The old family cabin creaked under the weight of our forbidden desires, the air thick with the scent of pine and sweat. I lay sprawled on the worn quilt of the king-sized bed, my legs hooked over Grandpa's broad shoulders as he positioned himself between them. His rough hands gripped my thighs, spreading me wide, his thick cock—veined and throbbing from years of pent-up hunger—pressing against my slick pussy entrance. At 18, I'd always known the spark in his eyes when he looked at me, but tonight, with the storm raging outside, we'd crossed the line.
Grandpa thrust forward, his cock stretching my tight pussy walls as he buried himself to the hilt in one powerful stroke. I gasped, my back arching off the bed, nails digging into his weathered arms. He groaned low, his hips snapping against mine, fucking me deep and relentless. Each plunge filled me completely, his balls slapping my ass with wet smacks, my juices coating his shaft as he claimed his granddaughter's hole. 'That's it, baby girl,' he grunted, leaning down to capture my nipple in his mouth, sucking hard while pounding harder, his pace building like the thunder outside.
Across the room, on the threadbare rug by the fireplace, Grandma had my brother pinned beneath her. At 20, he was all lean muscle, but she rode him like a woman possessed, her silver-streaked hair wild as she lowered her soaked pussy onto his rigid cock. She'd shed her nightgown earlier, her heavy breasts bouncing with every grind, nipples peaked and begging for attention. Brother's hands clutched her wide hips, guiding her as she fucked him upward, her ass cheeks clenching with each descent. She leaned back, one hand bracing on his thigh, the other rubbing her clit furiously while his dick speared into her depths.
'Fuck your grandma good, boy,' she moaned, her voice husky from decades of secrets. Brother bucked up to meet her, his cock disappearing into her greedy pussy over and over, the slick sounds mingling with Grandpa's grunts and my whimpers. Cum from her earlier teasing already leaked down his length, making their joining sloppy and intense. She rotated her hips, grinding her clit against his pubic bone, chasing the friction that made her walls flutter around him.
Grandpa didn't let up, his thrusts turning brutal, angling to hit that spot inside me that made stars burst behind my eyes. I wrapped my legs tighter around him, pulling him deeper, my pussy clenching as orgasm built low in my belly. He released my nipple with a pop, saliva trailing from his lips, and kissed me fiercely—tongue invading my mouth like his cock invaded my body. The taboo heat of it all, family tangled in raw lust, pushed me closer.
Brother cried out first, his body tensing as Grandma slammed down one last time, her pussy milking his cock until he erupted, hot spurts of cum flooding her insides. She shuddered, riding through her own climax, juices squirting around his base as she collapsed forward onto his chest, their breaths ragged. But Grandpa kept fucking me, his rhythm faltering as he watched them, the sight fueling his drive. 'Gonna fill you up, sweetheart,' he rasped, and with a final, deep shove, he did—his cock pulsing, unloading thick ropes of cum straight into my pussy, overflowing and dripping down my crack.
I came undone then, screaming his name as waves crashed over me, my body shaking in his arms. The room spun with our shared depravity, the storm outside nothing compared to the one we'd unleashed within these walls.
