She walked into the living room wearing nothing but a thin robe that barely covered her heavy tits. "You been watching that shit again?" she asked, voice low and rough. Her son sat on the couch, cock already half-hard in his shorts from the video on his laptop. Two people fucking on screen, the woman moaning like a whore while the guy pounded her from behind.
"Yeah," he said, not hiding it. "You want to see?"
She didn't answer with words. She dropped the robe and climbed onto the couch beside him, her bare thigh pressing against his. Her hand went straight to his lap, squeezing his dick through the fabric. "Show me what you like, baby."
He clicked play. The video got louder, wet sounds filling the room. She pulled his shorts down and wrapped her fingers around his thick cock, stroking slow at first, then faster. "Look at that pussy taking it," she muttered. "You want your mom to take it like that?"
He groaned and pushed two fingers between her legs. She was already soaked. He slid them inside her cunt, pumping hard while she jerked him off. The porn kept playing, bodies slapping together. She leaned over and took his cock in her mouth, sucking deep, tongue swirling around the head.
"Fuck, Mom," he said, hips lifting. She bobbed faster, gagging a little but not stopping. Spit ran down his shaft onto his balls. He grabbed her hair and fucked her throat until she pulled off, gasping.
She straddled him right there on the couch. "Put it in," she ordered. He lined his cock up and she sank down, taking every inch into her tight, wet pussy. She rode him hard, tits bouncing in his face. He sucked on her nipples while she ground down, clit rubbing against him.
The porn video switched to a new scene, another mom-son style clip playing by coincidence. She laughed dirty. "They got nothing on us." She turned around, reverse cowgirl, and slammed down again, ass cheeks spreading as she took him balls deep.
He reached around and rubbed her clit while she bounced. Her juices coated his cock and dripped onto the cushions. "Harder," she demanded. He thrust up to meet her, pounding her cunt until she came, walls clenching around him, screaming his name.
She didn't stop. She got on all fours on the floor and looked back at him. "Fuck your mom's ass." He spit on her hole and pushed in slow, then faster once she relaxed.

He gripped her hips and railed her, watching his cock disappear into her tight ass while the porn kept moaning in the background.
They switched positions again, her on her back on the rug, legs over his shoulders. He fucked her pussy raw, deep and steady, sweat dripping off both of them. She came twice more, squirting a little on the third one. When he was close she pulled him out and jerked him onto her tits and stomach, thick ropes of cum painting her skin.
They lay there catching their breath, the video still running. She scooped some cum off her chest and licked it off her fingers. "Next time we make our own," she said.
He was already getting hard again.
