I never planned on fucking my grandma, but once I saw that huge ass jiggle in those tight shorts, there was no turning back. It started on a hot summer afternoon when I came over to fix her leaky faucet. She was seventy-two, thick as hell, with wide hips and an ass that looked like it belonged on a much younger woman. The way it swayed when she walked to the kitchen for lemonade made my cock twitch in my jeans.
"Damn, Grandma, you been working out?" I joked, trying to keep it light while my eyes stayed glued to her backside.
She laughed, that low, throaty sound, and bent over the sink to show me the drip. Her shorts rode up, splitting those fat cheeks like they were begging to be spread. "Boy, these old bones still got some bounce left. Your grandpa used to say the same thing before he passed."
I stepped closer to help with the wrench, but my hand brushed against that ass by accident. Or maybe not. It was soft, heavy, and warm through the thin fabric. She didn't pull away. Instead, she pushed back just a little, grinding against my palm.
"Grandma…" I started, voice rough.
"Shh, baby. We've both been lonely. Your mama don't need to know." She turned around, eyes dark with something hungry. Her hand went straight to my crotch, squeezing the hard length there. "Been a long time since I felt a young cock like this."
I didn't waste time. I spun her back to the counter, yanked those shorts down, and watched that massive ass spill out. Pale, dimpled, but round and jiggly, with deep cleft between the cheeks. My fingers sank into the flesh as I spread her open. She was already wet, her pussy lips puffy and glistening under a neat patch of gray hair.
I dropped to my knees and buried my face between those cheeks, tongue lapping at her asshole first, then sliding down to her cunt. She tasted musky and sweet, and she moaned loud, pushing back so my nose pressed into her crack. "Eat Grandma's big ass, boy. Lick it good."
I did, slurping and sucking until her thighs shook. Then I stood, freed my throbbing dick, and slammed it straight into her soaked hole. She was tight despite her age, gripping me like a fist. I fucked her hard from behind, watching that ass ripple with every thrust, the cheeks clapping against my hips.
"Harder, fuck your grandma harder," she grunted, reaching back to spread herself wider.
I grabbed handfuls of that fat ass, using it as handles while I pounded deep. The wet sounds filled the kitchen, skin slapping skin.
We moved to the living room couch. She climbed on top, that huge ass facing me as she lowered onto my cock in reverse. I watched it swallow every inch, the cheeks swallowing my view until only my balls showed. She rode me slow at first, grinding and bouncing, making those globes shake and wobble. I spanked them red, leaving handprints on the pale skin.
"Grandma's big ass is all yours now," she panted, leaning forward so I could see everything. I thrust up to meet her, driving into her cunt while my thumb circled her asshole. She came first, clamping down and soaking my shaft with her juices, her whole body quaking.
I flipped her onto her back, legs pushed to her chest, and buried myself again. Her tits sagged heavy but her ass still lifted off the cushions, inviting more. I came deep inside her, pumping thick ropes while she milked me dry with those inner walls.
Afterward, we lay tangled, my cum leaking from her well-fucked pussy onto the couch. She smiled, stroking my softening cock. "Next time, I want you in my ass, baby. That big thing will stretch Grandma real good."
We kept it going all summer, every visit turning into raw, secret fucking. No one ever found out, and that just made her big ass even more addictive.
