John hadn't expected his visit to his grandmother's house to turn into anything more than a boring weekend of yard work and old stories. But the moment he stepped inside, his eyes locked on her heavy, buxom body. At sixty-eight, Margaret still carried massive tits that strained every button on her housedress, wide hips, and a thick ass that swayed when she walked. She hugged him tight, pressing those soft, warm breasts against his chest.
"Damn, you've grown up nice," she said, her voice low and direct. "Come sit with grandma."
They talked in the living room, but her eyes kept drifting to his crotch. She didn't waste time. "I saw how you looked at these," she said, cupping her huge tits through the thin fabric. "Want to see them for real? Your grandpa's been gone years. I need a good hard fuck."
John's cock twitched. "Grandma, we shouldn't—"
"Cut the bullshit," she snapped, standing up and pulling her dress over her head. Her bare breasts hung heavy and full, nipples thick and dark. Her pussy was shaved smooth, lips already glistening. "Get your cock out. Grandma wants to suck it."
He obeyed, dropping his pants. She dropped to her knees and took him straight into her mouth, no teasing. Her lips sealed tight around his shaft, sucking hard and wet while her hand pumped the base. Spit ran down her chin onto those big tits. "Mmm, young cock tastes good," she mumbled around him. "Fuck my face."
John grabbed her gray hair and thrust, driving deep into her throat. She gagged but didn't pull back, just took it, eyes watering as she swallowed around him. When he pulled out, strings of saliva connected her lips to his cock. "Now fuck grandma's pussy," she ordered, turning and bending over the couch, ass up.
He slammed into her from behind. Her cunt was hot, tight, and dripping. Margaret moaned loud and filthy. "That's it, fuck your grandmother hard. Pound that incest pussy." Her heavy tits swung beneath her with every thrust. John gripped her wide hips and drove in balls-deep, the wet slap of skin filling the room.
She reached back and spread her ass cheeks. "Stick a finger in grandma's asshole while you fuck me." He did, working one finger into her tight hole while his cock stretched her cunt. She pushed back, meeting every stroke. "Deeper, boy. Make grandma come on that dick."
Margaret came first, cunt clenching hard around him, juices running down his balls. "Don't stop," she growled. "Keep fucking me." He flipped her onto her back on the couch, lifted her thick legs over his shoulders, and drove back in. Her massive tits bounced with each thrust.

She grabbed them, squeezing and pinching her own nipples. "Suck grandma's tits while you fuck her."
He leaned down, sucking one fat nipple into his mouth, biting gently. She moaned louder. "Yes, just like that. Fuck your grandmother like a whore." Her pussy milked him, slick and greedy. He switched to the other tit, sucking hard while pounding her.
When he was close, she pushed him back and climbed on top, straddling him. Her heavy body settled down, taking every inch of his cock. She rode him slow at first, then faster, those big tits swinging in his face. "Come inside grandma," she demanded. "Fill my incest cunt with your load."
John grabbed her ass and thrust up hard, shooting deep inside her. She kept riding through it, milking every drop, then leaned down and kissed him rough, tongue sliding into his mouth. "Good boy," she panted. "Now get hard again. Grandma wants that cock in her ass next."
They moved to the bedroom. She got on all fours, reached back and spread her cheeks. John worked spit into her asshole, then pushed his cock in slow. Margaret groaned, pushing back until he was buried in her tight ass. "Fuck grandma's ass," she said, voice raw. "Make it hurt good."
He fucked her hard, one hand reaching around to rub her clit. She came again, ass squeezing him tight. "Keep going. Don't pull out until you fill it." He did, pumping another load deep in her ass while she moaned and shook.
Later, lying sweaty beside her, Margaret stroked his cock back to life with her hand. "We're not done," she said, rolling onto her side and lifting one leg. "Slide it back in grandma's pussy. Slow this time. Make it last."
He fucked her from behind, one hand full of her heavy tit, the other between her legs rubbing her swollen clit. They came together, her cunt pulsing around him as he emptied into her again.
Margaret turned and kissed him, softer now but still direct. "Next visit, bring a friend if you want. Grandma can handle two cocks." She smiled, already reaching for him again. "But for now, eat grandma's pussy clean."
John moved down between her thick thighs, licking his own cum from her used cunt while she held his head and told him exactly how she liked it. The night stretched long, filled with raw, filthy fucking until they both collapsed, bodies tangled and spent.
