I am sitting on the couch with you. We took a serum a hour ago, now all we need to do is join hands and chant the spell and we will swap bodies. I am so excited to be a guy for a short time. We join hands and start chanting. We experience a stabbing pain in our heads, then its fades.......You open your eyes. Holly , it worked. Emma is bouncing up and down in your body and says her bladder is full. You laugh at her and tell her to go ahead and go to the bathroom and go pee. While she is gone you start to touch her tits. Holly , this is so weird so you strip out of Emmas clothes. You can't believe you are in Emmas body. Its so soft. Emma comes back from the bathroom and catch you rubbing all over her, now your body. She tells you to stop, but you notice she has a hard-on. She must have shook your dick to many times after peeing. You lay down and Emma straddles your body. Emma is fucking you with your own dick but my god does it feel good. Lets cum together!
