I never planned on banging my fat grandma, but the second she bent over in that tight housedress, her huge ass cheeks spreading wide and her heavy tits hanging low, my cock got rock hard and I knew I was gonna stuff her pussy full of family dick.
It started on a rainy afternoon at her place. Grandma Ruth was 68, thick as hell with a soft belly that jiggled, massive thighs, and tits so big they strained every button on her blouse. She had always been the sweet, baking type, but lately her eyes lingered on me too long when I came over to fix things. That day I was helping move boxes in the attic. Sweat made her dress cling to her curves, outlining the fat rolls on her sides and the deep cleft of her ass.
"Damn, boy, you're getting strong," she said, her voice low and husky. She wiped her forehead, and her dress pulled tight across those enormous breasts. No bra. Her nipples poked out like thick pebbles.
I couldn't stop staring. My mind flashed to every dirty thought I'd ever had about older women, and here she was, my own blood, looking like she wanted it.
"You like what you see?" she asked suddenly, turning to face me. Her hand went to her hip, pushing her belly out. "I know you've been peeking. Your grandpa's been gone years. A woman like me gets needs."
My mouth went dry. "Grandma… we can't."
"Can't what? Fuck?" She stepped closer, her heavy body pressing against mine. Her soft gut rubbed my crotch and she felt my hard-on immediately. A slow smile spread across her face. "Oh, you can. And you will."
She grabbed my belt, yanked it open, and pulled my cock out. Her fat fingers wrapped around it, stroking slow and firm. "Thick like your daddy's. Been wanting this in my cunt for months."
She dropped to her knees with a grunt, her knees spreading wide on the attic floor. Her mouth opened and she sucked me down, sloppy and wet. Spit ran down her chin onto her big tits. She gagged herself on it, eyes watering, but kept bobbing, tongue swirling under the head.
"Fuck, Grandma," I groaned, grabbing her gray hair. She moaned around my shaft, the vibration making my balls tighten.
After a minute she pulled off, strings of spit connecting her lips to my dick. "Get on the bed downstairs. Now."
We barely made it to her bedroom. She stripped fast, letting those huge tits flop free, dark areolas wide and nipples stiff. Her belly hung over her shaved pussy, fat lips already glistening. She climbed onto the bed on all fours, ass up, cheeks spreading to show her puckered asshole and dripping slit.
"Put it in, boy. Fuck your fat grandma's cunt."
I climbed behind her and slammed home in one thrust. She was tight inside, hot and wet, her walls gripping me. Her ass cheeks rippled with every slap of my hips. The bed creaked loud as I pounded her, watching her fat body shake. She reached back and spread her cheeks wider.
"Harder. Use that family cock. Fill me up."
I reached under and grabbed her swinging tits, squeezing the soft flesh, pinching her nipples. She pushed back, meeting every thrust, her belly slapping against the mattress. Sweat poured off us. The room smelled like sex and her cheap perfume.
She flipped over onto her back, legs spread wide, knees to her chest. Her pussy was red and swollen, clit poking out. I drove back in, watching my cock disappear into her fat folds. She rubbed her clit fast while I fucked her.
"Talk dirty to me," she panted. "Tell me how you love fucking your grandma."
"Your pussy's so fucking good, Grandma.
So wet and tight. I'm gonna cum deep in your cunt."
"Do it. Breed me like the slut I am."
I felt her start to cum first. Her walls fluttered and clamped down, a gush of juice soaking my balls. She screamed, body shaking, tits bouncing wildly. That pushed me over. I buried myself to the hilt and unloaded, pumping rope after rope of thick cum into her. It leaked out around my cock, running down her ass crack.
We stayed locked together, breathing hard. She pulled me down for a deep kiss, tongue pushing into my mouth.
"Next time," she whispered against my lips, "you're fucking my ass too. And maybe we'll bring your cousin over. Keep it all in the family."
I was already getting hard again inside her.
We spent the rest of the afternoon switching positions. She rode me, her fat body bouncing, belly and tits slapping. I took her from the side, one leg hooked over my shoulder so I could watch my cock stretch her pussy. She sucked me clean between rounds, licking our mixed cum off my shaft with greedy moans.
By evening we were both sore and sticky, but she made me promise to come back every week. "Your grandpa never fucked me like that," she said, patting her cum-filled pussy. "Now get out before your mom calls. And don't tell anyone… unless you want to share me."
I left with her scent on my clothes and the taste of her on my tongue, already planning the next visit. Family secrets like this were too good to quit.
