We'd talked about it a million times- we both wanted to fuck your new stepmom. She was hot, young, and just enough of a bitch to make her intriguing. When I found a way to swap bodies with anyone I wished, she was the first to come to mind. I set the stage, waited to get her alone and BAM, those huge titties were right in my hands. I even swapped your sister into her body for a minute, just to test my power. It took a minute to convince you to have a go- you didn't want to upset your dad. But the moment you touched her pussy, you knew it had all been worth it. After we'd both had our fun, we agreed to go back to normal and pretend it hadn't happened- but something was wrong. In my excitement, I had forgotten to mention that there was a limit to the number of swaps I could make; the less there were, the less control I had. I meant to swap you back, but your sister was back in your stepmom's body....and I don't think I can get her out.
