Transmigrated As A Stepdad In A Fantasy Doujin World

Chapter 1: 1. A New Fantasy World

Kael had her pinned to the black silk, his 6’6” frame covering her completely. The petite 20-year-old vampire beneath him looked almost breakable against his size.

Barely five-two. Narrow shoulders. A slim waist he could nearly span with both hands.

Soft pale curves that still managed to be lush in the places that mattered.

Full heavy breasts for her small frame, the soft flesh spilling slightly under his chest with every hard thrust.

Wide hips that flared sharply from that tiny waist, thick enough that his fingers sank into them when he gripped her.

Soft pale thighs that trembled and spread wide around his hips.

Silver-white hair fanned across the sheets. Crimson eyes half-lidded and glassy. Tiny fangs visible behind parted lips that kept gasping his name.

She was his stepdaughter by the old border rites. Bound to him by the blood-vow they had sealed only hours ago. Taboo. Wrong. And neither of them cared.

”Fuck. Dad.”💖

Seraphine’s voice cracked on the title, high and shaky.

”Harder. Please.”

Kael drove into her with deep brutal strokes, the thick length of his cock stretching her tight cool cunt on every thrust.

Schlick... Schlick... Schlick.

The wet sound of it filled the room under the creak of the bed. Her petite body jolted with every impact, those soft breasts bouncing, the little vampire’s moans spilling out in short broken bursts.

”Ah... Ah... Nnh.”

He had one big hand locked around both of her wrists above her head, the other gripping the soft meat of her hip hard enough to leave marks.

His cock dragged almost all the way out before slamming home again, bottoming out against her cervix.

Slap.

Skin on skin. She was so small under him that every thrust made her entire body rock up the bed.

”You feel that?” he growled against her throat, voice rough. ”Your stepfather’s cock buried to the hilt in his little girl. Taking every fucking inch like you were made for it.”

Seraphine’s answer was a high desperate moan. Her walls fluttered and clenched around him, cool and slick and impossibly tight.

”Yes. Ahhn. Yes, Father. Use me. Claim me as yours.”💞

He fucked her harder. The pace turned punishing.

Plap... Plap... Plap.

The wet sound of his hips against her soft ass and the underside of her thighs grew louder, faster. Her petite frame shook with every thrust. Soft breathy cries left her mouth in time with the rhythm.

”Hnn... Ah... Ah... Fuck.”💓

Kael released her wrists only long enough to shove both of her legs up, folding the small vampire nearly in half so her knees pressed toward her shoulders.

The new angle let him sink even deeper. He watched his thick cock disappear into her again and again, stretching her pretty pink folds wide, the slick sheen of her arousal coating his shaft and dripping down onto the silk.

Seraphine’s crimson eyes rolled. Her mouth fell open on a continuous shaky moan as the head of his cock battered that deep sensitive spot inside her.

”I’m... Ahhn... I’m gonna cum, Dad.”💞

”Dad... my pussy is better than that old hag succubus, right?”😈

”Come on your stepfather’s cock,” he ordered, voice low and rough as she talked about her mom with a disgusting tone.

”Soak it. Show me how much my little girl needed this.”

Her orgasm hit hard. The petite body arched under him, silver hair thrashing against the sheets, a long broken cry tearing from her throat as her cunt spasmed and gushed around him.

”Ahhn—yes—!”💕

Schlick... Schlick... Schlick.

The wet sounds turned messier as he kept fucking her straight through it, chasing his own release.

He lasted only a few more brutal strokes.

With a deep guttural groan he buried himself to the root and came, thick pulses of cum flooding her tight fluttering heat.

Seraphine whimpered at the feeling, still twitching, still clenching around him as he emptied himself inside his stepdaughter.

”Mmm... so full...”

For a moment the only sounds were their heavy breathing and the soft wet drip of excess cum leaking out around his cock where they stayed joined.

Kael stayed deep inside her, looking down at the small thoroughly used vampire beneath him.

Flushed cheeks. Swollen lips. Silver hair a wreck. Soft breasts rising and falling fast. Thighs still spread wide and trembling around his hips.

Seraphine’s voice came out soft and wrecked, almost a whisper.

”Again. Don’t pull out. Fuck your little girl again while you’re still hard inside me.”

Kael’s cock twitched at the words. He rolled his hips once, slow and deep, watching her lashes flutter and a fresh shaky moan slip free.

”Greedy little thing,” he muttered, already starting to move again. Longer heavier strokes this time, grinding deep so she felt every inch of the taboo stretch.

Schlick... Schlick... Schlick.

And Seraphine’s soft needy moans rose to meet them.

”Ah... Dad...”💕

We have to look back a few weeks ago to understand how this came to this.

A few weeks earlier.

Kael (No, that was not his name in the real world) had been drowning in fluorescent light and spreadsheet hell for sixteen straight hours.

The office was a glass-and-steel cage on the thirty-fourth floor.

His real name had been meaningless even to himself by then.

Just another mid-level corporate drone who had not seen the sun in days. Deadlines stacked like corpses.

Bosses who spoke only in KPIs. The kind of life where sleep was a rumor and caffeine was religion.

By 3:17 a.m. the building was empty except for the cleaning bots and him.

He finally shut the laptop, eyes burning, shoulders locked into permanent knots.

He rode the elevator down in silence, stepped out into the wet midnight streets, and immediately regretted every life choice that had led him here.

He bought a bottle of cheap whiskey from a corner store that never closed. Drank half of it while walking. The city blurred into neon smears. His thoughts were sludge.

He never saw the delivery truck.

One second he was muttering curses at the empty sidewalk. The next, headlights exploded across his vision, metal screamed, and the world ended in a wet, bone-cracking impact.

Darkness.

Then warmth. Soft. Heavy. Like being lowered into silk sheets that smelled of night-blooming flowers and sex.

A voice curled around him, low, amused, soaked in velvet and sin.

It was not just a voice.

It was pure, distilled lust given sound. Every syllable slid down his spine like a tongue, coiled low in his gut, and squeezed.

The kind of voice that could make a man spill untouched in under a second if she simply whispered his name the right way.

His new body, still forming, still raw, twitched hard just from the sound of it.

”Rise, little broken thing.”

He opened eyes that were no longer his.

She stood before him in a realm that had no walls, only endless twilight and floating platforms of black marble veined with gold.

Her body was pure invitation.

Curves that defied physics, skin like polished ivory, hair a cascade of living crimson that moved on its own.

Horns of polished obsidian curled back from her temples. Between her thighs a soft glow pulsed in time with a heartbeat that was not quite human.

”I am Lysara,” she said, and the words alone made his cock throb so violently he nearly came right there.

”Goddess of Lust. Devourer of Virtues. Patron of every filthy, beautiful, forbidden thing the self-righteous pretend not to crave.”

She circled him slowly, one clawed fingertip tracing the air just above his chest.

Her voice poured over him again, soft, husky, dripping with the promise of absolute ruin.

”You died alone, exhausted, and utterly unfucked by life. Pitiful. I have a better use for that stubborn spark of yours.”

The goddess stopped in front of him, close enough that the heat of her body made his new senses flare.

”I will drop you into another man’s flesh. A human body already tangled in power, blood, and taboo. You will wake as someone the world already fears and desires. Your task is simple, deliciously so. Conquer this world. Break its heroes. Especially the self-righteous shining knight who believes himself the moral center of the universe. Crush him. Claim everything he protects. And while you do it...”

Her smile widened, wicked and knowing. That voice dropped even lower, velvet and lethal.

”...indulge. Thoroughly. I am the Goddess of Lust, after all. I do not reward abstinence.”

He found his voice, rougher than before, already carrying the weight of the body he would soon inhabit.

”A system,” he said, fighting the urge to thrust into empty air just from the way she spoke. ”Something. Anything. Stats. Skills. Quests. I am not walking into a new world blind.”

Lysara laughed, the sound like silk tearing over wet skin, and the laugh alone nearly finished him.

”Greedy. I like that.”

She snapped her fingers.

A translucent crimson interface unfolded in front of his vision, elegant, almost erotic in its design.

”There,” Lysara purred, and the purr alone made his balls draw up tight.

”Your leash and your whip in one pretty package. Every time you break a taboo, every time you make someone moan your name in ways society forbids, the system feeds you. Grow strong enough and even gods will kneel.”

She leaned in, lips brushing the shell of his ear.

Her next words were barely a whisper, yet they hit him like a direct stroke along the underside of his cock.

”As for the rest of your new life, the family waiting for you, the bonds already sealed in blood and vow, that, my delicious little mortal, is a surprise. Wake up and find out about the new world.”

The realm shattered.

He gasped awake in a body that was taller, stronger, purely human, yet already humming with the system’s dark hunger.

Six-foot-six of lean, hard muscle.

A defined six-pack cut sharply across a flat stomach. Broad shoulders tapered into a narrow waist.

His new face was sharp and striking with high cheekbones, a strong jaw, and clear blue eyes under a fall of blond hair that still felt foreign against his skin.

The scent of black silk and cool night air filled the chamber around him, but the bed beside him was empty.

The system pulsed once, hungry.

[Quest Active: Claim Your Vampire Stepdaughter]

Kael’s new lips curved into a slow, dark smile.

He had died a corporate slave.

He had been reborn a human predator with a goddess’s blessing and a system built for sin.

The night and the weeks that would follow were only beginning of his new path in this world of heroes and devils.
