The house was dead quiet after midnight, just the hum of the fridge and the occasional creak of old floorboards. I had come home from college for the weekend, and so had my brother Jake. We were both twenty-two now, adults who knew better, but old habits die hard. We ended up on the couch together, half-watching some dumb movie, sharing a bottle of whiskey we had swiped from Dads cabinet.
Jake sat close. Too close. His thigh pressed against mine, and every time he laughed at the screen his hand brushed my knee. I was wearing nothing but an old tank top and cotton panties, and the heat from his body made my skin prickle. We had always been touchy, but tonight the whiskey loosened everything.
Remember when we used to wrestle for the remote? he said, voice low.
I smirked. You always pinned me. Cheater.
He set the bottle down and grabbed me, playful at first. I shoved back, laughing, and suddenly we were rolling on the couch, his strong arms around me, my legs kicking. His body was bigger than I remembered, all hard muscle from the gym. My tank top rode up. His hand landed on my bare stomach, then slid lower when I twisted.
Fuck, stop squirming, he growled, but he didnt let go.
My ass pressed back against him and I felt ithis cock, thick and already half-hard in his sweatpants. It nudged right between my cheeks. I froze for a second, heart hammering. He didnt pull away. Instead he rolled his hips once, slow, testing.
Jake I whispered.
He didnt answer with words. His hand moved down, fingers hooking the edge of my panties and yanking them aside. Cool air hit my pussy. I was wet already, shamefully so. His fingers brushed my slit, parting my lips, and a low groan left his throat.
Jesus, youre soaked.
I should have stopped him. Instead I pushed back harder, grinding my ass against that fat bulge. His cock slipped free when he shoved his pants down just enough. Hot, heavy, the head nudging my entrance from behind. We were both breathing hard. The movie kept playing, forgotten.
One thrust and he was inside me.
No warning. His cock just slipped right in, stretching my tight pussy in one long, thick slide. I gasped, nails digging into the couch cushion. He bottomed out, balls pressed tight to my clit, and stayed there, letting me feel every inch.
Fuck, sis, he muttered, voice rough. Youre gripping me so good.
He started moving. Short, hard strokes at first, then longer ones that dragged his cock almost all the way out before slamming back in. The wet sound of my pussy taking him filled the room. I reached back, grabbed his hip, and pulled him deeper.
Harder, I hissed. Dont you dare go easy on me.
Jake fucked like he had been waiting years for this. He flipped me onto my back, yanked my legs over his shoulders, and drove in again. My tank top was shoved up over my tits; he leaned down and sucked a nipple into his mouth while his cock pounded me. Every thrust made my clit throb. I could feel myself getting slicker, coating his shaft.
He pulled out suddenly, flipped me again, and hauled my ass up. Doggy style on the couch. His cock slid back inside with a filthy squelch. One hand fisted my hair, the other slapped my ass hard enough to sting.
Look at you, he said, voice dirty and direct. Taking your brothers cock like a little slut. You love it, dont you?
Yes, I moaned. God, yes. Fill me up.
He reached under me, rubbed my clit in fast circles while he fucked me deep. My orgasm hit fast and mean. My pussy clenched around him, pulsing, and I cried out into the cushion. Jake didnt stop. He kept pounding through it, chasing his own release.
When he came he buried himself to the hilt and growled my name. Hot spurts flooded my pussy, thick and endless. Some leaked out around his cock, dripping down my thighs. He stayed inside me, rocking gently as the last pulses faded.
We didnt move for a long minute. His cock softened slowly, still nestled in my cum-filled cunt. Finally he pulled out with a wet sound and flopped beside me. I turned, legs shaky, and looked at him.
Again? I asked.
His answer was a grin and another hard kiss. We spent the rest of the night on that couch, his cock slipping back inside me every time it got hard again. No guilt, just raw need. By morning we both knew this was only the start.
We cleaned up before anyone else woke, but the secret sat between us like a live wire. Every look, every accidental touch after that carried the memory of how easily his cock had slid into his sister and how fucking good it felt. We kept finding reasons to be alone. Showers. Late-night drives. The guest room when the house was full.
Each time the same hunger hit. His hands on my hips, my panties shoved aside, that thick cock pushing deep with one smooth thrust. I learned how he liked itfast and rough, balls slapping my clit, my name growled in my ear. He learned how fast I came when he talked dirty, telling me exactly what a filthy sister I was for milking his cock.
One afternoon in the garage, door half-open, he bent me over the hood of his car. Oil stained my knees. His cock slipped inside me from behind while the neighbor mowed his lawn twenty feet away. I bit my arm to stay quiet while he pumped load after load into me. We didnt stop until my pussy was overflowing and his legs shook.
It never got less intense. The forbidden edge only sharpened everything. When he slid into me now it felt inevitable, like my body had always been waiting for his cock to claim it. We didnt need excuses anymore. We just took what we wanted.
And every single time, it felt even better than the first accidental slip.
