He dipped his head and sucked one nipple deep into his scalding mouth. Teeth scraped, tongue lashed, wet suction noises filled the room. His free hand slapped my other tit sharp and stinging, watched it jiggle and redden before he mauled it again, kneaded like he couldn’t get enough. I arched into him, thighs clenched, already soaked through my shorts.
He pulled off with a wet pop, blew cold air over the aching bud, then attacked the other one just as viciously. My knees nearly buckled.
“Jake.” It came out a broken moan.
He spun me fast, slammed my front to the door. My bare tits squished against the wood, nipples dragged with every breath. Shorts and panties dragged down my thighs in one savage yank, pooled at my ankles. Cool air kissed my dripping pussy right before his huge palm cracked across my ass once, twice, three times in rapid succession.
The sting exploded into heat. I cried out.
“Count them, little sister,” he ordered, voice dark and thick.
Smack.
“One, fuck.”
Smack. Harder, right on the same spot.
“Two, Jake...”
By seven my ass was glowing cherry-red, thighs trembled, slick ran in rivulets down the inside of my legs. He ground against me from behind, still in his shorts, the obscene ridge of his cock dragged over my burning skin. Dry humped me like a rutting animal, hips rolled slow and filthy, let me feel every thick inch he was about to ruin me with.
“Feel that?” He fisted my hair, yanked my head back until my spine arched painfully. His other hand wrapped around my throat firm, possessive, thumb pressed just under my jaw. “Feel how fucking hard your own stepbrother is for you?”
He squeezed, cut off air for a heartbeat. My pulse thundered in my ears, cunt clenched on nothing. Then he let go and I sucked in a desperate breath, dizzy and dripping.
He kicked my feet wider. His shorts dropped. That monster cock slapped heavy against my sore ass scalding, veined, already leaked precum in fat beads. He dragged the swollen head through my sloppy folds, coated himself, nudged my clit until I was humping back against him shamelessly.
“Jake, please.”
“Please what, baby sis?”
“Fuck me. Shove that big brother cock inside me. I need it.”
He snarled, lined up, and thrust balls-deep in one brutal stroke.
I screamed. The stretch was obscene, burned, perfect, too much and not enough. He bottomed out, hips flush to my burning ass, and held there, let me feel every pulsing inch.
“So goddamn tight,” he groaned. “Like this greedy little pussy was made to milk its own brother.”
He pulled back slow, dragged over every nerve, then slammed home again. The door rattled in its frame. Again. Again. Harder, faster, until my tits were smacking the wood with every thrust and the only sounds were wet slaps, my broken moans, and his filthy praise.
His hand left my hair to snake around and choke me again tighter this time, owned my breath while his other rubbed brutal circles over my clit. I came without warning, squirted down my thighs, walls clamped around him so hard he cursed.
He didn’t stop. Fucked me right through it until I was sobbing from overstimulation.
Then he pulled out, spun me, and shoved me to my knees.
“Open that pretty mouth.”
His cock glistened with my cream and shoved past my lips before I could breathe. He fucked my face hard, hips snapped, balls slapped my chin. Drool poured down my chin, mixed with tears and mascara. I gagged, throat convulsed around the head, but sucked harder, hollowed my cheeks, desperate to taste him.
“Fuck yes, choke on your brother’s dick, Lily.” He held my head and pistoned until my jaw ached, then yanked out with a wet pop, strings of spit connected us.
He hauled me up, threw me on the bed like I weighed nothing. Before I could scramble, his head was between my thighs, tongue speared deep, lapped up the mess we’d made like he was starving. Two thick fingers shoved in alongside, curled hard, pounded my g-spot while he sucked my clit so viciously I saw stars.
I came again instantly, ground against his face, screamed into the pillow as he drank every drop.
He flipped me onto my stomach, yanked my hips up until I was on all fours. Another round of merciless spanks ten, fifteen, I lost count until my ass was throbbing and I was begging incoherently. Then he mounted me, cock drove so deep I felt him in my throat.
One hand fisted my hair, arched my back. The other choked me from the front now, fingers dug into the sides of my neck, controlled every breath while he railed me raw.
“Whose pussy is this, Lily?”
“Y-yours, fuck, your sister’s sloppy little cunt.”
He roared, slammed home one last time, flooded me with thick, hot ropes of cum. I felt every pulse, felt it leak out around him as he kept lazily thrusting through the mess
But he wasn’t finished.
He rolled us, pulled me on top. “Ride me. Show big brother how much you love this taboo shit.”
I sank down with a broken moan, took him to the root. His hands gripped my sore ass, spread me wide while I bounced, tits jiggled wildly. He slapped them, pinched my nipples, choked me lightly as I chased another orgasm.
Reverse cowgirl with his thumb teased my ass, threatened to push in. Doggy again, hair pulled so tight my scalp burned, his palm printed my skin red. Slow, filthy missionary where he kissed me deep and tender even as he choked me and whispered about breeding his own stepsister until I came just from the words.
By the fifth round we were wrecked. Sheets ruined, bodies slick with sweat and cum, bite marks and handprints bloomed everywhere. He had me on my side, one leg hitched over his hip, cock buried deep, rocked lazy and possessive while he sucked dark bruises into my tits and throat.
His phone buzzed on the nightstand. His friend: “You hit that yet bro??”
Jake didn’t even look away from my eyes. He reached over, deleted the message, and tossed the phone across the room. It clattered to the floor.
He rolled on top of me again, slid home effortlessly into the mess between my thighs.
“Lock the door, sis,” he murmured against my swollen lips.
My arm trembled as I reached back and clicked it shut.
His grin was pure sin, eyes already darkened again.
“Good girl. Spread those legs wide. Big brother’s keeping you full till sunrise, and every fucking night this summer.”
He thrust deep, swallowed my moan with a kiss that tasted like salt, cum, and the most forbidden kind of desire.
