Sarah had been married to Tom for fifteen years when the cheating started with her own son. At forty-two she still had a tight body, heavy tits that sagged just enough to look real, and a shaved pussy that got wet the second she thought about cock. Tom was gone on another business trip, leaving her alone in the house with their eighteen-year-old son, Jake. The boy had come home from college for the weekend and Sarah could not stop staring at the bulge in his jeans.
She cornered him in the kitchen after dinner. "Jake, your dad is not here. I need a real man tonight." She dropped to her knees right there on the tile floor, unzipped him, and pulled out his thick cock. It was longer than Tom's and already hard. Sarah opened her mouth and took him deep, gagging on the head as spit ran down her chin. Jake groaned and grabbed her hair, fucking her face in hard thrusts.
"Fuck, Mom, suck that cock," he growled.

She moaned around his shaft, her pussy dripping into her panties. When he was slick and throbbing she stood up, bent over the counter, and hiked her skirt. "Fuck your cheating mom. Put it in my cunt." Jake shoved her thong aside and slammed into her wet hole in one stroke. Sarah cried out, pushing back to take every inch. He pounded her hard, the wet slap of skin filling the kitchen, her big tits swinging free after she yanked her top down.
They moved to the living room couch. Sarah stripped naked and climbed on top, guiding his cock back into her dripping pussy. She rode him fast and dirty, grinding her clit against him while she talked filthy. "Your father's cock never feels this good. Fill your mom's cheating cunt. Fuck me like the slut I am." Jake thrust up to meet her, hands squeezing her ass, spreading her cheeks so he could watch his cock disappear inside her. She came hard, pussy clenching and squirting a little around his shaft.
Later that night she took him to the master bedroom, the one she shared with Tom. She got on all fours on the marital bed and begged Jake to fuck her ass. He spit on her hole and worked his cock in slow at first, then harder once she relaxed. Sarah reached back to rub her clit while he stretched her tight ring. "Deeper, baby. Wreck Mommy's asshole. Your dad never gets this." Jake fucked her ass raw until he pulled out and sprayed thick ropes of cum across her back and ass cheeks.
They kept going all weekend. Sarah let Jake fuck her in the shower, bent over the bathroom sink, and once on the dining room table with her legs spread wide. Every time she came she moaned about how much better her son's cock was than her husband's. By Sunday night she was sore, covered in dried cum, and already planning the next time Tom would be out of town so Jake could come home and use her again.
When Tom called to say he was delayed another day, Sarah smiled and told Jake to stay longer. She dropped to her knees again as soon as she hung up, sucking her son's cock while she looked up at him. "Mommy's your cheating whore now. Use me however you want." Jake grabbed her head and fucked her throat until he flooded her mouth. She swallowed every drop and licked him clean, already wet for the next round.
