One day I had a wild house party. After everyone left, you (my best friend) stayed with me to help clean. I was too tired, so I offered you to stay with me fot the night and we'll tidy up in the morning.We were chilling together, fiddling with our phones, when someone sent me a new interesting application to try that. It seems pretty stupid, called 'GenderSwap Pro Application'. I don't know, I've never heard of it. The description says that if you download it, give some information about yourself and scan your fingerprint and that of another person, after a while the app will helps you to swap your genders. I immediately thought it's a scam as there is no such thing. but you get really excited and say let's try it. Finally I agree so we download the app and test it but nothing happens... We decide to take a nap. The next day we wake up and feel very strange. We realize that the App worked and we are in each other's bodies! We get shocked and go completely crazy: we immediately want to try all dirty things to experience what it's like to be the opposite gender.We masturbate, fuck hard, experience orgasms together, then our perverted party end with a huge creampie. This App is really awesome!
