The house was quiet except for the creak of the old couch under their combined weight. Linda, all 280 pounds of her, sat there in nothing but an oversized t-shirt that barely covered the bottom of her massive ass. Her belly spilled over her thick thighs, soft and pale, jiggling every time she shifted. Her son Mark, 22 and built just like her at 260 pounds, stood in the doorway watching. His cock was already hard, straining against his shorts.
"Get over here, baby," Linda said, her voice low and rough. "Mommy's been thinking about this all day."
Mark didn't hesitate. He crossed the room, dropped his shorts, and let his thick dick spring free. It was heavy, veined, and already leaking. Linda reached out and grabbed it with one fat hand, squeezing hard.
"Fuck, your cock feels good," she muttered. She pulled him closer until he stood between her spread legs. Her belly pressed against his thighs as she leaned in and licked the head, tasting the precum. "Tastes like you want Mommy bad."
Mark groaned and pushed forward. Linda opened her mouth wide and took him in, her fat cheeks hollowing as she sucked. Saliva ran down her chin onto her huge tits. She bobbed her head, making wet, sloppy sounds while one hand reached down to rub her own fat pussy, already slick.
"Stand up," Mark said after a minute. "Turn around."
Linda heaved herself up, her body wobbling. She bent over the arm of the couch, presenting her enormous ass. The cheeks were wide and dimpled, the crack deep. Mark spread them and spat on her asshole, then lined his cock up with her dripping cunt instead. He shoved in hard.
Linda gasped, her whole body shaking. "That's it, fuck your fat mother. Pound that pussy."
Mark gripped her wide hips, fingers sinking into the soft flesh, and started thrusting. Each slam made her ass ripple and her belly slap against the couch. The wet sounds of his cock driving into her were loud and filthy. He reached around and grabbed one of her heavy tits, pinching the nipple.
"Harder, you little bastard," Linda growled. "Make Mommy cum on that dick."
He fucked her faster, his heavy balls slapping against her. Sweat ran down both their bodies. Linda's pussy clenched around him, soaking his shaft. She reached back and spread her ass cheeks wider so he could see everything.
Mark pulled out, flipped her onto her back on the couch, and climbed on top. Her belly and his pressed together, soft fat meeting fat. He pushed back inside her and kept going, grinding deep. Linda wrapped her thick legs around him as best she could.
"Fill me up," she panted. "Cum in Mommy's fat cunt."
Mark slammed in one last time and unloaded, pulsing thick ropes inside her. Linda came right after, her whole body quaking, juices squirting around his cock. They stayed locked together, breathing hard, sweat and cum mixing between their heavy bellies.
Later they moved to the bedroom. Linda got on all fours again, this time demanding he take her ass. Mark worked his cock into her tight hole, stretching her while she fingered her pussy and talked dirty the whole time. They fucked until both were spent, bodies slapping, the room smelling like sex and sweat.
By morning they were still tangled, Mark's cock half-hard against his mother's fat thigh, already planning the next round.
