speaker still live. He didn’t look away from Izuku as he gripped his hips and flipped him onto his stomach with a single, brutal motion.

“You want her to hear?” Katsuki’s voice was a gravelly whisper, his hands pushing Izuku’s thighs apart. “Then scream for her.”

Izuku buried his face in the bunched-up fabric, his back arching. He was already wet, his tiny pussy slick and throbbing. “Do it.”

Katsuki spat into his palm, a crude, wet sound. He smoothed it over his thick, uncut cock, the head already flushed and leaking. He positioned himself, the broad tip nudging against Izuku’s soaked entrance. “Tell her what’s happening.”

“He’s—” Izuku gasped, the pressure immense. “He’s pushing inside me, Mom.”

A choked whimper came from the phone’s speaker. Katsuki drove forward, a single, deep, unforgiving thrust that buried him to the hilt. Izuku screamed, a raw, shattered sound that filled the tent.

“That’s it,” Katsuki grunted, his hips flush against Izuku’s ass. He stilled, letting them both feel the full, impossible stretch. “Let her hear how full you are. How you take your father’s cock.”

“I feel it… everywhere,” Izuku sobbed, his fingers clawing at the sleeping bag. The pain was a bright, searing thread, weaving into the pleasure until he couldn’t tell them apart.

Katsuki began to move, a slow, grinding withdrawal followed by a hard, snapping return. The wet, filthy sound of their joining was obscenely loud. Each thrust jolted Izuku forward, his small tits rubbing against the rough fabric. “You like that? Knowing she’s hearing me fuck her son’s cunt?”

“Yes! God, yes!” Izuku cried, his voice breaking on another drive. His own arousal dripped down his inner thighs, making a mess of them both. “She can hear how wet I am for you. Only you.”

Katsuki’s pace turned punishing, his balls slapping against Izuku’s skin with every plunge. Sweat dripped from his chin onto the knobs of Izuku’s spine. The tent was an oven, filled with the musk of sex and the tinny, static silence from the phone. “Come on, scream for her. Let her know whose you are.”

“Yours!” Izuku shrieked, his body tightening. “Daddy, I’m yours!”

The vulgar term, broadcast to his weeping mother, seemed to ignite something feral in Katsuki. He hooked an arm around Izuku’s waist, hauling him up onto his knees, back pressed flush to Katsuki’s sweat-slicked chest. He never stopped moving, the angle now deeper, hitting a place that made Izuku see white.

“Look at it,” Katsuki growled in his ear, his hand snaking down Izuku’s stomach, fingers delving into the wet, tangled hair. He pressed, making Izuku feel the thick outline of his own cock stretching him from the outside. “Feel what I’m doing to you. What she’ll never have again.”

Izuku’s head fell back against Katsuki’s shoulder, his mouth open in a silent, desperate cry. His own hand flew to his clit, circling frantically. The orgasm built, a terrifying wave. “I’m gonna cum. Please.”

“Do it,” Katsuki snarled, his thrusts becoming ragged, losing rhythm. “Come on your father’s cock while your mother listens. Show her what we are.”

The command shattered him. Izuku came with a broken wail, his pussy clenching violently around the intrusion, his whole body seizing and his cunt squirting all over. Katsuki swore, his own control snapping. He buried himself deep and stilled, a guttural groan ripping from his throat as he emptied himself inside his son.

For a long moment, the only sounds were their ragged breaths and the wet, messy aftermath. Then, a faint, broken click came from the phone. The line went dead.

Silence, real and heavy, settled in the tent. Katsuki slowly pulled out, the sound obscene in the new quiet. Izuku collapsed forward, trembling. He turned his head, his green eyes finding his father’s. There were no words. The dawn light, seeping through the nylon, showed the stark truth on their skin: the sweat, the marks, the proof.

Katsuki reached over and picked up the silent phone. He stared at the black screen for a long time. Then he dropped it again. It was over. Everything was.

The floorboards of the log cabin were cold under Katsuki’s bare feet, but the great room was warm, lit by the orange glow of a massive stone fireplace. Six months. The scent here was different—pine resin, wood smoke, and the clean, cold air that seeped in from the towering evergreens outside. Izuku stood at the wide window, his silhouette framed against the grey Pacific Northwest light, one hand resting on the pronounced swell of his stomach. On his left hand, a simple platinum band caught the firelight. On Katsuki’s own, a matching ring felt heavier than any tool he’d ever held.

“You’re staring,” Izuku said, not turning around. His voice was quieter now, less a nervous stream and more a settled current.

“Yeah,” Katsuki said, his own voice a low rumble in the quiet cabin. He walked over, the floorboards creaking under his weight. He stopped behind Izuku, not touching him yet. “Can’t help it.”

Izuku leaned back, letting his head rest against Katsuki’s shoulder. Katsuki’s hands came up, spanning the curve of Izuku’s belly, feeling the hard, warm weight of it. He could feel the baby shift, a slow, rolling motion beneath his palms. “She’s active today.”

“He,” Katsuki corrected, his thumbs rubbing slow circles. The doctor had been uncertain, but Katsuki had decided. A son. His son, carrying his son. The thought was a closed loop of fire in his chest.

Izuku hummed, a soft sound. “You’re so sure.” He turned in Katsuki’s arms, his green eyes searching Katsuki’s face. The freckles stood out against his skin, which had taken on a new, ripe softness. “Does it scare you? Any of it?”

“The world?” Katsuki’s red eyes were steady. “Yeah. This?” He let one hand slide down, over the swell, to press gently against the damp cotton of Izuku’s sleep shorts. He felt the heat, the softness there. “This is the only thing that doesn’t.”

Izuku’s breath hitched. His own hands came up to frame Katsuki’s jaw. “Kiss me.”

It wasn’t a request. Katsuki obeyed, leaning down to capture Izuku’s mouth. The kiss was slow, deep, a tasting. It tasted of mint tea and the unique, sweet musk of pregnancy. Katsuki’s tongue swept in, claiming, and Izuku opened for him with a soft sigh, his fingers tangling in the blond spikes of Katsuki’s hair.

When they broke apart, both were breathing harder. Izuku’s eyes were dark. “I need you,” he whispered, the words raw and simple. “I ache everywhere.”

Katsuki didn’t speak. He hooked his fingers into the waistband of Izuku’s shorts and underwear, pushing them down over the curve of his ass, letting them pool at his feet. The firelight played over Izuku’s body—the full, heavy breasts, the dark thatch of curls between his thick thighs, already glistening. Katsuki’s cock, huge and uncut, strained against his own sweatpants, a dark patch of pre-come already soaking through the fabric.

“On the rug,” Katsuki said, his voice gravel. “On your side. It’s easier.”

Izuku went, lowering himself with careful grace onto the thick sheepskin before the fire. He lay on his side, one thigh hitched up. The view was obscene: his pregnant belly, his slick, pink pussy exposed and waiting, already dripping onto the white fur. Katsuki shucked his sweatpants, his cock springing free, thick and veined and leaking. He knelt behind Izuku, his hand smoothing over the curve of Izuku’s hip.

“Tell me,” Katsuki growled, the head of his cock nudging against Izuku’s soaked folds. He didn’t push in. Not yet.

“I’m empty,” Izuku breathed, pushing his hips back, seeking the pressure. “I’m so empty without you in me. Please, Daddy. Fill me up. I need to feel you.”

The word did it. Katsuki pressed forward, not a thrust, but a slow, inexorable invasion. The head popped past the tight ring of muscle, and Izuku cried out, his back arching. Katsuki went still, buried to the hilt, his balls pressed against Izuku’s ass. The stretch was immense, breathtaking. Izuku’s cunt fluttered around him, hot and silken and desperately tight. “Fuck,” Katsuki gasped, his forehead dropping to Izuku’s shoulder. “You’re so fucking tight still.”

“I feel you,” Izuku sobbed, his hand reaching back to clutch at Katsuki’s thigh. “In my stomach. I can feel you. Move. Please, move.”

Katsuki began to rock, short, grinding motions that made Izuku whimper. The wet sound of their joining was loud in the quiet cabin, underscored by the crackle of the fire. Each slow drag made Izuku’s breath catch. Katsuki’s hand found Izuku’s clit, circling the swollen nub with a rough, calloused thumb. “This what you needed? My cock in your pregnant cunt?”

“Yes,” Izuku chanted, “yes, yes, it’s what I need, it’s all I need—” His words dissolved into a moan as Katsuki’s thrusts deepened, still slow, but harder now, each one punching the air from Izuku’s lungs. The pleasure built, a heavy, coiling heat in Izuku’s gut, different from before—deeper, more profound. He felt impossibly full, claimed, rooted to the earth by the man splitting him open and the life swelling within him.

Katsuki’s rhythm began to fray, his hips stuttering. He was close. He bit down on the juncture of Izuku’s neck, not hard enough to break skin, but enough to brand. “Gonna come inside you,” he grunted, his voice shattered. “Gonna fill you up. My son. Mine.”

The possession in the words tipped Izuku over the edge. His orgasm ripped through him, silent for a second before a broken scream tore loose. His pussy clamped down, milking, squeezing, and he felt a hot gush of release wet the fur beneath them. Katsuki roared, driving in one last, brutal time and holding, his body rigid as he emptied himself in thick, pulsing waves deep into Izuku’s womb.

They lay locked together, trembling, as the fire popped. Katsuki’s softening cock was still snug inside Izuku, a reminder of the connection. Izuku’s hand drifted back to his stomach, and he gasped. “She’s… he’s moving. Like crazy.”

Katsuki shifted, pulling out slowly. He lay down on the rug facing Izuku, his hand replacing Izuku’s on the taut skin. He felt the frantic, joyful kicks against his palm. A slow, real smile, one of those rare, startling things, spread across Katsuki’s face. “He knows his father’s home,” he said, his voice rough with wonder.

Izuku watched that smile, and the last shadow of the old world—the tent, the phone, the screaming—finally dissolved. Here, in this sacred, sinful cabin, was the first truth of their new dawn. It was terrifying. It was theirs.
