Chapter 40: Chapter 40: Knotting My Sister (R18)

I stood up, staring down at the mess her fluids and my tongue had caused… my canine lips shining with her fluids while her pussy gleamed with her sticky lubricant.

“Aki, how do you want to become a woman? What position do you want, rough or gentle? My Knott will be a bitch once I get lost in lust again…” I warned her as my veiny cock was throbbing against her cheek—even now, small jets of cum were bubbling from the tip and spurting on her face as she rubbed her nose against my glans.

Her expression changed… not lust, but pure love was reflected on her blue irises.

“Brother’s choice.” Aki gave me control with those words; her faith was given to me, the most important thing a human has, his mind… and my beloved sister had given me hers without hesitation.

Her pink folds spread open, her honeypot clamping down, waiting to be filled, and her hungry womb awaited my cum, her legs resting over the arms of the leather armchair while her wet cunt, glistened like a fresh orchid.

My precum covered Aki’s abdomen, a sticky, clear fluid; her delicate hands wrapped around my shaft, smearing her abdomen as her tongue licked it, giving the sticky liquid an erotic appearance… the beast inside begged to claim its mate.

Without another word, the blunt, hard, and spongy head pressed against my sister’s delicate opening, but I resisted pulling away. I lifted her into the air, my muscles tensing as she was in my arms, and looking at me with a strange look, maybe worried I had second thoughts. Her eyes began to tremble and fill with tears.

“Aki.”

I called her name before I kissed her, feeling her lips relax, her tears dripping down my cheek, her tongue entangled with mine, and a new flavour invaded my mouth as I savoured the sweet taste of her kiss and the salty tears dripping down, combining with our saliva.

Her hips lowered… Aki gasped; her tears stopped while our bodies united; I broke our kiss, and a single thread connected us.

“Brother… Mmmn~ It feels hot inside.”

Our breaths hitched for a second, both experiencing an unknown sensation… my cock felt as if a heated sleeve was engulfing my hard member; I didn’t even realise my cock had entered her, the hot, slimy walls wrapping around me and stimulating the tip… my sister’s maiden flower had broken.

Slowly, I moved Aki down.

“Ugh, It’s deep inside~ Brother!! Aki can feel you better than I did myself~ You are marking this bitch, oh shit!!”

“Sis, you are too tight… this isn’t something you do without training; wait a second…” My love for her, a secret love I held for more than I could remember, stopped me from ravishing her as my cock throbbed as if to order me to plunge into her.

“Aki, I’ve always loved you. I hope you remember this night for the rest of your life.” My voice sounded sexier and different from normal, a little deeper and with a slight reverb, as I gently pushed her onto the small bed, lifting both her legs; as her feet rested against my shoulders, I looked down at the beautiful girl beneath me.

Her cute tits fell to the side, her large pink nipples and lovely hips enticing me as I watched her chest breathing rapidly, my hearing listening to her heart powerfully beating. “I am going to fuck you, and I won’t stop until one of us faints… Are you ready, Aki? My knot will swell, and you will be in pain… But I won’t stop.”

Aki’s beautiful eyes shone as she kissed me, “Fuck me, and knot me like your filthy bitch.” Her language was always so vulgar… but it was damn sexy!

My hips slammed against Aki, thrusting down while my cock bottomed out… her cunt moulding itself to my size, her pink labia surrounding me as she hugged me; her beautiful face showed ecstasy, no longer thinking about anything… only me and pleasure, and her body began to adapt to the brutal pounding, her breasts jiggling wildly, her eyes unfocused, and her cheeks blushed.

I could feel her shudder when I first pushed to her depths, but It no longer mattered; her body began to tremble, and it turned out my sister was a complete slut for Wolf Boys.

My hips pushed up… Aki cried as her virginal blood dripped down, a mixture of tears and drool coating her pretty face, an erotic spectacle that awakened my canine desires, causing me to begin a brutal assault against my sister’s tight pussy.

“Aki… AKI!” I called out, feeling her tight, warm passages gently cuddling my thick, meaty shaft like a loving mother.

“Haa…ah…nmnna….ahh….go…hge…..mmmmh!?”

She was speechless… the cute gasping moans leaving her swollen red lips.

Her juices ran down the bedsheets, a mixture of semen and feminine love juices, sticking to our bodies as my pubic hair stuck to my cute sister’s body… I was claiming Aki’s womb.

My canine instincts began to take over, my mind disappearing… a fog, and I focused on mating and mating, making her bear my offspring and showing that I was a superior male and that the weak me was gone! Only the stronger me deserved this top-class female!

With a strong slam, Aki let out a whimper; the force sent a shiver of excitement through her as I reached her womb, kissing her womb’s entrance, her pinkish hole twitching… her toes curled up.

“AKI.”

“BROTHER.”

We understood each other’s feelings… an unusual heat began to accumulate in my lower region, the pulsating knot expanding as the wolf side of my new species awoke… Aki’s pussy kept hugging me tightly, begging for seed as I hammered her cervix, my cock fighting against the pressure; finally, after four powerful slams, the gate opened, and the sticky, jelly-like musky sperm left my throbbing length directly into Aki’s waiting womb.

Like a dam bursting, I ejaculated nonstop… Aki’s womb filled in seconds, my sperm gushing through the cracks and covering her pink flesh walls… a burning sensation consumed me, the feeling that this wasn’t enough, that I needed to impregnate her.

So, my knot remained inside my sister, not wanting her warm insides to separate, locking us together, the knot pressing against the squirming hole, before it slipped inside, causing her virgin pussy to stretch beyond the perimeter of any male could compare, her soft walls now sealed as my sperm was locked inside her hot, fleshy tunnel.

With my cock blocked and ejecting the sticky baby paste into her unprotected depths.

“Brother…. ha… it’s so hot…. and full…. your sperm is flooding my uterus…!” Aki wasn’t tired; rather, her eyes were bright as her insides began to slither around my cock like a slimy snake. “More… make my belly swell with your babies?” her arms spread out as she hugged me tightly, wrapping herself around my back with her legs.

What else could I do but answer her desire?

Because we were locked together, I could only push my hips with more force, the tip of my cock crushing her womb while swaying and twisting my hips to let my glans pull on her soft, sticky folds, causing my cute sister to moan in pleasure.

“Haa… ‘m there…. keep moving…. fast..ahhh….mmmph~~!!” Aki couldn’t utter complete sentences anymore, a slave to her desires… my canine instinct dominated her entirely; the rough fuck session had caused the bulging veins and knotted canine cock to mark her insides, changing them…

I felt another load of sperm spurting from my tip into her depths, nothing like a normal human, as my hips pounded her soft pale body, slapping her ass against my thighs as she gasped from the force of each thrust.

Aki trembled; the overflowing cum reached my knot, mixing with her love juices, creating a slick frothy mixture, creating an obscene sound as my pelvis rubbed her clit with each rough movement… the viscous, slippery liquid flowing down her inner thighs from the slight gap as I moved my cock, her sweaty and trembling body becoming tense.

“Nnnn… deep…hot…..”

Her wet skin glistened under the faint light, her black hair messy as it plastered to her skin.

Her half-opened almond irises, trying to focus, her cute small fangs biting her lower lip, and a thin trail of saliva escaped the corner of her red and abused lips.

An addictive sight… something I never imagined happening; Aki’s moans became a cry of pure lust and ecstasy… she came, arching her hips while hugging my hips.

With no escape… My canine cock unleashed more virile baby paste, a copious load for a normal human, covering every nook and cranny, forcing the sticky semen to flow through the gaps and drip down the corners of her pink insides, my sister’s womb swelling slightly, distending her abdomen.

A lewd scene… my wolf side completely dominating her as my instincts caused my body to want more of Aki.

Aki and I could no longer speak… only the sounds of the sticky, slimy frothy liquid escaping her stuffed insides with each move and our rough and erratic breaths.

Our orgasms didn’t end; multiple waves flooded my sister’s pink honeycomb… the hot and sticky cream continuously filling her and exiting, flowing and dripping like an eruption from her filled insides.

“Huff… Aki!! Cum….keep cumming….”

We were no longer brother and sister but beasts craving pleasure, two young people fucking and lost in their primal desire.

Like this, we continued until the sun began to rise, her lips swollen from our aggressive kissing, my teeth marking her breasts and body with their sharp marks and bruises from the love bites, while her stomach was swollen, as finally, my cock began to calm, her insides like a small ocean of sperm.

With one last burst of energy, I pistoned my sister’s divine pussy.

Each violent thrust brought Aki closer to yet another orgasm; her body was young, and even though my canine nature dominated, the stamina increase made me fuck her without stopping… her moaning getting weaker and her grip on me weaker… until Aki passed out.

My cock finally retracted, separating the sticky fluids as her womb’s gate tried to keep my precious milk inside, her insides rejecting it… A large white thick, milky mixture flowed from her swollen and abused hole like a flash flood; her bed was stained and became sloppy.

“Love you, Aki.” With a groan, I cleaned my dirty cock with her raven-coloured locks.

With what little consciousness I had, I wrapped Aki in clean sheets… carrying her, not worried about being discovered, and dropped her on my clean bed and fell exhausted beside her, kissing her softly as the wolf nature caused my instincts to leave a weak mark.

“Love you…” These were my final words before exhaustion overpowered me… the fatigue of my new race was amazing; the pleasure and rough fuck session had emptied me.
