Year 522 After the Fall of the Demon King
"Little brother, wake up already!" a playful, cheerful voice sang out.
Seeing no reaction, my sister dove flat onto me like a cannonball, slamming her full weight onto my chest and wrenching a pained groan from my throat. "Agh, damn it!" I gasped, eyes snapping open as the air whooshed from my lungs. There she was, straddling my waist, her round, firm ass pressing right against my morning wood. She wore only a skimpy little shirt that barely covered her big, bouncy tits; her stiff nipples poked through the thin fabric like two pink buttons. Her thick, juicy thighs clamped my sides, and her warm pussy ground against my hardening cock through the sheet.
"You crazy bitch!" I growled, trying to shove her off, but she just laughed and leaned forward, smothering my face with her soft, heavy melons. "How many times have I told you not to wake me like this, fuck!" She puffed out her chubby, adorable cheeks in a mock pout, but her eyes sparkled with mischief. "Don't be like that on your birthday, little brother! You're turning 16 today; you're a real adult now!"
True enough. Today was my 16th birthday, the day the Kingdom of Murk declared a boy a man: he could marry, inherit land, bear arms… and take on adult duties. Sixteen years ago, I reincarnated into this body as Jimmy Lee, son of a humble farming family on the dusty outskirts of the kingdom. But my mind came from another world—from the grimy streets of New York's Chinatown, where I was a feared gangster called Fenhei. I didn't do it for greed alone; I robbed, extorted, and killed to pay for my sick mother's medicine and keep my little sister safe from debt. But a rival triad betrayed us: they broke into our home, raped and slit my mother's throat in front of me, then did the same to my sister while I struggled in chains. Mad with rage and grief, I put my own gun to my temple and pulled the trigger.
And I woke up… as a squalling infant in the arms of an exhausted but smiling woman—my new mother—with my rough, quiet father beside her, and a little girl—my current big sister—peering at me with huge eyes and cooing, "He's so cute, my baby brother!" That's when I knew I'd reincarnated into a medieval fantasy world, straight out of the isekai novels I used to read to escape. I learned the local tongue—an archaic, guttural English—and adapted to farm life: milking cows, plowing fields, hunting rabbits. I felt that lost family warmth again: my father's calloused hands, my mother's cushy hugs, and the naughty games with my big sister, who now rode me like her personal stallion.
I swore silently, as her hot pussy kept grinding against my swelling cock: I'd give everything to protect this new family. I'd kill, steal, do whatever it took. No one would lay a finger on them. Not my mother, not my father… and not this horny sister now grinning wickedly, jiggling her juicy tits over my face.
"Little brother, snap out of it!" Alexia hollered, yanking me from my memories. "Mom and Dad are waiting at the table with the cake!"
My big sister Alexia, 22, stood there with her fiery red hair in twin pigtails and sparkling blue eyes. She was a stunner, but her tits were obscene, massive udders that sagged like a dairy cow's, heavy and pendulous, nipples thick as thumbs poking through her skimpy nightshirt. Her ass was a monstrous, wrinkled globe that jiggled with every step. The shirt barely reached mid-thigh, and the sight of her blood-related curves made my cock throb painfully.
I'd slept naked; only the sheet hid my lower half. Impatient, Alexia grabbed the blanket and ripped it away. "Get dressed already!" My enormous cock sprang free, thick as a wrist, veiny and already leaking pre-cum. She didn't blush. She grinned.
"Well, well," she purred, licking her lips. "Looks like you need milking again. I drained the cows dry this morning, so handling you should be easy."
I wanted to protest, but it was useless. For a year now, we'd been tangled in this twisted, Alabama-style incest. It started one stormy night when she crawled into my bed, terrified of thunder. One thing led to another, her virgin blood on my sheets, my first time in this world. Since then, she'd been raping me daily, claiming a hard-on made field work impossible. Truth was, she'd turned into a cock-addicted slut.
Before I could speak, she shoved me flat on my back and straddled me, her dripping pussy hovering over my shaft. "Giddy-up, little brother!" she whooped like a cowgirl, slamming down in one brutal drop. "Yee-haw!"
"Plap! Plap! Plap!" Her monstrous ass clapped against my thighs as she rode me like a bucking stallion. Her udder-tits flopped wildly, slapping my chest with wet "smack! smack!" sounds, milk already leaking from her fat nipples. She yanked her pigtails like reins, grinding her sloppy cunt down to the root.
"Take it, you big-dicked stud! Gimme that birthday cum!" she bellowed, bouncing harder. "Plap-plap-plap!" Her wrinkled ass rippled with every thrust, pussy walls squeezing like a fist. I groaned, hips bucking involuntarily as she milked me.
"Ahh! Ahh! Ride 'em, cowgirl!" she moaned, tossing her head back. "Spurt! Spurt!" The first load blasted into her, painting her womb white, but she didn't slow. "That's one! Keep 'em coming!"
"Plap! Plap! Plap!" She spun around reverse-cowgirl, planting her feet on either side of my hips, ass cheeks spreading to show my cock disappearing into her stretched hole. "Look at that fat dick wrecking your sister's cunt!" she laughed, slamming down. "Smack! Smack!" Her tits swung like pendulums, spraying milk across the bed.
I came again, "Spurt! Spurt! Spurt!", filling her until it leaked out in thick ropes, but she kept riding. "Third load, little brother! You're my personal cum-pump!" Her pussy clenched, "squish! squish!", draining every drop. By the fifth orgasm, I was a whimpering mess, cock raw and balls aching, but she finally slowed, grinding deep.
"Happy birthday," she panted, leaning down to kiss me, cum and milk dripping from her chin. "Now get up. Cake's waiting, and I've still got morning chores." She popped off with a wet "plop!", my spent cock flopping against my stomach, coated in her juices and my own seed.
We shuffled into the kitchen, my face chalk-white and hollow, while Alexia glowed like a freshly milked heifer. Dad—Jon—took one look at me and barked a laugh. "Sixteen and already legal, but you look like a dried-up old goat of eighty!" He had no idea my sister had just wrung me out like a rag.
I slumped into the chair across from him; Alexia slid in beside me, thighs brushing mine. A massive sponge cake thudded onto the table, delivered by Mom—Eris—blonde hair cascading to her waist, blue eyes twinkling. Her tits were obscene, two planet-sized orbs that swallowed half her torso, swaying like overfilled wineskins under her apron. Her ass was a jiggling mountain that strained the seams of her dress. I swallowed hard, cock twitching despite the abuse. She caught my stare and winked, knowing exactly what her "little man" was thinking. I was head-over-heels in love with her—blood be damned—and jealous as hell of Dad for getting to bury himself in that every night. But duty first: protect the family, no matter the cost.
We dug into the cake. Dad urged me to hurry. "Eat fast, boy. Got your birthday gift ready." I shook my head. "No need, Pa. I'm not a kid, and we can't spare a bronze coin." The Lee farm was bleeding money; crops barely fed us. My Farmer-class magic was still too weak to yield bounty, and Dad's Merchant skill only stretched so far at market.
Under the table, something warm and slick wrapped around my spent cock. Alexia's hand, of course. She shot me a sideways smirk while her fingers pumped me back to life, slow and deliberate. "Fap… Fap…" the faint wet sound hidden beneath the clatter of forks. The shameless slut.
We finished the cake in tense silence, my legs still jelly from Alexia's morning ride. We finished the cake and I was dying to know what the hell this "free gift" was. Dad's face suddenly went stone-cold serious.
"Jimmy, come with me to the woods. Now."
He stood up and walked out without another word. Mom and Alexia looked at each other, confused; I just followed, heart already hammering.
Ten minutes later we stood in front of the old stable, the one Grandpa had forbidden us to even look at when we were kids. The boards were grey and rotten, the lock rusted solid.
Dad turned the key he'd kept hidden for decades and pushed the doors open.
Inside, the smell of sweet hay and warm musk hit me first. Then I saw them: three unicorn mares, each with a distinctly different coat color, silver horns glinting… but wrong. Their faces were almost human, soft feminine lips, long-lashed eyes that stared straight at me. Between their front legs hung enormous, milk-swollen breasts, each pair bigger than Mom's, swaying heavily, fat teats dripping. Their hindquarters were thick, wrinkled, unmistakably female, tails flicking over plump, glistening cunts.
"…Father, what the fuck is this?" I asked.
He closed the door behind us and leaned against it, coughing into his sleeve. When he pulled it away there was blood.
"Listen to me, son." His voice cracked. "I don't have much time left. This sickness… it's eating me from the inside. Weeks, maybe months. Eris and Alexia don't know. You're the only one I'm telling."
It was like a punch in the stomach to hear that suddenly another loved one of mine was going to die. Not again. I whispered hysterically, "No... no... no..No..." Jon grabbed my shoulders with trembling hands to calm me down.
He grabbed my shoulders hard, eyes fierce. "Stop. Breathe. Look at me." I did, tears already rolling. "The stable is yours now because you're the first descendant in three generations to awaken the Farmer class, same as my Father. He made me swear: the day one of family awake farmer class, was to give this." He pressed a thick, wax-sealed letter into my trembling hand.
Father kept talking, voice raw. "You know what the Beast Coliseum is?"
"Everyone knows," I whispered. "Every five years. Poor bastards fight monsters and each other to death for a noble title and a mountain of gold. Rich pricks watch and bet. This year it starts again."
Dad nodded. "Our real name isn't Lee. It's De Eroine. Centuries ago we ruled the Kingdom of Eroine. After the Fall of Demon King, Eroine fell. We bent the knee to Murk or we'd have been wiped out. They stripped our titles, spat on our crest, and scattered us. Great-grandfather burned the family banner, changed our name, and hid us here as dirt farmers so we'd survive."
He coughed again, more blood. "I'm "defective". You, Jimmy… James De Eroine… you're the only one who can bring our Family us back to the top. Win the coliseum. Take the prize. Give your mother and sister the life they deserve."
I was shaking so hard the letter rattled in my hand.
"Promise me," he rasped, gripping my wrist until it hurt. "When I'm dead, you enter that arena and you take back what's ours."
Tears blurred everything. "I promise, Father. I swear on my life."
He wiped his mouth, and forced a grin. "Now let's go home before your mother suspects something. We'll tell them I took you to a brothel for your first lay."
Back at the house, Mom raised an eyebrow. "Where'd you two disappear to?"
Dad slung an arm around my shoulders, voice suddenly light. "To a brothel. So Jimmy could pop his cherry with a woman."
Mom's eyes sparkled. "About time! Did my son enjoy his first whore?"
I forced a nod. "Yeah… real professional."
Mom grinned "That's good! A boy needs to become a man. But you, darling..." her smile turned sinister: "...better not have touched any whores, or I'll cut that little mushroom off."
Dad paled, sweating: N-not a finger, love, I swear!"
From the corner, Alexia glared pure murder at me, lips moving silently: You cheating bastard.
Night had fallen, the house silent except for the wet "Fap… fap… fap" of Alexia's enormous, milky-heavy tits sliding up and down my cock. She had me pinned to the bed, pigtails bouncing, face twisted in jealous fury.
"That street whore couldn't do this, could she?" she hissed, squeezing her pendulous udders together until my shaft vanished between them. "These tits are one of a kind, little brother. No one whore can milk you like your big sister. No one."
I barely heard her. Dad's blood-flecked smile and his dying promise kept looping in my head. Win the coliseum. Take back our name. I wasn't even hard from pleasure—just from the mechanical friction.
Alexia noticed. Her eyes narrowed. "You're thinking of her, aren't you?"
That snapped something. I lunged forward, grabbed her pigtails, and crushed my mouth against hers. She gasped, then kissed back hungrily, tongue wrestling mine. I shoved her onto her back, spread those thick thighs, and rammed my cock into her hairy blonde cunt in one brutal thrust.
"Plap! Plap! Plap! Plap!"
"Ahhn! Yes! Fuck me, Jimmy! Fuck your sister until I forget you ever touched another woman!" she screamed, legs locking around my waist, heels digging into my ass. Her giant tits flopped wildly with every thrust, milk spraying across both of us. "Harder! Punish me! Fill me up!"
I pounded her like a beast, hips crashing, bed creaking, trying to drown the grief in her body. I was seconds from exploding inside her when—
BAM!
The door flew open.
Mom stood in the doorway, face streaked with tears, eyes wild and red. For one frozen heartbeat she saw everything: me buried balls-deep in my own sister, Alexia's legs spread wide, pussy stretched around my cock, milk and juices soaking the sheets.
But the horror on her face wasn't about us.
"Jon is dead!" she screamed, voice cracking.
My cock still throbbed inside Alexia, but the world went cold.
Alexia's legs slipped from my waist. My cum spilled uselessly into her as the orgasm hit anyway, ruined.
Dad was dead.
