Jeremy the 20 something bachelor had a nice apartment in the city, a job, a girlfriend into exercising leaving her with a really nice body, and everyone thought he was a regular guy. For the most part they were right, but right as he started getting into puberty... and looked online and kinda got into one kink... and that got him into other kinks... and then more kinks... He was pretty perverted in his sexuality, but he mostly kept that out of the rest of his life. In fact he hadn't done much with his girlfriend sexually yet. Maybe a kiss or two, but he was a little afraid something might... slip out. Finding the device that changed genders however was just what he wanted. He could make any of his kinks normalized, and only a small portion of the population would think anything was off... Which kind of got his voyeurism kink going as he thought about whatever he wanted to do. Then just imagining what he could do with multiple changes where only 2% of 2% of people would even know what the original world was like. In his own apartment with some tissues nearby Jeremy got off easily with just that thought.
His heart beating and breathing hard Jeremy started to get the device working as he started editing the details of his gender of choice. Just having his changes all lined up was a ton of excitement. Was it even possible some simple looking gadget he was able to buy could change even everyone in the block or building? Jeremy exhaled and shook his head. No, he didn't go halfway with these things. Either it worked or it didn't. Jeremy pressed the button to initiate the changes. However what changes did he make to which gender?
