The four of them had talked about it for weeks, but once the clothes came off in Mike and Sarah's living room, everything got raw fast. Lisa's husband, Tom, was already balls-deep in Sarah on the couch, grunting as he pounded her tight pussy. Across the room, Mike had Lisa bent over the arm of the chair, his thick fingers spreading her ass while he lined up that massive cock against her wet slit.
"Fuck, you're huge," Lisa moaned, pushing back. Mike didn't ease in. He slammed forward in one thrust, stretching her wide open with every inch of his fat dick. Lisa's eyes went wide, her mouth falling open in a silent scream as he bottomed out. Her husband glanced over but didn't stop fucking Sarah. The swap was on, and Mike's cock was ruining Lisa's pussy from the first stroke.
Mike grabbed her hips and drove in harder, his heavy balls slapping against her clit with every thrust. "Take it," he growled. "Your husband's cock isn't this big, is it?" Lisa shook her head, whimpering as her walls clenched around the thick shaft splitting her open. Juices ran down her thighs. Mike reached around and rubbed her swollen clit in rough circles while he fucked her deep, the head of his cock battering her cervix.
Tom pulled out of Sarah and watched, his own dick glistening. Sarah crawled over to him and started sucking, but his eyes stayed on his wife getting wrecked. Lisa was loud now, begging Mike not to stop. "Harder, please, your cock feels so fucking good." Mike flipped her onto her back, hooked her legs over his shoulders, and drilled straight down. The wet sounds of his huge cock pounding her soaked pussy filled the room. Lisa came hard, squirting around his shaft, her whole body shaking.
But the swap was already going sideways. Instead of switching back after the first round, Mike kept going. He pulled Lisa onto his lap and made her ride him, her tits bouncing as she impaled herself on every thick inch. Tom tried to pull Sarah into the bedroom, but she stayed to watch, fingering herself while Mike's massive cock disappeared into Lisa again and again.
When Mike finally pulled out, his cock was coated in Lisa's cream. He looked at Tom and said, "You want a turn with your wife or you want to see what a real cock does?" Tom didn't answer with words. He pushed Lisa onto her knees and fed his dick into her mouth while Mike lined up behind her again. They took turns, Mike's huge cock stretching her pussy while Tom fucked her throat. Lisa gagged and moaned around both of them, spit and pussy juice everywhere.
The night turned into hours of raw fucking. Mike claimed Lisa's ass next, working that massive cock into her tight hole while she screamed into the cushions. Tom watched his wife get stretched and used, then slid under her to eat her pussy while Mike kept pounding.
Lisa came again, shaking between the two men. By the time Mike flooded her ass with thick ropes of cum, the original plan was dead. No one was swapping back nicely.
They ended up in the same bed, bodies tangled. Lisa rode Mike's huge cock one more time while Tom fucked her mouth, both men using her until she was a dripping, satisfied mess. When they finally collapsed, Lisa lay between them, cum leaking from both holes, her voice hoarse from moaning. "We should do this again," she whispered. Mike's hand rested on her thigh, his softening cock still impressive against his leg. Tom didn't argue. The wife swap had gone wrong, but the night had turned into something dirtier and hotter than any of them planned.
