The house was quiet except for the low hum of the fridge when I got home from work. Mom was in the kitchen, her huge body bent over the counter as she scooped ice cream into a bowl. Her ass was enormous, wide and soft, stretching the thin fabric of her nightgown until it looked ready to split. At forty-two she was all heavy tits, thick thighs, and a belly that jiggled with every move. I’d been staring at that body for years.
“Late again, baby?” she asked without turning around. Her voice was thick and warm.
I stepped up behind her, pressing my already hard cock against the crack of her ass. “Couldn’t stop thinking about this fat ass all day.”
She pushed back, grinding slow. “Mmm, then take it. You know it’s yours.”
I yanked the nightgown up over her hips. No panties. Her pussy was already wet, lips plump and pink between those massive cheeks. I dropped my pants, grabbed her wide hips, and shoved my cock straight into her cunt in one thrust. She moaned loud, the sound bouncing off the cabinets.
“Fuck, yes,” she grunted. “Give Mommy that dick.”
I fucked her hard right there against the counter, her big body shaking with every slap of my hips. Her tits swung under her, heavy and full, nipples dragging against the cool granite. I reached around and grabbed one, squeezing the soft flesh while I pounded deeper. Her pussy gripped me tight, hot and sloppy, juices running down her thighs.
She came fast, legs trembling, a deep groan tearing out of her throat. “That’s it, fill me up, son. Flood Mommy’s fat pussy.”
I slammed in to the balls and unloaded, pumping thick ropes of cum into her while she milked every drop. When I pulled out, white cream leaked down her leg. She turned around, dropped to her knees, and sucked me clean, her tongue working my shaft like she was starving.
We moved to the couch after that. Mom stripped the nightgown off, letting her huge body spill free. Her belly hung soft over her mound, her tits sagging heavy and wide. I pushed her onto her back, spread those thick thighs, and buried my face in her cunt. She tasted like my cum and her own slick. I licked her clit in hard circles while two fingers pumped inside her.
“Eat that fat pussy, baby,” she panted, hands in my hair. “Suck Mommy’s big clit.”
She came again, thighs clamping around my head, juices flooding my mouth. Then she pulled me up, rolled onto her stomach, and lifted her ass high. “Fuck my ass now.

Stretch Mommy’s tight hole.”
I spit on her puckered rim and pushed my cock in slow. She was tight but took every inch, groaning into the cushions as I bottomed out. I fucked her ass deep and steady, watching her massive cheeks ripple with each thrust. My hands sank into the soft flesh, spreading her wider.
“Harder,” she begged. “Pound Mommy’s asshole like you own it.”
I did. I fucked her until she screamed into the pillow, her body shaking, another orgasm ripping through her. I pulled out and painted her huge ass with fresh cum, watching it drip between her cheeks.
Later we showered together. She soaped up my cock while I played with her tits, then bent over the tub so I could slide back into her pussy from behind. Water ran over her curves as I fucked her slow and deep, one hand reaching around to rub her clit until she came again, legs buckling.
By the time we fell into her bed, both of us were spent but still hungry. She climbed on top, straddling my hips, her massive body settling over me. Her pussy swallowed my cock again, and she rode me with slow, heavy rolls of her hips. Her belly and tits bounced and swayed. I grabbed handfuls of her ass, spreading her while she ground down.
“Love riding my son’s cock,” she moaned. “Love feeling you stretch this fat cunt.”
I came inside her one more time, holding her down as she milked me dry. She stayed on top afterward, my softening cock still inside her, both of us breathing hard.
She leaned down, kissed me deep, and whispered against my mouth, “Tomorrow night we’re doing it again. And you’re fucking my tits first.”
I smiled and squeezed her ass. “Wouldn’t miss it, Mom.”
We lay tangled together, her heavy body warm and soft against mine, both of us already thinking about the next round.
