You guess that since the Gender Wave is a global phenomenon, you will eventually have to fuck a girl who used to be a guy if you don't want to stay virgin. So, why would you decline the offer of a girl that obviously has feelings for you?
You decide to accept but you can't do it in school. You decide to go to your house to have sex on your king sized bed. You take the shield with you just in case and quit the school with Jeff, who seems to get excited.
One week later, the wave had passed and the world was starting to work like normal again. Jeff was now known as Jessica and became your new girlfriend. You love your new life but you feel kind of bad for all the transformed people who don't manage to adapt to their new body and life so you joined an association that help those people. You also heard that a few people in the world didn't get changed... Some argues that they have a special anatomy that made them immuned to the wave but you would love to meet them so you can know if that's true or if they had some kind of shield like yours... Sadly, those unchanged people are scatered around the globe and it's very unlikely that you'll ever meet one of them.
Your physics teacher hired you as her new assistant because you're the one who created the shield and she thinks you might be able to find a way to reverse the wave's efects even though the media said it was permanent. Your best friend is kind of jealous that you didn't get transformed but you know he will accept it eventually. Greg is now a gorgeous girl but she somehow is still as boring as before.
Jessica is really happy with her new life. She's a goddess at bed and you wonder how she adapted so quickly. How can a former guy fuck this well as a girl? Anyway, you're not going to complain... You savor each instant with her and you know this will be a wonderful love story.
