We were both adults when it started, me twenty-three and my sister twenty-one, living in the same apartment after our parents moved away. One night she came into my room holding her phone, the screen glowing with some cheap audio file labeled brother sister incest sex stories audio. "You gotta hear this," she said, her voice already low and rough. She hit play and the dirty narration filled the room: a guy describing fucking his sister raw, pounding her tight pussy while she begged for more.
I felt my cock twitch immediately. She noticed. "You like that shit?" she asked, grinning dirty. I didn't answer with words. I grabbed her wrist and pulled her onto the bed. The audio kept playing, the voice growling about sliding into forbidden cunt, and we started making our own sounds to match it.
She stripped fast, yanking off her tank top so her full tits bounced free. I shoved my hand between her legs and found her already soaked through her panties. "Fuck, you're dripping just from that audio," I muttered, pushing two fingers inside her. She moaned loud, grinding down on my hand while the recording kept talking about brother cock stretching sister holes.
We didn't waste time. I ripped her panties off and buried my face between her thighs, licking her clit hard and fast the way the audio voice described. She tasted sweet and dirty at the same time. Her fingers tangled in my hair, holding me there while she came the first time, hips bucking against my tongue.
Then she pushed me back, unzipped me, and pulled my thick cock out. "Bigger than the guy in the story," she said, wrapping her lips around the head and sucking deep. The audio kept going in the background, voices describing sloppy incest blowjobs, and she matched every filthy detail. She gagged on me, spit running down my shaft, eyes watering but never stopping.
When I couldn't take it anymore I flipped her onto her hands and knees. The audio was at the part about doggy-style sibling fucking. I slammed into her wet pussy in one thrust. She cried out, pushing back to take every inch. "Harder, like the story," she panted. I fucked her rough, skin slapping loud, her ass jiggling with every drive. The audio voice narrated right along with us, talking about filling sister pussy with brother cum.
She came again, clenching tight around my cock, and I didn't pull out. I unloaded deep inside her, pulse after pulse, while the recording kept playing. We stayed locked together, breathing hard, listening to the end of the audio story about secret sibling creampies.
After that night we started recording our own sessions. She set her phone up and we'd play the original audio in the background for inspiration. One time she rode me reverse cowgirl, bouncing on my dick while describing everything out loud for the mic: how her brother's cock felt stretching her, how she loved the wet sounds of incest sex. Another night I bent her over the kitchen counter, the audio playing from the living room, and fucked her ass for the first time while she begged just like the story.
We got addicted to it. Every new brother sister incest sex stories audio she found became foreplay. We'd listen together, get worked up, then act out the dirtiest parts. She loved when I talked dirty back, calling her my slutty sister, telling her how good her forbidden pussy felt. I loved the way she came harder when the audio described breeding, so I started pumping loads into her every time.
Months later we had a whole folder of our own recordings. We'd listen to them on nights we couldn't fuck, her fingering herself while I stroked, both of us getting off to the sounds of our own raw, nasty sibling sex. It never got old. The taboo stayed hot because we kept it secret, kept it filthy, and always had that original audio playing to remind us exactly how wrong and perfect it felt.
We still do it.
Every time a new brother sister incest sex stories audio pops up online, we download it, press play, and make it real all over again.
