I found the best site for incest sex stories on a rainy Tuesday night when I was already half-drunk and horny as hell. The tab opened to a forum full of raw, no-holds-barred tales, and one in particular grabbed my cock by the throat: a brother and sister who started with stolen panties and ended up fucking like animals in their parents' bed. I stroked myself raw reading it, but the real heat hit when my own sister, Mia, walked in without knocking.
She was twenty-two, same as me, fresh out of college and crashing in the guest room while she looked for work. Tight tank top, no bra, nipples poking through the thin cotton. She caught me with my hand wrapped around my dick and the screen glowing with filthy words about siblings.
"Jesus, Jake," she said, but she didn't leave. Her eyes dropped to my hand, then back to the screen. "Is that what you're into?"
I didn't answer with words.
I turned the laptop so she could see the story. The brother in it was balls-deep in his sister, describing how tight and wet she was. Mia licked her lips. "You think that's hot?"
"Read it," I told her, voice rough. "Out loud."
She hesitated for half a second, then started reading in that low, dirty voice she saved for late-night talks. Every sentence made my cock twitch harder. When she got to the part where the sister begged for her brother's cum, Mia's hand slipped between her own legs. She was standing right there, rubbing herself through her shorts while she read.
"Fuck this," I muttered. I grabbed her wrist and pulled her onto the bed. She landed on top of me, and our mouths crashed together like we'd both been waiting years. Tongues, teeth, her tasting like mint and bad decisions. I yanked her tank top up and sucked her tits, biting just enough to make her gasp. She ground down on my cock through my jeans, soaking the denim with how wet she already was.
"Take them off," she ordered, yanking at my zipper. My cock sprang free, thick and leaking. She wrapped her fist around it and stroked once, twice, then leaned down and swallowed me. Hot, wet mouth sliding all the way to the base. I fucked her throat while she gagged and moaned around me, spit running down my balls.
I flipped her onto her back, ripped her shorts off, and buried my face between her thighs. She tasted sweet and forbidden, clit swollen under my tongue. I licked and sucked until she was shaking, then drove two fingers into her tight cunt, curling them against that spot that made her scream my name.
"Fuck me," she begged. "Right now. Like in the story."
I didn't make her ask twice. I shoved her legs wide and slammed into her in one thrust. She was soaked, gripping me like a fist. We fucked hard and nasty, skin slapping, her tits bouncing with every drive of my hips. I called her my dirty little sister while she clawed my back and told me to fill her up.
We changed positions like the stories on that site: her on all fours, me pounding her from behind while I reached around to rub her clit; then her riding me reverse, ass bouncing as she took every inch; finally her on her back again with my hand around her throat, both of us coming so hard the headboard cracked the wall.
After, we lay there panting, her cum and mine leaking out of her onto the sheets. She reached over, clicked the laptop, and bookmarked the site.
"Best site for incest sex stories," she whispered, already stroking me hard again. "We should write our own."
We spent the rest of the night making sure every filthy detail was true.
