I slammed the laptop shut but it was too late. The images were burned behind my eyesmy stepbrother's thick cock buried in our stepmom's dripping cunt while she moaned like a whore. The story had been right there on that free site, tagged exactly like the rest: "free online family sex stories." I told myself I was just browsing, but my panties were soaked and my fingers were already sliding under the waistband.
Jake walked in without knocking, like always. "What the fuck are you looking at, sis?" His voice was low, rough. He saw the flush on my cheeks and the way my hand jerked out of my shorts. He grinned that dirty grin and stepped closer. "You reading that shit again?"
I didn't answer. I just stood up, grabbed his belt, and yanked him toward me. "Shut up and fuck me like they do in those stories."
He didn't need more than that. His mouth crashed down on mine, tongue pushing deep while his hands ripped my tank top off. My tits spilled out and he grabbed them hard, thumbs flicking my nipples until I gasped. "You want it nasty, don't you?" he growled. "Want your big brother stretching that tight little pussy."
I dropped to my knees right there on the bedroom floor. His cock was already hard, straining against his jeans. I freed it, thick and veined, the head already leaking. I licked the slit first, tasting salt, then took him deep, gagging when he hit the back of my throat. He fucked my face like he owned it, hands tangled in my hair, hips snapping forward. Spit ran down my chin onto my tits. "That's it, swallow every inch," he grunted. "Just like those filthy stories you love."
He pulled out and hauled me up, spinning me around. Bent me over the desk. Yanked my shorts and panties down in one rough tug. Two fingers shoved straight into my cunt, pumping hard. "So fucking wet. You been reading that crap and getting off thinking about family cock, huh?"
"Yes," I hissed. "Now put it in me."
He didn't tease. He lined up and drove straight home, burying every thick inch in one thrust. I cried out, walls clenching around him. He fucked me like an animalhard, fast, balls slapping my clit with every stroke. The desk shook. My tits swung under me. He reached around and rubbed my swollen clit in tight circles while he pounded deeper.
"Harder," I begged. "Make it dirty like the stories."
He pulled out, flipped me onto my back on the bed, and shoved back in. My legs went over his shoulders. He leaned down and spat on my clit, then rubbed it while he fucked me open. "You like that? Like getting used by your stepbrother? Bet you'd let Dad watch too if he walked in."
The filthy talk pushed me over. I came hard, pussy pulsing, juices squirting around his cock. He kept slamming through it until he pulled out at the last second and painted my stomach and tits with thick ropes of cum. I rubbed it into my skin while he watched, breathing heavy.
We didn't stop there. He flipped me again, spread my ass, and licked my hole until I was begging. Then he worked two fingers into my ass while he slid back into my cunt. Double penetration with just his hands and cock had me shaking. When he finally pushed his dick into my ass, slow at first then deep, I came again, screaming into the pillow.
Later, sweaty and wrecked, he pulled me against him. "Next time we find one of those free online family sex stories together," he said, voice still rough.
"And we act out every single filthy page."
I smiled against his chest, already planning which one we'd try next.
