Request: A couple goes to a key swinger party, not knowing its a key swap party. Like in a normal key swinger party they throw in their house keys into a bowl and that take turns to draw a random key from their. Normally they would than go with the keys owner to their house and have some fun. But here they swap with the key owner. Than every participant goes with their bodies partner (somebody completely else) back to their house to have some fun.Little idea as the bodies are not cheating, maybe some people are justifying this way their faithfullness to their partner, which otherwise would be uncomfortable.

"What--?" Daniel staggered, catching himself on the couch. As he did so, a stranger's tits wobbled on his chest. Silky blonde hair hung down his face. A man towered over him, laughing."Weren't ready to become my wife, huh?"Daniel bit his lower lip. He and his wife had gone to a key swap party. Daniel thought he knew the rules: everyone threw their keys into a bowl and took turns picking them out and going home to fuck the owner of the keys. Only this one had an added twist. As soon as he pulled the keys out of the bowl - Mercedes keys attached to a pink fob - someone had shrieked laughter and then the world had spun. And then he was in someone else's body.The man helped him stand and Daniel gaped down at his tits."You like 'em, too, huh? This will be fun."Daniel blushed bright red. Was he expected to have sex with this guy?Others continued pulling keys out of the bowl and he watched as their bodies would stagger slightly as the mind within swapped. Daniel's wife came up to him, his former body on her arm. She covered her mouth in shock when she saw him."Oh, Daniel.""Don't worry," the man pulled Daniel close, "I'll take good care of him. I know exactly how to make her feel good."Daniel was in a state of shock all the way back to the man's home. But he was true to his word. It was weird at first having a strange man diving between his legs, but Daniel's pussy soon grew wet beneath the man's tongue and his body shook with orgasm.After that, it was time to try out his new body on top.
