I was home from college for the summer when it started with my sister Lisa. She was twenty-one, same as me, and we had the house to ourselves while our parents were on their cruise. Lisa had always been the hairy type, dark curls under her arms when she raised them, thick black hair on her legs she never shaved, and I knew from laundry duty that her pussy was covered in the same wild bush. One hot afternoon she walked out of the shower with just a towel, and it slipped. Her tits were full, nipples dark, but my eyes locked on that thick, untamed triangle between her legs, hair spilling out thick and curly, hiding her slit but not the scent of her soap and natural musk.
"Fuck, Lisa, you're hairy as hell down there," I said, voice low and direct.
She didn't cover up. Instead she smirked and dropped the towel. "Yeah? You like that hairy pussy, big brother? Bet yours is just as thick."
My cock was already hard in my shorts. I pulled them down right there in the hallway. My dick sprang out, heavy and veined, with a dense bush of my own black hair around the base and balls hanging low and furry. Lisa stepped closer, reached out, and wrapped her hand around my shaft, fingers sinking into the hair.
"Goddamn, it's thick," she muttered, stroking slow and firm. "Mom always said our family runs hairy. Never thought I'd be jerking my brother's hairy cock."
I grabbed her ass, pulled her in, and rubbed my dick against her hairy mound. The coarse hair on her pussy lips dragged against my shaft, scratching in the best way. She moaned and spread her legs, letting me grind the head of my cock through those thick curls until it found her wet slit. She was dripping already, juices soaking the hair.
We didn't make it to the bedroom. I pushed her against the wall, lifted one of her hairy legs, and shoved my cock straight into her. She was tight, hot, and that bush cushioned every thrust, her pubic hair mashing against mine with wet, sticky sounds. "Fuck me harder, bro," she growled. "Pound that hairy sister pussy."
I did. My balls slapped her ass, the hair on them rubbing her skin raw.
She clawed my back, her underarm hair brushing my face when she held on. I came deep, pumping thick ropes into her while her hairy cunt clenched and milked me, her own orgasm making her bush glisten with our mixed cum.
After that we didn't stop. That night she came to my room naked, bush already matted from fingering herself. She sat on my face first, grinding that hairy pussy all over my mouth. I licked through the curls, sucked her clit while her thick hair tickled my nose and tongue. She tasted salty and sweet, juices running down my chin. Then she spun around and took my cock in her mouth, gagging on it while her hairy tits swung and brushed my thighs.
We fucked three more times that night. Doggy style so I could watch her hairy asshole wink and her bush sway. Me on top, pinning her legs back so every thrust parted those thick lips and exposed pink inside the black hair. She rode me reverse, reaching down to spread her bush and show me my cock disappearing into her.
By morning we were both covered in dried cum and sweat, our body hair stuck together wherever we touched. Lisa looked at me with that same dirty grin. "This is our secret, right? Hairy incest sex stories just for us."
I nodded, already hard again, and pulled her back onto my cock. We kept going all summer, every position, every room, her hairy body and mine rubbing raw and filthy until we both knew we'd never want anyone else.
