I came home from college that summer and everything changed the second I saw her bent over the kitchen counter. Mom's huge ass was straining against those thin yoga pants, the fabric stretched so tight it looked painted on. Her cheeks were massive, round and heavy, jiggling with every little move she made while she loaded the dishwasher. I stood there frozen, my cock already thickening in my shorts as I stared at that big bottom I had jerked off to for years.
She turned and caught me looking. Instead of getting mad, she smiled slow and dirty. "Like what you see, baby? Your mom's big ass got you all worked up?" Her voice was low and teasing. She walked over, hips swaying, and pressed that thick body right against me. Her tits mashed into my chest while she reached down and grabbed my hard dick through my pants.
"Fuck, you're big," she whispered. "Bigger than your dad. Been wanting this big bottom for a long time, haven't you?" She spun around, grinding her ass back against my crotch. The heat from her pussy was obvious even through the layers. I grabbed two handfuls of those fat cheeks and squeezed hard, feeling the soft flesh overflow my hands.
Mom moaned and bent forward over the table, pushing that enormous ass higher. "Pull my pants down and fuck me right here. I know you've been dreaming about slamming your cock into your mother's big bottom." I yanked the yoga pants down in one rough tug. Her bare ass exploded into view, pale and jiggly with deep dimples and a thick, juicy cleft. No panties. Her pussy lips were already slick and puffy.
I dropped my shorts and shoved my cock straight into her wet cunt in one hard thrust. She was tight but soaked, gripping me as I started pounding. Her big bottom rippled and clapped with every slam of my hips. The sound was filthy, skin on skin, wet squelching as I fucked her deep. Mom pushed back, meeting every stroke, her ass cheeks spreading around my shaft.
"Harder, son. Wreck this big mom ass," she growled, reaching back to spread herself wider. I slapped one cheek and watched it shake, then grabbed her hips and drove in balls-deep. Her asshole winked at me above my plunging cock. I spit on it and rubbed my thumb around the tight ring while I kept fucking her pussy raw.
She came first, screaming my name, her big bottom clenching and spasming around me. Juices ran down her thighs. I didn't stop. I pulled out, lined up with her asshole, and pushed in slow but steady. Mom hissed and pushed back, taking every inch until my cock was buried in her hot, gripping ass.
I fucked that hole just as rough, watching her massive cheeks bounce and spread.
We moved to the couch after that. She rode me reverse, that big bottom smothering my lap as she bounced and ground. Her cheeks swallowed my cock completely on every drop. I reached around and rubbed her clit while she worked her ass up and down. She came again, squirting over my balls, and I filled her asshole with thick ropes of cum.
Later that night she let me fuck her big bottom again in her bed, this time with her on all fours, ass up high. I spread her cheeks wide and watched my cock disappear between them over and over. She talked filthy the whole time, telling me how much she loved her son's cock in her mom pussy and ass. We kept going until the sun came up, my cum leaking from both holes, her big bottom red from all the slapping and pounding.
It became our regular thing that summer. Every chance we got, I was buried in that huge, perfect ass, raw and direct, exactly the way she wanted it. Mom's big bottom owned me, and I owned it right back.
