Mark and Lisa had been eyeing Tom and Jenna for months at those backyard barbecues. The tension finally snapped one Friday night when Tom flat out said it over beers. "Let's swap. You take Jenna, I take Lisa. No holding back, just raw fucking like we all want." Lisa's face flushed but she nodded fast, already rubbing her thighs together. Jenna grinned and grabbed Mark's hand, pulling him toward the bedroom while Tom shoved Lisa against the wall in the living room.
Tom didn't waste time. He yanked Lisa's dress up, ripped her panties aside, and shoved two fingers straight into her wet cunt. "Fuck, you're soaked already. Been thinking about my cock all night, haven't you?" Lisa moaned and spread her legs wider. "Yes. Give it to me. Pound my married pussy while my husband rails your wife." Tom dropped his pants, slapped his thick cock against her clit a few times, then slammed in balls deep in one thrust. Lisa cried out and clawed his back, her tits bouncing with every hard stroke.
In the bedroom, Jenna was on her knees sucking Mark like she was starving. She took him to the back of her throat, gagging wetly, spit running down his shaft. "Your wife's gonna feel this same cock stretching her soon," Mark growled, gripping her hair. Jenna pulled off just long enough to say, "Fuck her throat too. Make her choke on it." Then she climbed on the bed, spread her legs, and told him to mount her. Mark drove in hard, pounding her tight cunt with long, punishing strokes while she screamed for more.
Tom flipped Lisa onto all fours on the couch and fucked her from behind, his hips slapping loud against her ass. "Look at this greedy hole swallowing my dick. Your husband watching would love this view." Lisa pushed back, meeting every thrust. "Harder. Use me. Fill me up so I drip your cum when I walk back to him." Tom reached under and rubbed her clit in rough circles until she came, cunt pulsing and squeezing his cock.
Jenna rode Mark reverse cowgirl, bouncing hard, her ass cheeks rippling. He smacked it red and reached around to finger her asshole while he fucked her. "Tell me how my wife's cunt feels around your husband's cock," she demanded. Mark grunted, "Tight and hot, just like yours. They're probably both creaming right now." Jenna came with a loud shout, her juices soaking his balls.
The couples switched after the first round. Lisa crawled into the bedroom on shaky legs and immediately straddled Mark's face while Tom took Jenna on the same bed. Lisa ground her cum-slick pussy on Mark's tongue while Tom fucked Jenna missionary, legs pinned back, pounding deep. "Swap my load into her," Tom ordered. Mark flipped Lisa onto her back and drove into her, mixing Tom's cum with fresh thrusts. The room filled with wet sounds, moans, and filthy talk.
They kept going, switching positions and partners again. Mark took Jenna from behind while she ate Lisa's pussy. Tom fucked Lisa's mouth at the same time. Everyone came multiple times, bodies slick with sweat and cum. By the end, all four lay tangled on the bed, breathing hard, already talking about next weekend.
Lisa kissed Mark slow and deep. "That was the best swap smut we've ever had. Same time next Friday?" The others murmured agreement, already planning who would fuck who first.
