I got hooked on audio incest sex stories the second I heard that first recording. Some chick moaning into a mic, pretending to be a little sister begging her big brother to stuff her pussy full. "Fuck me harder, bro, fill my cunt," she panted, voice all breathy and desperate. I had my cock in my fist in seconds, stroking rough and fast while the sounds of fake skin slapping and wet sucking filled my headphones. Those stories always hit different. The taboo filth of it, the way the voices got raw and nasty, made my balls ache.
One night I decided to make my own. My sister Rachel was home from college, eighteen and always walking around in those tiny shorts that hugged her ass. We were close, real close, the kind of close where we'd joke about dirty shit after a few beers. I told her about the audio incest sex stories I listened to. She laughed at first, then her cheeks went pink. "You really jerk off to that brother-sister crap?" she asked, biting her lip. I nodded and told her straight: "Yeah, and I want to record one with you."
She didn't say no. Instead she leaned in and whispered, "Let's do it for real." We set up the mic in her bedroom that night. Rachel stripped down to nothing but a thin tank top, nipples hard and poking through. I hit record and started talking dirty right away. "Tell them how bad you want your brother's cock, sis." She spread her legs on the bed, fingers sliding over her shaved pussy. "I want it so fucking bad," she moaned into the mic. "I want my brother to shove his thick dick in my tight hole and pound me till I scream."
The recording picked up every wet sound as she fingered herself. I pulled my cock out, already leaking, and climbed between her thighs. "Say it louder," I growled, rubbing the head against her slick folds. "Tell the listeners you're about to get fucked by your own brother." Rachel's voice cracked with lust. "Please, bro, fuck your little sister's pussy. Stretch me open." I slammed in deep on the first thrust, burying every inch in her hot, gripping cunt. She cried out, the mic catching the slap of my balls against her ass and the filthy squelch of her juices.
We kept the dirty talk going for the audio.
"You like that incest cock, don't you?" I grunted, pounding her hard and steady. Rachel arched her back, tits bouncing. "Yes, fuck yes, give it to me. Cum in my pussy like a real brother would." The bed creaked under us, skin slapping loud and raw. I reached down and rubbed her clit while I fucked her, making her moan even filthier into the mic. "I'm gonna cum on my brother's dick," she gasped, voice shaking. Her walls clenched tight, pulsing around me as she came hard, soaking the sheets.
I flipped her onto her hands and knees and kept recording. "Listen to this, all you pervs," I said into the mic, voice low and nasty. "My sister's asshole is winking at me while I wreck her cunt from behind." I drove in deeper, gripping her hips, watching my cock disappear into her again and again. Rachel pushed back, meeting every thrust. "Harder, bro. Make me your incest slut." The audio caught her whimpers turning into full-on screams when I reached around and pinched her nipples. Sweat dripped down her back, her pussy gripping me like it never wanted to let go.
We kept going until my balls drew up tight. "Gonna fill you up," I warned, voice rough. Rachel begged into the mic, "Cum inside me, brother. Breed your sister's cunt." I slammed home one last time and exploded, shooting thick ropes of cum deep in her spasming hole. She milked every drop, the wet sounds of my load mixing with her juices loud on the recording. We stayed locked together, breathing heavy, the mic still running as my cum started to leak out around my softening cock.
Later we listened to the finished audio together. Rachel's hand was already in my lap, stroking me back to full hardness while the sounds of our own incest fuck played back. "We should make more," she said, voice husky. I nodded and pulled her onto my lap again. The next recording started right there, her riding me slow and deep while she whispered every filthy detail into the mic for anyone who wanted to hear real audio incest sex stories come to life.
