The air in my bedroom was thick, heavy with the scent of our shared arousal and the unspoken promises that had been simmering between Emily and me for what felt like an eternity. The world outside the door, with its complicated web of family and heritage, ceased to exist. There was only the dim light from the bedside lamp, painting our shadows across the walls in a frenetic dance, and the thunderous beat of my own heart crashing against my ribs. Emily's eyes, wide and dark with a desperate hunger, were locked on mine. Her fingers, delicate but insistent, guided my hand from the warm, sweat-slicked skin of her stomach, down past the delicate ridge of her hip bone, through the soft, damp curls, until my fingertips met the scorching, liquid heat of her very core.
A sharp, shuddering gasp escaped her lips, a sound so raw it was almost a sob.
"Brother…" she whispered, the word not a title of familial bond but a sultry, forbidden incantation on her breath.
"I want you…. I want you to fuck me… Please~" It was low, husky, dripping with a need that vibrated through my entire being.
Her face was a masterpiece of flushed desire, cheeks painted a deep, feverish crimson. The elegant line of her neck was arched, her perfect lips parted and glistening. She was begging, and the sight of my proud, typically composed American sister reduced to such a state of vulnerable, aching need sent a primal surge of power straight to my already throbbing cock. I held her gaze, my own voice dropping to a low, possessive growl that seemed to resonate from deep within my chest.
"Emily… Sis… if we do this," I stated, each word measured and heavy with intent, "There is no going back... You do understand that, right? You will not just be my sister, anymore... You will be mine. My bitch. My wife. My partner in everything. I do not share what is mine... I am a really possessive man… Is that what you truly want? To belong to me, completely?".
Her answer was immediate, her eyes flashing with a fire that mirrored my own.
"Yes!! More than anything... More than being just your sister... I want to be yours... I want to be your slutty little bitch..." Her voice was a fervent pledge, a vow sealed not in a church, but in the humid, charged space between our bodies.
That was all the confirmation I needed. The last thread of my restraint snapped. In one fluid, frantic motion, I undressed, my clothes becoming nothing but obstacles to be discarded onto the floor in a heap. The cool air of the room did nothing to quell the fire raging under my skin.
I laid back on the bed, the sheets cool against my back, my cock standing tall and rigid, a thick, veined testament to the desire she had stoked into an inferno. Emily's eyes widened, her gaze dropping and instantly gluing itself to my erection.
"Oh… wow…" A soft, awed whispered past her lips. Her hunger was a palpable force, and it was the most potent aphrodisiac I had ever known.
"Emily," I commanded, my voice rough with need. "Come here… Lil Sis… Suck my cock."
Her response was a breathy, obedient sigh. "Yes, brother."
She moved with an eagerness that was breathtaking, crawling up the bed until she was positioned between my legs, her beautiful face level with my aching hardness. She didn't hesitate. Her small, soft hands wrapped around the base of my shaft, her touch sending electric jolts through me.
"Schlup. Schlup...♥Slurp! mm, mmm~" Her lips, so full and perfect, parted and she took the broad, weeping head into her mouth.
"Ohhhh… fuck." The warmth and wetness were instantaneous, an exquisite torture.
"Mh, mmh… Sllurp. Sllluuurp… Lick…♥Suck~" Her tongue swirled around the crown, lapping at the pre-cum that had already beaded there, tasting me with a soft, appreciative moan that vibrated directly through my cock and into my spine.
"Schlup. Schlluuup... Guk!! GUHUK!!! AUURRHHHH~" Then, she began to descend, taking more and more of me into the hot, velvety depths of her mouth. Her cheeks hollowed dramatically as she applied a vacuum-like suction that made my toes curl and my hips buck involuntarily.
"Slurp... Shlllp... Gllck… Slluurrpp~ Guh~" The obscene, wet sounds of her worship filled the room, a symphony dedicated to my pleasure. Her head bobbed with a furious, desperate rhythm, her eyes—glazed with lust—looking up at me to gauge my reaction.
"Ahhhh~ Do you like my mouth, brother?" she asked, her words slightly muffled around my girth, a string of saliva connecting her lip to my shaft. "Do you like how I suck your big cock?"
"Yes, Lil sis… God's your mouth is heaven," I groaned, my hands tangling in her soft hair.
Seemingly inspired, she pulled off with a loud, wet POP! and instead, pushed her generous breasts together, creating a deep, soft valley of flawless skin. She guided my throbbing cock between them, the sight of my engorged flesh disappearing and reappearing between her pale orbs utterly surreal.
"Pap~ Your cock is so big and long, brother," she breathed, her voice full of awe as she moved her breasts up and down the length of my shaft while simultaneously leaning down to lick and suck at the head that poked out from the top with each upward motion.
"Mmmph… see? It's too big… it even pokes out of my big breasts...Pap! Pap! Pap!... Hmm, fuck, you cock is so hot, big bro~ Hmm~ SSlllrrpppp~ Lick…♥ Suck, suck,". The dual sensation—the soft, pillowy pressure of her tits and the hot, wet suction of her mouth—was pushing me rapidly towards the edge.
My breath came in ragged gasps. "Emily… I'm close…".
She increased her pace, her breasts sandwiching my cock harder, her mouth working me over with relentless enthusiasm.
"Hmm! Pap! Sllllrrrpppp!!! Cum in my mouth, brother," she pleaded, her voice a desperate chant. "Please~ Sllllrrrpppp~, I want to taste it… Give it all to me.".
I could feel the tension coiling at the base of my spine, a dam about to break. With a guttural roar, I grabbed her head firmly, not forcing, but guiding, and pushed my hips up off the bed, driving myself deeper. The top five inches of my cock slid past her lips and hit the back of her throat.
"Guk!! GUHUK!!! COUGH! Schlup. Schlup...♥Guk!!" She gagged softly but took it, her eyes watering as she looked up at me with utter submission.
That look undid me completely. With a final, shuddering thrust, I erupted. Rope after thick, hot rope of cum shot down her throat.
"Gush. Splurt. Splurt…. Spurt! Spurt… SSpppurrrtt! …Gulp! Gulp!!" She gulped hard, her throat working frantically to swallow the overwhelming torrent, a few stray drops escaping and tracing white lines down her chin.
I pulsed and throbbed in her mouth for what felt like an eternity, my entire body convulsing with the force of my release. When I finally collapsed back onto the bed, spent, she slowly pulled off, making sure to lick me clean with a delicate swipe of her tongue. She looked up at me, a blissful, messy smile on her beautiful face.
"Gulp! Gulp!! Ahhh…" she sighed, licking her lips. "Ahhh~ I ate everything, brother…. Hmmm~ your cum is so delicious…".
The sight of her, face glazed with my essence and beaming with pride, reignited a deep, possessive hunger in me. The taste of me on her lips was just the beginning. I needed to claim the rest of her.
"Turn over," I ordered, my voice already regaining its dark, commanding edge. "On your hands and knees...".
"Yes, brother," she panted, immediately obeying. She moved with a new, sultry grace, turning and presenting herself to me, her back arched dramatically, pushing her round, voluminous ass high into the air. It was an offering, a plea, and a challenge all at once.
"God, you got a perfect pale ass, Emily… perfect, so fucking…" I raised my hand and brought it down hard on the perfect, pale curve of her left cheek.
"PAH! PAH! PAH! Fucking perfect," The sound was sharp, a gunshot in the quiet room, immediately followed by the bloom of a red handprint on her skin.
"Shit,… I love your giant, juicy ass, Lil Sis," I growled, kneading the stinging flesh.
"Ahhnn~ I know you loved it, Bro— PAH!" she started to say, but I cut her off with another sharp slap on the opposite cheek.
My fingers trailed down the cleft of her ass, through her slick folds. She was dripping, her arousal coating my fingers instantly.
"Goddamn, you are wet, Emily," I muttered, my own cock, already hard again, twitching at the sensation.
"I'm so horny for you, brother," she begged, pushing her hips back against my hand. "Please, fuck me…. fuck my slutty wet pussy please~".
I positioned myself behind her, the head of my thick, renewed cock pressing against her dripping entrance. I leaned forward, my voice a low, dominant whisper in her ear.
"From now on, Emily, this…" I pressed inward slightly, making her gasp. "…this wet, tight, perfect little pussy… is my pussy!" With my final declaration, I slammed my hips forward, PAH!, burying every single inch of my 11.5-inch length into her in one brutal, claiming thrust.
Her reaction was instantaneous and explosive. "AAAAHHHHH!!! YES, BROTHER!" she screamed, her back bowing violently.
"It's yours! It's yours!!! It's big brother's pussy! Ughhhh!!! Ahnnn!!! FUCKKK!!! YOUR COCK IS TOO FUCKING BIGGG! AHHHNNNNN!!!!!".
"That, right Slut! Hmm! Fuck your pussy is tight as fuck!". She was impossibly tight, her inner muscles clenching and fluttering around me like a silken fist, trying to accommodate my overwhelming girth. I began to move, setting a punishing, animalistic rhythm.
"SMACK! SMACK! SMACK!" The sound of our bodies meeting, of my hips pounding into her willing flesh, echoed around us, punctuated by our ragged breaths and her sharp, pleasure-filled cries.
"Fuck! You're so fucking tight, Emily!" I grunted, each thrust a battle against the exquisite, crushing pressure of her cunt.
"Ahnnn!!! …Brother! …Ahnnn!!! …I'm cumming! …Ahnnn!!!" she shrieked, her voice cracking with the intensity of it. Her inner walls suddenly clamped down on my cock with a vicious, rhythmic strength, milking me, pulling me deeper.
"Ahnnn!!! My pussy's… ahh… getting split open… Your cock's so big and... thick… Ngh♥ Ughh♥Ooooohhhhhh! Ooh! IM CUMMING!!! Spurt! Spurt… SSpppurrrtt!" A hot gush of her release flooded around my shaft, drenching my balls and the sheets beneath us with her essence.
Her climax triggered my own. My rhythm broke into a frantic, shallow pounding.
"Pah! Pah! Pah! …FUCK, EMILY! I'M CUMMING TOO!!" I roared, driving into her one last, final time, burying myself to the hilt, my pelvis grinding against her swollen, sensitive flesh. The feeling was unimaginable.
"Brother! Too deep! Too deep! AHHNNN!!!! FUUCCCCKK~~~" she wailed, her body trembling uncontrollably.
"FUCKK!! Brother! Ahnn!! Too Deep!!!!! You're in my womb!!! AAAAHHHHH!!! Ooooohhhhhh! Ooh! … SSpppurrrtt! SSpppurrrtt! SSpppurrrtt!" Her scream was a beautiful mix of searing pain and transcendent pleasure as I erupted inside her, pump after powerful pump of my seed flooding her deepest depths, marking her, claiming her, fulfilling the promise I had made.
"Hah! Hah! Hah! SLAP!!". I palmed her juicy red ass, as we collapsed together, a tangled, sweaty, spent heap, bound together now by something far stronger and more primal than blood. She was mine.
"…Hah~ I love your big cock, big bro…". Emily muttered with her face masked with red haze and sweat; her blonde hair sticks to her skin.
"And I love, your tight pussy, Em…It was made for me like a mold…". I replied to her, as i pinched her nipple.
"Pft… of course it made to fit yours… we come from the same factory after all…". Emily smiled and laughs, she managed to make me smile as well. fuck I love this world, where Incest joke was just peak tier comedy.
