I showed up at my grandmother's place on a hot Saturday afternoon, my dick already twitching in my jeans from the dirty thoughts I'd been having all week. She opened the door in a thin housedress that clung to her heavy tits and wide hips, her gray hair pulled back but a few strands loose around her wrinkled but still pretty face. "Get in here, boy," she said, voice low and knowing. I stepped inside and she locked the door behind me.
She didn't waste time. Her hands went straight to my belt, yanking it open. "You've been thinking about this old pussy, haven't you?" she growled, dropping to her knees right there in the hallway. Her mouth was hot and wet as she pulled my cock out and swallowed it down in one greedy gulp. I groaned, grabbing her hair as she sucked me hard, spit running down her chin while her tongue worked the underside. She pulled off just long enough to say, "Fuck your grandmother's mouth like you mean it," then took me deep again, gagging but not stopping.
I thrust into her throat, watching her eyes water, her big tits heaving. She reached under her dress and started fingering herself, moaning around my shaft. When she pulled back, strings of spit connected her lips to my cock. "Bedroom. Now."
We barely made it to her bed before she hiked up her dress and bent over the edge, ass up. No panties. Her cunt was shaved smooth, lips puffy and glistening. "Eat it," she ordered. I dropped behind her and buried my face in that wet slit, tongue lapping from her clit to her asshole. She tasted musky and sweet, and she pushed back against my mouth, grinding while I sucked her swollen nub. "That's it, you dirty grandson. Lick grandma's cunt."
She came hard on my tongue, juices coating my chin. Then she flipped around, spread her legs wide, and pulled me on top of her. "Stick that young cock in me. Fuck me raw." I slammed into her in one thrust. She was tight for her age, hot and slick, gripping me like a vice. I pounded her hard, the bed creaking, her heavy tits bouncing with every stroke. She clawed my back and snarled, "Harder. Fuck your grandmother like a whore."
We switched positions fast. She climbed on top, sank down on my cock, and rode me with filthy enthusiasm, her ass slapping against my thighs. "Look at you, buried in grandma's pussy," she panted, reaching back to rub her clit while she bounced. I grabbed her hips and thrust up to meet her, watching her face twist in pleasure.

She came again, cunt pulsing around me, soaking my balls.
I flipped her onto her back, hooked her legs over my shoulders, and drove in deep. Her tits shook, nipples hard. "Fill me up," she demanded. "Shoot that load in your grandmother's cunt." I fucked her faster, the wet sounds loud and obscene, until I exploded inside her, pumping thick ropes of cum deep while she milked every drop with her squeezing walls.
We didn't stop there. She sucked me hard again, tasting our mixed juices, then had me take her from behind on all fours, pounding her ass while she fingered her cum-filled pussy. Later she rode my face, smothering me with her wet cunt until she squirted. By the time we finished hours later, both of us were slick with sweat and cum, her body marked with my handprints.
She kissed me slow and dirty afterward, tongue sliding against mine. "Same time next week, boy. Grandma's pussy needs regular attention." I left with her scent all over me, already planning the next visit.
