Jake slammed the laptop shut after scrolling through another batch of free sex stories time incest threads, his cock already throbbing in his jeans. He knew it was twisted, but the idea of fucking his own sister had burned in him for years. Tonight, with their parents gone for the weekend, he was done pretending.
He found Lisa in the kitchen, wearing nothing but an old tank top and tiny shorts that barely covered her ass. She was 24, same as him, and she looked up with that knowing smirk she'd been giving him since they both turned eighteen and started stealing glances.
"You've been staring at me all day," she said, voice low and rough. "Thinking about those stories again?"
Jake didn't bother with words. He grabbed her by the hips, spun her around, and bent her over the counter. "Shut up and spread your legs." He yanked her shorts down, exposing her smooth, wet pussy. Two fingers slid right in, and she was dripping already.
"Fuck, Jake," she moaned, pushing back against his hand. "Do it. I've wanted your cock for so long."
He freed his thick dick, lined it up, and slammed inside her in one hard thrust. Lisa cried out, gripping the edge of the counter as he started pounding her. No slow build, just raw, filthy fucking. His balls slapped against her with every stroke, and the wet sounds of her cunt taking him filled the room.
"Yeah, take your brother's cock," he growled, reaching around to rub her clit. "This is what you get for teasing me all these years."
Lisa pushed back harder, meeting every thrust. "Harder. Fuck me like you mean it.
Fill me up."
Jake obliged, gripping her hair and yanking her head back while he drilled into her. Her tits bounced under the tank top, nipples hard. He pulled out just long enough to spin her around, lift her onto the counter, and shove back in. Her legs wrapped around him, heels digging into his ass as he fucked her deep and fast.
She came first, clamping down on his cock, juices running down his shaft. "Don't stop," she gasped. "Keep going."
He didn't. He fucked her through it, then pulled her off the counter and bent her over the kitchen table instead. From behind again, he spread her cheeks and watched his cock disappear into her soaked hole. "Look at this greedy pussy. Made for incest."
"Give it to me," she begged. "Cum inside me."
Jake's pace turned brutal, hips snapping forward until his balls tightened and he unloaded deep in her, pumping thick ropes of cum into his sister's cunt. He stayed buried, grinding against her as the last spurts filled her.
They weren't done. He dragged her to the couch, pushed her down on all fours, and ate her out from behind, tongue lapping up their mixed mess before sliding his still-hard cock back in. Lisa reached back to spread herself wider, moaning dirty encouragements the whole time.
By the time they collapsed, sweaty and spent, the night had turned into exactly what those free sex stories time incest fantasies promised: repeated, no-limits fucking between siblings who'd waited too long. Lisa curled against him, cum leaking from her, and whispered, "Next round in my bed. Don't pull out this time."
