I walked into the kitchen that night and there he was, my older brother Jake, leaning against the counter in nothing but gray sweatpants. The bulge was fucking obscene, thick and heavy, stretching the fabric like it was about to rip. We'd both turned eighteen years ago, but living together after college had turned every glance into something filthy.
"Stop staring at my dick, sis," he said, voice low and rough. His hand rubbed over the outline, slow and deliberate. "You keep looking like that and I'm gonna do something about it."
My pussy clenched instantly. "Maybe I want you to," I shot back, stepping closer. My tank top barely covered my tits, nipples already hard.
Jake didn't hesitate.
He shoved his pants down and that big dick sprang free, veined, thick as my wrist, the head already leaking. "On your knees then. Suck your brother's big cock."
I dropped fast, wrapping both hands around the shaft. It was so fucking huge my fingers didn't meet. I licked the head first, tasting salt and heat, then opened wide and pushed him into my mouth. My jaw ached right away but I didn't stop. I bobbed hard, spit running down his balls while I gagged on the length.
"Fuck yes, take it deeper," he growled, grabbing my hair and thrusting. "That's it, little sister. Choke on this dick like you've been wanting to."
I moaned around him, one hand between my legs rubbing my soaked panties. He pulled out with a wet pop and hauled me up, spinning me around. Bent over the counter, he yanked my shorts and panties down in one move.
"Look at this wet cunt," he muttered, slapping his fat cock against my ass. "Beg for it."
"Put that big dick in me, Jake. Fuck your sister. I need it."
He lined up and shoved in hard. The stretch burned so good I cried out. Inch after thick inch forced my pussy open until his hips slapped my ass. He didn't go slow. He pounded me, balls deep every thrust, the wet sound of my cunt taking him filling the room.
"Goddamn, you're tight," he grunted, one hand reaching around to rub my clit. "This pussy was made for my cock."
I pushed back, meeting every slam. "Harder. Wreck me with that huge dick."
He did. He fucked me like he owned me, deep and brutal, until my legs shook. When I came I screamed his name, pussy pulsing around him. He kept going, using my orgasm to drive deeper.
Then he pulled out, flipped me onto the table, and shoved back in missionary. My legs over his shoulders, that massive cock spearing me open again. Sweat dripped off him onto my tits. I reached down to feel where we joined, fingers circling his thick shaft as it disappeared inside me.
"Fill me up," I begged. "Cum in your sister's cunt."
Jake slammed in one last time and unloaded, hot jets flooding me. He kept thrusting through it, pushing his load deeper until it leaked out around his cock.
We didn't stop there. Later in his bed he had me ride him, that big dick stretching me from below while I ground my clit against him. Then he bent me over the headboard and took my ass, working that monster in slow until I was sobbing from the mix of pain and pleasure.
By morning I was sore, covered in his cum, and already hungry for more. Jake's big dick had turned our house into one long, filthy secret we both wanted to keep.
