I never planned to fuck my brother. But the night it happened, the air in our parents' old house felt thick with everything we'd both been pretending wasn't there for years. I was twenty-two, home from college for the summer, and Jake was twenty-four, just out of the army. We were alone because Mom and Dad had taken the RV to the coast. The house creaked like it always did, but tonight every sound seemed to point straight at the two of us.
Jake had always been the quiet one, built like a wall from years of lifting and drills. I was the mouthy little sister who used to steal his hoodies and wear them to bed. That night I walked downstairs in nothing but one of those same hoodies and a pair of tiny cotton panties, still damp from the shower. He was on the couch in just gym shorts, scrolling his phone, the blue light cutting across his chest.
"You gonna sit or just stand there staring?" he asked without looking up.
I dropped onto the cushion beside him, legs tucked under me. The hoodie rode high on my thighs. "You always this charming when you're alone?"
He finally glanced over. His eyes dropped for half a second too long. "You're not a kid anymore, Amber."
"Never said I was." I shifted so my knee brushed his. Heat jumped between us like a live wire. "You keep looking at me like that and I'm gonna think you want something."
Jake set the phone down. "Don't start shit you can't finish."
I leaned in until my breath hit his ear. "Who said I can't finish it?"
His hand landed on my thigh, rough palm sliding under the hem of the hoodie. Fingers traced the edge of my panties and I felt myself get wet instantly. No slow burn, no pretending. I grabbed his wrist and pushed his hand higher until his fingertips pressed against the damp cotton.
"Fuck," he muttered. Two fingers rubbed me through the fabric, slow and deliberate. "You're soaked already."
"Been thinking about this since I got home." I reached into his shorts and wrapped my hand around his cock. Thick, already hard, hot against my palm. I stroked him once, twice, feeling him twitch. "Big brother dick feels even better than I imagined."
Jake yanked my panties aside and shoved two fingers straight into me. No teasing, just deep and rough. I moaned loud enough to echo off the walls. He finger-fucked me hard on that couch while I jerked him off, both of us breathing like we'd run a mile.
"Get these off," he growled, tugging at the hoodie. I pulled it over my head. My tits bounced free and he leaned in, sucking one nipple hard while his fingers kept pumping. I came on his hand right there, thighs shaking, juices running down his wrist.
He didn't give me time to recover. Jake stood, shoved his shorts down, and pulled me up by the hair. "On your knees."
I dropped. His cock slapped my cheek, thick and veined. I opened my mouth and took him deep, gagging on the first thrust. He held my head and fucked my throat, spit dripping down my chin onto my tits. I looked up at him while I sucked, eyes watering, loving every second of it.
"Jesus, Amber. That mouth…" He pulled out, hauled me to my feet, and bent me over the arm of the couch. One hard yank and my panties were around my ankles. He kicked my legs apart and slammed into me from behind in one thrust.
I screamed. He was bigger than any guy I'd had at school. My pussy stretched around him, clenching tight. Jake grabbed my hips and pounded me, skin slapping loud and filthy. Every stroke hit deep, making my ass jiggle and my tits swing.
"Harder," I begged. "Fuck your sister harder."
He reached around and rubbed my clit while he railed me. I came again, pussy pulsing around his cock. Jake didn't stop. He flipped me onto my back on the couch, hooked my legs over his shoulders, and drove back in. The new angle made me see stars. I clawed at his back, leaving red lines while he fucked me like he hated me and loved me at the same time.
Sweat slicked our bodies. The couch creaked under us. He pulled out just long enough to flip me again, this time on all fours, and shoved back inside. His thumb pressed against my asshole, teasing, then pushing in. Double penetration with just his cock and finger had me wailing.
"Gonna fill you up," he grunted. "You want your brother's cum?"
"Yes—fuck yes. Breed me."
Jake slammed in deep and came with a roar, hot spurts flooding my pussy. I felt every pulse. He kept thrusting through it, pushing his load deeper until it leaked out around his shaft.
We didn't stop there. He carried me upstairs to his old room, threw me on the bed, and ate me out until I came on his tongue, tasting his own cum mixed with mine. Then I rode him, grinding my clit against his pelvis while he sucked my tits. We fucked until the sun came up—missionary, doggy, me on top, him holding me against the wall. By morning my thighs were bruised, my throat raw, and my pussy sore in the best way.
We showered together, soaping each other up and going at it again under the spray. After that night we never talked about stopping. Every time our parents left, we used the house like it was ours. Raw, messy, no apologies. Just Amber and Jake, finally giving in to what we'd both wanted for years.
It wasn't romantic. It was dirty and real and exactly what we needed. And neither of us planned on quitting anytime soon.
